Fuel resistance package

Abstract

A fuel resistance package includes a member to be sealed, which is used in a fuel atmosphere including an aromatic compound or ethanol, and a sealing member, which seals the member to be sealed so that the member to be sealed is protected from fuel in the fuel atmosphere. The sealing member is made of resin containing glycidyl amine-based epoxy resin having a glass-transition temperature of 180° C. or more and a dielectric constant of 3.5 or less as epoxy resin, an amine-based hardener that ring-opens epoxy groups of the epoxy resin to harden the epoxy resin, and filler made of silica.

1 . A fuel resistance package comprising:
 a member to be sealed, which is used in a fuel atmosphere including at least one of an aromatic compound and ethanol; and   a sealing member, which seals the member to be sealed so that the member to be sealed is protected from fuel in the fuel atmosphere, wherein   the sealing member is made of resin containing epoxy resin having a glass-transition temperature of 180° C. or more and a dielectric constant of 3.5 or less, and filler made of silica is contained in the resin.   
     
     
         2 . The fuel resistance package according to  claim 1 , wherein
 the epoxy resin is glycidyl amine-based epoxy resin, and   the sealing member further includes an amine-based hardener that ring-opens an epoxy group of the glycidyl amine-based epoxy resin to harden the glycidyl amine-based epoxy resin.   
     
     
         3 . The fuel resistance package according to  claim 1 , wherein
 the member to be sealed includes:
 a first member; 
 a second member; and 
 a connecting member that electrically connects the first member and the second member, and 
   the connecting member is sealed with the sealing member.   
     
     
         4 . The fuel resistance package according to  claim 1 , wherein
 the member to be sealed includes:
 a first resin portion that is primary molded; and 
 a second resin portion that is secondary molded and located to be in contact with the first resin portion, and 
 a boundary portion between the first resin portion and the second resin portion is sealed with the sealing member. 
   
     
     
         5 . The fuel resistance package according to  claim 4 , wherein
 the member to be sealed further includes:
 a first member; 
 a second member; and 
 a connecting member that electrically connects the first member and the second member, and 
   the connecting member is sealed with the first resin portion.   
     
     
         6 . The fuel resistance package according to  claim 2 , wherein
 the sealing member further includes a coupling agent that ensures a binding property between the filler and the glycidyl amine-based epoxy resin.
