Modes for Carrying Out the Invention

[0010] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The conductive sheet with a metal plate of the present disclosure is as follows.

[0012] (1) A conductive sheet, a metal plate, and a sheet fixing member separate from the metal plate, wherein a part of the conductive sheet is sandwiched between the metal plate and the sheet fixing member, and the sheet fixing member is overlapped and fixed on the metal plate. A positioning concave portion is formed on one of the metal plate and the sheet fixing member, and a positioning convex portion that contacts and is positioned at the edge of the positioning concave portion is formed on the other. It is a conductive sheet with a metal plate. According to the present disclosure, the sheet fixing member is overlapped on the metal plate in a state where the positioning convex portion contacts and is positioned at the edge of the positioning concave portion. Therefore, the metal plate and the sheet fixing member that sandwich the conductive sheet are easily positioned.

[0013] (2) The conductive sheet with a metal plate according to (1), wherein the conductive sheet may contact the positioning convex portion. The conductive sheet is also positioned with reference to the positioning convex portion.

[0014] (3) The conductive sheet with a metal plate according to (2), wherein a window portion for making the edge of the conductive sheet in contact with the positioning convex portion visible is formed at a position adjacent to the positioning convex portion on the other of the metal plate and the sheet fixing member. It is easy to confirm whether the conductive sheet is inserted until it contacts the positioning convex portion.

[0015] (4) The conductive sheet with a metal plate according to any one of (1) to (3), wherein the positioning concave portion includes a positioning hole portion whose entire periphery is surrounded by an edge, and the positioning convex portion may fit into the positioning hole portion. Since the positioning convex portion fits into the positioning hole portion, the sheet fixing member is more reliably positioned with respect to the metal plate.

[0016] (5) The conductive sheet with a metal plate according to any one of (1) to (4), wherein the positioning concave portion includes a positioning notch portion partially surrounded by an edge, and the positioning convex portion may contact the edge of the positioning notch portion. While visually recognizing the positioning convex portion, it is easy to relatively move the positioning convex portion toward the positioning notch portion, and the positioning convex portion can be easily positioned by the positioning notch portion.

[0017] (6) A conductive sheet with a metal plate according to any one of (1) to (5), wherein the positioning recess may be formed in the metal plate, and the positioning protrusion may be formed in the sheet fixing member. Even if the sheet fixing member has a shape that is difficult to distinguish between front and back, the front and back can be easily distinguished by using the protruding direction of the positioning protrusion as a clue.

[0018] (7) A conductive sheet with a metal plate according to any one of (1) to (6), wherein the sheet fixing member is a plate formed of metal, and the metal plate and the sheet fixing member may be fixed to each other by a mechanical clinch portion. The metal plate and the sheet fixing member can be easily fixed.

[0019] [Details of Embodiments of the Present Disclosure] Specific examples of the conductive sheet with a metal plate of the present disclosure will be described below with reference to the drawings. It should be noted that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0020] [Embodiment] Hereinafter, a conductive sheet with a metal plate according to an embodiment will be described. FIG. 1 is an explanatory diagram showing an example in which a conductive sheet 30 with a metal plate is provided between two electrical devices 10 and 14 (first electrical device 10, second electrical device 14). The two electrical devices 10 and 14 may be devices mounted on a vehicle or the like, for example. As combinations of the two electrical devices 10 and 14, there may be a motor for driving a vehicle in an electric vehicle and an inverter for driving the motor, or an inverter for driving a motor and a battery for supplying power to the inverter.

[0021] The first electrical device 10 has a configuration in which electrical components are housed in a housing 11. The second electrical device 14 also has a configuration in which electrical components are housed in a housing 15. The housings 11 and 15 are, for example, conductive housings formed of a conductive member such as metal.

