The invention discloses a contactor structure. The structure comprises a shell. An electromagnet is mounted at the bottom in the shell. A movable iron core is mounted at the upper part of the electromagnet. A first connecting rod is mounted on the movable iron core. A reset spring is arranged between the top of the first connecting rod and the shell. A cross rod is transversely mounted on the first connecting rod. Movable contacts are symmetrically mounted on two sides of the cross rod. Normally-closed contact binding posts are symmetrically installed on the two sides of the upper portion of the shell. The normally-closed contact binding post is provided with a normally-closed contact in the shell. The normally-closed contact corresponds to the movable contact in position. A normally-opencontact binding post is installed on the lower portion of the shell, a normally-open contact is installed on the portion, in the shell, of the normally-open contact binding post, the normally-open contact corresponds to the movable contact in position, supporting shafts are symmetrically installed between the normally-closed contact binding post and the normally-open contact binding post, the twosupporting shafts are located on the two sides of the movable contact, and first shaft sleeves are symmetrically installed at the two ends. According to the invention, the defects in the prior art canbe overcome, rapid arc extinction between contacts of the contactor is realized, and the contactor performance is improved.
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 107591289 B 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 inve...
