  In the connector attachment structure of Patent Document 1, a bracket is attached to a main body of an automatic transmission of a car, and the connector is disposed in an arrangement hole of a case covering the main body of the automatic transmission. The connector is then exposed to the oil used in the automatic transmission. Therefore, the material constituting the connector is required to be excellent not only in heat resistance but also in oil resistance.

  However, a material excellent in heat resistance and oil resistance contains, for example, glass fibers and the like, and is less likely to be elastically deformed. In particular, since the locking piece provided on the connector is not easily elastically deformed, the locking operation of the locking piece to the mounting piece of the bracket becomes difficult. In addition, when the locking piece is forcibly deformed elastically, the locking piece may be damaged.

  The present invention has been made in view of such problems, and has been obtained as an attempt to provide a connector support that can facilitate the engaging operation between a bracket and a connector.

The Young's modulus of the second material is on the connector support, which is smaller than the Young's modulus of the first material.

  In the connector support, the connector is constituted by the connector resin portion made of the first material and the arm resin portion made of the second material, and the Young's modulus of the second material is made the Young of the first material It is smaller than the rate. Then, by reducing the Young's modulus of the second material, the engaging arm portion formed on the arm resin portion can be easily elastically deformed. In addition, since the engaging arm portion is easily elastically deformed, the engaging operation of the engaging arm portion of the connector with the engaging piece of the bracket can be facilitated, and the engaging arm portion is protected from breakage.

Embodiment
As shown in FIG. 1, the connector support 1 of this embodiment includes the connector 3 and a bracket 2 to which the connector 3 is attached and which supports the connector 3 so as to be movable. The bracket 2 has a base portion 21 and an engagement piece 22 projecting from the base portion 21 in the mounting direction L of the connector 3.

  The connector 3 includes a connector resin portion 3A made of a first material and an arm resin portion 3B made of a second material different from the first material, as shown in FIGS. The arm resin portion 3B has a proximal end attachment portion 330 embedded in the connector resin portion 3A, and an engagement arm portion 33 which protrudes from the connector resin portion 3A and is elastically deformed to engage with the engagement piece 22. The Young's modulus of the second material is smaller than the Young's modulus of the first material.

The connector support 1 of this embodiment will be described in detail below.
As shown in FIG. 2, the connector support 1 is attached to various mechanical parts 4 and is used to relay the electrical wiring 42 in the various mechanical parts 4. Further, the bracket 2 of the connector support 1 is attached to the mechanical component 4 on which the electrical wiring 42 is performed, and the main body 30 of the connector resin portion 3A constituting the connector 3 of the connector support 1 is assembled to the mechanical component 4 It is inserted and arranged in the arrangement hole 51 of the assembly part 5 as a case to be

  Further, the connector 3 includes a first female connector 41 attached to an end of the electrical wiring 42 of the mechanical component 4 and a second female connector 61 attached to the side of the control device 6 connecting the mechanical component 4. It is attached. The first female connector 41 is attached to a portion (a first mounting portion 35 described later) of the connector 3 facing the bracket 2 and disposed inside the assembly component 5. The second female connector 61 is attached to a portion (a second mounting portion 36 described later) of the connector 3 exposed to the outside from the arrangement hole 51 of the assembly component 5.

  Then, in a state where the connector support 1 is attached to the mechanical component 4, when the assembly component 5 is assembled to the mechanical component 4, the connector 3 in the connector support 1 floats with respect to the bracket 2. The position of the connector 3 with respect to the arrangement hole 51 of the assembly component 5 is adjusted. As a result, an error in the position between the connector support 1 and the arrangement hole 51 when the mechanical component 4 and the assembly component 5 are assembled is absorbed. Then, the second female connector 61 is attached to the connector 3 disposed in the disposition hole 51 of the assembly component 5.

  As shown in FIG. 2, the mechanical component 4 of this embodiment is a valve body for controlling the operation of an automatic transmission used in a vehicle or the like, and the assembly component 5 is a case of the automatic transmission. A plurality of spool valves operated by an actuator such as a solenoid are disposed in the valve body. The first female connector 41 is provided at the end of the electrical wiring 42 connected to the actuator of the spool valve. Although not shown in the drawings, the second female connector 61 is provided at an end portion of the electric wiring connected to the control device 6 of the automatic transmission or on a circuit board of the control device 6 of the automatic transmission. Then, the connector 3 relays the electrical wiring 42 connected to the actuator of the spool valve, and the electrical wiring 42 is connected to the control device 6.

