[0009] PROBLEMS TO BE SOLVED BY THE INVENTION

[0010] In the above-described technique, there is known a technique in which, for example, a printed circuit board (PCB) provided in a multi-layer current passing shape or the like is used to electrically connect the sensor, the electronic component, and a connection terminal connected to an apparatus outside. At this time, for example, a columnar connection terminal is inserted into a hole portion provided in a base film of the printed circuit board and is soldered, thereby being electrically connected to the printed circuit board.

[0011] However, in the case where the columnar connection terminal is inserted into the hole portion of the printed circuit board and is soldered, solder sometimes leaks out of the hole portion and flows between the columnar terminal and the housing of the rotating device. In this case, the fixing of the terminal to the housing becomes unstable due to the columnar terminal being suspended from the housing.

[0012] An object of one aspect of the present application is to provide a wiring substrate, a rotating apparatus, and a rotating device that can suppress leakage of solder from a hole portion.

[0013] Solution to the problem

The inner peripheral end portion of the base is disposed inside the portion that surrounds the hole portion. The inner peripheral end portion of the base is deformed in a direction that passes through the hole portion.

[0015] According to one aspect, leakage of solder from the hole portion can be inhibited. BRIEF DESCRIPTION OF DRAWINGS

[0039] Hereinafter, the wiring substrate, the rotary device, and the rotary device disclosed in the present application will be described with reference to the drawings. Note that the dimensional relationship of each element, the ratio of each element, and the like in the drawings can sometimes be different from the actual ones. Sometimes, the drawings can include portions different from each other in the dimensional relationship and the ratio. In each drawing, in order to facilitate understanding of the explanation, a three-dimensional orthogonal coordinate system in which the axial direction of the output shaft 51 to be described later is the positive direction of the Z axis (the rotational axis direction) can sometimes be illustrated.

[0040] [First Embodiment]

[0041] Figure 1 is a plan view of the rotary device in the first embodiment, Figure 2 is a side view of the rotary device in the first embodiment, Figure 3 is a bottom view of the rotary device in the first embodiment. Furthermore,Figure 4 is a plan view of the rotary device in the first embodiment with the first housing removed. Furthermore, Figure 20 is a schematic explanatory view showing an air conditioning system equipped with the rotary device of the embodiment.

[0042] The rotary device 1 of the embodiment can be used as an actuator for an air conditioning system for a vehicle or the like, for example, and can control the rotational movement of a louver for controlling the air volume or the like.

[0043] The rotary device 1 of the embodiment is used in an air conditioning system 100 for a vehicle or the like as shown in Figure 20 , for example, and can control the rotational movement of a louver 104 for controlling the air volume or the like. The air conditioning system 100 for a vehicle is equipped with a blower 101, an evaporator 102 that cools air sent from the blower 101, and a heater 103 disposed downstream of the evaporator 102. Furthermore, a louver 104 that controls the supply amount of air flowing from the evaporator 102 side to the heater 103 side is disposed between the evaporator 102 and the heater 103, and a drive shaft 104a of the louver 104 is rotated by the rotary device 1.

[0044] As shown in Figures 1-4 , the rotary device 1 is equipped with a housing 2 in which a power transmission mechanism portion is accommodated. Here, the power transmission mechanism portion is specifically composed of a motor 3 as shown in Figure 4 , a plurality of gears (hereinafter referred to as a gear set) 6 that transmit power from the motor 3, a sensor 7 that detects the rotation angle of an output gear 5 included in the gear set 6, and the like. Note that the sensor 7 can detect not only the rotation angle but also the rotational speed of the output gear 5.

[0045] The gear set 6 of the power transmission mechanism portion includes a worm 32 attached to a rotation shaft 31 of the motor 3, a first transmission gear 61, a second transmission gear 62, and the output gear 5. That is, as shown in Figure 4 , the rotation of the worm 32 is transmitted to a helical gear 611 of the first transmission gear 61, and is transmitted to a helical gear 621 of the second transmission gear 62 via a small-diameter gear 612 that is disposed coaxially with the helical gear 611 and has a smaller diameter than the helical gear 611. Furthermore, the rotation of the second transmission gear 62 is transmitted to the output gear 5 via a small-diameter gear (not shown) that is disposed coaxially with the helical gear 621 and has a smaller diameter than the helical gear 621, for example. In addition, the output gear 5 is connected to an output shaft 51( Figure 3 ). The output gear 5 engages an external shaft such as the drive shaft 104a of the louver 104 of the above-described air conditioning system 100, for example. Therefore, the rotational movement of the louver 104 can be controlled by rotating the output gear 5, and the adjustment of the air volume or the like of the air conditioning system 100 can be performed (see Figure 20 ).

