DETAILED DESCRIPTION OF THE INVENTION

[0009] The present embodiment will be described below with reference to the drawings. Note that the embodiment is not limited to the following embodiment. Furthermore, the content described in one embodiment is, in principle, also applicable to other embodiments. Furthermore, each embodiment and each modified example can be combined as appropriate.

[0010] (Configuration of in-vehicle device 1) As shown in FIG. 1 , the in-vehicle device 1 of this embodiment includes an electronic device (assembly) 10, a first connector 31, a second connector 32, a first cable 41, and a second cable 42. The electronic device 10 is used as a matching circuit for an antenna device (not shown). Details of the electronic device 10 will be described later. The first connector 31 is a connector for connecting to the antenna device. The second connector 32 is a connector for connecting to a signal processing device of the antenna device. For example, if the antenna device is an antenna device for FM / AM reception, the signal processing device is a radio tuner. The first cable 41 is used to electrically connect the electronic device 10 to the first connector 31. The second cable 42 is used to electrically connect the electronic device 10 to the second connector 32.

[0011] To explain the directions, the x-direction, y-direction, and z-direction are defined. The x-direction is the longitudinal direction of the cover 11 of the electronic device 10, i.e., the direction in which the first connector 31, the electronic device 10, and the second connector 32 are arranged when the first cable 41 and the second cable 42 are stretched out straight. The y-direction is one of the horizontal directions perpendicular to the x-direction. The z-direction is one of the vertical directions perpendicular to the x-direction and the y-direction. The z-direction corresponds to the direction in which the first member and the second member face each other in the claims (the direction parallel to the perpendicular to the reference plane). In this embodiment, the x-direction is the front-to-rear direction, the y-direction is the left-to-right direction, and the z-direction is the up-to-down direction. In FIG. 1 and other figures, the directions indicated by the arrows on the x-axis, y-axis, and z-axis are defined as the forward direction, the rightward direction, and the upward direction, respectively. The front-to-rear direction of the vehicle to which the in-vehicle device 1 of this embodiment is attached may or may not coincide with the x-direction.

[0012] (Electronic equipment 10) As shown in FIGS. 2 to 5, electronic device 10 has cover (first member) 11, board (held portion) 13, holding portion (second member) 15, and bracket 17. Cover 11 is hooked to holding portion 15 in a state in which board 13 is sandwiched in the z direction. An internal space is formed between cover 11 and holding portion 15, and board 13 is fixed in this internal space. That is, the z direction is the direction in which cover 11 and holding portion 15 face each other and sandwich board 13 between cover 11 and holding portion 15. Holding portion 15 to which cover 11 and board 13 are attached is attached to a vehicle (for example, inside a pillar) via bracket 17.

[0013] (Cover 11) As shown in Figure 6, cover 11 has a generally hollow rectangular parallelepiped shape with an open bottom. Cover 11 is made of resin. Cover 11 has an upper surface portion 11a, a right side surface portion 11b, a left side surface portion 11c, a front surface portion 11d, and a rear surface portion 11e. Upper surface portion 11a, right side surface portion 11b, left side surface portion 11c, front surface portion 11d, and rear surface portion 11e are integrally formed.

[0014] (Top part 11a) The top surface portion 11a has a surface that is approximately perpendicular to the z direction and constitutes the top surface of the cover 11. A right side surface portion 11b extends downward in the z direction from the right end of the top surface portion 11a. A left side surface portion 11c extends downward in the z direction from the left end of the top surface portion 11a. A front surface portion 11d extends downward in the z direction from the front end of the top surface portion 11a. A rear surface portion 11e extends downward in the z direction from the rear end of the top surface portion 11a. A rib 11a1 that protrudes downward in the z direction is provided on the underside of the top surface portion 11a. The rib 11a1 differs from the latch portion of the first member in the claims. The rib 11a1 presses the board main body 13a from above in the z direction. The rib 11a1 may also be provided on the inner walls of the side surfaces (right side surface portion 11b, front surface portion 11d, etc.). For example, the rib 11a1 of this embodiment is configured to contact the inner wall of any of the right side surface portion 11b, left side surface portion 11c, front surface portion 11d, and rear surface portion 11e, and the lower surface of the upper surface portion 11a.

