Description

Clamp for wire connection

technical field

The utility model relates to a wire connection technology, in particular to a wire clip for wire connection.

Background technique

It is very important to ensure the safe and stable operation of the power grid in today's society. The poor connection of wires has brought many troubles to people, such as shunting. At present, most places use direct winding of shunt wires on the main line. This method often leads to weak wiring and disconnection, which brings certain losses to users and a lot of work for maintenance and emergency repair personnel. The existing wire clamps are unevenly loaded on one side and easily deformed on one side. When the nut is tightened, they will slide to the left and right sides. It takes multiple adjustments to align, which increases the difficulty of operation. Moreover, the existing wire clamps can only hold fixed specifications. The trunk line cannot be used universally for trunk lines of different sizes, and many existing conductors are non-marked lines. Not all trunk lines are of the same size, so it is necessary to choose different existing clamps according to different sizes of trunk lines, which is troublesome to operate. It is inconvenient to use, and the clamping of the shunt line is not firm enough, and it will loosen after a long time of use. The existing wire clips do not have an insulating shell, or the structure of the insulating shell is too complicated, the cost is high, or it is not convenient to use. Some need to clamp the wire with the wire clip, and then assemble the insulating shell on the wire clip, which is inconvenient to use and difficult to use. Conducive to aerial work, such as patent No. 201320389563.5 named cable clamp with insulating shell, patent No. 201320468155.9 named Chinese patent of cable clamp with insulating shell, cable clamp (connecting clamp) and insulating shell, insulating shell Both include insulated half-shells, which can open and close the insulating shell cover. The insulating shell cover and the cable clamp are generally separate structures. When in use, first clamp the wire with the cable clamp, and then set the insulating shell to the cable. On the cable clamp, because the cable clamp is conductive, it is a live operation at this time. The construction personnel may hold the wire with one hand and install the cable clamp with the other hand, which is easy to get an electric shock and the operation safety is poor. Generally, the clamping operation is carried out in the air. In the air, it is necessary to carry the cable clamp and the insulating shell at the same time, and then set them on the cable line one by one. The high-altitude operation takes a long time, the construction safety is reduced, the wiring operation is troublesome, and the structure is usually more complicated.
