Description

A spring terminal to prevent swinging

technical field

    The utility model relates to the field of electronic components, in particular to a spring terminal, in particular to a spring terminal for preventing swing.

Background technique

Spring terminals are mainly used in electrical products such as electrical connectors and distribution cabinets. The products are widely used in lighting appliances, household appliances, connectors, automobile and motorcycle accessories, connectors, wiring harnesses, lamp holders, ballasts, lighting, lamps, Electronic instruments and other products. the

The structure of the plug spring terminal circulating on the market is mainly composed of a plug spring for inserting a male plug and a riveting foot for riveting the wire. After the male plug is inserted into the spring, it makes electrical contact. Since the plug spring is a cavity structure, the male plug will swing left and right when inserted into the cavity of the plug spring, which is prone to loosening, and the contact surface will be reduced when the electrical appliance is energized. When a large current occurs during work, the current will be unstable. Because the contact surface is small and not compact enough to withstand high voltage, it will seriously affect the conduction effect of the current, and at the same time affect the safety and stability of electrical products. the
