[0001] The present invention relates to a coupling arrangement for releasably latching together
two parts of a cable contact connector assembly, said coupling arrangement comprising;
two coupling members each including a latching arm having a latch ramp surface
formed thereon and locking ramp means for sliding engagement, in a direction substantially
circumferential with respect to an axis of said cable contact connector assembly,
with a latch ramp surface formed on a latching arm of the other said coupling member;
detent means being provided on said locking ramp means for retaining said latch
ramp surface adjacent said locking ramp means when said latch ramp surface engages
said locking ramp means on rotation of said coupling members relative to one another
about said axis of said connector assembly.
[0002] It is known to provide electrical cables with contacts which may be easily fitted
together in order to electrically connect the cables. An example of an especially
convenient cable contact is the "pin and socket" contact. The pin and socket contact
permits connection of two cables by simply sliding a pin on one cable into a socket
on the other. One type of widely used pin and socket contact, is the "twinax" contact
which is used to connect cables carrying two electrical wires surrounded by a common
jacket.
[0003] One such cable contact connector assembly is described in the US patent 4418946 issued
6th December 1983.
[0004] Because it is desirable to design such contacts to be as simple as possible, many
of the conventional pin and socket contact arrangements lack any sort of latching
mechanism. This is completely satisfactory for uses in which no strain is placed on
the cables in a direction which would cause the contacts to be pulled apart. However,
for many applications, some type of latching mechanism is required in order to prevent
the contacts from pulling apart. The most common means of providing this latching
mechanism is by trapping the contact inside an elaborate connector. The connector
then provides the mating and unmating mechanism as well as the latching mechanism.
[0005] While specially designed contacts are known which include a strain relief or latching
mechanism, there is a need for a strain relief or latching mechanism which may be
retrofitted onto conventional pin and socket contacts of the type which do not include
a latch.
[0006] Most conventional coupling mechanisms use asymmetrical "male" and "female" coupling
members. However, use of male and female coupling members doubles the number of different
parts required, and may cause problems due to the impossibility of coupling members
of the same sex.
[0007] In order to solve the problems inherent in using sexed couplers or connectors, hermaphroditic
or sexless coupling mechanisms are known. Nevertheless, hermaphroditic coupling mechanisms
which may be easily retrofitted onto conventional contacts have so far not been developed,
thus limiting application of the known hermaphroditic couplers.
[0008] It is an object of the invention to provide a releasable hermaphroditic coupling
mechanism which can be easily retrofitted onto a conventional cable contact arrangement
without modifying the contacts.
[0009] It is a further object of the invention to provide such a releasable hermaphroditic
coupling mechanism for a twinax cable contact.
[0010] It is a still further object of the invention to provide a releasable hermaphroditic
coupling mechanism which is easily coupled and released, and yet nevertheless provides
an especially secure coupling.
[0011] It is yet another object of the invention to provide a hermaphroditic coupling mechanism
which may be environmentally sealed against moisture penetration both at the rear
of the mechanism and at the interface between contacts.
[0012] Finally, it is an object of the invention to provide a method of releasably coupling
cables by using a hermaphroditic coupling mechanism.
[0013] These objects may be achieved by providing a coupling arrangement in accordance with
the invention which is characterised in that each of said coupling members has a central
bore in which are retaining means comprising an elastically deformable surface of
said bore which slopes radially inwards and ends in an elastically deformable detent
for retaining the coupling member on a respective part of the connector assembly,
said retaining means being elastically deformable to allow said detent to pass over
a radially outwardly projecting collar formed on said connector part during insertion
of the connector part into the coupling member so as to engage said collar after movement
of said detent over said collar to secure said coupling member to said connector part.
[0014] The coupling members are easily retrofitted onto respective contacts by a ramp and
detent mechanism provided in an inner bore of the coupler. The contact is inserted
into the bore until a collar on the contact passes over the detent and is retained
thereby.
[0015] An embodiment of the invention will now be described in detail, by way of example,
with reference to the drawings, in which:
[0016] Figure 1 is a cross-sectional view of a mated coupler and twinax contact pair according
to a preferred embodiment of the invention.
[0017] Figure 2 is an isometric view of one of the couplers of the pair shown in Figure
1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] Figures 1 and 2 illustrate a coupling mechanism for coupling two cable contacts and
locking them against disengagement according to a preferred embodiment of the invention.
