Abstract

A connector cover (10) fits over a connector (20) to define an exit (11a) for a wire (W). The wire is guided in a groove (13,14a) and retained by a latchable closure (31,50,130,240,326). An external force applied to the wire W does not separate the wire from the groove; several embodiments are disclosed.

Claims

1. A connector cover for attachment to an electrical connector having a protruding wire, the cover comprising a main body having an opening for forming a wire outlet with the connector, and side walls forming a wire supporting groove having an open side, at least one of said side walls being resilient for gripping and holding the wire in a pre-determined direction when inserted within said groove, said cover further including a latchable closure for closing the open side of said groove, said closure having a gripping structure for engaging each said resilient side wall to prevent said side walls from moving apart and to retain the wire within said groove.

2. A connector cover according to claim 1 wherein the latching direction of said closure is different from the insertion direction of said wire in said groove.

3. A connector cover according to claim 1 wherein said closure comprises mutually engageable clamps mounted on either side of said groove, said clamps being pivotable towards one another to close said groove.

4. A connector cover according to claim 3 wherein said clamps each have oppositely directed first and second arms, said first arms being directed towards one another to partially close said groove in the open condition of said closure, and being pivotable apart in the closed condition of said closure, and said second arms being apart in the open condition of said closure, and being pivotable towards one another to close said groove in the closed condition of said closure, the clamps being pivotable from one condition to the other by insertion of a wire into said groove.

5. A connector cover according to claim 1 wherein said closure comprises opposite clamp members having sequential mutually engageable latch members whereby the degree of engagement of the clamp members can be selected.

6. A connector cover according to claim 1 wherein said closure includes opposite cam formations to urge opposite walls of said groove together, thereby to grip a peripheral surface of a wire.

7. A connector cover according to claim 6 wherein said closure includes a latch member independent of a cam formation.

8. A connector cover according to claim 1 and comprising a one piece plastics moulding.

9. A connector cover for attachment to an electrical connector having a protruding wire, said cover comprising a main body including an opening for forming a wire outlet with the connector and a wire supporting portion, and wire securing closures for retaining the wire within said cover, each said closure being pivotally secured to said main body such that said closures are capable of pivoting to an open wire receiving position and to a closed wire retaining position, said closures each including a wire engaging wall for gripping and holding the wire in a pre-determined position when said closures are in said closed position, at least one protrusion for engaging a protrusion of an opposing one of said closures to enclose the wire, and a stopping member to prevent said wire engaging walls of said closures from moving apart and thereby retain the wire within said connector cover.

10. The connector cover according to claim 9 wherein said main body portion includes side walls each extending along a portion of one of said closures, and wherein each said closure is positioned between said main body side walls.

11. The connector cover according to claim 10 wherein said main body side walls each include a recess for receiving said stopping member of a portion of a respective one of said closures for securing said closures in the closed position.

12. The connector cover according to claim 9 wherein said wire supporting portion includes an arc-shaped seat for supporting the wire when inserted within said cover.

13. The connector cover according to claim 9 wherein said protrusions each include a plurality of said stopping members formed thereon for engaging the stopping members of the opposing closure and locking said closures together.

14. The connector cover according to claim 13 wherein said stopping members include a plurality of saw-tooth shaped members.

15. The connector cover according to claim 14 wherein said securing member includes a protrusion extending along the length of said groove.

16. A connector cover for attachment to an electrical connector having a protruding wire, said connector cover comprising a main body including an opening for forming a wire outlet with the connector, side walls forming a wire supporting groove with an open side, at least one of said side walls being resilient for gripping and holding the wire in a pre-determined direction when inserted in the groove, and a securing member positioned opposite said open side of said groove with an abutting surface facing said groove, said connector cover also including a latchable closure pivotally secured to said main body and overlapping said open side of said groove, said latchable closure abutting said abutting surface of said securing member to prevent said latchable closure from shifting away from said groove when closed to thereby retain the wire in said groove.

17. The connector cover according to claim 16 wherein said latchable closure also includes at least one locking projection for engaging said main body to prevent said closure from pivoting away from said groove.

18. The cover according to claim 17 wherein said side wall includes a step for engaging with said protrusion to prevent the latchable closure from shifting away from said groove and to prevent the wire from moving out of said groove.
