Abstract
The utility model discloses a test bench for flat cables, which comprises a PCB (printed circuit board) base plate, a power supply seat, a current limiting resistor, a flat cable seat, a switch and a light emitting diode. The power supply seat, the current limiting resistor, the flat cable seat, the switch, and the light emitting diode are all welded on the PCB base plate; the light emitting diode is connected with the flat cable seat through printed wires; the current limiting resistor is connected with the flat cable seat through printed wires; and the power supply seat, the switch, the current limiting resistor, and the light emitting diode are electrically connected with each other. The test bench can greatly save the time for testing flat cables and has the advantages of zero missed detection rate, convenient operation, and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of test board, relates in particular to a kind of easily-testing platform of flat cable.
Background technology
In electronic equipment, use the interconnection that flat cable carries out device interior spare and equipment room in a large number, when equipment is produced in batches, the test of a large amount of flat cables be very time-consuming again the effort.At present, the test of known flat cable has two kinds: one is to use manually with the multimeter test, not only time-consuming, and false pass rate is also very high; Two are to use the instrumentation test, and cost is higher and also higher to operative employee's requirement.
The utility model content
The utility model provides a kind of test board of flat cable at the deficiency of the measuring technology of existing flat cable.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of test board of flat cable, and it mainly is made up of PCB substrate, power socket, current-limiting resistance, flat cable seat, switch and light emitting diode; Described power socket, current-limiting resistance, flat cable seat, switch and light emitting diode all are welded on the PCB substrate; Light emitting diode links to each other with track with the flat cable seat; Current-limiting resistance links to each other with track with the flat cable seat; Be electrically connected between power socket, switch, current-limiting resistance and the light emitting diode.
The beneficial effects of the utility model are, the utility model can greatly be saved the test duration of flat cable, and false pass rate is zero, and both handled easily was cheap again.
Description of drawings
Fig. 1 is the structural representation of the test board of the utility model flat cable.
Embodiment
Because the making of flat cable is adopted the crimping mode according to the design feature of its connector, during making flat wire is placed on the harpoon type metal needle of connector pedestal, the connector pressure head is enclosed compressed moulding then, plugs protecting cover again.In this production run, because crimping tool and artificial origin cause that the bad possibility of product exists all the time, mainly shows as: the one, pressure is not enough, causes open circuit; The 2nd, put partially the flat wire position, causes to compress back adjacent lines short circuit.The utility model can effectively detect this two kinds of defective productss.
The utility model is described in further detail below in conjunction with accompanying drawing, and the purpose of this utility model and effect will be more obvious.
As shown in Figure 1, the test board of the utility model flat cable mainly is made up of PCB substrate 1, power socket 2, current-limiting resistance 3, flat cable seat 4, switch 5 and light emitting diode 6; Power socket 2, current-limiting resistance 3, flat cable seat 4, switch 5 and light emitting diode 6 all are welded on PCB substrate 1, and light emitting diode 6 and flat cable seat 4 link to each other with track; Current-limiting resistance 3 and flat cable seat 4 link to each other with track.Be electrically connected between power socket 2, switch 5, current-limiting resistance 3 and the light emitting diode 6.
During test, cable to be tested is inserted on the flat cable seat of the correspondence on the test board, after the energized, respectively odd bit lines and even bitlines are switched on by the odd even selector switch, when the odd even selector switch was got to odd bits, for the non-defective unit cable, bright entirely, the even number of lamps of odd number lamp this moment went out entirely; Again the odd even selector switch is got to even bit, for the non-defective unit cable, bright entirely, the odd number lamp of even number of lamps this moment goes out entirely; If when the odd even selector switch is got to odd bits, a certain (or a few) position odd number lamp does not work, then expression has a certain (or a few) bit line broken string (for defective products), in like manner, if when the odd even selector switch is got to even bit, a certain (or a few) position even number of lamps does not work, and then expression has a certain (or a few) bit line broken string (for defective products); If when the odd even selector switch is got to odd bits, a certain when the odd number lamp is bright (or a few) position even number of lamps is also bright, then expression has a certain (or a few) bit line and ortho position short circuit mutually (for defective products), in like manner, if when the odd even selector switch is got to even bit, a certain when even number of lamps is bright (or a few) position odd number lamp is also bright, and then expression has a certain (or a few) bit line and ortho position short circuit mutually (for defective products).Use the result according to reality, use test board of the present utility model and detect flat cable, the recall rate of defective products is 100%.
