Description

Technical Field

[0001] This utility model relates to the field of electronic fastener technology, specifically a reusable electronic fastener. Background Technology

[0002] Existing electronic products need to be fixed during the manufacturing process, and the current fixing method is to use bolts to fix them.

[0003] A low-loss electronic product connecting fastener disclosed in CN217328012U includes a top nut with a threaded rod fixedly installed on its outer wall. An outer groove is formed inside the top nut, and an inner cylinder is movably engaged within the outer groove. By twisting the inner cylinder, a limiting plate is transported from the outer wall's transverse groove to the top of the movable groove, causing the inner cylinder to move upwards. During this movement, the limiting plate extends into the interior and is engaged, causing the compression force on the spring to disappear, restoring the spring to its original shape. This allows the spring to extend the inner cylinder out from inside the top nut. The worker can then hold the inner cylinder, preventing it from being difficult to disassemble during thread stripping, thus saving time and improving work efficiency.

[0004] While existing fasteners can avoid the problem of stripped threads preventing disassembly, they are relatively difficult to disassemble. Therefore, we propose a reusable electronic fastener. Utility Model Content
