Abstract
The invention reveals a wire stock short detection circuit. A wire stock contains a wire stock interface and a plurality of connecting lines, the said wire stock interface has a plurality of wire stock pins, and one connecting line extends out from each wire stock pin correspondingly. The detection circuit includes: a testing interface in butt joint with the said wire stock interface, wherein the said testing interface has a plurality of testing pins, and the said testing pins and the said wire stock pins correspond to each other in a one-to-one manner; a plurality of testing lines which are correspondingly extended from the testing pins of the said testing interface in a one-to-one manner; a plurality of display lamps which are respectively located between the ends, which are away from the said testing interface, of the adjacent testing lines; and a power supply which is in bridge connection with the ends, which are away from the said testing interface, of the two testing lines which are on the two sides in the said plurality of testing lines. The wire stock short detection circuit can detect whether the said connection lines of the said wire stock are short or not directly and can solve the problem of time and energy consuming caused by adopting the method which detects the said wire stock pins one by one.
Description
[technical field]
The present invention relates to a kind of testing circuit, particularly relate to a kind of wire rod short-circuit detecting circuit.
[background technology]
Along with science and technology development with rapid changepl. never-ending changes and improvements, electronic product is applied in daily life more and more widely, and electronic product can need to use the connection that wire rod carries out inside or external signal conventionally.Therefore the test of wire rod is become to an important research topic.
Take FPC(flexible circuit board) be example, after welding, easily cause short circuit, also have some wire rods after high temperature, to cause its internal short-circuit, and be with the naked eye not easy to find its short circuit, when using this line, just easily occur that burning plate etc. is bad.During analytical test, need to take the measurement of multimeter one pin (pin) pin, 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 object of this invention is to provide a kind of wire rod short-circuit detecting circuit, solve the problem wasting time and energy when prior art wire rod detects.
In order to achieve the above object, wire rod short-circuit detecting circuit provided by the invention, described wire rod has wire interface and some connecting lines, has several wire rod pins on described wire interface, described in each, wire rod pin correspondence is extended a described connecting line, and this testing circuit comprises:
Test interface, it docks with described wire interface, has several test pin on this test interface, and described in each, 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 respectively adjacent p-wire away between described test interface one end;
Power supply, its be connected across in described some p-wires in both sides two away from described test interface one end between.
Optionally, described wire rod is flexible circuit board.
Optionally, described display lamp is light emitting diode.
Optionally, described power supply is also in series with switch.
Optionally, described power supply is also in series with slide rheostat.
Compared to prior art, utilize wire rod short-circuit detecting circuit of the present invention, in use, after described power connection: if display lamp is luminous described in each, described in each, each described p-wire of wire rod is normal, is not short-circuited; If exist the display lamp between two described p-wires not luminous, short circuit between two described connecting lines of the described wire rod that these two p-wires are corresponding.Thereby directly by this testing circuit, can reach whether short circuit detects to the described connecting line of described wire rod, the problem that the mode of having avoided employing to detect one by one described wire rod pin wastes time and energy.
[accompanying drawing explanation]
Fig. 1 illustrates the electrical block diagram into wire rod short-circuit detecting circuit one preferred embodiment of the present invention.
[embodiment]
Please jointly consult Fig. 1, Fig. 1 illustrates the electrical block diagram into wire rod short-circuit detecting circuit one preferred embodiment of the present invention.
In order to achieve the above object, wire rod short-circuit detecting circuit provided by the invention, described wire rod has wire interface 100 and some connecting lines 101, on described wire interface 100, there is several wire rod pins 102, described in each, wire rod pin 102 correspondences are extended a described connecting line 101, and this testing circuit comprises:
Test interface 200, it docks with described wire interface 100, has several test pin 201 on this test interface 200, and described in each, 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 respectively adjacent p-wire 202 away between described test interface 200 one end;
Power supply 400, its be connected across in described some p-wires 202 in both sides two away from described test interface 200 one end between.
Wherein, described wire rod can be flexible circuit board.Certainly, also can be applied to the detection of other wire rod short circuit.For example, through welding the wire rod that causes short circuit or cause its internal short-circuit after high temperature.
Wherein, described display lamp 300 can be light emitting diode.
Wherein, described power supply 400 can also be in series with switch 500, realizes the break-make of power supply 400 by switch 500, thereby can holding circuit.
Wherein, described power supply 400 can also be in series with slide rheostat 600, by the adjusting of slide rheostat 600, thereby can reach, the display lamp 300 of different loads size is regulated, and also can reach the protective effect to circuit on the one hand.
In use, after described power supply 400 is connected: if display lamp 300 is luminous described in each, described in each, each described p-wire 202 of wire rod is normal, is not short-circuited; If exist the display lamp 300 of 202 of two described p-wires not luminous, short circuit between two of the described wire rod of these two p-wire 202 correspondences described connecting lines 101.
Compared to prior art, utilize wire rod short-circuit detecting circuit of the present invention, thereby directly by this testing circuit, can reach whether short circuit detects to the described connecting line 101 of described wire rod, the problem that the mode of having avoided employing to detect one by one described wire rod pin 102 wastes time and energy.
