Description

[Technical Field]

[0001] The present disclosure relates to electronic devices. [Background technology]

[0002] An example of an electronic device is a rotating electrical machine in which a circuit board and a connector are connected by press-fit terminals, and the connector is provided with press-fit terminals and positioning protrusions. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2023 / 7599 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the electronic device may have a configuration in which the connector terminals mounted on the wiring board are exposed to the outside of the housing. In this configuration, the positioning protrusions described in the prior art documents may be provided on the housing. Therefore, the provision of the positioning protrusions may increase the size of the housing.

[0005] One disclosed object is to provide an electronic device in which the wiring board and the housing are positioned while preventing the size from increasing. [Means for solving the problem]

[0006] The electronic device disclosed herein comprises: a wiring board (11) on which electronic components (14) are mounted; At least one first connector terminal (20) mounted on the wiring board; At least one second connector terminal (30) that is longer than the first connector terminal and is mounted on the wiring board; a housing (40c) for accommodating a wiring board; The housing is The connector has a first insertion hole (43c) into which the first connector terminal is inserted and a second insertion hole (46c) into which the second connector terminal is inserted, The second insertion hole is provided with an inclined portion (47c) whose opening area increases as it approaches the wiring board.

[0007] In this way, the electronic device has the second connector terminals that are longer than the first connector terminals. Therefore, when assembling the wiring board and the housing of the electronic device, the second connector terminals are inserted into the second insertion holes before the first connector terminals are inserted into the first insertion holes. Therefore, the wiring board and the housing of the electronic device are positioned by the second connector terminals and the second insertion holes.

[0008] Furthermore, the electronic device is positioned using the second connector terminals mounted on the wiring board, so the housing does not need to include positioning protrusions, which prevents the electronic device from becoming too large.

[0009] Furthermore, even if the second connector terminals are not properly positioned relative to the second insertion holes, they can be inserted into the second insertion holes along the inclined portions, which reduces the load on the second connector terminals and the wiring board when the electronic device is assembled.

[0010] The electronic device disclosed herein comprises: a wiring board (11) on which electronic components (14) are mounted; a plurality of connector terminals (20, 30) mounted on a wiring board; At least one first connector terminal (20) mounted on the wiring board; At least one second connector terminal (30) having the same length as the first connector terminal and mounted on the wiring board; a housing (40a, 40b, 40d) for accommodating a wiring board; The housing is First insertion holes (43a, 43b, 43d) into which the first connector terminals are inserted, and second insertion holes (46a, 46b, 46d) into which the second connector terminals are inserted, a second insertion hole is provided, and a protrusion (48a, 48b, 48d) protruding toward the wiring board; The protruding portion is provided with inclined portions (47a, 47b, 47d) in which the opening area of ​​the second insertion hole becomes wider as it approaches the wiring board.

[0011] In this way, the housing has a protrusion with the second insertion hole protruding toward the wiring board. Therefore, when assembling the wiring board and the housing, the second connector terminals are inserted into the second insertion holes before the first connector terminals are inserted into the first insertion holes. Therefore, the electronic device is positioned relative to the wiring board and the housing by the second connector terminals and the second insertion holes.

[0012] Furthermore, the electronic device is positioned using the second connector terminals mounted on the wiring board, so the housing does not need to include positioning protrusions, which prevents the electronic device from becoming too large.

[0013] Furthermore, even if the second connector terminals are not properly positioned relative to the second insertion holes, they can be inserted into the second insertion holes along the inclined portions, which reduces the load on the second connector terminals and the wiring board when the electronic device is assembled.

[0014] The various aspects disclosed in this specification employ different technical means to achieve their respective objectives. The reference numerals in parentheses in the claims and in this section are intended to exemplify correspondences with the following embodiments and are not intended to limit the technical scope. The objectives, features, and advantages disclosed in this specification will become more apparent by reference to the following detailed description and the accompanying drawings.

[0016] Hereinafter, several embodiments for carrying out the present disclosure will be described with reference to the drawings. In each embodiment, parts corresponding to matters described in the preceding embodiment may be assigned the same reference numerals, and duplicated explanations may be omitted. In each embodiment, when only a part of the configuration is described, the other parts of the configuration may be applied by referring to the other embodiment described previously.

