Connector with waved plate and sunken structure and terminal group thereof

The utility model discloses a connector with a waved plate and a sunken structure and a terminal group of the connector. Wherein the terminal group comprises a plurality of signal terminals, a grounding part and two wave plates, the signal terminals can be fixed with a core wire of a transmission line, one end of the grounding part can bear an insulating layer of the transmission line, the other end of the grounding part is provided with at least one grounding terminal, and at least one sinking bending section is arranged between the two ends of the grounding part. In addition, the two waved plates are assembled to the two side faces of the grounding part respectively, and the concave waved spaces of the waved plates can correspond to the core wire of the transmission line and the local part of the signal terminal, so that the two ends of the grounding part can be located in different horizontal planes through the sunken structure formed by the sunken bent section. Therefore, one end of the transmission line
