BACKGROUND OF THE INVENTION
[0001] The present invention relates to a connector, in particular, to a connector having
a structure in which a connector housing for accommodating a conductive contact is
held by a frame.
[0002] As a connector of this type, for example,
JP 08-115766 A discloses a connector 1 as illustrated in FIG. 12. The connector 1 has a structure
in which a connector housing 4 is inserted and held in an accommodation hole 3 of
a frame 2. The connector housing 4 is provided on an outer surface thereof with a
projection 5, while the frame 2 is provided with a lance 6 that protrudes into the
accommodation hole 3 and extends in an insertion direction of the connector housing
4. When the connector housing 4 is inserted into the accommodation hole 3 of the frame
2, the projection 5 of the connector housing 4 advances forward, while elastically
deforming the lance 6 inside the accommodation hole 3, until the front face of the
connector housing 4 abuts an abutment face 7 inside the accommodation hole 3. At this
time, the projection 5 runs over the lance 6, and the lance 6 goes back to the original
position due to its elastic force, to thereby open toward the inside of the accommodation
hole 3. Accordingly, the projection 5 is caught by the lance 6, whereby the connector
housing 4 can be prevented from falling off the accommodation hole 3 of the frame
2.
[0003] Once the connector housing 4 of the connector 1 is fitted with a connector housing
9 of a counter connector 8, a conductive contact (not shown) that is mounted on the
connector housing 4 of the connector 1 is electrically connected to another conductive
contact (not shown) that is mounted on the connector housing 9 of the counter connector
8.
[0004] However, in order for the connector housing 4 to be firmly held in the accommodation
hole 3 of the frame 2, the lance 6 extending in the insertion direction of the connector
housing 4 has to have such a length as to undergo a sufficient elastic deformation.
Hence, it has been difficult to reduce a size of the connector 1.
[0006] EP 0 700 124 A2 describes an electrical contact having improved locking lances.
SUMMARY OF THE INVENTION
[0007] The present invention has been made in order to solve the conventional problem described
above and is aimed at providing a connector capable of reducing the size thereof while
the connector housing is firmly held by the frame.
[0008] The invention is defined in claim 1, and preferred embodiments are further defined
in the dependent claims. A connector according to the present invention comprises:
a frame including a connector-housing accommodation portion; and a connector housing
held at a housing holding position where at least a part of the connector housing
is inserted in the connector-housing accommodation portion of the frame, the connector
housing accommodating a conductive contact, wherein either one of the connector-housing
accommodation portion of the frame and the connector housing includes a spring portion
capable of elastically deforming and a lance capable of elastically deforming disposed
on a surface of the spring portion and extending from the spring portion in an insertion
direction of the connector housing, wherein the other one of the connector-housing
accommodation portion of the frame and the connector housing includes a lance-opposing
surface facing a tip end of the lance in the insertion direction of the connector
housing, and wherein the tip end of the lance is caught by the lance-opposing surface
to prevent the connector housing from falling off the frame.
[0009] The spring portion has a shape of a beam extending in a direction orthogonal to the
insertion direction of the connector housing and having both ends of the beam fixed,
and the lance has a cantilever shape extending from a center part of the spring portion
in the insertion direction of the connector housing.
[0010] It is preferable that the spring portion and the lance elastically deform when at
least a part of the connector housing is inserted in the connector-housing accommodation
portion, and are freed from elastic deformation when the connector housing is held
at the housing holding position. Further, preferably, the spring portion elastically
deforms such that the spring portion twists around a center axis thereof extending
orthogonally to the insertion direction of the connector housing and that the center
axis bends.
[0011] Preferably, the either one of the connector-housing accommodation portion of the
frame and the connector housing includes: an opposing wall facing a surface of the
spring portion on the opposite side from the lance; a first interference surface formed
on the spring portion; and a second interference surface formed on the opposing wall
so as to correspond to the first interference surface, and when the connector housing
and the frame are applied with a force to draw one from the other, the first interference
surface and the second interference surface interfere with each other to suppress
deformation of the spring portion.
[0012] The first interference surface may be constituted of a part of a first projection
formed on the spring portion so as to project toward the opposing wall, and the second
interference surface may be constituted of a part of a second projection formed on
the opposing wall so as to project toward the spring portion.
[0013] Preferably, either one of the first interference surface and the second interference
surface faces in the insertion direction of the connector housing, and the other one
of the first interference surface and the second interference surface faces in a direction
opposite from the insertion direction of the connector housing.