[0017] (First embodiment) An electronic control device 101 according to a first embodiment will be described with reference to Figures 1 to 5. In this embodiment, as an example, an electronic device is applied to the electronic control device 101. The electronic control device 101 includes, as components, a circuit board 10 and cases 40a and 50 for accommodating the circuit board 10.

[0018] The electronic control device 101 is configured to be mountable on, for example, a mobile object. Examples of the mobile object include vehicles such as electric cars, hybrid cars, and fuel cell cars, flying objects such as electric vertical take-off and landing aircraft and drones, ships, construction machinery, agricultural machinery, etc. However, the electronic control device 101 may also be mounted on an object other than a mobile object.

[0019] The electronic control device 101 is configured to be electrically connectable to an external device provided outside the electronic control device 101. As shown in FIG. 5, the electronic control device 101 is configured to be able to attach an external connector 200 provided on the external device for electrical connection. The external connector 200 includes a housing 201 and conductive terminals 202 held in the housing 201. The terminals 202 are female. A wire 203 is connected to one end of the terminal 202. The external connector 200 can also be called a female connector. The housing 201 can also be called a female connector housing.

[0020] The external device is, for example, another electronic control device, an actuator, a sensor device, etc. The actuator is a device to be driven by the electronic control device 101. Each of the components of the electronic control device 101 will be described below.

[0021] <Circuit board> 2, circuit board 10 includes wiring board 11, electronic component 14 mounted on wiring board 11, and a plurality of connector terminals 20, 30 mounted on wiring board 11. Circuit board 10 is disposed on a fixing base 49, which will be described later. Circuit board 10 is fixed to fixing base 49 by bolts 60. Note that circuit board 10 may also be fixed to base 40a by a fixing member other than bolts 60.

[0022] The wiring board 11 includes an electrically insulating substrate and conductive wiring provided on the insulating substrate. The wiring board 11 is a so-called printed circuit board. The wiring is provided on the surface of the insulating substrate or inside the insulating substrate. In this embodiment, as an example of the wiring board 11, a multilayer board in which wiring is stacked with an insulating substrate interposed therebetween can be used.

[0023] The wiring includes a wiring pattern formed by patterning a conductive thin film (such as copper foil) and interlayer connections formed by plating through holes, etc. Part of the wiring pattern includes electrode connections to which electrodes of electronic component 14 and connection portions 21, 31 of connector terminals 20, 30 are connected. The electrode connections are lands or pads. The wiring pattern includes electrode connections electrically isolated from electronic component 14.

[0024] The wiring board 11 has one surface S1 and an opposite surface S2 of the one surface S1. The one surface S1 and the opposite surface S2 have, for example, a rectangular shape.

[0025] The through holes are provided from one surface S1 to S2 of the wiring board 11. In other words, the through holes are provided along the thickness direction of the wiring board 11. The wiring board 11 has interlayer connections on the wall surfaces surrounding the through holes. Therefore, it can be said that the wiring board 11 has through holes 12 and 13. It can also be said that the through holes 12 and 13 include the interlayer connections. The thickness direction of the wiring board 11 is also simply referred to as the thickness direction. The thickness direction is a direction perpendicular to one surface S1 and the opposite surface S2.

[0026] The wiring board 11 is provided with a plurality of through holes 12, 13. The through holes 12, 13 are connected to electrode connection portions. The through hole 12 is connected to a connection portion 21 of an electrical connector terminal 20. The through hole 12 includes an electrode connection portion electrically connected to an electronic component 14. The through hole 13 is connected to a connection portion 31 of a positioning connector terminal 30. The through hole 13 includes an electrode connection portion electrically isolated from the electronic component 14.

[0027] The electronic component 14 has electrodes. The electrodes of the electronic component 14 are electrically connected to the electrode connection portions via conductive connection members. The electronic component 14 is mounted on the wiring board 11 with the electrodes electrically connected to the electrode connection portions. The electronic component 14 is mounted on both the one surface S1 and the opposite surface S2. However, it is sufficient that the electronic component 14 is mounted on at least one of the one surface S1 and the opposite surface S2. The conductive connection member is solder, silver paste, or the like.

