JP 2011-175766 A

In the grommet described in Patent Document 1, sand, dust, etc. (hereinafter referred to as "dust, etc.") may enter the collecting drainage member. If the collective drainage member is short, dust or the like may enter the body of the grommet through the collective drainage member and adhere to the terminals. On the other hand, if the collective drainage member is long, it becomes difficult for dust and the like to enter the main body of the grommet from the collective drainage member, but the space for arranging the collective drainage member in the vehicle becomes large.

Therefore, it is an object of the grommet to provide a technology that can suppress the adhesion of dust and the like to the terminal even when the drain port is short.

A wire harness according to the present disclosure includes a connector having a terminal and a housing holding the terminal, a wiring member connected to the terminal and extending from the connector, and a grommet covering the connector and the wiring member, The housing is formed with a cavity and a drainage hole which penetrates the housing in a first direction and opens to the back surface of the housing, and the grommet includes a first cover covering the back surface and a periphery of the back surface. a second cover portion, the second cover portion being provided with a drainage port opening in a direction intersecting with the first direction; into a first region where the opening of the cavity exists and a second region located closer to the drain port than the first region. The wire harness is located in the second region, and the tip of the partition is in contact with the inner surface of the first cover.

According to the present disclosure, even if the grommet has a short drain port, it is possible to suppress adhesion of dust and the like to the terminal.

[Description of Embodiments of the Present Disclosure]
First, the embodiments of the present disclosure are listed and described.

The wire harness of the present disclosure is as follows.

(1) A connector having a terminal and a housing for holding the terminal, a wiring member connected to the terminal and extending from the connector, and a grommet covering the connector and the wiring member, wherein the housing includes: The grommet includes a first cover portion covering the back surface and a second cover portion covering the periphery of the back surface. and the second cover portion is provided with a drainage port that opens in a direction crossing the first direction, and the housing protrudes in the first direction from the back surface and extends the back surface of the cavity. A partition is provided to separate a first region having an opening from a second region located closer to the drain port than the first region, and the opening of the drain hole is located in the second region on the back surface. and the tip of the partition is in contact with the inner surface of the first cover. Since the tip of the partition in the first direction is in contact with the inner surface of the grommet, even if dust or the like enters the grommet from the drain port, the dust or the like does not easily reach the space including the first region. As a result, even if the grommet has a short drain port, it is possible to prevent dust from adhering to the terminal. In addition, since the opening of the drain hole is located in the second region on the back surface, water entering the grommet through the drain hole easily reaches the drain port.

(2) In the wire harness of (1), the first covering portion is provided with a thick portion that is partially thick, and the inner surface of the thick portion is in contact with the tip portion of the partition. may be As a result, the thick portion of the grommet tends to receive the force from the partition appropriately, and the grommet and the partition can easily be kept in an appropriate contact state.

(3) In the wire harness of (1) or (2), the tip surface of the tip portion of the partition may be in surface contact with the inner surface of the first cover portion. As a result, the grommet and the partition are likely to be kept in proper contact with each other.

(4) In the wire harness according to any one of (1) to (3), the partition is positioned closer to the one side than the other side of the partition so that the one side of the partition is closer to the drain port than the other side of the partition. At least a portion between the partition and the other side portion is inclined, and the space including the first region and the space including the second region are in communication on the side of the one side portion of the partition. good. Thereby, when the wire harness is arranged so that the drain port faces the vertical direction, water that has entered the space including the first area from the cavity can reach the space including the second area along the partition.

(5) In the wire harness according to any one of (1) to (4), the side portion of the partition may not be in contact with the inner peripheral surface of the second cover portion of the grommet. Thereby, the gap between the grommet and the partition can be used to allow water in the space containing the first region to escape to the space containing the second region.

(6) In the wire harness according to any one of (1) to (5), the housing has a body portion and a retainer that are adjacent to each other along the first direction, and the body portion is fitted with the mating connector. Alternatively, the back surface and the partition may be provided on the retainer. Accordingly, even if the partition is changed according to the extending direction of the wiring member, it can be dealt with by changing the retainer.

(7) In the wire harness according to any one of (1) to (6), the wiring member extends from the grommet in a direction intersecting with the first direction, and extends from the second cover portion of the grommet. A lead-out port for the wiring member may be formed in a portion other than the portion in which the drain port is formed. As a result, compared to the case where the wiring member extends from the grommet in the first direction, even if the load of the wiring member is applied to the grommet, the load is less likely to act in the direction of separating the contacting portions of the partition and the grommet. It is easy to keep the inner surface of the grommet and the partition in contact with each other. Also, the height of the portion where the grommet is attached to the connector can be reduced.

(8) In the wire harness of (7), the wiring member has a power line through which a charging current flows, the terminal has a first terminal connected to the power line, and the first terminal is It has a connector terminal connected to a terminal of a mating connector, and a relay terminal connected to the connector terminal and the power line, the connector terminal being housed in the cavity, and the relay terminal being provided on the back surface. A portion of the relay terminal connected to the power line may extend in a direction in which the power line extends from the grommet. Thereby, even when the power line extends from the grommet in the direction intersecting the first direction, the power line can extend out from the grommet without bending as much as possible inside the grommet.

(9) In the wire harness of (8), the wiring member may have a signal line, and the terminal may have a second terminal connected to the signal line. As a result, adhesion of dust or the like to the second terminal for the signal line can also be suppressed.

(10) In the wire harness according to any one of (1) to (9), the partition is the first partition, and the rear surface of the housing is provided with a wire in the first direction from a position different from the first partition. A second partition is provided that protrudes and surrounds a portion of the terminal that is arranged on the back surface, and the second partition has a projecting dimension along the first direction from the back surface that extends from the back surface in the first direction. It may have a portion smaller than the projecting dimension of the first partition along the direction. This makes it difficult for the second partition to come into contact with the grommet, so that the first partition separating the first region and the second region is likely to be kept in contact with the grommet.

