Description

Technical Field

[0001] This utility model relates to an adjustable universal cable clamp, belonging to the field of cable clamp technology. Background Technology

[0002] Cable clamps, as key components used to secure cables in power transmission systems, serve to support, fix, and protect cables. In fields such as power engineering and telecommunications engineering, they not only organize cable layouts systematically, preventing safety hazards caused by tangled cables, but also effectively distribute cable weight, preventing damage from long-term sagging and extending cable lifespan. Furthermore, cable clamps help maintain safe spacing between cables, ensuring stable power transmission, and also facilitate future cable inspection, maintenance, and replacement, improving the reliability and maintainability of the entire power system.

[0003] However, current cable clamps on the market lack versatility. For example, during the design and installation of indoor AC metal-enclosed switchgear, if a change in cable specifications occurs, resulting in a mismatch with the original design, it can cause difficulties in fixing the cable or even make it impossible to fix it at all.

[0004] Therefore, an adjustable universal cable clamp was designed, which can adapt to more cable specifications by adjusting the spacing, thus improving the versatility of the cable clamp. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an adjustable universal cable clamp, which solves the problem that the universality of current cable clamps needs to be improved.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] An adjustable universal cable clamp, comprising:

[0008] A cable bracket, wherein a first elongated slot is provided on the cable bracket;

[0009] The adjustable clamp is composed of an L-shaped left clamp and a right clamp that are fixed to the first elongated hole of the cable bracket. The left clamp and the right clamp are formed by bending a U-shaped bracket at a right angle. The left clamp, the right clamp, and the cable bracket together form a rectangular cable clamping cavity with an adjustable width. The overlapping contact section of the left clamp and the right clamp is an overlapping U-shaped groove segment that is tightly inserted together. One of the U-shaped groove segments has a second elongated hole along the adjustment direction. The U-shaped groove segments of the left clamp and the right clamp are fixed together by screwing through the second elongated hole.

[0010] The positioning and clamping assembly includes a set of positioning and clamping components for clamping the cable, which are respectively installed on the left and right clamping bodies. The positioning and clamping assembly includes an adjusting screw that is screwed into and passes through the left and right clamping bodies, and an arc-shaped pressure plate that is rotatably installed at the inner end of the adjusting screw. The arc-shaped pressure plate symmetrically clamps the cable in the middle.

[0011] Preferably, a silicone rubber protective pad is fixed on the surface of the arc-shaped pressure plate that contacts the cable.

[0012] Preferably, the positioning and clamping assembly further includes a rivet nut and a tightening nut. The rivet nut is fixed to the left and right clamping bodies by a rivet structure, and the tightening nut is located outside the rivet nut and screwed onto the adjusting screw.

[0013] Preferably, the cable bracket also has multiple mounting holes.

[0014] Preferably, the left and right clamps are provided with an adjustment and fixing plate at one end connected to the cable bracket, and the left and right clamps are screwed to the first elongated hole of the cable bracket through the adjustment and fixing plate.

[0015] The beneficial effects of this utility model are:

[0016] (1) The left clamp and the right clamp are screwed and fixed respectively through the first elongated hole on the cable bracket. The distance between the left clamp and the right clamp can be adjusted according to the specifications of the cable.

[0017] (2) After the distance between the left and right clamps is adjusted and fixed according to the specifications of the cable, the cable can be suspended and clamped in the middle by the positioning clamping assembly for fixation.

[0018] (3) Using non-conductive silicone rubber protective pads as an insulating protective layer can not only prevent damage to the surface insulation performance of the cable during clamping, but also add an extra layer of insulation between the cable clamp and the cable, making it safer.

[0028] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0029] like Figure 1 As shown, this adjustable universal cable clamp includes: a cable bracket 1 for fixing to the mounting surface, an adjustable clamp body 2 fixed to the cable bracket 1 and capable of adjusting the spacing, and a pair of positioning and clamping components 3 mounted on the adjustable clamp body 2.

[0030] The cable bracket 1 is a straight, non-magnetic stainless steel bracket with a U-shaped cross-section. The upper and lower sides are bent to increase strength. A first elongated hole 101 is provided on the straight cable bracket 1. The first elongated holes 101 are symmetrically arranged on the left and right sides of the straight cable bracket 1. The cable bracket 1 also has multiple mounting holes 102, through which it is screwed and fixed to the mounting surface. For example, the cable bracket 1 is screwed and fixed inside a switchgear device through the mounting holes 102.

[0031] like Figures 2-4As shown, the adjustable clamp 2 consists of an L-shaped left clamp 201 and a right clamp 202, which are fixed to the first elongated hole 101 of the cable bracket 1. The left clamp 201 and the right clamp 202 are formed by bending the U-shaped bracket at right angles to form the L-shape. The left clamp 201 and the right clamp 202 are both made of non-magnetic stainless steel. The U-shaped cross section is formed by bending the upper and lower sides to provide reinforcement. The left clamp 201, the right clamp 202 and the cable bracket 1 form a rectangular cable clamping cavity 203 with an adjustable width. The left clamp 201 and the right clamp 202 can move towards the center along the first elongated hole 101 of the cable bracket 1 to accommodate thinner cables 4. The left clamp 201 and the right clamp 202 can move towards both ends along the first elongated hole 101 of the cable bracket 1 to accommodate thicker cables 4. The L-shaped left clamp 201 and right clamp 202 move towards each other, and their overlapping contact section is a tightly interlocking U-shaped groove segment 204. The two U-shaped groove segments 204 are of different sizes and fit together tightly. One of the U-shaped groove segments 204 has a second elongated hole 205 along the adjustment direction. The U-shaped groove segments 204 of the left clamp 201 and right clamp 202 are screwed together and fixed by the second elongated hole 205. After the U-shaped groove segments 204 of the left clamp 201 and right clamp 202 are fixed, they fit tightly together by relying on the vertical edges. The U-shaped groove segments 204 can limit each other and prevent deformation and displacement.

