Description

Technical Field

[0001] The utility model relates to the technical field of cable clamps, in particular to an insulating clamp for cable connection. Background Technique

[0002] A cable clamp refers to a metal accessory used to fix and protect cables. It is usually made of metal materials and is used to connect the conductor and insulator of the cable, including terminal clamps, branch clamps, connecting clamps, cable fixing clamps and cable protection clamps. Among them, the connecting clamp is mainly used for the connection point of the cable and plays an auxiliary connection role when connecting the conductor of one cable to the conductor of another cable.

[0003] The utility model with the existing authorization announcement number CN216903396U discloses an insulating cable clamp, which is provided with a locking part at the top of the first clamp and the second clamp. The locking part is matched with the first clamp and the second clamp in a clamping manner. Compared with the traditional fixed clamp, the locking part can be disassembled and installed conveniently and quickly without tools. At the same time, the locking part can enhance the connection strength between the first clamp and the second clamp, improve the tensile resistance, and reduce the probability of deformation and damage. The locking piece arranged on the locking part can adjust the clamping force on the cable by changing the interference fit depth with the first clamp and the second clamp, ensuring that the cable will not loosen.

[0004] Adopting the above technical solution, although it can be disassembled and installed conveniently and quickly, the above technical solution can only wrap and clamp part of the structure at the cable connection, lacking a stable clamping structure with good balance, resulting in the two sections of cables being easily detached due to external pulling or shaking.

[0005] Therefore, those skilled in the art provide an insulating clamp for cable connection to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to provide an insulating clamp for cable connection to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution:

[0008] An insulating clamp for cable connection includes a fixed shaft, a handle block is fixedly connected to the outer surface of the fixed shaft, and a stable clamping mechanism is arranged outside the fixed shaft;

[0009] The stable clamping mechanism includes two first arc-shaped clamping shells and two second arc-shaped clamping shells. Limiting blocks are fixedly connected to the outer surfaces of the two first arc-shaped clamping shells and the outer surfaces of the two second arc-shaped clamping shells. Two limiting cylinders are arranged on the outer side of the fixed shaft. A hand-twist adjusting bolt is threadedly connected to the inner wall of each first arc-shaped clamping shell. An adjusting block is slidably connected to the inside of each first arc-shaped clamping shell. An auxiliary bearing is fixedly connected to the inner wall of each adjusting block. A fixed rod is fixedly connected to the front surface of each adjusting block. A limiting rod is fixedly connected to the front surface of each second arc-shaped clamping shell. A limiting block is arranged on the outer side of each first arc-shaped clamping shell.

[0010] As a further solution of the present invention: The inner walls of the two first arc-shaped clamping shells and the inner walls of the two second arc-shaped clamping shells are all rotatably connected to the outer surface of the fixed shaft. The outer surface of each limiting cylinder is in contact with the inner wall of the limiting block. The inner ring of each auxiliary bearing is fixedly connected to the outer surface of the hand-twist adjusting bolt. The inner wall of each limiting block is rotatably connected to the outer surface of the fixed rod. The outer surface of the limiting rod is clamped in the inside of each limiting block. A first anti-slip pad is fixedly connected to the outer surface of the handle block. A number of identical first anti-slip convex columns are fixedly connected to both side surfaces of the first anti-slip pad.

[0011] As a further solution of the present invention: A first insulating anti-slip pad is fixedly connected to the inner wall of each first arc-shaped clamping shell. A second insulating anti-slip pad is fixedly connected to the inner wall of each second arc-shaped clamping shell.

[0012] As a further solution of the present invention: A hand-twist limiting bolt is threadedly connected to the inner wall of each limiting cylinder. The outer surface of each hand-twist limiting bolt is in contact with the outer surface of the limiting block.

[0013] As a further solution of the present invention: A limiting slider is fixedly connected to the upper surface and the bottom surface of each adjusting block. The outer surface of each limiting slider is slidably connected to the inside of the first arc-shaped clamping shell.

