Abstract

An RF connector includes: a first printed circuit board with mounted devices; a first bridge assembly mounted adjacent to one side of the first board and including signal transmission pins; a second printed circuit board spaced apart from the first board; connection terminals adjacent to the second board contacting surfaces of the signal pins; a push bar applying force to maintain contact between the pins and terminals; and a metal shielding plate fixed to the push bar and second board, shielding portions of both. Shielding walls may be disposed between adjacent signal pins, improving isolation. The push bar has a wedge shape, creating a bending unit in the transmission pins according to lever principles. The connector transmits RF signals, power, and digital signals on the same plane, reducing size and cost while effectively processing signals in various frequency bands without expensive multi-connectors.

First claim

What is claimed is:

a plurality of connection terminals disposed at an area adjacent to at least one side of the second printed circuit board so as to be in contact with at least one surface of the plurality of first signal transmission pins;
a first push bar configured to apply a force to at least one surface of the plurality of first signal transmission pins to keep the contact between the plurality of first signal transmission pins and the plurality of connection terminals; and
a first metal shielding plate fixed to the first push bar and the second printed circuit board, and configured to shield at least some of the second printed circuit board and the first push bar.

2. The RF connector of claim 1 , comprising:
a plurality of shielding walls disposed between two first signal transmission pins adjacent to each other,
wherein the plurality of shielding walls is in contact with grounds of the first printed circuit board and the second printed circuit board.

3. The RF connector of claim 1 , wherein the plurality of first signal transmission pins is assembled to the first bridge assembly at an equal interval.

4. The RF connector of claim 1 , wherein the plurality of first signal transmission pins corresponds to the plurality of connection terminals, respectively, and
the plurality of first signal transmission pins is in contact with one surface of the plurality of connection terminals to be overlapped.

5. The RF connector of claim 1 , wherein a protruding unit which is in contact with the plurality of connection terminals is formed on one surface of each of the plurality of first signal transmission pins.

6. The RF connector of claim 5 , wherein the first push bar is configured to apply force to the other surface of the plurality of first signal transmission pins.

7. The RF connector of claim 6 , wherein the first push bar has a wedge shape, and a wedge-shaped vertex is positioned between the first printed circuit board and the second printed circuit board.

8. The RF connector of claim 7 , wherein the plurality of first signal transmission pins forms a bending unit between the first printed circuit board and the second printed circuit board.

9. The RF connector of claim 1 , wherein the plurality of first signal transmission pins transmits an RF signal, power, and a digital signal.

10. The RF connector of claim 1 , wherein the plurality of connection terminals is configured as a pad type.

11. The RF connector of claim 1 , wherein the first push bar is made of a plastic material.

12. The RF connector of claim 1 , wherein the first printed circuit board is an amp board, and
the second printed circuit board is a digital board.

13. The RF connector of claim 1 , further comprising:
a third printed circuit board disposed to be spaced apart from an opposite side where the first printed circuit board is positioned based on the second printed circuit board, and mounted with a plurality of devices;
a second bridge assembly mounted on an area adjacent to at least one side of the third printed circuit board and including a plurality of second signal transmission pins;
a second push bar configured to apply force to at least one surface of the plurality of second signal transmission pins to keep the contact between the plurality of second signal transmission pins and the plurality of connection terminals; and
a second metal shielding plate fixed to the second push bar and the second printed circuit board, and configured to shield at least some of the second printed circuit board and the second push bar.

14. The RF connector of claim 13 , wherein the third printed circuit board is the amp board.
