Description

Technical Field

[0001] The utility model relates to the technical field of charging springs, and in particular to a charger spring structure. Background Art

[0002] In daily life, charging electronic devices in cars has become a normal practice. The shrapnel structure of a car charger refers to the shrapnel part structure in a device used for vehicle charging. The shrapnel is usually made of metal and has a speaker socket shape. It can be inserted into the vehicle charging port to achieve power transmission.

[0003] However, the existing on-board charger shrapnel is connected to the circuit board by welding during production. Welding is a relatively simple and common connection method, but its welding quality is relatively low. Since parameters such as temperature and pressure are difficult to control during the welding process, the welding quality is unstable, and problems such as cold welding or short circuit of welding feet are prone to occur. Since the on-board charger needs to withstand frequent plugging and unplugging operations during use, this will cause fatigue of the welding points. After long-term use, the welding points may loosen, fall off or break, causing the charger to fail to work normally, posing a safety hazard. When the welding points are loose or fall off, abnormal current or short circuit may occur, thereby posing a safety hazard to the vehicle or charging equipment. Utility Model Content
