Description

Technical Field

[0001] This utility model relates to the field of parallel groove wire clamps, and in particular to a special-shaped parallel groove wire clamp. Background Technology

[0002] Parallel groove clamps are accessories used in power systems to connect cables or wires. They connect two or more cables or wires together to ensure that current can pass through and be transmitted normally. They are commonly used in high-voltage transmission lines, power distribution systems, communication lines, and other occasions where power transmission is required.

[0003] When using parallel groove clamps, the first and second clamps contact the cable. A mounting bolt passes through both clamps, and a nut is used to thread the bolt, securing it to the second clamp. The first clamp, being irregularly shaped, clamps the cable securely. However, changes in ambient temperature can cause the cable to expand or contract, leading to over-tightening or loosening of the parallel groove clamp. The clamp cannot automatically adjust to these changes. When the cable expands due to temperature variations, the clamping force may be too strong, causing excessive pressure or damage. Conversely, when the temperature drops and the cable contracts, the clamping force may be insufficient to maintain a stable connection, thus affecting the clamp's performance. Utility Model Content

[0004] The technical problem this utility model aims to solve is that, under varying ambient temperatures, the expansion or contraction of cables can cause the parallel groove clamps to become overly tight or loose. The parallel groove clamps cannot automatically adjust to adapt to changes in cable size. When temperature changes cause the cable to expand, the clamping force may be too strong, leading to excessive pressure or damage to the cable. When the temperature decreases, the cable contracts, and the clamping force may be insufficient to maintain a stable connection, thus affecting the performance of the parallel groove clamps.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a special-shaped parallel groove cable clamp, including a first clamping plate, a mounting bolt inserted on one side of the first clamping plate, a second clamping plate provided on one side of the mounting bolt, a nut threadedly inserted on one side of the mounting bolt, the nut abutting against the second clamping plate on one side, and adaptive devices provided on both sides of the second clamping plate. The adaptive devices adjust the cable clamping force through springs and adjusting plates.

[0006] Preferably, the adaptive device includes a spring, a connecting plate, a round rod, and an adjusting plate. The spring is disposed on the side of the second clamping plate away from the first clamping plate, and both ends of the spring are connected to the second clamping plate and the connecting plate, respectively. The round rod is disposed on the side of the connecting plate close to the second clamping plate, and the round rod is inside the spring and passes through the second clamping plate. The adjusting plate is disposed on the side of the round rod away from the connecting plate, and its size is adapted to the size of the second clamping plate.

[0007] Preferably, the round rod has a reinforcing plate on the side near the adjusting plate, and one side of the reinforcing plate is connected to the adjusting plate.

[0008] Preferably, the adjustment plate is provided with a rubber pad on the side away from the round rod, and the rubber pad increases the friction between the adjustment plate and the cable.

[0009] Preferably, the upper end of the second clamping plate is provided with a protective device, which includes a fixing bolt, a fixing plate and a protective cover. The fixing bolt is inserted into one side of the fixing plate to connect with the second clamping plate. The protective cover is provided on both sides of the fixing plate and the size of the protective cover is adapted to the size of the spring.

[0010] Preferably, the protective cover has an exhaust port on one side at an angle to make it easier for the connecting plate to move inside the protective cover.

[0011] Preferably, several anti-slip blocks are provided on both sides of the fixing plate to increase the friction on both sides of the fixing plate.

[0012] Preferably, the connecting plate is trapezoidal on the side away from the spring to reduce the size of one side of the connecting plate.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] By using an adaptive device, when the second clamp is fixed to the cable, the adjusting plate on one side of the second clamp automatically changes position via a spring when the cable expands or contracts, maintaining a suitable clamping force and then automatically adjusting the torque to ensure a continuous and stable contact force, thereby improving the performance of the parallel groove cable clamp.

