Description

本考案は、プリント基板の固定する治具と治具を使用した装置に関する。 The present invention relates to a jig for fixing a printed circuit board and an apparatus using the jig.

高さの異なる電子部品をプリント基板上に実装する際、子基板に高さの低い部品を実装し、主基板上に鉛直方向に実装すると、空間のスペースを有効に活用でき小型化が可能となる。
しかし、子基板は主基板と接する１方向のみで固定されるため、機械的な強度が弱い。特に子基板にコネクタを実装した場合は、コネクタの挿抜の際の利便性からコネクタを上部に配置すると良いが、上部は位置すると挿抜の際に機械的ストレスが子基板に加わり、子基板と主基板の接続部の破損または、子基板自体の破損等の恐れがある。
そこで特許文献１は、複数の子基板の上部にホルダを設け、子基板を固定する治具と、固定字具を用いた装置を提案する。 When mounting electronic components with different heights on a printed circuit board, mounting low-level components on the slave board and mounting them on the main board in the vertical direction enables effective use of space and enables miniaturization. Become.
However, since the daughter board is fixed only in one direction in contact with the main board, the mechanical strength is weak. In particular, when a connector is mounted on the sub board, it is better to place the connector on the top for convenience when inserting and removing the connector. However, if the upper part is located, mechanical stress is applied to the sub board when inserting and removing. There is a risk of damage to the connection part of the board or damage to the child board itself.
Therefore, Patent Document 1 proposes an apparatus using a jig provided with a holder on the top of a plurality of sub-boards and fixing the sub-board, and a fixing tool.

特許文献１は、子基板をホルダで固定する。子基板の突起部をホルダの挿通孔に挿通するので、カバーを取り付けることで確実な固定とすることができる。
しかし、専用のホルダを必要とする。また、カバーを装着することで確実に固定されるので、カバーを外した状態で行うコネクタの挿抜時の機械ストレスに対しては十分でない。本考案は、子基板に実装されたコネクタを挿抜する際の機械的ストレスを軽減ためのプリンt基板の固定具であり、容易に作製できる固定具を提案する。 In Patent Document 1, the daughter board is fixed with a holder. Since the protrusion of the sub board is inserted into the insertion hole of the holder, the cover can be securely fixed.
However, a dedicated holder is required. In addition, since the cover is securely fixed by attaching the cover, it is not sufficient against mechanical stress when the connector is inserted and removed with the cover removed. The present invention proposes a fastener that can be easily manufactured as a fastener for a printed circuit board for reducing mechanical stress when a connector mounted on a daughter board is inserted and removed.

そこで本考案は、主基板上に垂直方向に配置され、実装されたコネクタの近傍に第１のスリットを備える子基板と、前記主基板上に垂直方向に配置され、第２のスリットを備える板状部材とを備える電子装置において、第１のスリットに挿入される第３のスリットと、第２のスリットに挿入される第４のスリットを備え、子基板と板状部材を固定するための板状の固定部材を提案する。固定部材は、導電部を有しないプリント基板であり、子基板が組立完了後分離される捨て基板を用いる。 In view of this, the present invention provides a sub-board that is vertically arranged on the main board and has a first slit in the vicinity of the mounted connector, and a board that is vertically arranged on the main board and has the second slit. A plate for fixing a daughter board and a plate-shaped member, comprising: a third slit inserted into the first slit; and a fourth slit inserted into the second slit. A fixed member is proposed. The fixing member is a printed circuit board that does not have a conductive portion, and uses a discarded board from which the sub board is separated after the assembly is completed.

本考案によると、子基板が組立完了後分離される捨て基板を利用したプリント基板の固定具を用いて、子基板のスリットと固定部材のスリットが互いに挿入されて子基板を固定するので、子基板に実装したコネクタの挿抜による機械ストレスを容易に軽減することができる。 According to the present invention, the child board is fixed by inserting the slit of the child board and the slit of the fixing member into each other using the printed board fixing tool using the discarded board from which the child board is separated after the assembly is completed. Mechanical stress due to insertion / extraction of the connector mounted on the board can be easily reduced.

