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

[0011] The conductive sheet with a metal plate of this disclosure is as follows:

[0012] (1) A conductive sheet with a metal plate, comprising a conductive sheet, a metal plate, and a sheet fixing member separate from the metal plate, wherein a portion of the conductive sheet is sandwiched between the metal plate and the sheet fixing member, the sheet fixing member is superimposed on the metal plate and fixed, a positioning recess is formed on one of the metal plate and the sheet fixing member, and a positioning projection is formed on the other which contacts the edge of the positioning recess to be positioned. According to this disclosure, the sheet fixing member is superimposed on the metal plate with the positioning projection in contact with the edge of the positioning recess to be positioned. Therefore, the metal plate sandwiching the conductive sheet and the sheet fixing member can be easily positioned.

[0013] (2) A conductive sheet with a metal plate as in (1), wherein the conductive sheet may be in contact with the positioning projection. The conductive sheet is also positioned with respect to the positioning projection.

[0015] (4) A conductive sheet with a metal plate, one of the metal plates from (1) to (3), wherein the positioning recess includes a positioning hole surrounded by a border, and the positioning projection may be fitted into the positioning hole. Because the positioning projection is fitted into the positioning hole, the sheet fixing member is positioned more reliably with respect to the metal plate.

[0016] (5) A conductive sheet with a metal plate, one of the metal plates from (1) to (4), wherein the positioning recess includes a positioning notch portion which is partially surrounded by an edge, and the positioning protrusion may be in contact with the edge of 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 is 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 the front and back, the front and back can be easily distinguished 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.

[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. Note that the present disclosure is not limited to these examples, and is intended to be defined by the claims and 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, for example, a vehicle or the like. Examples of the combination of the two electrical devices 10 and 14 include 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] A wiring member 20 is connected to at least one of two electrical devices 10 and 14. Figure 1 shows one end of the wiring member 20 connected to the first electrical device 10. In this embodiment, the wiring member 20 is a component for connecting the first electrical device 10 to other electrical devices, etc. The other end of the wiring member 20 may be connected to the second electrical device 14, or to other electrical devices.

[0023] The wiring member 20 comprises a transmission member 22 and a connection part 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 also be a member in which multiple insulated wires are bundled together. The transmission member may also be configured in which multiple linear conductors are embedded in a single insulating portion while being insulated from each other.

[0025] A connection portion 24 is provided at one end of the transmission member 22. The connection portion 24 is a component 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 component comprising a terminal and a housing that holds the terminal. With the housing of the connection portion 24 attached to the housing 11 by a snap-fit ​​structure, a screw-fastening structure, etc., the terminal held by the housing is kept connected to the electrical component in the first electrical device 10.

[0026] The above-mentioned connection portion 24 is covered by a metal cover 26. The metal cover 26 is a component formed by pressing or otherwise processing a metal plate such as copper, copper alloy, aluminum, or aluminum alloy. The metal cover 26 is formed on the surface of the housing 11 to cover the portion of the connection portion 24 other than the portion in which the transmission member 22 extends. The metal cover 26 is fixed to the housing 11 by screws or the like. This metal cover 26 can serve to electromagnetically shield the end of the transmission member 22 from the connection portion 24.

[0027] The conductive sheet 30 with a metal plate is an electromagnetic shielding member that covers at least a portion of the wiring member 20. Here, the conductive sheet 30 with a metal plate comprises a conductive sheet 40, a metal plate 50, and a sheet fixing member 60 which 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 equipment 14. The other end of the conductive sheet 40 is fixed to the metal cover 26. Therefore, the conductive sheet 40 is supported in a fixed position so as to span between the metal cover 26 fixed to the first electrical equipment 10 and the housing 15 of the second electrical equipment 14.

