Description

[Technical Field]

[0001] The present invention relates to a connector, a printed circuit board on which the connector is mounted, and an electric motor module including the printed circuit board. [Background technology]

[0002] In vehicles, electric motor modules that drive power windows, sliding doors, sunroofs, power seats, etc. are often provided as an ECU (Electronic Control Unit) that integrally houses an electric motor serving as a drive source and a printed circuit board that mounts electronic components for controlling the motor. In this case, technology related to connectors on the printed circuit board that electrically connect the printed circuit board to the terminals of the electric motor has been conventionally known.

[0003] For example, Patent Document 1 discloses a connector for mounting on a circuit board. This connector includes a base for mounting on the circuit board, a carrier region extending obliquely upward from the base, and a U-shaped receptacle connected to the carrier region at one free end and opening upward for a flat terminal of an electric motor. In particular, this carrier region allows for tolerance of positional errors during assembly of the printed circuit board and the electric motor.

[0004] Patent Document 2 discloses a connector for mounting on a circuit board. This connector includes an insert body that connects to the terminals of an electric motor, a support part that stands alongside the insert body, a U-shaped bent part in the center of the support part and the insert body, a long pin that extends downward from the bottom of the support part, and a short pin that extends downward from the bottom of the insert body. The long pin is inserted into a hole in the printed circuit board and soldered, and the short pin is inserted. This allows for positional errors when assembling the printed circuit board and the electric motor.

[0005] Furthermore, Patent Document 3 discloses an electric motor module including an electric motor, a circuit board, and a housing that houses these. This electric motor module includes components including a first contact connected to a terminal of the electric motor, a second contact connected to the circuit board, and a central portion connecting these contacts. By fixing this central portion to the electric motor, it is possible to prevent the force applied when assembling the electric motor from acting on the second contact.

[0006] [Patent Document 1] German Patent Specification No. 10121430C1 [Patent Document 2] People's Republic of China Patent Publication No. 105870682A [Patent Document 3] International Publication No. 2014016093A2 Summary of the Invention [Problem to be solved by the invention]

[0007] As mentioned above, automotive ECUs require electrical connections via metal terminals when assembling the electric motor and printed circuit board. However, because the printed circuit board is positioned and fixed to the motor housing using an outer case, variations between components can accumulate at the terminals, causing misalignment, which can deform the terminals or damage electrical connections such as solder.

[0008] The present invention provides a connector that allows for misalignment of the connector on a printed circuit board relative to the terminals of an electric motor, reducing the risk of terminal deformation and damage to electrical connections, a printed circuit board on which the connector is mounted, and an electric motor module equipped with the printed circuit board.The present invention also reduces the area occupied by the connector on the printed circuit board of an ECU, which requires a high degree of integration. [Means for solving the problem]

[0009] In order to solve the above problems, a connector is provided which is provided on a printed circuit board having a circuit and is formed from a conductive plate which electrically connects the circuit to a mating terminal, the connector comprising: a board mounting portion having a plurality of protrusions at one end which are inserted into holes provided in the printed circuit board; an erect portion which extends from a part of the other end of the board mounting portion away from the printed circuit board, bends midway, and extends towards the printed circuit board; a facing portion which extends from the end of the erect portion substantially parallel to the printed circuit board so as to face the board mounting portion; and a terminal portion which is connected to the end of the facing portion at its lower part and receives, clamps, and electrically connects a mating terminal from a direction perpendicular to the board surface of the printed circuit board. According to this, the board mounting portion receives, via the opposing portion and the upright portion, the force that may arise from misalignment in position or angle when the electric motor terminals are press-fitted into the terminal portion, making it easier for the position of the terminal portion to match the position of the electric motor terminal, and also dispersing stress to reduce the force applied to a specific point, thereby providing a connector that tolerates misalignment in position or angle of the connector on the printed circuit board relative to the electric motor terminals and reduces the risk of terminal deformation or damage to the electrical joint. Furthermore, by providing a three-dimensional upright portion as well as a surface-direction of the printed circuit board as a mechanism that can absorb stress, it is possible to reduce the area occupied by the connector on the printed circuit board of an ECU, which requires a high degree of integration.

[0010] Furthermore, the lower surface of the terminal portion may be in contact with the surface of the printed circuit board. With this, since the underside of the terminal portion abuts against the surface of the printed circuit board, displacement of the electric motor terminal in the direction of press-fitting into the terminal portion is minimized, further reducing the risk of deformation of the terminal or damage to the electrical connection.

