Detailed Description
[ description of embodiments of the present disclosure ]
First, embodiments of the present disclosure will be described.
The connector of the present disclosure is provided with a connector,
(1) the disclosed device is provided with: a plurality of terminals having a connecting portion to which a counterpart terminal is connected; a plurality of electric wires electrically connected to the connection portions of the plurality of terminals, respectively; a connector housing holding the terminal; and a shield shell that covers an outer side of the connector housing, the connector housing having a main body portion and a terminal holding portion protruding from the main body portion, the shield shell including a housing portion having a wall defining a housing space for housing the main body portion and a 1 st opening portion provided in the wall and communicating the housing space with an outside of the shield shell, the connection portion protruding from the terminal holding portion to the outside of the connector housing and protruding from the 1 st opening portion to the outside of the shield shell, the wall including a wall main body portion having a 2 nd opening portion that opens in a 2 nd direction intersecting with a 1 st direction that is an opening direction of the 1 st opening portion and is adjacent to the 1 st opening portion, and a split portion that covers the 2 nd opening portion, the 2 nd opening is located on one end side of the 1 st opening in the 2 nd direction as viewed from the 1 st direction, the 1 st opening has an annular inner peripheral surface, the inner peripheral surface of the 1 st opening is formed by the divided portion at one end portion in the 2 nd direction of the 1 st opening as viewed from the 1 st direction, and the plurality of connecting portions are arranged along the 2 nd direction.
According to the above aspect, in a state where the 2 nd opening is not covered by the divided body portion, the 1 st opening has one end portion in the 2 nd direction that is open in the 2 nd direction as viewed from the 1 st direction. And, the terminals are arranged along the 2 nd direction. Therefore, the body portion can be inserted into the housing space from the 2 nd opening along the 2 nd direction while the connection portion is inserted from the 2 nd opening toward the inside of the 1 st opening along the 2 nd direction from the end portion of the 1 st opening adjacent to the 2 nd opening, that is, the portion of the 1 st opening that opens in the 2 nd direction. In this way, the connection portion can be inserted into the 1 st opening along the 2 nd direction which is the arrangement direction of the connection portions, and therefore, the width of the 1 st opening in the direction perpendicular to the 2 nd direction as viewed from the 1 st direction can be reduced. Therefore, the part of the connector exposed from the 1 st opening to the outside of the shield case can be reduced. As a result, the shielding performance in the connector can be improved.
(2) Preferably, the body portion holds the terminal and the electric connection portion of the electric wire inside, the wall includes an opposing portion opposing the body portion in the 2 nd direction, the opposing portion has an electric wire insertion hole penetrating the opposing portion in the 2 nd direction and communicating inside and outside of the housing space, and the plurality of electric wires are drawn out from a portion of the body portion opposing the opposing portion in the 2 nd direction to the outside of the body portion in the 2 nd direction and are drawn out from the electric wire insertion hole to the outside of the housing space.
According to the above aspect, the direction in which the electric wire is inserted into the electric wire insertion hole and the direction in which the main body portion is inserted into the housing space are the same direction. Therefore, the main body can be inserted into the housing space from the 2 nd opening portion along the 2 nd direction while inserting the electric wire into the electric wire insertion hole from the housing space side along the 2 nd direction. Therefore, the assemblability of the connector is improved.
(3) Preferably, a width of the 2 nd opening in a 3 rd direction intersecting the 1 st direction and intersecting the 2 nd direction at right angles is larger than a width of the main body in the 3 rd direction.
According to the above aspect, when the body portion is inserted into the housing space from the 2 nd opening portion, the 3 rd-direction gap is generated between the inner peripheral surface of the 2 nd opening portion and the outer wall surface of the body portion. Therefore, the body can be easily inserted into the housing space from the 2 nd opening.
(4) Preferably, a width of the housing space in the 3 rd direction is larger than a width of the main body portion in the 3 rd direction.
According to the above aspect, the gap is formed between the inner wall surface of the wall defining the housing space and the outer wall surface of the body portion in the 3 rd direction. Therefore, the main body portion is relatively movable in the 3 rd direction with respect to the shield case. Therefore, the body portion moves in the 3 rd direction relative to the shield case integrally with the terminal in the housing space, and thereby, the dimensional tolerance in the 3 rd direction between the connection portion of the terminal and the mating terminal to which the connection portion is connected can be absorbed.
(5) Preferably, the wall includes an opposing portion opposing the divided portion in the 2 nd direction, a width in the 3 rd direction in the housing space monotonically increases from the opposing portion toward the divided portion along the 2 nd direction as viewed from the 1 st direction,
the width of the main body portion in the 3 rd direction is largest at one end portion of the main body portion in the 2 nd direction located on the opposite side.
According to the above aspect, the width in the 3 rd direction in the housing space decreases from the divided portion toward the opposing portion along the 2 nd direction. Therefore, the body portion can be more easily inserted into the housing space from the 2 nd opening along the 2 nd direction. Therefore, the assemblability of the connector is further improved.
(6) Preferably, the body portion holds an electrical connection portion between the terminal and the electric wire inside, and includes an annular sealing member that seals between an inner wall surface of the wall and an outer wall surface of the body portion, and at least one of the sealing members is disposed between the connection portion and a lead-out position of the body portion at which the electric wire is led out in the 2 nd direction.
According to the above aspect, the sealing member can prevent the liquid entering the housing space from the 1 st opening from reaching the electric wire drawn out from the main body.
(7) Preferably, the connector housing holds the terminal so that the connection portion protrudes to the outside and a part of the terminal is embedded.
According to the above aspect, the connector housing holds the terminal by burying a part of the terminal. Therefore, the connector housing can be made smaller than a connector housing having a terminal-mounting structure.

The positive X direction is a direction from the inside of the shield case 36 to the outside through the 2 nd opening 114 in the X direction. The X-direction is a direction from the outside of the shield case 36 to the inside via the 2 nd opening 114. In the present embodiment, the X direction and the Y direction intersect perpendicularly. The Z direction is a direction intersecting the Y direction and perpendicularly intersecting the X direction. As shown in fig. 13, when the 2 nd opening 114 is positioned on the left side of the 1 st opening 113 when the shield case 36 is viewed in the Y direction from the 1 st opening 113 side, 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 intersects perpendicularly with the Y direction and intersects perpendicularly with the X direction. In the figure, the positive Y direction, the positive X direction, and the positive Z direction are illustrated by arrows.
The Y direction corresponds to "1 st direction" in [ description of embodiments of the present disclosure ]. The X direction corresponds to "2 nd direction" in [ description of embodiments of the present disclosure ]. The Z direction corresponds to "direction 3" in [ description of embodiments of the present disclosure ].
As shown in fig. 1 and 2, the connector 30 can be attached to the housing 23 in any orientation depending on the posture of the attachment portion 25, and in the present embodiment, the connector 30 will be described with the insertion direction of the attachment hole 26 set to the front-rear direction. In fig. 1, the Y direction coincides with the penetrating direction of the mounting hole 26. The direction from the outer opening to the inner opening of the mounting hole 26 substantially coincides with the positive Y direction. The direction from the inner opening to the outer opening of the mounting hole 26 is substantially the same as the 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. The X direction is perpendicular to the insertion direction of the mounting hole 26, and substantially coincides with the direction along the longitudinal direction of the mounting hole 26. The right direction of the mounting hole 26 when viewed from the outer opening side of the mounting hole 26 substantially coincides with the positive X direction. In this case, the left direction substantially coincides with the X-direction. Further, the Z direction is perpendicular to the insertion direction of the mounting hole 26, and substantially coincides with the direction along the short side direction of the mounting hole 26. The upward direction substantially coincides with the positive Z direction. The lower side is substantially aligned with the Z direction. In the following, when describing the direction of the connector 30, the Y direction, the X direction, and the Z direction are used.
An insertion portion 27 extending along the periphery of the outer opening of the mounting hole 26 is provided on the distal end 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 tip end surface of the mounting portion 25 in the Y direction, and is formed in a ring shape.
The case 23 has a fixing hole 28 for fixing the connector 30 to the case 23. In the present embodiment, the case 23 has two fixing holes 28. Two fixing holes 28 are formed in the mounting portion 25. Two fixing holes 28 are recessed in the direction Z from the upper surface of the mounting portion 25. The two fixing holes 28 are provided above the mounting hole 26 and on both sides of the mounting hole 26 in the X direction when viewed from the insertion direction of the mounting hole 26. Each fixing hole 28 is a female screw hole.

(constitution of connector housing 35)
As shown in fig. 5, the connector housing 35 has a main body portion 41 and a terminal holding portion 42 protruding 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. The resin material of the connector housing 35 may be a resin material containing a filler such as glass fiber. The body portion 41 and the terminal holding portion 42 are integrally formed.
The shape of the main body portion 41 viewed from the Y direction is rectangular. The "rectangular shape" may not be a strict rectangular shape, and the outer shape of the main body 41 viewed from the Y direction may be substantially rectangular. That is, the outer shape of the main body 41 viewed from the Y direction is rectangular even if any one side has irregularities, any one side is gently curved, or the intersecting sides are not perpendicular to each other.
In the present embodiment, the main body 41 is formed in a rectangular shape 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 formed integrally with the holding portion 43. The holding portion 43 has a rectangular outer shape as viewed from the Y direction. The wire holding portions 44, 45 protrude from the X-direction end portions of the holding portion 43 in the X direction. The two wire holding portions 44 and 45 are aligned in the Z direction. Each of the wire holding portions 44 and 45 is formed in a cylindrical shape extending in the X direction. The tip surfaces of the two wire holding portions 44 and 45 in the X direction are perpendicular to the X direction, and the positions in the X direction are the same.
First seal grooves 46 and 47 are recessed in the outer peripheral surfaces of the wire holding portions 44 and 45. The 1 st seal groove 46 is formed in an annular shape extending along the circumferential direction of the wire holding portion 44 over the entire circumference of the wire holding portion 44 so as to surround the outer circumference of the wire holding portion 44. The 1 st seal groove 47 is formed in an annular shape extending along the circumferential direction of the wire holding portion 45 over the entire circumference of the wire holding portion 45 so as to surround the outer circumference of the wire holding portion 45. The 1 st seal grooves 46, 47 extend in the Z direction as viewed from the Y direction, and extend in the Y direction as viewed from the Z direction.