[0046] Thus, the rotation of the motor 3 is decelerated at a predetermined deceleration ratio and is output to the outside from the output shaft 51. Also, the rotation angle of the output gear 5 is detected by the sensor 7. The information of the rotation angle of the output gear 5 detected by the sensor 7 is transmitted to the outside via the five connection terminals 4a to 4e shown in Figs. 1 and 2. Figure 2 and Figure 4 The need to explain, in the case of a plurality of connection terminals 4 is expressed in a manner to distinguish, respectively, sometimes will be recorded as connection terminals 4a to 4e. In addition, the connection terminals 4 is an example of a conductive member of the column.

[0047] Need to explain, in the sensor 7 in the present embodiment, for example, can be used in a rotational resistance position sensor, which detects the resistance value generated by the brush relative to the conductive part of the contact position in the circumferential displacement by the sensor substrate and conductive brush. However, the structure of the sensor 7 need not be limited to the structure of the present embodiment. In addition, although in the present embodiment the motor 3 adopts a direct current (DC) motor, but also can be a brushless motor, stepper motor. In the case of a brushless motor, stepper motor, the rotating device 1 does not need the sensor 7 also no harm.

[0048] As shown in Figures 1-3 , the housing 2 has a first housing 21 and a second housing 22. That is, the housing 2 is composed by linking the first housing 21 ( Figure 1 ) and the second housing 22 ( Figure 3 ). Need to explain, here, in the case of the position relationship between the top and bottom, with the first housing 21 of the rotating device 1 relative to the upper side (Z axis positive direction side) and the second housing 22 relative to the lower side (Z axis negative direction side) as the basis.

[0049] As shown in Figure 1 and Figure 2 , the first housing 21 has a first face 210 constituting the top surface of the housing 2 and a first side wall 211 provided on the outer peripheral portion of the first face 210. On the other hand, as shown in Figure 2 and Figure 3 , the second housing 22 has a second face 220 constituting the bottom surface of the housing 2 and a second side wall 221 provided on the outer peripheral portion of the second face 220. Need to explain, the housing 2 is formed of a resin material such as polypropylene, polyethylene terephthalate, ABS.

[0050] In addition, as shown in Figure 1 and Figure 2 , in the first housing 21, a plurality of engagement portions 212 extending to the second housing 22 side are formed integrally with the outer peripheral portion of the first side wall 211. On the other hand, as shown in Figure 1 andFigure 4 As shown in FIG. 2, the second housing 22 is formed with a plurality of protrusions (hereinafter referred to as engaging protrusions) 222 corresponding to the plurality of engaging portions 212 of the first housing 21, respectively, integrally with the second side wall portion 221. The engaging protrusions 222 are engaged with the engaging portions 212.

[0051] Thus, the housing 2 is formed by butting the first housing 21 and the second housing 22 (see FIG. 1). That is, by engaging the engaging protrusions 222 of the second housing 22 with the engaging portions 212 of the first housing 21, the first housing 21 and the second housing 22 are integrated, constituting the housing 2 which accommodates the power transmission mechanism portion having the motor 3, the gear set 6, and the like. Figure 2 ). That is, by engaging the engaging protrusions 222 of the second housing 22 with the engaging portions 212 of the first housing 21, the first housing 21 and the second housing 22 are integrated, constituting the housing 2 which accommodates the power transmission mechanism portion having the motor 3, the gear set 6, and the like.

[0052] Note that, although the present embodiment is configured such that the engaging portions 212 are provided in the first housing 21 and the engaging protrusions 222 are provided in the second housing 22, the present embodiment can be configured such that the engaging portions 212 are provided in the second housing 22 and the engaging protrusions 222 are provided in the first housing 21.

[0053] Further, as shown in FIG. 2, engaging pieces 93 which protrude outward are formed at both ends of one side of the first housing 21 and the second housing 22. Linking holes 94 through which fasteners (not shown) as prescribed fixing members are inserted are provided in the engaging pieces 93, and the first housing 21 and the second housing 22 which have been engaged are firmly linked by the prescribed fasteners through the four linking holes 94, constituting the integrated housing 2. Figures 1-3 In the configuration of the housing 2 described above, in the present embodiment, the protruding portions 28 are provided at the corners of the first side wall portion 211 which constitutes the outer peripheral portion of the first housing 21, and the second through holes 282 are provided at the corners of the second housing 22. That is, in the first housing 21, the protruding portions 28 which are cylindrical are formed so as to protrude from the first face portion 210, and the protruding portions 28 have first through holes 281 through which fasteners (not shown) such as bolts and screws can be inserted. Further, the second housing 22 is provided with the second through holes 282 into which the protruding portions 28 are fitted.

