[0003] Patent Document 1: Japanese Patent Application Publication No. 2017-22264 Summary of the Invention The problem that the invention aims to solve
[0004] In the electromagnetic shielding cover described above, the bending fixing portion folds back from the electromagnetic shielding cover toward the side where the electromagnetic shielding member is led out. Therefore, an opening is formed in the electromagnetic shielding cover along with the forming of the bending fixing portion. Consequently, in the electromagnetic shielding cover covering the first connector, if the positions of the bending fixing portion and the opening are not adequately considered, the electromagnetic shielding effect of the electromagnetic shielding cover may not be sufficiently obtained.
[0005] Therefore, the purpose is to provide a connector unit that can suppress the reduction of the electromagnetic shielding effect of the electromagnetic shielding cover and can fix the electromagnetic shielding component. Solution for solving the problem
[0006] The connector unit disclosed herein includes: a first connector; a second connector; a plurality of wires electrically connecting the first connector and the second connector; an electromagnetic shielding cover fixed to the first connector to cover the first connector; an electromagnetic shielding member formed of a conductor in a sheet shape and disposed on the side of the plurality of wires; and a bracket formed of a conductor. The electromagnetic shielding cover has a cover body and a fixing plate fixed to the cover body. One end of the electromagnetic shielding member is integrated with the first connector by being clamped by the cover body and the fixing plate. The bracket is fixed to the other end of the electromagnetic shielding member and is detached from the second connector and is not integrated with the second connector. Invention Effects
[0007] According to this disclosure, a connector unit can be provided that can suppress the reduction of the electromagnetic shielding effect of the electromagnetic shielding cover and can fix the electromagnetic shielding component. Attached Figure Description

[0009] [Description of embodiments of this disclosure] The embodiments of this disclosure are first described by listing them. The connector unit disclosed herein, [1] The device comprises: a first connector; a second connector; multiple wires electrically connecting the first connector and the second connector; an electromagnetic shielding cover fixed to the first connector to cover the first connector; an electromagnetic shielding member formed of a conductor in a sheet shape and disposed on the side of the multiple wires; and a bracket formed of a conductor, the electromagnetic shielding cover having a cover body and a fixing plate fixed to the cover body, one end of the electromagnetic shielding member being integrated with the first connector by being clamped by the cover body and the fixing plate, the bracket being fixed to the other end of the electromagnetic shielding member, and the bracket being detached from the second connector and not integrated with the second connector.
[0010] According to this structure, one end of the electromagnetic shielding member is clamped and fixed by the cover body and the fixing plate. This suppresses the reduction of the electromagnetic shielding effect of the electromagnetic shielding cover and fixes the electromagnetic shielding member to the cover. Furthermore, because the bracket is detached from the second connector, it can be assembled into, for example, a vehicle-mounted machine's housing for grounding.
[0011] [2] The second connector includes: a terminal for connecting to the wire; a retaining member made of synthetic resin for retaining the terminal; and a terminal block made of synthetic resin for mounting on a vehicle. According to this structure, compared to cases where the terminal block is made of metal, the connector unit can be made lighter. Furthermore, by separating the bracket from the second connector, it avoids becoming a structure where the bracket is grounded via the terminal block of the second connector. Therefore, the terminal block does not need to be made of conductor, increasing the freedom in selecting the material for the terminal block.
[0012] [3] The electromagnetic shielding member only covers one side of the plurality of wires in a direction perpendicular to the direction in which the plurality of wires are arranged. According to this structure, the increase in the number of electromagnetic shielding members used in the connector unit can be suppressed.
[0013] [4] The cover body and the fixing plate are respectively plate-shaped and overlap each other in the thickness direction. The cover body has a positioning hole for positioning. The positioning hole passes through the cover body in the thickness direction. The fixing plate has a notch at the end of the fixing plate. The width of the positioning hole and the width of the notch are equal. Viewed from the thickness direction of the fixing plate, the entire or part of the positioning hole and part of the electromagnetic shielding component are located in the area of the notch.
[0014] According to this structure, during the assembly of the electromagnetic shielding cover and electromagnetic shielding component, the positioning hole of the cover body and the notch of the fixing plate are overlapped, thereby enabling the fixing plate to be positioned relative to the cover body. Furthermore, when the electromagnetic shielding component is sandwiched between the cover body and the fixing plate, the edge of the electromagnetic shielding component can be visually confirmed via the notch to be near the end of the fixing plate where the notch is located. Therefore, the alignment of the electromagnetic shielding component can be performed while viewing it through the notch. Thus, the alignment of the electromagnetic shielding component becomes easier. As a result, the workability of fixing the electromagnetic shielding cover and the electromagnetic shielding component together is improved.
