Description

この発明は、電子機器のシャーシに締結する回路基板の締結部構造に関するものである。   The present invention relates to a fastening part structure of a circuit board that is fastened to a chassis of an electronic device.

一般に電子機器の回路基板は、その一部がシャーシにネジで締結されているが、その締結に際しては、回路基板の部品実装面もしくは回路パターン形成面とシャーシとを所定の間隔で離して保持するように前記回路基板とシャーシとをネジで締結する構造としているのが殆どである。このような従来の回路基板の締結部構造として、前記シャーシの基板締結部位に凹状部を絞り加工し、この凹状部の先端面（底部）を回路基板に当接させ、この状態で前記シャーシの凹状部の底部と回路基板とをネジで締結する構成としたものは既に知られている。ここで、前記シャーシの凹状部は、この凹状部に収納されるネジの頭部の径よりも底部面積が大きくなるように形成され、前記シャーシと回路基板との締結状態では、前記凹状部の底面全体が回路基板上に接合するようになっている。   In general, a part of a circuit board of an electronic device is fastened to a chassis with a screw. At the time of fastening, a component mounting surface or circuit pattern forming surface of the circuit board and the chassis are held apart at a predetermined interval. In most cases, the circuit board and the chassis are fastened with screws. As such a conventional circuit board fastening portion structure, a concave portion is drawn at the board fastening portion of the chassis, and the front end surface (bottom portion) of the concave portion is brought into contact with the circuit board. A configuration in which the bottom of the concave portion and the circuit board are fastened with screws is already known. Here, the concave portion of the chassis is formed so that the bottom area is larger than the diameter of the head of the screw housed in the concave portion, and when the chassis and the circuit board are fastened, the concave portion of the chassis is formed. The entire bottom surface is joined to the circuit board.

なお、上記先行技術は当業者一般に知られた技術であって、文献公知発明に係るものではない。   The above prior art is a technique generally known to those skilled in the art, and does not relate to a known literature invention.

また、他の従来例に係る回路基板の締結部構造として、シャーシ（筐体）の基板締結部位に断面凸形状の基板座面を絞り加工すると共に、その基板座面にバーリング加工を施してネジ穴を形成し、前記基板座面上に当接支承させた回路基板とネジ頭部と間にスプリングワッシャと平ワッシャを介在させ、それらのワッシャを介して前記シャーシと回路基板とを前記ネジ穴に螺合したネジで締結固定する構成としたものも既に知られている（例えば、特許文献１参照）。   In addition, as a fastening part structure of a circuit board according to another conventional example, a board seating surface having a convex cross section is drawn at a board fastening part of a chassis (housing), and a burring process is performed on the board seating surface to screw A spring washer and a flat washer are interposed between the circuit board and the screw head formed in contact with and supported on the board seat surface, and the chassis and circuit board are connected to the screw hole via the washers. There is already known a configuration in which a screw is fastened and fixed with a screw (see, for example, Patent Document 1).

特開２００１−３３２８７８号公報（段落〔００５７〕、図２）JP 2001-332878 (paragraph [0057], FIG. 2)

従来の回路基板の締結構造は以上のように構成されているので、シャーシの基板締結部位に形成されてネジ頭部が収納される大きさの凹状部の底面と回路基板との接触面積が大きくなり、その分、前記回路基板の有効面積が減少するという課題があった。すなわち、前記シャーシにネジ頭部の径より大きな底部面積に形成された凹状部の底面と回路基板とが隙間なく接触しているため、前記回路基板における前記凹状部底面との接触領域に回路パターンを形成したり実装部品を配置したりすることができずに回路基板の有効面積が減少し、電子機器の小型化に支障を来すという課題があった。   Since the conventional circuit board fastening structure is configured as described above, the contact area between the bottom surface of the concave portion formed in the board fastening portion of the chassis and accommodating the screw head and the circuit board is large. Therefore, there is a problem that the effective area of the circuit board is reduced accordingly. That is, since the bottom surface of the concave portion formed on the chassis with a bottom area larger than the diameter of the screw head and the circuit board are in contact with each other without a gap, a circuit pattern is formed in the contact area between the bottom surface of the concave portion on the circuit board. There is a problem in that the effective area of the circuit board is reduced because it is not possible to form the mounting parts or to arrange the mounting parts, thereby hindering the downsizing of the electronic device.

