Abstract
The utility model provides a super test pencil, which comprises a first metal pin, a second metal pin, a first neon tube, a second neon tube, a first current limiting resistor, a second current limiting resistor, a metal contact and an outer casing. The first metal pin, the first neon tube and the first current limiting resistor are sequentially connected with each other and then connected with the metal contact, and the second metal pin, the second neon tube and the second current limiting resistor are connected with each other sequentially and then connected with the metal contact. The super test pencil can judge live wire jacks from zero wire jacks in a socket at one step after being plugged into the tested socket, or judge whether the socket is electrified or not, or judge whether the socket is connected with a direct-current power source or not.
Description
Technical field
The utility model relates to a kind of electrical equipment, especially a kind of super electroscope.
Background technology
Present electroscope is mainly by the metal pin nib, neon tube or liquid crystal device, current-limiting resistance, metal contact is in series, be used to check the electric power situation in the receptacle sockets under a lot of situations, its using method is as follows: the metal pin nib of electroscope is stretched in the jack, touch metal contact with hand then, then if be live wire in the jack that the metal pin nib is touched, it will pass through electroscope, human body constitutes a loop with the earth, and neon tube is luminous, if in this jack is zero line, perhaps whole socket outage, then neon tube is not luminous, in addition, if socket provides the direct current of non-ground connection, then neon tube is not luminous yet, therefore, and when electroscope is not luminous, then need electroscope inserted in another jack and measure, if still not luminous, still can not judge no power in the socket fully, therefore, when adopting present electroscope to carry out electrical verification, not only comparatively bother, and in comparatively complicated electric power system, can't accurately judge the electric power situation of tested socket (joint).
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of super electroscope, and this super electroscope can be after inserting tested socket, disposable firewire jack and the zero line jack of judging in the socket, whether perhaps charged in the socket, perhaps whether socket connects direct supply.
The technical scheme that its technical matters that solves the utility model adopts is: this super electroscope comprises metal pin, neon tube, current-limiting resistance, metal contact, shell, described metal pin comprises first metal pin and second metal pin, described neon tube comprises first neon tube and second neon tube, described current-limiting resistance comprises first current-limiting resistance and second current-limiting resistance, described first metal pin, first neon tube, after being linked in sequence, first current-limiting resistance connects metal contact again, described second metal pin, second neon tube, after being linked in sequence, second current-limiting resistance connects metal contact again.
As preferably, described metal contact is embedded on the shell.
As preferably, described shell is a plastic casing.
As preferably, described first metal pin, second metal pin are arranged side by side along described shell center line, and described first neon tube, second neon tube also are arranged side by side along described shell center line.
As preferably, described first current-limiting resistance, the second current-limiting resistance resistance equate, all between 1M Ω～3M Ω, described first neon tube, the second neon tube specification are identical, and the resistance during two neon tube build-ups of luminance is all between 1M Ω～2M Ω.
As preferably, described first metal pin (1), second metal pin (2) shape are identical, are the prolate strip.
The beneficial effects of the utility model are: this super electroscope is connected on when using, can insert two metal pin of electroscope in the socket simultaneously, if be provided with live wire in the first metal pin place jack, then have only first neon tube luminous, (human body resistance is about 2K Ω to second neon tube by the human body short circuit, compare with the striking resistance of second current-limiting resistance and second neon tube, can ignore), if be provided with live wire in the second metal pin place jack, then have only second neon tube luminous, if in the socket energising is not arranged, then two neon tubes are all not luminous, if be connected with non-ground connection type direct current in the socket, then two neon tubes are all luminous, and this super electroscope can be after inserting tested socket, disposable firewire jack and the zero line jack of judging in the socket, whether perhaps charged in the socket, perhaps whether socket connects direct supply.
