  • Installation couplers
    Patent number: 7001222
    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.
