Further, as shown in FIG. 6B, in the control circuit board 51 held by the board holding member 35, the plurality of second connection terminals 51b led out in the direction opposite to the insertion direction X are the tip portions thereof. Protrudes outside the connector housing 22 from the insertion opening 27a.

  As shown in FIG. 7A, two noise prevention elements 53 are inserted into the element housing portion 27c. Each noise prevention element 53 is inserted into the element accommodating portion 27 c so that its terminal is on the insertion opening 27 a side of the insertion recess 27. These noise prevention elements 53 are capacitors and are electronic components for erasing electrical noise.

  As shown in FIGS. 6A and 7A, a flat relay member 54 is connected to the plurality of second connection terminals 51b protruding from the insertion opening 27a to the outside of the connector housing 22. Yes. The relay member 54 is a member for achieving electrical continuity between the connector terminal 32 and the control circuit board 51. In the present embodiment, the relay member 54 is a printed board. A plurality of first through holes 54 a corresponding to the plurality of second connection terminals 51 b are formed in a portion of the relay member 54 that faces the insertion hole 36 in the insertion direction X. In addition, a plurality of second through holes 54 b into which the end portions of the plurality of connector terminals 32 protruding from the positioning surface 30 are inserted are formed at portions of the relay member 54 that face the positioning surface 30 in the insertion direction X. ing. Further, two pairs of third through holes 54c are formed in a portion of the relay member 54 that faces the element accommodating portion 27c in the insertion direction X.

  The relay member 54 is perpendicular to the control circuit board 51 held by the board holding member 35 and orthogonal to the insertion direction X (that is, the thickness direction of the relay member 54 and the insertion direction X). Are arranged in parallel). The second connection terminals 51b of the control circuit board 51 are inserted into the plurality of first through holes 54a, respectively, and the connector terminals protruding from the positioning surface 30 are inserted into the plurality of second through holes 54b. 32 end portions are respectively inserted. Furthermore, the terminals of the anti-noise element 53 are inserted into the third through holes 54c that make a pair in the relay member 54, respectively. The terminals of the second connection terminal 51b, the connector terminal 32, and the noise prevention element 53 are electrically connected to the relay member 54 by solder. Further, all the electronic components (that is, the control circuit board 51, the noise prevention element 53, etc.) mounted on the relay member 54 are disposed on the surface of the relay member 54 on the insertion direction X side. In the present embodiment, all electronic components mounted on the relay member 54 are mounted on the surface of the relay member 54 that is inside the connector housing 22. The insertion opening end surface 27b is inclined so that the distance from the connection opening end surface 26b becomes shorter as the distance from the connector connecting portion 23 increases along the direction of the axis L2 of the connector connecting portion 23. Therefore, the second connection terminal 51 b of the control circuit board 51, the terminal of the noise prevention element 53, and the connection portion between the connector terminal 32 and the relay member 54 protrude (expose) to the outside of the connector housing 22. That is, the insertion opening end face 27b is inclined with respect to the insertion direction X so as to project the connecting portion between the second connection terminal 51b and the relay member 54 from the insertion opening 27a to the outside of the connector housing 22.

  As shown in FIGS. 9 and 10, the relay member 54 is assembled to the connector housing 22 over the positioning protrusion 31 a while tilting the positioning pin 31 by elastic deformation. Of the both surfaces of the relay member 54 in the thickness direction, the bottom surface of the insertion recess 27 abuts the positioning surface 30 from the insertion direction X, while the insertion recess 27 has a surface opposite to the bottom surface. The contact surface 31b of the convex portion 31a is in contact with the insertion direction X. In this manner, the relay member 54 is sandwiched between the positioning surface 30 and the positioning pin 31, thereby positioning the relay member 54 in the insertion direction X with respect to the connector housing 22.

  Further, the restricting convex portion 34 is close to the noise preventing element 53 inserted into the element accommodating portion 27c. Therefore, when the noise preventing element 53 tries to tilt, the noise preventing element 53 is prevented from further tilting by coming into contact with the restricting convex portion 34.

  The insertion opening 27 a is closed with a lid 41. The lid body 41 has a substantially dish shape corresponding to the insertion opening 27a. The lid 41 is formed such that the connector housing 22 whose insertion opening 27 a is closed by the lid 41 has a substantially rectangular parallelepiped shape including the lid 41. Specifically, the lid body 41 is formed by a flange portion 42 having a quadrangular frame shape surrounding the insertion opening portion 27a, and a dish-like closing portion 43 provided integrally inside the flange portion 42. ing. As shown in FIG. 4, in the state where the flange portion 42 is in contact with the insertion opening end face 27b, the closing portion 43 is inserted in the insertion direction X as it moves away from the connector connecting portion 23 along the axial direction of the connector connecting portion 23. The depth of is increased. And as shown in FIG. 10, the bottom part 43a of the obstruction | occlusion part 43 has comprised square plate shape. Of the three side walls 43b to 43d of the closing portion 43 that connects the flange portion 42 and the bottom portion 43a, the central side wall 43b has a quadrangular shape and is perpendicular to the bottom portion 43a. Further, the side walls 43c and 43d on both sides of the central side wall 43b form a right triangle shape such that the width between the bottom portion 43a and the flange portion 42 becomes narrower as the distance from the side wall 43b increases. It is a boundary part. Therefore, as shown in FIG. 4, the closed portion 43 has a right triangle shape when viewed from the direction orthogonal to the insertion direction X and the axial direction of the connector connecting portion 23. Further, as shown in FIG. 10, the lid body 41 of the present embodiment is integrally formed with the connector housing 22. That is, the part adjacent to the side wall 43b in the flange part 42 is connected to one side of the insertion opening 27a opposite to the connector connecting part 23. The lid 41 is rotatable relative to the connector housing 22 while bending the connecting portion.

