Description

[Technical Field]The present disclosure relates to a connector and a connector fixing structure.[Prior Art]From the prior art, a connector is known which is mounted on an electrically conductive enclosure of a device to be installed in a vehicle, such as a motor vehicle. Such a connector includes, for example, a connector housing, a terminal to be held in the connector housing, and a shield shell for suppressing emission of electromagnetic noise from the connector. A wire is connected to the terminal. The wire is pulled out of the connector housing.For example, in a connector described in Patent Literature 1, a shield shell is disposed outside a connector housing. The shield shell includes a shell body for covering the outer surface of the connector housing and a screw fixing portion extending from the shell body. A shield ring is mounted on the sheath body to fix a braided wire for covering the outer periphery of the wire by sandwiching the braided wire between the sheath body and the shield ring. The braided wire is electrically connected to the shield shell by contacting the outer circumferential surface of the shell body between the shield ring and the shell body. Further, a casing of a device has a connector mounting surface and a screw fixing surface orthogonal to the connector mounting surface. The screw fixing portion includes a part extending along the connector mounting surface and a part extending along the screw fixing surface. The screw fixing portion is fixed to the bezel by a screw mounted on the screw fixing surface. Thereby, the shield shell is electrically connected to the enclosure.[Literature List][Patent Literature]Patent Literature 1: Japanese Unexamined Patent Publication No. 2016-76438[Summary of the Invention][Problem to be Solved by the Invention]In the case of fixing the connector described in Patent Literature 1 to the bezel, a connected part of the shield shell and the braided wire and an electrically connected part of the shield shell and the bezel are exposed to the outside of the bezel and the connector. Thus, when the device is disposed at a location where it can be humidified, water may adhere to the connected part of the shield shell and the braided wire and the electrically connected part of the shield shell and the bezel. When water adheres to the joined part of the shield shell and the braided wire, the electrical connection of the shield shell and the braided wire may become unstable. Similarly, the electrical connection may become unstable when water adheres to the connected part of the shield shell and the bezel. Thus, there is a concern that the electromagnetic shielding performance is reduced.The present invention aims to provide a connector and a connector fixing structure capable of preventing a decrease in electromagnetic shielding performance.[Means for Solving the Problem]A connector of the present disclosure is provided with a connector housing to be fixed to an electrically conductive casing of a device, a terminal to be held in the connector housing, a wire to be electrically connected to the wire and to be drawn out from inside the connector housing along a first direction to the outside, and an electrically conductive shielding shell, the wire being a shielded wire including a core wire, a first insulating coating covering an outer periphery of the core wire, an electrically conductive electromagnetic shielding member covering an outer periphery of the first insulating coating, and a second insulating coating covering an outer periphery of the electromagnetic shielding member, the connector housing including an outer arrangement portion to be arranged outside the casing and an inner arrangement portion to be arranged inside the casing, wherein the shield shell comprises a first part to be disposed within the outer arrangement portion and a second part disposed at a position offset from the first part in a direction opposite to the first direction, wherein the first part comprises a first shield connection portion to be electrically connected to the electromagnetic shielding member, wherein the first part covers an outer periphery of a part of the wire to be disposed within the outer arrangement portion, wherein the second part comprises a second shield connection portion to be electrically connected to the casing and fixed within the casing, and wherein the second shield connection portion is located within an outer periphery of the connector housing as viewed from the first direction.A connector fixing structure of the present disclosure is provided with an electrically conductive casing of a device, a connector housing for holding a terminal and a wire electrically connected to the terminal and pulled out along a first direction, and an electrically conductive shielding casing, the casing including a mounting hole, the terminal being inserted through the mounting hole, and a shielding casing connecting portion provided inside the casing, the connector housing including an outer arrangement portion to be arranged outside the casing and an inner arrangement portion to be arranged inside the casing, the outer arrangement portion including a fixing portion to be fixed to an outer surface of the casing, the wire being a shielded wire that includes a core wire, a first insulating coating that covers an outer periphery of the core wire, an electrically conductive wire, An electromagnetic shielding member covering an outer periphery of the first insulating coating and a second insulating coating