[0001] The invention relates to an electrical connector having a shroud at a mating end
of the connector and a board mount system. More particularly, the invention relates
to an electrical connector having an insulating housing including a plurality of first
contacts in a shroud, the housing further includes a board mount system for mounting
the housing to a printed circuit board.
[0002] A known electrical connector disclosed in U.S. 5,129,831 ('831), comprises; an insulative
housing, a shroud at a mating end of the housing, and multiple electrical contacts
within the shroud and projecting toward the mating end. The shroud protects the contacts
and assists in aligning the known connector during connection with a complementary
connector. Keying elements on both the known connector and the complementary connector
allow connection of the connectors when the connectors are oriented with the keying
elements aligned with one another. The connector of the '831 reference has the advantage
of being capable of using a keying protrusion to assure that the appropriate right
angle connector is mounted to a corresponding location on a circuit board. The '831
reference has a disadvantage in that it does not provide for a plurality of different
types of contacts in the housing or a short circuit bar.
[0003] Furthermore, a known board mount disclosed in U. S. 4, 907,987, is fabricated from
a metal stamping and comprises; a metal board lock formed with a slotted post defined
by two barbed spring members extending along opposite sides of a slot having closed
ends that join the spring members. A known electrical connector disclosed in U.S.
4,907,987, comprises; an insulative housing, multiple electrical contacts within the
housing projecting toward a mating end of the connector, and a board mount comprising,
a metal board lock assembled in an aperture of the housing, the board lock being comprised
of a slotted post for insertion in an aperture of a circuit board.
[0004] An assembly is advantageously constructed by stacking the housing on the circuit
board. In the assembly, the housing has a construction that determines the depth of
insertion of the post in the aperture, and the housing receives an insertion force
that is applied to insert the post.
[0005] Such an assembly has the disadvantage of being relatively tall in height, due to
the height of the housing being added to a thickness of the circuit board. The assembly
can be reduced in height by mounting the housing within a plane of thickness of the
circuit board. To do so would require the board lock itself to have a construction
that determines the depth of insertion of the post, and a construction that receives
the insertion force, the force required to insert the post.
[0006] The present invention consists in an electrical connector having an insulating housing
including a plurality of contacts in a shroud, and a board mounting system for mounting
the housing to a printed circuit board, characterised in that the board mounting system
comprises a board mount which is a stamped piece and which is anchored to the housing
at one end and includes a first flange for engaging the circuit board, a post projecting
from the first flange for insertion into an aperture in the circuit board, and a second
flange extending transversely to the longitudinal axis of the post and serving as
a force receiving surface on which an insertion force is applied to insert the post
into the board aperture.
[0007] The invention also consists in a board mount for mounting an electrical connector
to a printed circuit board and which is a metal stamping capable of being anchored
at one end to the connector housing, comprising a first flange for engaging the circuit
board, a post projecting from the first flange for insertion into an aperture of the
circuit board, and a second flange extending transversely to the longitudinal axis
of the post and serving as a force receiving surface on which an insertion force is
applied to insert the post into the aperture of the circuit board.

[0009] With reference to Figure 1, an electrical connector
1 comprises, an insulative housing
2 of unitary molded plastic construction, a shroud
3 at a mating end
4 of the housing 2, and multiple electrical contacts
5 (Figures 2 and 8) within the shroud 3 projecting toward the mating end 4. The contacts
5 are within a cavity
6 defined by the shroud 3. A board mount
7 on the housing 2 connects the housing 2 with a circuit board
8 (Figure 7).
[0010] With reference to Figure 8, each of the contacts 5 is conductive and will now be
described. Each contact 5 is of unitary construction obtained by being stamped and
formed from a strip (not shown) of conductive metal. Each contact 5 comprises, a front
pin
9 of 0.5 mm square cross section, a wider stepped portion
10 and a rear solder terminal
11 with a contact surface
12 for connection to one of multiple conductive pads
13 (Figure 7) of the circuit board 8. The contact surface 12 is convex curved for establishing
a surface mount connection with a conductive pad 13. Alternatively, the contact surface
12 can be on a solder terminal 11 shaped as a post (not shown) for establishing a
connection in a plated through hole of a circuit board (not shown).
