Stranded Pin connector elastic contact is a key part of its structural characteristics directly affect the contact performance of the connector. Traditional connector jack is elastic, flexible jack do very small, it is difficult to ensure good contact and resistance to vibration and shock, and other properties.

1, due to the flexibility jack is not further miniaturization, which hindered the development needs of multi-line the number of electrical connectors to small, high-density direction, with the advent of flexible stranded wire pins completely overcome the Achilles' heel. Pin is stranded by three copper lines for the inner ring, seven beryllium copper lines for the outer, inner and outer rings reverse stranded at both ends of welding, pins the central bulge, the convex part of the diameter of the cutting garden elongation deformation and axial rotation, the contact part of the jack inside diameter, working hours due to power and the formation of seven in close contact with the jack. Its unique structural features, it has good flexibility and exposure to performance and special vibration resistance, impact resistance test to prove its impact acceleration (three directions of a total of 3,000 times) up to 150g. Stranded pin has a good flexibility of the plug feel extremely soft, with the following two characteristics: 1. Elastic pins with rigid jack plug, and adaptable to the position of the jack.
