Coaxial Cable Connectors Designed for Use and Operation

Coaxial components are mostly used in RF applications or microwave applications except for some RF signals that need waveguide and other conductive components or devices, so coaxial components are widely used in aerospace, machinery, aircraft, indoor and outdoor fields. RF applications or microwave applications are basically the choice of coaxial components, but some RF signals require waveguide or planar wire components and devices. Therefore, examples of use in different locations can be perceived, including: components, desktop equipment or machine equipment, indoor, outdoor, aircraft, land vehicles, machinery, intelligent robots, aerospace, satellites, etc. Because of the wide range of applications, there are also various technologies and characteristics of coaxial cables and connectors. This kind of coaxial process assembly is also complicated and requires professional tools.

Coaxial Connector Cable Composition Some common coaxial cables and connectors are assembled using tools and methods specific to the standard family of products. Standard coaxial was first used in the field of national defense. Radio Guide or Type RG Coaxial originated in World War II and was listed in MIL-HDBK-216 in 1962. Later, RG-type coaxial cables also became popular. Therefore, RG Coaxial Cable Assemblies are general purpose special tools and practices, including inside the machine equipment, as well as hand tools and operations required during installation or maintenance. A typical RG-type coaxial cable is compose of four layers, although there are extra layer in many coaxial cables. The four basic parts of a coaxial cable are the outer protective sheath (insulator), the metallic shield, the electrically polarized conductor and insulator, and the central conductor. The coaxial connector design is basically the same except for the surface protection layer. Essentially, the metal shield of the coaxial cable or the outer conductor of the coaxial cable needs to be connected to the surface shield delamination of the coaxial connector as uniformly as possible, the dielectric insulator needs to be connected to the coaxial connector in the same way, so that the impedance change can be greatly reduced, and at the same time, the center conductor needs to be connected to the coaxial connector plug as uniformly as possible. Connector operation steps: To connect this type of connector, first remove the protective shell on the surface of the coaxial cable. The total quantity is required to refer to the end quantity of the high-precision laser-cut coaxial cable. In particular, care should be taken not to reduce the coaxiality of the coaxial cable while laser cutting the end of the cable, and to ensure that there are no residual metal fragments in the insulator. Typically, the protective shell is first removed by a precisely designed proprietary tool without damaging the surface shield of the connector, and then the shield of the foil, corrugated, or stranded conductor is mechanically and automatically removed to conform to the outer electrical conductor retention clip of the coaxial connector. Aft all of that above processes are complete, the portion of the insulating medium on the center conductor of the coaxial connector can be separated, thereby facilitate the electrical welding, crimping, or press fitting of the center conductor to the center pin clamp of the coaxial cable connector. Coaxial cable connectors generally have a ferrule, which is used to lift the mechanical device connector of the outer conductor of the cable and to ensure good RF shielding. When the coaxial cable and the coaxial cable connector are assembled by crimping, electric welding or other methods, the heat-shrinkable sleeve or adhesive tape is generally added to ensure that the sheath connection between the surface protective layer of the coaxial cable and the coaxial connector is more firm. The addition of a heat shrinkable sleeve or tape at the connection between the cable and the connector can reduce the stress at the connection between the conductor and the dielectric and ensure that the coaxial cable assembly can still work normally under certain stress, load or bending conditions.
