[0002] Cables connect electronic equipment on spacecraft, and insulation testing of these cables is required before each test and launch. Currently, this method is often performed manually using a pinhole wire to test the insulation resistance between each point on a cable connector.

Patent document CN206209051 U discloses an expandable cable insulation tester for measuring the insulation properties of a cable under test by plugging it into a cable connector under test via the cable connector. The tester includes an upper measurement hole, a lower measurement hole, an upper expansion hole, a lower expansion hole, an expansion line, and several bidirectional switches. The bidirectional switches are electrically connected to correspondingly numbered test points on the cable connector under test. Each bidirectional switch is electrically connected to both an upper measurement hole and a lower measurement hole. While the tester can perform insulation testing on cable connectors with up to 128 cores, it cannot meet the requirements for cable insulation testing and cannot be replaced or repaired if a bidirectional switch fails.

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Combine Figure 1An expandable cable insulation tester includes a tester body 1, a connector 2 is installed through the left side of the top of the tester body 1, a plurality of bidirectional switches 3 are arranged on the top of the tester body 1, an upper measuring hole 4 is opened through the right side of the top of the tester body 1, a lower measuring hole 5 is opened through the right side of the top of the tester body 1, an upper expansion hole 6 and a lower expansion hole 7 are opened through the left and right sides of the tester body 1, and a disassembly component A is arranged inside the tester body 1.

[0019] The expandable cable insulation tester of the present invention is scalable. When there is more than one cable connector to be tested, multiple tester bodies 1 can be flexibly spliced ​​according to needs to quickly realize the simultaneous measurement of the insulation between multiple connector points. In addition, the tester body 1 is small in size, simple to understand and easy to operate. It can be used in the aerospace field to effectively improve the efficiency of cable insulation measurement.

[0020] Combine Figures 2 to 4 The disassembly component A includes a sleeve 8, the top of the sleeve 8 is rotatably connected to the two-way switch 3, a sliding groove 9 is opened inside the sleeve 8, a card slot 10 is opened through the left side of the sleeve 8, a sliding rod 11 is slidably connected inside the card slot 10, and a spring 12 is slidably connected to the outside of the sliding rod 11, a stopper 13 is fixedly connected to the left side of the sliding rod 11, and a card block 14 is fixedly connected to the right side of the sliding rod 11. The two ends of the spring 12 are respectively fixedly connected to the surfaces of the stopper 13 and the card block 14, a hemispherical head 15 is slidably connected inside the sliding groove 9, and a connecting column 16 is fixedly connected to the bottom of the hemispherical head 15. A sliding disk 17 is slidably sleeved on the outside of the connecting column 16, and a base 18 is fixedly connected to the bottom of the inner wall of the tester body 1.

[0021] The purpose of clamping, unlocking and disassembling the sleeve 8 is achieved by the sliding rod 11, spring 12, stop block 13 and clamping block 14. At the same time, the special structure of the hemispherical head 15 and the sliding disk 17 is matched with the clamping block 14, so that the clamping block 14 can be freely operated. The structure is simple and convenient, the operability is strong, and the practicality is high.

[0022] Working principle: When in use, when the two-way switch 3 fails and cannot be detected, turn off the two-way switch 3 and press the sleeve 8 downward at the same time. The block 14 slides inside the sliding groove 9 to the top of the sliding disk 17. Due to the special shape of the block 14, the block 14 squeezes the spring 12 to the left and slides to the bottom of the sliding disk 17. At this time, the sleeve 8 is lifted upward, and the block 14 drives the sliding disk 17 to slide on the connecting column 16 to the bottom of the hemispherical head 15. The inner groove of the hemispherical head 15 coincides with the upper half of the sliding disk 17, so that the block 14 slides to the half After it is under the ball head 15, it is squeezed to compress the spring 12 to the left, and at the same time, it slides to the top of the hemispherical head 15, takes out the sleeve 8, and the sliding disk 17 slides to the top of the base 18 due to its own gravity, and replaces and repairs the two-way switch 3. After the replacement is completed, the sleeve 8 is aligned with the hemispherical head 15 and pressed downward. The block 14 is squeezed to compress the spring 12 to the left, and at the same time slides to the bottom of the hemispherical head 15. The spring 12 loses pressure and pushes the block 14 out to the right. The block 14 is stuck under the hemispherical head 15 to complete the installation and continue to work. The structure is convenient and simple, and it is highly practical.

[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
