DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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 the same. Note that in this specification, ordinal numbers are used only to distinguish between parts, members, parts, positions, directions, etc., and do not indicate order or priority.

[0010] [Embodiment] FIG. 1 is an exploded perspective view of a connector 1 according to an embodiment. The connector 1 of this embodiment shown in FIG. 1 is incorporated into a wire harness WH arranged in a vehicle such as an automobile. Here, the wire harness WH is, for example, a bundle of electric wires W used for power supply and signal communication to connect each device mounted on a vehicle, and the electric wires W are connected to each device by 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 terminals of the plurality of electric wires W. The wire harness WH may further include a protector, a fixing device, and the like.

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

[0012] The electric wire W includes, for example, a linear conductor portion W1 (see FIG. 6) having electrical conductivity, and an insulating coating W2 having electrical insulation that covers the outside of the conductor portion W1. The electric wire W is an insulated electric wire in which the conductor portion W1 is coated with the insulating coating W2. The conductor portion W1 in this embodiment is a core wire in which a plurality of conductive metal wires are bundled together, but may be a twisted core wire in which the plurality of metal wires are twisted together. The insulating coating W2 is an electric wire coating that coats the outer periphery of the conductor portion W1. The insulating coating W2 is formed, for example, by extrusion molding an insulating resin material (such as PP, PVC, or cross-linked PE, which is appropriately selected in consideration of abrasion resistance, chemical resistance, heat resistance, etc.).

[0013] The electric wires W are each formed to extend linearly along the axial direction X and to extend with approximately the same diameter in the axial direction X (extension direction). In addition, the electric wires W are formed, for example, such that the cross-sectional shape of the conductor portion W1 (cross-sectional shape intersecting with the axial direction X) is approximately circular and the cross-sectional shape of the insulating coating W2 is approximately annular, so that 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 off, and a terminal 3 (see FIG. 1) is crimped to the conductor portion W1 exposed from the insulating coating W2.

[0014] The terminal 3 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 3 includes, for example, an electrical connection portion electrically connected to the terminal of the mating connector, and an electric wire crimping portion electrically connected to an end of the electric wire W. The electric wire crimping portion has, for example, a pair of barrel pieces that are crimped to a conductor portion W1 of the electric wire W, and is electrically connected to the electric wire W by crimping the pair of barrel pieces and the conductor portion W1. The terminal 3 is also called a crimp terminal or the like.

[0015] 1, the connector 1 includes a casing 2 formed by combining a plurality of parts including, for example, a housing 10 and a shield shell 20, a wire packing 30 described below, and a rear holder 40. The connector 1 is used in, for example, a wire harness WH having an electric wire W for supplying power from an inverter to a motor in a vehicle such as a hybrid vehicle or an electric vehicle. The connector 1 holds a terminal 3 provided at an end of the electric wire W, and can electrically connect the electric wire W to the mating connector via the terminal 3 by mating with a mating connector (not shown).

[0016] The housing 10 is a portion of the casing 2 that holds the terminals 3 therein and is fitted with a mating connector. The housing 10 is formed by combining a plurality of parts. Specifically, the housing 10 includes, for example, a housing main body 11, an inner housing 12, a front holder 13, and a rear cover 14. The housing main body 11, the inner housing 12, the front holder 13, and the rear cover 14 are each formed from an insulating resin material.

[0017] The housing main body 11 is provided with a cylindrical portion that protrudes cylindrically toward one side in the fitting direction Z (the mating connector side) and holds the terminal 3 therein. In this embodiment, the cylindrical portion is provided with two terminals 3 spaced from each other in the width direction Y. The cylindrical portion is formed, for example, with openings on both sides in the fitting direction Z. When the terminal 3 is attached to the cylindrical portion, the terminal 3 is exposed to the outside from the opening on one side in the fitting direction Z, while the opening on the other side in the fitting direction Z is closed by the rear cover 14. The housing main body 11 is formed, for example, in a substantially rectangular shape when viewed from the fitting direction Z.

[0018] The rear cover 14 is a member for closing the opening of the cylindrical portion in the housing main body 11 from the other side in the fitting direction Z. The rear cover 14 is configured to include, for example, a cover main body that covers the opening of the housing main body 11, and a plurality of locking portions that are locked to the outer circumferential surface of the housing main body 11. With the cover main body covering the opening of the housing main body 11, the rear cover 14 is integrated with the housing main body 11 by so-called snap fit using the locking portions. In addition, a packing 17 is provided between the rear cover 14 and the housing main body 11 to prevent foreign matter such as moisture from entering the inside through an annular gap between the rear cover 14 and the housing main body 11.

