Abstract

This zero insertion force pivoted pin connector provides for the replacement of each individual contact in case of breakage. As shown at A, each contact assembly consists of base 1 to which end plates 2 and 3 are secured. A rod 4 extends the length of the unit and provides a pivot for the individual contact units 5. An air tube 6 extends the entire length of the contact assembly passing through an oval opening in each contact unit.

Pivoted Pin Connector

This zero insertion force pivoted pin connector provides for the replacement of each individual contact in case of breakage. As shown at A, each contact assembly consists of base 1 to which end plates 2 and 3 are secured. A rod 4 extends the length of the unit and provides a pivot for the individual contact units
5. An air tube 6 extends the entire length of the contact assembly passing through an oval opening in each contact unit.

As shown at B, each contact unit includes a pin 7 to which spring contact 8 is fastened. The spring portion makes contact with stationary pin 9 in the interface board 10, whereas pin 7 contacts spring 11 in housing 12 that supports the card under test. A space 13 between the contact units allows compression springs 14 to bias the individual contact units toward each other when the air tube is deflated. To maintain pins 7 in alignment, the lower portion of each contact portion which surrounds the pivot rod 4 is less than one half the thickness of the upper section supporting the pin and are guided by combs 15 extending from the base.

In operation, the air tube 6 is inflated to rotate the contact units to a position where the pins 7 extend upward in the correct position for entering the housing
12. After the housing is in position, the air tube is deflated allowing the pins to rotate toward each other 14 assure that the pin in each contact unit exerts the same pressure, thereby providing dependable electrical contac...
