CN201673198U - Test pencil with illumination function - Google Patents

Abstract

The utility model relates to an electrician tool, in particular to a test pencil. The test pencil with the illumination function comprises a test contact, a circuit unit, a touch electrode, an insulating rod, a concave groove on the insulating rod, a flashlight wall, a lamp bulb, a battery, an illuminating line and a flashlight switch. The test contact, the insulating rod and the flashlight wall are connected sequentially, i.e. the test contact and the flashlight wall are respectively on both sides of the insulating rod. The flashlight wall is in threaded connection with the concave groove on the insulating rod. The test pencil not only can make a detection operator easily find the detected position in the detecting process, but also can reduce the amount of tools which must be carried by the operator and can be also used as an emergency tool for the operator in the dark.

Description

A kind of test pencil that carries illumination

Technical field

The utility model relates to a kind of electrician's instrument, particularly a kind of test pencil.

Background technology

Whether test pencil is a kind of electrician's instrument, be used in the test wires charged.At present, traditional test pencil is by a neon bulb being arranged in its handwriting, if neon bulb is luminous during test, illustrates that lead has electricity, perhaps is the live wire of path; Otherwise the lead no power then is described, perhaps is the zero line in the path.But because the brightness of neon bulb is less, and only just can be luminous when charged in measuring circuit, this makes troubles just for the operating personnel of detection line in the darker condition of light, and has also buried potential safety hazard.

Summary of the invention

The purpose of this utility model provides a kind of illumination test pencil that carries, and makes the operating personnel can the safe, efficient measuring junction that finds under the darker situation of light, and circuit is simple, and is easy to use, safe and reliable, the detection efficiency height.

A kind of test pencil that carries illumination, comprise test contact, circuit unit, hand touched electrode, insulating bar, this test pencil that carries illumination also comprises Baltimore groove, torch barrel, bulb, battery, illuminating line, the flashlight switch on the insulating bar, test contact, insulating bar, torch barrel are linked in sequence, test contact and torch barrel are connected to the insulating bar both sides, and the torch barrel is connected in the Baltimore groove on the insulating bar by being threaded.

This carries the test pencil of illumination, not only makes the operating personnel of detection can find the detection position easily when detecting, and has also reduced the number of tools that the testing staff must carry.Also can be used as simultaneously the emergent in the dark instrument of user of service.

Embodiment

As shown in Figure 1.Test contact and torch barrel are connected to the both sides of insulating bar, and the torch barrel is connected in the Baltimore groove on the insulating bar by being threaded.During testing power supply, the part of human body contact hand touched electrode position is got final product, its effect is identical with traditional test pencil.One section of torch barrel in the time need throwing light in the darker place of light, just can be opened flashlight switch, opens bulb, plays the effect of illumination.

Although the utility model here specifically describes in conjunction with the specific embodiments, but be understandable that this is illustration rather than restriction, under the prerequisite of the spirit of the present invention that does not break away from accessory claim and limited, in the scope of and accompanying drawing disclosed at preamble, it all is possible reasonably changing and revising.

Claims (1)

1. test pencil that carries illumination, comprise test contact, circuit unit, hand touched electrode, insulating bar, it is characterized in that: this test pencil that carries illumination also comprises Baltimore groove, torch barrel, bulb, battery, illuminating line, the flashlight switch on the insulating bar, test contact, insulating bar, torch barrel are linked in sequence, test contact and torch barrel are connected to the insulating bar both sides, and the torch barrel is connected in the Baltimore groove on the insulating bar by being threaded.