[0015] [Details of the embodiments of this disclosure] Specific examples of the connector unit of this disclosure are described below with reference to the accompanying drawings. In the drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. Furthermore, the dimensional ratios of the various parts sometimes differ in the drawings. Additionally, the term "orthogonal" in this specification includes not only strictly orthogonal cases but also cases that are substantially perpendicular to the extent that they serve the function and effect of this embodiment.
[0016] Furthermore, the term "flat plate" in this specification also includes shapes with chamfered corners or edges, shapes with rounded corners or edges, and shapes with uneven surfaces forming part or all of the surfaces constituting the shape. Additionally, the term "cylindrical" as used in this specification includes not only cylindrical shapes with a continuous circumferential wall, but also shapes formed by combining multiple components, and shapes such as a C-shape with a notch in a portion of the circumference. Furthermore, "cylindrical" shapes include circles, ellipses, and polygons with pointed or rounded corners.
[0017] (Structure of connector unit 10) like Figure 1 and Figure 2 As shown, the connector unit 10 of this embodiment includes a first connector 11, a second connector 12, a plurality of wires 13 that electrically connect the first connector 11 and the second connector 12, and a shielding unit 14.
[0018] like Figure 1 As shown, the first connector 11 has a plurality of first terminals 21. The second connector 12 has a plurality of second terminals 31. One end of each wire 13 is connected to each first terminal 21. The other end of each wire 13 is connected to each second terminal 31. The first connector 11 and the second connector 12 are, for example, connectors for high voltage.
[0019] like Figure 2 As shown, the first connector 11 is assembled to the first vehicle-mounted unit M1. The first vehicle-mounted unit M1 is, for example, an inverter. A plurality of first terminals 21 are respectively connected to a plurality of terminals (not shown) disposed on the first vehicle-mounted unit M1. The second connector 12 is assembled to the second vehicle-mounted unit M2. The second vehicle-mounted unit M2 is, for example, a drive motor for driving an electric vehicle, hybrid vehicle, etc. Figure 1 The plurality of second terminals 31 shown are respectively connected to a plurality of terminals (not shown) provided on the second vehicle-mounted machine M2.
[0020] (Structure of the first connector 11) The first connector 11 has a plurality of first terminals 21 and a first retaining member 22 for retaining the plurality of first terminals 21.
[0021] like Figure 1 and Figure 2 As shown, the first retaining member 22 includes, for example, a metal base member 23 and a resin member 24 integrally formed with the base member 23. The base member 23 is formed, for example, by stamping a sheet metal. The base member 23 is fixed to the outer side of the housing of the first vehicle-mounted machine M1, for example, using bolts (not shown). The housing of the first vehicle-mounted machine M1 is made of conductor. In addition, the housing of the first vehicle-mounted machine M1 is grounded.
[0022] The resin component 24 is formed by insert molding of a plurality of first terminals 21 as inserts. Each first terminal 21 is embedded in the resin component 24 in such a way that it is partially located inside the resin component 24. In addition, the wire 13 is connected to the first terminal 21 inside the resin component 24.
[0023] Resin component 24 has Figure 1 The opening 25 is shown. Each first terminal 21 can be visually identified from inside the opening 25. The connection operation between the first terminal 21 and the terminal of the first vehicle-mounted machine M1 is performed via the opening 25.
[0024] (Structure of the second connector 12) The second connector 12 includes a plurality of second terminals 31, a second retaining member 32 for retaining the second terminals 31, and a terminal block 33.
[0025] like Figure 1 and Figure 2 As shown, the second retaining member 32 is made of, for example, synthetic resin. The second retaining member 32 is formed by molding a plurality of second terminals 31 as inserts. Furthermore, the wire 13 is connected to the second terminals 31 inside the second retaining member 32. The second retaining member 32 is assembled to the terminal block 33.
[0026] Terminal block 33 is fixed to the outer side of the housing of the second vehicle-mounted machine M2, for example, using bolts (not shown). The housing of the second vehicle-mounted machine M2 is made of conductor. In addition, the housing of the second vehicle-mounted machine M2 is grounded.
[0027] The terminal block 33 is primarily made of synthetic resin, for example. Specifically, the terminal block 33 has a base body 34 made of synthetic resin. A cylindrical collar 35 (not shown) is embedded in the base body 34 for inserting a fixing bolt. The portion of the base body 34, except for the collar 35, is made of synthetic resin. Furthermore, the collar 35 is formed of a material such as metal, which has a higher rigidity than the synthetic resin constituting the main part of the base body 34.
