Abstract
The present invention discloses novel twist-on wire connectors. These connectors include spring inserts having cross-sectional shapes which reduce the amount of material necessary to manufacture the spring insert without compromising the holding or gripping ability of the wire connectors. The cross-sectional shapes eliminate excess material in the spring insert that plays no part in holding and gripping the electrical wires that are to be joined and held together.
Claims14
A twist-on wire connector for joining the ends of a plurality of electrical wires, comprising:
- an insulating shell having a body wall and an end wall, said walls having internal surfaces and defining an internal cavity with an opening at one end for receiving the electrical wires;
- and
- a spring mounted in the internal cavity of the shell and engaging the internal surface of the body wall, the spring including a plurality of coils which have a hexagonal cross-section, said hexagonal cross-section having at least four substantially equal sides.
