Abstract
The invention provides an indicator capable of rapidly determining coaxial cable BNC radio frequency head fault types. An indicating lamp, a core wire of a coaxial cable to be measured and a shielding wire are in a series-parallel relation with each other; a short circuit fault or a circuit break fault can be determined via on-off of the indicating lamp; two resistors are connected in series in a circuit, and therefore a power source can be protected when the short circuit fault occurs. One end of each of two BNC straight-in butt joints is connected with the circuit while the other end is connected with a BNC radio frequency head in testing processes; three indicating lamps are respectively used for indicating faults such as core wire and shielding layer short circuit faults, inter-core-wire circuit break faults, and inter-shielding-layer circuit break faults and the like occurring in BNC radio frequency heads at two ends of one coaxial cable. The indicator capable of rapidly determining coaxial cable BNC radio frequency head fault types is characterized by simple operation, fastness and high accuracy. Compared with a traditional universal meter, the indicator is advantaged by capability of greatly reducing test time.
Description
Technical field
The invention belongs to coaxial transmission cable technical field, be specifically related to a kind of judge coaxial cable BNC radio-frequency maser fault type indicator with replacing tradition universal meter quicklook.
Background technology
The method of traditional measurement coaxial cable BNC radio-frequency maser is the radio-frequency maser using universal meter to measure coaxial line two ends, heart yearn and screen layer, heart yearn and heart yearn, screen layer and screen layer is measured respectively with universal meter, general at least needs is measured 3-4 time, during measuring, tester must carefully hold steadily multitester probe, accidentally will make heart yearn and screen layer short circuit.If coaxial cable quantity is more, uses universal meter to measure and will form the biggest workload.
Wish to provide a kind of instruction device judging coaxial cable BNC radio-frequency maser fault type quickly and intuitively, shorten the testing time.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides the indicator of a kind of quick judgement coaxial cable BNC radio-frequency maser fault type.
The concrete technical scheme of the present invention is: the indicator of a kind of quick judgement coaxial cable BNC radio-frequency maser fault type, including radio-frequency maser contact point 1, radio-frequency maser contact point 2, also include indicator lamp 1, indicator lamp 2, indicator lamp 3, indicator lamp 4, described indicator lamp 1 and resistance R1 and resistance R2 and power supply and switch form closed loop, indicator lamp 2, indicator lamp 3, indicator lamp 4 and press button form closed loop, and described radio-frequency maser contact point 1 is connected in parallel with indicator lamp 1；When coaxial cable BNC radio-frequency maser is connected with radio-frequency maser contact point 1 and radio-frequency maser contact point 2, described indicator lamp 1, indicator lamp 2, that the bright load of indicator lamp 3 presses the button indicator lamp 4 is bright, it was demonstrated that fault-free；Indicator lamp 1, indicator lamp 2, the bright load of indicator lamp 3 press the button indicator lamp 4 again and go out, it is judged that radio-frequency maser 2 short circuit and radio-frequency maser 1 open circuit；Indicator lamp 1 goes out, it is judged that heart yearn and screen layer short circuit；Indicator lamp 2 goes out, it is judged that two ends radio-frequency maser heart yearn open circuit；Indicator lamp 3 goes out, it is judged that two ends radio-frequency maser screen layer open circuit.
According to circuit theory diagrams, power supply, resistance, indicator lamp and BNC are led directly to connector wire connect, welding, and lead directly to head by two and be fixed.During test, the BNC head at same coaxial line two ends is inserted two and leads directly to head, indicator lamp 4 be only used for indicator lamp 1,2,3 the brightest in the case of a kind of special circumstances test.Test rear indicator light is described as follows: 1, to press the button indicator lamp 4 bright for the bright load of indicator lamp 1,2,3: fault-free.The bright indicator lamp 4 that presses the button again of indicator lamp 1,2,3 goes out: radio-frequency maser 2 short circuit and radio-frequency maser 1 open circuit (pole special circumstances)；2, indicator lamp 1 goes out: heart yearn and screen layer short circuit；3, indicator lamp 2 goes out: two ends radio-frequency maser heart yearn open circuit；4, indicator lamp 3 goes out: two ends radio-frequency maser screen layer open circuit.
The invention has the beneficial effects as follows: need not universal meter, judged coaxial cable two ends BNC radio-frequency maser fault type quickly, intuitively by indicator lamp, especially in the case of the radio-frequency maser that need to measure is a fairly large number of, it is possible to be greatly shortened the testing time.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of the present invention.
Detailed description of the invention
Describe embodiments of the invention below in conjunction with the accompanying drawings in detail.
With reference to Fig. 1, a kind of indicator of quick judgement coaxial cable BNC radio-frequency maser fault type, including radio-frequency maser contact point 1, radio-frequency maser contact point 2, also include indicator lamp 1, indicator lamp 2, indicator lamp 3, indicator lamp 4, described indicator lamp 1 and resistance R1 and resistance R2 and power supply and switch form closed loop, indicator lamp 2, indicator lamp 3, indicator lamp 4 and press button form closed loop, and described radio-frequency maser contact point 1 is connected in parallel with indicator lamp 1；When coaxial cable BNC radio-frequency maser is connected with radio-frequency maser contact point 1 and radio-frequency maser contact point 2, described indicator lamp 1, indicator lamp 2, that the bright load of indicator lamp 3 presses the button indicator lamp 4 is bright, it was demonstrated that fault-free；Indicator lamp 1, indicator lamp 2, the bright load of indicator lamp 3 press the button indicator lamp 4 again and go out, it is judged that radio-frequency maser 2 short circuit and radio-frequency maser 1 open circuit；Indicator lamp 1 goes out, it is judged that heart yearn and screen layer short circuit；Indicator lamp 2 goes out, it is judged that two ends radio-frequency maser heart yearn open circuit；Indicator lamp 3 goes out, it is judged that two ends radio-frequency maser screen layer open circuit.
According to circuit theory diagrams, power supply, resistance, indicator lamp and BNC are led directly to connector wire connect, welding, and lead directly to head by two and be fixed.During test, the BNC head at same coaxial line two ends is inserted two and leads directly to head, indicator lamp 4 be only used for indicator lamp 1,2,3 the brightest in the case of a kind of special circumstances test.Test rear indicator light is described as follows: 1, to press the button indicator lamp 4 bright for the bright load of indicator lamp 1,2,3: fault-free.The bright indicator lamp 4 that presses the button again of indicator lamp 1,2,3 goes out: radio-frequency maser 2 short circuit and radio-frequency maser 1 open circuit (pole special circumstances)；2, indicator lamp 1 goes out: heart yearn and screen layer short circuit；3, indicator lamp 2 goes out: two ends radio-frequency maser heart yearn open circuit；4, indicator lamp 3 goes out: two ends radio-frequency maser screen layer open circuit.
