Below, a detailed description of a form for carrying out the invention (hereinafter, referred to as an embodiment) will be given with reference to the drawings. Note that the present invention is not limited to the following embodiment. Furthermore, the components in the following embodiment include those that a person skilled in the art can easily imagine, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the components disclosed in the following embodiment can be combined as appropriate.

Figure 1 is a perspective view of an electronic device according to an embodiment. Figure 2 is a cross-sectional view of an electronic device and a wiring structure according to an embodiment.

The electronic device 1 is, for example, an AV-integrated car navigation system or car audio. As shown in FIG. 1, the electronic device 1 has a main body unit 2 and a panel unit 3.

The main body 2 is a housing that is open at the front and has the other sides, top, bottom, right side, left side, and rear, sealed with sheet metal. Therefore, the main body 2 has an upper plate 2A, a lower plate 2B, a right plate 2C, a left plate 2D, and a rear plate 2E, which are all sheet metal. Here, the front, top, bottom, right side, left side, and rear side of the electronic device 1 are defined as the respective directions when the electronic device 1 is mounted in front of the driver's seat of the vehicle. The surface facing the driver's seat is the "front side," the surface facing the windshield at the front of the vehicle is the "rear side," and the right side and left side are the directions as viewed from the front.

The panel unit 3 is installed on the front side of the main body unit 2. As shown in Figures 1 and 2, the panel unit 3 is fixed to the front side of the main body unit 2 and configured as an integral unit. The panel unit 3 has a panel frame 3A, a display 3B, a support plate 3C, and a fixing plate 3D.

The panel frame 3A covers the front side of the main body 2 and is made of synthetic resin. In this embodiment, the panel frame 3A is larger than the main body 2 in the left-right and up-down directions. The panel frame 3A is a frame body whose rear side is open (see Figures 2 and 3) and whose other sides, top, bottom, right and left, are closed. Therefore, the panel frame 3A has an upper plate 3Aa, a lower plate 3Ab, a right plate 3Ac and a left plate 3Ad. The panel frame 3A also has a front plate 3Ae on the front side that is connected to the upper plate 3Aa, the lower plate 3Ab, the right plate 3Ac and the left plate 3Ad. The front plate 3Ae has a window portion 3Aea that exposes the display 3B, as shown in Figure 1.

As shown in FIG. 1, the display 3B is small in the left-right and up-down directions of the panel frame 3A, and is stored inside the panel frame 3A in the left-right and up-down directions. The display 3B is, for example, configured as a liquid crystal display (LCD) or an organic electro-luminescence (EL) display. Although not shown in the figure, the outside of the display 3B in the left-right and up-down directions and the inside of the panel frame 3A in the left-right and up-down directions may have operation buttons for performing various operations on the electronic device 1.

The support plate 3C is made of sheet metal and is provided with a plate surface that extends up, down, left and right so as to cover the opening on the rear side of the panel frame 3A. The support plate 3C is fixed to the front plate 3Ae of the panel frame 3A via multiple support parts 10A that protrude rearward from the front plate 3Ae of the panel frame 3A. The support plate 3C covers the rear side of the panel frame 3A and functions as a decorative plate that covers the second substrate 5, which will be described later. This support plate 3C is attached to the main body part 2 side so as to cover the opening on the front side of the main body part 2.

The fixing plate 3D is made of sheet metal and is installed inside the panel frame 3A with its plate surface extended in the up, down, left and right directions so as to be parallel to the support plate 3C. The fixing plate 3D is disposed between the front plate 3Ae of the panel frame 3A and the support plate 3C, and is fixed to the support plate 3C via multiple columnar support parts 10B extending in the front-rear direction.

2, the electronic device 1 has a first board 4 and a second board 5. The first board 4 is provided inside the main body 2 along the lower plate 2B with the plate surface extended in the front-rear and left-right directions. That is, the first board 4 has an upper surface 4A facing upward and a lower surface 4B facing downward. The first board 4 is fixed to the lower plate 2B via a plurality of support parts 10C protruding upward from the lower plate 2B. Since the first board 4 is provided inside the main body 2, it is also called the main body side board. The first board 4 has a first connector 6 fixed to the front part of the upper surface 4A. The first connector 6 has an insertion port 6A formed facing forward. Since the first connector 6 is provided on the main body side board, it is also called the main body side connector.