FIG. 2 is a plan view showing the wire harness 10 according to the first embodiment. FIG. 3 is a side view showing the wire harness 10 according to Embodiment 1. FIG. FIG. 4 is a cross-sectional view taken along line IV-IV of FIG.

<Wire harness>
The wire harness 10 includes connectors 20 , wiring members 50 and grommets 60 . The connector 20 has a housing 21 and terminals 40 . Terminals 40 are held in housing 21 . Wiring member 50 is connected to terminal 40 and extends outward from connector 20 . Grommet 60 covers connector 20 and wiring member 50 . In this example, an example in which the connector 20 is the inlet 20 will be described. The connector 20 need not be the inlet 20 and may be any connector mounted on the vehicle.

A wire harness 10 having an inlet 20 is incorporated into a vehicle. The vehicle is an electric vehicle that includes a power storage device and a motor. The vehicle runs by driving the motor with the electric power of the power storage device. The vehicle may be an electric vehicle having only a motor as a drive source, or a hybrid vehicle having a motor and an engine. A power storage device in a vehicle is charged with power supplied from an external charging station. The inlet 20 in the wire harness 10 is attached to, for example, an inlet attachment portion 80 provided on the outer surface of the body of the vehicle. An example of the inlet attachment portion 80 is shown in FIG. The inlet attachment portion 80 is formed, for example, in a concave shape in which a portion of a panel 82 forming the body is concave inside the vehicle. A through hole 84 is formed in the bottom panel 82 of the inlet mounting portion 80 . A part of the wire harness 10 is arranged inside the vehicle from the panel 82 , and the other part passes through the through hole 84 .

The inlet 20 is configured so that an external charging connector can be inserted and electrically connected. An external charging connector is, for example, a connector of a charging cable extending from a charging stand. A connecting portion with an external charging connector is provided on the front side of the inlet 20 . The connecting portion includes a portion into which an external charging connector is inserted and electrically connected. A portion of the connecting portion passes through the through hole 84 of the panel 82 . Front side portions of the housing 21 and the terminals 40 are used as connection portions. Wiring member 50 extends from inlet 20 . The wiring member 50 sends electric power from the charging station toward the power storage device of the vehicle. The grommet 60 partially covers the inlet 20 and the wiring member 50 . The grommet 60 protects the inlet 20 and the wiring member 50 and stops water from the inlet 20 in the interior space of the vehicle rather than the panel 82 . The grommet 60 is formed with a connection port 67 , an outlet port 70 and a drain port 73 . A connection portion of the inlet 20 extends out of the grommet 60 through the connection port 67 . The wiring member 50 extends out of the grommet 60 through the outlet 70 . Water in the grommet 60 is discharged outside the grommet 60 through the drain port 73 .

In the present disclosure, as shown in FIG. 2, of the X, Y, and Z directions that are orthogonal to each other, the X direction is parallel to the direction in which the inlet 20 penetrates the through hole 84 of the panel 82. . The inlet 20 and the external charging connector are connected in the X direction. The Z direction is, for example, the vertical direction. For example, when the inlet 20 is provided on the side of the vehicle, the Y direction is the longitudinal direction of the vehicle. For example, when the inlet 20 is provided on the front or rear surface of the vehicle, the Y direction is the width direction of the vehicle. Further, in the grommet 60, the connection port 67 opens in the X direction, the extraction port 70 opens in the Y direction, and the drain port 73 opens in the Z direction. Members that are not in the attached state will also be described using directions that correspond to the X, Y, and Z directions when they are in the attached state.

<Inlet and wiring member>
The inlet 20 and the wiring member 50 will be described with reference to FIGS. 5 to 6 in addition to FIGS. 1 to 4. FIG. FIG. 5 is a rear view showing the inlet 20 as the connector 20 and the wiring member 50. FIG. FIG. 6 is a front view showing the inlet 20 as the connector 20. FIG. 5 is a view from the inside of the vehicle, and FIG. 6 is a view from the outside of the vehicle. In FIG. 5, the grommet 60 indicated by the phantom line is located at the attachment position to the inlet 20 when viewed from the X direction.

A housing 21 in the inlet 20 has a body portion 22 and a retainer 32 . The body portion 22 and retainer 32 are connected in the X direction to form one housing 21 .

The body portion 22 has a first housing portion 23 . The first housing part 23 extends through the through hole 84 . The outer shape of the first housing portion 23 is preferably shaped according to the shape of the through hole 84 . Here, the outer shape of the first housing portion 23 and the shape of the through hole 84 are circular. The first housing portion 23 is formed with a first cavity 25 and a first drain hole 26 penetrating through the first housing portion 23 in the X direction.

The retainer 32 has a second housing portion 33 . The second housing portion 33 is formed with a second cavity 35 and a second drain hole 36 that pass through the second housing portion 33 in the X direction.

The first housing portion 23 and the second housing portion 33 are arranged in the X direction. The second housing portion 33 is located on the rear side (inner side of the vehicle along the X direction) than the first housing portion 23 . A rear surface 34 of the housing 21 is provided in the second housing part 33 . Here, the length dimension of the second housing part 33 along the X direction is smaller than the length dimension of the first housing part 23 along the X direction. The length dimension of the second housing portion 33 along the X direction may be equal to or greater than the length dimension of the first housing portion 23 along the X direction.

The first cavity 25 and the second cavity 35 communicate in the X direction to form one cavity. The cavity opens into the rear surface 34 of housing 21 . A terminal 40 is accommodated in the cavity to form a connecting portion. One end of terminal 40 is electrically connected to a terminal of the external charging connector when the external charging connector is inserted into inlet 20 . The other end of terminal 40 is electrically connected to wiring member 50 . In the inlet 20, the terminal 40 and the wiring member 50 are maintained in a connected state. The mode of connection between the terminal 40 and the wiring member 50 is not particularly limited, and may be crimping, welding, or the like.

