Fig. 2. course of work schematic diagram (off-state).
Fig. 3. course of work schematic diagram (on-state).
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Housing (5) is closed up by the forward and backward two halves shell of identical band seam to be made, and main half shell is divided into upper and lower two chambeies again, and sash is arranged on the internal chamber wall, on bottom surface and the side pin bores is arranged.
On the two symmetrical walls of skeleton (2) endoporus v-depression is arranged.
Armature (20) is the middle strip that a pair of protrusion bolster is arranged, and an end has an opening.
Armature (20) is put into skeleton (2) endoporus that is wound with coil (3), protrusion bolster on it is cooperated with v-depression, in the middle of installing, skeleton (2) upper/lower terminal is embedded with the yoke (1) of Nd-Fe-B magnet steel (4), plug is placed in the sash of housing (5) epicoele, and between yoke (1) and housing (5), be embedded with magnetic screen (6), constitute bridge-type magnetic padlock mechanism, mainly prevent in braiding copper wire (8) because of the influence of the ac magnetic field of electric current generation greatly to driving mechanism.
Movable spring plate (17) is
Shape, riveted and fixed moving contact (12) on the small end lower surface is held the fixing end that weaves copper wire (8) of upper surface spot welding greatly.
Arc moving contact (15) is decided in (11) the one end points solid weldings of arc reed, and end is riveted on the movable spring plate (17) in addition, forms in the middle of riveted joint place
The shape through hole, make line-spacing between the dynamic and static contact of arc (15), (14) less than dynamic and static contact (12), (13), and in through hole, insert pivot pin (10), its two ends are weldingly fixed on the support of moving contact pin (7), and the also spot welding of holding in addition of braiding copper wire (8) is fixed on the upper surface of moving contact pin (7).
One side riveted joint fixed contact (13) of the upper surface of fixed contact pin (16), another side point welding arc fixed contact (14), moving contact pin (7), fixed contact pin (16) all are fixed on the fixed head (9) with rivet, are fixed in housing (5) cavity of resorption, constitute the contact and switch the output integral component.
Push pedal (18) is made by insulation board rectangular through-hole, and the upper end is the thin plate of T shape.
The upper end of push pedal (18) is with spring (19), and be connected with the opening of armature (20) one ends, the lower end utilizes the rectangular through-hole on it to be enclosed within on the top of movable contact plate (17) small end, embeds in the sash and breach of housing (5), is connected in aggregates with movable spring plate (17) armature (20).
Balanced reed (21) is fixed on push pedal (18) top, in the sash of housing (5) inwall, is symmetrical in the active force of excess of stroke spring (19), keeps the consistency of the upper and lower action of push pedal (18).
During use; as shown in Figure 2; give coil (3) input a positive pulse; the left side that then is inserted in the armature (20) in the coil rack (2) produces the S utmost point; the right side produces the N utmost point; just the polarity with skeleton (2) two ends yokes (1) is identical and opposite; armature (20) moves as shown in Figure 3 rapidly; the left side moves up; the right side moves down; connected push pedal simultaneously (18) moves down under the effect of spring (19); and drive connected movable spring plate (17) action downwards; arc moving contact (15) on arc fixed contact (14) and the arc reed (11) is at first closed; connect; big electric current is at first passed through and (this arc contact employing alloy material making of generation moment spark at this; be difficult for being melted and scaling loss); voltage between this moment fixed contact pin (16) and moving contact pin (7) descends greatly; moving contact (12) and fixed contact (13) can be connected like a cork; spark greatly reduces during contact; protected moving effectively; fixed contact (12); (13), damage and melting welding phenomenon have been significantly reduced when connecting to contact surface.Simultaneously because of keeping in touch resistance stabilization, can guarantee that again big electric current safety passes through.
When needing to disconnect, as long as to negative pulse of coil (3) input, make the left side of armature (20) produce the N utmost point, the right side produces the S utmost point, then move rapidly downwards in the left side of armature (20), the right side is upper right moves, drive push pedal (18), movable spring plate (17) is upwards action rapidly, at this moment at first be, fixed contact (12), (13) steadily safety disconnects, then a pair of arc extinguishing is moving moment, fixed contact (15), (14) also disconnect, this moment is big because of load current, may produce big electric arc between the arcing contact, but can be by not bonding, avoided moving effectively, fixed contact (12), (13) damage that surperficial arcing causes, after each pulse, the state after this relay keeps moving always, no longer power consumption.So cycling is no longer described in detail.
The utility model is compared with prior art: also comprise the magnetic that is fixed on the skeleton with magnet steel in the driving mechanism The bridge-type magnetic padlock mechanism that yoke forms, therefore not installing any self-locking, bistable circuit additional just has the magnetic padlock function, Not power consumption when static. Because arc reed and the stationary contact pin at movable spring plate in contact change-over output installed additional The dynamic and static contact of a pair of arc extinguishing, and by line-spacing apart from guaranteeing always make-before-break of a pair of arcing contact, and a pair of Main contacts closes after but being earlier disconnected, can pass through big electric current, and arc extinguishing. Thereby protection active, stationary contact are not Damage, melting welding. Volume is little only to be 32 * 18 * 27mm3, but can bear surge, the short circuit current of 100 peaces. Push pedal end cover has excess of stroke spring, and movable spring plate and armature are linked into an integrated entity, and spring can guarantee dynamic and static contact Contact is good, reliable in action, working stability.