  The mechanical component 4 and the assembly component 5 can be various components other than the valve body and the case. In addition to the actuator, the connector 3 in the connector support 1 can also be used to relay the electrical wiring when electrically connecting various sensors to the control device 6. Further, the connector 3 in the connector support 1 can be used in various applications where relaying of electrical wiring is required.

  As shown in FIG. 2, the connector resin portion 3A is formed with a first mounting portion 35 to which the first female connector 41 is mounted and a second mounting portion 36 to which the second female connector 61 is mounted. . The first mounting portion 35 is formed on the bracket 2 side in the mounting direction L of the connector 3, and the second mounting portion 36 is formed on the side of the connector 3 opposite to the bracket 2 side.

  A plurality of connector terminals 37 are inserted into the main body portion 30 of the connector resin portion 3A along the mounting direction L. One end portions 371 of the plurality of connector terminals 37 are exposed to the outside in the first mounting portion 35, and the other ends 372 of the plurality of connector terminals 37 are exposed to the outside in the second mounting portion 36. Each connector terminal 37 is for relaying the electrical wiring 42. The connector 3 of this embodiment constitutes a male connector to which the first female connector 41 and the second female connector 61 are attached.

  As shown in FIG. 2, on the outer periphery of the main body portion 30 of the connector resin portion 3A, a sealing member 301 for sealing the disposition hole 51 of the assembly component 5 is mounted. The sealing member 301 is configured of an elastically deformable rubber O-ring or the like. The sealing member 301 is used to seal oil, which is hydraulic fluid of an automatic transmission as the mechanical component 4, in a case as the assembly component 5.

  The first mounting portion 35 of the connector resin portion 3A has one end portion 371 of the plurality of connector terminals 37 at a position closer to the bracket 2 than the sealing position P where the sealing member 301 is mounted on the outer periphery of the connector resin portion 3A. It is formed in the surrounding state. The second mounting portion 36 of the connector resin portion 3A is formed so as to surround the other end portions 372 of the plurality of connector terminals 37 at a position on the opposite side of the sealing position P to the bracket 2 side.

  As shown in FIG. 2, an insertion recess 31 described later, into which the engagement piece 22 is inserted, and the engagement arm portion 33 are disposed at a position closer to the bracket 2 than the sealing position P. The bracket 2, the first mounting portion 35, the engagement arm 33, and the insertion recess 31 disposed in the case as the assembly component 5 are located at the front end side L1 in the mounting direction L relative to the sealing position P. It is disposed in the environment R1 which can come in contact with the oil. On the other hand, the second mounting portion 36 disposed outside the case as the assembly component 5 is separated from the sealing position P by the sealing position P at the position of the rear end side L2 in the mounting direction L with the oil. It is arranged in the environment R2 which does not contact.

  The first material of the connector resin portion 3A is made of a synthetic resin containing glass fiber. The first material of this embodiment is made of one containing polyphenylene sulfide resin (PPS resin) and glass fiber (glass fiber) in order to enhance heat resistance and oil resistance. The content of glass fibers in the first material is 40% by mass. The content of glass fiber can be changed as appropriate. Glass fiber is mixed in the whole of PPS resin. The Young's modulus (longitudinal elastic modulus) of the first material is 14000 MPa.

  The second material of the arm resin portion 3B is made of a synthetic resin containing no glass fiber. The second material of this embodiment contains a polyamide resin (PA6T) in order to keep heat resistance and oil resistance high and to make the Young's modulus small (to make it easy to bend). The Young's modulus (longitudinal elastic modulus) of the second material is 2400 MPa.

  By mixing glass fiber into the synthetic resin, the heat resistance and oil resistance of the material are improved. On the other hand, when the glass fiber is mixed in the synthetic resin, the material becomes hard (the bending strength becomes high), and it becomes difficult to elastically deform (become hard to bend). The second material of the present embodiment has a Young's modulus smaller than that of the first material containing glass fiber by not containing glass fiber. In the present embodiment, the Young's modulus of the first material and the Young's modulus of the second material can be easily made different depending on the presence or absence of the glass fiber.

  The configurations of the first material and the second material of the present embodiment are an example. Various synthetic resins having heat resistance and oil resistance can be used for the first material and the second material.

  The second material may also contain glass fibers. In this case, the content of glass fibers in the second material is preferably smaller than the content of glass fibers in the first material.

  In addition, the first material and the second material can both be made of a synthetic resin containing no glass fiber. In this case, the Young's modulus of the synthetic resin constituting the second material is made smaller than the Young's modulus of the synthetic resin constituting the first material.

