An embodiment of the utility model discloses a sealing ring plug and a vehicular terminal using the same. The sealing ring plug comprises a head, a body, a tail and a threading hole, wherein the transverse central lines of the head, the body and the tail coincide, the head, the body and the tail integrally form a single part, and the threading hole sequentially penetrates the head, the body and the tail; the body is a cylinder, the area of the first end face, connected with the body, of the head and the area of the second end face, connected with the body, of the tail are larger than the area of the end face of the body, and the first end face, the second end face and the outer surface of the body form an annular clamp groove; a plugging piece is disposed in the threading hole at one end, away from the first end face, of the head, and the plugging piece is connected with the periphery of the threaded hole in a sealed manner through an easy-to-break part. The sealing ring plug has the advantages that the interior and the exterior of the shell are isolated before a harness penetrates, good sealing performance between the edge of the threading hole and the edge of the harness by the diameter relation between the threading hole and the harness after the harness penetrates, and the sealing performance of the interior of the shell can be increased greatly.
