The old car used Plug-in installation. Because of the shaking brought by vehical running,the relay often fall off from the bracket , which leads to signal lost.
After analysing and evaluating on the spot, we fully reuse the old relay.
|We design one more PCB board,and weld the relay on it. The old relay body and protection circuit are retained. Also we do not change the original mounting position.|
Throughly solve the relay falling-off situation. And this mode of relay installation obtain a good expansibility.