[0028] Terminal block 33 holds a plurality of terminals (not shown). One end of the terminals of terminal block 33 is connected to a second terminal 31. The other end of the terminals of terminal block 33 is connected to a terminal (not shown) provided on the second vehicle-mounted machine M2.
[0029] (Structure of shielding unit 14) The shielding unit 14 includes an electromagnetic shielding member 40, an electromagnetic shielding cover 41 fixed to one end of the electromagnetic shielding member 40, and a bracket 51 fixed to the other end of the electromagnetic shielding member 40. Both the electromagnetic shielding cover 41 and the bracket 51 are composed of free conductors. The electromagnetic shielding cover 41 is integrated with the first connector 11. On the other hand, the bracket 51 is separate from the second connector 12 and is not integrated with it. Furthermore, the bracket 51 is grounded, for example, via the housing of the second vehicle-mounted machine M2. Moreover, the statement "the bracket 51 is not integrated with the second connector 12" means that the bracket 51 is not fixed to any of the components constituting the second connector 12. That is, a structure in which both the second connector 12 and the bracket 51 are fixed to the housing of the second vehicle-mounted machine M2 is a structure in which the bracket 51 is not integrated with the second connector 12.
[0030] (Structure of electromagnetic shielding component 40) The electromagnetic shielding member 40 is made of a conductor and is sheet-shaped. The electromagnetic shielding member 40 is flexible. For example, the electromagnetic shielding member 40 is a braided sheet formed by weaving multiple wires made of conductors into a sheet shape. Furthermore, the forming material of the multiple wires constituting the electromagnetic shielding member 40 can be, for example, copper-based, aluminum-based, or other metallic materials. The electromagnetic shielding member 40 is, for example, a rectangular sheet.
[0031] At least a portion of the electromagnetic shielding member 40 is disposed on the side of the plurality of wires 13. The electromagnetic shielding member 40 only covers one side of the plurality of wires 13 in a direction perpendicular to the direction in which the plurality of wires 13 are arranged. That is, the opposite side of the plurality of wires 13 on which the electromagnetic shielding member 40 is disposed is not covered by the electromagnetic shielding member.
[0032] One end of the electromagnetic shielding member 40 is fixed to the electromagnetic shielding cover 41, and the electromagnetic shielding cover 41 is fixed to the first connector 11. That is, the electromagnetic shielding member 40 is integrated with the first connector 11 via the electromagnetic shielding cover 41.
[0033] (Structure of electromagnetic shielding cover 41) like Figure 3 and Figure 4 As shown, the electromagnetic shielding cover 41 has a cover body 42 and a first fixing plate 43. The cover body 42 covers the first connector 11. The cover body 42 is plate-shaped. The cover body 42 is formed, for example, by stamping a sheet metal.
[0034] The cover body 42 is fixed to the first retaining member 22. The cover body 42 is fixed to the base member 23, for example, using bolts (not shown). The cover body 42 covers the side of the first retaining member 22 opposite to the side facing the first vehicle-mounted machine M1. In addition, the cover body 42 covers the opening 25 of at least the resin member 24 in the first retaining member 22.
[0035] The cover body 42 has a fixing part 44, on which one end of the electromagnetic shielding member 40 is fixed. The fixing part 44 is generally flat. A first fixing plate 43 is fixed to the fixing part 44.
[0036] The first fixing plate 43 is generally flat. The first fixing plate 43 is, for example, made of a metal plate. The first fixing plate 43 is generally rectangular when viewed in the thickness direction.
[0037] The fixing part 44 and the first fixing plate 43 overlap each other in the thickness direction. The end of the electromagnetic shielding member 40 is fixed by being clamped by the fixing part 44 and the first fixing plate 43. Furthermore, the first fixing plate 43 faces the part of the connection between the built-in first terminal 21 and the wire 13 in the first retaining member 22 in its own thickness direction.
[0038] like Figure 4 and Figure 5 As shown, the cover body 42 has a first positioning hole 45 through which the fixing part 44 passes in the thickness direction. The first positioning hole 45 is, for example, generally rectangular when viewed from the thickness direction of the fixing part 44. Multiple first positioning holes 45 are arranged, for example, along a first direction D1 perpendicular to the thickness direction of the fixing part 44. The multiple first positioning holes 45 are arranged, for example, along one long side of a generally rectangular first fixing plate 43. Furthermore, in the following description, a second direction D2 is defined as perpendicular to both the thickness direction of the fixing part 44 and the first direction D1. In this embodiment, the long side of the first fixing plate 43 is along the first direction D1, and the short side of the first fixing plate 43 is along the second direction D2.