[0054] A plurality of protruding portions 28 are provided, and a plurality of second through holes 282 are provided in correspondence thereto. The plurality of protruding portions 28 are provided at the plurality of (four) corners of the first housing 21, and the plurality of second through holes 282 are provided at the plurality of (four) corners of the second housing 22. In the present embodiment, the first face portion 210 of the first housing 21 and the second face portion 220 of the second housing 22 are substantially rectangular in plan view, and the protruding portions 28 and the second through holes 282 are provided at the corners of the four corners, respectively.

[0055] As shown in FIG. 2, engaging pieces 93 which protrude outward are formed at both ends of one side of the first housing 21 and the second housing 22. Linking holes 94 through which fasteners (not shown) as prescribed fixing members are inserted are provided in the engaging pieces 93, and the first housing 21 and the second housing 22 which have been engaged are firmly linked by the prescribed fasteners through the four linking holes 94, constituting the integrated housing 2.

[0056] Figure 3 ​As shown, the second housing 22 is formed with a second through-hole 282 at a portion corresponding to a corner of the second side wall portion 221. An engaging piece 93 is provided outside the corner of the second side wall portion 221.

[0057] Further, as Figures 1-3 shown, the first housing 21 and the second housing 22 are respectively formed with protruding portions 219, 229 corresponding to each other. In the present embodiment, the protruding portions 219, 229 protrude in a direction in which the connection terminals 4 extend. These protruding portions 219, 229 are engaged with each other to form a connector portion 200 Figure 2 ) in which the connection terminals 4 are held. As Figure 2 shown, the connector portion 200 holds a plurality of (for example, five) connection terminals 4. Note that the protruding portion 229 is one example of a portion of a housing.

[0058] As Figure 4 shown, the connection terminal 4 is, for example, a columnar conductive member provided with a flange 41. A plurality of connection terminals 4 are, for example, arranged in the protruding portion 229 of the second housing 22. At this time, as will be described later, the connection terminals 4 are arranged, for example, in such a manner that the flanges 41 are fitted into groove portions 228 formed in holding portions 225 provided in the protruding portion 229 of the second housing 22. Further, as will be described later, the connection terminals 4 are pressed by first and second protruding portions 216a to 216e and 217a to 217e formed in a pressing portion 215 provided in the protruding portion 219 of the first housing 21.

[0059] Further, as Figure 4 shown, the rotation device 1 of the present embodiment is provided with a flexible wiring substrate 8 as a substrate that electrically connects the connection terminals 4 with the motor 3 and the sensor 7. Via the wiring substrate 8 and the connection terminals 4, an input / output signal for driving the motor 3 can be acquired from the outside, and a signal corresponding to the rotation angle of the output gear 5 from the sensor 7 can be output to the outside. Note that, here, electrical connection is a concept including a case in which two members are directly connected and a case in which connection is made via other members.

[0060] The wiring substrate 8 is, for example, a so-called flexible printed circuit (FPC: Flexible Printed Circuit) formed of a film sheet having flexibility. Generally, a flexible printed circuit is constituted of a base film (base body), a wiring, and a cover film. Note that, hereinafter, the cover film is not illustrated.

[0061] The flexible wiring substrate 8 has a configuration in which an adhesive layer is formed on a base film (resin substrate) having a thickness of about 12 μm to 50 μm, for example, and a conductor having a thickness of about 12 μm to about 50 μm is printed or attached on the adhesive layer. The base film is formed of a resin material having insulating properties such as polyimide, polyester, or the like. Further, the conductor is formed of a metal material such as copper. Note that the adhesive layer is formed of an epoxy-based resin, an acrylic-based resin. The wiring substrate 8 is a flexible substrate that can be bent and restored to a state before being bent even when bent at an angle of 90 degrees or more. Note that the conductor is one example of a wiring.

[0062] As shown in Figure 4 , the wiring substrate 8 has substantially three flat portions 81, 82, and 83. Specifically, the wiring substrate 8 has a first flat portion 81 to which the connection terminal 4 and the sensor 7 are connected, a third flat portion 83 on the side to which the terminal 33 of the motor 3 is connected, and a second flat portion 82 connecting the first flat portion 81 and the third flat portion 83.