Here, the terminals 40 include a plurality of (two in the example shown in FIG. 5) first terminals 40A for power supply lines and a plurality (two in the example shown in FIG. 5) second terminals 40B for signal lines. is provided. As the wiring members 50, a plurality of (two in the example shown in FIG. 5) wiring members 50A used as power lines and a plurality of (two in the example shown in FIG. 5) wiring members 50B used as signal lines. is provided. Each of the four wiring members 50 is a single covered electric wire having a conductor and a covering layer. One end of the wiring member 50A is connected to the first terminal 40A, and one end of the wiring member 50B is connected to the second terminal 40B. The four wiring members 50 extend out of the grommet 60 at intermediate portions on the way from one end to the other end. In this example, four wiring members 50 extend from the grommet 60 along the Y direction. The other ends of the four wiring members 50 are connected to respective connection partners. The connection partner is set according to the specifications of the wiring system of the vehicle. For example, when the connector 20 is the inlet 20, the connection partner may be a power storage device, an AC-DC converter, a DC-DC converter, an electronic control unit (ECU), or the like.

The first terminal 40A for the power line includes a connector terminal 41 and a relay terminal 42. The connector terminals 41 are connected to terminals of the mating connector. Connector terminals 41 fit within cavities of housing 21 . The relay terminal 42 is connected to the connector terminal 41 and the wiring member 50A. One end of relay terminal 42 is connected to connector terminal 41 . The other end of the relay terminal 42 is connected to the wiring member 50A. The manner of connection between the relay terminal 42 and the connector terminal 41 is not particularly limited, and can be set as appropriate. For example, the connection mode between the relay terminal 42 and the connector terminal 41 may be a connection mode in which the relay terminal 42 and the connector terminal 41 can be connected after the connector terminal 41 is housed in the cavity. Such a connection mode may be, for example, screwing or tab fitting. The connection mode between the relay terminal 42 and the connector terminal 41 may be easier to attach and detach (disconnect and reconnect) after connection than the connection mode between the relay terminal 42 and the wiring member 50A. As a combination of such connection modes, the connection mode between the relay terminal 42 and the connector terminal 41 is fitting by screws or tabs, and the connection mode between the relay terminal 42 and the wiring member 50A is crimping, welding, or the like. Combinations are envisioned.

One end of the relay terminal 42 is located at a position overlapping the connector terminal 41 when viewed from the X direction. The connecting portion between the relay terminal 42 and the connector terminal 41 may be housed in the cavity, or may be arranged outside the cavity. is.

The other end of the relay terminal 42 is arranged outside the cavity. The other end of the relay terminal 42 is arranged on the rear surface 34 . A portion of the relay terminal 42 that is connected to the wiring member 50A (the other end of the relay terminal 42) extends in the direction in which the wiring member 50A extends from the grommet 60 (here, the Y direction). The relay terminal 42 extends along the rear surface 34 from the other end toward the one end. At this time, one relay terminal 42 of the two first terminals 40A extends in the Y direction from the other end toward the one end, then bends in the middle, and extends in a direction crossing the Y direction on the rear surface 34. (here, in the Z direction). The other relay terminal 42 of the two first terminals 40A extends in the Y direction from the other end toward the one end and reaches the one end as it is.

The second terminal 40B for the signal line has both a portion connected to the terminal of the mating connector and a portion connected to the wiring member 50B in one terminal. A portion of the second terminal 40B that is connected to the terminal of the mating connector is accommodated in the cavity. A portion of the second terminal 40B that is connected to the wiring member 50B is also housed in the cavity. Therefore, the tip of the wiring member 50B connected to the second terminal 40B is also accommodated in the cavity. A covered portion of the wiring member 50</b>B is arranged on the rear surface 34 . Therefore, the wiring member 50B and the relay terminal 42 of the first terminal 40A are unlikely to be short-circuited. A portion of the second terminal 40B that is connected to the wiring member 50B may be arranged outside the cavity.

As shown in FIG. 6, two cavities for the first terminals 40A are provided apart in the Y direction. A cavity for the second terminal 40B is provided along the Y direction between two cavities for the first terminal 40A. The two cavities for the second terminals 40B are spaced apart along the Z direction. A cavity for the first terminal 40A is provided along the Z direction between two cavities for the second terminal 40B.

The wiring member 50A is thicker than the wiring member 50B. Therefore, the wiring member 50A is less likely to bend than the wiring member 50B. Conversely, the wiring member 50B bends more easily than the wiring member 50A. This is due to the difference in magnitude of current flowing through the wiring member 50A and the wiring member 50B. That is, a relatively large charging current flows through the wiring member 50A serving as the power supply line. Therefore, the wiring member 50A requires a relatively large conductor cross-sectional area. The signal current flowing through the wiring member 50B serving as the signal line is relatively small. Therefore, the wiring member 50B needs only a relatively small conductor cross-sectional area. Therefore, the wiring member 50A is thicker than the wiring member 50B.

Of course, the number and uses of the terminals 40 are not limited to this. The number and use of the terminals 40 can be appropriately set according to the number and use of the terminals of the external charging connector. For example, as terminals, the first terminal 40A having the connector terminal 41 and the relay terminal 42 may not be provided. Similarly, the number and use of the wiring members 50 are not limited to this, and can be appropriately set according to the specifications of the charging system of the vehicle, the use of the wire harness 10, and the like. For example, a composite cable in which a plurality of single wires are covered with one sheath may be used as the wiring member 50, and the composite cable may extend from the outside of the grommet 60 to the inside. Further, for example, wiring members in the wire harness 10 may not be connected to the external charging connector. As such a wiring member, for example, there may be one that is connected to an electric component such as a sensor incorporated in the inlet 20 .