covering an outer periphery of the electromagnetic shielding member, wherein the shielding shell comprises a first part to be disposed within the outer arrangement portion and a second part to be disposed within the casing together with the inner arrangement portion, wherein the first part comprises a first shielding connection portion to be electrically connected to the electromagnetic shielding member, wherein the first part covers an outer periphery of a part of the wire to be disposed within the outer arrangement portion, wherein the second part comprises a second shielding connection portion, and the second shielding connection portion is located within an outer periphery of the connector as viewed from the first direction, wherein the second shielding connection portion is electrically connected to the shielding shell connection portion within the casing and fixed.[Effect of the Invention]According to the connector and the connector fixing structure of the present disclosure, a decrease in electromagnetic shielding performance can be prevented.[Brief Description of Drawings]FIG. 1 is a cross-sectional view of a connector in a state fixed to a bezel in an embodiment, FIG. 2 is an exploded perspective view of the connector shown in FIG. 1 , FIG. 3 is a plan view of the connector shown in FIG. 1, as viewed from a fixing surface on the bezel, FIG. 4 is a perspective view showing a third housing, a terminal, a shield shell, and a wire provided in the connector shown in FIG. 1 , FIG. 5 is a cross-sectional view showing a part of the connector shown in FIG. 1 enlarged; and FIG. 6 is a cross-sectional view showing a part of the connector shown in FIG. 1 in an enlarged manner.[Embodiments of the Invention][Description of Embodiments of the Present Disclosure]First, embodiments of the present disclosure will be listed and described.[1] The connector of the present disclosure is provided with a connector housing to be fixed to an electrically conductive casing of a device, a terminal to be held in the connector housing, a wire to be electrically connected to the wire and to be drawn out from inside the connector housing along a first direction to the outside, and an electrically conductive shielding shell, the wire being a shielded wire including a core wire, a first insulating coating covering an outer periphery of the core wire, an electrically conductive electromagnetic shielding member covering an outer periphery of the first insulating coating, and a second insulating coating covering an outer periphery of the electromagnetic shielding member, the connector housing including an outer arrangement portion to be arranged outside the casing and an inner arrangement portion to be arranged inside the casing, wherein the shield shell includes a first part to be disposed within the outer arrangement portion and a second part disposed at a position offset from the first part in a direction opposite to the first direction, the first part includes a first shield connection portion to be electrically connected to the electromagnetic shielding member, the first part covers an outer periphery of a part of the wire to be disposed within the outer arrangement portion, the second part includes a second shield connection portion to be electrically connected to the casing and fixed within the casing, and the second shield connection portion is located within an outer periphery of the connector housing as viewed from the first direction.According to this configuration, an electrically connected part of the shield shell and the bezel may be disposed inside the bezel. Further, the first part to be disposed inside the outer arrangement portion includes the first shield connection portion to be electrically connected to the electromagnetic shielding member. That is, an electrically connected part of the shield shell and the electromagnetic shield member is disposed inside the connector housing. According to these, the electrically connected part of the shield shell and the bezel and the electrically connected part of the shield shell and the electromagnetic shielding member can be prevented from being humidified. Therefore, it is possible to prevent a decrease in electromagnetic shielding performance due to adhesion of water to the electrically connected part of the shielding shell and the casing and the electrically connected part of the shielding shell and the electromagnetic shielding member.Further, the second shield connection portion is located inside the outer periphery of the connector housing as viewed from the first direction. Thus, the second shield connection portion is fixed to the bezel at a position near the wire compared to the case where the second shield connection portion is located outside the outer edge of the connector housing when viewed from the first direction. Therefore, the vibration of the connector with respect to the bezel is easily suppressed when the wire vibrates when the second shield connection portion is fixed to the bezel.[2] In paragraph [1] described above, the second shield connecting portion includes a first through hole, and a bolt for fixing the bezel and the second shield connecting portion is passed through the first through hole.According to this configuration, the second shield connection portion can be easily fixed to the bezel by the bolt and the nut to be fastened to the bolt. Further, since the second shield connection portion is integrated with the bezel, when the second shield connection portion is fixed to the bezel by the bolt and the nut, relative movement of the second shield connection portion with respect to the bezel can be suppressed. Therefore, the vibration of the connector with respect to the bezel can be more suppressed.