[0003] [Patent Document 1] JP 2021-136137 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the connector described in Patent Document 1 mentioned above, if water accumulates near the waterproof interface between the grommet and the housing, there is a risk of corrosion products being generated in this area, so it is desirable to make it difficult for water to accumulate in this area.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a shielded connector and a wire harness that can prevent water from accumulating near the waterproof interface between the grommet and the housing. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the shielded connector of the present invention comprises: an insulating housing having a cylindrical portion that holds a terminal provided at an end of an electric wire and a protrusion that protrudes radially outward from the cylindrical portion; a shield shell having a shell main body portion formed in a cylindrical shape from a conductive metal and accommodating the cylindrical portion inside; and a flange portion that protrudes radially outward from the shell main body portion and is positioned adjacent to the protrusion in the axial direction of the electric wire; an insulating grommet formed in a cylindrical shape along the outer peripheral surface of the shell main body, accommodating the shell main body inside and being positioned adjacent to the flange portion in the axial direction; and a drainage guide portion provided on the flange portion, inclined with respect to an upper end surface of the grommet or an upper end surface of the protrusion, and guiding water to at least one side of the grommet in a width direction intersecting the axial direction. Effect of the Invention

[0007] In the shielded connector and wire harness according to the present invention, a drainage guide portion is provided on a flange portion of a shielded shell located between the grommet and a protruding portion of a housing in the axial direction, the drainage guide portion being inclined with respect to an upper end surface of the grommet or an upper end surface of the protruding portion and guiding water to at least one side in a width direction of the grommet intersecting with the axial direction. With this configuration, when the vicinity of the waterproof interface between the grommet and the housing of the shielded connector and wire harness becomes wet, the drainage guide portion can guide the water to at least one side in the width direction of the grommet and discharge the water. As a result, the shielded connector and wire harness have an effect of making it difficult for water to accumulate near the waterproof interface between the grommet and the housing.

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 a perspective view of a shielded connector 100 applied to a wire harness WH according to an embodiment, and Fig. 2 is an exploded perspective view of the shielded connector 100. The shielded connector 100 of this embodiment shown in Figs. 1 and 2 is incorporated into a wire harness WH arranged in a vehicle such as an automobile. Here, the wire harness WH is, for example, an assembly part in which a plurality of electric wires 10 used for power supply and signal communication are bundled together to connect each device mounted on the vehicle, and the plurality of electric wires 10 are connected to each device by the shielded connector 100 or the like.

[0011] The wire harness WH includes, for example, a plurality of conductive electric wires 10 each having a terminal 11 at its end, and a shield connector 100 provided at the end of the electric wires 10. In this case, the shield connector 100 is provided at the end of two electric wires 10 and holds the terminals 11 of the two electric wires 10. The wire harness WH may further include a protector, a fixing device, and the like.

[0012] 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 "height direction Z". Here, the axial direction X, the width direction Y, and the height direction Z are approximately perpendicular to each other. The axial direction X typically corresponds to the extension direction of the shield connector 100, the insertion direction of the electric wire 10 into the shield connector 100, the extension direction of the electric wire 10 inserted into the shield connector 100, and the like. The width direction Y typically corresponds to the width direction (left-right direction, side) of the shield connector 100. The height direction Z corresponds to the intersecting direction (up-down direction) that intersects with the axial direction X and the width direction Y. In addition, each direction used in the following description will be described as a direction in a state in which the electric wire 10 is assembled to the shield connector 100, unless otherwise specified.

[0013] As shown in Fig. 2, the electric wire 10 includes, for example, a linear conductor portion 10a having electrical conductivity, and an insulating covering portion 10b having electrical insulation and covering the outside of the conductor portion 10a. The electric wire 10 is an insulated electric wire in which the conductor portion 10a is covered with the insulating covering portion 10b. The conductor portion 10a 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 covering portion 10b is an electric wire covering the outer periphery of the conductor portion 10a. The insulating covering portion 10b 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.).

