Embodiments for Carrying Out the Invention

[0010] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The wiring member of the present disclosure is as follows.

[0012] (1) A wiring member connected to a movable part in a movable device provided in a vehicle, the wiring member including: a connector connected to the movable part and moving along with the movement of the movable part; an electric wire extending from a rear end portion of the connector; a protection member covering the electric wire at a position away from the connector along the extending direction of the electric wire; and a connector cover covering the rear end portion of the connector, an end portion of the protection member, and a portion of the electric wire between the connector and the protection member. The connector cover moves integrally with the connector and is relatively movable with respect to the protection member, and an overlapping dimension between the connector cover and the protection member in the extending direction of the electric wire is equal to or greater than the amount of movement in the movable part. Since the overlapping dimension between the connector cover and the protection member in the extending direction of the electric wire is equal to or greater than the amount of movement in the movable part, even if the connector and the connector cover move along with the movement of the movable part, the protection member is prevented from falling off from the connector cover.

[0013] (2) In the wiring member of (1), a fixed-position fixing portion that is fixed to a fixed position with respect to the vehicle regardless of the presence or absence of movement of the movable part may be provided at an intermediate portion along the extending direction of the wiring member. Thereby, even if a portion on the connector side relative to the fixed-position fixing portion moves, the protection member is prevented from falling off from the connector cover.

[0014] (3) In the wiring member of (2), the fixed-position fixing portion may be provided at a portion of the protection member that extends outside the connector cover. Thereby, the portion of the protection member that extends outside the connector cover is fixed to a fixed position with respect to the vehicle regardless of the presence or absence of movement of the movable part.

[0015] (4) In any one of the wiring members (1) to (3), the movable device includes a wear member that wears out as the vehicle is used. As the wear member wears out, the amount of movement of the movable part increases, and the overlapping dimension between the connector cover and the protection member in the extending direction of the electric wire may be equal to or greater than the amount of movement of the movable part when the wear member reaches the wear limit. Thereby, even when the connector and the connector cover move as the movable part moves when the wear member reaches the wear limit, the protection member is suppressed from falling off the connector cover.

[0016] (5) In any one of the wiring members (1) to (4), the protection member has an outer surface with a shape that is uniform in the axial direction and continuous. The connector cover has a connector cover body and a protrusion that protrudes from the connector cover body toward the outer surface of the protection member. The protrusion may be in contact with the outer surface of the protection member and at least one of the protection member and the protrusion may be elastically deformed. Thereby, it becomes difficult for the protection member to fall off the connector cover.

[0017] (6) In the wiring member of (5), a hole is formed around the connecting portion between the connector cover body and the protrusion, and the protrusion may be elastically deformable in the inner and outer directions of the connector cover via the connecting portion. Thereby, when the protection member inserted into the connector cover comes into contact with the protrusion, the protrusion can be elastically deformed, making it easier for the protection member to be inserted into the connector cover.

[0018] (7) In any one of the wiring members (1) to (6), a drain hole may be formed in the connector cover. Thereby, it is suppressed that water accumulates inside the connector cover.

[0019] (8) In any one of the wiring members (1) to (7), the overlapping dimension between the connector cover and the protection member in the extending direction of the electric wire may be equal to or greater than the fitting dimension between the connector and the mating connector in the movable part. Thereby, even when the connector and the connector cover move when the connector is connected to the mating connector, the protection member is suppressed from falling off the connector cover.

[0020] [Details of Embodiments of the Present Disclosure] Specific examples of the wiring member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, and is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0021] [Embodiment 1] Hereinafter, the wiring member according to Embodiment 1 will be described. FIG. 1 is a perspective view showing a wiring member 30 according to Embodiment 1. FIG. 2 is an exploded perspective view showing the wiring member 30 according to Embodiment 1. FIG. 3 is a plan view schematically showing the relationship between the wiring member 30 and the movable device 20. In FIG. 1, the X direction is the front-rear direction of the vehicle, the Y direction is the width direction of the vehicle, and the Z direction is the height direction of the vehicle.

[0022] The wiring member 30 is connected to a movable device 20 provided in a vehicle. The wiring member 30 supplies power to the devices of the movable device 20, or sends signals to or from the devices of the movable device 20. The movable device 20 is electrically connected to a battery or an ECU (Electronic Control Unit) or the like via the wiring member 30. In the present embodiment, the movable device 20 is described as being a brake device 20. The movable device 20 may be a device other than the brake device 20. Also in the present embodiment, the brake device 20 is described as being a disc brake device. The brake device 20 may be a brake device 20 other than a disc brake device such as a drum brake device.

