Understand the basic structure of the coaxial connector, we will not be in a hurry to bridge the coaxial connector in their respective companies or homes. Let's take a look at the basic structural components of the rf coaxial connector. The basic structural components are divided into the following four categories.

    1. contacts (contacts)

    It is the core part of the rf connector to complete the electrical connection function. The contact pair is usually composed of a male contact and a female contact, and the electrical connection is completed according to the insertion of the female and male contacts.

    The male contact is a rigid part that is cylindrical (round pin), square (square pin) or flat (tab). Positive contacts are typically made of brass or phosphor bronze.

    The female contact, that is, the jack, is a key component of the contact pair. It relies on the elastic structure to elastically deform when it is inserted into the pin, and generates elastic force to form close contact with the male contact member to complete the connection. There are many types of jacks, such as cylindrical (groove, neck), tuning fork type, cantilever beam type (longitudinal slotted), folded type (longitudinally slotted, 9-shaped), box-shaped (square jack) And its hyperboloid wire spring jacks.

    2. insulator

    Insulators, also commonly referred to as bases or inserts, function to position the contacts at the desired position and spacing and to ensure that the contacts are between each other and between the contacts and the outer casing. Insulation properties. Excellent insulation resistance, withstand voltage performance and ease of processing are the basic rules for selecting insulating materials to be processed into insulators.

    3. the shell

    Also known as the shell, it is the connector's outer cover that provides mechanical protection for the built-in insulated mounting plate and pins, and provides alignment when the plug and socket are inserted to secure the connector to the device.

    4. accessories

    Accessories are divided into structural accessories and mounting accessories. Structural accessories such as collars, positioning keys, locating pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Install accessories such as screws, nuts, screws, coils, etc. The accessories are mostly standard and general.
