FLOATING CONNECTOR ASSEMBLY

Abstract: A connector assembly has first and second connectors (4, 6) that are floatably mountable with respect to frames (20, 80) of devices to enable absorption of positional tolerances during coupling. One of the connectors (6) has guide projections (58) formed by orthogonal tapered walls (64, 66) received within in a shoulder (68) of the mating connector. The projections (58) reduce the cross-sectional surface area required for guiding the connectors together. The connector (6) is releasable from its support frame (80) once the connectors are fully coupled, by camming of the latch (78) during coupling. Large positional tolerances in the mating direction are thus absorbed.

Description: FLOATING CONNECTOR ASSEMBLY This invention relates to an electrical connector assembly comprising a first connector and a second connector matable therewith, the assembly floatably mounted with respect to a device such as a panel to enable adjustment of positional tolerances during coupling. European Patent 371835, and German Patent DE 3903839, disclose connectors floatably mountable to a panel or support in order to adjust for tolerances in the relative position between connectors to be coupled. In DE 3903839, the connector compensates for angular misalignment in addition to translational misalignment. Adjustment for misalignment is typically required when the connectors are mounted on devices that are assembled together, whereby connector coupling occurs automatically. The devices may be relatively large with respect to the connectors, an example of a potential application being the assembly of automobile body or component parts, such as an automobile chassis to an automobile body. Assembly of such devices would require particularly large absorption of positional tolerances. In the prior art, it is typical to have a connector with a funnel shaped entry at the mating face for guiding the mating connector. The funnel shaped mating face increases the cross-sectional size of the connector. The larger the required tolerance adjustment, the larger the cross-section. This is sometimes a disadvantage, for example where connectors are positioned through cut-outs of a panel or support structure. Large cut-outs may structurally weaken the device. It would therefore by desirable to provide connectors with compact cross- sectional areas . It would also be advantageous in certain applications to improve the adjustment for mispositioning in all six degrees of freedom (translation and rotation with respect to the 3 axes X, Y, Z of a cartesian system) . When assembling large devices, mispositioning in the direction of coupling may be quite large. Prior art connector assemblies, such as shown in DE 3903839 do not have the ability to adjust for large tolerances in the mating direction. It would be desirable in certain applications to have large tolerance absorption in the connector mating direction. It is an object of this invention to provide a connector assembly that enables adjustment to large positional tolerances in a reliable manner. It would be advantageous to provide a connector assembly that allows large adjustment in the direction of coupling of the connectors, with respect to devices to which connectors of the assembly are mounted. It would be advantageous to enable large positional tolerance adjustment in all 6 degrees of freedom in certain applications. It would be advantageous to provide a connector assembly that is compact, particularly with respect to a cross-section taken perpendicularly to the connector mating direction. Objects of this invention have been achieved by providing the connector assembly according to claim 14. Disclosed herein is a connector assembly comprising a first connector and a second connector matable therewith in a mating direction, each of the connectors mountable to a support structure whereby at least one of the connectors is floatably mountable on its support structure such that the connector is movable in a plane orthogonal to the mating direction, the connectors being provided with complementary guide means for correctly guiding and locating the connectors during mating, wherein the guide members comprise at least one projection extending in a mating direction from a mating face of one of the connectors for engagement with wall portions of the other connector, the wall portions extending in a substantially planar manner from a mating face of the other connector in the mating direction, the at least one projection being provided with tapered guide surfaces sufficiently large to absorb substantially the whole tolerance requirement of the connector assembly. The projection may comprise a pair of thin walls arranged substantially orthogonally with respect to each other, each of the walls being provided with a tapered guide surface along an edge of the walls facing the mating connector. A pair of projections may be provided, each proximate opposed longitudinal ends of the connector. Advantageously therefore, a connector with a compact cross-sectional area is provided that is nevertheless able to adjust to relatively large positional tolerances. Objects of this invention have been achieved by providing a connector assembly according to claim 1. Disclosed herein is a connector assembly comprising a first connector and second connector matable therewith, the second connector being securely mountable on a support via releasable latch members thereof, wherein the latch members and first connector have portions that cooperate during mating of the connectors for biasing the latch members such that the second connector is released from the support and floatable with respect to the support in the mating direction. The latch members may be provided with further latching shoulders that engage complementary latching shoulders of the first connector once the connectors are fully coupled and the second connector released from the support in order to secure the connectors together. The latch members further comprise camming surfaces engageable with a member fixed to the support during uncoupling of the connectors, engagement of the camming surface with the fixed member causing the latch member to disengage the first connector latching shoulder during uncoupling to enable automatic uncoupling of the connectors. The first connector may be provided floatably mountable to a device in a plane orthogonal to the mating direction, the connector also being rotatably floatable for angular misalignment. Advantageously therefore, the connector assembly can adjust to large tolerances in the mating direction. Further advantageously, automatic uncoupling is provided during separation of devices to which the connectors are mounted. Also advantageous is the ability of the connector assembly to adjust for mispositioning in all six degrees of freedom, to a large extent and in a reliable manner. Further advantageous aspects of this invention are set forth in the claims, or will be apparent from the following description and drawings.

