Abstract
The utility model relates to a test pencil. The upper end of an insulating outer shell is also provided with a contact electrode which is exposed. The front surface of the insulating outer shell is provided with a digital display screen. The contact electrode is electrically connected with one end of the digital display screen, wherein, the other end of which is connected with a current-limiting resistor. Therefore, the usage is convenient, and the cost is reduced.
Description
The utility model relates to a kind of test pencil.
At present, common a kind of luminous test pencil, in the strong environment of light, on the daytime of special sunlight direct irradiation, people's naked eyes can't be seen luminous test pencil clearly and whether be in luminance; Also have a kind of digital display test pencil, in environment with dark light, night particularly, people's naked eyes can't be seen the numeral of display voltage clearly, therefore, all can use at daytime, night if desired, just must carry two kinds of test pencils, one bothers, and two change Fei Yeda.
In view of this, the purpose of this utility model provides a kind of day and night test pencil, is applicable to the daytime that light is strong simultaneously with a kind of test pencil, and is easy to use the night a little less than the suitable again light, also reduces cost simultaneously.
The purpose of this utility model is achieved in that it mainly comprises a kind of day and night test pencil, mainly be to connect the test electrode that exposes in the insulation crust lower end, and it is provided with the contact electrode that exposes by the upper end, and the insulation crust front is provided with luminous neon tube, and contact electrode connect in regular turn luminous neon tube, current-limiting resistance, resistance and test electrode, also be provided with the contact electrode that exposes at insulation crust by the upper end, be provided with digital display screen in this insulation crust front again, and contact electrode is electrically connected digital display screen one end, and this digital display screen other end connects current-limiting resistance.
Described contact electrode relatively is arranged on respectively by both sides, insulation crust upper end.
Owing to adopt such scheme: easy to use, reduce expense again.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments outside drawing.
Fig. 2 the utility model exemplary embodiments circuit theory diagrams.
Among the figure:
1, test electrode R1, resistance R 2, current-limiting resistance
2, luminous neon tube 3, contact electrode 4, contact electrode
5, digital display screen 6, insulation crust
Present embodiment comprises test electrode 1, luminous neon tube 2, contact electrode 3,4, device for digit-displaying 5 and insulation crust 6, as shown in Figure 1, and wherein:
Insulation crust 6 is a plastic casing, connects the test electrode 1 that exposes in its lower end, and this test electrode 1 is a conducting metal, and its exposed junction is " one " word screwdriver type; The front of insulation crust 6 is provided with luminous neon tube 2 and digital display screen 5 (luminous neon tube 2 and digital display screen 5 all belong to prior art products) separately; And be oppositely arranged the contact electrode 3,4 that exposes respectively in both sides near insulation crust 6 upper ends, for the hand-held contact of people.
The present embodiment circuit theory, as shown in Figure 2, contact electrode 3 connects luminous neon tube 2 one ends, and these luminous neon tube 2 other ends connect current-limiting resistance R2, resistance R 1 end to test electrode 1 in regular turn, contact electrode 4 connects digital display screens 5 one ends, and these digital display screen 5 other ends connect current-limiting resistance R2, resistance R 1 end to test electrode 1 in regular turn.
Present embodiment operation and principle thereof:
When circuit position with the test of test electrode 1 contrectation, and hand-held insulation crust 6 upper ends, if use finger contact contact electrode 3, luminous neon tube 2 can be inducing luminous, if use finger contact contact electrode 4, digital display screen 5 demonstrates voltage digital.
Claims (2)
1, a kind of day and night test pencil, mainly be to connect the test electrode (1) that exposes in insulation crust (6) lower end, and it is provided with the contact electrode (3) that exposes by the upper end, and insulation crust (6) front is provided with luminous neon tube (2), and contact electrode (3) the luminous neon tube (2) of connecting in regular turn, current-limiting resistance (R2), resistance (R1) and test electrode (1), it is characterized in that: also be provided with the contact electrode (4) that exposes by the upper end at insulation crust (6), be provided with digital display screen (5) in this insulation crust (6) front again, and contact electrode (4) is electrically connected digital display screen (5) one ends, and this digital display screen (5) other end connects current-limiting resistance (R2).
2, by the described day and night test pencil of claim 1, it is characterized in that: described contact electrode (3), (4) relatively are arranged on respectively by both sides, insulation crust (6) upper end.