[0019] The inner housing 12 is a member formed separately from the housing body 11, and is a member that receives and holds the terminals 3 along the fitting direction Z when attached to the inside of the cylindrical portion of the housing body 11. The inner housing 12 is provided with a plurality of insertion holes through which the terminals 3 are inserted along the fitting direction Z. The plurality of insertion holes are aligned in the width direction Y. In other words, the plurality of terminals 3 are held in a state where they are partitioned from one another in the width direction Y by the inner housing 12.

[0020] The front holder 13 is, for example, a member for holding the packings 15, 16 between the front holder 13 and the housing main body 11. The front holder 13 is formed in a cylindrical shape that conforms to the outer peripheral surface of the cylindrical portion of the housing main body 11, and is fitted to the outer peripheral surface of the cylindrical portion. The front holder 13 is formed in a substantially rectangular cylindrical shape, for example, when viewed from the fitting direction Z. The front holder 13 is integrated with the cylindrical portion by claw fitting or the like, with the packings 15, 16 sandwiched between the front holder 13 and the housing main body 11.

[0021] The packings 15 and 16 are intended to prevent foreign matter such as moisture from entering the inside of the connector 1 through an annular gap between the cylindrical portion of the housing main body 11 and the mating connector. The packings 15 and 16 are made of an elastically deformable material such as rubber or resin. The packings 15 and 16 are formed, for example, in a substantially rectangular cylindrical shape along the outer circumferential surface of the cylindrical portion of the housing main body 11, and are fitted to the outer circumferential surface of the cylindrical portion. The packings 15 and 16 are interposed between the housing main body 11 and the mating connector on the other side of the fitting direction Z of the front holder 13 in a fitted state in which the housing main body 11 is fitted to the mating connector.

[0022] The shield shell 20 is a part of the casing 2 that covers the terminals 3 and the electric wires W to prevent noise generated from the electric wires W from leaking outside the connector 1. As shown in Fig. 1, the shield shell 20 is formed by combining a plurality of parts. Specifically, the shield shell 20 includes, for example, an upper shell 21, a lower shell 22, and a shield ring 23. The upper shell 21, the lower shell 22, and the shield ring 23 are each formed, for example, from a metallic material having electrical conductivity.

[0023] The upper shell 21 is a portion of the shield shell 20 that covers the other side of the housing 10 in the fitting direction Z (the side opposite to the mating connector). The upper shell 21 is provided with an accommodation space that is open toward one side in the fitting direction Z and accommodates the rear cover 14 of the housing 10 and a part of the housing main body 11. The upper shell 21 also has a through hole through which a fastening member 50 that fastens the housing main body 11 and the shield shell 20 is inserted along the fitting direction Z.

[0024] The lower shell 22 is a portion of the shield shell 20 that covers the periphery of a wire packing 30, a rear holder 40, electric wires W, etc., which will be described later. The lower shell 22 is located on the other side (lower side) of the upper shell 21 in the axial direction X. The lower shell 22 is fixed to the upper shell 21 by a fastening member 50, for example, in a state in which the wire packing 30, the rear holder 40, electric wires W, etc. are housed inside. The shield ring 23 is crimped to the braid of the electric wires W, for example.

[0025] Fig. 2 is a perspective view of the wire packing 30 of the connector 1, and Fig. 3 is a cross-sectional view of the wire packing 30. As shown in Figs. 2 and 3, the wire packing 30 has, for example, an electric wire insertion hole 31 through which an electric wire W is inserted along the axial direction X, and seals the periphery of the electric wire W. In this embodiment, the wire packing 30 has two electric wire insertion holes 31 spaced apart from each other in the width direction Y. The wire packing 30 is formed of an elastically deformable member such as rubber. The wire packing 30 is also called a seal member, a rubber plug, a bush, or the like.

[0026] Here, in this embodiment, the wire packing 30 is provided with a concave hollowed-out portion 32 on an end face 30a on one side (upper side, housing body 11 side) in the axial direction X. The hollowed-out portion 32 is a recess (groove) that is recessed from the end face 30a of the wire packing 30 toward the other side in the axial direction X and is open toward the one side in the axial direction X. In this embodiment, the hollowed-out portion 32 is formed in a shape surrounding each of the multiple electric wire insertion holes 31. As a result, the wire packing 30 is provided with two inner diameter portions 33 that protrude cylindrically from the periphery of each of the electric wire insertion holes 31, and an outer diameter portion 34 that protrudes in a substantially elliptical cylindrical shape on the outer periphery side of the inner diameter portions 33.

