Description
Technical Field
[0001] The utility model relates to the technical field of relays, in particular to an implantable relay structure for preventing the generation of assembly foreign matters. Background Art
[0002] A relay is an automatic control device whose output will change in a jump when the input reaches a certain value, and is widely used in vehicles. The bottom of the existing relay coil holder is in a fully enclosed state, with materials on all sides. A square hole is opened on one side of the bottom of the coil holder to install the yoke iron into the coil holder: the yoke iron is usually in an L-shaped shape with a bent part. One side of the I-shaped yoke iron passes through the square hole of the coil holder, and the other side leans against the bottom of the coil holder and is attached to the iron core hole of the coil holder to be connected to the iron core. The bent part of the yoke iron leans against the square hole of the coil holder. In this way, the thickness of the yoke iron just fills the square hole of the coil holder, making the bottom of the coil holder in a fully enclosed state, and the potting glue and foreign matters will not leak into the relay. However, for this kind of relay with this structure, there is no separate base component, and the base and the bottom of the coil holder are combined into one. In order to prevent the generation of assembly foreign matters, the bottom of the coil holder is usually designed to be fully enclosed, which results in that the yoke iron can only be installed along the central axis direction of the iron core hole of the coil holder. At the same time, one side of the yoke iron has to pass through the square hole of the coil holder, and plastic chips are easily generated during the perforation process, which will contaminate the relay contacts, resulting in unreliable contact and slow assembly speed. Therefore, the utility model proposes an implantable relay structure for preventing the generation of assembly foreign matters. Summary of the Utility Model