[0022] The wiring member 20 is connected to at least one of the two electrical devices 10 and 14. In FIG. 1, a state where one end of the wiring member 20 is connected to the first electrical device 10 is shown. In the present embodiment, the wiring member 20 is a member for connecting the first electrical device 10 to other electrical devices or the like. The other end of the wiring member 20 may be connected to the second electrical device 14 or may be connected to other electrical devices.

[0023] The wiring member 20 includes a transmission member 22 and a connection portion 24.

[0024] The transmission member 22 is a member in which an insulating portion made of resin or the like is formed around at least one linear conductor. The transmission member 22 may be a member in which a plurality of covered electric wires are gathered. The transmission member may be configured such that a plurality of linear conductors are buried in one insulating portion in a mutually insulated state.

[0025] The connection portion 24 is provided at one end of the transmission member 22. The connection portion 24 is a member that connects the linear conductor of the transmission member 22 to an electrical component in the first electrical device 10. The connection portion 24 is, for example, a member including a terminal and a housing that holds the terminal. In a state where the housing in the connection portion 24 is attached to the housing 11 by a fitting structure, a screw fastening structure, or the like, the terminal held by the housing is kept in a state of being connected to an electrical component in the first electrical device 10.

[0026] The above connection portion 24 is covered with a metal cover 26. The metal cover 26 is a member formed by pressing a metal plate such as copper, a copper alloy, aluminum, or an aluminum alloy. The metal cover 26 is formed in a shape that covers, on the surface of the housing 11, portions of the connection portion 24 other than the portion where the transmission member 22 extends. The metal cover 26 is fixed to the housing 11 by screw fastening or the like. This metal cover 26 can serve to electromagnetically shield the end of the transmission member 22 and the connection portion 24.

[0027] The conductive sheet 30 with a metal plate is an electromagnetic shielding member that covers at least a part of the wiring member 20. Here, the conductive sheet 30 with a metal plate includes a conductive sheet 40, a metal plate 50, and a sheet fixing member 60 that is separate from the metal plate 50. The metal plate 50 and the sheet fixing member 60 are fixed to one end of the conductive sheet 40. The metal plate 50 is fixed to the housing 11 of the second electrical device 14. Also, the other end of the conductive sheet 40 is fixed to the metal cover 26. Therefore, the conductive sheet 40 is supported at a fixed position so as to span between the metal cover 26 fixed to the first electrical device 10 and the housing 15 of the second electrical device 14.

[0028] The wiring member 20 extends on the side closer to the housing 11 than the conductive sheet 40 and on the same side as the direction in which the conductive sheet 40 extends from the connection portion 24. Therefore, at least the end portion of the wiring member 20 on the side of the first electrical device 10 is covered by the conductive sheet 40. In this regard, the conductive sheet 30 with a metal plate is an electromagnetic shielding member that electromagnetically shields at least a part of the wiring member 20.

[0029] Hereinafter, the configuration in which one end of the conductive sheet 40 is fixed to the metal plate 50 and the sheet fixing member 60 will be mainly described. FIG. 2 is a perspective view showing the conductive sheet 30 with a metal plate. FIG. 3 is an exploded perspective view of the conductive sheet 30 with a metal plate. FIG. 4 is a partial cross-sectional view taken along line IV-IV in FIG. 2.

[0030] The conductive sheet 40 is a conductive member formed in a sheet shape. The conductive sheet 40 is formed, for example, by braiding metal wires. The braided metal wires include braids, metal cloth, metal nets, etc. The conductive sheet 40 is formed in a shape that spreads in a rectangular shape. The metal plate 50 and the sheet fixing member 60 are fixed to one end of the conductive sheet 40. The length of the conductive sheet 40 is, for example, a size that can be disposed across the first electrical device 10 and the second electrical device 14. The width of the conductive sheet 40 is, for example, a size such that the transmission member 22 can be covered from the side opposite to the first electrical device 10.

[0031] The metal plate 50 and the sheet fixing member 60 are members that keep the conductive sheet 40 covering a part of the wiring member 20. Here, the metal plate 50 and the sheet fixing member 60, together with the metal cover 26, keep the conductive sheet 40 covering a part of the wiring member 20.

