Electromechanical Extraction Tool for Microminiaturized Spring Connectors

This is a special tool device adapted for the replacing of damaged or broken miniaturized spring-type electrical connectors in printed-circuit boards or the like.

The connector extraction tool, as shown in the drawing, is mounted to an X-Y table, not shown, that may be positioned over the general area of the damaged connector in a printed-circuit board. A forty-power scope is employed to locate the precise connector to be worked on, after which the X-Y table is locked in place. The scope is then replaced with the electromechanical extraction tool.

The lock wheel 10 on top of the tool is rotated, which causes the two extraction arms 11 and 12 to open the jaw tips 13 and 14.

This portion of the tool is then pushed to the board 15 surface and the lock wheel 10 is rotated in the opposite direction, thereby causing jaw tips 13 and 14 to grip the damaged connector 16. The long arms 11 and 12 have a ratio such that their movement about the pivot point 18 enables an accurate movement of the jaw tips 13 and
14. Internal compression springs 21 located in the housing 19 of the tool exert an upward pressure on the gripped connector 16.

A current from a power supply is connected via the wires 22 and 23 and passed through the insulated extractor arms 11 and 12 to the tips 13 and 14, and then through the miniaturized spring connector 16, thereby melting the solder around the connector 16.

The extraction t...