[0028] The wiring member 20 extends on the side closer to the housing 11 than the conductive sheet 40, and in the same direction as the conductive sheet 40 extending from the connection portion 24. Therefore, at least the end of the wiring member 20 on the side of the first electrical equipment 10 is covered by the conductive sheet 40. In this respect, 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] The following description will focus on the configuration in which one end of the conductive sheet 40 is fixed to the metal plate 50 and the sheet fixing member 60. Figure 2 is a perspective view showing the conductive sheet 30 with the metal plate. Figure 3 is an exploded perspective view of the conductive sheet 30 with the metal plate. Figure 4 is a partial cross-sectional view taken along line IV-IV in Figure 2.

[0030] The conductive sheet 40 is a conductive member formed in sheet form. The conductive sheet 40 is formed, for example, from braided metal wires. Braided metal wires include braids, metal cloth, metal mesh, etc. The conductive sheet 40 is formed in a rectangular shape. A metal plate 50 and a sheet fixing member 60 are fixed to one end of the conductive sheet 40. The length of the conductive sheet 40 is, for example, large enough to be installed across the first electrical equipment 10 and the second electrical equipment 14. The width of the conductive sheet 40 is, for example, large enough to cover the transmission member 22 from the side opposite the first electrical equipment 10.

[0031] The metal plate 50 and the sheet fixing member 60 are components that maintain the conductive sheet 40 in a state where it covers a portion of the wiring member 20. Here, the metal plate 50 and the sheet fixing member 60, together with the metal cover 26, maintain the conductive sheet 40 in a state where it covers a portion of the wiring member 20.

[0032] The metal plate 50 is a component formed by pressing or otherwise processing a metal plate such as copper, copper alloy, aluminum, or aluminum alloy. The metal plate 50 comprises a clamping and fixing body portion 52 and a fixing piece 56.

[0033] The clamping and fixing body portion 52 is formed in the shape of a rectangular plate, or more specifically, an elongated rectangular plate. The longitudinal dimension of the clamping and fixing 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 to extend outward from the outer circumference of the clamping fixing body portion 52. Here, the fixing piece 56 is formed to extend outward from one of the long sides of the clamping fixing body portion 52. The direction in which the fixing piece 56 extends is a direction that avoids the direction in which the conductive sheet 40 extends from the clamping fixing body portion 52. Here, the fixing piece 56 extends in the opposite direction to the direction in which the conductive sheet 40 extends relative to the clamping fixing body portion 52. The fixing piece 56 is the part that is fixed to the part to be fixed, such as the housing 15. In this embodiment, a screw insertion hole 56h is formed in the fixing piece 56. With the screw S inserted through the screw insertion hole 56h, the screw S is screwed into the screw groove formed in the housing 15. This fixes the fixing piece 56 to the housing 15. The fixing piece 56 may also be fixed to the housing 15 by other means, such as welding, riveting, or crimping.

[0035] The fixing piece 56 is bent relative to the clamping fixing body 52 toward one main surface side of the clamping fixing body 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 clamping fixing body 52 is bent. However, the fixing piece 56 may extend without bending relative to the clamping fixing body 52.

[0036] The sheet fixing member 60 is a separate component from the metal plate 50. With one end of the conductive sheet 40 sandwiched between the metal plate 50 and the sheet fixing member 60, the sheet fixing member 60 is superimposed on the metal plate 50 and fixed in place.

[0037] The sheet fixing member 60 can be any member that can be superimposed 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, or aluminum alloy, or it may be a resin.

[0038] In this embodiment, the sheet fixing member 60 is made of a metal plate such as copper, copper alloy, aluminum, or aluminum alloy. Here, the sheet fixing member 60 is formed in the shape of a rectangular plate, or more specifically, an elongated rectangular plate. 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. The sheet fixing member 60 may also have fixing pieces or the like integrally formed for fixing to the part to be fixed.

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

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

[0041] More specifically, a positioning recess 54 is formed in the part of the clamping and fixing body portion 52 of the metal plate 50 that is closer to the fixing piece 56. There may be one or more positioning recesses 54. In this embodiment, multiple (two in this case) positioning recesses 54 are formed at intervals along the longitudinal direction of the clamping and fixing body portion 52.

