要約
(EN)
Provided is a temperature sensor wherein the breaking strength of a weld between the element electrode wire and the sheath core wire is improved. In the temperature sensor, viewing the weld from the direction wherein the contact between the element electrode wire and the sheath-core wire can be seen, the midpoint of a line connecting the point nearest to and the point farthest from the temperature-sensing part on the weld surface is determined. In the cross-section that passes through the midpoint of the weld cross-sections that are perpendicular to the axial direction of the sheath member, the diameter of the element electrode wire is called D, and a point that is the intersection of the weld and the circumference of the element electrode wire and is nearer the side from which the laser beam is applied is called the first weld point. Drawing the pre-weld circumference (called "virtual circumference" hereafter) of the element electrode wire on the weld and advancing on the weld along the virtual circumference from the first weld point, the point at which the weld and the virtual circumference intersect is called the second weld point. When the length of a line connecting the first and second weld points is called L, the temperature sensor is characterized in that L/D ≧ 0.6.

L'invention concerne un capteur de température avec une plus grande résistance à la rupture d’une soudure entre le fil d’électrode d’élément et le fil de noyau d'enveloppe. Dans le capteur de température, en regardant la soudure de la direction de contact entre le fil d’électrode d’élément et le fil de noyau d'enveloppe, on détermine le point médian d’une ligne connectant le point le plus proche et le point le plus éloigné de la partie détection de la température à la surface de soudure. Dans la coupe transversale passant à travers le point médian des coupes transversales de soudure qui sont perpendiculaires à la direction axiale de l’élément enveloppe, le diamètre du fil d’électrode d’élément est appelé D, et un point correspondant à l’intersection de la soudure et la circonférence du fil d’électrode d’élément et plus proche du côté depuis lequel on applique le faisceau laser, s’appelle premier point de soudure. En traçant la circonférence de pré-soudure (désignée ensuite “circonférence virtuelle") du fil d’électrode d’élément sur la soudure et en progressant sur la soudure le long de la circonférence virtuelle en partant du premier point de soudure, le point auquel la soudure et la circonférence virtuelle se coupent s’appelle second point de soudure. Lorsque la longueur d'une ligne connectant le premier point de soudure et le second point de soudure est appelée L, le capteur de température est caractérisé en ce que L/D ≧ 0,6

 温度センサに関して、素子電極線とシース芯線との溶接部の破断強度を向上させた温度センサを提供することを目的とする。温度センサにおいて、素子電極線とシース芯線との接触部が見える方向から溶接部を見て、溶接部表面における感温部に最も近い地点と、最も遠い地点とを結ぶ線分の中心点を定め、シース部材の軸線方向と直交する溶接部断面のうち、中心点を通る断面において、素子電極線の直径をDとし、溶接部と素子電極線の円周との交点であって、レーザービームを照射した側に近い地点を第1溶接点とし、溶接部に素子電極線の溶接前の円周(以下「仮想円周」という。)を引き、第1溶接点から仮想円周の円周上に沿って溶接部を進み、溶接部と仮想円周が交わる地点を第2溶接点とし、第1溶接点と第2溶接点を結ぶ弦の長さをLと規定した場合に、L/D≧0.6であることを特徴とする。
