Description

Technical Field

[0001] The invention relates to a connector and a fixing structure of the connector. Background Art

[0002] In the past, there was a connector that was assembled to a conductive box of a device, and the device was installed in a vehicle such as a car. Such a connector has, for example, a connector housing, a terminal held in the connector housing, and a shielding shell for suppressing electromagnetic noise radiation from the connector. An electric wire is connected to the terminal. The electric wire is led out from the connector housing.

[0003] For example, in the connector described in patent document 1, the shielding shell is arranged on the outside of the connector housing. The shielding shell has a shell body covering the outer surface of the connector housing and a bolt fixing portion extending from the shell body. A shielding ring is installed on the shell body, and a braided wire covering the outer circumference of the electric wire is sandwiched between the shielding ring and the shell body and fixed. The braided wire is electrically connected to the shielding shell by contacting the outer circumferential surface of the shell body between the shielding ring and the shell body. In addition, the case of the device has a connector assembly surface and a bolt fixing surface orthogonal to the connector assembly surface. The bolt fixing portion has a portion extending along the connector assembly surface and a portion extending along the bolt fixing surface. The bolt fixing portion is fixed to the case by a bolt assembled on the bolt fixing surface. Thus, the shielding shell is electrically connected to the case. Prior art literature Patent Literature

[0004] Patent Document 1: Japanese Patent Application Publication No. 2016-76438 Summary of the invention Problems to be solved by the invention

[0005] When the connector described in Patent Document 1 is fixed to a housing, the connection portion between the shielding shell and the braided wire and the electrical connection portion between the shielding shell and the housing are exposed to the outside of the housing and the connector. Therefore, when the device is arranged in a place where water may be immersed, water may adhere to the connection portion between the shielding shell and the braided wire and the electrical connection portion between the shielding shell and the housing. When water adheres to the connection portion between the shielding shell and the braided wire, the electrical connection between the shielding shell and the braided wire may become unstable. The same is true for the connection portion between the shielding shell and the housing. When water adheres, the electrical connection may become unstable. Therefore, there is a concern that the electromagnetic shielding performance will be reduced.

DETAILED DESCRIPTION

[0011] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. The connector of the present invention, [1] comprising: a connector housing fixed to a conductive housing provided by a device; a terminal held in the connector housing; an electric wire electrically connected to the terminal and led out from the inside of the connector housing to the outside along a first direction; and a shield shell having conductivity, wherein the electric wire is a shielded electric wire having a core wire, a first insulating coating covering the outer periphery of the core wire, an electromagnetic shielding member having conductivity and covering the outer periphery of the first insulating coating, and a second insulating coating covering the outer periphery of the electromagnetic shielding member, wherein the connector housing has an outer configuration portion configured outside the housing and a An inner configuration portion, the shielding shell having a first portion configured inside the outer configuration portion and a second portion configured at a position offset from the first portion in a direction opposite to the first direction, the first portion having a first shielding connection portion electrically connected to the electromagnetic shielding component and covering the outer periphery of a portion of the wire configured inside the outer configuration portion, the second portion having a second shielding connection portion, the second shielding connection portion being fixed to the box body inside the box body and electrically connected to the box body, and the second shielding connection portion being located on the inner side than the outer edge of the connector housing when viewed from the first direction.

[0012] According to this structure, the electrical connection part between the shielding shell and the box body can be arranged inside the box body. In addition, the first part arranged inside the outer arrangement part has a first shield connection part electrically connected to the electromagnetic shielding member. That is, the electrical connection part between the shielding shell and the electromagnetic shielding member is arranged inside the connector housing. As a result, it is possible to suppress the electrical connection part between the shielding shell and the box body and the electrical connection part between the shielding shell and the electromagnetic shielding member from being flooded. Therefore, it is possible to suppress the reduction of electromagnetic shielding performance caused by water adhering to the electrical connection part between the shielding shell and the box body and the electrical connection part between the shielding shell and the electromagnetic shielding member.

[0013] In addition, the second shielding connection portion is located inside the outer edge of the connector housing when viewed from the first direction. Therefore, the second shielding connection portion can be fixed to the housing at a position closer to the electric wire than when the second shielding connection portion is located outside the outer edge of the connector housing when viewed from the first direction. Therefore, when the electric wire vibrates when the second shielding connection portion is fixed to the housing, it is easy to suppress the vibration of the connector relative to the housing.

[0014] [2] In the above [1], the second shield connection portion may have a first through hole, and a bolt that fixes the housing and the second shield connection portion may pass through the first through hole. According to this structure, the second shielding connection part can be easily fixed to the box body by the bolt and the nut assembled to the bolt. In addition, when the second shielding connection part is fixed to the box body by the bolt and the nut, the second shielding connection part is integrated with the box body, so the relative movement of the second shielding connection part with respect to the box body can be further suppressed. Therefore, the vibration of the connector with respect to the box body can be further suppressed.

[0015] [3] In the above [2], the terminal may have a second through hole for passing a terminal fixing bolt for fixing a counterpart terminal arranged inside the box and the terminal through the second through hole, the first through hole passes through the second shielding connection portion in a second direction orthogonal to the first direction, and the second through hole passes through the terminal in the second direction.

[0016] According to this structure, the direction in which the terminal fixing bolt passes through the terminal and the other terminal in order to connect the terminal and the other terminal, and the direction in which the bolt passes through the box and the second shielding connection part in order to fix the second shielding connection part to the box can be made the same direction. Therefore, the connection workability between the second shielding connection part and the box and the connection workability between the terminal and the other terminal can be improved.

