Next, the ground wire 1 is shielded at a predetermined position on the shield layer 4. Wrap as many times as necessary. Furthermore, confirm that the temperature of the soldering iron 9 is appropriate, The ground wire 1 and the shielding layer 4 are connected by using the solder 8.

[0004]   As a technique that does not use solder, see Japanese Utility Model Publication No. 58-193813 and other publications. Although disclosed, all use metal bands to connect to the ground wire.

[0005]

[Problems to be solved by the device]

  In the former work technique, in the former case, solder is used to connect the ground wire 1 to the shield layer 4. Therefore, a skilled worker is required to continue, and when the soldering iron 9 is an electric type, an appropriate temperature is required. There was a problem that it was necessary to manage it.

[0006]   In addition, in the latter case of the conventional technology, various dimensions are adjusted according to the outer diameter of the cable shielding layer. There was a problem that it was difficult to connect the ground wire because it was necessary to prepare a legal thing .

[0007]   This invention was made in order to solve the above problems, using solder. First of all, to obtain a high-voltage cable termination connection device that can easily and securely connect the shield layer to the ground wire. aimed to.

[0008]

[Means for Solving the Problems]

  The high-voltage cable terminal connection device according to the present invention is provided with a shield layer for the high-voltage cable. The conductive metal band that surrounds and is crimped and held, and is integrated with this by a crimping action. It is equipped with a metal grip that holds the end of the ground wire. A flexible synthetic resin band that is locked by winding the shield layer of the cable and the inside Conductive metal band that is partly joined together and integrated with this, for crimping action It is provided with a metal grip for gripping the end of the ground wire.

[0009]

[Action]

  For the conductive metal band in this work, sandwich the shield layer and tighten it with screws. Or, it is connected to the shielding layer by tightening due to the clip property. Also metal Hold the end of the ground wire to the metal grip integrated with the band and crimp it. Allows the ground wire and the shielding layer to be connected through the conductive metal band without using solder. Are connected.

[0010]

【Example】

Example 1.   An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a ground wire 2 is an insulator, 3 is a semiconductive layer, 4 is a shielding layer, and 5 is a cable sheath. 6 is With the conductive metal band, the integrated metal grip 6a is formed on its extension line. ing. The metal grip 6a is substantially cylindrical and has a slit. 7 is a metal band 6 It is a mounting screw.

[0011]   Next, the operation will be described. Include the cable sheath 5, shield layer 4, and semi-conductive layer 3. Peel off each of the specified length. Next, the conductive metal band 6 is provided on the shielding layer 4 in a predetermined manner. Set to the position and tighten with screws 7. Further, connect the end of the ground wire 1 to conductive gold. Insert it into the metal grip 6a integrated with the metal band 6 and tighten it with a crimping tool. To do.

[0012]   Inserting the ground wire to the metal grip 6a and mounting work by crimping should be done with conductive metal. This is performed before or after attaching the band 6 to the shielding layer 4.

[0013]   FIG. 3 is a diagram in which the conductive metal band of the above embodiment is changed to a clip system. . In other words, fit a clip that has elasticity in the direction of diameter reduction at a predetermined location and connect the terminals. It is what I made. The metal grip 6a may be directed upward or downward. FIG. 4 shows the mounting situation.

[0014] Example 2.   FIG. 5 shows an embodiment corresponding to claim 2, in which the flexible synthetic resin band 6b is guided inside. The electro-conductive metal band 6 is integrally connected, and the metal grip 6 is exposed from the lower part of the metal band 6 6a is integrated. A holder is attached to one end of the flexible synthetic resin band 6b. There is a 6c, and the saw blade-shaped locking piece 6d provided at the other end is inserted into the holder 6c and tightened. It is in a locked state.

[0015]   FIG. 6 is a cross-sectional view of the attachment to the shielding layer, showing the locked state. is there. The metal band 6 may be at least partially inside the synthetic resin band 6b. Further, if the flexible synthetic resin band 6b is set to be long to some extent, an arbitrary outer diameter can be obtained. Applicable to cables that have.

[0016]

[Effect of device]

  As described above, according to this invention, the shielding layer of the high-voltage cable is surrounded and crimp-protected. The held conductive metal band and the end of the ground wire are integrated with this by the crimping action. Since it has a metal grip to hold, no soldering work is required The above connection is possible even if you are not a person, and it can be installed with a simple operation and the ground wire Does not come off.

[0017]   In addition, the present invention further includes various types of support by winding and locking a flexible synthetic work piece. It is applicable to IZ cable and prevents damage to the insulator during installation, By tightening the metal grip, all ground wires such as tin plating and annealed copper wires can be connected. .
