Abstract
The utility model discloses a connection terminal, a sealing connection terminal and a connector. The connection terminal is characterized by including a terminal body. A first accommodating groove and a second accommodating groove are distributed in the terminal body in a length direction. The first accommodating groove and the second accommodating groove both surround the whole periphery of the terminal body and are used for accommodating a sealing ring. The sealing ring arranged in the first accommodating groove is capable of moving from the first accommodating groove to the second accommodating groove under an action of a force and being kept in the second accommodating groove. Structure arrangement of the connection terminal guides the sealing ring to move in a process that the connection terminal is inserted into an accommodating hole so that so that it is not only ensured that the connection terminal is inserted into the accommodating hole of a casing successfully but also moving of the O-shaped sealing ring out of the groove and thus sealing effect is reduced is prevented. The sealing ring is guided to move so that damages on the sealing ring in the process that the connection terminal is inserted into the accommodating hole are prevented and the sealing effect is ensured.
