Abstract

The invention relates to a simple cable testing instrument comprising a universal meter, two eight-sheet terminal bars, and two RJ45 interfaces. A gear of the universal meter is stirred to a diode measurement gear; eight groups of corresponding terminals of one eight-sheet terminal bar are connected in parallel by connecting wires and then are connected to one RJ45 interface; the other eight-sheet terminal bar is connected to the other RJ 45 interface; a cable having two ends with RJ45 plugs is inserted into the two RJ45 interfaces; and the positive electrode expressed by "+" and the negative electrode marked by "-" of the universal meter are connected to any two ports of the eight-sheet terminal bar that is not connected in parallel by connecting wires. Compared with the prior art, testing time of a cable is shortened; a practical problem that a cable can not be measured because of lack of a cable testing instrument can be solved; and the precious time for equipment debugging and running recovery is bought. The provided simple cable testing instrument can be manufactured simply; available elements can be used fully; the manufacturing time is short; and the practical application is effective.

Description

A kind of simple and easy network cable tester
Technical field
The present invention relates to a kind of weak electric test device, be specifically related to a kind of simple and easy network cable tester utilizing circuit tester and terminal block, RJ45 interface to make.
Background technology
Current newly built and improved transformer station mostly is intelligent substation, and being connected and communicate with between equipment adopts netting twine more, and netting twine mainly uses twisted-pair feeder.Twisted-pair feeder have employed the plain conductor of a pair mutual insulating mode stranded mutually to resist a part of external electromagnetic wave interference.The copper conductor thoroughly doing away with edge two twists mutually together by certain density, it is possible to reduce the degree of signal disturbing, and the electric wave that each wire radiates in the transmission can be offset by the electric wave sent on another single line.The name of " twisted-pair feeder " is also come therefrom.Twisted-pair feeder is generally entwined mutually by two 22-26 insulated copper wire, and time actually used, twisted-pair feeder is wrapped in an insulated cable sleeve pipe together by multipair twisted-pair feeder.Typical twisted-pair feeder is four pairs.
After twisted-pair production is good, by needing the special network cable tester of use to carry out whether test netting twine turns on.But in substation field work process, there is nonbursty network data interruption and do not carry the situation of network tester at one's side, at this moment, the circuit tester inside the workbox carried and terminal block, RJ45 interface is how used to make simple network cable tester, carry out the test of netting twine, get rid of the network failure owing to netting twine interruption causes, be technical problem urgently to be resolved hurrily.
Summary of the invention
For solving in substation field work process, there is nonbursty network data interruption and do not carry the situation of network tester at one's side, the circuit tester inside the workbox carried and terminal block, RJ45 interface is how used to make simple network cable tester, carry out the test of netting twine, get rid of owing to netting twine interrupts the technical problem of the network failure caused, the invention discloses a kind of simple and easy network cable tester, take technical scheme be:
A kind of simple and easy network cable tester, it is characterized in that: by one piece of circuit tester, two 8 terminal block and two RJ45 interface compositions, the gear of described circuit tester is allocated to diode measurement gear, 8 groups of corresponding terminals of one of them 8 terminal block are parallel to together by connecting line and are connected on a RJ45 interface, another 8 terminal block are connected on a RJ45 interface, two ends are inserted on two RJ45 interfaces with the netting twine of RJ45 connector, circuit tester "+" and " " pole be respectively connected to not pass through on any two port of connecting line those 8 terminal block in parallel.
Further, eight independent cores inside described netting twine are divided into 4 groups, every both threads Lu Weiyi group, respectively to often organize circuit carry out circuit break-make measure, when circuit tester sends buzzer sound, represent this group circuit no problem, otherwise existing problems.
Compared with prior art, the present invention shortens the testing time of netting twine, reducing because lacking the practical difficulty that cannot measure netting twine that network cable tester causes, striving for valuable time for equipment debugging with resuming operation.Simple and easy network cable tester makes relatively easy, it is possible to making full use of the element being easily obtained, Production Time is short, practical application is effective.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the present invention.
Detailed description of the invention
Referring to Fig. 1, a kind of simple and easy network cable tester, by one piece of circuit tester 13, two 8 terminal block and two RJ45 interface compositions, described circuit tester, the gear of 1 is allocated to diode measurement gear, two 8 terminal block are divided into the one 8 terminal block 11,2nd 8 terminal block 12, two RJ45 interfaces are divided into a RJ45 interface 14, the 2nd RJ45 interface 15;8 groups of corresponding terminals of the one 8 terminal block 11 are parallel to together by connecting line and are connected on a RJ45 interface 14,2nd 8 terminal block 12 is connected on the 2nd RJ45 interface 15, is inserted on a RJ45 interface 14 and the 2nd RJ45 interface 15 with the netting twine 100 of RJ45 connector at two ends.Circuit tester "+" and " " pole be respectively connected on any two port of the 2nd 8 terminal block 12.Utilize circuit tester can the characteristic of break-make of testing circuit, when circuit tester gear is allocated to diode measurement gear (buzzing gear) position, inside the loop of Guan Bi, circuit tester is sounded a buzzer sound, and inside the loop disconnected, circuit tester does not send sound.Eight independent cores inside netting twine are considered as eight road power circuits by us, it is divided into 4 groups, every both threads Lu Weiyi group, respectively to often organize circuit carry out circuit break-make measure, when circuit tester sends buzzer sound, represent this group circuit no problem, otherwise, these group circuit existing problems, check often organizing circuit successively, investigate netting twine Problems existing.Check whether netting twine head does qualified, whether there is netting twine head virtual pressure phenomenon, netting twine head compacting or cut is done again, carry out netting twine test process when using circuit tester, 4 groups of tests all do not send sound, and this is probably inspection netting twine and is not same netting twine or netting twine suffers extraneous physical damage.Eight independent cores inside described netting twine are divided into 4 groups, every both threads Lu Weiyi group, respectively to often organize circuit carry out circuit break-make measure, when circuit tester sends buzzer sound, represent this group circuit no problem, otherwise existing problems.
