Industrial control relay with multifunctional push rod and assembling method for industrial control relay

Abstract

The invention discloses an industrial control relay with a multifunctional push rod and an assembling method for the industrial control relay. The relay comprises a magnetic path system, a contact system, the push rod, a shell and a base, wherein the shell is connected with the base; the magnetic path system, the contact system and the push rod are installed in a cavity which is formed by the shell and the base in a surrounding manner; the push rod is connected between the magnetic path system and the contact system in a horizontal direction; the push rod comprises a main rod part in a movement direction and a baffle wall which adopts a vertical surface structure and is used for isolating strong current and weak current; one end, corresponding to one edge of the baffle wall, of the main rod part is matched with an armature of the magnetic path system while the other end, corresponding to the other edge of the baffle wall, of the main rod part is matched with a movable spring of the contact system; and the upper and lower parts of the main rod part are matched with the shell and the base in a limiting manner. By virtue of the industrial control relay, automatic assembling of the push rod can be realized to improve the assembling efficiency of the industrial control relay and eliminate jumping of the push rod in operation, thereby improving stability of electrical parameters.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to an industrial control relay with a multifunctional push rod and an assembly method thereof, which can realize automatic assembly of the push rod and prevent movement during the movement of the push rod. Background technique [0002] At present, the push rods of industrial control relays are all manually assembled. This is mainly because the base does not have a support structure for the push rod. The push rod is supported by the magnetic circuit system and the contact system. The front end of the push rod is inserted into the moving reed. The moving reed is used to support it, the rear end of the push rod is provided with a bracket, and the armature of the magnetic circuit system fits in the bracket, which is equivalent to the armature of the magnetic circuit system to lift the rear end of the push rod, so that the push rod It is equivalent to hanging between the magnetic circuit ...

Problems solved by technology

[0002] At present, the push rods of industrial control relays are all manually assembled. This is mainly because the base does not have a support structure for the push rod. The push rod is supported by the magnetic circuit system and the contact system. The front end of the push rod is inserted into the moving reed. The moving reed is used to support it, the rear end of the push rod is provided with a bracket, and the armature of the magnetic circuit system fits in the bracket, which is equivalent to the armature of the magnetic circuit system to lift the rear end of the push rod, so that the push rod It is equivalent to hanging between the magnetic circuit system and the contact system. When assembling, firstly insert the front end of the push rod into the moving reed, and then move the armature of the magnetic circuit system to the push rod along the length direction of the base to make the armature The protruding head snaps into the bracket of the push rod. Since the push rod is not supported by the base, the automatic assembly of the rear end cannot be realized, resulting in low assembly efficiency and quality of the industrial control relay, which cannot meet the production needs of the relay. In addition, the push rod and The infinite position structure design between other parts, the movement of the push rod is obvious during the operation, resulting in the disadvantages of repeated electrical parameters and poor stability, which makes the quality of the relay have quality risks
