Description

High current wire connecting member

technical field

The utility model relates to a large current wire connecting component .

Background technique

The connection of electrical equipment has long been the weak link in the power system. When the power load is too large, the connection point often has the problem of heating and burning out the equipment due to excessive contact resistance, causing fires and causing major safety hazards. The existing method mainly has the following problems: the contact area of the electrical equipment is small; the mechanical stability is poor; and the construction process is not simple. Any one of the above three problems can lead to the other two problems. There have been many researches and explorers on this problem for many years, but judging from the current situation, the problem has not been fundamentally solved. the

Utility model content

The purpose of the utility model is to provide a high-current wire connecting member with large contact area, good mechanical stability, convenient use and simple operation. the

The high-current wire connection member provided by the utility model includes a lug, and an intermediate connector connected with the lug, the intermediate connector is an internal threaded tube, and the internal threaded tube has a normal thread segment and a There is a main wrench position on the outer wall of the internally threaded pipe; the terminal lug includes a non-threaded pipe section and a screw section, the screw section is matched with the internal thread of the intermediate connector, and there is a Auxiliary wrench position. the

As a preferred mode of the present utility model, the shape of the intermediate connector is in the shape of a hexagonal column, all of which are used as the main wrench positions. The shape of the intermediate connector can also be that the middle section is in the shape of a hexagonal prism, and the two sides are cylindrical, and the position in the shape of the hexagonal prism is the main wrench position. In order to ensure a stable connection between the terminal lug and the intermediate connector, the screw section of the terminal lug is equipped with a parallel cap. the

Compared with the prior art, the utility model has the following advantages:

1. The contact surface at the joint increases;

2. Save the equipment clamps for transitional connections, reducing the point of failure;

3. The mechanical reliability of the connection is good, which can effectively reduce the influence of electric power on the connection;

4. The connection is easy to remove, and the operation process is simplified.

The utility model can be used for the connection of non-tension wires, the connection of wires and electrical equipment, and the connection between electrical equipment. the

FIG. 2 is an assembly view of the structure shown in FIG. 1 . the

Fig. 3 is a schematic structural view of the second embodiment of the utility model. the

Detailed ways

Embodiment 1: It can be seen from Fig. 1 and Fig. 2 that the utility model has an intermediate connector 1 and a lug 2, the intermediate connector 1 is an internally threaded pipe, and the pipe has a normal thread segment 11 and a reverse thread segment 12, The shape of the intermediate connector 1 is in the shape of a hexagonal column, and any position can be used as the wrench position 13, which provides convenience for actual operation. The terminal lug 2 includes an unthreaded pipe section 21 and a screw section 22. The screw thread on the screw section matches the intermediate connector 1, and there is a cap 23 on the screw section. The unthreaded pipe section is a hollow pipe section, which is mainly used for insertion Press the wire to be connected, and the auxiliary wrench position 24 is between the unthreaded pipe section and the threaded section. the

The utility model can be used for conductive connection in various working conditions:

For example, it can be used for the connection of non-tension wires. In this case, two lugs should be used. There are two methods of connection operation: one is to insert a wire into the unthreaded pipe section of a lug, and fix it by crimping; the other One wire is inserted into the unthreaded pipe section of the other terminal lug, fixed by crimping connection, and then the intermediate connector 1 is threadedly connected with the two terminal lugs, and tightened with the parallel cap 23 on the terminal lug screw section to complete the connection between the two wires. connection between. In another way, the two lugs can be connected to the middle connector first, and then the wires can be inserted into the terminals and pressed tightly to complete the connection between the two wires. When dismantling, loosen the joint cap, turn the intermediate connector 1 through the wrench position 13, and the connecting wire nose can withdraw from the connection at the same time, and the dismantling work is completed.

Another example can be used for the connection of wires and electrical equipment. In this case, the terminals of the electrical equipment should have external threads, and the wires should be inserted into the threadless tube inserted into the wiring lug for firm crimping, and then one end of the intermediate connector is connected to the wiring lug. The other end is connected to the terminal of the electrical equipment to complete the connection between the wire and the electrical equipment. The removal method is the same as above, loosen the cap, and then turn the middle connector to exit the connection between the equipment and the wire. the

It can then be used for electrical connection between equipment and equipment. In this case two lugs 2 and two intermediate connectors 1 are used. Both devices should have threaded terminal posts. Connect the two terminal lugs with wires. One end of the two intermediate connectors is connected to the terminal lugs and the other end is connected to the equipment to complete the electrical connection between the two devices. When removing the connection between the two devices, loosen the union cap, and then turn the middle connector to complete the removal work.                       

Embodiment 2: FIG. 3 reflects the structure of Embodiment 2. This embodiment also has an intermediate connector and a lug like the embodiment. The difference is that the wrench on the outer wall of the intermediate connector 1 is located in the middle, and the two sides are cylindrical. This structure is more economical than Embodiment 1 in terms of materials. Copper acts as a precious metal, and the cost saving is more obvious.

In a word, the utility model is easy to operate, safe and reliable, and convenient to connect and dismantle. the
