Abstract
Description
Technical Field
[0001] This utility model relates to the field of switchgear clamp technology, specifically a wiring clamp for high-voltage switchgear. Background Technology
[0002] During the operation and maintenance of high-voltage switchgear, the proper arrangement and fixation of internal wiring is crucial. High-voltage switchgear typically integrates a large number of electrical lines, which are not only numerous but also complex in their routing. It is necessary to ensure that these lines are arranged in an orderly manner within the confined space of the cabinet to avoid mutual interference and entanglement between lines, prevent safety accidents such as short circuits and leakage caused by loose or messy wiring, and ensure the stable operation of the power system.
[0003] Traditional cable fixing methods often employ simple cable ties or ordinary wire clamps. However, cable ties have significant drawbacks. Cable ties are disposable, making it extremely inconvenient to adjust the cable routing or replace cables, and they can also generate a large amount of waste cable ties, which is not environmentally friendly. While ordinary wire clamps improve the fixing effect to some extent, they are mostly simple in structure, have limited function, and lack flexibility and adjustability. For example, when faced with cables of different specifications and routings, it is difficult to precisely adjust the clamping force and clamping range according to actual needs, making them unsuitable for the complex and ever-changing cable layout scenarios within high-voltage switchgear. Therefore, a cable clamp for high-voltage switchgear is proposed to solve the above problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The purpose of this utility model is to address the shortcomings of traditional cable ties and ordinary wire clamps, which are often used for fixing wiring. Cable ties have significant drawbacks: they are disposable, making it extremely inconvenient to adjust or replace wiring, and they can also generate a large amount of waste, which is not environmentally friendly. While ordinary wire clamps improve the fixing effect to some extent, they are mostly simple in structure, have limited function, and lack flexibility and adjustability. For example, when dealing with wiring of different specifications and routes, it is difficult to accurately adjust the clamping force and clamping range according to actual needs, making it unsuitable for the complex and ever-changing wiring layout in high-voltage switchgear. Therefore, this utility model proposes a wiring clamp for high-voltage switchgear.
[0006] (II) Technical Solution
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0008] A wiring clamp for a high-voltage switchgear includes a base plate. Two long L-shaped support plates are fixedly connected to the top of the base plate. A first hinge shaft is provided between the two long L-shaped support plates. Two short L-shaped support plates are rotatably connected to the outer side of the first hinge shaft. A second hinge shaft is rotatably connected to the inner side of each of the two short L-shaped support plates. The two second hinge shafts are fixed together by a block. A cylindrical connector is rotatably connected between the two long L-shaped support plates. An adjustment mechanism for adjusting the relative distance between the two short L-shaped support plates and the base plate is provided between the cylindrical connector and the block. A clamping gap is formed between the two long L-shaped support plates and the two short L-shaped support plates.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Preferably, the adjusting mechanism includes a screw, the inner side of the cylindrical connector is threaded with the screw, the screw is rotatably limited and connected to the inner side of the block, the upper end of the screw has a through hole, and a pin is inserted into the inner side of the through hole.
[0011] Preferably, one end of the pin is provided with a bent portion.
[0012] Preferably, the two long L-shaped support plates are fixedly connected by a connecting column.
[0013] Preferably, the base plate has a plurality of threaded holes.
[0014] (III) Beneficial Effects
[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0016] This invention eliminates the need for cable ties for fixing by setting an adjustment mechanism, unlike existing technologies. Furthermore, the clamping force can be adjusted by rotating the adjustment mechanism to adjust the relative distance between the two short and long L-shaped support plates and the base plate, thus avoiding damage to the insulation layer.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] In the embodiments, by Figure 1 and Figure 2 A wiring clamp for a high-voltage switchgear is provided, comprising a base plate 1, two long L-shaped support plates 2 fixedly connected to the top of the base plate 1, a first hinge shaft 3 disposed between the two long L-shaped support plates 2, two short L-shaped support plates 4 rotatably connected to the outer side of the first hinge shaft 3, and a second hinge shaft 5 rotatably connected to the inner side of each of the two short L-shaped support plates 4, the two second hinge shafts 5 being fixed together by a block 6, a cylindrical connector 7 rotatably connected between the two long L-shaped support plates 2, and an adjustment mechanism 8 for adjusting the relative distance between the two short L-shaped support plates 4 and the base plate 1 disposed between the cylindrical connector 7 and the block 6, forming a clamping gap between the two long L-shaped support plates 2 and the two short L-shaped support plates 4.
[0022] With the above setup, the operator places the cable in the clamping gap above the base plate 1 (i.e., the space between the two long L-shaped support plates 2 and the two short long L-shaped support plates 4). At this time, the short long L-shaped support plates 4 are rotatably connected to the long L-shaped support plates 2 through the first hinge shaft 3, so that the short long L-shaped support plates 4 can be unfolded outward to facilitate the insertion of the cable. The relative distance between the two short long L-shaped support plates 4 and the base plate 1 is adjusted by the rotation adjustment mechanism 8, thereby reducing the clamping gap and pressing the cable. Compared with the prior art, there is no need to use cable ties for fixing, and the clamping force is adjusted by the adjustment mechanism 8 to avoid damage to the insulation layer.
[0023] Reference Figure 1 and Figure 2 The adjusting mechanism 8 includes a screw 81, and the inner side of the cylindrical connector 7 is threaded with the screw 81. The screw 81 is rotated and limited to the inner side of the block 6. The upper end of the screw 81 is provided with a through hole 82, and a pin 83 is inserted into the inner side of the through hole 82.
[0024] With the above structural setup, the pin 83 is inserted into the through hole 82 at the top of the screw 81, serving as the force point for the rotating lever. The operator holds both ends of the pin 83, preparing to apply rotational force, and rotates the screw 81 clockwise while holding the pin 83. Since the screw 81 engages with the inner thread of the cylindrical connector 7, and the end of the screw 81 is threaded into the inner threaded hole of the block 6, when rotating, the screw 81 pushes the block 6 to move away from the cylindrical connector 7 along the axis; when rotating the screw 81 counterclockwise, the block 6 moves closer to the cylindrical connector 7. The block 6 drives the two short and long L-shaped support plates 4 to rotate inward or outward around the first hinge axis 3 via the second hinge shaft 5, thereby reducing or increasing the clamping gap. When the clamping gap is adjusted to suit the cable size, the rotation of the pin 83 is stopped. The threaded self-locking feature automatically fixes the screw at position 81 without the need for an additional locking device. The cable can be pulled to confirm that there is no looseness or overtightness, ensuring that the clamping force is evenly distributed and does not damage the insulation layer.
[0025] Reference Figure 1 and Figure 2 One end of the pin 83 is provided with a bent portion;
[0026] With the above structural design, the bent portion can be prevented from dislodging from the through hole 82 during the rotation of the pin 83.
[0027] Reference Figure 1 and Figure 2 The two long L-shaped support plates 2 are fixedly connected by a connecting column 9.
[0028] The above structural design can enhance the relative stability between the two long L-shaped support plates 2.
[0029] Reference Figure 1 and Figure 2 The base plate 1 has several threaded holes 10.
[0030] With the above-described structure, the entire device can be installed inside the high-voltage switchgear using threaded holes 10 and bolts.