[0011] In the cavity 6 of the shroud 3, the pins 9 of the multiple contacts 5 are arranged
in two rows, a top row
14 and a bottom row
15 (Figure 6). The pins 9 are on 2.0 mm. pitch spacing, meaning that the centerlines
of the pins 9 are spaced apart 2.0 mm. Consequently, the centerlines of the two rows
14, 15 are spaced apart 2.0 mm. Each pin 9 of the top row 14 is directly aligned with
a pin 9 in the bottom row 15.
[0012] The solder terminal 11 of each contact 5 projects from a rear of the housing 2. The
solder terminals 11 of the contacts 5 in the bottom row 15 bend upward to engage a
first row
16 of the pads 13 near an edge
17 of the circuit board 8. The solder terminals 11 of the contacts 5 in the bottom row
15, being longer than those of the contacts 5 in the top row 14, bend upward to engage
a second row
18 of the pads 13 farther from the edge 17 of the circuit board 8.
[0013] The solder terminal 11 of each contact 5 in the top row 14 is offset laterally from
the centerline of the pin 9 of the same contact 5. Thereby, a solder terminal 11 of
each contact 5 in the bottom row 15 can bend upward without engaging a solder terminal
11 of a contact 5 in the top row 14. The solder terminals 11 of the contacts 5 in
one of the rows 14, 15 are offset laterally with respect to the solder terminals 11
of the contacts 5 in the other of the rows 14, 15.
[0014] With reference to Figure 1, an electrical plug
19 is a complementary connector adapted for mating connection with the connector 1.
The periphery of the shroud 3 is shaped to interfit with the complementary shaped
periphery of the plug 19. The shroud 3 assists in aligning the connector 1 during
connection with the electrical plug 19. The plug 19 contains electrical contacts (not
shown) for mating with the pins 9, such contacts being connected to respective electrical
wires
20 terminated with the plug 19. Multiple openings
21 extend through respective sides
22, 23 of the shroud 3 beside one of the rows 14, 15 of the pins 9. The openings 21 are
distributed about a periphery of the shroud 3. All of the openings 21 extend through
the mating end 4 of the connector 1 and extend rearward from the mating end 4. One
of the openings 21 is a keyway located along one side 22 of the shroud 3, and is shaped
to interfit with a complementary shaped, projecting key
24 on the plug 19. The plug 19 will connect with the connector 1 only when the key 24
is aligned with the keyway, because no other side 23 of the shroud 3 has an opening
21 in a location which will be aligned with the key 24 when the plug 19 is attempted
to be inserted into the shroud 3.
[0015] With reference to Figures 11 and 12, a shorting bar
25 comprises, a conductive metal strip
26 with end spring fingers
27 within an insulative sheath
28, fabricated by insert molding. The shorting bar 25 is adapted to be inserted into
the cavity 6 of the shroud 3. The metal strip 26 bridges between a pair of the pins
9 with the fingers 27 frictionally engaging the pair of pins 9 to connect them electrically.
The shorting bar 25 is adapted for being positioned at a selected one of multiple
positions
29, some of which are indicated by dotted lines, interconnecting electrically at least
two of the pins 9 in the two rows 14, 15. Since the centerlines of the fingers 27
are 2 mm. apart, they can connect with any pair of the pins 9 on 2 mm. pitch spacings.
The multiple openings 21 through the shroud allow for entry of an extraction tool
30 to remove the shorting bar 25. Each of the multiple positions 29 of the shorting
bar 25 is aligned with at least one of the openings 21, such that the extraction tool
30 can enter the opening 21 and pry the shorting bar 21 away from the pair of pins
9.
