FIG. 1 is an external perspective view of an oil pump device according to the present embodiment. FIG. 3 is an exploded perspective view of the connector unit. They are a front view, a rear view, a top view, a side view, and a bottom view of the terminal connector. FIG. 3 is a front view, a top view, a side view, and a bottom view of the connector subunit. It is a perspective view of a connector unit. FIG. 3 is a perspective view of the main parts around the cylinder body.

Hereinafter, an oil pump device 1 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of an oil pump device 1 according to the present embodiment.

The oil pump device 1 according to the present embodiment supplies oil (for example, lubricating oil) to an engine clutch or a transmission mechanism clutch mounted on, for example, an automobile. However, the use of the oil pump device 1 is not limited to this. As shown in FIG. 1, the oil pump device 1 is a so-called "electric oil pump" including a motor device 2 and an oil pump 3.

The motor device 2 generates driving force for rotating the oil pump 3. The oil pump 3 compresses and sends out oil by being rotated by the driving force of the motor device 2 (hereinafter referred to as "pressure feeding"). Since the configuration of the oil pump 3 is already well known, detailed explanation will be omitted.

The motor device 2 includes an electric motor 4, a control circuit 5 that controls the operation of the electric motor 4, and a connector unit 6 that connects the control circuit 5 to an external device (for example, a power source) not shown. It is an integrated type motor. The electric motor 4 is, for example, a brushless motor. Since the configurations of the electric motor 4 and the control circuit 5 are already well known, detailed explanation will be omitted.

FIG. 2 is an exploded perspective view of the connector unit 6. As shown in FIG. 2, the connector unit 6 mainly includes a terminal connector 10, an inner mold body 20, and an outer mold body 30. The terminal connector 10 is an electrically conductive member through which drive current and control signals flow. The inner mold body 20 is an insulating material that covers (moldes) the terminal connector 10. Hereinafter, a component obtained by molding the terminal connector 10 with the inner mold body 20 will be referred to as a "connector subunit 10 & 20." The outer mold body 30 is an insulating material that further covers (moldes) the connector subunits 10 & 20.

FIG. 3 is a front view (left view), rear view (right view), top view (top view), side view (middle view), and bottom view (bottom view) of the terminal connector 10. As shown in FIGS. 2 and 3, the terminal connector 10 includes a pair of power lines 11a, 11b and a pair of signal lines 12a, 12b. A drive current for driving the electric motor 4 flows through the pair of power supply lines 11a and 11b. A control signal for controlling the control circuit 5 flows through the pair of signal lines 12a and 12b.

The pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b extend approximately in the front-rear direction while being bent in the middle. Further, the pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are divided into a first terminal part 13, a second terminal part 14, a parallel part 15, and a bent part 16 in the front-rear direction. In addition, in this specification, the left-right direction will be described as a first direction, the front-back direction as a second direction, and the up-down direction as a third direction. However, the first direction, the second direction, and the third direction are relative, and are not limited to the above example (that is, they do not limit the installation direction of the oil pump device 1).

The first terminal portion 13 is one end (the end on the back side) of the terminal connector 10 and is connected to the control circuit 5 . The pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are arranged (layout) at a predetermined interval in the left-right direction in the first terminal portion 13. The layout of the first terminal section 13 is changed as appropriate by the control circuit 5.

The second terminal portion 14 is the other end (the end on the front side) of the terminal connector 10 and is connected to an external device. The pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are arranged (layout) apart from each other in the left-right direction and the front-rear direction in the second terminal portion 14. More specifically, the pair of power supply lines 11a and 11b are arranged above the pair of signal lines 12a and 12b at a predetermined interval in the left-right direction. Further, the pair of signal lines 12a and 12b are arranged below the pair of power supply lines 11a and 11b at a predetermined interval in the left-right direction. The layout of the second terminal section 14 is changed as appropriate depending on the interface of the external device. That is, the second terminal section 14 may have any layout as long as it is different from the first terminal section 13.

The parallel portion 15 is located between the first terminal portion 13 and the bent portion 16 in the front-rear direction (that is, at a position adjacent to the first terminal portion 13). The pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b extend in parallel in the front-rear direction at a predetermined interval in the left-right direction in the parallel portion 15.

The bent portion 16 is located between the second terminal portion 14 and the parallel portion 15 in the front-rear direction. The pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are bent at the bending part 16 so as to change the layout of the first terminal part 13 and the second terminal part 14. Further, the pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are bent at the bent portion 16 so as not to contact (short circuit) each other (that is, at a predetermined interval). That is, how the pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are bent at the bending part 16 varies as appropriate depending on the layout of the first terminal part 13 and the second terminal part 14.

