Abstract
A device comprises elements for measuring current, the elements being housed in a casing. The casing includes a first portion and a second portion made of plastic, welded to each other, which together define a housing for receiving the measuring elements. The first portion is opaque in order to absorb a laser beam for welding the portions, and the second portion is transparent in order to let the laser beam pass. The process for manufacturing the device includes a fitting step in which the measuring elements are fitted into the casing and an assembly step in which the portions of the casing are joined together using a laser welding process.
