Repair sleeve
A repair sleeve has first and second end portions, each of which has a substantially cylindrical outer surface. The end portions are bored to receive a cable of a particular diameter. The inner surface of each end portion may be stepped or tapered. The center portion of the repair sleeve, between the two end portions, has an interior diameter substantially larger than the nominal diameter of the cable so that the repair sleeve can be use on a frayed cable or a cable with a failing splice. The repair sleeve is split longitudinally into two interlocking portions, which, when separated, allows the damaged cable or failing splice under repair to be inserted into a first one of the portions in a radial direction. The other portion is then inserted into the first portion and the repair sleeve is swaged onto the cable.
1. A cable repair sleeve comprising: first and second end portions, each having a plurality of axially contiguous swaging segments and a substantially cylindrical outer surface across all of the swaging segments, each of the first and second end portions having an inner surface with each of the swaging segments having a successively decreasing inner diameter; a center portion having an interior diameter substantially larger than a largest inner diameter of either of the first and second end portions; wherein the repair sleeve is split longitudinally into two first and second interlocking portions, which, when separated, allow insertion, in a radial direction, of a cable into the first interlocking portion, and wherein the first and second interlocking portions have corresponding keying surfaces such that the second interlocking portion is axially insertable into the first interlocking portion and such that, when the second interlocking portion is axially inserted into the first interlocking portion, radial separation of the first and second interlocking portions is prevented.
2. The cable repair sleeve of claim 1 wherein the inner surface of each of the first and second end portions is stepped.
3. The cable repair sleeve of claim 1 wherein the inner surface of each of the first and second end portions is tapered.
4. A method of attaching the cable repair sleeve of claim 1 to a cable comprising: placing the first interlocking portion on the cable; placing the second interlocking portion into mating engagement with the first interlocking portion; compressing the swaging segments of the first and second end portions radially inwardly with a swaging tool.
5. The method of claim 4 wherein the first interlocking portion is placed on a cable with the center portion disposed around a frayed portion of the cable.
6. The method of claim 4 wherein the first interlocking portion is placed on a cable with the center portion disposed around a splice in the cable.
