Title (EN) POLYMERIC POSITIVE TEMPERATURE COEFFICIENT DEVICE FOR SEAT MOTOR PROTECTION
(FR) DISPOSITIF POLYMÈRE À COEFFICIENT DE TEMPÉRATURE POSITIF POUR PROTECTION DE MOTEUR DE SIÈGE
Abstract:
(EN) A positive temperature coefficient (PTC) device including a protection component (102), such as a polymeric PTC chip,a first terminal (108) and a second terminal (110) coupled to opposite sides of the protection component (102). The PTC device further includes a component housing (106) surrounding the protection component (102) and the terminals (108, 110),wherein the component housing (106) includes a first end (114) and a second end (116),and wherein the first and the second terminals (108, 110) extend through an end wall (144) of the second end (116). each of the first and second terminals (108, 110) includes a main body (156) and a terminal arm (158) extending from the main body (156),wherein the terminal arm (158) extends through the end wall (144) of a closed end of the component housing (106),and wherein the main body (156) is enclosed by the component housing (106).
(FR) L'invention concerne un dispositif à coefficient de température positif (PTC) comprenant un composant de protection (102), tel qu'une puce PTC polymère, une première borne (108) et une seconde borne (110) couplées à des côtés opposés du composant de protection (102). Le dispositif PTC comprend en outre un boîtier de composant (106) enveloppant le composant de protection (102) et les bornes (108, 110), le boîtier de composant (106) comprenant une première extrémité (114) et une seconde extrémité (116), et les première et seconde bornes (108, 110) s'étendant à travers une paroi d'extrémité (144) de la seconde extrémité (116). Chacune des première et seconde bornes (108, 110) comprend un corps principal (156) et un bras de borne (158) s'étendant à partir du corps principal (156), le bras de borne (158) s'étendant à travers la paroi d'extrémité (144) d'une extrémité fermée du boîtier de composant (106), et le corps principal (156) étant enveloppé par le boîtier de composant (106).
