Modular PCB connecting structure and charging base thereof

Abstract

The invention relates to the technical field of electrical components, in particular to a modular PCB connecting structure, which comprises a PCB, an elastic ring piece and a terminal. A plurality of conductive electrifying holes are formed in the PCB, a mounting groove is formed in the end part of the terminal, the elastic ring piece is sleeved in the mounting groove, the maximum outer diameter of the elastic ring piece is larger than the aperture of the electrifying hole, and the elastic ring piece is elastic. The maximum outer diameter surface of the elastic ring piece abuts against the power-on hole. According to the novel connection structure of the PCB and the terminal, the structure is simpler, the assembling and plugging actions are simple, the novel connection structure is suitable for batch automatic assembling, the assembling efficiency is greatly improved, the power-on holes in the PCB facilitate plugging of parts on the two sides, assembly structure design is facilitated, meanwhile, the elastic connection structure is used, and the defect of loosening of welding spots is avoided, the fault-free service time of the product is effectively ensured, the production efficiency and the service life of the charging seat are effectively improved, and the market competitiveness of the product is improved.

Description

technical field [0001] The invention relates to the technical field of electrical components, in particular to a modular PCB board connection structure and a charging base thereof. Background technique [0002] With the popularity of electric vehicles, the charging stand suitable for electric vehicles has also undergone many improvements. However, there are still some problems with the existing charging base. The application of the PCB board greatly simplifies the circuit connection structure inside the charging base, but for the charging base manufacturer, each terminal needs to be crimped separately, and the wiring , The equivalent resistance between the PE and CC1 terminals needs to be wired and welded separately, the assembly process of employees is complicated, the assembly cycle is long, and it is not conducive to mass automatic production. During the use of the electric vehicle, the welding structure of the terminal and the PCB board has the risk of loosening of the ...

AI Technical Summary

Problems solved by technology

However, some problems still exist in some charging bases. The application of PCB greatly simplifies the circuit connection structure inside the charging base. , The equivalent resistance between PE and CC1 terminals needs to be wired and welded separately, the assembly process of employees is complicated, the assembly cycle is long, and it is not conducive to mass automatic production

During the use of the electric vehicle, the welding structure between the terminal and the PCB board may cause the solder joints to loosen due to long-term vibration, resulting in abnormal charging and affecting the use of the electric vehicle.