[0063] Figure 5 is a perspective view of the wiring substrate in the first embodiment. Figure 6 and Figure 7 is a perspective view of the wiring substrate mounted on the rotating device in the first embodiment. Further, Figure 8 is a cross-sectional view of the wiring substrate mounted on the rotating device in the first embodiment. Note that Figure 5 in which the second flat portion 82 and the third flat portion 83 are omitted.

[0064] The first flat portion 81 has a base 813 and a wiring 84. The wiring 84 is formed on the first flat portion 81 on the first face 811 side. Note that, as shown in Figure 5 and Figure 8 , a reinforcing member 90 such as a support plate is provided on the second face 812 side of the first flat portion 81 of the wiring substrate 8 as a member different from the wiring substrate 8. Note that the reinforcing member 90 is one example of a member different from the wiring substrate.

[0065] The base 813 is formed with a plurality of hole portions H1 through which one end portion 49 of the connection terminal 4 is inserted. By inserting the connection terminal 4 in these hole portions H1 and performing soldering, reliable electrical connection can be performed. That is, the connection terminal 4 is electrically connected to the wiring substrate 8 by solder S. Each of the hole portions H1 of the wiring substrate 8 is formed by inner peripheral end portions 81a to 81e that are portions of the base 813 as will be described later. Note that the solder S is one example of an electrically conductive member provided on the first face.

[0066] As shown in Figure 6 and Figure 7As shown, the wiring substrate 8 is arranged, for example, such that the first flat portion 81 is positioned between the sensor 7 and the connection terminal 4. Further, as shown in FIG. 2, the wiring substrate 8 is arranged, for example, such that the second flat portion 82 is positioned between the connection terminal 4 and the motor 3. Figure 8 As shown, in the first flat portion 81, a bent portion 800 is formed between an end portion where the hole portion H1 is formed that is connected to the connection terminal 4 and another end portion 819 that is connected to the sensor 7.

[0067] In each hole portion H1 of the wiring substrate 8, each connection terminal 4 is inserted, for example, to the positive direction side of the Y axis. The plurality of connection terminals 4 are arranged, for example, in a manner in which they are aligned in a direction that intersects the direction of insertion (in the embodiment, the orthogonal direction (X axis direction)). As described above, the connection terminal 4 that is inserted into the hole portion H1 is soldered to the wiring substrate 8, for example, and is fixed to the wiring substrate 8 by the solder S. The same number of hole portions H1 as the number of connection terminals 4 are formed, for example.

[0068] In the first flat portion 81 of the wiring substrate 8, the first face 811 and the second face 812 are in a relationship in which the first face 811 is the front face and the second face 812 is the back face, for example, in a direction in which the connection terminal 4 passes (the positive direction of the Y axis). The second face 812 is a face that is on the opposite side of the first face 811. The second face 812 side of the first flat portion 81 of the wiring substrate 8 opposes a portion of the housing 2. In the embodiment, the second face 812 side opposes the protruding portion 229 that is a portion of the housing 2, with the reinforcing member 90 interposed therebetween.

[0069] As described above, the wiring 84 is formed on the first face 811 side of the wiring substrate 8. The wiring 84 has five first pads 85a to 85e that are portions that are electrically connected to the connection terminal 4. Note that, hereinafter, in cases in which expression is made without distinguishing between the plurality of first pads 85a to 85e, it will sometimes be referred to as the first pad 85. The first pad 85 is formed on a portion that surrounds each hole portion H1. Further, the size of the connection terminal 4 is larger than the hole portion H1, for example, and is smaller than the portion that is surrounded by the first pad 85. Note that the first pad 85 is one example of an electrically conductive member.

[0070] The wiring 84 extends to the other end portion 819 of the first flat portion 81, for example, via the bent portion 800. The wiring 84 that is formed on the other end portion 819 has a second pad 86 that is a portion that is electrically connected to the sensor 7. The second pad 86 is connected to a terminal provided on the sensor 7 by solder S, for example. That is, the terminal of the sensor 7 is electrically connected to the wiring substrate 8 by being soldered to the second pad 86 that is provided on the other end portion 819 of the first flat portion 81.

[0071] Further, the wiring 84 extends to the third flat portion 83 via the second flat portion 82 of the wiring substrate 8. The wiring 84 that is formed on the third flat portion 83 has a third pad (not shown) that is a portion that is electrically connected to the terminal 33 of the motor 3.