[3] In paragraph [2] described above, the terminal includes a second through hole, a terminal fixing screw for fixing a mating terminal disposed inside the casing and the terminal is passed through the second through hole, the first through hole penetrating the second shield connection portion in a second direction orthogonal to the first direction, and the second through hole penetrating the terminal in the second direction.According to this configuration, the direction in which the terminal fixing screw is passed through the terminal and the mating terminal to connect the terminal and the mating terminal and the direction in which the screw for fixing the second shield connection portion to the bezel is passed through the bezel and the second shield connection portion may be the same. Therefore, the operability of connection of the second shield connection portion and the casing and that of the terminal and the mating terminal can be improved.[4] In paragraph [2] or [3] described above, the shield shell includes a nut fixed in the first through hole and to be fastened to the bolt.According to this configuration, the second shield connection portion can be easily fixed to the bezel by inserting the bolt for fixing the second shield connection portion to the bezel into the nut fixed in the first through hole.[5] The connector fixing structure of the present disclosure is provided with an electrically conductive casing of a device, a connector housing for holding a terminal and a wire electrically connected to the terminal and pulled out along a first direction, and an electrically conductive shielding shell, the casing including a mounting hole, the terminal being inserted through the mounting hole, and a shielding shell connecting portion provided inside the casing, the connector housing including an outer arrangement portion to be arranged outside the casing and an inner arrangement portion to be arranged inside the casing, the outer arrangement portion including a fixing portion to be fixed to an outer surface of the casing, the wire being a shielded wire including a core wire, a first insulating coating covering an outer periphery of the core wire, an electrically conductive wire, An electromagnetic shielding member covering an outer periphery of the first insulating coating and a second insulating coating covering an outer periphery of the electromagnetic shielding member, wherein the shielding shell comprises a first part to be disposed within the outer arrangement portion and a second part to be disposed within the casing together with the inner arrangement portion, wherein the first part comprises a first shielding connection portion to be electrically connected to the electromagnetic shielding member, wherein the first part covers an outer periphery of a part of the wire to be disposed within the outer arrangement portion, wherein the second part comprises a second shielding connection portion, and wherein the second shielding connection portion is located within an outer periphery of the connector as viewed from the first direction, wherein the second shielding connection portion is electrically connected to the shielding shell connection portion within the casing and fixed.According to this configuration, functions and effects similar to those of paragraph [1] described above can be obtained.[Details of Embodiment of Present Disclosure]Specific examples of a connector and a connector fixing structure of the present disclosure will be described below with reference to the drawings. For convenience of description, some components may be shown in exaggerated or simplified form in each drawing. Further, a dimensional ratio of each part in each figure may be different. In each figure, the X, Y, and Z axes are shown orthogonal to each other.

The fixing portion 33 has, for example, an annular shape surrounding the tubular portion 32. The fixing portion 33 has a facing surface 34 facing the outer surface of the bezel 11. For example, the facing surface 34 is an end surface in the direction opposite to the first direction D 1 among both end surfaces of the fixing portion 33 in the first direction D 1. For example, the facing surface 34 is a flat surface perpendicular to the first direction D 1.As shown in FIGS. 1 and 3, the fixing portion 33 may include a seal groove 35 recessed from the facing surface 34 in the first direction D 1. The seal groove 35 has an annular shape surrounding the tubular portion 32 as viewed from the first direction D 1. The connector 20 may include a first sealing member 36 to be disposed in the sealing groove 35. The first sealing member 36 is, for example, a rubber ring.The fixing portion 33 includes, for example, four fixing holes 37. Note that the number of the fixing holes 37 of the fixing portion 33 is not limited to four, but may be any plurality. Each fixing hole 37 penetrates the fixing portion 33 in the first direction D 1. Each fixing hole 37 is located outside the seal groove 35 as viewed from the first direction D 1. Further, a plurality of the fixing holes 37 are separated by an equal distance along an outer edge 31A of the fixing portion 33, for example, as viewed from the first direction D 1. An annular ring 38 made of metal may be mounted on the inner circumferential surface of each fixing hole 37.The first housing 