Abstract
The utility model provides a no tail-line automotive electronics test pencil, it comprises test contact, voltage stabilizing module, light emitting module, battery, hand touch electrode and shell, and test car battery or generator electricity press emitting diode and show.
Description
The utility model relates to a kind of automotive electronics test pencil.
At present, existing similar automotive electronics test pencil of the present utility model in the prior art, for example, No. 89217388.2 patents of No. 15 utility model bulletin of Chinese patent literature volume in 11 days the 6th April nineteen ninety, still, this is the automotive electronics test pencil that has only buttock line, when surveying electricity, the test pencil buttock line joins by special-purpose fishing folder and body earth, and whether the test pencil contact contacts tested electric position, normal by diode displaying voltage.
The purpose of this utility model provides a kind of no buttock line automotive electronics test pencil, when surveying electricity, need only pinch test pencil hand touched electrode by hand, and the test pencil contact contacts tested electric position, and light emitting diode can show that normally whether tested voltage site voltage in the test pencil.
The utility model is achieved in that a metallic test contact with excellent conductive performance is injection-moulded in the insulation crust with certain cavity, inserts a Voltage stabilizing module in the cavity, light emitting module and two joint button cells.Be connected to each other between metallic test contact, battery and module electrodes, and join by the hand touched electrode of spring and insulation crust afterbody, when surveying electricity, hand is pinched the hand touched electrode of test pencil, the test pencil contact contacts tested electric position, if the lumination of light emitting diode on the normal module of voltage, so otherwise the not luminous purpose of surveying electricity that reached.
Realization of the present utility model can describe in detail further combined with example structure.
Below in conjunction with accompanying drawing the utility model principle and using method are further described.
Fig. 1 is a kind of concrete structure longitudinal sectional drawing of the utility model,
Fig. 2 is the light emitting module structural drawing,
Fig. 3 is the light emitting module schematic diagram,
With reference to Fig. 1, metallic test contact 1 with excellent conductive performance and physical strength is injection-moulded in the insulation crust 2, the metallic test contact is made into the screwdriver shape, make test pencil double as screwdriver, shell 2 can be that transparent plastic is made, also can be that opaque plastic is opened a window and made, whether window is luminous in order to observe light emitting diode, shell 2 can be that pen type also can be the screwdriver shank type, shell 2 has a conical cavity, metallic test contact 1 puts in cavity at shell 2 conical tops, contact with an end of Voltage stabilizing module 3, light emitting module 5 places the rear portion of Voltage stabilizing module 3, the front end of light emitting module 5 is light emitting diodes 11, stretch out a thin copper wire 4 in the light emitting module 5, an end that passes light emitting diode 11 and Voltage stabilizing module 3 joins, copper wire 4 is input utmost points of light emitting module 5, the rear portion of light emitting module 5 is battery cases 7, the positive source 6 and the button cell 10 that stretch out in the light emitting module 5 are arranged in the battery case, the negative pole of battery case 7 double as power supplys, it and spring 9 join, and spring 9 joins with hand touched electrode 8, pen type structure hand touched electrode places on the cap for brush, and the cap for brush and insulation crust 2 usefulness spiral shells link and connect.
With reference to Fig. 2, light emitting module 5 is by light emitting diode 11, semiconductor compositing amplification tube and battery case 7 are formed, the semiconductor compositing amplification tube can be made up of two triodes, also can form by many triodes, light emitting module 5 has three extraction poles, the input utmost point 4 is drawn by the base stage of first triode of compositing amplification tube, a utmost point of collector of the positive pole of power supply and first triode (NPN) and light emitting diode joins, the emitter of the negative pole of power supply and second triode (NPN) joins, all the other each utmost points are pressed composite pipe structure and are connected, on structure, light emitting module 5 front ends are light emitting diodes 11, and the middle part is a compositing amplification tube, the rear portion is a battery case 7, uses filling insulating material around the light emitting module 5.
Principle of the present utility model and purpose are achieved in that
Hand is pinched test pencil hand touched electrode, test contact contacts with accumulator or generator positive pole, the a certain position of human body contacts with body earth, if generator or battery-operated voltage are normal, promptly this voltage is greater than voltage stabilizing diode voltage stabilizing value, then there is electric current to flow out through voltage stabilizing diode from accumulator or generator positive pole, the base stage of compositing amplification tube, emitter, human body resistance is got back to the negative pole of accumulator or generator, makes compound bassoon conducting, at this moment is connected to the light emitting diode on the compositing amplification tube, luminous by powered battery in the test pencil, otherwise light emitting diode is not luminous.
The utility model has the following advantages than the electronic test pencil for automobile of patent 89217388.2:
1, the utility model is easy to carry, the pen type structure can directly be clipped on the coat pocket, screwdriver formula structure can be put in the interior tool box of car, the electronic test pencil for automobile of patent 89217388.2 has buttock line, although buttock line can separate with a test pencil body, it is inconvenient that the interior other test pencil of clothes pocket is hidden a lead again, has just lost effect if lead has been lost test pencil.
2, the utility model is easy to use, the utility model takes out in pocket or the tool box and namely can use, hand touched electrode that hand is pinched test pencil during use, the test pencil contact contacts with tested electric position, human body a part contacts with body earth, whether can record tested voltage site voltage normal, the electronic test pencil for automobile of patent 89217388.2, must determine earlier the bonding position that the fishing folder can be clamped before surveying electricity, fishing is clipped on the bonding, again the test pencil test contact is contacted with tested electric position, could determine whether tested voltage site voltage is normal, when particularly the trouble point is many, the bonding position of necessary frequent mobile fishing folder, obviously this is inconvenient, and affects trouble shoot speed.
Claims (5)
1, a kind of automotive electronics test pencil is characterized in that it is by a plastic casing 2, test contact 1, and Voltage stabilizing module 3, light emitting module 5, battery 10, the cap for brush of spring 9 and hand touched electrode 8 or band hand touched electrode is formed.
