Description

A connector socket with weldable wire radio frequency contacts

technical field

The utility model relates to the improvement of a connector socket with a weldable wire radio frequency contact piece.

Background technique

Refer to FIG. 2 for the radio frequency contacts installed on the existing connector sockets with radio frequency contacts. It consists of a square shielding shell 1 and a radio frequency connector 2 integrally connected with the front end of the square shielding shell 1 . The radio frequency connector 2 can be a jack structure or a pin structure. Inside the square shielding case 1 there is a cavity 9 coaxial with the radio frequency connector 2 , and the inner conductor 3 of the radio frequency connector 2 protrudes into the cavity 9 inside the case 1 . There is a hole on the rear end face or one side of the square shielding shell 1, and the inner conductor 3 of the radio frequency connector 2 protrudes directly from the hole on the rear end face of the square shielding shell 1, or from the side of the square shielding shell 1 after bending 90°. The hole sticks out. Its shortcoming is: the internal conductor 3 of this structure is only suitable for being connected with the printed board, is not suitable for being connected with the wire. Therefore, the connector socket with this radio frequency contact can only be welded with the printed board, but cannot be directly welded with the wire. However, in electronic equipment, due to structural requirements, wires are often used for signal connection between two circuit boards, and sockets with existing structures cannot meet the above requirements.

Detailed ways

Below the utility model is described in further detail. Referring to Fig. 2, the connector socket of the present utility model is composed of a socket shell formed by fastening a socket insulating pressure plate 11 and a socket insulator 12, and a contact piece installed in the shell. The above-mentioned contact piece is one of the following four situations: a. The contact piece is a radio frequency contact piece 13; b. The contact piece is a mixed contact piece composed of a radio frequency contact piece 13 and a non-radio frequency contact piece 14; c. The contact piece is a radio frequency contact piece 13 and a non-radio frequency contact piece 14 and a high-power A mixed contact piece composed of contact piece 15; d, the contact piece is a mixed piece contact piece composed of radio frequency contact piece 13 and high power contact piece 15; the above-mentioned radio frequency contact piece 13 includes a square shielding shell 1, a The front end of the radio frequency joint 2 is connected as a whole. There is a cavity 9 coaxial with the radio frequency joint 2 inside the square shielding shell 1. The inner conductor 3 of the radio frequency joint 2 extends into the cavity 9 inside the shell 1.
