ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to electrical wedge connectors and, more particularly, to electrical wedge connectors with blades for piercing conductor insulation.
2. Prior Art
European Patent Office publication No. EP0810688 discloses a wedge connector for piercing through insulated conductors. U.K. patent publication No. 2065994 also discloses a wedge connector with a wedge capable of piercing through insulation on a conductor. U.S. Pat. No. 5,679,031 discloses retention barbs on a wedge connector shell. U.S. Pat. No. 5,911,604 discloses an insulation piercing wedge connector with seal.
SUMMARY OF THE INVENTION
In accordance with a first embodiment of the present invention, an electrical wedge connector is provided. The electrical wedge connector comprises a shell, a wedge section, and at least one elongated bar element. The wedge section is sized and shaped for being inserted into the shell for connecting two electrical conductors to each other. The wedge section has at least one passageway formed therethrough. The elongated bar element is mounted to the wedge section. The elongated bar element is located in said at least one passageway of the web section. The elongated bar element has piercing protrusions for effecting an electrical connection between each of the two conductors and the elongated bar. The wedge section includes at least one stop member for retaining the elongated bar element to the wedge section in at least one direction.
In accordance with a second embodiment of the present invention, an electrical wedge connector is provided. The electrical wedge connector comprises a shell, and a wedge assembly. The wedge assembly is sized and shaped for being inserted into the shell for connecting two electrical conductors to each other. The wedge assembly comprises a wedge block, and an elongated bar element located in a passageway formed in the wedge block. The elongated bar element has piercing protrusions for piercing the two conductors, and electrically connecting the two conductors to the elongated bar element. The elongated bar element includes a resilient sheath. The elongated bar element has a first configuration in which the piercing protrusions of the elongated bar element are at least partially hidden in the resilient sheath, and a second configuration in which the piercing protrusions are exposed out of the resilient sheath.
