摘要

The content disclosed in the present specification relates to the provision of a sewer branch pipe connector capable of connecting various types of branch pipes and improving watertightness between the connectors and the connected pipes. According to an embodiment of the present disclosure, the sewer branch pipe connector has one end inserted into the perforation of the main pipe and in close contact with the inner surface of the main pipe perforation, and the other end is a connector formed to surround a part of the branch pipe, one end and the other end. These are connected to each other and formed in a cylindrical shape, and the outer surface includes an expansion band that is in close contact with the inner surface of one end of the connector and a fastening band that surrounds and presses the outer surface of the other end of the connector, and one end and the other end of the expansion band It is coupled to enable a sliding movement in a direction intersecting or spaced apart from each other, and the expansion band contracts or expands through the movement of one end and the other end.
