Connector wire spring element - for connection of line wire with contact pin with polygonal cross-section has end portion formed by loops

摘要

The end of the spring wire element (1) is formed into a U-shaped loop (2) into which the line wire (3) is inserted, so that its end (4) to be contacted points to the open side of the loop (2)section (5) of the spring wire is helically wound around the line wire (3) and the parallel end of the free arm (6) of the loop (2)into a cylindrical or conical helical spring whose inner dia., is smaller than that of the smallest dia. of the contact pin (8).
