Push rod type relay

Abstract

The invention discloses a push rod type relay, which relates to the technical field of relays and comprises a base, a magnetic circuit portion arranged on the base, a contact portion and a push rod, wherein the magnetic circuit portion comprises a coil and an armature hinged to the base, the upper end of the armature is located above the coil, the lower end of the armature is located on the rightside of the coil, and the contact portion comprises a movable reed and a static reed which are arranged at intervals from left to right. The left end of the push rod is provided with a left protrudingblock abutting against the armature so that the upper end of the armature can be far away from the coil, the right end of the push rod is provided with a right protruding block making contact with the movable reed, the bottom of the push rod is provided with a rotating shaft, the base is provided with a clamping groove matched with the rotating shaft and enabling the rotating shaft to rotate inside, the front end of the clamping groove is opened to enable the rotating shaft to be assembled and inserted, and a dirt containing groove used for containing soft flocks and impurities is further formed in the bottom of the clamping groove. The influence of soft flocks on the relay assembling and using process can be reduced to a great extent, the production efficiency is improved, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a push rod type relay. Background technique [0002] As the basic control component of the electrical system, the relay has been widely used in electromechanical equipment. Existing relays have various structures, including push rod relays. [0003] The working principle of the push rod relay is to generate electromagnetic attraction after the coil is energized to attract the armature, so that the armature rotates, thereby pushing against the push rod, and then making the push rod push against the moving reed so that the moving reed contacts the static reed and thus To realize the closure of the contact, on the contrary, to realize the disconnection of the contact, the coil current is reduced to a certain value or the power is cut off. The current push rod relays generally have the following problems: [0004] The push rod is set between the armature and the moving reed. No mat...

AI Technical Summary

Problems solved by technology

[0004] The push rod is set between the armature and the moving reed. No matter during the assembly process or the use process, the joints of the three are prone to produce more dander due to friction, and the dross will fall to the bottom of the push rod. In the card slot, it will cause stagnation, which will affect the service life of the relay

Especially during the assembly process, the dross generation is more obvious, because the protrusion provided at the front end of the push rod to resist the moving reed is thin and usually has burrs, so it is easy to directly generate a large amount of friction on the moving reed during assembly. Scratches to a certain extent, resulting in lint and falling into the relay, resulting in the need to use a blower to blow off the lint during the assembly process, seriously affecting production efficiency and increasing the labor intensity of workers
