Waterproof USB socket waterproof USB connector, as the name suggests, refers to a USB socket and connector with waterproof function. There are many types of USB sockets, and the USB socket I am talking about is not a finished plug-in socket, but a semi-finished product, a component. In fact, the waterproof USB socket I am referring to here is a waterproof USB connector, but some people call it different.
Our company specializes in providing waterproof USB sockets, in addition to waterproof touch switches. I have previously learned about the production process of 6 * 6 waterproof touch switches, how to detect waterproof touch switches, and the application and packaging specifications of waterproof touch switches. These are indirectly related to understanding waterproof USB sockets.
Waterproof USB socket basic performance of waterproof USB connector
1、 Electrical performance: The main electrical performance of USB sockets includes contact resistance, insulation resistance, and electrical strength.
2、 Environmental performance: The common environmental performance of USB sockets includes temperature resistance, humidity resistance, salt spray resistance, vibration and impact resistance.
3、 Mechanical performance: including the mechanical lifespan of USB sockets and USB connectors, which is determined by one insertion and one extraction cycle to determine whether the USB socket can complete its connection function normally after the specified insertion and extraction cycle. In terms of connection function, insertion and extraction force is an important mechanical performance. The insertion and extraction forces are divided into insertion force and extraction force (also known as separation force), and their requirements are different.
The function of waterproof USB socket and waterproof USB connector coating
1、 The surface of the ordinary metal coating is covered with an oxide film, which ensures that the oxide film will rupture when matched with the waterproof USB socket, ensuring that the contact interface is no longer oxidized.
2、 The precious metal coating has relatively simple metal contact with the interface and maintains the stability of the contact interface impedance.
3、 The coated USB socket is not easily oxidized and sulfurized.
4、 To optimize the electrical performance of USB sockets, establish and maintain stable USB socket impedance.
5、 It can improve the mechanical performance of USB sockets to a certain extent and enhance their wear resistance.
Development direction of waterproof USB socket and waterproof USB connector
The development direction of waterproof USB sockets and waterproof USB connectors should be high-speed transmission, miniaturization, high-density, and high-frequency.
1. High speed transmission refers to the requirement of modern computer, information technology, and networking technology for signal transmission with a time scale rate of megahertz frequency band and a pulse time of sub milliseconds. Therefore, it requires a waterproof USB socket and a waterproof USB connector for high-speed transmission.
2. Miniaturization refers to the smaller center to center spacing of waterproof USB sockets.
3. High density refers to the ability of waterproof USB sockets to achieve large core digitization. The total number of effective contacts for high-density PCB waterproof USB sockets is 600 cores, and specialized devices can reach up to 5000 cores.
4. High frequency is to adapt to the development of millimeter wave technology, and RF coaxial waterproof USB sockets have entered the millimeter wave operating frequency band.