[0027] The inner diameter portion 33 is a portion of the wire packing 30 located radially inward of the wire insertion hole 31 relative to the hollowed-out portion 32. The inner diameter portion 33 is provided with a plurality of inner circumferential lip portions and a plurality of outer circumferential lip portions. The inner circumferential lip portion and the outer circumferential lip portion are pleated water-stopping portions formed in a substantially annular shape along the inner circumferential surface and the outer circumferential surface of the inner diameter portion 33. In this embodiment, the inner diameter portion 33 is provided with two inner circumferential lip portions and two outer circumferential lip portions arranged in the axial direction X. The inner circumferential lip portions are in close contact with the outer circumferential surface of the electric wire W when the electric wire W is inserted (press-fitted) into the electric wire insertion hole 31. The inner diameter portion 33 is configured such that the outer circumferential lip portion and the inner circumferential lip portion are elastically deformed radially inward of the electric wire insertion hole 31 by the engagement between a rib 42 (see FIG. 4) described later and the hollowed-out portion 32, thereby increasing the surface pressure between the outer circumferential surface of the electric wire W.

[0028] The outer diameter portion 34 is a portion of the wire packing 30 located radially outward of the wire insertion hole 31 relative to the hollowed-out portion 32. The outer diameter portion 34 is provided with a plurality of inner peripheral lip portions and a plurality of outer peripheral lip portions, similar to the inner diameter portion 33. The inner peripheral lip portions and the outer peripheral lip portions are pleated water-stopping portions formed in a substantially annular shape along the inner peripheral surface and the outer peripheral surface of the outer diameter portion 34. In this embodiment, the outer diameter portion 34 is provided with two inner peripheral lip portions and two outer peripheral lip portions arranged in the axial direction X. The outer peripheral lip portions are in close contact with the inner peripheral surface of the lower shell 22 (see FIG. 6) when the wire packing 30 is attached inside the lower shell 22. The outer diameter portion 34 is configured so that the inner lip portion and the outer lip portion elastically deform radially outward of the wire insertion hole 31 upon engagement between the rib 42 described later and the hollowed-out portion 32, thereby increasing the surface pressure between them and the inner surface of the lower shell 22.

[0029] Fig. 4 is a perspective view of the rear holder 40 of the connector 1, and Fig. 5 is a cross-sectional view of the rear holder 40 of the connector 1. As shown in Figs. 4 and 5, the rear holder 40 is a member that is positioned, for example, on one side (upper side, housing main body 11 side) of the wire packing 30 in the axial direction X and holds the wire packing 30. The rear holder 40 is configured to include, for example, a holder main body 41 and a rib 42. The rear holder 40 is formed, for example, from a synthetic resin material or the like.

[0030] The holder body 41 is configured, for example, by two divided bodies (see FIG. 1) that can be separated from each other along the fitting direction Z. Each divided body of the holder body 41 is provided with a semicircular electric wire insertion hole 43 into which an electric wire W is inserted along the axial direction X. The holder body 41 is also provided with two electric wire insertion holes 43 spaced apart from each other in the width direction Y. The two electric wire insertion holes 43 are positioned side by side with the electric wire insertion holes 31 of the wire packing 30 in the axial direction X. The holder body 41 is also provided on its outer circumferential surface with lattice-shaped beads 44 for ensuring the rigidity and strength of the rear holder 40.

[0031] The rib 42 is a portion of the rear holder 40 that engages with the above-mentioned hollowed-out portion 32 of the wire packing 30. The rib 42 protrudes from each divided body of the holder body 41 toward the other side in the axial direction X (the wire packing 30 side). The rib 42 is formed into a shape that generally follows the outer shape of the hollowed-out portion 32 of the wire packing 30. That is, the rib 42 is configured to include a substantially elliptical outer circumferential portion that engages with a portion between the outer diameter portion 34 and the inner diameter portion 33 of the hollowed-out portion 32, and a central portion that engages with a portion between the two inner diameter portions 33 in the width direction Y.

[0032] Next, a fitting operation during the assembly work of the rear holder 40 and the wire packing 30 of the connector 1 having the above configuration will be described. Fig. 6 is a cross-sectional view showing the state before the rib 42 of the rear holder 40 and the lightening hole 32 of the wire packing 30 are engaged, Fig. 7 is a cross-sectional view showing the state during the engagement between the rib 42 of the rear holder 40 and the lightening hole 32 of the wire packing 30, and Fig. 8 is a cross-sectional view showing the state after the rib 42 of the rear holder 40 and the lightening hole 32 of the wire packing 30 are engaged.

[0033] 6, before the rib 42 of the rear holder 40 and the lightening hole 32 of the wire packing 30 engage with each other, the rib 42 does not enter the lightening hole 32, so the wire packing 30 is in contact with the electric wire W and the lower shell 22 in a predetermined mounting state. In this state, the insertion (press-fitting) of the electric wire W into the electric wire insertion hole 31 causes the inner peripheral lip portion of the inner diameter portion 33 to be slightly crushed more than in the free state, and the insertion (press-fitting) of the wire packing 30 into the lower shell 22 causes the outer peripheral lip portion of the outer diameter portion 34 to be slightly crushed more than in the free state.

