Abstract

A transceiver for a two-connector system includes a circuit board, at least one cable attached to the circuit board, and a housing arranged to contain the circuit board. The two-connector system includes a front connector and a back connector. When the transceiver is connected to the two-connector system, a front edge of the circuit board is arranged to engage with the front connector and an intermediate portion of the circuit board is arranged to engage with the back connector.

First claim

What is claimed is:

1. A transceiver for a two-connector system including a front connector and a back connector connected to a substrate, the transceiver comprising:
a circuit board;
at least one cable attached to the circuit board; and
a housing arranged to contain the circuit board; wherein
when the transceiver is connected to the two-connector system, at least one front pad arranged along a front edge of the circuit board is arranged to engage with at least one corresponding contact of the front connector and at least one intermediate pad arranged along an intermediate portion of the circuit board is arranged to engage with at least one corresponding contact of the back connector; and
the transceiver is structured to simultaneously mate and unmate with the front connector and the back connector.

2. The transceiver of claim 1 , wherein the housing includes a clip arranged to engage with at least one slot of the back connector.

3. The transceiver of claim 2 , wherein the housing is arranged such that the clip is aligned to engage with the at least one slot of the back connector when the front edge of the circuit board is engaged with the front connector.

4. The transceiver of claim 1 , wherein:
the circuit board includes at least one notch; and
the housing includes a clip arranged to pass through the at least one notch of the circuit board.

5. The transceiver of claim 1 , wherein the at least one cable includes at least one of a coaxial cable, a shielded coaxial cable, a twinaxial cable, a twisted pair cable, a shielded twisted pair cable, and a shielded twinaxial cable.

6. The transceiver of claim 5 , wherein a conductor of the coaxial cable is electrically connected to a pad of the circuit board and a conductive shield of the coaxial cable is electrically connected to a ground plane of the circuit board.

7. The transceiver of claim 1 , wherein an epoxy covers the at least one cable and at least one pad of the circuit board.

8. The transceiver of claim 7 , wherein a dielectric constant of the epoxy is within about ±20% of a dielectric constant of the circuit board.

9. The transceiver of claim 7 , wherein the epoxy and the circuit board each have a dielectric constant between about 3.9 and about 4.2.

10. The transceiver of claim 1 , wherein the at least one cable includes a first cable and a second cable.

11. The transceiver of claim 10 , wherein electrical traces that are electrically connected to the first cable are arranged only on a top surface of the circuit board.

12. The transceiver of claim 10 , wherein electrical traces that are electrically connected to the second cable are arranged on a bottom surface of the circuit board.

13. The transceiver of claim 10 , wherein:
a first epoxy covers the first cable and a first pad of the circuit board; and
a second epoxy covers the second cable and a second pad of the circuit board.

14. The transceiver of claim 1 , wherein the at least one cable is electrically connected to at least one pad near the front edge of the circuit board that is connected to the at least one front pad.

15. The transceiver of claim 1 , wherein the housing includes undercuts arranged to receive at least one edge of the circuit board and alignment pins arranged to be inserted into holes in the circuit board.

16. The transceiver of claim 1 , wherein the front connector is a 0.5-mm pitch edge-card connector; and
the circuit board has a routing tolerance of +/−0.001″ for engaging with the front connector.

17. A two-connector system comprising:
a substrate;
a front connector and a back connector connected to the substrate; and
a transceiver connected to the substrate through the front connector and the back connector, the transceiver including:
a circuit board including at least one front pad arranged along a front edge of the circuit board and at least one intermediate pad arranged along an intermediate portion of the circuit board;
at least one cable attached to the circuit board; and
a housing arranged to receive the circuit board; wherein
the transceiver simultaneously mates and unmates with the front connector and the back connector; and
when the transceiver is mated with the front connector and the back connector, the at least one front pad engages with at least one corresponding contact of the front connector and the at least one intermediate pad engages with at least one corresponding contact of the back connector.