[0032] The metal plate 50 is a member formed by pressing a metal plate such as copper, a copper alloy, aluminum, or an aluminum alloy. The metal plate 50 includes a sandwiching and fixing main body portion 52 and a fixing piece 56.

[0033] The sandwiching and fixing main body portion 52 is formed in a rectangular plate shape, more specifically, in an elongated rectangular plate shape. The longitudinal dimension of the sandwiching and fixing main body portion 52 is formed to be the same as or larger than the width of the conductive sheet 40.

[0034] The fixing piece 56 is formed so as to extend outward from the outer periphery of the sandwiching and fixing main body portion 52. Here, the fixing piece 56 is formed so as to extend outward from one long side portion of the sandwiching and fixing main body portion 52. The direction in which the fixing piece 56 extends is a direction avoiding the direction in which the conductive sheet 40 extends from the sandwiching and fixing main body portion 52. Here, the fixing piece 56 extends in a direction opposite to the direction in which the conductive sheet 40 extends with respect to the sandwiching and fixing main body portion 52. The fixing piece 56 is a portion fixed to a fixing target portion such as the housing 15. In the present embodiment, a screw insertion hole 56h is formed in the fixing piece 56. In a state where a screw S is inserted into the screw insertion hole 56h, the screw S is screwed and fastened to a screw groove formed in the housing 15. Thereby, the fixing piece 56 is fixed to the housing 15. The fixing piece 56 may be fixed to the housing 15 by other configurations, for example, welding, riveting, caulking, etc.

[0035] The fixing piece 56 is bent with respect to the sandwiching and fixing main body portion 52 to one main surface side of the sandwiching and fixing main body portion 52. Therefore, one main surface and the other main surface of the metal plate 50 can be distinguished based on the direction in which the sandwiching and fixing main body portion 52 bends. However, the fixing piece 56 may extend without bending with respect to the sandwiching and fixing main body portion 52.

[0036] The sheet fixing member 60 is a member formed separately from the metal plate 50. The sheet fixing member 60 is overlapped and fixed on the metal plate 50 with one end portion, which is a part of the conductive sheet 40, sandwiched between the metal plate 50 and the sheet fixing member 60.

[0037] The sheet fixing member 60 may be any member that can be overlapped on the metal plate 50, and its shape is not particularly limited. For example, the sheet fixing member 60 may be plate-shaped or rectangular parallelepiped-shaped. The material of the sheet fixing member 60 is also not particularly limited. The sheet fixing member 60 may be a metal such as copper, copper alloy, aluminum, aluminum alloy, etc., or may be a resin.

[0038] In this embodiment, the sheet fixing member 60 is composed of a metal plate such as copper, copper alloy, aluminum, aluminum alloy, etc. Here, the sheet fixing member 60 is formed in a rectangular plate shape, more specifically, an elongated rectangular plate shape. The longitudinal dimension of the sheet fixing member 60 is formed to be the same as or larger than the width of the conductive sheet 40. Fixing pieces or the like for fixing to the portion to be fixed may also be integrally formed on the sheet fixing member 60.

[0039] In this embodiment, the longitudinal dimension of the sheet fixing member 60 is smaller than the longitudinal dimension of the sandwiching and fixing main body portion 52, and the short-side dimension of the sheet fixing member 60 is smaller than the short-side dimension of the sandwiching and fixing main body portion 52.

[0040] A positioning recess 54 is formed in one of the metal plate 50 and the sheet fixing member 60, and a positioning projection 62 is formed in the other. Here, an example is shown in which the positioning recess 54 is formed in the metal plate 50 and the positioning projection 62 is formed in the sheet fixing member 60.

