Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a wiring clamp spring piece assembly. Background Art

[0002] The straight-through self-locking spring terminal block is an accessory product commonly used in electrical connections. It is mainly used to achieve self-locking connections between electrical equipment without tightening screws. The self-locking function of the straight-through terminal block is mainly achieved through the terminal clamp spring assembly. According to customer feedback, the existing terminal clamp spring assembly is prone to deformation at the pressing point after frequent pressing to unlock and lock, resulting in loose locking of the terminal block and reduced locking efficiency. In addition, when the terminal clamp spring is connected to the terminal block, the structural strength is insufficient, resulting in the unstable and unreliable action of pushing the terminal block. Improvements and optimizations are made to this end. Utility Model Content
