Abstract

The invention proposes a connector (400) for surface mounting to a circuit substrate, the connector comprises an insulator (420), a center conductor (410) centrically mounted to the insulator and a shielding shell (430) externally mounted on the insulator, the shielding shell comprises a first portion for connecting the shielding shell with a connector and a second portion for surface mounting the connector to the circuit substrate, the second portion includes a body (432) and a plurality of solder legs (431) formed on the body, wherein the body comprises a shielding portion (434) surrounding an extending portion of the center conductor and at least one opening (433) configured to communicate inner space between the center conductor and the shielding portion with outside space of the connector when the RF connector is soldered to the circuit substrate.

Description

technical field [0001] The present invention relates to electrical connectors, in particular to a radio frequency connector having improved high frequency characteristics compared with conventional radio frequency connectors. Background technique [0002] RF connectors are electrical connectors designed to work in the radio frequency band. RF connectors are often used with coaxial cables to maintain the shielding provided by the coaxial cables. [0003] Figure 1a , 1b and 1c show a conventional surface mount type radio frequency connector 100 . The connector is composed of a central terminal 110, an insulator 120 and a shielding shell 130, wherein the shielding shell 130 is wrapped on the insulator 120, and the central terminal 110 is inserted into the center hole of the insulator 120 from the bottom of the insulator 120 (not shown in the figure). show). [0004] In general, this traditional radio frequency socket connector 100 is surface mounted to the figure 2 A sub...
