Claims
- 1. An electronic control device comprising:
a board on which electronic parts are provided; and a case member accommodating the board and plural cylindrical coils, the plural cylindrical coils having terminals electrically connected to the board by soldering, wherein an intermediate wall dividing the board from the plural cylindrical coils is formed on the case member, and a stress absorbing means for preventing generation of a solder break on each connection part between the terminals and the board by thermal load is provided between the board and the intermediate wall.
- 2. An electronic control device according to claim 1, wherein the case member is made of a resin material, and the plural cylindrical coils are embedded in the case member by integral molding.
- 3. An electronic control device according to claim 1, wherein the stress absorbing means is formed by bending the terminals.
- 4. An electronic control device comprising:
a board on which electronic parts are provided; a case member accommodating the board and plural cylindrical coils having terminals electrically connected to the board by soldering; an intermediate wall dividing the board from the plural cylindrical coils and formed on the case member; and a stress absorbing means for preventing generation of a solder break on each connection part between the terminals and the board by thermal load, the stress absorbing means being provided between the board and the intermediate wall.
- 5. An electronic control device comprising:
a board on which electronic parts are provided; and a case member accommodating the board and plural cylindrical coils, the plural cylindrical coils having metal terminals electrically connected to the board by soldering, wherein an intermediate wall dividing the board from the plural cylindrical coils is formed on the case member, and a stress absorbing means for preventing generation of a solder break on each connection part between the metal terminals and the board by thermal load is provided between the board and the intermediate wall and made of the metal terminals.
- 6. An electronic control device according to claim 5, wherein the stress absorbing means has several bended parts capable of preventing the solder break.
- 7. An electronic control device according to claim 5, wherein the metal terminals are made of a thin metal plate.
- 8. An electronic control device according to claim 6, wherein the metal terminals are made of a thin metal plate.
- 9. An electronic control device comprising:
a board on which electronic parts are provided; and a case member accommodating the board and plural cylindrical coils, the plural cylindrical coils having terminals electrically connected to the board by soldering, wherein an intermediate wall dividing the board from the plural cylindrical coils is formed on the case member, and a stress absorbing means for preventing generation of a solder break on each connection part between the terminals and the board by thermal load is provided between the board and the intermediate wall and made of the terminals.
