摘要： PROBLEM TO BE SOLVED: To provide an arc extinguishing device capable of extinguishing an arc not only at a high-current zone but also at a low-current zone by improving an arc extinguishing performance. SOLUTION: A grid 110 having grid channels 111a, 111b and an arc extinguishing member 120 having arc extinguishing member channels 121a, 121b are alternately arrayed at a given interval in a moving direction of a movable electrode. The movable electrode is made to pass the grid channels 111a, 111b and the arc extinguishing member channels 121a, 121b sequentially at open channels. Narrow grooves 112a, 112b are formed at the innermost part of the grid channels 111a, 111b. When the channels are opened, the arc is attracted and fixed to (restrained by) the narrow grooves 112a, 112b. Especially, by restraining the arc of the low-current zone in the circuit interrupter 100, a contact time of the arc with an arc extinguishing decomposition gas generated from the arc extinguishing member 120 is secured. As a result, an arc of the low current zone can also be promptly extinguished. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a link device capable of easily changing the turning position of a follower, and to reduce the cost. SOLUTION: A square shaft position changing plate 23 is fitted to a crank lever 17 which is a driver in an attachable/detachable manner, and an oscillation through hole in which a first oscillation shaft 20 is inserted is formed off-centered in the shaft position changing plate 23. The position of the first oscillation shaft 20 to the crank lever 17 is changed at four locations and the rotation starting position and the rotation stopping position of a pointer 13 are changed at four locations by changing the fitting direction of the shaft position changing plate 23 at four locations. The indicating position of the pointer 13 can be changed to four locations by one member. The indicating position of the pointer 13 can be changed by removing only one oscillation shaft 20, and the workability in changing the indicating position of the pointer 13 can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a fixed electrode for a switch that eliminates, with a small space, an excess turning part due to play of an opening/closing mechanism part to an introduction position of a fixed contact of a movable contact blade, and can contribute to miniaturization. SOLUTION: A buffer member 42 is provided so as to cross an extension line of an introduction locus of the movable contact blade 19. The buffer member 42 is disposed between both fixed contacts 31 and 31 and near the tip of the movable contact blade 19 at the introduction position. The buffer member 42 is made of synthetic resin material such as EPR having insulating property and elasticity. Therefore, in introduction, the tip of the movable contact blade 19 collides against the upper surface of the buffer member 42. Therefore, overrun of the movable contact blade 19 in the introduction is prevented, and the movable contact blade 19 does not turn largely beyond the introduction position. Since the buffer member 42 is made of the elastic material, impact of the movable contact blade 19 in the introduction can be moderated.

摘要： PROBLEM TO BE SOLVED: To provide a switch in which the occurrence of an arc between a terminal and a contact piece at an instant when a moving contact blade is inserted into a fixed contact can be prevented. SOLUTION: One pair of right and left contact pieces 18a, 18b are put in facing contact with the side faces of a terminal 17 constituting fixed electrodes 14a, 14b. A bypass plate 19 is put in contact with the outer side faces of both contact pieces 18a, 18b. The bypass plate 19 is formed by bending forming a copper plate into U-shaped in a cross section, the inner side faces 20 thereof are put in facing contact with the contact pieces 18a, 18b, and the bottom face 21 is in a facing contact state with the terminal 17. The bottom face 21 of the bypass plate 19 and the terminal 17 are put in facing contact with each other so as not to part by the screwing of a screw 22. The contact pieces 18a, 18b and the terminal 17 are bypass-connected by the bypass plate 19 so that current flowing between the contact pieces 18a, 18b and the terminal 17 mainly flows in the bypass plate 19.

摘要： PROBLEM TO BE SOLVED: To provide a switch contained in a case in which the splash of the fragments of inside structures and the like can be surely prevented even if a bursting cover is significantly deformed as maintaining predetermined bursting performance in bursting. SOLUTION: By fitting a splash prevention plate 41 to a bursting cover 15, the splash prevention plate 41 moves always integrally with the cover 15 as following the deformation of the cover 15. That is, the splash prevention plate 41 and the rear face of the cover 15 stay always in a coupling state. Thereby, the splash prevention plate 41 can deal with the gap formed between the cover 15 and a case 11 so that the splash of the fragments of inside structures from the case 11 can be surely prevented by the splash prevention plate 41.

摘要： PROBLEM TO BE SOLVED: To provide a fixing structure of a terminal cover support member capable of improving efficiency of a work for attaching the support member. SOLUTION: An engagement structure 41 for fixing a terminal cover support member 14 to a terminal portion 32 disposed on an electrical wire connecting side of an electrically conductive bar 13 is provided so as to engage the support member 14 with the engagement structure 41. Therefore, the support member 14 is engaged with the terminal portion 32 by inserting the support member 14 into the terminal portion 32 and pushing the support member 14 on the side of an electrically conductive portion 31. Accordingly, the support member 14 can be easily attached to the terminal portion 32 of the conductive bar 13, and can improve efficiency of an assembling work of a bushing 10. The number of man-hours of the work for attaching the support member 14 to the conductive bar 13 can be reduced because a work for bolt fastening or pin clasping etc. is not required.

摘要： PROBLEM TO BE SOLVED: To provide a bursting structure for a switch capable of suppressing an infiltration of foreign substances such as rain or dust into a body case after pressure is released. SOLUTION: A pressure-release lid 21 is turnably supported in upwardly opening direction to the outer surface of the sidewall of a body case 12, and that pressure-release lid 21 is always biased in a direction in which a pressure- release hole 14 is closed by elastic force of a helical torsion spring 32. The pressure-release hole 14 is held in a position where the pressure-release hole 14 is closed through the engagement of a latched member 34 with a latching member 15. When internal pressure is increased, the engagement of the latched member 34 with the latching member 15 is released, and the pressure-release lid 21 turns in the upwardly opening direction against the elastic force of the helical torsion spring 32. As a result, the pressure-release hole 14 is opened, and thus the internal pressure of the body case 12 is released. After the pressure is released, the pressure-release lid 21 is actively turned, in a direction in which the pressure-release hole is closed by the elastic force of the helical torsion spring 32. This turning is limited by contact of the latched member 34 with the latching member 15. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide an arc-extinguishing device enhancing arc-extinguishing performance. SOLUTION: This arc-extinguishing device 30 of a switch is constituted by stacking a plurality of grids 40 each having a notch 41 through which a moving electrode is passed at specified intervals. Each partition member 50 is interposed between a pair of grids 40. The partition member 50 is made of a synthetic resin member having insulating and arc-extinguishing properties, and has a notch 51 through which the moving electrode is passed. An arc generating between a fixed electrode 15 and the moving electrode when a circuit is opened is driven away toward the deepest part between grids 40 so as to detour round the partition members 50. An arc route is made zigzag. The travelling distance of the arc is extended and arc-extinguishing performance is enhanced. COPYRIGHT: (C)2003,JPO
