Abstract
Multifunctional nipper pliers capable of detecting electricity can detect whether an object to be detected is electrified or not and the electricity is direct current or alternating current, are also capable of detecting polarity of the direct current, and have the screwing function of a screw driver. According to the multifunctional nipper pliers, nipper pliers head detecting metal, a circuit board and a hand touch inducing electrode are sequentially connected in an insulating shell of a handle, wherein the circuit is provided with a color-changing light emitting diode, a rectifying diode, a semiconductor, a resistor and a capacitor. A human body only needs to contact with the hand touch inducing electrode to detect whether the object to be detected is electrified or not, and detect the properties of the electricity.
Description
Technical field
Whether the utility model relates to and a kind ofly has screwdriver function and can be used for checking body to be measured charged, but especially can identify the multi-functional electrical verification nipper plier that electric current is direct current or alternating voltage and direct-current polarity.
Background technology:
At present, known nipper plier is a kind of pincerlike instrument commonly used, be mainly used to shear the thinner sub-thread of wire diameter and multi cord, and to sub-thread, the curved circle of terminal, stripping plastic insulating layer etc., can be in narrower and small working space operation, it is electrician (especially interior lines electrician), one of instrument that the assembling such as instrument and telecommunication apparatus and repair work common tool are commonly used, but also having electricity measurer and screwdriver during electric work also is its common tool, and electricity measurer commonly used is that its luminous intensity of neon tube test pencil is lower, these several instruments often are used alternatingly together, the instrument amount of carrying during so that work increases, fussy degree improves, particularly when electrician's outdoor study, be unfavorable for the simple and easy of its work and convenient, cause certain potential safety hazard.
Summary of the invention:
In order to make nipper plier have electrical verification and to distinguish the function of alternating current direct current electricity, and have the function of screwdriver, so that electrician's operation, use easylier, the required instrument that carries in the minimizing work is so that work convenient, quick and safety.But the utility model provides a kind of multi-functional electrical verification nipper plier, in the nipper plier handle, inlay the electroscopic device of a color-changing diode, utilize full-wave bridge to make three pin color-changing light-emitting diodes luminous difference when the AC/DC electricity passes through, in order to distinguish AC/DC electricity and galvanic both positive and negative polarity.For the convenient charged nipper plier head that is operated in adds a screwdriver structure, can be in some occasion alternate screwdriver work.
In the handle insulation crust, circuit board and the hand sense of touch of the sheet metal of nipper plier front end, color-changing light-emitting diode, commutation diode, semiconductor, resistance, electric capacity answer electrode to be linked in sequence, it is characterized in that: nipper plier head test metal is electrically connected with a lead-in wire of circuit board, another lead-in wire of circuit board is electrically connected with the identification induction electrode that a human body can contact, nipper plier head metal position is polished, be used for replacing screwdriver to use.
The technical scheme that its technical problem that solves the utility model adopts is: it is characterized in that: improve on the original basis of nipper plier, add electroscopic device in its insulating sleeve, nipper plier head metal position polishes, and makes it can be used for parbuckle screw; Two transistors and two resistance are connected to form a constant-current source in the circuit board, and four commutation diodes and a color-changing light-emitting diode form full-wave bridge, and a resistance and a capacitances in series are used for absorbing the crest voltage that may occur.Lead-in wire of circuit board is electrically connected with nipper plier head metal position, and another lead-in wire is electrically connected with the identification induction electrode that the human body in nipper plier handle place can contact, and is dielectric isolation layer between this lead-in wire and induction electrode and nipper plier handle metal position.
VD1-VD5 forms full-wave bridge in the electroscopic device. and wherein VD5 is the color-changing light-emitting diode of three pins.Transistor VT1, VT2 and resistance R 1, R2 form a constant-current source jointly, to guarantee providing constant electric current to light emitting diode VD5 in the wide-voltage range of being surveyed.R3 and C1 are used for absorbing the crest voltage that may occur, with protection VT1 and VT2.For guaranteeing the scope of voltage-measurable, 4 commutation diode VD1～VD4 withstand voltages should not be lower than 350v, utilize full-wave bridge to make it can distinguish the AC/DC electricity, and can distinguish galvanic polarity.If tested voltage U x is alternating voltage, then two light emitting diodes among the VD5 are all luminous, present orange; If Ux is DC voltage, then two light emitting diodes among the VD5 are different according to the polarity that voltage meets the people, can send respectively ruddiness or green glow.Nipper plier head metal position is polished, under intensity allows, can replace screwdriver to use.
The beneficial effects of the utility model are that nipper plier can verify whether body to be measured is charged charged for exchanging or direct current and direct current polarity, easy to use, simple in structure with its institute.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
