Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
A first embodiment of the present invention is shown in FIGS. The wiring restricting device 1 of the present embodiment restricts the wiring 2 used in the automatic transmission, and is used in a state immersed in oil used in the automatic transmission. The oil of the present embodiment corresponds to the “working fluid” described in the claims. In FIGS. 3 and 4, the wiring 2 is indicated by a broken line in order to make the drawings easy to see.

The wiring restriction device 1 includes a metal plate 10, a resin member 20, a hydraulic switch 30 as a hydraulic pressure switch, a connection portion 40, a restriction means 50, and the like.
As shown in FIGS. 1 and 2, the metal plate 10 is made of a plate-like metal and has rigidity capable of maintaining the shape of the metal plate itself against a pressing force acting from a hydraulic switch 30 described later. .
The metal plate 10 has a hole 11 that communicates in the thickness direction. The hole 11 has a small diameter hole 12 located on the resin member side and a large diameter hole 13 located on the side opposite to the resin member from the small diameter hole 12. The large-diameter hole 13 has a tapered shape in which the inner diameter on the side opposite to the resin member is larger than the inner diameter on the resin member side.

As shown in FIG. 2, the resin member 20 is a reinforced resin including, for example, glass fiber, and is provided on one end surface of the metal plate 10 in the plate thickness direction.
The resin member 20 is provided with two hydraulic switches 30. Since the two hydraulic switches 30 have substantially the same configuration, only one hydraulic switch 30 will be described here.

The hydraulic switch 30 includes a hydraulic switch main body 300, a movable disk 31, a power supply side terminal 32, a ground side terminal 33, and the like.
The hydraulic switch body 300 has a cylindrical hole 21 at the center.
The movable disk 31 has a peripheral portion held by the power supply side terminal 32 and a central portion exposed in the cylindrical hole 21. The movable disk 31 is operated by the hydraulic pressure supplied to the cylindrical hole 21.
The power supply side terminal 32 is fixed to the insert terminal 22 of the resin member 20 with a separate member 23. The ground side terminal 33 is fixed to the metal plate 10 with a separate member 24. Examples of the separate members 23 and 24 include rivets.

When the hydraulic pressure supplied to the cylindrical hole 21 of the hydraulic switch 30 is lower than the predetermined pressure set in the hydraulic switch 30, the movable disk 31 is in the position indicated by the solid line A. When the hydraulic pressure supplied to the cylindrical hole 21 becomes higher than a predetermined pressure, the movable disk 31 moves to the position indicated by the broken line B and contacts the ground side terminal 33. As a result, the power supply side terminal 32 is electrically connected to the ground side terminal 33 through the movable disk 31. That is, it can be said that the hydraulic switch 30 detects the oil state of the automatic transmission.
The O-ring 34 provided on the side opposite to the metal plate of the cylindrical hole 21 prevents oil leakage with a valve body of an automatic transmission (not shown) to which the wiring restriction device 1 is attached.

  As shown in FIG. 4, the connecting portion 40 extends from the resin member 20 to the inside of the hole 11 of the metal plate 10 and fills the small diameter hole 12 and the large diameter hole 13. That is, the connecting portion 40 has a shape corresponding to the small diameter hole 12 and the large diameter hole 13 of the metal plate 10 and fixes the resin member 20 and the metal plate 10. Thereby, the distance between the power supply side terminal 32 fixed to the insert terminal 22 of the resin member 20 and the ground side terminal 33 fixed to the metal plate 10 is kept constant. Therefore, the hydraulic switch 30 can be accurately operated by the hydraulic pressure supplied to the cylindrical hole 21.

