Problems solved by technology

[0004] (1) The test speed is slow: During the test process, the continuity and line sequence of the network cable need to be displayed in sequence. It takes about 5 to 10 seconds to test the continuity of a network cable, which takes a long time;
[0005] (2) The professional requirements for judging the accuracy of the line sequence are relatively high. For non-professionals, it is difficult to make an accurate judgment, especially for the judgment of whether the line sequence of the precursor line and the cross line is correct.

Abstract

The invention provides a network cable tester, and relates to the technical field of network maintenance equipment. The network cable tester comprises first and second network cable sockets, the firstnetwork cable socket is internally provided with four impedance circuits, and the second netting twine socket is internally provided with three impedance circuits; the output ends of the seven impedance circuits are connected with a comparison circuit, and the comparison circuit shapes and converts voltage signals output by the seven impedance circuits into digital signals; the output end of thecomparison circuit is connected with a logical judgment circuit, and the logical judgment circuit carries out logical judgment on the digital signals generated by shaping and conversion, and thus, obtains the type and conduction condition of a network cable to be tested; a network cable type and conduction condition display circuit is connected with a display screen, and the display screen displays the type and conduction condition, obtained by the logical judgment circuit, of the network cable to be tested. Thus, the network cable is detected, the conduction condition of the network cable tobe tested, a core connection manner in the network cable and the signal transmission quality of the network cable can be determined conveniently, and convenience is provided for users.

Description

technical field [0001] The invention relates to the technical field of network maintenance equipment, in particular to a network cable tester. Background technique [0002] The network cable is a common material for network connection. The common network cables in the local area network mainly include twisted pair, coaxial cable and optical cable. During the use of the network cable, due to factors such as the location or avoidance of the cable, operations such as pulling or bending the network cable may be performed, resulting in network cable failures, such as interruption of the connection between the network cable and the crystal head, internal disconnection of the core wire of the network cable, etc. [0003] At present, the detection of network cable faults is generally realized by a network cable tester. The specific implementation of the tester is: input high levels to one end of the eight core wires of the network cable crystal head in sequence, and then receive and...