The first drain hole 26 and the second drain hole 36 communicate in the X direction to form one drain hole. The drain hole prevents water from accumulating in the space outside the panel 82 of the inlet mounting portion 80 . Water accumulated in the space outside the panel 82 of the inlet mounting portion 80 is guided to the space inside the panel 82 through the drain hole. Here, water is guided inside the grommet 60 through the drainage holes. This water is discharged out of the grommet 60 through the drain port 73 in the grommet 60 .

A fixed portion 28 is provided on the housing 21 . The fixing portion 28 is a portion used for fixing to the vehicle. Here, the fixing portion 28 is provided on the body portion 22 . The fixing portion 28 protrudes like a flange from the outer surface of the first housing portion 23 (here, the outer surface of the portion located on the inner side of the vehicle relative to the panel 82). The fixing portion 28 is formed larger than the through hole 84 of the panel 82 . The manner in which the fixing portion 28 and the panel 82 are fixed is not particularly limited, but they may be fixed as follows, for example. That is, a fixing hole is formed in the fixing portion 28 . A stud bolt is provided on the inner surface of the peripheral portion of the through hole 84 in the panel 82 . A stud bolt is fastened to the fixing hole to fix the fixing portion 28 and the panel 82 . The inlet 20 (wire harness 10 ) is thereby attached to the inlet attachment portion 80 .

A housing-side partition 37 is provided on the housing 21 . A housing-side partition 37 is provided on the rear surface 34 of the housing 21 . Here, since the rear surface 34 of the housing 21 is provided on the retainer 32 , the housing-side partition 37 is provided on the retainer 32 . The housing side partition 37 is formed in a plate shape and protrudes in the X direction from the rear surface 34 of the second housing portion 33 . The end of the housing-side partition 37 along the X direction is open. The housing-side partition 37 has a first partition 38 . Furthermore, the housing-side partition 37 has a second partition 39 .

The first partition 38 divides the rear surface 34 into a first area where the opening of the cavity exists and a second area located closer to the drain port 73 than the first area. On the rear surface 34, the drain hole openings are provided in the second region. Therefore, the first partition 38 separates the opening of the drain hole and the opening of the cavity. At least a portion of the first partition 38 between the one side and the other side is arranged so that the one side of the first partition 38 is closer to the drain port 73 along the Z direction than the other side of the first partition 38 is. sloping at the bottom. In the first partition 38, this slanted portion is the slanted portion. The first partition 38 may be configured with only an inclined portion between the one side portion and the other side portion. Here, the first partition 38 includes a horizontal portion in addition to the inclined portion between one side and the other side. A horizontal portion is a portion that extends along a plane perpendicular to the Z direction. Here, a horizontal portion is provided between two inclined portions. The portion including the one side portion and the portion including the other side portion are each an inclined portion. The horizontal portion is provided next to (downward along the Z direction) the cavity in which the second terminal 40B is accommodated.

One side of the first partition 38 is located on one side of the drain port 73 along the Y direction, and the other side of the first partition 38 is located on the other side of the drain port 73 along the Y direction. do. One side of the first partition 38 does not reach the peripheral edge of the rear surface 34 . One side of the first partition 38 may reach the periphery of the rear surface 34 . Similarly, the other side of first partition 38 does not reach the peripheral edge of back surface 34 . The other side of the first partition 38 may reach the periphery of the rear surface 34 .

The second partition 39 protrudes in the X direction from a position on the rear surface 34 of the housing 21 different from the position of the first partition 38 . The second partition 39 surrounds the portion of the terminal 40 that is arranged on the rear surface 34 . Here, the second partition 39 partitions the relay terminals 42 of the first terminal 40A. Here, two second partitions 39 are provided so as to surround each relay terminal 42 . Each second partition 39 surrounds the opening of the cavity on three sides. Thereby, the posture (orientation) of each relay terminal 42 is regulated by the second partition 39 .

Each second partition 39 is partially open in the YZ plane. A portion of the relay terminal 42 on the other end side protrudes outward from the second partition 39 through the opening. Here, the two second partitions 39 are open in different directions. The opening of one of the two second partitions 39 opens upward along the Z direction. The opening of the other second partition 39 of the two second partitions 39 opens along the Y direction. However, the openings of the two second partitions 39 may open in the same direction.

The two second partitions 39 are spaced apart in the Y direction. For this reason, two walls, one wall of the second partition 39 and the other wall of the second partition 39 , are provided between the relay terminals 42 . One wiring member 50B of the two wiring members 50B passes between the two walls and merges with the other wiring member 50B. One wiring member 50B is a wiring member 50B housed in a cavity far from the drain port 73 along the Z direction. The other wiring member 50B is the wiring member 50B housed in a cavity near the drain port 73 along the Z direction. The two wiring members 50B extend in the Y direction after joining. The two second partitions 39 may be in contact with each other in the Y direction. In this case, it can be considered that there is one wall separating the relay terminals 42 . In this case, one wiring member 50B may pass over the wall and merge with the other wiring member 50B.

One of the two second partitions 39 partly overlaps with part of the first partition 38 . Here, the sloped portion of the first partition 38 on the other side overlaps with the lower portion of one second partition 39 along the Z direction. The other of the two second partitions 39 is not connected to the first partition 38 . The two wiring members 50B extend in the Y direction between the other second partition 39 and the first partition 38 .

The projection dimension of the first partition 38 along the X direction from the back surface 34 may be a dimension that allows contact with the inner surface of the grommet 60 . The projection dimension of the first partition 38 along the X direction from the rear surface 34 may be equal to or larger than the distance between the rear surface 34 and the inner surface of the grommet 60 . The projection dimension of the second partition 39 along the X direction from the back surface 34 may be a dimension such that the relay terminal 42 is not exposed on the tip side of the second partition 39 . The projection dimension of the second partition 39 along the X direction from the rear surface 34 may be the same as or larger than the projection dimension of the relay terminal 42 along the X direction from the rear surface 34 .