[0017] [4] In the above-mentioned [2] or [3], the shield case may include a nut fixed to the first through hole and mounted on the bolt. According to this configuration, the second shield connection part can be easily fixed to the case by inserting the bolt for fixing the second shield connection part to the case into the nut fixed to the first through hole.

[0018] The fixing structure of the connector of the present invention, [5] It comprises: a conductive box provided by the device; a connector housing for holding terminals and electric wires electrically connected to the terminals and led out along a first direction; and a conductive shielding shell, wherein the box has a mounting opening for inserting the terminals and a shielding shell connecting portion provided inside the box, the connector housing has an outer configuration portion provided outside the box and an inner configuration portion provided inside the box, the outer configuration portion has a fixing portion fixed to the outer surface of the box, the electric wire is a shielded electric wire, having a core wire, a first insulating coating covering the outer periphery of the core wire, and an electromagnetic shield having conductivity and covering the outer periphery of the first insulating coating. The shielding member and the second insulating coating layer covering the outer periphery of the electromagnetic shielding member, the shielding shell having a first part arranged inside the outer configuration part and a second part arranged inside the box body together with the inner configuration part, the first part having a first shielding connection part electrically connected to the electromagnetic shielding member and covering the outer periphery of the part of the wire arranged inside the outer configuration part, the second part having a second shielding connection part, the second shielding connection part being located on the inner side than the outer edge of the connector housing when viewed from the first direction, being fixed to the shielding shell connection part inside the box body and being electrically connected to the shielding shell connection part.

[0019] According to this structure, the same effect as the above-mentioned [1] can be achieved. [Details of Embodiments of the Invention] The following is a specific example of the connector and the fixing structure of the connector of the present invention with reference to the accompanying drawings. In each of the drawings, for the convenience of explanation, a part of the structure is sometimes enlarged or simplified. In addition, the size ratios of each part are sometimes different in each of the drawings. In each of the drawings, the X, Y, and Z axes that are orthogonal to each other are shown. The "orthogonal" in this specification not only includes the case of being strictly orthogonal, but also includes the case of being roughly orthogonal within the scope of the effect of the present embodiment. In addition, the term "annular" used in this specification sometimes refers to any structure that forms a ring, i.e., a continuous shape without ends, and a structure that is annular as a whole with a gap such as a C-shape. The shape of the "annular" includes a circle, an ellipse, and a polygon with a sharp or rounded corner, but is not limited to this. In addition, the terms "first", "second", etc. in the present invention are only used to distinguish objects, and do not sort the objects. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all variations within the meaning and scope equivalent to the claims.

[0020] Hereinafter, an embodiment of a connector and a connector fixing structure will be described. like Figure 1 As shown, the connector 20 is disposed at the end of the wiring harness. Figure 1 yes Figure 3 1-1 sectional view in FIG. The connector 20 is arranged in a vehicle. The vehicle has a plurality of devices such as a high-voltage battery, an inverter, and a motor for driving wheels. The connector 20 is mounted on one device 10 among the plurality of devices.

[0021] (Structure of the box 11) The device 10 includes a conductive housing 11. For example, the housing 11 is made of metal such as aluminum or aluminum alloy. The housing 11 is not limited to metal, and may be formed of a conductive resin material.

[0022] The case 11 includes, for example, a box-shaped main body 12 and a shielding shell connection portion 13 disposed inside the main body 12, i.e., inside the case 11. The main body 12 includes an installation opening 14, and the terminal 22 of the connector 20 is inserted into the installation opening 14. The installation opening 14 connects the inside and outside of the main body 12. The installation opening 14 penetrates the side wall of the main body 12, for example, along the X-axis. The shielding shell connection portion 13 is electrically connected to the main body 12. The main body 12 and the shielding shell connection portion 13 are, for example, formed integrally. In addition, the shielding shell connection portion 13 may also be formed separately from the main body 12. In this case, the shielding shell connection portion 13 is electrically connected to the main body 12 by being fixed to the main body 12. The shielding shell connection portion 13 includes, for example, a through hole 15. The through hole 15 penetrates the shielding shell connection portion 13, for example, along the Y-axis.

[0023] (Structure of Connector 20) The connector 20 includes a connector housing 21 fixed to the housing 11 , terminals 22 held in the connector housing 21 , electric wires 23 , and a shield shell 24 having conductivity.

[0024] (Structure of Connector Housing 21) like Figure 1 and Figure 2 As shown, the connector housing 21 includes, for example, a first housing 31 , a second housing 41 , and a third housing 61 .

[0025] The first housing 31 is made of, for example, synthetic resin. The first housing 31 includes, for example, a cylindrical portion 32 extending in a cylindrical shape along the first direction D1 and a fixing portion 33 integrally provided on the outer peripheral surface of the cylindrical portion 32. The first direction D1 is a direction from the inside of the housing 11 to the outside through the mounting opening 14. The first direction D1 is, for example, a direction along the X-axis ( Figure 1In addition, a direction orthogonal to the first direction D1 is referred to as the second direction D2. The second direction D2 is, for example, a direction along the Z axis. In addition, a direction orthogonal to the first direction D1 and to the second direction D2 is referred to as the third direction D3. The third direction D3 is, for example, a direction along the Y axis. Hereinafter, unless otherwise specified, the first direction D1, the second direction D2, and the third direction D3 are directions in the assembled state of the connector 20.

[0026] The fixing portion 33 extends, for example, in a flange shape from an end region of the cylindrical portion 32 in a direction opposite to the first direction D1 toward the outside of the cylindrical portion 32. The fixing portion 33 is, for example, formed in a ring shape surrounding the cylindrical portion 32. The fixing portion 33 has an opposing surface 34 that faces the outer surface of the housing 11. For example, the opposing surface 34 is an end surface in a direction opposite to the first direction D1 of the two end surfaces of the fixing portion 33 in the first direction D1. For example, the opposing surface 34 is formed in a plane shape perpendicular to the first direction D1.

