Abstract
A termination system which improves the consistency and repeatability of the wicking of the liquid potting compound in the transition area between the potted and the imported filaments. The termination system controllably compresses the filaments within the transition area to produce repeatable wicking. The potting compound selected and the degree of compression employed combine to produce a desired wicking effect.
Claims20
A termination on a synthetic cable having filaments and an end, comprising:
- a. an anchor, having a first end, a second end, and an internal passage therebetween;
- b. wherein said internal passage includes an expanding cavity proximate said first end of said anchor;
- c. wherein a length of exposed filaments proximate said end of said cable is locked into solidified potting compound to form a solidified potted region within said expanding cavity;
- d. wherein said expanding cavity is defined by a revolved wall profile having a slope which is sufficient to prevent said solidified potted region from moving significantly toward said second end of said anchor when said cable is placed in tension;
- e. wherein said internal passage includes a wicking cavity located between said expanding cavity and said second end of said anchor;
- f. wherein said wicking cavity is defined by a revolved wall profile having a slope which is less than said slope within said expanding cavity, with said slope within said wicking cavity being configured so that when a portion of said cable is placed within said wicking cavity, said filaments of said cable lying within said wicking cavity are gradually compressed together when proceeding in the direction from said anchor's first end toward said anchor's second end, so that the voids between said filaments within said wicking cavity diminish when proceeding in the direction from said anchor's first end toward said anchor's second end;
- g. wherein the portion of said kicking cavity which is closest to said second end of said anchor is sized to compress said cable filaments lying in that portion of said wicking cavity tightly together, thereby inhibiting the wicking of said potting compound, while still in a liquid state, beyond that portion of said wicking cavity;
- and
- h. wherein the properties of said potting compound are selected so that said potting compound, while still in said liquid state, wicks through said voids in said wicking cavity in the direction from said anchor's first end toward said anchor's second end, thereby forming a wicking potting transition within said wicking cavity.

A termination on a synthetic cubic having filaments and an end, comprising:
- a. an anchor, having a first end, a second end, and on internal passage therebetween;
- b. wherein said internal passage includes an expanding cavity proximate said first end of said anchor;
- c. wherein a length of exposed filaments proximate said end of said cable is locked into solidified potting compound to form a solidified potted region within said expanding cavity;
- d. wherein said expanding cavity is defined by a revoked wall profile having a slope which is sufficient to prevent said solidified potted region from moving significantly toward said second end of said anchor when said cable is placed in tension;
- e. wherein said internal passage includes a straight portion located between said expanding cavity and said second end of said anchor;
- f. a compression sleeve surrounding said length of exposed filaments and lying within said straight portion, wherein said filaments of said cable lying within said compression sleeve are gradually compressed together when proceeding in the direction from said anchor's first end toward said anchor's second end, so that the voids between said filaments within said compression sleeve;
- and
- g. wherein the properties of said potting compound are selected so that said potting compound, while still in said liquid state, wicks through said voids in said length of filaments of said cable lying within said compression sleeve in the direction from said anchor's first end toward said anchor's second end, thereby forming a wicking putting transition within said compression sleeve.
