Abstract
The utility model relates to a duel-voltage two-purpose power socket, which comprises a box body at least provided with a three-phase output socket or a two-phase output socket, and a power input wire connected with the three-phase output socket or a two-phase output socket. The utility model is characterized in that: the power input wire in the box body is connected with a power transformer in parallel; the external surface of the box body is provided with at least a USB socket connected with the output of the power transformer. The duel-voltage two-purpose power socket converts municipal power source into low voltage power source, so as to expand applicable range of power socket. During use, after the high-low voltage power socket is connected with municipal power source, the socket can meet the electric power for TV set, refrigerator, induction cooker and similar household appliances, and also meet electric power for digital camera, MP3, hand-held computer, mobile phone and similar low-voltage appliances. The utility model is a kind of practical power socket that can meet various conventional appliances with different voltage.
Description
Technical field
The utility model relates to the supply socket box, especially a kind of pair of voltage two-purpose socket.
Background technology
Supply socket is an electric equipment power supply connecting device commonly used in the modern life, and it is suitable for the connection of civil power 220V power supply usually and uses.Common supply socket kind is a lot, and the supply socket of three-phase output socket or two-phase output socket is arranged, and has to possess the supply socket of a plurality of three-phases and two output sockets in addition simultaneously for many many output sockets supply sockets of using as electric equipment.These supply sockets have connection output or the simple fuse protection function of finishing power supply.If switch is set in supply socket, then its power turn-on of may command or cut-out.The existing power supply socket can both be realized being switched on or switched off between various electric equipments and the power supply safely, easily.Defective is, the existing power supply socket can only satisfy the configuration of 220V voltage electric equipment usually, and it carries power supply single, can not be the power supply of low-voltage electric equipments such as digital camera, MP3, laptop computer.
The utility model content
The purpose of this utility model is the deficiency that exists at the existing power supply socket box, and a kind of pair of voltage two-purpose socket is provided.
The two voltage two-purpose sockets of the utility model are achieved through the following technical solutions.
This pair of voltage two-purpose socket comprises: be provided with the box body of a three-phase output socket or two-phase output socket at least, the power input line that is connected with three-phase output socket or two-phase output socket.
The characteristics of this pair of voltage two-purpose socket are: be parallel with power transformer on the power input line in the described box body; Cartridge outer surface is provided with a USB socket that is connected with power transformer output at least.
The further characteristics of the two voltage two-purpose sockets of the utility model are:
Also be in series with power control switch on the described power input line, the button of power control switch is arranged on the outer surface of box body.
The utility model beneficial effect compared with prior art is:
This pair of voltage two-purpose socket by power transformer and USB socket are set, utilizes power transformer to convert city's power supply to low-tension supply on the basis that does not influence existing power supply socket box function, expanded the scope of application of supply socket.During use, this high-low voltage power source socket with after the city is electrically connected, can be satisfied the power supply of low-voltage electric equipments such as the power supply of civil power electric equipments such as television set, refrigerator, electromagnetic oven and digital camera, MP3, laptop computer, mobile phone simultaneously.Be a kind of practical more, can satisfy the use supply sockets of powering of existing different voltages all kinds of electric equipments commonly used.
The concrete structure of the two voltage two-purpose sockets of the utility model is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of two voltage two-purpose sockets;
Fig. 2 is the electrical block diagram of shown in Figure 1 pair of voltage two-purpose socket.
Embodiment
Embodiment: can be clear that from Fig. 1 this is two voltage two-purpose sockets, comprising: box body 1, power input line 2 and be arranged on power transformer 3 in the box body 1.Described box body 1 surface is provided with four three-phase output sockets 4 and a power control switch 5, and box body 1 side surface is provided with three USB sockets 6.The circuit structure of described pair of voltage two-purpose socket as shown in Figure 2, power transformer 3 is connected with AC1, the AC2 of power input line 2 with parallel way with four three-phase output sockets 4 and is connected, three USB sockets 6 are connected with the output of power transformer 3, and power input line 2 is serially connected with power control switch 5.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, its framework form can be flexible and changeable, can the subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
Claims (2)
