Abstract
A movable spring plate structure for defining an open or closed state with respect to a fixed contact includes a rigid spring plate contact portion, a soft spring plate warp portion, a soft spring plate force-applying portion and a movable contact. The soft spring plate warp portion is coupled to the rigid spring plate contact portion, and a first deformation gap is formed between the rigid and soft spring plate contact portions. The rigid spring plate contact portion is harder than the soft spring plate warp portion. The soft spring plate force-applying portion is disposed at the soft spring plate warp portion, and the movable contact is disposed at the rigid spring plate contact portion. A force applied to the soft spring plate force-applying portion drives the movable and fixed contacts into a closed state.
Claims9
A movable spring plate structure used in a relay, for defining an open or closed state with respect to a fixed contact, comprising:
- a rigid spring plate contact portion;
- a soft spring plate warp portion, coupled to the rigid spring plate contact portion, and having a first deformation gap formed between the rigid spring plate contact portion and the soft spring plate warp portion, and the rigid spring plate contact portion having a hardness greater than a hardness of the soft spring plate warp portion;
- a soft spring plate force-applying portion, disposed at the soft spring plate warp portion;
- and
- a movable contact, disposed at the rigid spring plate contact portion;
- wherein, when the soft spring plate force-applying portion is driven by a force, and the movable contact and the fixed contact are set into a closed state, the soft spring plate warp portion produces a deformation with respect to the rigid spring plate contact portion.
A relay, comprising:
- at least one movable spring plate structure used in a relay, for defining an open or closed state with respect to a fixed contact, and the movable spring plate structure comprising:
- a rigid spring plate contact portion;
- a soft spring plate warp portion, coupled to the rigid spring plate contact portion, and having a first deformation gap formed between the rigid spring plate contact portion and the soft spring plate warp portion, and the rigid spring plate contact portion having a hardness greater than a hardness of the soft spring plate warp portion;
- a soft spring plate force-applying portion, disposed at the soft spring plate warp portion;
- and
- a movable contact, disposed at the rigid spring plate contact portion;
- wherein, when the soft spring plate force-applying portion is driven by a force, and the movable contact and the fixed contact form a closed state, the soft spring plate warp portion produces a deformation with respect to the rigid spring plate contact portion;
- a base, for installing the movable spring plate structure and the fixed contact;
- at least one electromagnetic structure, disposed at the base, and configured to be corresponsive to the movable spring plate structure;
- and
- at least one pushing assembly, with an end coupled to the soft spring plate force-applying portion;
- and the electromagnetic effect of the least one electromagnetic structure magnetically attracting and driving the movable contact and the fixed contact into an open or closed state after an electrical conduction.
