Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment and appliances technology, and in particular to a high-voltage test wiring clamp for substation equipment. Background Technology
[0002] As an indispensable core facility in the power system, power substation equipment undertakes critical tasks such as power transformation, distribution, control, and protection. Its core value lies in achieving efficient power transmission and safe, reliable application through precise voltage conversion. When conducting high-voltage tests on power substation equipment, the interconnection of cables must be completed according to regulations. This process requires the use of specialized wiring pliers as auxiliary tools to ensure operational safety and connection reliability.
[0003] Currently, most of the wiring clamps used for high-voltage testing of power equipment adopt the traditional clamp-shaped structure design. In actual operation, operators need to repeatedly open and close the wiring clamps multiple times to achieve the connection between the two cable ends, resulting in low overall wiring efficiency. Due to the limited lever arm length of the wiring clamps, operators need to expend a lot of force when carrying out wiring operations, resulting in a poor user experience and difficulty in achieving the desired results. Utility Model Content
[0004] This utility model relates to a high-voltage test wiring clamp for power equipment, which solves the problem that most of the existing wiring clamps used for high-voltage testing of power equipment adopt the traditional clamp-shaped structure design. In actual operation, the operator needs to repeatedly open and close the wiring clamp multiple times to achieve the connection between the two cable ends, resulting in low overall wiring efficiency.
[0005] In a first aspect, this utility model provides a high-voltage test wiring clamp for power equipment, specifically comprising: a main body, a fixed clamp head, a movable inner rod, a movable clamp head, a spring, clamp handles, and a transmission connecting rod; the fixed clamp head is welded to the end of the main body, the movable inner rod is connected inside the main body, and the movable clamp head is welded to the end of the movable inner rod; a spring is installed inside the main body, two clamp handles are connected to the outside of the main body, and a transmission connecting rod is connected to the outside of the clamp handles, the transmission connecting rod being connected to the movable inner rod.
[0006] Furthermore, the fixed jaw and the movable jaw are in sliding contact, and both the fixed jaw and the movable jaw are U-shaped with toothed ends.
[0007] Furthermore, the main body is provided with a guide hole, the movable inner rod is slidably connected in the guide hole provided in the main body, and a retaining ring is provided on the outside of the movable inner rod, the retaining ring being in contact with the inner side of the main body.
[0008] Furthermore, the clamp handle is rotatably connected to the main body, and the clamp handle rotation angle is 0~30 degrees.
[0009] Furthermore, one end of the transmission link is rotatably connected to the clamp handle, and the other end of the transmission link is rotatably connected to the movable inner rod. The movable inner rod is connected to the two clamp handles through the transmission link. The metal connector sleeve is located between the fixed clamp head and the movable clamp head. The ends of the two cables to be connected are inserted into the two ends of the metal connector sleeve. The two clamp handles are rotated inward, and the clamp handles drive the movable inner rod to move outward through the transmission link. The distance between the fixed clamp head and the movable clamp head decreases. The fixed clamp head and the movable clamp head apply pressure to the metal connector sleeve, crushing the metal connector sleeve and making the metal connector sleeve in close contact with the cable ends.
[0010] Furthermore, the clamp handle consists of a main handle and an outer sleeve. The outer sleeve is slidably connected to the outside of the main handle. The outer sleeve is provided with a sliding groove, which is L-shaped. A slider is provided inside the outer sleeve and is slidably connected to the sliding groove. By sliding the slider and the sliding groove together, the outer sleeve can be moved outward to extend the clamp handle, thereby increasing the lever arm and making the crimping wire connection operation more labor-saving and reducing the physical exertion of the workers.
[0011] Furthermore, the spring is fitted outside the movable inner rod, with one end of the spring contacting the inner side of the main body and the other end of the spring contacting the retaining ring provided on the movable inner rod. When the clamp handle is rotated inward, the spring is compressed and stores force. When the clamp handle is released, the movable inner rod moves inward and resets itself under the influence of the spring's thrust, increasing the distance between the fixed clamp head and the movable clamp head, thus separating the metal wire sleeve from the fixed clamp head and the movable clamp head.
[0012] This utility model provides a high-voltage test wiring clamp for power equipment, which has the following advantages:
[0013] When this utility model is in use, with the metal connector sleeve positioned between the fixed clamp head and the movable clamp head, the ends of the two cables to be connected are inserted into the two ends of the metal connector sleeve. Rotating the two clamp handles inward causes the movable inner rod to move outward via a transmission linkage, reducing the distance between the fixed clamp head and the movable clamp head. The fixed clamp head and the movable clamp head apply pressure to the metal connector sleeve, compressing it and ensuring close contact between the metal connector sleeve and the cable ends. This enables rapid wiring operations and ensures the stability of power transmission.
[0014] In addition, by sliding the slider and the groove together, the outer sleeve can be moved outward to extend the handle, thereby increasing the lever arm and making crimping wiring operations more labor-saving and reducing the physical exertion of workers. After use, the outer sleeve can be moved inward to shorten the handle, reducing the space occupied by the wiring pliers and making them easier to carry and store.
