Description

Technical Field

[0001] The present disclosure relates to a connector. Background Art

[0002] Conventionally, a connector mounted on a box that houses equipment mounted on a vehicle has a plurality of electric wires, a plurality of terminals electrically connected to the electric wires, and a connector housing that holds the plurality of terminals. The plurality of electric wires have metal wires. Each terminal has a connection portion and an electric wire connection portion that is electrically connected to the metal wire of the electric wire. The connection portion is inserted into a mounting hole provided in the box.

[0003] For example, the connector housing of the connector described in Patent Document 1 has: a maintenance cover having a terminal insertion hole; and a split housing having a maintenance hole for inserting the maintenance cover and a wire insertion hole. A plurality of terminals are assembled to the maintenance cover and the split housing with the connection portions protruding from the terminal insertion holes to the outside. The electric wires connected to the respective terminals are led out of the connector housing through the wire insertion holes. Further, the connection portion between the terminal and the electric wire is disposed in the internal space of the split housing and in a space surrounded by the maintenance cover and the split housing. A sealing member is disposed between the outer peripheral surface of the maintenance cover and the inner peripheral surface of the maintenance hole, and the sealing member suppresses water such as rainwater from entering the inside of the split housing through the maintenance hole.

[0006] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2015-5432 Summary of the Invention

[0007] Problems to be Solved by the Invention

[0008] However, since a vehicle travels in various environments, the water that is about to enter the inside of the split housing through the maintenance hole sometimes contains salt. When the water containing salt comes into contact with the sealing member disposed between the outer peripheral surface of the maintenance cover and the inner peripheral surface of the maintenance hole, the annual deterioration of the sealing member is promoted due to the salt contained in the water. As a result, the sealing performance of the sealing member is reduced, and water enters the inside of the split housing through the maintenance hole. As a result, it is possible that water adheres to the connection portion between the terminal and the electric wire.

[0009] Further, in the above-described connector, since the connection portion between the terminal and the electric wire is disposed in the internal space of the split housing, condensation may occur at the connection portion between the terminal and the electric wire. That is, it is possible that water adheres to the connection portion between the terminal and the electric wire.

[0010] When the terminal and the metal wire that are electrically connected to each other are made of different types of metals, when water adheres to the connection portion between the terminal and the electric wire, dissimilar metal corrosion of the connection portion may occur.

[0011] An object of the present disclosure is to provide a connector capable of suppressing dissimilar metal corrosion at a connection portion between a terminal and a wire.

[0012] Solution to the problem

[0013] The connector of the present disclosure includes: a plurality of wires having metal wires; a plurality of terminals having a connection portion inserted into a mounting hole and a wire connection portion electrically connected to the metal wire, the mounting hole being provided in a box for housing equipment mounted on a vehicle; and a connector housing that holds the plurality of terminals, the connected terminals and the metal wires being made of different kinds of metals, the connector housing protruding the connection portion to the outside and burying the electrical connection portion between the terminals and the metal wires, and further having a box-side seal groove on an outer wall surface of the connector housing, and a box-side seal member for sealing between the outer wall surface of the connector housing and the inner circumferential surface of the mounting hole is disposed in the box-side seal groove.

[0014] Advantageous effects of the invention

[0015] According to the connector of the present disclosure, dissimilar metal corrosion at a connection portion between a terminal and a wire can be suppressed. Description of the drawings

[0032] [Description of Embodiments of the Present Disclosure]

[0033] First, embodiments of the present disclosure will be listed and described.

[0034] The connector of the present disclosure,

[0035] (1) includes: a plurality of electric wires having metal wires; a plurality of terminals having a connection portion inserted into a mounting hole and a wire connection portion electrically connected to the metal wire, the mounting hole being provided in a box for housing equipment mounted on a vehicle; and a connector housing holding the plurality of terminals, the connected terminals and the metal wires being made of different kinds of metals, the connector housing protruding the connection portion to the outside and burying the electrical connection portion between the terminals and the metal wires, and further having a box-side seal groove on an outer wall surface of the connector housing, and a box-side seal member for sealing between the outer wall surface of the connector housing and the inner peripheral surface of the mounting hole is disposed in the box-side seal groove.

[0036] According to the above-described manner, the electrical connection portion between the terminals and the metal wires is buried in the connector housing. Therefore, water attachment to the connection portion between the terminals and the metal wires can be suppressed by the connector housing. Therefore, dissimilar metal corrosion of the connection portion between the terminals and the electric wires can be suppressed.

[0037] (2) Preferably, there is a shielding case covering the outside of the connector housing. The shielding case has an exposed port that connects the inside and outside of the shielding case. The connecting portion protrudes from the exposed port to the outside of the shielding case. The connector housing has a shielding side seal groove on the outer wall surface of the connector housing, and a shielding side seal member for sealing between the outer wall surface of the connector housing and the inner wall surface of the shielding case is arranged in the shielding side seal groove. When the protruding direction of the connecting portion from the connector housing is set as the first direction, when viewed from the first direction, the shielding side seal groove is provided between the portion of the outer wall surface of the connector housing where the connecting portion protrudes and the portion of the outer wall surface of the connector housing where the electric wire is led out.

[0038] According to the above method, the shielding side seal member can be used to prevent water that has entered the inside of the shielding case from the exposed port from reaching the portion of the outer wall surface of the connector housing where the electric wire is led out. Therefore, it is possible to further prevent the water from adhering to the connection portion between the terminal and the metal wire. As a result, it is possible to further prevent the dissimilar metal corrosion of the connection portion between the terminal and the electric wire.

[0039] (3) Preferably, when the protruding direction of the connecting portion from the connector housing is set as the first direction, a plurality of the electric wires are led out from the connector housing along a second direction that intersects the first direction, and the lead-out positions on the outer wall surface of the connector housing where the plurality of the electric wires are respectively led out are arranged along a third direction that intersects the first direction and intersects the second direction.

[0040] According to the above method, each electric wire is led out to the outside of the connector housing along the second direction that intersects the first direction, which is the protruding direction of the connecting portion from the connector housing. Therefore, compared with the case where each electric wire is led out from the connector housing along the first direction, the connector housing can be miniaturized in the first direction. Further, the plurality of lead-out positions on the outer wall surface of the connector housing are arranged along the third direction that intersects the first direction and intersects the second direction. Therefore, compared with the case where the plurality of lead-out positions are arranged along the first direction, the connector housing can be further miniaturized in the first direction. As a result, since the connector housing can be miniaturized, the connector can be miniaturized.

[0041] (4) Preferably, a plurality of the connecting portions are arranged in the second direction, the lead-out position is located on one side of the plurality of the connecting portions in the second direction, and the electric wire connected to the electric wire connecting portion of the terminal having the connecting portion located at the position farthest from the lead-out position in the second direction among the plurality of terminals has a longer length of the portion buried in the connector housing than the electric wire connected to the electric wire connecting portion of the terminal having the connecting portion located at the position closest to the lead-out position in the second direction among the plurality of terminals.

[0042] According to the above method, compared with the inside of the connector housing, when the length of the wire connected to the terminal having the connection portion located at the position farthest from the lead-out position in the second direction is equal to or less than the length of the wire connected to the terminal having the connection portion located at the position closest to the lead-out position in the second direction, the terminal having the connection portion located at the position farthest from the lead-out position in the second direction can be shortened in the second direction. Therefore, among the terminals having the connection portion located at the position farthest from the lead-out position in the second direction, the usage amount of the material of the terminal, which is more expensive than the wire, can be suppressed to be less. Therefore, the manufacturing cost of the connector can be reduced.

[0043] (5) Preferably, a first terminal, which is one of the plurality of terminals, has a bent portion disposed inside the connector housing and bent, and portions of both sides of the bent portion in the first terminal that do not include the connection portion extend along a fourth direction intersecting the first direction.

[0044] According to the above method, the first terminal can be miniaturized in the first direction. Therefore, it is easy to further miniaturize the connector housing holding the first terminal in the first direction.

[0045] (6) Preferably, the first terminal has the bent portion between the connection portion and the wire connection portion, and a portion of the first terminal from the bent portion to the wire connection portion side extends along the fourth direction.

[0046] According to the above method, compared with the case where the bent portion is not provided in the first terminal, the wire connection portion can be closer to the connection portion in the first direction. Therefore, the distance in the first direction between the first terminal and the wire connection portion can be shortened, and thus it is easy to further miniaturize the first terminal in the first direction. Therefore, it is easy to further miniaturize the connector housing holding the first terminal in the first direction.

[0047] (7) Preferably, the wire of the metal wire connected to the wire connection portion of the second terminal, which is different from the first terminal among the plurality of terminals, extends from the wire connection portion along the second direction to the lead-out position on the outer wall surface of the connector housing where the wire is led out.

[0048] According to the above method, the wire of the metal wire connected to the wire connection portion of the second terminal extends linearly along the second direction inside the connector housing. Therefore, compared with the case where the wire is complicatedly bent or folded inside the connector housing, the space occupied by the wire inside the connector housing can be reduced. Therefore, the connector housing can be further miniaturized. In addition, when forming the connector housing, the wire does not have to be held in a complicated shape, so it is easy to form the connector housing holding the second terminal.

[0049] (8) Preferably, the fourth direction extends along the third direction.

[0050] According to the above manner, compared with the case where the fourth direction intersects the third direction, it is easier to reduce the space occupied by the first terminal and the plurality of electric wires inside the connector housing in the first direction. Therefore, the connector housing can be further miniaturized. In addition, when the fourth direction is along the third direction, a plurality of bent portions may not be provided on the first terminal. Therefore, the complication of the shape of the first terminal can be suppressed.

[0051] (9) Preferably, the connecting portions of the plurality of terminals are arranged in a direction perpendicular to the third direction.

[0052] According to the above manner, compared with the case where the direction in which the connecting portions of the plurality of terminals are arranged is not perpendicular to the third direction, the connector housing can be miniaturized in the direction in which the connecting portions of the plurality of terminals are arranged.

[0053] (10) Preferably, the terminal is made of copper or a copper alloy, and the metal wire is made of aluminum or an aluminum alloy.

[0054] According to the above manner, the dissimilar metal corrosion of the connecting portion between the terminal made of copper or a copper alloy and the metal wire made of aluminum or an aluminum alloy can be suppressed. And a terminal with excellent conductivity can be provided. In addition, the electric wire can be made lighter.

[0055] [Details of the Embodiment of the Present Disclosure]

[0056] The following will describe a specific example of the connector of the present disclosure while referring to the attached Figure 1 The present invention is not limited to these examples, but is shown by the claims, and intends to include all changes within the meaning and scope equivalent to the claims.

[0057] Hereinafter, an embodiment of the connector will be described.

[0058] Figures 1 to 3 The connector 30 of the present embodiment shown is used to electrically connect the device 21 mounted on an automotive vehicle and a battery (not shown). In the present embodiment, the device 21 is an inverter 22. The connector 30 is mounted on a conductive box body 23 that houses the inverter 22.

[0059] (Box body 23)

[0060] The housing 23 is made of a conductive metal material. The housing 23 has a box-shaped housing main body 24 that houses the inverter 22, and a mounting portion 25 that is provided integrally with the housing main body 24 and protrudes to the outside of the housing main body 24. The mounting portion 25 is formed in a cylindrical shape by having a mounting hole 26 that penetrates the mounting portion 25. The mounting hole 26 communicates the inside and outside of the housing 23. In addition, the shape of the mounting hole 26 as viewed in the penetrating direction forms a flat shape having a long side direction and a short side direction.

