Description

push rod relay

technical field

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

Background technique

As the basic control components of electrical systems, relays have been widely used in electromechanical equipment. Existing relays have various structures, including push rod relays.

The working principle of the push rod relay is to generate electromagnetic suction after the coil is energized to attract the armature, so that the armature rotates, which pushes the push rod, which in turn pushes the push rod against the moving reed to make the moving reed contact with the static reed. To realize the closing of the contact, on the contrary, to realize the opening of the contact, the coil current can be reduced to a certain value or the power can be cut off. The current pusher relays generally have the following problems:

The push rod is set between the armature and the moving reed. No matter in the process of assembly or use, the joints between the three are prone to generate more dander due to friction, and the dander will fall to the bottom of the push rod. The card slot will cause the jam phenomenon, which will affect the service life of the relay. Especially in the process of assembling, the generation of dander is more obvious, because the protrusion provided at the front end of the push rod for abutting against the moving reed is thin and usually has burrs, so it is easy to directly generate a large amount of the moving reed during assembly. Scratch to a certain extent, resulting in dander and falling into the relay, resulting in the need to use a blower to blow the dander clean during the assembly process, which seriously affects the production efficiency and increases the labor intensity of workers.

During this process, if a small amount of dander is generated, the dirt trap 8 can accommodate a certain amount of dander, so it is no longer necessary to use the hair dryer frequently. The product will be blown, or the blowing force and time of the hair dryer can be greatly reduced, so the production efficiency can be improved to a certain extent during the assembly process, and the labor intensity of workers can be reduced. The dander generated between them falls down into the card slot 7 and can also further fall into the dirt collecting slot 8 at the bottom of the card slot 7. This is because the rotating shaft 2c and the card slot 7 are in clearance fit. 2c often rotates in the card slot 7 (the working frequency of the relay is very high), which is very easy to squeeze the dander from the card slot 7 into the filth slot 8 for storage, thereby reducing the movement of the rotating shaft 2c. Influence, reduce the risk of sticking, in order to achieve the purpose of improving the service life of the push rod relay.