[0015] In addition, when the clamp handle is rotated inward, the spring is compressed and stores energy. When the clamp handle is released, the movable inner rod moves inward and resets itself under the influence of the spring force, increasing the distance between the fixed clamp head and the movable clamp head. This allows the metal wire sleeve to be separated from the fixed clamp head and the movable clamp head for other wiring operations, improving wiring efficiency.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1: Please refer to Figures 1 to 4 :
[0028] This utility model proposes a high-voltage test wiring clamp for substation equipment, comprising: a main body 1, a fixed clamp head 2, a movable inner rod 3, a movable clamp head 4, a spring 5, clamp handles 6, and a transmission link 7; the fixed clamp head 2 is welded to the end of the main body 1, the movable inner rod 3 is connected inside the main body 1, and the movable clamp head 4 is welded to the end of the movable inner rod 3; the spring 5 is installed inside the main body 1, and two clamp handles 6 are connected to the outside of the main body 1, and the transmission link 7 is connected to the outside of the clamp handles 6, and the transmission link 7 is connected to the movable inner rod 3; the fixed clamp head 2 and the movable clamp head 4 are in sliding contact, both of which are U-shaped, and the ends of the U-shaped parts of the fixed clamp head 2 and the movable clamp head 4 are toothed; a guide hole 101 is provided inside the main body 1, the movable inner rod 3 is slidably connected to the guide hole 101 provided in the main body 1, and a retaining ring 301 is provided outside the movable inner rod 3, which is in contact with the inside of the main body 1.
[0029] In this embodiment of the utility model, the clamp handle 6 is rotatably connected to the main body 1, the clamp handle 6 rotates at an angle of 0 to 30 degrees, one end of the transmission link 7 is rotatably connected to the clamp handle 6, and the other end of the transmission link 7 is rotatably connected to the movable inner rod 3. The movable inner rod 3 is connected to the two clamp handles 6 through the transmission link 7.
[0030] Using the above technical solution, when the metal connector sleeve is located between the fixed clamp head 2 and the movable clamp head 4, the ends of the two cables to be connected are inserted into the two ends of the metal connector sleeve. The two clamp handles 6 are rotated inward, and the clamp handles 6 drive the movable inner rod 3 to move outward through the transmission linkage 7. The distance between the fixed clamp head 2 and the movable clamp head 4 is reduced. The fixed clamp head 2 and the movable clamp head 4 apply pressure to the metal connector sleeve, crushing the metal connector sleeve and making the metal connector sleeve in close contact with the cable ends, realizing rapid wiring operation and ensuring the stability of power transmission.
[0031] In this embodiment of the utility model, the clamp handle 6 is composed of a main handle 61 and an outer sleeve 62. The outer sleeve 62 is slidably connected to the outside of the main handle 61. A sliding groove 6101 is provided on the outside of the outer sleeve 62. The sliding groove 6101 is L-shaped. A slider 6201 is provided inside the outer sleeve 62. The slider 6201 is slidably connected to the sliding groove 6101.
[0032] By adopting the above technical solution, the outer sleeve 62 can be moved outward through the sliding engagement of the slider 6201 and the sliding groove 6101, thereby extending the handle 6 and increasing the lever arm, making the crimping wiring operation more labor-saving and reducing the physical exertion of the workers. After use, the outer sleeve 62 can be moved inward to shorten the handle 6, reducing the space occupied by the wiring pliers and making them easier to carry and store.
[0033] In Example 2, based on Example 1, the spring 5 is fitted onto the outside of the movable inner rod 3, with one end of the spring 5 contacting the inside of the main body 1 and the other end of the spring 5 contacting the retaining ring 301 provided on the movable inner rod 3.
[0034] Using the above technical solution, when the clamp handle 6 is rotated inward, the spring 5 is compressed and stores force. When the clamp handle 6 is released, the movable inner rod 3 moves inward and resets itself under the influence of the spring 5. The distance between the fixed clamp head 2 and the movable clamp head 4 increases, so that the metal wire sleeve can be separated from the fixed clamp head 2 and the movable clamp head 4 for other wiring operations, thereby improving wiring efficiency.
[0035] The working principle of this embodiment is as follows: First, the outer sleeve 62 is moved outward to extend the handle 6, thereby increasing the lever arm and making the crimping and wiring operation more labor-saving and reducing the physical exertion of the workers. The metal connector sleeve is located between the fixed clamp head 2 and the movable clamp head 4. The ends of the two cables to be connected are inserted into the two ends of the metal connector sleeve. The two clamp handles 6 are rotated inward. The clamp handles 6 drive the movable inner rod 3 to move outward through the transmission linkage 7, reducing the distance between the fixed clamp head 2 and the movable clamp head 4. The fixed clamp head 2 and the movable clamp head 4 apply pressure to the metal connector sleeve, crushing it and making the metal connector sleeve in close contact with the cable ends, thus achieving a fast wiring operation. When the clamp handles 6 are rotated inward, the spring 5 is compressed and stores force. When the clamp handles 6 are released, the movable inner rod 3 moves inward and resets itself under the influence of the spring 5. The distance between the fixed clamp head 2 and the movable clamp head 4 increases, which can separate the metal connector sleeve from the fixed clamp head 2 and the movable clamp head 4. The outer sleeve 62 is moved inward to shorten the handle 6, reducing the space occupied by the wiring pliers and making them easier to carry and store.