[0028] At least one electronic component 14 is mounted on wiring board 11. Therefore, multiple electronic components 14 may be mounted on wiring board 11. Electronic components 14 include a microcomputer, a semiconductor switching element, a resistor element, a capacitor element, a coil, etc.

[0029] 1 and 2, the connector terminals 20, 30 include a plurality of electrical connector terminals 20 and two positioning connector terminals 30. Note that the circuit board 10 is required to have at least one positioning connector terminal 30. Therefore, the circuit board 10 may have a plurality of positioning connector terminals 30. Furthermore, the circuit board 10 may have three or more positioning connector terminals 30.

[0030] The electrical connector terminal 20 is made of a conductive material and is mainly composed of metal. The electrical connector terminal 20 includes a connection portion 21 and a terminal pin 22 extending from the connection portion 21.

[0031] Connection portion 21 is a portion that is inserted into through hole 12 and connected to through hole 12. Connection portion 21 comes into contact with through hole 12 and conducts electricity due to a restoring force generated by elastic deformation during press-fitting. Electrical connector terminal 20 is mounted on wiring board 11 with connection portion 21 inserted into through hole 12. In other words, electrical connector terminal 20 is electrically connected to electronic component 14 with electrical connector terminal 20 mounted on wiring board 11.

[0032] The terminal pin 22 is a rod-shaped portion provided in a straight line. A connection portion 21 is provided at one end of the terminal pin 22. The connection portion 21 and the terminal pin 22 are provided as a single unit. The terminal pin 22 is arranged on the one surface S1 side when the electrical connector terminal 20 is mounted on the wiring board 11. The terminal pin 22 protrudes from the one surface S1. The electrical connector terminal 20 protrudes more from the one surface S1 side than from the opposite surface S2 side. The terminal pin 22 is long enough to protrude from the base 40a, which will be described later. The symbol 23 denotes the tip of the terminal pin 22. The tip portion 23 is the end opposite the connection portion 21.

[0033] The electrical connector terminals 20 can also be considered press-fit connector terminals or press-fit terminals. Furthermore, the connection portions 21 can also be considered press-fit portions. Therefore, it can also be said that the electrical connector terminals 20 are mounted on the wiring board 11 by a press-fit structure. The electrical connector terminals 20 correspond to first connector terminals.

[0034] The electrical connector terminals 20 are terminals for electrically connecting the circuit board 10 to an external device. Therefore, the electrical connector terminals 20 can also be called external connection terminals. The electrical connector terminals 20 are connected to terminals 202 of an external connector 200. Therefore, the electrical connector terminals 20 are male.

[0035] The positioning connector terminal 30 is made of a conductive material. The positioning connector terminal 30 is mainly composed of metal. The positioning connector terminal 30 includes a connection portion 31 and a terminal pin 32 extending from the connection portion 31. Reference numeral 33 denotes the tip of the terminal pin 32. The positioning connector terminal 30 is configured similarly to the electrical connector terminal 20. The positioning connector terminal 30 is mounted on the wiring board 11 by the same mechanism as the electrical connector terminal 20. The connection portion 31 corresponds to the connection portion 21. The terminal pin 32 corresponds to the terminal pin 22. The tip portion 33 corresponds to the tip portion 23. The tip portion 33 is the end opposite to the connection portion 31.

[0036] The positioning connector terminal 30 has the same length as the electrical connector terminal 20. When both connector terminals 20, 30 are mounted on the wiring board 11, the position of the tip 33 is the same as the position of the tip 23. The position here refers to the position in the thickness direction.

[0037] The following mainly describes the differences between the positioning connector terminals 30 and the electrical connector terminals 20. For the same parts between the positioning connector terminals 30 and the electrical connector terminals 20, please refer to the description of the corresponding parts of the electrical connector terminals 20. The positioning connector terminals 30 correspond to the second connector terminals.

[0038] The positioning connector terminals 30 are mounted on the wiring board 11 with the connection portions 31 inserted into the through holes 13. In other words, even when the positioning connector terminals 30 are mounted on the wiring board 11, the positioning connector terminals 30 are electrically isolated from the electronic components 14.

[0039] The positioning connector terminals 30 are terminals for positioning the circuit board 10 and the base 40a, and can also be said to be terminals for positioning the electrical connector terminals 20 and the first insertion holes 43a into which the electrical connector terminals 20 are inserted.