[0023] The braking device 20 is provided around the wheels of the vehicle. Around the wheels of the vehicle, the wheel is rotatably supported via the wheel support member 10. The braking device 20 includes a disc rotor 21, a brake caliper 22, a pair of brake pads 23, 24, and a brake piston 25, etc. The disc rotor 21 is supported by the wheel support member 10 so as to rotate integrally with the wheel. The brake caliper 22 is supported by the wheel support member 10 so as to straddle the disc rotor 21. The pair of brake pads 23, 24 are supported by the brake caliper 22 so as to be movable forward and backward with respect to the disc rotor 21. The disc rotor 21 is arranged so as to be positioned between the pair of brake pads 23, 24. The brake piston 25 is built into the brake caliper 22. By driving the brake piston 25, the disc rotor 21 is sandwiched between the pair of brake pads 23, 24, and the brake is actuated by the frictional force generated between the disc rotor 21 and the pair of brake pads 23, 24. The driving method of the brake piston 25 may be any driving method such as a wire drive type, a fluid drive type, or an electric motor type.

[0024] The wiring member 30 is connected to the movable part 22 in the movable device 20. In the present embodiment, the movable part 22 is described as being the brake caliper 22. The brake caliper 22 is a so-called floating caliper. The brake caliper 22 is movably supported by the wheel support member 10. The moving direction of the brake caliper 22 is a direction parallel to the direction in which the brake pads 23, 24 move forward and backward with respect to the disc rotor 21. The brake caliper 22 is interlocked with the brake pads 23, 24 and the brake piston 25. By driving the brake piston 25, the inner brake pad 23 moves in the direction of arrow A1 in FIG. 3 and is pressed against the inner surface of the disc rotor 21. In reaction, the brake caliper 22 and the outer brake pad 24 move in the direction of arrow A2 in FIG. 3 and are pressed against the outer surface of the disc rotor 21.

[0025] However, the brake caliper 22 may be fixed to the wheel support member 10. The brake caliper 22 may be a so-called opposed piston caliper or the like. In this case, the movable part 22 does not have to be the brake caliper 22. For example, the movable part may be the brake pads 23, 24 or the brake piston 25 or the like.

[0026] The wiring member 30 includes a connector 31, an electric wire 40, a protection member 50, and a connector cover 60.

[0027] The connector 31 is connected to the movable part 22. The connector 31 moves as the movable part 22 moves. In the present embodiment, the connector 31 is connected to a mating connector 26 provided on the brake caliper 22. The connector 31 includes, for example, a connector housing 32 and a connector terminal. The connector housing 32 holds the connector terminal in a fixed position. One end of the electric wire 40 is connected to the connector terminal. The other end of the connector terminal is connected to the mating connector terminal in the mating connector 26. In the connector 31, the portion that fits with the mating connector 26 is the front end portion, and the portion on the opposite side is the rear end portion. The front-rear direction of the connector 31 is parallel to the fitting direction between the connector 31 and the mating connector 26. Here, the fitting direction between the connector 31 and the mating connector 26 is parallel to the moving direction of the movable part 22. However, the fitting direction between the connector 31 and the mating connector 26 may be a direction that intersects the moving direction of the movable part 22.

[0028] The electric wire 40 extends from the rear end portion of the connector 31. The electric wire 40 is an insulated electric wire having a conductor core wire and an insulating coating. In the present embodiment, there are two electric wires 40, but the number of electric wires 40 may be one or three or more.

[0029] The protective member 50 covers the wire 40 at a position away from the connector 31 along the extending direction of the wire 40. Two wires 40 are covered by the protective member 50. In the present embodiment, the protective member 50 has an outer surface with a uniform shape continuously extending in the axial direction. For example, the protective member 50 may be a hose or a sheath. The hose is a member formed separately from the wire 40 by an elastic material such as rubber. The wire 40 is inserted from one end of the hose and extends out from the other end of the hose. The sheath is a member extruded around the wire 40 using a material such as resin.

