Abstract: front page image
(EN)A contact (44), comprising a first coiled spring (441), a second coiled spring (442) installed in the hollow part of the first coiled spring (441) and having a length shorter than the length of a wire material forming the first coiled spring (441), and contact parts (443) provided at both ends of the first coiled spring (441) and the second coiled spring (442), whereby, since the contact (44) does not have a probe part and a casing though a probe pin has the probe part and the casing, an inductance component can be decreased and a pitch can be reduced and, since the contact (44) does not use conductive resin material, the contact (44) has an excellent durability.
(FR)Cette invention concerne un contact (44) comprenant un premier ressort (441) enroulé, un second ressort (442) enroulé, placé dans la partie creuse du premier ressort (441) enroulé et présentant une longueur inférieure à celle du fil formant le premier ressort (441) enroulé, ainsi que des pièces de contact (443) placées à chaque extrémité du premier ressort (441) enroulé et du second ressort (442) enroulé. Le fait que ce contact (44) ne comprenne pas de partie sonde et de boîtier bien qu'une borne de sonde comprenne la partie sonde et le boîtier permet de diminuer un composant d'inductance et de réduire une crête, et le fait que ce contact (44) n'utilise pas de matériau de résine conductrice lui confère une excellente durabilité.