31 is fixed to an outer peripheral part of the mounting hole 14 in the body portion 12 of the bezel 11. The first housing 31 is disposed on the casing 11 such that the mounting hole 14 is disposed inside the tubular portion 32 as viewed from the first direction D 1. Further, the first housing 31 is disposed on the bezel 11 with the facing surface 34 facing the outer surface of the body portion 12. The first housing 31 is fixed to the body portion 12 by unillustrated screws inserted through the respective fixing holes 37. Note that the first sealing member 36 seals between the outer surface of the bezel 11 and the fixing portion 33 by being held in close contact with the inner surface of the sealing groove 35 and the outer surface of the bezel 11. That is, the first sealing member 36 prevents water from entering the inside of the bezel 11 or the inside of the connector 20 through a gap between the outer surface of the bezel 11 and the fixing portion 33.As shown in FIGS. 1 and 2, the second housing 41 includes, for example, a tubular second housing body 42 extending along the first direction D 1 and an outer fitting portion 43 integrally provided on the outer circumferential surface of the second housing body 42.

The second cover portion 111 includes, for example, a second connection portion 112 in an end region in the first direction D 1. Note that, for example, the first and second connection portions 102, 112 correspond to a "first shield connection portion". Each of the first and second connection portions 102, 112 has a semicircular shape, for example, as viewed from the first direction D 1. The first connecting portion 102 covers the outer circumferential surface of the first wire holding portion 65. The second connecting portion 112 covers the outer circumferential surface of the second wire holding portion 67. Further, the first and second connecting portions 102, 112 cover the outer circumferential surface of the folded portion 83 a. The inner surface of each of the first and second connection portions 102, 112 is in contact with the outer circumferential surface of the folded portion 83 a. The first and second connecting portions 102, 112 also cover the outer periphery of a part of the wire 23 that is disposed outside the bezel 11 and is not covered by the electromagnetic shielding member 83 when the connector 20 is fixed to the bezel 11. The first and second connection portions 102, 112 are disposed within the second housing body 42.The first and second cover portions 101, 111 are fixed to the wire 23 by a second fixing member 121. The second fixing member 121 is located between the wire through hole 71 and the through hole 45 inside the second case body 42 in the first direction D 1. Specifically, the second fixing member 121 is located between the wire through hole 71 and the third sealing member 85. the second fixing member 121 is mounted at a position on the outer periphery of the first and second connection portions 102, 112 to wedge the first connection portion 102, the second connection portion 112, and the folded portion 83 abetween the first fixing member 89 and the second fixing member 12. The second fixation member 121 is, for example, a metal crimp ring. The second fixing member 121 pulls each of the first and second connection portions 102, 112 and the wire 23 tightly so that the folded portion 83 ais held in close contact with each of the first and second connection portions 102, 112. Thereby, the electromagnetic shielding member 83 and each of the first and second cover portions 101, 111 are electrically connected.For example, as shown in FIGS. 1 and 4, the second cover portion 111 includes a second shield connection portion 113 at a position offset from the second connection portion 112 in the direction opposite to the first direction D 1. For example, the second shield connection portion 113 is coupled to the second connection portion 112 by a coupling / covering portion 114 extending in the second direction D 2 from an end part of the second connection portion 112 in the direction opposite to the first direction D 1. The coupling / covering portion 114 covers an end surface in the first direction D 1 of the second terminal holding portion 66. The second shield connection portion 113 is in the form of a flat plate orthogonal to the second direction D 2, for example. When viewed from the direction opposite to the second direction D 2, the second shield connection portion 113 covers, for example, a part of the third housing 61 between the second terminal exposure opening 69 and the second wire holding portion 67.As shown in FIG. 1, an end portion of the second shield connection portion 113 in the direction opposite to the first direction D 1 protrudes from the second housing 41 in the direction opposite to the first direction D 1. An end portion of the second shield connection portion 113 in the first direction D 1 is located at a position overlapping the exposure recess 51 of the second housing 41 in the second direction D 2. Thus, an end surface of the second shield connection portion 113 in the second direction D 2 is entirely exposed to the outside of the connector housing 21.As shown in FIG. 3, in the connector 20, the second shield connection portion 113 is located inside an outer edge 21A of the connector housing 21 as viewed from the first direction D 1. for example, the second shield connection portion 113 is located inside an outer edge 31A of the fixing portion 33 of the first housing 31 as viewed from the first direction D 