Abstract

An assembly for conducting an electronic signal. The assembly includes a substrate and an electronic cable. The substrate has distinct first and second regions to enable connection to first and second circuit boards, respectively. First and second through-holes are formed in the substrate in the first and second regions, respectively. The electronic cable is disposed within the first through-hole and extends out of the first through hole, adjacent the substrate and into the second through-hole.

Claims

1. An electronic assembly comprising:

a substrate having first and second surfaces;

a first through-hole extending through the substrate from a first opening at the first surface to a second opening at the second surface;

a first projecting pin extending through the first opening into the first through-hole and terminating at a first pin terminal secured within the first through-hole;

a first cable that includes a first conductive member with first and second flexible end sections, the first flexible end section terminating at a first cable terminal, the first flexible end section extending through the second opening and including a spring structure that includes first and second bends within the first through-hole, and wherein the first cable terminal is forcibly engaged against the first pin terminal by a first force; and

a capture member disposed adjacent to the second surface of the substrate,

wherein the capture member secures the first cable at a predetermined position relative to the substrate,

wherein the capture member exerts a second force on the first cable urging the first cable toward the first through-hole, at least some of the second force being transmitted from through the first cable and into the pin terminal in the form of the first force, and

wherein the capture member is secured in a fixed position relative to the substrate.

2. The assembly of claim 1, wherein the through-hole is a non-plated through-hole.

3. The assembly of claim 1, wherein the first force is transmitted through the first flexible end section to maintain the forcible engagement between the first cable terminal and the first pin terminal.

4. The assembly of claim 3, wherein the first flexible end section comprises a deformation as a result of the first force.

5. The assembly of claim 4, wherein the deformation in the first flexible end section includes one of the first and second bends of the first flexible end section.

6. The assembly of claim 4, wherein an extent of the deformation is limited, by forcible contact between at least one point on an exterior surface of the first flexible end section and an interior surface of the first through-hole.

7. The assembly of claim 1, wherein the capture member further secures a second cable at predetermined position relative to the substrate.

8. The assembly of claim 1, wherein the substrate comprises a printed circuit board with at least one signal trace.

9. The assembly of claim 1, further comprising a first daughter board mechanically coupled with the substrate and comprising a first signal path in electrical continuity with the first projecting pin.

10. The assembly of claim 9, further comprising a second daughter board mechanically coupled with the substrate and comprising a second signal path.

11. The assembly of claim 1, the first cable further comprising a second conductive member.

12. The assembly of claim 11, wherein the first and second conductive members comprise a differential pair.

13. The assembly of claim 12, wherein the first cable is a coaxial cable.

14. The assembly of claim 12, wherein the first cable comprises a twisted pair of conductors.

15. The assembly of claim 1, wherein the first cable comprises a conductive shield.

16. The assembly of claim 1, wherein the first conductive member is disposed within a first outer insulating sleeve.

17. The assembly of claim 11, wherein a portion of the first conductive member and the second conductive member are both disposed within a first outer insulating sleeve.

18. An electronic assembly comprising:

a substrate having first and second surfaces;

a through-hole extending through the substrate from a first opening at the first surface of the substrate to a second opening at the second surface of the substrate;

a first projecting pin extending into the first opening into the through-hole and terminating at a pin terminal secured within the through-hole;

a cable that includes a conductive member with first and second flexible end sections, the first flexible end section terminating at a first cable terminal, the first flexible end section extending into the second opening and including a spring structure that includes first and second bends within the through-hole, and the first cable terminal being forcibly engaged, by a first force, against the pin terminal secured within the through-hole; and

a capture member disposed adjacent to the second surface of the substrate,

wherein the capture member secures the cable at a predetermined position relative to the substrate,

wherein the capture member exerts a second force on the cable urging the cable toward the through-hole, at least some of the second force being transmitted from through the cable and into the pin terminal in the form of the first force, and

wherein the capture member is secured in a fixed position relative to the substrate.