[0034] 7, in a state in which the rib 42 of the rear holder 40 and the hollowed-out portion 32 of the wire packing 30 are in the middle of engaging with each other, the rib 42 has penetrated into the hollowed-out portion 32 to an intermediate position, so that the wire packing 30 is in contact with the electric wire W and the lower shell 22 with one side in the axial direction X being partially deformed. In this state, due to the insertion (press-fitting) of the rib 42 into the hollowed-out portion 32, the inner peripheral lip portion on one side in the axial direction X of the inner diameter portion 33 is crushed more than the inner peripheral lip portion on the other side in the axial direction X, and the outer peripheral lip portion on one side in the axial direction X of the outer diameter portion 34 is crushed more than the outer peripheral lip portion on the other side in the axial direction X.

[0035] 8, after the rib 42 of the rear holder 40 and the hollowed-out portion 32 of the wire packing 30 are engaged with each other, the rib 42 penetrates to the bottom (end) of the hollowed-out portion 32, so that the wire packing 30 comes into contact with the electric wire W and the lower shell 22 with the inner diameter portion 33 and the outer diameter portion 34 being entirely deformed. In this state, the two inner peripheral lip portions of the inner diameter portion 33 are crushed more than in the state of FIG. 6 by the insertion (press-fitting) of the rib 42 into the hollowed-out portion 32, and the two outer peripheral lip portions of the outer diameter portion 34 are crushed more than in the state of FIG. 6. Therefore, the surface pressure between the inner diameter portion 33 and the outer peripheral surface of the electric wire W increases, and the surface pressure between the outer diameter portion 34 and the inner peripheral surface of the lower shell 22 increases, so that the sealing performance between them can be further improved.

[0036] As described above, in the connector 1 and the wire harness WH of the present embodiment, the wire packing 30 is configured such that the inner diameter portion 33 of the wire packing 30 is pressed against the electric wire W side through the lightening portion 32 of the wire packing 30 by the engagement between the lightening portion 32 and the rib 42, and the outer diameter portion 34 of the wire packing 30 is pressed against the casing 2 side through the lightening portion 32 of the wire packing 30. With this configuration, the connector 1 and the wire harness WH can further press the inner diameter portion 33 of the wire packing 30 against the electric wire W side and the outer diameter portion 34 of the wire packing 30 against the casing 2 side by the lightening portion 32 engaging with the rib 42 in a state in which the electric wire W is inserted (pressed) into the wire packing 30, thereby improving the sealing performance. As a result, the connector 1 and the wire harness WH can improve the sealing performance of the wire packing 30.

[0037] In the connector 1 and wire harness WH of this embodiment, the wire packing 30 has a plurality of electric wire insertion holes 31, and the lightening portion 32 is formed in a shape surrounding the plurality of electric wire insertion holes 31. With this configuration, the connector 1 and the wire harness WH can be provided with, for example, an inner diameter portion 33 that is pressed against the electric wire W side and an outer diameter portion 34 that is pressed against the casing 2 side around each of the plurality of electric wire insertion holes 31 by the lightening portion 32, and thus the sealing property of the wire packing 30 can be further improved.

[0038] In the connector 1 and wire harness WH of this embodiment, the casing 2 is configured to include the shield shell 20 that covers the periphery of the electric wires W, and the outer diameter portion 34 of the wire packing 30 is pressed against the shield shell 20 by the engagement between the lightening-reduced portion 32 and the rib 42. With this configuration, the connector 1 and wire harness WH can further improve the sealing performance therebetween because, for example, the engagement between the lightening-reduced portion 32 and the rib 42 increases the surface pressure between the outer diameter portion 34 of the wire packing 30 and the metallic shield shell 20.

[0039] In the present embodiment, the case where two electric wire insertion holes 31 are provided in the wire packing 30 has been exemplified, but the present invention is not limited to this example, and for example, the wire packing 30 may be provided with one or three or more electric wire insertion holes 31. In this case, the shape of the lightening portion 32 of the wire packing 30 can be changed in various ways depending on the number of electric wire insertion holes 31, and the shape of the rib 42 of the rear holder 40 can be changed in various ways depending on the shape of the lightening portion 32 (the number of electric wire insertion holes 31).

[0040] In addition, in the present embodiment, the electric wire W is drawn out along the axial direction X intersecting the fitting direction Z with respect to the casing 2, but the present embodiment is not limited to this example, and for example, the electric wire W may be drawn out along the fitting direction Z with respect to the casing 2, or the electric wire W may be drawn out 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 embodiment is not limited to this example, and for example, the casing 2 may be formed by a single part.

[0041] Although the embodiment of the present invention has been illustrated above, the above embodiment is merely an example and is not intended to limit the scope of the invention. The above embodiment can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the gist of the invention. In addition, 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 appropriately changed and implemented.