The second partition 39 has a portion whose projection dimension along the X direction from the back surface 34 is smaller than the projection dimension of the first partition 38 along the X direction from the back surface 34 . Here, in all the walls of the second partition 39 except for the wall common to the first partition 38, the projection dimension along the X direction from the back surface 34 is the first partition 38 along the X direction from the back surface 34 smaller than the projecting dimension of However, the portion of the second partition 39 where the projection dimension along the X direction from the back surface 34 is smaller than the projection dimension of the first partition 38 along the X direction from the back surface 34 is not limited to this. For example, when two second partitions 39 are in contact with each other in the Y direction and there is one wall partitioning between the relay terminals 42, the projection dimension of the wall along the X direction from the back surface 34 is may be smaller than the projecting dimension of the first partition 38 along the X direction. Further, for example, in the portion of one of the second partitions 39 that is connected to the first partition 38 on the lower side of the inclined portion, the projection dimension along the X direction from the back surface 34 is It may be smaller than the projecting dimension of one partition 38 .

The body portion 22 is an integrally molded product in which the first housing portion 23 and the fixing portion 28 are integrally formed. The retainer 32 is an integrally molded product in which the second housing portion 33 and the housing-side partition 37 are integrally formed. The main body portion 22 and the retainer 32 are each made of a material such as a resin having insulating properties. The main body portion 22 and the retainer 32 may be integrally molded with a material such as resin.

<Grommet>
Grommet 60 will now be described with reference to FIGS. 1-6 as well as FIGS. 7 and 8 are perspective views showing the grommet 60. FIG. 7 and 8 are perspective views seen from different directions.

The grommet 60 includes a grommet body portion 62 and a flange portion 76. The grommet 60 is an integrally molded product in which a grommet body portion 62 and a flange portion 76 are integrally formed. The grommet 60 is made of an elastic material. As a material of the grommet 60, for example, an elastomer such as EPDM (ethylene propylene diene rubber) having high elasticity can be used. The grommet 60 may be formed integrally with a mold from a material having elasticity as described above. The resin, which is the material of the body portion 22 of the inlet 20 and the retainer 32, is preferably a material harder than the elastomer.

The grommet main body 62 covers the inlet 20 and the wiring member 50 . A connection port 67 , a lead-out port 70 and a drain port 73 are formed in the grommet body portion 62 . A portion of the inlet 20 that is connected to the external charging connector is inserted through the connection port 67 . The wiring member 50 is inserted through the outlet 70 . Water in the grommet main body 62 is discharged from the drain port 73 . The connection port 67 is larger than the outlet port 70 and the drain port 73 .

In the present disclosure, the direction in which the cavity penetrates the housing 21 is defined as the first direction. The first direction is parallel to the X direction. The first direction is also the direction in which the connection port 67 opens. The direction in which the outlet 70 opens is defined as the second direction, and the direction in which the drain port 73 opens is defined as the third direction. As described above, the outlet port 70 opens in the Y direction and the drain port 73 opens in the Z direction. Therefore, here, the first direction, the second direction and the third direction are orthogonal to each other. However, the first direction, the second direction and the third direction do not have to be orthogonal to each other. For example, the second direction may be a direction crossing the X, Y and Z directions.

In this example, the connecting port 67 is provided with a cylindrical connecting tube portion 68 . The drawer port 70 is provided with a drawer tubular portion 71 formed in a tubular shape. The drainage port 73 is provided with a tubular drainage tube portion 74 .

The connecting tubular portion 68 is formed in a tubular shape with a similar cross-sectional shape continuing in the X direction. The connection tube portion 68 extends the connection port 67 in the X direction. A lip portion 69 is provided on the inner surface of the connecting tube portion 68 . The lip portion 69 is annularly formed so as to be able to come into contact with the outer surface of the connecting portion (here, the outer surface of the first housing portion 23). By pressing the lip portion 69 against the outer surface of the connection portion, water is stopped between the inlet 20 and the grommet 60 at the connection port 67 .

The pull-out tubular portion 71 is formed in a tubular shape with a similar cross-sectional shape continuing in the Y direction. The drawer tube portion 71 extends the drawer port 70 in the Y direction. A lip portion 72 is provided on the inner surface of the drawer cylinder portion 71 . The lip portion 72 is formed in an annular shape so as to be able to contact the wiring member 50 . By pressing the lip portion 69 against the outer surface of the wiring member 50 , water is stopped between the wiring member 50 and the grommet 60 at the outlet 70 .

In this example, a plurality of (three in the example shown in FIG. 1) drawer cylinder portions 71 (drawer openings 70) are formed. Of the three pull-out tubular portions 71, two pull-out tubular portions 71A are formed with lip portions 72, and the remaining one pull-out tubular portion 71B is not formed with a lip portion 72. As shown in FIG. Two wiring members 50A are separately inserted into the two drawer tube portions 71A. Two wiring members 50B are collectively inserted into one drawer tube portion 71B.

The pull-out tubular portion 71A is preferably provided at the same position as the connecting portion between the relay terminal 42 and the wiring member 50A in the X direction and the Z direction. It is preferable that the lead-out tubular portion 71A is located at a point moved in the Y direction from the connecting portion between the relay terminal 42 and the wiring member 50A. This allows the wiring member 50A to extend in the Y direction inside the grommet 60 without bending as much as possible. The drawer cylinder part 71B is provided below the two drawer cylinder parts 71A along the Z direction.

The drainage tube part 74 is formed in a tubular shape with a similar cross-sectional shape continuing in the Z direction. The drain tube portion 74 extends the drain port 73 in the Z direction. Here, the drain port 73 and the drain tube portion 74 are rectangular. The drain port 73 and the drain tube portion 74 may be circular or the like.