[0061] Here, the Y direction in the figure is the protruding direction of the connecting portions 61 and 71 from the connector housing 35 described later. The positive Y direction is the direction in the Y direction from the base end toward the tip end of the connecting portions 61 and 71. The negative Y direction is the direction in the Y direction from the tip end toward the base end of the connecting portions 61 and 71. In addition, the base end of the connecting portions 61 and 71 is the end portion closer to the connector housing 35 among the two ends of the connecting portions 61 and 71 in the protruding direction of the connecting portions 61 and 71 from the connector housing 35. The tip end of the connecting portions 61 and 71 is the end portion farther from the connector housing 35 among the two ends of the connecting portions 61 and 71 in the protruding direction of the connecting portions 61 and 71 from the connector housing 35. In addition, the X direction is a direction that intersects the Y direction, and is the direction in which the electric wires 33 and 34 described later are led out from the connector housing 35. As Figure 5 shown, the positive X direction is the direction in the X direction from the lead-out positions P1 and P2 where the electric wires 33 and 34 are respectively led out from the outer wall surface of the connector housing 35 toward the inside of the connector housing 35. The negative X direction is the direction in the X direction from the inside of the connector housing 35 toward the lead-out positions P1 and P2. In the present embodiment, the X direction and the Y direction are perpendicularly crossed. In addition, the Z direction is a direction that intersects the Y direction and intersects the X direction. As Figure 11 shown, when viewing the connector housing 35 from the Y direction, in the case where the lead-out positions P1 and P2 are located on the right side of the connecting portions 61 and 71, the upward direction in the Z direction is the positive Z direction, and the downward direction is the negative Z direction. In the present embodiment, the Z direction is perpendicularly crossed with the Y direction and perpendicularly crossed with the X direction. Incidentally, in the figure, the positive Y direction, the positive X direction, and the positive Z direction are illustrated with arrows.

[0062] In addition, in the present embodiment, the Y direction corresponds to the "first direction" in [Description of the Embodiment of the Present Disclosure]. In addition, the X direction corresponds to the "second direction" in [Description of the Embodiment of the Present Disclosure]. In addition, the Z direction corresponds to the "third direction" in [Description of the Embodiment of the Present Disclosure]. In addition, in the present embodiment, the Z direction corresponds to the "fourth direction" in [Description of the Embodiment of the Present Disclosure].

[0063] As Figure 1 and Figure 2As shown, the connector 30 can be mounted on the box body 23 in any orientation according to the posture of the mounting portion 25. In the present embodiment, the description of the connector 30 will be made with the penetration direction of the mounting hole 26 set as the front-rear direction. In Figure 1 it, the Y direction is consistent with the penetration direction of the mounting hole 26. Also, the direction from the outer opening of the mounting hole 26 towards the inner opening is substantially consistent with the positive Y direction. Further, the direction from the inner opening of the mounting hole 26 towards the outer opening is substantially consistent with the negative Y direction. That is, the outer opening side of the mounting hole 26 is the rear side, and the inner opening side is the front side. In addition, the X direction is perpendicular to the penetration direction of the mounting hole 26 and is substantially consistent with the direction along the long side direction of the mounting hole 26. Also, the right side when viewing the mounting hole 26 from the outer opening side of the mounting hole 26 is substantially consistent with the positive X direction. Further, the left side in this case is substantially consistent with the negative X direction. Furthermore, the Z direction is perpendicular to the penetration direction of the mounting hole 26 and is substantially consistent with the direction along the short side direction of the mounting hole 26. Also, the upper side is substantially consistent with the positive Z direction. Further, the lower side is substantially consistent with the negative Z direction. Hereinafter, when describing the direction of the connector 30, the Y direction, the X direction, and the Z direction will be used.

[0064] An insertion portion 27 extending along the periphery of the outer opening of the mounting hole 26 is provided on the top surface of the mounting portion 25. The insertion portion 27 is formed integrally with the mounting portion 25. The insertion portion 27 protrudes from the top surface of the mounting portion 25 in the negative Y direction and is formed in a ring shape.

[0065] The box body 23 has fixing holes 28 for fixing the connector 30 to the box body 23. In the present embodiment, the box body 23 has two fixing holes irectly above the mounting hole 26 and on both sides in the X direction of the mounting hole 26 when viewed from the penetration direction of the mounting hole 26. Each fixing hole 28 is a female threaded hole.

[0066] (Configuration of the connector 30)

[0067] As Figure 3 and Figure 4 shown, the connector 30 includes: a plurality of terminals 31, 32 electrically connected to the device 21; wires 33, 34 electrically connected to the terminals 31, 32; a connector housing 35 holding the terminals 31, 32; and a shielding case 36 covering the outside of the connector housing 35.

[0068] (Configuration of the connector housing 35)

[0069] As Figure 5As shown, the connector housing 35 has a main body portion 41 and a terminal holding portion 42 that projects from the main body portion 41. The connector housing 35 is made of an insulating resin material. As the resin material of the connector housing 35, for example, polybutylene terephthalate (PBT) can be used. Additionally, the resin material of the connector housing 35 can also be a resin material containing fillers such as glass fiber. The main body portion 41 and the terminal holding portion 42 are formed integrally.

[0070] The shape of the main body portion 41 as viewed from the Y direction forms a rectangle. In addition, by "forming a rectangle", it does not necessarily have to be a strict rectangle, as long as the outer shape of the main body portion 41 as viewed from the Y direction forms a substantially rectangular shape. That is, assuming that even if there are concavities and convexities on any side, or any side is gently curved, or the intersecting sides do not form a perpendicular to each other when viewing the outer shape of the main body portion 41 from the Y direction, it still forms a rectangle.

[0071] In the present embodiment, the main body portion 41 forms a rectangle that is long in the X direction as viewed from the Y direction. The main body portion 41 has a holding portion 43 and two wire holding portions 44, 45 that are formed integrally with the holding portion 43. The outer shape of the holding portion 43 as viewed from the Y direction forms a rectangle. The wire holding portions 44, 45 project along the X direction from the end portion in the opposite direction of X in the holding portion 43. The two wire holding portions 44, 45 are arranged in the Z direction. Each wire holding portion 44, 45 is formed in a cylindrical shape extending in the X direction. The end faces in the opposite direction of X of the two wire holding portions 44, 45 are perpendicular to the X direction, and their positions in the X direction are the same.

[0072] On the outer peripheral surfaces of the respective wire holding portions 44, 45, first sealing grooves 46, 47 are recessed. The first sealing grooves 46, 47 correspond to "shield side sealing grooves". The first sealing groove 46 is formed in an annular shape that surrounds the outer periphery of the wire holding portion 44 and extends along the circumferential direction of the wire holding portion 44 over the entire circumference of the wire holding portion 44. The first sealing groove 47 is formed in an annular shape that surrounds the outer periphery of the wire holding portion 45 and extends along the circumferential direction of the wire holding portion 45 over the entire circumference of the wire holding portion 45. The first sealing grooves 46, 47 extend along the Z direction as viewed from the Y direction, and extend along the Y direction as viewed from the Z direction.

[0073] As Figure 4 and Figure 7As shown, wire-side seal members 48 and 49 are respectively arranged in the first seal grooves 46 and 47. The wire-side seal members 48 and 49 correspond to the "shield-side seal members". The wire-side seal members 48 and 49 are made of a resin material that has elasticity and can be in liquid-tight contact with the outer peripheral surfaces of the wire holding portions 44 and 45. In addition, the wire-side seal members 48 and 49 are formed in a ring shape. In the present embodiment, the wire-side seal members 48 and 49 are rubber rings. The wire-side seal member 48 is inserted into the wire holding portion 44 and arranged in the first seal groove 46. And the wire-side seal member 48 is positioned in the X direction with respect to the connector housing 35 by the inner side surface of the first seal groove 46. In addition, the wire-side seal member 49 is inserted into the wire holding portion 45 and arranged in the first seal groove 47. And the wire-side seal member 49 is positioned in the X direction with respect to the connector housing 35 by the inner side surface of the first seal groove 47. The wire-side seal members 48 and 49 extend along the Z direction when viewed from the Y direction, and extend along the Y direction when viewed from the Z direction.

[0074] As Figure 5 and Figure 7 shown, the width of the main body portion 41 in the Z direction becomes the largest at the X-direction end portions on the wire holding portions 44 and 45 sides in the main body portion 41. When measuring the width of the main body portion 41 in the Z direction, it is assumed that the width of the chamfered portion at the end of the main body portion 41 is ignored. In the present embodiment, regarding the width of the main body portion 41 in the Z direction, the width D1 of the portion between the top surfaces of the wire holding portions 44 and 45 in the opposite direction of X and the first seal grooves 46 and 47 is the largest. In addition, in the present embodiment, although the width of the main body portion 41 in the Z direction has some steps or unevenness, it is substantially constant along the X direction.

[0075] In addition, the width of the main body portion 41 in the Y direction becomes the largest at the X-direction end portions on the wire holding portions 44 and 45 sides in the main body portion 41. When measuring the width of the main body portion 41 in the Y direction, it is assumed that the width of the chamfered portion at the end of the main body portion 41 is ignored. In the present embodiment, regarding the width of the main body portion 41 in the Y direction, the width D2 of the portion between the top surfaces of the wire holding portions 44 and 45 in the opposite direction of X and the first seal grooves 46 and 47 is the largest.

[0076] As Figure 5 and Figure 8As shown, the terminal holding portion 42 protrudes in the positive Y direction from the front surface of the main body portion 41. Specifically, the terminal holding portion 42 is integrally provided at a position near the lower end portion in the front surface of the main body portion 41 and at a position near the end portion in the X direction on the side opposite to the wire holding portions 44 and 45 in the front surface of the main body portion 41. The terminal holding portion 42 has a flange portion 51 that protrudes in the positive Y direction from the front surface of the main body portion 41, and a support portion 52 that further protrudes in the positive Y direction from the flange portion 51. The flange portion 51 and the support portion 52 are formed integrally.

[0077] The flange portion 51 is formed in a plate shape with the Y direction as the thickness direction. The flange portion 51 covers a portion of the front surface of the main body portion 41 near the lower end portion and near the end portion in the X direction on the side opposite to the wire holding portions 44 and 45 in the front surface of the main body portion 41. In addition, the lower end portion of the flange portion 51 protrudes downward from the main body portion 41, that is, in the negative Z direction. The X-direction position of the end portion in the positive X direction of the flange portion 51 is the same as the X-direction position of the end portion in the positive X direction of the main body portion 41. On the other hand, the end portion in the negative X direction of the flange portion 51 is located at a position closer to the center in the X direction of the main body portion 41 than the end portion in the negative X direction of the main body portion 41. In addition, the end portion in the negative X direction of the flange portion 51 forms an arc shape when viewed from the Y direction.

[0078] The support portion 52 is formed in a substantially columnar shape that protrudes in the positive Y direction from the central portion of the flange portion 51. The support portion 52 forms a shape with different lengths in two orthogonal directions when viewed from the Y direction, that is, a shape having a long side direction and a short side direction. In the present embodiment, the support portion 52 is formed in a shape with the X direction as the long side direction and the Y direction as the short side direction. And the support portion 52 forms a shape that is long in the X direction when viewed from the Y direction, that is, a rounded rectangle. The lower end of the support portion 52 is located below the lower end of the main body portion 41. In addition, when viewed from the Y direction, the support portion 52 is accommodated between the two ends in the X direction of the holding portion 43.

[0079] A second sealing groove 53 is recessed in the outer peripheral surface of the support portion 52. The second sealing groove 53 corresponds to the "box-side sealing groove". The second sealing groove 53 is formed in a ring shape that extends over the entire circumference of the support portion 52 so as to surround the outer periphery of the support portion 52. The second sealing groove 53 extends along the Z direction when viewed from the X direction, and extends along the Y direction when viewed from the Z direction.

[0080] A housing-side seal member 54 is disposed in the second seal groove 53. The housing-side seal member 54 is made of a resin material having elasticity and capable of being in liquid-tight contact with the outer peripheral surface of the support portion 52. In addition, the housing-side seal member 54 is formed in a ring shape. In the present embodiment, the housing-side seal member 54 is a rubber ring. The housing-side seal member 54 is inserted over the support portion 52 and disposed within the second seal groove 53. And, the housing-side seal member 54 is positioned in the Y direction with respect to the connector housing 35 by the inner side surface of the second seal groove 53.

