Abstract A terminal system is described for use with circuit boards, which enables the terminals to be subsequently interconnected using any of a variety of point-to-point wiring methods. Each terminal includes a sleeve with a plated-through hole, the upper portion of the hole holding a contact clip member that receives leads of circuit components, and the lower portion of the hole formed to receive any of a variety of wire termination devices. A circuit board assembly is formed by first press-fitting the sleeves into holes in the board, from the component side of the board. A selected one of the many types of wire termination devices are later inserted into the bottom of the sleeve from the wiring side of the board. Each sleeve has a spline at its lower portion and a barb at its upper portion, which together resist rotation or withdrawal of the sleeve from its press-fitted position while avoiding warping of the board.
A pin system for installation in a circuit board that has upper and lower opposite surfaces and a plurality of board holes, comprising: a main shaft having upper and lower ends, said shaft formed so its lower end can pass through said upper board surface and substantially through one of said board holes so said shaft lies in said board hole, said shaft being rigid and including an exterior surface for preassembled force fit in said board hole, and said shaft having a hole in its lower end; a plurality of wire termination devices each having an upper end that can fit into and anchor itself in said hole in said lower end of said shaft, each termination device also having a lower end forming a means for holding onto and making electrical connection with a wire conductor.
