The invention discloses a double-coil relay which comprises a shell and a core located in the shell, wherein the core comprises two coils and a yoke, the yoke is composed of a yoke piece and a pin, the yoke piece and the pin are an integrated piece, and the yoke piece and the pin are integrated through a fine blanking metal plate bending technology. According to the double-coil relay, the yoke piece and the pin of the yoke are the integrated piece, the riveting process and riveting production devices of the yoke piece and the pin are omitted, assembly errors can be reduced, the precision of products is improved, the difficulty for assembling the relay is lowered, the production efficiency is improved, the production cost is lowered, space is won for design of the products, and materials are saved.
Description
technical field [0001] The invention relates to an automotive electronic device, in particular to a two-wire package relay. Background technique [0002] Small relays are a product with mature technology and are widely used in automotive electronic devices. The existing small two-wire package relays used in automotive electronic devices include a housing and a core assembled in the housing. The core includes Two sets of coils and a yoke. The yoke is composed of two parts: a yoke piece and a pin. The yoke piece and the pin are discrete components and are usually connected as a whole by riveting. The yoke in this connection method has the following disadvantages Where: [0003] 1. Due to the small size of the yoke and pins, assembly is relatively difficult and the accuracy is difficult to guarantee; [0004] 2. Due to the need to rivet the yoke iron sheet and the pin, the production process and production equipment are increased, which affects production efficiency and incre...