また、特許文献１においても、シャーシに絞り加工された基板座面に回路基板が隙間なく接触し、当該回路基板上にも平ワッシャが隙間なく接触していることから、前述した従来の回路基板の締結構造の場合と同様に、前記回路基板におけるシャーシの基板座面および平ワッシャとの接触領域に回路パターンを形成したり実装部品を配置したりすることができずに回路基板の有効面積が減少し、しかも、ネジ頭部と回路基板との間には前記平ワッシャとスプリングワッシャを介在させなければならず、このため、部品点数が多くなってコスト高になるという課題があった。 Also in Patent Document 1, since the circuit board is in contact with the board seating surface drawn to the chassis without any gap, and the flat washer is in contact with the circuit board without any gap, the above-described conventional circuit board is also provided. As in the case of the fastening structure, the circuit board has an effective area without being able to form a circuit pattern or dispose a mounting component in the contact area of the circuit board with the board seating surface of the chassis and the flat washer. In addition, the flat washer and the spring washer have to be interposed between the screw head and the circuit board. For this reason, there is a problem that the number of parts increases and the cost increases.

この発明は上記のような課題を解決するためになされたもので、シャーシに回路基板締結用の凹状部が形成されたものでありながら、その凹状部の底部と回路基板との間で回路基板の有効面積を増大させることができる回路基板の締結部構造を得ることを目的とする。   The present invention has been made to solve the above-described problems.

In the part structure, the fastening member is inserted so as to protrude toward the circuit board side, and the tip is in contact with the ground member having a plurality of ground terminals on the circuit board so as to electrically connect the circuit board and the chassis. the bottom integrally formed a cylindrical portion, a gap portion provided between the bottom and the circuit board of the concave portion is brought into contact with the distal end to the circuit board, to so that the earth terminal is arranged in the region of the air gap It is composed.

In the part structure, a fastening member is inserted into a grounding member having a plurality of grounding terminals mounted on the circuit board so as to protrude toward the chassis side, and the tip abuts against the bottom of the concave portion to A cylindrical part is integrally formed on the grounding member so that it can be connected, and the tip is brought into contact with the chassis to provide a gap between the bottom of the concave part and the circuit board. are those configured to so that.

Furthermore, since a member separate from the chassis and the circuit board is not required to form the gap, there is an effect that the number of parts can be reduced and the cost can be reduced.

この発明によれば、シャーシに回路基板締結用の凹状部を形成し、この凹状部の底部を介して回路基板とシャーシとを締結部材で締結してなる回路基板の締結部構造において、回路基板上に実装された複数のアース端子を有するアース部材にシャーシ側に突出して締結部材が挿入されるとともに、先端が凹状部の底部に当接して回路基板とシャーシとを電気的に接続するようアース部材に筒状部を一体形成し、先端をシャーシに当接させて凹状部の底部と回路基板との間に空隙部を設け、この空隙部の領域にアース端子が配置されるように構成したので、前記アース部材と一体の筒状部によって、前記凹状部の底部と回路基板との間に形成される空隙部に前記アース部材を配置することができ、したがって、前記回路基板の有効面積が増大するという効果がある。また、前述のようにアース部材と一体の筒状部によって前記空隙部を形成することができ、その空隙部を形成するために、前記アース部材とは別体の部材を必要としないので、部品点数の減少およびコスト低減が図れるという効果がある。 According to the present invention, in the fastening part structure of the circuit board formed by forming the concave part for fastening the circuit board in the chassis and fastening the circuit board and the chassis with the fastening member through the bottom part of the concave part, The ground member having a plurality of ground terminals mounted thereon projects into the chassis side to be inserted into the fastening member , and the tip is in contact with the bottom of the concave portion so as to electrically connect the circuit board and the chassis. integrally formed a cylindrical portion member, a gap portion provided between the bottom and the circuit board of the concave portion is brought into contact with the tip to the chassis, the ground terminal in the region of the gap portion is configured to so that is placed Therefore, the ground member can be disposed in the gap formed between the bottom of the concave portion and the circuit board by the cylindrical portion integral with the ground member, and thus the effective area of the circuit board is reduced.

