About connector friction corrosion and plating problems

图片
It is well known that corrosive gases, high humidity and strong oscillations are three important conditions that cause oxidation and frictional corrosion and lead to connector failure. These environmental factors can have a significant impact on tin and lead-tin contact surfaces, as is the case with 90% of connector surfaces. Usually, people use electroplated precious metals, such as gold plating or silver plating, because these metals do not oxidize. The thickness of these coatings varies from 0.5 μm to 1.27 μm. However, unfortunately, because of the high price of these precious metals and their processing, such electroplating processes are expensive, so people use such electroplating materials as little as possible. In automotive electrical harness applications, only about 10% of the connection points use this type of metal. As a result, some major connector suppliers, such as FCI, have other alternative plating solutions (such as pure tin plating, Tin-Teflon, NXT, and press-fit t

What is a wire to wire/wire to board/board to board connector?

In the connector industry, connectors are divided into three categories: wire to wire connectors, wire to board connectors, and board to board connectors depending on the properties of the connectors connected to the connectors. However in the day Often used, there is no absolute distinction. Many connectors can be used in two or even three cases. How do we distinguish between these connectors? Konnra Electronics specializes in the production of connector products. According to incomplete statistics in the industry, we can roughly distinguish as follows: What is a  wire to wire connector ? Wire to wire connectors are typically connectors that work between wires and cables or between cables and cables. What are the main  wire to  wire connectors? In the connector industry, there is also a product called a connecting wire, which is also known as a terminal wire, and one end has a terminal and the other end is soldered.

To understand the usb interface, you must first understand its concept. In English, usb is the abbreviation of Universal Serial Bus, translated into Chinese is the meaning of "universal serial bus". It is not a new bus standard, but a new interface technology for PC applications. In 1995, the usb interface was already used on the PC, but due to the lack of software and hardware support, the USB ports of these PCs were idle. Until 1998, with Microsoft's built-in support module for USB interface in Windows 98, and the increasing number of USB devices, the USB interface gradually entered the practical stage. USB uses a 4-pin plug as a standard plug. With this standard plug, all peripherals can be connected in a daisy chain without losing bandwidth. The USB standard divides USB into five parts: controllers, controller drivers, USB chip drivers, USB devices, and client drivers for different USB devices. USB requires support from the host hardware, operating system, and p
