以下、図を参照して本発明を実施するための最良の形態を詳細に説明する。
（実施形態１）
図１は本発明を適用したフレキシブルプリント基板の実施形態１の構成を示すもので、１はフレキシブルプリント基板、２は孔部、３は変形可能部、４は入力端、５は出力端、６は配線部である。なお、配線部をエッチングなどで成形するフレキシブルプリント基板以外に、導電線を配線したり、導電パターンを貼り付けたりするフレキシブル配線基板であってもよい。 Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment 1)
FIG. 1 shows the configuration of a first embodiment of a flexible printed circuit board to which the present invention is applied. 1 is a flexible printed circuit board, 2 is a hole, 3 is a deformable part, 4 is an input end, 5 is an output end, 6 Is a wiring part. In addition to the flexible printed board in which the wiring portion is formed by etching or the like, a flexible wiring board in which conductive wires are wired or a conductive pattern is attached may be used.

フレキシブルプリント基板１は、そのフレキシブルフィルムによるベース部に、図示例において、ベース部を貫通して菱形形状の孔部２を長手方向に２個並べて形成し、その孔部２の周囲を囲むベース部自体で、引張力により伸張方向に湾曲して変形可能な変形可能部３を形成したものである。
そして、入力端４から変形可能部３を経て出力端５に向かい配線部６が形成されており、図示例では、入力端４に４本の配線部６が形成され、その入力端４から左右２本ずつに分岐して変形可能部３に配線部６が形成されて、再び出力端５で４本の配線部６が収束するよう形成されている。なお、入力端４、及び出力端５は配線部６が露出しているが、他の部分はベース部内に形成されるか、あるいは、非導電性の被膜で覆われている。 In the illustrated example, the flexible printed circuit board 1 is formed by arranging two rhombus-shaped hole portions 2 in the longitudinal direction so as to penetrate the base portion in the illustrated example, and surround the periphery of the hole portion 2. By itself, the deformable portion 3 is formed which can be deformed by being bent in the extension direction by a tensile force.
A wiring portion 6 is formed from the input end 4 to the output end 5 through the deformable portion 3. In the illustrated example, four wiring portions 6 are formed at the input end 4, and left and right from the input end 4. The wiring part 6 is branched into two pieces, the wiring part 6 is formed in the deformable part 3, and the four wiring parts 6 are converged again at the output end 5. In addition, although the wiring part 6 is exposed at the input end 4 and the output end 5, the other part is formed in the base part or covered with a non-conductive film.

以上において、孔部２は、縦横比を異ならせた形状、すなわち、横長の菱形形状とされていて、具体的には、フレキシブルプリント基板１の入力端４から出力端５へ向かう伸び方向の対角線（長さＬ１）より、伸び方向以外の対角線の方が長くて、その孔部２の辺同士が互いに対向して配置されている。   In the above, the hole 2 has a shape with a different aspect ratio, that is, a horizontally long rhombus, and specifically, a diagonal line extending in the direction from the input end 4 to the output end 5 of the flexible printed circuit board 1. The diagonal line other than the extending direction is longer than (length L1), and the sides of the hole 2 are arranged to face each other.

図２は以上のフレキシブルプリント基板１を伸ばした状態を示したもので、その長手方向に引っ張ると、図示のように、孔部２の周囲を囲む変形可能部３が湾曲変形して伸び、その孔部２の伸び方向の対角線の長さがＬ２と長くなる。
このように、本来は伸縮しない材料のフレキシブルプリント基板１でありながら、孔部２の周囲を囲む変形可能部３が湾曲変形して伸びるものとなる。 FIG. 2 shows a state in which the flexible printed circuit board 1 is stretched. When the flexible printed circuit board 1 is stretched in the longitudinal direction, the deformable portion 3 surrounding the hole 2 is curved and deformed as shown in the figure. The length of the diagonal line in the extending direction of the hole 2 is increased to L2.
As described above, the deformable portion 3 surrounding the periphery of the hole portion 2 is curved and deformed while the flexible printed circuit board 1 is originally made of a material that does not expand and contract.

なお、引張力を解除すれば、フレキシブルプリント基板１は変形可能部３で縮んで図１に示した元の状態に復帰する。   When the tensile force is released, the flexible printed circuit board 1 is contracted by the deformable portion 3 and returned to the original state shown in FIG.

また、図示例において、孔部２の角部は、その周囲の変形可能部３の伸張時に裂けるのを防止するためにＲ形状となっている。   In the illustrated example, the corner of the hole 2 has an R shape to prevent tearing when the deformable portion 3 around the hole 2 is stretched.

以上、実施形態のフレキシブルプリント基板１によれば、２個の孔部２を各々囲む変形可能部３のそれぞれの湾曲変形により、実装厚みを薄くしながら、伸縮できる。   As described above, according to the flexible printed circuit board 1 of the embodiment, each of the deformable portions 3 surrounding each of the two hole portions 2 can be expanded and contracted while reducing the mounting thickness.

（実施形態２）
図３は実施形態２のフレキシブルプリント基板の構成を示すもので、前述した実施形態１と同様に、菱形形状の孔部２を１個のみとし、その孔部２を囲む１個の変形可能部３を有するフレキシブルプリント基板１としたものである。
このように、孔部２は１個のみであっても、その周囲の変形可能部３により伸縮可能である。 (Embodiment 2)
FIG. 3 shows the configuration of the flexible printed circuit board according to the second embodiment. As in the first embodiment described above, only one rhombus-shaped hole 2 is provided and one deformable portion surrounding the hole 2 is formed. 3 is a flexible printed circuit board 1.
Thus, even if there is only one hole 2, it can be expanded and contracted by the deformable portion 3 around it.