[0011] Furthermore, the connecting portion between the facing portion and the standing portion may have a first notch at a corner on the side where the facing portion extends from the end of the standing portion. According to this, by providing a notch at the corner of the connection part with the standing part in the opposing part, the path for absorbing stress is lengthened, misalignment is tolerated, and the risk of deformation of the terminal or damage to the electrical joint can be further reduced.

[0012] Furthermore, the multiple protrusions provided at one end may be composed of a first protrusion provided on one side at a position farthest from the connection portion with the standing portion at the other end, a second protrusion provided on one side at a position closer than the first protrusion from the connection portion with the standing portion at the other end, and at least one third protrusion provided on the other side from the connection portion with the standing portion at the other end, and may be characterized by having a second notch portion at one corner of the connection portion between the board mounting portion and the standing portion. According to this, by providing a notch portion in the corner of the board mounting portion on the first protrusion side of the connection portion with the standing portion, the path for absorbing stress is lengthened, further reducing the risk of damage to the electrical connection portion of the first protrusion.

[0013] In order to solve the above problem, there is provided a printed circuit board that mounts the above connector, the printed circuit board having a first hole at a position corresponding to the first protrusion and the second protrusion, and a second hole at a position corresponding to the third protrusion, the first protrusion being inserted into the first hole and soldered thereto and connected to the circuit, the second protrusion being inserted into the first hole and soldered thereto but not connected to the circuit, and the third protrusion being inserted into the second hole and fitted thereto but not soldered thereto. This provides a printed circuit board that is configured to be less susceptible to stress on the first protrusion that is electrically connected to the circuit of the printed circuit board, thereby allowing for misalignment of the position and angle of the connector on the printed circuit board relative to the terminal of the electric motor, reducing the risk of deformation of the terminal or damage to the electrical joint.

[0014] In order to solve the above problem, an electric motor module is provided that includes an electric motor, the above-mentioned printed circuit board that receives electric power from the outside and supplies the power to the electric motor, a gear that outputs the power of the electric motor, and a storage section that stores the electric motor, the printed circuit board, and the gear, and the terminal section is electrically connected to the terminal of the electric motor. This provides an electric motor module that, by including the above-mentioned printed circuit board, allows for misalignment of the position and angle of the connector on the printed circuit board relative to the terminals of the electric motor, reducing the risk of deformation of the terminals and damage to the electrical joints. [Effects of the Invention]

[0015] As described above, the present invention provides a connector that allows for misalignment of the connector on a printed circuit board relative to the terminals of an electric motor, thereby reducing the risk of deformation of the terminals and damage to electrical connections, a printed circuit board on which the connector is mounted, and an electric motor module that includes the printed circuit board. Furthermore, the present invention reduces the area occupied by the connector on the printed circuit board of an ECU that requires a high degree of integration. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. <First Example> 1 to 6, an electric motor module 100, a connector 200 used in the electric motor module 100, and a printed circuit board 20 on which the connector 200 is mounted will be described. The electric motor module 100 is mounted on a vehicle and used to drive power windows, sliding doors, sunroofs, power seats, etc. The electric motor module 100 is modularized by integrating the electric motor 10 that drives these components, a gear 30 having a final output shaft 31, the printed circuit board 20, etc. into a single unit. When the electric motor module 100 is used to drive a power window, for example, it is attached to the inside of a door and raises and lowers the window glass via a window regulator.

[0018] The electric motor module 100 comprises an electric motor 10 as a drive source, a gear 30 that converts the axial direction of a final output shaft 31 to a direction perpendicular to the axial direction of a rotary shaft 11 of the electric motor 10, a printed circuit board 20 that mounts an external cable connector 23 for receiving electric power from the outside and electronic components 24 for driving the electric motor 10 from that power, and a storage section 40 and a connector storage section 50 that store these components. The gear 30 is stored inside the storage section 40 and is not shown in the drawings in this specification.

[0019] The electric motor 10 is a DC motor having a rotating shaft 11, and may be either brushed or brushless, without any particular limitation. A worm (not shown) is attached to the rotating shaft 11, driving a gear 30. The electric motor 10 has two plate-shaped electrodes 12 for receiving power from an external cable via a printed circuit board 20. The gear 30 has a worm wheel (not shown) that meshes with the worm, and a final output shaft 31 that is directly connected to the center of the worm wheel, and is rotatably housed in a housing 40. The worm wheel reduces the rotation speed of the rotating shaft 11 and transmits high torque to the final output shaft 31, which drives a regulator.