[0015] (Right side part 11b) The right side surface 11b has a surface that is approximately perpendicular to the y direction and constitutes the right side of the cover 11. A right claw 11b1 that protrudes leftward in the y direction is provided on the lower part of the inner surface of the right side surface 11b. The right claw 11b1 comes into contact with an area that contacts the upper edge of a right latch hole 15b1 in the right wall 15b, which will be described later. The right claw 11b1 constitutes the right latch portion of the cover 11.

[0016] As shown in Figure 7, the area of ​​the right claw portion 11b1 that contacts the right wall 15b has a first right contact area 11b11 and a second right contact area 11b12. The first right contact area 11b11 forms an inclined surface that extends diagonally downward and left from the inner surface of the right side surface portion 11b. The second right contact area 11b12 is adjacent to the first right contact area 11b11 and is located closer to the tip of the right claw portion 11b1 than the first right contact area 11b11. The second right contact area 11b12 forms a flat surface that extends leftward in the y direction from the bottom end of the first right contact area 11b11, or an inclined surface that extends diagonally downward and left from the bottom end of the first right contact area 11b11.

[0017] That is, the first right contact area 11b11 is inclined with respect to the xy plane (reference plane). The second right contact area 11b12 is parallel to the xy plane or inclined with respect to the xy plane at an angle different from that of the first right contact area 11b11. Specifically, as shown in FIG. 8, the inclination angle (first inclination angle θ1) of the inclined surface forming the first right contact area 11b11 with respect to the xy plane is greater than the inclination angle (second inclination angle θ2) of the plane or inclined surface forming the second right contact area 11b12 with respect to the xy plane (90°>θ1>θ2≧0°). A valley (first valley A1) is formed at the boundary between the first right contact area 11b11 and the second right contact area 11b12, facing the right wall 15b.

[0018] By providing the first right contact region 11b11 with an inclination (90° > θ1 > 0°), variations in the thickness of the clamped portion (substrate 13) can be absorbed, enabling assembly without rattle. By providing the second right contact region 11b12 with a gentler inclination than the first right contact region 11b11 (θ1 > θ2 ≧ 0°), even if the right claw portion 11b1 that was in contact with the right latch hole 15b1 at the first right contact region 11b11 shifts and the contact position changes, the first valley portion A1 or the second right contact region 11b12 will catch on the right latch hole 15b1. In other words, the right claw portion 11b1 is less likely to come off the right wall 15b, and the cover 11 is less likely to come off the holding portion 15.

[0019] The width of the first right contact area 11b11, i.e., the width of the inclined surface that forms the first right contact area 11b11 (dimension in the y direction, first width d1), is longer than the width of the second right contact area 11b12, i.e., the width of the flat or inclined surface that forms the second right contact area 11b12 (dimension in the y direction, second width d2) (d1>d2). By widening the first width d1, 11 This widens the area of ​​contact with the right hook hole 15b1 in b11, making it easier to accommodate variations in the thickness of the clamped portion (substrate 13). To prevent the right claw portion 11b1 from coming off the right wall 15b due to the catch, the second width d2 (the amount of protrusion in the y direction of the second right contact area 11b12) is adjusted based on the holding force between the cover 11 and the holding portion 15, etc.

[0020] The height (dimension in the z direction, slope height h1) of the inclined surface forming the first right contact area 11b11 is determined so as to satisfy the following condition: When at least one of the substrate 13 and the holder 15 is thick due to tolerance, thermal expansion, thermal contraction, etc. (see FIG. 9), the lower end of the first right contact area 11b11 comes into contact with the right wall 15b, and when at least one of the substrate 13 and the holder 15 is thin (see FIG. 10), the upper end of the first right contact area 11b11 comes into contact with the right wall 15b.

[0021] (Left side part 11c) The left side surface 11c has a surface that is approximately perpendicular to the y direction and constitutes the left side of the cover 11. A left claw 11c1 that protrudes rightward in the y direction is provided on the lower part of the inner surface of the left side surface 11c. The left claw 11c1 comes into contact with an area that contacts the upper edge of a left latch hole 15c1 in the left wall 15c, which will be described later. The left claw 11c1 constitutes the left latch portion of the cover 11.