As shown in fig. 4 and 7, wire side seal members 48 and 49 are disposed in the 1 st seal grooves 46 and 47, respectively. The wire- side sealing members 48 and 49 are made of a resin material having elasticity and capable of being brought into liquid-tight close contact with the outer peripheral surfaces of the wire holding portions 44 and 45. The wire- side seal members 48 and 49 are formed in a ring shape. In the present embodiment, the wire side sealing members 48, 49 are rubber rings. The wire side seal member 48 is externally fitted to the wire holding portion 44 and disposed in the 1 st seal groove 46. The wire-side seal member 48 is positioned in the X direction with respect to the connector housing 35 by the inner surface of the 1 st seal groove 46. The wire side seal member 49 is externally inserted into the wire holding portion 45 and is disposed in the 1 st seal groove 47. The wire-side seal member 49 is positioned in the X direction with respect to the connector housing 35 by the inner surface of the 1 st seal groove 47. The wire- side seal members 48, 49 extend in the Z direction as viewed from the Y direction, and extend in the Y direction as viewed from the Z direction. The wire- side seal members 48 and 49 correspond to "seal members".
As shown in fig. 5 and 7, the width of the main body 41 in the Z direction is maximized at the ends of the main body 41 in the X direction on the side of the wire holding portions 44 and 45. When the Z-direction width of the main body portion 41 is measured, it is assumed that the width of the chamfered portion of the end portion of the main body portion 41 is ignored. In the present embodiment, the width D1 of the wire holding parts 44 and 45 between the tip surfaces in the X direction and the 1 st seal grooves 46 and 47 is the largest in the Z direction of the body 41. In the present embodiment, the width of the main body 41 in the Z direction has some steps or irregularities, but is substantially constant along the X direction.
The Y-direction width of the body 41 is maximized at the X-direction end of the body 41 on the side of the wire holding portions 44 and 45. When the Y-direction width of the main body portion 41 is measured, it is assumed that the width of the chamfered portion of the end portion of the main body portion 41 is ignored. In the present embodiment, the width D2 of the wire holding parts 44 and 45 between the tip surfaces in the X direction and the 1 st seal grooves 46 and 47 is the largest in the Y direction of the body 41.
As shown in fig. 5 and 8, the terminal holding portion 42 protrudes in the Y-positive direction from the front surface of the main body portion 41. In detail, the terminal holding portion 42 is provided integrally with a position near the lower end portion in the front surface of the main body portion 41, and a position near the end portion in the X direction on the opposite side to the wire holding portions 44, 45 in the front surface of the main body portion 41. The terminal holding portion 42 has a flange portion 51 projecting in the Y-positive direction from the front surface of the body portion 41, and a support portion 52 projecting further in the Y-positive direction from the flange portion 51. Flange portion 51 and support portion 52 are formed integrally.
The flange 51 is formed in a plate shape having a thickness direction in the Y direction. The flange 51 covers a portion near the lower end of the front surface of the body 41 and the end in the X direction on the opposite side of the wire holding portions 44 and 45 of the front surface of the body 41. The lower end of the flange 51 protrudes downward, i.e., in the direction Z, from the body 41. The position in the X direction of the end in the X positive direction in the flange 51 is the same as the position in the X direction of the end in the X positive direction in the main body 41. On the other hand, the end portion in the X direction in the flange portion 51 is positioned closer to the center in the X direction of the body portion 41 than the end portion in the X direction in the body portion 41. Further, the end portion of the flange portion 51 in the direction opposite to the X is formed in an arc shape when viewed from the Y direction.
Support portion 52 is formed in a substantially columnar shape protruding in the Y-positive direction from the center of flange portion 51. Support portion 52 has a shape having different lengths in two orthogonal directions, i.e., a shape having a longitudinal direction and a short direction, when viewed in the Y direction. In the present embodiment, the support portion 52 is formed in a shape in which the X direction is the longitudinal direction and the Y direction is the short direction. Support portion 52 is formed in a racetrack shape, i.e., a rounded rectangle, which is long in the X direction when viewed from the Y direction. The lower end of support portion 52 is located below the lower end of main body portion 41. Further, support portion 52 is housed between both ends of holding portion 43 in the X direction when viewed from the Y direction.
A 2 nd seal groove 53 is recessed in the outer peripheral surface of support portion 52. Second seal groove 53 is formed in an annular shape extending over the entire circumference of support portion 52 so as to surround the outer circumference of support portion 52. The 2 nd seal groove 53 extends in the Z direction as viewed from the X direction, and extends in the Y direction as viewed from the Z direction.
A casing side seal member 54 is disposed in the 2 nd seal groove 53. The case side sealing member 54 is made of a resin material having elasticity and capable of being brought into liquid-tight close contact with the outer peripheral surface of the support portion 52. Further, the case-side seal member 54 is formed annularly. In the present embodiment, the case-side seal member 54 is a rubber ring. The case side seal member 54 is externally fitted to the support portion 52 and disposed in the 2 nd seal groove 53. The case-side seal member 54 is positioned in the Y direction with respect to the connector housing 35 by the inner surface of the 2 nd seal groove 53.
(constitution of terminals 31, 32)
As shown in fig. 5 and 6, the connector housing 35 holds two terminals, i.e., the 1 st terminal 31 and the 2 nd terminal 32. In fig. 6 and 9 to 11, the connector housing 35 is shown in phantom by a two-dot chain line, and the outer shape of the connector housing 35 is schematically shown in a simplified manner. The 1 st terminal 31 and the 2 nd terminal 32 are made of a conductive metal material. As the material of the 1 st terminal 31 and the 2 nd terminal 32, for example, a metal having excellent conductivity such as copper, a copper alloy, aluminum, or an aluminum alloy can be used. In the present embodiment, the 1 st terminal 31 and the 2 nd terminal 32 are formed by pressing a plate material made of copper or a copper alloy.
As shown in fig. 6 and 9 to 11, the 1 st terminal 31 includes: a 1 st connection portion 61 electrically connected to a counterpart terminal 201 provided in the inverter 22; a 1 st wire connection part 62 electrically connected to the 1 st wire 33; and a 1 st coupling part 63 coupling the 1 st coupling part 61 and the 1 st wire coupling part 62. In the present embodiment, the 1 st connection portion 61 is provided at one end portion of the 1 st terminal 31, and the 1 st wire connection portion 62 is provided at the other end portion of the 1 st terminal 31. The 1 st wire connection portion 62 and the 1 st coupling portion 63 are embedded inside the connector housing 35, and the 1 st terminal 31 is held in a state where the 1 st connection portion 61 protrudes outside the connector housing 35. That is, the 1 st terminal 31 is insert-molded to the connector housing 35.
The 1 st connecting portion 61 is formed in a plate shape. The 1 st connecting portion 61 protrudes from the tip end surface of the support 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 projecting direction of the 1 st connecting portion 61 is the positive Y direction. Incidentally, in the 1 st terminal 31, a portion protruding from the connector housing 35 to the outside of the connector housing 35 for electrical connection with the counterpart terminal 201 is the 1 st connection portion 61. The 1 st connecting portion 61 is held by the terminal holding portion 42 so that the plate thickness direction is along the Z direction. A 1 st connection hole 64 that penetrates the 1 st connection portion 61 in the plate thickness direction is formed in the distal end portion of the 1 st connection portion 61 that protrudes from the distal end surface of the support portion 52.
The 1 st terminal 31 has a bent portion 65 formed by bending the 1 st terminal 31 between the 1 st connection portion 61 and the 1 st wire connection portion 62. That is, the bent portion 65 is provided in the 1 st connecting portion 63. The bent portion 65 is a portion formed by plastically deforming a metal plate material constituting the 1 st terminal 31 by bending or the like. The 1 st terminal 31 has the bent portion 65, and thus a portion of the 1 st terminal 31 on the 1 st wire connecting portion 62 side with respect to the bent portion 65 extends in a different direction from a portion of the 1 st terminal 31 on the 1 st connecting portion 61 side with respect to the bent portion 65. In detail, a portion from the end portion on the 1 st connecting portion 61 side to the bent portion 65 in the 1 st terminal 31 extends in the Y direction, and the plate thickness direction is in the Z direction. Further, of the both side portions of the bent portion 65 in the 1 st terminal 31, the portion excluding the 1 st connecting portion 61, that is, the portion from the bent portion 65 to the 1 st wire connecting portion 62 side end portion in the 1 st terminal 31 extends in the Z direction, and the plate thickness direction is along the Y direction. Therefore, a portion of the 1 st terminal 31 from the bent portion 65 to the 1 st wire connecting portion 62 side end portion is perpendicular to a portion of the 1 st terminal 31 from the 1 st connecting portion 61 side end portion to the bent portion 65.
The bent portion 65 is embedded in the connector housing 35. Further, the 1 st terminal 31 is also embedded in the connector housing 35 at a portion from the bent portion 65 to the 1 st wire connection portion 62 side end portion.
The 1 st electric wire connecting portion 62 has a pair of barrel pieces 66. The 1 st wire 33 connected to the 1 st wire connecting portion 62 has a core wire 81 and an insulating coating portion 82 that coats the outer periphery of the core wire 81 over the entire periphery. The core wire 81 may be a single wire made of one conductive metal wire or a stranded wire made of a plurality of conductive metal wires. As a material of the core wire 81, for example, a metal having excellent conductivity such as copper, a copper alloy, aluminum, and an aluminum alloy can be used. In the present embodiment, the core wire 81 is a core wire made of the same metal material as the material of the 1 st terminal 31, and is made of copper or a copper alloy. Further, the core wire 81 and the 1 st terminal 31 are not limited to being composed of the same metal material. For example, the core wire 81 and the 1 st terminal 31 may be formed of different metal materials. Specifically, in the case where the 1 st terminal 31 is composed of copper or a copper alloy, the core wire 81 may be composed of a metal material other than copper or a copper alloy, for example, aluminum or an aluminum alloy.
At the end portion of the 1 st wire 33 connected to the 1 st wire connection portion 62, the insulating coating 82 is removed to expose the core wire 81. The portion of the end of the 1 st electric wire 33, which exposes the core wire 81, is crimped to the 1 st electric wire connection part 62 by being wrapped by a pair of barrel pieces 66 and being crimped together with the barrel pieces 66. Thereby, the 1 st electric wire 33 is electrically connected to the 1 st electric wire connecting portion 62. The end portion of the 1 st wire 33 connected to the 1 st wire connection portion 62 is disposed on the rear side, i.e., on the Y-direction side, with respect to the flat plate-shaped portion of the 1 st terminal 31 from the bent portion 65 to the end portion on the 1 st wire connection portion 62 side. The 1 st terminal 31 and the 1 st wire 33 are electrically connected by being embedded in the connector housing 35. That is, the connector housing 35 holds the electrical connection portions of the 1 st terminal 31 and the 1 st electric wire 33 inside.
The 1 st electric wire 33 is drawn out from the 1 st electric wire connecting portion 62 to the outside of the connector housing 35 through the inside of the connector housing 35. In the present embodiment, the 1 st wire 33 extends from the 1 st wire connection portion 62 to the upper wire holding portion 44 inside the holding portion 43 in the X direction, and then penetrates the wire holding portion 44 in the X direction and is drawn out to the outside of the connector housing 35. That is, the 1 st electric wire 33 is drawn out from the main body portion 41 to the outside of the connector housing 35. Further, the 1 st electric wire 33 is drawn out to the outside of the connector housing 35 along the X direction.
