    • The invention provides an electronic control device having a high-grade heat sink that: does not require tight control at the time of manufacturing; is structurally simple; can be produced at a higher production rate; and is cost-effective. In this device, when a circuit board 14 having an electronic component 13 thereon is placed in a non-metal (resin) housing having: a housing base 11 integrally comprising via a partition wall lie a connector inserting section 18 used for electrical connection with an external mating connector (not illustrated); and a housing cover 12 attached to the housing base 11, part of the board 14 is inserted into an insertion hole provided in the partition wall lie so that it is exposed inside the connector inserting section 18. When a convex-shaped metal part 15, used as a heat sink, having a flange 15a on the bottom side is attached from an opening provided in the housing base 11, the top section of the metal part 15 comes into contact with mounting position of the electronic component 13 on the board 14 via a heat dissipating filler material 16, and the flange 15a and the wall section near the opening are brought into contact with each other via a sealing filler material 17.
    • 本发明提供了一种具有高级散热器的电子控制装置,其在制造时不需要严格的控制; 结构简单 可以以较高的生产率生产; 并且具有成本效益。 在该装置中,当其上具有电子部件13的电路板14放置在非金属(树脂)壳体中时,其具有通过分隔壁一体地包括的壳体基座11,用于与电气连接的连接器插入部18 外部配合连接器(未示出); 以及安装在壳体基座11上的壳体盖12,将板14的一部分插入设置在分隔壁11a中的插入孔中,使其暴露在连接器插入部18的内部。当凸形金属部15, 用作散热器的底面上的凸缘15a从设置在壳体基座11中的开口安装,金属部件15的顶部通过电路板13的安装位置与板14上的安装位置相接触,经由 散热填料16,凸缘15a和开口附近的壁部分通过密封填料17相互接触。
