[0046] Comparative example and test example
[0047] Change the needle diameter d to The stranded elastic pin and the traditional inner layer of 3 beryllium bronze wires and the outer layer of 7 beryllium bronze wires are applied to a 100-core connector, respectively. Test verification, under the same conditions as the test sleeve and other conditions, the test results of the connector engagement force, connector separation force, contact separation force (that is, the pin separation force), and the number of plug life cycles are shown in the table 1 shows:
[0048] Table 1 The connector using the pin of the present invention and the connector using the traditional pin
[0049] Test verification data comparison table
