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 basic control components of electrical systems. The existing relays are various in structure, and push rod type relays are also included.

The working principle of the push rod type relay is that electromagnetic attraction force is generated after the coil is electrified to attract the armature, so that the armature rotates to push against the push rod, and then the push rod pushes against the movable reed to enable the movable reed to be in contact with the static reed so as to realize the closing of the contact, otherwise, the coil current is reduced to a certain value or the current is cut off to realize the opening of the contact. The following problems are common in the current push rod relay:

the push rod sets up between armature and movable reed, no matter in the equipment in-process or in-process of using, the junction of three all produces more filings because of the friction easily, and the filings can drop the draw-in groove that push rod bottom was located in and then cause the jamming phenomenon, influences the life of relay. Especially, the generation of the fuzzes in the assembly process is more obvious, because the bulges arranged at the front end of the push rod and used for propping against the movable reed are thinner and are usually provided with burrs, the movable reed is easy to be scraped to a greater extent directly during the assembly, so that the fuzzes are generated and fall into the relay, and the fuzzes are required to be blown clean by a blower in the assembly process, so that 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 so as to greatly reduce the influence of fuzziness on the assembly and the use process of the relay, improve the production efficiency and prolong the service life of products.

In order to solve the technical problems, the invention adopts the following technical scheme: the utility model provides a push rod relay, includes the base, sets up at the left magnetic circuit portion of base, sets up the contact site on the base right side and sets up the push rod between magnetic circuit portion and contact site, magnetic circuit portion includes coil and articulates armature on the base, the upper end of armature is located the top of coil, the lower extreme is located the right side of coil, the contact site includes movable reed and the quiet reed that from left to right interval set up, thereby the left end of push rod is equipped with the left lug that supports and lean on armature and can make armature upper end keep away from the coil, the right-hand member of push rod is equipped with the right lug that contacts with movable reed, the armature can promote the push rod swing, thereby can make right lug push against movable reed and make movable reed contact quiet reed, the bottom of push rod is provided with the pivot, set up on the base and match and can supply the pivot at its inside pivoted draw-in groove, the front end of draw-in groove is opened for the pivot equipment to insert, the tank bottom of draw-in groove has still offered and has been used for holding the dirt impurity.

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

More preferably, the bottom surface of the scale holding tank is an arc-shaped surface.
