Abstract
Disclosed is a connecting line detector, which is mainly used for detecting the faults of short circuit, circuit break, or zig-zag welding of multi-core connecting lines. Each row of lamps is disposed between two DB9 nine-pin serial ports, and the lamps in each row are sequentially corresponding to pins labeled from one to nine. The upper row of green lamps and the lower row of red lamps are respectively used for indicating the faults of circuit break and short circuit of a connected core wire. While a detection line is connected, zig-zag welding of core lines happens if the green lamps do not light sequentially from the left to the right. When a plurality of red lamps lights at the same time, short circuit happens in the core lines corresponding to the plurality of red lamps. The green lamp and the red lamp in front of each of the binding posts are respectively used for indicating circuit beak and short-circuit of corresponding core lines. The binding posts are sequentially corresponding to label 4, 3, 2, 1 on a small aviation plug from the left to the right. When the detection line is connected, the welding of the detection line is correct if the four green lamps light sequentially. When a plurality of red lamps lights at the same time, short circuit happens between the core lines corresponding to the plurality of red lamps.
Description
Affiliated technical field
The utility model relates to a kind of equipment that detects multicore connecting line, and the company that is mainly used in is to the detection of the multicore connecting line produced.
Background technology
Because accidentalia, company produces in the process of multicore connecting line (Serial Port Line, air plug line etc.), error situations such as weldering, welding intersection or solder shorts can appear leaking inevitably, big and the not enough science of this method workload of manual detection multicore connecting line quality condition, however also do not find this type of to be specifically designed to detect multicore wiring short circuit, open circuit and weld whether intersect the equipment of mistake on the market.Can relievedly use high-quality all kinds of multicore connecting line in order to ensure the user, consider under the situation of each side reality, the instrument of all kinds of multicore connecting line quality conditions of special this special detection of research.
Summary of the invention
The utility model technical issues that need to address are, overcome disadvantages of background technology, and the aluminium matter wiring detector of a small and light is provided.The main wiring two ends of detecting are: " serial ports head VS serial ports head ", " the four-core terminal that big air plug VS can link to each other with binding post ", " the four-core terminal that little air plug VS can link to each other with binding post " these three kinds of main multicore wiring open circuit, weld mistake and the three kinds of situations of short circuit of intersecting.
The technical scheme that its technical matters that solves the utility model adopts is: in line with straightaway principle, this equipment is indicated the opening circuit of corresponding wiring heart yearn, short-circuit conditions with green light and red light respectively, represent " heart yearn is communicated with; represent that when green light is not lighted welding disconnects " with " the green light indication is current in the traffic lights ", " red light indication ' NO ' " represents " having been lighted between the heart yearn of several red light correspondences short circuit mutually simultaneously; this welding mistake is allowed to anything but ", it is clear understandable to express the meaning, and white clear lamp glows among the figure.
Circuit connecting relation of the present utility model is: on the circuit board of aluminium matter cabinet inside, the nine kinds of needles of one serial ports stand links to each other with the pin of single-chip microcomputer, the nine kinds of needles of another serial ports stand be connected on again on 5 volts of power supplys after green light links to each other, when on the DB9 serial port stand that two serial ports terminals is inserted on the wiring detection case, namely constituted a loop.If the green light in the middle of the two serial ports pins is not to light successively but intersect to light, the heart yearn welding of the green light correspondence that then explanation intersection is lighted has intersected; If a certain green light is not lighted, then its corresponding heart yearn does not weld.
Big air plug stand (wherein is numbered 2,3 stitch and is considered as same stitch, be numbered 4,5 stitch and be considered as another same stitch, so see from the outside and to be equivalent to have four stitch) and little air plug stand be connected on the pin of single-chip microcomputer, four binding posts respectively connect on the power supply that is connected on 5 volts behind the green light again, have constituted a loop when connecting detection line between big air plug stand and the binding post or between little air plug stand and the binding post.If an end of detected quad is that big air plug head is (wherein in six cores of big air plug head, be numbered 2,3 stitch and be considered as same stitch, be numbered 4,5 stitch and be considered as same stitch) then it is connected on the big air plug stand, if an end of detected quad is little air plug head, then it is connected on the little air plug stand, and the other end of line is connected on four binding posts in accordance with regulations, if four green lights are not to light successively but intersect to light, the welding of the heart yearn of the green light correspondence that then explanation intersection is lighted has intersected; If a certain green light is not lighted, then its corresponding heart yearn does not weld.
And 9 red lights of indication serial ports short-circuit state and indication quad short circuit whether 4 red lights all directly are connected between single-chip microcomputer pin and the 5 volts of voltage, connection situation by scanning green light branch road decides whether lighting of red light, thereby indicates the short-circuit state of tested survey line.If have two or several to be lighted simultaneously in the red light in the middle of the two serial ports pins, then judge between its corresponding heart yearn short circuit has taken place.If have two or several to be lighted simultaneously in four red lights before the binding post, then judge between its corresponding heart yearn short circuit has taken place.
The beneficial effects of the utility model are: can detect opening circuit, weld and intersecting mistake and short circuit etc. of the heart yearn that connects.