[0027] like Figure 1 and Figure 3 As shown, the fixing portion 33 may also include a sealing groove 35 that is recessed from the opposing surface 34 toward the first direction D1. When viewed from the first direction D1, the sealing groove 35 forms a ring shape surrounding the cylindrical portion 32. The connector 20 may also include a first sealing member 36 disposed in the sealing groove 35. The first sealing member 36 is, for example, a rubber seal ring.

[0028] The fixing portion 33 has, for example, four fixing holes 37. In addition, the number of the fixing holes 37 of the fixing portion 33 is not limited to four, and may be a plurality. Each fixing hole 37 penetrates the fixing portion 33 in the first direction D1. When viewed from the first direction D1, each fixing hole 37 is located outside the sealing groove 35. In addition, when viewed from the first direction D1, the plurality of fixing holes 37 are separated at equal intervals, for example, along the outer edge 31A of the fixing portion 33. A ring-shaped metal collar 38 may also be installed on the inner circumferential surface of each fixing hole 37.

[0029] The first shell 31 is fixed to the outer peripheral portion of the mounting port 14 in the main body 12 of the housing 11. When viewed from the first direction D1, the first shell 31 is arranged in the housing 11 in such a manner that the mounting port 14 is arranged on the inner side of the cylindrical portion 32. In addition, the first shell 31 is arranged in the housing 11 so that the opposing surface 34 faces the outer surface of the main body 12. The first shell 31 is fixed to the main body 12 by screws (not shown) that penetrate the fixing holes 37. In addition, the first sealing member 36 is in close contact with the inner surface of the sealing groove 35 and the outer surface of the housing 11, thereby sealing between the outer surface of the housing 11 and the fixing portion 33. That is, the first sealing member 36 prevents water from penetrating into the interior of the housing 11 or the interior of the connector 20 from between the outer surface of the housing 11 and the fixing portion 33.

[0030] like Figure 1 and Figure 2 As shown, the second housing 41 includes, for example, a second housing body 42 having a cylindrical shape extending in the first direction D1 and an outer fitting portion 43 integrally provided on the outer peripheral surface of the second housing body 42. The second housing 41 is made of, for example, synthetic resin.

[0031] The second housing body 42 has a first end 42a and a second end 42b on the opposite side of the first end 42a in the first direction D1. The second housing 41 may also have a protruding opening 44, and the terminal 22 protrudes from the protruding opening 44 in the direction opposite to the first direction D1. The protruding opening 44 is located at the first end 42a of the second housing body 42. In addition, the second housing 41 has a through opening 45, and the electric wire 23 passes through the through opening 45 in the first direction D1. The through opening 45 is located at the second end 42b of the second housing body 42.

[0032] The second housing body 42 is arranged to be inserted into the inner side of the cylindrical portion 32. In addition, the second housing body 42 is inserted into the interior of the housing 11 through the mounting opening 14, for example. For example, the first end 42a of the second housing body 42 is arranged inside the housing 11, and the second end 42b is arranged outside the housing 11.

[0033] The second housing body 42 has an exposed recess 51, for example, in an end region including the first end 42a of the second housing body 42. The exposed recess 51 is located at the end of the second housing body 42 in the second direction D2. The exposed recess 51 is recessed from the first end 42a toward the first direction D1. The interior of the second housing body 42 is exposed to the outside of the second housing body 42 from the exposed recess 51. The exposed recess 51 is arranged inside the housing 11.

[0034] like Figure 1 As shown, the outer fitting portion 43 includes a bottom wall 47 extending in a flange shape from the outer peripheral surface of the second case body 42, and an annular fitting portion 48 extending in a direction opposite to the first direction D1 from the outer edge of the bottom wall 47. The cylindrical portion 32 fits inside the fitting portion 48.

[0035] A second sealing member 49 is disposed between the outer circumferential surface of the second housing body 42 and the inner circumferential surface of the cylindrical portion 32. The second sealing member 49 is disposed inside the outer fitting portion 43. The second sealing member 49 is, for example, a rubber seal. The second sealing member 49 seals between the inner circumferential surface of the cylindrical portion 32 and the outer circumferential surface of the second housing body 42. That is, the second sealing member 49 prevents water from penetrating into the interior of the box 11 or the interior of the connector 20 from between the outer circumferential surface of the second housing body 42 and the inner circumferential surface of the cylindrical portion 32.

[0036] like Figure 2As shown, the second housing body 42 may also have a first engaging portion 52. For example, a first engaging portion 52 is provided on each of the two side surfaces of the second housing body 42. Each first engaging portion 52 is, for example, a portion between a pair of grooves provided in the top end region of the second housing body 42 including the first end 42a. Each first engaging portion 52 has an engaging hole 53. Each first engaging portion 52 can be elastically deformed in a manner that the top end is offset relative to the base end thereof along the third direction D3.

[0037] like Figure 1 and Figure 4 As shown, the third housing 61 includes, for example, a first split housing 62 and a second split housing 63 assembled to the first split housing 62. The first split housing 62 and the second split housing 63 are each made of, for example, resin. The second split housing 63 overlaps with the first split housing 62 at a position offset in the second direction D2 from the first split housing 62. In addition, the second split housing 63 is fixed to the first split housing 62.

