Abstract

A coaxial connector (1) to be connected to a coaxial cable (8) includes a nut (2), a sleeve (3), a seal (4), a clamp (5) and a ferrule (6). The coaxial cable includes a cable center conductor (80), a cable dielectric layer (81), a cable outer conductor (82) and a cable jacket (83). The sleeve includes a tubular portion (31) inserted between the cable dielectric layer and the cable outer conductor, and an outer flange (32) fixed by the nut. The clamp has a clamp portion (50) enclosing the sleeve and a serrate inner wall (53). The ferrule includes an inner surface slidingly engaged the cable jacket and an outer surface has a plurality of saw-teeth (65) for matching with the serrate inner wall of the clamp.

Claims

1. A coaxial connector adapted to be connected to a coaxial cable comprising a cable center conductor, a cable dielectric layer, a cable outer conductor and a cable jacket, the coaxial connector comprising:

a nut;

a sleeve being partially received in the nut and having a tubular portion for electrically connecting with the cable outer conductor;

a clamp substantially spatially surrounding the sleeve and having a serrate wall; and

a ferrule inserted in the clamp and having a plurality of saw-teeth engaged with the serrate wall of the clamp for securely fixing the coaxial cable to the sleeve.

2. The coaxial connector as claimed in claim 1, wherein the nut has a plurality of screw threads formed on the inner surface thereof.

3. The coaxial connector as claimed in claim 1, further comprising a seal between the nut and the clamp.

4. The coaxial connector as claimed in claim 1, wherein the clamp comprises a slant inner wall for inwardly pressing the ferrule when the clamp is inserted into the clamp.

5. The coaxial connector as claimed in claim 1, wherein the ferrule comprises a flat and smooth inner surface.

6. The coaxial connector as claimed in claim 1, wherein the ferrule is made of deformable material.

7. A connector assembly comprising:

a coaxial cable comprising a cable center conductor, a cable dielectric layer, a cable outer conductor and a cable jacket;

a nut;

a sleeve fixed by the nut and having a tubular portion for inserting between the cable dielectric layer and the cable outer conductor;

a clamp having a clamp portion enclosing the sleeve, the clamp and the sleeve forming an annular cavity; and

a ferrule adapted for axially sliding insertion into the annular cavity.

8. The connector assembly as claimed in claim 7, wherein the clamp comprises a slant inner wall in a middle portion thereof and a serrate inner wall in a rear portion thereof.

9. The connector assembly as claimed in claim 7, wherein the ferrule comprises an inner surface and an outer surface, the inner surface slidingly engaging the cable jacket, the outer surface having a plurality of saw-teeth matching with the serrate inner wall of the clamp.

10. The connector assembly as claimed in claim 7, wherein the ferrule is made of deformable material.

11. A coaxial cable connector assembly comprising:

a coaxial cable defining inner and outer coaxial structures commonly extending along a first direction;

a sleeve extending along a second direction opposite to said first direction and having a front portion tightly sandwiched between said inner and outer structures of a front section of the cable;

a tubular clamp spatially and coaxially surrounding said sleeve and extending along said second direction; and

a tubular ferrule coaxially surrounding the cable and extending in said first direction;

wherein

a front portion of said ferrule is radially located between the clamp and the sleeve.

12. The coaxial cable connector assembly as claimed in claim 11, wherein said ferrule is sandwiched between an inner face of the clamp and an outer face of the outer structure of the cable.

13. The coaxial cable connector assembly as claimed in claim 12, wherein said outer structure of the front section of the cable is tightly sandwiched between the sleeve and the ferrule.

14. The coaxial cable connector assembly as claimed in claim 11, wherein a front end the outer structure of the cable abuts against at least one of clamp and the sleeve in said first direction so as to assure no further mutual relative movement between the cable and the sleeve.

15. The coaxial cable connector assembly as claimed in claim 11, wherein said ferrule is moveable relative to the clamp in the first direction for increasing tightness among the cable, the ferrule and the sleeve.
