Abstract
Abstract A sealing element is provided for use on insulated flat cables 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
163 words
A cable and sealing element comprising a flat cable having opposed rounded minor surfaces and opposed substantially flat parallel major surfaces; an elongated body of resilient material, said elongated body having a periphery greater than the periphery of said flat cable; an orifice extending longitudinally within said body having a width greater than its height and a periphery smaller than the periphery of said flat cable; opposed involute walls within said orifice extending substantially along said width of said orifice and extending the length of said orifice, and opposed arcuate end walls within said orifice interconnecting said opposed involute walls; said flat cable being inserted in said orifice with said opposed involute walls within said orifice stretching and conforming to the substantially flat parallel major surfaces of said cable and with said opposed arcuate end walls within said orifice stretching and conforming to the opposed rounded minor surfaces of said cable so as to provide a watertight interference fit entirely about said cable.
Claim 2
Dependent Claim
163 words
A cable and sealing element comprising a flat cable having opposed rounded minor surfaces and opposed substantially flat parallel major surfaces; an elongated body of resilient material, said elongated body having a periphery greater than the periphery of said flat cable; an orifice extending longitudinally within said body having a width greater than its height and a periphery smaller than the periphery of said flat cable; opposed involute walls within said orifice extending substantially along said width of said orifice and extending the length of said orifice, and opposed arcuate end walls within said orifice interconnecting said opposed involute walls; said flat cable being inserted in said orifice with said opposed involute walls within said orifice stretching and conforming to the substantially flat parallel major surfaces of said cable and with said opposed arcuate end walls within said orifice stretching and conforming to the opposed rounded minor surfaces of said cable so as to provide a watertight interference fit entirely about said cable.
Claim 3
Dependent Claim
40 words
The cable and sealing element of claim 1 wherein each of said opposed arcuate end walls has a predetermined radius R2 and each of said opposed involute walls has a predetermined radius R3, and wherein R3 is greater than R2.
Claim 4
Dependent Claim
19 words
The cable and sealing element of claim 1 wherein said orifice extends through the length of said elongated body.
Claim 5
Dependent Claim
22 words
The cable and sealing element of claim 1 further comprising a flange extending about the circumference of one of said elongated body.
Claim 6
Dependent Claim
16 words
The cable and sealing element of claim 1 wherein said orifice terminates within said elongated body.
Claim 7
Dependent Claim
15 words
The cable and sealing element of claim 1 wherein said resilient material is EPDM rubber.
Claim 8
Dependent Claim
20 words
The cable and sealing element of claim 1 further comprising a peripheral shoulder about the periphery of said elongated body.
Claim 9
Dependent Claim
41 words
The cable and 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
20 words
The cable and sealing element of claim 1 further comprising sealing rings formed in the inner surface of said orifice.
