High frequency coaxial connector

A high frequency coaxial cable connector of the bayonet type for use with a high frequency coaxial cable of the type having an internal lead wire, an insulation body, an external conductor, and an outer sheath comprising:

• an outer installation means and an inner installation means;
• said outer installation means comprising an external locking sleeve having a bayonet connection groove and an outwardly extending claw, an internal contact sleeve having a longitudinal end portion coaxially disposed within said external locking sleeve, said longitudinal end portion of said internal contact sleeve having a plurality of axially extending grooves, said internal contact sleeve having an internal contact portion and an external flange stopper, said flange stopper being in contact with one longitudinal end of said external locking sleeve, said internal contact sleeve also having a fixing portion for fixing therewith said coaxial cable, a cylindrical insulating body having an internal opening and an external contact section received in said contact portion of said internal contact sleeve, an outer insulation sleeve having one part disposed about said external locking sleeve and another part about an intermediate portion of said internal contact sleeve such as to provide a gap between said another part of said outer insulation sleeve and said intermediate portion of said internal contact sleeve, said outer insulation sleeve having a longitudinal rear edge wall, a coil spring within said gap and disposed between said rear edge wall of said outer insulation sleeve and said flange stopper of said internal contact sleeve, said outer insulation sleeve having a locking opening for receiving said claw of said locking sleeve to thereby lock said locking sleeve and said outer insulation sleeve together whereby said locking sleeve and said outer insulation sleeve are unitarily longitudinally slidable relative to said internal contact sleeve in opposition to the bias of said coil spring,
• said inner installation means comprising a central contact pin having a contact portion and an external support portion disposed in said internal opening of said cylindrical insulating body of said outer installation means, said central contact pin having an internal passage for receiving the internal lead wire of said coaxial cable, said central contact pin having an inner longitudinal end, an insulation plate in contact with said inner longitudinal end of said central contact pin, said insulation plate having an internal opening through which said internal lead wire of said coaxial cable passes, said insulation plate also having a recess receiving a longitudinal end portion of the insulation body of said coaxial cable, and an inside sleeve extending into said fixing portion of said internal contact sleeve of said outer installation means and having a longitudinal end recess for receiving said installation plate, said inside sleeve having an internal passage receiving the insulation body and internal lead wire of said coaxial cable, the external conductor and the sheath of said coaxial cable being disposed between said inside sleeve and said fixing portion of said internal contact sleeve.