本考案の実施例を図１から図３を用いて説明する。
図１は本考案の実施例を示す斜視図である。主基板１が水平に配置され、主基板１上に、各種の電子部品と共に、子基板２と子基板３が主基板１に対して垂直方向に配置される。子基板には各種電子部品と共にコネクタ５およびコネクタ６が実装される。また、子基板２は接続部材７および接続部材８によって主基板１にはんだ付けされる。子基板３は図示されないが同じ方法で主基板１にはんだ付けされる。板状の固定部材４で子基板２および子基板３を連結する。 An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing an embodiment of the present invention. The main board 1 is arranged horizontally, and the sub board 2 and the sub board 3 are arranged on the main board 1 along with various electronic components in a direction perpendicular to the main board 1. A connector 5 and a connector 6 are mounted together with various electronic components on the slave board. Further, the sub board 2 is soldered to the main board 1 by the connecting member 7 and the connecting member 8. The sub board 3 is soldered to the main board 1 by the same method although not shown. The sub board 2 and the sub board 3 are connected by the plate-like fixing member 4.

子基板２は図２に示すように、コネクタ５およびコネクタ６の近傍にスリット９を備える。同様に子基板３には、子基板２の実装面に対し垂直方向でスリット９に対応する位置にスリット１０を備える。固定部材４は図３に示すように、スリット９およびスリット１０の対応する位置にスリット１１およびスリット１２を備える。この固定部材４を、スリット１１とスリット９を互いに挿入し、スリット１２とスリット１０が互いに挿入するように装着する。これによって、子基板２と子基板３が互いに固定され、コネクタ５またはコネクタ６を挿雑する際にも、子基板に対する機械的ストレスを軽減することができる。それぞれのスリットは子基板２または子基板３の厚さに合わせて決定され、容易に外れない程度の長さにする。本実施例ではスリットの長さを５ｍｍとしたが、コネクタの構造、子基板の大きさに応じて長さは変更する。また固定部材４は子基板から突き出ない寸法にする。このため、固定部材４が不用意にはづれることは少ない。また、子基板３は主基板１にねじ止めされているとより確実に子基板２が固定される。 As shown in FIG. 2, the sub board 2 includes a slit 9 in the vicinity of the connector 5 and the connector 6. Similarly, the sub board 3 includes a slit 10 at a position corresponding to the slit 9 in a direction perpendicular to the mounting surface of the sub board 2. As shown in FIG. 3, the fixing member 4 includes a slit 11 and a slit 12 at positions corresponding to the slit 9 and the slit 10. The fixing member 4 is mounted so that the slit 11 and the slit 9 are inserted into each other and the slit 12 and the slit 10 are inserted into each other. As a result, the child board 2 and the child board 3 are fixed to each other, and mechanical stress on the child board can be reduced even when the connector 5 or the connector 6 is inserted. Each slit is determined in accordance with the thickness of the child substrate 2 or the child substrate 3 and has a length that does not easily come off. In this embodiment, the length of the slit is 5 mm, but the length is changed according to the structure of the connector and the size of the sub board. The fixing member 4 is dimensioned so as not to protrude from the sub board. For this reason, the fixing member 4 is less likely to be carelessly touched. Further, when the daughter board 3 is screwed to the main board 1, the daughter board 2 is more securely fixed.

銅はくを取り除いたプリント基板は、絶縁材なので固定部材に適する。複数のプリント基板を面付けする場合、不要な部分ができる。実施例では子基板２の面付けを図４とした。子基板２の周囲にはんだ付けの際に基板を保持するための捨て基板が配置される。この部分は実装完了後は分割して廃棄される。この捨て基板の部分を利用して固定部材４を作る。固定部材４は銅はくを剥離しておくことで最適な固定部材となる。 Since the printed circuit board from which the copper foil has been removed is an insulating material, it is suitable as a fixing member. When imposing a plurality of printed circuit boards, unnecessary portions are formed. In the example, the imposition of the sub board 2 is shown in FIG. A waste board for holding the board at the time of soldering is arranged around the sub board 2. This part is divided and discarded after mounting is completed. The fixing member 4 is made using this discarded substrate portion. The fixing member 4 becomes an optimal fixing member by peeling off the copper foil.

実施例では子基板３にはコネクタが実装されないが、子基板３にコネクタがあっても良い。子基板２と同様にコネクタの挿抜時の機械的ストレスを軽減できる。また、子基板３は電子部品を実装する子基板ではなく、半導体部品を放熱するために主基板１上に実装した放熱板でも良い。いづれも同様の効果を奏する。 In the embodiment, no connector is mounted on the sub board 3, but the sub board 3 may have a connector. Similar to the sub-board 2, mechanical stress when the connector is inserted / removed can be reduced. Further, the sub board 3 is not a sub board on which electronic components are mounted, but may be a heat radiating plate mounted on the main board 1 in order to radiate semiconductor components. Both have the same effect.

本考案は、主基板に子基板を垂直方向に実装する場合のプリント基板の固定具として最適である。 The present invention is most suitable as a printed board fixing tool when a sub board is mounted on a main board in a vertical direction.
