FIG. 8A is an overall view, and FIG. 8B is a detailed view of the connector 82. The surface mount type has a structure in which the land provided on the surface of the substrate 85 and the connector terminal 84 are electrically connected with the front end of the connector terminal 84 along the surface of the substrate 85. In the insertion mounting type, the connector terminal 74 protrudes on the back surface of the connector placement surface, and thus electronic components cannot be mounted on the back surface of the connector placement surface. In the surface mounting type, the connector terminal 84 does not protrude on the back surface of the connector arrangement surface, so that an electronic component can be mounted on the back surface side.

  In Patent Document 1, by inserting and arranging the tip portion of the connector terminal into the non-through hole, the connector terminal does not protrude from the back surface of the board. Therefore, electronic components are mounted on the back side of the connector placement surface of the board. It is disclosed that this is possible. The insertion mounting portion is electrically connected to a corresponding land provided around the non-through hole wall surface and the non-through hole opening of the substrate after being inserted and arranged in the non-through hole.

Accordingly, it is disclosed that an electronic component is also mounted on the back surface of the substrate. Since the connector is a surface mount type in which a plurality of terminals are arranged on the housing, the connector terminals do not protrude from the back surface of the substrate.

The shape is such that at least one electronic component to be mounted on the substrate can be arranged in a space surrounded by the connector main body, the plurality of connector terminals, and the substrate. Therefore, an electronic control device with high mounting efficiency can be provided.

  FIG. 1 is an explanatory diagram of an electronic control device 1 using a connector 2 according to an embodiment of the present invention. The electronic control device 1 includes a connector 2, a substrate 6 on which the connector 2 is mounted, and an electronic component 5. The connector 2 is an insertion mounting type connector constituted by a connector body 3 and connector terminals 4. Here, the mounting procedure of the insertion mounting type connector 2 will be described. The substrate 6 is provided with a through hole 7 that is a through hole. The connector terminal 4 is arranged in a state of passing through the through hole 7. The connector terminal 4 penetrating the through hole 7 is electrically connected to the land provided around the wall surface of the through hole 7 and the opening of the through hole 7.

  The shape of the connector terminal 4 is a shape in which the electronic component 5 can be arranged in a space surrounded by the connector body 3, the plurality of connector terminals 4, and the substrate 6 on which the connector 2 is mounted. The connector terminal 4 shown in FIG. 1 extends from the surface of the connector main body 3 facing the substrate 6, but is not limited to this. When the surface of the connector body 3 facing the substrate 6 is the bottom surface of the connector body 3 (hereinafter referred to as “bottom surface”), the connector terminal 4 extends from the side surface of the connector body 3 rising from the periphery of the bottom surface. May be. In this case, since the connector terminal 4 is not taken out between the connector body 3 and the board 6, the space for arranging the electronic component 5 can be widened. Such a configuration is effective when an electronic component having a volume in the height direction is arranged with reference to the mounting surface of the substrate 6.

  The connector terminal 4 extends in two directions symmetrically with respect to the center line of the connector 2 perpendicular to the mounting surface of the substrate 6, but is not limited thereto. For example, the connector terminal 4 may extend in four directions and the connector terminal 4 may be disposed around the electronic component 5 or, if the problem of strength is solved, the connector terminal 4 extends in one direction on either side. Things can be used. By extending the connector terminals 4 together in one direction, the space for arranging the electronic components 5 can be increased.

  The bent portion of the connector terminal 4 shown in FIG. 1 is a right angle bend. However, when the connector 2 is arranged, it is not limited to the right angle bend if there is a space limitation such as interference with other electronic components. The connector terminal 4 may be bent obliquely or provided with a bend R.

Such an electronic control device 1 is, for example, a vehicle engine ECU (Electric Control).
Unit) is adopted as an electronic control device. The electronic component 5 is, for example, a microcomputer, a transistor, a capacitor, a resistor, or the like, and is preferably mounted before the connector 2 is mounted on the substrate 6.

  FIG. 2 is an explanatory diagram of an electronic control device 11 using a connector 12 according to another embodiment of the present invention. The connector 12 is a surface mount type connector. Here, the mounting procedure of the surface mount connector 12 will be described. The surface-mounted connector 12 has the tip of the connector terminal 14 along the surface of the substrate 15 to electrically connect the land provided on the surface of the substrate 15 and the connector terminal 14. When the number of the connector terminals 14 increases and the connector 12 becomes larger, a space in which the electronic component 5 between the connector main body 13 and the substrate 15 can be arranged can be widened. If all the electronic components 5 mounted on the board 15 have a shape that can be disposed in the space between the connector body 13 and the board 15, the board 15 has a mounting surface on which the connector 12 can be mounted. Therefore, it is possible to further improve the mounting efficiency and downsizing of the engine ECU.

  Since the connector terminal 4 protrudes from the through hole 7 on the back surface of the insertion mounting type connector 2, the electronic component 5 cannot be mounted on the back surface side of the through hole 7 formation site. In the case of the surface mount type connector 12, since the connector terminal 14 does not protrude from the back surface of the substrate 15, the electronic component 5 can be mounted on the back surface of the substrate 15. The connector terminal 14 shown in FIG. 2 extends from the bottom surface of the connector main body 13, but is not limited to this, and the bent portion of the connector terminal 14 is not limited to the right angle bend shown in FIG. 2.

For example, the cross section in which both end portions of the noise reduction member 42 are raised in the direction of the substrates 6 and 15 may be U-shaped. If the electronic control devices 41 and 51 are vehicle engine ECUs, the noise reduction member 42 is attached to reduce the influence of the electromagnetic waves generated by the electronic control devices 41 and 51 on other in-vehicle electronic devices. Since the noise reduction member 42 is attached to the metallic connector terminals 4 and 14, a portion in contact with the connector terminals 4 and 14 is formed of an insulating material.