[0042] The positioning recess 54 only needs to be a recess that can restrict the position of the positioning projection 62 in at least one direction by contacting the positioning projection 62. Here, an example is described in which the positioning recess 54 is a positioning hole surrounded by an edge. The positioning recess 54 may not be a positioning hole, but a recess that is partially surrounded by an edge and the rest is open. Modifications of this case will be described later with reference to Figure 5 or Figure 6. In this embodiment, the positioning recess 54 as a positioning hole is a hole that penetrates the metal plate 50. However, the positioning recess 54 as a positioning hole does not need to penetrate the metal plate 50 and may be a bottomed hole. Also, the opening shape of the positioning recess 54 is not particularly limited. In this embodiment, the positioning recess 54 is formed in the shape of a rectangular hole. The opening shape of the positioning recess 54 may also be a circular shape, an elliptical shape, a slit shape, a triangular shape, or other polygonal shapes.

[0043] The positioning projection 62 is formed on one of the long sides of the sheet fixing member 60. There may be one or more positioning projections 62. In this embodiment, corresponding to the multiple positioning recesses 54, multiple (two in this case) positioning projections 62 are formed at intervals along one of the long sides of the sheet fixing member 60. The spacing between the multiple positioning recesses 54 is the same as the spacing between the multiple positioning projections 62.

[0044] The positioning projection 62 is formed by extending a strip-shaped portion from a part of one of the long sides of the sheet fixing member 60 and bending this extended portion toward one of the main surfaces of the sheet fixing member 60. More specifically, a partial recess 61 is formed on one of the long sides of the sheet fixing member 60. A strip-shaped portion extends from the back of this recess 61. The positioning projection 62 is formed by bending this strip-shaped portion toward one of the main surfaces of the sheet fixing member 60. The positioning projection 62 protrudes beyond one of the main surfaces of the sheet fixing member 60.

[0045] The width dimension of the positioning projection 62 may be smaller than the width dimension of the recess 61. Also, the inward-facing surface 62f of the positioning projection 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 opposite side from the metal plate 50, a gap 61s is formed on the outside of the positioning projection 62.

[0046] Then, with the sheet fixing member 60 superimposed on the metal plate 50, the positioning projection 62 is fitted into the positioning recess 54 (see arrow P2 in Figure 3). At this time, the positioning projection 62 is positioned by contacting one of the edges around the positioning recess 54. As a result, the sheet fixing member 60 is positioned relative to the metal plate 50. At this time, the rotation of the sheet fixing member 60 relative to the metal plate 50 is restricted as multiple positioning projections 62 are positioned in multiple positioning recesses 54.

[0047] With the sheet fixing member 60 superimposed on the metal plate 50, one end 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 of the conductive sheet 40 aligned with the longitudinal direction of the clamping fixing body portion 52 on the metal plate 50 and the sheet fixing member 60 (see arrow P1 in Figure 3), one end of the conductive sheet 40 is sandwiched between the metal plate 50 and the sheet fixing member 60.

[0048] In this case, the conductive sheet 40 may be in contact with the positioning protrusions 62. Here, the edge of one end of the conductive sheet 40 is in contact with the inner portion of the multiple positioning protrusions 62. As a result, the conductive sheet 40 is sandwiched in a fixed position between 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 (i.e., the side on which the positioning projection 62 is formed), a window is formed adjacent to the positioning projection 62, allowing the edge of the conductive sheet 40 in contact with the positioning projection 62 to be visible. Here, the gap 61s is formed as a window on the outside of the positioning projection 62. By checking whether the edge of one end of the conductive sheet 40 can be seen through the gap 61s, it is possible to confirm whether the edge of one end of the conductive sheet 40 is in a predetermined position in contact with the inner portion of the multiple positioning projections 62.

