[Modes for carrying out the invention]

[0011] The embodiments of the housing, electronic equipment, and mobile body relating to this disclosure will be described below with reference to the drawings. The following embodiments are provided as examples to illustrate this disclosure and are not intended to limit it. For example, the shapes, structures, materials, components, relative positional relationships, connection states, numerical values, formulas, the content of each step in the method, and the order of each step shown in the following embodiments are examples and may include content not described below. Geometric expressions such as parallel and orthogonal may be used, but these expressions do not indicate mathematical rigor and include substantially acceptable errors and deviations. Similarly, expressions such as simultaneous and identical also include substantially acceptable ranges.

[0012] Furthermore, the drawings are schematic diagrams that have been appropriately emphasized, omitted, or had their proportions adjusted to illustrate this disclosure, and do not represent the actual shapes, positions, or proportions. Also, the X, Y, and Z axes shown in the drawings represent orthogonal coordinates arbitrarily set for the purpose of illustrating the drawings. In other words, the Z axis is not necessarily an axis along the vertical direction, and the X and Y axes are not necessarily located in the horizontal plane.

[0013] Furthermore, in the following, multiple inventions may be described comprehensively as a single embodiment. Also, some of the content described below is described as an optional component relating to this disclosure.

[0014] Figure 1 is a perspective view showing the housing 100. Figure 2 is a perspective view showing the disassembled housing 100 from the X- side. Figure 3 is a perspective view showing the disassembled housing 100 from the X+ side. The housing 100 is made of metal and physically and electrically protects the substrate 200 housed inside, and comprises a first member 110, a second member 130, and a first protrusion 114, all aligned in the thickness direction (Z-axis direction in the figure) of the substrate 200 housed inside. The metal constituting the housing 100 is not limited and may be a single metal or an alloy. The housing 100 may also have a protective film on its surface, such as a rust-preventive film formed by surface treatment.

[0015] The substrate 200 includes a printed circuit board with wiring 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 by the substrate 200 is not limited. However, in the case of this embodiment, it is assumed that the substrate 200 generates noise at a predetermined frequency.

[0016] The first member 110 is a box-shaped member that covers the substrate 200 on one side (Z− side in the figure) in the thickness direction of the substrate 200 to be accommodated, and includes a first surface portion 111, a first standing portion 112, and a second standing portion 113.

[0017] The first surface portion 111 is a rectangular portion that covers the first main surface 201 of the substrate 200 in the first member 110. The main surface means a pair of surfaces of the plate-shaped substrate 200 having the largest area. The rectangular shape is a shape that can be regarded as a rectangle when the first surface portion 111 is viewed from the thickness direction of the substrate 200, and there may be cutouts, protrusions, etc. in part, and the corners may be rounded. Covering the first main surface 201 includes cases where most of the first main surface 201 is covered and cases where the entire first main surface 201 is covered when viewed from the thickness direction of the substrate 200.

[0018] The first standing portion 112 is a part of a wall-shaped portion that rises from one end edge (X− side edge in the figure) of the first surface portion 111 in the short side direction (X-axis direction in the figure) of the first surface portion 111. The first standing portion 112 is a portion that contacts a first contact portion 132 described later. In the case of this embodiment, the first standing portion 112 is arranged at a position shifted from the central portion in the longitudinal direction (Y-axis direction in the figure) of the first surface portion 111.

[0019] The second standing portion 113 is a wall-shaped portion that rises from the other end edge (X+ side edge in the figure) of the first surface portion 111 in the short side direction. In the case of this embodiment, the first standing portion 112 and the second standing portion 113 are arranged so as to be orthogonal to each other in the short side direction.

[0020] In this embodiment, the first member 110 includes a third upright portion 115 that rises in the longitudinal direction of the first surface portion 111 at a position adjacent to the first upright portion 112 and contacts a third contact portion 138, which will be described later, and a fourth upright portion 116 that rises in the longitudinal direction at a position opposite to the third upright portion 115 relative to the first upright portion 112 and contacts a fourth contact portion 139, which will be described later. In this embodiment, the third upright portion 115 and the fourth upright portion 116 are part of a wall-like portion that rises from one end edge of the first surface portion 111, similar to the first upright portion 112.

[0021] The second member 130 is a box-shaped member that covers the substrate 200 on the other side (Z+ side in the figure) in the thickness direction of the substrate 200 to be housed, and comprises a second surface portion 131, a first contact portion 132, and a first overlapping portion 133.

[0022] The second surface portion 131 is a rectangular portion that covers the second main surface 202, which is located on the opposite side of the first main surface 201. Covering the second main surface 202 includes cases where most of the second main surface 202 is covered when viewed from the thickness direction of the substrate 200, and cases where the entire second main surface 202 is covered.