[0038] The first split housing 62 includes, for example, a first terminal holding portion 64 and a first wire holding portion 65. The second split housing 63 includes, for example, a second terminal holding portion 66 and a second wire holding portion 67. The second terminal holding portion 66 overlaps with the first terminal holding portion 64 at a position offset in the second direction D2 from the first terminal holding portion 64. The third housing 61 holds the terminal 22 between the first terminal holding portion 64 and the second terminal holding portion 66.

[0039] The first terminal holding portion 64 has, for example, a first terminal exposure opening 68. The second split housing 63 has, for example, a second terminal exposure opening 69. The first terminal exposure opening 68 and the second terminal exposure opening 69 are arranged in the second direction D2. A portion of the terminal 22 is arranged between the first terminal exposure opening 68 and the second terminal exposure opening 69. Both end surfaces in the second direction D2 of the portion of the terminal 22 located between the first terminal exposure opening 68 and the second terminal exposure opening 69 are exposed to the outside of the connector 20 from the first terminal exposure opening 68 and the second terminal exposure opening 69.

[0040] The first wire holding portion 65 extends, for example, from an end portion of the first terminal holding portion 64 in the first direction D1 toward the first direction D1. The second wire holding portion 67 extends, for example, from an end portion of the second terminal holding portion 66 in the first direction D1 toward the first direction D1. The third housing 61 holds an end region of the wire 23 in a direction opposite to the first direction D1 between the first wire holding portion 65 and the second wire holding portion 67. The first wire holding portion 65 and the second wire holding portion 67 overlap, for example, in a manner of sandwiching the wire 23 from both sides in the second direction D2. The first wire holding portion 65 and the second wire holding portion 67 overlapped with each other form a cylindrical shape extending in the first direction D1.

[0041] like Figure 1 As shown, the third housing 61 has a wire insertion opening 71, and the wire 23 passes through the wire insertion opening 71 in the first direction D1. For example, the wire insertion opening 71 is located at the end of the third housing 61 in the first direction D1, that is, the end of the first wire holding portion 65 and the second wire holding portion 67 in the first direction D1. The third housing 61 is inserted into the interior of the second housing body 42 along the first direction D1 in such a manner that the wire insertion opening 71 is arranged inside the second housing body 42. The first terminal holding portion 64 and the second terminal holding portion 66 protrude from the protruding opening 44 to the outside of the second housing body 42 in the direction opposite to the first direction D1.

[0042] like Figure 2 As shown, the third housing 61 may also have a second engaging portion 72, and the second engaging portion 72 is embedded in the first engaging portion 52 of the second housing 41. For example, the third housing 61 has the second engaging portion 72 at both ends of the first split housing 62 in the third direction D3. The second engaging portion 72 is, for example, a protrusion that protrudes from the outer surface of the first split housing 62 in the Y-axis direction. The third housing 61 is inserted into the inner side of the second housing 41 along the first direction D1. And, by embedding the second engaging portion 72 into the engaging hole 53 of the first engaging portion 52 on both sides of the third housing 61 in the third direction D3, the second housing 41 and the third housing 61 are fixed.

[0043] (Structure of terminal 22) like Figure 1 As shown, the terminal 22 is formed, for example, in a flat plate shape orthogonal to the second direction D2. The terminal 22 is formed, for example, of a metal material such as copper, copper alloy, aluminum, or aluminum alloy. The electric wire 23 is electrically connected to the terminal 22. The terminal 22 and the electric wire 23 are joined, for example, by crimping, ultrasonic welding, laser welding, or other known joining methods. The third housing 61 accommodates the electrically connected portion of the electric wire 23 and the terminal 22 between the first split housing 62 and the second split housing 63.

[0044] The terminal 22 may also have a second through hole 25, and a terminal fixing bolt 202 for fixing the counterpart terminal 201 disposed inside the housing 11 and the terminal 22 is passed through the second through hole 25. The second through hole 25 passes through the terminal 22 in the second direction D2, for example. The second through hole 25 is exposed to the outside of the connector 20 from the first terminal exposure opening 68 and the second terminal exposure opening 69.

[0045] (Structure of the electric wire 23) like Figure 5 As shown, the electric wire 23 is a shielded electric wire having an electromagnetic shielding structure. Figure 5 yes Figure 1A partially enlarged view of the core wire 81. The electric wire 23 has a core wire 81 composed of a conductor, a first insulating coating 82 covering the outer periphery of the core wire 81, an electromagnetic shielding member 83 covering the outer periphery of the first insulating coating 82, and a second insulating coating 84 covering the outer periphery of the electromagnetic shielding member 83. The electric wire 23 is, for example, a high-voltage electric wire that can cope with high voltage and large current. As the material of the core wire 81, for example, a metal material such as copper or aluminum can be used. The first insulating coating 82 and the second insulating coating 84 are respectively composed of an insulating material such as a synthetic resin. The electromagnetic shielding member 83 is, for example, a braided wire in which conductive wires such as copper alloys and aluminum alloys are braided into a cylindrical shape.

[0046] The electric wire 23 extends along the first direction D1. The electric wire 23 is led out from the inside of the connector housing 21 to the outside along the first direction D1. That is, the first direction D1 is the direction in which the electric wire 23 is led out from the inside of the connector housing 21 to the outside. The electric wire 23 passes through the electric wire through-hole 71 and extends to the outside of the third housing 61, and passes through the through-hole 45 and extends to the outside of the second housing 41, that is, the outside of the connector housing 21.

[0047] The connector 20 may also include a third sealing member 85 that seals between the inner circumferential surface of the second housing body 42 and the outer circumferential surface of the electric wire 23. The third sealing member 85 is disposed between the inner circumferential surface of the end region including the second end 42b in the second housing body 42 and the outer circumferential surface of the electric wire 23. The third sealing member 85 is located at a position offset in the first direction D1 from the third housing 61. The third sealing member 85 is, for example, a rubber seal. The third sealing member 85 prevents water from penetrating into the interior of the connector 20 from the through-hole 45.

