[0008] Preferably, the shape of the special-shaped groove is adapted to the special-shaped area of the product. The special-shaped groove is a measurement area milled by machining for adapting to the special-shaped front surface of the product. Therefore, after the movable plate is pressed down, the thrust generated by the movable plate causes the conductor to be compressed downward and the conductor material to deform.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0018] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a high-voltage detection fixture for special-shaped products, including a fixed plate 1 and a movable plate 4. The movable plate 4 is located below the fixed plate 1. An insulating plate 5 is provided at the bottom of the movable plate 4, a conductor 6 is provided at the bottom of the insulating plate 5, a glass fiber insulator 7 is provided at the bottom of the conductor 6, and a special-shaped groove 8 is opened at the bottom of the glass fiber insulator 7.

[0020] As shown Figures 1-4 in Figure 1, symmetrically and fixedly connected to the top of the fixed plate 1 are cylinders 2, the output ends of the cylinders 2 penetrate through the fixed plate 1 and extend to the lower side. After the test starts, the cylinders 2 are operated, and after the cylinders 2 operate, the push rods 3 are driven to move downward.

[0021] As shown Figures 1-4 in Figure 2, fixedly connected to the output ends of the cylinders 2 are push rods 3, and the lower end faces of the two push rods 3 are fixedly connected to the top of the movable plate 4. The push rods 3 drive the movable plate 4 to move downward, and the movable plate 4 can drive the insulating plate 5, the conductor 6, and the fiberglass insulator 7 to move downward and press on the surface of the product.

[0022] As shown Figures 1-4 in Figure 3, the shape of the special-shaped groove 8 is adapted to the special-shaped area of the product. With the arrangement of the special-shaped groove 8 on the surface of the fiberglass insulator 7, the special-shaped groove 8 is a measurement area milled by machining for adapting to the special-shaped front of the product. Therefore, after the movable plate 4 is pressed downward, the thrust generated by the movable plate 4 causes the conductor 6 to be compressed downward and the material of the conductor 6 to deform.

[0023] As shown Figures 1-4 in Figure 4, the fiberglass insulator 7 and the insulating plate 5 are provided in a matching manner. The deformed material of the conductor 6 extrudes from the fiberglass insulator 7 and contacts the object to be detected, completing the high-voltage detection of the product.

[0024] The usage method and working principle of this device: When the top surface of a special-shaped product is subjected to a high-voltage insulation test using the detection fixture, through the combined use of the insulating plate 5, the conductor 6, and the fiberglass insulator 7, they are pressed and attached to the surface of the product for testing. After the test starts, the cylinders 2 are operated, and after the cylinders 2 operate, the push rods 3 are driven to move downward. The push rods 3 drive the movable plate 4 to move downward, and the movable plate 4 can drive the insulating plate 5, the conductor 6, and the fiberglass insulator 7 to move downward and press on the surface of the product. At this time, with the arrangement of the special-shaped groove 8 on the surface of the fiberglass insulator 7, the special-shaped groove 8 is a measurement area milled by machining for adapting to the special-shaped front of the product. Therefore, after the movable plate 4 is pressed downward, the thrust generated by the movable plate 4 causes the conductor 6 to be compressed downward and the material of the conductor 6 to deform. The deformed material of the conductor 6 extrudes from the fiberglass insulator 7 and contacts the object to be detected, completing the high-voltage detection of the product. During the detection process, the special-shaped groove 8 is opened on the easily machined fiberglass insulator 7, and the principle of high-voltage creepage distance is used to make the conductor 6 deform and fit the detected product to complete the high-voltage detection. Compared with the traditional method of processing the conductor 6, the problem of difficult processing of the conductor 6 is effectively solved.
