Rectangular connector twist pin High contact density precision twisted elastic pin (twist pin contact)

 Twist pin contact terminal:The production and manufacturing of Rectangular connector twist pin use gold-plated pin and thread to conduct position setting by automatic winding technology in the form of rotating concentric circles according to the standard angle, and use laser welding to weld the two ends of the twist needle. The fusion welding is smooth and firm, and the shape meets the angle design. Tolerance grade: it12, H12, H12. Heat treatment: hv340-360, the inner and outer circle wires are evenly divided, without loose wires and broken wires, Use the 0.58 + 0.01 Jack to check the separation force of the probe: between 0.25N and 0.8N. Beryllium copper C17200 is used for needle and thread, C2680 brass is used for needle body, electroplating requirements: 80u "for the whole bottom and 50U" for gold plating ". This kind of gold plating surface treatment can improve its plug-in resistance up to 50000-100000 times of high performance requirements. The resistance stability reaches the optimal state of all metal plug connection modes, with small volume, good contact and ultra-high times of plug performance.twist pin contact

May be shortened. For a given structure, all pin positions should be tested, and in any case

The number of pins should not be less than 10.

1. By "dry as moulded parts", the samples were wet at 95-98% relative humidity and 40 ℃

Then the pull-out test was completed immediately.

2. If possible, the measurement should be carried out in both directions, for example, push the pin longitudinally through the connector, and then pull it out

It's like pulling the socket out of the end plate. In order to get the correct reading, according to personal design, "push" and "pull" should be the same

On the contrary. In a particular design, the connector tail may be properly loaded. For accurate results, the pressure and tension