[0030] The connector cover 60 covers the rear end portion of the connector 31, the end portion of the protective member 50, and the portion of the wire 40 between the connector 31 and the protective member 50. The connector cover 60 includes a first opening 63a and a second opening 64a. The connector 31 extends out of the connector cover 60 from the first opening 63a. The wire 40 extends out of the connector cover 60 from the second opening 64a. In the connector cover 60, the portion between the first opening 63a and the second opening 64a forms a passage portion through which the wire 40 passes.

[0031] In this example, the passage portion of the connector cover 60 has a bent passage portion 62. The bent passage portion 62 extends along the extending direction of the wire 40 while being bent. The bent passage portion 62 holds the wire 40 in a bent state. Here, the bent passage portion 62 holds the wire 40 in a state of being bent by more than 90 degrees. The bent passage portion 62 may hold the wire 40 in a state of being bent by 90 degrees or less than 90 degrees.

[0032] The passage portion of the connector cover 60 further has a first straight passage portion 63 and a second straight passage portion 64. The first opening 63a is provided at one end of the first straight passage portion 63. The second opening 64a is provided at one end of the second straight passage portion 64. The bent passage portion 62 connects the other end of the first straight passage portion 63 and the other end of the second straight passage portion 64. The first straight passage portion 63 and the second straight passage portion 64 extend in directions intersecting each other.

[0033] However, in the passage portion of the connector cover 60, the bent passage portion 62 may not be provided. For example, the passage portion of the connector cover 60 may extend linearly from the first opening portion 63a to the second opening portion 64a. Also, in the passage portion of the connector cover 60, either the first linear passage portion 63 or the second linear passage portion 64 may not be provided.

[0034] The connector cover 60 moves integrally with the connector 31. The connector 31 and the connector cover 60 are locked in the front-rear direction of the connector 31. The front-rear direction of the connector 31 is parallel to the extending direction of the first linear passage portion 63. An annular groove 33 is provided on the outer surface of the rear end portion of the connector housing 32. The annular groove 33 extends around an axis along the front-rear direction of the connector housing 32. As the inner surface of the annular groove 33, a rearward-facing surface and a forward-facing surface that face each other are formed along the front-rear direction of the connector housing 32. A fitting wall portion 63b that fits into the annular groove 33 is provided at the first opening portion 63a in the connector cover 60. When the connector 31 is pulled forward (in the direction of arrow A1 in FIG. 3 here), the forward-facing surface pushes the fitting wall portion 63b, so that the connector cover 60 moves integrally with the connector 31. When the connector 31 is pulled rearward (in the direction of arrow A2 in FIG. 3 here), the rearward-facing surface pushes the fitting wall portion 63b, so that the connector cover 60 moves integrally with the connector 31.

[0035] The edge of the protection member 50 fits into a portion closer to the second linear passage portion 64 among the second linear passage portion 64 or the bent passage portion 62. The protection member 50 extends linearly as much as possible within the connector cover 60. The protection member 50 may extend while bending along the bent passage portion 62 within the connector cover 60.

[0036] The connector cover 60 is movable relative to the protection member 50. A protruding wall portion 64b that protrudes toward the protection member 50 and narrows the second opening 64a is provided in the second opening 64a. The second opening 64a is formed in a shape (here, a circular shape) corresponding to the outer surface of the protection member 50. The second opening 64a is formed in a size (here, the same size) corresponding to the outer surface of the protection member 50. The protection member 50 is movable in a direction in which it is inserted into and removed from the connector cover 60 through the second opening 64a.

[0037] As shown in FIG. 2, the connector cover 60 includes a first cover component 65 and a second cover component 66. The first cover component 65 and the second cover component 66 each have a shape in which the connector cover 60 is split in half. The first cover component 65 and the second cover component 66 are combined to form the connector cover 60. The first cover component 65 and the second cover component 66 may be maintained in a combined state by locking between a locking portion provided on the first cover component 65 and a locked portion provided on the second cover component 66. The first cover component 65 and the second cover component 66 may be connected via a hinge so as to be openable and closable.

[0038] The overlapping dimension between the connector cover 60 and the protection member 50 in the extending direction of the electric wire 40 is equal to or greater than the moving amount in the movable portion 22. In FIG. 3, the dimension D1 is the overlapping dimension between the connector cover 60 and the protection member 50 in the extending direction of the electric wire 40. The dimension D1 is equal to or greater than the moving amount in the movable portion 22. The dimension D1 may be larger than the moving amount in the movable portion 22. When the dimension D1 is larger than the moving amount in the movable portion 22, the difference between the dimension D1 and the moving amount in the movable portion 22 is a margin. The margin may be, for example, from 1 mm to 20 mm.

