Description

Technical Field

[0001] This invention relates to the field of power fittings technology, specifically to high-voltage wire clamps with positioning and locking functions. Background Technology

[0002] Power fittings are a general term for metal accessories used in power systems to connect, fix, support, and protect conductors, insulators, towers, and other electrical equipment. They are widely used in power transmission, substation, and distribution. They perform multiple functions in the power grid, including mechanical support, electrical connection, and protective insulation, ensuring the safe and efficient transmission of electrical energy. High-voltage wire clamps are specialized metal components used in power systems to fix conductors and prevent slippage. They are typically made of high-strength aluminum alloy or steel and form a stable connection with the conductor through mechanical crimping or bolt fastening. These fittings are widely used in overhead transmission lines, substations, and distribution networks, undertaking critical functions such as conducting current, distributing mechanical stress, and resisting wind vibration and icing loads. Ensuring continuous conductivity and structural reliability during long-term operation is a crucial component for ensuring the safe and stable operation of the power grid.

[0003] The existing equipment has the following disadvantages: traditional high-voltage wire clamps do not have a quick positioning and locking function. When using them, the end of the cable must be inserted into the clamp, and then the insertion relationship must be manually maintained before tightening the bolts to fix the connection. Manually maintaining the connection requires a certain amount of force, and one hand cannot perform other operations, which leads to inconvenience in operation.

[0004] Therefore, this application proposes a high-voltage clamp power fitting with positioning and locking function to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a high-voltage wire clamping fitting with a positioning and locking function to solve the problem that manually maintaining the plug-in relationship during the wire clamping process leads to inconvenience in operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-voltage wire clamp with positioning and locking function, comprising: Reference component; A positioning and locking mechanism is disposed on the outer wall of the reference component, and the positioning and locking mechanism is used to quickly position and lock the cable; An anti-loosening clamping mechanism is provided on a reference component and a positioning locking mechanism, and is used to clamp the cable to prevent it from loosening. An auxiliary operating mechanism is mounted on a reference component and is used to facilitate wire clamping operations by the user. The positioning and locking mechanism includes a connecting box, which is fixedly installed on the outer wall of the reference component. The top and bottom of the inner wall of the connecting box are provided with grooves, and the top and bottom of the connecting box are provided with through holes. A rotating shaft located in the inner cavity of the groove is rotatably connected to the inner wall of the connecting box. A rotating plate is fixedly sleeved on the outer wall of the rotating shaft. A protrusion is fixedly connected to the end of the rotating plate. A locking elastic element is fixedly installed on the outer wall of the rotating plate. The end of the locking elastic element away from the rotating plate is fixedly installed on the inner wall of the groove.

[0007] The connecting box has a support rod fixedly installed at one end, and a limit plate is fixedly installed at the end of the support rod away from the connecting box.

[0008] The anti-loosening clamping mechanism includes a first support arm and a second support arm. The first support arm is fixedly installed on the outer wall of the connecting box, and the second support arm is fixedly installed on the reference part and the outer wall of the connecting box. A threaded rod is threadedly connected to the inner wall of the first support arm, and a receiving plate is rotatably connected to the end of the threaded rod.

[0009] Among them, arc-shaped clamping parts are fixedly installed on the inner walls of the receiving plate and the second support arm, and anti-slip ridges are fixedly connected to the inner surface of the arc-shaped clamping parts.

[0010] The threaded rod is fixedly connected to a hexagonal cap at the end away from the receiving plate, and a round hole is provided on the outer wall of the hexagonal cap.

[0011] The outer wall of the receiving plate is fixedly installed with a stepping strip plate, which is slidably connected to the inner wall of the first support arm. A square hole is opened on the outer wall of the stepping strip plate.

[0012] The first support arm has a frame fixedly installed on its outer wall. The frame has a second square hole on its side. A support frame is fixedly installed on the side of the frame. A reset elastic element is fixedly installed on the inner surface of the support frame. A collection rod is fixedly installed at the end of the reset elastic element away from the support frame. A pin is fixedly installed on the side of the collection rod. The pin is movably inserted into the inner cavity of the second square hole. A cross handle is fixedly installed on the outer wall of the collection rod. The cross handle is slidably connected to the inner wall of the support frame.

