[0002] A busbar clamp is a hardware fitting used to fix electric wires or cables. It is very common in industrial production to ensure the stability and safety of electric wires or cables. In the process of use, in order to reduce the impact and damage to the busbar during operation, the usual method is to use rubber or silicone gaskets at the part where the busbar clamp contacts the busbar. These materials have certain elasticity and buffering performance, which can reduce the impact during clamping. However, in actual use, the rubber gasket may have dimensional changes after long-term use, which may affect its fitting accuracy with the mating parts and reduce the clamping effect during subsequent use. Summary of the Utility Model
[0003] Aiming at the above problems, the purpose of the utility model is to provide a split busbar clamp to solve the problem that the rubber gasket may have dimensional changes after long-term use in actual use, which may affect its fitting accuracy with the mating parts and reduce the clamping effect during subsequent use.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a split busbar clamp, including an installation cross-tube, an adjusting threaded rod and an adjusting double-headed screw. Both ends of the installation cross-tube are installed with end baffles I through bolts, and a buffer leaf spring is installed inside the installation cross-tube. A clamping plate is installed inside the installation cross-tube. An insulating pad block is inserted and installed inside the clamping plate. An end baffle II is installed outside the clamping plate. A guiding insertion rod is installed below the clamping plate, and the end of the guiding insertion rod away from the clamping plate is inserted and installed with a guiding sleeve. A buffer spring is sleeved on the lower half of the guiding sleeve. The adjusting threaded rod is installed below the clamping plate, and limiting nuts are installed at equal intervals on the adjusting threaded rod.
[0005] The beneficial effect of the utility model is: during the installation process, the clamping plate will squeeze the buffer leaf spring when pressed, and the clamping plate drives the guiding insertion rod to squeeze the buffer spring. During the squeezing process, the guiding sleeve guides the guiding insertion rod. By using this method, the impact during clamping can be reduced, and dimensional changes can be effectively avoided during subsequent use to ensure the clamping effect.
[0006] For the convenience of adjusting the distance between the clamping plates:
[0007] As a further improvement of the above technical solution: a keyway through-hole is opened below the clamping plate.
[0008] The beneficial effects of this improvement are as follows: During use, when adjusting the threaded rod, it can pass through the clamping plate more conveniently and quickly through the keyway through-hole. Then, the position of each clamping plate can be limited by using the limit nut, which is convenient for adjusting the distance between the clamping plates.

[0014] The beneficial effects of this improvement are as follows: After the insulating spacer is installed on the clamping plate, the end baffle II is installed on the outside of the clamping plate by bolts. The end baffle II symmetrically arranged about the midline can firmly and reliably limit both ends of the insulating spacer.
[0015] To reduce the impact on the busbar during installation:
[0016] As a further improvement of the above technical solution: The guiding insertion rod is symmetrically arranged about the midline of the clamping plate.
[0017] The beneficial effects of this improvement are as follows: The guiding insertion rod symmetrically arranged about the midline can cooperate with the guiding sleeve and the buffer spring to buffer the clamping plate, absorb the impact during installation, and ensure the clamping effect of the device on the busbar.
[0018] To facilitate the rotation of the limit nut:
[0019] As a further improvement of the above technical solution: Convex blocks are equidistantly arranged on the outer side of the limit nut.
[0020] The beneficial effects of this improvement are as follows: The protrusions can increase the friction between the limit nut and the palm, which can facilitate the user to rotate the limit nut to adjust the position of the limit nut, and further facilitate the adjustment of the position of the clamping plate.
[0021] To fix the installation cross-tube:
[0022] As a further improvement of the above technical solution: The cross-section of the adjusting double-headed screw is H-shaped.

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to the drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.
