Description

A wire clip for connecting fire in live work

Technical field:

The utility model relates to a wire clip, in particular to a wire clip used for power distribution overhead lines and used for fire connection in live work.

Background technique:

Live work on power distribution overhead lines can not only avoid power outages for users, but also has more flexible working hours. With the continuous improvement of social and economic requirements for power supply reliability, the live work items and scope of power distribution lines have expanded year by year, but live work on power distribution overhead lines During work, when the operator installs the branch line with live electricity, when the wiring wire originally used for power outage work is clamped at the end of the fixed branch line, not only the live working method of the insulating rod is not applicable, but also because the power outage and live work are different. The original wiring During the direct live working process, the clamp is unstable in operation and often falls off. After the original wiring clamp is installed, the bending shape of the end of the branch line needs to be adjusted, which increases the unsafety of live work. In order to change the occurrence of similar situations, it is urgent to develop a clamp that is not only suitable for direct live work, but also suitable for the live action of insulating rods, so as to improve the scope and efficiency of live work in power distribution, ensure the quality of equipment installation, and ensure the quality of power distribution overhead lines. The safety of live work.

Utility model content:

The purpose of this utility model is to overcome the deficiencies of the above-mentioned prior art and provide a simple structure, safe and reliable, flexible adjustment, stable installation, wide application range, improve the efficiency of live work, and ensure the safety of live work. wire clamp.

The purpose of this utility model can be achieved through the following measures: a wire clamp for live work, characterized in that it includes a fixed end, the fixed end is formed by connecting a fixed hook and a fixed end seat, the fixed end The upper part of the seat is movably connected to the wire end pressing plate by the fixing bolt, and the bottom of the fixed end seat is threadedly connected to the fastening screw, one end of the fastening screw is connected to the fastening end, and the other end is connected to the fastening bolt.

Compared with the prior art, the utility model can produce the following positive effects: the utility model can be operated with an insulating operating rod with a head, and can also be operated with a common socket wrench.

And the end of the lead wire of the branch line does not need to adjust the bending shape, it only needs to pass the wire head pressure plate and the fixed end

The head bolts are connected and fixed by compression, so that the connecting leads of the overhead line can be naturally drooped in a hanging chain shape, reducing the time of live work, improving the efficiency of live work, ensuring the safety of live work, and ensuring the convenience and quality of equipment installation.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

The specific embodiment: the specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing:

Embodiment: A wire clip for connecting to fire in live work (see Figure 1), made of copper material, it includes a fixed terminal 1, the fixed terminal 1 is composed of a fixed hook 1-1 and a fixed terminal seat 1 -2 connection structure, the upper part of the fixed end seat 1-2 is movably connected to the wire head pressure plate 3 through the fixed bolt 2, the lower part of the fixed end seat 1-2 is threaded to the fastening screw 6, and one end of the fastening screw 6 is connected to the fastening end Head 5, the other end is connected with fastening bolt 4.

When in use, press and fix the end of the lead wire between the wire head pressure plate 3 and the fixed end seat 1-2 through the fixing bolt 2, and connect the fixed hook 1-1 of the fixed end 1 through the insulating operating rod or the direct operation method. Hook on the overhead live line, and drive the fastening screw 6 by rotating the fastening bolt 4 so that the fastening end 5 and the fixed hook 1-1 are fixed on the overhead live line to realize fire connection, so that the connecting lead wire of the overhead line becomes a hanging chain The shape is naturally drooping, the appearance is beautiful, and the working efficiency and safety are improved. The fastening bolt 4 can be operated with a common adjustable wrench or a socket wrench, and can also be operated with an insulating operating rod with a head.

Claims (1)

1. one kind is used for the wire clamp that live line working is started to exchange fire, it is characterized in that it comprises fixedly termination (1), fixedly termination (1) is connected and composed by stay hook (1-1) and stiff end headstock (1-2), the top of stiff end headstock (1-2) flexibly connects the end of a thread pressing plate (3) by set bolt (2), the lower thread of stiff end headstock (1-2) connects fastening screw (6), one end of fastening screw (6) connects fastening termination (5), and the other end connects fastening bolt (4).