[0015] By using protective devices, the spring can be shielded and protected, preventing it from being corroded by rainwater and affecting its service life, thereby extending the service life of the adaptive device. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Figures 1 to 6The illustrated non-standard parallel cable clamp includes a first clamping plate 1. A mounting bolt 2 is inserted into one side of the first clamping plate 1, and a second clamping plate 3 is located on the other side of the mounting bolt 2. A nut 4 is threaded into one side of the mounting bolt 2, and the nut 4 abuts against the second clamping plate 3. Adaptive devices 5 are located on both sides of the second clamping plate 3. The adaptive devices 5 adjust the cable clamping force via a spring 51 and an adjusting plate 54. When using the parallel cable clamp, the first clamping plate 1 and the second clamping plate 3 contact the cable. The mounting bolt 2 passes through the first clamping plate 1 and the second clamping plate 3. The nut 4 is then threaded into the mounting bolt 2, and abuts against the second clamping plate 3 for fixation. The first clamping plate 1 and the second clamping plate 3 then clamp and fix the cable. The adaptive devices 5 adjust the cable clamping force during this process. The non-standard shape of the first clamping plate 1 further enhances the cable clamping and fixation.

[0027] Figures 1 to 6 The adaptive device 5 shown includes a spring 51, a connecting plate 52, a round rod 53, and an adjusting plate 54. The spring 51 is located on the side of the second clamping plate 3 away from the first clamping plate 1, and both ends of the spring 51 are connected to the second clamping plate 3 and the connecting plate 52, respectively. The round rod 53 is located on the side of the connecting plate 52 close to the second clamping plate 3, and the round rod 53 is inside the spring 51 and passes through the second clamping plate 3. The adjusting plate 54 is located on the side of the round rod 53 away from the connecting plate 52, and its size is adapted to the size of the second clamping plate 3.

[0028] Figures 1 to 6 As shown, when the second clamping plate 3 contacts the cable, the adjusting plate 54 also contacts the cable. When the first clamping plate 1 and the second clamping plate 3 clamp the cable, the adjusting plate 54 moves closer to the second clamping plate 3. Then, the round rod 53 fixed on one side of the adjusting plate 54 slides inside the second clamping plate 3. Immediately afterwards, the round rod 53 moves upward with the connecting plate 52 fixed on one side. Here, the spring 51 fixed to the connecting plate 52 and the second clamping plate 3 is stretched and deformed. Then, when the cable expands or contracts due to temperature, the spring 51 is stretched or reset. Then, through the movement of the connecting plate 52 and the round rod 53, the adjusting plate 54 is driven to keep in contact with the cable and adaptively ensures a suitable clamping force. By using the adaptive device 5, when the second clamping plate 3 is clamped and fixed with the cable, and the cable expands or contracts, the adjusting plate 54 on one side of the second clamping plate 3 can automatically change position through the spring 51 to maintain a suitable clamping force and then complete the automatic adjustment torque to ensure a continuous and stable contact force, thereby improving the performance of the parallel groove clamp.

[0029] Figures 1 to 6A reinforcing plate 55 is provided on the side of the round rod 53 near the adjusting plate 54, and one side of the reinforcing plate 55 is connected to the adjusting plate 54. The reinforcing plate 55 is fixed to the round rod 53 and the adjusting plate 54, thereby increasing the connection strength between the round rod 53 and the adjusting plate 54 and preventing deformation at the connection point, which could affect the use of the adjusting plate 54. A rubber pad 56 is provided on the side of the adjusting plate 54 away from the round rod 53. The rubber pad 56 increases the friction between the adjusting plate 54 and the cable. By fixing the adjusting plate 54 away from the round rod 53 with the rubber pad 56, the friction between the adjusting plate 54 and the cable is increased, thereby improving the performance of the adjusting plate 54.