[0072] Next, the connection of the wiring substrate 8 and the connection terminal 4 will be described. Figure 9 is a plan view of the first planar portion of the wiring substrate in the first embodiment. Further, Figure 10A is a sectional view at the A-A line of Figure 9 , Figure 10B is a sectional view at the B-B line of Figure 9 , Figure 10C is a sectional view at the C-C line of Figure 9 . In Figure 9 , the upper stage shows a view of the state before the connection terminal 4 is attached, the middle stage shows a view of the state before soldering after the connection terminal 4 is attached, and the lower stage shows a view of the state after the connection terminal 4 is soldered. That is, Figure 10A shows a view of the state before the connection terminal 4 is attached, Figure 10B shows a view of the state before soldering after the connection terminal 4 is attached, Figure 10C shows a view of the state after the connection terminal 4 is soldered.

[0073] As shown in Figure 9 and Figure 10A , the first planar portion 81 has, for example, inner peripheral end portions 81a to 81c and inner peripheral end portions 81d and 81e, which are not shown. The inner peripheral end portion 81a is formed on the inner side of the first land 85a, which is formed on the portion of the wiring 84 that surrounds the hole portion H1. Similarly, the inner peripheral end portions 81b to 81e are formed on the inner sides of the first lands 85b to 85e, which are formed on the portion of the wiring 84 that surrounds the hole portion H1. That is, the inner peripheral end portions 81a to 81e are formed at the positions where the hole portion H1 is formed.

[0074] As described above, the inner peripheral end portions 81a to 81e, which are parts of the first planar portion 81 of the wiring substrate 8, are formed of a material that can be bent. Further, the hole portion H1 formed by the inner peripheral end portions 81a to 81e is smaller in size than the connection terminal 4. Thus, when the connection terminal 4 is inserted into the hole portion H1, the inner peripheral end portions 81a to 81e are deformed in the direction in which the connection terminal 4 passes through the hole portion H1.

[0075] As shown in Figure 10B , when the connection terminal 4 is inserted into the hole portion H1, the inner peripheral end portion 81b is deformed in the direction D (the positive direction of the Y axis) in which the connection terminal 4 passes through the hole portion H1. The deformed inner peripheral end portion 81b comes into contact with the outer peripheral surface of one end portion 49 of the connection terminal 4.

[0076] Next, when the connection terminal 4 is soldered to the first planar portion 81 of the wiring substrate 8, as shown in Figure 9 and Figure 10CAs shown, the solder S is arranged at a position overlapping the first land 85c. In this case, the inner peripheral end portion 81c that has been deformed in the direction D (positive direction of the Y axis) in which the connection terminal 4 passes through the hole portion Hl inhibits the solder S from flowing in the direction opposite to the direction D (negative direction of the Y axis). Thus, the wiring substrate 8 in the present embodiment can inhibit the solder from leaking from the hole portion Hl.

[0077] Further, a structure is known in which, for example, a connection terminal that connects the sensor, the electronic component, and an external device is electrically connected to a printed circuit board (PCB) provided in a multi-layer power feeding shape. At this time, for example, a columnar connection terminal is fixed to a housing of a rotating device or the like.

[0078] However, when the columnar connection terminal is fixed to the housing or the like, positional displacement is likely to occur. The positional displacement when the connection terminal is fixed to the housing can cause the connection terminal to shake.

[0079] Therefore, in the present embodiment, the connection terminal 4 is held by the holding portion 225 of the second housing 22 and the pressing portion 215 of the first housing 21. The pressing portion 215 forms a part of the inner wall portion of the housing 21. The pressing portion 215 functions as the inner wall portion to inhibit a connector (a connected terminal) of an external device (not shown) from being further inserted into the inside of the housing 2 when the connector is inserted into the connector portion 200. That is, the pressing portion 215 is a portion that forms a space that encloses a part other than the insertion port 201 (an opening portion) through which the connector of the external device is inserted into the connector portion 200. Figure 11 is a perspective view of a protruding portion of the first housing in the first embodiment. Figure 12 is a perspective view of a holding portion of the second housing in the first embodiment, Figure 13 is a perspective view of a pressing portion of the first housing in the first embodiment.