However, the pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are bent at the bending part 16 within the range of the parallel part 15 in the left-right direction. In other words, the pair of power lines 11a, 11b and the pair of signal lines 12a, 12b do not protrude from the width of the parallel portion 15 in the left-right direction at the bent portion 16. In other words, the maximum width of the terminal connector 10 in the left-right direction matches the width of the parallel portion 15.

Further, convex portions 17a and 18a are formed on the power line 11a and the signal line 12a in the parallel portion 15 at positions facing each other. The convex portions 17a and 18a protrude toward each other. The power line 11a and the signal line 12a are integrally formed by press working. Therefore, the power line 11a and the signal line 12a are connected by bridges (not shown) formed at the positions of the protrusions 17a and 18a. Then, as will be described later, after the terminal connector 10 is molded with the inner mold body 20, the bridge is removed (that is, the power line 11a and the signal line 12a are cut). That is, the protrusions 17a and 18a are traces of cutting the bridge (ends of the bridge). Similarly, convex portions 17b and 18b are formed on the power line 11b and the signal line 12b in the parallel portion 15.

Furthermore, when the bending portion 16 is viewed from above and below, the pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are arranged so as not to overlap with each other ( That is, it includes non-overlapping portions (disposed shifted in the left-right direction and front-back direction). Note that in the overlapping portion, the power line 11a and the signal line 12a are located below the power line 11b and the signal line 12b. Note that the pair of power supply lines 11a, 11b and the pair of signal lines 12a, 12b are arranged at a predetermined interval in the vertical direction even in the overlapping portion. That is, the pair of power lines 11a, 11b and the pair of signal lines 12a, 12b are not in contact throughout the entire area of the terminal connector 10.

FIG. 4 is a front view (left view), a top view (top view), a side view (middle view), and a bottom view (bottom view) of the connector subunits 10 & 20. In addition, in FIG. 4, the terminal connector 10 is shown shaded. The connector subunits 10 & 20 are injection molded by inserting the terminal connector 10 into a mold that can be opened and closed in the vertical direction, and filling the mold with a resin material. Thereby, the terminal connector 10 is molded with the inner mold body 20, and the connector subunits 10 & 20 are formed.

As shown in FIG. 4, the first terminal portion 13 and the second terminal portion 14 of the terminal connector 10 are exposed from the inner mold body 20. Further, as shown in FIGS. 2 and 4, the inner mold body 20 includes a plurality of first openings 21a, 21b, 21c, 21d, 21e, 21f, 21g, and 21h, a plurality of protrusions 22a, 22b, and a plurality of second openings 23a, 23b, 23c, and 23d, a flange portion 24, and a plurality of positioning portions 25a and 25b are formed.

The first openings 21a to 21d extend downward from the upper surface (outer peripheral surface) of the inner mold body 20 toward the terminal connector 10. Further, the first openings 21a to 21d are formed facing the bent portion 16 of the terminal connector 10 in the vertical direction. More specifically, the first openings 21a to 21d are formed facing the non-overlapping portions of the power supply line 11a and the signal line 12a in the vertical direction.

The first openings 21e to 21h extend upward from the lower surface (outer peripheral surface) of the inner mold body 20 toward the terminal connector 10. Further, the first openings 21e to 21h are formed facing the bent portion 16 of the terminal connector 10 in the vertical direction. More specifically, the first openings 21e to 21h are formed facing the non-overlapping portions of the power supply line 11b and the signal line 12b in the vertical direction.

When injection molding the connector subunits 10 & 20, pins (not shown) are placed at positions corresponding to the first openings 21a to 21h. As shown by dot hatching in FIG. 3, the pins arranged at the positions corresponding to the first openings 21a to 21d abut on the power line 11a and the signal line 12a from above, and restricts the upward movement of Further, the pins arranged at positions corresponding to the first openings 21e to 21h abut the power line 11b and the signal line 12b from below to restrict the downward movement of the power line 11b and the signal line 12b. Then, by removing the pins after injection molding, the first openings 21a to 21h are formed. This can prevent the power lines 11a, 11b and the signal lines 12a, 12b from moving (contacting) due to the pressure of the resin material filled into the mold.

That is, the first openings 21a to 21d connect the power lines 11a and 11a, which are located on one side (that is, the upper side) in the first direction of the inner mold body 20 and on the other side (that is, the lower side) in the third direction in the overlapping portion. It is arranged facing the signal line 12a. The first openings 21e to 21h are located on the other side (that is, the lower side) in the first direction of the inner mold body 20, and the power line 11b and the signal line that are located on one side (that is, the upper side) in the third direction in the overlapping part. 12b.

