Abstract

High-speed connectors that save space in an electronic device, are simple to connect, and are readily manufactured. One example can provide a high-speed connector having high-speed connections. The high-speed connections can be integrated with low-speed connections in a board-to-board structure to save space in an electronic device. An example can provide high-speed connections that are simple to connect. The board-to-board structure can include a board-to-board plug, where each high-speed connection includes a high-speed contact having a lateral portion. The lateral portion can include right-angle tabs to guide a central conductor of a coaxial cable. The central conductor of each coaxial cable can be soldered to a corresponding lateral portion. Ground contacts for the board-to-board plug can include crimping portions to connect to an outer shield of each coaxial cable. These high-speed connectors can be readily manufactured by utilizing stamped contacts and molded housings.

First claim

What is claimed is:

1. A high-speed connector comprising:
a board-to-board receptacle comprising:
a housing including a recess defining a first raised central portion, a second raised portion, a third raised portion, and a raised outer portion;
a first plurality of low-speed contacts in the recess, each on a first edge of the first raised central portion and a first edge of the raised outer portion;
a second plurality of low-speed contacts in the recess, each on a second edge of the first raised central portion and a second edge of the raised outer portion;
a first high-speed contact on the second raised portion;
a second high-speed contact on the third raised portion; and
a plurality of ground contacts on the first raised central portion; and

a board-to-board plug comprising:
a housing including a raised outer portion around a first recess, a second recess, and a third recess, where the raised outer portion is arranged to fit in the recess of the board-to-board receptacle, the first recess is arranged to accept the first raised central portion of the board-to-board receptacle, the second recess is arranged to accept the second raised portion of the board-to-board receptacle, and the third recess is arranged to accept the third raised portion of the board-to-board receptacle;
a first plurality of low-speed contacts on a first side of the raised outer portion;
a second plurality of low-speed contacts on a second side of the raised outer portion;
a first high-speed contact in the second recess; and
a second high-speed contact in the third recess.

2. The high-speed connector of claim 1 wherein the plurality of ground contacts on the first raised central portion of the board-to-board receptacle comprises a first ground contact between the first high-speed contact and the first plurality of low-speed contacts and a second ground contact between the second high-speed contact and the first plurality of low-speed contacts.

3. The high-speed connector of claim 2 further comprising a third ground contact on three sides of the recess and around the first high-speed contact, and a fourth ground contact on three sides of the recess and around the second high-speed contact.

4. The high-speed connector of claim 3 wherein the first ground contact and the third ground contact shield the first high-speed contact and the second ground contact and the fourth ground contact shield the second high-speed contact.

5. The high-speed connector of claim 4 wherein when the board-to-board receptacle is mated with the board-to-board plug, the first high-speed contact on the second raised portion physically and electrically contacts the first high-speed contact in the second recess and the second high-speed contact on the third raised portion physically and electrically contacts the second high-speed contact in the third recess.

6. The high-speed connector of claim 5 wherein the housing for the board-to-board receptacle is insert molded around the low-speed contacts, high-speed contacts, and ground contacts.

7. The high-speed connector of claim 6 wherein the housing for the board-to-board plug is insert molded around the low-speed contacts and high-speed contacts, and the ground contacts are inserted into the housing.

8. A high-speed connector comprising:
a board-to-board receptacle comprising:
a housing including a recess defining a first raised central portion, a second raised portion, a third raised portion, and a raised outer portion;
a first plurality of low-speed contacts, each having a first exposed surface on a first edge of the first raised central portion and a second exposed surface on a first edge of the raised outer portion;
a second plurality of low-speed contacts, each having a first exposed surface on a second edge of the first raised central portion and a second exposed surface on a second edge of the raised outer portion;
a first high-speed contact on the second raised portion;
a second high-speed contact on the third raised portion; and
a first ground contact on a third edge of the first raised central portion;
a second ground contact on a fourth edge of the first raised central portion; and

a board-to-board plug comprising:
a housing including a raised outer portion around a first recess, a second recess, and a third recess, where the raised outer portion is arranged to fit in the recess of the board-to-board receptacle, the first recess is arranged to accept the first raised central portion of the board-to-board receptacle, the second recess is arranged to accept the second raised portion of the board-to-board receptacle, and the third recess is arranged to accept the third raised portion of the board-to-board receptacle;
a first plurality of low-speed contacts on a first side of the raised outer portion;
a second plurality of low-speed contacts on a second side of the raised outer portion;
a first high-speed contact in the second recess; and
a second high-speed contact in the third recess.

9. The high-speed connector of claim 8 wherein the first ground contact is between the first plurality of low-speed contacts and the first high-speed contact and between the second plurality of low-speed contacts and the first high-speed contact.

10. The high-speed connector of claim 9 wherein the second ground contact is between the first plurality of low-speed contacts and the second high-speed contact and between the second plurality of low-speed contacts and the second high-speed contact.

11. The high-speed connector of claim 10 further comprising a third ground contact on three sides of the recess and around the first high-speed contact, and a fourth ground contact on three sides of the recess and around the second high-speed contact.

12. The high-speed connector of claim 11 wherein the first ground contact and the third ground contact shield the first high-speed contact and the second ground contact and the fourth ground contact shield the second high-speed contact.

13. The high-speed connector of claim 12 wherein when the board-to-board receptacle is mated with the board-to-board plug, the first high-speed contact on the second raised portion physically and electrically contacts the first high-speed contact in the second recess and the second high-speed contact on the third raised portion physically and electrically contacts the second high-speed contact in the third recess.

14. The high-speed connector of claim 13 wherein the housing for the board-to-board receptacle is insert molded around the low-speed contacts, high-speed contacts, and ground contacts.

15. The high-speed connector of claim 14 wherein the housing for the board-to-board plug is insert molded around the low-speed contacts and high-speed contacts, and the ground contacts are inserted into the housing.

16. A high-speed connector comprising:
a board-to-board receptacle comprising:
a housing including a recess defining a first raised central portion, a second raised portion, a third raised portion, and a raised outer portion;
a plurality of low-speed contacts supported by the first raised central portion;
a first high-speed contact supported by the second raised portion;
first shielding around the first high-speed contact comprising a first ground contact supported by the first raised central portion and a second ground contact around the second raised portion and supported by the raised outer portion;
a second high-speed contact supported by third raised portion; and
