[0025] Furthermore, multiple technical solutions may sometimes be described in general terms as a single implementation method. Additionally, a portion of the content described below is explained as any constituent element relating to this disclosure.

[0026] Figure 1 This is a perspective view of the housing 100. Figure 2 This is a perspective view of the shell 100 in its disassembled state, shown from the X-side. Figure 3This is a perspective view of the housing 100 in its disassembled state, shown from the X+ side. The housing 100 is made of metal and provides physical and electrical protection to the substrate 200 housed within it. It includes a first member 110, a second member 130, and a first protrusion 114 arranged in the thickness direction (Z-axis direction in the figure) of the substrate 200 housed within it. The metal constituting the housing 100 is not limited; it can be a single metal or an alloy, etc. Furthermore, the housing 100 may also have a protective film, such as a rust-preventive film, formed on its surface through surface treatment or similar methods.

[0027] The substrate 200 includes a printed circuit board with wiring implemented thereon and circuit components such as electronic components and electrical components mounted on the printed circuit board. The type of circuit formed by the circuit components electrically connected through the substrate 200 is not limited, but in this embodiment, it is assumed that the substrate 200 generates noise of a specified frequency.

[0028] The first component 110 is a box-shaped component that covers the substrate 200 on one side (Z-side in the figure) in the thickness direction of the substrate 200, and has a first face 111, a first raised portion 112 and a second raised portion 113.

[0029] The first face 111 is a rectangular portion of the first main face 201 of the cover substrate 200 of the first member 110. The main face refers to the pair of face 200 with the largest area. The rectangular shape means that the first face 111 can be considered rectangular when viewed from the thickness direction of the substrate 200; it may also have partial notches, protrusions, or rounded corners. Covering the first main face 201 includes covering most of the first main face 201 when viewed from the thickness direction of the substrate 200, and also includes covering the entire first main face 201 when viewed from the thickness direction of the substrate 200.

[0030] The first erected portion 112 is a part of a wall-like portion that rises from one end edge (X-side edge) of the first face portion 111 in the short side direction (X-axis direction in the figure). The first erected portion 112 is the portion that contacts the first contact portion 132, which will be described later. In this embodiment, the first erected portion 112 is positioned at a location offset from the center portion in the long side direction (Y-axis direction in the figure) of the first face portion 111.

[0031] The second erected portion 113 is a wall-like portion that rises from the other end edge (X+ side edge in the figure) of the first face portion 111 in the short side direction. In this embodiment, the first erected portion 112 and the second erected portion 113 are arranged orthogonally to the short side direction.

[0032] In this embodiment, the first member 110 includes: a third erected portion 115, which stands upright in the longitudinal direction of the first face portion 111 at a position aligned with the first erected portion 112 and contacts the third contact portion 138 described later; and a fourth erected portion 116, which stands upright in the longitudinal direction opposite to the first erected portion 112 on the side opposite to the third erected portion 115 and contacts the fourth contact portion 139 described later. In this embodiment, the third erected portion 115 and the fourth erected portion 116, like the first erected portion 112, are part of a wall-like portion erected from one end edge of the first face portion 111.

[0033] The second component 130 is a box-shaped component that covers the substrate 200 on the other side (Z+ side in the figure) of the thickness direction of the substrate 200, and has a second surface 131, a first contact portion 132 and a first overlapping portion 133.

[0034] The second surface 131 is a rectangular portion that covers the second main surface 202 disposed on the opposite side of the first main surface 201. Covering the second main surface 202 includes covering most of the second main surface 202 when viewed from the thickness direction of the substrate 200, and also includes covering the entire second main surface 202 when viewed from the thickness direction of the substrate 200.

[0035] The first contact portion 132 is a portion that rises from one end edge of the second face portion 131 in the short side direction and overlaps with the outer surface of the first erected portion 112 of the first member 110 in a contact state. In this embodiment, the first contact portion 132 is a strip-shaped portion disposed at a position offset from the center portion in the long side direction of the second face portion 131.

[0036] In this embodiment, the second member 130 includes a third contact portion 138 that rises from one end edge of the second face portion 131 in the short side direction and overlaps with the outer surface of the third upright portion 115 in a contact state. The second member 130 also includes a fourth contact portion 139 that rises from one end edge of the second face portion 131 in the short side direction and overlaps with the outer surface of the fourth upright portion 116 in a contact state. The fourth upright portion 116 is positioned opposite the third upright portion 115 in the long side direction relative to the first upright portion 112.