[0081] (Configuration of terminals 31 and 32)

[0082] As Figure 5 and Figure 6 shown, the connector housing 35 holds two terminals, the first terminal 31 and the second terminal 32. In addition, in Figure 6 and Figures 9 to 11 , the connector housing 35 is schematically illustrated in phantom with a double-dashed line, and the outer shape of the connector housing 35 is schematically illustrated in a simplified manner. The first terminal 31 and the second terminal 32 are made of a conductive metal material. As the material of the first terminal 31 and the second terminal 32, for example, metals with excellent conductivity such as copper, copper alloy, aluminum, and aluminum alloy can be used. In addition, in the present embodiment, the first terminal 31 and the second terminal 32 are formed by performing stamping on a plate made of copper or copper alloy.

[0083] As Figure 6 and Figures 9 to 11 shown, the first terminal 31 has: a first connection portion 61 that is electrically connected to the other-side terminal 201 provided in the inverter 22; a first wire connection portion 62 that is electrically connected to the first wire 33; and a first connecting portion 63 that connects the first connection portion 61 and the first wire connection portion 62. In the present embodiment, the first connection portion 61 is provided at one end of the first terminal 31, and the first wire connection portion 62 is provided at the other end of the first terminal 31. The connector housing 35 holds the first terminal 31 in a state where the first connection portion 61 is exposed to the outside of the connector housing 35 by embedding the first wire connection portion 62 and the first connecting portion 63 therein. That is, the first terminal 31 is insert-molded into the connector housing 35.

[0084] The first connecting portion 61 is formed in a plate shape. The first connecting portion 61 protrudes from the top surface of the supporting portion 52 of the terminal holding portion 42 to the outside of the connector housing 35 in the Y direction. In the present embodiment, the protruding direction of the first connecting portion 61 is the positive Y direction. Incidentally, in the first terminal 31, the portion that protrudes from the connector housing 35 to the outside of the connector housing 35 for electrical connection with the mating terminal 201 is the first connecting portion 61. The first connecting portion 61 is held by the terminal holding portion 42 in such a manner that the plate thickness direction is along the Z direction. A first connection hole 64 that penetrates the first connecting portion 61 in the plate thickness direction is formed at the top end portion of the first connecting portion 61 that protrudes from the top surface of the supporting portion 52.

[0085] The first terminal 31 has a bent portion 65 formed by bending the first terminal 31 between the first connecting portion 61 and the first wire connecting portion 62. That is, the bent portion 65 is provided in the first connecting portion 63. The bent portion 65 is a portion formed by plastically deforming a metal plate material constituting the first terminal 31 by bending processing or the like. By having the bent portion 65, the portion of the first terminal 31 on the side of the first wire connecting portion 62 relative to the bent portion 65 extends in a different direction from the portion of the first terminal 31 on the side of the first connecting portion 61 relative to the bent portion 65. Specifically, the portion of the first terminal 31 from the end portion on the first connecting portion 61 side to the bent portion 65 extends along the Y direction, and the plate thickness direction is along the Z direction. And, the portions on both sides of the bent portion 65 in the first terminal 31 that do not include the first connecting portion 61, that is, the portion of the first terminal 31 from the bent portion 65 to the end portion on the first wire connecting portion 62 side extends along the Z direction, and the plate thickness direction is along the Y direction. Therefore, the portion of the first terminal 31 from the bent portion 65 to the end portion on the first wire connecting portion 62 side is perpendicular to the portion of the first terminal 31 from the end portion on the first connecting portion 61 side to the bent portion 65.

[0086] The bent portion 65 is buried inside the connector housing 35. And, the portion of the first terminal 31 from the bent portion 65 to the end portion on the first wire connecting portion 62 side is also buried inside the connector housing 35.

[0087] The first wire connecting portion 62 has a pair of cylindrical pieces 66. The first wire 33 connected to the first wire connecting portion 62 has a core wire 81 and an insulating coating portion 82 that covers the outer periphery of the core wire 81 over the entire circumference. The core wire 81 may be a single wire composed of a single conductive metal wire or a stranded wire composed of a plurality of conductive metal wires. That is, the core wire 81 corresponds to the "metal wire". As the material of the core wire 81, for example, metals with excellent conductivity such as copper, copper alloy, aluminum, and aluminum alloy can be used. In the present embodiment, the core wire 81 is composed of a metal different from the material type of the first terminal 31 and is composed of aluminum or aluminum alloy.

[0088] At the end of the first wire 33 connected to the first wire connection portion 62, the insulating coating portion 82 is removed to expose the core wire 81. The portion of the exposed core wire 81 at the end of the first wire 33 is wrapped by a pair of cylindrical pieces 66 and tightened together with the cylindrical pieces 66, thereby being crimped to the first wire connection portion 62. Thus, the core wire 81 of the first wire 33 is electrically connected to the first wire connection portion 62. That is, the first wire 33 is electrically connected to the first wire connection portion 62. In addition, the end of the first wire 33 connected to the first wire connection portion 62 is disposed on the rear side, that is, the Y reverse direction side, with respect to the flat plate portion of the first terminal 31 from the bent portion 65 to the end on the first wire connection portion 62 side. The electrically connected portion of the first terminal 31 and the first wire 33 is buried inside the connector housing 35. That is, the connector housing 35 holds the electrically connected portion of the first terminal 31 and the first wire 33 inside.

[0089] The first wire 33 is led out from the first wire connection portion 62 through the inside of the connector housing 35 to the outside of the connector housing 35. In the present embodiment, the first wire 33 extends upward to the wire holding portion 44 inside the holding portion 43 in the X reverse direction from the first wire connection portion 62, and then further penetrates through the wire holding portion 44 along the X direction to be led out to the outside of the connector housing 35. That is, the first wire 33 is led out from the main body portion 41 to the outside of the connector housing 35. Further, the first wire 33 is led out to the outside of the connector housing 35 along the X direction.

[0090] The first lead-out position P1 where the first wire 33 is led out from the connector housing 35 to the outside is located on the end face in the X reverse direction of the wire holding portion 44. That is, the position of the first lead-out position P1 in the X direction is the same as the position of the end face in the X reverse direction of the wire holding portion 44 in the X direction. In addition, the position of the first lead-out position P1 in the Z direction is the same as the position of the first wire connection portion 62 in the Z direction. Further, the position of the first lead-out position P1 in the Y direction is substantially the same as the position of the end of the first wire 33 connected to the first wire connection portion 62. The first wire 33 does not bend or fold inside the connector housing 35, but linearly extends from the first wire connection portion 62 along the X direction to the first lead-out position P1.

[0091] The second terminal 32 has: a second connection portion 71 that is electrically connected to the opposing terminal 202 provided in the inverter 22; a second wire connection portion 72 that is electrically connected to the second wire 34; and a second coupling portion 73 that couples the second connection portion 71 and the second wire connection portion 72. In the present embodiment, the second connection portion 71 is provided at one end portion of the second terminal 32, and the second wire connection portion 72 is provided at the other end portion of the second terminal 32. The connector housing 35 holds the second terminal 32 in a state where the second connection portion 71 is exposed to the outside of the connector housing 35 by burying the second wire connection portion 72 and the second coupling portion 73 inside. That is, the second terminal 32 is insert-molded into the connector housing 35. The second terminal 32 is arranged in the X direction with the first terminal 31. In addition, the second terminal 32 is arranged on the side of the wire holding portions 44 and 45 closer to the first connection portion 61 in the X direction.

[0092] The second connection portion 71 is formed in the same plate shape as the first connection portion 61. Similar to the first connection portion 61, the second connection portion 71 protrudes from the top surface of the support portion 52 of the terminal holding portion 42 to the outside of the connector housing 35 in the Y direction. The protruding direction of the second connection portion 71 from the connector housing 35 is the same as that of the first connection portion 61. In the present embodiment, the protruding direction of the second connection portion 71 is the positive Y direction. Incidentally, in the second terminal 32, the portion that protrudes from the connector housing 35 to the outside of the connector housing 35 for electrical connection to the opposing terminal 202 is the second connection portion 71. The second connection portion 71 is held by the terminal holding portion 42 in such a manner that the plate thickness direction is along the Z direction. A second connection hole 74 that penetrates the second connection portion 71 in the plate thickness direction is formed at the top end portion of the second connection portion 71 that protrudes from the top surface of the support portion 52.

[0093] In the connector 30, the position of the second connection portion 71 in the Z direction is the same as the position of the first connection portion 61 in the Z direction. And, the first connection portion 61 and the second connection portion 71 are arranged in the X direction. The first connection portion 61 is arranged at a position farther from the first lead-out position P1 than the second connection portion 71 in the X direction.

[0094] The second connecting portion 73, similar to the second connection portion 71, is formed in a flat plate shape with the plate thickness direction along the Z direction. The second connecting portion 73 has a stepped portion 75 for aligning the Z-direction position of the second connection portion 71 with the Z-direction position of the first connection portion 61. The stepped portion 75 is provided at the end portion of the second connecting portion 73 on the side of the second connection portion 71. By having the stepped portion 75 in the second connecting portion 73, the portion of the second connecting portion 73 closer to the second connection portion 71 than the stepped portion 75 is located slightly above the portion of the second connecting portion 73 closer to the second wire connection portion 72 than the stepped portion 75. In addition, in the second connecting portion 73, the difference in the Z-direction position between the two side portions of the stepped portion 75 is a value within the plate thickness range of the second terminal 32. In this specification, regarding the terminal, it is assumed that it is considered to be formed in a flat plate shape even in the case of having some steps such as the stepped portion 75.

[0095] The second terminal 32 has a direction-changing portion 76 that changes the extending direction of the second terminal 32 between the second connection portion 71 and the second wire connection portion 72. That is, the direction-changing portion 76 is provided in the second connecting portion 73. Different from the bending portion 65, the direction-changing portion 76 is a direction-changing portion that does not change the plate thickness direction on both sides of the direction-changing portion 76 but changes the extending direction of the second terminal 32. And the direction-changing portion 76 is a portion that changes the extending direction of the second terminal 32 in such a way that the portion of the second terminal 32 closer to the second wire connection portion 72 than the direction-changing portion 76 extends in a direction intersecting the protruding direction of the second connection portion 71 from the terminal holding portion 42. Therefore, in this embodiment, the portion of the second terminal 32 from the direction-changing portion 76 to the end portion on the second connection portion 71 side extends along the positive Y direction, and the plate thickness direction is along the Z direction. Further, the portion of the second terminal 32 from the direction-changing portion 76 to the end portion on the second wire connection portion 72 side extends along the X direction perpendicular to the positive Y direction, and the plate thickness direction is along the Z direction. And, when viewed from the Z direction, the portion of the second terminal 32 from the direction-changing portion 76 to the end portion on the second wire connection portion 72 side forms a perpendicular with the portion of the second terminal 32 from the end portion on the second connection portion 71 side to the direction-changing portion 76. In addition, the direction-changing portion 76 is not formed by plastic deformation such as bending processing. For example, it is formed when a metal plate is blanked into a predetermined shape by stamping processing to form the second terminal 32.

[0096] The direction-changing portion 76 is buried inside the connector housing 35. And the portion of the second terminal 32 from the direction-changing portion 76 to the end portion on the second wire connection portion 72 side is also buried inside the connector housing 35.

[0097] The second wire connection portion 72 has a pair of cylindrical pieces 77. In addition, the second terminal 32 is formed in a flat plate shape with the plate thickness direction along the Z direction as a whole except for the cylindrical pieces 77. The second wire 34 connected to the second wire connection portion 72 has a core wire 81 and an insulating coating portion 82 similar to those of the first wire 33. And the core wire 81 of the second wire 34 is made of a metal different from the material type of the second terminal 32, and is made of aluminum or an aluminum alloy.

