Connector manufacturer contact material types

The production of a connector is inseparable from the choice of raw materials. Different materials can bring different effects. Therefore, it is very necessary for the connector industry practitioners to understand the knowledge of the connector materials. So, do you know what the connector contacts are? In the following, Konnra Electronics engineers will focus on what the connector manufacturer's contact materials are. 

Konnra Electronics engineers pointed out that the connector contact materials are generally three kinds: brass, phosphor bronze and beryllium copper. As for how to choose these three materials, it depends on the type of contact, the frequency of plugging and the connector. Depending on the electrical and environmental conditions of the work, the materials and usage of the commonly used contacts are as follows;
     1. Brass: Copper-zinc alloy, high conductivity (26%), but the elasticity is poor, the appearance is yellow. According to the different copper content, it is divided into different grades, such as C2600, C2680 (JIS model). Each model is also divided into different hardness grades, such as 1/2H, H, EH, SH. Commonly used for PIN pins, grounding strips, etc.
     2. Phosphor bronze: copper-tin alloy, low conductivity (13%), but the elasticity is better, the appearance is red. According to the different copper content, it is divided into different grades, such as C5195, C5210 (JIS model). Each model is also divided into different hardness grades, such as 1/2H, H, EH, SH. Commonly used for terminals with shrapnel, such as various wire terminals.
     3. Beryllium copper: It has the advantages of the above two kinds of alloy copper, high conductivity (40%), good elasticity, but expensive, less used in the connector.

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
