The present invention relates to a cable connecting device, in particular, in connecting large capacity cables to prevent poor connection, improve the assembly and quality and at the same time have a water tightness, and also to reduce the cost of the product by eliminating the block junction It relates to a cable connection structure.

1 is a front view showing the configuration of a conventional cable connection device, wherein the first and second terminals 101 and 111 of the first and second cables 100 and 110 are connected to the guide hole 121 of the block junction 120. The bolt 130 and the nut 140 are fastened through the block junction 120, and the first and second cables 100 and 110 are interconnected and fixed.

However, in the conventional cable connection device, the bolt 130 and the nut 140 are inserted into the block junction 120 by inserting the first and second terminals 101 and 111 of the first and second cables 100 and 110. Since the assembly of the cable is not easy, it is not only easy to assemble the cable, but also often leads to poor connection due to water tightness, and also has the disadvantage that the cost of the product is increased by using the expensive block junction 120.

An object of the present invention is to provide a cable connection device that can improve the assemblability and at the same time have a watertightness to prevent a connection failure, and also reduce the cost of the product by eliminating the block junction.

In order to achieve the above object, the present invention secures a first terminal to a first cable, and combines a first connector formed with a male screw to surround the first terminal in the first cable, and also the first cable and the first connector. Through one side of the heat shrink tube is configured by sealing, combining.

The second terminal is fixed to the second cable, the spacer bushing is coupled to the outer circumferential surface of the second cable, and a locking step is formed on the outer circumferential surface of the tip of the spacer bushing.

The second connector formed with a female thread on the spacer bushing is bound so as to enclose the second terminal, and the second connector is movable by a predetermined distance from the spacer bushing, and the heat shrinkage to seal the second cable and the second connector. Coupled to the tube, characterized in that configured through the waterproof rubber between the second connector and the second terminal.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

2 is a cross-sectional view showing the configuration of the cable connection device of the present invention.

As shown in the drawing, the first connector 20 is fixed to the first cable 10, and the first connector 30 having the male screw 31 is formed to surround the first terminal 20 in the first cable 10. The heat shrink tube 40 is sealed and coupled through one side of the first cable 10 and the first connector 30.

The second terminal 60 is fixed to the second cable 50, the spacer bushing 90 is coupled to the outer circumferential surface of the second cable 50, and the locking jaw 91 is attached to the outer circumferential surface of the tip of the spacer bushing 90. To form.

The second connector 70 having the female thread 71 formed therein is coupled to the spacer bushing 90 to surround the second terminal 60, and the second connector 70 is spaced apart from the spacer bushing 90 by a predetermined distance. In order to be movable, and to combine the heat shrink tube 80 to seal the second cable 50 and the second connector 70, the waterproof rubber between the second connector 70 and the second terminal (60) It is composed through intervening.

Accordingly, in the present invention, when the first connector 30 is inserted into the second connector 70 and the male screw 31 and the female screw 71 are mutually fastened and fixed as shown in FIG. 2, at this time, the first and second terminals 20 are connected. As the 60 is interconnected, the first and second cables 10 and 50 are quickly and easily connected and assembled.

Here, the first and second cables 10 and 50 are connected and connected at the same time by screwing the first and second connectors 30 and 70 together, so that assembly is quick and easy, and waterproof rubber 80 and The heat shrink tubes 40 and 80 improve the watertightness of the connector connection portion and at the same time prevent connection failure.

As described above, the present invention, by screwing the first and second connectors together and the first and second terminals of the first and second cables are connected to each other, the connection, connection of the cable is made quickly, easily, As watertightness is imparted, poor connection of the connector connection part is prevented, and the advantage of contributing to cost reduction of the product can be achieved by eliminating the use of block junctions.