[0013] The reference component has a hanging groove, and a reinforcing foot is fixedly installed on the outer wall of the reference component. The reinforcing foot is fixedly installed on the outer wall of the connecting box.

[0014] The auxiliary operating mechanism includes a support block, a strip-shaped through groove on the reference component, the support block being fixedly installed on the inner wall of the strip-shaped through groove, a vent hole at the bottom of the support block, a contractile elastic element being fixedly installed at the top of the support block, a sliding block being fixedly installed at the top of the contractile elastic element, the sliding block being slidably connected to the inner wall of the strip-shaped through groove, a limit rod being fixedly connected to the top of the sliding block, and a handle being fixedly sleeved on the outer wall of the limit rod.

[0015] The auxiliary operating mechanism further includes an internally threaded cylinder, which is fixedly installed on the top of the reference component. An externally threaded block is threadedly connected to the inner wall of the internally threaded cylinder. An alloy grip is fixedly installed on the outer wall of the externally threaded block. Two limiting wings are fixedly installed on the outer wall of the alloy grip. A rubber anti-slip sleeve located between the two limiting wings is fixedly sleeved on the outer wall of the alloy grip.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the overall design of the positioning and locking mechanism to insert the cable into the inner cavity of the connector box. During the movement of the cable end, it pushes the rotating plate, causing the rotating plate to compress the locking elastic element and rotate into the inner cavity of the groove. After release, the cable will move away from the connector box under its own gravity. At this time, the elastic force of the locking elastic element can push the rotating plate, causing the end of the rotating plate to abut against the outer wall of the cable, and the protrusion to insert into the inside of the cable, thus realizing the positioning and locking function of the cable. The positioning and locking of the cable end is completed by a single insertion, eliminating the need to manually maintain the insertion relationship between the hardware and the cable, freeing the user's hands and facilitating subsequent connection work. When the threaded rod is rotated, the arc-shaped clamping part on the receiving plate moves toward the arc-shaped clamping part on the second support arm. The stepping strip plate slides on the inner wall of the frame. The pin block is provided with an inclined surface. The stepping strip plate pushes the inclined surface, causing the pin block to move toward the support frame. At the same time, it compresses the reset elastic element to facilitate the feeding of the stepping strip plate. When the second square hole corresponds to the first square hole, the elastic force of the reset elastic element can drive the pin block to be inserted into the first square hole, locking the reset action of the stepping strip plate to prevent the receiving plate from moving away from the cable and causing loosening, thus increasing safety. With the design of the hanging slot, when conditions permit, users can suspend the reference part from the hanging slot and then perform the clamping operation, which is more convenient to use. When suspending the reference part from the hanging slot, press down the handle in advance to make the limit rod move down, which drives the sliding block to slide in the strip groove. At the same time, the elastic element is compressed and contracted, making the hanging slot open. After suspension, release the handle. The elastic force of the contracted elastic element drives the handle to return to its original position, closing the opening of the hanging slot and preventing the problem of falling off.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-10 This invention provides a technical solution: a high-voltage wire clamp with positioning and locking function, comprising: Reference component 1; Positioning and locking mechanism 2 is installed on the outer wall of reference component 1. Positioning and locking mechanism 2 is used to quickly position and lock the cable. Anti-loosening clamping mechanism 3 is installed on the reference part 1 and the positioning locking mechanism 2. The anti-loosening clamping mechanism 3 is used to clamp the cable to prevent it from loosening. Auxiliary operating mechanism 4 is set on the reference part 1. Auxiliary operating mechanism 4 is used to facilitate the user to perform wire clamping operation. The positioning and locking mechanism 2 includes a connecting box 21, which is fixedly installed on the outer wall of the reference member 1. The top and bottom of the inner wall of the connecting box 21 are provided with grooves 22 and through holes 23. A rotating shaft 24 located in the inner cavity of the groove 22 is rotatably connected to the inner wall of the connecting box 21. A rotating plate 25 is fixedly sleeved on the outer wall of the rotating shaft 24. A protrusion 27 is fixedly connected to the end of the rotating plate 25. A locking elastic member 26 is fixedly installed on the outer wall of the rotating plate 25. The end of the locking elastic member 26 away from the rotating plate 25 is fixedly installed on the inner wall of the groove 22.