1. further, the second shield connection portion 113 is located inside an outer edge 41A of the second housing 41 as viewed from the first direction D 1.As shown in FIGS. 1 and 4, the second shield connecting portion 113 includes a first through hole 115 through which a bolt 122 for fixing the shield shell connecting portion 13 of the bezel 11 and the second shield connecting portion 113 is passed. For example, the first through hole 115 penetrates the second shield connecting portion 113 in the second direction D 2. For example, the first through hole 115 is located at a position offset from the second through hole 25 in the first direction D 1. Further, the first through hole 115 is disposed adjacent to the second through hole 25 in the first direction D 1, for example, as viewed from the second direction D 2.As shown in FIG. 6, the shield shell 24 includes a nut 123 fixed in the first through hole 115 and to be fastened to the bolt 122. The nut 123 is located between the second shield connection portion 113 and the second terminal holding portion 66, for example, in the second direction D 2. For example, the nut 123 is fixed by press-fitting into the first through hole 115 in the first through hole 115.Next, a procedure of fixing the connector 20 to the bezel 11 will be described.As shown in FIG. 1, the first housing 31 is first fixed to the outer peripheral part of the mounting hole 14 in the body portion 12 of the bezel 11. Thereafter, the second and third housings 41, 61 fixed to each other are mounted in the first housing 31. Note that components such as the wire 23 and the terminal 22, other than the first housing 31, the first sealing members 36, and the rims in the connector 20, are previously mounted in the second and third housings 41, 61. When the second and third housings 41, 61 are assembled into the first housing 31, the first terminal holding portion 64, the second terminal holding portion 66, the terminal 22, and the second shield connecting portion 113 are inserted into the casing 11 through the tubular portion 32 and the assembly hole 14. Then, the second shield connection portion 113 is disposed at a position overlapping the shield shell connection portion 13 in the second direction D 2 inside the casing 11.Thereafter, the bolt 122 is inserted into the through hole 15 and the first through hole 115 in the direction opposite to the second direction D 2 and tightened into the nut 123. At this time, a tool for tightening the bolt 122 and the nut 123 is inserted into the casing 11 through an opening provided in a position different from the mounting opening 14 in the casing 11, for example. By tightening the nut 123 and the bolt 122, the second shield connection portion 113 is electrically connected and fixed to the shield shell connection portion 13 inside the casing 11. When the second shield connecting portion 113 is fixed to the shield shell connecting portion 13, the fixing of the connector 20 to the bezel 11 is completed.Note that the terminal 22 and the mating terminal 201 may be connected before the second shield connection portion 113 and the shield shell connection portion 13 are connected, or may be connected after the second shield connection portion 113 and the shield shell connection portion 13 are connected. The terminal 22 and the mating terminal 201 are electrically connected and fixed to each other by the terminal fixing bolt 202 passing through the second through hole 25, and the mating terminal 201 and the nut 203 are to be fastened to the terminal fixing bolt 202. For example, the terminal fixing screw 202 is inserted into the second through hole 25 in the direction opposite to the second direction D 2, similarly to the screw 122. Note that the terminal fixing screw 202 can be passed through the fitting terminal 201 and the terminal 22 in the second direction D 2. Further, a tool for fastening the terminal fixing bolt 202 and the nut 203 is inserted into the casing 11 through, for example, an opening provided at a position different from the mounting hole 14 in the casing 11, similarly to the tool for fastening the bolt 122 and the nut 123.A boundary B 1 between an outer region A 1 outside the bezel 11 and an inner region A 2 inside the bezel 11 is shown by a one-dot chain line in FIG. 1. For example, the boundary B 1 is located on the outer surface of the bezel 11. the connector housing 21 includes an outer arrangement portion 21X to be arranged outside the bezel 11 and an inner arrangement portion 21Y to be arranged inside the bezel 11. That is, the connector housing 21 includes the outer arrangement portion 21X to be arranged in the outer region A 1 and the inner arrangement portion 21Y to be arranged in the inner region A 2. In FIG. 1, the outer arrangement portion 21X is a part arranged in a region of the connector housing 21 that is offset from the boundary B 1 in the first direction D 1. The inner arrangement portion 21Y is a part arranged in a region of the connector housing 21 that is offset from the boundary B 1 in the direction opposite to the first direction D 1.For example, the first housing 31 is contained in the outer arrangement portion 21X. Thus, the outer arrangement portion 21X includes the fixing portion 33 to be fixed to the outer surface of the bezel 11.Further, the shield shell 24 includes a first part 24X to be disposed inside the outer arrangement portion 21X and a second part 24Y disposed at a position offset from the first part 24X in the direction opposite to the first direction D 1. The first part 24X is a part to be disposed in the outer region A 1 in the shield shell 24. The second part 24Y is a part to be disposed in the inner region A 2 in the shield shell 24. The first part 24X includes the first and second connection portions 102, 112 to be electrically connected to the electromagnetic shielding member 83, and covers the outer periphery of a part of the wire 23 to be disposed inside the outer arrangement portion 21X. Further, the second part 24Y includes the second shield connection portion 113 to be electrically connected and fixed to the bezel 11 inside the bezel 11.The functions and effects of this embodiment will be described.