Abstract
The utility model relates to a multipurpose simple electricity testing pen which comprises a testing contact head, a neon pipe, a voltage reduction resistor and a metal spring which are connected in series and are arranged in an insulated pen sleeve, wherein the rear end of the insulated pen sleeve is provided with an insulated conducting wire connected with the voltage reduction resistor, another insulated pen sleeve is fixed to the other end of the insulated conducting wire, and a testing pen tip of the insulated conducting wire is exposed out of the insulated pen sleeve. A hand-contact electrode of the existing electricity testing pen is improved into a lengthened pen-type electrode by the insulated conducting wire, so the utility model can be used for judging whether a fire wire is electrified or not, and can accurately detect a power socket and can detect a commercial power line. The utility model has the advantages of simple structure, good safety, portability, low cost and wide test ranges.
Description
Technical field
The utility model relates to a kind of survey electric tool, specifically a kind of simple and easy test pencils of using more.
Background technology
We know that at present, existing test pencil structure is to be in series by test contact, neon tube, dropping resistor, metal spring and hand touched electrode.Test contact is contacted with measured object, staff contact hand touched electrode, when measured object has high voltage relative to the earth, the neon tube starter, the expression measured object is charged.But, detecting the dark formula socket on the wall sometimes, it is charged that common test pencil is measured live wire, can not work but plug electrical equipment, and its reason is zero line break or loose contact.General this situation of test pencil can not be used for accurately judging.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and providing can be simple in structure, safe and portable, with low cost, test specification is wide uses simple and easy test pencil more.
The technical scheme in the invention for solving the above technical problem is: a kind of simple and easy test pencils of using more, it includes test contact, neon tube, dropping resistor, metal spring, above-mentioned unit Series also is installed in the insulation pen cap, it is characterized in that: insulation pen cap rear end is provided with an insulated conductor and links to each other with dropping resistor, the insulated conductor other end is fixed with another insulation pen cap, and the test nib of insulated conductor therefrom exposes.
The hand touched electrode that the utility model will have test pencil now by insulated conductor is modified into the pen type electrode of lengthening, both can be used for judging whether live wire is charged, can detect supply socket accurately again, can also carry out the detection of line.Against existing technologies, it is simple in structure, safe and portable, with low cost, test specification is wide.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. test contact among the figure, 2. neon tube, 3. dropping resistor, 4. metal spring, 5. the insulation pen cap, 6. insulated conductor, 7. the insulation pen cap, 8. test nib.
Embodiment
As can be seen from Figure 1, a kind ofly many use simple and easy test pencil, it includes test contact 1, neon tube 2, dropping resistor 3, metal spring 4, and above-mentioned unit Series also is installed in the insulation pen cap 5, and the pen cap 5 rear portions of insulating are provided with another electrode.During use, test contact is contacted with measured object, another electrode (can be the earth) is when having high voltage relatively when measured object, and the neon tube starter represents that measured object is charged.Above-mentioned composition, structure and annexation belong to prior art, no longer further introduce.
Characteristics of the present utility model are: the insulation pen cap 5 rear ends are provided with an insulated conductor 6 and link to each other with dropping resistor 3, and the insulated conductor other end is fixed with another insulation pen cap 7, and the test nib 8 of insulated conductor therefrom exposes.The hand touched electrode that the utility model will have test pencil now by insulated conductor 7 is modified into the pen type electrode of lengthening, both can be used for judging whether live wire is charged, can detect supply socket accurately again, is used for judging live wire whether charged or zero line break or loose contact; Can also carry out the detection of line.
The utility model is simple in structure, safe and portable, with low cost, test specification is wide.
