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 type relay which comprises 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 driving mechanism, a clutch type transmission mechanism, a gear ring and two cleaning discs. A rotary driving track is formed between the upper end cover and the base, a first tension spring is arranged between the rotary frame and the base, the rotary frame is provided with a first bayonet lock, and the first bayonet lock is movably embedded into the rotary driving track; the rotating frame is in floating connection with a movable contact and is provided with an iron block; the one-way transmission mechanism is used for transmitting kinetic energy of the rotating frame to the energy storage driving mechanism; the energy storage driving mechanism is used for storing kinetic energy of the rotating frame and driving the clutch type transmission mechanism to drive the gear ring to rotate; the cleaning disc is in transmission connection with the gear ring; the electromagnet does not need to be electrified continuously, electric energy is saved, a large amount of heat is avoided, and reliability is higher; and regular automatic polishing and cleaning of the contacts are achieved, the electrical performance of the contacts is guaranteed, and manual follow-up cleaning is not needed.
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 ...