[0022] The area of ​​the left claw portion 11c1 that contacts the left wall 15c has a first left contact area 11c11 and a second left contact area 11c12 (see FIG. 7). The first left contact area 11c11 forms an inclined surface that extends diagonally downward to the right from the inner surface of the left side surface portion 11c. The second left contact area 11c12 is adjacent to the first left contact area 11c11 and is located closer to the tip of the left claw portion 11c1 than the first left contact area 11c11. The second left contact area 11c12 forms a flat surface that extends rightward in the y direction from the bottom end of the first left contact area 11c11, or an inclined surface that extends diagonally downward to the right from the bottom end of the first left contact area 11c11.

[0023] That is, the first left contact area 11c11 is inclined with respect to the xy plane (reference plane). The second left contact area 11c12 is parallel to the xy plane or is inclined with respect to the xy plane at an angle different from that of the first left contact area 11c11. The inclination angle of the inclined surface forming the first left contact area 11c11 with respect to the xy plane is greater than the inclination angle of the plane or inclined surface forming the second left contact area 11c12 with respect to the xy plane. A valley (second valley A2) is formed at the boundary between the first left contact area 11c11 and the second left contact area 11c12, on the side facing the left wall 15c.

[0024] By providing the inclined first left contact region 11c11, variations in the thickness of the clamped portion (substrate 13) can be absorbed, enabling assembly without rattle. By providing the second left contact region 11c12 with a gentler inclination than the first left contact region 11c11, even if the left claw portion 11c1 that was in contact with the left latch hole 15c1 at the first left contact region 11c11 shifts and the contact position changes, the second valley portion A2 or the second left contact region 11c12 will catch on the left latch hole 15c1. In other words, the left claw portion 11c1 is less likely to come off the left wall 15c, and the cover 11 is less likely to come off the holding portion 15.

[0025] The width of the first left contact area 11c11, i.e., the width (dimension in the y direction) of the inclined surface that forms the first left contact area 11c11, is longer than the width of the second left contact area 11c12, i.e., the width (dimension in the y direction) of the flat or inclined surface that forms the second left contact area 11c12. . By widening the width of the first left contact area 11c11, 11 The area of ​​contact with the left latch hole 15c1 in c11 can be widened, making it easier to accommodate variations in the thickness of the clamped portion (substrate 13). To prevent the left claw portion 11c1 from coming off the left wall 15c due to the catch, the width of the second left contact area 11c12 (the amount of protrusion in the y direction of the second right contact area 11b12) is adjusted based on the holding force between the cover 11 and the holding portion 15, etc.

[0026] The height (dimension in the z direction) of the inclined surface forming the first left contact area 11c11 is determined so as to satisfy the following condition: When at least one of the substrate 13 and the holder 15 is thick due to tolerance, thermal expansion, thermal contraction, etc., the lower end of the first left contact area 11c11 comes into contact with the left wall 15c, and when at least one of the substrate 13 and the holder 15 is thin, the upper end of the first left contact area 11c11 comes into contact with the left wall 15c.

[0027] (Symmetry between right claw 11b1 and left claw 11c1) The area of ​​the right claw 11b1 that contacts the right wall 15b and the area of ​​the left claw 11c1 that contacts the left wall 15c are configured to be symmetrical when viewed from the x direction. That is, the first right contact area 11b11 and the first left contact area 11c11 have the same dimensions and are arranged to be symmetrical, and the second right contact area 11b12 and the second left contact area 11c12 have the same dimensions and are arranged to be symmetrical.

[0028] (Front part 11d) The front surface 11d has a surface that is approximately perpendicular to the x-direction and constitutes the front surface of the cover 11 (see FIGS. 5 and 6). A notch (front notch 11d1) is provided at the lower end of the center of the front surface 11d in the y-direction, extending upward in the z-direction from the lower end. The front notch 11d1 is approximately U-shaped when viewed from the x-direction. When the cover 11 is attached to the holding part 15 with the board 13 attached, the first cable 41 passes through the front notch 11d1. A front claw 11d2 that protrudes rearward in the x-direction is provided at the lower end of the inner surface of the front surface 11d. When the cover 11 is attached to the holding part 15 with the board 13 attached, the front claw 11d2 engages with a front latch protrusion 15d1, which will be described later.

