In the insulative casing of the main neon- electroscope body, a testing contact head, a main neon- electroscope body spring, a current limiting resistant, a neon tube and a hand- touching electrode are in series connection, wherein, a socket is added on the top and connected with the main neon- electroscope body spring. In the insulative casing of the auxiliary neon- electroscope body, two paralleled branches are arranged, wherein, the first branches includes an auxiliary neon- electroscope body contact head, an auxiliary neon- electroscope body spring, a bulb, a change- over switch, an auxiliary neon- electroscope body socket; the second branch includes an auxiliary neon- electroscope body contact head, an auxiliary neon- electroscope body spring, a battery, an ultraviolet lamp, a music integrated block rheomicrophone, a change- over switch, an auxiliary neon- electroscope body socket. The auxiliary neon- electroscope body socket and the main neon- electroscope body socket are in series connection through a plug and a lead. The main neon- electroscope body is used to test if the tested object is charged. If the main and auxiliary neon- electroscope body plugs are inserted and the change- over switch is switched, the utility model can be used to test the switching state of the lead and the electric quantity of the dry battery of 1.5- 3V. If the two button switches are pressed respectively, then the utility model can be used for lighting and detecting bank note.

Description

Five use test pencil

Affiliated technical field

The utility model relates to a kind of instructed voltage existence, conductor on off operating mode, currency examine, illumination and shows that 1.5V---five of 3V dry cell electric weight is used test pencil.

Background technology

Present test pencil is to be in series by test contact, current-limiting resistance, neon tube or display screen, metal spring, hand touched electrode etc., and the circuit relative complex lacks the function of the most frequently used measurement dry cell electric weight again in the function.

Summary of the invention

In order to overcome the deficiency of existing test pencil, the utility model provides a kind of five to use test pencil, but this electroprobe not only instructed voltage exist but also can indicate conductor on off operating mode, currency examine, illumination, especially can discern 1.5V---what of 3V dry cell electric weight, and simple in structure.

The technical scheme that its technical matters that solves the utility model adopts is: a chief editor, a secondary pen are set, in chief editor's insulation crust, chief editor's contact, chief editor's spring, current-limiting resistance, neon tube, hand touched electrode are electrically connected in proper order, the top is provided with a socket, and socket is connected with chief editor's contact is inner; In the insulation crust of secondary pen two parallel branches are set, switch by single-pole double-throw switch (SPDT) between two parallel branches, first branch road is: secondary style of writing head, a secondary spring, bulb, switch, secondary pen socket, above components and parts are electrically connected in proper order.Second branch road is: secondary style of writing head, a secondary spring, battery, uviol lamp, switch, secondary pen socket, above components and parts are electrically connected in proper order.In addition, with bulb one termination anode, the other end connects battery cathode by push switch, and when pressing push switch, battery is given bulb powered, is used for throwing light on; With uviol lamp one termination battery cathode, an end connects anode by push switch, presses push switch, and battery is powered to uviol lamp, is used for currency examine, and illumination and currency examine light are by two longitudinal 2 observation windows at a pair top.Again chief editor's socket and secondary pen socket are connected by chief editor's plug, outer lead, secondary penholder head.All components and parts of major and minor electroprobe are put into the drawer type element of insulation earlier and are located the cavity of putting into chief editor, secondary pen after locate in the storehouse again, and screw on outside screw and handwriting are fixed.

When whether the test measured object is charged, only use the chief editor, and pull up chief editor's plug at chief editor top, chief editor's contact contact testee, the electrode screw of staff contact chief editor side when the neon tube starter, represents that measured object is charged.

When the on off operating mode of tested conductor, with chief editor's plug, secondary penholder head inserts respectively in chief editor's socket and the secondary pen socket, make the chief editor, secondary pen series connection, stir switch, connect second branch road, if conductor conducting, anode in the then secondary pen is by a secondary spring, secondary style of writing head, measured conductor, chief editor's contact, chief editor's spring, chief editor's socket, chief editor's plug, external wire, secondary penholder head, secondary pen socket, switch, uviol lamp or audio manifold block microphone, make it obtain normal power supply and luminous or sounding, if the luminous or microphone sounding of uviol lamp, the conducting of expression conductor, otherwise expression conductor " open circuit ".

When testing 1.5V---how many times of 3V dry cell electric weight, with chief editor's plug, secondary penholder head inserts respectively in chief editor's socket and the secondary pen socket, and stir switch, connect first branch road, if tested battery has, then tested battery is by chief editor's contact, chief editor's spring, chief editor's socket, chief editor's plug, external wire, secondary penholder head, secondary pen socket, switch, bulb, a secondary spring, secondary style of writing head, tested battery, it is gone into current supply circuit, give bulb powered in the secondary pen and luminous, and luminosity is different with the height of tested cell voltage, utilize comparison or experience to be judged, at this moment, should cover vertical window to increase the light and shade contrast, observe from the horizontal window that connects with finger.

When illumination, press push switch, make battery cathode pass through push switch and directly give bulb powered, make its luminous lighting.

When currency examine, press another push switch, battery is powered to uviol lamp by push switch, make its luminous currency examine.The beneficial effects of the utility model are: but but this test pencil not only instructed voltage have but also can indicate on off operating mode, while currency examine, the illumination of conductor and show 1.5V---3V dry cell electric weight how much.Only increase a secondary pen and a small amount of components and parts on the cost, do not need complicated circuit and apparent letter stencil, have simple in structure, the characteristics that the little cost of volume is low.