  The first material of the connector resin portion 3A is superior in oil resistance to oil as compared with the second material of the arm resin portion 3B. Here, oil resistance refers to the property of being less likely to change in properties even when in contact with oil for a long time. Then, the oil resistance of the connector resin portion 3A constituting the majority of the connector 3 is improved, and the bending resistance is improved even if only the oil resistance of the arm resin portion 3B constituting the part of the connector 3 is slightly reduced.

  As shown in FIG. 4, the proximal end attachment portion 330 of the arm resin portion 3B is not exposed to the surface of the connector resin portion 3A. In other words, the entire surface of the proximal end attachment portion 330 is in contact with the connector resin portion 3A. The proximal end attachment portion 330 refers to a portion of the arm resin portion 3B embedded in the connector resin portion 3A. The arm resin portion 3B is insert-molded to be integrated with the connector resin portion 3A. That is, the connector resin portion 3A integral with the arm resin portion 3B can be molded by arranging the arm resin portion 3B molded by the second material in a molding die and filling the first material in a liquid state in the molding die. it can. The connector 3 having the connector resin portion 3A and the arm resin portion 3B can be molded by performing two-color molding or the like.

  The proximal end attachment portion 330 must not be exposed to the surface of the connector resin portion 3A located on the rear end side L2 of the sealing position P, and be in contact with other members such as the connector terminal 37 and the sealing member 301. For example, it can be formed into any shape. Even when oil penetrates into the interface between the connector resin portion 3A and the arm resin portion 3B by the entire surface of the proximal end attachment portion 330 being in contact with the connector resin portion 3A, this oil may temporarily occur. However, it is possible to prevent leakage to the outside of the case as the assembly part 5.

  As shown in FIG. 4, the proximal end attachment portion 330 has a shape that prevents the arm resin portion 3B from being detached from the connector resin portion 3A. The proximal end attachment portion 330 has a boundary portion 330A located at the boundary with the engaging arm portion 33, and a back side portion 330B located behind the boundary portion 330A and having a width larger than the width of the boundary portion 330A. Have. The connector resin portion 3A has a hooking portion 330C adjacent to the front side of the back side portion 330B for locking the back side portion 330B. Here, the near side refers to the side near the engagement arm portion 33 and near the surface of the connector resin portion 3A. Further, the back side means the side located far from the engagement arm portion 33 and located inside the connector resin portion 3A. Then, the back side portion 330B is locked by the locking portion 330C, whereby the arm resin portion 3B is prevented from being separated from the connector resin portion 3A.

  As shown in FIGS. 3, 6 and 7, in a state where the connector 3 is attached to the bracket 2, the first orthogonal direction as a planar direction orthogonal to the attachment direction L with respect to the bracket 2 is the connector 3 Misalignment (floating) is possible in D and in the second orthogonal direction W. In FIGS. 2 to 6, the arrow Y indicates that the connector 3 can move relative to the bracket 2.

  The mounting direction L in the connector support 1 is a direction in which the connector 3 is mounted on the bracket 2 and is a direction in which the engagement piece 22 of the bracket 2 protrudes. The first orthogonal direction D is a direction in which the engaging arm portion 33 is elastically deformed by the engaging piece 22 when the connector 3 is attached to the bracket 2, and the thickness direction of the engaging arm portion 33 and the engaging piece 22 It corresponds to The second orthogonal direction W corresponds to the width direction of the engagement arm 33 and the engagement piece 22.

  As shown in FIGS. 2 to 4, the engagement portion 23 is formed on the engagement piece 22 of the bracket 2. In the engagement arm portion 33 of the connector 3, an engaged portion 34 engaged with the engagement portion 23 is formed. The connector resin portion 3A of the connector 3 is formed with an insertion recess 31 into which the engagement piece 22 is inserted in the mounting direction L. The engagement arm portion 33 is disposed on the back side of the insertion recess 31. In other words, the engagement arm portion 33 faces the engagement piece 22 from the inner side D2 in the first orthogonal direction D orthogonal to the mounting direction L.

  As shown in FIGS. 1, 4 and 5, the engagement piece 22 can move relative to the insertion recess 31 in a planar direction orthogonal to the mounting direction L. The plane direction refers to all directions orthogonal to the mounting direction L. The plane direction includes the first orthogonal direction D, and the second orthogonal direction W orthogonal to the mounting direction L and the first orthogonal direction D.

  A portion of the insertion recess 31 is formed by the guide piece 32 that faces the engagement piece 22 from the outer side D1 in the first orthogonal direction D. The guide piece 32 is formed with a notch 321 which allows the engagement between the engaging portion 23 and the engaged portion 34 to be visually recognized from the outside.

