Abstract

The utility model relates to the ground connecting wire device of the eye protecting glasses of a computer or a TV, which can detect the positive electricity or negative electricity. One side of the joint body of a single-leg plug arranged in front of a ground connecting wire is provided with a metal plate. The space between the plug and the metal plate is cascaded with a resistor and a neon lamp. Thus the correct position of a ground wire hole can be immediately and synchronously detected when the plug of the joint body is inserted into a socket. Thus the ground connecting wire of the eye protecting glasses of the TV and the computer can be directly, rapidly and correctly inserted into the ground wire hole of the socket. The eye protecting glasses can eliminate the low-frequency and the static electricity which are harmful to the human body. The use and the operation are simple and the effect is ideal.

Description

Can detect plus-minus electric teleputer goggles grounding wire device

The utility model belongs to the circuit jockey, relates in particular to a kind of plus-minus electric teleputer goggles grounding wire device of detecting.

The general human injury of teleputer in order to prevent that low frequency radiation or static from causing, all before the teleputer screen, add a goggles or net 1, the lead 2 that utilizes mirror or wire side to extend, harmful low frequency or static are conducted to the ground eliminating, modal this traditional product as shown in Figure 1, be to utilize the joint body 3 of the plug 31 that lead 2 front ends are provided with to insert the ground terminal (not shown) of sockets, the operator will differentiate the position whether correct (ground wire hole) of inserting socket, generally must be equipped with a voltage test pencil 4 in addition, as shown in Figure 2, these voltage test pencil 4 front ends are provided with driver bit 41, the other end is provided with metallic conductor 43, and in its grip, be provided with resistance (not shown) and neon lamp 42, the finger touches metallic conductor 43 of personnel selection, again driver bit 41 is inserted in the socket, if insertion end will cause leaky for the live wire hole, neon lamp 42 is lighted, if 42 of this neon lamps of ground wire hole can be not shinny, the effect of resistance is the electric current that the restriction human body can bear, when goggles or net 1 are inserted in that joint body 3 on the socket is touched down or when pulling off, need to insert once more again, at this moment test with voltage test pencil again, very loaded down with trivial details and the trouble, if do not whip joint body 3 is inserted in any jack because of wanting to take the trouble, in case be inserted in the live wire hole, will make goggles or net 1 that electric conduction phenomena takes place, at this moment, not only goggles or net do not have gets rid of the harmful low frequency radiation and the function of static, also can give to manipulate and bring danger.

The purpose of this utility model is to provide a kind of plus-minus electric teleputer goggles grounding wire device of detecting, it is simple in structure, and joint body can be detected positive negative electricity in inserting socket aperture the time synchronously, reach correct plug wire purpose fast, thereby overcome the defective of traditional product.

The utility model adopts following technical scheme:

The utility model can be detected plus-minus electric teleputer goggles grounding wire device, comprise that the joint body and the front end thereof that connect ground wire are provided with the plug that plugs the socket hole, the joint body side is provided with for the metallic plate that touches of finger, its with plug between be connected in series a resistance and a neon lamp.

The utility model can be detected plus-minus electric teleputer goggles grounding wire device, the metallic plate that the confession finger that is provided with by the joint body side touches, and and plug between the project organization of series resistor and neon lamp, make when inserting socket live wire end, finger touches the metallic plate place of joint body, make neon lamp shinny, remind the user to know that the socket aperture of insertion is the live wire hole, and need joint body is plugged to another socket hole, when inserting the ground wire hole, finger touches metallic plate, and neon lamp can be not shinny, the correct position that inserts is described, thereby reaches direct, fast, correct plug wire purpose.

Specifically narrate embodiment below in conjunction with accompanying drawing:

Fig. 1 is the planar structure schematic diagram of traditional product

Fig. 2 is the perspective view of traditional voltage test pencil

Fig. 3 is a perspective view of the present utility model

Fig. 4 is a cross-sectional view of the present utility model

Fig. 5 is an application state schematic diagram of the present utility model

Consult Fig. 3; 4; shown in 5; the utility model can be detected plus-minus electric teleputer goggles grounding wire device; comprise the set joint body 5 of lead 2 ends that connects ground wire; and side be provided with for the metallic plate 7 that touches of finger; 6 of the plugs that itself and joint body 5 the place aheads confession socket 9 holes plug; be connected in series a resistance 8 and a neon lamp 80; resistance 8 is one provides human body to bear the protection structure that electric current passes through; the one end is connected with metallic plate 7; the other end is connected with neon lamp 80; neon lamp 80 is connected with plug 6 by other end; when inserting the live wire end of socket 9 (not shown); finger touches metallic plate 7 places of joint body 5; can make electric current through neon lamp 80 to resistance 8; import ground through metallic plate 7 to human body again and become a path; make neon lamp 80 shinny; the user will know that socket 9 holes of insertion are the live wire hole like this; should plug header body 5 to another socket 9 holes this moment; because the hole of changing is the ground wire hole; so finger touches metallic plate 7; neon lamp 90 can be not shinny yet, i.e. the correct position of plug 6 insertions of joint body 5.

In sum, the utility model can be detected plus-minus electric teleputer goggles grounding wire device, and scientific structure design, rationally and simple, easy to use, safe and reliable overcomes the defective of traditional product, reaches design purpose.

Claims

1, a kind ofly detects plus-minus electric teleputer goggles grounding wire device, comprise that the joint body and the front end thereof that connect ground wire are provided with the plug that plugs the socket hole, it is characterized in that, described joint body side is provided with for the metallic plate that touches of finger, its with plug between be connected in series a resistance and a neon lamp.
