Abstract
Abstract A feedthrough device is provided for sealing a supply line as it passes through an aperture in a wall member such, for example, as the housing of electrical apparatus. The device, which is generally tubular, comprises a first member which is radially inwardly deformable and can be pushed through the aperture and a second member which can telescopically engage the first member so as to co-operate with it to clamp against the wall member and provide a seal whilst at the same time preventing radial inward deformation of the first member. A recoverable sleeve member, which may be provided on, or be integral with, either of the first or second members engages the supply line to effect a seal therewith.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
183 words
A feedthrough device for sealing a supply line within an aperture in a wall member, which comprises (a) a first tubular member comprising a portion adapted to extend through the aperture, which portion is radially deformable to allow insertion of said portion through the aperture and is provided with a laterally extending shoulder surface adapted to abut one side of the wall to prevent withdrawal of said portion through the aperture, the first tubular member abutting only said one side of the wall; (b) a second tubular member having a relatively non-deformable portion adapted to engage with the first tubular member to restrain the laterally extending shoulder surface of the deformable portion against radially inward deformation; (c) an outwardly projecting flange member coaxially disposed in relation to the first tubular member and axially movable with respect thereto to co-operate with the laterally extending shoulder surface to exert an axial clamping action therebetween thereby effecting a seal at the wall member adjacent said flange member, and (d) a recoverable sleeve adapted, on recovery, to effect a seal between the device and the supply line.
Claim 2
Dependent Claim
183 words
A feedthrough device for sealing a supply line within an aperture in a wall member, which comprises (a) a first tubular member comprising a portion adapted to extend through the aperture, which portion is radially deformable to allow insertion of said portion through the aperture and is provided with a laterally extending shoulder surface adapted to abut one side of the wall to prevent withdrawal of said portion through the aperture, the first tubular member abutting only said one side of the wall; (b) a second tubular member having a relatively non-deformable portion adapted to engage with the first tubular member to restrain the laterally extending shoulder surface of the deformable portion against radially inward deformation; (c) an outwardly projecting flange member coaxially disposed in relation to the first tubular member and axially movable with respect thereto to co-operate with the laterally extending shoulder surface to exert an axial clamping action therebetween thereby effecting a seal at the wall member adjacent said flange member, and (d) a recoverable sleeve adapted, on recovery, to effect a seal between the device and the supply line.