(1) The connector 20 is provided with the connector housing 21 to be fixed to the electrically conductive bezel 11 of the device 10 and the terminal 22 to be held in the connector housing 21. Further, the connector 20 is provided with the wire 23 to be electrically connected to the terminal 22 and to be drawn out from the inside of the connector housing 21 to the outside along the first direction D 1 and the electrically conductive shielding shell 24. The wire 23 is the shielded wire including the core wire 81, the first insulating coating 82 covering the outer periphery of the core wire 81, the electrically conductive electromagnetic shielding member 83 covering the outer periphery of the first insulating coating 82, and the second insulating coating 84 covering the outer periphery of the electromagnetic shielding member 83. The connector housing 21 includes the outer arrangement portion 21X to be arranged outside the bezel 11 and the inner arrangement portion 21Y to be arranged inside the bezel 11. The shield shell 24 closes the first part 24X to be disposed inside the outer arrangement portion 21X and the second part 24Y to be disposed at the position offset from the first part 24X in the direction opposite to the first direction D 1. The first part 24X includes the first and second connection portions 102, 112 to be electrically connected to the electromagnetic shielding member 83, and covers the outer periphery of the part of the wire 23 to be disposed inside the outer arrangement portion 21X. The second part 24Y includes the second shield connection portion 113 to be electrically connected and fixed to the bezel 11 inside the bezel 11. The second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 as viewed from the first direction D 1.According to this configuration, the electrically connected part of the shield shell 24 and the bezel 11 may be disposed inside the bezel 11. In this embodiment, the electrically connected part of the shield shell 24 and the bezel 11 is a part that is in contact with the shield shell connection portion 13 and the second shield connection portion 113. Further, the first part 24X to be disposed inside the outer arrangement portion 21X includes the first and second connection portions 102, 112 to be electrically connected to the electromagnetic shielding member 83. That is, an electrically connected part of the shield shell 24 and the electromagnetic shield member 83 is disposed inside the connector housing 21. In this embodiment, the electrically connected part of the shield shell 24 and the electromagnetic shielding member 83 is a part where each of the first and second connection portions 102, 112 and the electromagnetic shielding member 83 are in contact. From these, the electrically connected part of the shield shell 24 and the bezel 11 and the electrically connected part of the shield shell 24 and the electromagnetic shielding member 83 can be prevented from being humidified. Therefore, it is possible to prevent a decrease in electromagnetic shielding performance due to adhesion of water to the electrically connected part of the shielding shell 24 and the casing 11 and the electrically connected part of the shielding shell 24 and the electromagnetic shielding member 83.Further, the second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 as viewed from the first direction D 1. Thus, the second shield connection portion 113 is fixed to the bezel 11 at a position near the wire 23 as compared to the case where the second shield connection portion 113 is located outside the outer edge 21A of the connector housing 21 as viewed from the first direction D 1. Therefore, the vibration of the connector 20 with respect to the bezel 11 is easily suppressed when the wire 23 vibrates when the second shield connection portion 113 is fixed to the bezel 11.Further, a diameter of a wire 23 generally increases when the wire 23 is a high voltage wire compatible with high voltages and large currents. As the diameter of the wire 23 increases, the connector 20 is easily affected by the vibration of the wire 23 when the wire 23 vibrates. In the connector 20 of this embodiment, even when such a wire 23 is provided, the vibration of the connector 20 due to the vibration of the wire 23 is easily suppressed because the second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 as viewed from the first direction D 1.(2) The second shield connecting portion 113 includes the first through hole 115 through which the bolt 122 for fixing the bezel 11 and the second shield connecting portion 113 is passed. According to this configuration, the second shield connection portion 113 can be easily fixed to the bezel 11 by the bolt 122 and the nut 123 to be fastened to the bolt 122. Further, relative movement of the second shield connection portion 113 with respect to the bezel 11 can be suppressed because the second shield connection portion 113 is integrated with the bezel 11 when the second shield connection portion 113 is fixed to the bezel 11 by the bolt 112 and the nut 123. Therefore, the vibration of the connector 20 with respect to the bezel 11 can be more suppressed.