[0098] At the end portion of the second wire 34 connected to the second wire connection portion 72, the insulating coating portion 82 is removed to expose the core wire 81. The portion of the exposed core wire 81 in this end portion of the second wire 34 is wrapped by the pair of cylindrical pieces 77 and tightened together with the cylindrical pieces 77, thereby being crimped to the second wire connection portion 72. Thus, the core wire 81 of the second wire 34 is electrically connected to the second wire connection portion 72. That is, the second wire 34 is electrically connected to the second wire connection portion 72. In addition, the end portion of the second wire 34 connected to the second wire connection portion 72 is disposed on the upper side, that is, the +Z direction side, with respect to the flat plate portion of the second terminal 32 except for the cylindrical pieces 77. The electrically connected portion of the second terminal 32 and the second wire 34 is buried inside the connector housing 35. That is, the connector housing 35 holds the electrically connected portion of the second terminal 32 and the second wire 34 inside.

[0099] The position of the second wire connection portion 72 in the Y direction is the same as that of the first wire connection portion 62. Further, when viewed from the X direction, the second wire connection portion 72 and the first wire connection portion 62 are arranged in the Z direction. In addition, the position of the second wire connection portion 72 in the X direction is disposed closer to the end portion in the X direction of the wire holding portions 44 and 45 in the connector housing 35 than the first wire connection portion 62. And the second wire connection portion 72 is buried across the holding portion 43 and the wire holding portion 45.

[0100] The second wire 34 is led out from the second wire connection portion 72 to the outside of the connector housing 35 through the inside of the connector housing 35. In the present embodiment, after the second wire 34 extends in the -X direction in the lower wire holding portion 45 from the second wire connection portion 72, it is led out to the outside of the connector housing 35 from the end face in the -X direction of the second wire connection portion 72. That is, the second wire 34 is led out from the main body portion 41 to the outside of the connector housing 35. Further, the second wire 34 is led out to the outside of the connector housing 35 along the X direction in the same manner as the first wire 33.

[0101] The second wire 34 is led out from the connector housing 35 to the outside, and the second lead-out position P2 is located on the top surface of the wire holding portion 45 in the opposite direction of X. That is, the position of the second lead-out position P2 in the X direction is the same as the position of the top surface of the wire holding portion 45 in the opposite direction of X. In addition, the position of the second lead-out position P2 in the Z direction is the same as the position of the second wire connection portion 72 in the Z direction. Further, the position of the second lead-out position P2 in the Y direction is substantially the same as the position of the end portion of the second wire 34 connected to the second wire connection portion 72 in the Y direction. And the second wire 34 does not bend or fold inside the connector housing 35, but linearly extends from the second wire connection portion 72 along the X direction to the second lead-out position P2.

[0102] The positions of the first lead-out position P1 and the second lead-out position P2 in the Y direction are the same. Further, the positions of the first lead-out position P1 and the second lead-out position P2 in the X direction are the same. And the first lead-out position P1 and the second lead-out position P2 are arranged along the Z direction perpendicular to the Y direction. The second lead-out position P2 is below the first lead-out position P1, that is, the first lead-out position P1 is located on the opposite side of the Z direction.

[0103] In addition, the first wire 33 and the second wire 34 are arranged in the Z direction inside the connector housing 35 and extend parallel to each other inside the connector housing 35. The first wire connection portion 62 is arranged at a position farther from the lead-out positions P1 and P2 in the X direction than the second wire connection portion 72. Therefore, the distance in the X direction between the first lead-out position P1 and the first wire connection portion 62 is longer than the distance in the X direction between the second lead-out position P2 and the second wire connection portion 72. That is, the length L1 of the portion of the first wire 33 embedded inside the connector housing 35, which is connected to the first terminal 31, the farther one from the lead-out positions P1 and P2 among the first terminal 31 and the second terminal 32, is longer than the length L2 of the portion of the second wire 34 embedded inside the connector housing 35, which is connected to the second terminal 32, the nearer one to the lead-out positions P1 and P2.

[0104] In addition, in the connector housing 35, when viewed from the Y direction, the first sealing grooves 46 and 47 are provided between the portions where the connection portions 61 and 71 protrude on the outer wall surface of the connector housing 35 and the portions where the lead-out wires 33 and 34 are located on the outer wall surface of the connector housing 35.

[0105] (Structure of the shielding case 36)

[0106] As Figure 4 and Figure 12As shown, the shielding case 36 has a case main body portion 91 and a separate portion 92 that is separately provided from the case main body portion 91 and assembled to the case main body portion 91. Both the case main body portion 91 and the separate portion 92 are made of a conductive metal material. As the materials for the case main body portion 91 and the separate portion 92, for example, aluminum, aluminum alloy, etc. can be used.

[0107] As Figure 7 , Figure 13 and Figure 14 shown, the case main body portion 91 has: a placement portion 101 that places the connector housing 35 inside; an insertion portion 102 provided at the end portion on the side opposite to the X direction in the placement portion 101; and a fixing portion 103 provided integrally with the placement portion 101.

[0108] The placement portion 101 has: a side wall 111 that forms a substantially cylindrical shape extending in the X direction; and a partition wall 112 that substantially closes the end portion on the side opposite to the X direction in the side wall 111. The partition wall 112 is formed in a plate shape with the plate thickness direction along the X direction. The insertion portion 102 is provided integrally with the end portion on the side opposite to the X direction in the side wall 111. The insertion portion 102 is formed in a cylindrical shape that extends in such a way as to extend the side wall 111 along the X direction from the end portion on the side opposite to the X direction in the side wall 111. The internal space of the side wall 111 and the internal space of the insertion portion 102 are demarcated in the X direction by the partition wall 112.

[0109] As Figure 13 and Figure 14 shown, the side wall 111 has a first opening portion 113 that communicates the inside of the placement portion 101 and the outside of the shielding case 36. The first opening portion 113 corresponds to the "exposed port". The first opening portion 113 is formed at the end portion on the positive Y direction side in the side wall 111 and faces the first wall portion 111a on the side of the box body 23. The first wall portion 111a is formed in a plate shape perpendicular to the Y direction. The first opening portion 113 is formed at a position near the end portion in the X direction on the side opposite to the insertion portion 102 in the first wall portion 111a. In addition, the first opening portion 113 is formed at a position near the end portion on the side opposite to the Z direction in the first wall portion 111a in the Z direction. The first opening portion 113 is formed in a hole shape that penetrates the first wall portion 111a in the plate thickness direction of the first wall portion 111a. The first opening portion 113 opens in the Y direction. The shape of the first opening portion 113 when viewed from the Y direction, which is the opening direction of the first opening portion 113, is formed in a shape that is one circle larger than the outer shape of the flange portion 51. Further, the first opening portion 113 is formed in a flat shape that is long in the X direction when viewed from the Y direction. That is, the first opening portion 113 is formed in a shape where the X direction is the long side direction and the Z direction is the short side direction.

[0110] As Figures 13 to 15As shown, the side wall 111 has a second opening 114 that connects the inside of the configuration unit 101 and the outside of the shielding case 36. The second opening 114 is provided at the end in the X direction on the side of the side wall 111 opposite to the insertion part 102. Here, the end in the X direction on the side of the side wall 111 opposite to the insertion part 102 is defined as the first end 115a, and the end in the X direction on the side of the insertion part 102 of the side wall 111 is defined as the second end 115b. The second opening 114 opens in the X direction perpendicular to the Y direction, which is the opening direction of the first opening 113. In addition, the second opening 114 is adjacently connected to the first opening 113. In the present embodiment, one end on the positive Y direction side of the second opening 114 is adjacently connected to the end in the X direction on the side of the first opening 113 opposite to the insertion part 102. In this way, the first opening 113 communicates with the second opening 114 at the end in the positive X direction of the first opening 113. The width of the second opening 114 in the Z direction is wider than the width of the first opening 113 in the Z direction. In addition, the positions of the lower ends of the first opening 113 and the second opening in the Z direction are the same. Further, the second opening 114 is larger than the outer shape of the connector housing 35 when viewed from the X direction.

[0111] As Figure 12 and Figure 13 shown, the second opening 114 is covered by the split part 92. The split part 92 is formed in a substantially quadrilateral flat plate shape. The split part 92 is fixed to the first end 115a of the side wall 111, and thus is fixed to the housing main body 91 and integrated with it. In the present embodiment, two places at both ends in the Z direction of the split part 92 are fixed to the first end 115a of the side wall 111 by screws 116.

[0112] The split part 92 is fixed to the housing main body 91 in such a manner that the plate thickness direction of the split part 92 is along the X direction. Therefore, the split part 92 extends perpendicular to the X direction. In addition, the split part 92 extends along the Z direction when viewed from the Y direction, which is the opening direction of the first opening 113.

[0113] The split part 92 forms a part of the annular inner peripheral surface of the first opening 113. Specifically, the split part 92 is located at the end in the X direction on the side of the first opening 113 opposite to the insertion part 102. And the split part 92 forms a part of the inner peripheral surface of the first opening 113 that extends along the Z direction at the end in the X direction on the side of the first opening 113 opposite to the insertion part 102.

[0114] The split portion 92 has a notch portion 117 that enlarges the first opening portion 113. The notch portion 117 is provided at the end portion on the positive Y direction side in the split portion 92. The notch portion 117 is a portion that concavely provides the lower end side portion in the front end portion of the split portion 92 toward the rear side, that is, the negative Y direction. The notch portion 117 enlarges the first opening portion 113 toward the rear side, that is, the negative Y direction. Regarding the second opening portion 114, the notch portion 117 exposes a part of the second opening portion 114.

[0115] As Figure 7 shown, in the shielding case 36, the space surrounded by the disposed portion 101 and the split portion 92 is a storage space 120 for storing the connector housing 35. Further, the side wall 111, the partition wall 112, and the split portion 92 are walls that define the storage space 120. Further, the disposed portion 101 and the split portion 92 form a storage portion 121 having the storage space 120. The first opening portion 113 communicates the storage space 120 with the outside of the storage portion 121. Further, the connector housing 35 is disposed in the storage space 120 such that the terminal holding portion 42 protrudes from the first opening portion 113 to the outside of the shielding case 36.

[0116] As Figure 7 and Figure 15 shown, insertion recesses 131 and 132 that open on the split portion 92 side, that is, on the positive X direction side, are formed in the partition wall 112. The insertion recesses 131 and 132 are recessed from the end surface in the X direction on the split portion 92 side in the partition wall 112 toward the insertion portion 102 side, that is, toward the negative X direction. Regarding the two insertion recesses 131 and 132, their positions in the Y direction are the same, and they are arranged in the Z direction. The insertion recess 132 is provided below the insertion recess 131. The shape of each of the insertion recesses 131 and 132 as viewed in the X direction is circular. The inner diameter of the insertion recess 131 is larger than the outer diameter of the wire holding portion 44. Similarly, the inner diameter of the insertion recess 132 is larger than the outer diameter of the wire holding portion 45. Further, the inner spaces of the insertion recesses 131 and 132 are part of the storage space 120.