[0050] The metal plate 50 and the sheet fixing member 60 are fixed in an overlapping state. In this embodiment, the metal plate 50 and the sheet fixing member 60 are fixed by a mechanical clinch portion 70. Here, a mechanical clinch refers to a mechanical fitting structure between a convex portion formed on one of the two metal plates and a concave portion formed on the other, thereby keeping the two metal plates in an overlapping state. The mechanical clinch portion 70 is the fitting structure portion between such a convex portion 72 and a concave portion 74.

[0051] In the examples shown in Figures 2 and 4, a protrusion 72 is formed on the sheet fixing member 60, and a recess 74 is formed on the metal plate 50. The protrusion 72 is fitted into the recess 74, keeping the sheet fixing member 60 superimposed on the metal plate 50. The relationship between the protrusion and recess between the sheet fixing member 60 and the metal plate 50 may be reversed.

[0052] The mechanical clinch portion 70 described above can be formed, for example, by pressing the metal plate 50 and the sheet fixing member 60 together to partially plastically deform the metal plate 50 and the sheet fixing member 60. Alternatively, during or after the pressing process, the base end portion of the convex portion 72 and the opening portion of the recess 74 may be plastically deformed to narrow them. In this case, the tip portion of the convex portion 72 will be wider than its base end portion, and the back portion of the recess 74 will be wider than its opening portion. This makes it difficult for the convex portion 72 to come out of the recess 74.

[0053] The mechanical clinch portion 70 is required to keep the metal plate 50 and the sheet fixing member 60 in an overlapping state. The position and number of mechanical clinch portions 70 in the overlapping portion of the metal plate 50 and the sheet fixing member 60 are arbitrary. For example, one mechanical clinch portion may be formed in the longitudinal center of the sheet fixing member 60. Alternatively, for example, a pair of mechanical clinch portions may be formed at both longitudinal ends of the sheet fixing member 60. In this embodiment, an example is shown in which multiple (five in this case) mechanical clinch portions 70 are formed at intervals along the longitudinal direction of the sheet fixing member 60.

[0054] In this embodiment, the mechanical clinch portion 70 is located in a region where the metal plate 50 and the sheet fixing member 60 sandwich a portion of the conductive sheet 40. Therefore, in the mechanical clinch portion 70, the conductive sheet 40 is sandwiched between the convex portion 72 and the concave portion 74 of the mechanical clinch portion 70. Furthermore, the conductive sheet 40 is strongly sandwiched between the metal plate 50 and the sheet fixing member 60 around the mechanical clinch portion 70. Note that the position of the mechanical clinch portion 70 relative to the area where the conductive sheet 40 is installed is arbitrary. For example, part or all of the mechanical clinch portion may be located outside the region where the metal plate 50 and the sheet fixing member 60 sandwich a portion of the conductive sheet 40.

[0055] The metal plate 50 and the sheet fixing member 60 may be fixed in an overlapping state by a configuration other than the mechanical clinch part 70. For example, the metal plate 50 and the sheet fixing member 60 may be fixed in an overlapping state by welding, crimping, soldering, screwing, etc.

[0056] With the conductive sheet 30 with a metal plate configured in this way, the positioning projection 62 contacts the edge of the positioning recess 54 and is positioned, and the sheet fixing member 60 is placed on top of the metal plate 50. Therefore, the metal plate 50 that sandwiches the conductive sheet 40 and the sheet fixing member 60 are easily positioned. Then, one end of the conductive sheet 40 is sandwiched and fixed between the precisely positioned metal plate 50 and the sheet fixing member 60, so that a conductive sheet 30 with a metal plate of stable quality can be manufactured.

[0057] Furthermore, with the conductive sheet 40 in contact with the positioning projection 62, the conductive sheet 40 is sandwiched between the metal plate 50 and the sheet fixing member 60. As a result, the amount of clamping of the conductive sheet 40 by the metal plate 50 and the sheet fixing member 60 is stable, and the fixing state of the conductive sheet 40 to the metal plate 50 and the sheet fixing member 60 is stable.

