Detailed description of the invention
The utility model is described in more detail below in conjunction with the accompanying drawings.
A kind of aviation that this utility model provides conducting insulating test set of transit cable one to one the most only needs to be connected to by Aviation cable in test equipment, stir corresponding band switch, the corresponding display lamp of observation is bright or extinguishes, so that it may judge it is conducting or insulation between this Aviation cable adapter correspondence pin.Concrete integrated circuit figure is as shown in Figure 1.
From figure 1 it appears that the aviation tested in the present embodiment transit cable one to one has 30 heart yearns, it is respectively arranged with aviation electric connector XS1 and XS2 with 30 pins with XP1 and the XP2 end of transit cable one to one corresponding to aviation.Each pin of aviation electric connector XP2 correspondence one respectively is for indicating pin the connected aviation break-make display lamp of transit cable heart yearn break-make one to one, it is L1 that name here connects the break-make display lamp of pin 1, break-make display lamp L30 is arrived in name successively, described display lamp is the light emitting diode that can send green light, certainly, the display lamp of other types or other colors can also be arranged as required to into, the anode correspondence of 30 light emitting diodes connects each pin of XS2, by series operation display lamp L0 after the negative electrode parallel connection short circuit of 30 light emitting diodes, current-limiting resistance R1, the negative pole of power supply P1 it is connected to after activate switch K1, power supply P1 is a 6V direct voltage source.The negative pole of power supply P1 connects the moved end SA0-0 of three band switch SA0 of an one pole, each pole of three band switches of one pole connects the not moved end of ten band switches of an one pole, the SA0-1 pole, not moved end of corresponding band switch SA0 connects the moved end SA1-0 of band switch SA1, the SA0-2 pole, not moved end of band switch SA0 connects the moved end SA3-0 of SA0-3 pole, the not moved end connection band switch SA3 of the moved end SA2-0, band switch SA0 of band switch SA2；In band switch SA1, these ten poles of SA1-1 to SA1-10 are connected respectively 1 to 10 pins of aviation electric connector XP1, in band switch SA2, these ten poles of SA2-1 to SA2-10 are connected respectively 11 to 20 pins of aviation electric connector XP1, and in band switch SA3, these ten poles of SA3-1 to SA3-10 are connected respectively 21 to 30 pins of aviation electric connector XP1.Certainly, above-mentioned name and each pin simply check each position to each band switch, each pole for convenience with the corresponding annexation of band switch, later test is facilitated to carry out, other annexation or naming method can also be used, as long as meeting each extremely corresponding pin connecting aviation electric connector XP1 of band switch.
Above-mentioned give physical circuit framework of the present utility model, below the method for testing of cable conducting insulated test device is explained.
First, the tested aviation two ends of transit cable one to one are connected respectively on aviation electric connector XP1 and XP2, then start test.Activate switch K1 is closed, after run indicator L0 sends red light, starts to stir each band switch test；First 1 pin is tested, the movable contact SA0-0 of band switch SA0 is toggled it on stationary contact SA0-1, the movable contact SA1-0 of band switch SA1 is toggled it on stationary contact SA1-1, now 1 pin of the XS1 of aviation electric connector is linked in series loop, observe the display result of each break-make display lamp, and the aviation conducting insulation characterisitic of transit cable one to one is judged, concrete estimate of situation is as follows:
1) if it is indicated that lamp L01 is bright and remaining display lamp L02～L30 does not works, then show that 1 pin of the XP1 of tested cable insulate with remaining pin beyond 1 pin of XP2 with the 1 pin conducting of XP2 and 1 pin of XP1；It is to say, 1 pin of tested cable XP1 with between 1 pin of XP2 without open circuit, and, 1 pin of XP1 with between remaining pin beyond 1 pin of XP2 without short circuit；
2) if it is indicated that lamp L01 is bright and has one or more (such as L03 and L04) bright among display lamp L02～L30, then show that 1 pin of the XP1 of tested cable also turns on remaining corresponding pin of bright display lamp (such as 3 pins and 4 pins) in addition to the 1 pin conducting of same XP2；It is to say, 1 pin of tested cable XP1 with between 1 pin of XP2 without open circuit, but, 1 pin of XP1 with between remaining pin (such as 3 pins and 4 pins) beyond 1 pin of XP2 exist short circuit；
3) if it is indicated that lamp L01 does not works and remaining display lamp L02～L30 does not works, then show that 1 pin of the XP1 of tested cable insulate with remaining pin beyond 1 pin of XP2 with the 1 pin insulation of XP2 and 1 pin of XP1；It is to say, there is open circuit with between 1 pin of XP2 in 1 pin of tested cable XP1, and, 1 pin of XP1 is with nothing short circuit between remaining pin beyond 1 pin of XP2；
4) if it is indicated that lamp L01 does not works and has one or more (such as L03 and L04) bright among display lamp L02～L30, then show that 1 pin of the XP1 of tested cable insulate with 1 pin of XP2, but turn on remaining corresponding pin of bright display lamp (such as 3 pins and 4 pins)；It is to say, there is open circuit with between 1 pin of XP2 in 1 pin of tested cable XP1, and, 1 pin of XP1 is with there is short circuit between remaining pin (such as 3 pins and 4 pins) beyond 1 pin of XP2.
By that analogy, stir band switch SA0, SA1, SA2 and SA3, one by one remaining 2～30 pin of the XS1 of aviation electric connector are accessed circuit.The state of viewing lamp L01～L30 according to the method described above, it is judged that the pin of the XP1 of tested cable is with whether there is short circuit and open circuit between the pin of XP2.
After being completed, switch K1 is pushed on movable contact A1, tested aviation transit cable one to one is removed from test equipment.
Above-described embodiment gives the conducting insulated test device being applicable to aviation with transit cable one to one, as other embodiments, the device of other cables conducting insulation can also be designed to test for according to thought of the present utility model, and the number of cable core is also not limited to 30.
It is presented above this utility model specific embodiment, but this utility model is not limited to described embodiment.Under the thinking that this utility model is given; use the mode being readily apparent that to those skilled in the art that the technological means in above-described embodiment is converted, replaces, revised; and the utility model purpose that the effect played is essentially identical with the relevant art means in this utility model, realize is the most essentially identical; the technical scheme so formed is finely adjusted formation to above-described embodiment, and this technical scheme still falls within protection domain of the present utility model.