As shown by diagonal hatching in FIG. 3, the protrusions 22a and 22b extend downward from the upper surface (outer peripheral surface) of the inner mold body 20 toward the bent portion 16 of the terminal connector 10. The protrusion 22a contacts the power line 11a from the rear side (second direction) and the signal line 12b from the right side (third direction). Further, the protrusion 22b contacts the power supply line 11b from the left side (third direction), and contacts the signal line 12a from the front side (second direction).

When injection molding the connector subunits 10 & 20, pins (not shown) are placed at positions corresponding to the protrusions 22a, 22b. Thereby, the positions of the power supply lines 11a, 11b and the signal lines 12a, 12b in the left-right direction and the front-rear direction are restricted. Further, the pins arranged at positions corresponding to the protrusions 22a and 22b are arranged at a predetermined interval between the power lines 11a and 11b and the signal lines 12a and 12b. As a result, when the mold is filled with the resin material, the resin material also enters between the power lines 11a, 11b and the signal lines 12a, 12b and the pins. As a result, protrusions 22a and 22b are formed.

That is, the protrusions 22a, 22b extend in the third direction toward the bent portion 16 of the terminal connector 10, and extend in the first direction or the second direction to at least one of the power supply lines 11a, 11b and the signal lines 12a, 12b. contact from.

The second openings 23a, 23b extend downward from the upper surface (outer peripheral surface) of the inner mold body 20 toward the terminal connector 10. Further, the second openings 23c and 23d extend upward from the lower surface (outer peripheral surface) of the inner mold body 20 toward the terminal connector 10. The second openings 23a to 23d are formed facing the parallel portion 15 of the terminal connector 10 in the vertical direction. More specifically, the second openings 23a to 23d are formed at positions facing the convex portions 17a, 17b, 18a, 18b of the power supply lines 11a, 11b and the signal lines 12a, 12b in the vertical direction.

When injection molding the connector subunits 10 & 20, a part of the mold is placed at a position corresponding to the second openings 23a to 23d. Part of this mold contacts the power lines 11a, 11b and the signal lines 12a, 12b in the upward and left-right directions. This restricts the vertical and horizontal positions of the power supply lines 11a, 11b and the signal lines 12a, 12b in the parallel portion 15. Then, when the connector subunits 10 & 20 are removed from the mold, second openings 23a to 23d are formed. Further, by removing the bridge through the second openings 23a to 23d, convex portions 17a, 17b, 18a, and 18b are formed on the terminal connector 10.

The flange portion 24 is a portion that protrudes radially outward from a substantially central portion of the inner mold body 20 in the front-rear direction and continues in the circumferential direction. The flange portion 24 regulates the position of the connector subunits 10 & 20 in the front-rear direction when molded with the outer mold body 30, and also prevents the outer mold body 30 from having an extremely thick portion (that is, the thickness is uneven). The role is to prevent the occurrence of

The positioning parts 25a and 25b are provided on the front side of the inner mold body 20 (more specifically, in front of the flange part 24). Further, the positioning portions 25a and 25b protrude radially outward from the outer peripheral surface of the inner mold body 20. In this embodiment, the positioning portion 25a protrudes rightward from the lower right corner of the inner mold body 20 and extends in the front-rear direction. Further, the positioning portion 25b protrudes leftward from the upper left corner of the inner mold body 20 and extends in the front-rear direction. The positioning parts 25a and 25b play a role in preventing the connector subunits 10 & 20 from rotating within the mold when the connector unit 6 is molded as described later.

FIG. 5 is a perspective view of the connector unit 6. The connector unit 6 is injection molded by inserting the connector subunits 10 & 20 into a mold that can be opened and closed in the left-right direction, and then filling the mold with a resin material. Thereby, the connector subunits 10 & 20 are molded with the outer mold body 30, and the connector unit 6 is formed. As shown in FIGS. 2 and 5, the connector unit 6 mainly includes a circuit connection section 31 and an external connection section 32.

The circuit connection section 31 is an interface that connects the first terminal section 13 to the control circuit 5. The circuit connection portion 31 exposes the first terminal portion 13 to the outside (back side) of the connector unit 6. Then, by fixing the circuit connection portion 31 to the case of the control circuit 5 with bolts or the like, the first terminal portions 13 of the power lines 11a, 11b and the signal lines 12a, 12b are electrically connected to the control circuit 5.

The external connection section 32 is an interface that connects the second terminal section 14 to an external device. The external connection portion 32 includes a cylindrical body 33 . The cylindrical body 33 has a cylindrical outer shape that protrudes forward (in the second direction) so as to surround the inner mold body 20 . Further, the protruding end (front end) of the cylinder 33 is open. Further, the external connection portion 32 (cylindrical body 33) exposes the second terminal portion 14 to the outside (front surface) of the connector unit 6. Then, by inserting the external connection portion 32 (cylindrical body 33) into the interface of the external device, the second terminal portions 14 of the power lines 11a, 11b and the signal lines 12a, 12b are electrically connected to the external device. .

