And an electrical device comprising: Here, lead terminals are inserted into the through holes of the substrate. In the electric device, the lead terminal unit is screwed to the substrate.

JP 2012-129017 A

  However, in the above case, before the lead terminal unit and the board are screwed together, the lead terminal unit and the board can be freely relatively displaced. For this reason, for example, when the positions of the lead terminal and the through hole formed in the substrate do not match, the lead terminal may be bent when the lead terminal is inserted into the through hole. In addition, for example, the position of the lead terminal with respect to the through hole is not determined before the lead terminal unit and the substrate are screwed together, and it is difficult to solder the lead terminal. Furthermore, for example, it becomes difficult to assemble the substrate to other members in the electric device after inserting the lead terminal into the through hole.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an electrical device in which a plurality of lead terminals can be easily inserted into a through hole of a board so that the lead terminal unit can be temporarily fixed to the board. There is to do.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
1. The electrical device is an electrical device in which a lead terminal unit including a plurality of lead terminals and an array member for arranging and fixing the plurality of lead terminals is attached to a substrate, wherein the array member includes a first protrusion and A plurality of through holes into which each of the plurality of lead terminals is inserted, and the plurality of through holes are formed in the substrate. With each of the plurality of lead terminals inserted therein, the second projecting portion comes into contact with the substrate while exerting an elastic force, and the first projecting portion and the second projecting portion contact each other of the substrate. It is characterized by holding the part.

  In the above configuration, when the transition is made from the state in which a part of the substrate is not sandwiched between the first projection and the second projection to the sandwiched state, the second projection is easily elastically deformed. The second protrusion is elastically deformed to come into contact with the substrate. When a part of the substrate is sandwiched between the first protrusion and the second protrusion, the second protrusion is in contact with the substrate while exerting an elastic force. For this reason, a part of the substrate and the lead terminal unit can be coupled by the force that the elastic force exerts on the substrate toward the first protrusion and the reaction of the force that the first protrusion exerts from the substrate. .

  In addition, since the first protrusion is less easily elastically deformed than the second protrusion, compared to the case where the first protrusion is easily elastically deformed in the same manner as the second protrusion, the first protrusion is the first to be held. By bringing the first protrusions into contact with the substrate, the relative displacement between the first protrusions and the substrate can be easily regulated. For this reason, a board | substrate and a lead terminal unit can be positioned. Then, when the lead terminal is inserted into the through hole by shifting from the non-clamped state to the clamped state, a situation in which the lead terminal is bent due to the positional deviation between the through hole and the lead terminal is suppressed. Can do. Therefore, the lead terminal unit can be temporarily fixed to the control board by easily inserting a plurality of lead terminals into the through holes of the board.

  2. In the electric device according to the above item 1, the plurality of through holes are arranged in a line along a first end surface of four end surfaces defining four sides of the substrate, and the first end surface includes the first end surface. The two end faces connected to the first end face have first notches recessed from the first end face toward the second end face facing the first end face at both ends in the longitudinal direction of the end face. Each of the third end surface and the fourth end surface has a second cutout portion in which the third end surface and the fourth end surface are recessed toward the end surfaces facing each other, and the first protrusion portion is formed in the longitudinal direction. A pair of first cutout portions formed on both end portions are provided so as to contact the substrate, and the second protrusions are formed on the third end surface and the fourth end surface, respectively. Further, each of the second cutout portions is in contact with the substrate. The first protrusion and the second protrusion adjacent to each other in the facing direction in which the first end face and the second end face face each other are adjacent to each other in the facing direction of the substrate. A portion between one notch and the second notch is sandwiched.

  In the above configuration, the first protrusion is in contact with the first end surface on the second end surface side. For this reason, the lead terminal can be positioned in the facing direction in which the first end surface and the second end surface are opposed to each other in the four directions by the step of bringing the pair of protrusions into contact with the substrate.

3. 3. The electric device according to 2 above, wherein the first protrusion sandwiches a portion of the substrate between the pair of first notches.
In the said structure, the both sides of the longitudinal direction both ends of the 1st end surface are contacting the 1st projection part. For this reason, the lead terminal can be positioned in the longitudinal direction of the first end face in the four directions by the step of sandwiching the substrate between the first protrusions.

  4). In the electric device according to 2 or 3, the length between the first protrusion and the lead terminal in the opposing direction of the first end surface and the second end surface is the second protrusion and the second terminal. It is shorter than the length between the lead terminals.