[0039] In this embodiment, the movement amount of the movable part 22 includes the movement amount of the brake caliper 22 when the braking device 20 is in operation. In FIG. 3, the dimension D2 is the clearance between the disc rotor 21 and the brake pads 23 and 24 when the braking device 20 is not in operation, and is the movement amount of the brake caliper 22 when the braking device 20 is in operation. The dimension D1 is equal to or greater than the dimension D2. As described above, the inner brake pad 23 is pushed by the brake piston 25 and moves leftward in the drawing of FIG. 3 by the amount of dimension D2 and comes into contact with the disc rotor 21. By the reaction force, the outer brake pad 2 4 and the brake caliper 22 move rightward in the drawing of FIG. 3 by the amount of dimension D2. As a result, the connector 31 and the connector cover 60 also move rightward in the drawing of FIG. 3 by the amount of dimension D2. As a result, the protective member 50 moves relative to the connector cover 60 in a direction to come off from the connector cover 60. Even in this case, since the dimension D1 is equal to or greater than the dimension D2, the protective member 50 is suppressed from coming off from the connector cover 60.

[0040] At an intermediate portion along the extending direction of the wiring member 30, a fixed-position fixing portion 70 that is fixed at a fixed position with respect to the vehicle regardless of the presence or absence of the movement of the movable part 22 is provided. The portion on the connector 31 side of the fixed-position fixing portion 70 moves as the movable part 22 moves. As the movable part 22 moves, the position of the connector 31 changes with respect to the position of the fixed-position fixing portion 70. The fixed-position fixing portion 70 may be fixed to a member that supports the movable device 20, such as the wheel support member 10, for example.

[0041] In this embodiment, a band clip is attached and used as the fixed-position fixing portion 70. A clip other than a band clip such as a tape-winding clip or a bracket may be attached and used as the fixed-position fixing portion 70.

[0042] In the present embodiment, the fixed-position fixing portion 70 is provided at a portion of the protection member 50 that extends outside the connector cover 60. The position of the fixed-position fixing portion 70 may be any portion as long as it is a portion of the electric wire 40 that extends from the second opening 64a of the connector cover 60. For example, the fixed-position fixing portion 70 may be provided at a portion of the electric wire 40 that extends from the protection member 50. In this case, it is preferable that the electric wire 40 and the protection member 50 are fixed by tape winding or the like. The portion of the protection member 50 where the fixed-position fixing portion 70 is provided is fixed at a fixed position with respect to the vehicle regardless of the movement of the movable portion 22. In the protection member 50, the portion where the fixed-position fixing portion 70 is provided may be regarded as a fixed end, and the portion closer to the connector cover 60 than the fixed-position fixing portion 70 may be regarded as a free end.

[0043] The electric wire 40 may be immovable in the axial direction of the protection member 50 with respect to the protection member 50 at the portion where the fixed-position fixing portion 70 is provided. For example, the band portion of the band clip may tightly bind the electric wire 40 and the protection member 50, so that the electric wire 40 may be immovable in the axial direction of the protection member 50 with respect to the protection member 50. The electric wire 40 may be movable in the axial direction of the protection member 50 with respect to the protection member 50 at the portion where the fixed-position fixing portion 70 is provided. For example, the band portion of the band clip may loosely fasten the electric wire 40 and the protection member 50, so that the electric wire 40 may be movable in the axial direction of the protection member 50 with respect to the protection member 50.

[0044] In this embodiment, the movable device 20 includes wear members that wear out as the vehicle is used. As the wear members wear out, the amount of movement of the movable part 22 increases. In the braking device 20, the wear members are, for example, brake pads 23 and 24. There may be a wear limit set in advance for the wear members 23 and 24. The wear limit is a value set for the wear members 23 and 24 as a guide for replacing the wear members 23 and 24. In FIG. 3, the virtual line L is a line indicating the wear limit. In FIG. 3, the dimension D3 indicates the remaining amount of the wear members 23 and 24 up to the wear limit. Note that the line L indicating the wear limit may not be provided, and instead, a sensor or the like may be provided. When the wear members 23 and 24 reach the wear limit, the vehicle user may be notified that the wear members 23 and 24 have reached the wear limit.

