What is the meaning of the USB connector to be gold plated?

Recently, in the customer email of Konnra Electronics, many customers were found to consult “What is the role of the metal plating of the USB connector socket?” In order to facilitate the user's inspection, Konnra Electronics engineers specially compiled this document and summarized the USB. Connector socket metal plating function.
USB connectors
The role of the metal plating of the USB connector socket is mainly manifested in five aspects, as follows:
USB connector
1. The coated USB socket is not easily oxidized and vulcanized.
2. It can improve its mechanical properties and enhance wear resistance to a certain extent.
3. Optimize the electrical performance of the USB socket, establish and maintain the impedance of the USB socket.
4. The precious metal coating is relatively simple to contact the metal that produces the interface, maintaining the stability of the contact interface impedance.
5. The surface of the general metal plating layer is covered with an oxide film to prevent the oxide film from rupturing when the USB socket is mated, ensuring that the contact interface is not oxidized.
Konnra Electronics engineers pointed out that the USB socket terminal plating function is also beautiful, protective, extending the life of the product, coating the surface of the product with corrosion-resistant materials. Mechanical or engineering properties also improve the lubricity of the product and the strength of the product, including Improve the electrical conductivity of the product, improve the reflectivity of light, reduce the contact resistance, improve the weldability of the product, and the like.

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and

Talking about the function, classification and working principle of OTG data line

  What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny   USB   interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being. The role of OTG is to realize data transfer between mobile devices wi

The optical fiber connector

图片
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Basic introduction A connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss (<0.5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small. Introduction Optical fiber con