[0023] The first contact portion 132 is a portion that rises from one end edge of the second surface portion 131 in the short direction and overlaps with the outer surface of the first upright portion 112 of the first member 110 in a contact state. In this embodiment, the first contact portion 132 is a strip-shaped portion positioned offset from the center of the second surface portion 131 in the longitudinal direction.

[0024] In this embodiment, the second member 130 has a third contact portion 138 that rises from one end edge of the second surface portion 131 in the short direction and overlaps with the outer surface of the third upright portion 115 in contact with it. The second member 130 also has a fourth contact portion 139 that rises from one end edge of the second surface portion 131 in the short direction and overlaps with the outer surface of the fourth upright portion 116 in contact with it. The fourth upright portion 116 is positioned in the longitudinal direction opposite to the third upright portion 115 relative to the first upright portion 112.

[0025] A first connector 211, mounted on the substrate 200, is positioned between the contacting first upright portion 112 and first contact portion 132 and the contacting third upright portion 115 and third contact portion 138. A second connector 212, also mounted on the substrate 200, is positioned between the contacting first upright portion 112 and first contact portion 132 and the upright fourth upright portion 116 and 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 for communication from outside the housing 100, power supply, and acquisition of signals from sensors. 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.

[0026] 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 surface portion 131 in the shorter direction and overlaps with the outer surface of the second upright portion 113 with a gap between them.

[0027] In the short direction (X-axis direction in the figure), the first projection 114 is positioned between the second upright portion 113 and the first overlapping portion 133, and is a portion that maintains a predetermined distance between the second upright portion 113 and the first overlapping portion 133. The first projection 114 may be attached to either the second upright portion 113 or the first overlapping portion 133. In this embodiment, the first projection 114 is integrally provided in a state that protrudes outward from the first overlapping portion 133. The shape of the first projection 114 is not limited. In this embodiment, the first projection 114 is shaped like a cylinder cut by a plane parallel to the central axis, and the end closer to the second member 130 is provided with an inclined portion 119 that approaches the second upright portion 113 as it gets closer to the second member 130. The first protruding portion 114 maintains a predetermined distance between the second upright portion 113 and the first overlapping portion 133, thereby bringing the first upright portion 112 and the first contact portion 132 into close contact and generating a predetermined pressure between the first upright portion 112 and the first contact portion 132. As a result, a tightly fitted state is created between the first member 110 and the second member 130 in the shorter direction.

[0028] Figure 4 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.

[0029] The second overlapping portion 134 and the third overlapping portion 135 are wall-like portions that rise from both ends of the second surface portion 131 in the longitudinal direction of the second surface portion 131, respectively, and overlap with the edges of the substrate 200 with a predetermined gap between them. In this embodiment, the second overlapping portion 134 and the third overlapping portion 135 partially overlap the first member 110 in the longitudinal direction with a predetermined gap between them.

[0030] The second protrusion 136 and the third protrusion 137 are portions that protrude toward the substrate 200 from the inner surfaces of the second overlapping portion 134 and the third overlapping portion 135, respectively. By abutting against the edge of the substrate 200, the second protrusion 136 and the third protrusion 137 determine the position of the second member 130 relative to the substrate 200 in the longitudinal direction of the substrate 200, and determine the position of the second member 130 relative to the first member 110 via the substrate 200. As a result, a gap is formed between the first member 110 and the second overlapping portion 134 and the third overlapping portion 135 in the longitudinal direction, so that the first member 110 and the second overlapping portion 134 and the third overlapping portion 135 do not come into contact in the longitudinal direction. In this embodiment, the ends of the second protrusion 136 and the third protrusion 137 on the first member 110 side are provided with a first tapered portion 141 and a second tapered portion 142, respectively, which guide the third member 133 along the edge of the substrate 200.

[0031] The shapes of the second projection 136 and the third projection 137 are not limited, but in this embodiment they are semi-cylindrical in shape, obtained by cutting a cylindrical shape with a plane including the central axis.

[0032] Figure 5 is a perspective view showing the substrate 200 placed on the first member 110. The first member 110 has a plurality of first claw portions 117 and second claw portions 118 that protrude toward the second member 130 at predetermined positions. The first claw portions 117 protrude upright from the longitudinal edge of the first surface portion 111. The second claw portions 118 rise toward the second member 130, then bend inward, and further rise toward the second member 130, forming a so-called crank shape. The substrate 200 has a first notch portion 221 and a second notch portion that correspond 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 fit into the first notch portion 221, and the second claw portions 118 fit into the second notch portion 222. This determines the position of the substrate 200 relative to the first member 110.

