Abstract
A kind of wiring board technical field of induction switching-off is related to a kind of electric elements, specifically a kind of wiring board.The common wiring board of background technique cannot automatically power off under special occasions, to reduce its convenience.Summary of the invention uses electromagnetic induction principle, to realize automatic circuit break function.The specific technical solution of wiring board is one knife switch of setting on plug, there is the armature with iron core cooperation on knife switch, knife switch is by spring straining on switch housing, knife switch is closed with hand push button when use, coil passes through electric current, so that iron core is generated magnetic field, armature engaged therewith is sucked.Since the suction that iron core generates is greater than the pulling force of spring, so even if release button, push-button reset to original position, knife switch is still within closed state, to guarantee to open a way.When the load on circuit is closed, circuital current becomes 0, and iron core no longer generates magnetic field, and knife switch disconnects circuit under the tensioning function of spring.
Description
Technical field
The utility model relates to a kind of electric elements, specifically a kind of wiring board.
Background technique
Common wiring board has the function of extending circuit.But common wiring board cannot automatically power off under special occasions, from
And reduce its convenience.
Summary of the invention
The utility model technical issues that need to address are to overcome the shortcomings of background technique, provide a kind of structure and simply close
Reason, can be realized the wiring board of induction switching-off.
The wiring board of the utility model mainly uses electromagnetic induction principle, to realize automatic circuit break function.By this reality
When being used for the charging of residential customer electricity consumption vehicle with novel wiring board, can make that user trusts downstairs by electricity consumption vehicle
It is inserted on terminal plate, then presses indoor button again, start to charge.And when other people deliberately pull up the charging of electricity consumption vehicle
Device, it is desirable to the electricity consumption vehicle of himself be inserted into when charging on this terminal plate, due to pulling up the action triggers induction of charger
Power-off, so will not charge at this time.Since in this way, what residential customer can trust is fixed on wiring board in one place, removes from
The trouble of folding and unfolding wiring board, without worrying that other people under the table use the wiring board of oneself to charge.
The specific technical solution of wiring board is one knife switch of setting on plug, has on knife switch and cooperates with iron core
Armature, knife switch is fixed on switch housing by spring, is closed knife switch with hand push button when use, elongates simultaneously
Spring, coil make iron core generate magnetic field, armature engaged therewith are sucked by electric current.Since the suction that iron core generates is greater than bullet
The pulling force of spring, so push-button reset to original position, knife switch is still within closed state even if release button, to guarantee
Open circuit.When the load on circuit is closed, circuital current becomes 0, and iron core no longer generates magnetic field, and knife switch is made in the tension of spring
With lower disconnection circuit.
Detailed description of the invention
Attached drawing 1 is the schematic diagram of wiring board, and Fig. 2 is the enlarged drawing of plug 9.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
The wiring board includes the plug (9), conducting wire (10) and socket (11) of Fig. 1.Wherein, there is a plug-in strip on plug (9)
It switchs (1), knife switch can rotate to realize closure.There is the armature (2) with iron core (7) cooperation on knife switch, plug-in strip is opened
It closes (1) to be fixed on plug (9) by spring (3), and has hand push button (4).When power grid is accessed in wiring board side, side access is used
Electric equipment, when pressing hand push button (4), the coil (8) on iron core (7) alives, and generates attraction to armature (2).Work as suction
When power is greater than the pulling force of spring (3), knife switch (1) can be remained closed.There are spring (4-1), spring inside hand push button (4)
(4-1) plays the function of making push-button reset.When the plug for pulling up electrical equipment, the suction disappearance of coil (8), knife switch (1)
Disconnecting circuit under the pulling force of spring (3).It is wrapped on iron core (7) coil (8), coil (8) is by two from input terminal (5)
Conducting wire is wrapped in the opposite direction on iron core (7), due to two current in wire on the contrary, can generate after winding in the opposite direction double
Times magnetic field.The conducting wire (10) and socket (11) of the wiring board are without particular/special requirement.
Claims (1)
1. a kind of wiring board of induction switching-off, including plug (9), conducting wire (10) and plate (11), it is characterised in that described inserts
Head (9) has a knife switch (1), there is the armature (2) with iron core (7) cooperation on knife switch；The knife switch bullet
Spring (3) is fixed on plug (9)；The knife switch can be connected to input terminal (5) and output end (6)；There is a hand push button
(4), it is characterised in that have spring (4-1) inside the hand push button (4)；The hand push button (4) and knife switch (1)
Cooperation；There is an iron core (7), it is characterised in that the iron core (7) and armature (2) cooperates, and iron core is wrapped coil on (7)
(8)；The coil (8) is made of two conducting wires from input terminal (5)；Described coil (8) winding the number of turns be a circle with
On；Two conducting wires are wrapped in the opposite direction on iron core (7).