[0037] A first connector 211, mounted on the substrate 200, is disposed between the first raised portion 112 and the first contact portion 132 and the third raised portion 115 and the third contact portion 138. Additionally, a second connector 212, mounted on the substrate 200, is disposed between the first raised portion 112 and the first contact portion 132 and the fourth raised portion 116 and the fourth contact portion 139. The first connector 211 and the second connector 212 are components that penetrate the housing 100 from the inside out. The first connector 211 and the second connector 212 are connectors used to obtain communication, power supply, and signals from sensors from the outside of the housing 100. At least one of the first connector 211 and the second connector 212 is electrically connected to the common wiring (ground wiring) of the substrate 200.

[0038] The first overlapping portion 133 is a wall-like portion that rises from the other end edge (X+ side edge in the figure) of the second face 131 in the short side direction and overlaps with the outer surface of the second erected portion 113 with a gap.

[0039] In the short-side direction (X-axis direction in the figure), the first protrusion 114 is disposed between the second upright portion 113 and the first overlapping portion 133, and is used to maintain a predetermined interval between the second upright portion 113 and the first overlapping portion 133. The first protrusion 114 can be installed on either the second upright portion 113 or the first overlapping portion 133. In this embodiment, the first protrusion 114 is integrally provided in a state where it protrudes outward from the second upright portion 113. The shape of the first protrusion 114 is not limited. In this embodiment, the first protrusion 114 is shaped by cutting a cylinder with a plane parallel to the central axis, and the end near the second member 130 is provided with an inclined portion 119 that is closer to the second upright portion 113 the closer it is to the second member 130. The first protrusion 114 maintains a predetermined distance between the second erected portion 113 and the first overlapping portion 133, thereby ensuring close contact between the first erected portion 112 and the first contact portion 132, and generating a predetermined pressure between the first erected portion 112 and the first contact portion 132. This creates a strong fit between the first member 110 and the second member 130 in the short-side direction.

[0040] Figure 4 This is a cross-sectional view of the housing 100 cut along the YZ plane. In this embodiment, the second member 130 includes a second overlapping portion 134, a third overlapping portion 135, a second protrusion 136, and a third protrusion 137.

[0041] The second overlapping portion 134 and the third overlapping portion 135 are wall-shaped portions that stand up from the two end edges of the second surface portion 131 along its long side and overlap with the end edge of the substrate 200 with a predetermined gap. In this embodiment, a portion of each of the second overlapping portion 134 and the third overlapping portion 135 overlaps with the first member 110 along its long side with a predetermined gap.

[0042] The second protrusion 136 and the third protrusion 137 are portions that protrude from the inner surfaces of the second overlapping portion 134 and the third overlapping portion 135 toward the substrate 200. The second protrusion 136 and the third protrusion 137 abut against the end edge of the substrate 200, thereby determining the position of the second member 130 relative to the substrate 200 in the long side direction, and determining the position of the second member 130 relative to the first member 110 by means of the substrate 200. Thus, in the long side direction, a gap is formed between the first member 110 and the second overlapping portion 134 and the third overlapping portion 135, and the first member 110 does not contact the second overlapping portion 134 and the third overlapping portion 135 in the long side direction. In this embodiment, the ends of the second protrusion 136 and the third protrusion 137 on the side near the first member 110 are respectively provided with a first slope portion 141 and a second slope portion 142 that guide the second member 130 along the end edge of the substrate 200.

[0043] The shapes of the second protrusion 136 and the third protrusion 137 are not limited, but in this embodiment, they are semi-cylindrical shapes formed by cutting a cylindrical shape with a surface including the central axis.

[0044] Figure 5 This is a perspective view showing the state in which the substrate 200 is placed on the first member 110. The first member 110 has a plurality of first claw portions 117 and second claw portions 118 protruding toward the second member 130 at predetermined positions. The first claw portions 117 protrude upright from the end edge of the first face portion 111 along its long side. The second claw portions 118 have a crank shape, which is upright toward the second member 130 and then bends inward to be upright toward the second member 130. The substrate 200 has a first notch portion 221 and a second notch portion with shapes corresponding to the first claw portions 117 and the second claw portions 118. When the substrate 200 is placed on the first member 110, the first claw portions 117 engage with the first notch portion 221, and the second claw portions 118 engage with the second notch portion 222. This determines the position of the substrate 200 relative to the first member 110.

[0045] Next, the second member 130 is brought close to the substrate 200 and the first member 110 in a manner that covers the substrate 200 and the first member 110. In the long-side direction, the second member 130 is guided relative to the substrate 200 by the first slope portion 141 and the second slope portion 142, causing the second protrusion 136 and the third protrusion 137 to abut against the end edge of the substrate 200 in the long-side direction. This determines the position of the first member 110, the substrate 200, and the second member 130 in the long-side direction. The tips of the first contact portion 132, the third contact portion 138, and the fourth contact portion 139 are guided by the curved portion of the second claw portion 118 and overlap with the first upright portion 112, the third upright portion 115, and the fourth upright portion 116 respectively in the short-side direction.