  As shown in FIG. 6B, such a lid body 41 is connected to the outside of the connector housing 22 from the insertion opening 27 a in the relay member 54, the second connection terminal 51 b, the connector terminal 32, and the terminals of the noise prevention element 53. The flange portion 42 is brought into contact with the insertion opening end surface 27b while the portion projecting into the closed portion 43 is accommodated inside the closing portion 43. And the flange part 42 and the insertion opening end surface 27b are joined by ultrasonic welding. The flange portion 42 and the insertion opening end face 27b are welded to prevent liquid from entering the connector housing 22 from between the lid 41 and the insertion opening end face 27b.

  Further, as shown in FIG. 5, four locking claws 39 that engage with the four locking projections 12p formed on the fixed portion 12a are formed on the outer peripheral surface of the connector housing 22. Two locking claws 39 are formed on both end surfaces of the connector housing 22 in the direction perpendicular to the insertion direction X and perpendicular to the axial direction of the connector connecting portion 23. Each locking claw 39 extends in the insertion direction X, and each locking claw 39 is formed with a locking hole 39a capable of locking the locking projection 12p.

  In the connector module 21 configured as described above, the board holding member 35 holding the control circuit board 51 is fixed from the insertion opening 12c with the connection opening 26a and the insertion opening 12c of the fixing part 12a facing each other. It is inserted into the fixing portion 12a along the insertion direction X so as to be inserted into the portion 12a. At this time, the insertion of the substrate holding member 35 into the fixed portion 12a is guided by inserting the substrate holding member 35 into the fixed portion 12a while inserting the insertion guide convex portion 12k into the insertion guide portion 37. . Further, the substrate holding member 35 is inserted between the first axial positioning projection 12m and the second axial positioning projection 12n, so that the first axial positioning projection 12m and the second axial positioning projection 12n are inserted. The insertion into the fixed portion 12a is also guided by the axial positioning projection 12n.

  When the connector module 21 is moved in the insertion direction X until the sealing member 28 provided on the connection opening end surface 26b contacts the insertion opening end surface 12d, the respective locking claws 39 are respectively formed on the locking projections 12p. Snap-fit engagement. Accordingly, the corresponding locking projections 12p are disposed in the locking holes 39a of the locking claws 39, respectively. In this way, the connector module 21 is fixed so as not to move in the direction opposite to the insertion direction X with respect to the fixed portion 12a by the engagement of the locking claw 39 and the locking projection 12p. As shown in FIG. 4, the four locking claws 39 locked to the locking projections 12 p do not protrude from the yoke 2 and the gear housing 12 in the motor thickness direction. That is, all the locking claws 39 are formed so as to be within the thickness range of the motor.

  Further, in a state where the connector module 21 is fixed to the fixing portion 12a, the seal member 28 is in close contact with the insertion opening end surface 12d. Accordingly, liquid is prevented from entering the motor from between the connection opening end face 26b and the insertion opening end face 12d.

  As shown in FIG. 2, in the state where the connector module 21 is fixed to the fixing portion 12a, the board holding member 35 holding the control circuit board 51 by the insertion guide convex portion 12k inserted into the insertion guide portion 37. Positioning in the circumferential direction (the circumferential direction of the rotating shaft 4 and in the left-right direction in FIG. 2) with respect to the fixed portion 12a is performed. Further, the substrate holding member 35 is sandwiched from both sides in the axial direction of the rotary shaft 4 by the first axial positioning projection 12m and the second axial positioning projection 12n. For this reason, the first axial positioning protrusion 12m and the second axial positioning protrusion 12n position the substrate holding member 35 in the axial direction (in the direction of the central axis L1 of the rotating shaft 4) with respect to the fixed portion 12a. . Further, as shown in FIG. 3, when the control circuit board 51 is inserted into the fixed portion 12a, the first connection terminal 51a is connected to the armature 3 so as to be able to supply power (for example, slidably contact the armature 3). The Hall IC 52 provided in the control circuit board 51 is opposed to the sensor magnet 5 in the axial direction.

  In the motor configured as described above, an external connector (not shown) for inputting / outputting electric signals and supplying power is inserted into the insertion holes 24 of the connector connecting portion 23. When power is supplied to the armature 3 through the connector terminal 32, the armature 3 (rotating shaft 4) is rotationally driven. The rotational driving force of the rotating shaft 4 is transmitted to the worm shaft 15 via the clutch 14 and is decelerated by the worm portion 15a and the worm wheel 16 and output from the output shaft 17. Then, according to the rotation direction of the output shaft 17, the window glass is lowered or raised through the window regulator connected to the output shaft 17.

  Further, when the armature 3 is driven to rotate, the sensor magnet 5 rotates together with the rotating shaft 4. A change in the magnetic field due to the rotation of the sensor magnet 5 is detected by the Hall IC 52 provided in the control circuit board 51. The Hall IC 52 outputs a rotation detection signal that is an electric signal corresponding to a change in the magnetic field due to the rotation of the sensor magnet 5. Based on the rotation detection signal, rotation information (rotation speed, rotation angle, etc.) of the armature 3 is detected, and power is supplied to the armature 3 according to the detected rotation information.

