After adopting the connection structure of the utility model, it can effectively eliminate the material waste caused by remaking the flexible cable connection terminal, greatly shorten the working time, and the round body end in the connection structure can be directly connected with the existing standard special-shaped clamp, It can ensure the connection with overhead lines of different wire diameters, and increases the contact area of the conductor, making the connection more reliable, safe and fast.

Description

Connection structure between flexible cable and overhead line

technical field

The utility model relates to a connection structure between a flexible cable and an overhead line.

Background technique

When the distribution network implements bypass non-stop operation, it is necessary to connect the bypass flexible cable to the overhead line. The existing flexible cable terminals commonly used at present are not suitable for connecting with overhead lines of different wire diameters, and remaking joints according to the actual operation of each operation not only causes waste of flexible cables but also increases working time.

Utility model content

The purpose of the utility model is to provide a low-cost, portable, easy-to-use, firm and reliable connection structure between a flexible cable and an overhead line.

A connection structure between a flexible cable and an overhead line, which is special in that it includes an overhead line, a section of bare wire is arranged on the overhead line, and a special-shaped wire clip is clamped at one end of the bare wire. The other end of the wire is clamped and installed on one end of the L-shaped copper rod, and the other end of the L-shaped copper rod is connected with the nose terminal of the flexible cable through a fastener.

One end of the L-shaped copper rod is a cylinder and the cross-section of the other end is a rectangle.

The other end of the L-shaped copper rod is provided with a mounting hole, and the nose terminal of the flexible cable is also provided with a mounting hole. The fastener connects the L-shaped copper rod and the flexible cable through the above two mounting holes. The nose terminals are connected in one piece.

After adopting the connection structure of the present utility model, the material waste caused by remaking the flexible cable connection terminal can be effectively eliminated, and the working time can be greatly shortened, and the round body end in the connection structure can be directly connected with the existing standard special-shaped clamp, It can ensure the connection with overhead lines of different wire diameters, and increases the contact area of the conductor, making the connection more reliable, safe and fast.

Accompanying drawing 2 is the schematic diagram of the use state of the utility model.

Detailed ways

As shown in Figures 1 and 2, the utility model is a connection structure between a flexible cable and an overhead line, including an overhead line, on which a section of bare wire 1 is arranged, and a special-shaped clamp 2 (W-type double hole , can clamp two wires at the same time), one end of the special-shaped wire clamp 2 is clamped and installed on the bare wire 1 and the other end is clamped and installed on one end of the L-shaped copper rod 3, the L-shaped copper rod 3 The other end is connected with the nose terminal 4 of the flexible cable through a fastener.

Wherein one end of the L-shaped copper rod 3 is a cylinder and the cross-section of the other end is a rectangle (or a flattened cylinder) with an aspect ratio of 5:1, and the other end of the L-shaped copper rod 3 is provided with a mounting There are also installation holes on the nose terminal 4 of the flexible cable. The fasteners (such as bolts and nuts) can connect the other end of the L-shaped copper rod 3 to the substantially rectangular parallelepiped through the above two installation holes. The nose terminal 4 of the flexible cable is connected as a whole (face-to-face contact between the two), thereby realizing a reliable and fast conductive connection between the flexible cable and the overhead line.
