3, the fastening swivel nut material on the cable fixed cover is metal, and intensity strengthens, so that connect more firm.
4, set up rubber ring in the fastening swivel nut so that the cable fixed cover when tightening rubber ring be extruded, the inner chamber of turgor cable fixed cover on the one hand so that connector is more firm with being connected of cable, on the other hand so that sealing effectiveness is better, is convenient to open-air use.
5, solid swivel nut is tightened the width of rear described rubber ring more than or equal to a pitch of cable outer conductor, so that a periderm of cable outer conductor evenly pushes, is connected firmly, and signal transmission is uniform and stable, when tail cable shakes, can reduce vibrations, increases protection.
6, the structure of cable fixed cover is simplified, and has removed inner chamber and the internal thread of its rear end so that cable fixed cover size reduction, process convenient, cost.
7, the contact-making surface of connector outer conductor rear end and cable outer conductor is set to tapered electrolysis, and extruding force strengthens, and contacts closelyr, improves laser propagation effect.
8, the front end of cable fixed cover arranges internal screw thread, and internal screw thread compresses the helical form cable outer conductor.Extruding force strengthens and evenly, contacts closelyr, improves laser propagation effect.
