  • Patent number: 5139430
    Abstract: A mechanical insertion/ejection lever device is provided for use in mounting a printed circuit board (PCB) into an electrical receptacle secured to a housing. Two lever members are pivotally mounted at or near the rear edge of a PCB, adjacent the corners. As the PCB is manually inserted into the housing unit, the lever members engage part of the housing. Rotation of the lever members causes a proportional linear motion of the PCB into engagement of the receptacle, overcoming frictional resistance of the electrical connectors. The lever members are rotatable through an arc of motion which corresponds to moving the PCB a linear distance sufficient to compensate for all accumulated manufacturing tolerances while fully seating the PCB within the receptacle. The lever members adjustably lock to retain the PCB in a fully seated position. The lever members also eject the PCB from the receptacle upon rotation in an opposite direction.

  • Patent number: 5110302
    Abstract: A latching system such as for matable first and second electrical connectors having matable pin and socket contact terminals comprises a pair of opposing latching arms each extending forwardly from a joint on opposing sides of the second electrical connector in cantilever fashion, to latchingly engage behind a pair of corresponding latching projections on opposing sides of the first electrical connector when the connectors are fully mated. The latching projections are high and abrupt and relatively sharp having steep forward and rearward surfaces generating substantial resistance to latching during mating. When the latching sections of the latching arms reach the sharp outer tips of the latching projections, the resistance to latching suddenly ceases and the latching sections immediately latch behind the respective projections without hanging up on top thereof, assuring full mating and providing a snap action which provides an audible signal.

  • Patent number: 4950174
    Abstract: A field separable ordnance stepover bracket connects abutting ordnance transfer fuse cables across the interstage junction of a multistage missile system using a plug and a receptacle. The plug receives a first set of ordnance transfer cables that terminate in percussion devices; and fits with the receptacle which receives a second set of similar ordnance transfer fuse cables. For maintenance, the plug is simply unplugged from the receptacle to allow access to the interior of the missile when the interstage junction is opened. For flight interstage separation, the fast burning ordnance transfer fuse cables ignite the percussion charges which are fixed in proximity to a linear shaped charge that circumscribes a flight separation junction. The percussion charges ignite the linear shaped charge which detonates to separate the stages of the missile.