[0117] In a state where the storage space 120 is stored in the main body portion 41, the wire holding portion 44 is inserted into the insertion recess 131, and the wire holding portion 45 is inserted into the insertion recess 132. Moreover, the end portions of the connector housing 35 that face the partition wall 112 in the X direction, that is, the tip portions on the opposite side of the X direction of the wire holding portions 44 and 45, face the partition wall 112 in the X direction. Between the outer peripheral surface of the wire holding portion 44 and the inner peripheral surface of the insertion recess 131, the wire side seal member 48 is disposed in a state of being pressed by the outer peripheral surface of the wire holding portion 44 and the inner peripheral surface of the insertion recess 131. The wire side seal member 48 seals between the outer wall surface of the connector housing 35 and the inner wall surface of the shield case 36. Specifically, the wire side seal member 48 seals between the outer peripheral surface of the wire holding portion 44 and the inner peripheral surface of the insertion recess 131 by being in liquid-tight contact with the outer peripheral surface of the wire holding portion 44 and the inner peripheral surface of the insertion recess 131. Similarly, between the inner peripheral surface of the wire holding portion 45 and the inner peripheral surface of the insertion recess 132, the wire side seal member 49 is disposed in a state of being pressed by the outer peripheral surface of the wire holding portion 45 and the inner peripheral surface of the insertion recess 132. The wire side seal member 49 seals between the outer wall surface of the connector housing 35 and the inner wall surface of the shield case 36. Specifically, the wire side seal member 49 seals between the outer peripheral surface of the wire holding portion 45 and the inner peripheral surface of the insertion recess 132 by being in liquid-tight contact with the outer peripheral surface of the wire holding portion 45 and the inner peripheral surface of the insertion recess 132. In addition, inside the storage space 120, the wire side seal member 48 and the wire side seal member 49 are in the same position in the X direction, and the wire side seal member 48 and the wire side seal member 49 are arranged in the Z direction.

[0118] As Figure 7 and Figure 16 shown, sealing recesses 133 and 134 that open to the insertion portion 102 side are formed in the partition wall 112. The sealing recesses 133 and 134 are recessed from the end surface in the X direction on the insertion portion 102 side of the partition wall 112 toward the split portion 92 side, that is, in the positive X direction. The sealing recess 133 is provided inside the insertion recess 131 in the partition wall 112. Moreover, the position of the sealing recess 133 in the Z direction is the same as that of the insertion recess 131, and the sealing recess 133 and the insertion recess 131 are arranged in the X direction. The sealing recess 134 is provided inside the insertion recess 132 in the partition wall 112. Moreover, the position of the sealing recess 134 in the Z direction is the same as that of the insertion recess 132, and the sealing recess 134 and the insertion recess 132 are arranged in the X direction. The shapes of the sealing recesses 133 and 134 as viewed from the X direction are circular.

[0119] As Figure 7 , Figure 15 and Figure 16As shown, the partition wall 112 has wire insertion through-holes 135 and 136. The wire insertion through-hole 135 is formed at the bottom of the insertion recess 131 and seals the bottom of the recess 133, penetrating the partition wall 112 in the X direction. The wire insertion through-hole 136 is formed at the bottom of the insertion recess 132 and seals the bottom of the recess 134, penetrating the partition wall 112 in the X direction. The wire insertion through-holes 135 and 136 communicate the inside and outside of the storage space 120. In the present embodiment, the wire insertion through-holes 135 and 136 communicate the storage space 120 and the internal space of the insertion portion 102. Regarding the two wire insertion through-holes 135 and 136, their positions in the X direction are the same and they are arranged in the Z direction.

[0120] In addition, a partition wall 112 having wire insertion through-holes 135 and 136 is provided at one end of the two end portions of the storage portion 121 in the X direction, and a second opening 114 covered by the split portion 92 is provided at the other end portion. Therefore, the first opening 113 is provided at a position close to the end portion on the opposite side of the end portion of the storage portion 121 in the X direction that is close to the end portions of the wire insertion through-holes 135 and 136. That is, the first opening 113 is provided at a position closer to the end portion on the side opposite to the wire insertion through-holes 135 and 136 in the X direction of the storage portion 121 than the wire insertion through-holes 135 and 136.

[0121] Inside the storage space 120, the wire-side sealing members 48 and 49 are arranged between the first opening 113 and the wire insertion through-holes 135 and 136 when viewed from the Y direction. That is, the arrangement order of the wire-side sealing members 48 and 49, the first opening 113, and the wire insertion through-holes 135 and 136 in the X direction becomes the arrangement order in which the wire-side sealing members 48 and 49 are arranged between the first opening 113 and the wire insertion through-holes 135 and 136.

[0122] As Figure 7As shown, in a state where the main body portion 41 of the connector housing 35 is disposed in the accommodation space 120, the wire insertion hole 135 and the first lead-out position P1 are opposed to each other in the X direction, and the wire insertion hole 136 and the second lead-out position P2 are opposed to each other in the X direction. The first wire 33 led out from the tip end surface of the wire holding portion 44 in the opposite direction of the X axis is led out to the outside of the shield case 36 through the wire insertion hole 135 and the insertion portion 102. The first wire 33 led out from the connector housing 35 is inserted through the wire insertion hole 135 in the X direction. And, the first wire 33 is led out from the wire insertion hole 135 to the outside of the accommodation space 120. The first wire 33 extends in the X direction from the first lead-out position P1 to the end portion on the side opposite to the partition wall 112 in the insertion portion 102. In addition, the second wire 34 led out from the tip end surface of the wire holding portion 45 in the opposite direction of the X axis is led out to the outside of the shield case 36 through the wire insertion hole 136 and the insertion portion 102. The second wire 34 led out from the connector housing 35 is inserted through the wire insertion hole 136 in the X direction. And, the second wire 34 is led out from the wire insertion hole 136 to the outside of the accommodation space 120. The second wire 34 extends in the X direction from the second lead-out position P2 to the end portion on the side opposite to the partition wall 112 in the insertion portion 102.

[0123] In addition, in the connector 30, the wire-side seal members 48 and 49 are disposed in the X direction between the connection portions 61 and 71 and the end surfaces in the X direction of the main body portion 41 from which the wires 33 and 34 are led out. Further, the portions of the outer wall surface of the main body portion 41 from which the wires 33 and 34 are led out are located between the wire-side seal members 48 and 49 and the wire insertion holes 135 and 136. In the present embodiment, the portions of the outer wall surface of the main body portion 41 from which the wires 33 and 34 are led out are located between the wire-side seal members 48 and 49 and the wire insertion holes 135 and 136 when viewed from the Y direction. That is, the arrangement order in the X direction of the portions of the outer wall surface of the main body portion 41 from which the wires 33 and 34 are led out, the wire-side seal members 48 and 49, and the wire insertion holes 135 and 136 is an arrangement order in which the portions of the outer wall surface of the main body portion 41 from which the wires 33 and 34 are led out are disposed between the wire-side seal members 48 and 49 and the wire insertion holes 135 and 136. In addition, the portions of the outer wall surface of the main body portion 41 from which the wires 33 and 34 are led out are the portions that become the exits of the wires 33 and 34 in the main body portion 41. That is, the portions of the outer wall surface of the main body portion 41 from which the wires 33 and 34 are led out are the portions of the outer wall surface of the main body portion 41 that are open at the lead-out positions P1 and P2.

[0124] As Figure 4 and Figure 7As shown, a rubber plug 141 that seals between the first electric wire 33 and the shielding case 36 is installed on the first electric wire 33 passing through the insertion portion 102. In addition, a rubber plug 142 that seals between the second electric wire 34 and the shielding case 36 is installed on the second electric wire 34 passing through the insertion portion 102. The rubber plugs 141 and 142 are formed in a ring shape. The rubber plug 141 is externally inserted into the first electric wire 33 and inserted into the sealing recess 133. The rubber plug 141 is in liquid-tight contact with the outer peripheral surface of the first electric wire 33 and the inner peripheral surface of the sealing recess 133, thereby sealing between the outer peripheral surface of the first electric wire 33 and the inner peripheral surface of the sealing recess 133. The rubber plug 142 is externally inserted into the second electric wire 34 and inserted into the sealing recess 134. The rubber plug 142 is in liquid-tight contact with the outer peripheral surface of the second electric wire 34 and the inner peripheral surface of the sealing recess 134, thereby sealing between the outer peripheral surface of the second electric wire 34 and the inner peripheral surface of the sealing recess 134.

[0125] A rear holding body 143 is installed in the insertion portion 102. The rear holding body 143 is made of an insulating resin material. The rear holding body 143 is formed in a plate shape that covers the opening of the insertion portion 102. The rear holding body 143 is inserted into the inside of the insertion portion 102 and is adjacent to the rubber plugs 141 and 142 in the X direction. The rear holding body 143 has fixing claws 144 at both ends in the Y direction. In addition, locking holes 137 are respectively formed at both ends in the Y direction in the insertion portion 102. The rear holding body 143 is fixed to the insertion portion 102 by fitting the fixing claws 144 into the locking holes 137. In addition, the rear holding body 143 has two insertion holes 145 and 146 arranged in the Z direction. The first electric wire 33 is led out to the outside of the shielding case 36 along the X direction through the insertion hole 145, and the second electric wire 34 is led out to the outside of the shielding case 36 along the X direction through the insertion hole 146.

[0126] As Figure 13 shown, the first electric wire 33 and the second electric wire 34 led out from the shielding case 36 to the outside of the shielding case 36 are covered together by a shielding conductor 147. The shielding conductor 147 has a conductive braided wire (not shown) electrically connected to the shielding case 36 and a conductive shielding tube electrically connected to the end of the braided wire. The two electric wires 33 and 34 are arranged inside the braided wire and the shielding tube.

[0127] As Figure 12 and Figure 14 shown, the fixing portion 103 is formed integrally with the first wall portion 111a. In the present embodiment, the case main body portion 91 has two fixing portions 103. The fixing portions 103 are provided on both sides in the X direction of the first opening 113 and at two places on the Z positive direction side of the first opening 113. Each fixing portion 103 protrudes from the first wall portion 111a to the outside of the shielding case 36. Each fixing portion 103 has a fixing hole 151 penetrating the fixing portion 103 in the Z direction.

[0128] The lower surface of each fixing portion 103 is a fixing surface 152 facing the mounting portion 25 of the box body 23. The fixing surface 152 of each fixing portion 103 forms a planar shape perpendicular to the Z direction which is the penetrating direction of the fixing hole 151. In addition, regarding the fixing surface 152 of one fixing portion 103 and the fixing surface 152 of the other fixing portion 103, their positions in the Z direction are the same and they are located in the same plane. In the present embodiment, when the vehicle equipped with the connector 30 is parked on a horizontal plane, the fixing surface 152 is arranged above the first opening portion 113. In addition, in the connector 30 of the present embodiment, when the vehicle is parked on a horizontal plane, the penetrating direction of the fixing hole 151 is along the vertical direction, and the fixing surface 152 is arranged perpendicular to the vertical direction.

[0129] As Figure 4 , Figure 7 , Figure 14 and Figure 15 shown, the side wall 111 which is a part of the wall defining the storage space 120 has a first wall portion 111a, a second wall portion 111b opposed to the first wall portion 111a in the Y direction, a third wall portion 111c connecting the first wall portion 111a and the second wall portion 111b on the positive Z direction side, and a fourth wall portion 111d connecting the first wall portion 111a and the second wall portion 111b on the negative Z direction side. And the side wall 111 forms a rectangular tube shape extending in the X direction. In addition, regarding the side wall 111, the so-called "rectangular tube shape" is not limited to a strict rectangular tube shape, as long as it has a shape with four walls forming a tube shape.

[0130] The third wall portion 111c and the fourth wall portion 111d are opposed in the Z direction. The outer wall surface of the third wall portion 111c forms a planar shape perpendicular to the Z direction. The fourth wall portion 111d has a first storage wall portion 161 and a second storage wall portion 162 with different distances in the Z direction from the outer wall surface of the third wall portion 111c.

[0131] The first storage wall portion 161 extends from the end portion on the negative Z direction side of the second wall portion 111b in the positive Y direction. Further, the length of the first storage wall portion 161 in the X direction is equal to the length of the side wall 111 in the X direction. That is, the first storage wall portion 161 extends from the second opening portion 114 to the partition wall 112 in the X direction.