The second board 5 is provided inside the panel frame 3A in the panel section 3. The second board 5 is provided with its plate surface expanded in the up, down, left and right directions. That is, the second board 5 is arranged in a substantially perpendicular direction, which is a different direction from the first board 4, and has a front surface 5A facing forward and a rear surface 5B facing backward. The second board 5 is arranged between the support plate 3C and the fixed plate 3D inside the panel frame 3A, parallel to the support plate 3C and the fixed plate 3D, and is fixed to the fixed plate 3D via a plurality of columnar support parts 10D extending in the front-rear direction. Since the second board 5 is provided inside the panel frame 3A, it is also called the panel side board. The second board 5 has a second connector 7 fixed to the lower part of the rear surface 5B. The second connector 7 has a plug portion 7A formed toward the rear. The second connector 7 is electrically connected to each other by inserting the plug portion 7A into the plug 6A of the first connector 6. The second connector 7 is also called the panel-side connector because it is provided on the panel-side board.

The second board 5 has, for example, a display 3B mounted thereon. On the other hand, the first board 4 has, for example, a control circuit mounted thereon, though this is not shown in the figure. The control circuit supplies power to the display 3B provided on the second board 5, inputs signals from the operation buttons of the panel frame 3A and the display 3B, and outputs signals to the display 3B. Therefore, by connecting the first connector 6 and the second connector 7, the control circuit of the first board 4 and the display 3B of the second board 5 are electrically connected.

In this configuration, starting from the second connector 7, which is the panel side connector, the second connector 7 is fixed to the second board 5, which is the panel side board. The second board 5 is also fixed to the fixing plate 3D of the panel section 3. The fixing plate 3D is also attached to the main body section 2 via the support plate 3C. The main body section 2 is also fixed to the first board 4, which is the main body side board. The first connector 6, which is the main body side connector, is also fixed to the first board 4. The first connector 6 and the second connector 7 are then electrically connected to each other.

If the electrical connection between the first connector 6 and the second connector 7 is not stable, there is a risk that the input and output of signals between the control circuit of the first board 4 and the display 3B of the second board 5 will become unstable. Therefore, the positional accuracy of the first connector 6 and the second connector 7 is important. However, there is a problem in that it is difficult to maintain the positional accuracy of the first connector 6 and the second connector 7 due to the combined error of the attachment intersections of the positioning of the second connector 7 and the second board 5, the positioning of the second board 5 and the fixing plate 3D, the positioning of the fixing plate 3D and the support plate 3C, the positioning of the support plate 3C and the main body 2, the positioning of the main body 2 and the first board 4, and the positioning of the first board 4 and the first connector 6.

Figure 3 is a cross-sectional view of an electronic device, wiring structure, and fastener according to an embodiment. Figure 4 is a perspective view of the fastener according to an embodiment. Figures 5 and 6 are perspective views of the fastener according to an embodiment in use.

To address the above problem, the embodiment uses a fixing bracket 8, which is a fixing member shown in Figures 3 to 6. The fixing bracket 8 is made of a metal plate, and maintains the positional accuracy of the first connector 6 and the second connector 7 by positioning the first board 4 and the second board 5, which are arranged in different directions, relative to each other. Note that the fixing bracket 8, which is a fixing member, is not limited to being made of metal, and may be made of a hard synthetic resin.

As shown in FIG. 4, the fixing bracket 8 has a base 8A, a first claw portion 8B, a second claw portion 8C, a contact portion 8D, and screw holes (fixing portions) 8E and 8F.

The base 8A is formed in a plate shape and is disposed along the lower surface 4B of the first substrate 4. The base 8A is formed to extend in the left-right direction. The base 8A has a drawn portion 8Aa to suppress deformation of the base 8A. The drawn portion 8Aa is formed by applying pressure to a portion of the plate shape of the base 8A to draw it out and form projections and recesses. In the embodiment, the drawn portion 8Aa is formed by forming projections and recesses that extend along the left-right direction in which the base 8A extends. As shown in FIG. 5, the base 8A is formed to extend longer in the left-right direction than the first connector 6.

The first claw portion 8B is formed on the base 8A. Specifically, the first claw portion 8B is formed by cutting upward a part of each tongue piece 8Ab extending rearward integrally with the base 8A at both left and right ends of the base 8A. Therefore, the first claw portion 8B is provided at both left and right ends of the base 8A and formed to protrude upward. As shown in Figures 5 and 6, the first claw portion 8B engages with a first recess 4C formed at the front end of the first board 4. The first recess 4C is formed as a notch that opens forward at the front end of the first board 4. The first recess 4C is formed on both the left and right sides of the first connector 6. Although not shown in the figure, the first recess 4C may be configured as a groove formed within the thickness of the first board 4 or a hole formed through the first board 4 instead of the notch, and the first claw portion 8B may engage with this groove or hole. Thus, in this embodiment, a pair of first claws 8B engage with the first recesses 4C formed in the first substrate 4 at positions on both the left and right sides of the first connector 6 (see FIG. 6).

