The wear and tear of the connector pins is an unavoidable problem in use. Whenever a connector goes through the mating process, the resulting friction gradually removes the contact coating that provides corrosion protection to the pins, and with the loss of that coating, the connector's performance deteriorates.
There are two main reasons for the wear of the connector. The first is the wear that occurs each time the connector is plugged and unplugged. At this time, the contact surfaces of the plug and the socket slide against each other. The second is the wear that occurs due to fretting movements during the use of the connector. Fretting motions are small-scale motions caused by mechanical disturbances or thermal expansion mismatch forces, ranging from a few microns to tens of microns. It can be said that as long as the connector is used, pin wear will inevitably occur.
To minimize wear and tear, manufacturers take pin stiffness into consideration when designing and manufacturing connectors. The higher the hardness of the pin material and the electroplating material, the more wear-resistant it is, and its service life can be increased accordingly.
To reduce the impact of wear and tear on connector usage, you need to choose a good manufacturer. TXGA, a professional connector manufacturer, produces a variety of connector products, with sufficient inventory, fast delivery, support for customization, and one-stop purchase.
