[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially identical. Note that in this specification, ordinal numbers are used only to distinguish between parts, members, portions, positions, directions, etc., and do not indicate order or priority.

[0010] [Embodiment] FIG. 1 is a perspective view of a connector 1 applied to a wire harness WH according to an embodiment. The connector 1 of this embodiment shown in FIG. 1 is incorporated into the wire harness WH to be routed in a vehicle such as an automobile. Here, the wire harness WH is, for example, a collection of wiring materials W used for power supply and signal communication to connect various devices mounted on the vehicle, and the wiring materials W are connected to the various devices using a connector 1 or the like. The wire harness WH of this embodiment includes, for example, a plurality of conductive wiring materials W and a connector 1 provided at the ends of the plurality of wiring materials W and attached to an attachment object 100. In addition, the wire harness WH may further include a protector, a grommet, etc.

[0011] In the following description, of the first, second, and third directions that intersect with each other, the first direction will be referred to as the "axial direction X," the second direction will be referred to as the "width direction Y," and the third direction will be referred to as the "height direction Z." Here, the axial direction X, width direction Y, and height direction Z are approximately perpendicular to each other. The axial direction X typically corresponds to the extension direction of the wiring material W, the insertion direction of the wiring material W into the connector 1, the longitudinal direction of the connector 1, etc. The width direction Y typically corresponds to the radial direction of the wiring material W, the width direction (left-right direction) of the connector 1, etc. The height direction Z typically corresponds to the radial direction of the wiring material W, the height direction (up-down direction) of the connector 1, etc. Furthermore, unless otherwise specified, each direction used in the following description will be described as the direction when the wiring material W is assembled to the connector 1.

[0012] Fig. 2 is an exploded perspective view of the connector 1, and Fig. 3 is a cross-sectional view of the connector 1. As shown in Figs. 2 and 3, the wiring material W includes, for example, a plurality of first wiring materials W1 and a plurality of second wiring materials W2 each having a smaller diameter than the first wiring materials W1. The first wiring material W1 is, for example, an electric wire electrically connected to the terminal 10, and the second wiring material W2 is, for example, a lead wire electrically connected to a temperature sensor 90 such as a thermistor. The first wiring material W1 and the second wiring material W2 each include a linear conductor portion having conductivity and an insulating coating portion having insulation properties that covers the outside of the conductor portion.

[0013] The first wiring material W1 and the second wiring material W2 each extend linearly along the axial direction X and are formed to extend with approximately the same diameter relative to the axial direction X (extension direction). Furthermore, the first wiring material W1 and the second wiring material W2 are formed, for example, such that the cross-sectional shape of the conductor portion (cross-sectional shape intersecting the axial direction X) is approximately circular and the cross-sectional shape of the insulating coating portion is approximately annular, and are formed to have an approximately circular cross-sectional shape overall. The insulating coating portion of the first wiring material W1 is stripped off at least one end, and a terminal 10 is crimped to the conductor portion exposed from the insulating coating portion. The first wiring material W1 is also referred to as a terminal-attached electric wire, etc.

[0014] The connector 1 includes, for example, a terminal 10, a housing 20, a sealing member 30 (described later), a rear holder 40, a spacer 50, packings 60 and 70, a fastening member 80, and a temperature sensor 90. The terminal 10 is a terminal fitting made of a conductive metal material and is electrically connected to a terminal of a mating connector (not shown). The terminal 10 includes, for example, an electrical connection portion electrically connected to the terminal of the mating connector and a wire crimping portion electrically connected to an end of the first wiring material W1. When the connector 1 is attached to an attachment object 100 (see FIG. 3), the terminal 10 is positioned within a through hole 101 of the attachment object 100. The connector 1 is also referred to as a charging inlet, etc.

[0015] The housing 20 is the part of the connector 1 that holds the terminals 10 therein and mates with a mating connector. The housing 20 is formed by combining multiple parts, including, for example, an inner housing 21 and an outer housing 22 (see FIG. 2). The inner housing 21 and the outer housing 22 are each made of an insulating synthetic resin material or the like.

