Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology for launch vehicles, specifically to an energized vibration clamp for socketless electromagnets. Background Technology

[0002] As an electrical component, DC electromagnets must not only operate stably at room temperature but also ensure the normal functioning of the controlled moving parts under high temperature, low temperature, vibration, and low air pressure conditions. To verify the performance of an electromagnet under vibration conditions, it is necessary to monitor its current and resistance changes during vibration. Since socketless electromagnets lack a stable socket or plug connection, alligator clips are typically used to connect them to the energized parts (such as metal contact pieces) when powered on. However, these alligator clips can detach during vibration, causing abnormalities or interruptions in the test. Therefore, a special clamp needs to be designed to ensure the stability of the energized electromagnet during vibration, avoiding reduced product reliability due to unstable connections.

Two copper sleeve spring assemblies 4 are inserted into each product fixing slot 13.

[0039] See appendix Figure 9 , Figure 9 The main structure of a copper sleeve spring assembly is illustrated exemplarily. Figure 9As shown, the main function of the copper sleeve spring assembly 4 is to electrically connect the electromagnet to the energized equipment. The copper sleeve spring assembly 4 includes a copper sleeve 41 with a through hole at its rear end. A pressure plate 42 is connected to the front end of the copper sleeve 41.

[0042] The present invention provides a method for using an energized vibration clamp for socketless electromagnets.

[0043] (1) Assemble the pressure block 3, copper sleeve spring assembly 4, terminal block 16, and protection plate 15. Usually, this process only requires one installation and does not require repeated disassembly and assembly during use.

[0044] (2) Pre-install the base plate 1, support block 2 and pressure block 3, that is, pre-assemble the base plate 1, support block 2 and pressure block 3 together with nails 11 and wing nut assembly 18. The screws 11 and wing nut assembly 18 can be connected by hand with slight tightening.

[0045] (3) Fix product 19, that is, install the terminal block electromagnet into the fixture, fix the product through the base plate 1, and limit the position of the support block 2 and the pressure block 3 to ensure that the product will not swing during vibration.

[0046] (4) Tighten the base plate 1, support block 2 and pressure block 3, that is, check that the contacts in the copper sleeve spring assembly 4 are in close contact with the terminal piece, and then tighten the base plate 1, support block 2 and pressure block 3 to ensure stability during vibration.

[0047] (5) Fix the fixture to the vibration table, that is, fix the assembled product and vibration fixture to the vibration table, connect the power supply to the terminal block, and then observe the product performance in the vibration environment.

[0048] In summary, the energized vibration clamp for socketless electromagnets provided by this utility model can realize the functions of fixing, clamping, and energizing the terminal block type electromagnet. To improve production efficiency, the clamp can simultaneously fix multiple products and perform energization testing. Specifically, the base plate, support block, and pressure block are interconnected to form the clamp's support structure; the copper sleeve spring assembly and terminal block are used to connect the product to the energized equipment, forming the product's energization structure; and the protective plate is used to conceal the electrodes and wires, forming a circuit protection structure.

[0049] This utility model provides an energized vibration clamp for non-socket electromagnets. This energized vibration clamp is suitable for energized vibration clamps for non-socket electromagnets. By converting the unstable energized position of the electromagnet into a fixed and reliable socket-type energization method, it enables monitoring of electromagnet performance during vibration of multiple products, avoiding test interruptions caused by unstable power connections. This results in a 99% first-pass yield rate, improving the stability and reliability of the vibration testing process for this type of electromagnet, significantly reducing the waste of manpower and resources caused by repeated tests due to test errors, and shortening the product production cycle.
