Processor Controlled Zero Insertion Force Connector

This article describes a solenoid-actuated, zero insertion force connec which can be opened and closed under processor control. Processor control can be used for the cleaning of contact surfaces, personalization of devices, and control of power distribution within a device.

Fig. 1 is a perspective view of a zero insertion force connector block 10 for a printed circuit card 12. The connector block 10 has a number of contacts (to be described in more detail later) which can provide an electrical link between connector pins 14 on block 10 and corresponding conductive paths 16 on printed circuit card 12. A processor 18 drives a solenoid 20 having a reciprocating armature 22. The armature 22 acts on a pair of lever arms 24 and 26 which open and close banks of contacts on the opposite sides of the card-receiving slot 28 in connector block 10.

Referring to Fig. 2, each serpentine contact 30 within connector block 10 is an integral extension of one of the connector pins 14. The contacts are held in place in a molded base member 32. The distal end of each contact 30 is received within a recess in the surface of a rotatable rod 36. The angular position of each rotatable rod 36 is controlled by the position of the lever arm 24 or 26. When the rods 36 are in the position shown in Fig. 2, the card contacting regions 38 on each contact are withdrawn from the card-receiving slot 28.

When the rods 36 are rotated to the positions shown in Fig. 3, the contacts 30 are flexed...
