Abstract

The utility model relates to a plug capable of testing socket perfectness. A resistor and a light-emitting diode (abbreviation is LED) are connected in series with the plug in sequence with the positive electrode end of the plug which is integral forming. The tail end of the plug is connected with the negative electrode end. So the plug is formed and is inserted in a power socket. When the positive electrode end and the negative electrode end of the plug contact a conductive reer to form a passage, the LED are luminous. On the contrary, the passage can not be formed, because the conductive reer of the power socket gets loose or a socket can not supply power source. So the purposes of fast detecting whether the socket is undamaged and fast detecting the effect of efficiency property can be achieved.

Description

The plug of tool test socket integrity

The utility model relates to attaching plug, refers to a kind of attaching plug of tool test socket integrity especially.

" plug " is indispensable in the modern civilization electrification articles for use, for making the power supply supplying media of its performance function, also is very common well known product also.Yet, when general electrical equipment is inserted in plug in use in the socket aperture of supply socket, can take place occasionally plug to be finished to be inserted in the supply socket, but the awkward situation that the electrical appliance that desire is used still can't be switched on and be opened, especially with under the situation of not having any testing tool on hand, ignorant sense at a loss what to do is arranged more.

And, generally look like the generation of this kind situation, nothing more than being conductive reed and the positive and negative extreme loose contact of plug in the supply socket, or the power line stamen in the supply socket is damaged or loose contact due to.

In view of this, creator of the present utility model is promptly redesigned improvement at the desirable not to the utmost place of above-mentioned known plugs, and then reach the fast detecting supply socket convenience expection the effect whether intact place that reaches obvious indication plug is located, and the utility model that has novelty, progress and practicality concurrently that gets.

But whether main purpose of the present utility model is to get loose at the conductive reed that a kind of fast detecting supply socket is provided, and, whether the socket power supply is normal, and obviously indicates the place, place of plug, and can improve the plug of the novel structure of electrical safety and tool orientation sign function.

In order to achieve the above object, its positive electricity end that is inserted in supply socket live wire end with plug of the utility model is positioned at non-exposed section and establishes with a resistance and a light emitting diode string in regular turn, and its line end is extremely linked with negative electricity, constitute a regional loop with this, and when being plugged at supply socket with two electrode tips by the plug of above-mentioned formation, if establish in its two electrode tip and the above-mentioned supply socket to press from both sides and pull that conductive reed makes contact to path or the power supply of supply socket own is provided with intact person, then above-mentioned light-emitting diode can be path shinny because of detecting the loop, otherwise, if do not make contact to path or power supply is connected with imperfect, then be the state of not working, can directly detect integrity of informing supply socket and the fail safe that ensures electricity consumption, whether thereby reaching the conductive reed that detects supply socket gets loose, and, whether the socket power supply is normal, and obviously indicates the place, place of plug, and can improve the function of electrical safety and tool orientation sign.

To the utility model further understanding can be arranged for making, below lift a preferred embodiment now, conjunction with figs. is described in detail as follows constitution content of the present utility model and the effect reached thereof:

Fig. 1 is a stereo appearance figure of the present utility model.

Fig. 2 is a cross section view of the present utility model.

Fig. 3 is an electric wiring plan of the present utility model.

Fig. 4 is inserted in the enforcement reference diagram of supply socket for the utility model.

Fig. 5 is a partial sectional view as shown in Figure 4.

See also shown in Figure 1, the plug of the utility model tool test socket integrity, it is in the making flow process of plug 1, shown in Figure 2 with cutaway view as Fig. 1, the positive electricity end 11 that is inserted in supply socket 2 live wire ends in two electrode tips with plug 1 is connected with a resistance 13 and a light-emitting diode 14 in regular turn, and its line end and negative electricity extreme 12 are linked, form as shown in Figure 3 a regional loop with this, afterwards, again by two electrode tips 11 and 12 respectively with the electrification articles for use be connected with the supply electric wire extended line 3 two coat heart stamens wherein one be connected, give one-body molded coating again and promptly constitute plug 1 structure of the present utility model.

Consult Fig. 4, Fig. 5, when plug 1 of the present utility model is inserted in the supply socket 2, after the plug 1 of this formation was in being plugged in supply socket, its positive and negative electrode end 11,12 contacted with the conductive reed 21 of supply socket 2 when forming path, and 14 of this light-emitting diodes present shinny state; Otherwise, if fail to form path, the state that gets loose that then very likely has been external-open, or the power supply line end of socket 2 damages and be unable to supply due to the power supply for the conductive reed 21 of supply socket 2, and can be as the effect that whether easy, fast detecting socket intact and the tool detection efficiency is high.With electrification articles for use fail safe in use in guaranteeing to live.

In sum, the plug of the utility model tool test socket integrity, for but whether a kind of conductive reed of fast detecting supply socket gets loose, and, whether the socket power supply is normal, and obviously indicate the place, place of plug, and can improve the novel plug construction of electrical safety and tool orientation sign function.And its formation structure be not seen in again in books and periodicals or public use, should meet the utility application condition, so propose utility application in accordance with the law.

Need to prove, the above is specific embodiment of the utility model and the know-why used, if the equivalence of doing according to conception of the present utility model changes, when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, all should be in the technical solution of the utility model scope.

Claims

1, a kind of plug of tool test socket integrity, it is characterized in that: the wherein end that plug two electrode tips are positioned at non-exposed section is established with resistance and light emitting diode string in regular turn and is connected, and make its another connect elongated end and be connected with and form one in another electrode tip with this and detect the loop.

2, the plug of tool test socket integrity according to claim 1 is characterized in that: described to establish the initiating terminal that is connected with resistance and light emitting diode string be positive electricity end.
