Embodiment
Below in conjunction with accompanying drawing and instantiation the utility model is elaborated.The utility model plug is as shown in Figure 1, and heart yearn point 1 is connected with heart yearn point 2, is connected resistance R 41 between heart yearn point 3 and the heart yearn point 7; Heart yearn point 4 is connected with heart yearn point 8, is connected resistance R 42 between heart yearn point 5 and the heart yearn point 9, and heart yearn point 10 is connected with heart yearn point 16; Be connected resistance R 43 between heart yearn point 12 and the heart yearn point 18, heart yearn point 13 is connected with heart yearn point 19, is connected resistance R 44 between heart yearn point 14 and the heart yearn point 20; Heart yearn point 15 is connected with heart yearn point 21, is connected resistance R 45 between heart yearn point 22 and the heart yearn point 23, and heart yearn point 24 is connected with heart yearn point 25;, all the other heart yearn points break off.
The current-limiting resistance plug adopts the XK24J26P plug, is the plating type connector, requires to carry out warding off for twice tin and handles, and what the core root should stay 0.5mm～1mm when needing the lead core of welding to ward off tin does not ward off tin length, does not allow scolder or flux residue to attach on insulating barrier; Require the length of bundle conductor, the height of resistance can not exceed the plug hood simultaneously, be not less than 3mm with plug hood end distance, and resistance can not be collided definitely with plug body.To be enclosed within the teflon tube that resistance R 41, R42 pin are complementary on the resistance pin; Weld resistance again; Solder joint uses the heat-shrink tube that is complementary with it to carry out the pyrocondensation insulation protection; After passing in the middle of the resistance two pins, outside resistance, twine again earlier more than 2 layers with alkali-free glass fibre band ET60JC174-80 then, it is firm with the colligation of alkali-free glass fibre rope.At last, by Fig. 1 and electric assembling wire table the shorting stub point is carried out checking.With the 3rd of the avometer test plug and 7 points, 5 and 9 points, the 12nd and 18 points, 14 and 20 points, the resistance value of R41, R42, R43, R44 and R45 between 22 and 23 should be in 4.3 Ω ± 0.3 Ω scope.Carry out 2～6,11～26 these insulation resistance inspections between points by Fig. 1 in plug end, insulation resistance requires greater than 50M Ω.Carry out the insulation resistance inspection between each point and the housing in plug end, insulation resistance requires greater than 50M Ω.
Socket is as shown in Figure 2, and heart yearn is put the electric self-test signal of electrical system on 1 junctor, and heart yearn is put the electric self check inverse signal of electrical system on 2 junctors; Positive source on heart yearn point 3,5,12,14,22 junctors, power cathode on heart yearn point 4,10,13,15,24 junctors, heart yearn are put priming system I positive pole on 7 junctors; Heart yearn is put priming system I negative pole on 8 junctors, and heart yearn is put priming system II positive pole on 9 junctors, and heart yearn is put priming system II negative pole on 16 junctors; Heart yearn is put priming system III positive pole on 18 junctors, and heart yearn is put priming system III negative pole on 19 junctors, and heart yearn is put priming system IV positive pole on 20 junctors; Heart yearn is put priming system IV negative pole on 21 junctors, and heart yearn is put priming system V positive pole on 23 junctors, and heart yearn is put priming system V negative pole on 25 junctors;, all the other heart yearn points break off.Socket is selected the XKE24R26ZP-H model for use.
The docking scheme of plugs and sockets is as shown in Figure 3; When unmanned plane is formally launched, in the current-limiting resistance plug insertion socket, power supply "+" "-" on the machine is connected to the priming system I～V on the machine; Current-limiting resistance of priming system I～V "+" series connection on machine; If priming system point bridge silk short-circuit conditions occurs after quick-fried on certain machine, current-limiting resistance can fuse, and power supply on the machine is not impacted guaranteeing.
Forget that for preventing the situation of changing the current-limiting resistance plug occurs, on the machine design of electrical system electric self-test signal, if what when emission, use is not priming system current-limiting resistance plug, then electric self-test signal can report an error, and stops the emission flow process.
The unspecified part of the utility model is a technology as well known to those skilled in the art.