[0033] Next, the second member 130 is brought closer to the substrate 200 and the first member 110 so as to cover them. In the longitudinal direction, the second member 130 is guided relative to the substrate 200 by the first tapered portion 141 and the second tapered portion 142, and the second protrusion 136 and the third protrusion 137 abut against the edge of the substrate 200 in the longitudinal direction. This determines the positions of the first member 110, the substrate 200, and the second member 130 in the longitudinal direction. The tips of the first contact portion 132, the third contact portion 138, and the fourth contact portion 139 are guided by the bent portion of the second claw portion 118 and overlap the first upright portion 112, the third upright portion 115, and the fourth upright portion 116 in the longitudinal direction, respectively.

[0034] On the other hand, the first overlapping portion 133 is guided by the inclined portion 119 at the end of the first protruding portion 114, thereby increasing the distance between it and the first contact portion 132, the third contact portion 138, and the fourth contact portion 139. The friction generated at this time between the first contact portion 132, the third contact portion 138, and the fourth contact portion 139 and the first upright portion 112, the third upright portion 115, and the fourth upright portion 116 causes the highly insulating coating present on the surface of the first member 110 and the second member 130 to peel off, and electrical contact is ensured between the first contact portion 132, the third contact portion 138, and the fourth contact portion 139 and the first upright portion 112, the third upright portion 115, and the fourth upright portion 116.

[0035] With the substrate 200 sandwiched between the first member 110 and the second member 130 in the thickness direction, the first member 110 and the second member 130 are fastened together in the thickness direction of the substrate 200 using the fastening member 300. This completes the housing 100, and an electronic device with the substrate 200 housed inside the housing 100 is manufactured.

[0036] In the fastening portion 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 such that the distance between the two fastening members 300 aligned in the longitudinal direction is an integer fraction of a wavelength, the electrical connection between the first contact portion 132 and the first upright portion 112 prevents the portion of the second member 130 between one fastening member 300 from functioning as an antenna, thereby suppressing the emission of noise outside the housing 100.

[0037] Furthermore, since the first protrusion 114 and the first overlapping portion 133 are electrically connected, when static electricity is applied to the second member 130 from outside the housing 100, a route is formed for the static electricity to go not only to the nearby fastening member 300 but also to the connection portion between the first protrusion 114 and the first overlapping portion 133, making it possible to efficiently discharge the static electricity to the outside of the housing 100.

[0038] Furthermore, pressure is generated at three points: the contact portion between the first protruding portion 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, thereby creating a tightly fitted state between the first member 110 and the second member 130 without relative wobbling before fastening with the fastening member 300.

[0039] This disclosure is not limited to the embodiments described above. For example, other embodiments realized by arbitrarily combining the components described herein, or by excluding some of the components, may also be considered embodiments of this disclosure. Furthermore, modifications obtained by applying various modifications to the above embodiments that a person skilled in the art could conceive of, without departing from the spirit of this disclosure, i.e., the meaning of the language used in the claims, are also included in this disclosure.

[0040] For example, although the case where the first protrusion 114 is provided on the first member 110 side has been described, the first protrusion 114 may also be provided on the inner surface of the first overlapping portion 133 of the second member 130. Furthermore, the first protrusion 114 may be provided on both the first member 110 and the second member 130.

[0041] Furthermore, although the case where a connector passes through the housing 100 has been described, the circuit board 200 does not need to have a connector.

[0042] It may also be an electronic device comprising a housing 100 and a circuit board 200. Examples of electronic devices include an ECU (Electronic Control Unit) that electronically controls all or some of the functions of the mobile body 220, an audio amplifier, an active noise controller, and an active sound controller.

[0043] Furthermore, as shown in Figure 6, it may be implemented as a mobile body 220 comprising a housing 100. Examples of mobile bodies 220 include automobiles, aircraft, and ships.

[0044] (summary) The housing 100 of the first embodiment is a metal housing 100 for housing a substrate 200, and the housing 100 is composed of 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 portion 111 that covers the first main surface 201 of the substrate 200, a first upright portion 112 that rises from one end edge of the first surface portion 111 in the short direction of the first surface portion 111, and a second upright portion 113 that rises from the other end edge of the first surface portion 111 in the short direction, the second member 130 includes a second main surface 202 that is arranged on the opposite side of the first main surface 201 The first upright portion 112 comprises a rectangular second surface portion 131 that covers, a first contact portion 132 that rises from one end edge of the second surface portion 131 in the short direction and overlaps with the outer surface of the first upright portion 112 in contact with it, and a first overlapping portion 133 that rises from the other end edge of the second surface portion 131 in the short direction and overlaps with the outer surface of the second upright portion 113 with a gap between them, and at least one of the second upright portion 113 and the first overlapping portion 133 is provided with a first protruding portion 114 that maintains a predetermined distance between the second upright portion 113 and the first overlapping portion 133 and generates pressure between the first upright portion 112 and the first contact portion 132.

