The design of over travel of automobile relay and its automatic control

Fanju Zeng


with the development of the automobile industry, more and more general electrical parts are used in automobiles, and the quality of platform and standardized electrical products is also paid more and more attention. Relay plays an important role in auto regulation, safety protection and conversion circuit, so it is widely used in the whole vehicle.
Over travel is one of the important parameters of automobile relay, and its consistency affects the life of relay and other main performance. In traditional manual assembly production or semi-automatic assembly line, due to the inherent errors in parts and assembly, a large number of manual adjustment relays are often needed to over travel.
