Description
Technical field
The utility model relates to the electromagnetic relay technical field, and specifically, it is a kind of electromagnetic relay of tool modified model movable contact spring.
Background technology
Relay is the automatic switch element with isolation features, in extensive use and remote control, remote measurement, communication, control automatically, electromechanical integration and the power electronic equipment, is one of most important control element.
Movable contact spring is one of parts important in the relay, in the switch of relay and closure, plays an important role.Traditional movable contact spring is essentially laminated structure, and the lower end is connected with pin, promote by push jack, and then the switching of the fixed contact of the moving contact of realization movable contact spring and static contact spring piece.But this movable contact spring makes that scurrying and coming off appears in push jack in the course of the work easily, thereby influences the operate as normal of relay.
Therefore, prior art awaits improving and improving.
The utility model content
The purpose of the utility model is the electromagnetic relay that a kind of tool modified model movable contact spring of working stability is provided for the problems referred to above that overcome prior art.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of electromagnetic relay of tool modified model movable contact spring; Comprise shell, pedestal, push jack, magnetic circuit system and contact system, described contact system comprises that the movable contact spring that has moving contact and the static contact spring piece that has fixed contact, this movable contact spring and static contact spring piece are pressed into pedestal; Described push jack connects the catch of movable contact spring, armature and skeleton upper end; Be respectively equipped with boss on the inwall of the middle process hole both lateral sides of described push jack, the groove stationary fit that the side top of described boss and armature is provided with also fits together; Described magnetic circuit system comprises skeleton, coil, yoke, armature; Skeletal fixation is on pedestal, and it is suitable and be solidified as a whole with the skeleton that is provided with groove to insert yoke on the yoke groove of pedestal, and coil is on skeleton; Near the skeleton installed inside armature is arranged, armature inserts the armature groove of pedestal; The extension sheet that stretches out of level to the left that described movable contact spring top is provided with, this movable contact spring passes the left end that push jack is connected in push jack.
Compared with prior art; The beneficial effect of the utility model is: owing to adopt said structure, promptly the top of movable contact spring is provided with an extension sheet, and this extension sheet can be used as the upper limit bit slice of push jack action; Utilize the elasticity of movable contact spring self simultaneously; Can produce certain reaction force to push jack, make push jack in course of action, can not produce to scurry and phenomenon such as come off, thereby guarantee the operate as normal of relay.The utility model is simple in structure, design is ingenious, has market potential widely.