[0014] Preferably, the frame and the connector housing include respectively a frame-side
stopper and a housing-side stopper that abut to one another when the connector housing
is held at the housing holding position to limit movement of the connector housing
in the insertion direction.
[0015] It is preferable that the connector housing is held at the housing holding position
so as to be movable in a plane that is perpendicular to the insertion direction of
the connector housing.
[0016] Preferably, the frame includes a fixing portion that fixes the frame to an object
to be connected.

DETAILED DESCRIPTION OF THE INVENTION
[0018] An embodiment of the present invention will be described below based on the appended
drawings.
[0019] FIGS. 1A to 1D illustrate a configuration of a connector 11 according to the embodiment.
The connector 11 electrically detects fitting, and includes a frame 12 and a connector
housing 13 that is held by the frame 12. The frame 12 is a plate-like member that
is fixed to an object to be connected (not shown), and has in its center a connector-housing
accommodation portion 12A that is a substantially rectangular through-hole and, on
both sides of the connector-housing accommodation portion 12A, fixing portions 12B
that are a pair of circular through-holes and that fix the frame 12 to the object
to be connected.
[0020] The connector housing 13 is a columnar member that extends in a direction perpendicular
to the plate-like frame 12. A part of the connector housing 13 is inserted in the
connector-housing accommodation portion 12A of the frame 12, whereby the connector
housing 13 is positioned at a housing holding position P and held by the frame 12.
[0021] For the sake of convenience, a direction connecting the pair of fixing portions 12B
of the frame 12 is referred to as X direction, a direction in which the connector
housing 13 extends is referred to as Z direction, and a direction orthogonal to the
X direction and the Z direction is referred to as Y direction.
[0022] FIGS. 2A to 2D illustrate the configuration of the frame 12. The frame 12 has a pair
of beam-like spring portions 14 that are respectively disposed in an end part in the
+Y direction and in another end part in the -Y direction of the connector-housing
accommodation portion 12A. Each of the spring portions 14 extends in the X direction,
has both ends thereof fixed to the frame 12 and can elastically deform.
[0023] In addition, each of the spring portions 14 is provided on the surface of its center
part with an elastically deformable lance 15 in a cantilever shape that protrudes
in the Y direction toward the inside of the connector-housing accommodation portion
12A and extends in the +Z direction.
[0024] Moreover, the frame 12 has opposing walls 16 each of which faces the surface of the
corresponding spring portion 14 facing in the Y direction on the opposite side from
the lance 15.
[0025] In other words, the frame 12 has slits 17 extending in the X direction and disposed
respectively in an end part in the +Y direction and in another end part in the -Y
direction of the frame 12, and the spring portion 14 and the corresponding opposing
wall 16 that face each other in the Y direction are shaped by one of the slits 17,
while the lance 15 is formed on the surface of the spring portion 14 on the opposite
side from the opposing wall 16.
[0026] The frame 12 is also provided with frame-side stoppers 18 that are planar surfaces
facing in the -Z direction and respectively disposed at an end on the +X direction
side and at another end on the -X direction side in the connector-housing accommodation
portion 12A.
[0027] As illustrated in FIG. 2B, one of the frame-side stoppers 18 disposed at the end
on the -X direction side in the connector-housing accommodation portion 12A continuously
extends in the Y direction without being divided at the center thereof, whereas the
other frame-side stopper 18 disposed at the other end on the +X direction side in
the connector-housing accommodation portion 12A has a notch 18A at the center thereof,
being divided into a portion on the +Y direction side and another portion on the -Y
direction side by the notch 18A.
[0028] As illustrated in FIG. 3, each of the lances 15 formed on the surfaces of the spring
portions 14 has a cantilever shape protruding in the Y direction toward the inside
of the connector-housing accommodation portion 12A and extending in the +Z direction,
while each of the spring portions 14 extending in the X direction has a beam shape
with both ends thereof fixed to the frame 12. Accordingly, during insertion of the
connector housing 13 into the connector-housing accommodation portion 12A from the
-Z direction to the +Z direction, as a tip end 15A that is a free end of each of the
lances 15 comes into contact with the connector housing 13 and receives a force in
the Y direction toward the corresponding opposing wall 16, not only each of the lances
15 elastically deforms in the Y direction, but also the spring portion 14 holding
the lance 15 and extending in the X direction elastically deforms so as to twist around
a center axis C1 and cause the center axis C1 bend toward the Y direction, supposing
that the spring portion 14 has the center axis C1 extending in the X direction along
the spring portion 14. Therefore, even if the lance 15 has a short length in the Z
direction, elastic deformation of the lance 15 and elastic deformation of the spring
portion 14 simultaneously occur, whereby the tip end 15A of the lance 15 can largely
shift in the Y direction.
