Crimp tool is for and a method forms a strain relief connector including an optical fiber, a cover enclosing the optical fiber. The cover has an inner surface, an outer surface, a first end and a second end, the first end having a tapered portion that extends radially outwardly. A sleeve surrounds the cover and has a first inner volume and a first interior shoulder, a portion of the outer surface of the tapered portion abuts the first interior shoulder. The sleeve and the cover are simultaneously compressed forming a compressed portion. The cover and the sleeve are deformed such that the cover substantially fills the first inner volume of the sleeve.

A strain relief connector, including an optical fiber, a cover enclosing the optical fiber. The cover has an inner surface, an outer surface, a first end and a second end, the first end having a tapered portion that extends radially outwardly. A sleeve surrounds the cover and has a first inner volume and a first interior shoulder, a portion of the outer surface of the tapered portion abuts the first interior shoulder. The sleeve and the cover are simultaneously compressed forming a compressed portion. The cover and the sleeve are deformed such that the cover substantially fills the first inner volume of the sleeve.

Strain relief connector for fiber optic cable and method of making same

A strain relief connector for a fiber optic cable has an optical fiber enclosed within a cover having an outer diameter. A relatively long sleeve surrounds the cover and has an inner surface at an inner diameter, the inner diameter being substantially larger than the outer diameter of the cover. Portions of the sleeve and the fiber optic cable are compressed by a die, forming compressed portions having widths substantially larger than their heights and causing the inner surface of the sleeve to frictionally engage the outer surface of the cover layer and the inner surface of the cover to fictionally engage the outer surface of the optical fiber enclosed therein. The length of the sleeve and the configuration of the compressed portion allow a relatively high area of frictional resistance between the buffer layer and the sleeve.

An enclosure for an electrical device includes a first wall portion. The first wall portion has a first cable through passageway with an edge, a portion of the edge being rolled. A second wall portion is adjacent the first wall portion and has a removable knock-out portion at least partially covering a second cable through passageway.

Open ended, rolled edge through passageway for routing cable

A connector assembly for the at least partially stripped end of an optical fiber cable includes a crimp ring (10) having a longitudinal bore (14) therethrough, the bore having a large diameter portion (20) and a small diameter portion (22). The large diameter portion is adapted to engage a jacketed segment of cable (28) whereas the small diameter portion (22) is adapted to encompass an unjacketed segment of cable (28). The crimp ring (10) is crimped onto the unjacketed segment about small diameter portion (22), and coupling means, e.g., flange member (24), are used to couple crimp ring (10) to connector plug (36) by crimping on flange member (24). The connector plug (36) receives crimp ring (10) therein, has a bore (38) through which the cable (28) passes, and has an outlet (42) where the cable (28) is cleaved.

Optical fiber cable connector assembly

Photodynamic therapy apparatus providing improved light distribution with an end fitting for use with clad optical fibers, which apparatus cooperates with an unclad stripped terminal end of the optical fiber that is inwardly tapered towards its end such that light scattering media disposed between a glass tube surrounding at least the tapered portion of the optical fiber provides improved and predictable light distribution, the media being suitably cured to a rigid relationship thereby to continuously provide improved light distribution.
