Terminal Clip for Printed Circuit Card

This is a terminal for making connection to the edge of a printed circuit board without requiring plated through-holes in the board or handling of individual terminals.

A strip of approximately thirty identical solder-plated, S-shaped terminals 10, drawing 1, is made by punching and forming a piece of weldable metal. Solder plating exists in all strip portions except those to be welded. The terminals are held in registration by selvages 12 and 14. A terminal strip is pr essed onto the edge of printed circuit board 16 so that the terminals 10 lie on the surface of solder-plated lands 18 on the upper and lower surfaces of board 16. Spring tension of terminals 10 retains them. The edge of board 16 is then dipped in hot oil to reflow the solder to mechanically and electrically fix terminals 10. Selvages 12 and 14 are then broken off. Terminals 10 can then be welded to terminals 20 of core plane 22.

The arrangement of drawing 2 shows how the terminals interconnect two circuit boards 30 and 32 and core plane 34, and, as in drawing 1, provide the core plane weld connection 36.