以下、この発明をより詳細に説明するために、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。
参考例．
図１はこの発明の参考例による回路基板の締結部構造を示す断面図、図２は図１のＡ−Ａ線に沿った断面矢視図である。
図１に示す回路基板の締結部構造は、例えば車載用の電子機器における筐体１の蓋部材からなるシャーシ２と、前記筐体１内に収納された回路基板３とを締めネジ（締結部材）４で締結した概要構成となっている。さらに詳しく説明すると、前記筐体１の底部にはネジ孔部５ａを有する基板支持用のポスト５が立設されている。一方、前記回路基板３には、前記ポスト５のネジ孔部５ａに連通させるためのネジ挿通穴３ａが設けられている。 Hereinafter, in order to explain the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Reference example .
FIG. 1 is a cross-sectional view showing a fastening structure of a circuit board according to a reference example of the present invention, and FIG. 2 is a cross-sectional view taken along the line AA in FIG.
The fastening part structure of the circuit board shown in FIG. 1 is a fastening screw (fastening member) that connects, for example, a chassis 2 formed of a lid member of a housing 1 in an in-vehicle electronic device and a circuit board 3 housed in the housing 1. ) It is the general composition concluded in 4. More specifically, a substrate support post 5 having a screw hole 5a is erected on the bottom of the housing 1. On the other hand, the circuit board 3 is provided with a screw insertion hole 3 a for communicating with the screw hole portion 5 a of the post 5.

すなわち、前記回路基板３は、そのネジ挿通穴３ａが前記ポスト５のネジ孔部５ａに連通する位置に位置決めされて当該ポスト５上に載置されるようになっている。そして、前記ポスト５上に載置された回路基板３と、この回路基板３の上部に配置されたシャーシ２とを、前記ポスト５のネジ孔部５ａに螺合させた締めネジ４で締結固定するようになっている。   That is, the circuit board 3 is placed on the post 5 in a position where the screw insertion hole 3 a communicates with the screw hole portion 5 a of the post 5. Then, the circuit board 3 placed on the post 5 and the chassis 2 disposed on the circuit board 3 are fastened and fixed with a fastening screw 4 screwed into the screw hole 5a of the post 5. It is supposed to be.

次に、前記シャーシ２の詳細について説明すると、当該シャーシ２における基板締結部位には、テーパー状の凹状部２ａと、この凹状部２ａの底部中心から前記回路基板３側に向かって突出する締めネジ挿入用の筒状部２ｂとがバーリング加工によって一体形成されている。ここで、前記凹状部２ａは、その底部が前記締めネジ４の頭部４ａの座面を形成する大きさに形成され、前記筒状部２ｂは締めネジ４のネジ軸部を挿入可能な内径でかつ回路基板３のネジ挿通穴３ａよりも大径の外径に形成されている。したがって、前記締めネジ４によるシャーシ２と回路基板３との締結時には、前記筒状部２ｂの先端が回路基板３上に当接して前記凹状部２ａの底部と回路基板３との間に空隙部Ｓが形成されるようになっている。   Next, the details of the chassis 2 will be described. The board fastening portion in the chassis 2 includes a tapered concave portion 2a and a fastening screw that protrudes from the center of the bottom of the concave portion 2a toward the circuit board 3 side. The cylindrical portion 2b for insertion is integrally formed by burring. Here, the concave portion 2a is formed in such a size that the bottom portion thereof forms a seating surface of the head portion 4a of the tightening screw 4, and the cylindrical portion 2b has an inner diameter into which the screw shaft portion of the tightening screw 4 can be inserted. In addition, the outer diameter of the circuit board 3 is larger than that of the screw insertion hole 3a. Therefore, when the chassis 2 and the circuit board 3 are fastened by the fastening screw 4, the tip of the cylindrical part 2 b abuts on the circuit board 3, and a gap is formed between the bottom of the concave part 2 a and the circuit board 3. S is formed.

