Abstract:
1. An electrical connection for achieving leaktight electrical linking in an environment that is subjected to corrosive gases or liquids, wherein the connection comprises: two conductors for forming said electrical connection between each other; an outer insulating layer formed on each of said conductors and made up of a fluorinated polymer that is meltable at a temperature situated between the temperature of said environment and a predetermined higher temperature; a heat-shrink sleeve surrounding said conductors and made up of an outer layer of heat-shrink polymer and an inner layer of said fluorinated polymer that is meltable at a temperature situated between the temperature of said environment and said predetermined higher temperature; a weld formed by the melting of said outer insulating layers of said conductors and said inner layer of said heat-shrink sleeve by heating to a temperature higher than said temperature of said environment and lower than said predetermined higher temperature, thereby making said weld continuous and leaktight, and of controlled thickness; and wherein said inner layer of said heat-shrink sleeve is of a thickness that varies from heating and is adapted to zones for filling around an element for connection of said conductors in order to obtain a weld that is continuous and completely leaktight.
