    • PROBLEM TO BE SOLVED: To provide an electromagnetic contactor capable of improving productivity, simplifying a brazing jig, and also restraining flatness or warpage of a plate part supporting a stationary contact.SOLUTION: The electromagnetic contactor is provided with an arc-extinguishing chamber 102 for housing a contact mechanism 101 having a pair of stationary contacts 111, 112 and a movable contact 130 contacting the pair of stationary contacts inside. The arc-extinguishing chamber 102 has through holes 105, 106 fixing at least the pair of stationary contacts, and a flat plate-like stationary contact supporting insulation substrate 105, on which a metallic foil is formed on an outer peripheral edge on one face by metallization processing. The stationary contacts 111, 112 and a metallic cylinder body 104 are soldered to the metallic foil of the stationary contact supporting insulation substrate 105. An insulation cylinder body 140 is arranged on inner periphery of the metallic cylinder body 104.
    • 要解决的问题:提供一种能够提高生产率的电磁接触器,简化钎焊夹具,并且还抑制支撑固定接触的板部件的平坦度或翘曲。 解决方案:电磁接触器设置有灭弧室102,用于容纳接触机构101,接触机构101具有一对固定触头111,112和与该对固定触头内部接触的可动触头130。 灭弧室102具有固定至少一对固定触点的通孔105,106和平板状的固定触点支撑绝缘基板105,金属箔在其一面的外周边缘上形成有金属箔, 金属化处理。 固定触头111,112和金属筒体104被焊接到固定触头支撑绝缘基板105的金属箔上。绝缘筒体140设置在金属筒体104的内周上。 C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a circuit breaker including an arc-extinguishing unit capable of preventing debris generated due to arc from being spread in the circuit breaker and adhering the debris on grids as much as possible.SOLUTION: A circuit breaker includes: a case; a switching mechanism 400 provided in the case to open or close an electrical path; and a movable contact terminal 500 and a stationary contact terminal 600 that are provided in the case. The circuit breaker has an arc-extinguishing unit 700 including: a pair of side plates 720 facing each other and spaced apart from each other; at least one first grid 730 arrayed between the side plates 720 and spaced apart from one another with a predetermined interval; and a second grid 710 coupled to upper ends of the side plates 720, spaced apart from the first grid 730, and bent with a predetermined angle toward the movable contact terminal 500.
    • 要解决的问题:提供一种断路器,其包括灭弧单元,其能够防止由于电弧而产生的碎屑扩散到断路器中并尽可能地将碎屑粘附在网格上。 解决方案:断路器包括:壳体; 设置在壳体中以打开或关闭电路径的切换机构400; 以及设置在壳体中的可动接触端子500和固定接触端子600。 断路器具有灭弧单元700,其包括:一对侧板720,彼此面对并且彼此间隔开; 排列在侧板720之间并以预定间隔彼此间隔开的至少一个第一格栅730; 以及耦合到侧板720的上端的第二格栅710,与第一格栅730间隔开,并且朝着可动接触端子500以预定角度弯曲。版权所有(C)2012,JPO和INPIT