[0029] Moreover, as illustrated in FIG. 4, each of the spring portions 14 is provided with
a first projection 19 that is formed on the surface of the spring portion 14 on the
opposite side from the lance 15 so as to project in the Y direction toward the corresponding
opposing wall 16, whereas the opposing wall 16 is provided with a second projection
20 that is formed so as to project in the Y direction toward the spring portion 14.
The first projection 19 and the second projection 20 are disposed at the same position
in the X direction, while the second projection 20 is located slightly away from the
first projection 19 on the -Z direction side.
[0030] Furthermore, the first projection 19 is provided with a first interference surface
19A facing in the -Z direction, while the second projection 20 is provided with a
second interference surface 20A facing in the +Z direction, the first interference
surface 19A and the second interference surface 20A being disposed slightly apart
from each other in the Y direction and the Z direction.
[0031] As illustrated in FIG. 5, the connector housing 13 has a columnar housing main body
21 extending in the Z direction, the housing main body 21 is provided at an end in
the +Y direction and at the other end in the -Y direction thereof on the -Z direction
side respectively with a pair of lance accommodation portions 22 in a convex shape
corresponding to the pair of lances 15 of the frame 12, and each of the lance accommodation
portions 22 is provided at an end in the +Z direction with a lance-opposing surface
23 facing in the -Z direction and parallel to the XY plane. When the connector housing
13 is held by the frame 12, each of the lance accommodation portions 22 accommodates
the corresponding lance 15 of the frame 12, while each of the the lance-opposing surfaces
23 faces the tip end 15A of the corresponding lance 15 of the frame 12.
[0032] The housing main body 21 is provided at an end in the +X direction and the other
end in the -X direction thereof on the -Z direction side respectively with overhang
portions 24 overhanging in the +X direction and the -X direction, and surfaces of
the overhang portions 24 on the +Z direction side constitute housing-side stoppers
25 that are planar surfaces facing in the +Z direction. The housing-side stoppers
25 abut the frame-side stoppers 18 of the frame 12 when the connector housing 13 is
held by the frame 12, thereby limiting the position of the connector housing 13 in
the Z direction.
[0033] In addition, the housing main body 21 is provided on the side surface thereof on
the +X direction side with a protrusion 26 extending in the Z direction and protruding
in the +X direction. The protrusion 26 is not formed on the other side surface on
the -X direction side of the housing main body 21 and is inserted in the notch 18A
of the frame 12 when the connector housing 13 is held by the frame 12, thereby preventing
the connector housing 13 from being incorrectly attached to the frame 12.
[0034] As illustrated in FIG. 6, the connector housing 13 is provided with a counter-connector
accommodation portion 27 that is open toward the +Z direction and accommodates a conductive
contact 28. The conductive contact 28 branches into two portions, that is, two tip
portions 28A each extending in the +Z direction inside the counter-connector accommodation
portion 27. The tip portions 28A are apart from each other in the X direction, while
only one of the tip portions 28A is visible in FIG. 6.
[0035] A thickness dimension T1 of the connector housing 13 in the Y direction at the pair
of the lance accommodation portions 22 is set to be smaller than a dimension of a
distance between the tip ends 15A of the pair of lances 15 of the frame 12, whereas
a thickness dimension T2 of the housing main body 21 in the Y direction on the +Z
direction side from the lance accommodation portions 22 is set to be smaller than
a dimension of a distance between the pair of spring portions 14 of the frame 12 and
larger than a distance between the tip ends 15A of the pair of lances 15 of the frame
12.
[0036] When the connector housing 13 is attached to the frame 12, the connector housing
13 is inserted into the connector-housing accommodation portion 12A of the frame 12
from the -Z direction to the +Z direction as illustrated in FIG. 7. In this process,
since the thickness dimension T2 of the housing main body 21 of the connector housing
13 in the Y direction is set to be smaller than the dimension of the distance between
the pair of spring portions 14 of the frame 12 and larger than the distance between
the tip ends 15A of the pair of lances 15, both side surfaces of the housing main
body 21 in the Y direction respectively come into contact with the corresponding lances
15 of the frame 12, whereby each of the tip ends 15A of the lances 15 is applied with
a force acting in the Y direction outward from the connector-housing accommodation
portion 12A. Accordingly, the lances 15 elastically deform in the Y direction and,
at the same time, the spring portions 14 holding the lances 15 elastically deform
such that each of the spring portions 14 twists around the center axis C1 thereof
extending in the X direction and that the center axis C1 bends in the Y direction,
while the housing main body 21 of the connector housing 13 advances in the +Z direction
as passing between the tip ends 15A of the pair of lances 15 of the frame 12.
