Abstract
An electrical connection is provided for an environment that is subjected to corrosive gases or liquids. An outer insulating layer is formed on each of at least two conductors and made up of a fluorinated polymer that is meltable at a temperature situated between the temperature of the environment and a predetermined higher temperature. A heat-shrink sleeve surrounds the conductors and is made up of an outer layer of heat-shrink polymer and an inner layer of the fluorinated polymer that is meltable at a temperature situated between the temperature of the environment and the predetermined higher temperature. A weld is formed by melting the outer insulating layers of the conductors and the inner layer of the heat-shrink sleeve by heating to a temperature higher than the temperature of the environment and lower than the predetermined higher temperature, thereby making a weld that is continuous and leaktight, and of controlled thickness.