Referring to figures 1-5, an electrical connector assembly 2 comprises a first connector 4 and a second connector 6 matable therewith. Each of the connectors are provided with electrical terminals positioned in terminal receiving cavities thereof, the terminals and cavities not shown in order to enhance clarity, it being understood that the cavities and terminals may be of any conventional sort. In the first connector 4, the terminals are received in a housing 8 that extends in a mating direction Z from a terminal receiving face 10 to a mating face 12 (see figure 6a) facing the mating second connector 6. The second connector 6 also comprises a housing 14 extending from a terminal receiving face 16 (see figure 6a) to a mating face 18. The first connector 4 is mountable to a support of a first device, and the second connector 6 is mountable to a support of a second device for assembly to the first device the devices and supports are not shown. Referring mainly to figures 2-5, the first connector 4 further comprises a fixed frame 20 mountable in a fixed manner to the device with screws or latches or other conventional fixing means (not shown) . The frame has a central opening 22 within which is movably mounted a movable frame 24 having a pair of side walls 25 arranged parallel and spaced a part, and held together at ends by end walls 26. The walls 25,26 of the movable frame 24 thus form an opening 28 within which is movably received the connector housing 8. Side faces 30 and end face 32 of the connector housing are separated from the movable frame walls by a gap allowing tolerance adjustments therebetween. Likewise, the walls 25, 26 of the movable frame 24 are separated from walls 21,23 of the fixed frame 20 that forms the opening 22, by a gap to allow movement therebetween. Side walls 30 of the housing 8 are provided with lugs or projections 34 that engage in oblong recesses 36 that extend along opposed side walls 25 of the movable frame 24. The housing 8 is thus slidable in a direction X between end walls 26. The lugs 34 are provided with opposed arcuate surfaces 38 that enable the housing to rotate about a Y axis orthogonal to the X axis. The rotation about the Y axis is indicated in figure 4 by the curved arrow 40, and the translational movement along the X axis is shown by the arrow 42. The frame 24 is provided with lugs or projections 44 extending outwardly from opposed end walls 26 and received in oblong recesses 46 in end walls 23 of the fixed frame 20. The movable frame 24 can thus slide in the Y direction with respect to the fixed frame 20, and also rotate about the X axis whereby the lugs 44 are also provided with opposed arcuate surfaces 48. As shown in figure 5, rotation of the connector housing 8 about the X axis is shown by the arrow 50, and translation in Y direction is illustrated by the arrow 52. Engagement of the movable frame lugs 34,44 in the respective recesses 36, 46 of the fixed frame also allows a certain rotation of the connector 8 about the Z axis. The end walls 26 of the movable frame 24 are provided with arcuate outer surfaces 53 to enable rotation about the Z axis of the frame 24 in the fixed frame 20. The rotation about the Z axis is indicated in figure 3 by the arrow 54. Referring to figures 1, 3, and 6a, the second connector 6 is provide with guide projections 58 proximate opposed ends 33 of the housing 14. The guide projections 58 extend in the mating direction Z from the mating face 18 towards the mating connector 4 and are positioned between terminals of the connector. The guide projections 58 are tapered, the pointed end 59 of the taper 60 remote from the mating face 18. The pointed end or tip 59 is substantially centrally positioned between opposed side walls 62 of the housing 14. The projections 58 each comprise a first thin wall 64 substantially parallel to a plane formed by the Y and Z axes, and a second thin wall 66 orthogonal to the first wall 64 (extending substantially parallel to a plane formed by the X and Z axes) . Although the walls (64, 66) are shown joined together in figures 1 and 3, they could also be separate as shown in figure la where the first thin wall provided proximate the end wall 33 and the orthogonal second thin wall substantially centrally between opposed end walls. The taper 60 is provided on upper guide edges 62 of the walls 64, 66, such that the walls extend substantially from the housing side and end walls 62,33 respectively and culminate in the tip 59. The tapered projections 58 are therefore able to reposition the mating connectors 6,4 in the Y direction by a distance substantially half the width of the connector between side walls 62. The tolerance adjustment in the X direction depends on the length of the taper 60 of the second orthogonal walls 66 which extend from the end wall 32 to the first guide walls 64. In the present embodiment, the taper 60 of the second wall 66 is substantially the same as the tapers 60 