    • PROBLEM TO BE SOLVED: To provide an airtight structure of a distributed board 1, capable of being switched from an ordinary specification to an airtight specification easily, even after the installation. SOLUTION: In this airtight structure of the distributed board, a base 2 is formed with venting holes 3, and a cover for covering the venting holes 3 is attached. Even after the installation of the distribution board 1, the distribution board 1 can be changed from the ordinary specification to the airtight specification, without the need for troubles, such as additional part replacement work by opening and closing the cover. Trouble for inventory control between the ordinary specification and the airtight specification are eliminated. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:即使在安装之后,也可以容易地提供分布式板1的气密结构,其能够从普通规格到气密规范的切换。 解决方案:在分布板的这种气密结构中,基座2形成有通气孔3,并且安装用于覆盖通气孔3的盖子。 即使在分配板1的安装之后,也可以将分配板1从普通规格变更为气密规格,而不需要诸如打开和关闭盖子的附加零件更换工作等麻烦。 消除了普通规格和气密规格之间库存控制的麻烦。 版权所有(C)2004,JPO

    • PROBLEM TO BE SOLVED: To provide a control panel capable of efficiently cooling the heating of a switching element through which a large current flows. SOLUTION: This control panel is provided with a unit guide 25 whose cross-sectional area is shaped like a U character, which is provided with a front barrier 25D and upper and lower edge guides 25C, and which is mounted on a control panel casing side board 21; a side parting board 26 whose front part is provided with a front opening 26F for parting the unit guide 25 into an accessory vending zone 104 and a main vending zone 103 in which heat sinks 8 and 9 are housed; a front board 27C overlapped with the front parting barrier 25D; and vertical rails 27B engaged with the guide 25C. Also, radiating fins 8B and 9B are faced horizontally, and the heat sinks 8 and 9 are mounted through an insulating frame 28. A box-shaped dust-preventing vending zone is formed in the control panel of the heat sinks 8 and 9 and a unit panel 27 inserted from the front part of the control panel to the guide 25C, and a cooling fan 16 for blasting toward the central parts of base plates 8A and 9A is set at the central part of the backward and forward direction of the side parting board 26.
