Abstract: A connecting structure between lead-out pins (71) of auxiliary stationary contacts and a yoke plate (5) of a DC relay, includes a yoke plate and a plurality of auxiliary stationary contact lead-out terminal assemblies (7) mounted on the yoke plate; each auxiliary stationary contact lead-out terminal assembly includes a lead-out pins (71), a glass material body (72) and a kovar alloy part (73); the lead-out terminal, the glass material body and the kovar alloy part are connected into a whole by sintering, and the lead-out terminal and the kovar alloy part are insulated from each other by glass material; the auxiliary stationary contact lead-out terminal assembly is welded and fixed to the yoke plate through the kovar alloy part. The present disclosure can not only reduce the volume of the product (shrink the space in the height direction), and contribute to the miniaturization of the product, but also has the characteristics of simple structure and low process difficulty.