The restricting means 50 protrudes from the connecting portion 40 to the side opposite to the resin member and restricts the route of the wiring 2. The wiring restriction device 1 includes two restriction means 50. Since the configuration of the two regulating means 50 is substantially the same, here, the configuration of only one regulating means will be described. In addition, there is no restriction | limiting in the number of the control means 50 with which the wiring control apparatus 1 is provided, For example, the control means 50 is good also as one piece or two or more.
The restricting means 50 includes a first snap fit portion 501 composed of a first arm portion 51 and a first claw portion 511, and a second snap fit portion 502 composed of a second arm portion 52 and a second claw portion 522. . The restricting means 50 has an accommodation space 53 between the first snap fit portion 501 and the second snap fit portion 502. The accommodation space 53 is set to a size corresponding to the outer diameter of the wiring 2 and can suppress vibration of the wiring 2.

  The first arm portion 51 and the second arm portion 52 extend from the connection portion 40 to the side opposite to the resin member. The first arm portion 51 and the second arm portion 52 are provided facing each other in the vertical direction with respect to the direction in which the wiring 2 passes. The end surface 43 on the anti-resin member side of the connecting portion 40 located between the first arm portion 51 and the second arm portion 52 is flush with the end surface 44 on the anti-resin member side of the connecting portion 40 excluding the end surface 43. Is located. Therefore, the wiring 2 regulated by the regulation means 50 is arranged on the same plane as the metal plate 10.

The first claw portion 511 extends from the first arm portion 51 toward the second arm portion 52. The 1st nail | claw part 511 has the 1st inclined surface 54 which goes to the 2nd arm part 52 from the upper end of the 1st arm part 51, and inclines to the metal plate side.
The second claw portion 522 extends from the upper end portion of the second arm portion 52 toward the first arm portion 51. The 2nd nail | claw part 522 has the 2nd inclined surface 55 which goes to the 1st arm part 51 from the upper end of the 2nd arm part 52, and inclines to the metal plate side.
When the wiring 2 is assembled into the accommodation space 53 along the first inclined surface 54 and the second inclined surface 55, the first arm portion 51 and the second arm portion 52 are elastically deformed in a direction away from each other. When the wiring 2 is assembled in the accommodation space 53, the first arm portion 51 and the second arm portion 52 return to their original positions. At this time, the first claw portion 511 and the second claw portion 522 prevent the wiring 2 from coming out of the accommodation space 53. Thereby, the wiring 2 is reliably held by the restricting means 50.

The connecting portion 40 and the resin member 20 have a first through hole 41 and a second through hole 42 that extend from the accommodation space 53 to the end surface of the resin member 20 on the side opposite to the metal plate. The first through hole 41 is formed at a position facing the first claw part 511, and the second through hole 42 is formed at a position facing the second claw part 522.
In general, the oil of an automatic transmission in which the wiring restriction device 1 is installed contains various foreign matters caused by wear of metal parts. The first through hole 41 and the second through hole 42 can discharge foreign substances from the accommodation space 53 to the side opposite to the metal plate of the resin member 20. Therefore, foreign matter contained in the oil is prevented from accumulating in the accommodation space 53.
Moreover, the oil of the automatic transmission in which the wiring control apparatus 1 is installed is used in the range of −40 to + 150 ° C., for example. The metal plate 10 and the resin member 20 have different linear expansion coefficients. Therefore, when the metal plate 10 and the resin member 20 expand or contract due to a change in oil temperature, the stress acting on the resin member 20 from the metal plate 10 is absorbed by the first through hole 41 and the second through hole 42. .

The shapes of the first through hole 41, the second through hole 42, the first claw portion 511, and the second claw portion 522 can be arbitrarily set. In the present embodiment, as shown in FIG. 3, when viewed from the thickness direction of the metal plate 10, the first through hole 41 and the second through hole 42 are square, and the first claw portion 511 and the second claw portion. 522 is also visually recognized as a square.
Here, when the horizontal direction in the drawing of FIG. 3 is horizontal and the vertical direction of the drawing is vertical, the horizontal length of the first through hole 41 is X, and the vertical length is Y. The horizontal length of the 1st nail | claw part 511 is set to X ', and the vertical length is set to Y'. Further, the distance between the first through hole 41 and the second through hole 42 is Z, and the distance between the first claw part 511 and the second claw part 522 is Z ′.
At this time, there is a relationship of X ≧ X ′, Y ≧ Y ′, and Z ≦ Z ′.

