Description

Electrical Connector Box

Technical Field

[0001] This invention is generally relating to electrical connection, more particularly, use in repairing damage electrical wires, or provides a convenience to branch an electrical wire to a different location in a building structure.

Background

[0002] In light of a building frame structures, such as houses, buildings, electrical wires are deployed after the structure is built, and the applicable codes require that the electrical wire must be secured to the beams using u-shape nails.

[0003] When an electrical wire is installed in a building structure, it is stretched out and

secured onto the structure as illustrated in FIG 1-1. If this electrical wire was cut as illustrated in FIG 1-2, or need to connect an extra electrical wire to an existing wire as illustrated in FIG 1-3.

[0004] Unfortunately, the stretched and secured wire in the existing structure normally does not provide spare length for twisting together in the reparation as illustrated in FIG. 1-3 parts 1 and 2. A portion of electrical wire (3), about a foot long, has to be added and other parts have to be purchased separately for the reparation. The following listed parts are needed:

- Two net work boxes, 39 cents for each = $0.78

- Electrical wire, $8.52 per 15ft = $8.52

- Two net work box covers, $1.29 for ea = $2.58

- A bag of wing twists (25 pieces per bag) = $2.60

The total cost of the material will be approximately S14.48¹. The process of the job is described below.

¹ Price is collected from Lowes at 35425 Enchanted Pkwy S Federal Way, WA 98003, March 2013 [0005] As illustrated in FIG 1-3, the repairing such a cutting electrical wire, about ½ an inch of the insulator on the ends of the wires needs stripped off, twisted, and held together with wing twists. Juncture boxes 1 and 2 contain the twisting connections of the electrical wires. Part 3 is the portion of electrical wires that need to be added between the two juncture boxes to extend the length of the wires so that they can be twisted together by wing twists. Part 4 is the input electrical wire. Part 5 is the output of the electrical wire. Part 6 is the new electrical wire connected to an existing electrical wire.

[0006] This repairing and connecting method would be costly and time consuming for home owners and electrical technicians. Also, the electrical wire would easily get loose and might arc to cause fire.

[0007] The invention of the Electrical Connector Box (ECB) will provide a more secure and easier way to repair a broken electrical wire, or connect an electrical wire to an existing electrical wire. It is a better way to eliminate the arcing of a loose electrical

connection. It also can be used to extent or to branch electrical wire to a new location.

Summary of the Invention

[0008] The ECB is an invention for repairing or to extending electrical wires in an open space in a wooden frame structure such as attic, crawl space, or outside wall of a building structure. It will simplify the working process, reduce the cost, and limit the cause of the fire hazard. The ECB will provide all the necessary components in a package for repairing a broken wire, branch, or extend a wire to a new location.

[0009] The conducting components of the ECB are about three (3) inches long. This provides electrical wire length for the connections.

[0010] The ECB must be secured on a frame structure when it is used.

[0011] The device in Fig F8-2 is used to prepare a single broken electrical wire. The device in FIG 18 is used to add to the existing electrical wire a new electrical wire and branch it to a new location. However, device in FIG 18 can be used in place of device in FIG 8-2. A ½ inch insulator of both ends of the wire will be stripped off, insert the naked part of the wire into the tubes as shown in Fig 2-3 part 2, and the screw is tied down to secure the wires in place. Part 1 in FIG 2-3 is insulated part of the wire.

[0012] The device in FIG 12 is used for one to one connection that needs conduit. The device in FIG 22 is used for one to multiple connections that needed conduit.

[0013] After the wires are secured in the conductor unit of the ECB, the cover is installed to cover and secure it from the surrounding environment.

[0014] A convenient electrical connector box of this type is used to interconnect power wires to which appliances or other equipment can be attached.
