Abstract
Abstract A capping accessory for hermetically sealing a cable end temporarily or permanently. The accessory is typically molded in one piece from a thermoplastic material sealable to potting compound and preferably includes a locator boss within its inner end as well as a plurality of flexible tangs projecting axially from its open end with their free ends securable to the adjacent surface of a cable assembled into the accessory. Adhesive tape wrapped about the cable in an area intermediate the top and bottom of the accessory aids in centering the cable therewithin as well as acts as an anchor ring to hold the cable against withdrawal from potting compound filling the accessory and surrounding the anchor ring.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
176 words
In combination with the end of a cable, a cable capping accessory comprising a deep cup-shaped main body of thermoplastic material having an ID substantially greater than the OD of the end portion of said cable, the lip edges of said main body being notched axially thereof to provide a pair of long tough flexible resilient tangs projecting axially from the diametrically opposed peripheral edge portions of the open end of said main body, means holding the outer free ends of said tangs secured against the juxtaposed exterior surfaces of said cable sheath after the end of the latter has been telescoped into said main body and cooperating to hold the cable end generally centered between the sidewalls of said main body, the edges of said tangs being spaced apart sufficiently to facilitate charging the interior of said main body with potting compound, and a charge of potting compound substantially filling the space between said cable and said main body and hermetically sealed to the interior surface thereof and to the adjacent surface of the cable.
Claim 2
Dependent Claim
176 words
In combination with the end of a cable, a cable capping accessory comprising a deep cup-shaped main body of thermoplastic material having an ID substantially greater than the OD of the end portion of said cable, the lip edges of said main body being notched axially thereof to provide a pair of long tough flexible resilient tangs projecting axially from the diametrically opposed peripheral edge portions of the open end of said main body, means holding the outer free ends of said tangs secured against the juxtaposed exterior surfaces of said cable sheath after the end of the latter has been telescoped into said main body and cooperating to hold the cable end generally centered between the sidewalls of said main body, the edges of said tangs being spaced apart sufficiently to facilitate charging the interior of said main body with potting compound, and a charge of potting compound substantially filling the space between said cable and said main body and hermetically sealed to the interior surface thereof and to the adjacent surface of the cable.
Claim 3
Dependent Claim
56 words
The combination defined in claim 1 characterized in the provision of spacer means between the inner end of said main body and the end of said cable for supporting the cable end axially from the inner end of the main body thereby assuring a substantial thicknesS of potting compound opposite the inner end of said cable.
Claim 4
Dependent Claim
26 words
The combination defined in claim 2 characterized in that said cup-shaped capping accessory and attached tangs are formed in one seamless piece from transparent thermoplastic material.
Claim 5
Dependent Claim
61 words
The combination defined in claim 1 characterized in the provision of a spacer 28 ring secured about the exterior of the cable and embedded in said potting compound, said spacer ring facilitating centering the cable in said main body while the potting compound is taking a set and being effective to anchor the cable to said compound and against withdrawal therefrom.
Claim 6
Dependent Claim
148 words
A one-piece molded thermoplastic capping accessory hermetically sealable to a cable end after telescopic assembly thereover, said capping accessory having a long tubular main body closed at one end and having a plurality of long resilient tangs projecting axially from diametrically opposed rim edge portions of the open end thereof, the free outer ends of said tangs being deflectable toward one another and adapted to be lashed against the sides of a cable end after the latter has been inserted into the open end of said capping accessory and their resiliency being effective to hold the cable end centered in the capping accessory while a charge of potting compound takes a set, and said accessory being chargeable with fluent potting compound of a type which takes a set and forms a strong hermetic seal with a cable sheath and with the juxtaposed interior surfaces of said capping accessory.
Claim 7
Dependent Claim
148 words
A one-piece molded thermoplastic capping accessory hermetically sealable to a cable end after telescopic assembly thereover, said capping accessory having a long tubular main body closed at one end and having a plurality of long resilient tangs projecting axially from diametrically opposed rim edge portions of the open end thereof, the free outer ends of said tangs being deflectable toward one another and adapted to be lashed against the sides of a cable end after the latter has been inserted into the open end of said capping accessory and their resiliency being effective to hold the cable end centered in the capping accessory while a charge of potting compound takes a set, and said accessory being chargeable with fluent potting compound of a type which takes a set and forms a strong hermetic seal with a cable sheath and with the juxtaposed interior surfaces of said capping accessory.
Claim 8
Dependent Claim
69 words
A cable end capping accessory as defined in claim 5 characterized in that the interior end of said main body includes a boss projecting therefrom and positioned to engage and act as a stop for the cable end as the latter is telescoped into assembled position over a cable end and leaving room between the cable end and the interior end of said main body to receive potting compound.
Claim 9
Dependent Claim
137 words
That method of hermetically sealing the end of a multiconductor cable which comprises, inserting the cable end into a tubular cup-shaped casing molded in one piece from tough resilient thermoplastic material and having its inlet end deeply notched to provide a pair of long resilient tangs diametrically opposed to one another along the opposite sides of the cable, pressing the outer free ends of said resilient tangs toward one another and lashing said free ends to the juxtaposed surfaces of the cable so that the stresses so created in said tangs act to hold the cable end centered within said cup-shaped casing while a charge of fluent potting compound is taking a set, and thereafter charging fluent potting compound into said casing between and near the junction of said tangs with the inlet end of said casing.
Claim 10
Dependent Claim
137 words
That method of hermetically sealing the end of a multiconductor cable which comprises, inserting the cable end into a tubular cup-shaped casing molded in one piece from tough resilient thermoplastic material and having its inlet end deeply notched to provide a pair of long resilient tangs diametrically opposed to one another along the opposite sides of the cable, pressing the outer free ends of said resilient tangs toward one another and lashing said free ends to the juxtaposed surfaces of the cable so that the stresses so created in said tangs act to hold the cable end centered within said cup-shaped casing while a charge of fluent potting compound is taking a set, and thereafter charging fluent potting compound into said casing between and near the junction of said tangs with the inlet end of said casing.
Claim 11
Dependent Claim
65 words
That method defined in claim 7 characterized in the steps of wrapping the cable inwardly of the end to be sealed with concentric convolutions of adhesive tape to form an anchor ringlet and having an outer diameter less than the interior diameter of said casing before assembling the casing thereover, and charging said potting compound into said casing to a depth submerging said anchor ringlet.
