Description

Circumscribed variable-voltage power supply socket

Technical field

The utility model relates to a kind of supply socket, the particularly a kind of external socket that can realize transformation.

Background technology

Under the joint efforts of this several years electronic product personages in the field of business and engineers, present development rapidly, especially the great renewal and the function of information and communication Related product constantly expand, and make the interface equipment of various function inequalities add utilization ranks such as computerized information, communication and audiovisual in succession.For example; Tabulating machine, laptop computer, scanner, external drive, hub, calculating punch, digital camera, broadcast loudspeaker, MP3 player, network video, Wireless Keyboard, wireless mouse, charger for mobile phone, PDF browser products such as (PDF:Portable Document Format, Portable file formats).

But the peripheral apparatus of aforementioned calculation machine, the communication apparatus and audio-visual products especially with the product of DC power supply as working power, all must provide enough direct currents just can make the product operate as normal.

Aforementioned calculation machine peripheral apparatus, the communication apparatus and audio-visual products obtain the method for power supply, are connected with AC outlet with the power of transformer line by an end usually, and alternating current converts direct current to through this transformer and supplies with this equipment use; Or the rechargeable battery with energy storage function is set in equipment, and by this transformer with the alternating current transformation after to this rechargeable battery charging, be the supply of equipment DC power supply by rechargeable battery then.

Thisly convert alternating current to the direct-current power supply product and use, or with DC power supply direct-current power supply product use with correct magnitude of voltage and current value after transformation, can cause in the AC power cord gang socket or be abound with transformer or plug on the powered by direct current socket, and the power line that respectively is connected to ancillary equipment will form complicated dish knot, and the charge capacity in the rechargeable battery must just can charge by above-mentioned charger with transformer device structure when using up.Bring inconvenience for the use of these computer peripheral equipments, the communication apparatus and audio-visual products.

Though many in addition electric products adopt alternating current, but because of various countries or various places voltage specification different again, specification such as 220V, 110V for example, therefore equally all use AC power, but still must could use through transformation, especially journey abroad is generally all will prepare various power transformer, so that can use local power supply.

The another kind of situation that may occur is that on-the-spot only have DC power supply but the product needed alternating current of use, for example; On automobile, use dust catcher, light or the sound equipment etc. of alternating current, therefore, the equipment that direct current is converted to alternating current must be arranged.

No matter the conventional power source supply system is that (AC is an alternating current for the transformation of AC/AC, AC/DC, DC/DC, DC/AC or conversion, DC is a direct current), all must need corresponding transformer or transducer and can provide the power supply that can directly use for the user, cause the number of transformer or transducer too many, use very inconvenient.

The utility model content

The purpose of this utility model is to provide a kind of circumscribed variable-voltage power supply socket, directly carries out AC-DC conversion, voltage adjustment by this circumscribed variable-voltage power supply socket, to obtain required power supply.

For reaching above-mentioned purpose of design, the utility model adopts following technical scheme: this circumscribed variable-voltage power supply socket comprises alternating current input or direct current input, and at least one alternating current output or DC output end after transformation;

This circumscribed variable-voltage power supply socket comprises base plate, is fixed on circuit board and upper shell cover on the base plate, wherein comprises dc supply input or ac power input end, indicator light, transformer, capacitor, pressurizer on the circuit board, at least one exports the ac output end of different magnitudes of voltage and current value through the dc output end of different magnitudes of voltage of output and current value after the transformation or at least one after transformation;

Wherein, transformer is for exchanging input/interchange output transformer, exchanging input/direct current output transformer, direct current input/direct current output transformer or direct current input/interchange output transformer.

By the power supply (can be AC power also can be DC power supply) of the described circumscribed variable-voltage power supply of technique scheme socket, in this circumscribed variable-voltage power supply socket, just convert suitable out-put supply (can be that AC power also can be a DC power supply) to input.This way makes a lot of electrical equipment, not need just can directly use through power source conversion during power supply in input, has saved transformer and transducer, make can not be covered with transformer or transducer on the socket, so that more convenient to use.