[0039] The cover body 42 has a second positioning hole 46 through which the fixing part 44 passes in the thickness direction. The second positioning hole 46 is, for example, generally rectangular when viewed from the thickness direction of the fixing part 44. For example, two second positioning holes 46 are provided. For example, the second positioning holes 46 are provided at positions corresponding to the two ends of the first fixing plate 43 in the first direction D1, that is, the two short sides of the first fixing plate 43.
[0040] like Figure 5 As shown, the first fixing plate 43 has a first notch 47 at one end in the second direction D2. The first notch 47, viewed from the thickness direction of the first fixing plate 43, is a notch recessed from the end of the first fixing plate 43 towards the second direction D2. For example, multiple first notches 47 are arranged along the first direction D1. Each first notch 47, for example, has the same shape and the same size as the others.
[0041] Each of the first notches 47 corresponds to a first positioning hole 45. That is, when the first fixing plate 43 is fixed to the fixing part 44, each of the first notches 47 and each of the first positioning holes 45 are located at the same position in the first direction D1. In addition, in the first direction D1, the width of the first positioning hole 45 and the width of the first notch 47 are formed to be equal to each other.
[0042] The first notch 47 is offset in the second direction D2 relative to the first positioning hole 45. Furthermore, viewed from the thickness direction of the first fixing plate 43, a portion of the first positioning hole 45 and a portion of the electromagnetic shielding member 40 are located within the region of the first notch 47. Within this region, for example, a portion of the first positioning hole 45 and a portion of the electromagnetic shielding member 40 are arranged in the second direction D2.
[0043] The first fixing plate 43 has a second notch 48 at its end in the first direction D1. The second notch 48 is a notch that is recessed from the end of the first fixing plate 43 toward the first direction D1 when viewed from the thickness direction of the first fixing plate 43.
[0044] The second notch 48 overlaps with the second positioning hole 46 in the thickness direction of the fixing part 44 and the first fixing plate 43. Furthermore, in the second direction D2, the width of the second notch 48 and the width of the second positioning hole 46 are equal. Therefore, when assembling the electromagnetic shielding cover 41 and the electromagnetic shielding member 40, by overlapping the second positioning hole 46 and the second notch 48, positioning of the first fixing plate 43 relative to the fixing part 44 in the first direction D1 and the second direction D2 is possible.
[0045] Furthermore, the fixing part 44 and the first fixing plate 43 are fixed to each other, for example, by riveting. For example, the fixing part 44 and the first fixing plate 43 are fixed to each other using a punch (not shown) with an electromagnetic shielding member 40 interposed between them. Multiple stamping portions of the punch are provided along the first direction D1. That is, multiple stamping marks A1 are formed on the fixing part 44 and the first fixing plate 43 along the first direction D1. The stamping marks A1 are recesses formed by the stamping of the punch.
[0046] (Structure of bracket 51) like Figure 3 and Figure 4 As shown, the bracket 51 has a bracket body 52 and a second fixing plate 53. The bracket body 52 is plate-shaped. The bracket body 52 is formed, for example, by stamping a sheet metal.
[0047] A second fixing plate 53 is fixed to the support body 52. The second fixing plate 53 is generally flat. The second fixing plate 53 is made of, for example, a metal plate. The second fixing plate 53 is generally rectangular when viewed in the thickness direction. In this embodiment, the second fixing plate 53 has the same shape and size as the first fixing plate 43. That is, the first fixing plate 43 and the second fixing plate 53 are interchangeable and can be treated as the same component.
[0048] The support body 52 and the second fixing plate 53 overlap each other in the thickness direction. The end of the electromagnetic shielding member 40 is fixed by being clamped between the support body 52 and the second fixing plate 53.
[0049] like Figure 4 and Figure 6 As shown, the support body 52 has a first positioning hole 54 that penetrates the support body 52 in the thickness direction. The first positioning hole 54 is, for example, generally rectangular when viewed from the thickness direction of the support body 52. Multiple first positioning holes 54 are arranged, for example, along a first direction D3 perpendicular to the thickness direction of the support body 52. The multiple first positioning holes 54 are arranged, for example, along one long side of a generally rectangular second fixing plate 53. Furthermore, in the following description, a second direction D4 is defined as perpendicular to both the thickness direction of the support body 52 and the first direction D3. In this embodiment, the long side of the second fixing plate 53 is along the first direction D3, and the short side of the second fixing plate 53 is along the second direction D4.