The 1 st lead-out position P1 at which the 1 st wire 33 is led out from the connector housing 35 to the outside is located on the tip end surface of the wire holding portion 44 in the direction opposite to the X direction. That is, the position in the X direction of the 1 st drawing position P1 is the same as the position in the X direction of the tip surface of the wire holding portion 44 in the X direction. The position in the Z direction of the 1 st lead-out position P1 is the same as the position in the Z direction of the 1 st wire connecting portion 62. Further, the position in the Y direction of the 1 st lead-out position P1 is substantially the same as the position of the end of the 1 st wire 33 connected to the 1 st wire connection part 62. The 1 st wire 33 is not bent or bent inside the connector housing 35, but linearly extends from the 1 st wire connection portion 62 to the 1 st lead-out position P1 along the X direction.
The 2 nd terminal 32 has: a 2 nd connection portion 71 electrically connected to the counterpart terminal 202 provided in the inverter 22; a 2 nd electric wire connection part 72 electrically connected to the 2 nd electric wire 34; and a 2 nd coupling part 73 coupling the 2 nd connection part 71 and the 2 nd wire connection part 72. In the present embodiment, the 2 nd connection portion 71 is provided at one end portion of the 2 nd terminal 32, and the 2 nd wire connection portion 72 is provided at the other end portion of the 2 nd terminal 32. The connector housing 35 holds the 2 nd terminal 32 in a state where the 2 nd connection portion 71 protrudes outside the connector housing 35 by embedding the 2 nd wire connection portion 72 and the 2 nd connection portion 73 inside. That is, the 2 nd terminal 32 is insert-molded to the connector housing 35. The 2 nd terminal 32 and the 1 st terminal 31 are arranged in the X direction. The 2 nd terminal 32 is arranged closer to the wire holding portions 44 and 45 than the 1 st connecting portion 61 in the X direction.
The 2 nd connecting portion 71 is formed in a plate shape similar to the 1 st connecting portion 61. The 2 nd connecting portion 71 protrudes from the distal end surface of the support portion 52 of the terminal holding portion 42 to the outside of the connector housing 35 in the Y direction, similarly to the 1 st connecting portion 61. The 2 nd connecting portion 71 protrudes from the connector housing 35 in the same direction as the 1 st connecting portion 61. In the present embodiment, the projecting direction of the 2 nd connecting portion 71 is the positive Y direction. Incidentally, in the 2 nd terminal 32, a portion protruding from the connector housing 35 to the outside of the connector housing 35 for electrical connection with the counterpart terminal 202 is the 2 nd connecting portion 71. The 2 nd connecting portion 71 is held by the terminal holding portion 42 so that the plate thickness direction is along the Z direction. A 2 nd connection hole 74 for passing the 2 nd connection portion 71 in the plate thickness direction is formed in the distal end portion of the 2 nd connection portion 71 protruding from the distal end surface of the support portion 52.
In the connector 30, the Z-direction position of the 2 nd connecting portion 71 is the same as the Z-direction position of the 1 st connecting portion 61. The 1 st connection portion 61 and the 2 nd connection portion 71 are aligned in the X direction. The 1 st connection portion 61 is disposed farther from the 1 st lead-out position P1 than the 2 nd connection portion 71 in the X direction.
The 2 nd connecting portion 73 is formed in a flat plate shape with the plate thickness direction along the Z direction, similarly to the 2 nd connecting portion 71. The 2 nd connecting portion 73 has a stepped portion 75 for matching the Z-direction position of the 2 nd connecting portion 71 with the Z-direction position of the 1 st connecting portion 61. The step portion 75 is provided at the end of the 2 nd coupling portion 73 on the 2 nd coupling portion 71 side. Since the 2 nd coupling portion 73 has the stepped portion 75, the portion of the 2 nd coupling portion 73 on the 2 nd connection portion 71 side of the stepped portion 75 is positioned slightly above the portion of the 2 nd coupling portion 73 on the 2 nd wire connection portion 72 side of the stepped portion 75. In the 2 nd 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 2 nd terminal 32. In this specification, the terminal is assumed to be formed in a flat plate shape even when it has some steps such as the step portion 75.
The 2 nd terminal 32 includes a direction changing portion 76 that changes the extending direction of the 2 nd terminal 32 between the 2 nd connection portion 71 and the 2 nd wire connection portion 72. That is, the direction changing unit 76 is provided in the 2 nd coupling unit 73. The direction converting portion 76 is a direction converting portion that changes the extending direction of the 2 nd terminal 32 without changing the plate thickness direction on both sides of the direction converting portion 76, unlike the bent portion 65. The direction changing unit 76 is a portion of the 2 nd terminal 32 in which the extending direction of the 2 nd terminal 32 is changed so that, for example, a portion of the 2 nd terminal 32 closer to the 2 nd wire connecting unit 72 than the direction changing unit 76 extends in a direction intersecting the direction in which the 2 nd connecting unit 71 projects from the terminal holding unit 42. Therefore, in the present embodiment, the 2 nd terminal 32 extends in the Y-positive direction from the direction changing portion 76 to the end portion on the 2 nd connecting portion 71 side, and the plate thickness direction is along the Z-direction. Further, a portion from the direction changing portion 76 to the 2 nd wire connecting portion 72 side end portion of the 2 nd terminal 32 extends in the X direction perpendicularly intersecting the Y positive direction, and the plate thickness direction is along the Z direction. Further, the portion of the 2 nd terminal 32 from the direction changing portion 76 to the end portion on the 2 nd wire connecting portion 72 side is perpendicular to the portion of the 2 nd terminal 32 from the end portion on the 2 nd connecting portion 71 side to the direction changing portion 76 as viewed from the Z direction. The direction changing portion 76 is not formed by plastic deformation such as bending, but is formed by punching a metal plate into a predetermined shape by press working, for example, in order to form the 2 nd terminal 32.
The direction changing portion 76 is embedded in the connector housing 35. Further, the 2 nd terminal 32 is also embedded in the connector housing 35 at a portion from the direction changing portion 76 to the end portion on the 2 nd wire connecting portion 72 side.
The 2 nd electric wire connecting portion 72 has a pair of barrel pieces 77. Further, the 2 nd terminal 32 is formed in a flat plate shape whose plate thickness direction is along the Z direction as a whole except for the barrel piece 77. The 2 nd wire 34 connected to the 2 nd wire connection portion 72 has the same core wire 81 and insulating coating 82 as the 1 st wire 33. In the present embodiment, the core wire 81 of the 2 nd wire 34 is made of the same metal material as the material of the 2 nd terminal 32, and is made of copper or a copper alloy. Further, the core wire 81 of the 2 nd wire 34 and the 2 nd terminal 32 are not limited to being composed of the same metal material. For example, the core wire 81 of the 2 nd wire 34 and the 2 nd terminal 32 may be formed of different metal materials. Specifically, in the case where the 2 nd terminal 32 is composed of copper or a copper alloy, the core wire 81 of the 2 nd wire 34 may also be composed of a metal material other than copper or a copper alloy, for example, aluminum or an aluminum alloy.
At the end portion of the 2 nd wire 34 connected to the 2 nd wire connection portion 72, the insulating coating 82 is removed to expose the core wire 81. The portion of the end portion of the 2 nd electric wire 34, from which the core wire 81 is exposed, is crimped to the 2 nd electric wire connecting portion 72 by being wrapped by the pair of barrel pieces 77 and being caulked together with the barrel pieces 77. Thereby, the 2 nd electric wire 34 is electrically connected to the 2 nd electric wire connecting portion 72. Further, the end portion of the 2 nd wire 34 connected to the 2 nd wire connection portion 72 is disposed on the upper side, i.e., on the positive Z direction side with respect to the flat plate-like portion of the 2 nd terminal 32 excluding the barrel piece 77. The 2 nd terminal 32 and the 2 nd wire 34 are electrically connected by being buried in the connector housing 35. That is, the connector housing 35 holds the electrical connection portions of the 2 nd terminal 32 and the 2 nd electric wire 34 inside.
The position of the 2 nd wire connection part 72 in the Y direction is the same as that of the 1 st wire connection part 62. Further, the 2 nd wire connection part 72 and the 1 st wire connection part 62 are aligned in the Z direction as viewed from the X direction. The position of the 2 nd wire connection portion 72 in the X direction is arranged closer to the end of the 1 st wire connection portion 62 in the X direction on the wire holding portions 44 and 45 side in the connector housing 35. The 2 nd wire connecting portion 72 is embedded across the holding portion 43 and the wire holding portion 45.
The 2 nd electric wire 34 is drawn out from the 2 nd electric wire connecting portion 72 to the outside of the connector housing 35 through the inside of the connector housing 35. In the present embodiment, the 2 nd electric wire 34 extends in the X direction from the wire holding portion 45 on the lower side of the 2 nd electric wire connecting portion 72, and then is drawn out to the outside of the connector housing 35 from the tip end surface of the 2 nd electric wire connecting portion 72 in the X direction. That is, the 2 nd electric wire 34 is drawn out from the main body portion 41 to the outside of the connector housing 35. Further, the 2 nd electric wire 34 is drawn out to the outside of the connector housing 35 along the X direction, similarly to the 1 st electric wire 33.
The 2 nd lead-out position P2 at which the 2 nd wire 34 is led out from the connector housing 35 to the outside is located on the distal end surface of the wire holding portion 45 in the direction opposite to the X direction. That is, the position in the X direction of the 2 nd drawing position P2 is the same as the position in the X direction of the tip end surface of the wire holding portion 45 in the X direction. The position in the Z direction of the 2 nd lead-out position P2 is the same as the position in the Z direction of the 2 nd wire connection portion 72. Further, the position in the Y direction of the 2 nd lead-out position P2 is substantially the same as the position in the Y direction of the end of the 2 nd wire 34 connected to the 2 nd wire connecting part 72. The 2 nd wire 34 is linearly extended from the 2 nd wire connection portion 72 to the 2 nd drawing position P2 in the X direction without being bent or bent inside the connector housing 35.
The 1 st lead-out position P1 and the 2 nd lead-out position P2 are at the same position in the Y direction. Further, the 1 st lead-out position P1 and the 2 nd lead-out position P2 are the same in position in the X direction. The 1 st lead-out position P1 and the 2 nd lead-out position P2 are aligned along the Z direction perpendicular to the Y direction. The 2 nd drawing position P2 is located on the Z-direction side with respect to the 1 st drawing position P1, i.e., the 1 st drawing position P1.
