Description

  The present invention relates to an underline connector that is installed at a branch portion between a high voltage line installed between utility poles and a draw line branched from the high voltage line.

  Usually, the underline drawn into the transformer is branched from the high-voltage line installed between the utility poles. For this part, the underline is formed so that the high-voltage line and the underline can be locked together. Connector is installed. It is recommended that the work for installing the underline connector is performed by indirect hot wire work from the viewpoint of safety and the like. Indirect hot-line work is work that is performed without using an insulating tool (such as Yatco, a bolt tightening tool, a shared operation rod) without the worker directly touching the live part. The work that is performed by directly touching the charging part while wearing a body etc. is called direct hot line work).

As described above, the underline connector is desired to have a structure that can be installed by an indirect hot wire operation, and there are the following conventional techniques for that purpose. As shown in FIG. 11, the underline connector according to this prior art is configured to have a movable connector member 200 and a fixed connector member 201, and each connector member 200, 201 holds a high-voltage line 203. A semicircular arc-shaped recess 204 is formed, and both connector members 200 and 201 are urged in the direction of tightening the high-voltage line 203 sandwiched between the recesses 204 by the action of an elastic body 205 such as a coil spring. The connector members 200 and 201 have holes through which the bolts 206 are inserted. After the high-voltage wire 203 is sandwiched between the recesses 204, the connector members 200 and 201 are tightened with the bolts 206 to pull the connector members 200 and 201. The underline connector is securely fixed to the high voltage line 203 (see Patent Document 1). When attaching the underline connector to the high-voltage line 203, the operated handle 202 provided on the fixed connector member 202 is held by a tool such as an insulating Yatco, and the high-voltage line 203 is fitted into the recess 204. In this manner, the entire underline connector is pressed against the high-voltage line 203 while resisting the urging force of the elastic body 205. Then, after the high voltage line 203 is fitted in the recess 204, the bolt 206 is tightened using an insulating ratchet bolt tightening tool or the like.

Yes. In this conventional structure, the tightening operation using the bolt 206 is necessary to obtain a sufficient fixing force, but the bolt tightening operation using the bolt tightening tool is difficult. Thus, the conventional structure has room for improvement in terms of workability and the like by indirect hot-line work.

At this time, since the cam does not rotate backward, the movement of the high-voltage line in the direction away from the space is restricted. Further, when it is desired to remove the underline connector from the high voltage line, the reverse rotation of the cam may be permitted by operating the release means. Thereby, even if it does not tighten with a volt | bolt like the past, the underline connector can be reliably and simply fixed to a high voltage line.

By moving upward and inward, the contact pressure between the high-voltage line and these wedge-shaped members increases, and the underline connector is firmly held by the high-voltage line. Also, when removing the underline connector from the high-voltage line, the wedge-shaped member is displaced downward and outward by its own weight by slightly pushing up the underline connector once, so that the wedge-shaped member and the high-voltage line come into contact with each other. Since the state is released, if the underline connector is pulled down, it can be removed from the high voltage line. As described above, also with this configuration, the underline connector can be reliably and easily fixed to the high-voltage line.
