## Title
Electrical junction box

## Abstract

A convenient electrical juncture box will be used to repairing a broken household electrical wire, or to connect new wires to multiple locations. It provides all components that need for repairing job in a package. The package will include a conductor unit installed on a base structure, a cover box to enclose the entire electrical circuitry, two nails for securing the electrical juncture box to the wooden beam, and four screws for attaching the cover box to the base structure. The electrical juncture box can be mounted on a wooden beam in an open space such as the attic, crawlspace of a frame or similar structure.

## Background
TECHNICAL FIELD
This invention is generally relate to electrical connection, more particularly, use in repairing damage electrical wires, or provides a convenience to connect an electrical wire to an existing stretching electrical structure.
BACKGROUND
In light frame structures, such as houses, electrical wires are deployed after the assembly of the wooden frame structure is built, and the applicable codes require that the original wire must be secured to the beams using u-shape nails.
When an electrical wire is installed in the 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 the FIG. 1-2, or the home owner wishes to connect an extra electrical wire to an existing wire as illustrated in FIG. 1-4, part 6 the preparation needs to be done to present accident.
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, 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 15 ft=$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 $14.481. The process of the job is described below. Price is collected from Lowes at 35425 Enchanted Pkwy S Federal Way, Wash. 98003, March 2013
As illustrated in FIG. 1-3, in order to repair of such a cutting electrical wire, about 1⁄2 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.
As illustrated in FIG. 1-4 part 6, an extra connection is connected to existing electrical wire. About 1⁄2 an inch of the insulator on the ends of the wires were stripped off, and twisted to hold the wire together by wing twists. Part 1 and 2 are the juncture boxes containing the twisting connections of the electrical wires. Part 3 is the extra electrical wires that needs 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. Part 6 is the new electrical wire connected to an existing electrical wire.
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 a fire.
The invention of the Electrical Juncture Box (EJB) will provide a more secure and easier way to repair a broken electrical wire, or connect an electrical wire to existing an electrical wire. It is also a better way to eliminate the arcing of a loose electrical connection.
SUMMARY OF THE INVENTION
The EJB is invented to prepare or extend electrical wires in an open space in a frame structure such as an attic and crawl space. It will simplify the working process, reduce the cost, and limit fire accident. The EJB will provide all of the necessary components in a package that is needed for repairing a broken electrical wire.
The package provides a conductor base, a cover box, two 11⁄2 inch nails, and four 6 9/16 size screws.
The conducting components of the EJB are two (2) inches long. This provides room for wire connections.
Before any electrical wire is connected to the EJB, the base of the EJB must be secured on a existing frame structure.
In case the wire was cut, a 1⁄2 inch insulator of both ends of a cutting wire will be stripped off, slide nude wires into the slots, and tie the screws down secure the wires. In FIG. 17, part 5 illustrated how the broken wires are installed in the slots.
In the case that the electrical wire was not cut, but its insulator was damaged, then the insulator of the wire will be stripped off for about 2 and 1/16 of inches long. The wires will be slid into the slots, and screwed down to secure the wires. FIG. 17, part 7 shows how the wires are installed into the slots.
As illustrated in FIG. 17, the new electrical wires are connected to an existing electrical wire. It is done through the same process of repairing cut and/or damaged electrical wires.
After the wires are secured on the conductor unit of the EJB, the cover box is installed to cover and secure it from the surrounding environment.
A convenient electrical junction box of this type is used to interconnect power wires to which appliances or other equipment can be attached.