[0016] The inner housing 21 includes, for example, a cylindrical portion 21a, an attachment portion 21b, and a terminal accommodating portion 21c. The inner housing 21 is formed such that the cylindrical portion 21a, the attachment portion 21b, and the terminal accommodating portion 21c are integrally formed. The cylindrical portion 21a is formed, for example, in a cylindrical shape extending along the axial direction X. The cylindrical portion 21a accommodates the first wiring material W1 and the second wiring material W2, as well as a sealing member 30, a spacer 50, a temperature sensor 90, and the like, which will be described later.

[0017] The mounting portion 21b is a portion that protrudes radially outward from one end of the cylindrical portion 21a in the axial direction X. The mounting portion 21b is provided with a mounting hole to which a fastening member 80 such as a bolt is attached along the axial direction X. In this embodiment, the inner housing 21 is fixed to the mounting object 100 by fastening the fastening member 80 to the mounting portion 21b and the mounting object 100. The inner housing 21 is provided with a plurality of mounting portions 21b, for example, spaced apart from one another in the circumferential direction of the cylindrical portion 21a.

[0018] The terminal accommodating portion 21c is a portion that holds the terminal 10 provided at the tip end of the first wiring material W1 inside. The terminal accommodating portion 21c is formed, for example, in a cylindrical shape extending along the axial direction X, and protrudes further toward one end side in the axial direction X (the attachment target 100 side) than the tubular portion 21a. The other end of the terminal accommodating portion 21c in the axial direction X is connected to an inner wall (see FIG. 3) that extends along the radial direction inside the tubular portion 21a, and the internal space of the terminal accommodating portion 21c and the internal space of the tubular portion 21a are communicated along the axial direction X. The inner housing 21 is provided with a plurality of terminal accommodating portions 21c, for example, spaced apart from one another in the radial direction of the tubular portion 21a.

[0019] The rear holder 40 covers the open end of the cylindrical portion 21a on the other end side in the axial direction X. The rear holder 40 includes, for example, a holder main body that covers the open end of the cylindrical portion 21a, and a locked portion that is locked with a locking portion formed on the outer peripheral surface of the cylindrical portion 21a. The locking portion is formed in a claw shape on the outer peripheral surface of the cylindrical portion 21a, and the locked portion is formed in a locking hole shape at a position corresponding to the locking portion of the holder main body. With the holder main body covering the open end of the cylindrical portion 21a, the rear holder 40 is integrated with the inner housing 21 by a so-called snap fit between the locking portion and the locked portion.

[0020] The spacer 50 is a member interposed between the outer peripheral surface of the first wiring material W1 and the inner peripheral surface of the tubular portion 21a when the first wiring material W1 is attached inside the inner housing 21. The spacer 50 has a wiring material insertion hole into which the first wiring material W1 is inserted along the axial direction X. In this embodiment, the connector 1 is provided with a plurality of spacers 50 corresponding to each of the plurality of first wiring materials W1. Each spacer 50 limits the radial movement of the first wiring material W1 relative to the inner housing 21.

[0021] The packing 60 prevents foreign matter such as moisture from entering the inside of the terminal accommodating portion 21c. The packing 60 is made of an elastically deformable material such as rubber or resin. The packing 60 is formed, for example, in a cylindrical shape that conforms to the outer circumferential surface of the terminal 10, and is fitted onto the outer circumferential surface of the base end of the terminal 10. When the terminal 10 is inserted into the terminal accommodating portion 21c, the packing 60 is interposed between the outer circumferential surface of the base end of the terminal 10 and the inner circumferential surface of the terminal accommodating portion 21c.

[0022] The packing 70 prevents moisture and other foreign matter from entering the inside of the connector 1 through an annular gap between the through hole 101 of the attachment object 100 and the cylindrical portion 21a of the inner housing 21. The packing 70 is made of an elastically deformable material such as rubber or resin. The packing 70 is formed, for example, in a substantially cylindrical shape that follows the outer peripheral surface of the cylindrical portion 21a, and is fitted to the outer peripheral surface of the cylindrical portion 21a. When the inner housing 21 is fixed to the attachment object 100, the packing 70 is interposed between the outer peripheral surface of the cylindrical portion 21a and the inner peripheral surface of the through hole 101.

[0023] The fastening member 80 fastens the inner housing 21 and the outer housing 22 to the object 100 along the axial direction X. The fastening member 80 is configured, for example, by a bolt having a shank with a male thread and a head with a larger diameter than the shank. The fastening member 80 is fastened to a screw hole in the object 100 with the shank penetrating the mounting portion 21b along the axial direction X, with the mounting portion 21b sandwiched between the head of the bolt and the object 100.