[0050] The support body 52 has a positioning recess 55. The positioning recess 55 is, for example, formed by a notch. The positioning recess 55 is a notch that is recessed from the end of the support body 52 toward the first direction D3 when viewed from the thickness direction of the support body 52. Furthermore, for example, two positioning recesses 55 are provided. The positioning recesses 55 are, for example, respectively provided at both ends of the support body 52 in the first direction D3. The positioning recesses 55 are, for example, provided at positions corresponding to the two end edges of the second fixing plate 53 in the first direction D3, i.e., the two short sides of the second fixing plate 53.
[0051] like Figure 6 As shown, the second fixing plate 53 has a first notch 56 at one end in the second direction D4. The first notch 56 is a notch that is recessed from the end of the second fixing plate 53 toward the second direction D4 when viewed from the thickness direction of the second fixing plate 53. For example, multiple first notches 56 are arranged along the first direction D3. Each first notch 56 is, for example, formed to have the same shape and the same size as each other.
[0052] Each of the first notches 56 corresponds to a first positioning hole 54. That is, when the second fixing plate 53 is fixed to the bracket body 52, each of the first notches 56 and each of the first positioning holes 54 are located at the same position in the first direction D3. In addition, in the first direction D3, the width of the first positioning hole 54 and the width of the first notch 56 are formed to be equal to each other.
[0053] The first notch 56 is offset in the second direction D4 relative to the first positioning hole 54. Furthermore, viewed from the thickness direction of the second fixing plate 53, a portion of the first positioning hole 54 and a portion of the electromagnetic shielding member 40 are located within the region of the first notch 56. Within this region, for example, a portion of the first positioning hole 54 and a portion of the electromagnetic shielding member 40 are arranged in the second direction D4.
[0054] The second fixing plate 53 has a second notch 57 at its end in the first direction D3. The second notch 57 is a notch that is recessed from the end of the second fixing plate 53 toward the first direction D3 when viewed from the thickness direction of the second fixing plate 53.
[0055] The second notch 57 overlaps with the positioning recess 55 in the thickness direction of the support body 52 and the second fixing plate 53. Furthermore, the width of the second notch 57 and the width of the positioning recess 55 are equal in the second direction D4. Therefore, when assembling the support 51 and the electromagnetic shielding member 40, by overlapping the positioning recess 55 and the second notch 57, positioning of the second fixing plate 53 relative to the support body 52 in the first direction D3 and the second direction D4 can be achieved.
[0056] Furthermore, the support body 52 and the second fixing plate 53 are fixed to each other, for example, by riveting. Alternatively, the support body 52 and the second fixing plate 53 are fixed to each other using a punch (not shown) with the electromagnetic shielding member 40 between them. Multiple stamping portions of the punch are provided along the first direction D3. That is, multiple stamping marks A2 are formed on the support body 52 and the second fixing plate 53 along the first direction D3. The stamping marks A2 are recesses formed by the stamping of the punch.
[0057] Next, the method of fixing the electromagnetic shielding member 40 to the electromagnetic shielding cover 41 will be described. First, the fixing part 44 of the cover body 42 is integrally placed, for example, on the die of a riveting fixture (not shown). At this time, as... Figure 5 As shown, a plurality of first positioning pins P1 protruding from the die are respectively inserted into a plurality of first positioning holes 45 of the fixing part 44. Additionally, a plurality of second positioning pins P2 protruding from the die are respectively inserted into a plurality of second positioning holes 46 of the fixing part 44. Thus, the fixing part 44 is positioned relative to the die in both the first direction D1 and the second direction D2.
[0058] Next, the end of the electromagnetic shielding member 40 is placed on the fixing part 44 of the cover body 42 of the die. At this time, the end of the electromagnetic shielding member 40 in the second direction D2 can be positioned by making the edge of the electromagnetic shielding member 40 in the second direction D2 contact with the first positioning pins P1 protruding from the first positioning holes 45.
[0059] Next, a first fixing plate 43 is placed on the electromagnetic shielding member 40 mounted on the fixing part 44. At this time, a plurality of second positioning pins P2 are inserted into a plurality of second notches 48 of the first fixing plate 43. As a result, the first fixing plate 43 is positioned relative to the die and the fixing part 44 in the first direction D1 and the second direction D2.
