RF connector fundamentals- RCA connector
RCA Plug and Jack is a press-fit plug and jack connector with one conductor plus ground introduced (in the 1930’s?) by Radio Corporation of America, now part of Thomson Electronics.
The jack is a metal stud a little larger around than a pencil (about 3/8 inch) with a center hole that a small lollipop stick would fit (about 1/8 inch). The matching plug has one fat (1/8 inch) center pin that represents the live conductor, and a shell that presses onto the jack stud and that is almost always grounded.
Normally the center pin is connected to the center conductor of a coaxial cable and the shell is connected to the shell or shield of the cable.
An RCA connector is a plug and a jack designed for use with coaxial cable for frequencies ranging from the very lowest up to several megahertz.

The male RCA plug consists of a central pin measuring approximately two millimeters (mm) in diameter, and an outer shell whose inside diameter is approximately six mm. The plug shell is slotted rather than threaded, to facilitate quick insertion to, and removal from, the female jack or receptacle.