[0021] It should be noted that during use, when the cable is inserted into the inner cavity of the connector box 21, the end of the cable will push the rotating plate 25 during its movement, causing the rotating plate 25 to compress the locking elastic element 26 and then rotate into the inner cavity of the groove 22. After being released, the cable will move away from the connector box 21 under its own gravity. At this time, the elastic force of the locking elastic element 26 can push the rotating plate 25, causing the end of the rotating plate 25 to abut against the outer wall of the cable, and the protrusion 27 to be inserted into the inside of the cable, thereby realizing the function of positioning and locking the cable. Then, the anti-loosening clamping mechanism 3 can be used to clamp the cable a second time.

[0022] In one embodiment, a support rod 28 is fixedly installed at the end of the connecting box 21, and a limiting circular plate 29 is fixedly installed at the end of the support rod 28 away from the connecting box 21.

[0023] This design is for reference. Figure 3When the cable is plugged into the inner cavity of the connector box 21, the design of the limiting plate 29 can limit the end of the cable, avoiding the problem of excessive plugging and cable waste.

[0024] In one embodiment, the anti-loosening clamping mechanism 3 includes a first support arm 31 and a second support arm 32. The first support arm 31 is fixedly installed on the outer wall of the connecting box 21, and the second support arm 32 is fixedly installed on the reference part 1 and the outer wall of the connecting box 21. A threaded rod 33 is threadedly connected to the inner wall of the first support arm 31, and a receiving plate 34 is rotatably connected to the end of the threaded rod 33.

[0025] This design is for reference. Figure 4 , Figure 5 After the cable is inserted into the inner cavity of the connector box 21, the cable can be clamped a second time by rotating the threaded rod 33. The mutual assistance of the double clamping effect improves the stability of the cable connection and increases safety.

[0026] In one embodiment, arc-shaped clamping members 35 are fixedly installed on the inner walls of the receiving plate 34 and the second support arm 32, and anti-slip ridges 36 are fixedly connected to the inner surface of the arc-shaped clamping members 35.

[0027] This design is for reference. Figure 5 Rotating the threaded rod 33 can drive the arc-shaped clamping part 35 on the receiving plate 34 to move toward the arc-shaped clamping part 35 on the second support arm 32, thereby realizing the function of secondary clamping of the cable. The anti-slip ridge 36 design can improve the stability of the clamping.

[0028] In one embodiment, a hexagonal cap 331 is fixedly connected to the end of the threaded rod 33 away from the receiving plate 34, and a round hole 332 is provided on the outer wall of the hexagonal cap 331.

[0029] This design is for reference. Figure 5 When the threaded rod 33 needs to be rotated, an internal hex wrench can be attached to the outer wall of the hexagonal cap 331 to rotate the threaded rod 33, or a thin rod can be inserted into the inside of the round hole 332 to rotate the threaded rod 33, which is convenient for users to operate.

[0030] In one embodiment, a stepping strip plate 37 is fixedly installed on the outer wall of the receiving plate 34. The stepping strip plate 37 is slidably connected to the inner wall of the first support arm 31. A square hole 371 is formed on the outer wall of the stepping strip plate 37.

[0031] This design is for reference. Figure 6 During the process of adjusting the position of the receiving plate 34 by rotating the threaded rod 33, the stepping strip plate 37 will slide on the inner wall of the first support arm 31 to limit the position of the receiving plate 34.