Next, the manufacturing method of the connector module 21 of this embodiment is demonstrated.
First, as shown in FIG. 11A, a connector housing forming step (supporting step) for forming the connector housing 22 is performed. In the connector housing forming step, a terminal material 61 to be a plurality of connector terminals 32 is placed in a molding die (not shown) for molding the connector housing 22. The terminal material 61 has a shape in which a plurality of connector terminals 32 embedded in the connector housing 22 are partially connected and integrated. The terminal material 61 is formed by bending a plurality of portions after punching a conductive metal plate material into a predetermined shape by press working.

  Then, the molten insulating resin material is filled into the mold in which the terminal material 61 is disposed. Since the lid 41 is integrally formed with the connector housing 22 of the present embodiment, not only the cavity for forming the connector housing 22 but also the lid connected to the connector housing 22 is included in the molding die. A cavity for forming 41 is also formed.

  And if the insulating resin material with which the shaping | molding die was filled is cooled and solidified, the connector housing 22 with which the cover body 41 was integrally formed will be formed. The connector housing 22 and the lid 41 in the mold have a positional relationship as shown in FIG. That is, the lid 41 is open 90 degrees with respect to the connector housing 22. Therefore, the bottom portion 43 a and the side walls 43 c and 43 d of the lid body 41 are parallel to the insertion direction X, and the side wall 43 b is orthogonal to the insertion direction X. Therefore, even if the cover body 41 is integrally formed with the connector housing 22, the connector housing 22 and the cover body 41 are formed by moving the forming mold in two directions opposite to the insertion direction X and the insertion direction X. Can be taken out easily. And as shown in FIG.11 (b), the connector housing 22 taken out from the shaping | molding die is supporting the said terminal material 61 by burying the terminal material 61 in the inside. In the connector housing 22, the portion 61 a connecting the connector terminals 32 to each other in the terminal material 61 overlaps the cutting through-hole 33, so that the portion 61 a is not embedded in the resin material constituting the connector housing 22. It is exposed from the through hole 33 for cutting.

  Next, a terminal cutting step of separating the terminal material 61 to form the connector terminal 32 is performed. In the terminal cutting step, a portion 61a connecting the connector terminals 32 in the terminal material 61 is cut by pressing. After placing the connector housing 22 on a die (not shown) used for press working, a punch is inserted into the cutting through-hole 33 to cut a portion 61a of the terminal material 61 connecting the connector terminals 32 to each other. . Thereby, each connector terminal 32 is isolate | separated. In the terminal cutting step, the die is inserted into the connector housing 22 from one of the connection opening 26a and the insertion opening 27a, and the punch is inserted into the connector housing 22 from the other opening. Inserted inside.

  Next, as shown in FIG. 12, a connector boot forming step for forming the connector boot 25 is performed. In the connector boot forming step, the connector housing 22 in which the lid body 41 is integrally molded is placed in a molding die for molding the connector boot 25. Then, the molten elastomer is filled into the mold. Thereafter, the elastomer in the mold is cooled and solidified, whereby the connector boot 25 is integrally formed with the connector housing 22. In the connector boot forming step, the seal member 28 is integrally formed on the connection opening end face 26b simultaneously with the formation of the connector boot 25.

  Next, a control circuit board insertion process (arrangement process) for inserting the control circuit board 51 into the connector housing 22 is performed. The control circuit board 51 is inserted into the board holding member 35 along the insertion direction X from the end on the first connection terminal 51a side until it comes into contact with the board positioning convex part 38. Accordingly, the control circuit board 51 is held by the board holding member 35 with respect to the connector housing 22.

  Next, a relay member arranging step for arranging the relay member 54 with respect to the connector housing 22 is performed. In the relay member arranging step, as shown in FIGS. 9 and 12, first, the relay member 54 is placed at a position facing the insertion opening 27a so as to be orthogonal to the insertion direction X (that is, the thickness of the relay member 54). (The direction is parallel to the insertion direction X). Note that two anti-noise elements 53 are electrically connected to the relay member 54 in advance. Then, the relay member 54 is moved in the insertion direction X until it comes into contact with the positioning surface 30. At this time, the plurality of second connection terminals 51b are respectively inserted into the plurality of first through holes 54a, and the plurality of connector terminals 32 are respectively inserted into the plurality of second through holes 54b. At the same time, the two noise prevention elements 53 are inserted into the element accommodating portion 27c. Further, the relay member 54 is sandwiched between the positioning surface 30 and the positioning pin 31 by overcoming the positioning convex portion 31 a and contacting the positioning surface 30 while elastically deforming the positioning pin 31. Thus, the relay member 54 is supported with respect to the connector housing 22.

  The relay member 54 disposed from the insertion opening 27a with respect to the connector housing 22 is perpendicular to the control circuit board 51 held by the board holding member 35 and is orthogonal to the insertion direction X (that is, the relay member). 54 thickness direction and the insertion direction X are parallel). Note that all electronic components mounted on the relay member 54 (that is, the control circuit board 51, the noise prevention element 53, and the like) are located on the bottom surface side of the insertion recess 27 with respect to the relay member 54.