[0014] The terminal 11 is provided at an end of the electric wire 10. Specifically, at least one end of the electric wire 10 has the insulating coating portion 10b stripped off to expose the conductor portion 10a, and the terminal 11 is crimped to the exposed conductor portion 10a. The terminal 11 is formed in a flat plate shape from a conductive metal such as copper. The terminal 11 includes an electrical connection portion 11a that is connected to a terminal (not shown) of the mating unit 200 (see FIG. 3), and an electric wire crimping portion 11b that is connected to the conductor portion 10a of the electric wire 10. The terminal 11 is also called a crimp terminal or the like.

[0015] The shielded connector 100 includes, for example, a housing 20, a shield shell 30, a front holder 40, a rear holder 50, a packing 60, a rubber plug 70, and a grommet 80. The shielded connector 100 is used in, for example, a wire harness WH having an electric power supply wire 10 that supplies power from an inverter to a motor in a vehicle such as a hybrid vehicle or an electric vehicle. The shielded connector 100 holds a terminal 11 provided at an end of the electric power wire 10, and is connected to a terminal of a mating unit 200 (see FIG. 3 ), thereby electrically connecting the electric power wire 10 and the mating unit 200 via the terminal 11.

[0016] The housing 20 holds the terminals 11 of the two electric wires 10 arranged side by side in the width direction Y, and is made of an insulating synthetic resin material. The housing 20 has, for example, a cylindrical portion 21 that holds the two terminals 11, and a protruding portion 22 that protrudes radially outward from the cylindrical portion 21. The housing 20 has the cylindrical portion 21 and the protruding portion 22 integrally formed, and is provided therein with two terminal accommodating portions 23 that accommodate the terminals 11. The terminal accommodating portions 23 extend in the axial direction X along the terminals 11, and are partitioned from each other in the width direction Y.

[0017] The protruding portion 22 is provided at approximately the center of the cylindrical portion 21 in the axial direction X, and is formed in an annular shape along the outer circumferential surface of the cylindrical portion 21 as a whole. The housing 20 is provided with an annular packing accommodating space 24 between the cylindrical portion 21 and the protruding portion 22. The packing accommodating space 24 is a space into which the packing 60 is inserted, and is provided on the front holder 40 side of the protruding portion 22 in the axial direction X.

[0018] The packing 60 is formed to be elastically deformable, for example, from synthetic rubber having elasticity. The packing 60 is formed in an annular shape on a plane intersecting at a right angle with the axial direction X. The packing 60 is inserted into the above-mentioned packing accommodating space 24, and is sandwiched between the front holder 40 and the housing 20 in the axial direction X. For example, when the shielded connector 100 is attached to the mating unit 200 (see FIG. 3), the packing 60 elastically adheres to an inner circumferential surface of a cylindrical insertion portion 202 (opening) of the mating unit 200, thereby preventing moisture and the like from entering between the shielded connector 100 and the insertion portion 202.

[0019] The front holder 40 prevents the terminals 11 held in the housing 20 from coming off the housing 20. The front holder 40 also functions as a member for holding the packing 60 between the housing 20 and the front holder 40. The front holder 40 has, for example, a cylindrical peripheral wall portion 41 and a middle wall portion 42 extending between the inner peripheral surface of the peripheral wall portion 41, and the peripheral wall portion 41 and the middle wall portion 42 are integrally formed. The middle wall portion 42 has two openings 43 through which the terminals 11 penetrate in the axial direction X. The front holder 40 is integrated with the housing 20 by, for example, claw engagement or the like in a state in which the open end of the terminal accommodating portion 23 in the axial direction X is blocked by the middle wall portion 42.

[0020] The rear holder 50 holds the two electric wires 10 together with the housing 20. The rear holder 50 also functions as a member for holding the rubber plug 70 between the housing 20. The rear holder 50 has, for example, two parts 51 and 52 divided into two in the height direction Z, and is configured to be able to hold the electric wires 10 between the two parts 51 and 52. The rear holder 50 is integrated with the housing 20 by, for example, claw engagement or the like.

[0021] The rubber plug 70 is formed of, for example, synthetic rubber having elasticity so as to be elastically deformable. The shielded connector 100 has, for example, two rubber plugs 70. The rubber plug 70 is formed in a cylindrical shape and is provided with a through hole 71 through which the electric wire 10 passes in the axial direction X. The rubber plug 70 is disposed between the outer peripheral surface of the electric wire 10 and the inner peripheral surface of the tubular portion 21 of the housing 20 in the radial direction of the electric wire 10. The rubber plug 70 is attached between the electric wire 10 and the tubular portion 21 in a compressed state, thereby making it possible to suppress the intrusion of moisture and the like from between the electric wire 10 and the tubular portion 21 to the terminal accommodating portion 23 side.

