Note that the contact portions 48 of the first-stage terminal 34 and the second-stage terminal 34 are in contact with the lands 20 adjacent in the X direction. Therefore, by adopting the above configuration, it is possible to suppress positional deviation in the X direction while employing the plurality of terminals 34. Thereby, a short circuit between the terminals 34 can be prevented.

  Next, a method for manufacturing the electronic control device 10 will be described with reference to FIGS.

  As shown in FIG. 8, first, the substrate 12 is assembled to the housing 14. The substrate 12 is inserted into the internal space 24 of the housing 14 from the opening 22 with the end opposite to the end where the land 20 is disposed as the head. Then, the substrate 12 is held by the substrate pressing portions 28 and 30. In this embodiment, in this state, a potting material (not shown) for radiating the heat generated by the substrate 12 to the housing 14 is injected into the internal space 24 and cured. At this time, the potting material is injected to a depth that does not cover the land 20 and does not contact the male connector 16. In addition, it replaces with a potting material and the gel material for thermal radiation can also be used. Also. It is good also as a structure which does not use a potting material or a gel material.

  Next, as shown by the white arrow in FIG. 8, the male connector 16 is inserted into the internal space 24 of the housing 14 from the board connecting portion 44 side. In FIG. 8, the housing 14 is not in contact with the opening / closing plate 36. In this state, the opening / closing plate 36 is held by the reaction force of the terminal 34 so that the entire tapered portion 64 protrudes outside the cylindrical portion 40 of the housing 32. Further, the contact portion 48 of the terminal 34 is at an open position farthest from the substrate 12. In this state, the substrate 12 does not reach the substrate connection portion 44 of the terminal 34 in the Y direction.

  From the state of FIG. 8, the male connector 16 is further inserted into the inner space 24. FIG. 9 shows a state where the housing 14 is in contact with the tapered portion 64. When the opening end of the housing 14 comes into contact with the tapered portion 64, the open / close plates 36 on the both surfaces 12 a and 12 b side of the substrate 12 are both pushed down toward the substrate 12 as the male connector 16 is inserted. As the opening / closing plate 36 is pushed down, the terminal 34 is pushed and deformed, and the contact portion 48 approaches the substrate 12. However, in this state, the contact portion 48 is located above the corresponding surfaces 12a and 12b of the substrate 12. Further, the substrate 12 reaches the tip end portion 44 b of the substrate connection portion 44 of the terminal 34, but does not reach the contact portion 48.

  From the state of FIG. 9, the male connector 16 is further inserted into the inner space 24. Then, the opening / closing plate 36 is further pushed down in the direction approaching the substrate 12, and is in the most pushed position (bottom dead center) as shown in FIG. 10 with the housing 14 reaching the upper surface 36 b. In this state, the contact portion 48 contacts the corresponding land 20 of the substrate 12, and the terminal 34 applies a reaction force due to spring deformation to the substrate 12. That is, the contact portion 48 is in the closed position. In the present embodiment, in consideration of manufacturing variations of the terminal 34, the substrate 12, and the land 20, when the portion slightly inside from the end on the male connector 16 side of the land 20 is positioned directly below the contact portion 48, the contact portion 48 is It is designed to be in the closed position.

  Then, from the state of FIG. 10, the male connector 16 is further inserted into the back side of the internal space 24, and the fitting protrusion 26 is fitted into the fitting frame 54. During this time, the contact portion 48 wipes the surface of the land 20. And the electronic control apparatus 10 shown in FIG. 2 can be obtained.

  Next, the effect of the electronic control apparatus 10 described above will be described.

  In this embodiment, the opening / closing plate 36 is provided as a part of the male connector 16, and the opening / closing plate 36 can be slid in a direction approaching the substrate 12 as the male connector 16 is inserted into the housing 14. . In addition, the terminal 34 can be opened / closed with respect to the substrate 12 by pressing the terminal 34 with the opening / closing plate 36. Therefore, it is possible to suppress the plating on the surface of the terminal 34 from being damaged and thereby reducing the electrical connection reliability.

  Moreover, since the opening / closing plate 36 for opening and closing the terminal 34 is provided as a part of the male connector 16, the electronic control device 10 can suppress an increase in the number of parts.

