AI Technical Summary

Technical Problem

In existing technologies, the welding process between the terminals and integrated circuit boards in the electrical systems of new energy vehicles relies on manual operation, resulting in low production efficiency, easy welding defects, fragmented processes, and cumbersome procedures.

Method used

It adopts an electronic control component, including a housing, wiring terminals, auxiliary parts and an integrated circuit board. By setting a positioning part and a positioning through groove, it can achieve integrated pre-positioning and fixing in one assembly. The elastic limiting structure of the auxiliary parts and the positioning protrusion and groove sleeve connection ensure the stable positioning of the contact foot, and cooperate with the automated robot arm for welding.

Benefits of technology

This technology enables efficient integration, positioning, and fixing of terminal blocks and integrated circuit boards, simplifies the assembly process, improves production efficiency and welding connection reliability, and avoids welding defects caused by manual insertion.

Abstract

The application discloses an electric control assembly and a welding method of an integrated circuit board. The electric control assembly is suitable for assembling the integrated circuit board provided with a fourth positioning part and at least one plug-in hole. The electric control assembly comprises a box body, a wiring terminal and an auxiliary part. The box body is provided with a first positioning part and a second positioning part. The wiring terminal is provided with a terminal body and at least one contact pin connected with the terminal body. The terminal body is installed on the box body. The auxiliary part is provided with a third positioning part and at least one positioning through slot. The auxiliary part is connected with the corresponding contact pin through the positioning through slot, so that the contact pin is arranged on the opposite sides of the auxiliary part. The auxiliary part is connected with each other through the third positioning part and the first positioning part, so as to fix the posture of the contact pin. The integrated circuit board is suitable for being positioned through the fourth positioning part and the second positioning part, so that the plug-in hole is positioned and connected with the corresponding contact pin. The box body, the wiring terminal and the integrated circuit board can be integrated and positioned and fixed in one assembling process, and the efficiency is improved.
