HF Coaxial plug connector

A high frequency coaxial plug connector, comprising:

• a pin plug connector;
• a jack connector;
• one of said pin plug connector and said jack connector having an external thread and the other said connector having a cap nut adapted to be screwed onto said external thread;
• a cap ring rotatable relative to said other connector and axially fixed relative thereof;
• an anti-turning device for said cap nut, said anti-turning device comprising:
• an axially toothed sleeve having sawtooth toothing formed thereon and being received in said cap nut in an axially displaceable manner, and an axially toothed ring having sawtooth toothing formed thereon and being secured to said one connector;
• resilient means urging said toothed sleeve in an axial direction toward said one connector when said connectors are coupled together;
• said toothed ring and said toothed sleeve being adapted to engage each other in locking engagement to prevent rotation of said cap nut relative to said external thread when said connectors are coupled together;
• and
• slot guide means by means of which said sleeve and said cap ring engage each other, said slot guide means comprising a pin fixed to said sleeve, means defining an axially extending slot in said cap nut and means defining a recess in said cap ring, said pin passing through said axial slot and engaging said recess;
• and said recess having two walls coverging obliquely, one said wall being defined by an axially extending shoulder and the other said wall being defined by a second shoulder which forms an acute angle with said axially extending shoulder, said second shoulder being so oriented that rotation of said cap ring in the unlocking direction automatically effects axial retraction of said sleeve in a direction away from said other connector.