[0014] As a further solution of the present invention: A second anti-slip pad is fixedly connected to the outer surface of each hand-twist adjusting bolt. A number of identical second anti-slip convex columns are fixedly connected to the upper surface and the bottom surface of the second anti-slip pad.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model adopts the mutual cooperation of the fixed shaft, the handle block, the first arc-shaped clamp shell, the second arc-shaped clamp shell, the limit clamp block, the limit cylinder, the hand-tightening adjustment bolt, the adjustment block, the auxiliary bearing, the fixed rod, the limit rod and the limit block. The first arc-shaped clamp shell and the second arc-shaped clamp shell can rotate around the fixed shaft, and then the two groups of the first arc-shaped clamp shell and the second arc-shaped clamp shell can respectively wrap the two sections of cables that are pre-electrically connected and the connection parts are insulated and wrapped. The limit block can rotate around the fixed rod and then be clamped with the limit rod. The auxiliary bearing can separate the rotation and linear movement of the hand-tightening adjustment bolt. Move, and then twist the hand-tightening adjustment bolt to make the fixing rod move away from the limit rod, thereby increasing the clamping stability of the limit block and the limit rod and the stability of the first arc-shaped clamp shell and the second arc-shaped clamp shell in clamping the cable; after the limit cylinder passes through the two limit clamps, it can prevent the two connected cables from twisting individually, thereby increasing the stability of the cable connection, achieving the purpose that the two cable sections are not easily separated from each other due to external pulling or shaking, and avoiding the problem that the two cable sections are easily separated due to external pulling or shaking due to the lack of a well-balanced stable clamping structure.

DETAILED DESCRIPTION

[0023] See also Figures 1-5, a cable connection insulating clip, comprising a fixed shaft 1, the outer surface of the fixed shaft 1 is fixedly connected with a handle block 2, and a stable clamping mechanism 3 is arranged on the outer side of the fixed shaft 1. The stable clamping mechanism 3 includes two first arc-shaped clamping shells 301 and two second arc-shaped clamping shells 302. The outer surfaces of the two first arc-shaped clamping shells 301 and the outer surfaces of the two second arc-shaped clamping shells 302 are fixedly connected with limit blocks 303. The inner walls of the two first arc-shaped clamping shells 301 and the inner walls of the two second arc-shaped clamping shells 302 are rotatably connected to the outer surface of the fixed shaft 1. The outer surface of the handle block 2 is fixedly connected with a first anti-slip pad 4, and both side surfaces of the first anti-slip pad 4 are fixedly connected with a number of identical first anti-slip convex columns 5. By providing the first anti-slip convex columns 5, the friction on the outer surface of the first anti-slip pad 4 can be increased. Furthermore, the first anti-slip pad 4 and the first anti-slip convex columns 5 can jointly increase the friction on the outer surface of the handle block 2, thus facilitating a person to firmly hold the handle block 2 when using the insulating clip.

[0024] Two limit cylinders 304 are arranged on the outer side of the fixed shaft 1. The inner wall of each first arc-shaped clamping shell 301 is threadedly connected with a hand-twist adjusting bolt 305. The outer surface of each limit cylinder 304 is in contact with the inner wall of the limit block 303. The inner wall of each first arc-shaped clamping shell 301 is fixedly connected with a first insulating anti-slip pad 7, and the inner wall of each second arc-shaped clamping shell 302 is fixedly connected with a second insulating anti-slip pad 8. By providing the first insulating anti-slip pad 7 and the second insulating anti-slip pad 8, the insulation and anti-slip properties of the inner wall of the first arc-shaped clamping shell 301 and the inner wall of the second arc-shaped clamping shell 302 can be increased respectively, so that the two connected cables are clamped more stably.

