Abstract
Description
- This invention relates to a rack and pinion type of locking means for the coupling of complementary connectors.
- A rack and pinion mechanism for coupling mating connectors together is known from German Utility Model G 8714016 and shown in Figure 1, whereby a receptacle connector assembly 4' comprises a
gear 10' pivotable about an axis and attached to a lever arm 14'; and a pinheader connector assembly 3' comprises a rack 11' along a wall of a cavity 13' receiving the receptacle connector 4'. Mating of theconnectors 2' and 3' is effectuated by simply inserting the receptacle connector into the cavity of the pinheaded connector whereby engagement of the rack 11' andpinion 10' causes the gear arm 14' to rotate and allow full insertion of the receptacle connector into the male housing cavity. Uncoupling of themating connectors 2', 3' is effectuated by simply rotating the lever 14' in the opposite sense. - In order to ensure locking of the mated connectors, the lever can be latched in it's final position by some resilient latching means. In the open position however, the
lever arm 20 should be held in a fixed position such that coupling of the connectors is rapidly done by merely inserting the connectors and snapping them together. The gear lever arm of the Utility Model engages the receptacle housing with a dimple thereon for resiliently holding the lever in the fully open position, the lever being rotatable into the closed position by simply exerting sufficient torque to the gear (which occurs when firmly pressing the mating connectors together). - One of the problems associated with the prior art open-position retention means, is that after a few connections and disconnections, the dimple may wear and be less effective in holding the gear lever open. Furthermore, as the retention means must be releasable with a reasonable force, the gear lever may also be accidently rotated from the open position, the operator then requiring to first open the lever prior to mating.
- It is therefore an object of this invention to provide a rack and pinion coupling means for mating connectors that is reliable, reduces handling costs and is cost-effective to manufacture.
- It is a further object of this invention to provide a rack and pinion coupling means for mating connectors that allows reliable and rapid coupling of the mating parts whilst requiring low coupling forces.
- The objects of this invention have been achieved by providing a first connector housing having a gear member thereon interengageable with a pinion member of a mating second connector housing, whereby the gear member comprises a lever arm fixed in the open position by a resilient latching member of the first housing, the latching member cooperable with the second connector housing during coupling between the first and second connector housings to release the engagement of the latching member and gear lever arm thereby allowing full coupling of the first and second connector assemblies.
- The preferred embodiment of this invention will now be described in detail with reference to the figures, whereby;
- Figure 1 is a side view of mating connector assemblies of the prior art;
- Figure 2 is a side view of part of a connector assembly comprising a gear member according to the preferred embodiment of this invention;
- Figures 3, 4 and 5 are cross-sectional views through line 3-3 of Figure 2 but including a second connector assembly matable with the first, showing, respectively, different steps during coupling therebetween; and
- Figure 6 is an isometric view of part of the connector housing without the gear member showing more clearly the gear retention member.
- Referring first to Figure 2, a
receptacle connector assembly 3 comprising ahousing 4 having amain housing 6 for receiving electrical terminals therein, and agear member 8 comprising apinion 10 withgear teeth 12, and alever arm 14. Thegear member 8 is pivotly attached to anaxis 16 of thehousing 4. The terminals mountable in themain housing section 6 project towards amating face 18 thereof, theconnector assembly 3 being matable to a complementary connector assembly 2 (see Figure 3) similar to the connector assembly 2' of the prior art. The mating connector assembly would thus comprise a rack similar to the rack 6' for engagement with thegear teeth 12 of thepinion 10 during mating and unmating of the connector assemblies. Similarly to the prior art shown in Figure 1, the connector housing 4' would be inserted into a cavity of the complementary connector assembly whereby thepinion 10 and rack would engage causing thegear member 8 to pivot until the fully mated position indicated by thegear lever member 8 shown in dotted lines. - Referring to Figures 1-6, the
connector housing 4 further comprises aresilient latching member 20 attached to themain housing section 6 proximate themating face 18 and extending rearwardly therefrom to afree end 22. Referring to Figures 2 and 3, theresilient retention arm 20 is shown comprising, proximate thefree end 22, aretention shoulder 24 engageable against aretention shoulder 26 of thelever arm 14 when in the fully opened position, and atapered portion 23 for engaging the lever arm during opening thereby biasing the retention arm prior to locking engagement therewith. Intermediate thefree end 22 and attachedend 21, theretention arm 20 comprises acamming portion 28 projecting outwardly therefrom and engageable with awall 30 of the complementary connector housing for biasing of theresilient retention arm 20 out of locking engagement with the leverarm retention shoulder 26 as can be seen in Figure 4. - Figure 4 shows initial insertion of the
connector housing 4 into acavity 32 of acomplementary connector housing 34. During this initial insertion, theretention arms 20 are resiliently biased and release thelever arm 14 such that when thegear teeth 12 engage the rack of the complementary connector, thegear member 8 is free to rotate and allow full insertion of theconnector housing 4 into thecavity 32 as shown in Figure 5. Camming of theresilient retention arms 20 during mating, thus allows a low mating force between thecomplementary connector assemblies - Advantageously therefore, the gear member coupling means is securely and reliably maintained in the open position ready for coupling, and automatically released during the coupling without significantly increasing the mating forces required.