[0016] The shroud 3 is one of multiple shrouds 3,
31 at the mating end 4 of the housing 2. The multiple shrouds 3, 31 are of different
peripheral shapes and contain electrical contacts 5,
32 of different shapes. For example, the shroud 3 is rectangular and is contiguous at
the mating end 4 of the connector 1 with the shroud 31 with a periphery that is rectangular
with two diagonal chamfered corners
33. The contacts 32 within the shroud 31 are arranged four in a row. Each of the contacts
32 (Figure 9) is of unitary construction, stamped and formed from metal strip, having
a bulbous front end
34 and a solder terminal
35 projecting from a rear of the housing 2. The solder terminal 35 is curved with a
contact surface
36 for engaging one of the four solder pads
37 on the circuit board 8. For example, the contacts 32 comprise, 0.84 mm. diameter
pins on 0.200 mm. pitch spacing.
[0017] The connector 1 further may be unitary with an unshrouded connector
38 with a generally D shaped periphery at the mating end 4 of the connector 1. The unshrouded
connector 38 is separated by a clearance space
39 from the shroud 3. Electrical contacts
40 within the connector 38 are arranged in two rows, a top row
41, and a bottom row
42. Each of the contacts 40 is of unitary construction, stamped and formed from metal
strip. Each of the contacts 40 comprises, an electrical receptacle
43 defined by a pair of opposed spring fingers
44, a middle portion
45 with barbs
46 along opposite edges
47, and solder terminals
48 projecting from a rear of the housing 2 for connection to a pad 13' in a row 16'
or 18'. For example, the connector 38 can be a 68 position receptacle connector with
the contacts 40 on 0.50 mm pitch spacing.
[0018] The solder terminal 48 of each contact 40 in the bottom row 42 is offset laterally
from the centerline of the receptacle 43 of the same contact 40. Thereby, a solder
terminal 48 of each contact 40 in the bottom row 42 can bend upward without engaging
a solder terminal 48 of a contact 40 in the top row 41. The solder terminals 48 of
the contacts 40 in one row are offset laterally with respect to the solder terminals
48 of the contacts 40 in the other row.
[0019] With reference to Figure 13, further details of an embodiment of the board mount
7' will be described. The board mount 7' is fabricated from a one piece metal stamping.
A metal board lock of the board mount 7' comprises, a slotted post
19' defined by two barbed spring members
20' extending along opposite sides of a slot
21' having closed ends that join the spring members 20'. The post 19' is adapted for
insertion into the aperture 10' of the circuit board 8'. The post 19' is dimensioned
with a width having an interference fit within the aperture 10' of the circuit board
8'. Further details of the post 10' and interaction with the aperture 10' are described
in U. S. 4,907,987.
[0020] The board mount 7' further comprises, a web
22' having a first edge
23' and a second edge
24'. The first edge 23' defines a periphery of both, the post 19', and a first flange
25' extending transverse to a longitudinal axis of the post 19'. The post 19' projects
in a plane defined by the thickness of the web 22'. The first flange 25' is turned
outwardly of the plane of the web 22', and is transverse to the plane of the web 22'
for engaging the circuit board 8', and, more particularly, to engage one of the pads
9'. Molten solder (not shown) is used to join the first flange 25' to the pad 9'.
The first edge 23' along the first flange 25' has a wavy shape for amassing the molten
solder, and for distributing the molten solder along the surface of the first flange
25'. The second edge 24' defines a second flange
26' turned outwardly of the plane of the web 22' to extend transverse to the longitudinal
axis of the post 19'. The second flange 26' extends over the axis of the post 19',
and provides a force receiving, pressure plate against which an insertion force is
pressed to insert the post 19' with an interference fit in one of the apertures 10'
of the circuit board 8'.