  Next, a soldering process (connection process) for electrically connecting the second connection terminals 51b and connector terminals 32 of the control circuit board 51 and the relay member 54 is performed. In the soldering step, the second connection terminal 51b, the connector terminal 32, and the relay member 54 are soldered. At this time, as shown in FIG. 6B, the distance between the insertion opening end surface 27 b and the connection opening 26 a decreases as the distance from the connector connection 23 increases along the axial direction of the connector connection 23. It is inclined to become. Therefore, the second connection terminal 51b, the connector terminal 32, and the relay member 54 protrude (expose) from the insertion opening 27a to the outside of the connector housing 22. Therefore, since the part to be soldered is exposed to the outside of the connector housing 22 from the insertion opening 27a, the soldering is easy to perform because it is exposed. Thus, the second connection terminal 51b and the connector terminal 32 of the control circuit board 51 and the relay member 54 are electrically connected by solder.

  Next, a lid mounting process for closing the insertion opening 27a with the lid 41 is performed. In the lid mounting step, first, the lid 41 is rotated with respect to the connector housing 22, and the insertion opening 27 a is closed by the lid 41. And the flange part 42 and the insertion opening end surface 27b which contact | abutted mutually are joined by ultrasonic welding. As a result, the lid body 41 is liquid-tightly fixed to the connector housing 22. Thus, the connector module 21 is completed.

As described above, according to the first embodiment, the following operational effects are obtained.
(1) In the connector housing forming step, the terminal material 61 is placed in the mold and the terminal material 61 is embedded in the connector housing 22 to support the terminal material 61 with respect to the connector housing 22. Therefore, the connector terminals 32 can be supported more easily with respect to the connector housing 22 than when the plurality of connector terminals 32 separated from each other are supported with respect to the connector housing 22. Further, in the terminal cutting step, the terminal material 61 is cut from the cutting through-hole 33 using the two openings of the connection opening 26a and the insertion opening 27a, so that the terminal material is formed inside the connector housing 22. 61 can be cut. Accordingly, it is possible to suppress the connector housing 22 and the terminal material 61 from having a complicated shape, and it is possible to easily cut the portion 61a connecting the connector terminals 32 to each other in the terminal material 61. Furthermore, the electrical connection between the connector terminal 32 and the relay member 54 is easily performed because the connector terminal 32 and the relay member 54 are supported with respect to the connector housing 22. From these things, the connector module 21 can be manufactured easily.

  (2) In the relay member arranging step, the relay member 54 is supported on the connector housing 22 from the insertion opening 27a different from the connection opening 26a closed by the gear housing 12. Therefore, when the relay member 54 is arranged with respect to the connector housing 22 in the relay member arranging step, the part inserted into the gear housing 12 in the connector module 21 is not easily obstructed. Further, since the insertion opening 27a is closed by the lid body 41 after the soldering process, the electrical connection portion between the connector terminal 32 and the relay member 54 is protected. Moreover, since the cutting through-hole 33 is formed so as to communicate with the connection opening 26a and the insertion opening 27a, when the insertion opening 27a is closed by the lid 41, the cutting through-hole is cut by the lid 41. The opening on the insertion opening 27a side of the hole 33 is closed. On the other hand, the opening on the connection opening 26 a side of the cutting through hole 33 is closed by the gear housing 12 when the connector module 21 is inserted into the gear housing 12. Therefore, in the connector module 21 including the connector housing 22 having the two openings of the connection opening 26a and the insertion opening 27a, liquid can be prevented from entering the inside of the connector housing 22 from the cutting through hole 33. The Furthermore, since the insertion opening 27a and the opening on the insertion opening 27a side of the cutting through hole 33 can be simultaneously closed by the lid 41, the connector module 21 can be manufactured more easily.

  (3) In the soldering process, the electrical connection between the connector terminal 32 and the relay member 54 and the electrical connection between the control circuit board 51 and the relay member 54 can be performed at the same time. Module 21 can be manufactured. Further, the time required for the electrical connection between the connector terminal 32 and the relay member 54 and the electrical connection between the control circuit board 51 and the relay member 54 can be shortened, so that the productivity can be improved. As a result, the manufacturing cost of the connector module 21 can be further reduced.

  (4) When the insertion opening end surface 27b and the outer peripheral edge portion (that is, the flange portion 42) of the lid body 41 are welded, the insertion opening end surface 27b and the lid body 41 are joined by the welded portion between the insertion opening end surface 27b and the lid body 41 Is sealed in a liquid-tight manner. Therefore, it is possible to prevent liquid from entering the connector housing 22 from the insertion opening 27a without providing a separate sealing member between the insertion opening end face 27b and the lid 41.

The terminal holding portion 84 is formed so as to divide the internal space of the connection recess 83 into two in the insertion direction X and the direction perpendicular to the axis L2 of the connector connection portion 23 (vertical direction in FIG. 15). The connection recess 83 is provided with the terminal holding portion 84, whereby a substrate insertion portion 83c is formed on one side (lower side in FIG. 15) of the terminal holding portion 84 and the other end of the terminal holding portion 84. An element accommodating portion 83d is formed on the side (the upper side in FIG. 15).

