The course of work of the present utility model is as follows: the output terminal interface that the multichannel multi-core cable that detect is inserted successively each latch of main frame, the other end links to each other with described terminal, detection signal is sent on each road by each latch of Single-chip Controlling in the main frame successively, if cable is normal, the situation that does not have broken string, twisted wire, the light emitting diode of terminal will show successively according to the order that main frame sends detection signal.For example setting display mode is following two kinds:
1. forward display mode: terminal shows that diode lights successively one by one by 1～8, promptly lights as follows: No. 1 bright all the other go out, No. 2 bright all the other go out, No. 3 bright all the other go out ... No. 8 bright all the other go out.
2. reverse display mode: terminal shows that diode lights successively one by one by 8～1, promptly lights as follows: No. 8 bright all the other go out, No. 7 bright all the other go out, No. 6 bright all the other go out ... No. 1 bright all the other go out.
If but in the forward display mode, display terminal shows not according to aforesaid way, for example No. 1 bright back is suspended a little while, and No. 3 are bright, and this illustrates that No. 2 core is obstructed, if No. 2 bright back No. 1 bright, core formation twisted wire be described 1, No. 2.
When eight cores all show finish after, light on a certain road, then Dui Ying this road figure place is cable in this corresponding way, when having a plurality of main frame according to showing that this road figure place and host number that number of times that way is glittering and forward and reverse display mode decide its correspondence are cable in this corresponding host number and way.A glittering forward display mode is the number one main frame when for example showing way, glittering once reverse display mode is No. second main frame when showing way, glittering secondary forward display mode is No. three main frame when showing way, and the reverse display mode of glittering secondary is No. four main frame when showing way.
Because of main frame constantly sends detection signal to cable, main frame no longer needs the staff to carry out coordinated manipulation, also need not distinguish the particular location of the other end on certain road, the staff is as long as insert which road that a certain road port just can be discerned its respective hosts immediately to display terminal, if there have broken string just can identify which core to be disconnected, if twisted wire is arranged, just can identify which core and which core generation twisted wire, so not only save manpower, and reduced working strength, improved work efficiency and accuracy rate.
Adopt the utility model to be widely used in and detect the cable that netting twine, telephone wire, polycore cable etc. have many inner cores, can adopt a main frame in the utility model, if tested way is more, can carry out in batches or adopt a plurality of main frames to detect simultaneously, also can use a terminal that each cable end is detected respectively, or a plurality of terminal detect simultaneously to each cable.
As another kind of embodiment of the present utility model, only need a main frame in the use, then can detect 8 route cables at most, do not need to install commutation circuit this moment, and described double throw switch promptly is not set, and do not distinguish the working method of main frame in actual mechanical process yet.
More than multichannel multicore testing device provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
