Problems solved by technology
[0002] At present, in the production process, the detection of the cable core is mostly realized by using a digital multimeter. Use the resistance gear of the digital multimeter to measure the resistance value to judge whether there is a breakpoint in the cable core or whether the quality is up to standard; The detection workbench needs to be measured by hand, and the measuring core wire should be connected with the test leads of the digital multimeter. Every time you measure one, you should watch the actual display value on the multimeter. Frequent work and sometimes careless work will cause the digital multimeter to fall off. to the ground, causing damage to the instrument, frequent misjudgment, and low work efficiency

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 [0001] The invention relates to power cables, in particular to a cable detector. Background technique [0002] At present, in the production process, the detection of the cable core is mostly realized by using a digital multimeter. Use the resistance gear of the digital multimeter to measure the resistance value to judge whether there is a breakpoint in the cable core or whether the quality is up to standard; The detection workbench needs to be measured by hand, and the measuring core wire should be connected with the test leads of the digital multimeter. Every time you measure one, you should watch the actual display value on the multimeter. Frequent work and sometimes careless work will cause the digital multimeter to fall off. If it falls to the ground, the instrument will be damaged, misjudgment often occurs, and the work efficiency is low. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a cable...