  Further, the positioning portion 84a that is about half of the terminal holding portion 84 on the connector connecting portion 23 side is more than the terminal protruding portion 84b that is about half of the terminal holding portion 84 on the side opposite to the connector connecting portion 23. It is formed high (a large amount of protrusion toward the connection opening 83a). Furthermore, the distal end surface of the positioning portion 84 a is orthogonal to the insertion direction X, and the distal end surface of the terminal protruding portion 84 b is also orthogonal to the insertion direction X. In addition, a positioning protrusion 84c having a columnar shape is formed at the corner of the front end surface of the terminal protrusion 84b having a rectangular shape. The front end surface of the positioning convex portion 84c is orthogonal to the insertion direction X.

  A plurality (seven in this embodiment) of connector terminals 32 are embedded in the connector housing 82 by insert molding. As shown in FIGS. 16A and 16B, these connector terminals 32 are inserted into the terminal holding portion 84 in the connector housing 82 along the axis L <b> 2 direction of the connector connecting portion 23 from the inside of the insertion hole 24. After extending, it is bent at 90 ° and extends along the insertion direction X inside the terminal protrusion 84b. That is, each connector terminal 32 has an L shape in which only one portion in the longitudinal direction is bent. Further, the end of each connector terminal 32 on the connector connecting portion 23 side protrudes from the bottom surface of the insertion hole 24 into the internal space of the insertion hole 24, and the end of each connector terminal 32 on the terminal holding portion 84 side protrudes from the terminal.

  As shown in FIGS. 14 and 15, the connector housing 82 is formed with a plurality of (in this embodiment, five) cutting through holes 33 that penetrate the connector housing 22 along the insertion direction X. . Each cutting through-hole 33 penetrates through the connector housing 82 from the distal end surface of the terminal protrusion 84b to the end surface of the connector housing 82 opposite to the connection opening 83a. Therefore, the cutting through-hole 33 communicates the outside of the connector housing 82 and the inside of the connector housing 82 (that is, the inside of the connection recess 83). Each cutting through hole 33 is formed between the plurality of connector terminals 32. Furthermore, as shown in FIG. 14, an embedded recess 86 is formed in an end portion of the connector housing 82 opposite to the connection opening 83 a in a region including the openings of the plurality of cutting through holes 33. The embedded recess 86 has a groove shape extending along the direction of the axis L <b> 2 of the connector connecting portion 23. The embedded recess 86 is filled with a seal member 87 made of an elastomer and closing the through hole 33 for cutting. Therefore, the seal member 87 prevents liquid from entering the connector housing 82 from the cutting through hole 33. The seal member 87 is formed integrally with the connector housing 82 and is formed integrally with the connector boot 25. Further, four locking claws 39 are formed on the outer peripheral surface of the connector housing 82.

As shown in FIG. 16B, the thickness of the board holding member 92 is perpendicular to the insertion direction X of the board insertion portion 83c and the axis L2 of the connector connecting portion 23 (up and down direction in FIG. 16B). It is formed slightly thicker than the width. Further, an insertion guide portion 37 is formed at the center of one of the side walls 92a and 92b in the thickness direction of the substrate holding member 92 (the lower side wall in FIG. 16B). Further, a substrate positioning convex portion 38 is formed at the center of the front end surface of the other side wall 92b.

Two holding projections 92 c are formed to protrude from the base end surface of the substrate holding member 92. Of the two holding projections 92c, one holding projection 92c is formed on the base end surface of the side wall 92a, and the other holding projection 92c is formed on the base end surface of the side wall 92b. Further, each of these two holding projections 92c has a cylindrical shape.

  Further, a positioning notch 92 d is formed at the base end of the substrate holding member 92.

  As shown in FIG. 17B, the relay member 54 is formed with two protrusion insertion holes 54d in the vicinity of the first through hole 54a. The positional relationship between the plurality of first through holes 54a and the two projection insertion holes 54d is such that the plurality of second connection terminals 51b of the control circuit board 51 inserted into the board holding member 92 and the two holding projections 92c. It is formed equal to the positional relationship. In addition, the inner diameter of each protrusion insertion hole 54d is formed substantially equal to the outer diameter of the holding protrusion 92c.

  The control circuit board 51 inserted into the board holding member 92 inserts the plurality of second connection terminals 51b into the plurality of first through holes 54a of the relay member 54 and inserts the two holding protrusions 92c into the protrusions, respectively. It arrange | positions with respect to the relay member 54 in the state inserted in the hole 54d. As shown in FIG. 18, the relay member 54 is disposed so as to be perpendicular to the control circuit board 51. The plurality of second connection terminals 51b are electrically connected to the relay member 54 by solder. Further, since the base end surface of the substrate holding member 92 abuts on the relay member 54, the tilt of the control circuit board 51 with respect to the relay member 54 is suppressed by the substrate holding member 92. Also, as shown in FIGS. 17A and 17B, the two holding projections 92c are inserted into the projection insertion holes 54d, so that the control circuit in the planar direction of the relay member 54 with respect to the relay member 54 is provided. The movement of the substrate 51 is prevented.

  The terminals of the two noise prevention elements 53 are respectively inserted into the third through holes 54c and electrically connected to the relay member 54 by solder. The two noise prevention elements 53 are arranged on the same side as the side on which the control circuit board 51 is arranged, on both sides of the relay member 54 in the thickness direction of the relay member 54.

