Patent attributes
An earphone adapter for being fastened to a cable includes a plug part, a socket part connecting with the plug part and a shell enclosing inner ends of the plug part and the socket part. Several portions of an outer surface of the shell protrude outward to form two first fastening blocks spaced from each other, and a second fastening block located between the two first fastening blocks. A bottom of each first fastening block is concaved inward to form a first fastening groove passing through a side thereof adjacent to the second fastening block. A top of the second fastening block is concaved inward to form a second fastening groove. A substantial middle portion of the cable is placed in the second fastening groove with two ends thereof being clipped in the first fastening grooves along two ends of the second fastening groove, respectively.