[0080] As shown in Figure 11 and Figure 13 in the present embodiment, the pressing portion 215 provided with the first protruding portions 216a to 216e and the second protruding portions 217a to 217e is formed in the protruding portion 219 of the first housing 21. Further, as shown in Figure 6 and Figure 12 in the present embodiment, the holding portion 225 provided with the groove portion 228, the first holding grooves 226a to 226e, and the second holding grooves 227a to 227e is formed in the protruding portion 229 of the second housing 22. Note that, Figure 12 shows a view in which a portion corresponding to reference sign U1 in Figure 6 is enlarged, Figure 13 shows a view in which a portion corresponding to reference sign U2 in Figure 11A view of a portion corresponding to reference sign U2 is enlarged. Further, hereinafter, in a case where expression is made without distinguishing the first protruding portions 216a to 216e, it is referred to as the first protruding portion 216, and in a case where expression is made without distinguishing the second protruding portions 217a to 217e, it is referred to as the second protruding portion 217. Further, hereinafter, in a case where expression is made without distinguishing the first holding grooves 226a to 226e, it is referred to as the first holding groove 226, and in a case where expression is made without distinguishing the second holding grooves 227a to 227e, it is referred to as the second holding groove 227. Note that the first protruding portion 216 and the second protruding portion 217 are one example of a convex portion, and the first holding groove 226 and the second holding groove 227 are one example of a concave portion.

[0081] The first protruding portion 216 and the second protruding portion 217 are formed of, for example, the same resin material as the housing 2. In this case, the press portion 215 provided with the first protruding portion 216 and the second protruding portion 217 and the groove portion 218 is integrally formed with the first housing 21, for example, by resin injection molding using a mold. Similarly, the holding portion 225 provided with the groove portion 228, the first holding groove 226, and the second holding groove 227 is integrally formed with the second housing 22, for example, by resin injection molding using a mold.

[0082] As described above, the flange 41 of the connection terminal 4 is inserted in the groove portion 228 of the second housing 22. Further, the portion of the connection terminal 4 other than the flange 41 is held by the first holding groove 226 and the second holding groove 227. The first holding groove 226 and the second holding groove 227 are formed in a manner arranged in the direction (Y-axis positive direction) in which the connection terminal 4 is inserted. In the present embodiment, the first holding groove 226 is formed at a position on the Y-axis negative direction side from the groove portion 228 in the holding portion 225, and the second holding groove 227 is formed at a position on the Y-axis positive direction side from the groove portion 228 in the holding portion 225. That is, the first holding groove 226 and the second holding groove 227 are formed at positions sandwiching the groove portion 228 toward the Y-axis positive direction side.

[0083] Further, the groove portion 218 is formed at a position corresponding to the groove portion 228 of the second housing 22 in the press portion 215 of the first housing 21. The flange 41 of the connection terminal 4 is also inserted in the groove portion 218. Further, the first protruding portion 216 and the second protruding portion 217 are formed at positions corresponding to the first holding groove 226 and the second holding groove 227 of the second housing 22 in the press portion 215. The first protruding portion 216 and the second protruding portion 217 press the connection terminal 4 held in the holding portion 225 of the second housing 22 from the upper direction (Z-axis positive direction). That is, the connection terminal 4 is sandwiched by the first protruding portion 216 and the first holding groove 226, and is sandwiched by the second protruding portion 217 and the second holding groove 227.

[0084] Figure 14 is a sectional view at the line D-D of Figure 13 Figure 15A is a sectional view at the line E-E of Figure 13 Figure 15B is a sectional view at the line F-F of Figure 13 As shown in Figure 14 , a pair of the first protrusions 216 and the second protrusions 217 are formed at positions of the clamping groove portions 218 in a manner of being aligned in an insertion direction (Y-axis positive direction) of the connection terminals 4. That is, the pair of the first protrusions 216 and the second protrusions 217 press the connection terminals 4 downward (Z-axis negative direction) in a manner of being bilaterally supported at positions of the flanges 41 of the clamping connection terminals 4. Thereby, it is possible to suppress the connection terminals 4 from wobbling in the insertion direction (Y-axis positive direction). Further, it is possible to set heights of end portions 48 (end portions located on the side of the opening 201 of the connector portion 200 or the side of the external device) of the connection terminals 4 to prescribed heights. Here, the prescribed heights refer to, for example, distances of the end portions 48 of the connection terminals 4 each from a portion 219a of the first housing and a portion 229a of the second housing each formed in the connector portion 200 and facing each other in the Z-axis direction. Thus, it is possible to insert the connection terminals 4 into a connector of an external device having an arbitrary height and shape. Note that the insertion direction of the connection terminals 4 is a direction in which the connection terminals 4 are inserted into the connector of the external device. Further, the insertion direction of the connection terminals 4 is a long dimension direction of the connection terminals 4.

[0085] Further, as shown in Figure 15A , the first protrusions 216 and the second protrusions 217 are formed as polygons having apexes P1 such as triangles. When the first housing 21 and the second housing 22 are joined, the first protrusions 216 and the second protrusions 217 press the connection terminals 4 held in the first holding grooves 226 and the second holding grooves 227 of the second housing 22 from above (Z-axis positive direction). At this time, the apexes P1 of the first protrusions 216 and the second protrusions 217 are deformed as shown in Figure 15B .

