Description
Technical field
The invention belongs to non-source test field, and in particular to a kind of terminal module for cable conduction detection.
Background technology
Existing testing lines system is that tested cable is connected with test equipment after test cable switching, such as Fig. 1
Shown, tested cable two ends are required for being transferred with test cable；After cable installation is laid, transit cable uses very stupid
It is heavy, mixed and disorderly.By taking aircraft as an example, as shown in Fig. 2 wanting test drives cabin flight control computer to the cable between afterbody elevator
Component,, at a distance of more than 50m, using transit cable test, two ends total cable length have to be larger than 50m, now transit cable for both
Length, weight can have a strong impact on testing efficiency.
The content of the invention
The purpose of the present invention is：Traditional two ends test is converted into into single end testing, whole electric cable Aulomatizeted Detect is solved
Used in a large amount of technique transit cables problem, optimize cable detection mode.
The terminal module for cable conduction detection of the present invention, is provided with connector portion in the opening of shelter-clad
Part, includes electronic devices and components inside the shelter-clad, the electronic devices and components include multigroup by electronic diode and resistance
The one-way conduction circuit of composition, two end points pin connection corresponding with the connector component of every group of one-way conduction circuit；
When detecting to cable, by the terminal module and cable connection, by imposing test in the corresponding pin of the cable other end
Signal is judging the conduction property of cable.
Further, also include filling heat conduction glue-line and isolating shrinkable tube in shelter-clad.
Further, when the core number of tested cable is odd number, there are two groups of one-way conduction circuits that there is a common port.
Relief cable tester is capable of achieving the single end testing to cable, and during detection, positive power-up conducting is reversely obstructed, with
This is judging the conduction property of tested cable.
Beneficial effects of the present invention：By using terminal module in a test system, make whole test system more succinct,
Avoid in whole machine testing lines process in a jumble, significantly improving test environment, improve testing efficiency.It is embodied in following side
Face：
Independent loop is converted into series loop by components and parts in terminal module by 1, and two ends test is converted into single-ended survey
Examination, simplifies test system.
2 because being converted into single end testing, so test node number halves, testing efficiency improves 50%, while reducing to surveying
The performance requirement of test system main control unit.
3 can connect end according to actual environment on machine, the executor or sensor by wing, empennage, undercarriage etc. in distal end
End module, need not lay transit cable, reduce time；Selection operation space than larger termination as test lead, for example
Using the driving cabin of electronic equipment concentration, cargo hold as test lead, only just need to be capable of achieving using very short transit cable in test lead
Test, improves testing efficiency.

Specific embodiment
1 model of connector component of terminal module is determined according to the other end adapter model of tested cable, according to test
The conducting principle mandates of instrument, calculate 6 component parameter of diode 7 and resistance.
According to the core number of tested cable, the quantity of diode and resistance element is determined, when core number is odd number, connection is shown
It is intended to as shown in figure 3, when core number is even number, connection diagram is as shown in Figure 4.
To ensure the connective stability of electronic devices and components and contact, heat conduction glue-line 2 is filled in weld, both ensure connection
Device, meets the cooling requirements of electronic devices and components again, increases isolating shrinkable tube 4 in the lead exposed section of electronic devices and components, to ensure
Insulating properties；Outside in termination module increases metal skirt 5, to protect internals.
Terminal module is passive electrical devices, and its operation principle during cable detection is as shown in figure 8, specifically such as
Under：
1 positive power-up：A1 ends are powered up, diode 7 turns on, theoretical current flow direction is A1-A2-R1-D-B2-B1, i.e. A1,
B1 is turned on.
2 reversely powering ups：B1 ends are powered up, theoretical case A1, B1 is obstructed because diode ends.
A1, B1 conducting is judged by positive power-up, short circuit between A, B path is excluded by reversely powering up, it is whole so as to judge
The correctness in loop, its critical table are as follows.