  In addition to the engagement piece 22, the base portion 21 of the bracket 2 is provided with a pair of support portions 24 projecting in the mounting direction L to support the connector 3. The bracket 2 is formed by bending a metal plate, and the engagement piece 22 and the pair of support portions 24 are formed by bending the base portion 21. The engagement piece 22 and the pair of support portions 24 project from the base portion 21 toward the connector 3 in the mounting direction L.

  As shown in FIG. 1, engaging portions 241 and 381 engaging with each other are provided on the pair of support portions 24 and the outer peripheral portion 38 of the connector 3. The engaging portions 241 and 381 are constituted by an engaging hole 241 provided in the support portion 24 and an engaging convex portion 381 provided in the outer peripheral portion 38 and disposed in the engaging hole 241. As shown in FIG. 3, a gap s1 is formed between the pair of support portions 24 and the outer peripheral portion 38 of the connector 3 to allow the connector 3 to move in the second orthogonal direction W with respect to the bracket 2. ing. Further, as shown in FIG. 5, a gap s2 is formed between the engagement piece 22 and the insertion recess 31 for enabling the engagement piece 22 to move in the second orthogonal direction W with respect to the insertion recess 31. It is done.

  As shown in FIGS. 1 and 6, the engagement hole 241 is formed as a long hole elongated in the first orthogonal direction D, and the engagement convex portion 381 can move freely relative to the engagement hole 241. The connector 3 can move in the first orthogonal direction D with respect to the bracket 2. In the first orthogonal direction D and the second orthogonal direction W, the movable amount of the connector 3 with respect to the bracket 2 can be determined within a range of 2 to 6 mm, for example.

  As shown in FIG. 8, the guide pieces 32 of the connector 3 are formed separately on both sides in the second orthogonal direction W by forming the cutouts 321. The guide pieces 32 face the engagement piece 22 from the outside D1 in the first orthogonal direction D on both sides of the engagement piece 22 of the bracket 2 in the second orthogonal direction W. The guide piece 32 constitutes a wall portion of the outside D <b> 1 in the first orthogonal direction D in the insertion recess 31. The insertion recess 31 is formed separately on both sides in the second orthogonal direction W by the guide pieces 32 separated on both sides in the second orthogonal direction W.

  As shown in FIGS. 4 and 5, the engaging piece 22 of the bracket 2 is formed in a plate shape whose thickness direction is directed in the first orthogonal direction D. The engagement portion 23 of the engagement piece 22 is formed by an engagement hole which penetrates the engagement piece 22 in the first orthogonal direction D. The engaged portion 34 of the engaging arm portion 33 is formed by an engaging protrusion which is inserted into the engaging hole as the engaging portion 23 and is locked to the edge of the engaging hole. The engagement protrusion as the engaged portion 34 is provided so as to protrude on the outer side D1 in the first orthogonal direction D of the engagement arm portion 33.

  As shown in FIG. 4, the engagement arm portion 33 of the connector 3 is located on the inner side D2 in the first orthogonal direction D than the guide piece 32. The engagement arm portion 33 has a fulcrum portion 331 forming a fulcrum at the time of elastic deformation at the end of the rear end side L2 in the mounting direction L, and at the end of the front end side L1 in the mounting direction L A joint 34 is provided. The front end side L1 in the mounting direction L refers to the side on which the bracket 2 is disposed with respect to the connector 3, and the rear end side L2 in the mounting direction L refers to the side opposite to the front end L1. Say.

  The fulcrum portion 331 protrudes from the connector 3 to the outer side D1 in the first orthogonal direction D in order to secure an elastic deformation amount of the engagement arm portion 33, and then is bent on the front end side L1 in the mounting direction L . In other words, the fulcrum portion 331 is formed to be bent in an L shape. The engagement arm portion 33 is formed as long as possible in the mounting direction L in order to increase the amount of elastic deformation. Specifically, the fulcrum portion 331 is positioned on the rear end side L2 in the mounting direction L than the base end surface 221 in the mounting direction L of the engagement piece 22 inserted into the insertion recess 31. Thus, the engaging arm 33 is formed long in the mounting direction L, so that the engaging arm 33 is less likely to be broken when it is elastically deformed.

  As shown in FIGS. 4 and 5, the engagement arm portion 33 is a first orthogonal direction from the outer surfaces 323 and 324 in the first orthogonal direction D of the wall portions (guide pieces 32 etc.) constituting the connector resin portion 3A. It is formed at a position where it is sunk to the inner side D2 of D. Thus, the finger or the like of the operator is prevented from unintentionally touching the engagement arm portion 33. A pair of slits 333 parallel to each other is formed from the end of the front end side L1 in the mounting direction L in the connector 3 to the rear end side L2. The engagement arm portion 33 is formed between the pair of slits 333.

