Description
Technical field
The utility model relates to a kind of electronic equipments, is specifically related to a kind of polycore cable detecting device.
Background technology
Current; Electronic technology is fast-developing, and the use of polycore cable is more and more general, extensively adopts multi-core cable wire as signal connecting line like automaton, communication engineering, network connection etc.; But the wire size of many multi-core cable wires sign is also unintelligible; Be difficult to identification, have in addition do not have a wire size, bring certain difficulty so connect to system; How fast, accurately, conveniently detect its break-make and its wire size of identification, the utility model polycore cable detecting device then changes tradition and uses the multimeter detection mode.
Summary of the invention
For reaching the foregoing invention purpose, the technical scheme that is adopted is: comprise oscillatory circuit, counting circuit, polycore cable detection terminal (P1, P2), detect pilot lamp and feed circuit; Oscillatory circuit is made up of oscillating integrated circuit chip U1 and peripheral resistor R 1, R2 capacitor C1, C2, and oscillating integrated circuit chip U1 pin 3 links to each other with counting circuit integrated chip pin 15; Be connected between oscillating integrated circuit chip U1 pin 3 and the GND after resistor R 3 and the pilot lamp LED1 series connection; The pin 3 of counting circuit chip U2, pin 4, pin 5, pin 6, pin 7, pin 8, pin 9, pin 10 connect pin 1, pin 2, pin 3, pin 4, pin 5, pin 6, pin 7, pin 8 ends that meet polycore cable detection terminal P1 behind resistor R 5, R6, R7, R8, R9, R10, R11, the R12 respectively; The pin 1 of polycore cable detection terminal P2, pin 2, pin 3, pin 4, pin 5, pin 6, pin 7, pin 8 ends link to each other with the positive pole that detects pilot lamp LED3, LED4, LED5, LED6, LED7, LED8, LED9, LED10 respectively, and its negative pole that detects pilot lamp connects the negative pole of battery E; The positive pole of battery E is connected with the pin 1 of oscillating integrated circuit chip U1 pin 4, pin 8 and counting circuit chip U2 respectively through switch S 1.
Beneficial effect: this polycore cable detecting device can detect the break-make of bunched conductor or multi-core cable wire; Can proofread the wire size at bunched conductor or polycore cable two ends; Have that volume is little, in light weight, simple to operate, easy to use, inspection quick and precisely with advantage such as low in energy consumption, can be widely used in fields such as automaton, communication engineering, network, electric meter.
Description of drawings
Accompanying drawing 1 is the polycore cable detector circuit catenation principle figure that the utility model provides.
Embodiment
Shown in accompanying drawing 1, the power supply of polycore cable detecting device whole machine using 9V layer build dry cell is after power turn-on switch S 1; Supply power to entire circuit; Power light LED2 is luminous, and oscillating integrated circuit chip U1 (NE555) begins to swing the work of shaking, and its duty is a multi-harmonic-oscillations; Dutycycle of oscillating integrated circuit chip U1 pin 3 outputs is 50% rect.p. square wave; Pilot lamp LED1 begins to glimmer luminous, and this pulse is input to counting circuit chip U2 (CD4017) pin 15, and counting circuit chip U2 this moment (CD4017) begins counting; Export high level from counting circuit chip U2 (CD4017) pin 3 successively to pin 10, deliver to pin 3 to the pin 8 of P1 port through resistor R 5 to R12 respectively; Port P1 and the middle corresponding connection polycore cable of P2, if each bar line conduction of polycore cable, then LED 3-LED10 is luminous in turn, if polycore cable has a disconnection, then corresponding with it LED lamp can be not luminous; If the connection wire size of polycore cable is not right, then the lumination of light emitting diode order is just not right, can reach in this way and detect the purpose whether multi-core cable wire is opened a way and differentiated the wire size order.
In the accompanying drawing 1, resistor adopts the carbon film device of 1/8W, wherein resistor R 1, R3:2K, R2:120K, R4-R12:1K; It is the aluminium electrolutic capacitor of 16V that capacitor adopts withstand voltage, and wherein capacitor C1, C2 are: 4.7uF; Oscillating integrated circuit chip U1 adopts NE555, and counting circuit chip U2 adopts CD4017; P1, P2 connection terminal adopt the pressure-cliping connection terminal; E adopts chargeable 9V laminated cell.
Though described the embodiment of the utility model in conjunction with accompanying drawing, the protection domain that those of ordinary skills do not need various distortion that the creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
