Description

A household two-phase, three-phase dual-purpose electric wire extension cord

technical field

The utility model relates to an electric wire extension cord, that is, a household two-phase and three-phase dual-purpose electric wire extension cord.

Background technique

In daily family life, there are often situations where the socket is outside the length of the power cord that is equipped with the electrical appliance, especially for large appliances that are not easy to move such as refrigerators and washing machines, it is very inconvenient to use in this case. In view of this situation, there are usually two solutions: one is to use a plug-in board to connect the electrical appliance to a fixed socket, and the other is to use a wire to extend the power cord of the electrical appliance. The first method causes a waste of resources on the plug board when only one electrical appliance is powered or few electrical appliances are powered, and the second method is cumbersome to operate.

Contents of the invention

The purpose of the utility model is to provide a two-phase and three-phase dual-purpose electric wire extension cord which is easy to operate, fast, safe, low in price and has no length limitation.

The utility model adopts following technical scheme for solving technical problems:

The structural features of the utility model is a two-phase and three-phase dual-purpose electric wire extension cord for household use: it includes five major parts: a two-phase plug, a two-phase socket, a three-phase plug, a three-phase socket and electric wires.

The two-phase plugs, two-phase sockets, three-phase plugs, and three-phase sockets meet the requirements of the national standard. The two-phase plug faces match the two-phase sockets, and the three-phase plug faces match the three-phase sockets. The socket, the three-phase plug can be inserted into the three-phase socket.

Three-phase plug wiring has neutral wire, live wire and ground wire, two-phase plug wiring has neutral wire and live wire, the neutral wire of the two-phase plug is connected with the neutral wire of the three-phase plug, and the live wire of the two-phase plug is connected with the live wire of the three-phase plug connect.

When using, if the appliance is a two-phase appliance, insert the power plug of the appliance into the two-phase socket of the extension cord, and insert the two-phase or three-phase plug into a fixed socket; if the appliance is a three-phase appliance, insert the power plug of the appliance Insert this extension cord into a three-phase socket, and insert the three-phase plug into a fixed socket. If one extension cord still cannot achieve the purpose, you can insert the three-phase plug of another extension cord into the three-phase socket of the previous extension cord to extend the wiring. By analogy, if the purpose is still not achieved, you can continue to connect the extension cord until the purpose of supplying power to two-phase electrical appliances or three-phase electrical appliances is achieved.

The extension cord is 10 meters long, and the purpose of supplying two-phase electrical appliances or three-phase power supply can be achieved within three extension cords in general residences.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

In conjunction with Fig. 1, the embodiment of the present utility model is described in detail.

As shown in Figure 1, the household two-phase, three-phase dual-purpose electric wire extension cord comprises two-phase plug 3, two-phase socket 1, three-phase plug 5, three-phase socket 4, electric wire 2 five major parts.

When in use, if the electrical appliance is a two-phase electrical appliance, insert the power plug of the electrical appliance into the two-phase socket 1 of the extension cord, and insert the two-phase plug 3 or the three-phase plug 5 into a fixed socket; The power plug of this extension cord is inserted into the three-phase socket 4, and the three-phase plug 5 is inserted into a fixed socket. If an extension cord still cannot achieve the purpose, the three-phase plug 5 of another extension cord can be inserted into the three-phase socket 4 of the last extension cord to extend the wiring. By analogy, if the purpose is still not achieved, you can continue to connect the extension cord until the purpose of supplying power to two-phase electrical appliances or three-phase electrical appliances is achieved.
