Abstract
Abstract A sealing element is provided for use on insulated flat cables of the type having opposed rounded minor surfaces and opposed substantially flat parallel major surfaces which comprises an elongated body of resilient material having an orifice extending longitudinally within said body. The orifice has a width greater than its height. Opposed involute walls extend within said orifice substantially along the width of the orifice whereby the involute walls stretch and conform to the opposed substantially flat parallel major surfaces of the flat cable when placed thereon, thus providing a secure, watertight interference fit. Depending upon usage, the orifice may extend through the body or terminate within the body. Additionally, it is preferred that sealing rings be formed in the inner wall of the orifice.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A sealing element adapted to be used with an insulated flat cable having opposed substantially flat parallel major surfaces and opposed rounded minor surfaces comprising an elongated body of resilient material; an orifice having opposed side walls and opposed end walls extending within said body, said opposed side walls having a width greater than the height of said end walls; and said opposed side walls of said orifice having involute surfaces extending substantially across their width and within said orifice, said involute surfaces extending the length of said orifice and adapted to stretch and conform to substantially the entire major surfaces of a flat cable having opposed substantially flat parallel major surfaces and opposed rounded minor surfaces, said end walls of said orifice adapted to stretch and conform to the opposed rounded minor surfaces thereof so as to provide a watertight interference fit entirely about said cable.
Claim 2
Dependent Claim
147 words
A sealing element adapted to be used with an insulated flat cable having opposed substantially flat parallel major surfaces and opposed rounded minor surfaces comprising an elongated body of resilient material; an orifice having opposed side walls and opposed end walls extending within said body, said opposed side walls having a width greater than the height of said end walls; and said opposed side walls of said orifice having involute surfaces extending substantially across their width and within said orifice, said involute surfaces extending the length of said orifice and adapted to stretch and conform to substantially the entire major surfaces of a flat cable having opposed substantially flat parallel major surfaces and opposed rounded minor surfaces, said end walls of said orifice adapted to stretch and conform to the opposed rounded minor surfaces thereof so as to provide a watertight interference fit entirely about said cable.
Claim 3
Dependent Claim
37 words

The sealing element of claim 1 further comprising a peripheral should about the periphery of said elongated body.
Claim 9
Dependent Claim
39 words
The sealing element of claim 1 further comprising a cavity extending longitudinally within said elongated body from one end thereof; and wherein said orifice extends within said elongated body from the other end thereof and terminates at said cavity.
Claim 10
Dependent Claim
18 words
The sealing element of claim 1 further comprising sealing rings formed in the inner surface of said orifice.