[0029] (Rear section 11e) The rear surface portion 11e has a surface that is approximately perpendicular to the x-direction and constitutes the rear surface of the cover 11. A notch (rear notch 11e1) is provided at the lower end of the rear surface portion 11e in the center in the y-direction, extending from the lower end upward in the z-direction. The rear notch 11e1 has a substantially U-shape when viewed from the x-direction. When the cover 11 is attached to the holding part 15 with the board 13 attached, the second cable 42 passes through the rear notch 11e1. A rear claw portion 11e2 that protrudes forward in the x-direction is provided at the lower end of the inner surface of the rear surface portion 11e. When the cover 11 is attached to the holding part 15 with the board 13 attached, the rear claw portion 11e2 engages with a rear latch protrusion 15e1, which will be described later.

[0030] (Substrate 13) The board body 13a of the board 13 includes a matching circuit or other circuit that performs impedance matching for the reception signal or transmission signal of the antenna device connected via the first connector 31 (see FIG. 4). The board 13 is connected to a first cable 41 at its front in the x direction and to a second cable 42 at its rear in the x direction. The board body 13a is formed with solder connection holes 13b and claw notches 13c. When the board 13 is attached to the holder 15, right solder connection protrusions 15b2 and left solder connection protrusions 15c2 of the holder 15 are fitted into the solder connection holes 13b and soldered. The claw notches 13c are provided at the ends of the board body 13a in the y direction.

[0031] When the cover 11 is attached to the holder 15 with the board 13 attached, the right claw 11b1 of the cover 11 passes through the claw notch 13c on the right side in the y direction, and the left claw 11c1 of the cover 11 passes through the claw notch 13c on the left side in the y direction. By providing the claw notches 13c, it is possible to prevent the right claw 11b1 and the left claw 11c1 from hitting the board main body 13a and damaging the board main body 13a.

[0032] (Holding part 15) The holding portion 15 holds the substrate 13. The substrate 13 and the holding portion 15 are attached by fitting, soldering, or the like. The cover 11 is detachably fastened to the holding portion 15. Specifically, the cover 11 is attached to the holding portion 15 by fastening the right claw portion 11b1 to the right fastening hole 15b1, the left claw portion 11c1 to the left fastening hole 15c1, the front claw portion 11d2 to the front fastening protrusion 15d1, and the rear claw portion 11e2 to the rear fastening protrusion 15e1.

[0033] The holder 15 has a generally hollow rectangular parallelepiped shape with an open top. The holder 15 has a holder main body 15a, a right wall 15b, a left wall 15c, a front wall 15d, and a rear wall 15e. The holder main body 15a, the right wall 15b, the left wall 15c, the front wall 15d, and the rear wall 15e are integrally formed. The holder 15 is made of metal and is electrically connected to the substrate 13 and the bracket 17.

[0034] (Holding unit body 15a) The holder body 15a has a surface that is approximately perpendicular to the z direction and constitutes the lower surface of the holder 15. The holder body 15a is fixed to the bracket 17 by screwing, fitting, welding, or the like. A right wall 15b extends upward in the z direction from the right end of the holder body 15a. A left wall 15c extends upward in the z direction from the left end of the holder body 15a. A front wall 15d extends upward in the z direction from the front end of the holder body 15a. A rear wall 15e extends upward in the z direction from the rear end of the holder body 15a.

[0035] (Right wall 15b) The right wall 15b has a surface that is approximately perpendicular to the y-direction and constitutes the right surface of the holding portion 15. A hole (right latching hole 15b1) for latching the right claw portion 11b1 is formed in the right wall 15b. The right wall 15b and the right latching hole 15b1 constitute the right latched portion of the holding portion 15. In addition, a protrusion (right solder connection protrusion 15b2) that protrudes upward in the z-direction is provided on the upper part of the right wall 15b.