[0048] like Figure 1 and Figure 2 As shown, the connector 20 may also include a rear retaining body 86, which is mounted on the end region including the second end 42b in the second housing body 42. The rear retaining body 86 prevents the third sealing member 85 from falling off from the second housing 41. The rear retaining body 86 includes, for example, split retaining bodies 87a and 87b that are split into two in the third direction D3 and a fixing member 88 that fixes the split retaining bodies 87a and 87b to the second housing 41. The fixing member 88 is, for example, annular. The fixing member 88 is embedded in the outer side of the split retaining bodies 87a and 87b. In addition, the electric wire 23 passes through the rear retaining body 86 in the first direction D1.

[0049] like Figure 5As shown, the first insulating coating 82 is exposed in a portion of the electric wire 23 arranged inside the third housing 61. For example, the second insulating coating 84 is removed from the range from the end of the electric wire 23 in the direction opposite to the first direction D1 to the outside of the third housing 61 and the position near the electric wire through-hole 71. In addition, the first fixing member 89 is fixed to the electric wire 23. The first fixing member 89 is, for example, located inside the second housing body 42 and between the electric wire through-hole 71 and the through-hole 45 in the first direction D1. In detail, the first fixing member 89 is located between the electric wire through-hole 71 and the third sealing member 85. The first fixing member 89 is attached to the outer periphery of the end region of the second insulating coating 84 in the direction opposite to the first direction D1. The first fixing member 89 is, for example, a metal clamping ring.

[0050] For example, the electromagnetic shield member 83 has a folded portion 83a folded back in the first direction D1 at an end region in the direction opposite to the first direction D1. The folded portion 83a overlaps with an end region of the second insulating coating layer 84 in the direction opposite to the first direction D1 so as to cover the outer peripheral surface of the first fixing member 89.

[0051] (Structure of Shield Case 24) like Figure 1 and Figure 4 As shown, the shield case 24 includes, for example, a first covering portion 101 and a second covering portion 111. The first covering portion 101 and the second covering portion 111 are disposed on both sides of the third housing 61 in the second direction D2. The first covering portion 101 and the second covering portion 111 are each formed by, for example, stamping a metal plate.

[0052] like Figure 4 and Figure 5As shown, the first covering portion 101 has a first connection portion 102, for example, in an end region in the first direction D1. The second covering portion 111 has a second connection portion 112, for example, in an end region in the first direction D1. In addition, for example, the first connection portion 102 and the second connection portion 112 correspond to the "first shielding connection portion". The shape of each of the first connection portion 102 and the second connection portion 112, for example, as viewed from the first direction D1, is semicircular. The first connection portion 102 covers the outer peripheral surface of the first wire holding portion 65. The second connection portion 112 covers the outer peripheral surface of the second wire holding portion 67. In addition, the first connection portion 102 and the second connection portion 112 cover the outer peripheral surface of the folded portion 83a. And, the inner surface of each of the first connection portion 102 and the second connection portion 112 is in contact with the outer peripheral surface of the folded portion 83a. When the connector 20 is fixed to the housing 11, the first connection portion 102 and the second connection portion 112 further cover the outer circumference of the portion of the electric wire 23 that is arranged outside the housing 11 and is not covered by the electromagnetic shielding member 83. The first connection portion 102 and the second connection portion 112 are arranged inside the second housing body 42.

[0053] The first covering portion 101 and the second covering portion 111 are fixed to the electric wire 23 by the second fixing member 121. The second fixing member 121 is located inside the second housing body 42 and between the electric wire through-hole 71 and the through-hole 45 in the first direction D1. Specifically, the second fixing member 121 is located between the electric wire through-hole 71 and the third sealing member 85. The second fixing member 121 is mounted on the outer periphery of the first connection portion 102 and the second connection portion 112 and is located between the first connection portion 102, the second connection portion 112 and the folded portion 83a. The second fixing member 121 is, for example, a metal clamping ring. The second fixing member 121 fastens the first connection portion 102 and the second connection portion 112 and the electric wire 23 so that the first connection portion 102 and the second connection portion 112 are in close contact with the folded portion 83a. As a result, the electromagnetic shielding member 83 and the first covering portion 101 and the second covering portion 111 are electrically connected to each other.

[0054] like Figure 1 and Figure 4As shown, the second covering portion 111 has a second shielding connection portion 113, for example, at a position offset from the second connection portion 112 in a direction opposite to the first direction D1. For example, the second shielding connection portion 113 is connected to the second connection portion 112 by a connecting covering portion 114 extending from an end of the second connection portion 112 in a direction opposite to the first direction D1 to the second direction D2. The connecting covering portion 114 covers the end surface of the second terminal holding portion 66 in the first direction D1. The second shielding connection portion 113 is formed in a flat plate shape orthogonal to the second direction D2, for example. When viewed from the direction opposite to the second direction D2, the second shielding connection portion 113 covers, for example, a portion between the second terminal exposure opening 69 and the second wire holding portion 67 in the third housing 61.

[0055] like Figure 1 As shown in FIG. 1 , the end region of the second shielding connection portion 113 in the direction opposite to the first direction D1 protrudes from the second housing 41 in the direction opposite to the first direction D1. The end region of the second shielding connection portion 113 in the first direction D1 is located at a position overlapping with the exposed recess 51 of the second housing 41 in the second direction D2. Therefore, the end surface of the second shielding connection portion 113 in the second direction D2 is exposed to the outside of the connector housing 21 as a whole.

