Abstract: An installation coupler is disclosed for connecting a first cable (306) to a second cable (330) in and installation for supplying power to at least two workstations (322) via a free set of plug pin socket contacts (314) and via the second cable (330). The first cable (306) has a double female installation socket (300) with two sets of contacts (314) and the second cable (330) has a male installation plug (304) that can be plugged into at least one of the sets of contacts (314), with a predetermined orientation of the plug (304) relative to the set of contacts (314). The installation plug (304) includes a protruding stop (307) that partly obstructs the lower one of the sets of contacts (314) when the plug is incorrectly connected to the upper set, and that is clear of the contacts (314) when the plug (304) is correctly connected to the lower set. The protruding stop (307) thus prevents the simultaneous connection of the plugs (304) of more than one second cable (330), to the double female socket (300).

Abstract: An installation coupler is disclosed which comprises a male installation plug (10) and a female installation socket (130). The installation plug (10) comprises a casing (12) and a sleeve (24). Similarly, the installation socket (130) comprises a casing (132) and a sleeve (142). On assembly of the installation plug (10) to the installation socket (130), electrical plug pins, which are located within the sleeve (24), pass through openings (278, 280, 282) located in the front wall of the sleeve (142) and displace a shutter which allows the plug pins access to socket contacts, located within the sleeve (142), to allow electrical current to flow from the installation socket (130) to the installation plug (10). A barbed portion (200) of an elongate protrusion (198) cooperates with an opening (126) in the side wall of the sleeve (24) to prevent the installation coupler from being disconnected by merely pulling the installation plug (10) and the installation socket (130) apart.
