AI Technical Summary
Existing metal terminals are prone to detachment due to external vibration or force in harsh environments, leading to circuit breakage. Furthermore, if the protruding structure is too tight, it is difficult to disassemble, posing safety hazards and damage risks.
A self-locking hardware terminal was designed. By setting a spring and a triangular protrusion inside the housing, the self-locking function is achieved by the deformation of the spring. The connection stability is improved by combining the inner protrusion plate and the side protrusion plate, and the disassembly can be achieved by pressing the pressure plate.
It achieves the stability of electrical connection under external force, while facilitating the disassembly and installation of the interface and avoiding damage caused by the protruding structure.
