Abstract
The utility model relates to a power plug which solves the problem of the visual display of a plug being correctly connected with a fire wire and a ground wire of power. The utility model is composed of a plug casing and pins, wherein a neon light L which is connected with a resistor R in series is arranged in the plug body, the other end of the neon light L is connected with a pin of the fire wire, and the other end of the resistor R is connected with the ground wire; the other end of the resistor R in the casing of the single-phase two-foot plug is arranged on hardware cloth nets at both sides of the outer side of the casing. The utility model has the advantage of simple structure, can visually display whether the socket power is correct or not, and can ensure the safety of equipment and personnel. Therefore, the utility model is suitably used as a power plug of electric equipment.
Description
The utility model relates to a kind of attaching plug, particularly a kind of safe Single-phase plug.
The electric equipment of people's use at present is more and more, and each electric equipment all has attaching plug, attaching plug has only two kinds of forms substantially, three-pin plug and Two-feet plug, this plug is to make shell and installation pin and power supply wiring by the insulating electrical material to constitute, non-transformer shows on plug, as everyone knows, the electrical equipment that has is to fire, the ground power supply wiring has requirement, in this case, if can not distinguish fire, ground wire and the combined floodgate electricity consumption just has the possibility that burns out electrical equipment, also has a kind of general phenomenon, in every electrical equipment, substantially all be provided with the insurance of insurance, and, cause after the electrical equipment insurance burns out owing to when using and electrical equipment is installed, do not have strictness and significantly connect electric measure as electrical equipment and personal safety, and do not disconnect live wire, thereby cause the generation of electrical equipment and personal safety accident.
The purpose of this utility model is to provide a kind of safe Single-phase plug with common electric connector versatility and display power supply access phase place directly perceived.
The utility model safety Single-phase plug adopts and add the neon lamp series resistor in common electric connector, it not only has common electric connector versatility, and can insert phase place by display power supply, but intuitive judgment inserts the live wire of power supply and the correctness of ground wire, can play the effect of test electroprobe, can bring tangible safe effect to the user.
Fig. 1 is the single-phase three-pin plug circuit theory diagrams of the utility model
Fig. 2 is the single-phase Two-feet plug circuit theory diagrams of the utility model
Below in conjunction with accompanying drawing the utility model is described in further detail:
Be the single-phase three-pin plug of the utility model as shown in Figure 1, it is to be made of plug body and tripod pin, and neon lamp L series resistor R is housed in plug body, the other end of the neon lamp L line pin 1 of starting to exchange fire, the other end earth connection pin 2 of resistance R.Three pin of single-phase three-pin plug insert respectively and connect power firestreak, ground wire, center line in the electric socket, this single-phase three-pin plug is through electric wire circuit closer equipment, generally in electric equipment, ground wire is connected with center line, so when live wire pin 1 connects power firestreak, then neon lamp L is bright, otherwise neon lamp L do not work, and this plug can show the correctness that inserts power firestreak, whether guarantee electric equipment and personal safety, can also show has.Be the single-phase Two-feet plug of the utility model as shown in Figure 2, it is to be made of plug body and two pin pins, on both sides, the plug body outside metal is housed and arranges net 4, neon lamp L series resistor R is housed in plug body, the other end of the neon lamp L line pin 1 of starting to exchange fire, another termination hardware cloth net 4 of resistance R, when the metal outside the people holds plug was arranged net 4 insertion plugs, when connecing power firestreak as live wire pin 1, then neon lamp L was bright, it is correct that expression connects electricity, connects electric mistake otherwise insert attaching plug.This plug can guarantee that electric equipment inserts the correct of power firestreak and ground wire, can guarantee also that insurance in the electric equipment is connected on the live wire to work the safety of the assurance equipment and the person.
Claims (2)
1. safe Single-phase plug, it comprises shell and pin, it is characterized in that being equipped with in plug body neon lamp L series resistor R, the other end of the neon lamp L line pin [1] of starting to exchange fire.
2. according to the described safe Single-phase plug of claim 1, it is characterized in that pin has three or two, another termination hardware cloth net [4] of resistance R in the other end earth connection pin [2] of the resistance R in the three-pin plug shell, Two-feet plug shell, metal arrange net [4] be contained on the lateral surface of shell.