  In the above configuration, the first protrusions are arranged so as to sandwich both ends of the first end surface in the longitudinal direction, and the lead terminals are arranged in a line along the first end surface. For this reason, by shortening the length between the first protrusion and the lead terminal in the facing direction, the lead terminal is connected to the first terminal compared to the case where the length between the second protrusion and the lead terminal is shorter. It can be close to the end face. And considering that it is difficult to mount the component between the lead terminal and the first end surface, the component of the control board is reduced by shortening the length between the first protrusion and the lead terminal in the facing direction. The mounting area can be easily expanded.

  5. 5. The electric device according to any one of 2 to 4, wherein the arrangement member is disposed adjacent to the first protrusion and has a short protrusion with a smaller protrusion than the first protrusion, and A third protrusion disposed on a side opposite to the first protrusion with respect to the second protrusion, and the top surfaces of the short protrusion and the third protrusion define the front and back of the substrate. Of the pair of main surfaces, the main surface on the base side of the lead terminal inserted into the through hole is in contact.

  In the above configuration, the main surface and the lead terminal unit in the direction orthogonal to the main surface are positioned by the short protrusion and the third protrusion that are separated from each other in the direction in which the first end surface and the second end surface face each other. In particular, the angle between the lead terminal and the main surface can be adjusted by adjusting the protruding amounts of the short protruding portion and the third protruding portion.

  6). 5. The electric device according to 5, wherein the board is a control board on which a motor control device is mounted, the control board is assembled to a member in a motor unit including the motor, and the lead terminal is A sensor substrate having a first pin portion inserted into the through-hole on the control board, which is the through hole, and a second pin portion extending in parallel with the main surface, on which a sensor for detecting the rotation angle of the motor is mounted The sensor board is formed with a sensor board side through hole into which the second pin portion of each of the plurality of lead terminals is inserted, and the sensor board is formed in the sensor board side through hole. In a state where the second pin portion is inserted, it is assembled to a member in the motor unit, and the control board is arranged in parallel to the axial direction of the motor. The sensor substrate is disposed perpendicular to the axial direction of the motor.

  In the above configuration, by arranging the sensor substrate in the axial direction of the motor, the rotation of the rotation shaft of the motor can be easily detected by the sensor mounted on the sensor substrate. Since the control board is arranged parallel to the axial direction separately from the sensor board, the main surface of the sensor board and the main surface of the control board are orthogonal to each other. The diameter of the motor unit can be reduced as compared with the case where the substrate is disposed orthogonal to the axial direction.

  In addition, the mounting components of the sensor board and the control board can be electrically connected to each other via a lead terminal including the first pin portion and the second pin portion.

As shown in FIG. 2, the lead terminal 42 includes a plurality of lead terminals 42 including a first pin portion 42 a and a second pin portion 42 b, and an arrangement member 44 that arranges and fixes the plurality of lead terminals 42. ing. Here, the array member 44 is made of resin. On the other hand, the first pin portion 42a and the second pin portion 42b of the lead terminal 42 are integrally formed, and are conductors in a conductive state. As shown in FIG. 2, the second pin portions 42b are arranged at equal intervals. Further, the second pin portions 42b have the same amount of protrusion from the arrangement member 44.

  FIG. 3 is a front view of the lead terminal unit 40 in FIG. 2 viewed from the direction parallel to the direction in which the second pin portion 42b extends and opposite to the tip side of the second pin portion 42b. As illustrated, the plurality of first pin portions 42 a have the same amount of protrusion from the array member 44. Moreover, the 1st pin part 42a is arrange | positioned at equal intervals.

  4 shows a cross-sectional view taken along the line 4-4 of FIG. As shown in FIG. 4, the lead terminal 42 is formed by bending a single rod-shaped conductor so that the extending direction of the first pin portion 42a and the extending direction of the second pin portion 42b are orthogonal to each other. . On the other hand, the array member 44 includes a first protrusion 45 adjacent to the first pin portion 42a. The first protrusion 45 protrudes from a part of the arrangement member 44 and protrudes in a direction parallel to the protrusion direction of the first pin portion 42a. The array member 44 includes a second protrusion 46 protruding in a direction parallel to the protruding direction of the first pin portion 42a. The second protrusion 46 is a part of the arrangement member 44 protruding. The second protrusion 46 is made of resin and is a part of the U-shaped member that is extended longer than the other, and the portion that is not extended is connected to the main body of the array member 44. It is a root portion 46a. The second protrusion 46 has only a base part 46 a that is one end of the U-shape connected to the main body of the array member 44, and the entire U-shaped member is thinner than the first protrusion 45. The elastic deformation is easier than that of the first protrusion 45. The array member 44 includes a third protrusion 47 that protrudes in a direction parallel to the protrusion direction of the first pin portion 42a. The third protrusion 47 is a part of the arrangement member 44 protruding.