[0032] In one embodiment, a frame 38 is fixedly installed on the outer wall of the first support arm 31. A second square hole 381 is opened on the side of the frame 38. A support frame 382 is fixedly installed on the side of the frame 38. A reset elastic member 383 is fixedly installed on the inner surface of the support frame 382. A collection rod 384 is fixedly installed at the end of the reset elastic member 383 away from the support frame 382. A pin block 385 is fixedly installed on the side of the collection rod 384. The pin block 385 is movably inserted into the inner cavity of the second square hole 381. A cross handle 386 is fixedly installed on the outer wall of the collection rod 384. The cross handle 386 is slidably connected to the inner wall of the support frame 382.

[0033] This design is for reference. Figure 7 When the threaded rod 33 is rotated, the arc-shaped clamping part 35 on the receiving plate 34 moves toward the arc-shaped clamping part 35 on the second support arm 32. The stepping strip plate 37 slides on the inner wall of the frame 38. The pin block 385 is provided with an inclined surface. The stepping strip plate 37 pushes the inclined surface, causing the pin block 385 to move toward the support frame 382. At the same time, it compresses the reset elastic element 383 to facilitate the feeding of the stepping strip plate 37. When the second square hole 381 corresponds to the first square hole 371, the elastic force of the reset elastic element 383 can drive the pin block 385 to be inserted into the first square hole 371, locking the reset action of the stepping strip plate 37. This prevents the receiving plate 34 from moving away from the cable and causing loosening, thus increasing safety. The locking state can be released by manually pulling the cross handle 386 for easy use.

[0034] In one embodiment, a hanging groove 11 is provided on the reference member 1, and a reinforcing foot 12 is fixedly installed on the outer wall of the reference member 1. The reinforcing foot 12 is fixedly installed on the outer wall of the connecting box 21.

[0035] This design is for reference. Figure 8 With the design of the hanging slot 11, when conditions permit, the user can suspend the reference part 1 from the hanging slot 11 and then perform the wire clamping operation, which is more convenient to use. With the design of the reinforcing foot 12, the connection between the connecting box 21 and the reference part 1 can be reinforced.

[0036] In one embodiment, the auxiliary operating mechanism 4 includes a support block 42, a strip-shaped through groove 41 is provided on the reference member 1, the support block 42 is fixedly installed on the inner wall of the strip-shaped through groove 41, a vent hole 43 is provided at the bottom of the support block 42, a contractile elastic member 44 is fixedly installed at the top of the support block 42, a sliding block 45 is fixedly installed at the top of the contractile elastic member 44, the sliding block 45 is slidably connected to the inner wall of the strip-shaped through groove 41, a limit rod 46 is fixedly connected to the top of the sliding block 45, and a handle 47 is fixedly sleeved on the outer wall of the limit rod 46.

[0037] This design is for reference. Figure 9When suspending the reference piece 1 from the hanging slot 11, the handle 47 is pressed down in advance, causing the limit rod 46 to move down and drive the sliding block 45 to slide in the strip groove 41. At the same time, the elastic element 44 is compressed and contracted, making the hanging slot 11 open. After suspension, the handle 47 is released, and the elastic force of the contracted elastic element 44 drives the handle 47 to return to its original position, closing the opening of the hanging slot 11 and preventing the problem of falling off.

[0038] In one embodiment, the auxiliary operating mechanism 4 further includes an internal threaded cylinder 48, which is fixedly installed on the top of the reference member 1. An external threaded block 481 is threadedly connected to the inner wall of the internal threaded cylinder 48. An alloy grip 482 is fixedly installed on the outer wall of the external threaded block 481. A limiting wing 483 is fixedly installed on the outer wall of the alloy grip 482. The number of limiting wings 483 is set to two. A rubber anti-slip sleeve 484 located between the two limiting wings 483 is fixedly sleeved on the outer wall of the alloy grip 482.

[0039] This design is for reference. Figure 10 The reference part 1 has no gripping position, which may be inconvenient for users with different habits. In this case, the external threaded block 481 can be rotated and connected to the internal threaded cylinder 48, and gripped from the outer wall of the alloy grip 482 for easy operation. After use, the alloy grip 482 can be disassembled and reused. The design of the rubber anti-slip sleeve 484 improves the stability when gripping the alloy grip 482.