[0046] On the other hand, the first overlapping portion 133 is guided by the inclined portion 119 located at the end of the first protrusion 114, thereby increasing the distance between it and the first contact portion 132, the third contact portion 138, and the fourth contact portion 139. Due to the friction between the first contact portion 132, the third contact portion 138, and the fourth contact portion 139 and the first erected portion 112, the third erected portion 115, and the fourth erected portion 116 generated at this time, the highly insulating film existing on the surface of the first member 110 and the second member 130 is peeled off, ensuring electrical contact between the first contact portion 132, the third contact portion 138, and the fourth contact portion 139 and the first erected portion 112, the third erected portion 115, and the fourth erected portion 116.

[0047] With the substrate 200 sandwiched in the thickness direction by the first member 110 and the second member 130, the first member 110 and the second member 130 are fastened in the thickness direction of the substrate 200 by the fastening member 300. Thus, the housing 100 is completed, and an electronic device in which the substrate 200 is housed inside the housing 100 is manufactured.

[0048] In the fastening portion secured by the fastening member 300, the second member 130 is electrically connected to the common wiring (ground wiring) of the substrate 200. Here, even if noise is emitted from the substrate 200 when the distance between the two fastening members 300 arranged along the long side is an integer fraction of the wavelength, the portion of the second member 130 between one fastening member 300 and the other fastening member 300 is blocked from functioning as an antenna because the first contact portion 132 is electrically connected to the first erect portion 112, thus suppressing the emission of noise to the outside of the housing 100.

[0049] Furthermore, since the first protrusion 114 is electrically connected to the first overlapping portion 133, when static electricity is applied to the second member 130 from the outside of the housing 100, in addition to forming a path for static electricity toward the nearby fastening member 300, a path for static electricity toward the connection portion of the first protrusion 114 and the first overlapping portion 133 is also formed, which can efficiently discharge static electricity to the outside of the housing 100.

[0050] In addition, pressure is generated at three locations: the contact portion between the first protrusion 114 and the first overlapping portion 133, the contact portion between the third contact portion 138 and the third upright portion 115, and the contact portion between the fourth contact portion 139 and the fourth upright portion 116, which strongly fits the first member 110 and the second member 130. Therefore, before being fastened based on the fastening member 300, the first member 110 and the second member 130 will not wobble relative to each other, and a strong fit can be created.

[0051] Furthermore, this disclosure is not limited to the embodiments described above. For example, the constituent elements described in this specification can be combined arbitrarily, and other embodiments implemented by removing several constituent elements can also be considered as embodiments of this disclosure. In addition, modifications that can be made to the above embodiments without departing from the spirit of this disclosure, i.e., the meaning of the statements in the claims, are also included in this disclosure.

[0052] For example, the case where the first protrusion 114 is provided on the side of the first member 110 has been described, but the first protrusion 114 may also be provided on the inner surface of the first overlapping portion 133 of the second member 130. Alternatively, the first protrusion 114 may be provided on both the first member 110 and the second member 130.

[0053] In addition, the case where a connector is provided through the housing 100 is described, but the substrate 200 may not have a connector.

[0054] Alternatively, it could be an electronic device that includes a housing 100 and a substrate 200. Examples of electronic devices include an ECU (Electronic Control Unit) that can electronically control all or part of the functions of the mobile body 220, an audio amplifier, an active noise controller, an active sound controller, etc.

[0055] In addition, such as Figure 6 As shown, it can also be implemented as a mobile body 220 having a housing 100. Examples of mobile bodies 220 include automobiles, airplanes, and ships.

[0056] (Summarize)

[0057] The first type of housing 100 is a metal housing 100 for housing the substrate 200. The housing 100 includes a first member 110 and a second member 130 arranged in the thickness direction of the substrate 200. The first member 110 includes: a rectangular first surface 111 that covers a first main surface 201 of the substrate 200; a first raised portion 112 that rises from one end edge of the first surface 111 in the short side direction; and a second raised portion 113 that rises from the other end edge of the first surface 111 in the short side direction. The second member 130 includes: a rectangular second surface 131 that covers the first main surface 201. On the opposite side, there is a second main surface 202; a first contact portion 132, which stands up from one end edge of the second surface portion 131 in the short side direction and overlaps with the outer surface of the first erect portion 112 in a contact state; and a first overlapping portion 133, which stands up from the other end edge of the second surface portion 131 in the short side direction and overlaps with the outer surface of the second erect portion 113 with a gap, at least one of the second erect portion 113 and the first overlapping portion 133 having a first protrusion 114, which maintains the gap between the second erect portion 113 and the first overlapping portion 133 at a predetermined distance, thereby generating pressure between the first erect portion 112 and the first contact portion 132.

