Abstract

La présente invention a pour objet un capteur de température (1) pour véhicule automobile et son procédé de fabrication. Le capteur de température (1) comprend un élément sensible à la température (2) relié à deux premiers fils électriques (3) et une gaine isolante (4) comprenant un cœur minéral entouré par une enveloppe métallique (5). Les premiers fils électriques (3) traversent le cœur de la gaine isolante (4) et ressortent par une extrémité de la gaine isolante (6) pour se connecter à deux deuxièmes fils électriques (7) respectifs reliés à un connecteur électrique. Selon l'invention, le capteur de température (1) comprend un tube (9) comprenant une première partie (10) fixée sur la surface externe de l'enveloppe métallique (5) de la gaine isolante (4) et une deuxième partie (11) entourant l'extrémité de la gaine isolante (6) de façon à former une cavité (12) autour de cette dernière. La cavité (12) est remplie d'un matériau d'étanchéité (13) recouvrant l'extrémité de la gaine isolante (6).The present invention relates to a temperature sensor (1) for a motor vehicle and its manufacturing process. The temperature sensor (1) comprises a temperature sensitive element (2) connected to two first electrical wires (3) and an insulating sheath (4) comprising a mineral core surrounded by a metal shell (5). The first electrical wires (3) pass through the core of the insulating sheath (4) and emerge from one end of the insulating sheath (6) to connect to two respective second electrical wires (7) connected to an electrical connector. According to the invention, the temperature sensor (1) comprises a tube (9) comprising a first part (10) fixed on the outer surface of the metal casing (5) of the insulating sheath (4) and a second part ( 11) surrounding the end of the insulating sheath (6) so as to form a cavity (12) around the latter. The cavity (12) is filled with a sealing material (13) covering the end of the insulating sheath (6).
