Title
(EN) TEMPERATURE SENSOR WITH ANTI-ROTATION STOP
(FR) CAPTEUR DE TEMPERATURE AVEC BUTEE ANTI-ROTATION
Abstract
(EN)
The present invention relates to a temperature sensor (1) for a motor vehicle, comprising: - a temperature-sensitive element, - two electric wires (3) connecting the temperature-sensitive element to an electrical connector, - an insulating sheath (5) surrounding the two electric wires (3), - a protective end piece comprising a closed end in which the temperature-sensitive element is housed, and - a fixing means (6) through which the insulating sheath (5) passes, said fixing means (6) comprising a threaded element (8) intended to be screwed into a threaded orifice (7) provided in an engine interface element (9) of the vehicle so as to fix the temperature sensor (1) to the engine interface element (9), and a stop (10) fixed to the insulating sheath (5), the stop (10) surrounding the insulating sheath (5) and being intended to provide sealing between the inside of the engine interface element (9) and the outside, the threaded element (8) being able to turn relative to the stop (10). According to the invention, the stop (10) comprises at least one lug (11) intended to be inserted into a slot (12) provided in the engine interface element (9) to block the rotation of the temperature sensor (1) with respect to the engine interface element (9).
(FR)
La présente invention a pour objet un capteur de température (1) pour véhicule automobile comprenant : - un élément sensible à la température, - deux fils électriques (3) reliant l'élément sensible à la température à un connecteur électrique, - une gaine isolante (5) entourant les deux fils électriques (3), - un embout de protection comportant une extrémité fermée dans laquelle est logé l'élément sensible à la température, et - un moyen de fixation (6) traversé par la gaine isolante (5), ledit moyen de fixation (6) comprenant un élément fileté (8) destiné à se visser dans un orifice fileté (7) prévu dans un élément d'interface moteur (9) du véhicule pour fixer le capteur de température (1) à l'élément d'interface moteur (9) et une butée (10) fixée à la gaine isolante (5), la butée (10) entourant la gaine isolante (5) et étant destinée à assurer l'étanchéité entre l'intérieur de l'élément d'interface moteur (9) et l'extérieur, l'élément fileté (8) étant mobile en rotation par rapport à la butée (10). Selon l'invention, la butée (10) comprend au moins un ergot (11) destiné à s'insérer dans une fente (12) prévu dans l'élément d'interface moteur (9) pour bloquer la rotation du capteur de température (1) par rapport à l'élément d'interface moteur (9).