That is, when the first through hole 41 and the first claw portion 511 are projected onto a virtual plane α (see FIG. 4) perpendicular to the thickness direction of the metal plate 10, the projection surface of the first claw portion 511 is the first. It is located inside the projection surface of the through hole 41 or overlaps the projection surface of the first through hole 41. Further, when the second through hole 42 and the second claw portion 522 are projected with respect to the virtual plane α, the projection surface of the second claw portion 522 is located inside the projection surface of the second through hole 42, or It overlaps with the projection surface of the second through hole 42.
Thereby, when the wiring control apparatus 1 is injection-molded, the mold structure and the manufacturing process can be simplified as described below.

FIG. 5 is a schematic view of a mold used when the wire regulating device 1 is injection molded. The mold is composed of an upper mold 60 and a lower mold 70. The upper mold 60 and the lower mold 70 of the present embodiment correspond to “a metal mold covered from one side in the thickness direction of the metal plate” and “a metal mold covered from the other” described in the claims.
The lower mold 70 includes a lower mold main body 73 that forms the lower end surface of the resin member 20, a first pin 71 that extends from the lower mold main body 73 toward the upper mold side and forms the first through hole 41, and a second through hole. And a second pin 72 that forms the plate 42. The first pin 71 and the second pin 72 form a surface on which the first arm portion 51 and the second arm portion 52 face each other, and a surface on the metal plate side of the first claw portion 511 and the second claw portion 522.

The upper die 60 includes an upper die body 63, a first cavity 61 that forms the first arm portion 51 and the first claw portion 511, and a second cavity 62 that forms the second arm portion 52 and the second claw portion 522. Have The upper mold 60 includes an upper mold pin 64 between the first cavity 61 and the second cavity 62. The upper mold pin 64 is inserted between the first pin 71 and the second pin 72. The surface 641 on the lower mold main body side of the upper mold pin 64 forms an end surface 43 on the side opposite to the resin member of the connection portion 40 located between the first arm portion 51 and the second arm portion 52. The lower mold body side surface 641 of the upper mold pin 64 is located on the same plane as the metal plate side surface 631 of the upper mold body 63. Therefore, the configuration of the upper mold 60 is simplified.
In the state where the metal plate 10 and the component parts of the insert terminal 22 are installed between the upper mold 60 and the lower mold 70, the molten resin is injected from an injection port (not shown). Thereby, the resin member 20, the connecting portion 40, and the restricting means 50 obtained by molding the metal plate 10 and the component parts of the insert terminal 22 are integrally formed.

The wiring restriction device 1 of the first embodiment has the following operational effects.
(1) In the first embodiment, the restricting means 50 projecting from the connecting portion 40 extending from the resin member 20 to the inside of the hole of the metal plate 10 toward the anti-resin member restricts the path of the wiring 2.
Thereby, it becomes possible to reduce the number of parts of the wiring control apparatus 1 by integrally forming the resin member 20, the connection part 40, and the control means 50. Therefore, it is possible to eliminate the step of separately attaching the member that regulates the wiring 2 to the metal plate 10. Therefore, while simplifying the structure of the wiring control apparatus 1, the assembly man-hour of the wiring 2 can be reduced.

(2) In the first embodiment, the restricting means 50 includes a first arm portion 51, a second arm portion 52, and an accommodation space 53.
As a result, the wiring 2 can be easily assembled into the accommodation space 53 from between the first arm portion 51 and the second arm portion 52. The route of the wiring 2 housed in the housing space 53 is regulated by the first arm portion 51 and the second arm portion 52.

(3) In the first embodiment, the restricting means 50 has the first claw portion 511 or the second claw portion 522.
Thus, the first claw portion 511 and the second claw portion 522 prevent the wiring 2 accommodated in the accommodation space 53 from coming out of the accommodation space 53. Therefore, the restricting means 50 can reliably hold the wiring 2.
The restricting means 50 may have only one of the first claw portion 511 or the second claw portion 522. Even in that case, the regulating means 50 can hold the wiring 2.