  As shown in FIG. 13, such a control circuit unit 91 is inserted in the insertion direction so that the relay member 54 is on the bottom side of the connection recess 83 and the control circuit board 51 and the noise prevention element 53 are on the connection opening 83a side. It is inserted into the connection recess 83 along a direction parallel to X. The relay member 54 is positioned in the insertion direction X with respect to the connector housing 82 by coming into contact with the positioning projection 84c (see FIG. 15) from a direction parallel to the insertion direction X. Further, the connector terminals 32 protruding from the terminal protruding portions 84b (see FIG. 15) are inserted into the respective second through holes 54b. The connector terminals 32 inserted into the second through holes 54b are electrically connected to the relay member 54 by solder.

  The base end portion of the substrate holding member 92 that holds the control circuit substrate 51 is inserted into the substrate insertion portion 83c. Therefore, the board holding member 92 is moved by the inner peripheral surface of the board insertion portion 83c in the direction of the connector connection portion 23 in the direction of the axis L2 and the insertion direction X with respect to the connector housing 82, and in the direction of the axis L2 of the connector connection portion 23. Movement is regulated. Therefore, the control circuit board 51 is held with respect to the connector housing 82 by the board holding member 92. Further, as shown in FIGS. 13 and 18, a portion of the positioning portion 84a adjacent to the control circuit board 51 is inserted into the positioning notch 92d. Then, the movement of the substrate holding member 92 in the direction parallel to the insertion direction X with respect to the connector housing 82 is restricted by the front end surface of the positioning portion 84a coming into contact with the bottom surface 92e of the positioning notch portion 92d. Further, the end portion on the first connection terminal 51 a side of the control circuit board 51 arranged with respect to the connector housing 82 protrudes outside the connector housing 82 from the connection opening 83 a.

  As shown in FIGS. 13 and 5, the connector module 81 configured as described above inserts the substrate holding member 92 holding the control circuit board 51 into the insertion opening 12 c from the front end side of the substrate holding member 92. However, it is inserted into the fixing portion 12a along the insertion direction X. At this time, the insertion guide convex portion 12k is inserted into the insertion guide portion 37 of the substrate holding member 92, and the substrate holding member 92 includes the first axial positioning projection 12m and the second axial positioning projection. 12n. Further, the seal member 28 provided on the connection opening end face 83b is in close contact with the outer periphery of the insertion opening 12c in the fixed portion 12a. The connector module 81 is fixed to the gear housing 12 by the snap engagement of the four locking claws 39 of the connector housing 82 with the locking projections 12p of the gear housing 12.

Next, the manufacturing method of the connector module 81 of this embodiment is demonstrated.
First, as shown in FIGS. 19A and 19B, a connector housing forming step for forming the connector housing 82 is performed. In the connector housing forming step (supporting step), the terminal material 61 is placed in a forming die (not shown) for forming the connector housing 82. Then, the molten insulating resin material is filled into the mold in which the terminal material 61 is disposed. When the insulating resin material filled in the mold is cooled and solidified, the connector housing 82 supporting the terminal material 61 is formed. In the formed connector housing 82, the portion 61 a connecting the connector terminals 32 in the terminal material 61 overlaps the cutting through hole 33, so that it is not embedded in the resin material constituting the connector housing 82. It is exposed from the through-hole 33 for cutting.

  Next, a terminal cutting step of separating the terminal material 61 to form the connector terminal 32 is performed. In this terminal cutting step, as in the first embodiment, after the connector housing 82 is placed on a die (not shown) used for pressing, a punch is inserted into the cutting through-hole 33 to form the terminal material 61. The part 61a which connects the connector terminals 32 in FIG. That is, the portion 61 a connecting the connector terminals 32 in the terminal material 61 is cut from the connection opening 83 a and the outer opening of the cutting through hole 33.

  Next, a connector boot forming step (waterproof member forming step) for forming the connector boot 25 is performed. In the connector boot forming step, the connector housing 82 is placed in a mold for molding the connector boot 25, and then the molten elastomer is filled in the mold. Then, the elastomer in the mold is cooled and solidified, whereby the connector boot 25 is integrally formed with the connector housing 82 as shown in FIG. In the connector boot forming step, simultaneously with the molding of the connector boot 25, the seal member 28 is integrally formed on the connection opening end face 83b, and the embedded recess 86 is filled with elastomer to form the seal member 87.

  Next, as shown in FIGS. 17A and 17B, a control circuit unit forming step for forming the control circuit unit 91 is performed. In the control circuit unit formation step, first, the control circuit board 51 is inserted into the board holding member 92. Thereafter, the second connection terminal 51 b of the control circuit board 51 held by the board holding member 92 is inserted into the first through hole 54 a of the relay member 54 from the thickness direction of the relay member 54. At this time, the base end surface of the substrate holding member 92 abuts the relay member 54, and the two holding projections 92c of the substrate holding member 92 are inserted into the projection insertion holes 54d of the relay member 54, whereby the control circuit board is obtained. 51 is supported with respect to the relay member 54. Further, the control circuit board 51 makes a right angle with the relay member 54. Further, the terminals of the noise prevention element 53 are inserted into the two pairs of third through holes 54 c of the relay member 54 from the thickness direction of the relay member 54, respectively. At this time, the two noise prevention elements 53 are disposed on the surface on the side where the control circuit board 51 is disposed, of both surfaces in the thickness direction of the relay member 54. Then, soldering is performed to electrically connect the second connection terminal 51 b and the terminals of the noise prevention element 53 to the relay member 54. Thus, the control circuit unit 91 is completed. The order in which the control circuit board 51 and the noise prevention element 53 are assembled to the relay member 54 may be changed as appropriate.

