Abstract

The invention provides a relay. In the relay, a motor is in transmission connection with a rotating shaft by a gear; a pull block is arranged on a final gear and is connected with one end of a spring sheet, and the other end of the spring sheet is connected on a latch group; one end of a prepressing elastic part is fixed on the wall of a bottom shell, and the other end of the prepressing elastic part is pressed on the latch group; movable contacts are also arranged on the latch group; static contacts are arranged at one end, which corresponds to the movable contacts, of a static contact sheet; one end of a movable contact sheet is connected on the latch group; and a contact pin and a binding post are arranged on a control circuit board. The relay has high pressure of the contacts, reliable contact of products, low temperature rise of the contacts, stable performance, a simple structure, high impact and vibration resistance and large switching power of the contacts.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a relay. Background technique [0002] A self-holding relay is a relay that uses low voltage to control high voltage. The self-holding relay provided by the prior art has low contact pressure, unreliable product contact, high contact temperature, unstable performance, poor shock and vibration resistance, and low contact switching power. Contents of the invention [0003] The invention provides a relay with high contact pressure, reliable contact, low contact temperature rise and stable performance. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] A relay, which includes: a bottom case 115, on which a motor 114 for driving an action, a control circuit board 113, a shrapnel 126, a pre-pressed elastic part, a bow set, a gear set, a pulling block 127, a second A rotating shaft 124, a second rotat...
