Abstract

Electrical signals which are delivered to a printed circuit board assembly by cables must be plugged to connector pins. To prevent the cable from bending the connector pins, a cable retention shroud is plugged to the board pins. To ensure that the shroud does not come loose from the pins, retention clips are placed on the pin. The retention pins bite into the pin's palladium plating and score it to the base metal. Upon removal of the clip from the pin, further pin plating damage occurs. A described shroud retaining mechanism accomplishes both retention and removal without any damage to the pin plating. Seen in Fig. 1A is the prior method in which a shroud 1 is placed over connector pins 2. Fig. 1B illustrates a retention clip 3 in position over the pins 2.
