Abstract
The utility model relates to a voltage detecting device, in particular to an energy storage flash type low voltage electricity measurer. The technical proposal is to install a measuring electrode whose one end extends out of the shell and whose inner end is connected in series with the contact electrode to be connected with a resistance and a neon lamp on the shell. A bridge rectification circuit whose two electrodes are connected with the neon lamp which is connected in parallel with the capacitance is installed between the resistance and the contact electrode. The inner end of the measuring electrode is connected with an elastic soldering plate which is connected with the circuit board by conductor. The shell is provided with an observing window which is a piece of unidirectional biconvex lens and a panel. The neon lamp is arranged at the place of the two convexes. The utility model provides an all sides universal electricity measurer has simple structure, needless of battery and with eye catching flash signals.
Description
Technical field
The utility model relates to a kind of voltage check device, refers in particular to a kind of energy storage flash-mode low pressure electricity measurer.
Background technology
At present, generally adopt traditional neon tube test pencil to come the through and off of metering circuit both at home and abroad, this device generally has the following disadvantages: 1, luminous faint, particularly by day or the stronger occasion of illumination, differentiating circuit has electricity still not have electricity relatively to require great effort the judgement that makes the mistake to the tester easily; 2, the potential electrode external diameter is generally at φ more than 3 millimeters, when the Flathead screwdriver edge of a knife of potential electrode end inserts socket, can only firmly believe the flat orientation of the edge of a knife, particularly there is the metal parts position in kind of the flat socket deep, the width criteria of its case surface is 2.2 millimeters, when test, some potential electrode is difficult to contact and puts in place.
Now also have and adopt acoustooptic test pencil to detect, in actual use, because have the fluctuation, self discharge, loose contact of cell voltage, in use cell voltage reduces and other condition effect such as operating environment, the indication and unreliable of making the mistake needs often to change battery in addition.
Summary of the invention
The purpose of this utility model is to design a kind of energy storage flash-mode low pressure electricity measurer, to provide a kind of simple in structure, brilliant without the flash of light of battery, signal, and can comprehensive general electricity measurer.
Its main technical schemes is to install and measure electrode on housing, and an end of potential electrode extend out to outside the housing, and resistance and neon tube successively are connected in series between the inner of potential electrode and contact electrode.
Between resistance and contact electrode, be connected bridge rectifier circuit, bridge rectifier circuit connect neon tube between two utmost points in addition, electric capacity again is connected in parallel on neon tube.
The inner in potential electrode connects the elasticity weld tabs, and the elasticity weld tabs utilizes lead to be connected with wiring board.
View window and panel are set on housing, and view window is a single face biconvex lens, and two neon tubes lay respectively at the position of two convex lens.
The outer end of potential electrode is the driver bit of 2 millimeters of φ.
The utility model has the advantages that simple in structure, do not need battery, use more convenient; Owing to be provided with lenticular mirror structure, improved the luminous intensity of neon tube, be convenient to the operator also can clearly see neon tube and sent under high light light; After having increased the passive electronic circuit, improve luminescence efficiency greatly, had general characteristics such as easy, safe and reliable.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is a circuit diagram.
Embodiment
As shown in the figure: on housing 1, install and measure electrode 4, one end of potential electrode 4 extend out to outside the housing 1, and wherein the connected mode of the inner of potential electrode 4 and contact electrode can have two kinds: a kind of is be connected in series successively between the inner of potential electrode 4 and contact electrode 2a resistance R 1 and neon tube 3a.This is a kind of common traditional metering system, and during work, signal is introduced from potential electrode 4, connect current-limiting resistance R1 through elasticity weld tabs 7, form the loop, produce potential difference (PD) by neon tube 3a, contact electrode 2a and human body, cause neon tube 3a luminous, the warning user takes care.
Another kind of mode is to be connected bridge rectifier circuit D1～4 between resistance R 2 and contact electrode 2a, connection neon tube 3a between other two utmost points of bridge rectifier circuit, and capacitor C again is connected in parallel on neon tube 3a.This mode is referred to as flash of light and surveys electric type.During work, signal is introduced from potential electrode 4 equally, connects current-limiting resistance R2 through elasticity weld tabs 7, by diode D1～4 full-wave rectifications, capacitor C, contact electrode 2b and human body form charging and discharging circuit, and it is poor to produce back lash potential, cause neon tube 3b flash of light, the warning user takes care.
The inner in potential electrode 4 connects elasticity weld tabs 7, and elasticity weld tabs 7 utilizes lead to be connected with wiring board 5.Components and parts such as bridge rectifier circuit, resistance, electric capacity and neon tube wherein are installed on the wiring board, form passive electric circuit, elasticity weld tabs 7 can improve its strength of joint and usability.
View window 6 and panel 8 are set on housing 1, and view window 6 is a single face biconvex lens, and two neon tubes lay respectively at the position of the convex lens of two disjunctors, utilizes convex lens to strengthen the luminous intensity of neon tube.So that observe the luminous situation of neon tube, panel 8 plays the inner components and parts of protection and avoids damaging.
The outer end of potential electrode 4 is the driver bit of 2 millimeters of φ.After adopting this structure, potential electrode 4 can be inserted in the jack of various supply sockets, made things convenient for operation.