  The first protrusion 45 is connected to a short protrusion 48 having a smaller protrusion than the first protrusion 45. Both the top surface 48a of the short projecting portion 48 and the top surface 47a of the third projecting portion 47 are orthogonal to the protruding direction of the first pin portion 42a. Further, the top surface 48a of the short protrusion 48 and the top surface 47a of the third protrusion 47 are included in the same plane.

FIG. 5 shows a 5-5 cross section of FIG.
FIG. 6 shows a state where the lead terminal unit 40 is temporarily fixed to the control board 20. As shown in FIG. 6, the lead terminal unit 40 includes a first end surface 21, a second end surface 22, a third end surface 23, and a fourth end surface 24 that are four end surfaces that define four sides of the control board 20. It is assembled on the one end face 21 side. Here, the first end surface 21, the second end surface 22, the third end surface 23, and the fourth end surface 24 have four rectangular sides when the substantially rectangular main surface 20 a of the control board 20 is regarded as a complete rectangle. It is along. That is, the first end surface 21 and the second end surface 22 are along the pair of rectangular short sides, and the third end surface 23 and the fourth end surface 24 are along the pair of long sides of the rectangle. Is.

  In FIG. 6, the long side direction DL when the main surface 20a is regarded as a complete rectangle is described as the first direction D1 and the second direction, and the short side direction DS is set as the third direction D3 and the fourth direction D4. It is described.

  On the first end surface 21 side of the control substrate 20, control substrate side through holes SHa are arranged in a line along the longitudinal direction of the first end surface 21 (the short side direction DS of the main surface 20a). In other words, when the main surface 20a is regarded as a complete rectangle, the control board side through holes SHa are arranged in parallel with one short side of the rectangle. The first pin portion 42a of the lead terminal unit 40 is inserted into the control board side through hole SHa. Accordingly, the first pin portion 42a is disposed so as to extend in a direction orthogonal to the main surface 20a of the control board 20, and the second pin portion 42b is disposed so as to extend in a direction parallel to the main surface 20a. The

  First notches 21c that are recessed from the first end surface 21 toward the second end surface 22 are formed at both ends in the longitudinal direction of the first end surface 21 (the short side direction DS of the main surface 20a). The first notch 21c includes a first positioning surface 21a parallel to the long side direction DL and a second positioning surface 21b parallel to the short side direction DS. The first protrusion 45 is in contact with the control board 20 at the first notch 21c. Specifically, in each of the first notches 21c at both ends in the longitudinal direction of the first end surface 21, the first protrusion 45 comes into contact with the first positioning surface 21a, so that the pair of first protrusions 45 The control board 20 is sandwiched from both sides of the first end face 21 in the longitudinal direction.

  In each of the first notches 21c, the first protrusion 45 is also in contact with the second positioning surface 21b. On the other hand, the control board 20 includes a second notch portion 23 b that is recessed toward the end surfaces facing each other on the third end surface 23 and the fourth end surface 24 connected to the first end surface 21. And the 2nd projection part 46 is contacting the elastic contact part 23a of the 2nd notch part 23b, exerting an elastic force, and is engaged by snap fit. Therefore, the control substrate 20 is opposed by the first protrusion 45 and the second protrusion 46 that are adjacent to each other in the facing direction in which the first end surface 21 and the second end surface 22 face each other (long side direction DL of the main surface 20a). A portion between the first cutout portion 21c and the second cutout portion 23b adjacent in the direction is sandwiched. That is, the first projecting portion 45 and the second projecting portion 46 are coupled to the control substrate 20 by exerting a reaction and reaction force with each other in the facing direction.

  The top surface 48 a of the short protrusion 48 connected to the first protrusion 45 is in contact with the main surface 20 b on the base side of the first pin portion 42 a in the control board 20. Further, in the third protrusion 47, the top surface 47a shown in FIG. 5 is in contact with the main surface 20b.

Here, the operation of the present embodiment will be described.
When temporarily attaching the lead terminal unit 40 to the control board 20, hold the control board 20 in one hand, hold the lead terminal unit 40 in the other hand, and attach the first protrusion 45 to the first notch 21c. Make contact. Thereby, the lead terminal unit 40 is positioned in the long side direction DL and the short side direction DS. Therefore, at this time, each of the first pin portions 42a is disposed at a position corresponding to each of the control board side through holes SHa of the control board 20.

