The invention discloses a self-locking device for a contactor, which comprises a shell body which is fixed on a bottom board, the bottom board, a support post, a bracket, a rotating shaft B, a connecting rod, an electromagnetic valve, a tension spring, a spring, a clamping board, a rotating shaft A, a rotating shaft C and a rotating shaft D which are all in the shell body. The support post is fixed on the bottom board and the bracket, and the rotating shaft A and the rotating shaft D are fixed on the support post; one hole of the clamping board is hinged with the rotating shaft A, one hole ishinged with the rotating shaft C and another one hole is hinged with the connecting rod; the other end of the connecting rod is hinged with an armature of the electromagnetic valve; the tension spring is hung on the rotating shaft C and the rotating shaft D; the rotating shaft B passes through the bottom board, one end of the spring props the inner wall of the bracket and the other end props a cascaded surface of the rotating shaft B; and a handle is hinged with the rotating shaft C. The self-locking device for a contactor has simple structure and can ensure that the main circuit of the contactor is connected when electromagnetic coils are switched off, thereby saving electrical energy and simultaneously being capable of realizing manual unlocking without electricity.
Description
Technical field: [0001] The invention relates to a self-locking device, in particular to a self-locking device for a contactor, which belongs to low-voltage electrical components. Background technique: [0002] The connection of the main circuit of the contactor is realized by energizing the electromagnetic coil to make the iron core and the armature attract. If the main circuit of the contactor is to be kept on all the time, the electromagnetic coil needs to be energized all the time, which wastes a lot of electric energy. Invention content: [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a self-locking device for a contactor. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a self-locking device for a contactor, including a housing and a base plate, the housing is fixed on the base plate, and also includes a pillar, a bracket, a rotating shaft B, a connecting r...