[0045] With further reference to FIGS. 4 and 5, the relationship between the wiring member 30 and the movable device 20 when the wear members 23 and 24 are worn will be described. FIGS. 4 and 5 are plan views schematically showing the relationship between the wiring member 30 and the movable device 20 when the wear members 23 and 24 are worn. In FIG. 4, the virtual brake pads 23 and 24 indicate the state before wear, and the solid brake pads 23 and 24 indicate the state after wear. Also in FIG. 5, the members indicated by the virtual lines show the state before the movement by the adjustment mechanism 27, and the members indicated by the solid lines show the state after the movement by the adjustment mechanism 27.

[0046] In the braking device 20, when the brake pads 23 and 24 are worn, if no countermeasures are taken, the distance between the brake pads 23 and 24 and the disc rotor 21 will increase accordingly. Therefore, when the brake pads 23 and 24 are worn and the distance between the brake pads 23 and 24 and the disc rotor 21 increases, the piston stroke (dimension D2) increases, and the amount of movement in the movable part 22 increases.

[0047] Normally, in the braking device 20, the stroke of the brake piston 25 (the distance between the brake pads 23, 24 and the disc rotor 21) is adjusted by an adjusting mechanism 27 so as to be constant regardless of the wear amount of the brake pads 23, 24. When the brake pads 23, 24 wear, the inner brake pad 23 moves in the direction of arrow A1 in FIG. 4 and the outer brake pad 24 moves in the direction of arrow A2 in FIG. 4 by the amount of wear by the adjusting mechanism 27. Thereby, the distance between the pair of brake pads 23, 24 and the disc rotor 21 is kept constant. At this time, as shown in FIG. 5, the brake caliper 22 also moves in the direction of arrow A2 in FIG. 4 in conjunction with the brake pad 24. Therefore, the moving amount of the brake caliper 22 when the brake pads 23, 24 wear is the amount obtained by adding the moving amount of the position of the brake caliper 22 due to the wear of the brake pads 23, 24 to the predetermined stroke (dimension D2) of the brake piston 25. And the moving amount of the position of the brake caliper 22 caused by the future wear of the brake pads 23, 24 is expected to be the dimension D3 which is the remaining amount until the wear limit of the brake pads 23, 24. The sum of the dimension D2 and the dimension D3 is the moving amount in the movable part 22 when the wear members 23, 24 reach the wear limit. Since the dimension D1 is equal to or greater than the sum of the dimension D2 and the dimension D3, even if the brake pads 23, 24 wear to the wear limit in the future, the protective member 50 is less likely to come off from the connector cover 60.

[0048] In FIG. 3, the dimension D4 is the fitting dimension between the connector 31 and the mating connector 26. The fitting dimension between the connector 31 and the mating connector 26 is, for example, the amount inserted into the female connector among the male connectors. The dimension D1 is equal to or greater than the dimension D4. Thereby, even when the connector 31 is pulled during the fitting of the connector 31 and the mating connector 26, the protective member 50 is less likely to come off from the connector cover 60.

[0049] <Effects, etc.> According to the wiring member 30 configured as described above, since the overlapping dimension D1 between the connector cover 60 and the protection member 50 in the extending direction of the electric wire 40 is equal to or greater than the moving amount (here, the dimension D2 or the sum of the dimension D2 and the dimension D3) of the movable device 20, even if the connector 31 and the connector cover 60 move as the movable device 20 moves, the protection member 50 is prevented from falling off from the connector cover 60.

[0050] Also, at an intermediate portion along the extending direction of the wiring member 30, a fixed-position fixing portion 70 that is fixed at a fixed position with respect to the vehicle regardless of the movement of the movable device 20 is provided. Thereby, even if the portion on the connector 31 side relative to the fixed-position fixing portion 70 moves, the protection member 50 is prevented from falling off from the connector cover 60.

[0051] Also, the fixed-position fixing portion 70 is provided at a portion of the protection member 50 that extends outside the connector cover 60. Thereby, the portion of the protection member 50 that extends outside the connector cover 60 is fixed at a fixed position with respect to the vehicle regardless of the movement of the movable device 20.