[0056] like Figure 3 As shown, in the connector 20, when viewed from the first direction D1, the second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21. For example, when viewed from the first direction D1, the second shield connection portion 113 is located inside the outer edge 31A of the fixing portion 33 of the first housing 31. Also, for example, when viewed from the first direction D1, the second shield connection portion 113 is located inside the outer edge 41A of the second housing 41. In addition, the outer edge 41A is located at the inner side of the second housing 41. Figure 1 and Figure 2 Medium picture.

[0057] like Figure 1 and Figure 4 As shown, the second shielding connection part 113 has a first through hole 115, and a bolt 122 for fixing the shielding shell connection part 13 of the box body 11 and the second shielding connection part 113 passes through the first through hole 115. The first through hole 115 passes through the second shielding connection part 113 in the second direction D2, for example. For example, the first through hole 115 is located at a position offset in the first direction D1 than the second through hole 25. In addition, for example, when viewed from the second direction D2, the first through hole 115 and the second through hole 25 are arranged in the first direction D1.

[0058] like Figure 6As shown, the shield shell 24 may also include a nut 123, which is fixed to the first through hole 115 and assembled to the bolt 122. The nut 123 is, for example, located between the second shield connection portion 113 and the second terminal holding portion 66 in the second direction D2. For example, the nut 123 is fixed to the first through hole 115 by being pressed.

[0059] Next, a procedure for fixing the connector 20 to the housing 11 will be described. like Figure 1 As shown in FIG. 1 , first, the first housing 31 is fixed to the outer peripheral portion of the mounting opening 14 of the main body 12 of the housing 11. Then, the second housing 41 and the third housing 61, which are fixed to each other, are assembled to the first housing 31. In addition, components other than the first housing 31, the first sealing member 36, and the collar in the connector 20, such as the electric wire 23 and the terminal 22, are pre-assembled in the second housing 41 and the third housing 61. When the second housing 41 and the third housing 61 are assembled to the first housing 31, the first terminal holding portion 64, the second terminal holding portion 66, the terminal 22, and the second shielding connection portion 113 are inserted into the housing 11 through the cylindrical portion 32 and the mounting opening 14. And, the second shielding connection portion 113 is arranged in the housing 11 at a position overlapping with the shield shell connection portion 13 in the second direction D2.

[0060] Then, inside the housing 11, the bolt 122 is inserted into the through hole 15 and the first through hole 115 from the direction opposite to the second direction D2, and the bolt 122 is embedded in the nut 123. At this time, a tool for tightening the bolt 122 and the nut 123 is inserted into the housing 11 from, for example, an opening provided in the housing 11 at a position different from the mounting opening 14. By being fastened by the nut 123 and the bolt 122, the second shielding connection portion 113 is fixed to the shielding shell connection portion 13 inside the housing 11 and is electrically connected thereto. And, when the second shielding connection portion 113 is fixed to the shielding shell connection portion 13, the fixing of the connector 20 to the housing 11 is completed.

[0061] In addition, the connection between the terminal 22 and the other terminal 201 can be performed before or after the connection between the second shield connection part 113 and the shield shell connection part 13 is performed. The terminal 22 and the other terminal 201 are fixed and electrically connected to each other by a terminal fixing bolt 202 that passes through the second through hole 25 and the other terminal 201, and a nut 203 assembled on the terminal fixing bolt 202. For example, the terminal fixing bolt 202 is inserted into the second through hole 25 from the direction opposite to the second direction D2, similarly to the bolt 122. In addition, the terminal fixing bolt 202 can also pass through the other terminal 201 and the terminal 22 from the second direction D2. In addition, a tool for tightening the terminal fixing bolt 202 and the nut 203 is inserted into the inside of the box 11 from an opening provided in the box 11 at a position different from the mounting opening 14, similarly to the tool for tightening the bolt 122 and the nut 123.

[0062] exist Figure 1 In FIG. 1 , a boundary B1 between an outer region A1 as an outer region of the housing 11 and an inner region A2 as an inner region of the housing 11 is illustrated by a single dashed line. For example, the boundary B1 is located on the outer surface of the housing 11. The connector housing 21 has an outer configuration portion 21X configured outside the housing 11 and an inner configuration portion 21Y configured inside the housing 11. That is, the connector housing 21 has an outer configuration portion 21X configured in the outer region A1 and an inner configuration portion 21Y configured in the inner region A2. Figure 1 The outer arrangement portion 21X is a portion of the connector housing 21 arranged in a range offset from the boundary B1 in the first direction D1. The inner arrangement portion 21Y is a portion of the connector housing 21 arranged in a range offset from the boundary B1 in a direction opposite to the first direction D1.

[0063] For example, the first housing 31 is included in the outer arrangement portion 21X. Therefore, the outer arrangement portion 21X has a fixing portion 33 fixed to the outer surface of the housing 11. In addition, the shielding shell 24 includes a first portion 24X disposed inside the outer arrangement portion 21X and a second portion 24Y disposed at a position offset from the first portion 24X in a direction opposite to the first direction D1. The first portion 24X is a portion of the shielding shell 24 disposed in the outer area A1. The second portion 24Y is a portion of the shielding shell 24 disposed in the inner area A2. The first portion 24X includes a first connection portion 102 and a second connection portion 112 electrically connected to the electromagnetic shielding member 83, and covers the outer periphery of a portion of the electric wire 23 disposed inside the outer arrangement portion 21X. The second portion 24Y includes a second shield connection portion 113, which is fixed to the box body 11 inside the box body 11 and is electrically connected to the box body 11.