[0032] A set of positioning clamping components 3 for clamping the cable 4 is respectively installed on the left clamp 201 and the right clamp 202. The positioning clamping components 3 include adjusting screws 301 that are screwed into and pass through the left clamp 201 and the right clamp 202, and arc-shaped pressure plates 302 that are rotatably installed on the inner end of the adjusting screws 301. The arc-shaped pressure plates 302 symmetrically clamp the cable 4 in the middle. A sleeve 303 is provided in the middle of the outer arc of the arc-shaped pressure plate 302. The adjusting screws 301 are pressed against the sleeve 303 to achieve a rotatable connection. When clamping the cable 4, the adjusting screws 301 press against the center from the sleeve of the left clamp 201 and the right clamp 202 so that the left clamp 201 and the right clamp 202 clamp the cable 4 from the left and right sides.

[0033] An adjusting and fixing plate 206 is provided at one end of the left clamp 201 and right clamp 202 that connects to the cable bracket 1. The left clamp 201 and right clamp 202 are screwed and fixed to the first elongated hole 101 of the cable bracket 1 via the adjusting and fixing plate 206. The adjusting and fixing plate 206 and the L-shaped left clamp 201 and right clamp 202 are of an integral structure. The adjusting and fixing plate 206 is parallel to the plane of the first elongated hole 101 of the cable bracket 1 and is fixed by screws. The adjusting and fixing plate 206 makes the rectangular cable clamping cavity 203 more stable.

[0034] The left clamp 201 and the right clamp 202 are screwed and fixed through the first elongated hole 101 on the cable bracket 1. The spacing between the left clamp 201 and the right clamp 202 can be adjusted according to the specifications of the cable 4.

[0035] like Figure 3 As shown, in some embodiments, a silicone rubber protective pad 304 is fixed on the surface of the arc-shaped pressure plate 302 that contacts the cable 4.

[0036] After the spacing between the left clamp 201 and the right clamp 202 is adjusted and fixed according to the specifications of the cable 4, the cable 4 can be suspended and clamped in the middle by the positioning clamping assembly 3 for fixation. The silicone rubber protective gasket 304 has the characteristics of being soft and non-conductive. The soft and non-conductive silicone rubber protective gasket 304 is used as an insulating protective layer between the cable 4 clamp and the cable 4. It can not only prevent the edges of the left clamp 201 and the right clamp 202 of the cable 4 clamp from damaging the surface insulation performance of the cable 4 during clamping, but also add an extra layer of insulation between the cable 4 clamp and the cable 4, making it safer.

[0037] like Figure 3 As shown, in some embodiments, the positioning and clamping assembly 3 further includes a rivet nut 305 and a tightening nut 306. The rivet nut 305 is fixed to the left clamping body 201 and the right clamping body 202 by a rivet structure, and the tightening nut 306 is located outside the rivet nut 305 and screwed onto the adjusting screw 301. By fixing the rivet nut on the left clamping body 201 and the right clamping body 202, a threaded hole is formed for the adjusting screw 301 to pass through. After the adjusting screw 301 is screwed into the rivet nut, it passes through and then presses against the arc-shaped pressure plate 302 to position and lock the cable 4.

[0038] How to use:

[0039] First, rotate the adjusting screws 301 on the left clamp 201 and the right clamp 202 outwards so that the two arc-shaped pressure plates 302 are as close as possible to the inner walls of the left clamp 201 and the right clamp 202.

[0040] Then, the left clamp 201 and right clamp 202 are symmetrically fixed along the first elongated hole 101 of the cable bracket 1. The overlapping U-shaped grooves 204 of the left clamp 201 and right clamp 202 are tightly inserted together, so that the cable 4 is located in the rectangular cable clamping cavity 203 formed by the left clamp 201, right clamp 202 and cable bracket 1. Then, it is further adjusted to the center until the distance between the cable 4 and the arc-shaped pressure plates 302 on both sides is within the range that the adjusting screw 301 can lock. At this time, the second elongated hole 205 of the U-shaped grooves 204 of the left clamp 201 and right clamp 202 is screwed and tightened.

[0041] Finally, alternately tighten the adjusting screws 301 on the left and right sides until the silicone rubber protective gasket 304 is in close contact with the cable 4, and apply appropriate tightening force to tighten the outer end face of the nut 306 and the rivet nut 305 to prevent loosening.

[0042] This adjustable universal cable clamp can be adjusted according to the diameter of the cable 4 to accommodate cables of different specifications. The main body is made of non-magnetic stainless steel, which is wear-resistant and corrosion-resistant. A silicone rubber protective pad 304 is added to the contact surface with the cable 4 to prevent damage to the cable 4 surface and affect its insulation performance, and to increase friction to prevent the cable 4 from slipping. The overall structure is stable and easy to install and disassemble. All screw connections in this structure can be fixed and positioned using standard screws, and the installation process will not damage the cable 4.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
