Abstract
The utility model provides a kind of communication cable tester, comprise tester box body, toggle switch, some bulbs and some to communication cable interface group is provided with outside box body, the corresponding a pair communication interface group of each bulb, power supply and built-in resistor is provided with in box body, wherein, some bulbs are connected in parallel, each bulb by communication interface group respectively with toggle switch, built-in resistor and power sources in series.After link communication cable, the corresponding lampet of circuit general rule will light; If lampet does not work, service interruption is described; If lampet brightness is low, then illustrate that line impedance is larger.Take if wrong between core and core, just have two or more lampet and light.The quality of circuit can be judged thus.
Description
Technical field
The utility model relates to communication cable testing tool field, specifically a kind of communication cable tester.
Background technology
At the communication cable of the communication of instrument and equipment, after carrying out, before using on the machine at every turn, be always necessary to check every root core whether conducting in cable, have between core and core and do not have mistake to take.Usually, this checks that work is each and uses multimeter amount by hand, and more loaded down with trivial details, expend time in length.
Utility model content
The problem that the utility model is inconvenient to detect to solve existing communication cable, provides a kind of communication cable tester, simply can judge cable whether conducting, the situations such as between core, whether mistake is taken, and whether line impedance is normal by connecting.
The utility model comprises tester box body, toggle switch, some bulbs and some to communication cable interface group is provided with outside box body, the corresponding a pair communication interface group of each bulb, power supply and built-in resistor is provided with in box body, wherein, some bulbs are connected in parallel, each bulb by communication interface group respectively with toggle switch, built-in resistor and power sources in series.
After link communication cable, the corresponding lampet of circuit general rule will light; If lampet does not work, service interruption is described; If lampet brightness is low, then illustrate that line impedance is larger.Take if wrong between core and core, just have two or more lampet and light.The quality of circuit can be judged thus.
Further improvement, described bulb is parallel with voltage table, is provided with voltage display outside box body, and voltage table is connected with voltage display.Described each bulb is all in series with reometer, and be provided with corresponding Current Display outside box body, reometer is connected with Current Display.
By increasing reometer and voltage table, can by the detection of communication cable from the quantitative detection upgraded to according to the qualitative detection of bulb brightness according to current and voltage data, its Detection results is better, and degree of accuracy is higher, but shortcoming is the increase in cost.
Data transmission interface is provided with outside described box body.By the upper main frame of data transmission interface by data transfer, communication cable can be obtained by analysis and analyzes more accurately.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model comprises tester box body, toggle switch, some bulbs and some to communication cable interface group is provided with outside box body, the corresponding a pair communication interface group of each bulb, power supply and built-in resistor is provided with in box body, wherein, some bulbs are connected in parallel, each bulb by communication interface group respectively with toggle switch, built-in resistor and power sources in series.
After link communication cable, the corresponding lampet of circuit general rule will light; If lampet does not work, service interruption is described; If lampet brightness is low, then illustrate that line impedance is larger.Take if wrong between core and core, just have two or more lampet and light.The quality of circuit can be judged thus.
By allowing bulb shunt voltage table, the mode of series current table, improve Detection results further, can by the detection of communication cable from the quantitative detection upgraded to according to the qualitative detection of bulb brightness according to current and voltage data, its Detection results is better, degree of accuracy is higher, but shortcoming is the increase in cost.Be provided with voltage display outside box body, voltage table is connected with voltage display.Each bulb is all in series with reometer, and be provided with corresponding Current Display outside box body, reometer is connected with Current Display.
Data transmission interface is provided with outside box body.By the upper main frame of data transmission interface by data transfer, communication cable can be obtained by analysis and analyzes more accurately.
The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