  As shown in FIG. 4, since the engagement piece 22 can be displaced in the first orthogonal direction D of the insertion recess 31, the width of the insertion recess 31 in the first orthogonal direction D is the first width of the engagement piece 22. It is larger than the thickness in the orthogonal direction D. Therefore, when the engagement piece 22 is inserted into the insertion recess 31, when the insertion position of the engagement piece 22 in the first orthogonal direction D of the insertion recess 31 is not limited at all, the engagement piece 22 is engaged. There is a possibility that the arm 33 is elastically deformed to a large extent. In this case, the engagement arm portion 33 is placed in a state of being easily broken.

  Therefore, in order to limit the amount of elastic deformation of the engaging arm 33 when the connector 3 is attached to the bracket 2, as shown in FIGS. 5 and 9, the second orthogonal of the engaging arm 33 in the connector 3 At positions adjacent to both sides in the direction W, a pair of restricting projections 39 that protrude to the outer side D1 in the first orthogonal direction D and are disposed in the insertion recess 31 are provided. As shown in FIG. 10, the pair of limiting protrusions 39 limits the amount by which the engaging arm portion 33 bends inward in the first orthogonal direction D while the engaging piece 22 is inserted into the insertion recess 31. At the same time, as shown in FIGS. 4 and 5, when the engagement piece 22 is inserted into the insertion recess 31, it is inserted into the engagement hole as the engagement portion 23.

  Thus, the pair of restriction protrusions 39 prevents breakage of the engagement arm portion 33 when the connector 3 is attached to the bracket 2, and after the attachment of the connector 3 to the bracket 2, 1 Allow positional deviation (floating) in the orthogonal direction D. As shown in FIG. 5, between the engaging hole as the engaging portion 23 and the pair of restricting projections 39, the pair of restricting projections 39 can be displaced in the second orthogonal direction W with respect to the engaging hole. A gap s3 is formed for this purpose.

  Further, as shown in FIG. 4, the engagement piece 22 is inserted into the insertion recess 31 at the corner of the front end side L1 of the engagement protrusion L as the engaged portion 34 of the engagement arm portion 33 in the mounting direction L. A tapered surface 342 is formed to guide the. Further, tapered surfaces 391 and 325 for guiding the insertion of the engagement piece 22 into the insertion recess 31 are also formed at the corner of the front end side L1 in the mounting direction L of the pair of restriction protrusions 39 and the guide piece 32. There is.

First, the bracket 2 is attached to the mechanical component 4 alone by an operator or the like. Further, the first female connector 41 attached to the end of the electrical wiring 42 of the mechanical component 4 is mounted by the worker or the like to the first mounting portion 35 of the connector 3 in a state of being removed from the bracket 2. Next, the connector 3 to which the first female connector 41 is attached is attached to the bracket 2 by an operator or the like.

  At this time, the engagement piece 22 of the bracket 2 is inserted into the insertion recess 31 of the connector 3. Then, an engagement protrusion as the engaged portion 34 of the engagement arm portion 33 of the connector 3 and a pair of restriction protrusions 39 of the connector 3 are disposed in the engagement hole as the engagement portion 23 of the engagement piece 22. As a result, the pair of support portions 24 of the bracket 2 and the outer peripheral portion 38 of the connector 3 are engaged. Thus, the connector support 1 is attached to the mechanical component 4, and in the connector support 1, the connector 3 to which the first female connector 41 is attached can move relative to the bracket 2.

  Then, the assembly part 5 is assembled to the mechanical part 4 such that the second mounting portion 36 and the main body 30 of the connector 3 are inserted into the arrangement holes 51 of the assembly part 5 by the operator or the like. . At this time, since the connector 3 can move in the first orthogonal direction D and the second orthogonal direction W with respect to the bracket 2, the main body 30 of the connector 3 can be easily arranged in the arrangement hole 51. Thereafter, the second female connector 61 on the control device 6 side is attached to the second attachment portion 36 of the connector 3 which protrudes to the outside of the assembly component 5 through the disposition hole 51.

Then, by reducing the Young's modulus of the second material, the engagement arm portion 33 formed in the arm resin portion 3B can be easily elastically deformed. On the other hand, the connector resin portion 3A can be made of the first material excellent in heat resistance and oil resistance without considering ease of elastic deformation.

  Since the engaging arm 33 is easily elastically deformed by the second material, the engaging operation of the engaging arm 33 of the connector 3 with the engaging piece 22 of the bracket 2 can be facilitated, and the engaging arm The part 33 can be protected from breakage. On the other hand, the heat resistance and oil resistance of the connector 3 can be maintained high by the first material constituting the connector resin portion 3A.
