The present invention relates to electrical equipment.

Conventionally, there is a motor device in which a motor and its control device are integrally provided. For example, the control device of the motor device of Patent Document 1 has a connector, a control board, and a heat sink. A plurality of fixing hooks protruding toward the control board are provided at the four corners of the connector.

JP-A-2018-207640

In the motor device of Patent Document 1, there is no configuration for positioning between the control board and the heat sink when the control board is attached to the heat sink. Therefore, in order to simplify the mounting work between the control board and the heat sink, it is conceivable to adopt the following configuration as a configuration for positioning between the control board and the heat sink. For example, a positioning hole is provided in the control board, and a pin fitted in a recess of the motor is inserted into this hole.

However, when this configuration is adopted, the control board needs to be provided with a hole for inserting a positioning pin in the control board in addition to a hole for inserting the fixing hook of the connector. In the control board, it is difficult to provide electronic components around the positioning holes. Therefore, as the number of holes provided in the control board increases, the area in which electronic components cannot be provided in the control board increases.

An object of the present invention is to provide an electric device capable of reducing the number of positioning holes provided in a substrate.

An electric device capable of achieving the above object is a substrate to be mounted on a mounting target, an electric component located on the opposite side of the board to the mounting target, and the mounting in a state of penetrating a positioning hole provided on the board. It has a positioning member for connecting the attachment target and the electric component in a state where the movement of the object and the electric component in a direction intersecting the arrangement direction thereof is restricted.

According to this configuration, the positioning member is shared as a positioning member between the electric component and the substrate and a positioning member between the substrate and the mounting target. Compared with the case where the positioning member between the electric component and the substrate and the positioning member between the substrate and the mounting target are separately provided, the number of positioning holes provided on the substrate can be reduced. As the number of positioning holes is reduced, the area in which electronic components can be provided on the substrate can be expanded. On the contrary, it is possible to reduce the size of the substrate by the amount that the number of positioning holes is reduced.

In the above electric device, the positioning member is provided integrally with the electric component, and an end portion of the positioning member on the opposite side of the electric component penetrates the substrate and is provided in a positioning recess for the mounting target. May be fitted to.

Even in this way, the positioning member is shared as a positioning member between the electric component and the substrate and a positioning member between the substrate and the mounting target.
In the above electrical equipment, the positioning member is provided integrally with the mounting target, and the end portion on the opposite side of the mounting target penetrates the substrate and is provided in the electrical component with a positioning recess. May be fitted to.

Even in this way, the positioning member is shared as a positioning member between the electric component and the substrate and a positioning member between the substrate and the mounting target.
In the above electrical equipment, at least a portion of the positioning member that fits into the recess may be provided with metal.

According to this configuration, when the positioning member is attached to or detached from the recess to be attached or the recess of the electric component, it is possible to suppress the generation of dust due to the wear of the positioning member.
In the above-mentioned electric equipment, the electric component may be a connector.

When this configuration is adopted, as an electrical device, the end of the positioning member provided integrally with the electrical component on the opposite side of the electrical component penetrates the substrate and fits into the recess to be mounted, or the mounting target. It is preferable to adopt a configuration in which the end portion on the opposite side of the positioning member provided integrally with the mounting target penetrates the substrate and fits into the recess of the electric component.

When, for example, the connector of the other party is connected to the connector, an external force acting on the substrate and the mounting target acts on the connector, and this external force is received by the mounting target via the positioning member. Therefore, it is suppressed that the substrate is pressed toward the mounting target. Since the stress generated on the substrate is relaxed, the distortion of the substrate is suppressed.

In the above electric equipment, the attachment target may be a vehicle motor.
There is a demand for miniaturization of equipment mounted on vehicles. As described above, in the above-mentioned electric equipment, the positioning member is shared as a positioning member between the electric component and the substrate and a positioning member between the substrate and the mounting target, thereby performing positioning. It is possible to reduce the number of holes. Then, it is possible to reduce the size of the substrate and, by extension, the physique of the electric device including the substrate by the amount that the number of positioning holes is reduced. Therefore, the above electrical equipment is suitable for vehicle applications.

According to the electric device of the present invention, the number of positioning holes provided on the substrate can be reduced.

The positioning pin 32 is provided on the side surface (lower surface in FIG. 1) of the connector 21 on the substrate 22 side. The positioning pin 32 has a columnar shape. The positioning pin 32 extends along the arrangement direction (vertical direction in FIG. 1) of the connector 21 and the substrate 22. A columnar fitting portion 32a is provided at the tip of the positioning pin 32. The outer diameter of the fitting portion 32a is smaller than the outer diameter of the portion of the positioning pin 32 from the connector fitting portion 31 to the fitting portion 32a.