[0040] 1, the wiring board 11 is mounted with aligned electrical connector terminals 20 and positioning connector terminals 30. The circuit board 10 can also be said to have a connector assembly section where a plurality of connector terminals 20, 30 are aligned and collected in a predetermined area. The positioning connector terminals 30 are provided at the very end of the connector assembly section.

[0041] The wiring board 11 has two positioning connector terminals 30 mounted diagonally around the plurality of electrical connector terminals 20. In other words, the plurality of electrical connector terminals 20 are arranged between the two positioning connector terminals 30. Since the circuit board 10 has the two positioning connector terminals 30, rotational misalignment with respect to the base 40a can be suppressed. The rotational misalignment is a misalignment in the rotational direction around an imaginary axis along the thickness direction.

[0042] <Case> Here, the cases 40a and 50 will be described with reference to Figures 1, 2, and 3. The case includes a base 40a and a cover 50. The base 40a and the cover 50 house the wiring board 11. When the base 40a and the cover 50 are assembled together, they form a housing space for housing the wiring board 11. The base 40a and the cover 50 house the electronic components 14 in addition to the wiring board 11. The base 40a corresponds to a housing.

[0043] It can also be said that the base 40a and the cover 50 house the circuit board 10 with a portion of the electrical connector terminals 20, including the tip portions 23, exposed to the external space. The external space is the space around the cases 40a and 50. Therefore, the external space and the housing space are separated by the cases 40a and 50.

[0044] The base 40a and the cover 50 are primarily made of a metal such as aluminum. However, the base 40a and the cover 50 may also be primarily made of an epoxy resin, for example. The base 40a and the cover 50 may be made of different materials. That is, for example, one of the base 40a and the cover 50 may be made of metal and the other may be made of resin.

[0045] 2, the base 40a includes a base portion 41 and an annular side wall portion 42 protruding from an end portion of the base portion 41. The base portion 41 includes an accommodation surface S11 on the accommodation space side and an outer surface S12 on the external space side. The accommodation surface S11 is the surface facing the wiring board 11. The outer surface S12 is the surface opposite the accommodation surface S11.

[0046] The side wall 42 forms the open end of the base 40a. The side wall 42 is provided in an annular shape so as to surround the storage space. A cover 50 is attached to the side wall 42. In other words, the cover 50 is attached so as to close the opening of the base 40a. The base 40a and the cover 50 are fixed together with screws or the like. However, the fixing mechanism for the base 40a and the cover 50 is not limited to screws.

[0047] 2, the base 41 is provided with a first insertion hole 43a and a second insertion hole 46a. The first insertion hole 43a is a hole into which the electrical connector terminal 20 is inserted. The first insertion hole 43a is a through-hole provided from the receiving surface S11 of the base 41 to the outer surface S12.

[0048] The second insertion hole 46a is a hole into which the positioning connector terminal 30 is inserted. The second insertion hole 46a is closed by the pocket portion 44a. The second insertion hole 46a is a hole provided from the accommodation surface S11 side of the base 41 to the outer surface S12 side. More specifically, the second insertion hole 46a is provided from the tip of the protrusion 48a (described later) to the inside of the pocket portion 44a. Therefore, the length of the second insertion hole 46a in the thickness direction is longer than the thickness of the base 41.

[0049] As shown in FIG. 1, the opening shape of the second insertion hole 46a may be the same as the cross-sectional shape of the positioning connector terminal 30. The opening shape is the shape of the second insertion hole 46a at a position parallel to one surface S1. The cross-sectional shape is the shape of a cross section parallel to one surface S1 of the positioning connector terminal 30. In this embodiment, a circular shape is used as an example of the opening shape and the cross-sectional shape. However, the opening shape and the cross-sectional shape may also be, for example, a rectangular shape.

[0050] 3, the smallest opening dimension a2 of the second insertion hole 46a may be smaller than the opening dimension a1 of the first insertion hole 43a. The opening dimensions a1 and a2 are the same as the opening area. This allows the circuit board 10 to prevent contact between the electrical connector terminals 20 and the base 40a by positioning the positioning connector terminals 30 in the second insertion hole 46a.

