The invention relates to a high-frequency connector socket and a processing method thereof, comprising a socket seat with a socket, and the outer circumference of the socket seat is coaxial with the outer circumference of the pin seat of a pin inserted into the socket. The center is the same size, and a ring of inserting bosses are arranged on the inner side of the opening of the jack. Slots are set on the wall of the socket to meet the impedance matching requirements of high-frequency connectors and ensure the continuity of electrical transmission. The depth of the socket is less than 85% of the socket depth, which can effectively prevent stress from concentrating on the end of the socket and improve the service life. The length of the slot is inversely proportional to the contact pressure of the socket and the pin. The length of the slot meets the insertion force requirements of the socket and the pin, and at the same time reduces the contact resistance. The socket is fatigue-resistant and prolongs the service life.