[0024] The temperature sensor 90 measures, for example, the temperature of the terminal 10. The temperature sensor 90 is configured, for example, by a thermistor or the like, and is provided in contact with the terminal 10, i.e., in a state of being thermally connected to the terminal 10. The temperature sensor 90 is electrically connected to the end of the second wiring material W2, and the measured value of the temperature of the terminal 10 is taken out of the connector 1 via the second wiring material W2.

[0025] FIG. 4 is a perspective view of the multiple wiring materials W and the sealing member 30 of the connector 1, and FIG. 5 is a front view of the sealing member 30. As shown in FIGS. 4 and 5, the sealing member 30 has, for example, multiple insertion holes 32 into which the multiple wiring materials W are inserted along the axial direction X, and seals the outer surfaces of the multiple wiring materials W inserted into the multiple insertion holes 32. In this embodiment, the connector 1 is provided with multiple sealing members 30 corresponding to the multiple first wiring materials W1. Each sealing member 30 has three insertion holes 32, including a first insertion hole 32a into which the first wiring material W1 is inserted and a pair of second insertion holes 32b (see FIG. 5) into which a pair of second wiring materials W2 are inserted. The sealing member 30 is formed of an elastically deformable material such as rubber or resin. The sealing member 30 is also called a wire packing, a rubber stopper, a bushing, etc.

[0026] Here, in this embodiment, the sealing member 30 is configured to include a main body portion 31 and a retaining portion 34. The main body portion 31 is a portion of the sealing member 30 in which three insertion holes 32 are provided, into which the above-mentioned first wiring material W1 and second wiring material W2 are respectively inserted along the axial direction X. In this embodiment, the main body portion 31 is formed of a material having relatively higher elasticity than the retaining portion 34, such as rubber. In other words, when the first wiring material W1 and the second wiring material W2 are inserted (press-fitted) into each of the three insertion holes 32, the main body portion 31 is elastically deformable (expandable) along the radial direction of each insertion hole 32.

[0027] The retaining portions 34 are provided to individually surround the three insertion holes 32 in the main body portion 31 of the seal member 30 and are portions that retain the peripheries of the three insertion holes 32. In this embodiment, the retaining portions 34 are formed of a material having relatively higher rigidity than the main body portion 31, such as a synthetic resin. That is, when the first wiring material W1 and the second wiring material W2 are inserted (press-fitted) into each of the three insertion holes 32, the retaining portions 34 function as portions that limit elastic deformation along the radial direction of the main body portion 31 and retain the main body portion 31 so that it is elastically deformed (compressed) approximately uniformly along the circumferential direction of each insertion hole 32. The retaining portions 34 are integrally molded (integrated) with the main body portion 31, for example, by insert molding, two-color molding, or the like.

[0028] The main body 31 also has a plurality of tubular portions 33 extending along the axial direction X, each having an insertion hole 32 formed therein. Specifically, the plurality of tubular portions 33 include a first tubular portion 33a into which a first wiring material W1 of the plurality of wiring materials W is inserted, and a second tubular portion 33b into which a second wiring material W2 of the plurality of wiring materials W is inserted. In this embodiment, the main body 31 is provided with one first tubular portion 33a corresponding to the first wiring material W1, and a pair of second tubular portions 33b corresponding to the second wiring material W2. The outer diameters of the pair of second tubular portions 33b are each formed smaller than the outer diameter of the first tubular portion 33a. The pair of second tubular portions 33b also have second insertion holes 32b with diameters smaller than the first insertion holes 32a of the first tubular portion 33a.

[0029] The holding portion 34 is provided with a plurality of insertion holes 35, including a first insertion hole 35a through which the first cylindrical portion 33a is inserted along the axial direction X and a pair of second insertion holes 35b through which the second cylindrical portion 33b is inserted along the axial direction X. The first insertion hole 35a is formed in a substantially circular shape that follows the outer shape of the first cylindrical portion 33a and is provided on one end side of the holding portion 34 in the height direction Z corresponding to the first cylindrical portion 33a. The pair of second insertion holes 35b are each formed in a circular shape that follows the outer shape of the second cylindrical portion 33b and are provided side by side along the width direction Y on the other end side of the holding portion 34 in the height direction Z corresponding to the second cylindrical portion 33b. In this embodiment, the periphery of the first cylindrical portion 33a and the peripheries of the pair of second cylindrical portions 33b are integrally held by the first insertion hole 35a and the pair of second insertion holes 35b of the holding portion 34.

