[0004] However, in the connector described in the above-mentioned Patent Document 1, for example, it is necessary to fix the casing and the fixed wall surface of the connection object outside the tubular portion, i.e., outside the waterproof area provided by the gasket, using a fastening member, which could result in the casing becoming relatively large.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector and a wire harness that can prevent the casing from becoming large. [Means for solving the problem]

[0006] In order to achieve the above object, a connector according to the present invention comprises: a casing having a cylindrical portion that holds terminals provided at ends of electric wires therein and that is fitted with a mating connector to be connected in a mating direction; a packing that seals an annular space between an outer peripheral surface of the cylindrical portion and the mating connector; a fastening member that is attached so as to pass through an interior of the cylindrical portion in the mating direction from a through hole formed in one end face of the casing in the mating direction, and that is fixed to a fixed wall surface of the connection target when the cylindrical portion and the mating connector are fitted together; and a sealing member that seals an annular gap between the outer peripheral surface of the fastening member and the inner surface of the through hole. The fastening member is composed of a first waterproof washer having a bolt to be inserted into the through hole, an annular first washer body interposed between the head of the bolt and the circumferential edge of the through hole, and an annular first water-sealing rubber interposed between the inner surface of the first washer body and the shank of the bolt, and the sealing member is interposed between the outer peripheral surface of the shank of the bolt and the inner surface of the through hole, and is positioned adjacent to the first water-sealing rubber in the fitting direction. [Effects of the Invention]

[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 cross-sectional view of a wire harness WH to which a connector 1 according to an embodiment is applied. 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 component in which a plurality of electric wires W used for power supply and signal communication are bundled together to connect various devices mounted on the vehicle, and the plurality of electric wires W are connected to the respective devices using a connector 1 or the like. The wire harness WH of this embodiment includes, for example, a plurality of conductive electric wires W and a connector 1 provided at the ends of the plurality of electric wires W. In addition, the wire harness WH may further include a protector, a fixing device, etc.

[0011] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "mating 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 mating direction X, the width direction Y, and the height direction Z are approximately perpendicular to one another. The mating direction X typically corresponds to the insertion / removal direction (mating direction) of the connector 1 and the mating connector 110, the front-rear direction (thickness direction) of the connector 1, etc. The height direction Z typically corresponds to the longitudinal direction (up-down direction) of the connector 1, the extension direction of the electric wire W, the insertion direction of the electric wire W into the connector 1, etc. The width direction Y typically corresponds to the width direction (left-right direction) of the connector 1, etc. Furthermore, unless otherwise specified, the directions used in the following description will be described as directions in a state in which the electric wire W is assembled to the connector 1.

[0012] The electric wire W includes, for example, a linear conductor portion W1 having electrical conductivity and an insulating coating W2 having electrical insulation properties and covering the outside of the conductor portion W1. The electric wire W is an insulated electric wire in which the conductor portion W1 is covered with the insulating coating W2. In this embodiment, the conductor portion W1 is a core wire formed by bundling a plurality of conductive metal wires, but it may also be a twisted core wire formed by twisting the plurality of metal wires together. The insulating coating W2 is a wire coating that covers the outer periphery of the conductor portion W1. The insulating coating W2 is formed, for example, by extrusion molding an insulating resin material (PP, PVC, cross-linked PE, etc., appropriately selected in consideration of abrasion resistance, chemical resistance, heat resistance, etc.).

[0013] The electric wires W each extend linearly along the height direction Z and are formed to extend with approximately the same diameter in the height direction Z (extension direction). In addition, the electric wires W are formed such that, for example, the cross-sectional shape of the conductor portion W1 (cross-sectional shape intersecting with the height direction Z) is approximately circular and the cross-sectional shape of the insulating coating W2 is approximately annular, and thus the electric wires W are formed to have an approximately circular cross-sectional shape as a whole. At least one end of the electric wires W has the insulating coating W2 stripped away, and a terminal 3 (see FIG. 4), which will be described later, is crimped to the conductor portion W1 exposed from the insulating coating W2.

[0014] Here, the connector 1 of this embodiment is mechanically and electrically connected to a mating device 100 (see FIG. 1 ) to be connected. The connector 1 is fitted to a mating connector 110 by being inserted into a connector insertion hole 103 formed in a housing 101 of the mating device 100, and forms an electrical connection portion with the mating connector 110. The connector 1 is configured to include, for example, a casing 2 having a tubular portion 11A that fits with the mating connector 110, and a fastening member 40 that is inserted from a through-hole 2a formed on one end surface of the casing 2 in the fitting direction X and is fixed to a fixed wall surface 103a of the mating device 100 in a state in which the tubular portion 11A and the mating connector 110 are fitted together. The one end surface of the casing 2 is an end surface opposite to the tubular portion 11A in the fitting direction X.