[0051] 1 and 2, the bag portion 44a is provided in the base portion 41. The bag portion 44a is provided so as to protrude in the thickness direction from the outer surface S12. In the present embodiment, as an example, the bag portion 44a is provided in an annular shape.

[0052] The pocket portion 44a is a portion that covers the tip portion 33 of the positioning connector terminal 30. In addition to the tip portion 33, the pocket portion 44a also covers the portion of the terminal pin 32 that is exposed from the outer surface S12. Therefore, the positioning connector terminal 30 is not exposed to the external space. In other words, a second insertion hole 46a is provided in a portion of the pocket portion 44a. It can also be said that the pocket portion 44a forms a portion of the second insertion hole 46a.

[0053] Therefore, the second insertion hole 46a is a hole with a bottom. The second insertion hole 46a is open on the storage space side and closed on the external space side by the bag portion 44a. Therefore, the electronic control device 101 can prevent foreign matter or water droplets from entering the internal space from the external space through the second insertion hole 46.

[0054] The pouch portion 44a is provided to protrude from the outer surface S12. The pouch portion 44a is provided to surround the electrical connector terminal 20. In other words, the pouch portion 44a surrounds the portion of the electrical connector terminal 20 that is exposed from the outer surface S12. It can also be said that the pouch portion 44a is provided with a portion of the second insertion hole 46a. Therefore, the base 40a has a connector insertion portion 45a formed by the annular pouch portion 44a. The connector insertion portion 45a is a recess into which the external connector 200 is inserted.

[0055] In this way, the pouch 44a also functions as a connector housing corresponding to the external connector 200. The pouch 44a can also be said to be a connector housing that surrounds at least the electrical connector 20. In other words, the base 40a is provided with an integrated connector housing. Therefore, the electronic control device 101 can suppress an increase in the volume of the base 40a compared to when the electronic control device 101 includes a connector housing that is separate from the base 40a.

[0056] The pouch 44a can also be referred to as a male connector housing. The pouch 44a can also be applied to other embodiments. The pouch 44a does not have to be annular. The pouch 44a can also be referred to as a storage section in which the positioning connector terminals 30 are arranged.

[0057] As shown in FIGS. 2 and 3, the base 41 has a protruding portion 48a on the housing surface S11. The protruding portion 48a is a portion that protrudes toward the wiring board 11 side relative to the housing surface S11. The protruding portion 48a has a second insertion hole 46a formed therein. It can also be said that the protruding portion 48a has an opening end of the second insertion hole 46a formed therein. Furthermore, a bag portion 44a is formed in an area facing the protruding portion 48a. The facing areas here are areas that face each other in the thickness direction.

[0058] The protruding portion 48a is provided with an inclined portion 47a. The inclined portion 47a is a surface that forms part of the second insertion hole 46a. The inclined portion 47a is provided from the open end of the second insertion hole 46a to the boundary between the protruding portion 48a and the base portion 41. However, the inclined portion 47a may also be provided on the base portion 41.

[0059] The opening area of ​​the second insertion hole 46a becomes larger from the external space side to the accommodation space side. In addition, it can be said that the protruding portion 48a is provided with an inclined portion 47a whereby the opening area of ​​the second insertion hole 46a becomes larger as it approaches the wiring board 11.

[0060] The positioning connector terminal 30 is inserted from the inclined portion 47a side into the pocket portion 44a side. Therefore, the inclined portion 47a can also be called a guide portion. The inclined portion 47a can also be called a tapered portion. Furthermore, the inclined portion 47a can also be called the inner peripheral surface of the protrusion 48a.

[0061] The fixing seat 49 is provided on the housing surface S11 of the base 41. That is, the fixing seat 49 is a portion that protrudes toward the wiring board 11 with respect to the housing surface S11.

[0062] <Assembly method> A method for assembling the circuit board 10 and the base 40a will be described with reference to Fig. 4. The circuit board 10 and the base 40a are assembled together by, for example, an assembly device.

[0063] First, as shown at timing t1, the circuit board 10 and the base 40a are arranged to face each other in the thickness direction. At this time, the housing surface S11 is arranged to face the circuit board 10. Then, the circuit board 10 and the base 40a are moved relatively so that they approach each other. Here, the base 40a is moved in the direction of the outline arrow.