[0036] (Left wall 15c) The left wall 15c has a surface that is approximately perpendicular to the y direction and constitutes the left surface of the holding portion 15. A hole (left latching hole 15c1) for latching the left claw portion 11c1 is formed in the left wall 15c. The left wall 15c and the left latching hole 15c1 constitute the left latched portion of the holding portion 15. In addition, a protrusion (left solder connection protrusion 15c2) that protrudes upward in the z direction is provided on the upper portion of the left wall 15c.

[0037] (front wall 15d) The front wall 15d has a surface that is approximately perpendicular to the x direction, and constitutes the front surface of the holding portion 15. A front latch protrusion 15d1 that protrudes forward in the x direction is provided on the upper portion of the front wall 15d.

[0038] (back wall 15e) The rear wall 15e has a surface that is approximately perpendicular to the x direction, and constitutes the rear surface of the holding portion 15. A rear latch protrusion 15e1 that protrudes rearward in the x direction is provided on the upper portion of the rear wall 15e.

[0039] (Bracket 17) Bracket 17 is made of metal. Bracket 17 is attached to a metal part of the vehicle. Grounding is achieved by attaching substrate 13 to holding portion 15, holding portion 15 to bracket 17, and bracket 17 to a metal part of the vehicle. Holding portion 15 and bracket 17 are attached by screwing, fitting, welding, or the like. Alternatively, holding portion 15 and bracket 17 may be integrally configured.

[0040] (Assembly procedure) Next, a description will be given of the procedure for assembling the electronic device 10. A first cable 41 is attached by soldering to the front side of the board body 13a in the x direction. A second cable 42 is also attached by soldering to the rear side of the board body 13a in the x direction.

[0041] The holding portion 15 is attached to the bracket 17 (holding portion attaching step). The board 13 is attached to the holding portion 15 (board attaching step). Specifically, the right solder connection protrusion 15b2 and the left solder connection protrusion 15c2 of the holding portion 15 are fitted into the solder connection holes 13b of the board main body 13a, and then fixed by soldering.

[0042] The cover 11 is attached to the holder 15 (cover attachment step). Specifically, the right claw 11b1 is hooked into the right latch hole 15b1, and the left claw 11c1 is hooked into the left latch hole 15c1. (figure 9 , see Figure 10 The front claw portion 11d2 is hooked to the front latch protrusion 15d1, and the rear claw portion 11e2 is hooked to the rear latch protrusion 15e1.

[0043] At this time, the rib 11a1 of the cover 11 contacts the upper surface of the board body 13a and applies a downward force in the z direction to the board body 13a. The right claw 11b1 also contacts the right wall 15b and applies an upward force in the z direction to the board body 13a via the right wall 15b. Specifically, the area of ​​the right wall 15b that contacts the upper edge of the right latch hole 15b1 contacts the first right contact area 11b11 of the right claw 11b1. The left claw 11c1 also contacts the left wall 15c and applies an upward force in the z direction to the board body 13a via the left wall 15c. Specifically, the area of ​​the left wall 15c that contacts the upper edge of the left latch hole 15c1 contacts the first left contact area 11c11 of the left claw 11c1.

[0044] As a result, the cover 11 is fixed to the holding portion 15 with the substrate 13 sandwiched in the z direction. In addition, the inclined surfaces of the first right contact area 11b11 and the first left contact area 11c11 maintain the state in which the cover 11 is latched to the holding portion 15 while the contact position between the cover 11 and the holding portion 15 can vary.

[0045] 9, when at least one of a substrate 13 in which the thickness in the z direction of the substrate body 13a is thicker than the average substrate body 13a due to tolerance and a retaining portion 15 in which the thickness in the z direction is thicker than the average retaining portion 15 is used, a portion of the first right contact region 11b11 below in the z direction contacts the right wall 15b, and a portion of the first left contact region 11c11 below in the z direction contacts the left wall 15c. When at least one of a case in which the thickness of the substrate body 13a in the z direction increases due to thermal expansion and a case in which the thickness of the retaining portion 15 in the z direction increases due to thermal expansion, a portion of the first right contact region 11b11 below in the z direction contacts the right wall 15b, and a portion of the first left contact region 11c11 below in the z direction contacts the left wall 15c.