[0132] The second storage wall portion 162 is provided at a portion of the fourth wall portion 111d that is adjacent to the second opening portion 114 in the X direction and adjacent to the first opening portion 113 in the Y direction. Further, the second storage wall portion 162 is provided in the X direction from the second opening portion 114 to a position outside the partition wall 112. Therefore, the length of the second storage wall portion 162 in the X direction is shorter than the length of the first storage wall portion 161 in the X direction. In the present embodiment, the length of the second storage wall portion 162 in the X direction is shorter than the width of the first opening portion 113 in the X direction. Further, the length of the second storage wall portion 162 in the Y direction is about half the length of the fourth wall portion 111d in the Y direction in the present embodiment.

[0133] The distance in the Z direction between the second storage wall portion 162 and the outer wall surface of the third wall portion 111c is longer than the distance in the Z direction between the first storage wall portion 161 and the outer wall surface of the third wall portion 111c. Therefore, a step is provided between the first storage wall portion 161 and the second storage wall portion 162. At the boundary portion between the first storage wall portion 161 and the second storage wall portion 162, a step wall 163 is provided that extends in the Z direction from the periphery of the second storage wall portion 162 to the periphery of the first storage wall portion 161. The step wall 163 is provided in a manner perpendicular to the Y direction at a portion that extends parallel to the X direction at the boundary portion between the first storage wall portion 161 and the second storage wall portion 162. Further, the step wall 163 is provided in a manner perpendicular to the X direction at the end portion in the X direction on the side of the partition wall 112 in the second storage wall portion 162, that is, on the side opposite to the second opening portion 114. A dehydration hole 164 that penetrates the step wall 163 in the X direction is provided in this portion of the step wall 163 that is perpendicular to the X direction. The dehydration hole 164 communicates the storage space 120 and the outside of the shield case 36.

[0134] In addition, as Figure 8 shown, in the connector housing 35 disposed in the storage space 120, the flange portion 51 is disposed at a position that overlaps the second storage wall portion 162 in the Z direction. Further, the flange portion 51 is disposed on the front side of the dehydration hole 164. Further, in the connector 30, a gap in the Y direction is formed between the flange portion 51 and the step wall 163 at a portion in the X direction that is closer to the portion that becomes the second opening portion 114 than the dehydration hole 164. Further, the tip portion of the support portion 52 and the connection portions 61 and 71 protrude from the shield case 36 in the positive Y direction from the first opening portion 113 and are exposed to the outside of the shield case 36. The first opening portion 113 exposes the first connection portion 61 and the second connection portion 71 to the outside of the storage portion 121, that is, to the outside of the shield case 36.

[0135] As Figure 7 、 Figure 14 and Figure 15As shown, the storage portion 121 has an inclined surface 165 on the inner wall surface of the storage portion 121. The inclined surface 165 is inclined with respect to a reference plane perpendicular to the Z direction, which is the penetrating direction of the fixing hole 151. When the connector 30 is arranged such that the reference plane and the horizontal plane are parallel, the inclined surface 165 is inclined with respect to the reference plane so as to guide the liquid adhering to the inclined surface 165 to the first opening 113.

[0136] In the present embodiment, a virtual plane perpendicular to the Z direction and including the fixing surface 152 and extending in the X direction and the Y direction is used as the reference plane (for example, the XY plane). However, the reference plane may be any plane perpendicular to the penetrating direction of the fixing hole 151, and a virtual plane perpendicular to the penetrating direction of the fixing hole 151 and not including the fixing surface 152 may also be used as the reference plane. In addition, the reference plane is not limited to a virtual plane perpendicular to the Z direction, and a plane of the shielding case 36 that is perpendicular to the penetrating direction of the fixing hole 151 may also be used as the reference plane. In addition, when the connector 30 is arranged such that the reference plane and the horizontal plane are parallel, the reference plane is preferably located above the inclined surface 165. In addition, in this specification, "the reference plane and the horizontal plane are parallel" not only refers to the case where the reference plane and the horizontal plane are completely parallel, but also refers to the case where the angle formed by the reference plane and the horizontal plane is less than 0.4 degrees. In addition, the inclined surface 165 "is inclined with respect to the reference plane" means that the angle formed by the reference plane and the inclined surface 165 is 0.4 degrees or more. And preferably, the angle formed by the reference plane and the inclined surface 165 is 0.7 degrees or more, more preferably 0.8 degrees or more, and most preferably 0.9 degrees or more.

[0137] In the present embodiment, the inclined surface 165 is provided on the inner wall surface of the fourth wall portion 111d. The inner wall surface of the fourth wall portion 111d has two inclined surfaces 165. The first inclined surface 166, which is one of the inclined surfaces 165, is the inner wall surface of the first storage wall portion 161, and the second inclined surface 167, which is the other inclined surface 165, is the inner wall surface of the second storage wall portion 162.

[0138] When the connector 30 is arranged such that the reference plane and the horizontal plane are parallel, the first inclined surface 166 is inclined with respect to the reference plane including the fixing surface 152 in such a way that the liquid adhering to the first inclined surface 166 is guided to the first opening 113. In the present embodiment, the distance in the Z direction between the reference plane and the first inclined surface 166, that is, the distance in the Z direction between the fixing surface 152 and the first inclined surface 166 monotonically increases as it moves away from the wire insertion holes 135 and 136 along the X direction. Further, the distance in the Z direction between the reference plane and the first inclined surface 166 monotonically increases as it approaches the first opening 113 along the Y direction. Specifically, the distance in the Z direction between the reference plane and the first inclined surface 166 gradually increases as it moves away from the wire insertion holes 135 and 136 along the X direction. Further, the distance in the Z direction between the reference plane and the first inclined surface 166 gradually increases as it approaches the first opening 113 along the Y direction. Therefore, the first inclined surface 166 forms a planar shape.

[0139] When the connector 30 is arranged such that the reference plane and the horizontal plane are parallel, the second inclined surface 167 is inclined with respect to the reference plane including the fixing surface 152 in such a way that the liquid adhering to the second inclined surface 167 is guided to the first opening 113. In the present embodiment, the distance in the Z direction between the reference plane and the second inclined surface 167, that is, the distance in the Z direction between the fixing surface 152 and the second inclined surface 167 monotonically increases as it moves away from the wire insertion holes 135 and 136 along the X direction. Further, the distance in the Z direction between the reference plane and the second inclined surface 167 monotonically increases as it approaches the first opening 113 along the Y direction. Specifically, the distance in the Z direction between the reference plane and the second inclined surface 167 gradually increases as it moves away from the wire insertion holes 135 and 136 along the X direction. Further, the distance in the Z direction between the reference plane and the second inclined surface 167 gradually increases as it approaches the first opening 113 along the Y direction. Therefore, the second inclined surface 167 forms a planar shape.

[0140] As Figure 7 , Figure 8 and Figure 14 shown, in the connector 30, the dehydration hole 164 is provided on the inclined surface 165 side in the Z direction with respect to the wire side seal member 48, and is provided on both sides in the X direction of the wire side seal member 48 on the side opposite to the wire insertion hole 135 in the X direction. Further, the dehydration hole 164 is provided at a position closer to the wire insertion hole 135 in the X direction than the center in the X direction of the second inclined surface 167. In the present embodiment, the dehydration hole 164 is provided at a position adjacent in the X direction to the end portion on the opposite side in the X direction of the second inclined surface 167.

[0141] As Figure 8As shown, on the inner wall surfaces of the first wall portion 111a and the second wall portion 111b, there are provided restricting convex portions 168 and 169 that project inwardly toward the side wall 111. The restricting convex portions 168 and 169 form ridges that project in the Y direction and extend along the X direction. The distance in the Y direction between the restricting convex portion 168 and the restricting convex portion 169 is wider than the width of the holding portion 43 in the Y direction.

[0142] As Figure 7 , Figure 8 and Figure 13 shown, in the connector 30, the connector housing 35 is disposed in the receiving space 120 such that the plate thickness direction of the first connecting portion 61 and the second connecting portion 71 becomes the Z direction. Moreover, the width of the receiving space 120 in the Z direction is wider than the width of the main body portion 41 in the Z direction. In any cross-section of the connector 30 taken by a plane parallel to the Z direction at any position in the X direction, the width of the receiving space 120 in the Z direction is wider than the width of the main body portion 41 in the Z direction. Additionally, in any cross-section of the connector 30 taken by a plane parallel to the Z direction at any position in the Y direction, the width of the receiving space 120 in the Z direction is wider than the width of the main body portion 41 in the Z direction. Further, in the portion of the receiving space 120 where the flange portion 51 is disposed, the width in the Z direction is wider than the width of the flange portion 51 in the Z direction. Also, the width of the receiving space 120 in the X direction is wider than the width of the main body portion 41 in the X direction. Further, the width of the receiving space 120 in the Y direction is wider than the width of the main body portion 41 in the Y direction.

[0143] Viewed from the Y direction, the width of the receiving space 120 in the Z direction monotonically increases as it goes from the first end 120a, which is one end in the X direction of the receiving space 120, toward the second end 120b, which is the other end in the X direction of the receiving space 120. In the present embodiment, the first end 120a is the end in the X direction on the side of the wire insertion holes 135 and 136 in the receiving space 120, and the second end 120b is the end in the X direction on the side of the second opening portion 114 in the receiving space 120. Further, viewed from the Z direction, the width of the receiving space 120 in the Y direction monotonically increases as it goes from the first end 120a toward the second end 120b. Therefore, the cross-sectional area of the receiving space 120 taken by a plane perpendicular to the X direction monotonically increases as it goes from the first end 120a toward the second end 120b along the X direction. In addition, viewed from the Y direction, the width of the main body portion 41 in the Z direction becomes the largest at one end in the X direction of the main body portion 41 located on the side of the first end 120a of the receiving space 120.

[0144] Thus, a gap is formed between the outer wall surface of the connector housing 35 and the inner wall surface of the accommodating portion 121. Therefore, the connector housing 35 can relatively move with respect to the shielding case 36 with the wire-side seal members 48 and 49 as fulcrums. The connector housing 35 can relatively move with respect to the shielding case 36 within the range of the gap between the outer wall surface of the connector housing 35 and the inner wall surface of the accommodating portion 121 with the wire-side seal members 48 and 49 as fulcrums in such a manner that the connecting portions 61 and 71 relatively move with respect to the shielding case 36 in the Z direction and the Y direction. Further, in the present embodiment, the relative movement of the holding portion 43 in the Y direction with respect to the shielding case 36 can be within the range between the restricting convex portion 168 and the restricting convex portion 169.

[0145] (Assembly of the connector 30)

[0146] When assembling the connector 30, the connector housing 35 is inserted into the interior of the accommodating space 120 from the second opening portion 114. At this time, the connector housing 35 is inserted into the interior of the accommodating space 120 from the second opening portion 114 along the X direction which is the drawing-out direction of the electric wires 33 and 34 from the connector housing 35. Specifically, in the connector housing 35 assembled to the shielding case 36, the wire-side seal members 48 and 49 are arranged in the first seal grooves 46 and 47, and the box-side seal member 54 is arranged in the second seal groove 53. And first, the electric wires 33 and 34 are inserted through the wire insertion holes 135 and 136 along the X direction from the side of the accommodating space 120 toward the insertion portion 102 side. That is, the electric wires 33 and 34 penetrate the partition wall 112 in the X direction. Then, the connector housing 35 is inserted into the interior of the accommodating space 120 along the X direction from the end portion having the drawing-out positions P1 and P2. At this time, the terminal holding portion 42 is inserted into the first opening portion 113 along the X direction from the end portion in the X direction on the side of the second opening portion 114 in the first opening portion 113. The connector housing 35 is inserted into the interior of the shielding case 36 along the X direction until the wire holding portions 44 and 45 are arranged in the insertion recesses 131 and 132, and the end portion in the X direction on the side opposite to the drawing-out positions P1 and P2 in the main body portion 41 enters the interior of the accommodating space 120. And the split portion 92 is fixed to the case main body portion 91 by the screw 116. In addition, the rubber plugs 141 and 142 are externally inserted into the electric wires 33 and 34 drawn out from the wire insertion holes 135 and 136. Further, while inserting the electric wires 33 and 34 through the insertion holes 145 and 146, the holding body 143 is fixed to the insertion portion 102.

