AI Technical Summary
In existing electromagnetic relays, the non-parallelism of the sheet-like connectors on the base and the electromagnetic mechanism results in a small contact area, making it impossible to achieve a stable connection.
Design a connector including a first connecting piece and a second connecting piece. The first connecting piece is fixed on a base, and the second connecting piece is in contact with the structural surface of the connecting piece. By setting an intermediate connecting part, the first connecting piece and the second connecting piece are made perpendicular to each other, increasing the contact area, and resistance welding is used to connect them.
By increasing the contact area, the stability of the connection is improved, avoiding the risks of incomplete soldering, deformation and breakage, and the welding time is short and the connection strength is high.
