    摘要： An environmental protector for electronics devices in outside terminal boxes. The protector has a laminate wall which provides a moisture barrier, penetration resistant surface and EMI shield. The protector may be flexible or substantially rigid and is in the form of an open-ended container for receiving an electronics device. The container is sealed at the open end around a connector unit of the device with outgoing terminals accessible for connection purposes. The device may be potted within the container. Conveniently, the EMI shield is connected to ground by a ground element in the connector unit.

    摘要： The invention provides an articulated latch for use with the faceplate of a printed circuit board (PCB) adapted to be inserted into and removed from its functional location on a mounting frame. The latch comprises an actuating member pivotally secured to a latching member adapted to be pivotally attached to the faceplate of a PCB. The actuating and latching members have an interface mechanism comprised of cooperating tab, slots, and wells for allowing the actuating member to lock at at least two positions into the latching member. With the PCB positioned in its functional location, the actuating member of the latch may be stored in an approximately horizontal position.

    摘要： Electronic unit in which a printed circuit board is located within a housing which includes a heat sink. The board is normally urged out of heat conductive relationship with the heat sink. As temperature increases the circuit board and heat sink are caused to move relatively so as to bring the board into heat conductive relationship with the heat sink so as to remove heat from the board. As temperature decreases the board and heat sink are again moved out of heat conductive relationship. Preferably a heat conduction element is provided to conduct heat from the board. This comprises at least one compressible member, e.g. compressible cellular material, which is progressively compressed as temperature increases. Preferably the heat conductive efficiency of the compressible member increases as compression increases.
