Cable gland assembly

摘要

A cable gland assembly for attaching a shielded cable to an electronic enclosure includes a cable gland housing enclosing and in electrical contact with exposed cable shielding of the shielded cable and providing an electrically conductive pathway between the cable shielding and the electronic enclosure. The cable gland housing further encloses a shield pressure ring disposed to hold the exposed cable shielding in contact with the cable gland housing, a weather gasket, and an exposed portion of a cable strength member. The cable gland assembly includes environmental molding disposed within the cable gland housing to bond to and fix in place the exposed cable shielding, shield pressure ring, weather gasket, and exposed cable strength member. An outer molding is disposed around the cable gland housing.

1. A cable gland assembly for attaching a shielded cable to an enclosure housing wherein the shielded cable comprises at least one conductive strand surrounded by a cable shielding layer wherein the cable shielding layer is surrounded by a cable sheath comprising:
a cable gland housing formed by an annular wall surrounding a hollow cavity wherein the annular wall includes an inside surface facing the hollow cavity and an outside surface radially opposed to the inside surface, wherein a first end of the annular wall is configured to mechanically interface with the enclosure housing through a housing aperture and wherein a second end of the annular wall is configured to mechanically interface with a first terminal end of the shielded cable, wherein a first aperture defined by the inside surface at the first end provides access from the hollow cavity into the enclosure housing through the housing aperture and a second aperture defined by the inside surface at the second end provides access for receiving a first terminal end of the shielded cable into the hollow cavity; wherein a portion of the cable sheath is stripped from the first terminal to expose the cable shielding layer inside the hollow cavity and wherein a portion of the cable shielding layer is stripped from the first terminal end to leave a length of the cable shielding layer exposed and flayed radially outward inside the hollow cavity; a weather gasket comprising an annular ring disposed inside the hollow cavity between the cable sheath and the inside surface proximate to the second aperture, wherein the weather gasket is configured to apply a radially inwardly directed compression force against the cable sheath when the weather gasket is compressed between the inside surface and the cable sheath; a cable shield pressure ring comprising an annular ring installed inside the hollow cavity between the at least one conductive strand and the flayed out cable shielding layer wherein the cable shield pressure ring is configured to apply an expansion force directed radially outward from a central axis of the annular ring wherein the expansion force directed radially outward acts on the flayed out cable shielding layer forcing the flayed out cable shielding layer into mating contact with the inside surface.