Each tongue piece 8Ab is provided along the lower surface 4B of the first substrate 4. Each tongue piece 8Ab abuts against the lower surface 4B of the first substrate 4 when the first connector 6 of the first substrate 4 and the second connector 7 of the second substrate 5 are connected to each other. Each tongue piece 8Ab has a screw hole 8E formed behind the first claw portion 8B. The screw hole 8E is fitted with a screw 8G shown in FIG. 3. This screw hole 8E coincides with the screw hole 4D formed in the first substrate 4 when the first connector 6 of the first substrate 4 and the second connector 7 of the second substrate 5 are connected to each other as shown in FIG. 5. The screw hole 4D is fitted with a screw 8G shown in FIG. 3. Therefore, the base 8A is fixed to the first substrate 4 by the screw 8G via each tongue piece 8A. In this way, the screw hole 8E constitutes a fixing portion for fixing the first substrate 4.

The second claw portion 8C is formed on the base 8A. Specifically, the second claw portion 8C is formed to extend forward integrally with the base 8A at the end side rather than the center, halfway along the left-right direction of the base 8A. Therefore, the second claw portion 8C is provided at two positions in the left-right direction of the base 8A, and is formed to protrude forward. As shown in FIG. 5 and FIG. 6, the second claw portion 8C engages with the second recess 5C formed in the second substrate 5. The second recess 5C is formed as a hole penetrating the second substrate 5. The second recess 5C is formed on both the left and right sides below the second connector 7. Although not shown in the figure, the second recess 5C may be configured as a groove formed within the thickness of the second substrate 5 instead of the above-mentioned hole form, and the second claw portion 8C may engage with this groove. Thus, in the embodiment, a pair of second claw portions 8C engage with the second recesses 5C formed in the second substrate 5 on both the left and right sides below the second connector 7 (see FIG. 5 and FIG. 6).

The abutment portion 8D is formed on the base portion 8A. Specifically, the abutment portion 8D is formed integrally with the base portion 8A at the center of the base portion 8A in the left-right direction, bending from the front end and extending downward. Therefore, the abutment portion 8D is formed at the front end at the center of the base portion 8A in the left-right direction, protruding downward. As shown in FIG. 5, the abutment portion 8D abuts against the rear surface 5B of the second substrate 5 when the first connector 6 of the first substrate 4 and the second connector 7 of the second substrate 5 are connected to each other.

The abutment portion 8D has a screw hole 8F formed therein. The screw hole 8F is fitted with a screw 8H shown in FIG. 3. This screw hole 8F coincides with the screw hole 5D (see FIG. 2) formed in the second substrate 5 when the second claw portion 8C is engaged with the second recess 5C formed in the second substrate 5. The screw 8H shown in FIG. 3 and FIG. 5 is fitted into the screw hole 5D. Therefore, the base 8A is fixed to the second substrate 5 by the screw 8H via the abutment portion 8D. In this way, the screw hole 8F constitutes a fixing portion for fixing the second substrate 5. This abutment portion 8D is formed by bending the base 8A at the center of the base 8A extending in the left-right direction, thereby ensuring the rigidity of the base 8A.

The fixing portion is composed of the screw holes 8E and 8F as described above. The screw hole 8E fixes the first board 4 to a part of the fixing bracket 8, and the screw hole 8F fixes the second board 5 to a part of the fixing bracket 8. In this way, the screw holes 8E and 8F, which are the fixing portions, fix the first board 4 and the second board 5 in a state in which they are arranged in different directions.

In such an embodiment, the fixing bracket 8 is configured such that the first connector 6 of the first board 4 and the second connector 7 of the second board 5 are connected to each other, and the screw holes 8E and 8F fix the first board 4 and the second board 5 in a state in which they are arranged in different directions, the first claw portion 8B engages with the first recess 4C of the first board 4, and the second claw portion 8C engages with the second recess 5C of the second board 5. As a result, the engagement of the first claw portion 8B and the second claw portion 8C restricts the movement of the first board 4 in the left-right direction, and restricts the movement of the second board 5 in the left-right direction and the up-down direction. Therefore, in the left-right direction (first direction), the first board 4 and the second board 5 are displaced in the same phase, and the first connector 6 of the first board 4 and the second connector 7 of the second board 5 are displaced together in the same phase. Therefore, the positional accuracy of the multiple boards 4 and 5 arranged in different directions can be improved. Then, when vibration or disturbance load occurs between the boards 4 and 5, the first connector 6 and the second connector 7 connected to each other vibrate together, and the mutual electrical connection is stabilized. Note that vibration refers to vibrations that occur when a vehicle equipped with the electronic device 1 of the embodiment is running, and are transmitted to the boards 4 and 5. Additionally, a disturbance load refers to a load that causes the boards 4 and 5 to move in different directions due to an external force that distorts or twists between the main body 2 side and the panel 3 side.