[0058] According to the first method, the phenomenon that noise of a predetermined frequency emitted from the housed substrate 200 is emitted to the outside through the housing 100 which functions as an antenna can be suppressed by changing the antenna length by electrically connecting the first erected portion 112 to the first contact portion 132.

[0059] In addition, the first member 110 and the second member 130 are connected via a first protrusion 114 disposed on the opposite side of the first erected portion 112, thereby increasing the path for releasing static electricity applied from the outside and enabling efficient discharge of static electricity.

[0060] The second type of housing 100 includes the first type, wherein the second member 130 has a second overlapping portion 134 and a third overlapping portion 135. The second overlapping portion 134 and the third overlapping portion 135 stand up from the long side direction of the second surface portion 131 at both ends of the second surface portion 131 and overlap with the end edge of the substrate 200 with a gap. The second overlapping portion 134 has a second protrusion 136 that protrudes toward the substrate 200 and abuts against the end edge of the substrate 200. The third overlapping portion 135 has a third protrusion 137 that protrudes toward the substrate 200 and abuts against the end edge of the substrate 200.

[0061] According to the second method, the positional relationship between the first member 110 and the second member 130 can be determined by means of the substrate 200 in the long side direction. Therefore, contact between the first member 110 and the second member 130 in the long side direction can be avoided, and the effect of electrical connection between the first erected portion 112 and the first contact portion 132 and the effect of the first protrusion 114 can be maintained, preventing these effects from being reduced.

[0062] The third type of housing 100 includes either the first type or the second type, wherein the first upright portion 112 and the first contact portion 132 are disposed at the central portion in the long side direction away from the second face portion 131.

[0063] According to the third method, it is possible to avoid placing the connection position between the first erected portion 112 and the first contact portion 132 in the center, which would result in a length of one-quarter wavelength of noise emitted from the substrate 200 at a predetermined frequency, thereby suppressing the amount of noise leaking to the outside.

[0064] The fourth type of housing 100 includes any one of the first to third types. The first member 110 includes: a third erected portion 115, which is erected in the long side direction of the first face 111 at a position arranged with the first erected portion 112; and a fourth erected portion 116, which is erected in the long side direction at a position opposite to the first erected portion 112 on the third erected portion 115. The second member 130 includes: a third contact portion 138, which overlaps with the outer surface of the third erected portion 115 in a contact state; and a fourth contact portion 139, which overlaps with the outer surface of the fourth erected portion 116 in a contact state.

[0065] According to the fourth method, a strong fitting state is created by at least three parts: the connection between the third erection 115 and the third contact 138, the connection between the fourth erection 116 and the fourth contact 139, and the position of the first protrusion 114. Therefore, the relative wobbling of the first member 110 and the second member 130 before the first member 110 and the second member 130 are connected can be suppressed.

[0066] The housing 100 of the fifth type includes the fourth type, wherein a first connector 211 mounted on the substrate 200 is disposed between the first erected portion 112 and the third erected portion 115, and a second connector 212 mounted on the substrate 200 is disposed between the first erected portion 112 and the fourth erected portion 116.

[0067] According to the fifth method, the reduction in rigidity of the housing 100 caused by the large hole through which the first connector 211 and the second connector 212 pass can be suppressed by the connection portions provided at both ends of the large hole.

[0068] The sixth type of electronic device includes a substrate 200 and a metal housing 100 for housing the substrate 200. The housing 100 includes a first member 110 and a second member 130 arranged in the thickness direction of the substrate 200. The first member 110 includes: a rectangular first surface 111 covering a first main surface 201 of the substrate 200; a first erected portion 112 erected from one end edge of the first surface 111 in the short side direction; and a second erected portion 113 erected from the other end edge of the first surface 111 in the short side direction. The second member 130 includes: a rectangular second surface 131 covering the first main surface 201. The second main surface 202 on the opposite side of 01; a first contact portion 132, which stands up from one end edge of the second face portion 131 in the short side direction and overlaps with the outer surface of the first standing portion 112 in a contact state; and a first overlapping portion 133, which stands up from the other end edge of the second face portion 131 in the short side direction and overlaps with the outer surface of the second standing portion 113 with a gap, at least one of the second standing portion 113 and the first overlapping portion 133 having a first protrusion 114, which maintains the gap between the second standing portion 113 and the first overlapping portion 133 at a predetermined distance, so that pressure is generated between the first standing portion 112 and the first contact portion 132.

[0069] The seventh type of mobile body 220 is a mobile body 220 of an electronic device having a substrate 200 and a metal housing 100 for housing the substrate 200. The housing 100 includes a first member 110 and a second member 130 arranged in the thickness direction of the substrate 200.