In this example, the grommet body portion 62 has a first body portion 63 and a second body portion 66 . The first body portion 63 is a portion that mainly covers the connecting portion of the inlet 20 . The second body portion 66 is a portion that mainly covers a portion of the wiring member 50 that is on the other end side of the portion that is connected to the terminal 40 and that extends in the Y direction. The first body portion 63 and the second body portion 66 are each hollow, and the internal space of the first body portion 63 and the internal space of the second body portion 66 are connected. The first body portion 63 may have any shape as long as it can cover the connecting portion of the inlet 20 , and it is preferable that the shape corresponds to the connecting portion of the inlet 20 . The second body portion 66 may have any shape as long as it can cover the portion of the wiring member 50 extending in the Y direction. The internal space of the second body portion 66 is larger than the total outer shape of the plurality of wiring members 50 . The second body portion 66 can accommodate the plurality of wiring members 50 without sticking to each other. Here, the first main body portion 63 has a circular cross section that continues in the X direction, and the second main body portion 66 has a rectangular cross section (here, a rectangular cross section) that continues in the Y direction.

The first body portion 63 has a first cover portion 64 and a second cover portion 65 . A connection port 67 is provided at one end of the first body portion 63 along the X direction. No opening is formed at the other end of the first body portion 63 along the X direction (the end opposite to the end where the connection port 67 is provided). The first cover portion 64 and the second cover portion 65 are provided at the other end of the first body portion 63 along the X direction. The first cover portion 64 faces the rear surface 34 of the inlet 20 . The first cover portion 64 covers the rear surface 34 of the inlet 20 . The second cover portion 65 covers the periphery of the back surface 34 of the inlet 20 . The second cover portion 65 is cylindrical, and the first cover portion 64 covers the second cover portion 65 from the side opposite to the connection port 67 . A drain port 73 is provided in the second cover portion 65 . The drain port 73 is provided at the lowest portion of the second cover portion 65 along the Z direction. A drawer port 70 is provided in a portion of the second cover portion 65 that is different from the portion in which the drain port 73 is formed. In this example, the outlet 70 is provided at the tip of the second body portion 66 along the Y direction. The outlet 70 continues to the second cover portion 65 via the second body portion 66 . The second main body portion 66 and the lead-out port 70 are large lead-out ports in which the second main body portion 66 collectively accommodates the plurality of wiring members 50, and the lead-out port 70 accommodates the plurality of wiring members 50 separately. It can also be regarded as a small outlet.

The tip of the first partition 38 is in contact with the inner surface of the first cover portion 64. The first partition 38 is preferably in contact with the inner surface of the first cover portion 64 from one side to at least a portion located above the drain port 73 . The first partition 38 may be in contact with the inner surface of the first cover portion 64 over the entire length from one side to the other side.

The first cover portion 64 is provided with a thick portion 64a that is partially thick. The inner surface of the thick portion 64 a is in contact with the first partition 38 . The thick portion 64a is provided in a portion corresponding to the entirety of the first partition 38 from one side to the other side. An upper edge portion of the thick portion 64 a along the Z direction is inclined according to the inclined portion of the first partition 38 . The thick portion 64a is connected to the second cover portion 65 on the lower side along the Z direction. The second cover portion 65 is recessed toward the center of the circle below the thick portion 64a along the Z direction. A connecting portion between the thick portion 64 a and the second cover portion 65 is inclined according to the inclined portion of the first partition 38 . As a result, the thick portion 64a is connected to the second cover portion 65 on the lower side in the Z direction, and an increase in the area where the thick portion 64a is provided can be suppressed.

The tip surface of the tip portion of the first partition 38 is in surface contact with the inner surface of the first cover portion 64 (here, the inner surface of the thick portion 64a). A portion of the inner surface of the first cover portion 64 (in this case, the inner surface of the thick portion 64a) that contacts the tip surface of the tip portion of the first partition 38 is a flat surface parallel to the YZ plane. The dimension along the Z direction of the flat surface is larger than the dimension along the Z direction of the front end surface of the front end portion of the first partition 38 . As a result, the tip surface of the tip portion of the first partition 38 is likely to be in surface contact with the flat surface. Here, the inner surface of the thick portion 64a is a flat surface as a whole. The dimension along the Z direction of the thick portion 64a is larger than the dimension along the Z direction of the tip surface of the tip portion of the first partition 38 .

The space containing the first area and the space containing the second area are not completely separated by the grommet 60 and the first partition 38. Inside the grommet 60 , the space containing the first region and the space containing the second region are not separate spaces, but communicate with each other through a communicating portion such as a gap between the first partition 38 and the inner surface of the grommet 60 . .

Here, on one side of the first partition 38, the space including the first area and the space including the second area are in communication. Here, there is a gap between the grommet 60 and the first partition 38 on one side of the first partition 38 . One side portion of the first partition 38 is not in contact with the inner peripheral surface of the second cover portion 65 of the grommet 60 . Here, since the second body portion 66 is provided on the second cover portion 65 , the second cover portion 65 does not have a portion facing the end surface of the one side portion of the first partition 38 . Accordingly, one side portion of the first partition 38 is not in contact with the inner peripheral surface of the second cover portion 65 of the grommet 60 . If the second cover portion 65 has a portion facing the one side end surface of the first partition 38, the inner peripheral surface of the second cover portion 65 and the one side end surface of the first partition 38 are , may be spaced apart.

The inner peripheral surface of the second cover portion 65 and the end surface of the other side portion of the first partition 38 face each other with a gap therebetween. However, the inner peripheral surface of the second cover portion 65 and the end surface of the other side portion of the first partition 38 may be in contact with each other. A portion of the inner peripheral surface of the second cover portion 65 that is in contact with the end surface of the other side portion of the first partition 38 may be partially formed thick.

