以下、この発明の各実施の形態を図に基づいて説明するが、各図において、同一または相当の部材、部位については、同一符号を付して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding members and parts will be described with the same reference numerals.

実施の形態１．
図１はこの発明の実施の形態１に係る基板取外し治具を示す側面図である。図において、基板取外し治具は、基板１が固定されたＰＣＢサポート（基板固定具）２に取り付けられる基板取外し本体３と、作業者に把持される把持部４と、基板取外し本体３と把持部４とを連結する連結棒５と、基板１に取り付けられるキャップ部材６とを備えている。 Embodiment 1 FIG.
FIG. 1 is a side view showing a substrate removal jig according to Embodiment 1 of the present invention. In the figure, the substrate removal jig includes a substrate removal body 3 attached to a PCB support (substrate fixture) 2 to which the substrate 1 is fixed, a grip portion 4 gripped by an operator, a substrate removal body 3 and a grip portion. 4 and a cap member 6 attached to the substrate 1.

基板１には、複数の取付孔１１が形成されている。取付孔１１は、基板１を貫通して形成されている。取付孔１１の径方向についての寸法Ａは、予め設定された値となっている。基板１としては、エレベータの制御基板、火災報知機の制御基板、エアコンの制御基板などが挙げられる。   A plurality of mounting holes 11 are formed in the substrate 1. The attachment hole 11 is formed through the substrate 1. The dimension A in the radial direction of the mounting hole 11 is a preset value. Examples of the board 1 include an elevator control board, a fire alarm control board, and an air conditioner control board.

ＰＣＢサポート２は、取付孔１１の数に対応して配置されている。ＰＣＢサポート２は、軸部２１と、軸部２１の先端部に設けられ、径方向に弾性変形可能な矢尻部２２と、矢尻部２２よりも基端部側の軸部２１の部分に設けられ、矢尻部２２に対向する脚部２３とを有している。矢尻部２２は、径方向に押圧されていない状態では、径方向の寸法が、取付孔１１よりも大きくなっている。また、矢尻部２２は、径方向に押圧されることにより、径方向の寸法が取付孔１１よりも小さくなるようになっている。基板１は、取付孔１１に矢尻部２２が挿入されて矢尻部２２と脚部２３との間に基板１が挟まれることにより、ＰＣＢサポート２に固定される。ＰＣＢサポート２は、土台７に固定されている。   The PCB support 2 is arranged corresponding to the number of mounting holes 11. The PCB support 2 is provided at the shaft portion 21, the tip end portion of the shaft portion 21, and an arrowhead portion 22 that can be elastically deformed in the radial direction, and a portion of the shaft portion 21 that is proximal to the arrowhead portion 22. And a leg portion 23 facing the arrowhead portion 22. In the state where the arrowhead part 22 is not pressed in the radial direction, the dimension in the radial direction is larger than that of the mounting hole 11. Further, the arrowhead 22 is pressed in the radial direction so that the radial dimension is smaller than that of the mounting hole 11. The substrate 1 is fixed to the PCB support 2 by inserting the arrowhead portion 22 into the mounting hole 11 and sandwiching the substrate 1 between the arrowhead portion 22 and the leg portion 23. The PCB support 2 is fixed to the base 7.

基板取外し本体３は、矢尻部２２が挿入される筒部３１と、筒部３１に挿入された矢尻部２２が取付孔１１から引き抜かれる方向に押圧する押出部３２とを備えている。筒部３１は、内周面の径方向の寸法Ｂが、取付孔１１における径方向の寸法Ａよりも僅かに小さくなっている。これにより、筒部３１は、筒部３１に矢尻部２２が挿入されることにより、矢尻部２２が取付孔１１を通過可能となるように、矢尻部２２を径方向について収縮させる。また、筒部３１は、外周面の径方向の寸法Ｃが、取付孔１１における径方向の寸法Ａよりも僅かに大きくなっている。これにより、筒部３１が取付孔１１に挿入されることが防止される。   The substrate removal main body 3 includes a cylindrical portion 31 into which the arrowhead portion 22 is inserted, and an extrusion portion 32 that presses the arrowhead portion 22 inserted into the cylindrical portion 31 in a direction in which it is pulled out from the mounting hole 11. In the cylindrical portion 31, the radial dimension B of the inner peripheral surface is slightly smaller than the radial dimension A of the mounting hole 11. Thereby, the cylinder part 31 shrinks the arrowhead part 22 about radial direction so that the arrowhead part 22 can pass the attachment hole 11 by the arrowhead part 22 being inserted in the cylinder part 31. Further, the cylindrical portion 31 has a radial dimension C of the outer peripheral surface that is slightly larger than the radial dimension A of the mounting hole 11. Thereby, the cylindrical portion 31 is prevented from being inserted into the mounting hole 11.