[0086] As shown in Figure 15B , the apexes P2 of the second protrusions 217d and 217e are deformed by being pressed by the connection terminals 4. Further, the second protrusions 217a to 217c and the first protrusions 216 each not shown are also similarly deformed. Thereby, the connection terminals 4 are clamped by the first protrusions 216 and the second protrusions 217 and the first holding grooves 226 and the second holding grooves 227, and thus it is possible to reliably fix the connection terminals 4 to the housing 2.

[0087] ​​As explained above, in the present embodiment, the wiring substrate 8 is provided with: a base 813 having a hole portion Hl and an inner peripheral end portion 81a that forms the hole portion Hl; and a wiring 84 having a portion 85 that surrounds the hole portion Hl. The inner peripheral end portion 81a of the base 813 is disposed inside the portion 85 that surrounds the hole portion Hl. The inner peripheral end portion 81a of the base 813 is deformed in a direction that passes through the hole portion Hl. Thus, leakage of the solder from the hole portion Hl can be suppressed.

[0088] Further, in the present embodiment, the rotating device 1 is provided with: the motor 3; the plurality of gears 6; the plurality of connection terminals 4 for electrical connection with the outside; and the housing 2 that houses the motor 3, the gears 6, and the connection terminals 4. The housing 2 is composed of a first housing 21 and a second housing 22. The second housing 22 has recesses 226, 227 into which the connection terminals 4 are fitted. The first housing 21 is provided with protrusions 216, 217 that protrude toward the connection terminals 4 and the recesses 226, 227. The connection terminals 4 are pressed by the protrusions 216, 217 toward the recesses 226, 227. Thus, the connection terminals 4 can be reliably fixed to the housing 2 while being suppressed from shaking.

[0089] [Second Embodiment]

[0090] Next, the wiring substrate 80 of the second embodiment will be described with reference to the drawings. Note that the wiring substrate 80 of the second embodiment is the same as the wiring substrate 8 of the above-described first embodiment in terms of basic configuration, and the same reference numerals are assigned to the same constituent elements and detailed description will be omitted.

[0091] Figure 16 is a perspective view of the wiring substrate in the second embodiment, Figure 17 is a plan view of the first planar portion of the wiring substrate in the second embodiment, Figure 18 is a perspective view of the wiring substrate in which the connection terminal is inserted in the second embodiment. Note that, Figure 16 and Figure 18 the illustration of the reinforcing member 90 and the second housing 22 is omitted. Further, Figure 18 shows a view of a state before the connection terminal 4 is soldered to the wiring substrate 80.

[0092] As shown in Figure 16 , in the base 871 of the first planar portion 87 of the wiring substrate 80 of the second embodiment, the inner peripheral end portion 87e that forms the hole portion H2 is provided with a plurality of protrusions 87el to 87e4, unlike the wiring substrate 8 of the first embodiment. Note that, hereinafter, in cases where expression is made without distinguishing the plurality of inner peripheral end portions 87a to 87e, it will be sometimes referred to as the inner peripheral end portion 87.

[0093] As shown in Figure 17As shown in the second embodiment, the plurality of protrusions 87a1 to 87a4 protrude from four directions of the hole portion H2. Further, the plurality of protrusions 87a1 to 87a4 are formed on the inner side of the first pad 85a formed on the portion of the wiring 84 surrounding the hole portion H2. Further, in the second embodiment, the hole portion H2 formed by the inner peripheral end portion 87a formed by the plurality of protrusions 87a1 to 87a4 is also smaller than the size of the connection terminal 4. Thus, when the connection terminal 4 is inserted into the hole portion H2, the plurality of protrusions 87a1 to 87a4 forming the inner peripheral end portion 87a are respectively deformed toward the direction in which the connection terminal 4 passes through the hole portion H2. In Figure 17 In the case shown, when the connection terminal 4c is soldered to the first pad 85c, the outflow of the solder S is suppressed by the plurality of protrusions 87a1 to 87a4 that have been deformed.

