以下、この発明をより詳細に説明するため、この発明を実施するための形態について、添付の図面に従って説明する。
実施の形態１．
図１は、この発明に係る基板組み付け構造を備える電子機器を示す斜視図である。図１に示す電子機器１は、この発明に係る基板組み付け構造を内部に有する電子機器であり、シャーシ３の天面を覆うカバー２、少なくとも２面（天面、前面など）が開口した箱状のシャーシ３およびシャーシ３の前面に設けられたパネル４を備える。その内部構成としては、図２に示すように、パネル４が裏面（シャーシ３の内部側の面）にパネル基板４ａを備えており、フロントシャーシ６を介してシャーシ３の前面に組み付けられる。Hereinafter, in order to describe the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
FIG. 1 is a perspective view showing an electronic apparatus having a board assembly structure according to the present invention. An electronic device 1 shown in FIG. 1 is an electronic device having a board assembly structure according to the present invention, and is a cover 2 that covers the top surface of the chassis 3, and a box shape in which at least two surfaces (the top surface, the front surface, etc.) are opened. The chassis 3 and the panel 4 provided on the front surface of the chassis 3 are provided. As shown in FIG. 2, the panel 4 includes a panel substrate 4 a on the back surface (surface on the inside of the chassis 3) and is assembled to the front surface of the chassis 3 via the front chassis 6.

また、シャーシ３の後面３Ａには、図２に示すように開口部３ａが形成されており、基板５は、当該基板５上に配置されたコネクタ７の外部との接続に供せられる側の端部が、シャーシ３の開口部３ａから外部に露出するようにシャーシ３内に組み付けられる。
コネクタ７は、基板５の実装面の端部に配置されて、当該コネクタ７の外部との接続に供せられる側の端部を除く部分（シャーシ３の内部側に露出する部分）がコネクタホルダ７ａによって覆われている。Further, an opening 3a is formed in the rear surface 3A of the chassis 3 as shown in FIG. 2, and the substrate 5 is provided on the side provided for connection to the outside of the connector 7 disposed on the substrate 5. The end portion is assembled in the chassis 3 so as to be exposed to the outside from the opening 3 a of the chassis 3.
The connector 7 is disposed at the end of the mounting surface of the substrate 5, and a portion (exposed to the inside of the chassis 3) excluding the end on the side used for connection to the outside of the connector 7 is a connector holder 7a.

なお、電子機器１では、基板５を、図３（ａ）に矢印で示すように、コネクタ７を配置した側をシャーシ３の後面３Ａに対して傾けながら当該後面３Ａに向けて導入し、コネクタ７の外部との接続に供せられる端部を開口部３ａに挿通させることにより、コネクタ７の上記端部が開口部３ａから外部に露出した状態でシャーシ３内に組み付けられる。
このとき、コネクタ７を配置した端部側に実装される電子部品８の高さ（基板５の実装面からの高さ）が、コネクタホルダ７ａを含むコネクタ７よりも高い場合、図３（ｂ）に示すように、電子部品８が後面３Ａに接触して破損する可能性がある。In the electronic device 1, as shown by an arrow in FIG. 3A, the board 5 is introduced toward the rear surface 3 </ b> A while the side on which the connector 7 is disposed is inclined with respect to the rear surface 3 </ b> A of the chassis 3. 7 is inserted into the opening 3a, so that the end of the connector 7 is assembled into the chassis 3 with the opening 3a exposed to the outside.
At this time, when the height of the electronic component 8 mounted on the end side where the connector 7 is disposed (the height from the mounting surface of the substrate 5) is higher than the connector 7 including the connector holder 7a, FIG. ), The electronic component 8 may come into contact with the rear surface 3A and be damaged.

つまり、図４に示すように、コネクタ７の外部との接続に供せられる側の端部を、シャーシ３の後面３Ａに形成した開口部３ａに挿通させるときに、基板５が、コネクタ７側が下がるように傾いているため、コネクタ７より高い電子部品８が、シャーシ３の後面３Ａに接触する。この場合、基板５をシャーシ３の後面３Ａに向けて無理に導入すると、当該接触により電子部品８が傾いて基板５との接合部が破損する恐れがある。   That is, as shown in FIG. 4, when the end of the connector 7 connected to the outside is inserted into the opening 3 a formed in the rear surface 3 </ b> A of the chassis 3, the board 5 is connected to the connector 7 side. The electronic component 8 higher than the connector 7 comes into contact with the rear surface 3 </ b> A of the chassis 3 because it is inclined so as to be lowered. In this case, if the board 5 is forcibly introduced toward the rear surface 3 </ b> A of the chassis 3, the electronic component 8 may be inclined due to the contact, and the joint with the board 5 may be damaged.