[0015] The connector insertion hole 103 is provided in a wall surface 102 on one side (connector 1 side) in the mating direction X of the housing 101 of the mating device 100. The connector insertion hole 103 is, for example, a recess that is recessed from the wall surface 102 toward the other side in the mating direction X and is open toward the one side in the mating direction X. The mating connector 110 is housed inside the connector insertion hole 103. The connector insertion hole 103 is a portion into which the tubular portion 11A is inserted and fitted when the connector 1 is fitted with the mating connector 110. The opening shape of the connector insertion hole 103 is formed to follow the outer diameter shape of the tubular portion 11A. For example, the opening shape of the connector insertion hole 103 when viewed from the mating direction X is substantially elliptical.

[0016] The fixed wall surface 103a is a wall surface at the bottom of the connector insertion hole 103, and is a portion where the connector 1 is fixed by the fastening member 40. The fixed wall surface 103a is formed as a uniform flat surface. The fixed wall surface 103a is also provided with a fastening hole 104 into which the fastening member 40 is fastened. The bolt 41 of the fastening member 40 is fastened into the fastening hole 104 when the connector 1 is mated with the mating connector 110. The fastening hole 104 is a hole with a threaded groove formed on its inner circumferential surface, and the shank 41b of the bolt 41 is threaded into the fastening hole 104.

[0017] Fig. 2 is a perspective view of connector 1, Fig. 3 is a plan view of connector 1, and Fig. 4 is an exploded perspective view of connector 1. As shown in Figs. 2 to 4, connector 1 includes a casing 2 formed by combining multiple parts including, for example, a housing 10 and a shield shell 20, multiple packings 30 and 60, a fastening member 40, and a sealing member 50 (described later). Connector 1 is used in, for example, a wire harness WH having an electric power supply wire W that supplies power from an inverter to a motor in a vehicle such as a hybrid vehicle or an electric vehicle. Note that, in this embodiment, an example is shown in which connector 1 is configured as a male connector and mating connector 110 is configured as a female connector, but the present invention is not limited to this example.

[0018] The housing 10 is a portion of the casing 2 that holds the terminals 3 therein and has a cylindrical portion 11A that mates with the mating connector 110. As shown in FIG. 4 , the housing 10 is formed by combining multiple parts. Specifically, the housing 10 includes, for example, a housing main body 11, a rear cover 12, a front holder 13, and an inner housing 14. The housing main body 11, the rear cover 12, the front holder 13, and the inner housing 14 are each formed from an insulating resin material. In this embodiment, the cylindrical portion 11A is provided in the housing main body 11 of the housing 10 and protrudes cylindrically from the housing main body 11 toward the other side in the mating direction X (the mating connector 110 side).

[0019] The housing main body 11 and the rear cover 12 are members that accommodate the terminals 3 therein when assembled together. The terminals 3 are male terminal fittings made of a conductive metal material and are electrically connected to female terminals of the mating connector 110. In this embodiment, the housing main body 11 is provided with four terminals 3 spaced apart from one another in the width direction Y. Each terminal 3 includes, for example, an electrical connection portion that is electrically connected to the female terminal of the mating connector 110, and an electric wire crimping portion that is electrically connected to an end of the electric wire W. Note that, although the housing main body 11 and the rear cover 12 accommodate four terminals 3 when assembled together, the number of terminals 3 is not limited to this.

[0020] The housing body 11 is formed with openings on both sides in the mating direction X, for example. When the terminals 3 are accommodated in the cylindrical portion 11A of the housing body 11, the terminals 3 are exposed to the outside from the opening on the other side in the mating direction X, while the opening on one side in the mating direction X is closed by the rear cover 12. The housing body 11 is formed with a substantially rectangular shape when viewed from the mating direction X, for example. In a mated state in which the cylindrical portion 11A is mated with the mating connector 110, the housing body 11 faces a wall surface 102 of the mating device 100. The housing body 11 is provided with a plurality of wire insertion portions 15 at its lower end.

