Abstract

Connectors of the "tuning fork" type can be accurately tested for contact force by placing the contacts on a pair of tapered jaws and moving one jaw, while measuring the resulting force on the other.

Connector Force Gage

Connectors of the "tuning fork" type can be accurately tested for contact force by placing the contacts on a pair of tapered jaws and moving one jaw, while measuring the resulting force on the other.

In the drawing, an L-shaped base 1 has a suspended beam 2 secured at its upper end to the base and movable at its lower end by a micrometer spindle 3, which is supported in bracket 4 on the base.

A relief 5 is cut in the beam 2 to permit easy deflection. A block 6 with upright beam 7 is fixed to base 1 so that the respective ends 8 and 9 of suspended and fixed beams 2 and 7 lie adjacent each other. Strain gages 10 are placed on beam 7 and are calibrated to indicate force.

As best seen in the enlarged view, corresponding slots 11, 12 are cut in the two adjacent beam ends 8, 9 to form a split wedge onto which connector 13 can be dropped. Beam 2 is then moved a preselected distance from beam 7 by micrometer spindle 3 and the resulting contact force on beam 7 is measured by strain gages 10. Strain gages 10 are wired to be insensitive to connector placement on the wedge. The split wedge provides self-adjusting placement of the connector for testing.