The substrate fixing portion 33 is a portion fixed to the substrate 22, and has, for example, a columnar shape.
Various electronic components 41 are provided on the substrate 22. The electronic component 41 is fixed to the side surface of the substrate 22 opposite to the motor 11 by soldering, for example. Further, the substrate 22 has a plurality of pin insertion holes 42, 42, a first bolt insertion hole 43, and a second bolt insertion hole 44.

The same number of pin insertion holes 42 as the positioning pins 32 of the connector 21 are provided. Each pin insertion hole 42 is provided corresponding to each positioning pin 32. The inner diameter of the pin insertion hole 42 is larger than the outer diameter of the positioning pin 32. The positioning pins 32, 32 of the connector 21 are inserted into the pin insertion holes 42 from the side opposite to the motor 11.

The first bolt insertion hole 43 is provided corresponding to the substrate fixing portion 33. The inner diameter of the first bolt insertion hole 43 is smaller than the outer diameter of the board fixing portion 33 of the connector 21. A bolt 45 is inserted into the first bolt insertion hole 43 from the motor 11 side. The connector 21 is fixed to the board 22 by tightening the bolt 45 to the board fixing portion 33 of the connector 21.

The second bolt insertion hole 44 is provided at a position on the substrate 22 that is separated from the connector 21.
A plurality of fitting recesses 51 and a substrate fixing portion 52 are provided at the end of the motor 11.

The number of fitting recesses 51 is the same as the number of positioning pins 32 of the connector 21. The inner diameter of the fitting recess 51 is set to be about the same as or slightly larger than the outer diameter of the fitting portion 32a provided at the tip of the positioning pin 32. The fitting portion 32a of the positioning pin 32 penetrating the substrate 22 is fitted in the fitting recess 51.

The substrate fixing portion 52 is a portion to which the substrate 22 is fixed, and has, for example, a columnar shape. The board fixing portion 52 is provided corresponding to the second bolt insertion hole 44 of the board 22. The outer diameter of the board fixing portion 52 is larger than the inner diameter of the second bolt insertion hole 44 in the board 22. A bolt 53 is tightened to the board fixing portion 52 via a second bolt insertion hole 44 of the board 22. As a result, the substrate 22 is fixed to the motor 11.

Next, the procedure for assembling the motor device 10 will be described.
As shown in FIG. 2, when assembling the motor device 10, first, the control device 12 which is a partial assembly is assembled. That is, the positioning pin 32 of the connector 21 is inserted into the pin insertion hole 42 of the board 22 from the side opposite to the motor 11 while the connector 21 and the board 22 are brought close to each other. When the positioning pin 32 engages with the inner peripheral surface of the pin insertion hole 42, the connector 21 is positioned along the component surface, which is the surface on which the electronic component 41 of the substrate 22 is provided. Further, when viewed from the mounting direction of the connector 21 with respect to the board 22, the board fixing portion 33 of the connector 21 and the first bolt insertion hole 43 of the board 22 coincide with each other. The positioning pin 32 is inserted into the pin insertion hole 42 until the tip of the substrate fixing portion 33 comes into contact with the peripheral portion of the first bolt insertion hole 43 on the component surface of the substrate 22. After that, the bolt 45 is tightened to the board fixing portion 33 while inserting the bolt 45 into the first bolt insertion hole 43 of the board 22 from the side opposite to the connector 21. As a result, the connector 21 is fixed to the substrate 22. This completes the assembly work of the control device 12.

Next, the control device 12 which is a partial assembly is attached to the end portion of the motor 11. That is, while the substrate 22 and the motor 11 are brought close to each other, the fitting portion 32a at the tip of the positioning pin 32 penetrating the substrate 22 is fitted into the fitting recess 51 of the motor 11. As a result, the substrate 22 is positioned along the end face of the motor 11. Further, when viewed from the mounting direction of the substrate 22 with respect to the motor 11, the second bolt insertion hole 44 of the substrate 22 and the substrate fixing portion 52 of the motor 11 coincide with each other.

