Description
Technical field
The utility model relates to electronic control device technical field, specifically refers to a kind of electromagnetic relay.
Background technology
During electromagnetic relay work, as long as add certain voltage at coil two ends, will flow through certain electric current in coil, thus produce galvanomagnetic effect, armature promotes movable contact spring after being attracted by coil, until movable contact spring contacts with static contact spring piece, realizes the connection to circuit.When after coil blackout, galvanomagnetic effect also disappears thereupon, and armature returns to original position, and movable contact spring is separated with static contact spring piece, realizes the cut-out to circuit.When electromagnetic relay is used in circuit, need to carry out break-make frequently, but current electromagnetic relay is when armature promotion movable contact spring contacts with static contact spring piece, the contact point of movable contact spring and armature changes, in the course of time the distortion causing movable contact spring is easy to, thus the reliability that movable contact spring contacts with static contact spring piece can be affected, reduce the useful life of electromagnetic relay.
Utility model content
The technical problems to be solved in the utility model is, there is provided a kind of when armature promotion movable contact spring contacts with static contact spring piece, the contact point of movable contact spring and armature can be avoided to change, thus the reliability that movable contact spring contacts with static contact spring piece can be ensured and contribute to improving the electromagnetic relay in useful life.
For solving the problems of the technologies described above, the utility model provides a kind of electromagnetic relay of following structure: the upper cover comprise pedestal, being fastened and connected with pedestal, be fixed on movable contact spring on pedestal with static contact spring piece, be fixed on pedestal and be wrapped the skeleton of coil, the yoke be fixedly connected with skeleton one end and the armature with yoke one end snapping and for touching movable contact spring, one end of armature and the other end of skeleton are oppositely arranged, the other end of armature is resisted against on movable contact spring, one end that armature and movable contact spring lean and the armature being positioned at movable contact spring side is provided with projection.
Electromagnetic relay of the present utility model, wherein, projection is arc shape, and the position that movable contact spring contacts with armature can be made not change.
Electromagnetic relay of the present utility model, wherein, one end that armature and movable contact spring lean and armature away from movable contact spring side is provided with depression, depression and projection are oppositely arranged, by the setting of depression, the effect strengthening structural stability can be played, and can material be saved.
Electromagnetic relay of the present utility model, wherein, the bottom of depression is provided with chamfering.
After adopting said structure, compared with prior art, the utility model has the following advantages: by one end of leaning at armature and movable contact spring the armature being positioned at movable contact spring side arranges projection, and projection is arc shape, when armature promotion movable contact spring contacts with static contact spring piece, protruding with between movable contact spring for arcwall face contacts, the position that movable contact spring contacts with armature is not changed, avoid the appearance causing movable contact spring metaboly due to the change of movable contact spring contact position, thus ensure that the reliability that movable contact spring contacts with static contact spring piece, improve the useful life of electromagnetic relay.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-3, in this specific embodiment, electromagnetic relay of the present utility model, comprise pedestal 1, the upper cover 2 be fastened and connected with pedestal 1, be fixed on the movable contact spring 3 on pedestal 1 and static contact spring piece 4, to be fixed on pedestal 1 and to be wrapped the skeleton 6 of coil 5, the yoke 7 be fixedly connected with skeleton 6 one end and the armature 8 with yoke 7 one end snapping and for touching movable contact spring 3, one end of armature 8 and the other end of skeleton 6 are oppositely arranged, the other end of armature 8 is resisted against on movable contact spring 3, one end that armature 8 and movable contact spring 3 lean and the armature 8 being positioned at movable contact spring 3 side is provided with protruding 81.
As the improvement project of the present embodiment, protruding 81 is arc shape, when armature 8 promote movable contact spring 3 contact with static contact spring piece 4 time, protruding 81 with between movable contact spring 3 for arcwall face contacts, the position that movable contact spring 3 contacts with armature 8 is not changed, one end that armature 8 and movable contact spring 3 lean and armature 8 away from movable contact spring 3 side is provided with depression 82, depression 82 is oppositely arranged with protruding 81, the bottom of depression 82 is provided with chamfering, by cave in 82 setting, the effect strengthening structural stability can be played, and can material be saved.
Above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection range that the utility model claims determine.
Claims (4)
1. an electromagnetic relay, comprise pedestal (1), the upper cover (2) be fastened and connected with pedestal (1), be fixed on the movable contact spring (3) on pedestal (1) and static contact spring piece (4), be fixed on pedestal (1) to go up and the skeleton (6) being wrapped coil (5), the yoke (7) be fixedly connected with skeleton (6) one end and the armature (8) with yoke (7) one end snapping and for touching movable contact spring (3), one end of described armature (8) and the other end of skeleton (6) are oppositely arranged, the other end of described armature (8) is resisted against on movable contact spring (3), it is characterized in that: one end that described armature (8) and movable contact spring (3) lean and the armature (8) being positioned at movable contact spring (3) side is provided with projection (81).
