Abstract

A clip (100) for surface mount termination includes a first conductor or retainer (102), a second conductor (104) and a dielectric element (106). The second conductor includes a center conductor contacting portion (144) defining a central bore (140) for receiving the center conductor (206) of a coaxial cable (202). The second conductor further includes a first flange (142) and a second flange (143) for mounting the clip to the surface (302) of a printed wiring board (300), thereby electrically terminating the cable at the printed wiring board.

Claims

1. A clip for surface mount termination of a cable to a surface of a printed wiring board, the clip comprising:

a first conductor having a securing portion sized for secure attachment to a portion of the cable; and

a second conductor having a first finger and a second finger extending from a contacting portion having a central bore shaped to contact a perimeter of a center conductor of a cable and for electrically contacting the center conductor proximate an end of the cable, the contacting portion and the first and the second finger retaining the center conductor in the central bore, and a flange portion integrally formed with at least one of the first finger and the second finger for electrical connection to the surface of the printed wiring board without extending through the surface of the printed wiring board.

2. A clip as recited in claim 1 wherein the first conductor further comprises a flange portion substantially coplanar with the flange portion of the second conductor for connection to the surface of the printed wiring board.

3. A clip as recited in claim 2 wherein the first conductor further comprises an electrically conductive portion for electrical connection between a jacket of the cable and the surface of the printed wiring board.

4. A clip as recited in claim 3 further comprising a dielectric element for electrically isolating the electrically conductive portion and the second conductor.

5. A clip for surface mount termination of a cable to a surface of a printed wiring board, the clip comprising:

a first conductor having a retainer sized to securely engage an outer surface of the cable and an axial arm extending along an axis of the cable from the retainer;

a second conductor having a first finger and a second finger extending from a contact portion having a central bore shaped to contact a perimeter of a center conductor of a cable and for electrically connecting the center conductor and the surface of the printed wiring board without deforming the center conductor, the contact portion and the first and the second finger retaining the center conductor in the central bore, and a flange integrally formed with at least one of the first finger and the second finger for electrical connection to the surface of the printed wiring board without extending through the surface of the printed wiring board; and

a dielectric element disposed between the axial arm and the second conductor.

6. A clip as recited in claim 5 wherein the retainer includes a flange portion for mechanical connection to the printed wiring board.

7. A clip as recited in claim 6 wherein the cable has a center conductor surrounded by a jacket and wherein the second conductor mechanically engages a portion of a center conductor segment from which the jacket has been removed and extends from the center conductor segment to contact the surface of the printed wiring board without deforming the center conductor.

8. A clip for surface mount termination of a cable to a surface of a printed wiring board, the cable including a jacket surrounding a center conductor, the clip comprising:

a first conductor including a first arm and a second arm extending from a base to form a channel sized for snap-fit retention of the jacket; and

a second conductor extending from the base, the second conductor having a center conductor contacting portion with an integrally formed attachment flange and a central bore shaped to contact a perimeter of a center conductor of a cable and shaped for electrical contact between a portion of the center conductor from which the jacket has been removed and the surface of the printed wiring board without penetrating the surface of the printed wiring board, the center conductor contact portion and the integrally formed attachment flange retaining the center conductor in the central bore.

9. A clip as recited in claim 8 wherein the second conductor further comprises a first finger and a second finger extending from the center conductor contacting portion, at least one of the first finger and the second finger extending to the attachment flange to contact the surface of the printed wiring board.

10. A clip as recited in claim 9 wherein the first finger and the second finger include integrally formed respective finger flange portions, at least one of the finger flange portions forming the attachment flange for attachment to the surface of the printed wiring board.

11. A clip as recited in claim 10 wherein the first finger and the second finger include respective finger flange portions for attachment to the surface of the printed wiring board.

12. A cable assembly comprising:

a coaxial cable having a predetermined length, the coaxial cable including a jacket surrounding a center conductor, a portion of the jacket being removed to expose a center conductor segment at one end of the coaxial cable;

a clip including

a first conductor sized to securely engage an outer surface of the jacket;

an arm extending from the first conductor along an axis of the coaxial cable; and

a second conductor, having a center conductor contacting portion with an integrally formed attachment flange and a central bore, shaped to contact a perimeter of a center conductor of a cable, the second conductor extending from the arm for electrically connecting the center conductor segment and a surface of a printed wiring board without deforming the center conductor and without-penetrating the surface of the printed wiring board, the center conductor contacting portion and the integrally formed attachment flange retaining the center conductor in the central bore.

13. A cable assembly as recited in claim 12 wherein the second conductor further comprises a first finger and a second finger extending from the center conductor contacting portion, at least one of the first finger and the second finger extending to the attachment flange to contact the surface of the printed wiring board.

14. A cable assembly as recited in claim 13 wherein the first finger and the second finger include integrally formed respective finger flange portions for attachment to the surface of the printed wiring board at least one of the finger flange portions forming the attachment flange.

15. A cable assembly as recited in claim 14 wherein the first conductor includes a base and a first arm and a second arm extending from the base to form a channel sized for snap-fit retention of the jacket, the first arm and the second arm each including a respective arm flange portion substantially coplanar with the respective finger flange portions for attachment to the surface of the printed wiring board.
