Abstract
The invention provides a test pencil. The test pencil comprises a test contact, a transparent insulated handle, a current-limiting resistor which is arranged on the transparent insulated handle, a neon pipe, a metal spring, a hand touch electrode, a light emitting device and a temperature sensing assembly, wherein the hand touch electrode is sequentially and electrically connected with the current-limiting resistor, the neon pipe, the metal spring and the test contact; the light emitting device comprises a battery, a switch and an LED (Light Emitting Diode) which are connected into a circuit in series; the light emitting position of the LED and a button of a the switch are arranged at the outer side of the transparent insulated handle; and the temperature sensing assembly comprises a heat conducting copper sheet and a thermometer, wherein the thermometer and a shell of the transparent insulated handle are manufactured into a whole, and a temperature sensing head of the thermometer is contacted with the test contact through the heat conducting copper sheet. The test pencil disclosed by the invention can play an illumination role in circuit test or maintenance in the dark, the temperature measurement can be simultaneously carried out while the power is tested, the working efficiency and the working safety are increased, and the test pencil has the advantages that the structure is simple, the use is convenient, safe and reliable, and the like.
Description
Technical field
The present invention relates to a kind of test pencil.
Background technology
Test pencil claims again test pencil, and it is daily electric circuit inspection testing tool commonly used.Existing test pencil does not have illumination functions, when running in the darker place of light or night, down circuitry needed rush repair, operating personnel use test pencil to operate common needs and additionally prepare an electric torch again and throw light on, and are very inconvenient, inefficiency.
In addition, existing test pencil can only be surveyed electricity and can not thermometric, and during to the circuit test of electrical equipment or circuit, the intensification that sometimes needs to survey them, and the operator touches to judge the intensification situation of electrical equipment usually after the outage with hand, such operation is both dangerous also unreliable.
Summary of the invention
The problem to be solved in the present invention provides a kind of simple in structure and when carrying out circuit test, has the test pencil of illumination and safe and reliable temp sensing function.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of test pencil comprises test contact, transparent insulation handle, is located at current-limiting resistance, neon tube, metal spring, hand touched electrode, light-emitting device and temperature measurement component on the insulated handle; The hand touched electrode is electrically connected with test contact by current-limiting resistance, neon tube, metal spring successively; Described light-emitting device comprises battery, switch and the light emitting diode that is connected into the loop; The luminous site of described light emitting diode and the button of switch are located at the outside of insulated handle;
Described temperature measurement component comprise the heat conduction copper sheet, with the shell all-in-one-piece thermometer processed of transparent insulation handle, the temperature-sensitive head of described thermometer contacts with test contact by the heat conduction copper sheet.
Preferably, be coated with fluorescent powder on the shell of described transparent insulation handle.Fluorescent powder can help the operator to find rapidly in the dark test pencil.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, test pencil plays illuminating effect in the time of can carrying out in the dark electric circuit inspection or maintenance, and survey electricity and can carry out synchronously thermometric simultaneously, the security of increasing work efficiency and working, have the advantages such as simple in structure, esy to use, safe and reliable.

Embodiment
As shown in Figure 1, a kind of Novel test pencil of the present invention comprises test contact 1, transparent insulation handle 2, is located at current-limiting resistance 3, neon tube 4, metal spring 5, hand touched electrode 6, light-emitting device and temperature measurement component on the insulated handle.
Be coated with fluorescent powder on the shell of described transparent insulation handle 2.Test contact 1 is provided with described current-limiting resistance 3, neon tube 4, metal spring 5, hand touched electrode 6 and light-emitting device by the end of plastic casting at transparent insulation handle 2 in the cavity of transparent insulation handle 2.Described hand touched electrode 6 is located at the end of transparent insulation handle 2, hand touched electrode 6 is electrically connected with test contact 1 by current-limiting resistance 3, neon tube 4, metal spring 5 successively, the shell place of the transparent insulation handle 2 of neon tube 4 correspondence positions is provided with transparent window, and is luminous in order to observe neon tube 4.
Described light-emitting device comprises battery 7, switch 8 and the light emitting diode 9 that is connected into the loop.The button of the luminous site of described light emitting diode 9 and switch 8 is located at the outside of insulated handle, and described battery 7 can be button cell, and battery 7 is installed in the transparent insulation handle 2.
Described temperature measurement component comprise heat conduction copper sheet 10, with the shell all-in-one-piece thermometer 11 processed of transparent insulation handle 2, the temperature-sensitive head 12 of described thermometer 11 is by heat conduction copper sheet 10 and test contact 1 good contact.
The course of work of this example: when carrying out circuit test with test pencil, switch on after tens seconds, can know the temperature at tested place by the number of degrees of thermometer 11 by inference.
When carrying out electric circuit inspection in the darker place of light with test pencil, press the button of switch 8, battery 7, switch 8 and light emitting diode 9 form the loop and connect, and light emitting diode 9 is luminous, and the illumination functions of test pencil is activated, thus the handled easily person operates.
Above one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
