Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, this utility model mainly includes casing, DC source, self-inspection button AN, multiple instruction
Lamp and multiple diode, wherein, DC source include alternating-current switch K1, dc switch K2, voltmeter V,
AC fuse F1 and DC fuse F2.Fig. 1 gives this device and control stick wire harness 3 and driving
The connection diagram of lever switch 2, the control stick switch 2 in figure is two-position switch, and it has a power supply terminal
With two lead-out terminals, power supply terminal is connected with the positive pole of DC source by the power line in control stick wire harness,
Two lead-out terminals are referred to by two control lines in control stick wire harness and the first display lamp L1 and second respectively
Show that lamp L2 connects, therefore while operation control stick switch 2, by observing the first display lamp L1 and the
The light on and off of two display lamp L2 it may determine that two control lines of correspondence whether wiring is correct.Can also be by seeing
The light on and off examining other display lamp judge whether string phenomenon.
One control stick wire harness often connects multiple control stick switch, the power supply terminal of each control stick switch
Being connected with the positive pole of DC source by the power line in control stick wire harness, lead-out terminal passes through control stick respectively
Different control lines in wire harness connect from different display lamps.For the ease of observing, by display lamp according to being connected
Welcoming the emperor and sail the difference of lever switch and carry out packet and install, all display lamps being i.e. connected with same control stick switch divide
It is one group, in the border circular areas that often group display lamp is arranged on machine shell panel, constitutes a display unit；
Relative to the center of display unit border circular areas, the control stick that the direction at each display lamp place is corresponding is opened
The direction of operating closed is consistent.Such as two-position switch in Fig. 1, it is assumed that to the left during operating switch handle first
Display lamp L1 is bright, and during operating switch handle, the second display lamp L2 is bright to the right, then installed by the first display lamp L1
In the left side at border circular areas center, and the second display lamp L2 is arranged on the right side at border circular areas center, this finger
Show that lamp method for arranging can be prevented effectively from erroneous judgement.
Fig. 2 is the control panel of aircraft control stick wire harness combined test apparatus.This control panel is provided with four
Individual wire harness socket 9, two, top is used for connecting single-place plane control stick wire harness or two-seater aircraft front deck control stick wire harness,
Following two are used for connecting two-seater aircraft rear deck control stick wire harness.Control panel is provided with 9 display units, bag
Include eight bit switch display units 4,5, five two-position switch display units of two five bit switch display units
6 and a three-position switch display unit 8.First permutator K3, the second permutator K4 and the 3rd conversion
Switch K5 is three double redundant electrical pow er supply line conversion switch, for the conversion of double redundant electrical pow er supply circuit.
The operating process of aircraft control stick wire harness combined test apparatus is as follows: by control stick wire harness compbined test
Device keeps flat on the table, opens assay device upper cover and exposes the control panel of combined test apparatus, will examination
Alternating-current switch K1, dc switch K2 on experiment device are placed in bottom, by 220VAC power supply test cable one end
AC Power supply socket 7 top-right with assay device control panel is reliably connected, and the other end inserts on workbench
220V AC Power supply socket on.
The connection of validation test installation's power source cable correctly can power on to assay device rearward, connects alternating current 220V
Alternating-current switch K1, connects dc switch K2, voltmeter V and should show 5V voltage, otherwise, disconnect exchange and open
Close K1 and dc switch K2, deenergization cable, check 3A AC fuse F1 and 2A DC fuse
Whether F2 damages, and changes new product if damaged.
After voltmeter V display 5V voltage, press self-inspection button AN, 31 fingers of 9 display units in left side
Show that lamp all should be lighted.If indivedual display lamps do not work, should first fix a breakdown, then check.By above-mentioned
Operation finds, when the instruction of 5V voltage is abnormal, should disconnect rapidly 220V alternating-current switch K1, investigate thoroughly 5V rectified current
Source failure condition, does not fixes a breakdown, and does not allow to be again switched on power supply.
Review and validate control stick wire harness insulating properties to be measured good after；Disconnect alternating-current switch K1, drive to be measured
The plug sailing bar wire harness 3 is reliably connected with the wire harness socket 9 on control panel respectively.Connect alternating-current switch K1,
Connecting dc switch K2, D.C. voltmeter should indicate 5V voltage, afterwards nine driving on operation control stick
Lever switch, on corresponding panel, corresponding display lamp should be lighted, and drives the control stick being provided with double redundant electrical pow er supply circuit
Close, after first pass detection is correct, the corresponding double remaining permutatoies of conversion (the first permutator K3, second
Permutator K4 and the 3rd permutator K5 one of them), repeat detection one time, should be correct.As
The corresponding display lamp of fruit does not works, and illustrates to there is line fault, it is assumed that there are misses, break, string or latch
Connection error, display lamp all there will be abnormal phenomena.
Note: during detection, single seat, two-seater front deck cable do not allow to be simultaneously connected with test with two-seater rear deck cable.
This assay device is applicable not only to the comprehensive detection of single seat type aircraft control stick wire harness, is also applied for same type machine
The comprehensive detection of two-seat version control stick wire harness, improves the utilization ratio of equipment, reduces human error and work
Make intensity.