In addition, the 1 st electric wire 33 and the 2 nd electric wire 34 are aligned in the Z direction inside the connector housing 35, and extend in parallel inside the connector housing 35. Since the 1 st wire connection unit 62 is disposed at a position farther from the lead-out positions P1 and P2 in the X direction than the 2 nd wire connection unit 72, the distance in the X direction between the 1 st lead-out position P1 and the 1 st wire connection unit 62 is longer than the distance in the X direction between the 2 nd lead-out position P2 and the 2 nd wire connection unit 72. That is, the length L1 of the portion embedded inside the connector housing 35 of the 1 st wire 33 connected to the 1 st terminal 31 which is farther from the lead-out positions P1 and P2 out of the 1 st terminal 31 and the 2 nd terminal 32 is longer than the length L2 of the portion embedded inside the connector housing 35 of the 2 nd wire 34 connected to the 2 nd terminal 32 which is closer to the lead-out positions P1 and P2.

As shown in fig. 4 and 12, the shield case 36 includes a case main body portion 91 and a separate portion 92 provided separately from the case main body portion 91 and attached to the case main body portion 91. The case main body 91 and the separate body 92 are made of a conductive metal material. As the material of the case main body 91 and the separate body 92, for example, aluminum alloy, or the like can be used.
As shown in fig. 7, 13, and 14, the case main body portion 91 includes: an arrangement portion 101 in which the connector housing 35 is arranged; an insertion portion 102 provided at an end portion of the arrangement portion 101 on the opposite X direction side; and a fixing portion 103 provided integrally with the arrangement portion 101.
The arrangement portion 101 has: a side wall 111 formed in a substantially cylindrical shape extending in the X direction; and a partition wall 112 that substantially closes an end portion of the side wall 111 on the X-direction side. The partition wall 112 is formed in a plate shape having a plate thickness direction along the X direction. The insertion portion 102 is provided integrally with an end portion of the side wall 111 on the X-direction side. The insertion portion 102 is formed in a cylindrical shape extending from an end portion of the side wall 111 on the side opposite to the X direction so as to extend the side wall 111 in the X direction. The internal space of the side wall 111 and the internal space of the insertion portion 102 are defined by the partition wall 112 in the X direction. The partition wall 112 corresponds to an "opposing portion".
As shown in fig. 13 and 14, the side wall 111 has a 1 st opening 113 that communicates the inside of the placement portion 101 and the outside of the shield case 36. The 1 st opening 113 is formed in the 1 st wall 111a facing the casing 23 side at the end of the side wall 111 on the Y positive direction side. The 1 st wall 111a is formed in a plate shape perpendicular to the Y direction. The 1 st opening 113 is formed in the 1 st wall portion 111a at a position close to the end in the X direction on the opposite side of the insertion portion 102. The 1 st opening 113 is formed in the Z direction at a position closer to the end of the 1 st wall 111a on the Z direction side. The 1 st opening 113 is formed in a hole shape penetrating the 1 st wall 111a in the thickness direction of the 1 st wall 111 a. The 1 st opening 113 opens in the Y direction. The shape of the 1 st opening 113 viewed from the Y direction, which is the opening direction of the 1 st opening 113, is formed to be one step larger than the outer shape of the flange 51. Further, the 1 st opening 113 is formed in a flat shape long in the X direction when viewed from the Y direction. That is, the 1 st opening 113 is formed in a shape in which the X direction is the longitudinal direction and the Z direction is the short direction.
As shown in fig. 13 to 15, the side wall 111 has a No. 2 opening 114 that communicates the inside of the arrangement portion 101 and the outside of the shield case 36. The 2 nd opening 114 is provided at an end portion in the X direction on the side opposite to the insertion portion 102, that is, on the side opposite to the partition wall 112, of the side wall 111. The 2 nd opening 114 is located on one end side of the 1 st opening 113 in the X direction, in the present embodiment, on the X positive direction side of the 1 st opening 113, as viewed from the X direction.
Here, an end portion of the side wall 111 in the X direction opposite to the insertion portion 102 is referred to as a 1 st end portion 115a, and an end portion of the side wall 111 in the X direction on the insertion portion 102 side is referred to as a 2 nd end portion 115 b. The 2 nd opening 114 opens in the X direction perpendicular to the Y direction, which is the opening direction of the 1 st opening 113. The 2 nd opening 114 is adjacent to the 1 st opening 113. In the present embodiment, the 2 nd opening 114 is connected to the 1 st opening 113 adjacent to the end of the 2 nd opening 114 in the Y positive direction side and the end of the 1 st opening 113 in the X direction opposite to the insertion portion 102. Thus, the 1 st opening 113 communicates with the 2 nd opening 114 at the end of the 1 st opening 113 on the X positive direction side. The width of the 2 nd opening 114 in the Z direction is wider than the width of the 1 st opening 113 in the Z direction. The lower end of the 1 st opening 113 and the lower end of the 2 nd opening are located at the same position in the Z direction. Further, the 2 nd opening 114 is larger than the outer shape of the connector housing 35 as viewed from the X direction.
As shown in fig. 12 and 13, the 2 nd opening 114 is covered with the divided body 92. The divided portion 92 is formed in a substantially quadrangular flat plate shape. The split portion 92 is fixed to and integrated with the case main body portion 91 by being fixed to the 1 st end portion 115a of the side wall 111. In the present embodiment, two of the both ends of the divided portion 92 in the Z direction are fixed to the 1 st end 115a of the side wall 111 by screws 116.
The divided portion 92 is fixed to the case main body portion 91 so that the plate thickness direction of the divided portion 92 is along the X direction. Therefore, the divided portion 92 extends perpendicularly to the X direction. The divided portion 92 extends in the Z direction when viewed from the Y direction, which is the opening direction of the 1 st opening 113.
The 1 st opening 113 has an annular inner peripheral surface. The partial portion 92 forms a part of the annular inner peripheral surface of the 1 st opening 113. Specifically, the divided portion 92 is located at the end in the X direction on the opposite side of the insertion portion 102 in the 1 st opening 113. The divided portion 92 is formed in the inner peripheral surface of the 1 st opening 113, and extends in the Z direction at the end in the X direction on the opposite side of the insertion portion 102 in the 1 st opening 113. Therefore, the 1 st opening 113 is provided in the side wall 111 and the divided portion 92.
The split portion 92 has a notch 117 for enlarging the 1 st opening 113. Notch 117 is provided at the end of split portion 92 on the Y positive direction side. The notch 117 is a portion in which a lower end side portion of the front end portion of the split portion 92 is recessed rearward, i.e., in the Y direction. The notch 117 enlarges the 1 st opening 113 toward the rear side, i.e., in the Y direction. In the 2 nd opening 114, the notch 117 exposes a part of the 2 nd opening 114.
As shown in fig. 7, in the shield case 36, a space surrounded by the arrangement portion 101 and the dividing portion 92 is a housing space 120 in which the connector housing 35 is housed. The side wall 111, the partition wall 112, and the divided portion 92 correspond to "walls" defining the housing space 120. The arrangement portion 101 including the side wall 111 and the partition wall 112 corresponds to a "wall body portion". Further, the arrangement portion 101 and the split portion 92 form a housing portion 121 having a housing space 120. The 1 st opening 113 communicates the housing space 120 with the outside of the shield case 36. The connector housing 35 is disposed in the housing space 120 such that the terminal holding portion 42 protrudes from the 1 st opening 113 to the outside of the shield shell 36. Further, the connection portions 61, 71 protrude from the 1 st opening 113 to the outside of the shield case 36. The opening direction of the 1 st opening 113 is the protruding direction of the connection portions 61 and 71 from the shield case 36.
As shown in fig. 7 and 15, the partition wall 112 has insertion recesses 131 and 132 that open toward the split portion 92, i.e., in the X-direction. The insertion recesses 131 and 132 are recessed from the end surface of the partition wall 112 in the X direction on the side of the dividing portion 92 toward the insertion portion 102, i.e., in the X direction. The two insertion recesses 131 and 132 are arranged at the same position in the Y direction and in the Z direction. The insertion recess 132 is provided below the insertion recess 131. The insertion recesses 131 and 132 are formed in a circular shape when viewed from the X direction. The inner diameter of the insertion recess 131 is larger than the outer diameter of the wire holding portion 44. Also, the inner diameter of the insertion recess 132 is larger than the outer diameter of the wire holding portion 45. The inner space of the insertion recesses 131 and 132 is a part of the housing space 120.
In a state where the housing space 120 is housed 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. The end of the connector housing 35 facing the partition wall 112 in the X direction, that is, the distal end of the wire holding portions 44 and 45 on the side opposite to the X direction, faces 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 sealing 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 sealing member 48 seals between the outer wall surface of the connector housing 35 and the inner wall surface of the shield shell 36. Specifically, the electric wire side sealing member 48 seals between the outer peripheral surface of the electric 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 electric wire holding portion 44 and the inner peripheral surface of the insertion recess 131. Similarly, the wire-side sealing member 49 is disposed between the inner peripheral surface of the wire holding portion 45 and the inner peripheral surface of the insertion recess 132 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 sealing member 49 seals between the outer wall surface of the connector housing 35 and the inner wall surface of the shield shell 36. Specifically, the wire-side sealing member 49 seals the space 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. Further, inside the housing space 120, the positions of the wire-side sealing member 48 and the wire-side sealing member 49 in the X direction are the same, and the wire-side sealing member 48 and the wire-side sealing member 49 are aligned in the Z direction.
As shown in fig. 7 and 16, the partition wall 112 is formed with seal recesses 133 and 134 opening on the insertion portion 102 side.

In the present embodiment, the wire insertion holes 135 and 136 communicate the housing space 120 with the internal space of the insertion portion 102. The two wire insertion holes 135 and 136 are arranged in the same position in the X direction and in the Z direction.
Further, a partition wall 112 having wire insertion holes 135, 136 is provided at one end of both ends of the housing portion 121 in the X direction, and a 2 nd opening 114 covered with the divided portion 92 is provided at the other end. Therefore, the 1 st opening 113 is provided at a position close to the end opposite to the end close to the wire insertion holes 135 and 136 among the two ends of the housing portion 121 in the X direction. That is, the 1 st opening 113 is provided closer to the ends of the housing 121 in the X direction on the opposite side of the wire insertion holes 135 and 136 than the wire insertion holes 135 and 136.
The wire- side sealing members 48 and 49 are disposed between the 1 st opening 113 and the wire insertion holes 135 and 136 in the housing space 120 as viewed from the Y direction. That is, the arrangement order of the wire- side sealing members 48, 49, the 1 st opening 113, and the wire insertion holes 135, 136 in the X direction is the arrangement order in which the wire- side sealing members 48, 49 are disposed between the 1 st opening 113 and the wire insertion holes 135, 136.
