The model of the universal frequency connector is composed of two parts: the main name code and the structural form code, separated by a dash "-" in the middle. Other situations that need to be explained can be stipulated in the detailed regulations, and separated by dashes and structural form codes.

    The main designation code of the universal radio frequency connector adopts the main designation code commonly used at home and abroad. The main designation code of the special product shall be specified by the detailed specification.

    (2) The structure code of the universal radio frequency connector is composed of the parts shown in the following table:

    Standard order classification feature code mark content

    Plug socket

    Panel cable

    1. Plug or socket plug: T socket: Z(T)/(Z)

    2. The characteristic impedance is represented by the corresponding number /50 or 75/

    3. Contact form pin: J jack: KJ (K) K (J) K (J)

    4. Shell type: straight type: non-standard curved type: WW/W

    5. Installation form flange plate: F nut: Y welding: HF or Y or HF or Y or HF or Y or H

    6. Wiring type Cable: cable code Microstrip: D high frequency band: not standard cable code D cable code

    Note: For the series of plugs with pins and sockets with jacks, the codes of plugs and sockets (number 1 in the table) are not marked in the structure. For the series of plugs with jacks and sockets with pins, the codes in parentheses are used.
