Two points of test method so through the invention:

Step 1: n bis- is divided: it is high-end that 1~n/2 connects test;N/2+1~n connects test low side;

Step 2: it is high-end that continuation two points: 1~n/4 connects test;N/4+1~n/2 connects test low side, and n/2+1~3n/4 connects survey It tries high-end;3n/4+1~n connects test low side;

Assign to cannot be two points until two, i.e. m step :+-+-+-+-.

The pin position setting list tested every time is listed according to the two points of above methods, as shown in Figure 1 ,+: it is high that expression connects test End ,-: expression connects test low side.

Then the foot position of wire rod can be carried out two points one by one according to the sequence enumerated in Fig. 1 by us, carry out high pressure survey Examination;

Meanwhile we can not also be out-of-order also possible according to the sequence in Fig. 1, as long as completing to be set out in Fig. 1 All tests.

In test process, as long as there is primary unqualified, termination test immediately, and the high voltage parameter of the wire rod is judged It is unqualified;Only when the test result of all steps be all it is qualified, could judge that the high voltage parameter of the wire rod is qualified.

But when test result is unqualified, it is unqualified which foot position two points of methods of testing can not find out.

Illustrated below using the wire rod of 8 foot positions as example:

Because in wire rod, the relationship between foot position has short circuit and open circuit, if then the butt-swelling position of short circuit should be regarded as 1 foot Position, that is, whole equipotential during the test, are handled as a foot position.

The wire rod of 8 foot positions in example, the relationship between foot position are entirely open circuit.

High voltage parameter: ac voltage withstanding, 3 kinds of test items of DC break down voltage and insulation resistance are contained.

Step 1: carrying out two points for 8 foot positions, and foot position 1,2,3,4 connects that test is high-end, and foot position 5,6,7,8 connects test low side,

Test passes indicate: in foot position 1,2,3,4 between any one foot position and any one foot position in foot position 5,6,7,8 High voltage parameter be all qualified.

It is namely tested by step 1, the wire rod of 18 foot position, has been divided into the line of 2 mutually independent 4 foot positions Material is respectively designated as wire rod 14 and wire rod 58, if this 2 wire insulations are qualified, the high voltage parameter of entire wire rod With regard to qualification.

Step 2: first test whether wire rod 14 is qualified, and wire rod 14 2 is divided into 2 parts and tested by same method, foot Position 1,2 connect test it is high-end, foot position 3,4 connects test low side;

Same wire rod 58, same method processing, and two are divided into foot position 5,6 connect high-end, the foot position 7 of test, and 8 connect test low side.

It is qualified to insulate if test passes, between foot position 1,2 and foot position 3,4, between foot position 5,6 and foot position 7,8 absolutely Edge is qualified.

In other words, it is tested by step 2, the wire rod of 24 foot positions is continued the line for being divided into 4 independent 2 foot positions Material.

Step 3: the wire rod of 2 foot positions carries out two points again, that be exactly one connect test it is high-end, another connect test it is low End.That is exactly that foot position 1 connects high-end, and foot position 2 connects low side;Foot position 3 connects high-end, and foot position 4 connects low side;Foot position 5 connects high-end, and foot position 6 connects Low side;Foot position 7 connects high-end, and foot position 8 connects low side.

Process described above is arranged for table, as shown in Fig. 2,+: expression connect test it is high-end-: expression connects test Low side.

Two points of processes above are depicted as shown in Figure 3 by we:

1, it is tested by step 1, is 2 independent parts by two points of complete 8pin wire rod (number 1):

2.1 (foot positions 1,2,3,4)

2.2 (foot positions 5,6,7,8).

We it can be concluded that, as long as 2.1 and 2.2 high voltage parameters are qualified, then entire wire rod 1 is qualified.

2, it is tested by step 2, continuing two points 2.1 and 2.2 is 4 independent parts:

3.1 (foot positions 1,2)

3.2 (foot positions 3,4)

3.3 (foot positions 5,6)

3.4 (foot positions 7,8).

We it can be concluded that, as long as 3.1 and 3.2 high voltage parameters are qualified, then 2.1 qualified;As long as 3.3 and 3.4 high pressures Parameter is qualified, then 2.2 is just qualified.

3, it is tested by step 3, it is 8 independent parts by 3.1,3.2,3.3,3.4 two points that we, which continue two points:

Namely single foot position 1,2,3,4,5,6,7,8.

We it follows that

High voltage parameter between foot position 1 and foot position 2 is qualified, then 3.1 is just qualified;

High voltage parameter between foot position 3 and foot position 4 is qualified, then 3.2 is just qualified;

High voltage parameter between foot position 5 and foot position 6 is qualified, then 3.3 is just qualified;

High voltage parameter between foot position 7 and foot position 8 is qualified, then 3.4 is just qualified;

So the wire rod high voltage parameter is qualified when the test result of each step is qualification, that is, meet: wire rod is appointed The high voltage parameter anticipated between two foot positions is qualified.

But simply by the presence of primary unqualified, which is just judged to unqualified.

It summarizes: needing to test by 28 times according to theory, after two points of test methods, it is only necessary to 3 times, greatly mention High testing efficiency.As pin number amount increases, the superiority of the algorithm is more prominent, as shown in figure 4, the present invention can will test Number reduce toIt is secondary, the test request of high voltage parameter can be met.

The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention Range.