When the control device 12 and the motor 11 move toward each other in a direction close to each other, the step surface 32b between the portion of the positioning pin 32 from the connector fitting portion 31 to the fitting portion 32a and the fitting portion 32a is the motor 11. It is regulated by abutting on the peripheral portion of the fitting recess 51 on the end face of the. At this time, the tip of the substrate fixing portion 52 of the motor 11 comes into contact with the peripheral portion of the second bolt insertion hole 44 of the substrate 22. In this state, the bolt 53 is tightened to the board fixing portion 52 while inserting the bolt 53 into the second bolt insertion hole 44 of the board 22 from the side opposite to the motor 11. As a result, the substrate 22, and thus the control device 12, which is a partial assembly, is fixed to the end of the motor 11. This completes the assembly work of the motor device 10.

Next, the operation of the first embodiment will be described.
As in the comparative example shown in FIG. 3, depending on the product specifications and the like, positioning between the connector 21 and the substrate 22 is performed using pins 61 and 61, which are members different from the connector 21, while the substrate 22 and the substrate 22 are positioned. It is conceivable to use a pin 62, which is a member different from the connector 21, for positioning with the motor 11. However, when this configuration is adopted, it is necessary to separately provide the pin insertion holes 63 and 63 for inserting the pins 61 and 61 and the pin insertion holes 64 for inserting the pins 62. Therefore, the following concerns are concerned.

As shown in FIG. 4, in the substrate 22, the portions where the pin insertion holes 63, 63, 64, which are the positioning holes, are provided and the regions A1, A2, A3 around the pin insertion holes 63, 63, 64 have electrons. It is difficult to provide parts. Further, in the substrate 22, the portion where the first bolt insertion hole 43 and the second bolt insertion hole 44 are provided and the regions A4 and A5 around the first bolt insertion hole 43 and the second bolt insertion hole 44 are also formed. It is difficult to provide electronic components. Therefore, as the number of holes provided in the substrate 22 increases, the area in which electronic components cannot be provided in the substrate 22 increases.

In this respect, in the present embodiment, the positioning between the connector 21 and the substrate 22 and the positioning between the substrate 22 and the motor 11 are performed using the common positioning pins 32 and 32. Therefore, it is sufficient to provide the substrate 22 with pin insertion holes 42, 42 for inserting the positioning pins 32, 32. Therefore, the number of positioning holes provided in the substrate 22 is reduced as compared with the case where the positioning between the connector 21 and the substrate 22 and the positioning between the substrate 22 and the motor 11 are performed by using different pins. It is possible.

For example, in the comparative example shown in FIG. 3 above, it is possible to adopt a configuration in which the pin 62 for positioning between the substrate 22 and the motor 11 is omitted as the control device 12. Further, as the substrate 22, it is possible to adopt a configuration in which the pin insertion hole 64 into which the pin 62 is inserted is omitted. Therefore, it is possible to reduce the area where it is difficult to provide the electronic components on the substrate 22. That is, in the comparative example shown in FIG. 3, electronic components can be provided in the portion where the pin insertion hole 64 is provided and the region A3 around the pin insertion hole 64. On the contrary, instead of providing the electronic component, it is possible to eliminate the portion of the substrate 22 where the pin insertion hole 64 is provided and the region A3 around the pin insertion hole 64. The size of the substrate 22 can be reduced by the amount that the pin insertion hole 64 and the region A3 around the pin insertion hole 64 are not provided.

Therefore, according to the first embodiment, the following effects can be obtained.
(1) The positioning pin 32 is shared as a positioning pin between the connector 21 and the substrate 22 and a positioning pin between the substrate 22 and the motor 11. Compared with the case where the positioning pin between the connector 21 and the substrate 22 and the positioning pin between the substrate 22 and the motor 11 are provided separately, the number of positioning holes provided on the substrate 22 can be reduced. it can. As the number of positioning holes is reduced, the area in which the electronic components can be provided on the substrate 22 can be expanded. On the contrary, it is possible to reduce the size of the substrate 22 by reducing the number of positioning holes.

(2) In the assembled state of the motor device 10, the stepped surface 32b between the portion from the connector fitting portion 31 to the fitting portion 32a and the fitting portion 32a of the positioning pin 32 is fitted on the end surface of the motor 11. It is kept in contact with the peripheral portion of the joint recess 51. When the plug connector is fitted to the connector fitting portion 31, an external force acting on the substrate 22 and the motor 11 acts on the connector 21, and this external force is applied to the end surface of the motor 11 via the stepped surface 32b of the positioning pin 32. Is accepted by. Therefore, it is suppressed that the substrate 22 is pressed toward the motor 11 via the substrate fixing portion 33 of the connector 21. As a result, the stress generated on the substrate 22 is relaxed, so that the substrate 22 is suppressed from being distorted. Therefore, the plug connector can be mounted on the connector fitting portion 31 while maintaining the substrate 22 in a good installation state.