なお、孔部２が大きくて、変形可能部３の幅が小さい方が、より伸縮しやすいものとなる。   In addition, the one where the hole part 2 is large and the width | variety of the deformable part 3 is small becomes easier to expand and contract.

（実施形態３）
図４は実施形態３のフレキシブルプリント基板の構成を示すもので、前述した実施形態１と同様に、２個の菱形形状の孔部２を囲む変形可能部３の間に帯状部７を設けたものである。

図５は以上のフレキシブルプリント基板１を伸ばした状態を示したもので、その長手方向に引っ張ると、図示のように、２個の孔部２の周囲の変形可能部３が、帯状部７により分断されて、各々独立に湾曲変形して伸びる。   FIG. 5 shows a state in which the above flexible printed circuit board 1 is extended. When the flexible printed circuit board 1 is stretched in the longitudinal direction, the deformable portion 3 around the two holes 2 is formed by the belt-like portion 7 as shown in the figure. It is divided and each of them is bent and deformed independently.

（実施形態４）

FIG. 6 shows the configuration of the flexible printed board according to the fourth embodiment. 11 is a flexible printed board, 12 is a hole, 13 is a deformable part, 14 is an input end, 15 is an output end, and 16 is a wiring part. .

フレキシブルプリント基板１１は、そのフレキシブルフィルムによるベース部に、図示例において、ベース部を貫通して略長円形状の孔部１２を長手方向に２個並べて形成し、その孔部１２の周囲を囲むベース部自体で、引張力により伸張方向に湾曲して変形可能な変形可能部１３を形成したものである。
そして、入力端１４から変形可能部１３を経て出力端１５に向かい配線部１６が形成されており、図示例では、入力端１４に４本の配線部１６が形成され、その入力端１４から左右２本ずつに分岐して変形可能部１３に配線部１６が形成されて、再び出力端１５で４本の配線部１６が収束するよう形成されている。 In the illustrated example, the flexible printed circuit board 11 is formed by arranging two substantially oval hole portions 12 in the longitudinal direction so as to pass through the base portion and surround the periphery of the hole portion 12. The base part itself forms a deformable part 13 that can be deformed by bending in the extension direction by a tensile force.
A wiring portion 16 is formed from the input end 14 to the output end 15 through the deformable portion 13. In the illustrated example, four wiring portions 16 are formed at the input end 14, The wiring part 16 is formed in the deformable part 13 by branching two by two, and the four wiring parts 16 are converged again at the output end 15.

以上において、孔部１２は、縦横比を異ならせた形状、すなわち、横長の略長円形状とされていて、具体的には、フレキシブルプリント基板１１の入力端１４から出力端１５へ向かう伸び方向の幅より、伸び方向以外の幅の方が広くされている。
このように、横長の略長円形状の孔部１２によっても、その周囲の変形可能部１３により伸縮可能である。 In the above, the hole portion 12 has a shape with a different aspect ratio, that is, a horizontally long substantially oval shape. Specifically, the hole portion 12 extends in the direction from the input end 14 to the output end 15 of the flexible printed circuit board 11. The width other than the direction of elongation is wider than the width of.
As described above, even the horizontally long and substantially oval hole 12 can be expanded and contracted by the deformable portion 13 around the hole 12.

（実施形態５）

フレキシブルプリント基板２１は、そのフレキシブルフィルムによるベース部に、前述した実施形態１と同様に、ベース部を貫通して菱形形状の孔部２２を長手方向に２個並べて形成するとともに、その間にも同じく菱形形状の孔部２２を幅方向に２個並べて形成し、これにより千鳥状配置による４個の孔部２２の周囲を囲むベース部自体で、引張力により伸張方向に湾曲して変形可能な変形可能部２３を形成したものである。   The flexible printed circuit board 21 is formed by arranging two rhombus-shaped hole portions 22 in the longitudinal direction so as to penetrate the base portion in the base portion of the flexible film, as in the first embodiment described above. Two rhombus-shaped hole portions 22 are formed side by side in the width direction, so that the base portion itself surrounding the four hole portions 22 in a staggered arrangement can be deformed by bending in a stretching direction by a tensile force. The possible part 23 is formed.

そして、入力端２４から変形可能部２３を経て出力端２５に向かい配線部２６が形成されており、図示例では、入力端２４に４本の配線部２６が形成され、その入力端２４から左右２本ずつに分岐して変形可能部２３の外側に沿って配線部２６が形成されて、再び出力端２５で４本の配線部２６が収束するよう形成されている。   A wiring portion 26 is formed from the input end 24 through the deformable portion 23 toward the output end 25. In the illustrated example, four wiring portions 26 are formed at the input end 24. The wiring part 26 is formed so as to branch into two pieces along the outer side of the deformable part 23, and the four wiring parts 26 converge again at the output end 25.

このように、千鳥状配置による４個の孔部２２を囲む大きな菱形形状の変形可能部２３としても伸縮可能である。   Thus, the large rhombus-shaped deformable portion 23 surrounding the four hole portions 22 in a staggered arrangement can be expanded and contracted.
