Method and apparatus for enclosing a cable splice

Claim 2

A flexible cable splice enclosure comprising a tubular housing of soft resilient flexible material having integrally formed tubular end portions at either end, the tubular housing freely bending in an arc along its longitudinal axis, each end portion having a resilient tapered interior wall, means providing a continuous rigid non-expandable band surrounding said tapered wall to limit outward expansion of the resilient flexible material forming said tapered wall, a tapered plug of resilient flexible material surrounding the cable inserted into each end portion of the tubular housing, and means forming a lip projecting radially inwardly of the tapered surface at the outer margins of the tapered walls for retaining the plugs in the end portions of the housing.

Claim 3

Apparatus of claim 1 wherein the means providing a rigid band is formed of a metal sleeve embedded in the tubular end portions.

Claim 4

Apparatus of claim 1 wherein the means providing a rigid band includes a collar formed of molded rigid plastic fitted snuggly around the outside of each tubular end portion.

Claim 5

The enclosure of claim 3 wherein each collar has a radially inwardly projecting lip around the outer margin, the lip extending inwardly of the inner surface of the tubular end portion, the lip forming an opening substantially the same size as the smaller end of the tapered plug, the larger end of the tapered plug engaging the inside of the lip of the collar to secure the plug in place within the offset end portion.

Claim 6

The enclosure of claim 3 wherein the rigid collar holds the plug and surrounding end portion of the housing in compression at the interface between the plug and surrounding end portion of the housing.

Claim 7

The enclosure of claim 3 wherein the rigid collar has a second lip at the inner margin thereof, the tubular housing extending through the opening formed by the second lip with the end portion having a shoulder engaging the inside of the second lip to secure the collar against axial movement relative to the housing.

Claim 8

The enclosure of claim 1 further including a coil spring coaxial with the tubular housing.

Claim 9

The enclosure of claim 8 wherein the coil spring is embedded in material forming the tubular housing.

Claim 10

Apparatus of claim 2 wherein the outer edge of the tubular end portions are formed with a radially inwardly projecting lip.

Claim 11

A flexible cable splice enclosure which bends with the cable, comprising: a tubular housing of resilient flexible material having an integrally formed radially offset tubular end portion at each end, the offset end portions having an inner diameter slightly larger than the inner diameter of the housing, the inner surface of the end portions being tapered to provide a larger diameter toward the outer edge of the end portions, means forming a non-expandable band around each of the end portions, tapered plugs fitting snuggly into the tapered inner surfaces of the end portions within the means forming a band, the band means holding the tapered plugs in a state of compression, each plug having at least one opening for receiving a cable, coil spring means imbedded in the housing between the end portions for holding the flexible material in a tubular shape while allowing the housing to bend freely, and means forming a lip projecting radially inwardly at the outer ends of the housing for engaging the plugs and retaining the plugs in the end portions.

Claim 12

A flexible cable splice enclosure which bends with the cable, comprising: a tubular housing of resilient flexible material having an integrally formed radially offset tubular end portion at each end, the offset end portions having an inner diameter slightly larger than the inner diameter of the housing, the inner surface of the end portions being tapered to provide a larger diameter toward the outer edge of the end portions, means forming a non-expandable band around each of the end portions, tapered plugs fitting snuggly into the tapered inner surfaces of the end portions within the means forming a band, the band means holding the tapered plugs in a state of compression, each plug having at least one opening for receiving a cable, coil spring means imbedded in the housing between the end portions for holding the flexible material in a tubular shape while allowing the housing to bend freely, and means forming a lip projecting radially inwardly at the outer ends of the housing for engaging the plugs and retaining the plugs in the end portions.
