Problems solved by technology
[0002] During the on-off process of the relay, an arc discharge phenomenon will occur between the dynamic and static contacts, and high temperature will be generated around the contacts, so that the dust, oil and other substances attached to the contact surface will be carbonized and attached to the contact surface, resulting in the electrical performance of the contact. However, at present, only when the electrical performance of the contact drops to a certain extent, the surface of the contact is cleaned manually, which is cumbersome to operate
[0003] At the same time, the contacts of the relay need the electromagnet to be continuously energized during the working process, which wastes electric energy, generates a lot of heat and reduces reliability

Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.
[0032] Such as Figure 1 to Figure 11 As shown, a contact self-cleaning and self-locking relay described in this embodiment includes a base 1 and an outer cover 2. A convex ring platform 11 is protruded from the middle of the base 1, and the opening end of the outer cover 2 is fixed on on the base 1, and form an accommodating space with the base 1;
[0033] It also includes an upper end cover 3, a rotating frame 4, an electromagnet 5, two static contacts 6, a one-way transmission mechanism 7, an energy storage drive mechanism 8, a clutch transmission mechanism 9, and a ring gear 10 arranged in the accommodation space. and two cleaning discs 20;
[0034] The upper end cover 3 is fixed on the top of the convex ring platform 11, and a rotating driving track 3...

The invention discloses a contact self-cleaning and self-locking relay, which includes a base, an outer cover, an upper end cover, a rotating frame, an electromagnet, two static contacts, a one-way transmission mechanism, an energy storage drive mechanism, a clutch type transmission mechanism, Ring gear and two cleaning discs; a rotating drive track is formed between the upper end cover and the base, a first extension spring is provided between the rotating frame and the base, and a first bayonet is provided on the rotating frame, and the first bayonet is movably embedded in the rotating driving track Inside; the floating connection of the rotating frame has a moving contact, and the rotating frame is equipped with an iron block; the one-way transmission mechanism is used to transfer the kinetic energy of the rotating frame to the energy storage drive mechanism; the energy storage drive mechanism is used to store the kinetic energy of the rotating frame and drive the clutch The transmission mechanism drives the ring gear to rotate; the cleaning disc is connected to the ring gear; the invention does not need electromagnets to be continuously energized, which saves electric energy, avoids generating a large amount of heat, and has higher reliability; realizes regular automatic grinding and cleaning of the contacts, ensuring contact points Excellent electrical performance without manual follow-up cleaning.
Description
technical field [0001] The invention relates to the technical field of relays, in particular to a contact self-cleaning and self-locking relay. Background technique [0002] During the on-off process of the relay, an arc discharge phenomenon will occur between the dynamic and static contacts, and high temperature will be generated around the contacts, so that the dust, oil and other substances attached to the contact surface will be carbonized and attached to the contact surface, resulting in the electrical performance of the contact. However, at present, only when the electrical performance of the contact drops to a certain extent, the surface of the contact is cleaned manually, which is cumbersome to operate. [0003] At the same time, the contacts of the relay need the electromagnet to be continuously energized during the working process, which wastes electric energy, generates a lot of heat and reduces reliability. Contents of the invention [0004] The object of the ...