As shown in fig. 7, in a state where the main body portion 41 of the connector housing 35 is disposed in the housing space 120, the wire insertion hole 135 faces the 1 st drawn position P1 in the X direction, and the wire insertion hole 136 faces the 2 nd drawn position P2 in the X direction. That is, the wires 33 and 34 are drawn out from the portion of the main body 41 facing the partition wall 112 in the X direction to the outside of the main body 41 along the X direction. The 1 st wire 33 drawn out in the X direction from the distal end surface of the wire holding portion 44 is drawn out to the outside of the shield shell 36 through the wire insertion hole 135 and the insertion portion 102. The 1 st wire 33 drawn out from the connector housing 35 is inserted through the wire insertion hole 135 along the X direction. The 1 st wire 33 is drawn out of the housing space 120 through the wire insertion hole 135.

The portion of the outer wall surface of the body 41 from which the wires 33, 34 are drawn out is a portion of the body 41 which serves as an outlet for the wires 33, 34. That is, the portions of the outer wall surface of the body 41 from which the wires 33, 34 are drawn are portions of the outer wall surface of the body 41 that are open at the drawing positions P1, P2.
As shown in fig. 4 and 7, a rubber plug 141 for sealing between the 1 st electric wire 33 and the shield case 36 is attached to the 1 st electric wire 33 inserted through the insertion portion 102. Further, a rubber plug 142 for sealing between the 2 nd electric wire 34 and the shield case 36 is attached to the 2 nd electric wire 34 penetrating the insertion portion 102. The rubber stoppers 141, 142 are formed in a ring shape. The rubber plug 141 is externally inserted to the 1 st electric wire 33 and is inserted into the seal recess 133. The rubber plug 141 is in liquid-tight contact with the outer peripheral surface of the 1 st electric wire 33 and the inner peripheral surface of the sealing recess 133, thereby sealing the space between the outer peripheral surface of the 1 st electric wire 33 and the inner peripheral surface of the sealing recess 133. The rubber plug 142 is externally inserted to the 2 nd electric wire 34 and is inserted into the seal recess 134. The rubber plug 142 is in liquid-tight contact with the outer peripheral surface of the 2 nd electric wire 34 and the inner peripheral surface of the sealing recess 134, thereby sealing the space between the outer peripheral surface of the 2 nd electric wire 34 and the inner peripheral surface of the sealing recess 134.
The rear holding body 143 is attached to the insertion portion 102. The rear holder 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 holder 143 is inserted into the insertion portion 102 and abuts the rubber plugs 141 and 142 in the X direction. The rear holder 143 has fixing claws 144 at both ends in the Y direction. In addition, locking holes 137 are formed in both ends of the insertion portion 102 in the Y direction, respectively. The rear holder 143 is fixed to the insertion portion 102 by fitting the fixing claws 144 into the locking holes 137. The rear holder 143 has two insertion holes 145 and 146 aligned in the Z direction. The 1 st electric wire 33 is drawn out to the outside of the shield shell 36 in the X direction through the insertion hole 145, and the 2 nd electric wire 34 is drawn out to the outside of the shield shell 36 in the X direction through the insertion hole 146.
As shown in fig. 13, the 1 st electric wire 33 and the 2 nd electric wire 34 drawn out of the shield case 36 to the outside of the shield case 36 are collectively covered with a shield conductor 147. The shield conductor 147 includes a conductive braided wire, not shown, electrically connected to the shield case 36 and a conductive shield tube electrically connected to an end of the braided wire. The two wires 33 and 34 are disposed inside the braided wire and the shield tube.
As shown in fig. 12 and 14, the fixing portion 103 is formed integrally with the 1 st wall portion 111 a. In the present embodiment, the case main body portion 91 has two fixing portions 103. The fixing portions 103 are provided at two positions on both sides of the 1 st opening 113 in the X direction and on the 1 st opening 113 in the Z positive direction. Each fixing portion 103 protrudes from the 1 st wall portion 111a to the outside of the shield case 36. Each fixing portion 103 has a fixing hole 151 that penetrates the fixing portion 103 in the Z direction.
The lower surface of each fixing portion 103 is a fixing surface 152 facing the mounting portion 25 of the case 23. The fixing surface 152 of each fixing portion 103 is formed in a flat shape perpendicular to the Z direction as the penetrating direction of the fixing hole 151. The fixing surface 152 of the one fixing portion 103 and the fixing surface 152 of the other fixing portion 103 are located at the same position in the Z direction and on the same plane. In the present embodiment, the fixing surface 152 is disposed above the 1 st opening 113 when the vehicle on which the connector 30 is mounted is parked on a horizontal surface. In the connector 30 of the present embodiment, when the vehicle is parked on a horizontal surface, the insertion direction of the fixing hole 151 is along the vertical direction, and the fixing surface 152 is disposed perpendicular to the vertical direction.
As shown in fig. 4, 7, 14, and 15, the side wall 111, which is a part of the wall defining the housing space 120, includes a 1 st wall portion 111a, a 2 nd wall portion 111b facing the 1 st wall portion 111a in the Y direction, a 3 rd wall portion 111c connecting the 1 st wall portion 111a and the 2 nd wall portion 111b to each other in the Z forward direction, and a 4 th wall portion 111d connecting the 1 st wall portion 111a and the 2 nd wall portion 111b to each other in the Z reverse direction. The side wall 111 is formed in a rectangular tube shape extending in the X direction. The "rectangular cylinder" of the side wall 111 is not limited to a strict rectangular cylinder, and may be a cylinder having four walls.
The 3 rd wall 111c and the 4 th wall 111d face each other in the Z direction. The outer wall surface of the 3 rd wall portion 111c is formed in a planar shape perpendicular to the Z direction. The 4 th wall 111d has 1 st and 2 nd storage walls 161 and 162 having different distances in the Z direction from the outer wall surface of the 3 rd wall 111 c.
The 1 st accommodating wall 161 extends in the Y positive direction from the end of the 2 nd wall 111b on the Z negative direction side. Further, the length of the 1 st housing wall 161 in the X direction is equal to the length of the side wall 111 in the X direction. That is, the 1 st housing wall 161 extends from the 2 nd opening 114 to the partition wall 112 in the X direction.
The 2 nd accommodating wall portion 162 is provided in a portion of the 4 th wall portion 111d adjacent to the 2 nd opening 114 in the X direction and adjacent to the 1 st opening 113 in the Y direction. The 2 nd housing wall 162 is provided from the 2 nd opening 114 to a position outside the partition wall 112 in the X direction. Therefore, the length of the 2 nd housing wall 162 in the X direction is shorter than the length of the 1 st housing wall 161 in the X direction. In the present embodiment, the length of the 2 nd housing wall 162 in the X direction is shorter than the width of the 1 st opening 113 in the X direction. In addition, the length of the 2 nd accommodating wall portion 162 in the Y direction is, in the present embodiment, approximately half the length of the 4 th wall portion 111d in the Y direction.
The Z-direction distance between the 2 nd housing wall 162 and the outer wall surface of the 3 rd wall 111c is longer than the Z-direction distance between the 1 st housing wall 161 and the outer wall surface of the 3 rd wall 111 c. Therefore, a step is provided between the 1 st housing wall 161 and the 2 nd housing wall 162. A step wall 163 extending from the peripheral edge of the 2 nd housing wall 162 to the peripheral edge of the 1 st housing wall 161 in the Z direction is provided at the boundary between the 1 st housing wall 161 and the 2 nd housing wall 162. The step wall 163 is provided so as to be perpendicular to the Y direction at a portion extending parallel to the X direction at a boundary portion between the 1 st housing wall 161 and the 2 nd housing wall 162. The step wall 163 is provided on the partition wall 112 side of the 2 nd housing wall portion 162, that is, on the end portion in the X direction opposite to the 2 nd opening 114, so as to be perpendicular to the X direction. The dewatering hole 164 that penetrates the step wall 163 in the X direction is provided in the portion of the step wall 163 that is perpendicular to the X direction. The dehydrating hole 164 communicates the receiving space 120 with the outside of the shield case 36.
As shown in fig. 8, in the connector housing 35 disposed in the housing space 120, the flange portion 51 is disposed at a position overlapping the 2 nd housing wall portion 162 in the Z direction. The flange 51 is disposed on the front side of the dewatering 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 that becomes the 2 nd opening 114 in the X direction than the dewatering hole 164. The distal end portion of the support portion 52 and the connection portions 61 and 71 protrude from the shield case 36 in the Y-positive direction from the 1 st opening 113 and are exposed to the outside of the shield case 36. The 1 st opening 113 exposes the 1 st connection portion 61 and the 2 nd connection portion 71 to the outside of the housing 121, that is, the outside of the shield case 36.
As shown in fig. 7, 14, and 15, the housing section 121 has an inclined surface 165 on an inner wall surface of the housing section 121, and the inclined surface 165 is inclined with respect to a reference plane perpendicular to the Z direction which is a penetrating direction of the fixing hole 151. When the connector 30 is disposed so that the reference plane and the horizontal plane are parallel to each other, the inclined surface 165 is inclined with respect to the reference plane so as to guide the liquid attached to the inclined surface 165 to the 1 st opening 113.
In the present embodiment, a virtual plane perpendicular to the Z direction, including the fixed surface 152, and extending in the X direction and the Y direction is used as a reference plane (for example, XY plane). However, the reference plane may be a plane perpendicular to the insertion direction of the fixing hole 151, and a virtual plane perpendicular to the insertion direction of the fixing hole 151 and not including the fixing surface 152 may be used as the reference plane. The reference surface is not limited to a virtual plane perpendicular to the Z direction, and a plane provided in the shield case 36 and perpendicular to the insertion direction of the fixing hole 151 may be used as the reference surface. When the connector 30 is disposed so that the reference plane and the horizontal plane are parallel to each other, the reference plane is preferably located above the inclined surface 165. In the present specification, the phrase "the reference plane and the horizontal plane are parallel" means not only a case where the reference plane and the horizontal plane are completely parallel but also a case where an angle formed by the reference plane and the horizontal plane is less than 0.4 degrees. The inclined surface 165 "inclined with respect to the reference surface" means that the angle formed by the reference surface and the inclined surface 165 is 0.4 degrees or more. The angle formed by the reference plane and the inclined plane 165 is preferably 0.7 degrees or more, more preferably 0.8 degrees or more, and most preferably 0.9 degrees or more.
In the present embodiment, the inclined surface 165 is provided on the inner wall surface of the 4 th wall portion 111 d. The inner wall surface of the 4 th wall 111d has two inclined surfaces 165. The 1 st inclined surface 166 as the one inclined surface 165 is an inner wall surface of the 1 st housing wall 161, and the 2 nd inclined surface 167 as the other inclined surface 165 is an inner wall surface of the 2 nd housing wall 162.
