Abstract

The utility model provides a voltage adjustable socket, which comprises a casing; a voltmeter, a USB interface, a voltage adjusting button and a sliding groove are arranged on the casing; a primary coil and a secondary coil are arranged in the casing; a sliding piece is connected with the primary coil in a sliding manner, and is isolated from the voltage adjusting button and fixedly connected with that; the wiring terminal of the sliding piece and one wiring terminal of the secondary coil are electrically connected with the USB interface through a diode; the two ends of the USB interface are electrically connected with the voltmeter; the coil turn ratio of the primary coil to the secondary coil is changed through moving the sliding piece by the volt adjusting button, thus the output voltage of the secondary coil is changed; the output of DC voltage can be adjusted through the USB interface; and the voltmeter displays the intensity of the output voltage. Therefore, electronic products do not need special chargers, and only a data cable is required to achieve the charging function, and the utility model has the advantages of wide application range and high universality.

Description

The voltage adjustable socket

Technical field

The utility model relates to a socket, specifically, relates to a kind of voltage adjustable socket.

Background technology

At present, electronic product is of a great variety, the sub-product of different manufacturer's institute's electrogenesis, because electron trade does not have the unified standard of standard charger, the difference of charger required voltage and structure causes charger of a great variety, so both cause waste of material, brought inconvenience for people's use again.

The utility model content

Problem to be solved in the utility model is at above deficiency, and a kind of highly versatile is provided

The voltage adjustable socket.

For solving above technical problem, the technical solution adopted in the utility model is as follows: the voltage adjustable socket, comprise housing, it is characterized in that: housing is provided with voltmeter, USB interface, voltage-regulation button and chute, be provided with primary coil and secondary coil in the housing, slidely connect slide plate on the secondary coil, insulation and fixedlying connected between slide plate and the voltage-regulation button, a binding post of the binding post of slide plate, secondary coil connects USB interface through diode electrically, and the two ends of USB interface are electrically connected voltmeter.

The utility model adopts above technical scheme, compared with prior art, have the following advantages: can move slide plate by the voltage-regulation button, change the coil ratio of primary coil and secondary coil, thereby change the output voltage of secondary coil, realize the output of adjustable dc voltage by USB interface, voltmeter shows the size of output voltage, makes electronic product needn't use special charger, only needs a data lines can realize charge function, applied range, highly versatile.

Below in conjunction with drawings and Examples the utility model is further specified.