[0064] The base 40a is provided with a protrusion 48a. Therefore, as shown at timing t2, the tip 33 of the positioning connector terminal 30 may come into contact with the inclined portion 47a before the tip 23 of the electrical connector terminal 20 reaches the base 41. In other words, if the circuit board 10 and the base 40a are misaligned, the tip 33 will come into contact with the inclined portion 47a.

[0065] The state in which the circuit board 10 and the base 40a are misaligned can also be said to be the state in which the first insertion holes 43a and the electrical connector terminals 20 are misaligned. In addition, when there is misalignment, the electrical connector terminals 20 are positioned outside the opposing area of ​​the first insertion holes 43a.

[0066] In the assembly method, when tip 33 comes into contact with inclined portion 47a, base 40a is moved in the direction of the outline arrow in that state. In this case, because positioning connector terminal 30 is in contact with inclined portion 47a, base 40a moves obliquely along inclined portion 47a as shown by the outline dashed arrow.

[0067] Naturally, if there is no misalignment, the positioning connector terminal 30 is inserted into the second insertion hole 46a without coming into contact with the inclined portion 47a. In this case, the base 40a moves in the direction of the outline arrow without moving obliquely.

[0068] Then, as shown at timing t3, the electrical connector terminals 20 are inserted into the first insertion holes 43a. That is, the electrical connector terminals 20 and the first insertion holes 43a are aligned. The circuit board 10 is assembled in a state where it is aligned with the base 40a. The electrical connector terminals 20 are easily inserted into the first insertion holes 43a so as not to come into contact with the base 41.

[0069] The circuit board 10 is fixed to the base 40a by bolts 60 with the connector terminals 20 and 30 inserted into the insertion holes 43a and 46a. Parts of the electrical connector terminals 20 protrude from the outer surface S12 when the circuit board 10 is fixed to the base 40a. A cover 50 is attached to the base 40a.

[0070] <Connector connection structure> The connection structure of the external connector 200 to the electronic control device 101 will be described using Figure 5. As described above, in the electronic control device 101, a portion of the electrical connector terminal 20 protrudes from the outer surface S12. The protruding portion of the electrical connector terminal 20 is surrounded by a pouch portion 44a. It can be said that the connector of the electronic control device 101 is formed by the protruding portion and the pouch portion 44a.

[0071] The housing 201 of the external connector 200 is inserted into the connector insertion portion 45a. The housing 201 may be fitted into the pouch portion 44a. The terminals 202 are electrically connected to the electrical connector terminals 20. In this manner, the external connector 200 is connected to the connector of the electronic control device 101.

[0072] <Effects> As described above, the base 40a has the second insertion holes 46a and the protrusions 48a that protrude toward the wiring board 11. Therefore, when assembling the wiring board 11 and the base 40a of the electronic control device 101, the positioning connector terminals 30 are inserted into the second insertion holes 46a before the electrical connector terminals 20 are inserted into the first insertion holes 43a. Therefore, in the electronic control device 101, the wiring board 11 and the base 40a are positioned by the positioning connector terminals 30 and the second insertion holes 46a. Furthermore, even if the wiring board 11 and the base 40a are misaligned before assembly, the wiring board 11 and the base 40a of the electronic control device 101 are positioned by the positioning connector terminals 30 coming into contact with the inclined portions 47a.

[0073] Furthermore, the electronic control device 101 is positioned using the positioning connector terminals 30 mounted on the wiring board 11. Therefore, the base 40a does not need to include a positioning protrusion, and the electronic control device 101 can be prevented from becoming large in size.

[0074] Furthermore, even if the positioning connector terminals 30 are not properly positioned relative to the second insertion holes 46a, they can be inserted into the second insertion holes 46a along the inclined portions 47a. Therefore, the electronic control device 101 can suppress the application of loads (weights) to the electrical connector terminals 20, the positioning connector terminals 30, and the wiring board 11 during assembly.

[0075] Furthermore, as described above, the positioning connector terminals 30 are electrically isolated from the electronic components 14. Therefore, even if a load is applied to the positioning connector terminals 30 during assembly, the electronic control device 101 can prevent the electrical performance from being impaired.

