Abstract
The utility model provides a test pencil with multiple neon lamps. The test pencil is characterized in that the test pencil is provided with a plurality of sets of neon lamps and resistors. The neon lamps and resistors in each set are connected in series, and each set of neon lamps and resistors is connected in parallel. Compared with ordinary test pencils, the test pencil with multiple neon lamps provided by the utility model can prevent incorrect testing due to the damage of the neon lamps to generate unexpected accidents, such as electric shock, etc., and thus the reliability of the test pencils and the safety degree of operation are increased.
Description
The utility model is relevant with electrician's test pencil, and a kind of improved electrician's test pencil promptly is provided.
Has only a neon lamp in the test pencil that the electrician generally adopts at present, its shortcoming be if neon lamp in case damage then cause survey show malfunctioning, the electrician shows according to the survey of mistake that the result operates then can cause many accidents that should not take place, not only can cause the damage of equipment, and can cause personal injury and other unexpected calamity such as fire, blast or the like direct or indirect accident.
The purpose of this utility model is that the higher test pencil of a kind of reliability of design is to improve the safe coefficient of electrician's operation.
Many neon lamps test pencil provided by the utility model includes parts such as a body, nib, neon lamp, resistance and spring, it is characterized in that having the combination of many cover neon lamps and resistance, comprises a neon lamp and a resistance in the combination of every cover neon lamp and resistance.Neon lamp and resistance adopt and are connected in series within every cover combination, adopt between the combination of every cover neon lamp and resistance to be connected in parallel.
An embodiment of many neon lamps test pencil provided by the utility model as shown in Figure 1 and Figure 2, Fig. 1 is its front elevation, Fig. 2 is its side view.Parts among the figure are: neon lamp (1), resistance (2), spring (3), nib (4).
As can be seen from Figure 1, include two neon lamps in this test pencil, two neon lamps are connected in series with resistance respectively, two cover neon lamps and resistance adopt after the tandem compound, adopt between every cover combination again and be connected in parallel: an end of two resistance links together as shown in FIG., and the metal nib of reconciliation taper is connected.The terminals that two neon lamps discord resistance links to each other are attached on the same contact screw by spring, this screw when survey is shown by the hand touch that holds a pen it.
Though this embodiment adopts the pen type contour structures, this does not mean and is only limited to this contour structures, as making mini pistol formula contour structures and other contour structures yet.Can adopt installation arranged side by side between the neon lamp, also can adopt serial connection to install.If the pistol type contour structures still can be placed standby neon lamp in rifle.
Many neon lamps test pencil provided by the utility model is compared with in the market common single neon lamp test pencil, can as usual survey when the part neon lamp is damaged and show work. Also can in time find and in time change for the neon lamp that has damaged, can say fundamentally to have eliminated owing to neon lamp damages the survey that causes and show mistake. Thereby can avoid owing to surveying the device damage show mistake and to cause, personal injury etc. directly or accident indirectly. The reliability of test pencil and the safe coefficient of work like this, have just greatly been improved.
Claims (2)
1, a kind of many neon lamps test pencil that is used for electrical measuring, it includes parts such as a body, nib, neon lamp, resistance and spring, it is characterized in that having the combination of many cover neon lamps and resistance, comprises a neon lamp and a resistance in the combination of every cover neon lamp and resistance.
By the described many neon lamps test pencil of claim 1, it is characterized in that in the combination of said every cover neon lamp and resistance that 2, neon lamp and resistance adopt and is connected in series, and are connected in parallel and adopt between the combination of every cover neon lamp and resistance.
