Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a combined high-frequency connector. Background Art

[0002] High-frequency connectors are common electronic connection devices. The structure of high-frequency connectors usually includes an iron shell, a plastic unit, a terminal seat, an indicator light and a back cover. The terminal seat further includes a terminal block, a first conductive terminal group and a second conductive terminal group. However, the structure of the conventional first conductive terminal group and the second conductive terminal group is unreasonable and cannot form an electrical space. Capacitive coupling effect is easily generated between the conductive terminal groups, resulting in "crosstalk" phenomenon, which affects the transmission quality.

[0003] However, the plastic monomers in the high-frequency connectors of the prior art are generally of an integral structure, which is difficult to manufacture. Therefore, in order to facilitate manufacturing, a modular high-frequency connector has emerged. The front shell and the rear shell in the modular high-frequency connector are generally connected by a connecting shell, which is prone to loosening between the front shell, the rear shell and the connecting shell. In addition, the connecting shell generally does not take heat dissipation into consideration. During the operation of the connector, the heat generated cannot be dissipated, which can easily affect the service life of the connector. Therefore, improvement is needed. Utility Model Content