  Further, the terminal 34 and the land 20 are electrically connected in the manufacturing process of the electronic control device 10. Therefore, before connecting the external connector 18, the board connecting portion 44 and the board 12 in the terminal 34 can be protected by the housing 14 and the housing 32 of the male connector 16.

  In the present embodiment, the plate contact portion 50 is located closer to the fixed portion 42 than the contact portion 48 in the Y direction. For this reason, as shown in FIG. 11, the opening / closing plate 36 is pushed down, so that the load acting on the plate contact portion 50 is caused by the fixed portion 42 and the contact portion 48 positioned on both sides of the plate contact portion 50 in the Y direction. And you can share it. Therefore, the load variation on the substrate 12 by the contact portion 48 can be reduced with respect to the variation in the slide amount of the opening / closing plate 36. For example, even if the slide amount is large, the load on the substrate 12 by the contact portion 48 does not become too high. Therefore, the robustness can be improved with respect to the load variation of the contact portion 48. In addition, in FIG. 11, while showing the terminal 23 and the opening-and-closing plate 36 of the one surface 12a side, it has simplified and illustrated. However, the back surface 12b side has the same configuration.

  Further, in this configuration, since the contact portion 48 is located between the tip portion 44b and the open / close plate 36, when plating the terminal 34, the tip portion 44b to a point a little beyond the contact portion 48 is immersed in the plating solution. Just do it. Therefore, it is possible to reduce the plating area in the terminal 34 and reduce the cost.

  In the present embodiment, the housing 32 has a plate insertion hole 52 that penetrates the cylindrical portion 40. Since the opening / closing plate 36 is inserted into the plate insertion hole 52, which is a through hole, the inclination of the opening / closing plate 36 can be suppressed, and the terminal 34 can be brought into contact with high positional accuracy.

  For this reason, the open / close plate 36 is pushed down, whereby the sum of the load acting on the plate contact portion 50 and the load acting on the fixed portion 42 acts on the contact portion 48. Therefore, the load on the substrate 12 by the contact portion 48 can be increased with a small slide amount. 12 also shows the terminal 23 and the opening / closing plate 36 on the one surface 12a side in a simplified manner as in FIG. However, the back surface 12b side has the same configuration.

  In the case of the flat opening / closing plate 36, as shown in FIG. 14, when the housing 14 contacts the tapered portion 64 of the opening / closing plate 36, the opening / closing plate 36 is pushed down in a direction approaching the substrate 12. FIG. 14 shows a state where the opening / closing plate 36 is pushed down and the contact point 48 starts to contact the land 20. At this time, the plate contact portion 50 is displaced toward the front surface 36a in the Y direction from the initial position before the opening / closing plate 36 is pushed down.

  And until the housing | casing 14 reaches the upper surface 36b, the plate contact part 50 is displaced to the front surface 36a side in a Y direction. Further, as shown in FIG. 15, the contact portion 48 wipes the surface of the land 20 until the fitting protrusion 26 of the housing 14 is fitted to the fitting frame 54 of the male connector 16. Since the substrate 12 is displaced relative to the male connector 16 together with the housing 14, the portion of the surface of the land 20 from the start point to the end point shown in FIG. Become.

  Here, reference numeral 76 shown in FIG. 15 is a case contact portion that contacts the case 14 on the surface of the opening / closing plate 36. In FIG. 15, the tapered portion 64 and the upper surface 36 b become the case contact portion 76. ing. Further, reference numeral 78 shown in FIG. 15 is a terminal contact portion that contacts the plate contact portion 50 due to the displacement of the opening and closing plate 36 in the lower surface 36 c of the opening and closing plate 36.

  As shown in FIG. 15, in the flat opening / closing plate 36, the housing contact portion 76 and the terminal contact portion 78 overlap in the Y direction. Therefore, the length of the wine ping part 20a becomes long.

  On the other hand, in this embodiment, without changing the length of the opening / closing plate 36 in the Y direction, the shape of the opening / closing plate 36 defined by the Y direction and the Z direction is substantially L-shaped as shown in FIG. Yes. The initial position of the plate contact portion 50 is set to the bottom side of the housing 14 with respect to the tapered surface 64.

