Technical Field
[0001] This utility model relates to the field of wire clamp technology, and in particular to a grooved wire clamp. Background Technology
[0002] Parallel groove clamps are hardware used to connect and fix conductors in power lines. Parallel groove clamps place two or more conductors side by side in their grooves, and use the pressure of the clamp plates to maintain good electrical contact between the conductors, thereby enabling smooth current transmission. The clamp's fastening structure can ensure that the connection between the conductors remains stable under various environmental conditions, preventing the conductors from loosening or falling off due to external forces.
[0003] A search revealed Chinese patent publication number CN220021629U, which discloses a parallel grooved wire clamp, relating to the field of wire clamp technology. The clamp includes a lower clamp plate with a through hole at its bottom. A fixing tooth is slidably connected to the inner wall of the through hole. An upper clamp plate is fixedly mounted on the top of the fixing tooth. A fixing tube is fixedly mounted on the bottom of the lower clamp plate. A fixing hole is formed on the outer wall of the fixing tube. A circular groove is formed on the outer wall of the fixing tooth, located near the fixing hole.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a parallel groove wire clamp, including a top seat 1, a base 3 at the bottom of the top seat 1, and a fixing plate 4 fixedly connected to the top of the top seat 1. Two bolts 5 pass through the top of the fixing plate 4, and the bottoms of both bolts 5 pass through the top seat 1 and are threadedly connected to the top of the base 3. Nuts 6 are threadedly connected to the bottoms of both bolts 5 to prevent them from coming loose due to vibration. When installing the wire, the wire is placed in the semi-circular hole inside the base 3, and then the top seat 1 and the base 3 are connected together by the bolts 5. Two fixing plates 6 are fixedly connected inside the base 3. The fixed sleeve 7 is used to pass the wire through the fixed sleeve 7. Both fixed sleeves 7 are fixedly connected with rubber rings 8 to prevent damage to the internal structure of the wire when squeezed. Two bolts 9 pass through the top left and right sides of the top of the top seat 1. The bottom of the multiple bolts 9 are threaded to the top of the outer wall of the two rubber rings 8. After the wire is placed inside the fixed sleeve 7, the top seat 1 is covered and connected by bolt 5. Then the bolts 9 pass through the top seat 1 and are threaded to the top of the outer wall of the fixed sleeve 7 to prevent the fixed sleeve 7 from moving and to facilitate the replacement of the rubber rings 8. The top front and rear sides of the top of the top seat 1 are provided with protective mechanisms 2.
[0040] Specifically, the top seat 1 has a base 3 at its bottom, forming the main body of the wire clamp. Two bolts 5 pass through the fixing plate 4 fixedly connected to the top of the top seat 1. These two bolts 5 penetrate the top seat 1 and are threadedly connected to the top of the base 3. Nuts 6 are threadedly connected to the bottom of the base 3. The presence of nuts 6 effectively prevents the bolts 5 from falling off due to vibration, ensuring the stability of the overall structure of the wire clamp. When installing the wire, the wire is first placed in the semi-circular hole inside the base 3. The semi-circular hole design allows for a close fit to the shape of the wire, providing initial positioning and fixation. Then, the top seat 1 and the base 3 are connected by bolts 5, so that the wire is stably clamped between them. Two fixing sleeves 7 are also fixedly connected inside the base 3. The wire needs to be fixed from the fixing... The wire passes through the sleeve 7. Inside each of the two fixed sleeves 7, a rubber ring 8 is fixedly connected. The rubber ring 8 is soft and elastic, which can play a buffering role during clamping and effectively prevent compression from damaging the internal structure of the wire. To further ensure the stability of the fixed sleeve 7 and the replaceability of the rubber ring 8, two bolts 9 pass through the top left and right sides of the top of the top seat 1. After the wire is placed in the fixed sleeve 7, the top seat 1 is covered and connected by bolt 5, and then bolt 9 passes through the top seat 1 to make it threadedly connected to the top of the outer wall of the fixed sleeve 7. The fixed sleeve 7 is fixed and not easy to move. At the same time, when the rubber ring 8 is worn or aged, it can be easily and quickly replaced, which greatly improves the practicality and maintenance convenience of the parallel groove clamp.
[0041] Reference Figure 3 and Figure 5 The protective mechanism 2 includes multiple hinges 201, which are fixedly connected to the front and rear sides of the top of the top seat 1. Protective plates 202 are fixedly connected between the two adjacent front hinges 201 and the two adjacent rear hinges 201 to protect the internal structure. The protective plates 202 are opened and closed by the hinges 201. The two bottom protective plates 202 are fixedly connected to the opposite sides of each other by a buckle retainer 203. The two top protective plates 202 are fixedly connected to the opposite sides of each other by a pipe clamp 204. When the protective plate 202 is closed, the buckle retainer 203 hooks the pipe clamp 204 to prevent the protective plate 202 from opening accidentally. The two bottom protective plates 202 are fixedly connected to the inside by two sealing rings 205. When the wire is placed in, the sealing rings 205 fit the wire to prevent rainwater from entering.
