Abstract
The utility model relates to a power supply plug connector, in particular to a USB charging socket. The USB charging socket comprises a panel and a transformer, wherein a USB interface and a power switch are arranged on the panel; one end of the transformer is connected with an AC circuit, and the other end of the transformer is connected with the USB interface through a lead wire; the power switch is connected in series with the AC circuit and the transformer; and a jack which is a biphase jack or a three-phase jack is formed on the panel. The USB charging socket has a simple structure, is convenient to mount, can output alternate current and direct current at the same time, and satisfies the requirements for not only AC power supply of large-scale electric appliances but also DC power supply of small-sized electronic equipment.
Description
Technical field
The utility model relates to a kind of power supply plug-in unit, is specifically related to a kind of USB charging socket.
Background technology
At present, the AC Power supply socket that is installed in the body of wall is widely used in the daily life.Along with the continuous progress of science and technology, the electronic equipment of the direct current supply of low-voltage or little electric current is used widely, and AC Power supply socket also is not suitable for the low-voltage of direct current supply or the electronic equipment of little electric current.Like this, use DC power supply apparatus to change with regard to needs.DC electronic equipment on the market all can directly be supplied power through USB interface connection DC power supply apparatus now.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of USB charging socket.
The technical scheme of the utility model is: a kind of USB charging socket comprises panel and transformer.USB interface and mains switch are set on the said panel.Said transformer one end connects alternating current circuit, and the other end connects USB interface through lead; Said mains switch is connected with alternating current circuit and transformer.On the said panel jack is set, jack is two phase jacks or three-phase jack.
The utility model is simple in structure, easy for installation, and ability is output AC electricity and direct current simultaneously, can not only satisfy the Alternating Current Power Supply of large electric appliances, can satisfy the direct current supply of miniaturized electronics simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the circuit diagram of the utility model.
Wherein, 1, alternating current circuit, 2, transformer, 3, lead, 4, USB interface, 5, mains switch, 6, jack, 7, panel.
Embodiment
Specify the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, the utility model comprises panel 7 and transformer 2.USB interface 4 and mains switch 5 are set on the said panel 7.Said transformer 2 one ends connect alternating current circuit 1, and the other end connects USB interface 4 through lead 3; Said mains switch 5 is connected with alternating current circuit 1 and transformer 2.On the said panel 7 jack 6 is set, jack 6 is two phase jacks or three-phase jack.
During use, closed mains switch 5 inserts USB interface 4 with equipment to be charged, and transformer 2 converts alternating current into direct current output power supply.After finishing using, disconnecting power switch 5 gets final product.Alternating Current Power Supply directly inserts in the jack 6 and gets final product.