[0046] 10 , when at least one of a substrate 13 in which the thickness of the substrate body 13a in the z direction is thinner than the average substrate body 13a due to tolerance and a retaining portion 15 in which the thickness in the z direction is thinner than the average retaining portion 15 is used, the upper portion of the first right contact region 11b11 in the z direction contacts the right wall 15b, and the upper portion of the first left contact region 11c11 in the z direction contacts the left wall 15c. Even when at least one of the cases in which the thickness of the substrate body 13a in the z direction is thinner due to thermal contraction and the thickness of the retaining portion 15 in the z direction is thinner, the upper portion of the first right contact region 11b11 in the z direction contacts the right wall 15b, and the upper portion of the first left contact region 11c11 in the z direction contacts the left wall 15c.

[0047] (Effect of the inclined surface forming the contact area) When latching, the area of ​​the latching portion (right claw portion 11b1, left claw portion 11c1) that comes into contact with the latched portion (right wall 15b, left wall 15c) can be displaced along the inclined surface. Therefore, even if variations in size occur due to tolerances, thermal expansion, thermal contraction, etc., no rattle occurs and the latching fixation can be maintained. In other words, the assembled state of an assembly such as electronic device 10 can be easily maintained.

[0048] Also, it becomes possible to attach the cover 11 to the holding portion 15 without using screws, which allows the electronic device 10 to be miniaturized and constructed inexpensively. Furthermore, since no screws made of metal are used, noise generation can be suppressed more effectively than in a configuration in which screws made of metal are used.

[0049] (Effects of Providing the Second Right Contact Area 11b12 and the Second Left Contact Area 11c12) A second right contact area 11b12 with a different inclination angle is provided at the tip of the first right contact area 11b11, and a valley (first valley A1) is formed at the boundary between the first right contact area 11b11 and the second right contact area 11b12 when viewed from the x direction. A second left contact area 11c12 with a different inclination angle is provided at the tip of the first left contact area 11c11, and a valley (second valley A2) is formed at the boundary between the first left contact area 11c11 and the second left contact area 11c12 when viewed from the x direction.

[0050] Even if the contact portion with the right wall 15b is shifted downward in the z direction from the first right contact region 11b11, the contact portion with the right wall 15b is unlikely to shift beyond the first valley portion A1 to the second right contact region 11b12, and the right claw portion 11b1 is unlikely to come off the right latch hole 15b1. Even if the contact portion with the left wall 15c is shifted downward in the z direction from the first left contact region 11c11, the contact portion with the left wall 15c is unlikely to shift beyond the second valley portion A2 to the second left contact region 11c12, and the left claw portion 11c1 is unlikely to come off the left latch hole 15c1. In other words, compared to a configuration in which the second right contact region 11b12 and the second left contact region 11c12 are not provided, it is easier to maintain the state in which the cover 11 is latched to the holder 15.

[0051] (Effect of sandwiching the substrate 13 in the z direction) By sandwiching the clamped portion (substrate 13) between cover 11 and holding portion 15, rattle does not occur, and the state in which cover 11 is latched to holding portion 15 can be easily maintained.

[0052] (Effect of forming the cover 11 from resin) Compared to a configuration in which the cover 11 is made of metal, the cover 11 can be made lighter and less expensive. Even if the cover 11 is made of resin, in this embodiment, the contact position between the latching portion and the latched portion can be adjusted by using the inclined surfaces of the contact areas of the claw portions (such as the first right contact area 11b11). This prevents rattling and makes it easy to maintain the attached state (latched state) of the assembly (electronic device 10).

[0053] (Application example of Cover 11) In this embodiment, an example has been described in which the cover 11 is made of resin, but the cover 11 may also be made of metal.

[0054] (Example of application to assemblies other than the electronic device 10) In the present embodiment, an example has been described in which cover 11, which corresponds to a first member, is hooked to holding portion 15, which corresponds to a second member, to form electronic device 10, which corresponds to an assembly. However, the assembly is not limited to electronic device 10 including substrate 13, and may be another assembly (for example, a container) including a first member including a hooking portion and a second member including a hooked portion.

