Abstract:
A multi-layered laminate structure forms a cover member that is capable of being sealed around the edges of a circuit board, around connector assemblies mounted on the circuit board, and against a mounting panel to which the circuit board is attached, to provide a sealed environment for electrical components mounted on the circuit board.
Abstract:
In one form, the invention is directed to the combination of: a plate; a first connector on the plate; a first circuit card assembly including a first circuit card and a second connector on the first circuit card which second connector is capable of coupling to the first connector; and a layer of sealing material on the plate and having a first opening therein to accept a part of the first circuit card assembly with the first and second connectors coupled. The layer of sealing material has a first cantilevered flap which has a first, relaxed state. The first cantilevered flap is deflected from the first state into a second state wherein the first cantilevered flap bears sealingly against a part of the first circuit card assembly with the first and second connectors coupled.
Abstract:
The body of a connector assembly is attached to the ground of a cable internally disposed within an enclosure. The connector body has a radial flange positioned on the outside surface of the enclosure and a nut, threaded onto a portion of the connector extending internally into the enclosure, is used to secure the connector body whereby a ground connection is established between the connector body and the enclosure. The enclosure panel on which the body is mounted is connected to ground. A mating connector is attachable to a portion of the connector body extending outwardly from the enclosure. In normal service, the slot in which the connector assembly is mounted is covered. However, when necessary to access the interior of the enclosure, the connector and attached cables can be removed from the enclosure panel by removing the cover, loosening the nut disposed on the internal end of the connector body, and sliding the assembled connector and cable pair out of the slot. The connector, and cable pair attached thereto, can be moved out of the way without separation or disconnection. This invention addresses the problem of requiring disconnection of mating cable pairs when performing maintenance, inspection, repair, or other activity on enclosed electronic components such as the base station of a mobile telephone system.
