Abstract
Abstract A right angle strain relief system is provided for an optical fiber cable. A fiber optic connector terminates a fiber of the cable on a longitudinal connector axis. A right angle strain relief boot extends from a rear of the connector and has a cable-receiving passage therethrough. The boot has a first leg portion and a second leg portion joined by a bend. The first leg portion is on the longitudinal connector axis and defines a proximal end of the boot coupled to the rear of the connector. The second leg portion extends transversely of the longitudinal connector axis and defines an open distal end of the boot from which the optical fiber cable extends. The boot is rotatable relative to the connector about the longitudinal connector axis. A slot is provided in the boot extending from the open distal end thereof generally to at least the bend in the boot. The slot is of a width to allow the optical fiber cable to be moved outwardly of the second leg portion to a position projecting from the first leg portion generally on the longitudinal connector axis. The boot can be rotated to various angular orientations relative to the connector, while the cable is in the axial position, without twisting the cable.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
242 words
In a right angle strain relief system for an optical fiber cable, including a fiber optic connector for terminating a fiber of the cable on a longitudinal connector axis, and a right angle strain relief boot extending from a rear of the connector, the boot having a cable-receiving passage therethrough, the boot having a first leg portion and a second leg portion joined at a bend, the first leg portion being on said longitudinal connector axis and defining a proximal end of the boot coupled to said rear of the connector, and said second leg portion extending transversely of the longitudinal connector axis and defining an open distal end of the boot from which the optical fiber cable extends, wherein the improvement comprises slot means in the boot extending from the open distal end thereof generally to at least the bend in the boot, the slot means being of a width to allow the optical fiber cable to be moved outwardly of the second leg portion to a position projecting from the first leg portion generally on the longitudinal connector axis, and complementary interengaging coupling means between the proximal end of the boot and the connector to provide for rotation of the boot about the longitudinal connector axis, whereby the cable can be moved out of the second leg portion through the slot means and the boot can be rotated to various angular orientations relative to the connector without twisting the cable.
Claim 2
Dependent Claim
242 words
In a right angle strain relief system for an optical fiber cable, including a fiber optic connector for terminating a fiber of the cable on a longitudinal connector axis, and a right angle strain relief boot extending from a rear of the connector, the boot having a cable-receiving passage therethrough, the boot having a first leg portion and a second leg portion joined at a bend, the first leg portion being on said longitudinal connector axis and defining a proximal end of the boot coupled to said rear of the connector, and said second leg portion extending transversely of the longitudinal connector axis and defining an open distal end of the boot from which the optical fiber cable extends, wherein the improvement comprises slot means in the boot extending from the open distal end thereof generally to at least the bend in the boot, the slot means being of a width to allow the optical fiber cable to be moved outwardly of the second leg portion to a position projecting from the first leg portion generally on the longitudinal connector axis, and complementary interengaging coupling means between the proximal end of the boot and the connector to provide for rotation of the boot about the longitudinal connector axis, whereby the cable can be moved out of the second leg portion through the slot means and the boot can be rotated to various angular orientations relative to the connector without twisting the cable.
Claim 3
Dependent Claim
49 words
In a right angle strain relief system as set forth in claim 1, wherein said bend in the boot forms generally forwardly and rearwardly facing sides of the boot running into the second leg portion, and the slot means is located in the rearwardly facing side of the boot.
Claim 4
Dependent Claim
59 words
In a right angle strain relief system as set forth in claim 1, wherein said boot is fabricated of flexible material and said slot means includes a mouth near the distal end of the boot, the mouth being narrower than the cable to provide a snap-fitting restriction for the cable to pass into and out of the cable-receiving passage.
Claim 5
Dependent Claim
52 words
In a right angle strain relief system as set forth in claim 3, wherein said bend in the boot forms generally forwardly and rearwardly facing sides of the boot running into the second leg portion, and the slot means and the mouth are located in the rearwardly facing side of the boot.
Claim 6
Dependent Claim
30 words
In a right angle strain relief system as set forth in claim 3, wherein the width of said slot means is approximately the same as the diameter of the cable.
Claim 7
Dependent Claim
33 words
In a right angle strain relief system as set forth in claim 1, wherein said slot means extends from the open distal end of the boot substantially through the bend in the boot.
Claim 8
Dependent Claim
49 words
In a right angle strain relief system as set forth in claim 6, wherein said bend in the boot forms generally forwardly and rearwardly facing sides of the boot running into the second leg portion, and the slot means is located in the rearwardly facing side of the boot.
