Abstract
The utility model discloses a wire short circuit detection circuit. A wire is provided with a wire interface and a number of connecting wires. The wire interface is provided with a number of wire pins. A connecting wire correspondingly extends out from each wire pin. The detection circuit comprises a testing interface, a number of testing wires, a number of display lamps and a power supply. The testing interface is in butt joint with the wire interface. The testing interface is provided with a number of testing pins. The testing pins are one-to-one corresponding to the wire pins. A number of testing wires respectively extend out from the testing pins of the testing interface in a one-to-one corresponding manner. A number of display lamps are respectively arranged between ends of adjacent testing wires, which are far away from the testing interface. The power supply is in cross connection with ends of two testing wires, which are far away from the testing interface, wherein the two testing wires are located on both sides in a number of testing wires. According to the utility model, directly through the detection circuit, short circuit of the connecting wires of the wire can be detected, which avoids the problem that the time-consuming and labor-consuming mode that the wire pins are detected one by one is used.
Description
[technical field]
The utility model relates to a kind of testing circuit, particularly relates to a kind of wire rod short-circuit detecting circuit.
[background technology]
Along with the development that science and technology is maked rapid progress, electronic product is applied in the daily life more and more widely, and electronic product can need to use the connection that wire rod carries out inside or external signal usually.Therefore the test to wire rod becomes an important research project.
With the FPC(flexible circuit board) be example, through causing short circuit easily after the welding, also have some wire rods to cause its internal short-circuit, and with the naked eye be not easy to find its short circuit through behind high temperature, it is bad just to occur burning plate etc. when using this line easily.Need take the measurement of multimeter one pin (pin) pin during analytical test, waste time and energy very much.
In view of this, be necessary to develop a kind of wire rod short-circuit detecting circuit in fact, to address the above problem.
[summary of the invention]
Therefore, the purpose of this utility model provides a kind of wire rod short-circuit detecting circuit, solves the problem that wastes time and energy when the prior art wire rod detects.
In order to achieve the above object, the wire rod short-circuit detecting circuit that the utility model provides, described wire rod have wire interface and some connecting lines, have several wire rod pins on the described wire interface, each described wire rod pin correspondence is extended a described connecting line, and this testing circuit comprises:
Test interface, it docks with described wire interface, has plurality of test pins on this test interface, and each described test pin is corresponding one by one with above-mentioned wire rod pin;
Some p-wires, it is extended by the test pin of described test interface respectively correspondingly;
Several display lamps, it is located at adjacent p-wire respectively away between described test interface one end;
Power supply, its cross-over connection in described some p-wires between two of both sides are away from described test interface one end.
Optionally, described wire rod is a flexible circuit board.
Optionally, described display lamp is a light emitting diode.
Optionally, described power supply also is in series with switch.
Optionally, described power supply also is in series with slide rheostat.
Compared to prior art, utilize wire rod short-circuit detecting circuit of the present utility model, in use, behind described power connection: if each described display lamp is luminous, then the described p-wire of each bar of each described wire rod is normal, is not short-circuited; If exist the display lamp between two described p-wires not luminous, then short circuit between two of the described wire rod of these two p-wire correspondences described connecting lines.Whether short circuit detects thereby directly can reach described connecting line to described wire rod by this testing circuit, the problem of having avoided adopting the mode that detects described wire rod pin one by one to waste time and energy.
[description of drawings]
Fig. 1 illustrates the electrical block diagram into wire rod short-circuit detecting circuit one preferred embodiment of the present utility model.
[embodiment]
Please consult Fig. 1 jointly, Fig. 1 illustrates the electrical block diagram into wire rod short-circuit detecting circuit one preferred embodiment of the present utility model.
In order to achieve the above object, the wire rod short-circuit detecting circuit that the utility model provides, described wire rod has wire interface 100 and some connecting lines 101, have several wire rod pins 102 on the described wire interface 100, each described wire rod pin 102 correspondence is extended a described connecting line 101, and this testing circuit comprises:
Test interface 200, it docks with described wire interface 100, has plurality of test pins 201 on this test interface 200, and each described test pin 201 is corresponding one by one with above-mentioned wire rod pin 102;
Some p-wires 202, it is extended by the test pin 201 of described test interface 200 respectively correspondingly;
Several display lamps 300, it is located at adjacent p-wire 202 respectively away between described test interface 200 1 ends;