[0037] In addition, the connector housing 13 is inserted while having the protrusion 26
on the side surface of the housing main body 21 of the connector housing 13 on the
+X direction side inserted in the notch 18A of the frame 12. Hence, the connector
housing 13 having the protrusion 26 to face in the -X direction cannot be inserted
into the connector-housing accommodation portion 12A of the frame 12 since the protrusion
26 interferes with the frame-side stopper 18 of the frame 12, whereby the connector
housing 13 can be prevented from being attached to the frame 12 in an incorrect orientation.
[0038] Moreover, when the pair of housing-side stoppers 25 of the connector housing 13 abut
the frame-side stoppers 18 of the frame 12, insertion of the connector housing 13
into the connector-housing accommodation portion 12A of the frame 12 is stopped, being
limited such that the connector housing 13 is prevented from further advancing in
the +Z direction.
[0039] At this time, as illustrated in FIG. 8, the pair of lances 15 of the frame 12 are
respectively accommodated in the corresponding lance accommodation portions 22 of
the connector housing 13. Since the thickness dimension T1 of the connector housing
13 in the Y direction at the pair of lance accommodation portions 22 is set to be
smaller than the dimension of the distance between the tip ends 15A of the pair of
lances 15 of the frame 12, the lances 15 are accommodated in the lance accommodation
portions 22 respectively so as to be freed from elastic deformation and return to
the original state before insertion of the connector housing 13, whereby the tip ends
15A of the lances 15 face the corresponding lance-opposing surfaces 23 of the connector
housing 13.
[0040] Because the tip ends 15A of the lances 15 are caught by the lance-opposing surfaces
23, the connector housing 13 is prevented from falling off the frame 12 in the -Z
direction.
[0041] In this way, insertion of the connector housing 13 in the +Z direction is limited
through abutment of the housing-side stoppers 25 of the connector housing 13 to the
frame-side stoppers 18 of the frame 12, and the tip ends 15A of the lances 15 are
caught by the lance-opposing surfaces 23 so as to prevent the connector housing 13
from falling off in the -Z direction, whereby the connector housing 13 is held by
the frame 12 and positioned at the housing holding position P where an end portion
of the connector housing 13 on the -Z direction side is inserted in the connector-housing
accommodation portion 12A of the frame 12.
[0042] Although movements in the +Z direction and the -Z direction of the connector housing
13 positioned at the housing holding position P are limited, a predetermined distance
is given each between the side surface of the housing main body 21 and the edge portion
of the connector-housing accommodation portion 12A of the frame 12 and between the
lateral face of each of the lance accommodation portions 22 and the tip end 15A of
the corresponding lance 15 of the frame 12 as illustrated in FIG. 8, so the connector
housing 13 is held by the frame 12 such that the connector housing 13 can move within
the range of the above-described distances along the XY plane perpendicular to the
insertion direction of the connector housing 13. In other words, the frame 12 and
the connector housing 13 together form a so-called floating structure.
[0043] When the connector housing 13 is positioned at the housing holding position P, the
pair of lances 15 and the pair of spring portions 14 of the frame 12 are back in the
original state with no elastic deformation so that the first interference surface
19A formed on each of the spring portions 14 and the second interference surface 20A
formed on the corresponding opposing wall 16 are located slightly away from each other
in the Y direction and the Z direction.
[0044] When the connector housing 13 positioned at the housing holding position P and the
frame 12 are applied with a force to pull one away from the other, such as when a
force to pull the connector housing 13 from the housing holding position P is applied,
the tip ends 15A of the pair of lances 15 of the frame 12 are caught by the pair of
lance opposing surfaces 23 of the connector housing 13, and if the force is large,
the tip ends 15A of the lances 15 are pulled up in the -Z direction by the lance opposing
surfaces 23 of the connector housing 13 as illustrated in FIG. 9.
[0045] At this time, since the spring portions 14 hold the base parts of the lances 15,
moments around the center axis C1 act on each of the spring portions 14, and at the
same time, the force in the Y direction toward the corresponding opposing wall 16
and the force in the -Z direction to pull upward are applied on the spring portion
14, whereby the spring portion 14 elastically deforms in the Y direction and the -Z
direction as twisting around the center axis C1, and the first interference surface
19A formed on the spring portion 14 comes into contact with the second interference
surface 20A formed on the corresponding opposing wall 16.
