Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
As Fig. 1, this electromagnetic type Self-disconnecting plug comprises housing 1, and the metal being assemblied in described housing 1 front and back end respectively inserts bar, outer tie-in line 3; Described metal cutting comprises live wire cutting 21, zero line cutting 22; Described live wire cutting 21 is electrically connected with described outer tie-in line 3 by stuck-module 11, sliding block 12, described stuck-module 11 is fixedly wound with main coil 13, described main coil 13 is connected with the metal clips 14 being fixed on described housing 1 inside, and described metal clips 14 compresses with the metal connection plate 15 of described sliding block end and is connected; Described sliding block 12 can be assembled by slide anteroposterior by the slip ring 16 being fixed on described housing 1 inside, the front end of described sliding block 12 is fixedly wound with secondary coil 17, described metal connection plate 15 is connected with the front end of described secondary coil 17, and the rear end of described secondary coil 17 is connected with described outer tie-in line 3; The rearward end of described sliding block 12 is connected with the main spring 18 being fixed on housing 1 inside.
This electromagnetic type Self-disconnecting plug can be used for plug on alternative traditional appliance plug or mobile socket, on this plug, the live wire cutting 21 of metal insertion bar is connected with outer tie-in line 3 by described stuck-module 11, sliding block 12, and described outer tie-in line 3 is connected with electrical appliance or mobile socket.When this electromagnetic type Self-disconnecting plug normally works as shown in Figure 1, now described metal clips 14 compresses with the metal connection plate 15 of described sliding block end and is connected, this plug electric current is switched on, and the electric current in electrical network is formed path entered electrical appliance by live wire cutting 21, main coil 13, metal clips 14, metal connection plate 15, outer tie-in line 3.When electrical appliance is started working, the main coil 13 that described stuck-module is wound around and secondary coil 17 all have electric current to pass through, and can produce magnetic action power therebetween, and the winding direction specifically due to described main coil 13, secondary coil 17 is contrary.Such main coil 13, secondary coil 17 produce repulsion, make described sliding block 12 away from described stuck-module 11, thus described metal clips 14 is departed from mutually with metal connection plate 15, form state as shown in Figure 2, thus make whole line interruption.
In this electromagnetic type Self-disconnecting plug, owing to being same electric current in described main coil 13, secondary coil 17, the words that the winding direction of main coil 13, secondary coil 17 is contrary, be no matter alternating current or direct current main coil 13, secondary coil 17 stressed constant, this plug alternating current or direct current can use like this.This electromagnetic type Self-disconnecting plug construction is simply easy to use; by plug just can when electrical appliance electric current is excessive auto-breaking; do not need to be designed with overcurrent protection structure in electrical appliance; enormously simplify the syndeton of electrical equipment; this power-off protection structure can be used on multiple electrical appliance simultaneously; this plug relative to electrical appliance can large batch of cost of manufacture lower, thus the production cost of electrical appliance can be reduced on the whole, be convenient to the quick manufacture of electrical appliance simultaneously.
As depicted in figs. 1 and 2, described housing 1 is separated into two independently cavitys by middle coverboard 19, and described stuck-module 11, sliding block 12 are assemblied in same cavity.Contacting of zero line and live wire can be completely cut off so thoroughly, thus more safe when this plug is used.
Memory metal is marmem again, has when different temperature, the characteristic of refresh memory shape.As depicted in figs. 1 and 2, described zero line cutting 22 is connected with the modified strip 101 being assemblied in described housing 1 inside, described modified strip 101 uses memory metal material to be made, and the zero line of described outer tie-in line 3 is electrical connected with the zero line intercell connector 102 being assemblied in described housing 1 inside; Specifically, as shown in Figure 1, described modified strip 101, when remembering below deformation temperature, is adjacent to described zero line intercell connector 102 and is electrical connected, the circuit ON that zero line is corresponding; As shown in Figure 2, when in this plug, electric current is excessive, modified strip 101 heating temp uprises, and when the temperature of described modified strip 101 arrives more than memory deformation temperature, is separated with described zero line intercell connector 102.Described modified strip 101 is same with zero line intercell connector 102 can produce power-off effect when current loading is excessive, and this structure and the cut-off structure that live wire is connected are with the use of making the level of security of this plug higher.Simultaneously when described modified strip 101 is separated with zero line intercell connector 102, modified strip 101 is in higher temperature state, modified strip 101 could become original form after needing cooling again, modified strip 101 is contacted again with described zero line intercell connector 102, if when described like this metal clips 14 is communicated with again with metal connection plate 15, zero line place circuit still can be in off state, could entirety reclose until modified strip 101 cools rear circuit, this connected mode makes this plug have an interval time by force after a loss of power, make electrical equipment use procedure safer.Simultaneously around electrical appliance when breaking out of fire or other high-temperature situation, this plug can auto-breaking, the safety of protection electrical appliance.
As depicted in figs. 1 and 2, described sliding block 12 is connected with card article 104 by auxiliary spring 103, the inner side of described slip ring 16 is processed with spacing hole, adjustment hole, the end of described card article 104 is circular shape, described adjustment hole runs through described slip ring, is equipped with the button 105 stretching out described housing side in described adjustment hole.Described spacing hole, adjustment hole are respectively to should the opening and closing state of plug, and when the end of card article 104 is carried out spacing by described spacing hole, as shown in Figure 1, described metal clips 14 is communicated with metal connection plate 15, and live wire is in connected state.When described current overload, described sliding block 12 promotes together with described genus terminal block 15 greatly by the stressed change of described secondary coil 17, makes card article 104 depart from spacing hole and arrives described adjustment hole position, as shown in Figure 2.Now described metal clips 14 departs from metal connection plate 15, live wire disconnects, current interruptions, described main spring 18 is compressed, when described card article 104 presses by described button 105 to the inside, described sliding block 12 can be pushed up meeting front again by main spring 18, makes card article 104 reenter described spacing hole position, live wire circuit is resetted.The use of this structure makes this plug can Reusability.
