Abstract
The invention discloses a cable detector. The cable detector includes a housing, a power supply, wiring terminals, a resistor, a potentiometer, an indicator and a diode; the wiring terminals and the indicator are arranged on a surface of the housing; the wiring terminals are connected to wiring terminal points; a positive electrode of the power supply is connected to the resistor, and then is connected to one wiring terminal, and a negative electrode of the power supply is connected to the other wiring terminal; the potentiometer, the indicator, and the diode are connected in series and then are connected to the power supply; the surface of the housing is provided with a power supply switch; and the power supply switch is positioned in a main line of a circuit. The advantages of the cable detector are that the problems of misjudgment and low work efficiency during cable detection through a universal meter can be solved, and it can be quickly determined whether a cable can reach a standard or not.
Description
Technical field
The present invention relates to power cable, particularly relate to a kind of cable detector.
Background technology
Be at present adopt digital multimeter to realize mostly to the detection of core in process of production, go measured resistance value to carry out judging whether cable core exists breakpoint or whether its quality is up to standard with the resistance gear of digital multimeter; Testing platform often because not fixing in production scene, need hand-held measurement, measure heart yearn to be connected with the test pencil of digital multimeter, often measure the actual displayed numerical value will watched on multimeter, work frequently sometimes careless, digital multimeter will be caused to come off and fall on the ground, cause instrument to damage, often there is misjudgment phenomenon, inefficiency.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of cable detector for detection streamer.
To achieve these goals, technical scheme of the present invention is: a kind of cable detector, and described cable detector comprises housing, power supply, binding post, resistance, potentiometer, indicator and diode, and surface of shell is located at by described binding post, indicator; Described binding post connects wiring end points; Be connected with one of them binding post after positive source is connected with resistance, power cathode is connected with another binding post; Described potentiometer, indicator are connected with power supply with after Diode series; Described surface of shell is provided with power switch, and described power switch is positioned on the main line of circuit.
Further, described potentiometer is provided with knob at surface of shell, arranges different gears according to cable GB resistance.
Further, described indicator comprises light emitting diode and/or hummer.
The invention has the beneficial effects as follows: solve when using multimeter detection streamer and easily judge by accident and ineffective problem, and can judge that whether cable is up to standard faster.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is circuit diagram of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
As shown in Fig. 1 Fig. 2, to achieve these goals, technical scheme of the present invention is: a kind of cable detector, and described cable detector comprises housing 1, power supply 2, binding post 3, resistance 4, potentiometer 5, indicator 6 and diode 7, and surface of shell is located at by described binding post 3, indicator 6; Described binding post 3 connects wiring end points 8; Be connected with one of them binding post after positive source is connected with resistance 4, power cathode is connected with another binding post; Described potentiometer 5, indicator 6 are connected with power supply after connecting with diode 7; Described surface of shell is provided with power switch 9; Described power switch is positioned on the main line of circuit.。
Further, described potentiometer is provided with knob 10 at surface of shell, arranges different gears according to cable GB resistance.
Further, described indicator 6 comprises light emitting diode and/or hummer.
During detection, by two nodes of two wiring end points stube cables respectively, if now light emitting diode and/or hummer do not work, namely not luminous and/or do not report to the police, then there is not breakpoint between this cable two node, otherwise then there is breakpoint in cable;
According to cable model, potentiometer is adjusted to particular gears, if light emitting diode and/or hummer work, namely luminous and/or warning, then illustrate that this cable resistance is greater than Standard, belong to defective cable; Otherwise then belong to qualified cable.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, the technology distortion that every technical scheme according to the present invention is made, and all falls within protection scope of the present invention.
