Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric bridge clamps, in particular to an electric bridge clamp for producing cables and wires. Background Art
[0002] According to national standards, during the production of metal conductors, it is necessary to measure the DC resistance of the core of metal conductors and wires and cables. Generally, the four-terminal measurement method is used to measure the resistance of the sample. This test is usually performed using a bridge resistance tester to measure the conductor resistance value of a certain length of wire or cable. Usually, a bridge clamp is used to clamp the wire and energize it. However, during the experiment, if the wire or cable is long, the middle position, especially the cable, sags due to its own gravity, making the tested cable or wire not straight, which will affect the accuracy of the test.

[0005] Preferably, the bidirectional screw is connected to the support box via a bearing, an inner ring of the bearing is interference fit with the bidirectional screw, and an outer ring of the bearing is fixedly connected to the support box.
[0006] Preferably, a handle is provided at one end of the bidirectional screw.
[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can support the cable through the support structure arranged on the front and rear sides of the bridge clamp, and the two movable seats can be moved in a straight line toward or away from each other through the arrangement of the bidirectional screw in the support structure, thereby ensuring that cables of different lengths can be stably supported and effectively preventing the cables from sagging and twisting. The height of the support seat can be adjusted through the arrangement of the cylinder in the support structure to ensure support for cables of different specifications, with strong flexibility.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] See also Figure 1-3 The utility model provides an electric bridge clamp for cable and wire production, including a clamp body 1, two supporting structures 2 are arranged on the front and rear sides of the clamp body 1, the supporting structure 2 includes a supporting box 21, a bidirectional screw 22, a limiting rod 23, two moving seats 24, two cylinders 25 and two supporting seats 26, the supporting box 21 is arranged on the front side of the clamp body 1, and the top of the supporting box 21 is opened, the bidirectional screw 22 is rotatably connected to the left and right sides of the supporting box 21 respectively, the limiting rod 23 is arranged between the left and right sides of the supporting box 21, the two moving seats 24 are movably connected to the left and right sides of the bidirectional screw 22 and the limiting rod 23 respectively, the two cylinders 25 are respectively arranged on the top of the two moving seats 24, and the two supporting seats 26 are respectively arranged at the driving ends of the two cylinders 25.
[0014] Specifically, the bidirectional screw 22 is connected to the support box 21 via a bearing, the inner ring of the bearing is interference fit with the bidirectional screw 22 , and the outer ring of the bearing is fixedly connected to the support box 21 .
[0015] Specifically, a handle 3 is provided at one end of the bidirectional screw rod 22 .
[0016] Working principle: When it is necessary to fix cables and wires of different lengths or diameters, the operator can rotate the handle 3 of the bidirectional screw 22. Due to the limiting effect of the limit rod 23 on the moving seat 24, when the screw rotates, the two moving seats 24 will move linearly toward or away from each other, thereby adjusting the distance between the two support seats 26. This design enables the clamp body 1 to adapt to cables and wires of different lengths, improving the versatility and flexibility of the clamp. After adjusting the distance between the support seats 26, the operator will start the cylinder 25, and the driving end of the cylinder 25 is connected to the support seat 26. When the cylinder 25 extends, it will push the support seat 26 up until the support seat 26 contacts the cable and wire and provides stable support for it. The synchronous operation of the two cylinders 25 ensures that the cable and wire can be evenly supported on both the front and rear sides, effectively avoiding sagging or twisting caused by the cable and wire's own gravity.
[0017] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