[0058] Furthermore, the positioning recess 54 is formed as a positioning hole surrounded by an edge. As a result, the positioning projection 62 is positioned in all directions within the positioning recess 54. This ensures that the sheet fixing member 60 is positioned more reliably on the metal plate 50.

[0059] Furthermore, a positioning recess 54 is formed on the metal plate 50, and a positioning projection 62 is formed on the sheet fixing member 60. Here, the metal plate 50 has a shape formed on it that performs other functions, such as a fixing piece 56, and it is thought that the front and back sides can be easily distinguished. In contrast, the sheet fixing member 60 is a member solely for fixing the conductive sheet 40, so it is thought that it has a simple shape. Here, the sheet fixing member 60 is an elongated rectangular plate, so it can be observed as having a similar shape from any side. However, upon closer inspection of the sheet fixing member 60, the front and back sides can sometimes be distinguished by the presence or absence of surface processing on the two sides, differences in roughness, the presence or absence of burrs on the edges due to press processing, etc. Therefore, if a positioning projection 62 is formed on the sheet fixing member 60, the front and back sides of the sheet fixing member 60 can be distinguished using the direction of protrusion of the positioning projection 62 as a clue.

[0060] For example, the positioning projection 62 can be made to protrude on the side opposite to the surface where burrs are generated by the press working process. This makes it less likely for burrs to come into contact with the conductive sheet 40 when the sheet fixing member 60 is superimposed on the metal plate 50.

[0061] Furthermore, the metal plate 50 and the sheet fixing member 60 are fixed in an overlapping state by the mechanical clinch section 70. Therefore, the metal plate 50 and the sheet fixing member 60 can be easily fixed by pressing or other methods. In particular, the workability of fixing is better compared to configurations that use other fixing parts such as rivets or screws for fixing.

[0062] [Differentiation] A modified example will be described. Figure 5 is a perspective view showing a conductive sheet 130 with a metal plate according to the first modified example. The conductive sheet 130 with a metal plate comprises 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 of the extending direction of both edges of the metal plate 150. The positioning recesses 154 are formed in a shape that is partially recessed in a rectangular shape from the edge of the metal plate 150. These positioning recesses 154 are formed in a shape that is surrounded on three sides by the edge and opens outwards on the remaining side. Such a positioning recess 154 is an example of a positioning notch that is partially surrounded by the edge. Fixing pieces for fixing to the part to be fixed may be integrally formed on the metal plate 150.

[0064] The sheet fixing member 160 is formed from a metal plate into an elongated plate shape. Positioning protrusions 162 are formed at the midpoint of the extending direction of both edges of the sheet fixing member 160. The positioning protrusions 162 project from the edge of the sheet fixing member 160 toward one side of the sheet fixing member 160. Here, they are formed by extending a part of both side edges of the sheet fixing member 160 into a strip shape and bending this strip-shaped portion toward one side of the sheet fixing member 160. Then, with the positioning protrusions 162 in contact with the three edges of the positioning recess 154, the sheet fixing member 160 is superimposed on the metal plate 150. As a result, the sheet fixing member 160 is accurately positioned relative to the metal plate 150. In particular, the two positioning protrusions 162 are fitted into the positioning recess 154, thereby positioning the metal plate 150 and the sheet fixing member 160 relative to each other in the short-side direction of the metal plate 150. Furthermore, at each of the longitudinal ends of the metal plate 150, the positioning protrusions 162 fit into the positioning recesses 154, thereby positioning the metal plate 150 and the sheet fixing member 160 relative to each other in the longitudinal direction of the metal plate 150. In this state, the metal plate 150 and the sheet fixing member 160 are fixed together by the 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. Inspection windows 150h and 160h are formed on the long side edges of the metal plate 150 and the sheet fixing member 160, on the edge opposite to the side from which the conductive sheet 40 extends. Multiple inspection windows 150h and 160h are formed at intervals along each edge. The inspection windows 150h and 160h are formed in a rectangular shape that is recessed inward from a part of the long side edge 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 such that the edge of one end of the conductive sheet 40 reaches the inspection windows 150h and 160h. By checking for the presence or absence of an edge at one end of the conductive sheet 40 through the inspection windows 150h and 160h, the state in which the conductive sheet 40 is sandwiched between the metal plate 150 and the sheet fixing member 160 can be confirmed.