[0060] Furthermore, multiple first positioning pins P1 are inserted into multiple first notches 47 of the first fixing plate 43. Thus, in the first direction D1, the first fixing plate 43 is positioned relative to the die and the fixing part 44. Additionally, in the second direction D2, a gap exists between the first positioning pins P1 and the edges of the first notches 47. The edges of the electromagnetic shielding member 40 can be visually confirmed through this gap. Therefore, with the electromagnetic shielding member 40 sandwiched between the fixing part 44 and the first fixing plate 43, the edge of the electromagnetic shielding member 40 can be viewed through the first notches 47 while the electromagnetic shielding member 40 is being aligned. Furthermore, after the electromagnetic shielding member 40 is aligned, the fixing part 44 and the first fixing plate 43 are fixed together with the electromagnetic shielding member 40 by, for example, riveting.
[0061] Next, the method of fixing the electromagnetic shielding component 40 to the bracket 51 will be described. First, the support body 52 is placed, for example, on the punching die. At this time, as... Figure 6 As shown, multiple first positioning pins P1 are inserted into multiple first positioning holes 54 of the bracket body 52. Additionally, multiple second positioning pins P2 are inserted into multiple positioning recesses 55 of the bracket body 52. Thus, the bracket body 52 is positioned relative to the die in the first direction D3 and the second direction D4.
[0062] Next, the end of the electromagnetic shielding member 40 is placed on the support body 52 of the die. At this time, the end of the electromagnetic shielding member 40 in the second direction D4 can be positioned by making the edge of the electromagnetic shielding member 40 in the second direction D4 contact with the first positioning pins P1 protruding from the first positioning holes 54.
[0063] Next, a second fixing plate 53 is placed on the electromagnetic shielding member 40 mounted on the support body 52. At this time, a plurality of second positioning pins P2 are inserted into a plurality of second notches 57 of the second fixing plate 53. As a result, the second fixing plate 53 is positioned relative to the die and the support body 52 in the first direction D3 and the second direction D4.
[0064] Furthermore, multiple first positioning pins P1 are inserted into multiple first notches 56 of the second fixing plate 53. Thus, in the first direction D3, the second fixing plate 53 is positioned relative to the die and support body 52. Additionally, in the second direction D4, a gap exists between the first positioning pins P1 and the edges of the first notches 56. The edges of the electromagnetic shielding member 40 can be visually confirmed through this gap. Therefore, with the electromagnetic shielding member 40 sandwiched between the support body 52 and the second fixing plate 53, the edge of the electromagnetic shielding member 40 can be viewed through the first notches 56 while the electromagnetic shielding member 40 is aligned. Furthermore, after the electromagnetic shielding member 40 is aligned, the support body 52 and the second fixing plate 53 are fixed together with the electromagnetic shielding member 40 by, for example, riveting.
[0065] The function of this embodiment will be explained. The electromagnetic shielding member 40 covers the sides of the multiple wires 13. Furthermore, the electromagnetic shielding member 40 is grounded via the housings of the first vehicle-mounted machine M1 and the second vehicle-mounted machine M2. Thus, the electromagnetic shielding member 40 can suppress, for example, electromagnetic waves radiating from the wires 13 to the outside.
[0066] The effects of this implementation method will be explained. (1) One end of the electromagnetic shielding member 40 is clamped and fixed by the cover body 42 and the first fixing plate 43. As a result, the reduction of the electromagnetic shielding effect of the electromagnetic shielding cover 41 can be suppressed and the electromagnetic shielding member 40 can be fixed to the electromagnetic shielding cover 41. In addition, since the bracket 51 is separated from the second connector 12, the bracket 51 can be grounded, for example, by mounting it to the housing of the vehicle-mounted machine.
[0067] (2) The second connector 12 includes: a second terminal 31 for connection to the wire 13; a second retaining member 32 made of synthetic resin for retaining the second terminal 31; and a terminal block 33 made of synthetic resin for mounting on the second vehicle-mounted machine M2. According to this structure, compared to cases where the terminal block 33 is made of metal, the connector unit 10 can be made lighter. Furthermore, since the bracket 51 is separated from the second connector 12, it does not become a structure where the bracket 51 is grounded via the terminal block 33 of the second connector 12. Therefore, it is not necessary to make the terminal block 33 from a conductor, increasing the freedom of choice in selecting the material of the terminal block 33.
[0068] (3) The electromagnetic shielding member 40 covers only one side of the multiple wires 13 in a direction perpendicular to the direction in which the multiple wires 13 are arranged. According to this structure, the increase in the number of electromagnetic shielding members 40 used in the connector unit 10 can be suppressed.