[0147] (Installation of the connector 30 to the box body 23)

[0148] As Figure 2 and Figure 3As shown, when the connector 30 is installed on the box body 23, while inserting the first connection part 61 and the second connection part 71 into the inside of the box body 23 from the installation hole 26, the connector 30 is arranged on the box body 23. In addition, at this time, by relatively moving the connector housing 35 relative to the shielding case 36 in the Z direction and the Y direction with the wire-side sealing members 48 and 49 as fulcrums, alignment of the first connection part 61 and the mating terminal 201, and alignment of the second connection part 71 and the mating terminal 202 are performed. The fixing part 103 is arranged on the mounting part 25 in such a manner that the upper surface of the mounting part 25 and the fixing surface 152 of the fixing hole 151 face each other and the fixing hole 151 and the fixing hole 28 overlap in the Z direction. In this state, the fixing member 171 is inserted through the fixing hole 151 and the fixing hole 28, and thus the fixing part 103 is fixed to the mounting part 25 by the fixing member 171. In addition, the fixing member 171 of the present embodiment is a bolt.

[0149] In a state where the connector 30 is fixed to the box body 23, the support part 52 of the terminal holding part 42 and the box body side sealing member 54 are inserted into the installation hole 26 together. The box body side sealing member 54 seals between the outer peripheral surface of the support part 52 and the inner peripheral surface of the installation hole 26 by being in liquid-tight contact with the outer peripheral surface of the support part 52 and the inner peripheral surface of the installation hole 26. The box body side sealing member 54 suppresses liquid such as water from entering the inside of the box body 23 between the outer peripheral surface of the support part 52 and the inner peripheral surface of the installation hole 26.

[0150] In addition, the first connection part 61 is electrically connected to the mating terminal 201 inside the box body 23. For example, the first connection part 61 overlaps the mating terminal 201 in the Z direction and is electrically connected to the mating terminal 201 by a bolt and a nut inserted through the first connection hole 64. Similarly, the second connection part 71 is electrically connected to the mating terminal 202 inside the box body 23. For example, the second connection part 71 overlaps the mating terminal 202 in the Z direction and is electrically connected to the mating terminal 202 by a bolt and a nut inserted through the second connection hole 74.

[0151] In addition, as Figure 2 shown, the notch part 117 is recessed in the end part of the split part 92 facing the mounting part 25 in a direction away from the box body 23, that is, the negative Y direction when the connector 30 is installed on the box body 23. Therefore, in a state where the connector 30 is fixed to the box body 23, the notch part 117 is provided between the mounting part 25 and the split part 92, thereby forming a gap G1 whose width expands in the Y direction. The gap G1 exposes the storage space 120 to the outside of the shielding case 36.

[0152] As Figure 2 、 Figure 7 、 Figure 8 and Figure 14As shown, in the connector 30 as described above, the inclined surface 165 provided on the inner wall surface of the storage portion 121 is inclined with respect to the reference plane so as to guide the liquid adhering to the inclined surface 165 toward the first opening 113 when the connector 30 is arranged such that the reference plane and the horizontal plane are parallel. Therefore, when the vehicle is parked on a flat place extending in the horizontal direction, etc., in a state where the connector 30 is fixed to the horizontal plane on the vehicle side by the fixing member 171 inserted into the fixing hole 151, the liquid adhering to the inclined surface 165 of the shielding case 36 moves downward from the upper side in the vertical direction along the inclined surface 165. In the present embodiment, the liquid adhering to the inclined surface 165 of the shielding case 36 moves toward the first opening 113.

[0153] Specifically, when the connector 30 is splashed with a liquid such as water, a part of the liquid may penetrate into the inside of the shielding case 36, that is, the storage space 120, from openings such as the first opening 113. When the connector 30 is arranged such that the reference plane and the horizontal plane are parallel, the liquid adhering to the inclined surface 165 among the liquid penetrating into the storage space 120 is guided by the inclined surface 165 toward the first opening 113. Specifically, the liquid adhering to the first inclined surface 166 flows along the first inclined surface 166 in the X direction toward the second opening 114 side and in the Y direction toward the first opening 113 side by being guided by the first inclined surface 166. And, the liquid adhering to the first inclined surface 166 falls onto the second inclined surface 167. The liquid adhering to the second inclined surface 167 flows along the second inclined surface 167 in the X direction toward the second opening 114 side and in the Y direction toward the first opening 113 side by being guided by the second inclined surface 167. Then, the liquid flowing on the second inclined surface 167 is discharged to the outside of the shielding case 36 from the first opening 113. At this time, a part of the liquid is discharged in the positive X direction through the gap G1 formed by the notch portion 117. In addition, another part of the liquid is discharged to the outside of the shielding case 36 from the end portion on the positive Y direction side of the second inclined surface 167, that is, the lower end of the portion formed by the arrangement portion 101 in the inner peripheral surface of the first opening 113.

[0154] In addition, when the amount of the liquid penetrating into the inside of the shielding case 36 is larger than the amount of the liquid discharged from the first opening 113, etc., and when there is liquid accumulated on the second inclined surface 167, a part of the liquid is discharged to the outside of the shielding case 36 from the dehydration hole 164.

[0155] The operation and effects of the present embodiment will be described.

[0156] (1) The connector 30 includes: electric wires 33, 34 having core wires 81; a plurality of terminals 31, 32 having connection portions 61, 71 inserted into the mounting holes 26 and wire connection portions 62, 72 electrically connected to the core wires 81, the mounting holes 26 being provided in the box body 23 that houses the inverter 22; and a connector housing 35 that holds the terminals 31, 32. The mutually connected terminals 31, 32 and the core wires 81 are made of different kinds of metals. The connector housing 35 projects the connection portions 61, 71 to the outside and buries the electrical connection portions of the terminals 31, 32 and the core wires 81. Further, the connector housing 35 has a second seal groove 53 on the outer wall surface of the connector housing 35, and a box-side seal member 54 for sealing between the outer wall surface of the connector housing 35 and the inner peripheral surface of the mounting hole 26 is disposed in the second seal groove 53.

[0157] According to the above manner, the electrical connection portions of the first terminal 31 and the core wire 81 of the first electric wire 33, and the electrical connection portions of the second terminal 32 and the core wire 81 of the second electric wire 34 are buried in the connector housing 35. Therefore, even if water such as rainwater enters the inside of the shielding case 36 from the first opening 113, the connector housing 35 can be used to prevent the water from adhering to the connection portions of the terminals 31, 32 and the core wires 81. Therefore, the dissimilar metal corrosion of the connection portions of the terminals 31, 32 and the electric wires 33, 34 can be suppressed.

[0158] In addition, the connector housing 35 holds each of the terminals 31, 32 by burying a part of each of the terminals 31, 32. Therefore, the connector housing 35 can be miniaturized compared with a connector housing that assembles the terminals.

[0159] (2) The connector 30 includes a shielding case 36 that covers the outside of the connector housing 35. The shielding case 36 has a first opening 113 that communicates the inside and outside of the shielding case 36. The connection portions 61, 71 project from the first opening 113 to the outside of the shielding case 36. The connector housing 35 has first seal grooves 46, 47 on the outer wall surface of the connector housing 35, and wire-side seal members 48, 49 for sealing between the outer wall surface of the connector housing 35 and the inner wall surface of the shielding case 36 are disposed in the first seal grooves 46, 47. When viewed from the Y direction, the first seal grooves 46, 47 are provided between the portions of the outer wall surface of the connector housing 35 where the connection portions 61, 71 project and the portions of the outer wall surface of the connector housing 35 where the electric wires 33, 34 are led out.

[0160] According to the above method, the wire-side sealing members 48 and 49 can prevent the water that has entered the interior of the shielding case 36 from the first opening 113 from reaching the portions of the lead wires 33 and 34 on the outer wall surface of the connector housing 35. Therefore, it is possible to further prevent the water from adhering to the connection portions of the terminals 31 and 32 and the core wires 81. As a result, it is possible to further suppress the dissimilar metal corrosion at the connection portions of the terminals 31 and 32 and the wires 33 and 34.

[0161] (3) The wires 33 and 34 are led out from the connector housing 35 along the X direction that intersects the Y direction. The lead-out positions P1 and P2 where the wires 33 and 34 are respectively led out on the outer wall surface of the connector housing 35 are arranged along the Z direction that intersects the Y direction and the X direction.

[0162] According to the above method, each of the wires 33 and 34 is led out to the outside of the connector housing 35 along the X direction that intersects the Y direction, which is the protruding direction of the connection portions 61 and 71 from the connector housing 35. Therefore, compared with the case where each of the wires 33 and 34 is led out from the connector housing 35 along the Y direction, the connector housing 35 can be miniaturized in the Y direction. Further, the plurality of lead-out positions P1 and P2 on the outer wall surface of the connector housing 35 are arranged along the Z direction that intersects the Y direction and the X direction. Therefore, compared with the case where the two lead-out positions P1 and P2 are arranged along the Y direction, the connector housing 35 can be further miniaturized in the Y direction. As a result, since the connector housing 35 can be miniaturized, the connector 30 can be miniaturized.

[0163] In addition, in the present embodiment, the X direction, which is the lead-out direction of the wires 33 and 34 from the connector housing 35, is a direction perpendicular to the protruding direction of the connection portions 61 and 71 from the connector housing 35, that is, the Y direction. Further, the arrangement direction of the lead-out positions P1 and P2 is perpendicular to the protruding direction of the connection portions 61 and 71 from the connector housing 35, that is, the Y direction, and perpendicular to the X direction, which is the lead-out direction of the wires 33 and 34 from the connector housing 35. Therefore, it is more effective for miniaturizing the connector housing 35 in the Y direction and the X direction.

[0164] (4) The two connection portions 61 and 71 are arranged in the X direction. The lead-out positions P1 and P2 are located on one side in the X direction of the two connection portions 61 and 71. Among the two terminals 31 and 32, the first terminal 31 has the first connection portion 61 that is located at the position farthest from the lead-out positions P1 and P2 in the X direction. In addition, among the two terminals 31 and 32, the second terminal 32 has the second connection portion 71 that is located at the position closest to the lead-out positions P1 and P2 in the X direction. The length of the portion of the first wire 33 connected to the first wire connection portion 62 is longer than that of the portion of the second wire 34 connected to the second wire connection portion 72 that is buried in the connector housing 35.

[0165] According to the above method, compared with the case where the length of the portion of the first wire 33 embedded in the connector housing 35 is equal to or less than the length of the portion of the second wire 34 embedded in the connector housing 35, the first terminal 31 can be shortened in the X direction. Therefore, in the first terminal 31, the amount of use of the material of the terminal 31, which is more expensive than the wire 33, can be suppressed to a small amount. Therefore, the manufacturing cost of the connector 30 can be reduced.

[0166] (5) The first terminal 31, which is one of the two terminals 31 and 32, has a bent portion 65 disposed inside the connector housing 35 and bent. The portions of both sides of the bent portion 65 in the first terminal 31 that do not include the first connection portion 61 extend along the X direction intersecting the Y direction.

[0167] According to the above method, the first terminal 31 can be miniaturized in the Y direction. Therefore, it is easy to make the connector housing 35 holding the first terminal 31 more miniaturized in the Y direction.

[0168] (6) The first terminal 31 has a bent portion 65 between the first connection portion 61 and the first wire connection portion 62. The portion of the first terminal 31 from the bent portion 65 to the first wire connection portion 62 side extends along the Z direction.