[0021] The web 22' is contiguous with a coplanar anchor fluke
27' that extends outwardly beside the first flange 25' and the second flange 26'. An
opening
28' extends through the fluke 27'. The housing 2' is of unitary construction, for example,
by molding a polymer known as an LCP, liquid crystalline polymer. With reference to
Figures 14 through 17, an assembly of the housing 2' and the board mount 7' can be
fabricated by insert molding, such that the housing 2' is molded unitarily with the
board mount 7', and such that the housing 2' extends through the opening 28' in the
fluke 27'. In an embodiment shown in Figure 17, the opening 28' communicates with
an edge of the fluke 27'. Core pin openings
29' extend through the housing 2' to intersect the fluke 27'. Thereby, the fluke 27'
anchors the board mount 7' to the housing 2'. The web 22' and the first flange 25'
and the second flange 26' and the post 19' project from a rear of the housing 2'.
A notch
30' at an intersection of the second flange 26' and the fluke 27' permits turning of
the flange 26' outwardly.
[0022] A finger
33' on the housing 2' projects from the housing 2', and overlies the second flange 26'
and a portion of the web 22' adjacent the second flange 26'. The finger 33' is wider
than the second flange 26', and provides a cushion against which an insertion force
is applied. The cushion is particularly useful for reducing discomfort when an operator
applies the insertion force by manual labor without the use of a tool to apply the
insertion force. For example, the finger 33' can be fabricated unitarily with the
housing 2'. The finger 33' partially envelops the second flange 26', adding strength
to a connection of the finger 33' and the second flange 26'.
[0023] With reference to Figures 14 and 16, a hook
34' on the fluke 27' projects from the housing 2'. A circuit board receiving space between
the hook 34' and the first flange 25' is adapted to receive the edge 17' of the circuit
board 8' between the hook 34' and the first flange 25'. The hook 34' and the first
flange 25', across the width of the space, spans a thickness of the circuit board
8'. A third edge
43' along the fluke 27' extends beside the hook 34' and extends from the hook 34' to
an intersection of the third edge 43' with the first edge 23'. A notch
44' at the intersection separates an inner end of the first flange 25' from the third
edge 43' and from the fluke 27'. The third edge 43' is adapted to stop against the
edge 17' of the circuit board 8', and provides a pivot. The third edge 43' registers
in a rounded notch 17'' in the edge 17' of the circuit board 17', and quickly locates
the aperture 10' and the post 19' in mutual alignment for insertion of the post 19'
into the aperture 10' when the third edge 43' is against the notch 17'' in the edge
17' of the circuit board 8'. When the board mount 7' is pivoted relative to the circuit
board 8', and an insertion force is applied to the second flange 26', the aligned
post 19' and aperture 10' are assembled with an interference fit, as shown in phantom
outline in Figures 14, 16 and 17.
[0024] With reference to Figures 14 and 16, a circuit board 8' must be positioned at an
angle of elevation to pass over the post 19' and under the hook 34'. In the embodiment
of Figure 16, the post 19" is taller than the post 19' in the embodiment of Figure
15. While the taller post 19" is capable of interfitting with a circuit board 8' of
relatively larger thickness than is the shorter post 19', the circuit board 8' of
Figure 16 is positioned at a relatively larger angle of elevation, particularly when
the circuit board 8' of Figure 16 is thicker than the circuit board 8' of Figure 15.
[0025] A tip of the hook 34' in the embodiment of Figure 16 has an undercut clearance
45' to allow for insertion of the circuit board 8', positioned at an angle of elevation,
into the clearance space. A curved end
46' on the hook 19', next to the undercut clearance 45', engages the circuit board 8',
particularly when the post 19' is interfit within the aperture 10', as shown in phantom
outline. In the embodiment shown in Figure 17, a hook 34 is absent. The third edge
43' provides a stop for the edge 17' of the circuit board 8'. The third edge 43' can
provide a pivot, although the post 19' can be interfit with the aperture 10', either
by pivoting, as described with reference to Figures 15 and 16, or by sliding the third
edge 43' along the edge of the circuit board 8'.
