Coaxial connector

A coaxial connector for connecting a coaxial cable having a central conductor and an outer conductor to a receptacle having a central conductor and an outer conductor, the coaxial connector comprising:

• a housing connected to the outer conductor of the coaxial cable and having a tubular portion arranged to be press-fitted and locked into a groove provided in the outer conductor of the receptacle;
• a socket connected to the central conductor of the coaxial cable and arranged to be connected to the central conductor of the receptacle;
• and
• an insulating bushing mounted into the tubular portion of the housing and holding the socket;
• wherein
• the tubular portion has a substantially C-shape extending perpendicularly or substantially perpendicularly to a direction in which the tubular portion is press-fitted to the outer conductor of the receptacle, and has a gap extending parallel or substantially parallel to the press-fitting direction;
• and
• the tubular portion has three first, second and third locking projections to be press-fitted and locked into the groove provided in the outer conductor of the receptacle to extend perpendicularly or substantially perpendicularly to the press-fitting direction, the first locking projection being located at a position on a circumference of the tubular portion diametrically opposite to the gap, the second locking projection and the third locking projection being located at positions spaced away from the first locking projection by about 90° or more in a circumferential direction, and a circumferential length of each of the first, second and third locking projections is smaller than a circumferential interval between the first locking projection and the second or third locking projection.
