[0048] As Figure 1 and 2 shown, there is provided an electrical test device for the terminal of a cable accessory device, including an electrical measurement system and a tooling system.

[0049] The electrical measurement system is composed of a grading shield 110, a controllable terminal 120, a simulated cable 130, a vertical sliding table module 140, a controllable component 150, and an elastic terminal 160. Among them, the grading shield 110 is used to evenly distribute the electric field and prevent partial discharge from occurring. The controllable terminal 120 is used to connect the simulated cable 130 and the high-voltage power distribution equipment. The simulated cable 130 is used to test the cable accessory. The vertical sliding table module 140 is used to simulate the movement of the simulated cable 130 in the vertical direction. The controllable component 150 is used to evenly distribute the electric field at the insulating shield end of the simulated cable 130. The elastic terminal 160 is used to connect the conductor of the simulated cable 130.

[0050] The voltage equalizing cover 110 is electrically connected to the top end of the response control terminal 120 and the two are fixed. The bottom end of the response control terminal 120 is electrically connected to the simulation cable 130. The bottom end of the simulation cable 130 is electrically connected to the elastic terminal 160. The response control component 150 is fixedly arranged on the simulation cable 130 near the elastic terminal 160, and the shell of the response control component 150 is fixedly installed on the slider of the vertical sliding table module 140. Through the movement of the vertical sliding table module 140 in the vertical direction, the movement of the simulation cable 130 in the vertical direction is realized.

[0051] The tooling system consists of an epoxy plug 210, a sliding table bracket 220, a stepping motor 230, a tooling bracket 240, a slide rail 250, an elastic contact 260, a double-pass sleeve 270, and a current-carrying contact 280. Among them, the epoxy plug 210 is used to seal the connection point of the terminal of the cable accessory device to be tested (i.e., the product under test) to ensure the insulation performance of the connection. The sliding table bracket 220 is used to install and fix the epoxy plug 210. The stepping motor 230 is used to drive the sliding table bracket 220 and the epoxy plug 210 and the current-carrying contact 280 thereon to realize automatic operation. The tooling bracket 240 is used to install and fix the test tooling. The slide rail 250 is used for the sliding table bracket 220 to realize linear motion. The elastic contact 260 is used to connect the elastic terminal 160. The double-pass sleeve 270 is used to install the terminal of the cable accessory device to be tested (i.e., the product under test). The current-carrying contact 280 is used to connect the epoxy plug 210.

[0052] Elastic contacts 260 are arranged at both ends of the sleeves on the left and right sides of the double-pass sleeve 270. The first connection channel of the cable accessory device terminal 001 (i.e., the first product under test) is sleeved on the left sleeve of the double-pass sleeve 270, and the first connection channel of the cable accessory device terminal 002 (i.e., the second product under test) is sleeved on the right sleeve of the double-pass sleeve 270. Therefore, electrical tests can be performed on two products under test simultaneously. It should be noted that in the present utility model, by increasing the number of the ends of the sleeve, the number of products under test that can be electrically tested simultaneously can be increased.

[0053] Therefore, the double-pass sleeve 270 is fixedly arranged at the middle position of the tooling bracket 240, and the two epoxy plugs 210 are respectively arranged on the left and right sides of the double-pass sleeve 270.

[0054] The epoxy plug 210 is fixedly installed on the slide bracket 220. The slide bracket 220 is in threaded fit with the lead screw, and the slide bracket 220 is slidably connected to the slide rail 250. The slide rail 250 is arranged along the radial direction of a circle with the double-pass sleeve 270 as the center. The arrangement direction of the lead screw is the same as that of the slide rail 250. Then, the lead screw is rotated by the stepper motor 230, so that the slide bracket 220 moves along the slide rail 250, driving the epoxy plug 210 to approach or move away from the double-pass sleeve 270. The two stepper motors 230 are respectively fixedly arranged on the left and right sides of the tooling bracket 240.

[0055] The sleeve ends on both the left and right sides of the double-pass sleeve 270 are connected to the elastic contacts 260. The first connection channel of the product to be measured is sleeved on the sleeve of the double-pass sleeve 270. Then, the elastic contacts 260 are located in the connection channel of the product to be measured.

[0056] The end of the epoxy plug 210 is connected to the current-carrying contact 280. The epoxy plug 210 and the current-carrying contact 280 extend into the third connection channel of the product to be measured. Then, the current-carrying contact 280 is located in the connection channel of the product to be measured.

[0057] As can be seen from the above, this embodiment is equipped with a set of tooling system and two sets of electrical measurement systems. The two sets of electrical measurement systems are used to simultaneously perform electrical tests on the cable accessory equipment terminal 001 (i.e., the product to be measured 1) and the cable accessory equipment terminal 002 (i.e., the product to be measured 2).

[0058] The simulated cable 130 and the elastic terminal 160 of the electrical measurement system move in the vertical direction, so that the simulated cable 130 and the elastic terminal 160 extend into the second connection channel of the product to be measured. Then, the elastic terminal 160 is located in the connection channel of the product to be measured.

[0059] Finally, the elastic terminal 160, the current-carrying contact 280, and the elastic contact 260 are connected to each other. After the connection is completed, the electrical switch is started to perform an electrical test, so as to detect the electrical performance of the cable accessory equipment terminal.

[0060] The working process of this embodiment is further described below:

[0061] The cable accessory equipment terminals (001, 002) to be measured are respectively installed on both sides of the double-pass sleeve 270, and the vertical slide module 140 and the slide bracket 220 perform automated operations. The elastic terminal 160, the elastic contact 260, and the current-carrying contact 280 are tightly connected to ensure the reliability of the electrical connection. The response control terminal 120 is started and connected to the high-voltage power distribution equipment to perform an electrical test on the cable accessory equipment terminals (001, 002). The voltage equalizing cover 110, the response control terminal 120, and the response control component 150 are used to ensure the safety and accuracy of the test.

[0062] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any person skilled in the art can, without departing from the scope of the technical solution of the present utility model, make many possible changes and modifications to the technical solution of the present utility model by using the methods and technical contents disclosed above, or modify it into equivalent embodiments with equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present utility model without departing from the content of the technical solution of the present utility model shall be covered by the protection scope of the present utility model.
