Description

Technical Field

[0001] This invention relates to the field of contact material testing technology, and more specifically, to a system for testing the ablation resistance electrical properties of contact materials. Background Technology

[0002] Electrical contact materials refer to materials that conduct current (electrical signals, electrical energy) through mutual contact. During electrical contact, these materials must withstand the combined effects of electric arcs, electric fields, magnetic fields, forces, heat, and atmosphere to achieve their current conduction performance. With technological advancements, higher demands are placed on the electrical contact performance of electrical contact materials. Therefore, contact materials need to undergo ablation resistance electrical performance testing before use. Existing ablation resistance electrical performance testing equipment typically requires multiple tests on multiple contact materials of the same type to ensure testing effectiveness. This repeated disassembly and replacement leads to low testing efficiency, and there is a lack of suitable, efficient testing mechanisms. Furthermore, the protective cover used in the equipment protects the testing process, but its fixed installation makes internal maintenance cumbersome, and there is a lack of suitable protective cover adjustment mechanisms. Additionally, the equipment is prone to generating smoke during testing, and there is a lack of suitable, efficient smoke extraction mechanisms. Summary of the Invention

[0029] Please see Figures 1-4 A test system for the electrical properties of contact materials to resist ablation includes a workbench 1, a support 2 on the upper surface of the workbench 1, a control panel 3 on the top of the front surface of the support 2, a slide 4 slidably mounted inside the top of the support 2, and electrical connectors 5 penetrating on both sides of the lower surface of the slide 4, both of which are electrically connected to the control panel 3. A fixed seat 6 is mounted on the upper surface of the workbench 1, and limit seats 7 are symmetrically mounted on both sides of the upper surface of the fixed seat 6, with multiple sets of limit seats 7 spaced apart.

An adjustment mechanism is mounted inside the workbench 1 corresponding to the adjustment plate 9. A door 11 is hinged to the front surface of the workbench 1, and a handle 12 is mounted on the door 11.

[0030] In this embodiment, the slide block 4 drives the electrical connectors 5 on both sides to slide and adjust. The electrical connectors 5 and a certain contact material make contact to realize the contact material testing operation. After the contact material test is completed, the slide block 4 drives the electrical connectors 5 to slide to the position of another contact material to realize the detection adjustment.

[0031] More specifically, the adjustment mechanism adjusts the height of the adjustment plate 9, which is adjusted relative to the adjustment groove 10, thereby raising and lowering the protective cover 8, which facilitates the adjustment of the upper part of the workbench 1 for protection.

[0032] Please see Figure 4 As one embodiment of the slide block 4: a slide groove 13 is provided at the top of the bracket 2 corresponding to the slide block 4. A threaded rod 14 is rotatably provided inside the slide groove 13. The threaded rod 14 is threadedly connected to the slide block 4. The threaded rod 14 extends backward and passes through the bracket 2. A drive motor 15 is connected to the rear end of the threaded rod 14. The drive motor 15 is electrically connected to the control panel 3.

[0033] Specifically, by operating the control panel 3, the drive motor 15 is started, which drives the threaded rod 14 to rotate. The threaded rod 14 and the slide block 4 are threadedly engaged, and the slide block 4 slides relative to the slide groove 13 for adjustment.

[0034] Please see Figure 2 and Figure 3 As one implementation of the adjustment mechanism: the adjustment mechanism includes an adjustment motor 16 and an adjustment rod 17. The adjustment motor 16 is installed at the bottom of the workbench 1. The adjustment rod 17 is connected to the upper end of the adjustment motor 16. The adjustment rod 17 is rotatably connected to the inner wall of the top of the workbench 1. The adjustment rod 17 is threadedly connected to the adjustment plate 9. The adjustment motor 16 is electrically connected to the control panel 3. Guide rods 18 are symmetrically arranged inside the workbench 1. Guide holes 19 are opened on the adjustment plate 9 corresponding to the two guide rods 18.

[0035] Specifically, the control panel 3 controls the opening and closing of the regulating motor 16. When the regulating motor 16 is started, it drives the regulating rod 17 to rotate. The guide rod 18 and the guide hole 19 cooperate to guide the adjustment plate 9 to lift and lower.

[0036] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As one method of smoke extraction: smoke guide pipes 20 are provided on both the left and right sides of the upper surface of the workbench 1. A smoke extraction mechanism is connected to the upper end of the two smoke extraction pipes 23. The smoke extraction mechanism includes a housing 21, a fan 22, and smoke extraction pipes 23. The housing 21 is connected to the upper end of the two smoke guide pipes 20. The fan 22 is located in the center of the housing 21. Connecting rods 24 are provided between the fan 22 and the inner walls of the left and right ends of the housing 21. The smoke extraction pipes 23 are provided through the upper surface of the housing 21. The fan 22 is electrically connected to the control panel 3.

A dust extraction pipe 26 is provided through the bottom of one side of the housing 21. A dust extraction valve 27 is provided on the dust extraction pipe 26.

[0037] Specifically, by operating the control panel 3, the fan 22 is started. The fan 22 draws in the internal smoke through the smoke duct 20 and draws the smoke into the housing 21. The smoke is then discharged outward through the exhaust pipe 23. The dust cover 25 provides dust protection for the internal fan 22. For long-term use, the dust discharge valve 27 on the dust discharge pipe 26 is opened to discharge the internal dust and other debris outward.

[0038] In summary, the overall equipment is in use:

[0039] When in the installation state, multiple contact materials are installed on the corresponding fixed seat 6 and upper limit seat 7. After the contact materials are installed, the protective cover 8 is adjusted. The control panel 3 is operated to start the adjustment motor 16. The adjustment motor 16 drives the adjustment rod 17 to rotate. The adjustment rod 17 and the adjustment plate 9 are threaded together. The guide rod 18 and the guide hole 19 cooperate to guide, realizing the overall lifting and lowering adjustment of the adjustment plate 9 and the protective cover 8. The protective cover 8 and the bracket 2 cooperate to protect the test.

[0040] During testing, the control panel 3 is operated to start the drive motor 15. The drive motor 15 drives the threaded rod 14 to rotate. The threaded rod 14 and the slide 4 are threaded together. The slide 4 slides relative to the slide groove 13 to adjust. When it slides to a suitable position, the electrical connector 5 and the contact material make contact to achieve electrical performance testing. After the test of a certain contact material is completed, the drive motor 15 is started to adjust the slide 4 to make the electrical connector 5 contact another contact material to continue testing, thereby improving testing efficiency.

[0041] When in smoke exhaust mode, some contact materials are prone to ablation and smoke generation during the detection process. Control the control panel 3 to start the fan 22. The fan 22 sucks out the smoke generated inside through the smoke guide pipe 20 and discharges it to the outside through the smoke exhaust pipe 23, which facilitates the discharge of internal smoke, dust and other substances.
