Abstract

L'invention concerne un dispositif de mesure de température. Le dispositif de mesure de température de la présente invention comprend un boîtier, une pluralité de blocs de borne couplés au boîtier, et une carte de circuit imprimé (PCB) de commande principale connectée aux blocs de borne à l'intérieur du boîtier, la pluralité de blocs terminaux comprenant des premier et second blocs de borne sur lesquels est disposée une broche de couplage principale pliée de façon multiple, le second bloc de borne comprenant en outre : une PCB de compensation de température positionnée sur la surface supérieure de la broche de couplage principale ; un capteur de compensation de température couplé sur la surface supérieure de la PCB de compensation de température ; et une broche de sous-couplage couplée sur la surface supérieure de la PCB de compensation de température et connectée électriquement au capteur de compensation de température, une première broche de connexion de la broche de couplage principale et une seconde broche de connexion de la broche de sous-couplage étant connectées électriquement, respectivement, à une pluralité de bornes formées sur la PCB de commande principale. Selon la présente invention, un trou traversant est agencé de manière à chevaucher le capteur de compensation de température, et ainsi un court-circuit entre la broche de couplage principale et la broche de sous-couplage peut être évité à l'avance, et de ce fait la fiabilité du produit peut être améliorée.