[0094] As shown in the second embodiment, the plurality of protrusions 87a1 to 87a4 protrude from four directions of the hole portion H2. Further, the plurality of protrusions 87a1 to 87a4 are formed on the inner side of the first pad 85a formed on the portion of the wiring 84 surrounding the hole portion H2. Further, in the second embodiment, the hole portion H2 formed by the inner peripheral end portion 87a formed by the plurality of protrusions 87a1 to 87a4 is also smaller than the size of the connection terminal 4. Thus, when the connection terminal 4 is inserted into the hole portion H2, the plurality of protrusions 87a1 to 87a4 forming the inner peripheral end portion 87a are respectively deformed toward the direction in which the connection terminal 4 passes through the hole portion H2. In Figure 17 As shown in the second embodiment, the plurality of protrusions 87a1 to 87a4 protrude from four directions of the hole portion H2. Further, the plurality of protrusions 87a1 to 87a4 are formed on the inner side of the first pad 85a formed on the portion of the wiring 84 surrounding the hole portion H2. Further, in the second embodiment, the hole portion H2 formed by the inner peripheral end portion 87a formed by the plurality of protrusions 87a1 to 87a4 is also smaller than the size of the connection terminal 4. Thus, when the connection terminal 4 is inserted into the hole portion H2, the plurality of protrusions 87a1 to 87a4 forming the inner peripheral end portion 87a are respectively deformed toward the direction in which the connection terminal 4 passes through the hole portion H2. In

[0095] As described above, in the second embodiment, the inner peripheral end portion 87a of the base 871 has the plurality of protrusions 87a1 to 87a4 protruding toward the inner side of the hole portion H2. The plurality of protrusions 87a1 to 87a4 are arranged in a manner of being arranged in the circumferential direction of the hole portion H2. Thus, the outflow of the solder from the hole portion H2 can be more effectively suppressed.

[0096] The present application has been described based on each embodiment above, but the present application is not limited to each embodiment, and of course various modifications can be made within the scope of the gist of the present application. A person skilled in the art can know from the description of the technical solution that the solution in which such various modifications are made within the scope of the gist is included in the technical scope of the present application.

[0097] Although the rotary device 1 having five connection terminals 4 is described, the number of connection terminals 4 is not limited to five. Also, although the hole portions H1 and H2 are quadrangular, the shape of the hole portions can be changed arbitrarily, for example, according to the shape of the connection terminal. For example, in the case where the cross-sectional shape of the connection terminal is triangular, the hole portion can also be triangular. In this case, for example, in the second embodiment, the inner peripheral end portion 87a can also be formed of three protruding portions 87a1 to 87a3.

[0098] Also, although the first protruding portion 216 and the second protruding portion 217 that press the connection terminal 4 are described as being in the shape of a triangular prism, the shape is not limited to this, and can be other shapes such as a pentagonal prism. Also, the first protruding portion 216 and the second protruding portion 217 can be in the shape of a pyramid such as a triangular pyramid or a quadrangular pyramid. Figure 19 is a perspective view of a pressing portion of the first housing in a modification. As Figure 19 As shown in (b) and (c) of FIG. 21, the first protruding portion 216 and the second protruding portion 217 in the shape of a pyramid can be formed so as to have a plurality of in the direction of insertion of the connection terminal 4 and the direction intersecting the connection terminal 4 (the direction orthogonal to the connection terminal 4 in the embodiment). Also, as shown in (b) and (c) of FIG. 21, the first protruding portion 216 and the second protruding portion 217 can be in the shape of a pyramid such as a triangular pyramid or a quadrangular pyramid. Figure 19 As shown in (b) and (c) of FIG. 21, one of the first protruding portion 216 and the second protruding portion 217 can be in the shape of a pyramid such as a triangular pyramid or a quadrangular pyramid, and the other can be in the shape different from the shape of the one. Also, the shapes of the first protruding portion 216 and the second protruding portion 217 before deformation, or the shapes of the first protruding portion 216 and the second protruding portion 217 after deformation, or the shapes of the first protruding portion 216 and the second protruding portion 217 that do not deform can be different from each other. Also, although the first protruding portion 216 and the second protruding portion 217 are described as extending in the direction of insertion of the connection terminal 4 (the positive direction of the Y axis), the direction is not limited to this, and for example, the first protruding portion 216 and the second protruding portion 217 can extend in other directions such as the direction orthogonal to the direction of insertion of the connection terminal 4 (the direction of the X axis).

[0099] Also, although the first protruding portion 216 and the second protruding portion 217 that press the connection terminal 4 are described as being integrally formed with the first housing 21 by resin injection molding using a mold, the structure is not limited to this, and can be such that the first protruding portion 216 and the second protruding portion 217 formed of other members are joined to the first housing 21. Also, the first protruding portion 216 and the second protruding portion 217 can be formed of a material softer than the material of the connection terminal 4, and can be formed of a material other than resin. Also, the material of the first protruding portion 216 and the second protruding portion 217 is, for example, a material that can be plastically deformed, but the material is not limited to this, and can be a material having elasticity.