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

[0067] Figure 6 is a perspective view showing a conductive sheet 230 with a metal plate according to a second modified example. The conductive sheet 230 with a metal plate comprises 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 protrusions 254 are formed on the inside of both edges of the metal plate 250. The positioning protrusions 254 are formed to protrude from one side of the metal plate 250. Here, the positioning protrusions 254 are formed by forming a straight slit inside of both edges of the metal plate 250 and bending the portion outside the slit.

[0069] Furthermore, a protrusion 256 is also formed on the inside of one of the long edges of the metal plate 250. The protrusion 256 is formed in a shape that protrudes from one side of the metal plate 250. Here, the protrusion 256 is formed by creating a straight slit inside the long edge of the metal plate 250 and bending the portion outside the slit. In this case, two protrusions 256 are formed at intervals on the inside of one of the long edges of the metal plate 250.

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

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

[0072] Then, with the positioning projection 254 in contact with the three edges of the positioning recess 262, the sheet fixing member 260 is superimposed on the metal plate 250. As a result, similar to the first modified example 1, the sheet fixing member 260 is accurately positioned relative to the metal plate 250. In this state, the metal plate 250 and the sheet fixing member 260 are fixed together by the mechanical clinch portion 270, which corresponds 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 superimposed, the protrusion 256 is positioned within the recess 264 at a location away from the back of the recess 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 protrusion 256. Therefore, the protrusion 256 can be used as a positioning part for the conductive sheet 40, allowing the conductive sheet 40 to 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 protrusion 256, the edge of one end of the conductive sheet 40 can be seen between the back of the recess 264 and the protrusion 256. Therefore, by checking for the presence or absence of an edge of one end of the conductive sheet 40 between the back of the recess 264 and the protrusion 256, it can be confirmed whether or not the end of the conductive sheet 40 is sandwiched in the predetermined position.

[0074] Furthermore, both sides of the protrusion 256 are in contact with both side edges of the recess 264, and in this respect, the protrusion 256 may be considered an example of a positioning protrusion, and the recess 264 may be considered an example of a positioning recess.

[0075] In this modified example 2 as well, since a portion of the area around the positioning recess 262 is open, it is easy to move the positioning projection 254 toward the positioning recess 262 while checking the positional relationship between the positioning projection 254 and the positioning recess 262, and the positioning projection 254 can be easily positioned by the positioning recess 262.

[0076] The mounting structure between the other end of the conductive sheet 40 and the metal cover 26 may be the same as the configuration described in the above embodiment or each of the modified examples, or it may be a different configuration. As an alternative configuration, for example, the other end of the conductive sheet 40 may be fixed to the metal cover 26 by soldering, welding, crimping, or the like.

[0077] The conductive sheets 30, 130, and 230 with metal plates described above may be electromagnetic shielding members or other members. As an example of other members, in Figure 1, when a bracket 310 is fixed to the housing 11 of the first electrical equipment 10 and a bracket 320 is fixed to the housing 15 of the second electrical equipment 14, it is conceivable that the ends of the conductive sheet 340 are fixed to the brackets 310 and 320. In this case, it is assumed that the conductive sheet 330 with metal plates is a member used as an earth current path to electrically connect the housing 11, which is an example of an earth location, and the housing 15, which is another example of an earth location.

[0078] The metal plates 50, 150, and 250 described above may or may not have fixing parts such as fixing pieces 56. The metal plates 50, 150, and 250 may also have parts other than the fixing parts, for example, parts that form an electromagnetic shield case.

[0079] Furthermore, the configurations described in the above embodiments and each of the modified examples can be combined as appropriate, as long as they do not contradict each other. [Explanation of symbols]
