Several ways of configuring coaxial cable and coaxial connector

Before testing and measuring, installing cables and Coaxial connector And coaxial components require a lot of design work, committed to selecting the best coaxial cable and connector for the project. These factors include electrical characteristics, mechanical characteristics, infrastructure logistics, price, environmental assessment, standards and qualifications.

Coaxial connector

In addition to cables and connectors, there are more coaxial assembly and installation. These portable RF tools must be equipped with hardware and components to ensure good RF operation and electrical isolation. In addition, maintenance is also common and requires tools to maintain these systems on site and in the factory.

1. EMI / RFI attachments.

The shield of the coaxial cable assembly provides high isolation of intrusion signals from the surrounding environment, but the connection between the shield connector and the housing is not always shielded. Therefore, EMI / RFI gaskets can be used to ensure the complete sealing of the metal housing of the bulkhead connector and coaxial assembly, which can provide a higher level of isolation of the whole assembly.

Depending on the type of connector format, ring and flat washers are available. For example, SMA pads typically use flat 4-hole flange connector pads and ring pads.

2. Nuts and bolts.

Many diaphragms or flanges Coaxial connector Nuts and bolts are required to connect to the assembly. Generally, we all know the correct type, size and screw of the screw, and the flange needs to be correctly connected to the housing. The material composition of these screws is sometimes very important because some environmental factors will lead to galvanic corrosion or other deterioration effects, which will eventually reduce the performance or failure of the equipment / system. Fasteners are common failure modes of complex components and systems.

3. Brackets and other hardware.

Inline coaxial elements may be subjected to significant mechanical stresses. Typical coaxial cables and connectors are designed to accept a certain degree of stress, but in internal components, any fracture in the line can concentrate these stresses on discontinuities. Therefore, support structures such as supports and tie rods are usually worth ensuring consistent placement and reducing the stress of these important connections.

Dust and microsomal debris may be present in any coaxial system, whether indoors or outdoors.Coaxial connector And any particles in the line will reduce RF performance and even cause sparks and faults at high power levels. Due to the nature of RF energy, even the coaxial ports of unused components need to be properly connected to avoid interaction and interference with the external environment.

Compared with standard terminals, the dust cap of coaxial connector is specially designed to provide additional environmental protection. In addition, depending on the electrical requirements of a particular port, many of these dust caps can provide short-circuit or non short-circuit terminals. In addition, some dust caps can provide a safety chain to prevent the loss and damage of the cover when the port needs frequent access.