[0045] According to the first embodiment, the phenomenon in which noise of a predetermined frequency emitted from the housed substrate 200 is emitted to the outside by the housing 100 which functions as an antenna can be suppressed by electrically connecting the first upright portion 112 and the first contact portion 132 to change the antenna length.

[0046] Furthermore, since the first member 110 and the second member 130 are electrically connected via the first protrusion 114 located on the opposite side of the first upright portion 112, the number of routes for dissipating externally applied static electricity is increased, making it possible to efficiently discharge static electricity.

[0047] The housing 100 of the second embodiment includes the first embodiment, and the second member 130 comprises a second overlapping portion 134 and a third overlapping portion 135 that rise from both ends of the second surface portion 131 in the longitudinal direction of the second surface portion 131 and overlap with the edge of the substrate 200 with a gap between them, the second overlapping portion 134 comprises a second projection 136 that protrudes toward the substrate 200 and abuts against the edge of the substrate 200, and the third overlapping portion 135 comprises a third projection 137 that protrudes toward the substrate 200 and abuts against the edge of the substrate 200.

[0048] According to the second embodiment, the positional relationship between the first member 110 and the second member 130 in the longitudinal direction can be determined via the substrate 200. Therefore, contact between the first member 110 and the second member 130 in the longitudinal direction can be avoided, and the effects of the electrical connection between the first upright portion 112 and the first contact portion 132, and the effects of the first protruding portion 114 can be maintained without reduction.

[0049] The third embodiment of the housing 100 includes the first embodiment or the second embodiment, wherein the first upright portion 112 and the first contact portion 132 are positioned offset from the center in the longitudinal direction of the second surface portion 131.

[0050] According to the third embodiment, by positioning the connection between the first upright portion 112 and the first contact portion 132 in the center, it is possible to avoid the noise radiated from the substrate 200 having a length of one-quarter wavelength, thereby suppressing the amount of noise leaking to the outside.

[0051] The fourth embodiment of the housing 100 includes any of the first to third embodiments, and the first member 110 includes a third upright portion 115 that rises in the longitudinal direction of the first surface portion 111 at a position adjacent to the first upright portion 112, and a fourth upright portion 116 that rises in the longitudinal direction at a position opposite to the third upright portion 115 relative to the first upright portion 112, and the second member 130 includes a third contact portion 138 that overlaps in contact with the outer surface of the third upright portion 115, and a fourth contact portion 139 that overlaps in contact with the outer surface of the fourth upright portion 116.

[0052] According to the fourth embodiment, a tight fit is created at least three locations: the connection point between the third upright portion 115 and the third contact portion 138, the connection point between the fourth upright portion 116 and the fourth contact portion 139, and the position of the first protruding portion 114. This makes it possible to suppress relative rattle between the first member 110 and the second member 130 until the first member 110 and the second member 130 are connected.

[0053] The fifth embodiment of the housing 100 includes the fourth embodiment, wherein a first connector 211, which is attached to the substrate 200, is positioned between the first upright portion 112 and the third upright portion 115, and a second connector 212, which is attached to the substrate 200, is positioned between the first upright portion 112 and the fourth upright portion 116.

[0054] According to the fifth embodiment, the reduction in rigidity of the housing 100 due to the large holes through which the first connector 211 and the second connector 212 are inserted can be suppressed by connection points provided at both ends of the large holes.

[0055] The sixth embodiment of the electronic device comprises a substrate 200 and a metal housing 100 that houses the substrate 200, wherein the housing 100 is composed of a first member 110 and a second member 130 arranged in the thickness direction of the substrate 200, the first member 110 comprises a rectangular first surface portion 111 that covers the first main surface 201 of the substrate 200, a first upright portion 112 that rises from one end edge of the first surface portion 111 in the short direction of the first surface portion 111, and a second upright portion 113 that rises from the other end edge of the first surface portion 111 in the short direction, the second member 130 is arranged on the opposite side of the first main surface 201 The second surface portion 131 is rectangular and covers the second main surface 202. The first contact portion 132 rises from one end edge of the second surface portion 131 in the short direction and overlaps with the outer surface of the first upright portion 112 in contact with it.
