An object of the present invention is to provide an electronic control unit that curbs overflow of a sealant at a three-way junction of the sealant in the vicinity of a connector. The electronic control unit includes a first seal partthat seals between a base memberand a cover member, a second seal partthat seals between the base memberand a connector housing, and a third seal partthat is connected to the first seal partand the second seal partand seals between the cover memberand the connector housing. In a part (three-way junction) where the first seal part, the second seal part, and the third seal partintersect, a space partJAthat is connected to the recessed partand recessed further from a surface forming the recessed partis formed.

Electrical control unit with sealant between a cover, a base, and an electrical connector

Provided is an in-vehicle control device () including: a base (); a cover () fixed to the base; a circuit board () housed in the base and the cover; and an electronic component () mounted on the circuit board, in which the base is made of a steel plate material, and includes a plate-shaped main body portion (), a bottomed cylinder () having a U-shaped cross section in which one of front and back surfaces of the main body portion is recessed and protrudes to the other side, and a screw portion () provided on a peripheral surface of the cylinder, and the circuit board is fastened to the base by a fastening member () screwed into the screw portion of the cylinder.

In-vehicle control device and manufacturing method

An electronic control device includes a housing including a first region in which heat dissipation fins are formed on one side and an electronic component generating the largest amount of heat is in thermal contact with the other side, and a second region in which an electronic component is in thermal contact with the one side and the other side.

Electronic control device

An electronic device maintains a pressure adjustment function of a breathable filter. The electronic device includes a connector that includes a connector housing that closes an opening portion of a housing accommodating a circuit board and holds a connection terminal enabling electric connection of the circuit board to an external connector and a communication hole that penetrates the connector housing and allows an internal space and an external space of the housing to communicate with each other, and a filter attached to the connector housing to cover a first opening that opens in the communication hole on an internal space side of the housing. The connector housing has a shielding wall surrounding the periphery of the second opening of the communication hole that opens to the external space side of the housing and protrudes toward the external space side of the housing from the second opening of the communication hole.

Electronic device for resisting high-pressure liquid with breathable filter

An electronic control unit () includes a connector (), the connector includes a connector main body () and a plurality of terminals (), the connector main body includes an attachment surface () and a seal arrangement portion () on a surface (), the seal arrangement portion includes a first seal arrangement portion () formed in an arrangement direction of the terminals, and a second seal arrangement portion () that is continuous with both end portions () of the first seal arrangement portion and is inclined toward the electronic control board side as it goes toward the other end side facing one end side of an electronic control board (), the first seal arrangement portion includes a plurality of predetermined portions () formed so as to be directed toward the electronic control board side from a center side of the first seal arrangement portion toward both end sides of the first seal arrangement portion at both end portions of the first seal arrangement portion, the cover () includes a plurality of bent portions () formed so as to be directed toward the electronic control board side from a center side of the cover toward both end sides of the cover, and each of the predetermined portions is in contact with each of the bent portions.

Electronic control unit

To make it possible to enhance waterproofness of a vent hole when an electronic controller is mounted on an automobile. The electronic controller includes a waterproof case that accommodates a printed circuit board with electronic parts mounted thereon, and a connector that electrically connects the printed circuit board and an external apparatus to each other, the electronic controller being mounted on the automobile in a posture having the connector directed downward. The waterproof case has an inclined surface that is smaller as the distance from a bottom surface is more on the connector side, and the inclined surface is formed with a vent hole that is closed with the breathing filter.
