Sealing member for an entry port
View Patent ↗A sealing member includes an elastomeric interior portion and a rigid exterior portion. At least one passage extends through the elastomeric interior portion from a first end to a second end of the sealing member. The passage is configured to receive at least one longitudinal member therein. The elastomeric interior portion is configured for sealing engagement with the longitudinal member extending therethrough, and the rigid exterior portion is configured for sealing engagement with an entry port of an enclosure.
1. An assembly comprising:
an enclosure having an entry port lined with a pliable gasket having an entry port portion having a width that substantially extends a longitudinal length of the entry port;
a unitary rigid sleeve having an interior circumferential surface and an exterior circumferential surface, the exterior circumferential surface of the sleeve sealingly engaged with the pliable gasket lining the entry port of the enclosure, wherein the exterior circumferential surface of the sleeve includes a first circumferential ridge and a second circumferential ridge thereon, the first and second ridges containing the gasket lining the entry port therebetween, wherein a spacing between the first and second ridges corresponds to the width of the entry port portion of the gasket;
an elastomeric body having an exterior circumferential surface, a first end and a second end, the exterior circumferential surface of the elastomeric body sealingly engaged with the interior circumferential surface of the rigid sleeve; and
at least one passage extending longitudinally through the elastomeric body from the first end to the second end, the at least one passage configured to sealingly engage a component therein.
2. The assembly of claim 1 , further comprising a plurality of passages extending through the elastomeric interior portion from a first end to a second end of the body, each of the plurality of passages configured to receive at least one longitudinal member therein.
3. The assembly of claim 1 , wherein the elastomeric body is press-fit into the rigid sleeve.
4. The assembly of claim 1 , wherein the elastomeric body is attached to the rigid sleeve by one of adhesive, ultra-sonic welding, fusion boding, and interference press fit between the interior circumferential surface of the sleeve and the exterior circumferential surface of the elastomeric body.
5. The assembly of claim 1 , wherein the elastomeric body has a hardness in the range of about 20 to about 90 durometer (Shore ‘A’), and the rigid sleeve has a hardness greater than about 90 durometer (Shore ‘A’).
6. The assembly of claim 1 , further comprising a plug configured for insertion into the at least one passage, the plug configured to block the passage.
7. The assembly of claim 1 , wherein the elastomeric body is a unitary structure.
8. The assembly of claim 1 , wherein the elastomeric body is formed from a material selected from thermoplastic elastomers, thermoplastic vulcanite rubbers, polyurethane foams, reactive polymers, non-reactive polymers, silicones, EPDMs, and soft plastics.
9. The assembly of claim 1 , wherein the rigid sleeve is formed from a material selected from olefins, polyesters, engineering resins, composites, epoxies, and metals.
10. The assembly of claim 1 , wherein a hardness of a material forming the sleeve is about the same as a hardness of a material forming the enclosure.
11. The assembly of claim 1 , wherein a hardness of a material forming the gasket is about the same as a hardness of a material forming the elastomeric body.