When the connector 30 is disposed such that the reference plane and the horizontal plane are parallel to each other, the 1 st inclined surface 166 is inclined with respect to the reference plane including the fixing surface 152 so as to guide the liquid adhering to the 1 st inclined surface 166 to the 1 st opening 113. In the present embodiment, the distance in the Z direction between the reference surface and the 1 st inclined surface 166, that is, the distance in the Z direction between the fixing surface 152 and the 1 st inclined surface 166 monotonically increases as the distance from the wire insertion holes 135 and 136 along the X direction increases. Further, the distance in the Z direction between the reference surface and the 1 st inclined surface 166 monotonically increases as the opening 113 approaches along the Y direction. In detail, the distance in the Z direction between the reference surface and the 1 st inclined surface 166 gradually increases as being apart from the wire insertion holes 135, 136 along the X direction. Further, the distance in the Z direction between the reference surface and the 1 st inclined surface 166 gradually increases as approaching the 1 st opening 113 along the Y direction. Therefore, the 1 st inclined surface 166 is formed in a planar shape.
When the connector 30 is disposed so that the reference plane and the horizontal plane are parallel to each other, the 2 nd inclined surface 167 is inclined with respect to the reference plane including the fixed surface 152 so as to guide the liquid attached to the 2 nd inclined surface 167 to the 1 st opening 113. In the present embodiment, the distance in the Z direction between the reference surface and the 2 nd inclined surface 167, that is, the distance in the Z direction between the fixing surface 152 and the 2 nd inclined surface 167 monotonously increases as being away from the wire insertion holes 135, 136 along the X direction. Further, the distance in the Z direction between the reference surface and the 2 nd inclined surface 167 monotonously increases as approaching the 1 st opening 113 along the Y direction. In detail, the distance in the Z direction between the reference surface and the 2 nd inclined surface 167 gradually increases as being apart from the wire insertion holes 135, 136 along the X direction. Further, the distance in the Z direction between the reference surface and the 2 nd inclined surface 167 gradually increases as approaching the 1 st opening 113 along the Y direction. Therefore, the 2 nd inclined surface 167 is formed in a planar shape.
As shown in fig. 7, 8, and 14, in the connector 30, the dewatering holes 164 are provided on the inclined surface 165 side of the wire-side sealing member 48 in the Z direction, and are provided on the opposite side of the wire insertion hole 135 from the both sides of the wire-side sealing member 48 in the X direction. Further, the dewatering hole 164 is provided at a position closer to the wire insertion hole 135 in the X direction than the center of the 2 nd inclined surface 167 in the X direction. In the present embodiment, the dewatering holes 164 are provided at positions adjacent to the end of the 2 nd inclined surface 167 on the side opposite to the X direction in the X direction.
As shown in fig. 8, restricting convex portions 168 and 169 protruding inward of the side wall 111 are provided on the inner wall surface of the 1 st wall portion 111a and the inner wall surface of the 2 nd wall portion 111 b. The restricting convex portions 168 and 169 form protruding strips that protrude in the Y direction and extend in the X direction. The distance 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.
As shown in fig. 7, 8, and 13, in the connector 30, the connector housing 35 is disposed in the housing space 120 such that the plate thickness direction of the 1 st connecting portion 61 and the 2 nd connecting portion 71 is the Z direction. The Z-direction width of the housing space 120 is wider than the Z-direction width of the body 41. In the cross section of the connector 30 taken on a plane parallel to the Z direction at any position in the X direction, the Z-direction width of the housing space 120 is wider than the Z-direction width of the body portion 41. In addition, in the cross section of the connector 30 taken on a plane parallel to the Z direction at any position in the Y direction, the Z-direction width of the housing space 120 is larger than the Z-direction width of the body portion 41. Further, in the portion of the housing space 120 where the flange portion 51 is disposed, the width in the Z direction is wider than the width in the Z direction of the flange portion 51. The width of the housing space 120 in the X direction is wider than the width of the body 41 in the X direction. Further, the Y-direction width of the housing space 120 is wider than the Y-direction width of the body 41.
The width of the storage space 120 in the Z direction monotonically increases from the 1 st end 120a, which is one end in the X direction in the storage space 120, toward the 2 nd end 120b, which is the other end in the X direction in the storage space 120, as viewed from the Y direction. In the present embodiment, the 1 st end 120a is an end of the housing space 120 on the partition wall 112 side in the X direction, and the 2 nd end 120b is an end of the housing space 120 on the divided portion 92 side in the X direction. Further, the width of the storage space 120 in the Y direction monotonically increases from the 1 st end 120a toward the 2 nd end 120b as viewed from the Z direction. Therefore, the sectional area of the housing space 120 taken with a plane perpendicular to the X direction monotonically increases from the 1 st end 120a toward the 2 nd end 120b along the X direction. Further, the width of the main body 41 in the Z direction is largest at one end of the main body 41 in the X direction on the 1 st end 120a side of the housing space 120 as viewed from the Y direction.
Thereby, a gap is formed between the outer wall surface of the connector housing 35 and the inner wall surface of the housing section 121. Therefore, the connector housing 35 can move relative to the shield shell 36 with the wire- side sealing members 48 and 49 as fulcrums. The connector housing 35 is movable relative to the shield shell 36 within a range of a gap between an outer wall surface of the connector housing 35 and an inner wall surface of the housing portion 121 with the wire- side seal members 48, 49 as fulcrums so that the connection portions 61, 71 are movable relative to the shield shell 36 in the Z direction and the Y direction. In the present embodiment, the relative movement of the holding portion 43 with respect to the shield case 36 in the Y direction can be within a range between the restricting convex portion 168 and the restricting convex portion 169.
(Assembly of connector 30)
When the connector 30 is assembled, the connector housing 35 is inserted into the housing space 120 through the 2 nd opening 114. At this time, the connector housing 35 is inserted into the housing space 120 from the 2 nd opening 114 along the X direction which is the drawing direction of the wires 33 and 34 from the connector housing 35. Specifically, in the connector housing 35 assembled to the shield shell 36, the wire side seal members 48 and 49 are disposed in the 1 st seal groove 46 and 47, and the box side seal member 54 is disposed in the 2 nd seal groove 53. Then, first, the wires 33, 34 are inserted through the wire insertion holes 135, 136 along the X direction from the housing space 120 side toward the insertion portion 102 side. That is, the wires 33 and 34 penetrate the partition wall 112 in the X direction. Then, the connector housing 35 is inserted into the housing space 120 from the end having the lead-out positions P1, P2 along the X direction. At this time, the terminal holding portion 42 is inserted into the 1 st opening 113 along the X direction from the end portion of the 1 st opening 113 in the X direction on the 2 nd opening 114 side. The connector housing 35 is inserted into the shield case 36 along the X direction until the wire holding portions 44 and 45 are disposed in the insertion recesses 131 and 132 and the X-direction end portions of the main body portion 41 opposite to the lead-out positions P1 and P2 enter the receiving space 120. The separate body 92 is fixed to the case main body 91 by a screw 116. The rubber plugs 141 and 142 are externally inserted to the wires 33 and 34 drawn out from the wire insertion holes 135 and 136. Further, the rear holding body 143 is fixed to the insertion portion 102 while the wires 33, 34 are inserted into the insertion holes 145, 146.
(mounting of connector 30 to case 23)
As shown in fig. 2 and 3, when connector 30 is attached to case 23, connector 30 is disposed in case 23 while inserting connection 1 and connection 2 61 and connection 71 from attachment hole 26 into case 23. At this time, the connector housing 35 is relatively moved in the Z direction and the Y direction with respect to the shield shell 36 with the wire- side sealing members 48 and 49 as fulcrums, whereby the 1 st connection portion 61 and the mating terminal 201 are aligned, and the 2 nd connection portion 71 and the mating terminal 202 are aligned. The fixing portion 103 is disposed on the mounting portion 25 such that the upper surface of the mounting portion 25 faces the fixing surface 152 of the fixing hole 151 and the fixing hole 151 overlaps the fixing hole 28 in the Z direction. In this state, the fixing member 171 is inserted into the fixing hole 151 and the fixing hole 28, and the fixing portion 103 is fixed to the mounting portion 25 by the fixing member 171. The fixing member 171 of the present embodiment is a bolt.
In a state where connector 30 is fixed to case 23, support portion 52 of terminal holding portion 42 is inserted into mounting hole 26 together with case-side sealing member 54. Case side sealing member 54 seals between the outer peripheral surface of support portion 52 and the inner peripheral surface of mounting hole 26 by being in liquid-tight close contact with the outer peripheral surface of support portion 52 and the inner peripheral surface of mounting hole 26. Tank-side sealing member 54 prevents liquid such as water from entering the inside of tank 23 from between the outer peripheral surface of support portion 52 and the inner peripheral surface of mounting hole 26.
The 1 st connection portion 61 is electrically connected to the counterpart terminal 201 inside the case 23. For example, the 1 st connecting part 61 overlaps the counterpart terminal 201 in the Z direction, and is electrically connected to the counterpart terminal 201 by a bolt and a nut inserted through the 1 st connecting hole 64. Similarly, the 2 nd connector 71 is electrically connected to the mating terminal 202 in the case 23. For example, the 2 nd connecting portion 71 overlaps the counterpart terminal 202 in the Z direction, and is electrically connected to the counterpart terminal 202 by a bolt and a nut inserted through the 2 nd connecting hole 74.
As shown in fig. 2, notch 117 is recessed in the direction away from housing 23 when connector 30 is attached to housing 23, i.e., in the direction Y, at the end of divided portion 92 facing attachment portion 25. Therefore, in a state where the connector 30 is fixed to the housing 23, the gap G1 whose width is enlarged in the Y direction is formed by providing the notch 117 between the attachment portion 25 and the separate portion 92. The gap G1 exposes the housing space 120 to the outside of the shield case 36.
As shown in fig. 2, 7, 8, and 14, in the connector 30 described above, when the connector 30 is disposed such that the reference plane and the horizontal plane are parallel to each other, the inclined surface 165 provided on the inner wall surface of the housing portion 121 is inclined with respect to the reference plane so as to guide the liquid adhering to the inclined surface 165 to the 1 st opening 113. Therefore, in a case where the vehicle is parked in a flat place extending in the horizontal direction, the liquid adhering to the inclined surface 165 of the shield case 36 moves from the upper side to the lower side in the vertical direction along the inclined surface 165 in a state where the connector 30 is fixed to the horizontal surface on the vehicle side using the fixing member 171 inserted through the fixing hole 151. In the present embodiment, the liquid adhering to the inclined surface 165 of the shield case 36 moves toward the 1 st opening 113.