[0030] Fig. 6 is a cross-sectional view of the first cylindrical portion 33a of the sealing member 30. As shown in Fig. 6, the first cylindrical portion 33a is provided on one end surface 31a in the axial direction X of the main body portion 31, and protrudes cylindrically from the one end surface 31a along the axial direction X. A first insertion hole 32a is provided inside the first cylindrical portion 33a, into which the first wiring material W1 is inserted along the axial direction X. The first insertion hole 32a is provided between one end surface in the axial direction X of the first cylindrical portion 33a and the other end surface in the axial direction X of the main body portion 31, and penetrates the first cylindrical portion 33a and the main body portion 31 along the axial direction X.

[0031] The first insertion hole 32a is provided with an inner peripheral lip portion 31c that protrudes radially inward. The inner peripheral lip portion 31c is a pleated water-stopping portion formed in a substantially annular shape along the inner peripheral surface of the first insertion hole 32a. In this embodiment, two inner peripheral lip portions 31c are provided on the inner peripheral surface of the first insertion hole 32a, aligned in the axial direction X. When the first wiring material W1 is inserted (press-fitted) into the first insertion hole 32a, the inner peripheral lip portions 31c come into contact with the outer peripheral surface of the first wiring material W1 to seal the space between the outer peripheral surface and the first insertion hole 32a. The inner peripheral lip portion 31c is configured to elastically deform and adhere closely to the outer peripheral surface of the first wiring material W1, sealing the annular space between the outer peripheral surface and the inner peripheral surface of the first insertion hole 32a.

[0032] Additionally, an outer peripheral lip portion 31b protruding radially outward is provided on the outer peripheral surface of the main body portion 31. The outer peripheral lip portion 31b is a pleated water-stopping portion formed in a substantially annular shape along the outer peripheral surface of the main body portion 31. In this embodiment, two outer peripheral lip portions 31b are provided on the outer peripheral surface of the main body portion 31 side by side in the axial direction X. The two outer peripheral lip portions 31b are also aligned with the two inner peripheral lip portions 31c in the radial direction (height direction Z). When the seal member 30 is inserted (press-fitted) into the inner housing 21, the outer peripheral lip portion 31b contacts the inner peripheral surface of the inner housing 21 to seal the gap between the inner peripheral surface and the inner peripheral surface. The outer peripheral lip portion 31b is configured to elastically deform and closely contact the inner peripheral surface of the inner housing 21 to seal the annular space between the inner peripheral surface and the outer peripheral surface of the main body portion 31. In this embodiment, the inner housing 21 is an example of a member provided on the outer peripheral side of the main body portion 31.

[0033] 7 is a cross-sectional view of the second tubular portion 33b of the sealing member 30. As shown in FIG. 7, the second tubular portion 33b is provided on one end surface 31a in the axial direction X of the main body portion 31, and protrudes cylindrically from the one end surface 31a along the axial direction X. A second insertion hole 32b is provided inside the second tubular portion 33b, into which the second wiring material W2 is inserted along the axial direction X. The second insertion hole 32b is provided between one end surface in the axial direction X of the second tubular portion 33b and the other end surface in the axial direction X of the main body portion 31, and penetrates the second tubular portion 33b and the main body portion 31 along the axial direction X.

[0034] The second insertion hole 32b is provided with an inner lip portion 31c that protrudes radially inward. The inner lip portion 31c is a pleated water-stopping portion formed in a substantially annular shape along the inner peripheral surface of the second insertion hole 32b. In this embodiment, three inner lip portions 31c are provided on the inner peripheral surface of the second insertion hole 32b, lined up in the axial direction X. When the second wiring material W2 is inserted (press-fitted) into the second insertion hole 32b, the inner lip portions 31c come into contact with the outer peripheral surface of the second wiring material W2 to seal the space between the outer peripheral surface and the second insertion hole 32b. The inner lip portions 31c are configured to elastically deform and adhere closely to the outer peripheral surface of the second wiring material W2, sealing the annular space between the outer peripheral surface and the inner peripheral surface of the second insertion hole 32b.