provided on the first wall 64 such that the tolerance adjustment in the X and Y direction is substantially the same. The projections co-operate with guide walls 68 of the first connector housing 8, the guide walls 68 extending beyond the mating face 12 to a mating end 70 thereby forming a shroud receiving the second connector housing 14 therein. The guide walls 68 extend substantially in alignment with the connector side walls 62 and end walls 32 respectively such that the cross-sectional area of the connector remains compact. In other words, a guide funnel which enlargens the connector cross-sectional area (taken perpendicular to the mating direction Z) is avoided. Tolerance adjustment between the mating connectors 4,6 thus occurs by engagement of the tapered guide projections 58 with the shroud or guide walls 68, the guide projections 58 subsequently being received within corresponding projection receiving cavities 72 (see figure 3) of the first connector housing 8. When viewing towards the mating face 12 of the first connector housing, the projection receiving cavities 72 have a T- shape corresponding to the T-shape of the projections 58. The latter construction ensures that minimum usage of cross-sectional area is taken up by the guide projections. For example, when viewing figure 3, terminal receiving cavities 74 for receiving corresponding terminals may be provided in corner portions 75 of the mating face formed by the T-shaped cavity 72. In other words, the projection 58 is provided among the terminals rather than externally of the mating face. A compact cross-sectional dimension of the connectors is thus achieved, which correspondingly reduces the size of a cut-out in a panel or support member of a device on which the first connector is mounted. The provision of thin orthogonal walls 64,66 also reduces the cross-sectional surface area needed for the guide members to a minimum. The projection 58 may also have separated walls 64, 66 positioned at different locations (i.e. the walls 64, 66 do not have to be joined together in a "T"-shape) , with corresponding cavities in the mating connector housing 8. Referring to the figures 6a-6j, and the corresponding detailed figures 7a-7j, coupling of the connectors and floatability of the connectors in the Z direction will now be explained. Referring first to figures 6a, 7a, the second connector 6 comprises a first latch member 78 positioned along one of the end walls 33 of the housing 14, and a second latch member 79 positioned along one of the side walls 14. It would also be possible to provide a pair of each latch member for positioning on the pair of opposed end and side walls respectively . The latch members 78, 79 are securely attached to the housing 14, and in this embodiment the latch members are integrally moulded from plastic with the housing 14. As also shown in figure 2 , and 6a, the latch member 78,79 are for latching the connector housing 14 to a frame 80 of the second connector 6. The frame 80 comprises side walls 82 substantially parallel and opposed to each other and joined by end walls 83 to form an opening 84 through which the connector housing 14 is received. The frame 80 is for fixing to a support member of a second device by fixing means (not shown) such as screws or latches or other conventional means. The side latches 79 (see figure 2) comprise latching shoulders 85 that engage a lower edge (see figure 6a) 86 of the frame 80 for limiting the upward movement of the connector 6 towards the mating connector. As best seen in figure 7a, the first latch member 78 comprises a frame latching shoulder 88 proximate an end 90 of the latch remote from the mating connector 4. The frame latching shoulder 88 engages a complementary latching shoulder 92 positioned in a recess on the end wall 83 of the frame 80 for limiting the downward movement of the housing 14 with respect to the frame 80 in a direction opposite to the mating first connector 4. The latch member 78 is elastically pivotally attached to the housing 14 substantially about a pivot axis 94 positioned between the remote end 90 and an end 96 facing the mating connector 4 (the near end) . An inwardly tapered camming surface 95 is provided proximate the near end 96 for engaging the mating end 70 of the first connector 4, which is also provided with a inwardly tapered guide surface 93 for co-operating with the latch camming surface 95. As best seen in figures 7b and 7c, coupling together of the connectors causes the mating end 70 to bias apart the near end 96 of the latch 78, which causes inward biasing of the remote end 90. The frame latching shoulder 88 thus disengages from the corresponding latching shoulder 92 of the frame end wall 83 such that the connector assembly is freed in the mating direction Z. The connector assembly descends in the direction Z until engagement of an intermediate shoulder 99 of the latch member 78 with an upper shoulder 91 of the frame end wall 83. The