[0055] (Application example 1 of the clamped portion (substrate 13)) In the present embodiment, an example has been described in which the substrate 13 corresponding to the clamped portion includes a matching circuit. However, the substrate 13 may include other circuits, such as an amplifier circuit, without including a matching circuit.

[0056] (Application example 2 of the clamped portion (substrate 13)) In addition, in this embodiment, an example has been described in which the substrate 13 corresponding to the clamped portion is configured as a separate body from the cover 11 corresponding to the first member and the holding portion corresponding to the second member. However, the clamped portion may be configured as one body with the first member or one body with the second member.

[0057] (Application example 1 of the hooking part and the hooked part) In this embodiment, an example has been described in which the latching portion of the cover (first member) 11 includes claw portions (right claw portion 11b1, left claw portion 11c1), and the latched portion of the holding portion (second member) 15 includes latching holes (right latching hole 15b1, left latching hole 15c1). However, the latching portion and the latched portion are not limited to a combination of a claw and a hole. For example, the latching portion and the latched portion may be configured by a claw and another claw that engages with the claw.

[0058] (Application example 2 of the hooking part and the hooked part) In addition, in the present embodiment, an example has been described in which cover 11 corresponds to the first member and includes a latching portion, and holding portion 15 corresponds to the second member and includes a latched portion. However, cover 11 may correspond to the second member and include a latched portion, and holding portion 15 may correspond to the first member and include a latching portion. In this case, holes or notches corresponding to the latching holes are provided in cover 11, and protrusions corresponding to the claws are provided in holding portion 15. Furthermore, both cover 11 and holding portion 15 may correspond to the first member and include a latching portion, and both cover 11 and holding portion 15 may correspond to the second member and include a latched portion.

[0059] (Application example 3 of the hooking part and hooked part) In the present embodiment, the right wall 15b and the left wall 15c are formed with holes for latching (right latching hole 15b1, left latching hole 15c1), and the upper edges of the holes and the boundaries between the walls are in contact with the claws (right claw 11b1, left claw 11c1). However, the latching area is not limited to a hole, and may have other shapes such as a notch or a flange.

[0060] (Application example 4 of the hooking part and hooked part) In this embodiment, an example has been described in which an inclined region (such as the first right contact region 11b11) is provided on the latching portion (right claw portion 11b1, left claw portion 11c1) provided on the tip of the cover 11. However, an inclined region may be provided on the member (rib 11a1) that clamps the clamped portion (substrate 13) with the latching portion. In this case, an inclined surface is formed in the region of the member that comes into contact with the contacted portion. In a state in which the contact position between the contacted portion and the member can be changed, the latching portion is latched on the latched portion. maintain The member is not limited to the reinforcing rib 11a1 of the cover 11, but may be formed of a protrusion or the like separate from the rib 11a1.

[0064] (Aspect 2) Preferably, the contact area includes a first contact area and a second contact area, the second contact area being adjacent to the first contact area and positioned distal to the first contact area, the second contact area being parallel to the reference plane or inclined at a different angle relative to the reference plane than the first contact area.

[0065] According to the second aspect, it is easier to maintain the state in which the first member is attached to the second member, compared to an aspect in which the second contact region is not provided.

[0066] (Aspect 3) More preferably, the width of the second contact area is smaller than the width of the first contact area.

[0067] (Aspect 4) More preferably, the angle of inclination of the first contact area relative to the reference plane is larger than the angle of inclination of the second contact area relative to the reference plane.

[0068] According to the fourth aspect, the inclination angle of the first contact area relative to the reference plane is set to be smaller than the inclination angle of the second contact area relative to the reference plane. small Compared to the above-described configuration, even if the contact position fluctuates, the first member is less likely to come off the contact area, making it easier to maintain the state in which the first member is attached to the second member.

[0069] (Aspect 5) More preferably, one of the first member and the second member is a cover, and the other of the first member and the second member is a holding part. The cover has one of a hooking part and a hooked part that is hooked onto the hooking part. The holding part has the other of the hooking part and the hooked part.

[0070] According to the fifth aspect, the contact position between the latching part and the latched part can be adjusted by using the inclined surface of the first contact area, etc. This prevents rattle and makes it easy to maintain the attached state (latched state) of the assembly (electronic device).
