Abstract
The utility model relates to a miniature relay, including casing, base, electromagnetic unit, yoke, armature, insulating cover, movable contact spring, fixed contact piece, the yoke is the n-shaped, inserts and establishes on the base, and the electromagnetic unit cover is established at the yoke middle part, and electromagnetic unit sets firmly in the base top via the yoke, the armature card is established on the base, and the one end contact of one end and yoke cooperates, and the other end is counterpointed with the other end of yoke and is cooperated, armature middle part cover is equipped with insulating cover, movable contact spring one end is inserted and is established on the base, and the movable contact spring is contradicted with insulating cover and is cooperated, on fixed contact piece inserts and is equipped with the base, with the movable contact spring cooperation of counterpointing, insulating sheatheeing in is equipped with the boss, and this boss is contradicted with the movable contact spring and is cooperated, movable contact spring no. 1 is served and is equipped with two fixed contacts, fixed contact piece no. 1 serves and is equipped with two fixed contacts corresponding with the movable contact. The utility model discloses compact structure, it is small, have when realizing relay function in can less space, guarantee that the electric property of relay is unchangeable.
Description
Technical field
The utility model relates to a kind of relay, specifically a kind of miniature relay of compact conformation.
Background technology
Electrical equipment is the automatic switch element with isolation features, and being widely used in remote control, remote measurement, communication, automatically control, electromechanical integration and power electronic equipment, is one of most important control element.
Along with electrical equipment is towards miniaturized, integrated hair style, the headspace of electrical equipment inside is more and more less, so the dimensional requirement for relay is more and more higher, existing relay, because of structure and the dual reason of electric property, constrains the further reduction of its volume.
Utility model content
The purpose of this utility model is the deficiency of relay existing on volume overcoming existing structure, provides the miniature relay that a kind of volume is little, performance is good.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of miniature relay, comprise housing, pedestal, electromagnetic unit, yoke, armature, insulating case, movable contact spring, fixed touching plate, described yoke is Jiong word shape, be plugged on pedestal, electromagnetic unit is set in the middle part of yoke, and electromagnetic unit is installed in above pedestal via yoke; Described armature is fastened on pedestal, and one end coordinates with the end thereof contacts of yoke, and the other end coordinates with the other end contraposition of yoke; Insulating case is arranged with in the middle part of described armature; Described movable contact spring one end is plugged on pedestal, and movable contact spring is conflicted with insulating case and coordinated; Described fixed touching plate is inserted with on pedestal, coordinates with movable contact spring contraposition; Described insulating case is provided with boss, and this boss is conflicted with movable contact spring and coordinated; Described movable contact spring one end is provided with two fixed contacts; Described fixed touching plate one end is provided with two fixed contacts corresponding with moving contact.
When the utility model is implemented, utilize yoke to contact with armature and carry out magnetic conduction, and then after electromagnetic unit is energized, armature one end and the adhesive of yoke corresponding end, then, the boss top on the armature of adhesive presses contact, and the fixed point of movable contact spring and fixed touching plate is come in contact.
The utility model compact conformation, volume is little, has while can realizing relay function in less space, ensures that the electric property of relay is constant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after the utility model removes housing and pedestal.
Embodiment
Further understand for convenience of doing this practicality, existing by reference to the accompanying drawings for an embodiment, the utility model is further described.
Embodiment:
