Description

Apparatus for Spiral Connection of Wires}

The present invention relates to a mechanism for short circuit in indoor electrical wiring, and more particularly, to an auxiliary mechanism used for short-circuit work such as braiding before connecting to indoor power supply terminals.

When building a building, electrical wiring work must be done. The final wiring work in the building will be an indoor power terminal, or an outlet. There are usually three types of wires to be connected to the power terminals and connected to each other. Ground wires, + wires, and-wires. Each of these wires is generally inserted into three wires. A series of short-circuits are required to form one circuit by twisting one strand of wire, a total of four strands to be wired directly into the wire.

Until now, the above short-circuit work was performed by manually twisting the wires and covering the insulated wire connector tabs, so there was no proper measure even though it was a very labor-intensive work.

The above shorting work requires about 100 times in one unit building, and in the case of a multi-unit house, the manpower and time spent on the work will be enormous.

In addition, the worker manually twisted several wires using only a simple tool such as a pliers, and put a lot of effort into inserting insulated wire connector tabs.

In addition, the increase of working time not only caused the cost to increase, but also the incidence of errors was high.

In order to improve the inefficiency in the short-circuit operation in the indoor wiring described above, the present invention uses an electric rotary tool such as a drilling machine to twist the electric wire easily, and the first assembly and the second joint to be bitten by the electric rotary tool. Its purpose is to provide easy and perfect handling of short-circuit work for braiding and insulated connector tabs.

<Name of Main Code in Drawing>

10: upper hole (Hole) 11: lower hole

15, 25, 45: polygonal bit 16: the first assembly upper body

17: lower body of the first joint 31: uneven groove

36, 46: upper second conjugate 37, 47: lower second conjugate

In order to solve the above technical problem, the present invention is a short-circuit work aid using the rotational force of the electric rotary tool,

The first body is characterized in that the upper body is a polygonal column shape therein is formed a plurality of holes through which the wires are drawn in one strand through and a polygonal bit formed integrally at the center of the bottom of the lower body and

The upper body of the first assembly to accommodate the upper body of the first assembly having a cylindrically hollow inner space having a plurality of uneven grooves in the upper part to accommodate the insulated wire connector tabs It provides a second conjugate to be connected to the first conjugate, including an inner space of the shape and size, such as.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1a to c is an exemplary view showing a first conjugate according to the present invention.

FIG. 1A is a perspective view of the first conjugate viewed from the outside, and when viewed from the A side in front, as shown in FIG.

The upper hole (Hole, 10) is a passage through which several strands of wire are drawn one by one, and the size of the inlet is determined by the thickness of the wire. 10) It may be desirable to form the outer side to have a larger diameter than the passage 10 into which the actual wire is to be drawn.

The lower hole 11 indicates a lower portion of the hole (Hole) penetrating the first assembly, and the electric wire drawn into the upper hole 10 may be drawn out through the lower hole.

The polygonal bit 15 is connected to an electric rotary tool such as a drilling machine to perform a role of a rotary shaft, and is integrated with the first assembly so that the polygonal bit 15 can be directly connected to the electric rotary tool without the need for preparing a separate rotary drill bit.

As the polygonal bit 15, a structure capable of rotating another object such as a hexagonal or a quadrilateral is sufficient.

However, as described above, the socket bit may be formed only in the first assembly without integrating the polygonal bit with the first assembly, and a conventional rotary drill bit may be used as it is.

In addition, the number of holes penetrating through the first assembly may be variously manufactured according to the number of strands of the wires that need short circuit work.

In the drawings, as an example, the first assembly body is divided into upper and lower parts, and the upper body 16 is formed in a rectangular pillar, and the lower body 17 is formed in a cylindrical shape, but the upper body 16 is not only a rectangular pillar type. If there is a structure that can rotate other objects, the lower body 17 may be manufactured in the same shape as the upper body 16.

2 shows a mode of twisting and connecting by using the first joined body.

The wire strands are introduced into the upper hole 10 of the first assembly and drawn out through the lower hole 11, and then the polygonal bit 25 is inserted into the chuck 29 of the electric rotary tool and rotated to the right. The wires of the strands are tightly twisted and connected spirally.

When the twisted connection is completed in the spiral, the end portion is cut at an appropriate position.

3A to 3E show the structure of the second conjugate.

Figure 3a is a perspective view of the body of the second conjugate from the outside, Figure 3b is a front view observed from the A 'plane, Figure 3c is a front view observed from the B' plane, Figure 3d is a A'-B 'cross-sectional view, 3e is an insulated wire connector tab.

The second assembly upper part 36 is cylindrical with an uneven groove 31 to fit the insulated wire connector tab 33, and the second assembly lower part 37 is an upper part of the first assembly part to accommodate the first assembly part. It is engraved in the same shape and size as the body.

The reason for engraving the first assembly accommodating structure on the lower part of the second assembly 37 is that the braided connection by the first assembly and the covering of the insulated wire connector tab by the second assembly are sequentially performed. This is because it is more efficient to use the first assembly as a drill bit for rotation than to change another bit into the electric rotary tool when using the assembly.

The insulated wire connector tab 33 utilizes what is conventionally produced in a standard size.

The uneven groove 31 is to hold the insulated wire connector tab when the wing 34 of the insulated wire connector tab 33 is rotated, and formed a plurality of uneven grooves to be easily inserted in any direction.

FIG. 4 shows the operation of inserting the insulated wire connector tabs 43 using a second junction to a short cut portion 40 which is properly cut.

The second junction upper part 46 is equipped with an insulated wire connector tab, and the second assembly lower part 47 is connected with the first assembly, and then the polygonal bit 45 is inserted into the electric rotary tool to short-circuit the part 40. When rotated to the right, the insulated wire connector tab 43 is inserted while rotating in a spiral and the short circuit work is completed.

So far, the present invention has been described with reference to one embodiment of the present invention.

However, the core of the present invention is to facilitate the short-circuit work by twisting the wires and covering the insulating tabs, with a first assembly that can accommodate holes and polygonal bits through which the bare wire will pass, and the resultant by the first junction. In order to cover the insulating tab, it will be in the technical idea to provide a second joint that is a structure that can accommodate the insulated wire connector tab and the first joint.

Therefore, the appearance of the upper body of the first assembly, the shape of the polygonal bit or the number of holes of the first assembly, etc. are clearly included in the technical scope of the present invention, even if various modifications are made to the matters belonging to the scope of the present invention. I will.

According to the present invention, it is possible to accurately perform short-circuit work, which is a task of attaching insulated wire connector tabs before and after the power terminal connection, which required a lot of power up to now, to carry out wire indoors. .

Therefore, it is expected that the construction site will contribute greatly to reducing labor costs, preventing industrial accidents at work, reducing the occurrence of errors, and shortening the air.