[0025] An adjusting block 306 is slidably connected inside each first arc-shaped clamping shell 301. The inner wall of each adjusting block 306 is fixedly connected with an auxiliary bearing 307. The inner ring of each auxiliary bearing 307 is fixedly connected with the outer surface of the hand-twist adjusting bolt 305. The inner wall of each limit cylinder 304 is threadedly connected with a hand-twist limit bolt 6. The outer surface of each hand-twist limit bolt 6 is in contact with the outer surface of the limit block 303. By providing the hand-twist limit bolt 6, after the limit cylinder 304 penetrates into the inside of the limit block 303, it can be threadedly connected with the inner wall of the limit cylinder 304, and then block the limit block 303 above the limit cylinder 304, thereby preventing the limit cylinder 304 from disengaging from the inside of the two limit blocks 303, and playing a role in increasing the relative stability between the two first arc-shaped clamping shells 301 and the relative stability between the two second arc-shaped clamping shells 302.

[0026] A fixing rod 308 is fixedly connected to the front surface of each adjusting block 306, a limiting rod 309 is fixedly connected to the front surface of each second arc-shaped clamping shell 302, a limiting slider 11 is fixedly connected to the upper surface and the bottom surface of each adjusting block 306, and the outer surface of each limiting slider 11 is slidably connected to the inside of the first arc-shaped clamping shell 301. By providing the limiting slider 11, it can slide topward inside the first arc-shaped clamping shell 301, which plays a role in increasing the sliding stability of the adjusting block 306 and preventing the adjusting block 306 from sliding out of the inside of the first arc-shaped clamping shell 301.

[0027] A limiting block 310 is provided on the outside of each first arc-shaped clamping shell 301. The inner wall of each limiting block 310 is rotatably connected to the outer surface of the fixing rod 308, the inside of each limiting block 310 is clamped with the outer surface of the limiting rod 309, a second anti-slip pad 9 is fixedly connected to the outer surface of each hand-tightening adjusting bolt 305, and a number of identical second anti-slip convex columns 10 are fixedly connected to the upper surface and the bottom surface of each second anti-slip pad 9. By providing the second anti-slip convex columns 10, the anti-slip property of the outer surface of the second anti-slip pad 9 can be increased. Furthermore, the second anti-slip pad 9 and the second anti-slip convex columns 10 can jointly increase the anti-slip performance of the handle part of the hand-tightening adjusting bolt 305, which plays a role in facilitating the screwing of the hand-tightening adjusting bolt 305.

[0028] The working principle of the present utility model is as follows: When in use, first make appropriate wiring and insulating wrapping connections for two sections of cables, then hold the handle block 2 by hand to take the entire insulating clamp to the connection point, pre-dial the two limiting blocks 310 away from the clamping with the limiting rod 309, and then rotate the two groups of first arc-shaped clamping shells 301 and second arc-shaped clamping shells 302 around the fixed shaft 1 and move away from each other. Place the connection part of the two sections of cables in the middle of the handle block 2, and then rotate the two groups of first arc-shaped clamping shells 301 and second arc-shaped clamping shells 302 around the fixed shaft 1 respectively to wrap the two sections of cables respectively, and make the first insulating anti-slip pad 7 and the second insulating anti-slip pad 8 closely adhere to the outer surface of the cables respectively. According to the thickness of the cables, turn the hand-tightening adjusting bolt 305 with the assistance of the auxiliary bearing 307 to adjust the positions of the adjusting block 306 and the fixing rod 308 relative to the first arc-shaped clamping shell 301 until the limiting block 310 is rotated around the fixing rod 308 and clamped with the limiting rod 309. Then turn the hand-tightening adjusting bolt 305 again to pull the fixing rod 308 in the direction away from the limiting rod 309 until the limiting block 310 clamps the limiting rod 309 tightly. Finally, pass each limiting cylinder 304 through the two limiting blocks 303 respectively and thread it with the hand-tightening limiting bolt 6 to prevent any section of the cable from being twisted alone, thereby increasing the overall stability after the connection of the two sections of cables. The design of the entire cable connection insulating clamp effectively solves the problem that due to the lack of a stable clamping structure with good balance, the two sections of cables are likely to fall off due to external pulling or shaking.

[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