  According to this, as shown in FIG. 17, the housing contact portion 76 and the terminal contact portion 78 do not overlap in the Y direction. Further, the housing contact portion 76 is located closer to the fixed portion 42 than the terminal contact portion 78. Therefore, the length of the winding part 20a can be shortened. That is, in the Y direction, the land 20 and thus the substrate 12 can be reduced in size.

  FIG. 18 shows an example of the opening / closing plate 36 described above. In FIG. 18, a portion corresponding to the upper surface 36 b of the opening / closing plate 36 is extended in the X direction, and a portion protruding in the X direction with respect to the tapered portion 64 is a guide protrusion 80. Reference numeral 82 denotes a guide groove provided in the plate insertion hole 52.

  Further, the shape of the opening / closing plate 36 is not limited to an L shape. The opening / closing plate 36 may be provided so that the housing contact portion 76 and the terminal contact portion 78 do not overlap, and the housing contact portion 76 is closer to the fixed portion 42 than the terminal contact portion 78.

  The configuration shown in the present embodiment can be combined with any of the first to third embodiments.

(Fifth embodiment)
In the present embodiment, description of parts common to the electronic control device 10 shown in the above embodiment is omitted.

  In the present embodiment, as shown in FIG. 19, the housing 32 has a substrate holding portion 84 that holds the substrate 12. The substrate holding part 84 only needs to hold the substrate 12 with at least the terminals 34 in the open position.

  In the example shown in FIG. 19, substrate holding portions 84 are provided at both ends of the housing 32 in the X direction. Each substrate holding portion 84 has a pair of metal spring members 86 shown in FIG. 20 so as to sandwich the substrate 12 therebetween. One end of the spring member 86 is bent into a substantially C shape. Further, the spring member 86 presses the edge of the substrate 12 where the land 20 is not disposed. Reference numeral 88 shown in FIG. 20 is a contact portion of the spring member 86 with the substrate 12.

  The pair of spring members 86 are arranged so that the contact portions 88 face each other, and the interval between the contact portions 88 is set slightly shorter than the thickness of the substrate 12 before the substrate 12 is inserted. For this reason, the board | substrate 12 can be hold | maintained between a pair of spring members 86 with the reaction force by a spring deformation | transformation. In the present embodiment, the board 12 is held by the board holding portion 84 made of the spring member 86 even when the terminal 34 is in the closed position.

  In addition, the code | symbol 90 shown in FIG. 19 is an accommodation hole of the spring member 86 provided in the cylinder part 40 of the housing 32. FIG. Reference numeral 92 is a notch that connects the accommodation hole 90 and the internal space of the cylindrical portion 40 so that the substrate 12 is interposed between the contact portions 88.

  According to this, as shown in FIGS. 21 to 23, the male connector 16 can be assembled to the housing 14 after the substrate 12 is assembled to the male connector 16. As shown in FIG. 21, the board 12 is held (temporarily fixed) to the male connector 16 by the board holding portion 84 made of the spring member 86 before the male connector 16 is assembled to the housing 14. Further, when assembling to the housing 14, until the housing 14 comes into contact with the opening / closing plate 36, as shown in FIG. 22, the contact portion 48 is in the open position, and the substrate 12 is held by the substrate holding portion 84. . When the housing 14 comes into contact with the opening / closing plate 36 and the contact portion 48 is in the closed position as shown in FIG. 23, the substrate 12 is held by the terminal 34 together with the substrate holding portion 84.

  Therefore, even when a potting material or gel material for heat dissipation is arranged in the internal space 24 of the housing 14, the board 12 does not exist in the housing 14 before the male connector 16 is assembled. Etc. are less likely to occur. In this case, the potting material or gel material may be positioned so as not to flow toward the male connector 16 before being cured, and the male connector 16 is assembled to the housing 14 and then cured.

  Moreover, since the board | substrate 12 is assembled | attached with respect to the male connector 16, the positional accuracy of the contact part 48 of the terminal 34 and the land 20 can be improved. Even when a potting material or gel material for heat radiation is arranged in the internal space 24, the terminal 34 and the land 20 are electrically connected before curing. Can be improved.

  Moreover, in this embodiment, since the board | substrate 12 is assembled | attached to the male connector 16 side, the board | substrate 12 is not displaced with the relative displacement of the housing | casing 14 and the male connector 16. FIG. For this reason, wiping of the surface of the land 20 is caused by the amount of displacement of the contact portion 48 due to the spring deformation of the terminal 34 by pushing down the opening / closing plate 36. Therefore, the wiping distance of the land 20 by the contact portion 48 can be shortened. Thereby, the physique of the land 20 and by extension, the board | substrate 12 can be reduced in size.