[0034] Such as Figures 1-5As shown in the figure, the split busbar clamp includes an installation cross tube 1, an adjustment threaded rod 3 and an adjustment double-headed screw rod 13. Both ends of the installation cross tube 1 are installed with end head baffles one 11 through bolts, and a buffer leaf spring 12 is installed inside the installation cross tube 1. A clamping plate 2 is installed inside the installation cross tube 1. An insulating cushion block 21 is inserted and installed inside the clamping plate 2. An end head baffle two 22 is installed on the outside of the clamping plate 2. A guide insertion rod 23 is installed below the clamping plate 2, and one end of the guide insertion rod 23 away from the clamping plate 2 is inserted and installed with a guide sleeve 24. A buffer spring 25 is sleeved on the lower half of the guide sleeve 24. The adjustment threaded rod 3 is installed below the clamping plate 2, and limit nuts 31 are installed at equal intervals on the adjustment threaded rod 3. During the installation process, when the clamping plate 2 is pressed, it will squeeze the buffer leaf spring 12, and the clamping plate 2 drives the guide insertion rod 23 to squeeze the buffer spring 25. During the squeezing process, the guide sleeve 24 guides the guide insertion rod 23. Using this method can reduce the impact during clamping and effectively avoid size changes during subsequent use, ensuring the clamping effect. A keyway through hole is opened below the clamping plate 2. During use, the adjustment threaded rod 3 can pass through the clamping plate 2 more conveniently and quickly through the keyway through hole. Then, the limit nuts 31 can be used to limit the positions of the clamping plates 2, thereby facilitating the adjustment of the distance between the clamping plates 2. A guide chute is provided at the position of the clamping plate 2 close to the insulating cushion block 21, and the cross section of the insulating cushion block 21 is U-shaped. The insulating cushion block 21 can be guided and limited through the guide chute, thereby facilitating the connection between the insulating cushion block 21 and the clamping plate 2. The U-shaped setting can facilitate the clamping plate 2 to clamp the busbar. The end head baffle two 22 is fixed to the clamping plate 2 through bolts, and the end head baffle two 22 is symmetrically arranged about the center line of the clamping plate 2. After the insulating cushion block 21 is installed on the clamping plate 2, the end head baffle two 22 is installed on the outside of the clamping plate 2 using bolts. The end head baffle two 22 arranged symmetrically about the center line can firmly and reliably limit both ends of the insulating cushion block 21. The guide insertion rod 23 is symmetrically arranged about the center line of the clamping plate 2. The guide insertion rod 23 arranged symmetrically about the center line can cooperate with the guide sleeve 24 and the buffer spring 25 to buffer the clamping plate 2 and absorb the impact during installation, ensuring the clamping effect of the device on the busbar. Convex blocks are arranged at equal intervals on the outside of the limit nut 31. The protrusions can increase the friction between the limit nut 31 and the palm, thereby facilitating the user to rotate the limit nut 31 to adjust the position of the limit nut 31, and further facilitating the adjustment of the position of the clamping plate 2. The cross section of the adjustment double-headed screw rod 13 is H-shaped. The H-shaped setting can prevent interference between the adjustment double-headed screw rod 13 and the adjustment threaded rod 3 and facilitate the installation of the adjustment double-headed screw rod 13. Through holes are opened on the end head baffle one 11. The through holes installed on the end head baffle one 11 can facilitate the end head baffle one 11 to cooperate with bolts to fix the position of the adjustment threaded rod 3.
[0035] The working principle of the utility model is as follows: when using this device, insert the insulating spacer block 21 onto the clamping plate 2, and then use the end baffle two 22 and bolts to install the end baffle two 22 on the clamping plate 2 to limit the position of the insulating spacer block 21. Use the adjusting screw rod 3 and the limit nut 31 to adjust the clamping plate 2 to a suitable position, and then insert the clamping plate 2 into the interior of the installation cross tube 1. Then use bolts, the adjusting screw rod 3 and the end baffle one 11 to limit both ends of the installation cross tube 1 to fix the position of the busbar. After the limitation is completed, use the adjusting screw rod 3 to fixedly adjust the spacing of the installation cross tube 1 to complete the clamping and fixing of the busbar. During the installation process, when the clamping plate 2 is pressed, it will squeeze the buffer leaf spring 12, and the clamping plate 2 drives the guiding insertion rod 23 to squeeze the buffer spring 25. During the squeezing process, the guiding sleeve 24 guides the guiding insertion rod 23. By adopting this method, the impact during clamping can be reduced, and the size change can be effectively avoided during subsequent use to ensure the clamping effect.