connector assembly is thus blocked from further movement in the mating direction Z such that the first connector 4 can be fully coupled towards the second connector 6 until their respective mating faces 12, 18 are substantially in abutment as shown in figures 6d and 6e. In the fully coupled position, a connector latching shoulder 97 engages a complementary latching shoulder 89 of the first connector thereby securely latching the connectors together. Engagement of the latching shoulders 97, 89 allows the latch 78 to resiliently bias into its natural position such that the intermediate shoulder 99 of the latch disengages the upper shoulder 91 of the support frame end wall 83, thereby allowing further movement in the mating direction Z of the mated connector assembly. Large positional tolerances in the mating direction Z can thus be absorbed. The intermediate shoulder 99 ensures that the connectors are fully coupled before the latch member 78 fully releases from the support frame 80. De-coupling of the connectors will now be explained referring to figures 6g-6j and corresponding figures 7g- j . When separating the first connector 4 from the second connector 6, an outwardly tapered release camming surface 98 proximate the remote end 90 of the latch 78 engages a corresponding release camming surface 100 of the support end wall 83 thereby inwardly pivoting the remote end 90 as shown in figure 7h. Pivoting of the latch member 78 releases the connector latching shoulders 97, 89 as best seen in figure 7i thereby allowing separation of the connectors as shown in figure 7j . The second connector housing 14 is biased back to its initial position where the frame latching shoulder 88 engages with the corresponding latching shoulder 92. The return to the initial position is assisted by the resilient force of the latch member 78 acting on the oblique co-operating camming surfaces 98, 100. As best seen in figure 7g, the camming surface 98 of the latch remote end 90 is not fully biased inwardly when passing the projection 101 on which the support wall latching shoulder 92 is provided, such that the connectors are only unlatched once the frame latching shoulder 88 passes the latching shoulder 92. Referring now to figures 8-12, another embodiment of this invention will be described. The embodiment of figures 8-12 is floatable in the mating direction (Z) according to a similar principals of function as the previously described embodiment. Elements of the assembly 2' that have the same or similar function to previously described elements will be given the same number but with a prime ( Λ ). The embodiment of figures 8-12 is not provided with any particular means for absorbing tolerances in the X and Y directions as in the previously described embodiment, however similar tolerance adjustment means for absorbing misalignment in the X and Y directions as described in the previous embodiment could be incorporated into the assembly of figures 8-12 if desired. The connector assembly 2' comprises a first connector 4' and a second connector 6' . The first connector 4' comprises an insulative housing 8' extending from a terminal receiving end 10' to a mating end 12' and receiving a plurality of terminals 11' that are matable with complementary terminals of the second connector 6' . The second connector 6' comprises an insulative housing 14' extending between a terminal receiving face 16' and a mating face 18' that faces the mating face 12' of the first connector 4' just prior to coupling as best seen in figure 8 or 9. The housing 14' may be made of one or more parts assembled together, and comprise a plurality of terminal receiving cavities 74' for receiving terminals therein. The terminals may be pre-mounted to a housing module 15' that is inserted into the main housing 14' . The first connector 4' is mountable to a first device (not shown) which may be in the form of a panel or other structure, and similarly the second connector 6' is mountable to a second device which is to be assembled to the first device. An application may for example be the assembly of a steering wheel of an automobile to a steering column, or various body parts of an automobile to other body parts, where electrical interconnection is required. Such devices may be many times larger than the connectors themselves, and it would be advantageous to provide large absorption in relative positioning, particularly in the mating or assembly directions of the devices in order to provide reliable automated assembly including electrical interconnection. The first connector 4' may be attached to the first device via a frame similar to that already described for the previous embodiment. The second connector 6' is in this embodiment mountable to a frame 80' that is mountable to the second device (not shown) by any conventional means, or may be mounted floatably in the X and Y directions with respect to the second device by any conventional means. The frame 