Abstract

An electrical connector includes a shell having a cavity and a wafer assembly received in the cavity. The wafer assembly includes a wafer housing holding a plurality of electrical wafers configured to be electrically mated to a mating connector. The wafer housing has a front end and the wafers extend forward from the front end being arranged parallel to each other within the cavity. Each wafer includes a first edge and a second edge with at least one trace between the first and second edges. An interfacial seal is provided along the front end. The interfacial seal is configured to seal between the electrical connector and the mating connector. The interfacial seal provides an environmental seal for the wafer assembly.

First claim

What is claimed is:

1. An electrical connector comprising:
a shell having a cavity;
a wafer assembly received in the cavity, the wafer assembly comprising a wafer housing holding a plurality of electrical wafers configured to be electrically mated to a mating connector, the wafer housing having a front end, the wafers extending forward from the front end and being arranged parallel to each other within the cavity, each wafer including a first edge and a second edge, each wafer including at least one trace between the first and second edges; and
an interfacial seal along the front end, the interfacial seal being configured to seal against the mating connector when mated to the front end, the interfacial seal providing an environmental seal for the wafer assembly.

2. The electrical connector of claim 1 , wherein the interfacial seal is sealed against each of the wafers of the wafer assembly.

3. The electrical connector of claim 1 , wherein the interfacial seal is sealed against upper and lower surfaces of each of the wafers of the wafer assembly.

4. The electrical connector of claim 1 , wherein the interfacial seal comprises a plurality of slots, the wafers pass through corresponding slots.

5. The electrical connector of claim 1 , wherein the interfacial seal includes a plurality of protrusions, the protrusions extend along corresponding wafers, distal ends of the protrusions being configured to seal against the mating connector.

6. The electrical connector of claim 1 , wherein the interfacial seal has a front and a rear, the rear sealing against the front end of the wafer assembly, the front being configured to seal against the mating connector.

7. The electrical connector of claim 1 , wherein the interfacial seal is mounted to the front end over the wafers.

8. The electrical connector of claim 1 , further comprising a flex harness comprising a plurality of flexible printed circuit boards (FPCBs), the FPCBs being electrically connected to corresponding wafers, wherein the FPCBs are directly terminated to the corresponding wafers.

9. The electrical connector of claim 8 , wherein the FPCBs are soldered to the corresponding wafers.

10. The electrical connector of claim 8 , wherein the FPCBs include flex seals sealed against the wafer housing and the corresponding FPCBs.

11. The electrical connector of claim 8 , wherein the FPCBs each include a grommet provided at an end of the FPCB, the grommet being secured to the corresponding wafer to provide an environmental seal for the FPCB.

12. An electrical connector comprising:
a shell having a cavity;
a wafer assembly received in the cavity, the wafer assembly comprising a wafer housing holding a plurality of electrical wafers configured to be electrically mated to a mating connector, the wafer housing having a front end, the wafers extending forward from the front end and being arranged parallel to each other within the cavity, each wafer including a first edge and a second edge, each wafer including at least one trace between the first and second edges; and
an interfacial seal along the front end, the interfacial seal being sealed against each of the wafers of the wafer assembly, the interfacial seal being configured to seal to the mating connector.

13. The electrical connector of claim 12 , wherein the interfacial seal is sealed against upper and lower surfaces of each of the wafers of the wafer assembly.

14. The electrical connector of claim 12 , wherein the interfacial seal comprises a plurality of slots, the wafers pass through corresponding slots.

15. The electrical connector of claim 12 , further comprising a flex harness comprising a plurality of flexible printed circuit boards (FPCBs), the FPCBs being electrically connected to corresponding wafers, wherein the FPCBs are directly terminated to the corresponding wafers.

16. The electrical connector of claim 15 , wherein the FPCBs include flex seals sealed against the wafer housing and the corresponding FPCBs.

17. An electrical connector comprising:
a shell having a cavity;
a wafer assembly received in the cavity, the wafer assembly comprising a wafer housing holding a plurality of electrical wafers configured to be electrically mated to a mating connector, the wafer housing having a front end, the wafers extending forward from the front end and being arranged parallel to each other within the cavity, each wafer including a first edge and a second edge, each wafer including at least one trace between the first and second edges; and
a flex harness comprising a plurality of flexible printed circuit boards (FPCBs), the FPCBs being electrically connected to corresponding wafers and extending rearward from the cavity, the flex harness having a flex seal configured to be sealed to at least one FPCB.

18. The electrical connector of claim 17 , further comprising an interfacial seal along the front end, the interfacial seal being configured to seal between the electrical connector and the mating connector, the interfacial seal providing an environmental seal for the wafer assembly.

19. The electrical connector of claim 17 , wherein the flex seal seals the at least one FPCB to the corresponding wafer.

20. The electrical connector of claim 17 , wherein the flex seal seals the at least one FPCB to at least one of the shell and the wafer housing.

21. The electrical connector of claim 17 , wherein the flex seal includes a plurality of grommets provided at an end of the corresponding FPCB, the grommets being secured to the corresponding wafer to provide strain relief and sealing against the FPCB.