(3) The terminal 22 includes the second through hole 25 through which the terminal fixing screw 202 for fixing the fitting terminal 201 disposed inside the casing 11 and the terminal 22 is passed. The first through hole 115 penetrates the second shield connection portion 113 in the second direction D 2 orthogonal to the first direction D 1. The second through hole 25 penetrates the terminal 22 in the second direction D 2.According to this configuration, the direction in which the terminal fixing screw 202 is passed through the terminal 22 and the mating terminal 201 to connect the terminal 22 and the mating terminal 201 and the direction in which the screw 122 for fixing the second shield connection portion 113 to the bezel 11 is passed through the bezel 11 and the second shield connection portion 113 may be the same. Therefore, the operability of connecting the second shield connecting portion 113 and the casing 11 and that of the terminal 22 and the mating terminal 201 can be improved.(4) The shield shell 24 includes the nut 123 fixed in the first through hole 115 and to be fastened to the bolt 122. According to this configuration, the second shield connection portion 113 can be easily fixed to the bezel 11 by inserting the bolt 122 for fixing the second shield connection portion 113 to the bezel 11 into the nut 123 fixed in the first through hole 115.(5) The fixing structure of the connector 20 is provided with the electrically conductive enclosure 11 of the device 10. Further, the fixing structure of the connector 20 is provided with the connector housing 21 for holding the terminal 22 and the wire 23 electrically connected to the terminal 22 and pulled out along the first direction D 1 and the electrically conductive shielding shell 24. The bezel 11 includes the mounting hole 14 through which the terminal 22 is inserted and the shield shell connecting portion 13 provided inside the bezel 11. The connector housing 21 includes the outer arrangement portion 21X to be arranged outside the bezel 11 and the inner arrangement portion 21Y to be arranged inside the bezel 11. The outer arrangement portion 21X includes the fixing portion 33 to be fixed to the outer surface of the bezel 11. The wire 23 is the shielded wire including the core wire 81, the first insulating coating 82 including the outer periphery of the core wire 81, the electrically conductive electromagnetic shielding member 83 covering the outer periphery of the first insulating coating 82, and the second insulating coating 84 covering the outer periphery of the electromagnetic shielding member 83. The shield shell 24 includes the first part 24X to be disposed inside the outer arrangement portion 21X and the second part 24Y to be disposed inside the casing 11 together with the inner arrangement portion 21Y. The first part 24X includes the first and second connection portions 102, 112 to be electrically connected to the electromagnetic shielding member 83, and covers the outer periphery of the part of the wire 23 to be disposed inside the outer arrangement portion 21X. The second part 24Y includes the second shield connection portion 113. The second shield connection portion 113 is located inside the outer edge 21A of the connector housing 21 as viewed from the first direction D 1, and is electrically connected and fixed to the shield shell connection portion 13 inside the casing 11. According to this configuration, functions and effects similar to those of paragraph (1) described above can be obtained.(6) In order to prevent an electrically connected part of a shield shell and a casing and an electrically connected part of the shield shell and an electromagnetic shielding member from being wetted, it is provided to provide a connector with a cover for completely covering the outer surface of a connector housing fixed to the casing. In this case, however, the connector is enlarged. On the other hand, in this embodiment, the electrically connected part of the shield shell 24 and the bezel 11 is disposed inside the bezel 11, and the electrically connected part of the shield shell 24 and the electromagnetic shielding member 83 is disposed inside the connector housing 21. Therefore, as compared with the case where the connector is provided with the cover, the electrically connected part of the shield shell 24 and the bezel 11 and the electrically connected part of the shield shell 24 and the electromagnetic shielding member 83 can be prevented from being humidified while preventing the connector 20 from being enlarged. Further, an increase in the number of components can be prevented because the connector 20 does not need to be provided with a cover as a component.This embodiment may be modified and implemented as follows. This embodiment and the following modifications can be carried out in combination without being distinguished from each other from a technical point of view.The nut 123 may not be fixed by press-fitting in the first through hole 115. The nut 123 may be fixed to the shield shell 24 by, for example, bonding or welding. Further, the nut 123 can be held by the connector housing 21. Further, the nut 123 may be separately prepared from the shield shell 24 and the connector housing 21. In this case, when the connector 20 is