[0046] Since each of the first interference surfaces 19A and the corresponding second interference
surface 20A interfere with each other in this manner, the spring portions 14 are prevented
from further elastically deforming, whereby the connector housing 13 is restrained
from moving in the -Z direction.
[0047] The force that acted from the connector housing 13 on the tip ends 15A of the lances
15 is transmitted to the spring portions 14 and is then received by the second interference
surfaces 20A of the opposing walls 16 via the first interference surfaces 19A. Therefore,
the amount of deformation of the lances 15 and the spring portions 14 is reduced,
and there is an effect of improving breaking strength of the lances 15 and the spring
portions 14.
[0048] In the connector 11 according to the embodiment, since the frame 12 includes the
spring portions 14 extending in the X direction and the lances 15 extending from the
surfaces of the spring portions 14 in the Z direction, even if the length of each
of the lances 15 in the Z direction is short, the lances 15 and the spring portions
14 simultaneously undergo elastic deformation so that the tip ends 15A of the lances
15 can largely move in the Y direction. Accordingly, it is possible to realize a connector
having a short length in the Z direction that is the insertion direction of the connector
housing 13, while the connector housing 13 is firmly held by the frame 12.
[0049] FIGS. 10A and 10B illustrate a counter connector 31 with which the connector 11 according
to the embodiment is fitted.
[0050] The counter connector 31 includes a frame 32 and a connector housing 33 that is integrally
formed with the frame 32 so as to protrude from the surface of the frame 32. The frame
32 is a plate-like member that is fixed to a counter-side object to be connected (not
shown) and is provided at both ends thereof with fixing portions 34 that are a pair
of circular through-holes for being fixed to the counter-side object to be connected.
The connector housing 33 is a columnar member extending in a perpendicular direction
to the plate-like frame 32 and is provided with two insertion holes 35 that are parallel
to each other and extend in a perpendicular direction to the frame 32; conductive
contacts 36 are respectively accommodated and held in the insertion holes 35.
[0051] When used, while the connector 11 is fixed to the object to be connected (not shown)
by means of the pair of fixing portions 12B of the frame 12, and the counter connector
31 is fixed to the counter-side object to be connected (not shown) by means of the
pair of fixing portions 34 of the frame 32, the connector housing 33 of the counter
connector 31 is inserted in the counter-connector accommodation portion 27 of the
connector housing 13 of the connector 11, whereby the connector 11 and the counter
connector 31 are fitted with each other as illustrated in FIGS. 11A and 11B.
[0052] At this time, since the connector housing 13 of the connector 11 is held by the frame
12 so as to be movable in the XY plane, even if the frame 12 and the frame 32 are
misaligned from one another due to a variation between the fixing position of the
frame 12 to the object to be connected and the fixing position of the frame 32 to
the counter-side object to be connected, a variation in relative positions between
the object to be connected and the counter-object to be connected, and the like, the
connector housing 13 moves in the XY plane with respect to the frame 12, whereby the
connector housing 13 of the connector 11 is positionally adjusted to the connector
housing 33 of the counter connector 31, allowing the connector 11 to be fitted with
the counter connector 31.
[0053] Once the connector 11 is fitted with the counter connector 31, the pair of tip portions
28A of the conductive contact 28 held by the connector housing 13 of the connector
11 come into contact with the pair of conductive contacts 36 held by the connector
housing 33 of the counter connector 31, causing the pair of conductive contacts 36
of the counter connector 31 to short-circuit via the conductive contact 28 of the
connector 11. Fitting of the connectors can be electrically detected in this manner.
[0054] In the above-described embodiment, the frame 12 includes the spring portions 14 and
the lances 15, whereas the connector housing 13 includes the lance accommodation portions
22 and the lance-opposing walls 23. Conversely, however, even if the connector housing
13 is provided with the spring portions 14 and the lances 15, and the frame 12 is
provided with the lance accommodation portions 22 and the lance-opposing walls 23,
a connector in a small size can be realized while the connector housing 13 is firmly
held by the frame 12 in the same manner.
[0055] Moreover, in the above-described embodiment, the spring portions 14 of the frame
12 each have a beam-like shape with both ends thereof being fixed.
[0056] The connector 11 according to the embodiment described above is a fitting-detecting
connector for electrically detecting fitting. However, this is not the sole case,
and the present invention can be similarly applied to a circuit connector that is
used for connection of electrical signals.