[0041] More specifically, a positioning recess 54 is formed in a portion of the sandwiching and fixing main body portion 52 of the metal plate 50 closer to the fixing piece 56. The positioning recess 54 may be one or a plurality. In the present embodiment, a plurality (here, two) of positioning recesses 54 are formed at intervals in the longitudinal direction of the sandwiching and fixing main body portion 52.

[0042] The positioning recess 54 may be a recess that can regulate the position of the positioning protrusion 62 in at least one direction by bringing the positioning protrusion 62 into contact therewith. Here, an example in which the positioning recess 54 is a positioning hole portion surrounded by an edge on the entire periphery will be described. The positioning recess 54 may not be a positioning hole portion, but may be a recess partially surrounded by an edge and the rest being open. A modification example in that case will be described later with reference to FIG. 5 or FIG. 6. Further, the positioning recess 54 as the positioning hole portion in the present embodiment is a hole penetrating the metal plate 50. However, the positioning recess 54 as the positioning hole portion does not necessarily need to penetrate the metal plate 50 and may be a blind hole. Further, the opening shape of the positioning recess 54 is not particularly limited. In the present embodiment, the positioning recess 54 is formed in a square hole shape. The opening shape of the positioning recess 54 may be other polygonal shapes such as a circular shape, an elliptical shape, a slit shape, and a triangular shape.

[0043] The positioning protrusion 62 is formed on one long side portion of the sheet fixing member 60. The positioning protrusion 62 may be one or a plurality. In the present embodiment, corresponding to the plurality of positioning recesses 54, a plurality (here, two) of positioning protrusions 62 are formed at intervals along one long side portion of the sheet fixing member 60. The intervals between the plurality of positioning recesses 54 and the intervals between the plurality of positioning protrusions 62 are the same.

[0044] The positioning convex portion 62 is formed by extending a part of one long side portion of the sheet fixing member 60 in a strip shape and bending this extended portion to the one main surface side of the sheet fixing member 60. More specifically, a partial recess 61 is formed in one long side portion of the sheet fixing member 60. A strip-shaped portion extends from the inner portion of this recess 61. By bending this strip-shaped portion to the one main surface side of the sheet fixing member 60, the positioning convex portion 62 is formed. The positioning convex portion 62 protrudes from one main surface of the sheet fixing member 60.

[0045] The width dimension of the positioning convex portion 62 may be smaller than the width dimension of the recess 61. Also, the inward-facing surface 62f of the positioning convex portion 62 may be located outside the inner portion 61a of the recess 61. In this case, when the sheet fixing member 60 is viewed from the side opposite to the metal plate 50, a gap 61s is formed outside the positioning convex portion 62.

[0046] Then, with the sheet fixing member 60 superposed on the metal plate 50, the positioning convex portion 62 is fitted into the positioning recess 54 (see arrow P2 in FIG. 3). At this time, the positioning convex portion 62 is positioned in contact with any one of the peripheral edges of the positioning recess 54. For this reason, the sheet fixing member 60 is positioned with respect to the metal plate 50. At this time, by positioning the plurality of positioning convex portions 62 in the plurality of positioning recesses 54, the rotation of the sheet fixing member 60 with respect to the metal plate 50 is restricted.

[0047] With the sheet fixing member 60 superposed on the metal plate 50, one end portion of the conductive sheet 40 is sandwiched between the metal plate 50 and the sheet fixing member 60. More specifically, with the width direction of one end portion of the conductive sheet 40 aligned with the longitudinal direction of the sandwiching and fixing main body portion 52 of the metal plate 50 and the sheet fixing member 60 (see arrow P1 in FIG. 3), one end portion of the conductive sheet 40 is sandwiched between the metal plate 50 and the sheet fixing member 60.

[0048] At this time, the conductive sheet 40 may be in a state of contacting the positioning convex portion 62. Here, the edge of one end portion of the conductive sheet 40 is in a state of contacting the inner portion of the plurality of positioning convex portions 62. Therefore, the conductive sheet 40 is sandwiched at a fixed position with respect to the metal plate 50 and the sheet fixing member 60.

