Description

Push-rod relay

Technical Field

The invention relates to the technical field of relays, in particular to a push rod type relay.

Background

Relays are commonly used in electromechanical devices as the basic control component of electrical systems. The existing relay has various structures, and the push rod type relay is also included in the existing relay.

The operating principle of the push-rod relay is that electromagnetic attraction is generated after the coil is electrified so as to attract the armature, the armature rotates, the push rod is pushed, the movable contact spring is pushed by the push rod so that the movable contact spring is contacted with the static contact spring to close the contact, otherwise, the coil current is reduced to a certain value or the power is cut off when the contact is disconnected. The following problems generally exist in the existing push rod type relay:

the push rod sets up between armature and movable spring, no matter in the equipment process or in the use, three's linking department all produces more flock because of the friction easily, and the flock can drop in the draw-in groove that the push rod bottom is located and then cause the jamming phenomenon, influences the life of relay. Especially, the production of the burrs in the assembling process is more obvious, because the protrusion arranged at the front end of the push rod and used for abutting against the movable spring is thin and has burrs generally, the movable spring is easily and directly scratched to a large extent during assembling, the burrs are generated and fall into the relay, the burrs are blown clean by using a blower in the assembling process, the production efficiency is seriously influenced, and the labor intensity of workers is increased.

Disclosure of Invention

The invention aims to provide a push rod type relay, which aims to greatly reduce the influence of burrs on the assembly and use process of the relay, improve the production efficiency and prolong the service life of a product.

In order to solve the technical problems, the invention adopts the following technical scheme: a push-rod type relay comprises a base, a magnetic circuit part arranged on the left side of the base, a contact part arranged on the right side of the base and a push rod arranged between the magnetic circuit part and the contact part, wherein the magnetic circuit part comprises a coil and an armature hinged on the base, the upper end of the armature is positioned above the coil, the lower end of the armature is positioned on the right side of the coil, the contact part comprises a movable spring and a static spring which are arranged at intervals from left to right, the left end of the push rod is provided with a left lug which is abutted against the armature so as to enable the upper end of the armature to be far away from the coil, the right end of the push rod is provided with a right lug which is contacted with the movable spring, the armature can push the push rod to swing so as to enable the right lug to push the movable spring to be abutted against the movable spring so as to enable the movable spring to be contacted with the static spring, the bottom of the push rod, the bottom of the clamping groove is also provided with a dirt containing groove for containing flock impurities.

Preferably, the length of the scale containing groove is consistent with that of the clamping groove.