Specifically, when the connector 30 is splashed with a liquid such as water, a part of the liquid may enter the housing space 120, which is the inside of the shield case 36, through the opening 1, such as the opening 113. When the connector 30 is disposed so that the reference plane and the horizontal plane are parallel to each other, the liquid adhering to the inclined surface 165 among the liquids entering the housing space 120 is guided to the 1 st opening 113 by the inclined surface 165. Specifically, the liquid adhering to the 1 st inclined surface 166 flows along the 1 st inclined surface 166 toward the 2 nd opening 114 side in the X direction and toward the 1 st opening 113 side in the Y direction, as guided by the 1 st inclined surface 166. The liquid adhering to the 1 st inclined surface 166 falls on the 2 nd inclined surface 167. The liquid adhering to the 2 nd inclined surface 167 flows along the 2 nd inclined surface 167 toward the 2 nd opening 114 side in the X direction and toward the 1 st opening 113 side in the Y direction by being guided by the 2 nd inclined surface 167. Then, the liquid flowing on the 2 nd inclined surface 167 is discharged to the outside of the shield case 36 from the 1 st opening 113. At this time, a part of the liquid is discharged in the X positive direction through the gap G1 formed by the notch 117. The other part of the liquid is discharged to the outside of the shield case 36 from the end portion on the Y positive direction side of the 2 nd inclined surface 167, that is, the lower end of the portion formed by the arrangement portion 101 in the inner peripheral surface of the 1 st opening 113.
In addition, when the amount of liquid entering the inside of the shield case 36 is increased compared to the amount of liquid discharged from the 1 st opening 113, and the liquid is accumulated on the 2 nd inclined surface 167, a part of the liquid is discharged from the dewatering holes 164 to the outside of the shield case 36.
The operation and effect of the present embodiment will be described.
(1) The connector 30 includes: terminals 31, 32 having connection parts 61, 71 to which the counterpart terminals 201, 202 are connected; electric wires 33, 34 electrically connected to the connection portions 61, 71; a connector housing 35 holding the terminals 31, 32; and a shield shell 36 covering the outside of the connector housing 35. The connector housing 35 has a main body portion 41 and a terminal holding portion 42 protruding from the main body portion 41. The shield case 36 includes a housing portion 121, and the housing portion 121 includes a side wall 111, a partition wall 112, and a dividing portion 92 defining a housing space 120 for housing the body portion 41, and a 1 st opening 113 provided in the side wall 111 and the dividing portion 92 and communicating the housing space 120 with the outside of the shield case 36. The connection portions 61, 71 project from the terminal holding portion 42 to the outside of the connector housing 35, and project from the 1 st opening portion 113 to the outside of the shield shell 36. The side wall 111 has a 2 nd opening 114, and the 2 nd opening 114 is opened in the X direction intersecting the Y direction which is the opening direction of the 1 st opening 113 and is adjacent to the 1 st opening 113. The 2 nd opening 114 is covered with the separate body 92. The 2 nd opening 114 is located on one end side of the 1 st opening 113 in the X direction as viewed from the Y direction. The 1 st opening 113 has an annular inner peripheral surface. At one end in the X direction of the 1 st opening 113 viewed from the Y direction, the inner peripheral surface of the 1 st opening 113 is formed by the divided part 92. The two connection portions 61 and 71 are aligned in the X direction.
According to the above-described aspect, in a state where the 2 nd opening 114 is not covered with the divided body 92, one end portion of the 1 st opening 113 in the X direction, that is, an end portion of the 1 st opening 113 in the X positive direction is opened in the X direction as viewed from the Y direction. The terminals 31 and 32 are arranged along the X direction. Therefore, the body portion 41 can be inserted from the 2 nd opening 114 into the housing space 120 along the X direction while inserting the connection portions 61 and 71 from the end portion of the 1 st opening 113 adjacent to the 2 nd opening 114, that is, the portion of the 1 st opening 113 that opens in the X direction, toward the inside of the 1 st opening 113 along the X direction. In this way, since the connection portions 61 and 71 can be inserted into the 1 st opening 113 along the X direction which is the arrangement direction of the connection portions 61 and 71, the width of the 1 st opening 113 in the Z direction perpendicular to the X direction when viewed from the Y direction can be reduced. Therefore, the portion of the connector 30 exposed to the outside of the shield case 36 from the 1 st opening 113 can be reduced. As a result, the shielding performance in the connector 30 can be improved.
(2) The body portion 41 holds the electrical connection portions of the terminals 31, 32 and the electric wires 33, 34 inside. Among the side wall 111, the partition wall 112, and the divided portion 92 defining the housing space 120, the partition wall 112 faces the divided portion 92 in the X direction. The partition wall 112 has wire insertion holes 135 and 136 that penetrate the partition wall 112 in the X direction and communicate the inside and outside of the housing space 120. The wires 33, 34 are drawn out to the outside of the body 41 along the X direction from the portion of the body 41 opposed to the partition wall 112 in the X direction, and are drawn out to the outside of the housing space 120 from the wire insertion holes 135, 136.
According to the above-described manner, the direction in which the electric wires 33, 34 are inserted into the electric wire insertion holes 135, 136 and the direction in which the main body portion 41 is inserted into the housing space 120 are the same direction. Therefore, the main body 41 can be inserted into the housing space 120 from the 2 nd opening 114 along the X direction while inserting the wires 33 and 34 into the wire insertion holes 135 and 136 along the X direction from the housing space 120 side. Therefore, the assemblability of the connector 30 is improved.
(3) The width of the 2 nd opening 114 in the Z direction intersecting the Y direction and perpendicular to the X direction is larger than the width of the main body 41 in the Z direction.
According to the above-described aspect, when the body 41 is inserted into the housing space 120 from the 2 nd opening 114, a Z-direction gap is generated between the inner peripheral surface of the 2 nd opening 114 and the outer wall surface of the body 41. Therefore, the body 41 can be easily inserted into the housing space 120 through the 2 nd opening 114.
(4) The Z-direction width of the housing space 120 is larger than the Z-direction width of the body 41.
According to the above aspect, a gap is formed between the inner wall surface of the side wall 111 defining the housing space 120 and the outer wall surface of the body portion 41 in the Z direction. Therefore, the main body portion 41 is relatively movable in the Z direction with respect to the shield case 36. Therefore, the body 41 moves in the Z direction relative to the shield case 36 integrally with the terminals 31 and 32 in the housing space 120, and thus can absorb the dimensional tolerance in the Z direction between the connection portions 61 and 71 and the counterpart terminals 201 and 202.
(5) The width of the housing space 120 in the Z direction monotonically increases from the partition wall 112 toward the divider 92 along the X direction as viewed from the Y direction. The width of the body 41 in the Z direction is largest at one end of the body 41 on the partition wall 112 side in the X direction.
According to the above aspect, the width of the housing space 120 in the Z direction decreases from the divided portion 92 toward the partition wall 112 along the X direction. Therefore, the body 41 can be more easily inserted into the housing space 120 from the 2 nd opening 114 along the X direction. Therefore, the assemblability of the connector 30 is further improved.
(6) The body portion 41 holds the electrical connection portions of the terminals 31, 32 and the electric wires 33, 34 inside. The connector 30 includes annular wire- side sealing members 48 and 49 for sealing between the inner wall surface of the partition wall 112 and the outer wall surface of the body 41. The wire- side sealing members 48 and 49 are disposed between the connection portions 61 and 71 and the lead positions P1 and P2 of the lead wires 33 and 34 in the main body portion 41 in the X direction.
According to the above-described aspect, the liquid that enters the housing space 120 from the 1 st opening 113 can be prevented from reaching the electric wires 33 and 34 drawn out from the main body 41 by the electric wire side sealing members 48 and 49.
(7) The connector housing 35 holds the terminals 31, 32 so that the connection portions 61, 71 protrude to the outside and part of the terminals 31, 32 is embedded.
According to the above-described manner, the connector housing 35 holds the terminals 31, 32 by burying a part of the terminals 31, 32. Therefore, the connector housing 35 can be made smaller than a connector housing having a terminal-mounting structure.
This embodiment can be modified as follows. The present embodiment and the following modifications can be combined and implemented within a range not technically contradictory to the technology.
In the above embodiment, the connector housing 35 holds the terminals 31 and 32 by embedding a part of the terminals 31 and 32. However, the connector housing 35 may not embed a part of the terminals 31 and 32. In this case, the terminals 31, 32 are fixed to a pre-formed connector housing.
The arrangement of the wire- side sealing members 48 and 49 in the housing space 120 is not limited to that of the above embodiment. The wire- side sealing members 48 and 49 are disposed in the housing space 120 and can seal between the inner wall surface of the shield case 36 and the outer wall surface of the body 41. For example, the wire-side sealing member may be disposed between the 2 nd drawing position P2 and the 1 st opening 113 in the Z direction. In this case, the wire-side sealing member extends, for example, in the X direction as viewed from the Y direction, and extends in the Y direction as viewed from the X direction. Further, in this case, the wire-side sealing member extends so as to surround the outer periphery of the main body portion 41, for example, as viewed from the Z direction.
The shape of the wire- side seal members 48, 49 is not limited to that of the above embodiment. The wire- side sealing members 48 and 49 may be disposed in the housing space 120 and may have a shape capable of sealing between the inner wall surface of the shield case 36 and the outer wall surface of the body portion 41. For example, when the wire holding portion 44 and the wire holding portion 45 are integrally formed as one wire holding portion, the connector 30 may be configured to include only one wire-side sealing member. The connector 30 does not need to include the wire- side sealing members 48 and 49.
As long as the body portion 41 can be inserted from the 2 nd opening portion 114 into the housing space 120 along the opening direction of the 2 nd opening portion, the shapes and sizes of the housing space 120 and the body portion 41 are not limited to those of the above embodiments.
For example, the width of the storage space 120 in the Z direction may be constant from the partition wall 112 to the divided portion 92 when viewed from the Y direction. For example, the cross-sectional area of the housing space 120 taken on a plane perpendicular to the X direction may be increased in stages rather than gradually increasing from the partition wall 112 toward the divider 92 along the X direction. For example, the cross-sectional area of the housing space 120 taken on a plane perpendicular to the X direction may not monotonically increase from the partition wall 112 toward the divider 92 along the X direction. For example, the Z-direction width of the housing space 120 may be equal to the Z-direction width of the body 41.
For example, the width of the main body 41 in the Z direction may be maximized at the other end portion of the main body 41 in the X direction, which is located on the split portion 92 side in the housing space 120. For example, the Z-direction width of the body 41 may be the largest at any position between both ends of the body 41 in the X-direction. For example, the main body 41 may be a main body having a shape other than a rectangle, such as a trapezoid, a triangle, or a stepped portion having a step in the Z direction when viewed from the Y direction.
