Abstract
The utility model relates to a multipurpose changeover plug with a power-on indicating lamp, which is characterized in that the power-on indicating lamp (4) is connected between an N pole circuit and an L pole circuit in a plug. The utility model has the advantages of simple structure, convenient operation and strong applicability.
Description
The utility model relates to the plug that general electrical equipment is used.
At present, the plug that general electrical equipment is used, effect has only a kind of, promptly is to play the effect that connects power line to an electrical equipment, and when using this plug, the circuit of socket has and do not have electricity is unknown, can only lean on voltage test pencil just can detect.Particularly electrical equipment does not during normal use have electricity suddenly, and this is the mains failure of big electrical network on earth, and it is all unknown that the electrical equipment in also being to use has been broken, and therefore, it is inconvenient that the user feels.
The purpose of this utility model provides the plug that a kind of general electrical equipment is used, if with this plug be inserted into all can know at once on any one socket this socket have do not have charged.
Technical solution of the present utility model is such, at the plug box and the lid of existing plug, pin, two pole sockets, on the basis of band ground connection two utmost point multipurpose sockets, the utility model in plug N polar curve road and L polar curve road between be connected with electromotion pilot lamp.
Operation principle of the present utility model is behind plug insertion socket, the N utmost point of plug links to each other with the corresponding circuit of socket respectively with the pin of the L utmost point, the electromotion pilot lamp that is connected between the N polar curve road of plug and the L polar curve road is promptly bright like this, and when socket did not have electricity, electromotion pilot lamp just can not be bright.
The utility model has the advantages that only plug of the present utility model to be inserted in and know at once all on any one socket whether socket has electricity, and this has brought convenience and safety to the user.The utility model is simple in structure, and is easy to use, and applicability is strong.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 plug of the present utility model front organigram;
Fig. 2 pin position view of the present utility model;
Fig. 3 electrical equipment joint construction of the present utility model schematic diagram.
Shown in Fig. 1,2,3, the utility model has the plug box and the lid of a plastic casing, is fixed with two pole sockets 2 and band ground connection two utmost point multipurpose sockets 3 on the front of plug box, is fixed with pin 1 on relevant position on the bayonet cap.In the plug box of plug, the N utmost point of two pole sockets has a copper bar to be connected with the N utmost point of band ground connection two pole sockets; And the L utmost point also has a copper bar to be connected with the L utmost point of band ground connection two pole sockets, and is connected to two of electromotion pilot lamp by this two copper bar and extremely goes up.An aperture is arranged at the bottom at the plug box of plug, and electromotion pilot lamp 4 can be embedded in the aperture on the plug box.
Claims (2)
1, the band electromotion pilot lamp is used changeover plug more, comprises plug box and lid, pin (1), two pole sockets (2), and band ground connection two utmost point multipurpose sockets (3) is characterized in that being connected with electromotion pilot lamp (4) between N polar curve road in plug and the L polar curve road.
2, band electromotion pilot lamp according to claim 1 is used changeover plug more, it is characterized in that electromotion pilot lamp (4) can be embedded in the aperture on the plug box.