(3) The positioning pin 32 is integrally molded with a synthetic resin material as a part of the connector 21. Therefore, the number of parts can be reduced as compared with the case where the positioning pin 32 is provided as a member separate from the connector 21.

(4) The motor device 10 is suitable as a drive source for a vehicle. That is, there is a demand for miniaturization of equipment mounted on vehicles. As described above, in the motor device 10, the positioning pin 32 is shared as a positioning pin between the connector 21 and the substrate 22 and a positioning pin between the substrate 22 and the motor 11 for positioning. It is possible to reduce the number of holes for. Then, the size of the substrate 22 and the motor device 10 including the substrate 22 can be reduced by the amount that the number of positioning holes is reduced. Therefore, the motor device 10 is suitable for in-vehicle use.

<Second embodiment>

The positioning pin 54 is inserted into the pin insertion hole 42 of the substrate 22 from the motor 11 side. The fitting portion 54a of the positioning pin 54 is fitted into the fitting recess 35 of the connector 21 from the motor 11 side. The connector 21 is supported by the motor 11 by the positioning pin 54.

The connector fixing portion 55 is a portion to which the connector 21 is fixed, and has, for example, a columnar shape. The connector fixing portion 55 is provided corresponding to the first bolt insertion hole 43 of the substrate 22. The outer diameter of the connector fixing portion 55 is larger than the inner diameter of the first bolt insertion hole 43 in the substrate 22. The bolt 56 is tightened to the connector fixing portion 55 through the bolt insertion hole 34 of the connector 21 and the first bolt insertion hole 43 of the substrate 22. As a result, the connector 21 is fixed to the motor 11.

That is, the positioning pins 54 and 54 of the motor 11 are inserted into the pin insertion holes 42 and 42 of the substrate 22 while the substrate 22 and the motor 11 are brought close to each other. The movement of the substrate 22 and the motor 11 toward each other means that the connector fixing portion 55 of the motor 11 comes into contact with the peripheral portion of the first bolt insertion hole 43 on the side surface of the substrate 22 on the motor 11 side. The substrate fixing portion 52 of the motor 11 is regulated by abutting on the peripheral portion of the second bolt insertion hole 44 on the side surface of the substrate 22 on the motor 11 side. Further, the substrate 22 is positioned along the end surface of the motor 11 by engaging the positioning pin 54 with the inner peripheral surface of the pin insertion hole 42.

The second bolt insertion hole of the substrate 22 in a state where the substrate 22 is positioned with respect to the end face of the motor 11 by the positioning pins 54 and 54 and the substrate 22 is supported by the connector fixing portion 55 and the substrate fixing portion 52. While inserting the bolt 53 into the 44 from the side opposite to the motor 11, the bolt 53 is tightened to the substrate fixing portion 52. As a result, the substrate 22 is fixed to the end of the motor 11.

Next, while the motor 11 to which the board 22 is attached and the connector 21 are brought close to each other, the fitting portions 54a and 54a of the positioning pins 54 and 54 penetrating the board 22 are fitted into the fitting recesses 35 and 35 of the connector 21. Match. The movement of the motor 11 to which the board 22 is attached and the connector 21 in a direction close to each other is a stepped surface between the portion of the positioning pin 54 from the end surface of the motor 11 to the fitting portion 54a and the fitting portion 54a. 54b is regulated by abutting the peripheral portion of the fitting recess 35 on the side surface of the connector 21 on the motor 11 side.

By fitting the fitting portions 54a, 54a of the positioning pins 54, 54 into the fitting recesses 35, 35 of the connector 21, the connector 21 is oriented along the end surface of the motor 11, and eventually along the component surface of the substrate 22. Positioned. At this time, the bolt insertion hole 34 of the connector 21 coincides with the first bolt insertion hole 43 of the substrate 22 and the connector fixing portion 55 of the motor 11 when viewed from the mounting direction of the connector 21 with respect to the motor 11. In this state, the bolt 56 is tightened to the connector fixing portion 55 of the motor 11 while inserting the bolt 56 into the bolt insertion hole 34 of the connector 21 from the side opposite to the motor 11. As a result, the connector 21 is fixed to the end of the motor 11 while being supported by the positioning pins 54 and 54. The front end surface (lower end surface in FIGS. and 6) of the connector support portion 34a is maintained in contact with the substrate 22. This completes the assembly work of the motor device 10.