A grommet-side partition 75 is provided on the grommet body portion 62 . The grommet-side partition 75 overlaps the drain port 73 when viewed from the Z direction. The grommet-side partition 75 is arranged between the first partition 38 and the drain port 73 along the Z direction. The grommet-side partition 75 protrudes from the inner surface of the first cover portion 64 along the X direction. The grommet-side partition 75 has a partition body 75a and a pair of legs 75b. The partition main body 75a is a portion that overlaps with the drain port 73 when viewed from the Z direction. The partition main body 75a is provided spaced apart from the drain port 73 along the Z direction. The pair of leg portions 75b are portions that connect the partition main body 75a and the second cover portion 65 . The pair of leg portions 75b are provided apart from each other along the Y direction. A drain port 73 is provided between a pair of leg portions 75b along the Y direction. When viewed from the Z direction, the partition body 75a does not overlap the drain port 73 on the connection portion side along the X direction. As a result, water can easily reach the drain port 73 from the opening of the drain hole in the inlet 20 . However, the partition body 75a may overlap the entire drain port 73 when viewed from the Z direction.

The first partition 38 extends from the rear surface 34 to the inner surface of the first cover portion 64 above the partition main body 75a in the Z direction. The first partition 38 is also provided in a portion where the grommet side partition 75 is absent when viewed from the Z direction. As a result, the first partition 38 can prevent dust and the like from entering the space including the first region from a portion without the grommet side partition 75 .

The flange portion 76 is provided around the tip portion of the connection tube portion 68 along the X direction. The collar portion 76 is formed in an annular shape on the side surface of the connecting tube portion 68 along the entire circumference. Of course, the collar portion 76 does not have to be ring-shaped around the entire circumference of the side surface of the connection tube portion 68 , and may be partially formed on the side surface of the connection tube portion 68 . For example, an operator can grip the collar portion 76 when performing the task of attaching the grommet 60 to the inlet 20 , particularly when performing the task of shifting the connection port 67 in the X direction with respect to the inlet 20 . As a result, the workability of attaching the grommet 60 to the inlet 20 can be improved.

<Effects, etc.>
According to the wire harness 10 configured as described above, since the tip of the first partition 38 in the X direction is in contact with the inner surface of the grommet 60, even if dust or the like enters the grommet 60 from the drain port 73, , the dust or the like is less likely to reach the space including the first region where the opening of the cavity is located. Accordingly, even when the drain port 73 of the grommet 60 is short, adhesion of dust or the like to the terminal 40 can be suppressed.

In addition, the inner surface of the thick portion 64a is in contact with the first partition 38. As a result, the thick portion 64a of the grommet 60 can easily receive the force from the first partition 38, and the grommet 60 and the first partition 38 can be easily kept in contact with each other. For example, even if the portion of the grommet 60 that is in contact with the first partition 38 receives force from the first partition 38 , deformation that creates a gap between the grommet 60 and the first partition 38 is less likely to occur.

In addition, the tip surface of the tip portion of the first partition 38 is in surface contact with the inner surface of the first cover portion 64 . This facilitates keeping the grommet 60 and the first partition 38 in proper contact with each other. For example, if the side surface, corner, etc. of the tip of the first partition 38 are in contact with the inner surface of the first cover portion 64, the reaction force from the grommet 60 crosses the first partition 38 in the X direction. direction and may act as a bending moment. On the other hand, if the tip surface of the tip portion of the first partition 38 is in surface contact with the inner surface of the first cover portion 64, the reaction force from the grommet 60 is applied to the first partition 38 in the X direction. Therefore, it is difficult to act as a bending moment.

In addition, on the back surface 34, the opening of the drain hole is located in the second region where the drain port 73 is located. As a result, water entering the grommet 60 through the drain hole can easily reach the drain port 73 .

In addition, the first partition 38 is inclined at least partially between the one side and the other side so that the one side of the first partition 38 is closer to the drain port 73 than the other side of the first partition 38. The space containing the first area and the space containing the second area communicate with each other on one side of the first partition 38 . As a result, when the wire harness 10 is arranged so that the drain port 73 faces the vertical direction, water that has entered the space including the first region from the cavity flows along the first partition 38 and enters the space including the second region. can reach.

Also, the side portion of the first partition 38 is not in contact with the inner peripheral surface of the second cover portion 65 of the grommet 60 . As a result, the gap between the grommet 60 and the first partition 38 can be used to allow water in the space containing the first area to escape to the space containing the second area.

In addition, the retainer 32 is provided with a rear surface 34 and a first partition 38 . As a result, even if the first partition 38 is changed according to the extending direction of the wiring member 50 or the like, it can be dealt with by changing the retainer 32 . In this case, the body portion 22 can be used as a common component.

Also, the wiring member 50 extends from the grommet 60 in the Y direction intersecting the X direction, and the wiring member Fifty outlets 70 are formed. As a result, compared to the case where the wiring member 50 extends from the grommet 60 in the X direction, even if the load of the wiring member 50 is applied to the grommet 60, the load separates the contacting portions of the first partition 38 and the grommet 60 from each other. It becomes difficult to act in the direction, and the inner surface of the grommet 60 and the first partition 38 are easily kept in contact with each other. Also, the height of the portion of the wire harness 10 where the grommet 60 is attached to the inlet 20 can be reduced in the X direction. In other words, the parts constituting the wire harness 10 are not positioned behind the first cover portion 64 of the grommet 60 in the X direction. As a result, the peripheral parts of the vehicle can be arranged behind the first cover portion 64 of the grommet 60 in the X direction.

Also, the portion of the relay terminal 42 that is connected to the wiring member 50A extends in the direction in which the wiring member 50A extends from the grommet 60 . Accordingly, even when the wiring member 50A extends from the grommet 60 in the direction crossing the X direction, the wiring member 50A can extend from the grommet 60 without bending inside the grommet 60 as much as possible.

In addition, the wiring member 50 has a wiring member 50B serving as a signal line, and the terminal 40 has a second terminal 40B connected to the wiring member 50B. The opening of the cavity that accommodates the second terminal 40B is also located in the first region. As a result, adhesion of dust or the like to the second terminal 40B for the signal line can also be suppressed.