[0049] On the other side of the metal plate 50 and the sheet fixing member 60 (that is, the side where the positioning convex portion 62 is formed), a window portion is formed at a position adjacent to the positioning convex portion 62 to make the edge of the conductive sheet 40 in contact with the positioning convex portion 62 visible. Here, the gap 61s is formed as a window portion outside the positioning convex portion 62. By checking whether the edge of one end portion of the conductive sheet 40 can be visually recognized through the gap 61s, it can be confirmed whether the edge of one end portion of the conductive sheet 40 exists at a predetermined position in contact with the inner portion of the plurality of positioning convex portions 62.

[0050] The metal plate 50 and the sheet fixing member 60 are fixed in a superimposed state. In the present embodiment, the metal plate 50 and the sheet fixing member 60 are fixed by a mechanical clinch portion 70. Here, the mechanical clinch means maintaining two metal plates in a superimposed state by a mechanical fitting structure of a convex portion formed on one of the two metal plates and a concave portion formed on the other. The mechanical clinch portion 70 is such a fitting structure portion of the convex portion 72 and the concave portion 74.

[0051] In the example shown in FIGS. 2 and 4, the convex portion 72 is formed on the sheet fixing member 60, and the concave portion 74 is formed on the metal plate 50. The convex portion 72 is fitted into the concave portion 74, and the sheet fixing member 60 is kept in a state of being superimposed on the metal plate 50. The concavo-convex relationship may be reversed between the sheet fixing member 60 and the metal plate 50.

[0052] The mechanical crimping portion 70 as described above can be formed, for example, by performing press working on the metal plate 50 and the sheet fixing member 60 in a superposed state to partially plastically deform the metal plate 50 and the sheet fixing member 60. Further, during or after the press working, the base end side portion of the convex portion 72 and the opening side portion of the concave portion 74 may be plastically deformed so as to be narrowed. In this case, the tip side portion of the convex portion 72 spreads more than its base end side portion, and the back side portion of the concave portion 74 is in a state of spreading more than its opening side portion. Thereby, it becomes difficult for the convex portion 72 to come out of the concave portion 74.

[0053] It is only necessary that the metal plate 50 and the sheet fixing member 60 be kept in a superposed state by the mechanical crimping portion 70. The position and number of the mechanical crimping portions 70 in the superposed portion of the metal plate 50 and the sheet fixing member 60 are arbitrary. For example, one mechanical crimping portion may be formed at the center in the longitudinal direction of the sheet fixing member 60. Further, for example, a pair of mechanical crimping portions may be formed at both ends in the longitudinal direction of the sheet fixing member 60. In the present embodiment, an example is shown in which a plurality (here, five) of mechanical crimping portions 70 are formed at intervals along the longitudinal direction of the sheet fixing member 60.

[0054] In the present embodiment, the mechanical crimping portion 70 exists in a region where the metal plate 50 and the sheet fixing member 60 sandwich a part of the conductive sheet 40. For this reason, in the mechanical crimping portion 70, the conductive sheet 40 is sandwiched between the convex portion 72 and the concave portion 74 in the mechanical crimping portion 70. Further, the conductive sheet 40 is strongly sandwiched between the metal plate 50 and the sheet fixing member 60 around the mechanical crimping portion 70. Note that the position of the mechanical crimping portion 70 with respect to the arrangement region of the conductive sheet 40 is arbitrary. For example, some or all of the mechanical crimping portions may exist outside the region where the metal plate 50 and the sheet fixing member 60 sandwich a part of the conductive sheet 40.

[0055] The metal plate 50 and the sheet fixing member 60 may be fixed in a superposed state by a configuration that is not the mechanical clinch portion 70. For example, the metal plate 50 and the sheet fixing member 60 may be fixed in a superposed state by welding, caulking, soldering, screwing, or the like.