[0020] The storage section 40 stores the electric motor 10 and the gear 30 as a unit. The connector storage section 50 stores the printed circuit board 20 with the tip of the external cable connector 23 mounted on the printed circuit board 20 exposed to the outside so that it can be connected to an external cable (FIG. 1).

[0021] The printed circuit board 20 is equipped with an external cable connector 23 for receiving power from the outside, electronic components 24 for driving the electric motor 10 using that power, and two connectors 200 connected to the electrodes 12 for supplying driving power to the electric motor 10 (FIG. 2), and a circuit (not shown) electrically connecting these components is wired. The external cable connector 23 is configured to receive power from an external cable and to be connectable to an external cable for sending and receiving signals to and from the outside. The electronic components 24 are electrical components such as capacitors and semiconductors. The printed circuit board 20 is equipped with through holes 21 and non-through holes 22 for arranging the connectors 200 (FIG. 3), as will be described in detail below.

[0022] The connector 200 is formed by punching and bending a conductive plate that electrically connects the circuit provided on the printed circuit board 20 with the electrodes 12 of the electric motor 10, which serve as mating terminals. The connector 200 is generally made up of four parts: a board mounting portion 210, an upright portion 220, a facing portion 230, and a terminal portion 240 (FIG. 4).

[0023] When the connector 200 is attached to the printed circuit board 20, the board attachment portion 210 is attached with its flat surface approximately perpendicular to the printed circuit board 20. The board attachment portion 210 has four protrusions, namely a first protrusion 211, a second protrusion 212, and two third protrusions 213, on one end 21E1 of its flat surface that is closest to the printed circuit board 20, and these are inserted into holes provided in the printed circuit board 20 to be attached to the printed circuit board 20.

[0024] The standing portion 220 extends with the same width from a part near the center of the other end 21E2 of the flat surface of the board mounting portion 210 that is farther from the printed circuit board 20, in a direction substantially perpendicular to the printed circuit board 20, i.e., in a direction away from the printed circuit board 20. Furthermore, the standing portion 220 bends 180 degrees midway from the part that extends perpendicularly from the other end 21E2 of the board mounting portion 210, and extends with the same width in a direction approaching the printed circuit board 20 in a substantially perpendicular direction, to an end 22E1 that is at substantially the same position as the other end 21E2 of the board mounting portion 210 in a side view. The width of the standing portion 220 is smaller than the lengths of the board mounting portion 210 and the facing portion 230 in a plane parallel to the board surface of the printed circuit board 20.

[0025] The facing portion 230 extends from the end 22E1 of the standing portion 220 to both sides substantially parallel to the printed circuit board 20, facing the board mounting portion 210, without contacting the printed circuit board 20. The flat surface of the facing portion 230 is substantially perpendicular to the printed circuit board 20, similar to the flat surface of the board mounting portion 210. In this embodiment, the facing portion 230 extends to both sides from the end 22E1 of the standing portion 220, but may extend to only one side toward the terminal portion 240. In a plane parallel to the board surface of the printed circuit board 20, the facing portion 230 has a length that is slightly shorter than but substantially the same as that of the board mounting portion 210, and extends to an end 23E1 on one side toward the terminal portion 240, which is at substantially the same position as the first protrusion 211 in a top view or a side view.

[0026] The terminal portion 240 is composed of a clamping portion 241 formed in a tuning fork shape so as to sandwich the plate-shaped electrode 12 of the electric motor 10, and a base portion 242 formed below the clamping portion 241. The base portion 242 is connected to the end portion 23E1 of the facing portion 230 at the lower portion. The base portion 242 extends from the end portion 23E1 of the facing portion 230 in a direction perpendicular to the facing portion 230 and parallel to the printed circuit board 20. The flat surface of the base portion 242 is approximately perpendicular to the printed circuit board 20. The clamping portion 241 has the same flat surface as the base portion 242 and extends in a direction away from the printed circuit board 20. It receives, clamps, and electrically connects the electrode 12 of the electric motor 10 from a direction perpendicular to the board surface of the printed circuit board 20. The flat surface of the plate-shaped electrode 12 received by the clamping portion 241 is approximately parallel to the flat surfaces of the board mounting portion 210 and the facing portion 230.

