Description

[Detailed description of the invention] [Required 1] Based on the given wiring data, the current test target and the 4-1 (IM's -)] Measuring the insulation between a test terminal and another test terminal:
,,1. : ζ-11, one of the test terminals that will be tested for the time being is installed with a wiring test device that detects poor insulation terminals.
The test terminal that was originally connected to the test terminal 41 is replaced with a terminal with poor insulation. Defense 11-Shimono.

[Industrial application field]

The present invention relates to a wiring testing device used for testing wiring networks, particularly for testing insulation.

The wiring test equipment is used to test whether the wiring network, such as a printed wiring board, is correctly wired according to the design. Select the test terminal based on the wiring data C2 obtained by setting d1 nostem (○ to 1[) etc., and connect the force test end -r and the other test terminal. Test whether the conductivity or insulation between the wire and the wire is in accordance with the wiring data.

In other words, the test conducted by wiring test equipment B is the 11m test or insulation test in terms of clay, and in the continuity test, it is one of the The test terminal (hereinafter referred to as 1ILI I'lli!) and the other test terminal (hereinafter referred to as the side terminal)
) will be held in the evening 1-.

In the Kononigen U7 insulation test, in order to shorten the test time, note [16g, j child and register number phase 2)', fill terminal group terminals are collectively fj').

The wiring network to be tested usually has a large number of test terminals (+: JT, terminals inside and +3+) arranged regularly.

The continuity test and insulation test are performed in this order.

In addition, for the wiring test, first connect the terminals that are connected by wiring.

Just like the master, conduct the continuity test using 1 and 7).

Continuity failure occurred in these conductor II+ tests (
In case, 1. At that time, the 4th edition (note the light terminal) - 1 and L 2 were used to conduct insulation tests, but the first insulation test was performed with Low Show 1 - Death 1 - in Uradome, and all subsequent insulation tests were carried out. Do a short test.

The results of the wiring test are printed as test result data, etc. It is used for finding and repairing defective parts, but in this case, it is desirable that the output test result data does not include redundant or invalid data.

[Conventional technology]

The third example is an explanatory diagram of a conventional example.

Reference numeral 1 denotes a control unit that controls each part based on wiring data created by the SlW machine-aided design system.

2 is a first selection circuit which selects the terminal of interest under the control of the control unit 1;

This is an insulation measuring instrument that measures the insulation between the flange plate 11 and the phase-f (!III end Y).

In addition, in 5, there is a wiring network e to be tested, and the part thereof is illustrated in FIG.

In Figure 4, ■～■? ;t: +'lυ1r, and between these ends r there are 6 and 2 wires C as shown by the solid line, but the cross mark indicates a disconnection and the dotted line indicates -4' insulation failure7. There is.

Here-Otsu I'Ig+-7, (Note: 31 Note [-If terminal ■ is detected as a defective terminal in °C during the continuity test with terminal A, then after this, terminal ■ is Note Ll +'T. If you conduct an insulation test using the All Show] Death 1.

In this case, the terminal ■ is connected to the insulation tester 4 as the terminal 1): [-11' 4 terminals (connected to the insulation tester 4 as the lu11 terminal, including the terminal 1).

For this reason, terminals ■ and ■ should be insulated (I) and the good end (R).

In addition to being detected as 1+, the insulation is also not 1'ij:
? $l r and μ are made together C,: detected 4I.

Since the explanation is about 8 years old in the oil field, -1- In the example, there is a terminal with poor insulation.5. The force being detected is the end Y-L; t I l is firm.

There are cases where a large number of edges are considered to be insulation defects and are detected.

In other words, if the test result data includes a large number of ends -r that are considered to be defective ends Y, it becomes J-, and if the defective part is found or t4 [in the repair work, one work tfC, two There is a problem with getting back to negative #11.

Therefore, the first object of the present invention is to prevent test results Y-Y in insulation tests from including any terminals considered to be defective terminals. ).

As a result, when conducting an insulation test using terminal ■ as a 2-port terminal,
Only 1.7 and ■ are detected as defective terminals.
