The invention discloses a contactor structure, which comprises a shell, an electromagnet is installed on the inner bottom of the shell, a movable iron core is installed on the upper part of the electromagnet, a first connecting rod is installed on the movable iron core, and the top end of the first connecting rod is connected with the shell. A return spring is installed between them, a cross bar is installed horizontally on the first connecting rod, movable contacts are symmetrically installed on both sides of the cross bar, normally closed contact terminals are symmetrically installed on both sides of the upper part of the shell, and the normally closed contact terminals are on the There is a normally closed contact installed in the shell, and the position of the normally closed contact corresponds to the position of the moving contact. The lower part of the shell is equipped with a normally open contact terminal. The position of the contact corresponds to the position of the moving contact. There are support shafts symmetrically installed between the normally closed contact terminal and the normally open contact terminal. The two support shafts are located on both sides of the movable contact. bushing. The invention can solve the disadvantages of the prior art, realize fast arc suppression between contacts of the contactor, and improve the performance of the contactor.
Description
technical field [0001] The invention relates to an electrical control device, in particular to a contactor structure. Background technique [0002] The contactor is an electrical device used in electric power, power distribution and power consumption occasions. It uses a coil to flow current to generate a magnetic field to close the contacts to control the load. Chinese invention patent CN 107591289B discloses a contactor. The contactor with this structure has a simple structure and cannot quickly eliminate the arc between the contacts, which limits its scope of application. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a contactor structure, which can solve the deficiencies of the prior art, realize rapid arc suppression between contacts of the contactor, and improve the performance of the contactor. [0004] In order to solve the above technical problems, the technical solutions adopted by the present inven...
