Description
Technical Field
The utility model relates to an electromagnetic relay, especially a adopt flexible movable reed's magnetic latching electromagnetic relay.
Background
An electromagnetic relay is an electronic control device which uses smaller current and lower voltage to control larger current and higher voltage, is usually applied to an automatic control circuit, and plays the roles of automatic regulation, safety protection, circuit conversion and the like in the circuit. The electromagnetic relay is divided into a normally open relay and a normally closed relay according to the state of the coil when the coil is not electrified, and the normally closed relay keeps the attraction between the armature and the coil through magnetic force by arranging the permanent magnet on the armature, so that the closing between the moving contact and the fixed contact is ensured. However, the existing magnetic latching electromagnetic relay has a complex structure and high production difficulty, and is not easy to realize automatic production.
Disclosure of Invention
In view of this, the utility model aims at providing an easy assembling realizes the magnetic latching electromagnetic relay of the flexible movable reed that adopts of automatic assembly easily.
In order to realize the purpose, the utility model adopts a magnetic latching electromagnetic relay adopting a flexible movable spring, which comprises a base, a shell covered outside the base, and a coil, a yoke, an armature, a movable contact, static contacts and a pushing frame which are arranged on the base, wherein the coil is transversely arranged on the base, the two static contacts are respectively arranged at two sides of the movable contact, the front end and the rear end of the coil are both provided with the yoke, the armature is arranged above the coil and is connected with the two yokes, the armature is provided with a permanent magnet, the armature is arranged in the pushing frame, the pushing frame is connected with the base and transversely moves, the movable contact comprises a movable pin and a movable spring, the movable pin is arranged on one side of the base, the static contact is arranged on the other side of the base, the movable spring is connected to the movable pin, the movable spring transversely extends to the static contact to a position between the two static contacts, a contact clamp is formed at the front end of the pushing frame, and the contact clamps are arranged on two sides of the movable spring.
The utility model discloses further set up as the inboard of contact clamp forms the cylinder towards the movable contact spring.
The utility model discloses further set up to movable contact spring is moving and is participating in one side and form one section portion of bending, forms a fore-and-aft line of bending on one side of the static contact.
The utility model has the advantages that the pushing frame is clamped on the two sides of the movable spring leaf through the contact clip, the back and forth movement of the movable spring leaf can be accurately controlled, and the assembly is convenient; the contact surface with the movable spring is a cylindrical surface, so that friction can be reduced, and abrasion is reduced; the bending part increases the flexibility of the movable spring plate, and the mechanical life is prolonged; the movable contact spring can be bent along the bending line, so that the connection stability with the static contact is ensured.