[0022] The grommet 80 is formed in a substantially cylindrical shape along the axial direction X by, for example, synthetic rubber having elasticity. The grommet 80 has, for example, a large diameter portion 81 that houses the shell main body 31 of the shield shell 30 inside, a small diameter portion 82 from which the electric wire 10 is drawn in the axial direction X, and a reduced diameter portion 83 that spans between the large diameter portion 81 and the small diameter portion 82, and the large diameter portion 81, the small diameter portion 82, and the reduced diameter portion 83 are integrally formed. The large diameter portion 81 is formed in a substantially elliptical cylindrical shape that is horizontally elongated in the width direction Y along the outer circumferential surface 31a of the shell main body 31. The reduced diameter portion 83 is gradually reduced in radial size from the large diameter portion 81 to the small diameter portion 82 in the axial direction X, and is formed in, for example, a bellows shape that can expand and contract in the axial direction X. The small diameter portion 82 is formed in a cylindrical shape centered on the central axis of the grommet 80. The grommet 80 is fixed to the outer peripheral surface 31a of the shell main body 31 by, for example, a cable tie or the like.

[0023] The shield shell 30 is formed in a substantially cylindrical shape along the axial direction X from a conductive metal such as aluminum or an aluminum alloy. The shield shell 30, for example, accommodates inside a portion of the cylindrical portion 21 of the housing 20 that is closer to the rear holder 50 in the axial direction X than the protruding portion 22, thereby suppressing leakage of noise generated from the electric wires 10 to the outside of the shield shell 30. The shield shell 30 has, for example, a shell main body portion 31, a flange portion 33, and a fastening portion 34, and the shell main body portion 31, the flange portion 33, and the fastening portion 34 are integrally formed.

[0024] The shell body 31 is a portion of the shield shell 30 into which the cylindrical portion 21 of the housing 20 is inserted. The shell body 31 is formed, for example, in a generally elliptical cylindrical shape elongated in the width direction Y along the outer peripheral surface of the cylindrical portion 21 of the housing 20 and the inner peripheral surface of the large diameter portion 81 of the grommet 80. The shell body 31 is integrated with the cylindrical portion 21 and the large diameter portion 81 by claw fitting, press fitting, or the like. The shell body 31 functions as a portion where an end of a braided body serving as a shielding member (not shown) covering the electric wire 10 is crimped via a crimping ring or the like to be electrically connected. The shell body 31 is fixed to the housing 201 of the mating unit 200 via the fastening portion 34 and the bolt 38 (see FIG. 3 ) and is grounded via the housing 201 of the mating unit 200. As a result, the shield shell 30 and the braided body function as a shield.

[0025] 3 is a perspective view of the shielded connector 100 according to the embodiment, and shows a state where the shielded connector 100 is attached to the mating unit 200. As shown in FIG. 3, the flange portion 33 is a portion of the shielded shell 30 that protrudes from the shell main body 31 radially outward of the shell main body 31. When viewed from the axial direction X, the flange portion 33 is formed, for example, in a substantially rectangular plate shape that is horizontally elongated in the width direction Y. The flange portion 33 is provided on the housing 20 side of the shell main body 31 in the axial direction X, that is, at one end opposite to the grommet 80. The flange portion 33 abuts against the protruding portion 22 of the housing 20 and the open end surface 80a of the grommet 80, and is positioned adjacent to the axial direction X.

[0026] The fastening portion 34 is a portion of the shield shell 30 that protrudes from the flange portion 33 along the axial direction X. The fastening portion 34 is provided, for example, on an upper end surface 33a of the flange portion 33 on one side in the height direction Z. Specifically, in this embodiment, the fastening portion 34 is provided in a pair at both ends in the width direction Y of the upper end surface 33a. The fastening portions 34 protrude from the flange portion 33 toward the housing 20 along the axial direction X and are overlapped with the mounting portion 203 of the mating unit 200 in the height direction Z. The fastening portions 34 are provided with mounting holes 34a (see FIG. 2) to which the bolts 38 are fastened together with the mounting portions 203. The mounting holes 34a are through holes that penetrate the fastening portion 34 in the height direction Z and have an opening width smaller than that of the head portion 38a of the bolt 38.