In addition, the second partition 39 has a portion whose projection dimension along the X direction from the back surface 34 is smaller than the projection dimension of the first partition 38 along the X direction from the back surface 34 . This makes it difficult for the second partition 39 to come into contact with the grommet 60 , thereby making it easier to keep the first partition 38 and the grommet 60 in contact with each other.

[Note]
FIG. 9 is a rear view showing a first modified example of the grommet 60. FIG.

Although it has been described so far that all of the plurality of outlets 70 are provided on the same surface of the second body portion 66, this is not an essential configuration. Like the grommet 160 shown in FIG. 9 , in the second main body portion 66 , the surface on which some of the outlets 70 are provided may be different from the surface on which the other part of the outlets 70 are provided. In the grommet 160 shown in FIG. 9 , the surface on which some of the outlets 70 are provided is farther in the Y direction from the center of the first body portion 63 than the surface on which some of the other outlets 70 are provided. In the grommet 160 shown in FIG. 9, the lead-out port 70A through which the wiring member 50A used as the power line is inserted is located at the center of the first main body portion 63 rather than the lead-out port 70B through which the wiring member 50B used as the signal line is inserted. away from in the Y direction. Even if the outlet 70B through which the wiring member 50B used as the signal line is inserted is farther in the Y direction from the center of the first main body 63 than the outlet 70A through which the wiring member 50A used as the power supply line is inserted. good.

FIG. 10 is a perspective view showing a second modified example of the grommet 60. FIG.

Although the grommet body portion 62 has been described as having the second body portion 66 so far, this is not an essential configuration. Like the grommet 260 shown in FIG. 10 , the grommet body portion 62 does not have to have the second body portion 66 . The outlet 70 may be provided directly in the second cover portion 65 .

Also, although it has been described that a plurality of outlets 70 are provided, this is not an essential configuration. Only one outlet 70 may be provided like the grommet 260 shown in FIG. In this case, there may be a plurality of wiring members 50 extending from the grommet 260 , and the plurality of wiring members 50 may be collectively inserted into one outlet 70 . Also, only one wiring member 50 may extend from the grommet 260 .

Also, the example in which the outlet 70 is open on the positive side in the Y direction has been described so far, but this is not an essential configuration. Like the grommet 260 shown in FIG. 10, the extraction port 70 may be open on the negative side in the Y direction.

In addition, the inner surface of the thick portion 64a has been described so far as being in contact with the tip of the first partition 38, but this is not an essential configuration. The portion of the first cover portion 64 that contacts the tip portion of the first partition 38 does not have to be the thick portion 64a.

Further, the description has been made so far that the tip surface of the tip portion of the first partition 38 is in surface contact with the inner surface of the first cover portion 64, but this is not an essential configuration. A side surface, a corner portion, or the like of the tip portion of the first partition 38 may be in contact with the inner surface of the first cover portion 64 .

Also, heretofore, the first partition 38 was at least partly between one side and the other side so that one side of the first partition 38 was closer to the drain port 73 than the other side of the first partition 38 was. , and the space containing the first region and the space containing the second region communicate with each other on one side of the first partition 38, but this is an essential configuration. is not. For example, the first partition 38 may extend parallel to the Y direction.

Also, it has been described so far that one side portion of the first partition 38 is not in contact with the inner peripheral surface of the second cover portion 65 of the grommet 60, but this is not an essential configuration. One side portion of the first partition 38 may be in contact with the inner peripheral surface of the second cover portion 65 of the grommet 60 . Also in this case, it is preferable that the space including the first area and the space including the second area communicate with each other on one side of the first partition 38 .

Also, the housing 21 has been described so far as having the body portion 22 and the retainer 32 that are adjacent to each other along the X direction, but this is not an essential configuration. For example, the housing 21 may be formed integrally with a mold so as to have the body portion 22 and the retainer 32 .

In addition, the wiring member 50 has been extended from the grommet 60 in the direction crossing the X direction, and the wiring member 50 has been connected to a portion of the second cover portion 65 of the grommet 60 other than the portion where the drain port 73 is formed. Although described as having an outlet 70 for member 50, this is not essential. For example, the outlet 70 may open in the X direction. That is, in the body portion 22, the connection port 67 and the outlet 70 may be formed on opposite sides along the first direction.

Also, the connection portion of the relay terminal 42 with the wiring member 50A has been described so far as extending in the Y direction in which the wiring member 50A extends from the grommet 60, but this is not an essential configuration. For example, the connection portion of the relay terminal 42 with the wiring member 50A may extend in a direction different from the Y direction, such as the Z direction. 50 A of wiring members may be bent inside the grommet 60, and may be arrange|positioned.

Also, the wiring member 50 has been described as having the wiring member 50B serving as the signal line, and the terminal 40 has the second terminal 40B connected to the wiring member 50B, but this is an essential configuration. is not. The wiring member 50 may not include the wiring member 50B serving as the signal line. The wiring member 50 may be composed only of the wiring member 50A serving as the power supply line.

Further, heretofore, on the back surface 34 of the housing 21, a second partition 39 is provided that protrudes in the X direction from a position different from the first partition 38 and surrounds the portion of the terminal 40 that is arranged on the back surface 34. Although the partition 39 has been described as having a portion that projects from the rear surface 34 along the X direction less than the projection dimension of the first partition 38 from the rear surface 34 along the X direction, this is essential. is not the composition of For example, the second partition 39 may not be provided on the rear surface 34 of the housing 21 . Further, for example, at any part of the second partition 39, the projection dimension along the X direction from the back surface 34 is the same as or larger than the projection dimension of the first partition 38 along the X direction from the back surface 34. may

In addition, although it has been described that the opening of the drain hole is located in the second region on the back surface 34, this is not an essential configuration. In the back surface 34, the opening of the drainage holes may be located in the first region.

Also, drain holes may be omitted. In this case, the wire harness of the present disclosure includes a connector having a terminal and a housing holding the terminal, a wiring member connected to the terminal and extending from the connector, and a grommet covering the connector and the wiring member.
