Self Locating Array Connector

This self-locating connector minimizes difficulty in making connections to modules with large numbers of pins.

The self-locating array connector consists of an array of control springs 10 with "tails" 12 soldered into a mother board 14 and shanks 16 retained in a dielectric housing 18. The shanks 16 may be pressed firmly into the housing which eliminates solder joint stresses or, if preferred, retained loosely.

One side 20, the non-contact side, of each spring 10 is coated with a suitable dielectric 22, such as parylene, polyimide, or TEFLON*, all of which offer a low coefficient of friction, toughness, and abrasion resistance. Both sides of the springs may be formed to provide a high-pressure contact with the module pin
24. The springs 10 are of commonly available material, such as Be-Cu, and are suitably heat treated and plated to resist corrosion and oxidation.

To effect a connection, the module is first roughly located with the connector such that the pin array is staggered with respect to the spring array (Fig. 1). The module is then actuated leftward with respect to the connector such that each pin 24 abuts against the non-contact side of a spring and against the contact side of an adjacent spring. Further actuation compresses the spring halves until each pin is wedged, as shown in Fig. 3. In this fashion, each module pin is squeezed between two equal and opposing forces such that the net bending moment or shear force on any pi...
