Description

Technical Field

[0001] This utility model relates to the field of power fittings equipment technology, and in particular to an anti-arc composite power fitting. Background Technology

[0002] Composite power fittings are metal accessories used in power systems to connect and fix transmission lines and equipment. They are usually made of non-ferrous metals such as aluminum, aluminum alloys, and copper. The parts that come into direct contact with the conductors are made of metal materials with good electrical conductivity. Composite power fittings are mainly used to transmit mechanical and electrical loads and provide protection to ensure the stable operation of power lines.

[0003] Most common parallel groove wire clamps and irregular parallel groove wire clamps on the market currently use a method where the upper and lower clamps are fixed to the upper and lower sides of two wires respectively, and bolts are used to pass through the two clamps and tighten them with nuts to achieve the side-by-side fixation of the two wires. However, this method is usually suitable for situations where the two wires are of similar size and thickness. When encountering wires of different sizes and thicknesses, the method of fixing by squeezing from the top and bottom can often only effectively fix the thicker wire, and cannot simultaneously and securely fix both wires.

[0004] Therefore, the limitations of traditional wire clamps become apparent in practical applications. Especially in power systems, where wires come in various specifications and thicknesses, traditional parallel groove clamps and irregularly shaped parallel groove clamps may encounter challenges in fixing them, resulting in poor fixing effects and even safety hazards.

[0005] To address the above issues, we have developed an anti-arc composite power fitting. Utility Model Content

[0006] This utility model discloses an anti-arc composite power fitting, which aims to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An anti-arc composite power fitting includes two power clamps symmetrically arranged. Each of the two power clamps has a connecting block fixedly connected to its opposite side. Each of the two power clamps has an anti-electric insulation layer fixedly connected inside. Each of the two power clamps has a first groove, which penetrates both the power clamp and the anti-electric insulation layer. Each of the two power clamps has an arc-shaped block fixedly connected symmetrically. Each of the four arc-shaped blocks has an arc-shaped groove.

[0009] In a preferred embodiment, a rotating ring is provided on each of the two arc-shaped blocks, and a limiting block is symmetrically fixedly connected inside each of the two rotating rings. The limiting block is slidably connected to the corresponding arc-shaped groove.

[0010] In a preferred embodiment, both rotating rings are provided with force-applying holes.

[0011] In a preferred embodiment, a second groove is formed in both connecting blocks, and a third groove is formed in both connecting blocks, with the rotating ring located in the second groove.

[0012] In a preferred embodiment, a connecting crossbar is placed between the two third grooves, and rectangular blocks are symmetrically fixedly connected to the sides of the connecting crossbar. The rectangular blocks are slidably connected to the third grooves, and holes are equidistantly opened on the connecting blocks. Threaded holes are opened on the rectangular blocks, and the holes and threaded holes are used in conjunction.

[0013] The anti-arc composite power fitting provided by this utility model has the following advantages:

[0014] Firstly, due to the unique shape of the arc-shaped groove, workers can rotate the rotating rings individually, allowing the limiting block to gradually transition from the high-width area to the low-width area during sliding, thus achieving gradual tightening of the wire. The shape of the arc-shaped groove adapts to the needs of wires of different sizes and thicknesses. Since wire clamp installation involves working at heights, it is difficult for workers to carry specialized wire clamps for different wire thicknesses at all times, thus effectively improving work efficiency.

[0015] Secondly, since the length of the wire fixed inside the power clamp directly affects its conductivity, workers can adjust the wire's length by pushing the rectangular blocks connected to both sides of the connecting crossbar after fixing the wire. Once a suitable position is determined, bolts or other workpieces are used to pass through the holes and rotate them into the threaded holes via threaded connections to complete the fixing.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] This utility model discloses an anti-arc composite power fitting.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an anti-arc composite power fitting includes a power clamp 1, two power clamps 1 are symmetrically arranged, a connecting block 2 is fixedly connected to the opposite side of each of the two power clamps 1, an anti-electric insulation layer 3 is fixedly connected inside each of the two power clamps 1, a first groove 4 is opened inside each of the two power clamps 1, the two first grooves 4 penetrate the power clamp 1 and the anti-electric insulation layer 3, and an arc-shaped block 5 is symmetrically fixedly connected to each of the two power clamps 1, and an arc groove 501 is opened on each of the four arc blocks 5.

[0026] In this embodiment, it should be noted that the two ends of the arc groove 501 are not at the same height, and the arc width of the arc groove 501 is set to gradually decrease. The width of the lower part of the arc groove 501 is greater than the width of the higher part. Since the anti-electric insulation layer 3 belongs to the prior art, it is not subject to special constraints, and it is sufficient to have anti-arc capability.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a rotating ring 6 is provided on each of the two corresponding arc-shaped blocks 5, and a limiting block 7 is symmetrically fixedly connected inside each of the two rotating rings 6. The corresponding limiting block 7 is slidably connected to the corresponding arc-shaped groove 501.

[0028] In this embodiment: In actual operation, the operator first places the wires to be connected side by side into the power clamp 1, and then rotates the rotating ring 6 to drive the connected limiting block 7 to make frictional contact movement within the arc-shaped groove 501. Due to the special shape of the arc-shaped groove 501, the limiting block 7 will gradually move from the high width area to the low width area during the sliding process, thereby gradually tightening the wires until they are finally fixed.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, both rotating rings 6 are provided with force-applying holes 8.

[0030] In this embodiment, the power line clamp 1 is locked by inserting a lever into the lever hole 8 and rotating the lever.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a second groove 9 is provided in both connecting blocks 2, a third groove 10 is provided in both connecting blocks 2, and the rotating ring 6 is located in the second groove 9.

[0032] In this embodiment: Since the installation of electrical fittings is a high-altitude operation, the second groove 9 is set up to place the rotating ring 6, so as to save the time of workers searching for parts.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, a connecting crossbar 11 is placed between the two third grooves 10. A rectangular block 12 is symmetrically fixed to the side of the connecting crossbar 11. The rectangular block 12 is slidably connected to the third groove 10. Holes 14 are equidistantly opened on the connecting block 2. Threaded holes 13 are opened on the rectangular block 12. The holes 14 and threaded holes 13 are used in conjunction.

[0034] In this embodiment: Since the length of the wire fixed inside the power clamp 1 directly affects the conductivity of the wire, after fixing the wire, the worker can adjust the fixed length of the wire by pushing the rectangular blocks 12 connected to both sides of the connecting crossbar 11. After determining the appropriate position, a bolt or other workpiece is used to pass through the hole 14 and rotate it to the threaded hole 13 through a threaded connection to finally complete the fixing.

[0035] Working principle: In actual operation, the operator first places the wires to be connected side-by-side into the power line clamp 1. Then, by rotating the rotating ring 6, the connected limiting block 7 is driven to make frictional contact movement within the arc-shaped groove 501. Due to the special shape of the arc-shaped groove 501, the limiting block 7 gradually transitions from a high-width area to a low-width area during the sliding process, thereby gradually tightening the wires. Next, by inserting the force-applying rod into the force-applying hole 8 and rotating the force-applying rod, the power line clamp 1 reaches the locked state.

[0036] After the wire is fixed, the fixed length of the wire can be adjusted by pushing the rectangular blocks 12 connected to both sides of the connecting crossbar 11. After determining the appropriate position, use bolts or other workpieces to pass through the holes 14 and rotate them to the threaded holes 13 through the threaded connection to finally complete the fixing.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