[0027] Here, in this embodiment, the flange portion 33 is provided with a drainage guide portion 35 adjacent to the grommet 80 and the protruding portion 22 of the housing 20. The drainage guide portion 35 is intended to prevent water from accumulating near the waterproof interface between the grommet 80 and the protruding portion 22 of the housing 20. Specifically, the drainage guide portion 35 is inclined with respect to an upper end surface 80b on one side of the grommet 80 in the height direction Z and an upper end surface 22a on one side of the protruding portion 22 in the height direction Z. The drainage guide portion 35 has a function of guiding water to at least one side of the grommet 80 in the width direction Y when the vicinity of the waterproof interface between the grommet 80 and the protruding portion 22 of the housing 20 is wetted with water.

[0028] Specifically, the drainage guide portion 35 includes, for example, an inclined surface 36 and a groove portion 37. The inclined surface 36 is a portion of the drainage guide portion 35 that constitutes the first drainage passage 35a on the upstream side. The inclined surface 36 is provided on the upper end surface 33a on one side in the height direction Z of the flange portion 33. The inclined surface 36 is gradually inclined toward the other side in the height direction Z, i.e., downward, toward both ends in the width direction Y of the upper end surface 33a. In this embodiment, the inclined surface 36 is formed in a V-shape with the central portion 33c in the width direction Y of the upper end surface 33a as the apex. Both ends 36b of the inclined surface 36 in the width direction Y extend to approximately the same positions as both ends of the grommet 80 in the width direction Y.

[0029] The first drainage passage 35a of the drainage guide portion 35 is not limited to this example, and may have, for example, a standing wall (rib) or the like protruding to one side in the height direction Z on both sides of the axial direction X of the inclined surface 36. This can further suppress the intrusion of water from the approximately elliptical gap between the flange portion 33 and the grommet 80, the approximately elliptical gap between the flange portion 33 and the protruding portion 22, and the like. In this embodiment, the central portion 36a (top portion) of the inclined surface 36 in the width direction Y protrudes to one side in the height direction Z beyond the upper end surface 80b of the grommet 80 and the upper end surface 22a of the protruding portion 22. In addition, the positions of both ends 36b of the inclined surface 36 in the width direction Y are approximately the same as the positions of the upper end surface 80b of the grommet 80 and the upper end surface 22a of the protruding portion 22 in the height direction Z.

[0030] The groove portion 37 is a portion constituting the downstream second drain passage 35b of the drain guide portion 35. The groove portion 37 is provided on the front surface 33b exposed to the outside of the grommet 80 on one side in the axial direction X of the flange portion 33. The front surface 33b is also referred to as a side surface or the like. The groove portion 37 is recessed from the front surface 33b toward the other side in the axial direction X (the housing 20 side) and is a recess that is open to the one side in the axial direction X (the grommet 80 side). The groove portion 37 is provided in pairs on both sides of the width direction Y of the front surface 33b sandwiching the grommet 80 therebetween. The groove portion 37 is gradually inclined toward the other side in the height direction Z, i.e., downward, as it approaches both sides in the width direction Y.

[0031] In this embodiment, two grooves 37 are provided side by side in the height direction Z on both sides of the grommet 80 in the width direction Y of the front surface 33b. The groove 37 on one side in the height direction Z has one end 37a (upper end) in the inclination direction opening to the upper end surface 33a of the flange portion 33 and communicating with the first drainage passage 35a to function as a water inlet, and the other end 37b (lower end) in the inclination direction opening to both ends of the front surface 33b in the width direction Y to function as a water outlet. On the other hand, the groove 37 on the other side in the height direction Z has one end 37a (upper end) in the inclination direction opening to the end on the center side of the front surface 33b in the width direction Y to function as an inlet for water flowing down along the open end surface 80a of the grommet 80, and the other end 37b (lower end) in the inclination direction opening to both ends of the front surface 33b in the width direction Y to function as a water outlet.

