Cable connector for connecting a cable having a central conductor

A cable connector for connecting a cable having a central conductor, comprising:

• an outer shell having a cylindrical shape;
• an external conductive body mounted at least partially within the outer shell and defining a first accommodating cavity, a first through hole is formed in a wall of the external conductive body;
• an insulating housing provided in the first accommodating cavity and defining a second accommodating cavity, a second through hole is formed in a wall of the insulating housing;
• an internal conductive body provided in the second accommodating cavity and defining an insertion cavity, the internal conductive body is electrically isolated from the external conductive body by the insulating housing, a connection hole is formed in a wall of the internal conductive body and communicates with the insertion cavity, the external conductive body, the insulating housing, and the internal conductive body are positioned so that the first through hole and the second through hole are aligned radially with the connection hole;
• a fastener mounted at least partially in the connection hole and fastening the central conductor of the cable in the insertion cavity;
• and
• an insulation ring fitted over an outer circumferential surface of the external conductive body and movable between a shielding position, in which the insulation ring covers the first through hole, and a non-shielding position, in which the first through hole is not covered by the insulation ring, in the non-shielding position, a portion of the fastener positioned in the connection hole is exposed from the first through hole and second through hole that are aligned with each other.
