Double type branch sleeve of distribution line {BRANCH SLEEVE OF DISTRIBUTION LINE}

The present invention relates to a branch sleeve, and more particularly, the main wire and the lower wire, which are wired by the sleeve body, are firmly bound by using the binding band and the first and second connectors, and the shape of the sleeve body is processed into a W shape. When the sleeve body is installed on the main line, the sleeve body is pulled in both directions and the both ends are firmly connected to the main line. When the sleeve body is installed on the main line and the tension weakens in the main line, the sleeve body pulls the main line and the main line is tensioned. It relates to a W-type branch sleeve of a distribution line so as to compensate for this problem.

In general, a low-voltage wire, which is a low-voltage wire that performs a role of transmitting power to electric wires through a pole transformer in a wire of a high-voltage wire, is connected by a branch sleeve for connecting a low-voltage wire.

Such a branch sleeve is a means for connecting and connecting a high-voltage wire and a low-voltage wire-down wire, and is disclosed in Korean Utility Model No. 20-0198529 as a prior art for a conventional branch sleeve.

1 is a perspective view showing a conventional branch sleeve disclosed in Utility Model 20-0198529.

Referring to FIG. 1, the branch sleeve A 'has a first accommodating portion 2' formed thereon with a main line inserted therein and a second accommodating portion 3 'with a lowering cut line inserted therein. The first accommodation portion 2 'is open at one side so that the main ship can be inserted in the lateral direction, and an insertion groove is formed, and the second accommodation portion 3' has both ends opened and a passage inside. Is formed.

Therefore, the main ship is inserted from the side through the insertion groove of the first accommodating part 2 'in a state in which power is supplied to the main ship (hereinafter referred to as a' live state '), and the lower accommodating line to the second accommodating part 3'. After inserting the branch sleeve (A ') is fixed by pressing with a compressor (not shown).

However, in the conventional branch sleeve, there is a concern that the main ship is separated from the insertion groove and an electrical safety accident may occur due to this.

Accordingly, the development of branch sleeves for more tightly and safely connecting the main line and the lower line is being actively performed, and the prior art for other conventional branch sleeves for improving the problems of the conventional branch sleeves is registered in Korea. It is disclosed in patent 10-0659024.

2 is a perspective view showing another conventional branch sleeve disclosed in Patent 10-0659024.

Referring to Figure 2, the other side of the conventional sleeve sleeves "S" in the shape symmetrical in the vertical direction, the one end is formed with the main winding fastening curved downwards, the other end is the lower down fastening fastening curved upwards It is formed, the center is formed in the upper and lower center, the upper and lower operating holes are formed in the upper and lower portions of the center, respectively, the sleeve body 10 is formed in the insertion hole in both sides;

Accordingly, the electricity of the conductor wire 11 is applied to the first connector 120 through the connection terminal 127, the electricity applied to the first connector 120 is the top bar 111 and the diagonal bar and It is applied to the second connection bar 131 through the lower bar 113.

Thereafter, the inlet line 20 is wired into the inlet groove 141 of the binding connector 140.

Thus, when the lower line 20 is wired to the inlet groove 141, the both ends of the binding connector 140 is closed to press the lower line 20 in the inlet groove 141.

Thereafter, the fastening pipe 145 is coupled to the outer surface of the binding connector 140. Accordingly, the binding connector 140 can be maintained in a pressurized state of the lower line (20).

Thereafter, by fastening the upper portion of the coupling connector 140 to the connection hole 135, the main line 10 and the lower line 20 is the sleeve body 110, the first connector 120, the second connector 130 ) And the fastening connector 140 is electrically rigidly connected.

Accordingly, the W-type branch sleeve of the distribution line not only firmly binds the main line and the lower line wired with the sleeve body by using the binding band and the first and second connection ports, but also processes the shape of the sleeve body into a W shape. When the sleeve body is installed on the main line, the sleeve body is pulled in both directions and the both ends are firmly connected to the main line. When the sleeve body is installed on the main line and the tension weakens in the main line, the sleeve body pulls the main line to maintain the tension. To help. In addition, by simplifying the structure of the branch sleeve, it is possible to install the branch sleeve on the ship with a minimum manufacturing cost and construction cost.