[0021] The wire insertion portion 15 is a portion through which the wire W is inserted. The wire insertion portion 15 is formed so as to protrude downward from the lower end of the housing body 11 in the height direction Z. The wire insertion portion 15 is formed in a cylindrical shape, and the wire W is routed inside the wire insertion portion 15 in the height direction Z. In other words, the housing body 11 holds the terminal 3 in the fitting direction X, and the wire W is drawn out along the height direction Z that is perpendicular to the fitting direction X. Here, the housing body 11 is provided with four wire insertion portions 15 aligned in the width direction Y, and the wire W is inserted into each of the four wire insertion portions 15.

[0022] The rear cover 12 is a member for closing the opening of the housing main body 11 from one side in the fitting direction X. The rear cover 12 has, for example, a cover portion 12b that covers the opening of the housing main body 11 and a plurality of locking portions 12a that lock onto the outer circumferential surface of the housing main body 11. With the cover portion 12b covering the opening of the housing main body 11, the rear cover 12 is integrated with the housing main body 11 by snap-fitting using the locking portions 12a.

[0023] The front holder 13 is, for example, a member for holding the packing 30 between itself and the housing main body 11. The front holder 13 is formed in a cylindrical shape that follows the outer peripheral surface of the cylindrical portion 11A and is fitted to the outer peripheral surface of the cylindrical portion 11A. The front holder 13 is formed in a substantially elliptical cylindrical shape when viewed from the fitting direction X, for example. The front holder 13 is integrated with the cylindrical portion 11A by claw fitting or the like, with the packing 30 sandwiched between the front holder 13 and the housing main body 11.

[0024] The packing 30 prevents foreign matter such as moisture and dust from entering the inside of the connector 1 through an annular gap between the mating connector 110 and the outer circumferential surface of the tubular portion 11A. The packing 30 is formed of an elastically deformable material such as rubber or resin. The packing 30 is formed, for example, in a substantially elliptical cylindrical shape that conforms to the outer circumferential surface of the tubular portion 11A and is fitted to the outer circumferential surface of the tubular portion 11A. In a mated state in which the tubular portion 11A is fitted to the mating connector 110, the packing 30 is interposed between the mating connector 110 and the tubular portion 11A on one side of the front holder 13 in the fitting direction X.

[0025] The inner housing 14 is a member formed separately from the housing main body 11, and is a member that receives and holds the terminals 3 along the fitting direction X when attached to the inside of the tubular portion 11A. The inner housing 14 is provided with a plurality of insertion holes 14a through which the terminals 3 are inserted along the fitting direction X. The plurality of insertion holes 14a are aligned in the width direction Y. In other words, the plurality of terminals 3 are held in a state where they are separated from one another in the width direction Y by the inner housing 14.

[0026] The shield shell 20 is a part of the casing 2 that covers the terminals 3 and the wires W, thereby preventing noise generated from the wires W from leaking outside the connector 1. As shown in Fig. 4, the shield shell 20 is formed by combining multiple parts. Specifically, the shield shell 20 includes, for example, a shell main body 21 and a lower shell 25. The shell main body 21 and the lower shell 25 are each formed, for example, from a conductive metal material.

[0027] The shell body 21 is formed, for example, in a tub shape so as to cover one side of the housing 10 in the fitting direction X. That is, the shell body 21 has an accommodation space that is open toward the other side in the fitting direction X and accommodates a rear cover 12 of the housing 10 and a part of the housing body 11. The shell body 21 also has a through hole 2a through which a bolt 41 of the fastening member 40 is inserted along the fitting direction X. The through hole 2a is aligned in the fitting direction X with and communicates with a through hole provided in the rear cover 12 and a central hole (see FIG. 5) provided in the housing body 11.

[0028] Further, a wire holding portion 22 (see FIG. 4) that holds the electric wire W is provided at the lower end of the shell body 21. The wire holding portion 22 has a substantially U-shaped cross section that opens toward the other side in the fitting direction X, and the electric wire W is routed inside the wire holding portion 22 along the height direction Z. Here, the shell body 21 is provided with four wire holding portions 22 aligned in the width direction Y, and the electric wire W is inserted into each of the four wire holding portions 22.

[0029] The lower shell 25 is a part that fixes the housing body 11 to the shield shell 20 by being fastened to the shell body 21 with fasteners 70 or the like. The lower shell 25 is positioned on the other side of the housing body 11 in the fitting direction X (the side opposite to the shell body 21). The lower shell 25 is fixed to the shell body 21 by fastening two fasteners 70 in a state in which the wire insertion portion 15 of the housing body 11 is sandwiched between the lower shell 25 and the shell body 21 in the fitting direction X.

