Abstract

The utility model relates to a grounding continuity test device for a plug or a socket, which comprises a plug or a socket body, and a live wire, a zero line and a ground wire which are plugged in the body, wherein, an indicator light is connected between the live wire and the ground wire. The grounding continuity test function is achieved through the indicator light connected between the live wire and the ground wire, that is, the power supply circuit is normally grounded provided the light lights up, and the power supply circuit is abnormally grounded or ungrounded provided the light doesn't light up. Therefore, the utility model can achieve the grounding continuity test function by means of the indicator light. The utility model has the characteristics of simple structure, low cost, economy and practicality, and therefore can be widely applied to the grounding continuity test for various plugs or sockets.

Description

The earth-continuity condition checkout gear of plug or socket
Technical field
The utility model relates to the ground detection device art, refers in particular to a kind of simple in structure, the economical and practical plug or the earth-continuity condition checkout gear of socket.
Background technology
At present, household electrical appliance and office appliance have spread to the every field of daily life, as refrigerator, washing machine, television set, video tape recorder, electric rice cooker, electric heater, computer, printer etc., become people work the life in indispensable capable utensil.
According to the provisions of the relevant regulations issued by the State, all shells are the electrical equipment of metal, must in these ac power plugs or socket, be provided with live wire, zero line and ground wire usually with the ac power plug and the socket of single-phase three wire system.Ground wire wherein is the part of the earth leakage protective device of electrical equipment, and it does not constitute electrical circuit, does not under normal circumstances have electric current to pass through; its end is connected on the metal shell of electrical equipment; other end ground connection, general earth terminal will go deep into more than the 1m of ground, and the metal shell of electrical equipment is connected with the earth.When electrical equipment broke down, power supply may puncture or destroy some element, made the outer casing electrification of electrical equipment, and this moment can be by the electromotive force importing the earth of ground wire with shell, and the personnel that prevent reach earth leakage protective effect because of misconnection electric shock device shell gets an electric shock.
Yet people often ignore ground wire grounded effect, though have in plug or socket, be provided with ground wire, the normal at all ground connection of this ground wire is performed practically no function, and so for the person and electrical equipment, all exists serious potential safety hazard.
The utility model content
In view of this, the utility model is at the disappearance of prior art existence, and its main purpose provides a kind of simple in structure, the economical and practical plug or the earth-continuity condition checkout gear of socket.
For achieving the above object, the utility model adopts following technical scheme:
The earth-continuity condition checkout gear of a kind of plug or socket includes the live wire, zero line and the ground wire that insert in plug or the jack body, and is connected with an indicator light that is used to detect ground wire grounded conducting state between this live wire and ground wire.
As a kind of preferred version, described indicator light is neon lamp or LED lamp, further is connected with a divider resistance between this neon lamp or LED lamp and the live wire.
After the utility model adopted technique scheme, its beneficial effect was, by being connected the measuring ability that an indicator light is grounded conducting state between live wire and the ground wire, lamp is bright to be that current supply circuit ground connection is normal, and it is that ground connection is undesired or do not have ground connection that lamp does not work.By this, use an indicator light can be grounded the measuring ability of conducting state, have simple in structurely, cost is low, and economical and practical characteristics can be widely used in the earth-continuity state-detection of various plugs or socket.
Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:
Description of drawings
Fig. 1 is the circuit theory diagrams of the embodiment of the utility model;
Fig. 2 is the vertical view of plug among the embodiment of the utility model;
Fig. 3 is the lateral perspective of Fig. 2.
Embodiment:
Please refer to Fig. 1 to shown in Figure 3, it has demonstrated the concrete structure of the preferred embodiment of the utility model, include header body 10 and insert live wire L in this body 10, zero line N and ground wire G, particularly be connected with an indicator light 20 between this live wire L and the ground wire G, utilize this indicator light 20 to detect and indicate the whether normal ground connection of current supply circuit, its operation principle is by indicator light 20 live wire L to be connected with ground wire G, make live wire L, indicator light 20, ground wire G and the earth form a complete earth-continuity state-detection loop, when ground wire G is connected just often with the earth, this earth-continuity state-detection loop has electric current to pass through, and indicator light 20 utilizes this galvanoluminescence; And when ground wire G normally was not connected with the earth, this earth-continuity state-detection loop was disconnected, and no current passes through in the loop, and indicator light 20 is not luminous.
Wherein, when this indicator light 20 adopts neon lamps and LED lamp, need be connected a divider resistance R between neon lamp and LED and the live wire L, with assurance neon lamp and the needed voltage of LED lamp, normally luminous.
Certainly, the header body 10 in the previous embodiment is not confined to the plug construction shown in the figure, and it also is suitable for appointing and closes other plug that has live wire, zero line and ground wire or socket, not to exceed.
Design focal point of the present utility model is, by being connected the measuring ability that an indicator light is grounded conducting state between live wire and the ground wire, lamp is bright to be that current supply circuit ground connection is normal, and it is that ground connection is undesired or do not have ground connection that lamp does not work.By this, use an indicator light can be grounded the measuring ability of conducting state, have simple in structurely, cost is low, and economical and practical characteristics can be widely used in the earth-continuity state-detection of various plugs or socket.
The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.

Claims (2)

1, the earth-continuity condition checkout gear of a kind of plug or socket is characterized in that: include the live wire, zero line and the ground wire that insert in plug or the jack body, and be connected with an indicator light that is used to detect ground wire grounded conducting state between this live wire and ground wire.
2, the earth-continuity condition checkout gear of plug according to claim 1 or socket is characterized in that: described indicator light is neon lamp or LED lamp, further is connected with a divider resistance between this neon lamp or LED lamp and the live wire.
