Abstract
The invention relates to a self-locking relay. The self-locking relay comprises a housing (1), a left electromagnet (2), a right electromagnet (3), a left movable contact (4), a right movable contact (5), a left static contact (6), a right static contact (7), a spring leaf (8), a left lower wiring terminal (9), a left upper wiring terminal (10), a right lower wiring terminal (11), a right upper wiring terminal (12), a lower controlled terminal (13), a left upper controlled terminal (14) and a right upper controlled terminal (15). The left electromagnet (2), the right electromagnet (3), the left movable contact (4), the right movable contact (5), the left static contact (6), the right static contact (7) and the spring leaf (8) are mounted inside the housing (1).
Description
Technical field:
The present invention relates to a kind of self-latching relay, belong to control field.
Background technology:
Currently, in the controlling, if relay to keep, it is necessary to power supply maintains, so maintaining relay operation to need more electric energy.
Summary of the invention:
The present invention relates to a kind of self-latching relay, also can keep the purpose of its duty in power-down conditions realizing relay.
For realizing above-mentioned purpose, the present invention adopts the following technical scheme that
A kind of self-latching relay, comprises:
Shell (1), left electric magnet (2), right electric magnet (3), left moving contact (4), right moving contact (5), left static contact (6), right static contact (7), spring leaf (8), lower-left binding post (9), upper left binding post (10), bottom right binding post (11), upper right binding post (12), under controlled terminal (13), the controlled terminal in upper left (14), the controlled terminal of upper right (15)；As shown in Figure 1.
nullBelow in conjunction with accompanying drawing，Technical construction and the method for the present invention are described: left electric magnet (2)、Right electric magnet (3)、Left moving contact (4)、Right moving contact (5)、Left static contact (6)、Right static contact (7)、Spring leaf (8) is respectively arranged in the inside of shell (1)，Two binding post lower-lefts binding post (9) of left electric magnet (2) and upper left binding post (10) provide electric energy for left electric magnet (2)，Two binding post bottom rights binding post (11) of right electric magnet (3) and upper right binding post (12) provide electric energy for right electric magnet (3)，Left moving contact (4) and right moving contact (5) are a magnet piece with permanent magnetism respectively，Top is silver contact，Left moving contact (4) and right moving contact (5) are separately mounted to spring leaf (8)，Contact is left static contact (6) by left moving contact (4)，Left static contact (6) is connected with the controlled terminal in upper left (14)，Contact is right static contact (7) by right moving contact (5),Right static contact (7) is connected with the controlled terminal of upper right (15)，Spring leaf (8) with under controlled terminal (13) be connected，Before not working，Because left moving contact (4) and right moving contact (5) are permanent magnet，Therefore，Its state then must have one end to be inhaled Guan Bi by left electric magnet (2) or right electric magnet (3)，When needs Reverse Turning Control，Have only on the corresponding electric magnet of left electric magnet (2) and right electric magnet (3) plus inverse current，After completing operation，Then relay need not power up again，Then it is kept closed.
Beneficial effects of the present invention: simple in construction, energy-conservation, reliable operation.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention:
In order to make technical scheme clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail, instantiation described herein, only in order to explain the present invention, is not limited to the present invention.