Although the contacts illustrated are "twinax" contacts, one of which is a pin and
the other a socket, it will be appreciated that any of a large variety of cable contacts,
including power coaxial and triaxial contacts, may be used with the coupler mechanism
of the invention.
[0019] In the particular example shown, twinax contact pin 1 slides into twinax contact
socket 2 to effect an electrical connection between two twin axial cables (not shown).
The manner in which the contacts are connected to the cables is conventional and forms
no part of the invention.
[0020] Without some kind of latching mechanism, the pin 1 and socket 2 would be free to
disengage from each other because they do not include an internal latching mechanism,
other than the resilience of the tines 3 which form part of socket 2. The coupler
mechanism of the invention is intended to prevent such disengagement, and may be used
with any contact mechanism which might otherwise be disengageable under tension.
[0021] Figure 2 is a perspective view of coupling member 5, which is identical in structure
to coupling member 4. Coupling member 5 is generally cylindrical in shape, the axis
of the cylinder coinciding with principal axis 14 of the two contacts 1 and 2 as shown
in Figure 1.
[0022] The coupling member shown in Figure 2 includes two latch arms extending from a main
body 9 of the coupling member, and two locking ramp surfaces provided on a collar
18 which extends generally around main body 9. Because the coupling member has a 180
degree mirror symmetry, i.e., the coupler member will always appear identical when
rotated 180 degrees, only one of the latch arms and one of the locking arms ramps
is described in detail. Elements having primed reference numerals (e.g., latch arm
7′ and groove 24′) are identical to corresponding unprimed elements (e.g., latch arm
7 and groove 24).
[0023] Latch arm 7 includes a latch arm ramp surface 11 which is engageable with a complementary
ramp surface 21 on the corresponding mating coupling member 4 and which faces an interface
portion 20 of coupler member 5. Interface 20 is an annular surface surrounding the
bore 26 through which the contacts are inserted. Ramp surface 11 is provided on a
radially inward extending projection 13 at the distal end of latch arm 7. A corresponding
latch arm 6 including projection 12 and ramp surface 10 is provided on coupler member
4 and is engageable with ramp surface 21 on coupler member 5.
[0024] Interface surface 20 faces a corresponding interface surface 19 when the two coupling
members 4 and 5 are joined as shown in Figure 1. Although illustrated as being slightly
apart after coupling, it is also contemplated that the coupling members may contact
each other, or contact each other during coupling and then separate.
[0025] Locking ramp surface 21 faces away from interface surface 20 and is provided on collar
18, best shown in Figure 2. A detent 22 on each of the ramp surfaces provides the
means by which coupled coupler member 4 and 5 are coupled, as will be described in
more detail below.
[0026] Collar 18 includes a latch bypass groove 24 which permits corresponding projection
12 of latch arm 6 on coupler member 4 to be inserted through the collar. Groove 24
must be wide enough to permit passage of the corresponding latch arm 6 and ramp 10
on the mating coupling member 4, and must be positioned such that complementary locking
latches will not interfere with each other when the coupling members 4 and 5 are united.
[0027] It will be understood that collar 18 extends around main body 9 and therefore includes
a second, mirror symmetric, groove 24′, and that coupler member 4 is provided with
identical grooves provided in collar 17.
[0028] In order to provide for the greatest mechanical advantage during coupling, it is
preferred that bypass groove 24 be located adjacent a locking latch arm as shown.
However, this is not essential as long as it is possible for the corresponding latch
arm 6 on coupler 4 to bypass collar 18 and engage locking ramp surface 21 provided
on the collar.
[0029] Ramp surface 21 generally slopes away from the mating interface in the direction
in which the corresponding coupling member 4 will be turned during the latching process.
For the purpose of simplifying this discussion, the locking direction for member 5
shall be counter-clockwise as indicated by arrows 35, although a clockwise locking
direction could easily be obtained by locating bypass groove 24 adjacent the other
of the locking latches 7′and by sloping the ramp surface 11 in a direction opposite
the direction shown.
[0030] The leading edge of locking ramp surface 21 ends in detent 22, which is formed by
surface 23, a short portion of ramp surface 21 raised in the axial direction, away
from the interface surface 20 located adjacent to the clockwise edge of groove 24.
Detent 22 is designed so that latch arm ramp surface 10 on latch arm 6 of member 4
will pass over the detent and engage ramp surface 21 upon coupling, detent 22 preventing
backwards rotational movement of member 4 upon engagement. The operation of the coupling
mechanism will be described more fully below.