FIG. 6 is a perspective view of the main parts around the cylinder 33. In addition, in FIG. 6, the inner mold body 20 is shown shaded. As shown in FIG. 6, the outer mold body 30 has recesses 34a and 34b formed therein. The recesses 34a and 34b are formed inside the cylinder 33 and outside the inner mold body 20. More specifically, the recesses 34a and 34b are formed adjacent to the inner mold body 20 in the left-right direction. Further, the recesses 34a and 34b are recessed rearward (in the second direction) from the front surface of the outer mold body 30.

Further, a portion of the side surfaces of the recesses 34a and 34b are cut out. As a result, a portion of the inner mold body 20 is exposed inside the recesses 34a, 34b through the cutout side surfaces of the recesses 34a, 34b. More specifically, as shown in FIG. 6(A), the upper surface of the positioning portion 25a and the right side surface of the inner mold body 20 connected thereto are exposed inside the recess 34a. Further, as shown in FIG. 6(B), the lower surface of the positioning portion 25b and the left side surface of the inner mold body 20 connected thereto are exposed inside the recessed portion 34b.

When injection molding the connector unit 6, a part of the mold is placed at a position corresponding to the recesses 34a and 34b. A part of this mold contacts the positioning parts 25a, 25b and the side surface of the inner mold body 20 in the upward and left-right directions. This can prevent the connector subunits 10 & 20 from rotating due to the pressure of the resin material filled into the mold. Further, the resin material does not enter the contact surface between the connector subunits 10 & 20 and the mold. As a result, when the connector unit 6 is removed from the mold, the portion of the inner mold body 20 that was in contact with the mold is exposed inside the recesses 34a and 34b.

According to the above embodiment, for example, the following effects are achieved.

According to the above embodiment, at the bending portion 16 of the terminal connector 10, the power wires 11a, 11b and the signal wires 12a, 12b are bent within the range of the parallel portion 15 in the left-right direction. It is possible to downsize in this direction. As a result, a motor device 2 and an oil pump device 1 equipped with a small-sized connector unit 6 can be obtained.

Further, according to the above embodiment, when injection molding the connector subunits 10 & 20, by arranging pins at positions corresponding to the first openings 21a to 21h, the power lines 11a, 11b and the signal lines 12a, 12b are The vertical position of is regulated. Thereby, even if the intervals between the power lines 11a, 11b and the signal lines 12a, 12b are set small, short circuits can be prevented, so the connector unit 6 can be downsized.

Further, according to the embodiment described above, by providing the inner mold body 20 with the protrusions 22a and 22b that contact at least one of the power supply lines 11a and 11b and the signal lines 12a and 12b from the left and right directions or the front and rear directions, the power supply The positions of the lines 11a, 11b and the signal lines 12a, 12b in the left-right direction and the front-back direction are regulated. Thereby, even if the intervals between the power lines 11a, 11b and the signal lines 12a, 12b are set small, short circuits can be prevented, so the connector unit 6 can be downsized.

Further, according to the above embodiment, when injection molding the connector subunits 10 & 20, by arranging a part of the mold at a position corresponding to the second openings 23a to 23d, the power lines 11a, 11b and the signal The vertical and horizontal positions of the lines 12a and 12b are regulated. Thereby, even if the intervals between the power lines 11a, 11b and the signal lines 12a, 12b are set small, short circuits can be prevented, so the connector unit 6 can be downsized.

Further, according to the above embodiment, the terminal connector 10 is molded into the inner mold body by providing the second openings 23a to 23b at positions facing the bridge connecting the adjacent power lines 11a, 11b and the signal lines 12a, 12b. After molding at 20, the bridge can be cut. As a result, the positional accuracy of the power lines 11a, 11b and the signal lines 12a, 12b can be easily improved.

Further, according to the above embodiment, when injection molding the connector unit 6, by arranging a part of the mold at a position corresponding to the recesses 34a and 34b, the connector subunits 10 & 20 are formed in the connector unit 6. It can prevent rotation. By downsizing the terminal connector 10 in the left-right direction, the positioning portions 25a and 25b formed on the outer peripheral surface of the inner mold body 20 can be housed inside the cylindrical body 33. As a result, the connector unit 6 can be downsized.

As in the above embodiment, by downsizing the connector unit 6, the amount of resin in the inner mold body 20 and the outer mold body 30 can be reduced. Further, by employing the various positioning methods described above, it is expected that the number of defective products will be reduced. These will contribute to ensuring sustainable production and consumption patterns in the SDGs.
