A positive release bracket (16) for an object such as an electrical connector part (12) includes first and second semicylindrical shells (18,20) which are releasably held together by plates (36,38). On a separation force applied to the connector exceeding some predetermined maximum, one or both plates (36,38) are withdrawn from engagement with the shells (18,20).

Secondary release apparatus

The present invention is a separation nut for fastening and releasing a threaded bolt under remote or manual controls. The preferred embodiment of the present invention separation nut includes a housing, a base, a ramp which is fitted into the base, and a three-piece segmented threaded nut placed on top of the ramp and enclosed by a three-piece segmented spool, which is in turn bounded by a restraining wire. The three-piece segmented threaded nut and the three-piece segmented spool are held in place by a spring biased plunger. Anti-rotation pins are employed for preventing rotation of the segmented nut. A release pin is provided for inhibiting the restraining wire from releasing the segmented spool. The release pin is connected to a flexible shaft.

Separation nut with a restraining wire

The invention is directed to a multi-contact electrical connector, especially a flat pack connector. The housings for plug and receptacle are X-ray absorbent metal to substantially decrease X-ray penetration. The receptacle face has perforations in the housing metal of dimensions to function as an EMI Grid to shield against RFI entry through the wave guide perforations. Also the perforations are long enough to substantially shield the sockets from X-rays striking the perforations at an angle. The plug and receptacle are locked in mated relation by collet fingertips which close to a ball shape for entry and exit from a receptacle recess, and open wide to a diameter larger than the entry/exit opening in the recess to lock the plug and receptacle in the mated position. A spring loaded plunger rod maintains the locked position. The tug of a lanyard releases the spring load and the fingertips close, are pulled out of the recess by another spring, unlocking the connector and also separating the receptacle from the plug.