[0027] When assembling a printed circuit board 20 having the connector 200 configured as described above with an electric motor 10, variations among the components can accumulate at the joint between the connector 200 and the electrode 12, causing positional or angular misalignment. Figure 6 shows how the connector 200 absorbs the stress caused by such misalignment to reduce the risk of damage to the electrical joint. As indicated by the arrows, if the flat electrode 12 is misaligned laterally relative to the terminal portion 240 (misalignment in a direction perpendicular to the flat surface of the board mounting portion 210 and the facing portion 230) or rotated (misalignment from the perpendicular to the flat surface of the terminal portion 240), the terminal portion 240 will move in response to the misalignment of the electrode 12, as indicated by the L-shaped dotted line. Accordingly, the facing portion 230, which is connected at the end 23E1, will also move.

[0028] Since the board mounting portion 210 is attached by inserting multiple protrusions into holes in the printed circuit board 20, it does not move, and therefore the upright portion 220 absorbs this movement. Because the facing portion 230 is supported by the end 22E1 of the upright portion 220, this movement of the terminal portion 240 and the facing portion 230 appears as a rotational movement approximately parallel to the board surface around the end 22E1. This occurs because there is a certain distance between the end 23E1 of the facing portion 230 and the end 22E1, which is the connection portion with the upright portion 220, and a moment is generated at the end 23E1. Because the width of the upright portion 220 is smaller than the length of the facing portion 230, this moment is mainly caused by twisting of the upright portion 220. The length from the end 22E1, which is the connection portion of the facing portion 230 with the upright portion 220, to the end 23E1, the width of the upright portion 220, and the total length from the connection portion with the board mounting portion 210 to the end 22E1 are determined appropriately based on the thickness and elasticity of the connector 200. Of course, since the connector 200 is formed from a conductive plate, not only the standing portion 220 but also the terminal portion 240, the opposing portion 230, and the board mounting portion 210 are slightly deformed and stressed.

[0029] In this way, the board mounting portion 210 receives, via the opposing portion 230 and the standing portion 220, force that may arise from misalignment in position or angle when the electrodes 12 of the electric motor 10 are press-fitted into the terminal portions 240. This makes it easier for the positions of the terminal portions 240 to match the positions of the electrodes 12 of the electric motor 10, and also distributes stress, reducing the force applied to a specific location. This provides a connector 200 that tolerates misalignment in position or angle of the connector 200 on the printed circuit board 20 relative to the electrodes 12 of the electric motor 10, reducing the risk of deformation of the connector 200 or damage to the electrical joint with the printed circuit board 20. Furthermore, by providing the standing portion 220 not only in the direction of the printed circuit board surface but also in a three-dimensional manner as a mechanism that can absorb stress, it is possible to reduce the area that the connector 200 occupies on the board surface of the printed circuit board of an ECU that requires a high degree of integration.

[0030] The board mounting portion 210 is provided with a first protrusion 211, a second protrusion 212, and two third protrusions 213 on one end 21E1 of the flat plate surface, each having a diameter approximately equal to the plate thickness that allows insertion into a hole in the printed circuit board 20. The first protrusion 211 and the second protrusion 212 are located on the side closer to the end 23E1 of the facing portion 230, i.e., closer to the terminal portion 240, from the connection portion with the standing portion 220, while the two third protrusions 213 are located on the opposite side, away from the terminal portion 240. The first protrusion 211 is located at a position farthest from the connection portion with the standing portion 220, i.e., almost at the end of the board mounting portion 210, and the second protrusion 212 is located closer to the connection portion with the standing portion 220 than the first protrusion 211, i.e., between the first protrusion 211 and the connection portion.

[0031] The first protrusion 211 and the second protrusion 212 are inserted into and soldered to through holes 21 at corresponding positions on the printed circuit board 20 (FIGS. 3 and 5). However, only the first protrusion 211 is electrically connected to the circuit provided on the printed circuit board 20; the second protrusion 212 is soldered to the through hole 21 and firmly fixed, but is not connected to the circuit. The third protrusion 213 is inserted into a non-through hole 22 at a corresponding position, fits loosely, and is not soldered. Note that although there are two third protrusions 213 in this embodiment, there may be only one.