押出部３２は、筒部３１の矢尻部２２が挿入される開口部とは反対側の開口部を覆うように筒部３１に設けられている。この例では、筒部３１と押出部３２とが一体に形成されている。筒部３１の軸方向についての寸法Ｄは、筒部３１により収縮した状態の矢尻部２２における筒部３１の軸方向についての寸法よりも小さくなっている。これにより、筒部３１により矢尻部２２が収縮した状態で、筒部３１の先端部を基板１に当接させることにより、押出部３２は、矢尻部２２を取付孔１１から押し出される方向に押圧する。   The pushing part 32 is provided in the cylinder part 31 so that the opening part on the opposite side to the opening part into which the arrowhead part 22 of the cylinder part 31 is inserted may be covered. In this example, the cylinder part 31 and the extrusion part 32 are integrally formed. The dimension D in the axial direction of the cylindrical part 31 is smaller than the dimension in the axial direction of the cylindrical part 31 in the arrowhead part 22 in a state contracted by the cylindrical part 31. Thus, the pushing portion 32 presses the arrowhead portion 22 in the direction in which the arrowhead portion 22 is pushed out from the mounting hole 11 by bringing the tip portion of the tube portion 31 into contact with the substrate 1 while the arrowhead portion 22 is contracted by the tube portion 31. To do.

キャップ部材６は、矢尻部２２が引き抜かれた取付孔１１を塞ぐようになっている。キャップ部材６は、例えば、シリコンゴムから構成されている。   The cap member 6 is configured to close the attachment hole 11 from which the arrowhead portion 22 has been pulled out. The cap member 6 is made of, for example, silicon rubber.

次に、基板取外し治具を用いて、ＰＣＢサポート２から基板１を取り外す手順について説明する。図２は図１の基板取外し治具を用いてＰＣＢサポート２から基板１を取り外す手順を示す説明図である。図において、まず、筒部３１に矢尻部２２が挿入されるように基板取外し治具を基板１に近づける。これにより、矢尻部２２は、取付孔１１を通過可能となるように、径方向について収縮する。また、矢尻部２２は、押出部３２により、取付孔１１から押し出される方向に押圧される。その結果、矢尻部２２の最外周部分が取付孔１１に収容される。その後、作業者は、基板取外し治具を基板１に当接させた状態で、矢尻部２２を取付孔１１から引き抜くように基板１をＰＣＢサポート２から取り外す。   Next, a procedure for removing the substrate 1 from the PCB support 2 using the substrate removal jig will be described. FIG. 2 is an explanatory view showing a procedure for removing the substrate 1 from the PCB support 2 using the substrate removal jig of FIG. In the figure, first, the substrate removal jig is brought closer to the substrate 1 so that the arrowhead portion 22 is inserted into the cylindrical portion 31. Thereby, the arrowhead part 22 shrink | contracts about a radial direction so that the attachment hole 11 can be passed. Moreover, the arrowhead part 22 is pressed in the direction pushed out from the attachment hole 11 by the pushing part 32. As a result, the outermost peripheral part of the arrowhead part 22 is accommodated in the mounting hole 11. Thereafter, the operator removes the substrate 1 from the PCB support 2 so that the arrowhead portion 22 is pulled out from the mounting hole 11 in a state where the substrate removal jig is in contact with the substrate 1.

その後、矢尻部２２が引き抜かれた取付孔１１にキャップ部材６を挿入する。これにより、取付孔１１に矢尻部２２が再び挿入されることが防止される。全ての取付孔１１から矢尻部２２が引き抜かれると、基板１が土台７から切り離される。最後に、取付孔１１からキャップ部材６を引き抜き、基板取外し治具を用いてＰＣＢサポート２から基板１を取り外す手順が終了する。   Thereafter, the cap member 6 is inserted into the mounting hole 11 from which the arrowhead 22 has been pulled out. This prevents the arrowhead 22 from being inserted again into the mounting hole 11. When the arrowhead part 22 is pulled out from all the mounting holes 11, the substrate 1 is separated from the base 7. Finally, the procedure of pulling out the cap member 6 from the attachment hole 11 and detaching the substrate 1 from the PCB support 2 using the substrate removal jig is completed.

