CPC H01R 4/72 (2013.01) [B29C 65/4815 (2013.01); H01R 43/00 (2013.01); H02G 15/04 (2013.01)] | 13 Claims |
1. A sealing device for sealing an electrical terminal, comprising:
a heat shrinkable tubing having an inner wall;
a first sealant/adhesive configured to cooperate with the heat shrinkable tubing, the first sealant/adhesive having a first sealant/adhesive first surface and an oppositely facing first sealant/adhesive second surface, the second surface of the first sealant/adhesive being ultra-sonically bonded to the inner wall of the heat shrinkable tubing prior to placement of the sealing device over the electrical terminal, the first sealant/adhesive has a first viscosity;
a second sealant/adhesive configured to cooperate with free ends of electrical conductors which are in electrical engagement with the electrical terminal, the second sealant/adhesive having a second sealant/adhesive first surface and an oppositely facing second sealant/adhesive second surface, the second sealant/adhesive first surface provided in engagement with the electrical conductors, the second sealant/adhesive second surface provided in engagement and bonded with the first sealant/adhesive first surface, the second sealant/adhesive having a second viscosity which has a lower viscosity than the first sealant/adhesive;
the first sealant/adhesive having a melting point which is below the melting point of the second sealant/adhesive; and
a third sealant/adhesive provided proximate the first sealant/adhesive the third sealant/adhesive configured to cooperate with the electrical conductors, the third sealant/adhesive having a third sealant/adhesive first surface and an oppositely facing third sealant/adhesive second surface, the third sealant/adhesive first surface provided in engagement with the electrical conductors, the third sealant/adhesive having a third viscosity which is higher than the first viscosity of the first sealant/adhesive which, upon application of heat, allows the third sealant/adhesive to melt and conform to a surface of the electrical conductors without significantly flowing from a designated region of the electrical conductors.
