Description
Technical field
The utility model relates to the supply unit field, is a kind of wall simple in structure and easy to use or socket supply unit specifically.
Background technology
Existing wall or socket power supply generally are with the form that single channel inserts or the copper sheet plug connector connects, and the alternating current 220V power supply is inserted in switch or the socket.But this wall or socket power supply exist a unsurmountable defective, are exactly that its voltage and electric current all only are applicable to the ac electric apparatus element.For the lower dc electric apparatus element of some voltages and current requirements (as mobile phone etc.), must be equipped with the correspondent voltage current converter as need charging or electricity consumption, except losing easily, also take many usage spaces, so it uses very trouble.And the USB power supply is stablized the both low direct current that forces down stream because of it is exportable, and can satisfy the charging or the need for electricity of most of dc electric apparatus element, progressively is subjected to people's favor.How USB power supply and AC power are combined, become the technical barrier of wall or socket power supply development, therefore, present wall or socket power supply architecture still await further improvement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, easy to use and safe and reliable wall or socket supply unit are provided.
Goal of the invention of the present utility model is achieved in that a kind of wall or socket supply unit, the interchange input module and the AC output module that comprise mutual electrical connection, it is characterized in that: be provided with the DC conversion modules and the direct current output module of mutual electrical connection in described wall or the socket supply unit, DC conversion modules with exchange input module and be electrically connected.
Described DC conversion modules comprises the capability correction module of mutual electrical connection and from the motional feedback circuit module.
Described capability correction module is made up of the capability correction IC and the bipolar voltage switch of mutual electrical connection.
Describedly form by the over-current overvoltage protector that is connected in series, protective tube and safety electric capacity from the motional feedback circuit module.
Described direct current output module is at least one USB lead-out terminal.
Described USB lead-out terminal is for being connected in parallel.
Wall of the present utility model or socket supply unit improve prior art, the DC conversion modules and the direct current output module of mutual electrical connection are set in supply unit, and DC conversion modules is electrically connected with exchanging input module, and DC conversion modules comprises the capability correction module of mutual electrical connection and from the motional feedback circuit module.By DC conversion modules the alternating current that inserts is converted to the direct current of low pressure constant current, and through the output of direct current output module, this structure can make supply unit be used in the occasion of multiple AC and DC electricity and usefulness.By direct current being exported to the USB terminal.Make its charging that is applicable to multiple low pressure current stabilization, electricity consumption occasion, its use is very simple.In addition, supply unit fail safe and reliability in use can be effectively ensured from the motional feedback circuit module, user's Electrical Safety can be guaranteed by what the over-current overvoltage protector that is connected in series, protective tube and safety electric capacity were formed.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in 1, wall of the present utility model or socket supply unit mainly comprise interchange input module 1, AC output module 2, DC conversion modules and direct current output module 4 with reference to the accompanying drawings.Wherein exchange input module 1 and be electrically connected with AC output module 2 and DC conversion modules respectively, DC conversion modules and direct current output module 4 are electrically connected.DC conversion modules is formed by capability correction module 31 with from motional feedback circuit module 32, capability correction module 31 be connected each other from motional feedback circuit module 32.Capability correction module 31 is made up of capability correction IC311 and bipolar voltage switch 312, this capability correction IC311 and bipolar voltage switch 312 are electrically connected each other, capability correction module 31 can be adjusted electric current automatically by the variation of bearing power, guarantees supply unit output constant current DC power supply.Then form from motional feedback circuit module 32 by over-current overvoltage protector 321, protective tube 322 and safety electric capacity 323; over-current overvoltage protector 321, protective tube 322 and safety electric capacity 323 are connected in series, and can realize over-voltage and over-current, short circuits and protection such as open circuit by over-current overvoltage protector 321, protective tube 322 and 323 pairs of loads of safety electric capacity from motional feedback circuit module 32.Direct current output module 4 is made up of at least one USB lead-out terminal, and the USB lead-out terminal is for being connected in parallel, and the USB lead-out terminal has enlarged the scope of application of supply unit applicable to charging, the electricity consumption occasion of multiple low pressure current stabilization.
Above-mentioned specific embodiment only is the utility model effect embodiment preferably, and wall all and of the present utility model or the identical or equivalent configurations of socket supply unit are all in protection range of the present utility model.