  Next, a control circuit unit insertion process (support process and arrangement process) for inserting the control circuit unit 91 into the connector housing 22 is performed. In the control circuit unit insertion step, as shown in FIG. 13, the control circuit unit 91 is connected to the connection recess in the direction opposite to the insertion direction X from the relay member 54 while maintaining the state where the relay member 54 is orthogonal to the insertion direction X. 83 is inserted. The control circuit unit 91 inserts the plurality of connector terminals 32 protruding from the terminal protruding portion 84b into the second through hole 54b of the relay member 54, while the relay member 54 contacts the positioning convex portion 84c (see FIG. 15). Until the connector housing 82 is moved in the direction opposite to the insertion direction X. When the relay member 54 comes into contact with the positioning convex portion 84c, the base end portion of the substrate holding member 92 holding the control circuit substrate 51 is inserted into the substrate insertion portion 83c. At the same time, as shown in FIGS. 13 and 18, a portion of the positioning portion 84a adjacent to the control circuit board 51 is inserted into the positioning notch 92d and abuts against the bottom surface 92e of the positioning notch 92d. Further, the two noise prevention elements 53 are accommodated in the element accommodating portion 83d. Then, as shown in FIG. 16A, inside the connector housing 82, the relay member 54 is orthogonal to the insertion direction X (that is, the thickness direction of the relay member 54 and the insertion direction X are parallel). At the same time, it is perpendicular to the control circuit board 51. Moreover, the relay member 54 is supported with respect to the connector housing 82 by the positioning convex part 84c and the board | substrate holding member 92 inserted in the board | substrate insertion part 83c.

  Next, a terminal connection process (connection process) for electrically connecting the connector terminal 32 and the relay member 54 is performed. In the terminal connection step, the connector terminal 32 and the relay member 54 are electrically connected from the connection opening 83a by solder. Thus, the connector module 81 is completed.

As described above, according to the second embodiment, the following operational effects are obtained.
(1) In the connector housing forming step, the terminal material 61 is placed in the mold and the terminal material 61 is embedded in the connector housing 82 to support the terminal material 61 with respect to the connector housing 82. Therefore, the connector terminal 32 can be supported with respect to the connector housing 82 more easily than when the plurality of connector terminals 32 separated from each other are supported with respect to the connector housing 82. In the terminal cutting step, the terminal material 61 can be cut inside the connector housing 82 by using two openings, that is, the connection opening 83 a and the outer opening of the cutting through-hole 33. Therefore, the connector housing 82 and the terminal material 61 can be prevented from having complicated shapes, and the terminal material 61 can be easily cut. Furthermore, the electrical connection between the connector terminal 32 and the relay member 54 is easily performed because the connector terminal 32 and the relay member 54 are supported with respect to the connector housing 82. From these things, the connector module 81 can be manufactured easily.

  (2) Since the cutting through hole 33 is formed so as to communicate the outside of the connector housing 82 and the inside of the connection recess 83, the connector terminals 32 in the terminal material 61 are connected to each other in the terminal cutting step. The portion 61a that is present can be easily cut from the outside of the connector housing 22 and the inside of the connector housing 22 (ie, the inside of the connection recess 83).

  (3) In the connector boot forming step, the cutting through hole 33 is closed by the seal member 87, so that liquid can be prevented from entering the connector housing 82 from the cutting through hole 33. Further, since the seal member 87 is formed at the same time as the connector boot 25 in the connector boot formation step, the cutting through hole 33 can be easily closed by the seal member 87.

  (4) Since the connector boot 25, the seal member 28, and the seal member 87 are integrated, the manufacturing apparatus for integrally forming the connector boot 25, the seal member 28, and the seal member 87 into the connector housing 22 has a complicated configuration. It is suppressed. As a result, the cost for manufacturing equipment for forming the connector boot 25, the seal member 28, and the seal member 87 can be reduced.

  (5) The connector housing 82 does not include an opening that needs to be closed by the lid body 41 of the first embodiment. Therefore, since the number of parts of the connector module 81 can be reduced, the manufacturing cost can be reduced.

Each embodiment of the present invention may be modified as follows.
In the second embodiment, in the connector boot forming step, the connector boot 25 is integrally formed with the connector housing 82, and at the same time, the cutting through hole 33 is closed with the seal member 87. However, the formation of the connector boot 25 and the closing of the cutting through hole 33 by the seal member 87 may be performed separately. Further, the cutting through hole 33 is not limited to the seal member 87 formed integrally with the connector housing 82, and may be closed by a lid that is formed separately from the connector housing 82 and is fitted into the cutting through hole 33.

  In each of the above embodiments, the connector boot 25, the seal member 28, and the seal member 87 are all formed of an elastomer.

  In the first embodiment, the lid body 41 is joined to the insertion opening end surface 27b by ultrasonic welding. However, the lid body 41 may be joined to the insertion opening end face 27b by laser welding. Even if it does in this way, the effect similar to (4) of the said 1st Embodiment can be acquired. Further, the lid body 41 is not necessarily fixed to the connector housing 22 by welding. For example, an engaging claw is formed on the lid 41 and an engaging convex portion is formed on the connector housing 22, and the engaging claw and the engaging convex portion are snap-fit engaged with each other to connect the lid 41 to the connector. It may be fixed to the housing 22.