[0042] Specifically, multiple hinges 201 are fixedly connected to the front and rear sides of the top of the top seat 1. Protective plates 202 are fixedly connected between two adjacent hinges 201 on the front and rear sides of the hinges 201, which serve to protect the internal structure of the wire clamp and prevent damage from external factors. The protective plates 202 are opened and closed through the hinges 201, making operation convenient. Each of the two bottom protective plates 202 has a snap fastener 203 installed on the opposite side, and a pipe clamp 204 is fixedly connected to the corresponding position on the top. When the protective plate 202 is closed, the snap fastener 203 hooks the pipe clamp 204 to form a locked state, effectively preventing the protective plate 202 from being opened accidentally and ensuring that the internal structure is always under safe protection. Each of the two bottom protective plates 202 has two sealing rings 205 inside. After the wire is placed in, the sealing rings 205 can fit tightly against the surface of the wire, effectively blocking rainwater from entering and avoiding short circuits and corrosion caused by rainwater intrusion. This comprehensively improves the reliability of the parallel groove wire clamp in complex environments.
[0043] Reference Figure 1 and Figure 2 Both bolts 5 are fixedly connected to washers 10 on the lower part of their outer walls. Both washers 10 are symmetrically designed to prevent bolts 5 from being tightened. Multiple anti-slip tubes 11 are fixedly connected to the left and right sides of the base 3. The multiple anti-slip tubes 11 are rounded to increase the friction with the hand when picking them up. Both bolts 5 have internal hexagonal slots 12 on their tops. The tops of both internal hexagonal slots 12 are chamfered to facilitate opening bolts 5.
[0044] Specifically, the lower part of the outer wall of the two bolts 5 is fixedly connected with symmetrically designed washers 10, which can effectively prevent the bolts 5 from being tightened and ensure the convenience of subsequent disassembly and maintenance. The left and right sides of the base 3 are fixedly connected with multiple anti-slip tubes 11 with a smooth design, which significantly increases the friction with the hand when gripping, making it convenient for construction personnel to pick up and install. The internal hexagonal grooves 12 opened on the top of the two bolts 5 are chamfered, making the operation of opening the bolts 5 easier and smoother. All these features comprehensively improve the convenience and practicality of the parallel groove clamp in actual use.
[0045] Reference Figure 1 and Figure 5 A connecting plate 13 is fixedly connected to the front side of the front top protective plate 202, and a warning sign 14 is fixedly connected to the front side of the connecting plate 13 to remind people to pay attention to safety. The outer walls of the two bolts 15 are equidistant through the top of the fixed plate 4 to ensure uniform pressure. The multiple bolts 29 are all arranged at equal intervals. The outer walls of the multiple protective plates 202 are all chamfered. The diameter of the multiple sealing rings 205 is equal to the diameter of the circular holes between adjacent protective plates 202.
[0046] Specifically, the connecting plate 13 fixedly connected to the front of the top protective plate 202 extends into a warning sign 14, which conspicuously reminds construction and maintenance personnel to pay attention to safety and effectively reduces the risk of accidents. Two bolts 1 5 pass through the fixing plate 4 at equal intervals to ensure that the pressure between the top seat 1 and the base 3 is evenly distributed, improving the clamping stability. Multiple bolts 2 9 are also arranged at equal intervals to ensure the stable fixation of the fixing sleeve 7. The chamfered design of the outer wall of the protective plate 202 avoids sharp edges from causing bumps and injuries. The diameter of the sealing ring 205 is precisely matched with the round hole of the protective plate 202 to ensure waterproof sealing effect and provide reliable protection for the safe operation of the line.
[0047] Working principle: The fixing sleeve 7 is placed in the semi-circular hole inside the base 3. The semi-circular hole fits the shape of the fixing sleeve 7 to complete the initial positioning and fixation. The wire needs to pass through the fixing sleeve 7 inside the base 3. The rubber ring 8 inside the sleeve provides cushioning when the wire is clamped due to its softness and elasticity, avoiding squeezing and damaging the internal structure of the wire. To ensure the stability of the fixing sleeve 7 and the easy replacement of the rubber ring 8, bolts 9 are set on the left and right sides of the top of the top seat 1. After the top seat 1 is connected to the base 3, it passes through the threaded connection between the top seat 1 and the top of the outer wall of the fixing sleeve 7. This not only prevents the fixing sleeve 7 from moving, but also facilitates quick replacement when the rubber ring 8 is worn and aged. Then, bolt 5 passes through the fixing plate 4 at the top of the top seat 1 and is threadedly connected to the top of the base 3. Tighten the nut 6 to achieve a stable connection between the top seat 1 and the base 3, so that the wire is clamped between the two, ensuring the stability of the mechanical connection and ensuring the stable and reliable operation of the parallel groove clamp.
[0048] Furthermore, the protective plate 202 effectively protects the internal structure of the clamp from damage caused by external factors such as impacts and scratches. The protective plate 202 is opened and closed via a hinge 201, facilitating operation during installation, inspection, or maintenance of the clamp's internal structure. A snap-fit retainer 203 is installed on the side of the two bottom protective plates 202 that is far apart from each other, while a pipe clamp 204 is fixedly connected to the corresponding position on the top. When the protective plate 202 is closed, the snap-fit retainer 203 precisely hooks onto the pipe clamp 204, thus locking it in place and effectively preventing accidental opening of the protective plate 202. This ensures that the internal structure of the clamp is always under safe protection. Each of the two bottom snap-fit retainers 203 has two sealing rings 205 inside. When the wire is inserted, the sealing rings 205 tightly adhere to the surface of the wire, effectively preventing rainwater from entering the clamp. This avoids serious problems such as short circuits and corrosion caused by rainwater intrusion, improving the reliability of the parallel groove clamp in various complex environments.
