Abstract
A special-purpose test pencil for automotive electrical repair belongs to the field of a test technology. The technology scheme is provided as following: the test pencil comprises a pencil body, a test wire, a splicing fitting, a test lamp and a digital voltmeter. The lower end of the pencil body is provided with a metal test needle, the test needle and the digital voltmeter are arranged at the upper end of the pencil body, the test needle and the digital voltmeter are in parallel connection, then one end is electrically connected with the metal test needle, and the other end is electrically connected with the splicing fitting through the test wire. According to the utility model, the digital voltmeter is additionally provided based on the traditional electric test lamp, the voltage of the test circuit can be measured when the test circuit is on/off, and convenient conditions are provided for correct diagnosis of a fault. The volume of the test pencil is small, the special-purpose test pencil is portable, and the special-purpose test pencil is specially suitable for the automotive electrical maintenance personnel to use.
Description
Technical field
The utility model relates to and a kind ofly using when auto electrical services, is used for judging the device of power circuit break-make, belongs to technical field of measurement and test.
Background technology
When vehicle is carried out electrical repair, usually need to judge whether wire or connection terminal are communicated with power supply, because the multimeter volume is larger, carry inconvenience and be unsuitable for on-the-spot use of the higher vehicle maintenance of narrow space, operating position, so auto repair personnel normal operation examination electricity examination lamp comes the break-make of measurement circuit.Examination electricity examination lamp be two ends with the autobulb of wire, with the wire bonding of autobulb one end, the wire of the other end is connected with tested wire or terminal during test, just can judge the break-make of circuit by the light on and off of observation bulb.Although this testing tool is easy to carry, the break-make of estimation of line roughly, and can not judge whether line voltage distribution is normal, and bring difficulty for the Accurate Diagnosis of fault, therefore be necessary to be improved.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of volume small and exquisite, easy to carry, namely can judge the break-make of circuit, the special-purpose test pencil of auto electrical services that again can measuring circuit voltage.
Problem described in the utility model is realized by following technical scheme:
The special-purpose test pencil of a kind of auto electrical services, comprise handwriting, p-wire, binding clip, examination lamp and digital voltmeter in the formation, the lower end of described handwriting is provided with the metal test point, described examination lamp and digital voltmeter are installed in the handwriting upper end, an end was electrically connected with the metal test point after the two was connected in parallel, and the other end after tested line is electrically connected with binding clip.
The special-purpose test pencil of above-mentioned auto electrical services, described examination lamp adopts autobulb or light emitting diode.
The utility model has been set up digital voltmeter on the basis of tradition examination electricity examination lamp, and the voltage of all right measuring circuit in the measurement circuit break-make is for convenience has been created in the correct diagnosis of fault.This test pencil volume is small and exquisite, easy to carry, is particularly suitable for the auto electrical services librarian use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is electrical schematic diagram.
Each label is among the figure: 1, binding clip; 2, p-wire; 3, handwriting; 4, metal test point; V, digital voltmeter; L, examination lamp.
Embodiment
Referring to Fig. 1, Fig. 2, the utility model is comprised of binding clip 1, p-wire 2, handwriting 3, metal test point 4, digital voltage Table V, examination lamp L, metal test point 4 coaxial handwriting 3 lower ends that are embedded in, its upper end wire by running through handwriting 3 and digital voltage Table V be connected lamp L and be connected, the digital voltage Table V is passed through p-wire 2 with the other end that is connected lamp L and is connected with binding clip 1.
Using method: when testing certain wire or terminal and whether being communicated with power supply, binding clip 1 is clipped in the bare metal position of vehicle frame, and the operator hands handwriting 3, makes metal test point 4 and tested wire or termination contact, if examination lamp L does not work, illustrate between tested wire or terminal and the power supply and open circuit; If examination lamp L lights, illustrate that tested wire or terminal are communicated with power supply.Read the registration of digital voltage Table V in the measuring process, can learn the voltage between tested wire or terminal and the vehicle frame, if voltage is normal, illustrate that the circuit contact is good, if voltage is lower than normal value, illustrate that circuit loose contact or supply voltage are undesired, should further check.
Claims (2)
1. the special-purpose test pencil of auto electrical services, it is characterized in that, comprise handwriting (3), p-wire (2), binding clip (1), examination lamp (L) and digital voltmeter (V) in the formation, the lower end of described handwriting (3) is provided with metal test point (4), described examination lamp (L) and digital voltmeter (V) are installed in handwriting (3) upper end, an end was electrically connected with metal test point (4) after the two was connected in parallel, and the other end after tested line (2) is electrically connected with binding clip (1).
