Connecting reed structure

Abstract

The invention provides a connecting reed structure, which includes a reed body portion (63). The reed body portion (63) is an inverted S-shaped structure. A fixed connecting structure is formed between the reed body portion (63) and an external connecting portion (61). A planar welding mating surface (66) is formed on the bottom end of the reed body portion (63). The welding mating surface facilitates the installation and fixation of a connecting reed itself. The external connecting portion facilitates the connection between the connecting reed and other parts. The reed body portion is designed into an inverted S-shaped structure, so that the connecting reed forms a damping vibration attenuation system. Compared with the traditional soldering and other strong connections, the connecting portion of the connecting reed can be prevented from falling off, so that the risk of vibration failure of the connecting reed is greatly reduced, and the requirement for automatic surface mounting operation of the connecting reed can be better met. The connecting reed structure has outstanding advantages such as convenient installation and reliable vibration attenuation.

Description

technical field [0001] The invention relates to the field of reed structure design, in particular to a connection reed structure used for vibration reduction of electronic water pumps. Background technique [0002] The electronic water pump used in automobiles is mainly composed of a motor, an electric control part and a water conservancy part. The electric control part is formed by connecting various electronic components on the PCB. The electrical connection and signal transmission between the motor and the controller are mainly through Soldering is performed. However, this soldering is prone to the following problems: [0003] First, the welding surface is easy to oxidize at high temperature, which can easily lead to local poor contact and make the electronic water pump work abnormally. [0004] Second, the weld is a strong connection. During the working process of the electronic water pump, the electronic water pump itself is also in a vibration environment, and it is ...

AI Technical Summary

Problems solved by technology

[0003] First, the welding surface is easy to oxidize at high temperature, which can easily lead to local poor contact and make the electronic water pump work abnormally

[0004] Second, the weld is a strong connection. During the working process of the electronic water pump, the electronic water pump itself is also in a vibrating environment, and it is easy to cause connection failure due to vibration, which makes the electronic water pump work abnormally.

[0005] Third, since the connection of various electronic components on the PCB is done through automated patching, and the PCB needs to go through a high-temperature furnace to complete the soldering operation after the PCB is patched. During this process, the flow of tin liquid may also cause the soldering on the PCB. The position of the electronic components is shifted, which leads to poor PCB placement, and then causes the electronic water pump to work abnormally