[0076] The preferred embodiments of the present disclosure have been described above. However, the present disclosure is not limited to the above embodiments, and various modifications are possible within the scope of the present disclosure. Below, second to fourth embodiments will be described as other aspects of the present disclosure. The above embodiments and the second to fourth embodiments can be implemented independently, or can be implemented in appropriate combinations. The present disclosure is not limited to the combinations shown in the embodiments, and can be implemented in various combinations.

[0077] (Second embodiment) An electronic control device 102 of the second embodiment will be described with reference to Fig. 6. Here, differences between the electronic control device 102 and the electronic control device 101 will be mainly described. The electronic control device 102 differs from the electronic control device 101 in the configuration of the base 40b. Fig. 6 is a cross-sectional view corresponding to Fig. 2.

[0078] As shown in Fig. 6, the electronic control device 102 includes a base 40b. The base 40b includes a base portion 41. The base portion 41 is provided with a first insertion hole 43b and a second insertion hole 46b. The base portion 41 is also provided with a connector housing 44b and a protrusion 48b. The first insertion hole 43b is similar to the first insertion hole 43a.

[0079] The connector housing 44b is provided so as to protrude in the thickness direction relative to the outer surface S12. The connector housing 44b is provided in an annular shape. The connector housing 44b is provided so as to surround the electrical connector terminals 20. In other words, the connector housing 44b surrounds the portions of the electrical connector terminals 20 that are exposed from the outer surface S12. Therefore, the base 40b has a connector insertion portion 45b formed in the annular connector housing 44b. The connector insertion portion 45b is a recess into which the external connector 200 is inserted.

[0080] The protruding portion 48b is provided with a second insertion hole 46b and an inclined portion 47b. The protruding portion 48b is similar to the protruding portion 48a. The inclined portion 47b is similar to the inclined portion 47a. However, the bag portion 44a is not provided in the area facing the protruding portion 48b. In other words, the second insertion hole 46b is a through hole.

[0081] In the electronic control device 102, similar to the electronic control device 101, the wiring board 11 and the base 40b are positioned by the positioning connector terminals 30 and the second insertion holes 46b. Furthermore, similar to the electronic control device 101, the electronic control device 102 can prevent the size from increasing. Furthermore, similar to the electronic control device 101, the electronic control device 102 can prevent a load (weight) from being applied to the electrical connector terminals 20, the positioning connector terminals 30, and the wiring board 11 during assembly. The method of assembling the circuit board 10 and the base 40b is the same as in the first embodiment.

[0082] (Third embodiment) An electronic control device 103 of the third embodiment will be described with reference to Fig. 7. Here, differences between the electronic control device 103 and the electronic control device 102 will be mainly described. The electronic control device 103 differs from the electronic control device 102 in the configuration of the base 40c and the positioning connector terminal 30. Fig. 7 is a cross-sectional view corresponding to Fig. 2.

[0083] 7, like the electronic control device 102, the electronic control device 103 includes an electric connector terminal 20 and a positioning connector terminal 30. The positioning connector terminal 30 of this embodiment is longer than the electric connector terminal 20. In other words, the length along the thickness direction of the positioning connector terminal 30 is longer than that of the electric connector terminal 20.

[0084] It can also be said that the lengths of the protruding portions of the electrical connector terminals 20 and the positioning connector terminals 30 are longer in the positioning connector terminals 30 than in the electrical connector terminals 20. The protruding portions are the portions of the electrical connector terminals 20 mounted on the wiring board 11 and the positioning connector terminals 30 mounted on the wiring board 11 that protrude from one surface S1.

[0085] The electronic control device 103 includes a base 40c. The base 40c includes a base portion 41. The base portion 41 is provided with a first insertion hole 43c and a second insertion hole 46c. The base portion 41 is also provided with a connector housing 44c. The base 40c includes a connector insertion portion 45c formed in the annular connector housing 44c.

[0086] However, the electronic control device 103 does not have the protrusion 48b. That is, the base 41 has a flat surface around the second insertion hole 46c. The base 41 also has an inclined portion 47c. The inclined portion 47c is a surface that forms the second insertion hole 46c.

[0087] The first insertion hole 43c is similar to the first insertion hole 43b. The connector housing 44c is similar to the connector housing 44b. The connector insertion portion 45c is similar to the connector insertion portion 45b.

