Advanced stranded cable termination methods and designs
Advanced components that are useful in providing a compact overall cable termination for a multi-stranded cable and in providing for the control and inspection of the individual components of a multi-stranded cable. Multiple individual cable strands are provided with a termination on their free end. These terminations are connected to a collector. An advanced collar is provided that assists in the transition of the strands as they leave the collector and transition to the structure found in the free portion of the cable.
1. An overall cable termination for a synthetic cable having multiple strands and a free cable portion, each strand including a strand termination attached thereto, said cable having a central axis, comprising:
a. an upper collector, having multiple receivers, each of said receivers being connected to one of a first group of said strand terminations, with said first group of said strand terminations being attached to a first group of said strands;
b. said strands diverging from said free cable portion to said collector;
c. a strand collar encircling said strands proximate said collector;
d. said strand collar being connected to said collector;
e. said strand collar being configured to constrain a lateral motion of at least some of said strands;
f. a lower collector offset from said upper collector in a direction that is parallel to said central axis of said cable;
g. said lower collector having multiple receivers, each of said receivers being connected to one of a second group of said strand terminations, with said second group of strand terminations being attached to a second group of said strands;
h. said lower collector being connected to said upper collector;
i. said upper collector having an outer perimeter;
j. said outer perimeter of said upper collector opening into a first plurality of slots wherein each of said first plurality of slots provides a passage between said outer perimeter of said upper collector and one of said multiple receivers in said upper collector;
k. said lower collector having an outer perimeter;
l. said outer perimeter of said lower collector opening into a second plurality of slots wherein each of said second plurality of slots provides a passage between said outer perimeter of said lower collector and one of said multiple receivers in said lower collector;
m. a passage through said upper collector and said lower collector; and
n. wherein said first group of said strands passes through said passage within said lower collector, with said first group of strands lying closer to said central axis of said cable than said second group of strands.
2. The overall cable termination for a synthetic cable as recited in claim 1 , wherein said strand collar includes at least one inspection port configured to allow visual inspection of at least one of said strand terminations while said at least one strand termination is connected to said collector.
3. The overall cable termination for a synthetic cable as recited in claim 1 , wherein
said receivers for said first group of said strand terminations are staggered with respect to said receivers for said second group of strand termination in order to reduce a volume of said overall cable termination.
4. The overall cable termination for a synthetic cable as recited in claim 1 , wherein:
a. said first group of strand terminations are connected to said receivers of said upper collector at a first level; and
b. said second group of strand terminations are connected to said receivers of said lower collector at a second level that is displaced from said first level.
5. The overall cable termination for a synthetic cable as recited in claim 1 , wherein said connection between each of said strand terminations and said collector is a rotation-limiting connection.
6. The overall cable termination for a synthetic cable as recited in claim 1 , further comprising a load indicator for at least one connection between one of said strands and said collector.
7. An overall cable termination for a synthetic cable having multiple strands and a free cable portion, each strand including a strand termination attached thereto, said cable having a central axis, comprising:
a. an upper collector, having multiple receivers, each of said receivers being connected to one of a first group of said strand terminations, with said first group of said strand terminations being attached to a first group of said strands;
b. said strands diverging from said free cable portion to said collector;
c. a strand collar encircling said strands proximate said collector;
d. said strand collar being connected to said collector;
e. said strand collar being configured to reroute at least some of said strands as said rerouted strands travel from said strand terminations to said free cable;
f. a lower collector offset from said upper collector in a direction that is parallel to said central axis of said cable;
g. said lower collector having multiple receivers, each of said receivers being connected to one of a second group of said strand terminations, with said second group of strand terminations being attached to a second group of said strands;
h. said lower collector being connected to said upper collector;
i. said upper collector having an outer perimeter;
j. said outer perimeter of said upper collector opening into a first plurality of slots wherein each of said first plurality of slots provides a passage between said outer perimeter of said upper collector and one of said multiple receivers in said upper collector;
k. said lower collector having an outer perimeter;
l. said outer perimeter of said lower collector opening into a second plurality of slots wherein each of said second plurality of slots provides a passage between said outer perimeter of said lower collector and one of said multiple receivers in said lower collector;
m. a passage through said upper collector and said lower collector; and
n. wherein said first group of said strands passes through said passage within said lower collector, with said first group of strands lying closer to said central axis of said cable than said second group of strands.
8. The overall cable termination for a synthetic cable as recited in claim 7 , wherein said strand collar includes at least one inspection port configured to allow visual inspection of at least one of said strand terminations while said at least one strand termination is connected to said collector.
9. The overall cable termination for a synthetic cable as recited in claim 7 , wherein
said receivers for said first group of said strand terminations are staggered with respect to said receivers for said second group of said strand terminations in order to reduce a volume of said overall cable termination.
10. The overall cable termination for a synthetic cable as recited in claim 7 , wherein:
a. said first group of strand terminations are connected to said receivers of said upper collector at a first level; and
b. said second group of strand terminations are connected to said receivers of said lower collector at a second level that is displaced from said first level.