80' comprises opposed side walls 82' and opposed end walls 83' that form an approximately rectangular member with an opening or cavity 84' for receiving the second connector housing 14' therein. The opening or cavity 84' co-operates with the second connector housing outer periphery such that the housing is slideably movable in the mating direction (Z) after the connectors 4', 6' are fully coupled. The second connector 6' is provided with one or more resilient releasable latch members 78' that are formed on the frame 80' . It may be noted that in the embodiment of figures 1- 7, the resilient latch 78 was provided on the second connector housing 14 whereas in the embodiment of figures 8-12, the resilient releasable latch 78' is provided on the frame 80' . As best seen in figures 8 and 10, the latch 78' is in the form of a resilient beam integrally moulded with the frame 80' and extending from an attachment end 94' proximate the far end 86' of the frame (with respect to the mating end) and extending therefrom to a free end 96' where frame latching shoulders 88' are provided. The frame latching shoulders 88' are engageable against latching shoulders 92' of the second connector housing 14' to retain the second connector 6' to the frame 80' in the mating direction (Z) when the connectors 4', 6' are uncoupled. Co-operation of the latching shoulders 88', 92' is best seen in figures 10a or 10b, whereby the second connector housing 14' is prevented from movement in the mating direction (Z) towards the remote end 86' of the frame 80' . In order to prevent the connector housing 14' from removal from the frame 80' in the opposite direction, the frame and housing are provided with complementary latches 105, 107, which as best seen in figure 11a, 10a, or llb-lld, have complementary locking shoulders 108, 109 that prevent removal of the housing 14' towards the mating end 91' of the frame 80' . The latches 105, 107 however allow movement of the housing 14' towards the remote end 86' of the frame 80' as best seen in figure lid. The resilient latches 78' are further provided with camming surfaces 95' that are engaged by complementary camming or guide surfaces 93' of the first connector 4' during coupling. As best seen in figure 10c, once the connectors 4', 6' are coupled, the first connector camming surface 93' rides over the latch camming surface 95' and biases the resilient latch 78' out of engagement with the complementary latching shoulders 92' of the second connector housing 14' . At this moment, the first and second connector housings 8', 14' are latched together and free to move in the mating direction (Z) towards the remote end 86' of the frame 80' . The latter is best seen by looking at figures lOd and lid. The second connector 6' is latched to the first connector 4' by provision of complementary latch protrusion and locking recesses 97', 89' on the second and first connector housings 14', 8' respectively (or the inverse) . The protrusions and recesses are provided with tapered locking shoulders 97', 89' that fully engage simultaneously with the release of the housing and frame latching shoulders 92', 88' respectively at the position shown in figures 10c and lie. The functioning of this embodiment thus differs slightly from the previous embodiment, in that the latching of the connector housings 8', 14' occurs simultaneously with the release of the second connector housing 14' from the frame 80' whereas in the previous embodiment latching of the connectors 4, 6 occurred prior to release of the fully coupled connectors from the frame 80. In the present embodiment, the connector latching recesses or shoulders 89' are provided on substantially planar flexible extensions 110 projecting from the connector housing mating face 12' to provide a particularly compact yet effective latching arrangement. The extensions 110 are received in complementary slots 112 within the second connector housing 14', the latching protrusions 97' protruding into the slot 112 from side walls of the second connector housing 14' . When uncoupling, the second connector housing 14' and/or release camming surfaces 100' of the first connector housing engage the complementary release camming surface 98' of the resilient latch 78' for biasing the latch during passage of the second connector latching surfaces 92' therepast, until the latching shoulders 92' engage with the resilient latch locking shoulders 88', which defines the initial latching positions shown in figures 10b and lib. The connector housings 8', 14' can then be unlatched to the positions shown in figures 10a and 11a whereby the second connector housing 14' is retained to the frame 80' by the retention shoulders 108, 109. The advantages of large positioning adjustment in the mating direction is thus provided in a particularly compact and reliable arrangement, that allows automatic interconnection of electrical connectors during assembly and disassembly of components.