[0035] In this embodiment, the second cylindrical portion 33b protrudes by a larger amount in the axial direction X than the first cylindrical portion 33a protrudes by a larger amount in the axial direction X. As a result, a step portion 36 is formed between one end face in the axial direction X of the holding portion 34 that covers the periphery of the second cylindrical portion 33b and one end face in the axial direction X of the holding portion 34 that covers the periphery of the first cylindrical portion 33a. In this embodiment, the holding portion 34 includes an extending portion that extends along the axial direction X between one end and the other end of the first insertion hole 32a and the second insertion hole 32b, and the periphery of each of the first insertion hole 32a and the second insertion hole 32b is covered by this extending portion.

[0036] As described above, the seal member 30, connector 1, and wire harness WH of this embodiment are configured to include a main body 31 having a plurality of insertion holes 32 into which each of a plurality of wiring materials W is inserted along the axial direction X, and sealing the outer surfaces of the plurality of wiring materials W inserted into the plurality of insertion holes 32, and retaining portions 34 provided so as to surround the plurality of insertion holes 32 in the main body 31 individually and retaining the peripheries of each of the plurality of insertion holes 32, the main body 31 having relatively higher elasticity than the retaining portions 34, and the retaining portions 34 having relatively higher rigidity than the main body 31. With this configuration, when the wiring materials W are inserted (press-fitted) into each of the plurality of insertion holes 32 in the main body 31, for example, the seal member 30, connector 1, and wire harness WH can have the retaining portions 34 compress the peripheries of each of the plurality of insertion holes 32 (main body 31) approximately uniformly over the entire circumference. As a result, the sealing member 30, the connector 1, and the wire harness WH can improve the waterproofing properties of the wiring materials W.

[0037] Furthermore, in the seal member 30, connector 1, and wire harness WH of this embodiment, the main body 31 extends along the axial direction X and has a plurality of tubular portions 33, each having one insertion hole 32 therein, and the holding portion 34 holds the periphery of each of the plurality of tubular portions 33. With this configuration, the seal member 30, connector 1, and wire harness WH can relatively easily be configured such that the holding portion 34 holds the periphery of each of the plurality of insertion holes 32 with the plurality of tubular portions 33, for example.

[0038] In addition, in the sealing member 30, connector 1, and wire harness WH of this embodiment, the multiple tubular portions 33 are configured to include a first tubular portion 33a into which a first wiring material W1 of the multiple wiring materials W is inserted, and a second tubular portion 33b into which a second wiring material W2 of the multiple wiring materials W, which has a smaller diameter than the first wiring material W1, is inserted, and the retaining portion 34 is provided with multiple insertion holes 35 including a first insertion hole 35a through which the first tubular portion 33a is inserted along the axial direction X and a second insertion hole 35b through which the second tubular portion 33b is inserted along the axial direction X, and the multiple insertion holes 35 hold the peripheries of the first tubular portion 33a and the second tubular portion 33b together. With this configuration, the sealing member 30, the connector 1, and the wire harness WH can be held together around the first tubular portion 33a and the second tubular portion 33b, for example, by the multiple insertion holes 35 of the retaining portion 34, thereby improving the watertightness against multiple first wiring materials W1 and second wiring materials W2 having different outer diameters.

[0039] Furthermore, in the seal member 30, connector 1, and wire harness WH of this embodiment, the main body 31 has an outer peripheral lip portion 31b that protrudes radially outward from the outer peripheral surface of the main body 31 and provides a seal with the inner peripheral surface of the inner housing 21, which is a member provided on the outer peripheral side of the main body 31. With this configuration, the seal member 30, connector 1, and wire harness WH can improve, for example, the watertightness of the inner housing 21, which is provided on the outer peripheral side of the main body 31, by the outer peripheral lip portion 31b.

[0040] In this embodiment, an example is given in which three insertion holes 32 are provided in the sealing member 30, but the number of insertion holes 32 is not limited to this example, and for example, one, two, or four or more insertion holes 32 may be provided in the sealing member 30.

[0041] While the embodiments of the present invention have been described above, they are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. Furthermore, the specifications of each configuration, shape, and the like (structure, type, direction, format, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be modified as appropriate.