次に動作について説明する。ここでは、回路基板３とシャーシ２の組立締結について説明する。
筐体１内のポスト５上に回路基板３を位置決め載置した後、その回路基板３上にシャーシ２を位置決め配置することで、前記ポスト５のネジ孔部５ａと回路基板３のネジ挿通穴３ａとシャーシ２の筒状部２ｂとを連通させる。この状態で前記シャーシ２の凹状部２ａ内から筒状部２ｂおよび回路基板３のネジ挿通穴３ａを介して前記ポスト５のネジ孔部５ａに締めネジ４を螺合・緊締することにより、前記ポスト５上に回路基板３とシャーシ２が締結固定される。その締結状態においては、前記シャーシ２の凹状部２ａの底部から突出している筒状部２ｂの先端が前記回路基板３上に当接することにより、前記シャーシ２の凹状部２ａの底部と回路基板３との間に空隙部Ｓが形成される。 Next, the operation will be described. Here, assembly fastening of the circuit board 3 and the chassis 2 will be described.
After positioning the circuit board 3 on the post 5 in the housing 1 and positioning the chassis 2 on the circuit board 3, the screw hole 5a of the post 5 and the screw insertion hole of the circuit board 3 are positioned. 3a and the cylindrical part 2b of the chassis 2 are connected. In this state, the fastening screw 4 is screwed and tightened from the inside of the recessed portion 2a of the chassis 2 to the screw hole portion 5a of the post 5 through the cylindrical portion 2b and the screw insertion hole 3a of the circuit board 3, thereby The circuit board 3 and the chassis 2 are fastened and fixed on the post 5. In the fastened state, the tip of the cylindrical portion 2b protruding from the bottom of the concave portion 2a of the chassis 2 abuts on the circuit board 3 so that the bottom of the concave portion 2a of the chassis 2 and the circuit board 3 A gap S is formed between the two.

以上説明した参考例によれば、シャーシ２の回路基板締結部位に締めネジ４の頭部４ａを収納可能な凹状部２ａと、この凹状部２ａの底部からポスト５上の回路基板３側に突出して前記締めネジ４が挿入される筒状部２ｂとを一体形成し、この筒状部２ｂの先端を前記回路基板３上に当接させて前記凹状部２ａの底部と前記回路基板３との間に空隙部Ｓが形成されるように構成したので、前記凹状部２ａの底部全面を回路基板３上に接触させていた従来例の場合に比べて前記空隙部Ｓにより回路基板３の有効面積が増大するという効果がある。すなわち、前記シャーシ２の凹状部２ａの底部と回路基板３との間に前記筒状部２ｂで形成された空隙部Ｓの領域に配置する回路パターンを回路基板３上に形成したり、当該回路基板３上に実装された高さのある電子部品等の実装部品を前記空隙部Ｓに配置したりすることができ、回路パターン設計上の自由度が向上し、電子機器の小型化に寄与できるという効果がある。さらには、前記空隙部Ｓにアース部材を配置することも可能で、この場合、そのアース部材と前記シャーシ２とを前記筒状部２ｂによって電気的に接続することもできるという効果がある。 According to the reference example described above, the concave portion 2a capable of accommodating the head 4a of the fastening screw 4 at the circuit board fastening portion of the chassis 2, and the bottom of the concave portion 2a protrudes toward the circuit board 3 on the post 5. The cylindrical portion 2b into which the fastening screw 4 is inserted is integrally formed, and the tip of the cylindrical portion 2b is brought into contact with the circuit board 3 so that the bottom of the concave portion 2a and the circuit board 3 Since the gap S is formed between them, the effective area of the circuit board 3 is reduced by the gap S compared to the conventional example in which the entire bottom of the concave portion 2a is in contact with the circuit board 3. Has the effect of increasing. That is, a circuit pattern arranged in the space S formed by the cylindrical portion 2b between the bottom of the concave portion 2a of the chassis 2 and the circuit board 3 is formed on the circuit board 3, or the circuit Mounting components such as electronic components having a height mounted on the substrate 3 can be arranged in the gap S, and the degree of freedom in circuit pattern design can be improved, contributing to downsizing of electronic devices. There is an effect. Furthermore, it is also possible to arrange a grounding member in the gap S, and in this case, there is an effect that the grounding member and the chassis 2 can be electrically connected by the cylindrical part 2b.
