Specific embodiment,
By taking cable interface as an example, illustrate the application method of the device.
Signal transmission cable generally uses two class standards, and abbreviation B mark, C mark in industry, the general B that defines are designated as straight-through net
The line sequence arrangement of line, both ends crystal head is identical, and C is designated as intermediate retiform cable, and the line sequence arrangement of both ends crystal head is different
It causes.
From without, it is difficult to judge B mark signal wire or C mark signal wire, when application, is often easy to take
Then mistake changes a cable again, to take repeatedly replacement could be correct sometimes, sometimes, operator do not notice take be
The signal wire of which kind of standard, in connection after, display screen can not normally be shown, then, operator will open from control system
Begin to debug, finally found that it is cable mistake, in this way, many times can be wasted, may influence whether that user makes in the case where urgent
With display screen, unnecessary loss is caused.
The place that school experiment room learns as one enters society later for student and lays a solid foundation, therefore,
The technology that laboratory contacts the fields such as some industry spots, production line is vital.
Currently, manufacturer can distinguish the signal wire of various criterion without a kind of good method, people can only be relied on
To make marks, warehouse is stored classifiedly, and still, manual operation is missed with regard to error-prone, can not fundamentally be solved once neglecting
This problem.
Currently, display screen producer cable multi-purpose greatly is as signal wire, by crystal head sheet metal, towards oneself, (small tail is being carried on the back
Face, downward), from left to right line sequence, it is direct-through line that B, which marks signal wire, and the line sequence at both ends is consistent, specific as follows: it is green it is white, green, orange is white,
Indigo plant, Lan Bai, orange, palm fibre are white, brown.
It is cross spider that C, which marks signal wire, and both ends line sequence is inconsistent, wherein one end line sequence are as follows: green white, green, orange white, blue, Lan Bai,
Orange, brown white, brown, the line sequence of the other end are as follows: white, orange, green white, the blue, Lan Bai of orange, green, palm fibre is white, brown.
The specific operation process of the present apparatus is as follows:
Two cable ports are inserted at the both ends of cable respectively, successively press corresponding control button, observation first row refers to
Show lamp and second row indicator light illuminating state, if first row and second row indicator light are to correspond successively point from first
Bright, then the signal wire tested is that B marks signal wire, if first row indicator light and second row indicator light are not one-to-one points
Bright, then the signal wire tested is that C marks signal wire, and the apparatus structure is simple, facilitates operation, and can quickly test out signal wire
Standard has saved the time, improves work efficiency.With good application value.
Above-described embodiment applies cable test only to illustrate the application method and process of device, the operation side of other ports
Formula is similar, it is only necessary to corresponding signal wire are inserted into corresponding port, operated by control button.
By the brightness of the adjustable signal lamp of adjusting knob, more intuitive test effect can be found out in this way.
