Abstract
Abstract Apparatus for weatherproofing an electrical cable connecting device, particularly where both an improved cable seal and greater cable flexibility are attained. A cable sealing gland is disposed on a flexible diaphragm to relieve the strain developed in the gland when the cable flexes. Gland resistance to cable flexure is overcome by relieving axial strain through distortion of the diaphragm about an axis perpendicular to the axis of the cable. Separation of the gland from the cable is overcome by relieving lateral strain through distortion of the diaphragm to reorient the axis of the gland in the direction of cable flexure. The diaphragm is disposed on a spacing ring as the end wall of a sealing boot which is otherwise configured to fit conventionally over the cable connecting device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
In a weatherproof boot for an electrical cable connecting device including a sealing gland and a flat end wall disposed across one end of a cylindrical sleeve, said gland being disposed on said end wall to contiguously pass the cable along an arcuate axis of varying radius, the improvement comprising: said end wall having a portion bearing against the cable connecting device and a portion suspeNded above the cable connecting device as a freely flexing diaphragm, said sealing gland being centrally located on said suspended portion, said bearing portion translating stresses from said suspended portion to the cable connecting device and said suspended portion distorting to relieve strain in said sealing gland when the cable is flexed.
Claim 2
Dependent Claim
117 words
In a weatherproof boot for an electrical cable connecting device including a sealing gland and a flat end wall disposed across one end of a cylindrical sleeve, said gland being disposed on said end wall to contiguously pass the cable along an arcuate axis of varying radius, the improvement comprising: said end wall having a portion bearing against the cable connecting device and a portion suspeNded above the cable connecting device as a freely flexing diaphragm, said sealing gland being centrally located on said suspended portion, said bearing portion translating stresses from said suspended portion to the cable connecting device and said suspended portion distorting to relieve strain in said sealing gland when the cable is flexed.
Claim 3
Dependent Claim
24 words
The weatherproof boot of claim 1 wherein said bearing portion is a spacing ring, said spacing ring being peripherally disposed in said cylindrical sleeve.
Claim 4
Dependent Claim
44 words
The weatherproof boot of claim 1 wherein said sealing gland is annularly configured and is disposed within said suspended portion, lateral strain in said sealing gland perpendicular to the cable axis being relieved by distortion of said suspended portion when the cable is flexed.
Claim 5
Dependent Claim
48 words
The weatherproof boot of claim 1 wherein said sealing gland is cylindrically configured and extends from said suspended portion parallel to the cable axis, axial strain in said sealing gland parallel to the cable axis being relieved by distortion of said suspended portion when the cable is flexed.
Claim 6
Dependent Claim
61 words
The weatherproof boot of claim 1 wherein said sealing gland is cylindrically configured and extends through said suspended portion parallel to the cable axis, axial strain in said sealing gland parallel to the cable axis and lateral strain in said sealing gland perpendicular to the cable axis both being relieved by distortion of said suspended portion when the cable is flexed.
Claim 7
Dependent Claim
75 words
The weatherproof boot of claim 1 wherein said sleeve is configured to contiguously fit around the cable connecting device and includes means for sealing with a second weatherproof boot upon joining the cable connecting device to a mating device, said sealing means being disposed on said sleeve at the opposite longitudinal end from said end wall; and wherein said bearing portion is a spacing ring, said spacing ring being peripherally disposed in said cylindrical sleeve.
