Abstract
The utility model provides a mobile phone charger with an automatic switch. Charging wires are connected between a voltage stabilizing circuit and a charging plug. Switch wires are connected between power supply pins and an automatic switch. The metal movable key of the automatic switch and the charging plug are arranged side by side, and the outside exposed length of key is shorter than the exposed length of the charging plug. In the internal part of an insulated shell 1, one power supply pin is connected to the voltage stabilizing circuit, the other power supply pin is connected to a static contact in an insulated shell 2 through a switch wire, a moving contact is fixed at the right side of the upper surface of the metal movable key, the left side of key is connected to one end of a metal spring, and the other end of the metal spring is connected to the voltage stabilizing circuit through the other switch wire. When the charging plug is inserted into a mobile phone for charging, the movable key is pressed by a shell at the same time, the spring is shortened, the moving contact and the static contact are in contact, the whole circuit is energized to work, and the mobile phone is charged. After the charging plug is pulled, the movable key is pushed away by the spring, the moving contact and the static contact are separated, the whole circuit is powered off, an indication lamp and the voltage stabilizing circuit do not work, and a purpose of leaving the charger on a power supply socket without consuming electrical energy is achieved.
Description
Technical field
The utility model relates to a kind of device charging the phone, and especially can save electric energy, and mobile phone when charging automatic processing circuit, the band automatic switch charger of automatic shutoff circuit while charging.
Background technology
At present, known charger for mobile phone is made up of voltage stabilizing circuit, indicator light, the outer parts such as wire and charging plug that connect in insulation crust, power pin, shell, as the corollary apparatus of mobile phone, in the time that mobile phone does not have electricity, can charge the phone with it whenever and wherever possible, normally use mobile phone to bring great convenience to people.But the various charger for mobile phone that use now all do not arrange switch, after mobile phone is full of electricity and mobile phone is taken off, people are often disinclined to charger to pull up from supply socket, although now charger is in Light Condition, in shell, voltage stabilizing circuit, indicator light, still in energising, are also consuming electric energy, of long duration, quantity is many, and the electric energy that accumulative total consumes is also very considerable, therefore, charger for mobile phone, in energy-conservation unfavorable, has deficiency in fact now.
Utility model content
In order to overcome now charger for mobile phone owing to there is no switch, the deficiency that still can consume electric energy after mobile phone takes off in supply socket, the utility model provides a kind of band automatic switch charger for mobile phone, this charger is energy automatic processing circuit in the time that mobile phone charges, mobile phone takes off afterwards automatic shutoff circuit immediately, even if stay for a long time in supply socket and also can not consume any electric energy, give the energy-conservation great convenience of bringing.
The utility model solves the technical scheme that its technical problem adopts: entirety is made up of insulation shell one, two power pins, voltage stabilizing circuit, indicator light, charging conductor, switch wire, charging plug, automatic switch and insulation shells two.Two power pins be arranged in parallel, are fixedly mounted on insulation shell one, and expose one end, within the other end stretches to insulation shell one; Voltage stabilizing electrical equipment is arranged on exhausted level shell one inside; Indicator light is connected with voltage stabilizing circuit; One end of charging plug is fixed on insulation shell two inside, and the other end exposes; Two of charging conductors, are connected between the output and charging plug of voltage stabilizing circuit; Two of switch wires, are connected between power pin and automatic switch; Automatic switch is made up of metal spring, movable metallic key, fixed contact and moving contact, wherein metal spring, fixed contact are arranged on the inside of insulation shell two, one end of movable metallic key is arranged on insulation shell two inside, the other end is exposed on the external, and this key and charging plug are arranged side by side, and can on insulation shell two, do into and out of activity, the length that the Length Ratio charging plug that movable metallic key is exposed on the external exposes is short; In insulation shell one inside, wherein a power pin is connected with voltage stabilizing circuit, and another power pin is connected with the fixed contact of insulation shell two inside through a switch wire wherein; Moving contact is fixed on the upper surface right side of movable metallic key in insulation shell two inside, and this upper surface left side is connected with one end of metal spring, and the other end of metal spring is connected with voltage stabilizing circuit through another root switch wire.When mobile phone charging, charging plug inserts mobile phone socket, meanwhile casing is depressed movable metallic key, metal spring in automatic switch is compressed, moving contact is contacted with fixed contact, whole circuit is connected, indicator light is bright, voltage stabilizing circuit work, mobile phone is in charged state, complete when charging, charging plug is extracted from mobile phone, the metal spring in automatic switch loosens, draw key is pushed open, make moving contact depart from fixed contact, whole down circuitry, voltage stabilizing circuit, indicator light is neither worked, thereby reach charger and stayed for a long time the object that does not consume electric energy in supply socket.
The beneficial effects of the utility model are, when mobile phone charging, circuit is connected automatically, charging plug is after mobile phone is extracted, and circuit disconnects automatically, and the voltage stabilizing circuit in charger and indicator light all power-off are not worked, even if charger is stayed for a long time and is not also consumed electric energy in supply socket, only automatic switch and charging plug are arranged side by side, and in automatic switch, metal spring is set, draw key and dynamic and static contact, simple in structure.
