Technical Field

The invention relates to the technical field of mobile phone charging, in particular to a mobile phone charging plug capable of automatically cutting off a power supply.

Background

A mobile phone, which is called a mobile phone or a wireless phone, is generally called a mobile phone, and originally is a communication tool, and has a popular name of large brother in the early stage, and is a portable phone terminal that can be used in a wide range, and is used by supplying power from a battery, whereas in the prior art, a mobile phone usually uses a mobile phone charger to supplement lost electric quantity and is reused:

in practical use, a user usually inserts a charger into a mobile phone before sleeping and then charges the mobile phone for a whole night, and the mobile phone has the defects that after the mobile phone is fully charged, the charging state of a power supply is automatically detected by a general mobile phone, and after the mobile phone is fully charged, the power supply is automatically cut off.

Disclosure of Invention

The invention aims to solve the problem that in the prior art, a plurality of charging and charging stopping processes can occur in the charging process of a mobile phone, and provides a mobile phone charging plug capable of automatically cutting off a power supply.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a from cell-phone charging plug of cutting off power, includes shell, inserted sheet and connecting wire, set up the cavity in the shell, sealed sliding connection has the slide in the cavity, one side that the slide is close to the inserted sheet is equipped with the fixed plate, the fixed plate is connected with the inserted sheet electricity, the slide is connected with the connecting wire electricity, the slot has been seted up respectively to the both sides that the slide is connected with the cavity, sliding connection has the stopper in the slot, the bottom fixedly connected with expanding spring of stopper, expanding spring's bottom fixed connection is in the bottom of slot, the cavity corresponds stopper one side inner wall and sets up the spacing groove of mutually supporting with the stopper, the one end fixedly connected with compression spring of fixed plate is kept away from to the slide, compression spring's other.

In the above-mentioned cell-phone charging plug of self-cutting off power, compression spring connects and inlays the condenser of establishing at the cavity lateral wall, the condenser is kept away from compression spring's one end intercommunication and has been seted up the drive chamber, drive chamber fixedly connected with electro-magnet and electro-magnet are connected with the permanent magnet board through the torsional spring rotation, the permanent magnet board is connected with the condenser electricity and is repelled with the electro-magnet homopolar mutually.

In the mobile phone charging plug capable of automatically cutting off the power supply, the compression spring is always kept in a compressed state, a lead which is the same as the compression spring in path is embedded in the compression spring and is wrapped in the compression spring through an insulating material, and the lead in the compression spring, the capacitor and the inserting piece form a closed loop together.

Compared with the prior art, the invention has the advantages that:

1. in the invention, after the shell 1 and the plug-in sheet 2 of the charger are inserted into a power supply, the sliding plate and the fixed plate can be butted and connected by compression between the compression spring and the sliding plate in a normal charging state, and in the state, the power supply is communicated with a mobile phone through the fixed plate and the sliding plate to carry out normal charging;

2. after the charging is finished, the circuit is disconnected by the internal element of the mobile phone, the plug-in piece is still inserted into the socket of the power supply at the moment, the current in the connection of the sliding plate and the fixed plate has an instantaneous disconnection state, the current in the capacitor is output through the branch circuit connected with the electromagnet and the capacitor under the state, so that the compression spring has a state of short-time contraction under the action of the current, the sliding plate moves to a state that the limiting block is matched with the limiting groove under the state, and after the electric quantity in the capacitor is consumed, the sliding plate always keeps the disconnection state with the fixed plate under the mutual limiting of the limiting block and the limiting groove, so that the self-power-off effect is realized;

3. the electromagnet and the permanent magnet plate which repels the same poles of the electromagnet are arranged, so that the electromagnet is electrified by a power supply to enable the permanent magnet plate to be kept away from one side of the electromagnet and connected with the capacitor, the capacitor can be normally charged and discharged, and after the inserting piece leaves the power supply, the electromagnet is powered off to attract the permanent magnet plate, so that the capacitor is disconnected from a circuit connected with a lead in a compression spring, the process cannot be carried out, the plug state and the battery full charge state are effectively and respectively pulled out, and the use is convenient;

4. because spacing between stopper and the spacing groove is more weak, consequently when needs continue to charge, only need slightly rock the shell of charger, can be with two stoppers to fixed plate direction roll-off under compression spring's effect to realize being connected of fixed plate and slide, carry out the effect that continues to charge, and the function of carrying out the self disconnection after being full of electricity has also improved mobile phone battery's life, avoids repeated charging many times, causes the loss to the battery.