[0088] As described above, the electronic control device 103 includes the positioning connector terminals 30 that are longer than the electrical connector terminals 20. Therefore, when assembling the wiring board 11 and the base 40c of the electronic control device 103, the positioning connector terminals 30 are inserted into the second insertion holes 46c before the electrical connector terminals 20 are inserted into the first insertion holes 43c. Therefore, in the electronic control device 103, the wiring board 11 and the base 40c are positioned by the positioning connector terminals 30 and the second insertion holes 46c. Furthermore, even if the wiring board 11 and the base 40c are misaligned before assembly, the positioning connector terminals 30 contact the inclined portions 47c, thereby positioning the wiring board 11 and the base 40c of the electronic control device 103. Furthermore, similar to the electronic control device 102, the electronic control device 103 can be prevented from becoming large in size.

[0089] Furthermore, even if the positioning connector terminals 30 are not properly positioned relative to the second insertion holes 46c, they can be inserted into the second insertion holes 46c along the inclined portions 47c. Therefore, the electronic control device 103 can suppress the application of load to the positioning connector terminals 30 and the wiring board 11 during assembly.

[0090] The method of assembling the circuit board 10 and the base 40c is the same as in the second embodiment. This embodiment can also be implemented in combination with other embodiments. That is, the electronic control devices 101, 102, and 104 may be provided with positioning connector terminals 30 that are longer than the electrical connector terminals 20.

[0091] (Fourth embodiment) An electronic control device 104 of the fourth embodiment will be described with reference to FIG. 8. Here, differences between the electronic control device 104 and the electronic control device 102 will be mainly described. The electronic control device 104 differs from the electronic control device 102 in the configuration of the base 40d. Note that this embodiment employs an example in which only one positioning connector terminal 30 is provided. However, the number of positioning connector terminals 30 is not particularly limited. FIG. 8 is a cross-sectional view corresponding to FIG. 2.

[0092] The electronic control device 104 includes a base 40d. The base 40d includes a base portion 41. The base portion 41 is provided with a first insertion hole 43d and a second insertion hole 46d. The base portion 41 is also provided with a connector housing 44d and an elastic member 48d. The base portion 41 is further provided with a hole in which the elastic member 48d is disposed. The first insertion hole 43b is the same as the first insertion hole 43b. The connector housing 44d is the same as the connector housing 44b.

[0093] The elastic member 48d is made of rubber, sponge, or the like. The elastic member 48d is inserted into a hole provided in the base 41. The elastic member 48d is fitted into and fixed to the base 41. However, the elastic member 48d may also be fixed to the base 41 with an adhesive.

[0094] Furthermore, the elastic member 48d is provided in an annular shape. The elastic member 48d is provided with an inclined portion 47d. The inclined portion 47d is a surface that forms the second insertion hole 46d. In other words, the inclined portion 47d is formed of the elastic member 48d. The inclined portion 47d is similar to the inclined portion 47b.

[0095] When the positioning connector terminals 30 come into contact with the metal base 41, metal chips may be generated in the base 40d. However, in the electronic control device 104, the second insertion holes 46d into which the positioning connector terminals 30 are inserted are formed of an elastic member 48d. Therefore, the electronic control device 104 can prevent contact between the positioning connector terminals 30 and the metal base 41 and the generation of metal chips that accompanies the contact.

[0096] The method of assembling the circuit board 10 and the base 40d is the same as in the second embodiment. This embodiment can also be implemented in combination with the third embodiment. That is, the electronic control device 103 may be provided with an elastic member 48d around the second insertion hole 46c. The elastic member 48d does not have to protrude from the housing surface S11.

[0097] This embodiment can also be implemented in combination with Embodiment 1. That is, in the electronic control device 101, at least the protrusion 48a may be provided with the elastic member 48d.

[0098] Although the present disclosure has been described with reference to the embodiments, it is understood that the present disclosure is not limited to the embodiments or structures. The present disclosure also encompasses various modifications and modifications within the scope of equivalents. In addition, although various combinations and forms are shown in the present disclosure, other combinations and forms including only one element, more, or less than one element are also within the scope and spirit of the present disclosure.