[0064] The effects of this embodiment will be described. (1) The connector 20 includes a connector housing 21 and a terminal 22 held by the connector housing 21, and the connector housing 21 is fixed to the conductive housing 11 of the device 10. The connector 20 further includes an electric wire 23 and a conductive shield shell 24, and the electric wire 23 is electrically connected to the terminal 22 and is led out from the inside of the connector housing 21 to the outside along the first direction D1. The electric wire 23 is a shielded electric wire, and includes a core wire 81, a first insulating coating 82 covering the outer periphery of the core wire 81, an electromagnetic shield member 83 having conductivity and covering the outer periphery of the first insulating coating 82, and a second insulating coating 84 covering the outer periphery of the electromagnetic shield member 83. The connector housing 21 includes an outer side arrangement portion 21X arranged outside the housing 11 and an inner side arrangement portion 21Y arranged inside the housing 11. The shield shell 24 includes a first portion 24X arranged inside the outer side arrangement portion 21X and a second portion 24Y arranged at a position offset from the first portion 24X in the direction opposite to the first direction D1. The first portion 24X includes a first connection portion 102 and a second connection portion 112 electrically connected to the electromagnetic shielding member 83, and covers the outer periphery of the portion of the electric wire 23 arranged inside the outer arrangement portion 21X. The second portion 24Y includes a second shield connection portion 113, which is fixed to the box body 11 inside the box body 11 and electrically connected to the box body 11. The second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 when viewed from the first direction D1.

[0065] According to this structure, the electrically connected portion between the shield shell 24 and the housing 11 can be arranged inside the housing 11. In the present embodiment, the electrically connected portion between the shield shell 24 and the housing 11 is a portion where the shield shell connecting portion 13 and the second shield connecting portion 113 are in contact. In addition, the first portion 24X arranged inside the outer arrangement portion 21X has the first connecting portion 102 and the second connecting portion 112 electrically connected to the electromagnetic shielding member 83. That is, the electrically connected portion between the shield shell 24 and the electromagnetic shielding member 83 is arranged inside the connector housing 21. In the present embodiment, the electrically connected portion between the shield shell 24 and the housing 11 is a portion where the first connecting portion 102 and the second connecting portion 112 are in contact with the electromagnetic shielding member 83. Thus, it is possible to suppress water from entering the electrically connected portion between the shield shell 24 and the housing 11 and the electrically connected portion between the shield shell 24 and the electromagnetic shielding member 83. Therefore, it is possible to suppress a decrease in electromagnetic shielding performance caused by water adhering to the electrically connected portions between the shield case 24 and the housing 11 and the electrically connected portions between the shield case 24 and the electromagnetic shield member 83 .

[0066] In addition, the second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 when viewed from the first direction D1. Therefore, the second shield connection portion 113 can be fixed to the housing 11 at a position closer to the electric wire 23 than when it is located outside the outer edge 21A of the connector housing 21 when viewed from the first direction D1. Therefore, when the electric wire 23 vibrates when the second shield connection portion 113 is fixed to the housing 11, it is easy to suppress the vibration of the connector 20 relative to the housing 11.

[0067] In addition, when the electric wire 23 is a high-voltage electric wire that can cope with high voltage and large current, the diameter of the electric wire 23 is generally thicker. When the diameter of the electric wire 23 is thicker, when the electric wire 23 vibrates, the connector 20 is easily affected by the vibration of the electric wire 23. In the connector 20 of this embodiment, even if such an electric wire 23 is provided, the second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 when viewed from the first direction D1, so it is easy to suppress the vibration of the connector 20 caused by the vibration of the electric wire 23.

[0068] (2) The second shielding connection part 113 has a first through hole 115, and a bolt 122 for fixing the housing 11 and the second shielding connection part 113 is inserted through the first through hole 115. According to this structure, the second shielding connection part 113 can be easily fixed to the housing 11 by the bolt 122 and the nut 123 assembled to the bolt 122. In addition, when the second shielding connection part 113 is fixed to the housing 11 by the bolt 122 and the nut 123, the second shielding connection part 113 is integrated with the housing 11, so that the relative movement of the second shielding connection part 113 with respect to the housing 11 can be further suppressed. Therefore, the vibration of the connector 20 with respect to the housing 11 can be further suppressed.

[0069] (3) The terminal 22 has a second through hole 25, and a terminal fixing bolt 202 for fixing the mating terminal 201 disposed inside the housing 11 and the terminal 22 is passed through the second through hole 25. The first through hole 115 passes through the second shield connection portion 113 in the second direction D2 orthogonal to the first direction D1. The second through hole 25 passes through the terminal 22 in the second direction D2.

[0070] According to this structure, the direction in which the terminal fixing bolt 202 passes through the terminal 22 and the other terminal 201 in order to connect the terminal 22 and the other terminal 201 and the direction in which the bolt 122 passes through the box body 11 and the second shielding connection part 113 in order to fix the second shielding connection part 113 to the box body 11 can be made the same direction. Therefore, the connection workability between the second shielding connection part 113 and the box body 11 and the connection workability between the terminal 22 and the other terminal 201 can be improved.

[0071] (4) The shield shell 24 has a nut 123, and the nut 123 is fixed to the first through hole 115 and assembled to the bolt 122. According to this structure, the second shield connection part 113 can be easily fixed to the case 11 by inserting the bolt 122 for fixing the second shield connection part 113 to the case 11 into the nut 123 fixed to the first through hole 115.