The width of the 2 nd opening 114 in the Z direction may be equal to the width of the main body 41 in the Z direction. That is, the width of the 2 nd opening 114 in the Z direction may be equal to the maximum width of the main body 41 in the Z direction.
The insertion direction of the wire insertion holes 135 and 136 is not limited to the X direction. That is, the insertion direction of the wire insertion holes 135 and 136 may be the opening direction of the 2 nd opening 114, that is, a direction different from the direction in which the connection portions 61 and 71 are arranged. The shapes of the wire insertion holes 135 and 136 are not limited to those of the above embodiments. For example, the wire insertion holes 135 and 136 may be one hole through which the two wires 33 and 34 are inserted together.
The wire insertion holes 135 and 136 may not be provided in the partition wall 112. The wire insertion holes 135 and 136 may be provided in any one of the side wall 111, the partition wall 112, and the body 92 defining the housing space 120.
The direction of drawing out the electric wires 33, 34 from the main body portion 41 is not limited to the X direction. That is, the direction in which the wires 33 and 34 are drawn out from the body 41 may be the opening direction of the 2 nd opening 114, that is, a direction different from the direction in which the connection portions 61 and 71 are arranged.
The wires 33 and 34 do not have to be drawn out of the body 41 from the portion of the body 41 facing the partition wall 112 in the X direction. That is, the drawing positions P1 and P2 on the outer wall surface of the connector housing 35 may be changed as appropriate. For example, the wires 33 and 34 may be drawn out of the main body 41 from a portion of the main body 41 facing the side wall 111 or a portion facing the separate portion 92.
The lead-out direction of the wires 33, 34 from the main body 41 may be a direction different from the direction in which the 1 st connection part 61 and the 2 nd connection part 71 are arranged.
In the above embodiment, the body portion 41 holds the electrical connection portion of the 1 st terminal 31 and the 1 st electric wire 33 and the electrical connection portion of the 2 nd terminal 32 and the 2 nd electric wire 34 inside. However, the electrical connection portion between the 1 st terminal 31 and the 1 st electric wire 33 and the electrical connection portion between the 2 nd terminal 32 and the 2 nd electric wire 34 may be exposed to the outside of the connector housing 35 or may be disposed outside the connector housing 35.
The shape of the terminal holding portion 42 is not limited to the shape of the above embodiment. The terminal holding portion 42 may be any terminal holding portion that protrudes from the body portion 41 and the connecting portions 61 and 71 protrude from the terminal holding portion 42.
The direction and position in which the wires 33 and 34 are drawn out from the shield case 36 may be changed as appropriate.
In the above embodiment, the 1 st electric wire 33 is crimped to the 1 st electric wire connection portion 62 by being wrapped in the pair of barrel pieces 66 and being tightened together with the barrel pieces 66. However, the method of electrically connecting the 1 st terminal 31 and the 1 st electric wire 33 is not limited thereto. For example, the 1 st terminal 31 and the 1 st electric wire 33 may be electrically connected by welding such as ultrasonic welding. In this case, the 1 st wire connection portion 62 may not include the barrel piece 66. The same applies to the electrical connection between the 2 nd terminal 32 and the 2 nd wire 34.
The shape of the terminals 31 and 32 is not limited to the shape of the above embodiment. The 1 st terminal 31 may have a shape having the 1 st connection part 61 electrically connected to the counterpart terminal 201. The 2 nd terminal may have any shape as long as it has the 2 nd connection part 71 electrically connected to the mating terminal 202.
In the above embodiment, the connector 30 includes two terminals, i.e., the 1 st terminal 31 and the 2 nd terminal 32. However, the number of terminals provided in the connector 30 is not limited to this, and may be plural. The number of wires provided in the connector 30 may be changed as appropriate according to the number of connection portions. For example, the connector 30 may have three terminals. In this case, the connection portions of the three terminals are arranged along the opening direction of the 2 nd opening 114.
The opening direction of the 2 nd opening 114 is not limited to the Y direction perpendicular to the X direction as long as it is a direction intersecting the Y direction which is the opening direction of the 1 st opening 113. The opening direction of the 2 nd opening 114 is an insertion direction when the body portion 41 is inserted into the housing space 120 from the 2 nd opening 114.
When the shield case 36 includes the housing portion 121, and the housing portion 121 includes a wall defining the housing space 120 for housing the body portion 41, and the 1 st opening 113 provided in the wall and communicating the housing space 120 with the outside of the shield case 36, the shield case 36 is not limited to the shape of the above embodiment. Of course, the shape of the 1 st opening 113 and the like may be changed as appropriate. For example, the shield case 36 may have a separate portion 92 without the notch 117. For example, the shield case 36 may not have the inclined surface 165 and the dewatering hole 164. In the above embodiment, the shield case 36 is configured by two members, i.e., the case main body 91 and the separate body 92, but may be configured by three or more members.
The fixing member 171 is not limited to a bolt. The fixing member 171 may be any member such as a screw that can be inserted through the fixing hole 151 to fix the fixing portion 103 and the mounting portion 25.
The shape of the case 23 may be appropriately changed according to the shape of the device 21 housed in the case 23 and the shape of the connector 30.
In the above embodiment, the "1 st direction" as the opening direction of the 1 st opening 113 substantially coincides with the front-rear direction. However, the "1 st direction" may not necessarily coincide with the front-rear direction. The "1 st direction" is not limited to the front-rear direction, and may be another direction depending on the shape of the shield case 36 and the posture of the connector 30. In the above embodiment, the "2 nd direction" which is a direction intersecting the 1 st direction and is the opening direction of the 2 nd opening 114 substantially coincides with the left-right direction. However, the "2 nd direction" is not limited to the left-right direction, and may be changed to another direction depending on the shape of the shield case 36 and the posture of the connector 30. The "2 nd direction" does not necessarily have to intersect the 1 st direction, as long as it intersects the 1 st direction. In the above embodiment, the "3 rd direction" as a direction intersecting the 1 st direction and intersecting the 2 nd direction perpendicularly substantially coincides with the vertical direction. However, the "3 rd direction" is not limited to the vertical direction, and may be another direction depending on the shape of the shield case 36 and the posture of the connector 30. The "3 rd direction" does not necessarily have to intersect the 1 st direction, as long as it intersects the 1 st direction and intersects the 2 nd direction perpendicularly.
In the above embodiment, the inverter 22 is exemplified as the device 21 mounted on the vehicle. However, the device 21 connected to the connector 30 is not limited to this, and may be any electrical device mounted on the vehicle.
In the illustrated embodiment, the Y direction as the protruding direction of the connection portions 61 and 71 of the terminals 31 and 32 may be 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.
In the illustrated embodiment, the mounting portion 25 of the device 21 or a combination of the mounting portion 25 and the mating terminals 201 and 202 may be referred to as a mating connector corresponding to the connector 30. The counterpart connector can be fixedly provided to the housing 23 of the device 21, and may be integrated with the housing 23, for example. The mating connector and the connector 30 may be referred to as a connector pair or a mating pair.
In the illustrated embodiment, the flange portion 51 (particularly, the flange surface) of the connector housing 35 and/or the 1 st opening 113 (particularly, the opening edge) of the shield shell may be configured to contact or face the distal end surface of the mounting portion 25. The flange portion 51 (particularly, flange surface) of the connector housing 35 and/or the 1 st opening 113 (particularly, opening edge) of the shield shell may be referred to as a base surface of the connector 30 or the connector housing 35, and may be parallel to the XZ plane, for example. In the illustrated embodiment, the connector housing 35 may be referred to as an insulating resin base or an insulating resin block.
The connector housing 35 may be closely attached to the entire surfaces of the terminals 31, 32 except the connecting portions 61, 71, or may be closely attached to the 1 st length part having the 1 st length in the outermost of the electric wires 33 and the 2 nd length part having the 2 nd length in the outermost of the electric wires 34. The 2 nd length may be different from the 1 st length.
As in the illustrated embodiment, the connection portions 61 and 71 of the terminals 31 and 32 may be formed as a metal plate, and the metal plate may be formed to extend on a 1 st non-base surface or a 1 st orthogonal surface which intersects or is orthogonal to the flange portion 51 (base surface) of the connector housing 35, and which may be an XY surface, for example. The 1 st connection portion 61 of the 1 st terminal 31 and the 2 nd connection portion 71 of the 2 nd terminal 32 may be arranged on a common virtual plane.
As in the embodiment shown in fig. 6, the 1 st connecting portion 61 and the 1 st connecting portion 63 of the 1 st terminal 31 may be disposed on different planes, for example, XY plane and XZ plane, by interposing the bent portion 65 therebetween. The bent portion 65 of the 1 st terminal 31 may be referred to as an out-of-plane bent portion or an out-of-plane L-shaped portion in which the 1 st connecting portion 61 and the 1 st connecting portion 63 are disposed on different planes, for example, XY planes and XZ planes.
As in the embodiment shown in fig. 6, the direction converter 76 of the 2 nd terminal 32 may be configured to extend the 2 nd connecting part 71 and the 2 nd connecting part 73 on a common virtual plane (for example, XY plane) or to extend in parallel with the common virtual plane (for example, XY plane). The direction changing portion 76 of the 2 nd terminal 32 according to the embodiment may be referred to as an in-plane bent portion or an in-plane L portion in which the 2 nd connecting portion 71 and the 2 nd connecting portion 73 are arranged on a common virtual plane, for example, an XY plane.
As in the embodiments shown in fig. 4 to 6, the connector housing 35 may have a 2 nd non-base surface or a 2 nd orthogonal surface (for example, end surfaces of the wire holding portions 44 and 45) which is different from the flange portion 51 (base surface) of the connector housing 35 and may be, for example, a YZ surface. The lead-out positions P1 and P2 in the illustrated embodiment may be different positions on the 2 nd non-base surface or the 2 nd orthogonal surface of the connector housing 35.
The 1 st wire connection portion 62 of the 1 st terminal 31 and the 2 nd wire connection portion 72 of the 2 nd terminal 32 may be arranged with a gap in the X direction as shown in fig. 6, or may not be partially or completely overlapped with each other in a plan view as viewed from the Z direction as shown in fig. 9. Alternatively or in addition, the wire connecting portions 62 and 72 may be arranged with a shift in the Z direction, for example, as shown in fig. 6, or may not overlap partially or completely, for example, in a plan view seen from the X direction, as shown in fig. 10. As shown in fig. 9 and 10, the wire connecting portions 62 and 72 may be arranged on a common virtual plane that can be an XZ plane.
As in the illustrated embodiment, the connector housing 35 may be configured to regulate the direction in which the wires 33 and 34 are drawn out, and the connector housing 35 may be configured to draw out the wires 33 and 34 from the connector housing 35 in parallel with the flange portion 51 (base surface) orthogonal to the mounting direction of the connector 30, for example.
