The connection modes of the three leads L1, L2 and L3 and connection points A1, A2, A3, B1, B2 and B3 are six, and the connection modes are assumed as follows: one end of a lead L1 is connected with an A1 wiring point, and the other end is connected with a B1 wiring point; if one end of L2 is connected to a junction a2, the other end is connected to a junction B2, one end of L3 is connected to a junction A3, and the other end is connected to a junction B3, the results of the six tests should be: the first test is charged, the second test is uncharged, the third test is uncharged, the fourth test is uncharged, the fifth test is charged and the sixth test is uncharged. Therefore, the six lead connection modes correspond to six different measurement results through the six tests, and the corresponding lead connection modes can be obtained according to the different measurement results corresponding to each six tests.

In testing, to reduce the number of unnecessary tests, the execution logic of the six tests may be: first, a first detection result obtained by a first test is executed, if the first detection result is electrified, two connection modes of the three wires and the main machine and the auxiliary machine are shown, namely, the first connection mode is as follows: the two ends of L1 are respectively connected with A1 and B1, the two ends of L2 are respectively connected with A2 and B2, and the two ends of L3 are respectively connected with A3 and B3; the second connection mode is as follows: the two ends of L1 are respectively connected with A1 and B2, the two ends of L2 are respectively connected with A2 and B1, and the two ends of L3 are respectively connected with A3 and B3. In addition to these two connections, the remaining four connections should be uncharged when tested for the first time. According to the two wire connection modes corresponding to the electrification of the first test result, it can be concluded that the two wire connection modes are not electrified during the second test result, the third test result and the fourth test result, and it needs to be concluded which connection mode is the connection mode through the fifth test and the sixth test result, that is, if the fifth test result is electrified, the wire is the first connection mode, if the fifth test result is not electrified, the sixth test is carried out, and if the fifth test result is electrified, the wire is the second connection mode. Therefore, after the first test result is charged, the second test process, the third test process and the fourth test process are not required to be executed, the fifth test process and the sixth test process are directly executed, and therefore the test processes can be reduced.

Similarly, if the first measurement result is uncharged, the wire connection modes correspond to the other four types, and a second test process is required, and if the second test process is charged, the connection modes corresponding to the wire are still two types, which are respectively a third connection mode: the two ends of L1 are respectively connected with A1 and B1, the two ends of L2 are respectively connected with A2 and B3, and the two ends of L3 are respectively connected with A3 and B2; and a fourth connection mode: the two ends of L1 are respectively connected with A1 and B3, the two ends of L2 are respectively connected with A2 and B1, and the two ends of L3 are respectively connected with A3 and B2. According to the third and fourth wire connection modes corresponding to the second test result being charged, the results of the third and sixth test should be uncharged, and it needs to be inferred through the fourth and fifth test results which indicate that the wire is the fourth connection mode if the fourth test result is charged, the fifth test result is uncharged, and the third connection mode if the fourth test result is charged. Therefore, after the second test result is charged, the fourth test process and the fifth test process can be directly executed without executing the third test process and the sixth test process.

Similarly, if the first and second test results are both uncharged, the method corresponds to the last two wire connection methods, that is, the fifth connection method is: the two ends of L1 are respectively connected with A1 and B2, the two ends of L2 are respectively connected with A2 and B3, and the two ends of L3 are respectively connected with A3 and B1; and a sixth connection mode: the two ends of L1 are respectively connected with A1 and B3, the two ends of L2 are respectively connected with A2 and B2, and the two ends of L3 are respectively connected with A3 and B1. And deducing a fifth and a sixth wire connection modes corresponding to the charged third test result, wherein if the fourth test result shows that the wire is charged, the wire is the sixth connection mode, and if the wire is not charged, the wire is the fifth connection mode. If the first, second and third measurement results are not charged, the line is not connected, and other sockets need to be replaced for connection testing.

Each set of wires may also contain more than three wires, and when more wires are contained, it is necessary to increase the number of connection points in the terminal openings and to increase the number of tests according to the above-described test procedure principle, so as to be able to perform a multi-wire test.