[0031] In order to prevent moisture and dust infiltration into the assembly upon coupling,
interface surfaces 19 and 20 between the coupling members 4 and 5 preferably each
includes a groove for retaining o-rings 38 and 27 which effect an environmental seal
between the coupled unit formed by members 4 and 5. It will of course be appreciated
that other environmental sealing arrangements will also occur to those skilled in
the art.
[0032] If used, o-rings 38 and 27 may provide resilience in order to bias the latch arm
ramp surfaces against respective locking ramp surfaces. Alternatively, the latch arms
or the detents may be formed of a plastically deformable material such that the material
deforms as the latching ramp surfaces ride over the detents during coupling, the restoring
force of the material causing the detents to regain their shape in order to retain
the latch arms in place.
[0033] In order to facilitate retrofitting onto the contacts, coupling members 4 and 5 preferably
also include a contact snap retention feature. A ramp and a detent are located on
the inner surface of bores 26 and 46 in each of members 4 and 5 through which the
contacts are separately inserted. Contacts 1 and 2 are provided in this embodiment
with annular collars 28 and 31. During separate insertion of the contacts into bore
26 and 46, the collars press against respective ramp surfaces 29 and 32, which plastically
deform until the collars pass detents 30 and 33, at which time the ramps and detents
are restored to their original positions, holding the collars in place against annular
shoulders 40 and 41.
[0034] It will of course be understood that the contacts may be retained within the coupling
members by any of a variety of suitable contact retention mechanisms, and also that
retention may be obtained without any additional means provided on the members, for
example by an interference fit.
[0035] Finally, in order to provide further environmental protection of the contacts, grooves
36 and 39 are provided in the main bodies 8 and 9 of each coupling member for holding
seals 34 and 37, preferably o-rings, between the respective contacts and bodies to
seal the rear of each coupling member.
[0036] The coupling mechanism of the preferred embodiment is operated as follows: Coupling
numbers 4 and 5 are first respectively secured on pin 1 and socket 2 by inserting
the respective contacts through bores 26 and 46 until collars 28 and 31 pass detents
30 and 33, which plastically deform as the collars pass the detents, after which the
time the ramps and detents are restored to their original position, holding the collars
in place against annular shoulders 40 and 41.
[0037] In the preferred embodiment, the respective coupling members must be inserted over
the cables or secured to their contacts before the cables are connected thereto. However,
by reversing the order of the ramps, detents and annular shoulders, those skilled
in the art will recognize that it would then be possible to slide the coupling member
over contact from the leading portion of the contact rather than from the cable side
of the contact, thus permitting the coupling member to be added after the contact
had already been secured to the cable.
[0038] Once the coupling members have been snap-locked onto the respective contacts, they
are coupled by initially aligning respective latch arms with respective grooves on
the complimentary locking members. The pin and socket are slid together as the aligned
latch arms are inserted through the grooves. The coupling members 4 and 5 are then
rotated in a counter-clockwise direction relative to each other in the preferred embodiment,
so that the latch arm ramp surfaces ride up over the groove curved surfaces, over
the detents, and onto the locking ramp surfaces, at which point the coupling members
are locked together preventing disengagement of the contacts.
[0039] Because of the illustrated position of the grooves, latching takes place over a rotation
of approximately 75°. By making the projection smaller, the amount of rotation necessary
to accomplish latching could be increased, while moving the grooves away from respective
latch arms would decrease the amount of rotation necessary to accomplish latching.
It will be appreciated that all of the above-mentioned variations are within the scope
of the invention.
[0040] Furthermore, it would be appreciated that the provisions of two latch arms and respective
locking ramps on each coupling member, while desirable, is not essential. The invention
would work with a single latch arm or with, for example, three latch arms and locking
ramps having a 120 degree symmetry.
[0041] In order to unlatch the coupling mechanism of the preferred embodiment, it is simply
necessary to reverse the direction of rotation until the respective locking projections
are aligned with respective grooves, at which time the coupling members can be pulled
apart by pulling the locking projections through the respective grooves, thereby also
disengaging the pin contact from the socket contact. Thus, unlatching and release
of the coupling arrangement is as easily accomplished as is latching.
[0042] Although a specific embodiment of the invention has been described in detail above,
it is to be understood that no part of this description should be interpreted as a
limitation. Those skilled in the art will appreciate that the invention is capable
of numerous modifications, alterations, and substitutions of parts without departing
from the scope of the invention, which is defined solely by the appended claims.
