Abstract

A connector module includes a housing and a gasket. The housing is defined by a first shell and a second shell that mate at a seam. The housing includes a cable exit region extending along a cable axis. A passage through the cable exit region has an elliptical cross-section along a plane perpendicular to the cable axis. The gasket is within the passage of the cable exit region. An outer perimeter of the gasket in an uncompressed state has a non-elliptical cross section along a plane perpendicular to the cable axis. The gasket has an outer side engaging the inner surface of the cable exit region and an inner side configured to engage at least one cable received within the cable exit region. As the shells are mated, the gasket is sandwiched in a compressed state between the at least one cable and the cable exit region.

First claim

What is claimed is:

1. A connector module comprising: a housing defined by a first shell and a second shed that mate at a seam, and form an interior chamber therebetween, the housing including a cable exit region extending along a cable axis between the interior chamber and a cable opening of the housing, the cable exit region including a curved inner surface that defines a passage from the cable opening to the interior chamber, the passage having an elliptical cross-section along a plane perpendicular to the cable axis; and
and a gasket within the passage of the cable exit region, the gasket including a conductive material such that the gasket is electrically conductive, the gasket extending along the cable axis between a front and a rear, an outer perimeter of the gasket in an uncompressed state having a non-elliptical cross-section along the plane perpendicular to the cable axis, the gasket having an outer side engaging the curved inner surface of the cable exit region and an inner side configured to engage at least one cable received within the cable exit region;
wherein the gasket has a compressive layer that is surrounded by a conductive layer, the conductive layer being composed of the conductive material of the gasket, the conductive layer having a tubular shape and extending between first and second ends, the conductive layer defining the inner side and the outer side of the gasket;
wherein, as the first and second shells are mated, the gasket is sandwiched in a compressed state between the at least one cable and the cable exit region, the outer side of the gasket in the compressed state configured to at least partially conform to the curved inner surface of the cable exit region to at least partially seal the passage between the at least one cable and the cable exit region.

2. The connector module of claim 1 , wherein the gasket has a rectangular cross-section in the uncompressed state along the plane perpendicular to the cable axis.

3. The connector module of claim 1 , wherein the gasket includes a crease on the inner side of the gasket in a creased state of the gasket, the crease extending along the cable axis between the front and rear of the gasket, the at least one cable being received over the crease, the gasket bending at the crease as the first and second shells are mated.

4. The connector module of claim 3 , wherein the outer side of the gasket includes a slit opposite the crease, the slit extending radially partially through the gasket.

5. The connector module of claim 1 , wherein the gasket in the uncompressed state extends along a gasket axis between the first and second ends, the gasket axis being transverse to the cable axis.

6. The connector module of claim 1 , the compressive layer is a non-conductive foam and the conductive layer is composed of a conductive fabric.

7. The connector module of claim 1 , wherein the gasket defines a channel extending through the gasket From the front to the rear along the cable axis, the channel configured to receive the at least one cable therein.

8. The connector module of claim 7 , wherein the gasket includes at least one side groove that extends between the front and rear, the side groove aligned proximate to the seam of the housing, each side groove having an uncompressed height defined by an upper ledge and a lower ledge, wherein, as the First and second shells are mated, the upper and lower ledges are moved relatively towards each other such that the side groove has a compressed height that is less than the uncompressed height.

9. The connector module of claim 1 , wherein the inner and outer sides of the gasket extend laterally between first and second ends of the gasket, the outer side of the gasket in the uncompressed state engaging the curved inner surface of the cable exit region at edges of the gasket proximate to the first and second ends such that a space is defined between the outer side of the gasket and the curved inner surface of the cable exit region laterally between the edges of the gasket, wherein, in the compressed state, the outer side or the gasket conforms to the curved inner surface such that a volume of the space between the outer side and the curved inner surface is reduced relative to the volume of the space in the uncompressed state.

10. A connector module comprising: a housing defined by a lower shell and an upper shell that mate at a seam, an interior chamber within the housing is formed between the lower and upper shells, each of the lower and upper shells including a cable exit segment, each cable exit segment having walls that engage the walls of the other cable exit segment at the seam to define a cable exit region that extends along a cable axis, inner surfaces of the cable exit segments together defining a passage through the cable exit region from the interior chamber to a cable opening, the inner surfaces being curved such that the passage has an elliptical cross-section along a plane perpendicular to the cable axis;
and a gasket disposed in the cable exit segment of the lower shell, the gasket including a conductive sleeve that, in an uncompressed state, extends along a gasket axis between a first end and a second end, the gasket axis being transverse to the cable axis, the conductive sleeve surrounding a compressive layer, the conductive sleeve along an outer side of the gasket engaging the inner surface of the cable exit segment of the lower shell, the conductive sleeve along an inner side of the gasket configured to engage at least one cable received between the cable exit segments of the upper and lower shells, the inner side of the gasket defining a crease in a creased state, the crease extending along the cable axis, the at least one cable being received over the crease, the gasket bending at the crease at least partially around the at least one cable as the lower and upper shells are mated.

11. The connector module of claim 10 , wherein the walls of the cable exit segment of the lower shell are left and right walls, the first and second ends of the gasket being disposed proximate to the corresponding left and right walls of the lower shell, wherein, as the lower and upper shells are mated, the gasket bends at the crease and the first and second ends are forced radially inward towards the at least one cable and away from the first and second walls.

12. The connector module of claim 10 , wherein the first and second ends of the gasket are received within the cable exit segment of the upper shell as the lower and upper shells are mated, the first and second ends engaging each other such that the gasket surrounds an outer perimeter of the at least one cable within the cable exit region.

13. The connector module of claim 10 , wherein the crease is one of plural creases on the inner side of the gasket; the gasket further including plural slits on the outer side of the gasket, each slit opposite a corresponding crease, each slit extending partially through the gasket, wherein the gasket includes multiple gasket segments defined between the slits, the gasket in a compressed state configured to bend at the creases to at least partially conform to the curved inner surfaces of the lower and upper shells and to surround at least most of an outer perimeter of the at least one cable, the gasket segments engaging the at least one cable at different locations along the outer perimeter.

14. A connector module comprising: a housing defined by a first shell and a second shell that mate at a seam, an interior chamber within the housing being formed between the first and second shells, each of the first and second shells including a cable exit segment, each of the cable exit
