Method for terminating non-metallic transmission cables
First Claim
1. A method for terminating a transmission cable comprising strength members wrapped around a core structure containing transmission media, the method comprising the steps of:
- (a) providing an inner termination cone and an outer termination cone, wherein the inner termination cone has an internal channel and an external surface, and the outer termination cone has a bore configured to receive the inner termination cone;
(b) removing a firs length of the strength members from the core structure of the transmission cables to provide exposed strength members,(c) folding back at least a portion of the exposed strength members so that at least the portion of the exposed strength members is placed against the external surface of the inner termination cone, the inner termination cone having been placed over the core structure so that the strength members have a second length disposed in the internal channel between the core structure and the inner termination cone;
(d) applying an adhesive to the exposed strength members located on the external surface, and(e) securing the outer termination cone over the inner termination cone and exposed strength members and adhesive placed thereon.

Abstract
This invention relates to non-metallic, corrosion-resistant strength systems for underwater power and communications systems and methods for terminating such cables. The strength system comprises two non-metallic strength members; each strength member is comprised of at least one glass strand, and each strand is comprised of a plurality of glass filaments that are bound together with a polymeric material. The first strength member is applied in a helical lay over transmission media which forms the core of the cable, and the second strength member is applied over the lay of the first strength member in a helical lay having a circular direction opposite to the lay of the first strength member. The invention further embraces a method of terminating such cables involving the use of an inner termination cone, an adhesive used to secure the strength members onto the inner termination cone, and an outer termination cone which is secured over the inner termination cone and adjoining strength members.

11. A method for terminating a transmission cable comprising strength members wrapped around a core structure containing transmission media, the method comprising the steps of:
-
(a) providing an inner termination cone, an outer termination cone, wherein the inner termination cone has a first end and a second end, an internal channel opening to the first and second ends, and an external surface, and the outer termination cone has a bore configured to receive the inner termination cone; (b) placing the inner termination cone over the transmission cable so that the transmission cable runs through the internal channel from the first to the second ends; (c) removing a length of the strength members from the core structure adjacent to the first end of the inner termination cone to provide exposed strength members; (d) folding back at least a portion of the exposed strength members over the external surface of the inner termination cone toward the second end so the exposed strength members rest against the external surface of the inner termination cone from the first end toward the second end; (e) wrapping a length of yarn around the exposed strength members and external surface of the inner termination cone, the length of yarn being wrapped circularly about the inner termination cone between the first and second ends; (f) applying an adhesive to the exposed strength members and length of yarn on the external surface; and (g) securing the outer termination cone over the inner termination cone wherein the outer termination cone is placed over the exposed strength members, yarn and adhesive.

12. A method for terminating a transmission cable comprising strength members wrapped around a core structure containing transmission media, the method comprising the steps of:
-
(a) providing an inner termination cone, an outer termination cone, and a mating assembly, wherein the inner termination cone has a first end and a second end, an internal channel opening to the first and second ends, and an external surface;
the outer termination cone has two ends, a bore opening to the two ends and dimensioned to receive the inner termination cone therein, the bore having first threads adjacent one of the two ends; and
the mating assembly has second threads dimensioned to mate with the first threads on the bore;(b) placing the inner termination cone over the transmission cable so that the transmission cable runs through the internal channel from the first to the second ends; (c) removing a section of the length of the strength members from the core structure adjacent the first end of the inner termination cone to provide exposed strength members, (d) folding back at least a portion of the exposed strength members over the external surface of the inner termination cone toward the second end so that the strength members simultaneously have a first length sandwiched between the core structure and the inner termination cone and a second length resting against the exterior surface of the inner termination cone from the first to the second end; (e) wrapping a length of yarn around the exposed strength members and external surface of the inner termination cone, the length of yarn being wrapped circularly about the inner termination cone between the first and second ends; (f) applying an adhesive to the exposed strength members and length of yarn on the external surface; (g) securing the outer termination cone over the inner termination cone so that the threads of the bore are adjacent the first end of the inner termination cone; and (h) threading the mating assembly to the outer termination cone to close the bore.