In addition, in the fixing bracket 8 of the embodiment, the base 8A is provided with a drawn portion 8Aa. Therefore, the rigidity of the base 8A of the fixing bracket 8 is increased by the drawn portion 8Aa, and the positional accuracy of the multiple substrates 4, 5 arranged in different directions can be further improved.

In addition, in the fixing bracket 8 of the embodiment, the engagement between the first claw portion 8B and the first recess 4C, and the engagement between the second claw portion 8C and the second recess 5C, regulate the relative movement between the first board 4 and the second board 5 in a first direction, which is the left-right direction. The fixing bracket 8 of the embodiment further includes a regulating means for regulating the relative movement between the first board 4 and the second board 5 in a second direction different from the first direction.

In the above-mentioned fixing bracket 8, the restricting means is composed of the tongue 8Ab, the screw 8G for fixing the tongue 8Ab to the first board 4, the abutment 8D, and the screw 8H for fixing the abutment 8D to the second board 5. As described above, the tongue 8Ab abuts against the lower surface 4B of the first board 4. The tongue 8Ab is fixed to the first board 4 by the screw 8G. Also, as described above, the abutment 8D abuts against the rear surface 5B of the second board 5. The abutment 8D is fixed to the second board 5 by the screw 8H. Therefore, the fixing bracket 8 restricts the relative movement between the first board 4 and the second board 5 in the vertical direction and the front-rear direction, which are the second direction, by the tongue 8Ab fixed to the first board 4 by the screw 8G and the abutment 8D fixed to the second board 5 by the screw 8H. As a result, the fixing bracket 8 of the embodiment can further improve the positional accuracy of multiple boards 4, 5 arranged in different directions.

Here, Figures 7 and 8 are plan views of other examples of the restricting means of the fixing bracket according to the embodiment.

The restricting means shown in FIG. 7 is composed of an abutment member 8J. The abutment member 8J is fixed to the main body 2 side. The main body 2 side includes, for example, the lower plate 2B, the right plate 2C, and the left plate 2D. The abutment member 8J is made of sheet metal and has an extension portion 8Ja extending forward from the main body 2 side and an abutment portion 8Jb formed by bending the front end of the extension portion 8Ja. The abutment member 8J has a front surface 8Jc facing forward at the abutment portion 8Jb where the front end of the extension portion 8Ja is bent in the vertical and horizontal directions. The abutment member 8J thus formed is abutted against the plate surface of the fixed plate 3D to which the second board 5 is fixed when the first connector 6 of the first board 4 and the second connector 7 of the second board 5 are connected to each other. Therefore, the fixing bracket 8 restricts the relative movement between the fixing plate 3D to which the second substrate 5 is fixed and the main body 2 to which the first substrate 4 is fixed in the second direction, the front-rear direction, by the abutting member 8J. As a result, the fixing bracket 8 of the embodiment can further improve the positional accuracy of the multiple substrates 4, 5 arranged in different directions. The abutting member 8J may be formed to protrude rearward from the fixing plate 3D. In this case, the abutting member 8J can be formed by bending a part of the fixing plate 3D rearward. The abutting member 8J protruding from the fixing plate 3D abuts against the front end of the first substrate 4, and restricts the relative movement between the fixing plate 3D to which the second substrate 5 is fixed and the main body 2 to which the first substrate 4 is fixed in the second direction, the front-rear direction.

