Abstract

A coaxial connector is disclosed for terminating a coaxial transmission line. The connector includes a tubular spring element, comprising a cylindrical body having a plurality of reversely formed leaf spring fingers annularly spaced, and projecting forwardly therefrom. The spring fingers are intended for positionment within a tubular plug shell, and are engaged and compressed upon insertion of a jack body therebetween for retaining and electrically contacting the jack body.

Claims

1. Improved retention means for a connector tubular plug shell which matingly receives a tubular jack body in a forward end, the improvement comprising:

a tubular spring element seated within a forward end of said tubular plug shell, said spring element comprising forward projecting inner leaf springs defining a passageway therebetween for receiving said jack body with interference, and reversely formed outer leaf springs having forward ends integrally joined to respective forward ends of said inner leaf springs, said inner and outer leaf springs being normally spaced apart, whereby upon insertion of said jack body into said passageway between said inner leaf springs, said inner and outer leaf springs compress against an interior wall of said tubular plug shell to exert radial retention forces on said jack body.

2. Improved retention means as set forth in claim 1, wherein said spring element further comprises a solid cylindrical portion, said inner leaf springs comprising integral extensions of said solid portion.

3. A connector as set forth in claim 1, wherein said cylindrical plug shell having a forward end inwardly formed to protect said integrally joined forward ends of said leaf springs.

4. Improved retention means as set forth in claim 1, wherein each of said inner leaf springs has inwardly directed, transversely extending ridge means located intermediate the ends thereof, said ridge means being adapted to project into complementary recess means in said jack body upon mating engagement between said plug and jack.

5. Improved retention means as set forth in claim 4, wherein each said outer leaf springs has a substantially inverted V-shaped profile, with an apex of said V-shape being longitudinally located to coincide with said ridge means respectively of said inner leaf springs, and said apex comprising an engagement point between said outer leaf springs and an interior wall of said plug shell.

6. Improved retention means for a connector tubular plug shell which matingly receives a tubular jack body in a forward end, the improvement comprising:

tubular spring element seated within a forward end of said tubular plug shell, said spring element comprising a solid cylindrical portion having forward projecting cantilever inner leaf springs defining a passageway therebetween for receiving said jack body with interference, each of said inner leaf springs having inwardly directed, transversely extending ridge means located intermediate the ends thereof, said ridge means being adapted to project into complementary recess means in said jack body upon mating engagement between said plug and jack;

said spring element further comprising reversely formed outer leaf springs having forward ends integrally joined respectively to forward ends of said inner leaf springs, said inner and outer leaf springs being substantially parallel and spaced apart, and each of said outer leaf springs having a substantially inverted V-shaped profile, with apex means of said V-shaped profile being longitudinally located to coincide with said ridge means respectively of said inner leaf springs, whereby upon insertion of said jack body into said passageway between said inner leaf springs, said inner and outer leaf springs compress, as apex means of said outer leaf springs engage an interior wall of said tubular plug shell.

7. Improved retention means as set forth in claim 6, wherein said cylindrical plug shell having a forward end inwardly formed to protect said integrally joined forward ends of said leaf springs.

8. A coaxial connector for terminating a coaxial cable comprising:

contact means for terminating the center conductor of said cable;

dielectric means for insulating said contact means;

tubular shell means for terminating the outer conductor of said cable and receiving said dielectric and contact means therein, said shell means comprising a forward cylindrical portion having an interior wall defining an axial passageway therebetween; and

a tubular spring element seated within said cylindrical shell means portion and having a plurality of forward projecting spring finger means defining a passageway therebetween for receiving a tubular jack body with interference;

each of said spring finger means comprising an inner leaf spring means and a free extending reversely formed outer leaf spring means, forward ends of said inner leaf spring means and said outer leaf spring means integrally joined, said spring finger means being normally spaced apart and parallel whereby, upon insertion of said tubular jack body between said inner leaf spring means, said leaf spring means compress against said interior wall of said cylindrical shell portion to exert radial retention forces on said jack body.

9. A connector as set forth in claim 8, wherein said tubular spring element further comprises a solid cylindrical portion, said inner leaf spring means comprising integral extensions of said solid cylindrical portion.

10. A connector as set forth in claim 8, wherein said forward cylindrical shell portion has a forward end inwardly formed forward of said integrally joined forward ends of said leaf spring means.

11. A connector as set forth in claim 8, wherein each of said inner leaf spring means has inwardly directed, transversely extending, ridge means located intermediate the ends thereof.

12. A connector as set forth in claim 11, wherein each said outer leaf spring means has a generally inverted V-shaped profile, with an apex of said inverted V-shape being longitudinally located to coincide with said ridge means of said inner leaf spring means, and said apex engaging said interior wall of said cylindrical shell portion.

13. A coaxial connector for matable engagement with a tubular jack member, comprising:

tubular shell means having tubular element means seated therein;

leaf spring means extending outwardly from said tubular element means along said tubular shell means substantially parallel to an axis of the coaxial connector and defining a lead-in and receiving area into which a forward end of the tubular jack member is to be received; and

V-shaped leaf spring means respectively connected to said leaf spring means for applying radial spring action to said leaf spring means as the forward end of the tubular jack member is received in said receiving area thereby urging said leaf spring means into electrical and mechanical connection with the forward end of the tubular jack member.

14. A coaxial connector as set forth in claim 13 wherein a forward end of said tubular shell means is rolled in covering forward ends of said leaf spring means to protect them and defining part of the lead-in for the forward end of the tubular jack member.

15. A coaxial connector as set forth in claim 13 wherein said leaf spring means include detent ridge means for engagement with an annular recess in the forward end of the tubular jack member.

16. A coaxial connector as set forth in claim 15 wherein an apex of said V-shaped leaf spring means engages said tubular shell means in alignment with said detent ridge means.
