Definitions

  • This invention relates to a sealing member, an assembly for sealing a hollow member, a method of sealing a hollow member, a method of sealing a multiconductor connector and a sealed multiconductor connector.
  • U.S. Patent No. 4,662,692 to Uken et al describes a method of using a layer of gel to seal contact pins.
  • the gel is surrounded on its sides, but not on either face by a container for ease of handling and subsequent to being cured is disposed adjacent a terminal block usable for connecting the electrical contact pins with the block, and such that an opposite exposed face of the gel is not covered by the container which allows the electrical contact pins to be inserted there through so as to pierce through the gel and therefore be capable of making contact on the block side of the gel.
  • U.S. Patent No. 4,875,870 to Hardy et al provides an improved article of the type disclosed by Uken et al for sealing a multiconductor connector in which the gel container is provided with special securement means to improve the compression on the gel and hence improve the seal. It also discloses an article suitable for sealing to contact pins and/or wires, which uses a layer of gel through which holes for the pins and/or wires are preformed, so that the gel is not deleteriously damaged during insertion of the pins and/or wires, the holes sealing up against the wires trailing from the contact pins when the gel is subjected to compression.
  • the contact pins and wires are pierced through the gel and then the gel is compressed. It has been found that if the gel is compressed first and then the contact pins and wires are inserted and adequate seal is not obtained. Further, if one wants to withdraw one or more contact pins, for example for repair, and then reinsert or replace it, the compression on the gel must be released and the gel must then again be compressed to effect a seal around the replaced wire.
  • One aspect of this invention comprises an assembly for sealing an open end of a hollow member having an inner surface and at least one substrate extending thereinto through said open end, which assembly comprises:
  • a sealing member which comprises at least one layer of sealant positioned between two constraining layers and positioned such that said layers extend transversely across the open end of the hollow member;

  • Another aspect of this invention comprises a method of sealing an open end of a hollow member having an inner surface and at least one substrate extending thereinto through said open end, which method comprises:
  • At least one of said constraining layers and/or the means for applying force to the article is sufficiently resilient to accommodate the displacement of sealant as the substrate passes through the sealant layer while maintaining sufficient force on the sealant to maintain it in sealing contact with the inner surface to the hollow member.
  • a further aspect of this invention comprises a preformed sealing member for sealing an open end of a hollow member which comprises a self-supporting article having at least one layer of sealant positioned between two constraining layers, wherein each of said layers has substantially the same lateral dimensions and at least one of said constraining layers comprises a compressible foam.

  • the constraining layers are of a resilient elastomeric material, preferably a compressible foam, which accommodate volume changes of the sealant.
  • the material of the constraining layers is not critical, as long as at least one of the constraining layers and/or the means applying force to the sealant is sufficiently resilient to maintain the sealant in sealing contact with the inner surface of the hollow member.

Abstract

Une extrémité ouverte d'un élement creux (7) est rendue étanche par l'utilisation d'un élément d'étanchéité (20) comprenant une couche de matériau d'étanchéité (26) entre deux couches de retenue (25, 27). Une force est appliquée à l'élément d'étanchéité pour maintenir le matériau d'étanchéité en contact d'étanchéité avec les parois intérieures de l'élément creux. Au moins une des couches de retenue et/ou le dispositif servant à appliquer une force est/sont suffisamment résilient(s) pour supporter les changements de volume du matériau d'étanchéité pendant les fluctuations de température et le déplacement du matériau d'étanchéité quand un substrat est inséré dans l'élément creux à travers l'élément d'étanchéité. Pour faciliter l'insertion du substrat à travers l'élément d'étanchéité, une des couches de retenue, ou les deux, et/ou la couche d'étanchéité peut/peuvent comporter des trous et/ou des fentes (6, 5).
