Strain relief boot for a fiber optic connector
First Claim
Patent Images
1. A fiber optic connector comprising:
- a connector housing having a distal end and a proximal end;
a ferrule assembly having a ferrule and a ferrule spring, the ferrule having a distal end face that is accessible at the distal end of the connector housing, the ferrule spring biasing the ferrule in a distal direction relative to the connector housing;
a boot mounted at the proximal end of the connector housing, the boot having a distal end that mounts over the proximal end of the connector housing and a proximal end, the boot defining a central axis that extends along a length of the boot from the distal end of the boot to the proximal end of the boot, the boot defining a central passage that extends through the length of the boot, the boot including a strain relief portion adjacent the proximal end of the boot, the strain relief portion of the boot having a truncated, conical outer shape, the strain relief portion of the boot being formed by a plurality of co-axial rings separated by axial gaps, the rings being interconnected by axial links that extend across the axial gaps, the central passage having a proximal portion corresponding to a length of the strain relief portion, the proximal portion of the central passage defining a transverse cross-dimension, and a majority of the rings of the strain relief portion of the boot having radial thicknesses that are at least 50 percent as long as the transverse cross-dimension.

Abstract
A connector including a housing having a distal end and a proximal end has a ferrule assembly having a ferrule and a ferrule spring. The ferrule spring biases the ferrule in a distal direction. A boot is mounted at the proximal end. The boot has a distal end mounting over the proximal end of the housing and a proximal end and defines a central axis. A central passage extends through a length of the boot. A strain relief portion is adjacent the proximal end of the boot and has a truncated, conical outer shape formed by co-axial rings separated by gaps, the rings being interconnected by links extending across the gaps. The central passage has a proximal portion corresponding to a length of the strain relief portion that defines a transverse cross-dimension A majority of the rings have radial thicknesses at least 50 percent as long as the transverse cross-dimension.