  In the first embodiment, the flange portion 42 of the lid body 41 is welded to the insertion opening end surface 27b, so that the space between the insertion opening end surface 27b and the lid body 41 is sealed. However, a seal member may be interposed between the insertion opening end surface 27b and the flange portion 42 to seal the space between the insertion opening end surface 27b and the lid body 41 in a liquid-tight manner. In this case, if the seal member is integrally formed with at least one of the insertion opening end face 27b and the flange portion 42, the number of parts is reduced. Further, when the control circuit board 51 or the like is assembled to the connector housing 22, the seal member does not fall off from the connector housing 22 or the lid body 41. Fixing can be performed more easily. The seal member may be provided separately from the connector housing 22 and the lid body 41.

-The shape of the cover body 41 is not restricted to the shape of the said 1st Embodiment. Any shape that can close the insertion opening 27a may be used.
In the first embodiment, the second connection terminal 51b, the connector terminal 32, the terminals of the noise prevention element 53, and the relay member 54 are electrically connected simultaneously.

Inclined. However, the insertion opening end surface 27b may be inclined with respect to the insertion direction X to such an extent that the connection portion between the second connection terminal 51b and the relay member 54 does not protrude from the insertion opening 27a to the outside of the connector housing 22. . Further, the insertion opening end face 27b may be formed to be orthogonal to the insertion direction X.

  In the first embodiment, the connection recess 26 and the insertion recess 27 are recessed in parallel with the insertion direction X. However, the insertion recess 27 does not necessarily have to be recessed in parallel with the insertion direction X. Further, the insertion opening 27a may be formed on any one of a plurality of side surfaces of the connector housing 22.

  In the first embodiment, the connector housing 22 has the positioning surface 30 and the positioning pins 31 that support the relay member 54. However, the configuration of the support portion provided in the connector housing 22 to support the relay member 54 is not limited to this. For example, a caulking pin that extends parallel to the insertion direction X may be formed on the positioning surface 30. In this case, the relay member 54 is formed with a caulking hole that penetrates the relay member 54 in the thickness direction, and a caulking pin is inserted into the caulking hole. When the tip end portion of the caulking pin is crushed by heat caulking, the relay member 54 cannot move in the flat plate direction of the relay member 54 with respect to the connector housing 22 by the caulking pin and is parallel to the insertion direction X. Supported by immovable. Moreover, you may form the positioning surface 30 and the positioning pin 31 which support the relay member 54 in the connector housing 82 of 2nd Embodiment, or may form a crimp pin.

However, the electrical connection between the relay terminal 54 and the terminals of the second connection terminal 51b, the connector terminal 32, and the noise prevention element 53 is not limited to soldering. For example, press-fit terminals may be used. In addition, when using a press fit terminal, a relay member arrangement | positioning process also serves as a connection process. Moreover, you may electrically connect the terminal of the 2nd connection terminal 51b, the connector terminal 32, and the noise prevention element 53, and the relay member 54 by welding.

  In the connector housing forming process of each of the above embodiments, the terminal material 61 is disposed in the molding die. However, in the connector housing forming step, the connector housings 22 and 82 in which the terminal material 61 is not insert-molded may be formed. In this case, after the connector housing forming step, a supporting step of supporting the terminal material 61 with respect to the formed connector housings 22 and 82 is performed.

In the second embodiment, the control circuit unit forming step may be performed simultaneously with the connector housing forming step, the terminal cutting step, and the connector boot forming step.

However, in the terminal cutting step of the first embodiment, a cutting jig (such as a cutter) is inserted from either one of the connection opening 26a and the insertion opening 27a to connect the connector terminals 32 in the terminal material 61 to each other. You may cut | disconnect the site | part 61a which is connected. Further, in the terminal cutting step of the second embodiment, a cutting jig (cutter or the like) is inserted from one of the connection opening 83a and the outer opening of the cutting through hole 33, and the terminal material 61 A portion 61a connecting the connector terminals 32 may be cut.

  In the first embodiment, the control circuit board 51, the noise prevention element 53, and the relay member 54 are all assembled to the connector housing 22 from the insertion direction X (from the insertion opening 27a side). However, the assembly direction of the control circuit board 51, the noise prevention element 53, and the relay member 54 with respect to the connector housing 22 is not limited to the insertion direction X. The control circuit board 51, the noise prevention element 53, and the relay member 54 may be assembled to the connector housing 22 from the direction opposite to the insertion direction X (from the connection opening 26 a side) according to the shape of the connector housing 22.

  In each of the above embodiments, the seal member 28 may be formed separately from the connector housings 22 and 82. Further, the seal member 28 may be formed integrally with the insertion opening end face 12d. Further, the motor does not necessarily include the seal member 28.

  In each of the above embodiments, all the electronic components (the control circuit board 51 and the noise prevention element 53) mounted on the relay member 54 are all disposed on the surface of the relay member 54 on the insertion direction X side. However, each electronic component may be arranged on any one of both surfaces in the thickness direction of the relay member 54.

  In each embodiment described above, the relay member 54 is disposed so as to be orthogonal to the insertion direction X. However, the relay member 54 may be arranged so as to be perpendicular to the control circuit board 51 and parallel to the insertion direction X. Further, the relay member 54 is not necessarily arranged so as to be perpendicular to the control circuit board 51.
