The relay adopts the mechanical transmission function and let the contacts of the relay in normally open or normally closed state at the same time, thereby realizes the fast break of the connected electric appliances under control. And the relay has advantages of decreasing the relay manufacture cost and reducing the electrical energy consumption.
Description
Technical field
The utility model relates to the electric machines control technology field, especially relates to a kind of urgency and stops the formula relay.
Background technology
Relay is mainly used in remote starting or control AC/DC motor, and main circuit and the control circuit of connecting the disjunction operate as normal, relay of the prior art cuts off the power supply rapidly in order to make the controlled electrical equipment that joins with it, general all is the attraction of utilizing the inner hot-wire coil of relay, directly attract armature, thereby make the contact of relay be in Chang Kai or normally off simultaneously, to reach the purpose of output non-transformer output, the relay that this realization is cut off the power supply rapidly has following shortcoming: first, because the resulting pressure in contact is less than the attraction of hot-wire coil, make the contact of relay be in Chang Kai or normally closed state, need powerful coil, thereby the manufacturing expense of relay is just high; The second, owing to adopt the mode of coil electricity, must make relay often keep specified electric current, so the power consumption of relay is more.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, provide a kind of urgency to stop the formula relay, make the contact of relay be in Chang Kai or normally off simultaneously by mechanically operated effect, to reach the purpose of output non-transformer output, this urgency stop the formula relay have cheap, energy-conservation obvious and easy to operate advantage.
Urgency of the present utility model is stopped the formula relay and is mainly comprised housing, screw, knob, revolving part, jacking block, top spring, drive link, goes up fixed contact, moving contact, following fixed contact, spring, moving iron core, hot-wire coil, static iron core and drive link appearance frame.Knob is positioned at the top of relay, fixedly connected with following revolving part by screw, jacking block is positioned at the bottom of revolving part, pass through rotary knob, the driven rotary part can make jacking block move up and down, be that drive link holds frame below jacking block, in holding frame, drive link has the drive link that can move up and down, the middle position of drive link bottom has the top spring, it can guarantee that drive link well contacts with the jacking block realization on top, has fixed contact on two pairs at two side positions below the drive link, moving contact and following fixed contact, wherein, two pairs of moving contacts are installed in respectively on a pair of moving iron core, and moving iron core has antagonistic spring, also be surrounded with coil on moving iron core, the position below corresponding two moving iron cores is equipped with a pair of static iron core.
Urgency of the present utility model is stopped the formula relay owing to adopt mechanically operated effect to make the contact of relay can be in Chang Kai or normally off simultaneously, thereby realize the purpose of outage rapidly, its advantage is the manufacturing expense that has reduced relay, has reduced the consumption of electric energy, and handled easily.

With embodiment urgency of the present utility model is stopped the formula relay with reference to the accompanying drawings and do explanation in further detail.
Fig. 1 is the anxious mechanical structure schematic diagram that stops the formula relay;
Fig. 2 is the anxious electrical schematic diagram of formula relay when initial condition that stop;
Fig. 3 is the anxious electrical schematic diagram of formula relay when the direct current machine forward is worked that stop;
Fig. 4 is the anxious electrical schematic diagram of formula relay when the direct current machine reverse operation that stop;
Fig. 5 is the anxious electrical schematic diagram of formula relay in the anxious stopping time of control direct current machine that stop;
Embodiment
As shown in Figure 1, urgency of the present utility model stop the formula relay mainly comprise housing 29, screw 1, knob 2, revolving part 3, jacking block 4, top spring 5, drive link hold frame 17, drive link 6, two pairs go up fixed contact 7 and 26, the two pairs of moving contacts 8 and 25, the two pairs of following fixed contacts 9 and 24, spring 10, a pair of moving iron core 11 and 23, hot- wire coil 12 and 21, a pair of static iron core 13 and 22.Knob 2 is positioned at the top of relay, fixedly connected with following revolving part 3 by screw 1, jacking block 4 is positioned at the bottom of revolving part 3, by rotary knob 2, driven rotary part 3 can make jacking block 4 move up and down, be that drive link holds frame 17 below jacking block 4, in holding frame 17, drive link has the drive link 6 that can move up and down, the middle position of drive link 6 bottoms has top spring 5, it can guarantee that drive link 6 well contacts with jacking block 4 realizations on top, has fixed contact 7 and 26 on two pairs at two side positions below the drive link 6, the two pairs of moving contacts 8 and the 25 and two pairs of following fixed contacts 9 and 24, wherein, described two pairs of moving contacts 8, the 25th, be installed in a pair of moving iron core 11 respectively, on 23, moving iron core has antagonistic spring 10, and on moving iron core 11 and 23, also be surrounded with coil 12 and 21 respectively, on the position below corresponding two moving iron cores, be separately installed with a static iron core 13 and 22.In the embodiment that this figure illustrated, relay is in and anxious stops state, and at this moment, the two pairs of moving contacts 8 of relay and 25 disconnect with last fixed contact 7 and 26 respectively, under the effect that drive link 6 presses down, are in contact with one another with following fixed contact 9 and 24 respectively.
As shown in Figure 2, when direct current machine 16 does not have the initial condition of energising, the two pairs of moving contacts 8,25 that suddenly stop the formula relay respectively and two pairs go up fixed contacts 7,26 and be in contact with one another, at this moment, two pairs of contacts of relay are in closure state simultaneously, and therefore, direct current machine 16 does not have electric current to pass through.
As shown in Figure 3, when direct current machine 16 is worked at forward, hot-wire coil conduction makes the moving iron core 23 above 22 pairs of the static iron cores produce the suction-combining forces, thereby moving downward to break away from, moving contact 25 goes up fixed contact 26, and contact with following fixed contact 24, at this moment, suddenly stop the pair of contact closure of formula relay, another disconnects the contact.
As shown in Figure 4, direct current machine 16 is when reverse operation, hot-wire coil conduction makes the moving iron core 11 above 13 pairs of the static iron cores produce the suction-combining forces, thereby moving downward to break away from, moving contact 8 goes up fixed contact 7, and contact with following fixed contact 9, at this moment, suddenly stop the pair of contact closure of formula relay, another disconnects the contact.
As shown in Figure 5, make the anxious stopping time of relay in control, with knob 2 rotations 45 degree, at this moment, jacking block 4 presses down drive link 6, thereby the two pairs of moving contacts 8 and 25 of relay are in contact with one another respectively with following fixed contact 9 and 24, at this moment, two pairs of contacts of relay are in off-state simultaneously, therefore, direct current machine does not have electric current to pass through, thereby reaches anxious purpose of stopping.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection range of the present utility model.
