The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention. The same or similar reference numbers in the drawings identify the same or similar elements.

A wire clamp for wiring, as shown in fig. 1 to 5, comprises a body 1, a connecting hole 2 and a U-shaped connecting groove 3 are formed on the body 1, both ends of the connecting groove 3 penetrate through the body 1, one side of the connecting groove 3 is positioned in the middle of the body 1, the other side penetrates through the body 1, clamping grooves 4 are formed on two opposite inner side walls of the connecting groove 3, a connecting plate 5 is detachably arranged in the two clamping grooves 4, a first connecting screw 6 penetrates through the connecting plate 5 and is in threaded connection with the connecting plate 5, a first protruding portion 7 is arranged on the inner wall of one side of the connecting groove 3 facing the first connecting screw, a pressing plate 8 is further included, the pressing plate 8 is positioned at one end of the first connecting screw 6 close to the first protruding portion 7, and a yielding groove 9 facing the first protruding portion 7 is formed in the middle of the pressing plate 8, the body 1 is further provided with a second connecting screw rod 10 in a threaded connection mode, one end of the second connecting screw rod 10 is located outside the body 1, and the other end of the second connecting screw rod 10 is located in the connecting hole 2.

One side of the compression plate 8 close to the first bulge 7 is in a concave arc shape. One side of the pressure strip 8 close to the first connecting screw 6 is provided with a rotating column 11, and the first connecting screw 6 is provided with a rotating hole 12 which is matched with the rotating column 11 in a rotating way. The end of the rotating column 11 is dome-shaped. The connecting groove 3 is provided with a second protruding part 13 on the inner wall of one side of the first connecting screw rod, the second protruding part 13 is positioned on the side part of the pressing plate 8, and a set distance is reserved between the first protruding part 7 and the second protruding part 13.

The middle of one end of the second connecting screw 10 in the connecting hole 2 is provided with a dome-shaped stabilizing protrusion 14. One side of the connecting hole 2 opposite to the second connecting screw rod 10 is provided with two third protruding parts 15, the second connecting screw rod 10 is provided with two, and the two second connecting screw rods 10 are positioned between the two third protruding parts 15.

The both sides of connecting plate 5 all are provided with stabiliser 16, the both sides of stabiliser 16 all laminate in the inner wall of connecting groove 3.

The utility model provides a pair of distribution fastener when connecting two electric wires, at first all removes the apparent inoxidizing coating of the electric wire that original electric wire and needs to be connected, then with original connection of electric lines to spread groove 3, with newly-increased connection of electric lines to in connecting hole 2 (the connection order of the two can be adjusted at any time according to actual conditions) to realize the circular telegram of two electric wires. In which the original wire cannot be cut off and can be snapped directly into the connecting slot 3, but the newly added wire is usually free at one end and can be inserted into the connecting hole 2.

After the spread groove 3 is gone into to original electric wire card, go into joint groove 4 with connecting plate 5 card, the position of connecting plate 5 reachs suitable back, rotate first connecting screw 6, first connecting screw 6 compresses tightly pressure strip 8 on the electric wire, the electric wire can be contradicted on the inner wall of spread groove 3, also contradicted on first bellying 7 simultaneously, and let groove 9 make the suppression electric wire that pressure strip 8 can step forward, and make after the electric wire warp, better laminating is on the inner wall of spread groove 3, it is better to the conduction effect of electric energy. Furthermore, since the electric wire is deformed at the first protruding portion 7, the resistance between the electric wire and the inner wall of the connecting groove 3 is increased, and the electric wire and the connecting groove cannot slide relatively, so that the stability of connecting the two electric wires is improved. In practical use, a protective sleeve made of an insulating material is arranged outside the wiring clamp, the shape of the protective sleeve is also suitable for the structure of the embodiment and is conventional, and excessive limitation and repeated description are omitted.

The pressure strip 8 is arc-shaped, so that the pressure strip can be better attached to the outer wall of the electric wire, the pressure effect on the electric wire is better, the pressure area is increased, the electric wire is prevented from being deformed, the contact area between the pressure strip and the electric wire is increased, and the resistance of conducting electric energy is smaller. Wherein the pressing plate 8 is rotatably connected to the first connecting screw 6, so that the pressing plate 8 can be maintained in a state of being attached to the exterior of the electric wire regardless of the rotation of the first connecting screw 6. Meanwhile, a certain resistance is formed between the rotating column 11 and the rotating hole 12, so that in actual use, one connection can be kept between the pressing plate 8 and the first connecting screw 6, the pressing plate 8 does not need to fall off when no external force exists, and the operation convenience is improved. And the top of the rotary post 11 is dome-shaped so as to be coupled with the pressing plate 8 after the first coupling screw 6 passes through the coupling plate 5.

The second convex part 13 is positioned at the side part of the pressing plate 8, so that the electric wire between the pressing plate 8 and the second convex part 13 can also be deformed, thereby further improving the stability of the connection between the electric wire and the body 1; wherein as shown in fig. 2, the first and

second protrusions

7 and 13 are located at both sides of the coupling groove 3, while the escape groove 9 is also opened at one side of the pressing plate 8. Similarly, the electric wire (i.e. the newly added electric wire) between the third protruding portion 15 and the second connecting screw 10 is also deformed and then attached to the inner wall of the connecting hole 2, so that the static friction force applied to the electric wire is also increased, the electric wire and the body 1 can be well prevented from moving relatively, and the connection stability is improved. Meanwhile, the stable bulge 14 can drive the wire to deform, so that the connection stability between the wire and the stable bulge is improved (the wire cannot be broken); or some of the wires may be multi-stranded, so that the stabilizing projections 14 can also be snapped between adjacent thin wires.

The both sides of connecting plate 5 have stabilizer 16, so stabilizer 16 can contradict on two inner walls in chucking groove to improve connecting plate 5's atress size, played the guard action to connecting plate 5, guaranteed connection stability.

It should be noted that, in the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