[0032] The first protrusion 211 and the second protrusion 212 on one side of the connection portion between the board mounting portion 210 and the standing portion 220 are soldered to the through-hole 21 (21H in FIG. 6) and firmly fixed thereto. On the other hand, the third protrusion 213 on the other side, opposite the connection portion, is not soldered but is loosely fitted into the non-through-hole 22, and is able to move slightly when subjected to force from the connection portion with the standing portion 220. This allows the board mounting portion 210 to deform slightly between the second protrusion 212 and the third protrusion 213. In response to force from the connection portion with the standing portion 220, the greatest stress is generated between the connection portion and the second protrusion 212 in the board mounting portion 210. However, because the second protrusion 212 is firmly fixed but not connected to the circuit, even if the solder securing the second protrusion 212 to the through-hole 21 is damaged, the electrical connection between the connector 200 and the printed circuit board 20 is not affected. The joint portion between the first projection 211 and the through hole 21 is firmly fixed at a position farther away from the force received from the connection portion than the firmly fixed second projection 212, and therefore is less likely to be damaged.

[0033] In this way, by configuring the first protrusion 211, which is electrically connected to the circuit of the printed circuit board 20, to be less susceptible to stress, a printed circuit board 20 is provided which allows for misalignment of the position and angle of the connector 200 on the printed circuit board 20 relative to the electrode 12 of the electric motor 10, reducing the risk of deformation of the connector 200 and damage to the electrical joint.

[0034] In this embodiment, first protrusion 211 and second protrusion 212 are located on the side closer to terminal portion 240 from the connection portion with standing portion 220, and third protrusion 213 is located on the opposite side, but conversely, first protrusion and second protrusion may be located on the side opposite to terminal portion from the connection portion with standing portion, and third protrusion 213 may be located on the side closer to said connection portion. Even in this case, the first protrusion is located at the position farthest from the connection portion with standing portion, and the second protrusion is located between the first protrusion and said connection portion and is firmly fixed.

[0035] Furthermore, it is preferable that the board mounting portion 210 has a board mounting portion notch 214, which is a curved cutout, near the connection portion with the standing portion 220 and extending toward the first protrusion 211, i.e., at the corner of the connection portion on the first protrusion 211 side. By providing the notch 214 at the corner of the connection portion with the standing portion 220 in this manner, the path for absorbing stress to the first protrusion 211, which is electrically connected, is lengthened, allowing for misalignment and further reducing the risk of deformation of the connector 200 or damage to the electrical joint. Note that if the first and second protrusions are located on the opposite side of the connection portion with the standing portion from the terminal portion, the board mounting portion notch is formed in the opposite direction from the board mounting portion notch 214 of this embodiment, i.e., at the corner of the connection portion on the first protrusion side. This lengthens the path for absorbing stress to the first protrusion, which is electrically connected.

[0036] Furthermore, facing portion 230 preferably has facing portion notch 234, which is a curved cutout, in a portion that is near the connection portion with standing portion 220 and extends toward end 23E1, i.e., in a corner on the side extending from end 22E1. In this way, by providing notch 234 in facing portion 230 at the corner of the connection portion with standing portion 220, the path for absorbing stress is lengthened, misalignment is tolerated, and the risk of deformation of connector 200 and damage to the electrical joint can be further reduced.

[0037] Furthermore, it is preferable that the lower surface 24E1 of the base 242, which forms the lower surface of the terminal portion 240, abuts against the surface of the printed circuit board 20 when attached. By having the lower surface of the terminal portion 240 abut against the surface of the printed circuit board 20, displacement of the electrodes 12 of the electric motor 10 in the press-fit direction into the terminal portion 240 is minimized, and the risk of deformation of the connector 200 or damage to the electrical joint can be reduced.

[0038] As described above, the electric motor module 100 including the printed circuit board 20 mounted with the connector 200 can tolerate misalignment of the position and angle of the connector 200 on the printed circuit board 20 relative to the terminals (electrodes 12) of the electric motor 10, thereby reducing the risk of deformation of the connector 200 or damage to the electrical joints.

[0039] It should be noted that the present invention is not limited to the illustrated examples, and can be implemented in configurations that do not deviate from the scope of the claims. That is, although the present invention has been particularly shown and described primarily with reference to specific embodiments, those skilled in the art can make various modifications to the above-described embodiments in terms of the number and other details without departing from the scope of the technical idea and purpose of the present invention.
