Detailed description of the invention
Opening one's minds of interconnecting device is 2 features based on airborne equipment:
1) service condition of airborne equipment can be showed by the parameter of voltage and current, and when product et out of order, the magnitude of voltage of fault paths or current value are inherently overproof.
2) airborne equipment is cross-linked by electric coupler and aircraft, and airborne equipment is received by each connector on electric coupler and feeds back signal on machine, as long as therefore the electrical quantity measuring each connector just can grasp the mode of operation of product truly.
According to above-mentioned 2 features, the principle of interconnecting device is: interconnecting device one end is connected with aircraft by adaptor union, the other end is connected with airborne equipment by adaptor union, and the wire in two terminal adapters is corresponding one by one, each wire correspondence is connected by the switching latch on interconnecting device.
Interconnecting device is made up of aircraft end cable, equipment end cable, cross-over connection latch and interconnecting device, and cross-over connection latch inserts the measurement terminal on transfer box, to realize the connection of every root wire.The different label of measurement terminal marks.The adaptor union be cross-linked with interconnecting device is universal models, needs to manufacture 2 transit cables according to adaptor union models different on airborne equipment during use.One of 2 cables is the adaptor union of universal models, for connecting interconnecting device; Other end is airborne equipment adaptor union separately, for being connected respectively to airborne equipment and aircraft.
The application of interconnecting device:
1) cross-over connection latch can regard wire as, and when plugging, corresponding path conducting, measures this road magnitude of voltage by the measurement terminal on cross-over connection latch.
2), when taking out cross-over connection terminal, corresponding path open circuit, uses amperemeter/ammtr to connect into dead circuit, can measure this road current value.
3) during corresponding path open circuit, can to the measurement terminal incoming signal with aircraft coupling end, for carrying out in energising testing, to aircraft input test signal.
As shown in Figure 1, first arrange some to mounting hole in the base portion of interconnecting device, every a pair mounting hole installs a pair measurement terminal.The essence of each measurement terminal is the pass structure of a conduction, can be used for inserting the test pencil of the equipment such as volt meter, amperemeter/ammtr and signal source.
Corresponding a pair measurement terminal of each road signal that airborne equipment is crosslinked with aircraft.As shown in Figure 3, one in a pair measurement terminal is connected with aircraft terminal adapter, and another is connected with equipment connector.The essence of visible measurement terminal is cut off by each road signal path, then inserts a pair measurement terminal respectively at the cut-off part of each signal.
As shown in Figure 1, the wire be connected with aircraft end all imports the transit cable 1 be connected with aircraft; Accordingly, the transit cable 4 with equipment connection is all imported with the wire of equipment connection.As shown in Figure 3, one_to_one corresponding answered by the wire in two adaptor unions, and namely No. 1 wire of aircraft terminal adapter should use same group of measurement terminal with equipment end adaptor union No. 1 wire, by that analogy.
As shown in Figure 2, in order to make interconnecting device, there is commonality, the adaptor union be arranged on interconnecting device is universal models, and the adaptor union corresponding with it is also universal models, and the adaptor union being connected to aircraft is then different according to different products with the adaptor union being connected to equipment.By such design, when needing to measure different products, only need change different transit cables can meet the demands.Meanwhile, in order to make number of signals meet the demands, on interconnecting device, the logarithm of measurement terminal should be greater than the number of signals of the maximum product of number of signals.
Insert measurement terminal in signal path, make signal path present off state, measurement terminal is inserted cross-over connection latch and can make signal path conducting, profile as shown in Figure 4.
As shown in Figure 5, cross-over connection latch has the contact of 3 whole conductings, and 12, No. 13 contacts are acicular texture, for inserting measurement terminal, makes signal path conducting; No. 11 contacts are cavernous structure, the device measuring electrical quantitys such as volt meter easy to use, amperemeter/ammtr.
When outfield troubleshooting, can work as follows with interconnecting device, as Fig. 6:
1.: when plugging cross-over connection latch, signal path is connected, and No. 11 contacts of cross-over connection terminal can regard the measuring junction that each signal is drawn separately as, magnitude of voltage when can survey equipment work by this measuring junction.
2.: when taking out cross-over connection terminal, signal path open circuit, uses amperemeter/ammtr to connect into dead circuit, can measure this road current value.
3.: when taking out cross-over connection terminal, can to the measurement terminal incoming signal with aircraft coupling end, for carrying out in energising testing, to aircraft input test signal.
