Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of a connecting portion of a high-voltage cable, particularly a straight-line connecting portion of a dynamic pressure cable for power distribution.

The conventional connection method for straight contact parts of high-voltage power distribution cables using polyethylene insulated vinyl sheathed cables (CV cables), CVT cables made by twisting three CV cables, etc. is to sleeve the conductors. compressed by or connected by soldering, then insulating tape, protective tape% l') J
There is a tape processing method in which the tape is formed using a water tape or the like, or an insertion method in which the connection is made using a sleeve cover, an insulating space insulating cylinder, etc.

Since the connection method uses fire, there is a risk of a fire, and there is a risk of damaging the cable insulation due to the heat of the pot. It requires a high degree of skill and management. '1. In addition, it is necessary to pull back the insulating cylinder onto the insulating rubber spacer and sleeve cover after connecting the conductors, and there is an r: +1 problem in terms of workability. On the other hand, recently, in order to save labor in power distribution work, a connection method that is simple and easy to work with is desired.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a connection structure that can eliminate the drawbacks of the conventional connection methods, and also allows a VC to be opened easily and quickly.

Hereinafter, the configuration of the present invention will be explained based on the accompanying drawings.

As shown in the figure, the structure of the cable part according to the present invention is that the conductor 2 is exposed from each cable 1 to be connected, the male terminal 3 is fixed to the tip of one conductor 2, and the other conductor 2 is
A female terminal 4 is solidly layered on the tip of the terminal, and both terminals 3 and 4 are fitted together.

A rubber bushing 5 and a heat-shrinkable tube 6 are inserted into the outer circumference of the cable 1 in advance prior to connection, and a leaf spring 8 and a couple insulation layer are placed around the thin copper 7 of the cable 1 exposed by stripping the steps. Spacer 1 around 9
Cover each with 0.

3. Spacer 10 and both male and female terminals on top A pin.
4 has a connection case 11.1 for each cable 1.
1' is temporarily attached to the 0 male terminal 3 side, and the case 11 is attached to the inner circumference of the metal case 12 with an outer semiconductive layer 13, an insulating layer 14, and an inner semiconductor layer 14 through an adhesive compound.
15, and each of these layers 13, 14, 15 is conductor molded with the metal case 12 described above. Further, the outer circumferential surface VC of the connection end 1 of the metal case 12 has a screw 1
6 is cut out, and a bag nut 17 is fitted into this. In addition, the external semiconductor layer 13 and the insulating layer 14 are formed to reach the connection end surface of the metal case 12, but the internal semiconductive layer 14 extends from the tip of the spacer 10 into the male terminal 3. A female terminal 4 and a connection case 11 on the female terminal side are formed on the four parts of the outer periphery of the tip of the male terminal 3.
The convex portion of the tip of
The other connection case 11' is connected to the metal case 12' through a bonding pad to the outer semiconductive layer 13', the insulation layer 114', and the inner half of the case 11', as in the case described above. Layer 15' is integrally molded.

Seven flange 78 is formed on the connection end side of metal case 12', and the aforementioned cap nut 17 is engaged with seven flange 18 to connect both connection cases 11 and 11'. Furthermore, the above-mentioned external semiconductor layer 11' is formed up to the end surface of the metal case 12'! +, but the insulating layer 14' and the internal semiconducting layer 15' (7f) have a convex part extending to the tip surface of the female terminal 4, and are placed on the four parts of the male end f-311111. .fa above
rt'M case 11' also connects cable 1 to cable 1 with heat shrink tube 6 as in the case described above. ! +1 shielded, and the heat sink tube 6' is also covered with the fold 9 of the bag nut 17,
This makes it waterproof.

Note that the fitting between the connection case 11 and the connection case 11' is as follows.
In the case of the figure, the four parts are shaped like b1jL to the male terminal 341+11.

Female terminal 491! Iv/-Convex part cedar plj, L s
At the same time when both female and male terminals 3.4 are mated, case 11.1
1', the concave part and the convex part are combined at the same time, but the above-mentioned four parts and the convex part are formed on the opposite side, that is, a convex part is formed in place of the male terminal 3, and a concave part is formed around the female terminal 4. As shown in ``2'', this invention connects the VC male terminal of one cable conductor to be connected, the female terminal to the other cable conductor, and solidifies the VC male terminal of the valley cable and the female terminal of the other cable conductor. An i''L contact connector is provided on the outer periphery of the female terminal, and the protrusion and recess that fit into the connection end surface of the valley connection case are of the shape 1jWL, so the ends of the cable are processed separately. By simply attaching the male and female terminals and each connection case, and then fitting them together, you can perform Ikrjc using the νIJ plug-in method with nine touches.

In addition, it is possible to firmly connect each sand case by simply tightening the bag nuts. Therefore, the construction time can be shortened and the construction time can be shortened, and the construction time can be shortened. It doesn't require advanced technology, so it's easy to use! The power ratio we share can be atrocious.