[0069] (4) In the electromagnetic shielding cover 41, the cover body 42 and the first fixing plate 43 are both plate-shaped and overlap each other in the thickness direction. The cover body 42 has a first positioning hole 45 for positioning through the cover body 42 in the thickness direction. The first fixing plate 43 has a first notch 47 at its end. The width of the first positioning hole 45 and the width of the first notch 47 in the first direction D1 are equal to each other. Furthermore, viewed from the thickness direction of the first fixing plate 43, a portion of the first positioning hole 45 and a portion of the electromagnetic shielding member 40 are located in the area of the first notch 47.
[0070] According to this structure, during the assembly of the electromagnetic shielding cover 41 and the electromagnetic shielding member 40, the first positioning hole 45 and the first notch 47 are overlapped, thereby enabling the positioning of the first fixing plate 43 relative to the fixing part 44. Furthermore, when the electromagnetic shielding member 40 is sandwiched between the fixing part 44 and the first fixing plate 43, the edge of the electromagnetic shielding member 40 can be visually confirmed via the first notch 47 to be near the end of the first fixing plate 43. Therefore, the electromagnetic shielding member 40 can be aligned while being viewed through the first notch 47. Thus, the alignment of the electromagnetic shielding member 40 becomes easier. As a result, the workability of fixing the electromagnetic shielding cover 41 and the electromagnetic shielding member 40 together is improved.
[0071] (5) In the bracket 51, the bracket body 52 and the second fixing plate 53 are both plate-shaped and overlap each other in the thickness direction. The bracket body 52 has a first positioning hole 54 for positioning through the bracket body 52 in the thickness direction. The second fixing plate 53 has a first notch 56 at its end. The width of the first positioning hole 54 and the width of the first notch 56 in the first direction D3 are equal to each other. Furthermore, viewed from the thickness direction of the second fixing plate 53, a portion of the first positioning hole 54 and a portion of the electromagnetic shielding member 40 are located in the area of the first notch 56.
[0072] According to this structure, during the assembly of the bracket 51 and the electromagnetic shielding member 40, the second fixing plate 53 can be positioned relative to the bracket body 52 by overlapping the first positioning hole 54 and the first notch 56. Furthermore, when the electromagnetic shielding member 40 is sandwiched between the bracket body 52 and the second fixing plate 53, the edge of the electromagnetic shielding member 40 can be visually confirmed via the first notch 56 to be near the end of the second fixing plate 53. Therefore, the electromagnetic shielding member 40 can be aligned while being viewed through the first notch 56. Thus, the alignment of the electromagnetic shielding member 40 becomes easier. As a result, the workability of fixing the bracket 51 and the electromagnetic shielding member 40 together is improved.
[0073] (6) In the electromagnetic shielding cover 41, a plurality of first positioning holes 45 are arranged along a first direction D1 perpendicular to the thickness direction of the fixing part 44. Furthermore, a plurality of first notches 47 are arranged along the first direction D1, corresponding to each of the plurality of first positioning holes 45. According to this structure, when the electromagnetic shielding cover 41 and the electromagnetic shielding member 40 are assembled, by overlapping the first positioning holes 45 of the fixing part 44 and the first notches 47 of the first fixing plate 43, the first fixing plate 43 can be positioned more appropriately relative to the fixing part 44.
[0074] Furthermore, in the bracket 51, multiple first positioning holes 54 are arranged along a first direction D3 perpendicular to the thickness direction of the bracket body 52. Also, multiple first notches 56 are arranged along the first direction D3, each corresponding to one of the multiple first positioning holes 54. According to this structure, when assembling the bracket 51 and the electromagnetic shielding member 40, by overlapping the first positioning holes 54 of the bracket body 52 and the first notches 56 of the second fixing plate 53, the second fixing plate 53 can be positioned more appropriately relative to the bracket body 52.
[0075] (7) The first fixing plate 43 has a second notch 48 at its end in the first direction D1. The fixing part 44 has a second positioning hole 46 that overlaps with the second notch 48 in the plate thickness direction. Furthermore, in the second direction D2, which is perpendicular to both the plate thickness direction and the first direction D1 of the fixing part 44, the width of the second notch 48 and the width of the second positioning hole 46 are equal. According to this structure, when the electromagnetic shielding cover 41 and the electromagnetic shielding member 40 are assembled, by overlapping the second positioning hole 46 of the fixing part 44 and the second notch 48 of the first fixing plate 43, positioning of the first fixing plate 43 relative to the fixing part 44 in the first direction D1 and the second direction D2 can be achieved.
