Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in FIG. 1 to FIG. 3 , the present invention provides a wiring clip, which includes a main line fixing end 10 and an electric meter terminal 20 , and a main line fixing slot 11 for hanging the main line is opened on the front of the main line fixing end 10 . , the meter terminal 20 is connected to the back of the main wire fixing terminal 10, and a number of fixing channels 21 are opened on the front side of the electricity meter terminal 20 which are connected with the main wire fixing groove 11. The lower part of the electricity meter terminal 20 The surface is provided with a wiring inlet 22 that communicates with the fixing line channel 21, the meter wire extends into the fixing line channel 21 along the wiring inlet 22, and the interior of the fixing line channel 21 is provided with a fixing groove 11 for the meter line and the main line. A conductive member that is electrically connected to the main line inside.

In this embodiment, the wiring principle of the meter wire and the main wire is as follows: the main wire fixed end 10 is hung on the main wire of the low-voltage line through the main wire fixing slot 11 , and the meter wire can move upward along the wiring inlet 22 and extend into the fixing wire channel 21 , the main line and the meter line are respectively connected by the internal conductive parts of the fixing line channel 21. Due to the conductive effect of the conductive parts, the electrical connection between the main line and the meter line is realized. The connection between the meter wire and the main wire; compared with the prior art, the entire terminal clip body is designed with conductive material to realize the connection between the main wire and the electric meter wire. There is no need to use screws to fix it, and it also avoids the problems of corrosion and loosening that may occur when the screws are exposed for a long time.

Further, in this embodiment, the specific structure of the conductive member is as follows: the conductive member includes a conductive tube 23 that penetrates the interior of the wire fixing channel 21, and the conductive tube 23 is provided with a wire clamping hole 231, and the conductive tube 23 is provided with a wire clamping hole 231. One end of the tube 23 extends into the main line fixing slot 11 and is connected with an electrical contact piece 24 , and the other end of the conductive tube 23 extends out of the meter terminal 20 and is connected with an elastic expansion piece 25 , which is driven by pressing the elastic expansion piece 25 The conductive tube 23 moves to one end of the main wire fixing slot 11 and makes the wire clamping hole 231 communicate with the wire inlet 22 .

The above-mentioned electrical contact piece 24 includes a conductive block 241 , and the conductive block 241 and the conductive tube 23 are connected by a conductive spring 242 .

The above-mentioned elastic retractable member 25 includes an insulating pressing block 251 connected to the end of the conductive tube 23. A retractable spring 252 is connected between the insulating pressing block 251 and the outer surface of the meter terminal 20, and the retractable spring 252 is sleeved on the outer surface of the meter terminal 20. The outside of the conductive tube 23 .

Based on the existing structure of the above-mentioned conductive member, the specific operation process of the conductive member connecting the main wire and the meter wire is as follows:

In step 1, the main line is extended inward along the opening of the main line fixing groove 11 to realize the hooking of the main line. Here, the main line fixing groove 11 is a structure similar to a hook. In order to prevent the main line from slipping from the opening of the main line fixing groove 11 A cover plate 12 for closing the opening of the main line fixing slot 11 is provided on the front of the main line fixing end 10 , one end of the cover plate 12 is hinged with the main line fixing end 10 , and the other end of the cover plate 12 is buckled It is movably connected with the fixed end 10 of the main line, and the cover plate 12 is fastened after the main line is hooked up;

Step 2: Extend the meter wire upward along the wiring inlet 22 and into the fixing wire channel 21, press the insulating pressing block 251 to deform the telescopic spring 252, and move the conductive tube 23 to one end of the main wire fixing groove 11 until the clip on the conductive tube 23. The wire hole 231 is aligned and communicated with the wiring inlet 22. At this time, the meter wire continues to extend into the inside of the conductive tube 23 and pass through the wire clamping hole 231 at the other end, releasing the pressing force of the insulating pressing block 251, and the wire clamping hole 231 and the wiring inlet 22 act to clamp the meter wire at the same time, that is, the connection between the meter wire and the conductive tube is completed;

During this process, when the conductive tube 23 moves toward one end of the main wire fixing groove 11 , the conductive block 241 is driven to contact and squeeze the main wire inside the main wire fixing groove 11 , which further drives the conductive spring 242 to shrink. After the action, the conductive tube 23 moves a little distance in the opposite direction of the main line fixing groove 11, the conductive spring 242 is slightly stretched for a certain distance, and the conductive block 241 always squeezes the main line. The conductive tube is also connected, so the connection between the main line and the meter line is realized;

The third step, for the connection of multiple meter lines, repeat the second step.

In the above operation process, in order to make the connection between the conductive block 241 and the main line more closely, and to avoid poor electrical conductivity due to insufficient contact, the conductive block 241 is in the shape of an arc block, and the inner part of the conductive block 241 A comb-shaped opening 243 is provided on the side, through which the main wire can be extended into the interior of the wire, and the contact area is larger.

One end of the conductive tube 23 protrudes from the meter terminal 20 and is connected with a spring expansion member 25. In order to avoid the electric shock accident caused by the operator accidentally touching the conductive tube 23, the outer surface of the expansion spring 252 can be covered with a layer of insulating protective cover , The spring is generally a metal structure, and the insulating protective sleeve is arranged to make the spring non-conductive. Therefore, the telescopic spring sleeved outside the conductive tube 23 acts as an external protection.

In addition, during the wiring operation of the electric meter wire, it is necessary to strip off the insulating layer at the end of the wire, so that the inner metal wire is in contact with the conductive tube 23, which increases the operation steps. As shown in the figure, by arranging the serrated piercing edge 232 at the edge of the wire clamping hole 231, when the electric meter wire is clamped in the wire clamping hole 231, the serrated piercing edge 232 at the edge directly cuts into the interior of the insulating layer and is Wire contact, eliminating the trouble of stripping the insulation.
