[Bei Jing Ji Intraoperative]
3-phase plug is three characteristics of the middle term power supply and arranging, 380V AC power is provided together with three-phase socket, it is the necessary device that convenient power supply is provided for three phase electric equipment, three-phase socket comprises base and the metal contact with terminal fixed thereon, with have and the shell of the corresponding jack of each contact, also have two to insert seat, its corresponding contact is connected and is formed a kind of two complementary insertion seats by conducting strip, and between each jack, is provided with division board inside shell.
At present, three plugs of 3-phase plug line of starting to exchange fire respectively, zero line and ground wire, three plugs of biphase plug start to exchange fire respectively line and zero line, for some powerful electrical appliances, because of its electric current larger, leakage current is directly directed to the earth via the ground portion of 3-phase plug and human body only in order to prevent electric leakage from threatening user's personal safety, avoid user's life to be on the hazard safely, and on the contrary, less for some power, the also little electrical equipment of electric current when use, can not threaten safely and the electrical appliance that injures can use biphase plug to user's life.
At present, biphase plug and 3-phase plug be corresponding two-phase socket and three-phase socket respectively, can not meet user demand and two-phase socket has vacant when three-phase socket is less, for example, while charging, prior art has no invention or relevant report for biphase plug and the simultaneous plug of 3-phase plug, causes awkward phenomenon to happen occasionally.
[summary of the invention]
For the problems referred to above, the purpose of this utility model is mainly to provide a kind of plug that has biphase plug and 3-phase plug simultaneously, has practicality concurrently.
For achieving the above object, the utility model provides a kind of plug, be used for inserting a socket to an electrical appliance power supply, header body comprises 3-phase plug and biphase plug, biphase plug is provided with the first zero line inserted sheet and the first live wire inserted sheet, 3-phase plug is provided with the second zero line inserted sheet, the second live wire inserted sheet and ground wire inserted sheet, header body is provided with a storage tank, this biphase plug or this 3-phase plug are placed in this storage tank, pull out biphase plug or the 3-phase plug in this storage tank and insert this socket, giving this electrical appliance power supply.
Especially, when in described storage tank when accommodating this biphase plug, this 3-phase plug is located in this header body, and this biphase plug or this 3-phase plug insert this socket to this electrical appliance power supply; When in described storage tank when accommodating this 3-phase plug, this biphase plug is located in this header body, and this 3-phase plug or this biphase plug insert this socket to this electrical appliance power supply.
Especially, in the time using described biphase plug, described the first zero line inserted sheet is connected with the zero line side of this socket, and described the first live wire inserted sheet is connected with the live wire end of this socket.
Especially, in the time using 3-phase plug, described the second zero line inserted sheet is connected with the zero line side of this socket, and described the second live wire inserted sheet is connected with the live wire end of this socket, and described ground wire inserted sheet is connected with the ground terminal of this socket.
Compared to prior art, plug of the present utility model, there is biphase plug and 3-phase plug simultaneously, make this plug can insert the power supply of two-phase socket, can insert again three-phase socket power supply, avoid can not meeting user demand and two-phase socket occurs that when vacant, awkward drawback, has practicality relatively when three-phase socket.
