Abstract

Selon ce procédé, - on fabrique une ébauche (11) en plastique comprenant au moins un orifice (15) s'étendant entre des faces opposées de l'ébauche (11), - on positionne une piste chauffante (12) sur une première face (16) de l'ébauche (11), de façon à faire passer une partie de connexion (18c) de la piste (12), au droit de l'orifice (15), - on positionne, à travers l'orifice (15), un organe de connexion (14) comprenant une extrémité (19) en forme de patte recourbée en crochet et une extrémité de liaison (20), de façon à placer la patte recourbée autour de la partie de connexion (18c) de la piste (12) et laisser l'extrémité de liaison (20) accessible du côté d'une seconde face (17) de l'ébauche, - on pince l'extrémité (19) en forme de patte recourbée autour de la partie de connexion (18c) et on les soude par apport d'énergie électrique, - on surmoule une couche supplémentaire (13).According to this process, - a plastic blank (11) is manufactured comprising at least one orifice (15) extending between opposite faces of the blank (11), - a heating track (12) is positioned on a first face (16) of the blank (11), so as to pass a connection part (18c) of the track (12), in line with the orifice (15), - one positions, through the orifice ( 15), a connection member (14) comprising an end (19) in the form of a hook bent tab and a connecting end (20), so as to place the bent tab around the connection part (18c) of the track (12) and leave the connecting end (20) accessible from the side of a second face (17) of the blank, - the end (19) in the form of a curved tab is clamped around the connection part (18c) and they are welded by supplying electrical energy, - an additional layer (13) is overmolded.
