1. A cable bend limiter, comprising:
one or more joints each comprising an inner ball, an outer ball, one or two cylindrical sleeves and first and second washers; wherein the inner ball comprises two opposed truncated hemispheric sections with each truncated hemispheric section being coaxial to a respective first cable opening, each truncated hemispheric section having an attached cylindrical inner ball collar coaxial to and defining a respective first cable opening and extending from each respective truncated hemispheric section in an outward polar direction; wherein the outer ball comprises two interlocking outer ball sections, each outer ball section being coaxial to and defining a respective second cable opening, wherein the outer ball is sized for enclosing two opposed inner ball sections and allowing extension of a separate inner ball collar through the second cable opening of each interlocking outer ball section; wherein each sleeve of the one or two sleeves has a central axial opening axially attachable to a separate inner ball collar and coaxial with the first cable openings thereof, and each sleeve has one or two concave surfaces coaxial with the central opening and first cable opening of an attached inner ball collar, each concave surface being sized for engaging an outer surface of an outer ball section when a contained inner ball section is attached to the sleeve; wherein a first washer is located between an inner ball section and a respective outer ball section; wherein a second washer is located between an outer ball section and a respective concave surface of a sleeve; and wherein the respective first cable openings of two opposed inner ball sections contained within an outer ball can vary between axial alignment and a predetermined deviation from axial alignment in all radial directions. |
