The invention discloses a connector, a connector, a matched connector, a matched connector and a connecting assembly. The connecting assembly includes the connector and the matched connector. A terminal fixing portion of the connector is provided with terminal accommodating cavities for accommodating connecting terminals. Separators for separating adjacent connecting terminals are disposed as protruding between the terminal accommodating cavities. The matched connector comprises insertion holes and isolating slots provided on a female end seat. The separators are inserted into the isolating slots. One end of the connecting terminal is disposed on the body of the connector, and the other end is held within the insertion hole and is connectable with a terminal connecting piece of the matched connector. The invention prevents connecting terminals from interfering with each other to provide a higher secure connection performance, while maintaining smaller spacing therebetween.
