Abstract

A connector for connecting a coaxial cable to a printed circuit board includes a support portion that receives an end of the coaxial cable within a hollow structure thereof so that an exposed outer conductor of the coaxial cable is connected to an interior surface of a side wall of the hollow structure and so that the coaxial cable extends within the support portion perpendicular to the printed circuit board. The connector further includes an engagement portion that is connected to the support portion and configured to fix the connector to a first side of the printed circuit board, where the engagement portion is mounted above a via hole in the printed circuit board.

First claim

That which is claimed is:

1. A connector configured for connecting a coaxial cable to a printed circuit board, the coaxial cable having an exposed outer conductor on one end portion thereof and having an exposed inner conductor that extends beyond the exposed outer conductor, the connector comprising:
a support portion, which includes a hollow structure having a side wall, wherein the support portion is configured to receive one end portion of the coaxial cable within the hollow structure so that the exposed outer conductor is mechanically and electrically connected to an interior surface of the side wall and so that the coaxial cable extends within the support portion perpendicular to the printed circuit board; and
an engagement portion, which is connected to the support portion and configured to affix the connector to a first side of the printed circuit board, wherein the engagement portion is mounted above a via hole in the printed circuit board,
wherein the engagement portion of the connector is configured to reside closer to the printed circuit board than the support portion of the connector, and
wherein the connector has a unitary body with the support portion merging into the engagement portion, and wherein the engagement portion has a height in a height dimension aligned with a thickness of the printed circuit board, that is less than a height of the support portion.

2. The connector according to claim 1 , wherein the hollow structure is aligned with the via hole, wherein the engagement portion terminates at and/or above the first side of the printed circuit board, and wherein the engagement portion is attached to the first side of the printed circuit board.

3. The connector according to claim 2 , wherein the exposed outer conductor extends into and terminates inside the hollow structure, and wherein the exposed inner conductor extends through a portion of the hollow structure, through the engagement portion and through the via hole and is electrically connected to a metal pattern on a second side of the printed circuit board that opposes the first side of the printed circuit board.

4. The connector according to claim 1 , wherein an electrical conductor is mounted within the via hole and extends into the support portion of the connector, wherein the exposed inner conductor is connected to the electrical conductor, which is further connected to a metal pattern on the first side or an opposite second side of the printed circuit board.

5. The connector of claim 4 , wherein the exposed inner conductor terminates above the printed circuit board inside the support portion and inside the electrical conductor.

6. The connector according to claim 1 , wherein the engagement portion is electrically connected to the printed circuit board.

7. The connector according to claim 1 , wherein the engagement portion includes one or more flanges that extend radially outward from the side wall of the support portion, and wherein the flanges are circumferentially spaced apart from one another by gaps and reside against the first side of the printed circuit board.

8. The connector according to claim 1 , wherein the connector connects the coaxial cable to a side of the printed circuit board that is adjacent a ground element, and the engagement portion is configured for electrical connection with the ground element.

9. The connector of claim 1 , further comprising a first bond pad on the first side of the printed circuit board surrounding the via and coupled to the engagement portion of the connector and a second bond pad on an opposing side of the printed circuit board surrounding the via and coupled to a metal pattern.

10. A multi-port connector that is configured to connect a plurality of coaxial cables to a printed circuit board, the plurality of coaxial cables each having an exposed outer conductor exposed on one end thereof and an exposed inner conductor that extends beyond the exposed outer conductor, the multi-port connector comprising:
a plurality of support portions that each include a hollow structure having a side wall, wherein each support portion is configured to receive an end of a respective one of the coaxial cables so that the respective exposed outer conductor is mechanically and electrically connected to an interior surface of the respective side walls such that corresponding coaxial cables extend within the respective support portions perpendicular to the printed circuit board; and
an engagement portion that is connected to the plurality of support portions and configured to affix the multi-port connector to a first side of the printed circuit board.

11. The multi-port connector according to claim 10 , wherein the plurality of support portions are integrated on the engagement portion at least in one row.

12. The multi-port connector according to claim 10 , wherein the printed circuit board includes a plurality of via holes, and each of the hollow structures is configured to surround a respective one of the via holes, wherein the engagement portion terminates at and/or above the first side of the printed circuit board, and wherein the engagement portion is attached to the first side of the printed circuit board.

13. The multi-port connector according to claim 12 , wherein the exposed outer conductor of a first of the coaxial cables is retained within and terminates inside a first of the hollow structures, and the exposed inner conductor of the first of the coaxial cables extends through a portion of the first of the hollow structures and a first of the via holes and is electrically connected to a trace of a metal pattern on a second side of the printed circuit board that opposes the first side of the printed circuit board.

14. The multi-port connector according to claim 10 , wherein an electrical conductor is disposed in a first of the via holes and extends into a first of the hollow structures, wherein the exposed inner conductor is connected to the electrical conductor and terminates inside the first of the hollow structures, and wherein the electrical conductor is further connected to a trace of a metal pattern on the first side or an opposite second side of the printed circuit board.

15. The multi-port connector according to claim 10 , wherein the exposed outer conductor of a first of the coaxial cables is soldered to the side wall of the support portion.

16. The multi-port connector according to claim 10 , wherein the engagement portion is located closer to the printed circuit board than the support portion and includes one or more flanges that extend radially outward from the side wall of the support portion, and wherein the one or more flanges are attached to the first side of the printed circuit board.

17. The multi-port connector according to claim 16 , wherein the printed circuit board includes a bond pad, and one or more of the flanges is soldered to the bond pad.

18. The multi-port connector according to claim 10 , wherein the multi-port connector connects a first of the coaxial cables to a side of the printed circuit board that is adjacent a ground element, and the engagement portion is configured for electrical connection with the ground element.

19. The multi-port connector according to claim 18 , wherein the engagement portion is configured to engage the ground element of the printed circuit board by soldering, plugging, or additional mechanical structure.