  Next, the second protrusion 46 is engaged with the elastic contact portion 23a. Here, the second protrusion 46 is a member that is more easily elastically deformed than the first protrusion 45. For this reason, the 2nd projection part 46 is elastically deformed by being pressed down to the elastic contact part 23a side, and changes temporarily into a suitable shape to engage with the elastic contact part 23a. And after engaging with the elastic contact part 23a, the 2nd projection part 46 contacts the control board 20 in the side (1st direction D1 side) which opposes the 1st end surface 21. FIG. Moreover, the second protrusion 46 comes into contact with the control board 20 while exerting a force on the first direction D1 side. This force is due to the elastic deformation of the second protrusion 46. Accordingly, a part of the control board 20 is sandwiched between the first protrusion 45 and the second protrusion 46, and the lead terminal unit 40 is temporarily fixed to the control board 20.

  When the lead terminal unit 40 is temporarily fixed to the control board 20, each of the first pin portions 42a is soldered to the corresponding control board side through hole SHa. That is, the control board side through hole SHa includes a land that surrounds the hole into which the first pin portion 42a is inserted and is a conductor formed on the control board 20, and the first pin portion 42a is provided in the land. Solder.

  Next, as shown in FIG. 7, the control board 20 to which the lead terminal unit 40 is temporarily fastened is assembled to the heat sink 60 with bolts 50. Incidentally, in FIG. 7, the insertion hole 62 is for inserting the rotating shaft of the motor 12.

  When the control board 20 is assembled to the heat sink 60, the sensor board 30 shown in FIG. 1 is then assembled to the heat sink 60 with the surface on which the rotation angle sensor is mounted facing the heat sink 60. At this time, the second pin portion 42b is inserted into the sensor substrate side through hole SHb of the sensor substrate 30 using a positioning pin or the like. Then, the second pin portion 42b is soldered to the sensor substrate side through hole SHb.

According to the present embodiment described above, the following effects can be obtained.
(1) The second protrusion 46 is more easily elastically deformed than the first protrusion 45, and the second protrusion 46 is brought into contact with the elastic contact portion 23a so that the first protrusion 45 and the second protrusion 46 are connected to the control board. A part of 20 was sandwiched. Thereby, the plurality of first pin portions 42 a of the lead terminal unit 40 can be temporarily fixed in a state where the first pin portions 42 a are inserted into the control board side through holes SHa of the control board 20.

  Moreover, the first protrusion 45 is less easily elastically deformed than the second protrusion 46. For this reason, as compared with the case where the elastic deformation is facilitated similarly to the second protrusion 46, the first protrusion 45 is brought into contact with the control board 20 when the first pin part 42a is inserted into the control board side through hole SHa. This makes it easy to regulate the relative displacement between the control board 20 and the lead terminal unit 40. For this reason, the control board 20 and the lead terminal unit 40 can be positioned. Therefore, the lead terminal unit 40 can be temporarily fixed to the control board 20 by easily inserting a plurality of lead terminals (first pin portions 42a) into the control board side through hole SHa of the control board 20.

  (2) The first protrusion 45 is brought into contact with the first end surface 21 on the side facing the second end surface 22. Thereby, relative positioning of the control board 20 and the lead terminal unit 40 can be performed in the long side direction DL.

  (3) A pair of first protrusions 45 are brought into contact with the first positioning surface 21 a of the first notch 21 c of the control board 20, and the control board 20 is moved in the longitudinal direction of the first end face 21 by the first protrusion 45. It was clamped from both sides (short side direction DS of the main surface 20a). Thereby, relative positioning of the lead terminal unit 40 and the control board 20 can be performed in the short side direction DS.

  (4) In the facing direction in which the first end surface 21 and the second end surface 22 face each other (the long side direction DL of the main surface 20a), the length between the first protrusion 45 and the first pin 42a is 2 The length was shorter than the length between the protrusion 46 and the first pin portion 42a. Thus, by shortening the length between the first protrusion 45 and the first pin 42a in the long side direction DL, the length between the second protrusion 46 and the first pin 42a is reduced. The first pin portion 42a can be brought closer to the first end face 21 as compared with the case where the length is shorter. Then, considering that it is difficult to mount a component between the first pin portion 42a and the first end surface 21, the length between the first protrusion 45 and the first pin portion 42a in the long side direction DL is set to be long. By shortening, the area which mounts components among the control boards 20 can be expanded easily.

  (5) The short protrusion part 48 and the 3rd protrusion part 47 were provided, and those top surfaces 47a and 48a were made to contact the main surface 20b. Thereby, by adjusting the protrusion amount of the short protrusion part 48 and the 3rd protrusion part 47, the angle which the main surface 20b and the protrusion direction of the 1st pin part 42a make can be adjusted.

