Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A voltage sensor testing fixture structure includes a base plate 100, on which a high-voltage electrical connection box 101 is fixedly mounted. A transparent cover 102 is fixedly mounted on the high-voltage electrical connection box 101. A placement groove 103 is formed on the top side of the base plate 100, and a positioning block 104 is arranged in the placement groove 103. A voltage sensor 200 is placed in the placement groove 103. High-voltage wiring slots 105 and connecting sleeves 300 are fixedly mounted on both sides of the high-voltage electrical connection box 101, respectively. A movable probe 301 is slidably mounted on the connecting sleeve 300. The movable probe 301 is connected to the test terminal of the voltage sensor 200. The connection between the voltage sensor 200 and the high-voltage wiring slot 105 is isolated by the high-voltage electrical junction box 101 and the transparent cover 102, so that the operator can avoid contact with the high-voltage part, thereby improving the safety of the voltage sensor test fixture. The movable probe 301 inside the connecting sleeve 300 is only energized when the voltage sensor 200 is in the appropriate position, and is normally in a non-energized state, which further ensures the safety of the voltage sensor test fixture.

[0018] In an optional embodiment: two movable clamping plates 400 are slidably installed on the side of the high-voltage electrical connection box 101, and each of the two movable clamping plates 400 is provided with an arc-shaped slot 408.

[0019] It should be noted that after the movable clamp 400 is combined, the cable can be clamped by the arc-shaped slot 408 to prevent the staff from coming into contact with the live parts during use.

[0020] In an optional embodiment: a drive rod 403 is rotatably mounted on the side of the movable clamping plate 400, and the same operating handle 405 is rotatably mounted on the two drive rods 403. A drive shaft 404 is rotatably mounted on both ends of the drive rods 403, and the two drive shafts 404 are fixedly mounted on the movable clamping plate 400 and the operating handle 405.

[0021] It should be noted that the operating handle 405 drives the movable clamp 400 to move through the cooperation of the drive rod 403 and the drive shaft 404. After the movable clamp 400 opens, the cable can be connected.

[0022] In an optional embodiment: two return springs 407 are fixedly installed on the operating handle 405, and the same fixing block 406 is fixedly installed on the two return springs 407. The fixing block 406 is fixedly installed on the high voltage electrical connection box 101.

[0023] It should be noted that the position of the operating handle 405 is restricted by the fixing block 406 and the return spring 407, ensuring that the movable clamping plates 400 have a driving force to move closer to each other.

[0024] In an optional embodiment: a limiting groove 401 is provided on the movable clamping plate 400, and a limiting rail 402 is slidably installed in the limiting groove 401. The limiting rail 402 is fixedly installed on the side of the high-voltage electrical connection box 101.

[0025] It should be noted that the position of the movable clamp 400 is limited by the limiting slide rail 402 and the limiting slide groove 401, and can only move within a fixed range.

[0026] In an optional embodiment: an electrical contact 302 is fixedly installed inside the connecting sleeve 300, and the electrical contact 302 is adapted to the movable probe 301.

[0027] It should be noted that for the voltage sensor 200 to detect, the detection interface of the voltage sensor 200 needs to be in contact with the movable probe 301, and the movable probe 301 needs to be pushed to contact the electrical contact 302.

[0028] In an optional embodiment: one end of the movable probe 301 extending into the connecting sleeve 300 is fixedly sleeved with an annular sleeve 303, the annular sleeve 303 is slidably installed in the connecting sleeve 300, one end of a buffer spring 304 is fixedly installed on the annular sleeve 303, and the other end of the buffer spring 304 is fixedly installed on the inner wall of the connecting sleeve 300.

[0029] It should be noted that the movement of the movable probe 301 is restricted by the annular sleeve 303 and the buffer spring 304, so that the movable probe 301 moving inside the connecting sleeve 300 will only be energized when the voltage sensor 200 is in the appropriate position, and is normally in a non-energized state, which further ensures the safety of the voltage sensor testing fixture.

[0030] Working principle of this utility model: When using this device, the cable must first be connected to the high-voltage wiring slot 105. The operating handle 405 is then moved to its current position. The operating handle 405, through the cooperation of the drive rod 403 and the drive shaft 404, drives the movable clamping plate 400 to its current position. Once the movable clamping plate 400 opens, the cable can be connected. When the movable clamping plate 400 closes, the cable can be clamped by the arc-shaped slot 408, preventing the operator from contacting live parts during use. The position of the movable clamping plate 400 is limited by the limiting slide rail 402 and the limiting slide groove 401, and can only move within a fixed range. The operating handle 405... The position is restricted by the fixed block 406 and the return spring 407, ensuring that the movable clamping plates 400 have a driving force to move closer to each other. The detection of the voltage sensor 200 requires that the detection interface of the voltage sensor 200 contact the movable probe 301 and push the movable probe 301 to contact the energized contact 302. The movement of the movable probe 301 is restricted by the annular sleeve 303 and the buffer spring 304, so that the movable probe 301 moving inside the connecting sleeve 300 will only be energized when the voltage sensor 200 is in a suitable position, and is normally in a non-energized state, which further ensures the safety of the voltage sensor testing fixture.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