[0056] According to the conductive sheet 30 with a metal plate configured as described above, with the positioning convex portion 62 in contact with and positioned at the edge of the positioning concave portion 54, the sheet fixing member 60 is superposed on the metal plate 50. For this reason, the metal plate 50 and the sheet fixing member 60 that sandwich the conductive sheet 40 are easily positioned. And since one end portion of the conductive sheet 40 is sandwiched and fixed between the accurately positioned metal plate 50 and the sheet fixing member 60, a conductive sheet 30 with a metal plate of stable quality can be manufactured.

[0057] Also, with the conductive sheet 40 in contact with the positioning convex portion 62, the conductive sheet 40 is sandwiched between the metal plate 50 and the sheet fixing member 60. For this reason, the amount of the conductive sheet 40 sandwiched by the metal plate 50 and the sheet fixing member 60 is stable, and the fixing state of the conductive sheet 40 with respect to the metal plate 50 and the sheet fixing member 60 is stable.

[0058] Also, the positioning concave portion 54 is formed as a positioning hole portion whose entire periphery is surrounded by an edge. For this reason, the positioning convex portion 62 is positioned in all directions within the positioning concave portion 54. Thereby, the sheet fixing member 60 is more reliably positioned with respect to the metal plate 50.

[0059] Further, a positioning recess 54 is formed in the metal plate 50, and a positioning projection 62 is formed in the sheet fixing member 60. Here, the metal plate 50 has a shape portion that serves other functions, such as the fixing piece 56, and it is conceivable that the front and back surfaces can be easily distinguished. On the other hand, since the sheet fixing member 60 is a member solely for fixing the conductive sheet 40, it is conceivable that it has a simple shape. Here, since the sheet fixing member 60 is in the shape of an elongated rectangular plate, it can be observed as having the same shape when viewed from any surface. However, when observing the sheet fixing member 60 in detail, the front and back surfaces may be distinguished depending on the presence or absence of surface treatment on the two surfaces, the difference in roughness, the presence or absence of burrs on the edges due to press working, etc. Therefore, if the positioning projection 62 is formed on the sheet fixing member 60, the front and back surfaces of the sheet fixing member 60 can be identified using the protruding direction of the positioning projection 62 as a clue.

[0060] For example, it is conceivable to project the positioning projection 62 on the side opposite to the surface where burrs are generated by press working. As a result, in a state where the sheet fixing member 60 is overlapped with the metal plate 50, it becomes difficult for the burrs to come into contact with the conductive sheet 40.

[0061] Further, the metal plate 50 and the sheet fixing member 60 are fixed in an overlapped state by the mechanical clinch portion 70. Therefore, the metal plate 50 and the sheet fixing member 60 can be easily fixed by press working or the like. In particular, the fixing workability is good compared to a configuration in which separate fixing parts such as rivet fastening and screw fixing are used for fixing.

[0062] [Modification Example] A modification example will be described. FIG. 5 is a perspective view showing a conductive sheet with a metal plate 130 according to the first modification example. The conductive sheet with a metal plate 130 includes a conductive sheet 40, a metal plate 150, and a sheet fixing member 160.

[0063] The metal plate 150 is formed in an elongated rectangular shape. Positioning recesses 154 are formed in the middle portions in the extending directions of the edges on both sides of the metal plate 150. The positioning recesses 154 are formed in a shape that is partially recessed in a rectangular shape from the edges of the metal plate 150. These positioning recesses 154 are formed in a shape where three sides of the periphery are surrounded by edges and the remaining one direction is open to the outside. Such positioning recesses 154 are an example of positioning notch portions partially surrounded by edges. A fixing piece for fixing to a portion to be fixed may be integrally formed on the metal plate 150.