fixed to the bezel 11, the nut 123 is fastened to the bolt 122 passing through the shield shell connecting portion 13 and the second shield connecting portion 113.In the previous embodiment, the connector 20 is provided with the nut 123 for fixing the shield shell connection portion 13 and the second shield connection portion 113. However, the connector 20 may be provided with the bolt 122 for fixing the shield shell connection portion 13 and the second shield connection portion 113.The second through hole 25 may penetrate the terminal 22 in a direction different from the second direction D 2. Further, the first through hole 115 may penetrate the second shield connection portion 113 in a direction different from the second direction D 2. Further, the first and second through holes 115, 25 may penetrate in mutually different directions.The second shield connecting portion 113 and the shield shell connecting portion 13 may be fixed by a method other than the screw fastening using the screw 122 and the nut 123. For example, the second shield connection portion 113 and the shield shell connection portion 13 may be fixed by a bracket for sandwiching the second shield connection portion 113 and the shield shell connection portion 13. Further, for example, the shield shell connecting portion 13 may have a clamp shape for sandwiching the second shield connecting portion 113 or a female terminal shape into which the second shield connecting portion 113 is fitted. Further, for example, the second shield connection portion 113 and the shield shell connection portion 13 may be fixed by welding or crimping. In these cases, the second shield connection portion 113 may not include the first through hole 115. Further, the shield shell connecting portion 13 may not include the through hole 15. The method of fixing the terminal 22 and the mating terminal 201 may also be similarly changed.The shape and configuration of the connector housing 21 are not limited to those of the previous embodiment when the connector housing 21 includes the outer arrangement portion 21X to be arranged outside the bezel 11 and the inner arrangement portion 21Y to be arranged inside the bezel 11. For example, the first and second housings 31, 41 may form an integrally molded product.The shape and configuration of the shield shell 24 are not limited to those of the previous embodiment when the shield shell 24 includes the first part 24X to be disposed inside the outer arrangement portion 21X and the second part 24Y disposed at the position offset from the first part 24X in the direction opposite to the first direction D 1. For example, the first and second cover portions 101, 111 may be integrally formed. Further, for example, the shield shell 24 may be composed of a plurality of components divided into a plurality of parts in the first direction D 1.The number of the terminal 22 provided in the connector 20 is not limited to one, and a plurality of terminals 22 may be provided. In this case, the plurality of terminals 22 are arranged side by side along a direction orthogonal to the first direction D 1. A wire 23 is electrically connected to each of the terminals 22.The direction opposite to the second direction D 2 in the previous embodiment may be defined as the second direction D 2. The direction opposite to the third direction D 3 in the previous embodiment may be defined as the third direction D 3.The embodiment disclosed herein should be considered illustrative in all aspects and not restrictive. The scope of the present invention is represented not by the above meaning but by the claims, and is intended to include all changes with the scope of the claims and the meaning and scope of equivalents.[List of Reference Numerals]10 Device 11 Bezel 12 Body portion 13 Shield shell connecting portion 14 Mounting opening 15 Through hole 20 Connector 21 Connector housing 21A Outer rim 21X Outer arrangement portion 21Y Inner arrangement portion 22 Terminal 23 Wire 24 Shield shell 24X First part 24Y Second part 25 Second through hole 31 First housing 31A Outer rim 32 Tubular portion 33 Fixing portion 34 Facing surface 35 Sealing groove 36 First sealing member 37 Fixing hole 38 Rim 41 Second housing 41A Outer rim 42 Second housing body 42 aFirst end 42 bSecond end 43 Outer adjustment portion 44 Protrusion opening 45 Through hole 47 Bottom wall 48 Adjustment portion 49 Second sealing member 51 Exposure recess 52 First engagement portion 53 Engagement hole 61 Third housing 62 First divided housing 63 Second divided housing 64 First Terminal holding portion 65 First wire holding portion 66 Second terminal holding portion 67 Second wire holding portion 68 First terminal exposure opening 69 Second terminal exposure opening 71 Wire through opening 72 Second engagement portion 81 Core wire 82 First insulating coating 83 Electromagnetic shielding member 83 a Gefaltet portion 84 Second insulating coating 85 Third sealing member 86 Rear bracket 87 a, 87 bparted bracket 88 fixing member 89 first fixing member 101 first cover portion 102 first connection portion (first shield connection portion) 111 second cover portion 112 second connection portion (first shield connection portion) 113 second shield connection portion 114 coupling / cover portion 115 first through hole 122 bolt 123 nut 121 second fixing member 201 mating terminal 202 terminal fixing bolt 203 nut A 1 outer region A 2 inner region B 1 boundary D 1 first direction D 2 second direction D 3 third directionReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