[0030] 5 is a cross-sectional view of the connector 1. As shown in FIG. 5, the fastening member 40 is a member for fixing the connector 1 to the fixed wall surface 103a of the mating device 100. The fastening member 40 includes, for example, a bolt 41 and a waterproof washer 42. The bolt 41 has a shaft portion 41b extending along the mating direction X and a head portion 41a provided at one end of the shaft portion 41b in the mating direction X and having a larger diameter than the shaft portion 41b. The head portion 41a has, for example, a hexagonal shape when viewed from the mating direction X. The head portion 41a is engaged with the peripheral edge of the through-hole 2a on one end face of the shield shell 20 in the mating direction X.

[0031] The shaft portion 41b is a portion that is inserted into the through-hole 2a of the shield shell 20, the through-hole of the rear cover 12, and the central hole of the housing main body 11 along the fitting direction X. The shaft portion 41b is formed in a cylindrical shape. A spiral threading groove is formed on the surface of the shaft portion 41b along the fitting direction X. With the shaft portion 41b inserted into the through-hole 2a or the like, the bolt 41 is threaded into the fastening hole 104 of the fixed wall surface 103a described above, thereby fastening the bolt to the fastening hole 104. In other words, the connector 1 is fixed to the fixed wall surface 103a of the mating device 100 with the bolt 41 passing through the interior of the cylindrical portion 11A along the fitting direction X. With the bolt 41 inserted into the central hole of the cylindrical portion 11A, the bolt 41 is positioned at the center between the two inner terminals 3 of the four terminals 3 described above.

[0032] The waterproof washer 42 has, for example, a washer body 42a and a waterproof rubber 42b. The washer body 42a is a member interposed between the head 41a of the bolt 41 and the periphery of the through-hole 2a on one end face of the shield shell 20 in the fitting direction X. The washer body 42a is formed in an annular (ring-like) shape. The washer body 42a has the function of suppressing interference between the head 41a of the bolt 41 and the shield shell 20.

[0033] The watertight rubber 42b prevents moisture and the like from entering the through-hole 2a through an annular gap between the washer body 42a and the head 41a of the bolt 41. The watertight rubber 42b is made of an elastically deformable material such as rubber. The watertight rubber 42b is interposed between the inner surface of the washer body 42a and the shank 41b of the bolt 41. The watertight rubber 42b is formed in an annular (ring-like) shape along the inner surface of the washer body 42a. In this embodiment, a waterproof washer 42 is also provided on the other end face of the rear cover 12 in the fitting direction X. That is, the fastening member 40 is provided with a pair of waterproof washers 42 spaced apart from each other in the fitting direction X.

[0034] In this embodiment, a seal member 50 is provided on the shaft portion 41b of the bolt 41 adjacent to the watertight rubber 42b in the fitting direction X. The seal member 50 prevents moisture and other contaminants from entering the connector 1 through an annular gap between the outer circumferential surface of the shaft portion 41b and the inner surface of the through-hole 2a. The seal member 50 is made of an elastically deformable material such as rubber or resin. The seal member 50 is interposed, for example, between the outer circumferential surface of the shaft portion 41b and the inner surface of the through-hole 2a, and between the outer circumferential surface of the shaft portion 41b and the inner surface of the through-hole in the rear cover 12. The seal member 50 is formed, for example, in a cylindrical shape that conforms to the outer circumferential surface of the shaft portion 41b and is fitted to the outer circumferential surface of the shaft portion 41b. The seal member 50 is also referred to as a bushing or the like.

[0035] In this embodiment, a packing 60 is provided between the housing main body 11 and the rear cover 12. The packing 60 prevents foreign matter such as moisture and dust from entering the inside of the connector 1 through an annular gap between the housing main body 11 and the rear cover 12 (shield shell 20). The packing 60 is made of an elastically deformable material such as rubber or resin. The packing 60 is formed, for example, in an annular shape along the outer peripheral surface of the rear cover 12 and is fitted to the outer peripheral surface of the rear cover 12. When the rear cover 12 is integrated with the housing main body 11, the packing 60 is interposed between one end of the housing main body 11 in the fitting direction X and the outer peripheral surface of the rear cover 12. In this embodiment, the fastening member 40 is provided inside the waterproof area defined by the two packings 30 and 60.