以上説明したように、この発明の実施の形態１に係る基板取外し治具によれば、矢尻部２２が挿入される筒部３１を備え、筒部３１は、筒部３１に矢尻部２２が挿入されることにより、矢尻部２２が取付孔１１を通過可能となるように、矢尻部２２を径方向について収縮させるので、基板１の表面側から矢尻部２２を収縮させて、矢尻部２２を取付孔１１から引き抜くように基板１をＰＣＢサポート２から取り外すことができる。その結果、基板１をＰＣＢサポート２からより確実に取り外すことができる。   As described above, according to the substrate removal jig according to the first embodiment of the present invention, the cylindrical portion 31 is inserted with the arrowhead portion 22, and the cylindrical portion 31 is inserted into the cylindrical portion 31. By doing so, the arrowhead portion 22 is contracted in the radial direction so that the arrowhead portion 22 can pass through the mounting hole 11, so that the arrowhead portion 22 is attached by contracting the arrowhead portion 22 from the surface side of the substrate 1. The substrate 1 can be removed from the PCB support 2 so as to be pulled out from the hole 11. As a result, the substrate 1 can be more reliably removed from the PCB support 2.

また、この基板取外し治具は、矢尻部２２が引き抜かれた取付孔１１を塞ぐキャップ部材６を備えているので、基板１に複数の取付孔１１が形成されている場合であって、既に何れかの取付孔１１から矢尻部２２が引き抜かれた状態で、まだ矢尻部２２が引き抜かれていない他の取付孔１１がある場合に、既に矢尻部２２が引き抜かれた取付孔１１に矢尻部２２が再び挿入されることを防止することができる。これにより、基板１の取外しの作業効率を向上させることができる。   Moreover, since this board | substrate removal jig | tool is equipped with the cap member 6 which block | closes the attachment hole 11 from which the arrowhead part 22 was extracted, it is a case where several attachment holes 11 are formed in the board | substrate 1, In the state in which the arrowhead 22 is pulled out from the mounting hole 11 and there is another mounting hole 11 from which the arrowhead 22 has not yet been pulled out, the arrowhead 22 in the mounting hole 11 from which the arrowhead 22 has already been pulled out. Can be prevented from being inserted again. Thereby, the work efficiency of removal of the board | substrate 1 can be improved.

実施の形態２．
図３はこの発明の実施の形態２に係る基板取外し治具を示す側面図である。図において、基板取外し治具は、キャップ部材６を収容する収容部３３と、収容部３３に収容されたキャップ部材６を押圧する押出棒（押圧部材）３４とを備えている。 Embodiment 2. FIG.
FIG. 3 is a side view showing a substrate removal jig according to Embodiment 2 of the present invention. In the figure, the substrate removal jig includes a housing part 33 for housing the cap member 6 and a push bar (pressing member) 34 for pressing the cap member 6 housed in the housing part 33.

収容部３３は、矢尻部２２が挿入される筒部３３１と、筒部３３１の矢尻部２２が挿入される開口部とは反対側の開口部を覆うように筒部３３１に設けられ、押出棒３４を案内するガイド部３３２とを有している。筒部３３１の径方向についての寸法は、実施の形態１に記載の筒部３１と同様である。ガイド部３３２には、筒部３３１の軸方向に延びた貫通孔３３３が形成されており、この貫通孔３３３に押出棒３４が挿入されている。キャップ部材６は、径方向に収縮した状態で筒部３３１に収容されている。筒部３３１に収容されたキャップ部材６は、押出棒３４により、筒部３３１の軸方向に移動可能となっている。押出棒３４は、押出棒３４と矢尻部２２との間にキャップ部材６を挟んだ状態で、矢尻部２２が取付孔１１から引き抜かれる方向に矢尻部２２を押圧する。その他の構成は、実施の形態１と同様である。   The accommodating part 33 is provided in the cylinder part 331 so as to cover the cylinder part 331 into which the arrowhead part 22 is inserted and the opening part of the cylinder part 331 opposite to the opening part into which the arrowhead part 22 is inserted. 34 and a guide portion 332 for guiding 34. The dimension of the cylindrical part 331 in the radial direction is the same as that of the cylindrical part 31 described in the first embodiment. A through hole 333 extending in the axial direction of the cylindrical portion 331 is formed in the guide portion 332, and the push rod 34 is inserted into the through hole 333. The cap member 6 is accommodated in the cylindrical portion 331 in a state of being contracted in the radial direction. The cap member 6 accommodated in the cylindrical portion 331 is movable in the axial direction of the cylindrical portion 331 by the push rod 34. The pushing bar 34 presses the arrowhead 22 in the direction in which the arrowhead 22 is pulled out from the mounting hole 11 with the cap member 6 being sandwiched between the pushing bar 34 and the arrowhead 22. Other configurations are the same as those in the first embodiment.