  (6) The board mounted on the motor unit 10 is divided into the control board 20 and the sensor board 30 so that the sensor board 30 is orthogonal to the axial direction Da and the control board 20 is arranged in parallel to the axial direction Da. 20 and the sensor substrate 30 were electrically connected by the lead terminal unit 40. Here, by disposing the sensor substrate 30 in the axial direction Da of the motor 12, the rotation of the rotation shaft of the motor 12 can be easily detected by the sensor mounted on the sensor substrate 30. Then, by disposing the control board 20 in parallel with the axial direction Da separately from the sensor board 30, the main surface of the sensor board 30 and the main surface of the control board 20 are orthogonal to each other. As compared with the case where the control board 20 and the control board 20 are arranged perpendicular to the axial direction Da as a single board, the diameter of the motor unit 10 can be reduced.

  In addition, the mounting components of the sensor substrate 30 and the control substrate 20 can be electrically connected to each other via the lead terminal 42 including the first pin portion 42a and the second pin portion 42b.

<Other embodiments>
In addition, you may change at least 1 of each matter of the said embodiment as follows. In the following, there is a portion that illustrates the correspondence relationship between the items described in the column of “Means for Solving the Problem” and the items in the above embodiment by reference numerals, etc. There is no intention to limit. Note that “substrate” described in “1” to “3”, “5” in the column of “means for solving the problem” corresponds to the control substrate 20.

・ "About the control board (20)"
It is not essential to form the first positioning surface 21 a on the first end surface 21. Even if the first positioning surface 21a is not formed, the lead terminal unit 40 can be positioned in the long side direction DL by the first protrusion 45 coming into contact with the second positioning surface 21b.

  It is not essential to provide the first end surface 21 with a positioning surface that contacts the first protrusion 45. For example, the width of the second cutout portion 23b in the long side direction DL may be increased so that the first protrusion 45 can be easily inserted, and the second cutout portion 23b may be used as a positioning surface. In this case, when the second protrusion 46 comes into contact with the first end surface 21 while exerting an elastic force in the second direction D2, a part of the control board 20 is caused by the first protrusion 45 and the second protrusion 46. It will be sandwiched and temporarily fixed. Incidentally, in this case, in the long side direction DL, the length between the first pin portion 42a and the second projection portion 46 is controlled to be shorter than the length between the first pin portion 42a and the first projection portion 45. This is effective in increasing the mounting area of the substrate 20.

・ "About 2nd notch part (23b) and elastic contact part (23a)"
The fact that the first end surface 21 may be used as the elastic contact portion, not limited to the elastic contact portion 23a formed on the third end surface 23 and the fourth end surface 24, is described in “Control Board (20)”. As another example in which the first end face 21 is an elastic contact portion, as shown in FIG. 6, the first end face 21 in which the first protrusion 45 is brought into contact with both end portions of the first end face 21. An elastic contact portion may be formed at the center of the second protrusion and the second protrusion may be fitted. Further, for example, a hole penetrating the control board 20 perpendicular to the main surface (the first main surface 20a and the second main surface 20b) of the control board 20 is formed, and the inner peripheral surface defining the hole is defined as an elastic contact portion. It is good. This is an embodiment that does not include the second notch.

It is not limited to one extended part of the U-shape. For example, a long bar portion of an uppercase L letter may be used. In this case, the short bar portion is connected to the main body of the array member 44.

  Moreover, it is not essential that the second protrusion is formed integrally with the main body of the arrangement member. For example, it may be formed of a metal that is easily elastically deformed and assembled to the main body of the array member.

・ "About the 3rd protrusion (47)"
Even if the third protrusion 47 is not provided, the effects (1) and the like can be obtained.
・ "Lead terminal unit (40)"
It is not essential to provide the second pin portion 42b. When this is not provided, for example, a lead terminal unit is also assembled to the sensor board 30 and the lead terminal unit of the control board 20 and the lead terminal unit of the sensor board 30 are electrically connected by a connector having a female terminal. do it.

・ "Assembly method"
In the above embodiment, the lead terminal unit 40 is assembled to the control board 20 by hand.

  In the above embodiment, after the first pin portion 42a is inserted into the control board side through hole SHa and soldered, the control board 20 and the lead terminal unit 40 are replaced with the members (heat sink 60) in the motor unit including the motor 12. However, it is not limited to this. For example, the first pin portion 42a may be soldered after the control board 20 and the lead terminal unit 40 are assembled to the heat sink 60.
