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...

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...

The working principle of IDC termination method

图片
Introduction and background IDC termination method is often used in various applications. This termination technology has been successfully applied to a variety of industries where multi-contact mass termination and very economical. Multi-point cable termination can be achieved with insulation displacement  connectors (IDC)  because the termination force is relatively small (usually a few pounds, while crimping is hundreds of pounds). In addition, another advantage of this technology is that it eliminates the stripping operations required in crimping. Therefore, in many electronic applications, such large-scale terminations are often used when using multi-strand cables. In many cases, multiple flat cables are used for this very economical large-scale termination. However, discrete multi-strand cables can also be used to reduce costs because the steps of cable stripping preparation and terminal insertion are eliminated. This type of application provides rapid assembly of high-d...
