Disclosed is a multipurpose low voltage testing implement with acoustic-optic display, which is the upgraded product of an old testing pencil with a neon bulb. The utility model is characterized in that elements like a circuit board assembly, etc. are arranged. When power supply is switched on, small signals which are input by an AC electrical signal, a DC electrical signal and a pulse electrical signal through current limiting resistance are driven by an oscillating circuit through high-powered magnification and are provided with acoustic-optic display. In the dark, a micro switch 6 is pushed for luminous lighting. The head of the testing implement is provided with a fastening base 13 in which the rods of various small tools are optionally changeable, and the fastening base 13 can be used as a small tool for testing and repairing an electric appliance. The utility model has the advantages of multifunction, safety, and simple structure.

Description

Multipurpose low-valtage voltage testing implement with acoustooptic display

It is that a kind of low tension detects indication utensil, the examination electrical device that has acousto-optic to show when particularly serving many purposes electrical verification that the utility model relates to.

During usually existing test low tension, general generally the employing has the test pencil that neon bulb shows, test pencil is the acomia sound when electrical verification, send in the neon tube light a little less than, or make the people whether be difficult to tell the generation electricity under the high light, very easily give people's error in judgement in the open.It under the no-voltage situation break-make that can't detect lead.Especially in the dark electrical verification needs to cooperate and could use with torch and other light.And in the head position of test pencil the instrument of only fixing a kind of shape probe usually, can not adapt to the practical operation needs at any time the tool heads of replaceable other shape use as instrument.

The purpose of this utility model provides the safe and reliable one-object-many-purposes low tension test of a kind of new-type practicality and has the examination electrical device that acousto-optic shows.This examination electrical device is that the combination of utilization hyundai electronics element and other material is made, but daytime is outdoor in the open, and the situation that light the is arranged detecting electric equipment that gets off, also can in the dark illuminating lamp be opened and use, can use as electroscope, also can change the usefulness that various knife bars are made instrument according to the operational circumstances needs, direct engaged test alternating current-direct current low-voltage, the also above voltage of non-contact testing alternating current 50V closely, but break-make situations such as testing automobile lead, switch, bulb, insurance, coil, electric capacity.When voltage was arranged, when reaching line conduction, red diode was just sent red flashing signal on this examination electrical device, and piezo is sent sound, obvious sensation was arranged for the operator's vision and the sense of hearing, and is simple to operate, and safety is very reliable.

The utility model is achieved in that

Accompanying drawing 1 is the principle of work calcspar.

Having feeble signal to amplify 2 electric signal through high power as interchange, direct current, pulse signal when power supply 5 is connected through current-limiting resistance 1 input drives acousto-optics by oscillatory circuit 3 and shows that 4 carry out acousto-optic and show.Promote the miniature P cock 6 of third gear in the dark power supply 5 connection lighting bulbs 7 are just had the function of luminous lighting.

The utility model concrete structure is provided by following examples and accompanying drawing:

Accompanying drawing 2: be the utility model front schematic view.

A short and small word knife bar 8, short and small sharp cone distal knife bar 9 short and small cross knife bars 10, short and small socket bar 11, locking knife bar nut 12, knife bar Fixing clamp-seat 13 is installed, main body insulating material upper cover 14, electronic component optical diode 15, sound beep sheet 16, the miniature P cock 6 of third gear, the short probe 18 of metal.

Accompanying drawing 3: be the utility model inner member installation site figure:

Main body insulating material lower cover 19, battery 5, electronic element circuit plate assembly 20, many connecting lines 21, power contacting plate 22, upper and lower covers shell attachment screw 23.

Now the utility model is explained with regard to accompanying drawing:

The utility model is firmly to be injection-moulded in position, main body insulating material lower cover 19 termination with each shape knife bar probe of locking knife bar nut 12 usefulness threaded connection lockables by knife bar Fixing clamp-seat 13 is installed.Electronic element circuit plate assembly 20 is installed on the position in the main body insulating material lower cover 19, and an end is connected in current-limiting resistance 1, and current-limiting resistance 1 other end is welded on to be installed on the knife bar Fixing clamp-seat 13, is connected with battery 5 with the short probe of metal 18 respectively again.Battery 5 both positive and negative polarities are connected small electric bulb 7 polyphones be connected on many lines 21, be welded in respectively on the miniature P cock 6 of third gear, and other inner member small electric bulb 7, electronic element circuit plate assembly 20 is on the beep sheet 16 element positions.Again with metal probe 18, after being fixed on the position of main body insulating material lower cover 19 lead-in wire on the electronic element circuit plate 20 is welded together with the short probe 18 of metal, with third gear microswitch 6, be fixed on the main body insulating material loam cake 14 inner face positions, only expose switch and turn one's head.Beep sheet 16 also glueds joint on the inner face position of main body insulating material loam cake 14.With main body insulating material loam cake 14, be buckled together up and down with main body insulating material lower cover 19 correspondence positions and expose the optical diode 15 that is installed on the electronics main body circuit newspaper assembly 20, the back connects together main body insulating material upper and lower covers with upper and lower covers gib screw 23 and realizes that the utility model tries electrical device.

The short and small word knife bar 8 of the utility model, short and small pointed cone knife bar 9 short and small cross knife bar 10 short and small socket bar 11 locking screws 12 are installed knife bar main body Fixing clamp-seat 13, adopt the metal steel to make.

Main body insulating material upper and

lower covers

14,19 adopts ABC, plastics, bakelite insulating material to be made into, the profile geometric configuration, but rectangle, square, flat, taper, garden shape, battery 5 can be adopted small-sized common batteries No. 5, No. 4.

Using method of the present utility model is at first to choose the proper tools probe by operator's actual needs, insert back check nut 12 locking knife bars on the knife bar Fixing clamp-seat 13 are installed, the electric equipment of alternating current-direct current that detects just can directly be touched in the short probe of finger contacting metal 18 backs, lead and electrical equipment etc., the above electrical equipment of noncontact test alternating voltage 50V closely, lead and electrical equipment, can directly contact, test no-voltage lead, cable, switch, insurance, electrical equipment break-make situations such as bulb, optical diode 15 beep sheets 16 all can send red flashing signal and sound during conducting, and it is noiseless that the not conducting of opening circuit is all unglazed.Can promote the miniature P cock 6 of third gear when operating in the dark, but shift small electric bulb 7 luminous lightings on small electric bulb 7 and power supply 5 on positions onto, when electrical verification, should outside short probe 18, not provide the spreading line probe assembly 17(figure during for the higher vdct of 36～500V) test.Should not be again with human body as test access, so just can safe more electrical verification.

The utlity model has simple in structure, safe and reliable, one-object-many-purposes, small and exquisite convenience, electrical verification is accurate, fast, the operator is easy to grasp, the characteristics such as have wide range of applications can produce good economic benefits and social effect.