[0036] Next, a description will be given of the operation of fitting the connector 1 having the above configuration into the mating connector 110 (see FIG. 1) and fixing it to the fixed wall surface 103a of the mating device 100. First, the worker inserts the bolt 41 of the fastening member 40 through the through hole 2a of the shield shell 20 of the connector 1, the through hole of the rear cover 12, and the central hole of the housing main body 11, and then inserts the bolt 41 into the fastening hole 104 of the fixed wall surface 103a and screws it in.

[0037] At this time, the bolt 41 of the connector 1 penetrates the center of the tubular portion 11A along the mating direction X, thereby suppressing tilt of the connector 1 with respect to the fixed wall surface 103a. Then, the worker further tightens the bolt 41, thereby mating the tubular portion 11A with the mating connector 110 and connecting the terminals 3 with the terminals of the mating connector 110. In this way, the bolt 41 of the fastening member 40 functions as an assist bolt when mating the tubular portion 11A with the mating connector 110.

[0038] In conventional connectors, the bolt 41 is provided outside the cylindrical portion 11A, i.e., at a position away from the center of the cylindrical portion 11A, which may cause the connector 1 to tilt relative to the fixed wall surface 103a when the bolt 41 is tightened. In this regard, according to the present embodiment, the bolt 41 penetrates the center of the cylindrical portion 11A along the fitting direction X, which prevents the connector 1 from tilting relative to the fixed wall surface 103a when the bolt 41 is tightened. This prevents the terminals 3 from coming into contact with the terminals of the mating connector 110 in an inclined state, which may cause prying or the like between the two terminals 3.

[0039] As described above, the connector 1 and wire harness WH of this embodiment include: a casing 2 having a cylindrical portion 11A that holds the terminal 3 provided at the end of the electric wire W therein and that is mated with a mating connector 110 of a mating device 100 (connection target) along a mating direction X; a gasket 30 that seals the annular space between the outer surface of the cylindrical portion 11A and the mating connector 110; a fastening member 40 that is attached so as to penetrate the inside of the cylindrical portion 11A along the mating direction X from a through hole 2a formed on one end surface of the casing 2 along the mating direction X, and is fixed to a fixed wall surface 103a of the mating device 100 when the cylindrical portion 11A and the mating connector 110 are mated; and a sealing member 50 that seals the annular gap between the outer surface of the fastening member 40 and the inner surface of the through hole 2a. With this configuration, the connector 1 and the wire harness WH can have the fastening member 40 provided inside the cylindrical portion 11A by the sealing member 50, that is, inside the waterproof area provided by the packing 30. As a result, the connector 1 and the wire harness WH can prevent the casing 2 from becoming large, and thus the casing 2 can be made smaller.

[0040] Furthermore, in the connector 1 and wire harness WH of this embodiment, the fastening member 40 is configured to include a bolt 41 inserted into the through hole 2a, an annular washer body 42a interposed between the head 41a of the bolt 41 and the periphery of the through hole 2a, and a waterproof washer 42 having an annular water-stopping rubber 42b interposed between the inner surface of the washer body 42a and the shank 41b of the bolt 41 and adjacent to the sealing member 50 in the fitting direction X. With this configuration, the connector 1 and wire harness WH can, for example, further prevent water from entering the inside of the casing 2 from the through hole 2a, i.e., inside the waterproof region waterproofed by the packing 30, by the waterproof washer 42 of the fastening member 40.

[0041] Furthermore, in the connector 1 and wire harness WH of this embodiment, the electric wires W are drawn out along a height direction Z that intersects with the fitting direction X with respect to the casing 2. This configuration allows the connector 1 and the wire harness WH to be configured more simply, and in turn makes it possible to provide, for example, a fastening member 40 that can be relatively easily inserted into the through hole 2a on one end face of the casing 2 in the fitting direction X, and a sealing member 50 that seals a gap between the outer peripheral surface of the fastening member 40 and the inner surface of the through hole 2a.

[0042] In the present embodiment, the electric wires W are drawn out along the height direction Z intersecting the fitting direction X with respect to the casing 2, but the present invention is not limited to this example. For example, the electric wires W may be drawn out along the fitting direction X with respect to the casing 2, or along the width direction Y. In addition, in the present embodiment, the casing 2 is formed by combining a plurality of parts including the housing 10 and the shield shell 20, but the present invention is not limited to this example. For example, the casing 2 may be formed by a single part. In addition, the packing 60 may be provided between the housing 10 and the shield shell 20, for example.

[0043] 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.