[0052] Also, the overlapping dimension D1 between the connector cover 60 and the protection member 50 in the extending direction of the electric wire 40 is equal to or greater than the moving amount (here, the sum of the dimension D2 and the dimension D3) of the movable portion 22 when the wear members 23 and 24 reach the wear limit. Thereby, even if the connector 31 and the connector cover 60 move when the wear members 23 and 24 reach the wear limit, the protection member 50 is prevented from falling off from the connector cover 60.

[0053] Also, the overlapping dimension D1 between the connector cover 60 and the protection member 50 in the extending direction of the electric wire 40 is equal to or greater than the fitting dimension D4 between the connector 31 and the mating connector 26. Thereby, even if the connector 31 and the connector cover 60 move when the connector 31 is connected to the mating connector 26, the protection member 50 is prevented from falling off from the connector cover 60.

[0054] [Embodiment 2] The wiring member according to Embodiment 2 will be described. FIG. 6 is a perspective view showing the wiring member 130 according to Embodiment 2. FIG. 7 is an exploded plan view showing the wiring member 130 according to Embodiment 2. In the description of the present embodiment, the same components as those described so far are denoted by the same reference numerals and their description is omitted.

[0055] In the wiring member 130, the shape of the connector cover 160 is different from the shape of the connector cover 60 in the wiring member 30. Specifically, the connector cover 160 has a connector cover body 61 and a protrusion 67. The protrusion 67 protrudes from the connector cover body 61 toward the outer surface of the protection member 50. The protrusion 67 is in contact with the outer surface of the protection member 50 and at least one of the protection member 50 and the protrusion 67 is elastically deformed. As a result, it becomes difficult for the protection member 50 to fall off from the connector cover 60.

[0056] The connector cover body 61 is a portion forming a passage portion, and has a bent passage portion 62, a first straight passage portion 63, and a second straight passage portion 164. The protrusion 67 is provided in the second straight passage portion 164. In the present embodiment, a pair of protrusions 67 are provided. The protection member 50 is positioned between the pair of protrusions 67. The pair of protrusions 67 sandwich the protection member 50.

[0057] In the present embodiment, a hole 69 is formed around a connecting portion 68 between the connector cover body 61 and the protrusion 67 in the connector cover 160. The protrusion 67 can be elastically deformed in the inner and outer directions of the connector cover 160 via the connecting portion 68. As a result, when the protection member 50 inserted into the connector cover 160 comes into contact with the protrusion 67, the protrusion 67 can be elastically deformed, making it easier for the protection member 50 to be inserted into the connector cover 160. However, the protrusion 67 may be less elastically deformable than the protection member 50.

[0058] The hole 69 is also used as a die hole for punching the upper and lower molds for forming the first cover component 65 while providing the protrusion 67 and the connecting portion 68.

[0059] The tip of the protrusion 67 extends along the outer surface of the protection member 50. A guide surface is provided on the connection portion 68 side rather than the tip of the protrusion 67. The guide surface inclines away from the protection member 50 from the tip of the protrusion 67 toward the second opening 64a.

[0060] A drain hole 69 is formed in the connector cover 60. Thereby, the accumulation of water inside the connector cover 60 is suppressed. In the present embodiment, the hole 69 around the connection portion 68 between the connector cover main body 61 and the protrusion 67 serves as the drain hole 69.

[0061] In the present embodiment, the second straight passage portion 164 is formed to be longer than the second straight passage portion 64. Thereby, the overlapping dimension D1 between the connector cover 160 and the protection member 50 in the extending direction of the electric wire 40 becomes larger. However, in the connector cover 160, the second straight passage portion 164 does not necessarily have to be long.

[0062] Also, in the present embodiment, a restricting wall portion 64c is provided in a portion of the second straight passage portion 164 closer to the bending passage portion 62 than the protrusion 67. The restricting wall portion 64c protrudes toward the inside of the second straight passage portion 164. The restricting wall portion 64c is formed smaller than the protection member 50. The tip surface of the protection member 50 abuts against the restricting wall portion 64c, and the insertion into the connector cover 160 more than that is suppressed. However, in the connector cover 160, the restricting wall portion 64c does not necessarily have to be provided.

[0063] In the present embodiment, the connector cover 60 has been described as including both the protrusion 67 and the drain hole 69, but this is not an essential configuration. The connector cover 60 may include only one of the protrusion 67 and the drain hole 69.

[0064] In addition, each configuration described in the above embodiments and each modification can be appropriately combined as long as they do not conflict with each other.
