ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to a solderless twist on wire connector and a method of making a solderless twist on wire connector and, more specifically, to making a wire junction encapsulating twist on wire connector by securing a prior art twist on wire connector in a shell to produce a wire junction encapsulating twist on wire connector that can in one operation permit the user to simultaneously compress the junction ends of electrical wires into low resistance electrical contact while encapsulating the junction ends of the electrical wires in a solderless substance.
BACKGROUND OF THE INVENTION
The concept of twist on wire connectors for connecting the junction of two or more wires together by twisting a cap on the wires is old in the art. Twist on wire connectors are well known in the art and generally comprise an outer housing with a tapered threaded interior to permit a user to insert wires into the tapered opening. Typical examples of prior art twist on wire connectors are shown in U.S. Pat. Nos. 3,497,607; 3,875,324; and 4,691,079. To use a twist on wire connector, the user inserts the twisted ends of electrical wires into a cavity on the inside of the twist on wire connector. The user then holds the wire in one hand and with the other hand twists the twist on wire connector. The twisting action pulls the junction ends of the wires into a low resistance electrical contact.
If the connector is located in a wet location it is necessary to place a waterproof sealant around the connector. In order to prevent water or moisture from entering the connector and forming an oxidation layer over the ends of the wire the user inserts the twist on wire connector and the wire into some type of a waterproof potting compound. The compound may be either a non hardening or a hardening compound. In either case the compound creates a waterproof capsule over the twist on wire connector and the junction ends of the electrical wires.
Still other wire connectors permit simultaneously forming an electrical connection while the unstrapped electrical leads are located in a sealant by pushing a knife like member through the insulation on the electrical lead to make contact with the electrical wire beneath the insulation. Such wire connectors use separate compartments to hold each unstripped and require the connector to form the sole connection between separate wires and thus may not form a good electrical connection unless firm electrical contact is made between the knife like members and the electrical lead.
The present invention provides an improved twist on wire connector that permits the user in one continuous action to simultaneously form the junction ends of stripped wire leads into a low resistance electrical connection while the stripped electrical leads are surrounded by an encapsulating agents such as a waterproof sealant to form a waterproof covering around the junction ends of the wire leads.
The process of making a prior art twist on wire connector typically involves molding a shell around a spiral coil to create a prior art twist on wire connector. The present invention includes a second molding step wherein the prior art twist on wire connector is placed in a mold and a second shell is molded around the prior art twist on wire connector to produce a wire junction encapsulating twist on wire connector having a chamber that can contain an encapsulating material so that in one operation can permit the user to simultaneously compress the junction ends of electrical wires into low resistance electrical contact with each other while simultaneously encapsulating the junction ends of the electrical wires in a sealant.
DESCRIPTION OF THE PRIOR ART

The Nicolazzo U.S. Pat. No. 2,416,943 shows a wire connector that squeezes the ends of the wires between an outer housing and an inner housing.
The Bird U.S. Pat. No. 3,083,260 shows a cup shaped body that has a metal cement or putty located around the twisted ends of two electrical leads.
The Swanson U.S. Pat. No. 3,497,607 shows a wire connector that has a spring in the cavity of the connector that cuts through the insulation on the wires.
The Smith U.S. Pat. No. 4,039,742 shows a waterproof splice that uses an enclosed tube containing a sealant that covers the electrical connection between the wires.
The Erixon U.S. Pat. No. 4,107,453 shows a wire connector with an inner and an outer housing with the ends of the wires located between the inner and the outer housing. Twisting the outer housing while holding the inner housing twists the wires into electrical contact.
The Dauser U.S. Pat. Nos. 4,295,004 and 4,446,332 show a solderless wire connector where a cap is squeezed over the ends of the wires to provide an electrical connection.
The Eaton U.S. Pat. No. 4,751,350 shows a cap containing a sealant and retentions to engage the end of a wire inserted into the cap to provide a sealing device around the end of the wire.
The Ustin U.S. Pat. No. 2,870,239 shows a wire connector with a splice cap that is permanently crimped to the conductors to hold the conductors in mechanical and electrical contact.
The Vogel U.S. Pat. No. 3,109,051 shows an electrical wire connector that includes parallel spaced surfaces to insert the ends of the twisted wires in.
The Krup U.S. Pat. No. 3,483,310 shows a connector that has a sleeve that contracts to prevent the sleeve from being withdrawn from the connector.
The Anderson U.S. Pat. No. 3,550,765 shows a sleeve that contains a viscous or flowable substance such as an uncured cement that is hardened to hold the electrical leads in the connector.
The Waddington U.S. Pat. No. 3,875,324 shows a wire connector with a tapered spring located in the connector.
The Caviar U.S. Pat. No. 4,491,686 shows an electrical connector with coverings that can be pierced by inserting a sharply pointed object. A potting compound is then placed around the wires.
The U.S. Pat. No. 4,691,079 shows a screw on wire connector with a shell that is easier to manufacture.
The Netherlands patent 56183 shows a hook on the side of some type of a connector.
The Bumpsted U.S. Pat. No. 3,937,870 shows a connector including a potting cement to cement the wires in a solid mass.
The Penfield U.S. Pat. No. 3,597,528 shows an an electrical wire connector with an insertable plastic plug that contains a plastic bonding agent.
The Smith U.S. Pat. No. 3,934,076 shows an electrical connector with a pre filled and premixed sealant for encapsulating the end of the wires.
The Smith U.S. Pat. No. 4,314,094 shows a container for spliced cables.
The Smith U.S. Pat. No. 4,053,704 shows a key for forming an enclosure for two or more wire cables together.