  In addition, although the example which provides the board | substrate holding | maintenance part 84 in the X direction both ends in the cylinder part 40 of the housing 32 was shown, the arrangement | positioning is not limited to the said example. For example, the substrate holding portion 84 can be provided near the center of the housing 32 in the X direction.

  The configuration shown in the present embodiment can be combined with any of the first to fourth embodiments.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  In the embodiment described above, in order to prevent the opening / closing plate 36 from falling off the housing 32, the opening / closing plate 36 is provided with a wedge-shaped retaining protrusion 66, and the retaining recess 68 is provided on the wall surface of the plate insertion hole 52 of the cylindrical portion 40. An example of providing is shown. However, the retaining structure of the opening / closing plate 36 is not limited to the above example. For example, as shown in the first modified example of FIG. 24, a retaining portion 94 may be provided on the outer surface of the tubular portion 40 of the housing 32 to hold the opening / closing plate 36.

  In FIG. 24, the opening / closing plate 36 has a guide projection 80. The guide projections 80 are provided at both ends in the X direction with respect to the opening / closing plate 36 shown in the first embodiment. Further, the male connector 16 is provided so as not to hit the housing 14 when the male connector 16 is inserted. The retaining portion 94 has a substantially L shape that can be elastically deformed in the X direction. The retaining portion 94 extends in the Z direction from the vicinity of the guide groove 82 on the outer surface of the cylindrical portion 40, and extends toward the plate insertion hole 52 in the X direction. It is bent. In this configuration, the opening / closing plate 36 is inserted into the plate insertion hole 52 in a state where the retaining portion 94 is bent outward in the X direction. The guide protrusion 80 of the opening / closing plate 36 held by the reaction force due to the spring deformation of the terminal 34 is pressed by the retaining portion 94. According to this, the open / close plate 36 can be pulled out from the housing 32 by bending the retaining portion 94 outward in the X direction.

  In the above embodiment, an example in which the opening / closing plate 36 is provided with the tapered portion 64 has been described. However, as the male connector 16 is inserted into the housing 14, the housing 14 may be provided with a tapered portion in order to push down the opening / closing plate 36.

  In the above embodiment, an example of the waterproof electronic control device 10 is shown, but a non-waterproof electronic control device 10 may be used.

  In the above-described embodiment, an example in which the housing 32 includes the receiving portion 62 has been described. However, a configuration without the receiving portion 62 may be employed.

  In the above-described embodiment, in the configuration in which the substrate 12 is assembled to the housing 14 in advance, the example in which the substrate 12 is held by the substrate pressing portions 28 and 30 of the housing 14 is shown. However, the configuration in which the substrate 12 is held is limited to the above example. Is not to be done.

  The number of the terminals 34, the logarithmic arrangement on the housing 32, and the arrangement of the lands 20 are not limited to the above example.

  In the above embodiment, an example in which the housing 32 has the plate insertion hole 52 has been described. However, the opening / closing plate 36 may be attached to the housing 32 so as to be slidable in the Z direction. Therefore, the housing 32 may be configured to include a guide for slidably holding the opening / closing plate 36 at the end on the housing 14 side.

  In the said embodiment, although the example of the opening / closing plate 36 attached to the housing 32 so that a slide was possible was shown as an opening / closing member, an opening / closing member is not limited to the said example. The opening / closing member is operably attached to the housing 32 in order to press the board connecting portion 44 at a position different from the contact portion 48. Further, as part of the male connector 16 is inserted into the internal space 24 from the opening 22, the male connector 16 is pushed and actuated by the housing 14, and the contact 48 is displaced from the open position to the closed position by this action. Anything can be used. For example, a configuration in which the opening / closing member has an egg shape like a cam that opens and closes a valve of each cylinder in a vehicle, and the rotation shaft is an X-axis direction and is rotatably attached to the housing 32 may be employed. According to this, with the insertion of the male connector 16 into the housing 14, the opening / closing member can be rotated around the X axis. For example, the contact portion 48 can be set to the closed position at a position having a long diameter and a position far from the rotation axis.
