The utility model provides a leakage indicator for an electrical appliance shell, belongs to an electricity test device, and comprises a current-limiting resistor, an indicator light and a grounding body. The current-limiting resistor, the indicator light and the grounding body are connected in sequence, and the current-limiting resistor and the indicator light are arranged on a base body which comprises a magnetic metal body electrically connected with the current-limiting resistor. The leakage indicator can be conveniently installed on the surface of the electrical appliance shell and performs real time monitoring for an electrification status of the electrical appliance shell, thereby guaranteeing safety of an electrical appliance.
Description
Affiliated technical field
The utility model relates to a kind of Electric tester, particularly, is a kind of indicator that is used to detect the electric leakage of electrical equipment shell, comprises current-limiting resistance and pilot lamp.
Background technology
For most industry or domestic electric appliance, adopt the iron shell parcel, after the long-term use of electrical equipment, under the situation that internal circuit is damaged, the electrical equipment shell is charged easily, and then may cause electric shock phenomenon if touch human body this moment.
For the situation whether electric appliance casing leaks electricity, the present method of inspection is, adopts electroscope contact electrical equipment shell, if neon tube is luminous, then the electrical equipment shell is charged, need arouse vigilance, and take safety measures.Yet, in actual production or life process, can not carry electroscope at any time detects in real time to the electrical equipment shell, particularly for household electrical appliance, after the user, just can find its leaky at electric leakage electrical equipment shell electricity often, therefore, even electroscope for the detection of electrical equipment shell leaky shortcoming to some extent in actual production or life.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of electrical equipment shell leakage detector, and this indicator can be installed on electrical equipment shell surface easily, the charged situation of electrical equipment shell is monitored in real time, thereby guaranteed electrical safety.
The technical scheme that its technical matters that solves the utility model adopts is: this electrical equipment shell leakage detector comprises current-limiting resistance, pilot lamp, the grounding body that order is joined; Described current-limiting resistance and pilot lamp are arranged on the pedestal, and this pedestal comprises a magnetic metal body that is electrically connected with described current-limiting resistance.
As preferably, described pedestal also comprises a transparency protected shell, and described magnetic metal body is oblate shape, and described containment vessel covers on the described magnetic metal body, and with described current-limiting resistance and pilot lamp parcel.
As preferably, described grounding body is a metal rib piece, and is connected by flexible circuit conductor between the described pilot lamp.
As preferably, described pilot lamp is a neon tube.
As preferably, described pilot lamp is the flicker diode.
The beneficial effects of the utility model are: this electrical equipment shell leakage detector in use, can pedestal be adsorbed on electrical equipment shell surface for a long time by described magnetic metal body, again described grounding body is positioned over ground, in case electrical equipment shell electric leakage, then pilot lamp will be luminous, thereby cause user's vigilance, and take corresponding safety practice, in optimal way, described magnetic metal body is oblate shape, the easier electrical equipment shell that is adsorbed in, described grounding body adopt metal rib piece then can make it to be difficult for rolling, and described pilot lamp adopts the flicker diode then more can improve warning function.
Description of drawings
Fig. 1 is the outside drawing of an embodiment of this electrical equipment shell leakage detector.
Fig. 2 is the circuit structure diagram of Fig. 1 embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1-Figure 2 shows that embodiment one of the present utility model, in embodiment one, this electrical equipment shell leakage detector comprises current-limiting resistance 5, pilot lamp 2, the grounding body 4 that order is joined; Described current-limiting resistance 5 and pilot lamp 2 are arranged on the pedestal; this pedestal comprises a magnetic metal body 1 that is electrically connected with described current-limiting resistance 5; for the ease of being adsorbed on the electrical equipment shell; this magnetic metal body 1 is oblate shape; it constitutes described pedestal with the transparency protected shell 11 that covers on self side is common, is wrapped in described current-limiting resistance 5 and pilot lamp 2 in this containment vessel 11.
For described magnetic metal body 1, can be for through magnetized iron block.
In order to make described grounding body 4 be difficult for rolling everywhere, it can be made of a metal rib piece, and is connected by flexible circuit conductor 3 between the described pilot lamp 2.
Above-mentioned electrical equipment shell leakage detector, described pilot lamp 2 is a neon tube, considers the bulk resistor of having no talent in the circuit, the selection of described current-limiting resistance 5 can be than the current-limiting resistance of common electroscope about big 2k Ω.
Embodiment two
Embodiment two is that with the difference of embodiment one embodiment two adopts the flicker diode as described pilot lamp 2, thereby further improves its warning function.
Above-mentioned electrical equipment shell leakage detector in use, can pedestal be adsorbed on electrical equipment shell surface for a long time by described magnetic metal body 1, again described grounding body 4 is positioned over ground, in case the electric leakage of electrical equipment shell, then pilot lamp 2 will be luminous, thereby cause user's vigilance, and take corresponding safety practice, and this electrical equipment shell leakage detector is simple in structure, and cost is lower, is convenient to promote the use of.