[0032] 4 is an explanatory diagram for explaining a drainage method by the drainage guide portion 35 of the shielded connector 100 according to the embodiment. As shown in FIG. 4, in this embodiment, when the vicinity of the waterproof interface between the grommet 80 and the protruding portion 22 of the housing 20 is wetted with water, the V-shaped inclined surface 36 (first drainage passage 35a) of the drainage guide portion 35 guides the water to both ends 36b of the inclined surface 36 in the width direction Y. Then, the water passes through the upper end surface 33a of the flange portion 33 and is introduced from one end 37a into the groove portion 37 (second drainage passage 35b) on one side in the height direction Z, flows down along the inclination direction, and is discharged from the other end 37b of the groove portion 37 to both sides in the width direction Y.

[0033] At this time, a portion of the water that has not been introduced into the groove portion 37 on one side in the height direction Z flows down along the open end face 80a of the grommet 80 and is introduced into the groove portion 37 (second drainage passage 35b) on the other side in the height direction Z. The water then flows down the groove portion 37 along the inclination direction from one end 37a to the other end 37b and is discharged to both sides in the width direction Y of the flange portion 33. Note that the number of groove portions 37 is not limited to this example, and for example, three or more groove portions 37 may be provided at intervals from each other in the height direction Z on both sides of the grommet 80 on the front surface 33b in the width direction Y.

[0034] As described above, in the shielded connector 100 and the wire harness WH of the present embodiment, the flange portion 33 of the shield shell 30 located between the grommet 80 and the protruding portion 22 of the housing 20 in the axial direction X is provided with the drainage guide portion 35 that is inclined with respect to the upper end surface 80b of the grommet 80 or the upper end surface 22a of the protruding portion 22 and guides water to at least one side of the grommet 80 in the width direction Y intersecting with the axial direction X. With this configuration, when the vicinity of the waterproof interface between the grommet 80 and the housing 20 is wetted with water, the shielded connector 100 and the wire harness WH can guide the water to at least one side of the grommet 80 in the width direction Y by the drainage guide portion 35 and discharge the water. As a result, the shielded connector 100 and the wire harness WH can make it difficult for water to accumulate near the waterproof interface between the grommet 80 and the housing 20, and thus can suppress the generation of corrosion products near the waterproof interface between the grommet 80 and the housing 20, and can suppress the influence of the corrosion products on the shielded connector 100 and the wire harness WH.

[0035] In the shielded connector 100 and the wire harness WH of this embodiment, the drainage guide portion 35 is provided on the upper end surface 33a of the flange portion 33 and has an inclined surface 36 that constitutes the first drainage passage 35a of the drainage guide portion 35. With this configuration, when the vicinity of the waterproof interface between the grommet 80 and the housing 20 becomes wet, the shielded connector 100 and the wire harness WH can guide the water to at least one side in the width direction Y of the grommet 80 by the inclined surface 36 provided on the upper end surface 33a of the flange portion 33 and discharge the water.

[0036] In the shielded connector 100 and the wire harness WH of this embodiment, the inclined surface 36 is formed in a V-shape with the central portion 33c of the upper end surface 33a in the width direction Y as the apex. With this configuration, when the vicinity of the waterproof interface between the grommet 80 and the housing 20 becomes wet, the shielded connector 100 and the wire harness WH can guide the water to both sides of the grommet 80 in the width direction Y by the V-shaped inclined surface 36 provided on the upper end surface 33a of the flange portion 33 and discharge the water.

[0037] In the shielded connector 100 and the wire harness WH of this embodiment, the drainage guide portion 35 is provided on the front surface 33b exposed to the outside of the grommet 80 on one side in the axial direction X of the flange portion 33, and has a groove portion 37 recessed along the axial direction X to form a second drainage passage 35b of the drainage guide portion 35. With this configuration, when the vicinity of the waterproof interface between the grommet 80 and the housing 20 becomes wet, the shielded connector 100 and the wire harness WH can further guide and discharge water guided by the inclined surface 36 to at least one side in the width direction Y of the grommet 80 away from the grommet 80 by the groove portion 37 provided on the front surface 33b.

[0038] 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.
