Abstract

To provide an electronic control device capable of securing electromagnetic compatibility and mechanical strength. An electronic control device includes a base portion formed in a bottomed cylindrical shape; an electronic control board provided in the base portion; and connectors provided on an opening side of the base portion and electrically connected to the electronic control board, in which the base portion includes a first layer formed of a conductive member and a second layer formed of a member different from that of the first layer.

First claim

The invention claimed is:

1. An electronic control device comprising:
a base portion formed in a square tubular shape;
an electronic control board provided in the base portion;
a connector provided on an opening side of the base portion and electrically connected to the electronic control board; and
an attachment portion comprising an insulating member made of an insulating material and formed to protrude outward from an outer side surface of the base portion and attached to an other device, wherein the attachment portion comprises a plurality of conductive protrusions formed of a conductive material that extends into the insulating material, the insulating member having two side walls and a through hole for attaching to the other device, wherein the plurality of conductive protrusions are provided within a width of the insulating member,
wherein the base portion includes at least one first layer formed of a conductive member, and
at least one second layer formed of a member different from that of the first layer.

2. The electronic control device according to claim 1 ,
wherein the second layer is formed of a resin member that is mechanically stronger than the conductive member.

3. The electronic control device according to claim 1 ,
wherein the second layer is clamped between two or more of the at least one first layer.

4. The electronic control device according to claim 1 , wherein
the plurality of conductive protrusion protrude outward from the side surface,
each of the plurality of conductive protrusions includes an inclined surface, and
the inclined surface is located on a far-side rotation direction of a hole within the attachment portion.

5. The electronic control device according to claim 1 , wherein the plurality of conductive protrusions have a trapezoidal shape.

6. An electronic control device comprising:
a base portion formed in a square tubular shape;
an electronic control board provided in the base portion;
a connector provided on an opening side of the base portion and electrically connected to the electronic control board; and
an attachment portion comprising an insulating member made of an insulating material and formed to protrude outward from an outer side surface of the base portion and attached to an other device,
wherein the attachment portion includes
a first attachment portion comprising a plurality of conductive protrusions formed of a conductive material,
a second attachment portion formed of a member different from that of the first attachment portion and comprising an insulating member made of an insulating material and formed to protrude outward from an outer side surface of the base portion and attached to an other device,
wherein the plurality of conductive protrusions extends into the insulating material, the insulating member having two side walls and a through hole for attaching to the other device, wherein the plurality of conductive protrusions are provided within a width of the insulating member.

7. The electronic control device according to claim 6 ,
wherein the second attachment portion is formed of a resin member that is mechanically stronger than the conductive member.

8. The electronic control device according to claim 6 ,
wherein the second attachment portion is attached to the other device, and
a stopper with which the first attachment portion and the second attachment portion are engaged is formed.

9. The electronic control device according to claim 6 , wherein
the plurality of conductive protrusion protrude outward from the side surface,
each of the plurality of conductive protrusions includes an inclined surface, and
the inclined surface is located on a far-side rotation direction of a hole within the attachment portion.

10. The electronic control device according to claim 6 , wherein the plurality of conductive protrusions have a trapezoidal shape.

11. An electronic control device comprising:
a base portion formed in a square tubular shape;
a cover portion formed to cover an opening of the base portion;
an electronic control board provided in the base portion;
an attachment portion comprising an insulating member made of an insulating material and formed to protrude outward from an outer side surface of the base portion and attached to an other device, wherein the attachment portion comprises a plurality of conductive protrusions formed of a conductive material that extends into the insulating material, the insulating member having two side walls and a through hole for attaching to the other device, wherein the plurality of conductive protrusions are provided within a width of the insulating member; and
a connector provided on an opening side of the base portion and electrically connected to the electronic control board,
wherein the cover portion includes
at least one first cover portion formed of a conductive member, and
at least one second cover portion formed of a member different from that of the least one first cover portion.

12. The electronic control device according to claim 11 ,
wherein the second cover portion is formed of a resin member that is mechanically stronger than the conductive member.

13. The electronic control device according to claim 11 ,
wherein the base portion includes a conductive layer formed of the conductive member, and
the first cover portion includes a third cover portion formed toward a bottom portion side of the base portion.

14. The electronic control device according to claim 11 ,
wherein the second cover portion is clamped between two or more of the least one first cover portion.

15. The electronic control device according to claim 11 , wherein
the plurality of conductive protrusion protrude outward from the side surface,
each of the plurality of protrusions includes an inclined surface, and
the inclined surface is located on a far-side rotation direction of a hole within the attachment portion.