(4) In 1st Embodiment, the connection part 40 and the resin member 20 have the 1st through-hole 41 and the 2nd through-hole 42 which are extended from the storage space 53 to the end surface by the side of the anti-metal plate of the resin member 20. As shown in FIG.
As a result, the foreign matter that has entered the accommodation space 53 of the restricting means 50 passes through the first through hole 41 or the second through hole 42, so that the foreign matter is prevented from accumulating in the accommodation space 53. Therefore, even when the covering of the wiring 2 is damaged and the conductor portion is exposed, a short circuit with a foreign object can be prevented.
Further, when the metal plate 10 and the resin member 20 expand or contract due to a temperature change of the wiring regulating device 1, stress acting on the resin member 20 from the metal plate 10 due to a difference in linear expansion coefficient is applied to the first through hole 41 and the first through hole 41. It can be reduced by the two through holes 42.

(5) In 1st Embodiment, when the 1st through-hole 41 and the 1st nail | claw part 511 are projected with respect to the virtual plane (alpha) perpendicular | vertical to the plate | board thickness direction of the metal plate 10, the projection surface of the 1st nail | claw part 511 is It is located inside the projection surface of the first through hole 41 or overlaps the projection surface of the first through hole 41. The relationship between the 2nd through-hole 42 and the 2nd nail | claw part 522 is also the same.
Thereby, when the wiring restricting device 1 is injection-molded, the restricting means 50 can be formed by two molds composed of the upper die 60 and the lower die 70. Therefore, the mold structure and manufacturing process can be simplified by reducing the number of molds.

(6) In the first embodiment, the end surface 43 on the anti-resin member side of the connecting portion 40 located between the first arm portion 51 and the second arm portion 52 is the anti-resin of the connecting portion 40 excluding the end surface 43. It is located on the same plane as the end surface 44 on the member side.
This makes it possible to align the surfaces 631 and 641 on the metal plate side of the upper mold 60 on the same plane when the wiring restricting device 1 is injection-molded. Therefore, the mold structure can be simplified.

(7) In 1st Embodiment, the connection part 40 is filling the small diameter hole 12 and the large diameter hole 13 which the metal plate 10 has.
Thereby, the connection part 40 can fix the resin member 20 and the metal plate 10 reliably.

(8) In 1st Embodiment, the metal plate 10 has the rigidity which can maintain the shape of metal plate itself with respect to the pressing force which acts via the hydraulic switch 30 from the oil of an automatic transmission.
Thereby, the hydraulic switch 30 can ensure sealing performance and can reliably detect the hydraulic pressure.

In the second embodiment, the first cylindrical portion 81 and the second cylindrical portion 82 both have a shape protruding from the connecting portion 40 in a columnar shape, and thus the configuration of the restricting means can be simplified.

As shown in FIG. 7, in the second embodiment, a liquid temperature sensor 35 is provided inside the cylindrical hole 211 provided in the resin member 20 instead of the hydraulic switch of the first embodiment.
The liquid temperature sensor 35 includes a thermistor 36 and a mold body 37 that resin-molds the thermistor 36. The thermistor 36 changes its resistance according to the temperature of the oil supplied to the cylindrical hole 211, and changes the voltage flowing from the power supply side terminal 32 to the ground side terminal 33. The power supply side terminal 32 and the ground side terminal 33 are molded in the resin member 20.

  The oil temperature supplied to the cylindrical hole 211 acts on the liquid temperature sensor 35. The metal plate 10 has a rigidity capable of maintaining the shape of the metal plate itself against the pressing force acting from the oil via the mold body 37 of the liquid temperature sensor 35. Therefore, disconnection of the lead wires 38 and 39 of the thermistor 36 is prevented, and the liquid temperature sensor 35 can accurately detect the temperature of the oil.