次に、基板取外し治具を用いて、ＰＣＢサポート２から基板１を取り外す手順について説明する。まず、筒部３３１に矢尻部２２が挿入されるように基板取外し治具を基板１に取り付ける。これにより、矢尻部２２は、取付孔１１を通過可能となるように、径方向について収縮する。   Next, a procedure for removing the substrate 1 from the PCB support 2 using the substrate removal jig will be described. First, a substrate removal jig is attached to the substrate 1 so that the arrowhead portion 22 is inserted into the cylindrical portion 331. Thereby, the arrowhead part 22 shrink | contracts about a radial direction so that the attachment hole 11 can be passed.

その後、押出棒３４を基板１に向かって押圧する。これにより、押出棒３４は、矢尻部２２との間にキャップ部材６を挟んだ状態で矢尻部２２を押圧する。その結果、キャップ部材６は、押出棒３４により矢尻部２２を取付孔１１から押し出しながら取付孔１１を塞ぐ。全ての取付孔１１から矢尻部２２が引き抜かれると、基板１が土台７から切り離される。最後に、取付孔１１からキャップ部材６を引き抜き、基板取外し治具を用いて、ＰＣＢサポート２から基板１を取り外す手順が終了する。   Thereafter, the push rod 34 is pressed toward the substrate 1. Thereby, the push rod 34 presses the arrowhead part 22 in a state where the cap member 6 is sandwiched between the pusher bar 34 and the arrowhead part 22. As a result, the cap member 6 closes the attachment hole 11 while pushing the arrowhead 22 from the attachment hole 11 by the push rod 34. When the arrowhead part 22 is pulled out from all the mounting holes 11, the substrate 1 is separated from the base 7. Finally, the procedure of pulling out the cap member 6 from the attachment hole 11 and removing the substrate 1 from the PCB support 2 using the substrate removal jig is completed.

以上説明したように、この発明の実施の形態２に係る基板取外し治具によれば、矢尻部２２が取り出された取付孔１１を塞ぐキャップ部材６と、矢尻部２２との間にキャップ部材６を挟んだ状態で、矢尻部２２が取付孔１１から引き抜かれる方向に矢尻部２２を押圧する押出棒３４を備え、キャップ部材６は、押出棒３４により矢尻部２２を取付孔１１から押し出しながら取付孔１１を塞ぐので、取付孔１１から矢尻部２２を引き抜くと同時に取付孔１１にキャップ部材６を取り付けることができる。その結果、ＰＣＢサポート２から基板１を取り外す効率を向上させることができる。   As described above, according to the substrate removing jig according to the second embodiment of the present invention, the cap member 6 is interposed between the cap member 6 that closes the mounting hole 11 from which the arrowhead portion 22 is taken out and the arrowhead portion 22. The cap member 6 is mounted while pushing out the arrowhead 22 from the mounting hole 11 by the pusher bar 34. The pusher 34 pushes the arrowhead 22 in the direction in which the arrowhead 22 is pulled out of the mounting hole 11. Since the hole 11 is closed, the cap member 6 can be attached to the attachment hole 11 at the same time that the arrowhead portion 22 is pulled out from the attachment hole 11. As a result, the efficiency of removing the substrate 1 from the PCB support 2 can be improved.

なお、上記実施の形態２では、１個のキャップ部材６が筒部３３１に収容される構成について説明したが、複数のキャップ部材６が筒部３３１に収容される構成であってよい。   In the second embodiment, the configuration in which one cap member 6 is accommodated in the cylindrical portion 331 has been described, but a configuration in which a plurality of cap members 6 are accommodated in the cylindrical portion 331 may be employed.