そこで、この発明では、図５（ａ）に示すように、従来のコネクタホルダ７ａの代わりにコネクタホルダ７Ａを使用する。コネクタホルダ７Ａは、図５（ｂ）（符号Ａを付した部分の拡大図）に示すように、コネクタ７の外部との接続に供せられる側の端部と同じ側の上部、すなわち基板５をシャーシ３内に組み付けたときに後面３Ａ側を向く上部に、電子部品８よりも基板５の端部に近い位置にあり、かつ基板５の実装面からの高さが電子部品８よりも高くなるように形成した当たり形状部９を備える。   Therefore, in the present invention, as shown in FIG. 5A, a connector holder 7A is used instead of the conventional connector holder 7a. As shown in FIG. 5B (enlarged view of a portion denoted by reference symbol A), the connector holder 7A is an upper portion on the same side as the end portion provided for connection to the outside of the connector 7, that is, the substrate 5 Is mounted on the rear surface 3A side when assembled in the chassis 3 and is closer to the end of the substrate 5 than the electronic component 8, and the height from the mounting surface of the substrate 5 is higher than that of the electronic component 8. The contact shape part 9 formed so that it becomes is provided.

コネクタ７の外部との接続に供せられる側の端部が開口部３ａから外部に露出するように当該基板５をシャーシ３内に組み付けるときに、従来と同様に、コネクタ７側が下がるように傾けながらシャーシ３内の後面３Ａに向けて基板５を導入していくと、この発明では、図６に示すように、電子部品８よりも先に当たり形状部９がシャーシ３の後面３Ａに接触する。これにより、電子部品８がシャーシ３の後面３Ａに直接接触することがなく、破損を防止できる。なお、図５（ａ）のように、１枚の板材を折り曲げてコネクタホルダ７Ａを形成することで、この発明に係る基板組み付け構造を簡易な構成で実現することができる。   When assembling the substrate 5 in the chassis 3 so that the end of the connector 7 connected to the outside is exposed to the outside from the opening 3a, the connector 7 is inclined so that the connector 7 side is lowered as in the conventional case. However, when the substrate 5 is introduced toward the rear surface 3A in the chassis 3, the contact portion 9 comes into contact with the rear surface 3A of the chassis 3 before the electronic component 8 as shown in FIG. Thereby, the electronic component 8 does not directly contact the rear surface 3A of the chassis 3 and can be prevented from being damaged. As shown in FIG. 5A, the board assembly structure according to the present invention can be realized with a simple configuration by bending one plate material to form the connector holder 7A.

また、図７（ａ）、図７（ｂ）（符号Ｂを付した部分の拡大図）に示すように、コネクタホルダ７Ａの実装面側の端部には、係合凸部１０ａ，１０ｂと、孔部１２が形成された取り付け板部１１が設けられる。また、基板５には、実装されたコネクタ７の周囲に孔部１３ａ，１３ｂ，１４ａが形成されている。コネクタホルダ７Ａの取り付けは、まず、基板５の孔部１３ａ，１３ｂに係合凸部１０ａ，１０ｂを挿入して位置決めを行い、ねじを孔部１２および孔部１４ａに挿通させてねじ止めする。   Further, as shown in FIGS. 7A and 7B (enlarged view of the portion denoted by reference symbol B), the end portions on the mounting surface side of the connector holder 7A have engagement convex portions 10a and 10b. A mounting plate portion 11 in which a hole portion 12 is formed is provided. Further, holes 13 a, 13 b, and 14 a are formed in the substrate 5 around the mounted connector 7. To attach the connector holder 7A, first, the engaging projections 10a and 10b are inserted into the holes 13a and 13b of the substrate 5 for positioning, and screws are inserted into the holes 12 and 14a to be screwed.

以上のように、この実施の形態１によれば、コネクタ７を覆うように設けたコネクタホルダ７Ａと、コネクタホルダ７Ａに形成され、基板５のコネクタ７が配置された側に実装された電子部品８より当該基板５の端面に近い位置にあり、かつ当該基板５の実装面からの高さが電子部品８よりも高い当たり形状部９とを備える。このように構成することで、組み付け時に基板５上の電子部品８がシャーシ３側の面に接触することを防止できる。   As described above, according to the first embodiment, the connector holder 7A provided so as to cover the connector 7 and the electronic component formed on the connector holder 7A and mounted on the side of the board 5 where the connector 7 is disposed. 8 and a contact portion 9 that is closer to the end surface of the substrate 5 and that has a height from the mounting surface of the substrate 5 higher than that of the electronic component 8. By comprising in this way, it can prevent that the electronic component 8 on the board | substrate 5 contacts the surface by the side of the chassis 3 at the time of an assembly | attachment.

また、この実施の形態１によれば、電子機器１が、上記の基板組み付け構造を備えるので、上記と同様の効果が得られる電子機器１を提供することができる。   Moreover, according to this Embodiment 1, since the electronic device 1 is provided with said board | substrate assembly | attachment structure, the electronic device 1 with the same effect as the above can be provided.

なお、本発明はその発明の範囲内において、実施の形態の任意の構成要素の変形、もしくは実施の形態の任意の構成要素の省略が可能である。   In the present invention, any component of the embodiment can be modified or any component of the embodiment can be omitted within the scope of the invention.

この発明に係る基板組み付け構造は、組み付け時に基板上の電子部品がシャーシ側の面に衝突することを防止できるので、小型化により組み付け時にシャーシの側面と基板の端部との距離が近くなる可能性がある車載用の電子機器に好適である。   The board assembly structure according to the present invention can prevent the electronic components on the board from colliding with the surface on the chassis side during the assembly, so that the distance between the side surface of the chassis and the edge of the board can be reduced during the assembly due to downsizing. This is suitable for a vehicle-mounted electronic device.
