Description

Technical Field

[0001] The utility model relates to the technical field of electronic component connectors, in particular to a novel spring pin connector. Background Art

[0002] Spring pins are a kind of precision connectors used in mobile phones and other electronic products. They are widely used in electronic devices for connection. With the rapid development of smart products, the demand for product functions is increasing, and the application of spring pins is becoming more and more extensive.

[0003] In the prior art, when the spring pin and the probe are mating with each other, they mostly rely on the elastic force provided by the spring inside the spring pin to achieve axial contact. If the mating end of the probe is in a needle-shaped structure, the spring pin and the probe can only achieve static contact; if the mating end of the probe is in an annular structure, the spring pin and the probe cannot meet the dynamic contact of rolling; if the mating end of the probe is in a planar structure, the spring pin and the probe cannot meet the dynamic contact of sliding, and the spring inside the spring pin and the needle head only abut against each other through the end. Since there are fewer contact points between the spring and the needle head, the spring pin cannot withstand the radial force under high vibration conditions, and the connection between the spring and the needle head is easily disconnected.
