Abstract

The invention relatives to male and female coaxial cable connector sub-assemblies utilizing a universal fitting crimped to the end of a coaxial cable and threadably attached to a subassembly. Each sub-assembly has a central dielectric plug pressfitted in place. A center contact or a center contact receptacle is pressed into the plug and maintained by a protecting skirt which bites into the dielectric plug. The center contact or receptacle receives a projecting portion of the coaxial cable center conductor when the universal fitting is threadably attached. In other preferred embodiments, the center contact and the corresponding center contact receptacle are each laterally supported by another dielectric plug which provides adjustment for impedance mismatch entirely through the connector subassembly.

Claims

1. A coaxial connector sub-assembly, comprising:

a universal fitting, a coaxial cable crimped to said universal fitting, a coupling member receiving said fitting, a web internally of said coupling member, a first dielectric plug press-fit within said web, said first plug including an outer flange portion in registration on said web, a sleeve of conductive material press-fit in said first plug, an annular inclined barb on said sleeve and engaged in said first plug, a receptacle at one end of said sleeve and internally of said first plug and receiving the center conductor of said cable therein, a center contact means at the other end of said sleeve and protruding externally of said first plug, said center contact means in spaced relationship from and internAlly within said coupling member, and a second dielectric plug press-fit internally of said coupling member and receiving said center contact means therein, a portion of said first dielectric plug protruding from said web and received internally of said second dielectric plug.

2. A coaxial connector sub-assembly, comprising:

a universal fitting, a coaxial cable crimped to said universal fitting, a coupling member receiving said fitting, a web internally of said coupling member, a first dielectric plug press-fit within said web, said first plug including an outer flange portion in registration on said web, a sleeve of conductive material press-fit in said first plug, an annular inclined barb on said sleeve and engaged in said first plug, a receptacle at one end of said sleeve and internally of said first plug and receiving the center conductor of said cable therein, a center contact means at the other end of said sleeve and protruding externally of said first plug, said center contact means in spaced relationship from and internally within said coupling member, said universal fitting being generally cylindrical and externally threaded, said coupling member being complimentary threaded and threadably receiving said universal fitting therein, and an enlarged flange portion provided on said universal fitting for external engagement on said coupling member.

3. The structure as recited in claim 2, wherein, said universal fitting is fabricated from an electrically conductive material, said coaxial cable is received within said universal fitting, and a deformable ferrule of conducting material is wedgingly inserted between said coaxial cable and said universal fitting in order to crimp said coaxial cable to said universal fitting.

4. The structure as recited in claim 3, wherein, said first plug includes an enlarged outer collar portion protruding from said web, and said web is received between and engaged by said flange portion and said collar portion.

5. The structure as recited in claim 4, wherein said flange portion is compressible to allow insertion of said flange portion through said web, and said flange portion is expandable after compression in order that said web is received between and engaged by said flange portion and said collar portion.

6. The structure as recited in claim 2, and further including:

an aperture provided in said coupling member for insertion therein of a torque rod for applying a selected torque level to the fitting within the coupling member.
