Abstract
Provided is a highly reliable electronic control device which has not only an effect of reducing costs but also an effect of facilitating a manufacturing process. To include a control board; a connector including a terminal connected to the control board; and a housing case to which the control board and the connector are fixed. The control board has a part sealed with a sealing resin. The connector is disposed at a position facing another part of the control board, being isolated from the sealing resin by the control board and the housing case.
Claims13
An electronic control device comprising:
- a control board that has a part sealed with a sealing resin;
- a connector that is disposed at a position facing another part of the control board and includes a terminal connected to the control board;
- a housing case to which the control board and the connector are fixed, wherein the housing case includes:
- a first frame which surrounds the connector and comes into contact with the control board, and
- a second frame which comes into contact with the control board outside the first frame;
- a first resin-unsealed space formed by the control board, the housing case and the connector, wherein the first resin-unsealed space is not being sealed with the sealing resin;
- a second resin-unsealed space which is not affected by an ingress of the sealing resin between the housing case, the second frame, and the control board;
- and
- an adhesive seal material at contact portions between the first frame and the control board, and the second frame and the control board;
- wherein the connector is isolated from the sealing resin by the control board and the housing case.
An electronic control device comprising:
- a control board that has a part sealed with a sealing resin;
- a connector hat is disposed at a position facing another part of the control board and includes a terminal connected to the control board;
- and
- a housing case to which the control board and the connector are fixed, wherein the housing case includes
- a first frame which surrounds the connector and comes into contact with the control board, and
- a second frame which comes into contact with the control board outside the first frame;
- a resin-unsealed space formed from the control board, the housing case and the connector, wherein the resin-unsealed space not being sealed with resin;
- an adhesive seal material at contact portions between the first frame and the control board, and the second frame and the control board,
- wherein the connector is isolated from the sealing resin by the control board and the housing case.
An electronic control device comprising:
- a housing case to which a control board and a connector are fixed, wherein the housing case includes:
- a first frame which surrounds the connector and comes into contact with the control board, and
- a second frame which comes into contact with the control board outside the first frame;
- a first resin-unsealed space formed by the control board, the housing case and the connector, wherein the first resin-unsealed space is not being sealed with a sealing resin;
- an adhesive seal material at contact portions between the first frame and the control board, and the second frame and the control board;
- a connector holding unit provided with a gap between the connector and the control board so as to hold the connector in the housing case;
- and
- a resin-ingress prevention unit which cooperates with the control board to prevent ingress of the sealing resin into the gap,
- wherein the connector is isolated from the sealing resin by the control board and the housing case.
