Coaxial cable connector

1. A coaxial cable connector for mechanically and electrically connecting a coaxial cable to an electronic apparatus, the coaxial cable including a central conductor, an insulator surrounding the central conductor, a foil layer surrounding the insulator, at least one layer of braided conducting sheath surrounding the foil layer, and a jacket surrounding the at least one braided conducting sheath; the coaxial cable connector comprising:

a standard adapter including a hollow inner sleeve and a hollow outer sleeve coaxial with the inner sleeve; and

a mini adapter including an inner member mechanically and electrically associated with the central conductor of the coaxial cable; a cylindrical housing having a first tubular end portion adapted to receive the central conductor, the insulator, and the foil layer of the coaxial cable therein, and a second tubular end portion adapted to receive the at least one braided conducting sheath and the jacket of the coaxial cable therein; the first tubular end portion being externally formed with a plurality of elastic hooking portions correspondingly located around the inner member, and internally provided with a contact spring for mechanically associating with the foil layer of the coaxial cable;

whereby when the mini adapter is fully inserted into the standard adapter to associate therewith, the elastic hooking portions are compressed and radially inward moved by the inner sleeve of the standard adapter, urging the inner member of the mini adapter to tightly contact and clamp the central conductor of the coaxial cable, and the contact spring is also compressed by the inner sleeve of the standard adapter to mechanically and electrically contact and associate with the foil layer of the coaxial cable.

2. The coaxial cable connector as claimed in claim 1 , wherein the second tubular end portion of the mini adapter is formed on a wall thereof with a second annular recess portion, whereby when an axial insertion force is applied to the round sleeve against the outer sleeve, the second annular recess portion is bent to engage with the jacket of the coaxial cable.

3. The coaxial cable connector as claimed in claim 1 , wherein the inner member of the mini adapter includes a finger clamp, which is located in the first tubular end portion corresponding to the elastic hooking portions and adapted to clamp and hold the central conductor of the coaxial cable in place.

4. The coaxial cable connector as claimed in claim 1 , wherein the mini adapter further includes a round sleeve externally and coaxially mounted around the second tubular end portion.

5. The coaxial cable connector as claimed in claim 4 , wherein the outer sleeve of the standard adapter is formed of at least one first annular recess portion, whereby when an axial insertion force is applied to the round sleeve against the outer sleeve, the at least one first annular recess portion is bent to engage with the round sleeve.

6. The coaxial cable connector as claimed in claim 4 , wherein the round sleeve has a radially outward extended flange, which is brought to contact with and push the outer sleeve forward when the round sleeve is subjected to an axial insertion force against the outer sleeve.

7. The coaxial cable connector as claimed in claim 4 , further comprising a conducting element located between and electrically connected to the round sleeve and the contact spring.

8. The coaxial cable connector as claimed in claim 1 , wherein the first tubular end portion is provided around an area near the second tubular end portion with a plurality of long slots.

9. The coaxial cable connector as claimed in claim 8 , wherein the contact spring includes a ring portion configured for fitting in the second tubular end portion, and a plurality of contact strips integrally formed with and extended from the ring portion; and the contact strips being located in the long slots on the first tubular end portion for clamping the foil layer of the coaxial cable.