[0169] According to the above method, in the first terminal 31, the first wire connection portion 62 is disposed at a position offset in the Z direction with respect to the first connection portion 61. And, compared with the case where the bent portion 65 is not provided in the first terminal 31, the first wire connection portion 62 can be made closer to the first connection portion 61 in the Y direction. Therefore, the distance in the Y direction between the first terminal 31 and the first wire connection portion 62 can be shortened, and thus it is easy to make the first terminal 31 more miniaturized in the Y direction. Therefore, it is easy to make the connector housing 35 holding the first terminal 31 further miniaturized in the first direction.

[0170] (7) The second wire 34 having the core wire 81 connected to the second wire connection portion 72 of the second terminal 32 different from the first terminal 31 among the two terminals 31 and 32 extends from the second wire connection portion 72 along the X direction to the second lead-out position P2 on the outer wall surface of the connector housing 35 where the second wire 34 is led out.

[0171] According to the above manner, the second wire 34 having the core wire 81 connected to the second wire connection portion 72 linearly extends along the X direction inside the connector housing 35. Therefore, compared with the case where the second wire 34 is complicatedly bent or folded inside the connector housing 35, the space occupied by the second wire 34 inside the connector housing 35 can be reduced. Accordingly, the connector housing 35 can be further miniaturized. In addition, when forming the connector housing 35, the second wire 34 does not have to be held in a complicated shape, so that the connector housing 35 holding the second terminal 32 can be easily formed.

[0172] In addition, in the present embodiment, the first wire 33 having the core wire 81 connected to the first wire connection portion 62 of the first terminal 31 extends from the first wire connection portion 62 along the X direction to the first lead-out position P1. That is, the first wire 33 linearly extends along the X direction inside the connector housing 35. Therefore, compared with the case where the first wire 33 is complicatedly bent or folded inside the connector housing 35, the space occupied by the first wire 33 inside the connector housing 35 can be reduced. Further, the first wire 33 and the second wire 34 are arranged in the Z direction and both extend along the X direction. Accordingly, the connector housing 35 can be miniaturized in the Z direction. In addition, when forming the connector housing 35, the first wire 33 does not have to be held in a complicated shape, so that the connector housing 35 holding the first terminal 31 can be easily formed.

[0173] (8) The extending directions of the portions of both sides of the bent portion 65 of the first terminal 31 that do not include the first connection portion 61 extend along the direction in which the lead-out positions P1 and P2 are arranged.

[0174] According to the above manner, compared with the case where the extending directions of the portions of both sides of the bent portion 65 of the first terminal 31 that do not include the first connection portion 61 are in a direction intersecting the direction in which the lead-out positions P1 and P2 are arranged, it is easier to reduce the space occupied by the first terminal 31 and the two wires 33 and 34 inside the connector housing 35 in the Y direction. Accordingly, the connector housing 35 can be further miniaturized. In addition, when the extending directions of the portions of both sides of the bent portion 65 of the first terminal 31 that do not include the first connection portion 61 are along the direction in which the lead-out positions P1 and P2 are arranged, a plurality of bent portions 65 do not have to be provided in the first terminal 31. In the present embodiment, the first terminal 31 has only one bent portion 65. Therefore, the complication of the shape of the first terminal 31 can be suppressed.

[0175] (9) The connection portions 61 and 71 are arranged in a direction perpendicular to the direction in which the lead-out positions P1 and P2 are arranged.

[0176] According to the above method, compared with the case where the arrangement direction of the connecting portions 61 and 71 and the arrangement direction of the lead-out positions P1 and P2 are not perpendicular, the connector housing 35 can be miniaturized in the arrangement direction of the connecting portions 61 and 71. In the present embodiment, the connecting portions 61 and 71 are arranged in the X direction, and the lead-out positions P1 and P2 are arranged in the Z direction. Therefore, the connector housing 35 can be miniaturized in the X direction.

[0177] (10) The terminals 31 and 32 are made of copper or a copper alloy. The core wire 81 is made of aluminum or an aluminum alloy.

[0178] According to the above method, the dissimilar metal corrosion of the connection portion between the terminals 31 and 32 made of copper or a copper alloy and the core wire 81 made of aluminum or an aluminum alloy can be suppressed. Moreover, the terminals 31 and 32 can be made into terminals with excellent conductivity. In addition, the wires 33 and 34 can be lightened. Therefore, the connector 30 can be further lightened.

[0179] The present embodiment can be implemented with the following modifications. The present embodiment and the following modification examples can be implemented in combination with each other within a range where there is no technical contradiction.

[0180] · In the above embodiment, the first terminal 31 and the second terminal 32 are made of copper or a copper alloy, and the core wire 81 is made of aluminum or an aluminum alloy. However, as long as the materials of the first terminal 31 and the core wire 81 included in the first wire 33 are different metals, they are not limited to the materials of the above embodiment. Similarly, as long as the materials of the second terminal 32 and the core wire 81 included in the second wire 34 are different metals, they are not limited to the materials of the above embodiment.

[0181] · The arrangement direction of the connecting portions 61 and 71 may not be a direction perpendicular to the arrangement direction of the lead-out positions P1 and P2. In addition, when the lead-out positions P1 and P2 are arranged in a direction intersecting the protruding direction of the connecting portions 61 and 71 from the connector housing 35, the connector housing 35 can be miniaturized in the protruding direction of the connecting portions 61 and 71 from the connector housing 35. Further, when the lead-out positions P1 and P2 are arranged in a direction intersecting the arrangement direction of the connecting portions 61 and 71, the connector housing 35 can be miniaturized in the arrangement direction of the connecting portions 61 and 71.

[0182] · The shapes of the first terminal 31 and the second terminal 32 are not limited to the shapes of the above embodiment.

[0183] In the above-described embodiment, the portion of the first terminal 31 from the bent portion 65 to the first wire connection portion 62 side extends along the Z direction that perpendicularly intersects the Y direction. However, the extending direction of the portion of the first terminal 31 from the bent portion 65 to the first wire connection portion 62 side is not limited thereto. The portion of the first terminal 31 from the bent portion 65 to the first wire connection portion 62 side only needs to extend along a direction that intersects the protruding direction of the connection portions 61 and 71 from the connector housing 35. In this case, the thickness direction of the portion of the first terminal 31 from the bent portion 65 to the first wire connection portion 62 side is along a direction that intersects the protruding direction of the connection portions 61 and 71 from the connector housing 35.

[0184] In addition, in the above-described embodiment, the extending direction of the portions on both sides of the bent portion 65 of the first terminal 31 that do not include the first connection portion 61 is along the direction in which the lead-out positions P1 and P2 are arranged. However, the extending direction of the portions on both sides of the bent portion 65 of the first terminal 31 that do not include the first connection portion 61 only needs to be a direction that intersects the protruding direction of the connection portions 61 and 71 from the connector housing 35, and may not be the direction along the lead-out positions P1 and P2.

[0185] In addition, in the above-described embodiment, the first terminal 31 has a bent portion 65 between the first connection portion 61 and the first wire connection portion 62. However, the position where the bent portion 65 is provided in the first terminal 31 is not limited thereto. For example, in the case where the first terminal 31 has a portion extending from the first wire connection portion 62 to the side opposite to the first connection portion 61, the bent portion 65 may be provided in this portion.

[0186] In addition, for example, the first terminal 31 may also have a plurality of bent portions 65. In addition, the first terminal 31 does not necessarily have to have a bent portion 65. In addition, a bent portion 65 may be provided in the second terminal 32. In addition, a direction-changing portion 76 may be provided in the first terminal 31. In addition, the second terminal 32 may not have a direction-changing portion 76.

[0187] · The length of the portion of the first wire 33 embedded inside the connector housing 35 may also be a length that is equal to or less than the length of the portion of the second wire 34 embedded inside the connector housing 35.

[0188] ·In the above-described embodiment, the portions of the electric wires 33 and 34 disposed inside the connector housing 35 linearly extend along the X direction. However, the extending direction and shape of the portions of the electric wires 33 and 34 disposed inside the connector housing 35 are not limited thereto. For example, at least one of the electric wires 33 and 34 may extend inside the connector housing 35 in a direction intersecting the X direction. Additionally, for example, at least one of the electric wires 33 and 34 may be bent or folded inside the connector housing 35. Further, the electric wires 33 and 34 do not necessarily have to be parallel inside the connector housing 35.

[0189] ·The direction in which the electric wires 33 and 34 are led out from the connector housing 35 is not limited to a direction perpendicularly intersecting the Y direction. For example, the direction in which the electric wires 33 and 34 are led out from the connector housing 35 may be, in addition to a direction perpendicularly intersecting the Y direction, a direction intersecting the protruding direction of the connecting portions 61 and 71 from the connector housing 35. Additionally, the direction in which the electric wires 33 and 34 are led out from the connector housing 35 may be a direction different from the direction in which the first connecting portion 61 and the second connecting portion 71 are arranged.

[0190] ·The lead-out positions P1 and P2 on the outer wall surface of the connector housing 35 may also be appropriately changed. For example, the lead-out positions P1 and P2 may be arranged, in addition to a direction perpendicularly intersecting the Y direction and perpendicularly intersecting the X direction, in a direction intersecting the protruding direction of the connecting portions 61 and 71 from the connector housing 35 and intersecting the direction in which the electric wires are led out from the connector housing 35.

[0191] ·In the above-described embodiment, the core wire 81 of the first electric wire 33 is pressed into the first electric wire connecting portion 62 by being wrapped by a pair of cylindrical pieces 66 and tightened together with the cylindrical pieces 66. However, the method of electrically connecting the first terminal 31 and the first electric wire 33 is not limited thereto. For example, the first terminal 31 and the first electric wire 33 may also be electrically connected by welding such as ultrasonic welding or laser welding. In this case, the first electric wire connecting portion 62 may not be provided with the cylindrical pieces 66. The same applies to the electrical connection between the second terminal 32 and the second electric wire 34.

Additionally, for example, in the case where the wire holding portion 44 and the wire holding portion 45 are formed integrally to form a single wire holding portion, the connector 30 may also be configured to include only one wire-side seal member. Furthermore, the connector 30 may not necessarily include the wire-side seal members 48 and 49.

[0194] · The directions and positions where the wires 33 and 34 extend from the shield case 36 can also be appropriately changed. For example, when the directions in which the wires 33 and 34 extend from the shield case 36 intersect the protruding directions of the connecting portions 61 and 71 from the connector housing 35, it is easier to miniaturize the connector 30 in the protruding directions of the connecting portions 61 and 71 from the connector housing 35.

Further, in the above-described embodiment, the "third direction", which is the direction intersecting the first direction and intersecting the second direction, corresponds to the Z direction that perpendicularly intersects the Y direction and the X direction. However, as long as the "third direction" is a direction intersecting the first direction and intersecting the second direction, it is not limited to the direction that perpendicularly intersects the Y direction and the X direction and can be set to any direction according to the first direction and the second direction. Further still, in the above-described embodiment, the "fourth direction", which is the direction intersecting the first direction, corresponds to the Z direction that perpendicularly intersects the Y direction. However, as long as the "fourth direction" is a direction intersecting the first direction, it is not limited to the direction that perpendicularly intersects the Y direction and can be set to any direction according to the first direction.

[0201] · In the illustrated embodiment, the Y direction, which is the protruding direction of the connecting portions 61 and 71 of the terminals 31 and 32, is sometimes referred to as the mounting direction or the dismounting direction of the connector 30 with respect to the mounting portion 25 of the device 21.

[0202] · In the illustrated embodiment, sometimes the mounting portion 25 of the device 21 or the combination of the mounting portion 25 and the opposing terminals 201 and 202 is referred to as the opposing connector corresponding to the connector 30. This opposing connector can be fixedly provided on the box body 23 of the device 21 and, for example, may also be integrated with the box body 23. Sometimes this opposing connector and the connector 30 are referred to as a connector pair.

[0203] · In the illustrated embodiment, the flange portion 51 (particularly the flange surface) of the connector housing 35 and / or the first opening portion 113 (particularly the opening edge) of the shield case can be configured to contact or face the top surface of the mounting portion 25.