[0064] The sheet fixing member 160 is formed in an elongated plate shape by a metal plate. Positioning protrusions 162 are formed in the middle portions in the extending directions of the edges on both sides of the sheet fixing member 160. The positioning protrusions 162 protrude from the edges of the sheet fixing member 160 to one surface side of the sheet fixing member 160. Here, a part of both side edges of the sheet fixing member 160 is extended in a strip shape, and this strip-shaped portion is bent to one surface side of the sheet fixing member 160 to form the positioning protrusions 162. Then, with the positioning protrusions 162 in contact with the three edges of the positioning recesses 154, the sheet fixing member 160 is overlapped on the metal plate 150. For this reason, the sheet fixing member 160 is accurately positioned with respect to the metal plate 150. In particular, by fitting the two positioning protrusions 162 into the positioning recesses 154, the metal plate 150 and the sheet fixing member 160 are positioned relative to each other in the short side direction of the metal plate 150. Also, at both longitudinal ends of the metal plate 150, by fitting the positioning protrusions 162 into the positioning recesses 154, the metal plate 150 and the sheet fixing member 160 are positioned relative to each other in the long side direction of the metal plate 150 as well. In this state, the metal plate 150 and the sheet fixing member 160 are fixed by a mechanical clinch portion 170 corresponding to the mechanical clinch portion 70.

[0065] The end of the conductive sheet 40 is sandwiched and fixed between the metal plate 150 and the sheet fixing member 160. Confirmation windows 150h and 160h are formed on the edges on the long side of the metal plate 150 and the sheet fixing member 160, on the side opposite to the side where the conductive sheet 40 extends. Here, a plurality of confirmation windows 150h and 160h are formed at intervals in the direction along each of the edges. The confirmation windows 150h and 160h are formed in a shape that is recessed inward in a rectangular shape from a part of the edges on the long side of the metal plate 150 and the sheet fixing member 160. One end of the conductive sheet 40 is sandwiched between the metal plate 150 and the sheet fixing member 160 so that the edge of one end of the conductive sheet 40 reaches the confirmation windows 150h and 160h. By checking the presence or absence of the edge of one end of the conductive sheet 40 through the confirmation windows 150h and 160h, the sandwiching state of the conductive sheet 40 by the metal plate 150 and the sheet fixing member 160 can be confirmed.

[0066] As in this modification, the positioning recess 154 may be a positioning notch portion that is partly surrounded by an edge and the other part is open. In this case, since a part around the positioning recess 154 is open, it is easy to relatively move the positioning projection 162 toward the positioning recess 154 while checking the positional relationship between the positioning projection 162 and the positioning recess 154, and the positioning projection 162 can be easily positioned by the positioning recess 154.

[0067] FIG. 6 is a perspective view showing a conductive sheet with a metal plate 230 according to a second modification. The conductive sheet with a metal plate 230 includes a conductive sheet 40, a metal plate 250, and a sheet fixing member 260.

[0068] The metal plate 250 is formed in an elongated rectangular shape. Positioning projections 254 are formed inside the edges on both sides of the metal plate 250. The positioning projections 254 are formed in a shape that protrudes on one surface side of the metal plate 250. Here, the positioning projections 254 are formed by forming linear slits inside the edges on both sides of the metal plate 250 and bending the outer part from the part where the slits are formed.

[0069] Also, a convex portion 256 is formed inside the edge on one long side of the metal plate 250. The convex portion 256 is formed in a shape protruding to one surface side of the metal plate 250. Here, the convex portion 256 is formed by forming a linear slit inside the edge on the long side of the metal plate 250 and bending up the outer portion from the portion where the slit is formed. Here, two convex portions 256 are formed at intervals inside the edge on one long side of the metal plate 250.

[0070] The sheet fixing member 260 is formed in an elongated plate shape by a metal plate. The length dimension in the long side direction of the sheet fixing member 260 is smaller than the length dimension in the long side direction of the metal plate 250, and the length dimension in the short side direction of the sheet fixing member 260 is also smaller than the length dimension in the short side direction of the metal plate 250.

