Abstract

A solderless, generally elongated, circuit board conductor adapted to be received and held in a plated-through hole formed in the circuit board in order to provide an electrical connection between a conductive plating deposited on the interior surface of the hole of another circuit element. The conductor includes a compliant section which is adapted to be received in the hole in contact with the plating and allowing selective insertion and removal of the conductor into and out of the hole. The compliant section generally comprises a plate section with a resilient finger struck out therefrom. The finger has an apex portion to contact the plating of the hole. Also disclosed is a connector assembly which is selectively mountable on a circuit board and which includes an insulative base portion with a plurality of solderless elongated electrical terminals mounted therein. Each terminal has a lower compliant section of the type described above which is adapted to be received in plated-through holes formed in the board in contact with plating on the interior surface thereof. An insertion tool is provided that simultaneously cooperates with the terminals and base portion for supporting the terminals in the base portion when the assembly is mounted in said board.

Claims3

Dependent claims

A connector assembly that is selectively mountable on a circuit board adapted with a plurality of holes with a conductive plating deposited on the interior surface of said holes, said connector assembly including

an insulative base portion with at least one sidewall having an external surface and a plurality of terminal receiving recesses formed in said base portion, and
a plurality of solderless, elongated electrical terminals, one mounted in each recess, each terminal having a top portion adapted to electrically contact another circuit element and a lower compliant section extending below the base portion adapted to be received in said holes in contact with said plating and allowing selective insertion and withdrawal of said terminals into and out of said holes,
the improvement comprising:
said terminals located adjacent said sidewall and having land portions intermediate said top portion and compliant section;
a slot formed in the external surface of the sidewall providing external access to the recesses and the intermediate land portions mounted therein;
and
a tool having an elongated arm that is insertable from the external surface of said sidewall into the slot and extending into the recesses for simultaneous engagement with said land portions for supporting said terminals in said base portion during mounting of said assembly to said board, whereby relative movement of said terminals with respect to said housing is prevented during mounting of said connector assembly by engagement of said tool with said intermediate land portions and said side wall.
