Problems solved by technology

[0006] Under certain dynamic conditions, such as vibration and shock, or large temperature changes, the wires in a twist-on connector may loosen, reducing the resistance of the twist-on connection due to increased resistance or reduced contact area or both. Integrity of connection between conductors in the

Embodiment Construction

[0017] refer to figure 1 , reference numeral 10 represents an existing rotary connector. The connector 10 includes an electrically insulating housing 11 having an open end 12 and a closed end 13 , wherein the diameter of the open end 12 is greater than the diameter of the closed end 13 . The helical wire 16 extends axially inwardly within the housing 11 . The diameter of the helical wire 16 near the open end 12 of the housing 11 is larger than the diameter of the helical wire 16 near the closed end 13 of the housing 11 so that the wires are squeezed into tight contact with each other when they are threaded into the helical wire. Although this embodiment shows the helical wire as a metal spring, it is conceivable that the helical wire could be integrally formed in the housing of the rotary connector.

[0018] figure 2 One embodiment of the invention is shown having a self-adhesive lubricant 15 located at the closed end 13 of the connector 10 . The self-adhesive lubricant 1...

Abstract

An improved twist-on wire connector that permits the user to form the junction ends of wire leads into a low resistance electrical connection with the twist-on wire connector including a self adhering lubricant located along a portion of the interior of the twist-on wire connector. As the wires are drawn into the spiral thread, the torque applied to the wires increases until the wires can no longer be hand twisted into the wire connector. Once the wires are drawn into contact with the lubricant the torque resistance, which is a result of frictional resistance between the wires and the spiral thread, decreases while the radial compressive forces between the wires and the spiral thread are substantially unaffected. Consequently, the rate of torsonial resistance decreases allowing the wires to be brought into further electrical contact along a greater length through only hand tightening while at the same time the radially compressive forces on the wires are greater thus ensuring a low resistance electrical contact that remains stable over an extending period of time. Because only a small amount of self-adhering lubricant is needed within the wire connector to provide an enhanced low-resistance electrical connection problems of the self-adhering lubricant accidentally coming into contact with the exterior housing of other twist-on wire connectors is minimized even if not caps are used on the twist-on wire connectors.

Description

technical field [0001] The present invention relates to a connector, and more particularly to a twist-on connector, which is provided with a lubricant to reduce the torque required to secure the wires in said connector while ensuring that the wires are securely engaged so that Normal thermal expansion and contraction or shock and vibration will not cause the wires to loosen within the connector. [0002] This application claims priority to Provisional Application Serial No. US 60 / 251,111, filed December 5, 2000, and entitled Low Torque Rotary Connectors. Background technique [0003] Connector concepts for connecting two or more wires together by twisting caps on the wires are known in the art. Connectors are well known in the art and typically include a housing with a tapered, threaded interior to allow a user to insert a wire into the tapered opening. To use the connector, the user inserts the twisted end of the wire into a cavity inside the connector. The user then hol...
