Abstract

A socket includes a housing that supports terminal bricks that can contain one or more terminals. The terminal bricks are inserted into apertures in the housing. The location of the terminal bricks can be adjusted separate from a side of the housing, thus providing the potential to improve coplanarity of the terminals in the socket.

Claims

1. A socket, comprising:

a housing with a first and second side opposite the first side and a first, a second and a third aperture extending from the first side to the second side, the first and second side spaced apart a first distance and each of the apertures having a perimeter; and

a first terminal brick, a second terminal brick and a third terminal brick inserted, respectively, into the first, second and third apertures, each terminal brick including a support block with a third side and a fourth side and an outer surface that extends between the third and fourth side, the third and fourth side being spaced apart a second distance that is substantially less than the first distance so that the support block is fully enclosed by the housing on the outer surface and at least one pair of terminals supported by the support block, wherein the first terminal brick has less terminals than both the second terminal brick and the third terminal brick and each of the first, second and third terminal bricks has an even number of terminals, wherein the terminal bricks are inserted into the apertures to provide for a desired level of coplanarity and wherein each of the terminals includes a tail extending from the fourth side and an arm extending from the third side and extending out from the aperture on the first side and a body supported by the support block, the arm supporting a contact, wherein the arm extends in a transverse direction with respect to the aperture such that the contact extends toward and is more closely aligned with a body of an adjacent terminal and the tail extends from the support block in a manner such that the tail is aligned inside an area defined by the perimeter, wherein the bodies of the two terminals that form each of the pairs of terminals are offset toward each other compared to the tails of the two terminals, wherein the two terminals that form each of the pairs of terminals are configured so that they are closer to each other than either terminal is to an adjacent terminal along a substantial portion of a length of the arms.

2. The socket of claim 1, further comprising a shield configured to provide electrical isolation between a first pair of terminals and a second pair of terminals.

3. The socket of claim 1, wherein one of the housing and a terminal brick includes a conductive layer that is configured to decrease cross-talk between two pairs of terminals.

4. The socket of claim 3, wherein the housing is partially formed of a conductive plastic.

5. The socket of claim 3, wherein one side of a terminal brick includes a conductive layer.

6. The socket of claim 3, wherein both the housing and the terminal brick includes conductive layers that collective provides cross-talk shielding between a first and second pair of terminals.

7. A socket, comprising:

a housing with a first side and a second side and a first aperture and a second aperture and a third aperture extending from the first side to the second side; and

a first terminal brick, a second terminal brick and a third terminal brick inserted, respectively, into the first, second and third apertures, each terminal brick including a support block that is completely positioned within the aperture between the first and second side and that supports a first terminal and a second terminal that form a terminal pair, wherein the terminal bricks are inserted into the apertures to provide for a desired level of coplanarity and wherein each of the terminals includes a tail extending from the second side, a body supported by the support block and an arm extending from the aperture on the first side, the arm supporting a contact, wherein the contacts of the first and second terminals are spaced apart and the arms of the first and second terminals are closer together than the contacts along a substantial portion of the arms, wherein the third terminal brick has more terminal pairs than the second terminal brick and the second terminal brick has more terminal pairs than the first terminal brick and each of the first, second and third terminal bricks has an even number of terminals.

8. The socket of claim 7, wherein the arm extends transversely to a direction aligned with the aperture such that the contact is more closely aligned with a body of an adjacent terminal than the body of the supporting terminal.

9. The socket of claim 7, wherein the terminal bricks are configured to be inserted into the apertures with an interference fit.

10. The socket of claim 9, wherein the housing does not include a stop feature.

11. The socket of claim 7, wherein one of the housing and a terminal brick includes a conductive layer that is configured to decrease cross-talk between two pairs of terminals.

12. The socket of claim 7, wherein a portion of the housing is formed of a conductive plastic.

13. The socket of claim 7, wherein both the housing and a terminal brick includes a conductive layer that is configured to decrease cross-talk between two pairs of terminals.

14. The socket of claim 7, wherein the tails are configured to be press-fit into a via.

15. The socket of claim 7, wherein a substantial portion of the body of the first terminal is positioned closer to the body of the second terminal than it is to the body of any adjacent terminal.

16. The socket of claim 7, wherein each terminal brick further supports a third terminal and a fourth terminal, the third and fourth terminals each having a tail extending from the second side, a body supported by the support block and an arm extending from the aperture on the first side, the arm supporting a contact, wherein the first and second terminals are configured to provide a first differential pair and the third and fourth terminals are configured to provide a second differential pair.
