Back side pin removal tool

A pin removal tool for removing a single pin from a multiple pin electrical connector comprising

• a body member having an axial bore extending therethrough, said body member having a thin wall sleeve portion at a first terminal end, said bore having a first diameter through a portion of its axial length and a reduced diameter portion defined by the inner wall surface of said sleeve portion;
• a plunger member including a shaft with a first diameter that is slidably received within said body member bore first diameter portion and a reduced diameter terminal end portion that is slidably received in said body member sleeve reduced diameter;
• and
• a concave surface presented at the terminal end of said plunger member reduced diameter terminal end portion.

A pin removal tool for removing a single pin from the connector body of a multiple pin electrical connector comprising

• a single piece integral body member having a central bore extending therethrough, said body member having a flange at one end, an intermediate portion, and a reduced diameter portion at the end opposite said one end;
• said bore having a first diameter within said flange and said intermediate portion and a reduced diameter within said reduced diameter portion which forms a thin wall sleeve terminal end portion;
• and
• a plunger member including a shaft having a first diameter portion received in and slidable within said body member first diameter bore and a reduced diameter portion extending axially therefrom and received in said body member sleeve terminal end portion, said reduced diameter shaft portion having a concave terminal end surface;
• said plunger shaft reduced diameter portion being retractable into said body member sleeve terminal end portion when moved in one axial direction and slidable in the direction opposite said one axial direction to project beyond the distal end of said body member sleeve terminal end portion, whereby when said body member sleeve surrounds a pin to be removed, said shaft can be advanced to align and drive the pin from the connector body and when a pin is resident in a host device via, said body member sleeve can be aligned with the via and the plunger shaft advanced to cause said shaft reduced diameter portion to extend into the via beyond the sleeve end to align and drive, from the connector body, the pin which is radially confined by the walls forming the via.
