  • Patent number: 6261122
    Abstract: A fixture lowering assembly for lowering fixtures, such as security and surveillance cameras, that require connection and disconnection of multiple complex electrical contacts is disclosed. The assembly includes a fixed housing that is mounted above ground level and a movable housing containing the fixture and being capable of being lowered to the ground level. A connect unit connects the fixed and movable housings and includes a latching assembly and first and second electrical connectors. The first and second connectors are each mounted on a pair of guide rods that extend through a pair of springs so that the first and second connectors freely float to facilitate connection and disconnection. The electrical connectors also include mounting bodies capable of receiving a variety of different electrical contact plates depending upon the type of fixture used with the lowering assembly. This construction of the contact plates also provides a moisture proof seal about the pins and sockets.
