Description
Technical field
The utility model is applied in airborne testing retrofit process, tests a kind of adapter between cable.
Background technology
Test repacking installation work need to will be distributed over the sensor harness of each point of observation of aircraft on machine, pass through test adaptor
Airborne Testing System is accessed after part.Test adaptor part is the interface that sensor is connected with test equipment, passes through test adaptor part
It can check the operating mode of sensor, or airborne testing equipment provides the input interface of analog simulation signal.
At present, testing crew, need to be by each observation when cockpit carries out signal check and test equipment fault diagnosis works
The cable of point disconnects, carries out interpretation to output signal respectively, while needs again in the airborne testing equipment that will emulate signal access.
When need to supplement test parameter if any new test request, increase sensor, the adjustment of corresponding test cable is difficult.Existing test
Substitute mode is using quick-release plug or switching wiring pile.Wire stripper, crimping contact pilotage, crimping are needed using the repacking of quick-release plug
Pincers, locator send the/tools such as taker, box spanner；Switching wiring pile mode needs to use electric iron, wire connection terminal and weldering
Tin.Crimping mode maximum feature is of high cost, and recycling rate of waterused is low, and higher to worker's field conduct skill set requirements, uses
Fracture of wire, bad needle phenomenon are susceptible in journey；Welding manner need to use ground 220V power supplys, be susceptible to during use desoldering,
The problems such as rosin joint.Both modes all increase field retrofit workload and work complexity.
Invention content
Goal of the invention
Design a kind of airborne testing test cable adapter, the switching of signal wire in being reequiped applied to airborne testing.
Technical solution
The adapter outer layer is polytetrafluoroethylene (PTFE) high molecular material, is resistant to 250 DEG C of high temperature, has good mechanical performance；
Middle layer filled rubber is as insulating layer；It is metal copper core inside adapter, it is ensured that contact impedance meets test requirements document, copper
The through-hole of 5 Ф 2 of core frontal design passes through for testing cable, the corresponding Position Design spiral shell of 5 Ф 2.5 in its side
Pit tests cable for locking.Adapter the right and left devises installation mounting hole, can be not only used for single fixation, and can be more
It is a to stack installation fixation, it is easy to extend.Concrete scheme is as follows：
Airborne testing test cable adapter, including rectangular copper core conductor 1, insulating protective sleeve 2, cable mounting hole 3, tight
Fixing bolt 4 and integral installation mounting hole 5,2 one-time injection molding rear enclosure of insulating protective sleeve in 1 outside of rectangular copper core conductor,
The side of rectangular copper core conductor 1 is equipped with cable mounting hole 3, for connecting conducting wire, is set on rectangular 1 another side of copper core conductor
There is fastening bolt 4, be fixedly mounted and use for fastening bolt.
Preferably, integral installation mounting hole 5 is equipped on the outer rim side of insulating protective sleeve 2.
Preferably, the naked head of cable is directly probeed into cable mounting hole 3, is fixed by fastening bolt 4, realize 5 line conductors and
It connects.
Preferably, several airborne testings are fixed with test cable adapter using stacked on top mode, between levels
It is fixed using 2.5 bolts of side Ф across integral installation mounting hole 5.
Advantageous effect
The purpose of this utility model is that the work complexity at abbreviation scene, reduction system debug workload；Specific implementation
Tester only needs wire stripper and small screw driver that the wiring work of test cable can be completed in the process；Hot- line test process on machine
The interpretation of middle sensor signal, analog simulation signal access test system need not all change existing cable connection, improve test
Cable reequips working efficiency, reduces test repacking cost.

Specific embodiment
For the prior art, a kind of airborne testing test cable adapter is designed, is installed using stack manner bolt solid
It is fixed.Cable is tested for AWG18~24, is goed deep into the through-hole of Ф 2 using the naked mode that connects, by the snap bolt pressure of top Ф 2.5
Firmly, the tools such as wire stripper and small screw driver are only needed during work on the spot, not only can guarantee good contact, but also can abbreviation scene
Work complexity, improves working efficiency.The adapter maximum can accept the electric current of 5A.The adapter includes inner conductor and (contains 5
The through-hole of Ф 2), it is external for fixing insulating layer.Insulating layer both ends set respectively Ф 2.5 tapped through hole and Ф 3 without
The through-hole of screw thread, for adapter to be fixed.A 2.5 tapped hole of Ф is opened in the through-hole side of Ф 2 above inner conductor,
It is locked using the screw of a Ф 2.5 in side.It stacks and fixes when patent of the present invention uses, pass through 2.5 screw threads of both ends Ф
The through-hole of hole and Ф 3 are staggeredly engaged, and are fixed using 2.5 countersink head screws of Ф.
This patent is described in detail with reference to Fig. 1-Fig. 4：