[0030] Figures 1 to 6 The upper end of the second clamping plate 3 shown is provided with a protective device 6. The protective device 6 includes a fixing bolt 61, a fixing plate 62, and a protective cover 63. The fixing bolt 61 is inserted into one side of the fixing plate 62 to connect with the second clamping plate 3. The protective cover 63 is set on both sides of the fixing plate 62, and the size of the protective cover 63 is adapted to the size of the spring 51. Before using the spring 51, move the fixing plate 62 so that the fixing plate 62 contacts the second clamping plate 3. At this time, the protective cover 63 covers and protects the spring 51 and the connecting plate 52. Then, rotate the fixing bolt 61 so that the fixing bolt 61 passes through the fixing plate 62 and is threaded to the second clamping plate 3. Then the position of the protective cover 63 is fixed. By using the protective device 6, the spring 51 can be shielded and protected, avoiding the spring 51 from being corroded by rainwater and affecting the service life of the spring 51, thereby improving the service life of the adaptive device 5.

[0031] Figures 1 to 6 The protective cover 63 shown has an inclined vent 64 on one side to facilitate the movement of the connecting plate 52 inside the protective cover 63. By having the vent 64 inclined on one side of the protective cover 63, air is expelled from inside the protective cover 63 when the connecting plate 52 is brought close to the inner wall of the protective cover 63 by the spring 51. This allows the spring 51 to deform better and adapt, thereby improving its performance. Several anti-slip blocks 65 are provided on both sides of the fixing plate 62 to increase the friction on both sides of the fixing plate 62. By fixing several anti-slip blocks 65 on both sides of the fixing plate 62, the friction on both sides of the fixing plate 62 is increased, making it easier for the operator to hold and move the fixing plate 62. The side of the connecting plate 52 away from the spring 51 is trapezoidal to reduce the size of this side. This trapezoidal shape of the connecting plate 52 away from the spring 51 reduces the size of this side, making it easier for the protective cover 63 to cover the connecting plate 52 and the spring 51 for use.

[0032] Working principle: When using the cable clamp, the first clamp 1 and the second clamp 3 come into contact with the cable. Then, the mounting bolt 2 passes through the first clamp 1 and the second clamp 3. Then, the nut 4 is used to connect with the mounting bolt 2 by thread, and the nut 4 abuts against the second clamp 3 to fix it. Then, the first clamp 1 and the second clamp 3 clamp and fix the cable. At this time, the adaptive device 5 adjusts the clamping force of the cable. The first clamp 1 is irregularly shaped to better clamp and fix the cable. When the second clamping plate 3 contacts the cable, the adjusting plate 54 also contacts the cable. When the first clamping plate 1 and the second clamping plate 3 clamp the cable, the adjusting plate 54 moves closer to the second clamping plate 3. Then, the round rod 53 fixed on one side of the adjusting plate 54 slides inside the second clamping plate 3. Immediately afterwards, the round rod 53 moves upward with the connecting plate 52 fixed on one side. Here, the spring 51 fixed to the connecting plate 52 and the second clamping plate 3 is stretched and deformed. Then, when the cable expands or contracts due to temperature, the spring 51 is stretched or reset. Then, through the movement of the connecting plate 52 and the round rod 53, the adjusting plate 54 is driven to keep in contact with the cable and adaptively ensures a suitable clamping force. By using the adaptive device 5, when the second clamping plate 3 is clamped and fixed with the cable, and the cable expands or contracts, the adjusting plate 54 on one side of the second clamping plate 3 can automatically change position through the spring 51 to maintain a suitable clamping force and complete the automatic adjustment torque to ensure a continuous and stable contact force, thereby improving the performance of the parallel groove clamp.

[0033] Before using spring 51, move the fixing plate 62 so that it contacts the second clamping plate 3. At this time, the protective cover 63 covers and protects spring 51 and connecting plate 52. Then, rotate the fixing bolt 61 so that the fixing bolt 61 passes through the fixing plate 62 and is threadedly fixed to the second clamping plate 3. Then, the position of the protective cover 63 is fixed. By using the protective device 6, the spring 51 can be shielded and protected to prevent the spring 51 from being corroded by rainwater and affecting the service life of the spring 51, thereby improving the service life of the adaptive device 5.

However, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, shall still fall within the protection scope of this utility model's technical solution. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.