[0076] Furthermore, the second fixing plate 53 has a second notch 57 at its end in the first direction D3. The bracket body 52 has a positioning recess 55 that overlaps with the second notch 57 in the plate thickness direction. Moreover, in the second direction D4, which is perpendicular to both the plate thickness direction and the first direction D3 of the bracket body 52, the width of the second notch 57 and the width of the positioning recess 55 are equal. According to this structure, when the bracket 51 and the electromagnetic shielding member 40 are assembled, by overlapping the positioning recess 55 of the bracket body 52 and the second notch 57 of the second fixing plate 53, positioning of the second fixing plate 53 relative to the bracket body 52 in the first direction D3 and the second direction D4 can be achieved.
[0077] (8) The first fixing plate 43 of the electromagnetic shielding cover 41 and the second fixing plate 53 of the bracket 51 are of the same shape. According to this structure, the first fixing plate 43 and the second fixing plate 53 can be treated as the same component. Therefore, the component management of the connector unit 10 can be prevented from becoming complicated.
[0078] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other within the scope of technical inconsistency. The structure of the electromagnetic shielding member 40 is not limited to the woven sheet of the above embodiment. In addition, the electromagnetic shielding member 40 may also be made of metal foil or the like.
[0079] • The material of the terminal block 33 is not limited to synthetic resin, and can be changed to metal, for example. In the electromagnetic shielding cover 41 of the above embodiment, when viewed from the thickness direction of the first fixing plate 43, a portion of the first positioning hole 45 is located within the area of the first notch 47. However, it is not limited to this, and it may also be configured such that, when viewed from the thickness direction of the first fixing plate 43, the entire first positioning hole 45 is located within the area of the first notch 47.
[0080] In the bracket 51 of the above embodiment, when viewed from the thickness direction of the second fixing plate 53, a portion of the first positioning hole 54 is located within the area of the first notch 56. However, it is not limited to this, and it may also be configured such that, when viewed from the thickness direction of the second fixing plate 53, the entire first positioning hole 54 is located within the area of the first notch 56.
[0081] • Alternatively, the first fixing plate 43 and the second fixing plate 53 can be set to different shapes. • In the fixing part 44, the number of the first positioning holes 45 and the number of the second positioning holes 46 are not limited to the above embodiment, and can be appropriately changed according to the structure of the electromagnetic shielding cover 41. In addition, in the first fixing plate 43, the number of the first notch 47 and the number of the second notch 48 are not limited to the above embodiment, and can be appropriately changed according to the structure of the electromagnetic shielding cover 41.
[0082] • In the bracket body 52, the number of the first positioning holes 54 and the number of positioning recesses 55 are not limited to the above embodiment, and can be appropriately changed according to the structure of the bracket 51. In addition, in the second fixing plate 53, the number of the first notches 56 and the number of the second notches 57 are not limited to the above embodiment, and can be appropriately changed according to the structure of the bracket 51.
[0083] In the bracket 51 of the above embodiment, the end of the electromagnetic shielding member 40 is clamped and fixed by the bracket body 52 and the second fixing plate 53. However, in addition, for example, the second fixing plate 53 may be omitted from the bracket 51, and the bracket may be configured such that the end of the electromagnetic shielding member 40 is clamped and fixed by a bending fixing part formed by bending and deforming a part of the bracket body 52 in a way that folds back.
[0084] In the electromagnetic shielding cover 41 of the above embodiment, the fixing part 44 and the first fixing plate 43 are fixed to each other by riveting with a punch. However, in addition to this, the fixing part 44 and the first fixing plate 43 may also be fixed by ultrasonic welding, welding or the like.
[0085] In the bracket 51 described above, the bracket body 52 and the second fixing plate 53 are fixed to each other by riveting with a punch. However, in addition to this, the bracket body 52 and the second fixing plate 53 may also be fixed by means of ultrasonic welding, welding, or the like.
[0086] ·like Figure 2 As shown, the first connector 11 and the second connector 12 can also be fixed to the vehicle-mounted machines M1 and M2, which are to be assembled, in a bent position with multiple wires 13. That is, the multiple wires 13 can also have a first end fixed to the first connector 11, a second end fixed to the second connector 12, a bend between the first end and the second end, a first length portion between the first end and the bend, and a second length portion between the second end and the bend.

The bracket 51 can also protrude beyond the bends of each wire 13 into the extension direction of the first length portion. The electromagnetic shielding member 40 can also face the first length portion of the multiple wires 13, but not face the second length portion of the multiple wires 13. In addition, the electromagnetic shielding member 40 is sometimes referred to as a mesh electromagnetic shielding member or an electromagnetic shielding sheet.

In addition, the bracket 51 is sometimes referred to as an electromagnetic shielding bracket.