[0071] Positioning recesses 262 are formed in the middle portions in the extending directions of the edges on both sides of the sheet fixing member 260. The positioning recesses 262 are formed in a shape that is partially recessed in a rectangular shape from their edges. The present positioning recess 262 is an example of a positioning notch portion that is partially surrounded by an edge and the other is open. A recess 264 is formed at a position corresponding to the convex portion 256 on one long side edge of the sheet fixing member 260. The recess 264 is formed in a shape that is partially recessed in a rectangular shape from its edge.

[0072] Then, with the positioning convex portion 254 in contact with the three edges of the positioning recess 262, the sheet fixing member 260 is overlapped on the metal plate 250. For this reason, similar to the first modification example 1, the sheet fixing member 260 is accurately positioned with respect to the metal plate 250. In this state, the metal plate 250 and the sheet fixing member 260 are fixed by a mechanical clinch portion 270 corresponding to the mechanical clinch portion 70.

[0073] The end of the conductive sheet 40 is sandwiched and fixed between the metal plate 250 and the sheet fixing member 260. As described above, with the metal plate 250 and the sheet fixing member 260 overlapped, the convex portion 256 is disposed within the concave portion 264 at a position away from the depth of the concave portion 264. One end of the conductive sheet 40 is sandwiched between the metal plate 250 and the sheet fixing member 260 such that the edge of one end of the conductive sheet 40 contacts the convex portion 256. Therefore, by using the convex portion 256 as a positioning portion for the conductive sheet 40, the conductive sheet 40 can be sandwiched between the metal plate 250 and the sheet fixing member 260, thereby stabilizing the sandwiched state of the conductive sheet 40 by the metal plate 250 and the sheet fixing member 260. Moreover, when the edge of one end of the conductive sheet 40 is in contact with the convex portion 256, the edge of one end of the conductive sheet 40 can be confirmed between the depth of the concave portion 264 and the convex portion 256. Therefore, by checking the presence or absence of the edge of one end of the conductive sheet 40 between the depth of the concave portion 264 and the convex portion 256, it is confirmed whether the end of the conductive sheet 40 is sandwiched at a predetermined position.

[0074] Note that both side portions of the convex portion 256 are in contact with both side edges of the concave portion 264. In this regard, the convex portion 256 may be regarded as an example of a positioning convex portion, and the concave portion 264 may be regarded as an example of a positioning concave portion.

[0075] Also in this Modification 2, since a part of the periphery of the positioning concave portion 262 is open, it is easy to relatively move the positioning convex portion 254 toward the positioning concave portion 262 while checking the positional relationship between the positioning convex portion 254 and the positioning concave portion 262, and the positioning convex portion 254 can be easily positioned by the positioning concave portion 262.

[0076] Note that the attachment structure of the other end of the conductive sheet 40 to the metal cover 26 may be the same as the configuration described in the above embodiment or each modification, or may be another configuration. As another configuration, for example, it is conceivable that the other end of the conductive sheet 40 is fixed to the metal cover 26 by soldering, welding, caulking, or the like.

[0077] The conductive sheets 30, 130, 230 with the metal plates may be electromagnetic shielding members or other members. As other members, for example, in FIG. 1, when a bracket 310 is fixed to the housing 11 in the first electrical device 10 and a bracket 320 is fixed to the housing 15 in the second electrical device 14, it is conceivable that each end of the conductive sheet 340 is fixed to the brackets 310, 320. In this case, the conductive sheet 330 with the metal plate is assumed to be a member used as a current path for grounding that electrically connects the housing 11, which is an example of a grounding portion, and the housing 15, which is an example of a grounding portion.

[0078] In the metal plates 50, 150, 250, they may or may not have fixing portions such as the fixing piece 56. The metal plates 50, 150, 250 may have portions other than the fixing portions, for example, portions that become an electromagnetic shielding case.

[0079] Note that the respective configurations described in the above embodiments and each modification can be appropriately combined as long as they do not contradict each other.
