Abstract

The processof separating two mated multi-pin connectorsoften results in the breakageof connector pins. This breakage typically occurs when uneven separating forces are applied to opposite sides of the connectors. These uneven forces cause the connectors to rock from side to side during separation, which results in pin breakage.

CONNECTOR SEPARATION MECHANISM

by Kenneth E. Cook

   The processof separating two mated multi-pin connectorsoften results in the breakageof connector pins. This breakage typically occurs when uneven separating forces are applied to opposite sides of the connectors. These uneven forces cause the connectors to rock from side to side during separation, which results in pin breakage.

   The connector assembly illustrated in the figure solves the pin breakage problem by causing equal separating forces to be applied to both sides of the connectors. Referring to the figure, a multi-pin connector 10 and threaded studs 12 and 14 are securely mounted in a recess 16 of housing 18. A mating multi-pin connector 20 has two guide holes 22 and 24 into which ejector pins 26 and 28 are respectively inserted. Hinges 30 and 32 are molded from a memory plastic and pivotally secured between cover plates 34 and 36 by screws 38 and 40. Hinges 30 and 32 are designed to flex slightly at thin cross sections 30a and 32a and include an irregular grip area 30b and 32b to prqvide a firm grip for the user's fingers. Wires 42 are soldered to the contacts of connector 16. An RF shielded rubber boot 44 surrounds the wires and is secured by an adhesive shielding compound. An adhesive may be injected through cover hole 34a to encapsulate the wiring.

   To separate the connectors, the thumb and forefinger of a hand are positioned over grips 30b and 32b and...