The restricting means shown in FIG. 8 is composed of a first claw portion 8B. As described above, the first claw portion 8B engages with the first recess 4C formed in the first substrate 4, but is formed so as to abut against the rear end 4Ca, which is the back of the notch of the first recess 4C. When the first connector 6 of the first substrate 4 and the second connector 7 of the second substrate 5 are connected to each other, the first claw portion 8B abuts against the rear end 4Ca of the first recess 4C. Therefore, the fixing bracket 8 positions the first substrate 4 in the front-rear direction, which is the second direction, by the first claw portion 8B. As a result, the fixing bracket 8 of the embodiment can further improve the positional accuracy of the multiple substrates 4, 5 arranged in different directions. In addition, in the fixing bracket 8 shown in FIG. 8, the abutment portion 8D is provided at the front end of the base portion 8A, which is the front side of each first claw portion 8B. Therefore, in the fixing bracket 8 shown in FIG. 8, the abutment portion 8D abuts against the rear surface 5B of the second substrate 5, so that the first claw portion 8B abuts against the rear end 4Ca of the first recess 4C. As a result, the fixing bracket 8 of this embodiment can further improve the positional accuracy of multiple substrates 4, 5 arranged in different directions.

The wiring structure of the embodiment includes the above-mentioned fixing bracket 8, a first connector 6 provided on the part of the first board 4 fixed by the fixing bracket 8, and a second connector 7 provided on the part of the second board 5 fixed by the fixing bracket 8 and electrically connected to the first connector 6. Here, the second connector 7 extends rearward from the position where the second board 5 is fixed by the fixing bracket 8, which is the direction of the rear surface 5B of the second board 5, and the first connector 6 connects to the second connector 7 on the upper surface 4A, which is the back surface of the lower surface 4B where the first board 4 is fixed by the fixing bracket 8. In addition, the first connector 6 and the second connector 7 are located between the restricting means. Therefore, according to the wiring structure of the embodiment, the fixing bracket 8 can further improve the positional accuracy of the multiple boards 4, 5 arranged in different directions, and the electrical connection of the connectors 6, 7 provided on these boards 4, 5 can be stabilized.

The electronic device 1 of the embodiment also has the wiring structure described above. Therefore, according to the electronic device 1 of the embodiment, the electrical connection of the connectors 6, 7 provided on the multiple boards 4, 5 arranged in different directions can be stabilized, and the input and output of signals as the electronic device 1 can be stabilized.

Figure 9 is a flowchart of the assembly procedure for a substrate using a fixing bracket according to an embodiment.

3, as shown in FIG. 9, first, in step S1, the fixing bracket 8 is attached to the second board 5 to which the second connector 7 is attached. Next, in step S2, the second board 5 is attached to the fixing plate 3D via the support portion 10D. In step S2, the second claw portion 8C of the fixing bracket 8 is engaged with the second recessed portion 5C of the second board 5, and the abutment portion 8D is attached to the second board 5 with the screw 8H. Next, in step S3, the support plate 3C is attached to the fixing plate 3D via the support portion 10B. Next, in step S4, the right plate 2C and the left plate 2D of the main body portion 2 are attached to the lower plate 2B in advance. Then, this main body portion 2 side is attached to the support plate 3C via the right plate 2C and the left plate 2D. Next, in step S5, the first board 4 to which the first connector 6 is attached is slid forward so that the first connector 6 can be connected to the second connector 7 of the second board 5. As a result, the first connector 6 and the second connector 7 are connected. Next, in step S6, the fixing bracket 8 is attached to the first substrate 4. In step S6, the first claw portion 8B of the fixing bracket 8 is engaged with the first recessed portion 4C of the first substrate 4, and the tongue piece 8Ab is attached to the first substrate 4 with the screw 8G. Finally, in step S7, the first substrate 4 is attached to the lower plate 2B via the support portion 10C. The first substrate 4 does not have a positioning structure for attachment to the support portion 10C, but has an adjustment function that allows freedom of attachment by making the hole for attachment to the support portion 10C larger in diameter.

In this manner, in the assembly procedure of the board using the fixing bracket 8 according to the embodiment, the fixing bracket 8 is attached to the second board 5 to be attached to the panel section 3 side, then the first board 4 is added so that the first connector 6 is connected to the second connector 7 of the second board 5, the fixing bracket 8 is attached to the first board 4, and finally the first board 4 is attached to the main body section 2 side. The first board 4 and the second board 5 are positioned by the fixing bracket 8 with their connectors 6, 7 connected to each other, and this positioning is not restricted by the main body section 2 side or the panel section 3 side. In the conventional method that does not use the fixing bracket 8, the first board 4 is attached to the main body section 2 side, the second board 5 is attached to the panel section 3 side, and then the main body section 2 side and the panel section 3 side are attached while connecting the first connector 6 of the first board 4 and the second connector 7 of the second board 5, so that the positioning of the connection of each connector 6, 7 is restricted by the main body section 2 side or the panel section 3 side.
