図2はFPC5の上面図である。 Figure 2 is a top view of the FPC 5. FPC5の表面51上には電子部品55が表面実装され、電子部品55が表面実装される部品実装領域4に対応する裏面52には補強板53が取り付けられている。 On the surface 51 of the FPC5 are electronic component 55 is surface mounted, the reinforcing plate 53 is attached to the rear surface 52 corresponding to the component mounting area 4 of the electronic component 55 is surface mounted. 部品実装領域4の幅は、凸部3の上面31の幅と同一以下、若干短めとしている。 Width of the component mounting region 4, the width of the upper surface 31 of the convex portion 3 and the same or less, and a slightly shorter.

FPC5が固定部材1と押え具2に挟まれる時に、FPC5は一点鎖線Xに沿って折り曲げられることになるので、一点鎖線X上には補強板53を設けていない。 When FPC 5 is sandwiched between the fixing member 1 and the retainer 2, FPC 5 is it means to be bent along the dashed line X, not provided a reinforcing plate 53 on the one-dot chain line X. 尚、部品実装領域4の裏面ではないが、FPC5の裏面52には、一点鎖線Xを境界に分割された補強板54を、固定部材1と押え具2に挟まれる部分に設けることとしてもよい。 Although not the rear surface of the component mounting area 4, the rear surface 52 of FPC5 is a reinforcing plate 54 divides the one-dot chain line X in the boundary, may be provided in a portion sandwiched between the fixed member 1 and the retainer 2 .

このように補強板53を設けることにより、FPC5の折り曲げが、補強板53の外側で円滑に行われ、FPC5の折り曲げ時にも、補強板53が設けられた部分は撓まず、部品実装領域4に応力が掛かりにくい構造とすることが出来、部品や回路の破損を防止することが出来る。 By providing the reinforcing plate 53, bending the FPC 5 is smoothly performed outside of the reinforcing plate 53, even when bending the FPC 5, the portion where the reinforcing plate 53 is provided is not bent, the component mounting area 4 can be a stress-consuming hard structure, it is possible to prevent damage to the components and circuits. 補強板53、54には、従来から用いられているポリイミド等の合成樹脂製の板を用いればよい。 The reinforcing plate 53 and 54, may be used synthetic resin plate such as polyimide which has been used conventionally.

このように、固定のためにFPC5に切り欠部、フック等の特別な部材、部位を設ける必要がないので、基板レイアウトに制約が生じることなく、又、製造コストを廉価とすることが出来る。 Thus, the cut-out portions cut in FPC5 for fixing, special member of the hook or the like, there is no need to provide a site, without restrictions on the board layout is generated, also, it is possible to manufacturing cost and inexpensive.

次にFPC5を押え具2を用いて固定部材1に固定する手順を、図3及び4を参照して説明する。 Then a procedure for fixing the fixing member 1 with pressers 2 FPC 5, will be described with reference to FIGS. 3 and 4. 先ず、固定部材1の上に、凸部3の上面31上に部品実装領域4を上方に向けて位置させ、FPC5を載置する。 First, on the fixed member 1, a component mounting area 4 is positioned upward on the upper surface 31 of the convex portion 3, placing the FPC 5. 次に、FPC5を固定部材1の形状に合わせて折り曲げる。 Next, bent according to the shape of the fixing member 1 and FPC 5. この時、FPC5は凸部3を跨いで設置される。 In this case, FPC 5 is placed across the convex portion 3. この際、部品実装領域4の裏面に補強板53が設けられ、場合によっては補強板54が設けられているので、補強板53、54の外側に沿って、一点鎖線Xの部分で容易に折り曲げることが出来る。 In this case, the reinforcing plate 53 is provided on the back surface of the component mounting area 4, since the reinforcing plate 54 is provided in some cases, along the outside of the reinforcing plate 53 and 54, easily folded at the portion of the one-dot chain line X it can be. 最後に、押え具2を部品実装領域4が開口部20をくぐるように、固定部材1に嵌め込む。 Finally, the holding member 2 component mounting region 4 as it passes through the opening 20, fitted to the fixed member 1.

このように、一個のフレキシブルプリント基板の固定作業において、一の固定部材1へ一の押え具2を嵌合する僅かに1回の作業で、固定が完了するので、固定部材1へのFPC5の固定作業を容易とし、固定作業の作業効率を高めることが可能となっている。 Thus, in operation of fixing one of the flexible printed circuit board, with slightly one operation of fitting the one retainer 2 to one fixing member 1, since the fixing is completed, FPC 5 of the fixed member 1 the fixing operation is facilitated, it is possible to improve the work efficiency of fixing operation.

図4は、押え具2を用いてFPC5を固定部材1に固定した状態の断面図である。 Figure 4 is a cross-sectional view of a fixed state in the fixing member 1 to FPC5 with pressers 2. FPC5の裏面52に設けた補強板53、54は分割されているので、固定部材1に沿った折り曲げが可能となっている。 Since the reinforcing plate 53, 54 provided on the back surface 52 of FPC5 is divided, and can have folded along the fixed member 1. この固定の際にFPC5が撓むのは、折り目の部分8だけなので、実装された部品55には応力が加わらないようになっているので、フレキシブルプリント基板上の部品や回路の破損を防止することが出来る。 The FPC5 that flex during this fixed, since only the portion 8 of the fold, since the implemented components 55 so as not applied stress, is possible to prevent damage to the components and circuitry on the flexible printed circuit board can. 又、固定部材へ押え具を嵌合して固定するので、フレキシブルプリント基板の固定が解除される恐れがなく、強固な固定とすることが可能となっている。 In addition, since fitted to secure the retainer to the fixed member, there is no possibility that the flexible printed circuit board fixed is released, it is possible to firmly fix.

図3及び4では、電子部品55が表面実装される部品実装領域4を上に向けて、水平に置かれた状態でFPC5が固定されているが、部品実装領域4を下に向けて、水平に置かれた状態や、横向きに置かれた状態でも固定することが可能である。 3 and 4, toward the component mounting area 4 of the electronic component 55 is surface mounted on, although FPC5 in a state of being placed horizontally are fixed, toward the component mounting area 4 down, horizontal state and placed in, it is also possible to fix in a state placed sideways.

尚、上記説明及び参照した図面では、FPC5は長方形のものとして説明しているが、図5に示すように、図2で示したFPC5から余分な部分を切欠いて、切り欠部59を設けたFPC5を用いることも可能である。 In the above description and with reference to the accompanying drawings, FPC 5 is has been described as being rectangular, as shown in FIG. 5, cut away the excess portion from the FPC 5 shown in FIG. 2, provided with a notch portion 59 it is also possible to use FPC 5. 本発明による固定では、固定部材1と押え具2の間にFPC5が挟まれていればよいので、固定部材1と押え具2の間に位置するFPC5の一部を切り欠いても、逆にいえば、固定部材1と押え具2の間の一部にしかFPC5が存在しなくてもよく、一部を切り欠いたFPC5でも固定部材1への固定が可能である。 In the fixed according to the invention, since it is sufficient that is sandwiched FPC5 between the fixed member 1 and the retainer 2, also partially cut away FPC5 located between the fixed member 1 and the retainer 2, conversely speaking may not exist FPC5 only some between the fixed member 1 and the retainer 2, it is possible to fixation to the fixing member 1 even FPC5 a portion has been cut away. このような形状は、1枚のFPCから多くの基板を切り出す際に有効であり、製造コストの低減を図ることが出来る。 This shape is effective when cutting a number of substrates from a single FPC, it is possible to reduce the manufacturing cost.