[0072] (5) The fixing structure of the connector 20 includes the conductive housing 11 of the device 10. The fixing structure of the connector 20 further includes a connector housing 21 and a conductive shield shell 24, and the connector housing 21 holds the terminal 22 and the electric wire 23 electrically connected to the terminal 22 and led out along the first direction D1. The housing 11 has an installation port 14 for inserting the terminal 22 and a shield shell connection portion 13 provided inside the housing 11. The connector housing 21 has an outer configuration portion 21X configured outside the housing 11 and an inner configuration portion 21Y configured inside the housing 11. The outer configuration portion 21X has a fixing portion 33 fixed to the outer surface of the housing 11. The electric wire 23 is a shielded electric wire, and includes a core wire 81, a first insulating coating 82 covering the outer periphery of the core wire 81, an electromagnetic shield member 83 having conductivity and covering the outer periphery of the first insulating coating 82, and a second insulating coating 84 covering the outer periphery of the electromagnetic shield member 83. The shield shell 24 includes a first portion 24X disposed inside the outer arrangement portion 21X and a second portion 24Y disposed inside the housing 11 together with the inner arrangement portion 21Y. The first portion 24X includes a first connection portion 102 and a second connection portion 112 electrically connected to the electromagnetic shielding member 83, and covers the outer periphery of the portion of the electric wire 23 disposed inside the outer arrangement portion 21X. The second portion 24Y includes a second shield connection portion 113. The second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 when viewed from the first direction D1, and is fixed to the shield shell connection portion 13 inside the housing 11 and electrically connected to the shield shell connection portion 13. According to this structure, the same effect as that of the above (1) can be achieved.

[0073] (6) In order to prevent the electrical connection between the shielding shell and the case and the electrical connection between the shielding shell and the electromagnetic shielding member from being immersed in water, it is considered that the connector has a cover that covers the entire outer surface of the connector shell fixed to the case. However, in this case, the connector will be larger. In contrast, in the present embodiment, the electrical connection between the shielding shell 24 and the case 11 is arranged inside the case 11, and the electrical connection between the shielding shell 24 and the electromagnetic shielding member 83 is arranged inside the connector shell 21. Therefore, compared with the case where the connector has a cover, the size of the connector 20 can be prevented from being increased, and the electrical connection between the shielding shell 24 and the case 11 and the electrical connection between the shielding shell 24 and the electromagnetic shielding member 83 can be prevented from being immersed in water. In addition, since the component of the connector 20 does not need to have a cover, the increase in the number of components can be prevented.

[0074] This embodiment can be implemented as the following modifications. This embodiment and the following modifications can be implemented in combination with each other within the range that there is no technical contradiction. The nut 123 may not be fixed to the first through hole 115 by press-fitting. For example, the nut 123 may be fixed to the shield shell 24 by bonding or welding. In addition, the nut 123 may be held by the connector housing 21. In addition, the nut 123 may be prepared separately from the shield shell 24 and the connector housing 21. In this case, when the connector 20 is fixed to the housing 11, the nut 123 is assembled on the bolt 122 that penetrates the shield shell connection portion 13 and the second shield connection portion 113.

[0075] In the above embodiment, the connector 20 includes the nut 123 for fixing the shield shell connection part 13 and the second shield connection part 113. However, the connector 20 may not include the bolt 122 for fixing the shield shell connection part 13 and the second shield connection part 113.

[0076] The second through hole 25 may penetrate the terminal 22 in a direction different from the second direction D2. In addition, the first through hole 115 may penetrate the second shield connection portion 113 in a direction different from the second direction D2. In addition, the penetration directions of the first through hole 115 and the second through hole 25 may be different from each other.

[0077] The second shielding connection part 113 and the shielding shell connection part 13 may be fixed by a method other than bolt fastening using the bolts 122 and the nuts 123. For example, the second shielding connection part 113 and the shielding shell connection part 13 may be fixed by a clamp that clamps the second shielding connection part 113 and the shielding shell connection part 13. In addition, for example, the shielding shell connection part 13 may be formed in the shape of a clamp that clamps the second shielding connection part 113 or in the shape of a female terminal into which the second shielding connection part 113 is embedded. In addition, for example, the second shielding connection part 113 and the shielding shell connection part 13 may be fixed by welding or crimping. In these cases, the second shielding connection part 113 may not have the first through hole 115. In addition, the shielding shell connection part 13 may not have the through hole 15. The fixing method of the terminal 22 and the counterpart terminal 201 may be changed in the same manner.

[0078] The connector housing 21 is not limited to the shape and structure of the above embodiment as long as it has the outer arrangement portion 21X arranged outside the housing 11 and the inner arrangement portion 21Y arranged inside the housing 11. For example, the first housing 31 and the second housing 41 may be integrally formed.

[0079] The shielding shell 24 is not limited to the shape and structure of the above-mentioned embodiment as long as it has the first part 24X arranged inside the outer arrangement part 21X and the second part 24Y arranged at a position offset in the direction opposite to the first direction D1 relative to the first part 24X. For example, the first covering part 101 and the second covering part 111 may be formed integrally. In addition, for example, the shielding shell 24 may be composed of a plurality of parts divided into a plurality of parts in the first direction D1.

[0080] The number of terminals 22 provided in the connector 20 is not limited to one, but may be plural. In this case, for example, the plurality of terminals 22 are arranged in a row along a direction perpendicular to the first direction D1. Furthermore, one electric wire 23 is electrically connected to each of the terminals 22.

[0081] The second direction D2 may be a direction opposite to the second direction D2 in the above embodiment. The third direction D3 may be a direction opposite to the third direction D3 in the above embodiment. The embodiments disclosed herein are to be considered in all respects as illustrative rather than restrictive. The scope of the present invention is indicated by the claims rather than the above, and is intended to include all modifications within the meaning and scope equivalent to the claims.
