よび４を押し当て折シ曲げて分割していた。2. Description of the Related Art Conventionally, in this type of printed wiring board, as shown in FIG. As shown in FIG. 3, the ends 6 and 7 of the board 6 are sandwiched between a jig 9 having a striped part 8 slightly wider than the thickness of the printed wiring board 5, bent and divided into parts. As shown in FIG. 4, the dividing grooves 2 and 4 were pressed against the ridge line 11 of a jig 1Q having a substantially inverted T-shaped cross section and bent to divide the jig.
発明が解決しようとする課題
しかしながら、このような従来のプリント配線板におい
ては、前記端部６または７を分割しようとすると、前記
プリント配線板６の中央部に曲げ応力が集中するので、
第６図に示すように分割溝２が先に折れてしまうという
課題があった。Problems to be Solved by the Invention However, in such a conventional printed wiring board, when it is attempted to divide the end portions 6 or 7, bending stress is concentrated at the center of the printed wiring board 6.
As shown in FIG. 6, there was a problem in that the dividing groove 2 broke first.
本発明は上記課題を解決するもので、分割作業性の良い
プリント配線板を提供することを目的とするものである
。The present invention has been made to solve the above problems, and an object of the present invention is to provide a printed wiring board with good dividing workability.
課題を解決するだめの手段
この課題を解決するために、本発明のプリント配線板は
、分割溝に沿って長穴または切り欠きを配し、分割順序
に応じてこの長大または切り欠きの長さまたは長穴の個
数を調整するよう構成したものである。Means for Solving the Problem In order to solve this problem, the printed wiring board of the present invention has an elongated hole or notch arranged along the dividing groove, and the length of the elongated hole or notch is adjusted according to the dividing order. Alternatively, the number of elongated holes can be adjusted.
作 用
本発明は、上記の構成により、先に分割する部分の強度
を後で分割する部分の強度よりも弱くすることができる
ので、分割するｌ＋［［序に応じて強度を調整できる。Effects According to the present invention, with the above configuration, the strength of the portion to be divided first can be made weaker than the strength of the portion to be divided later, so that the strength can be adjusted depending on the order of division.
これにより、分割作業性がよくなるものである。This improves the efficiency of dividing work.
実施例
本発明の一実施例を添付図面にしたがって説明する。第
１図は本実施例のプリント配線板を示すもので１分割溝
３上に配した長穴２１，２２，２εおよび切り欠き２４
．２５を長めにしである。また、分割溝１上には長穴２
７〜３ｏを配しである。これにより１分割Ｒ３，１は分
割Ｓ２よりも弱くなっているので、端部６，７を容易に
割シ取ることができ１分割溝３または１を割ろうとした
時に分割溝２が先に割れてしまうということがない。Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows the printed wiring board of this embodiment, in which elongated holes 21, 22, 2ε and notches 24 are arranged on the one-dividing groove 3.
．． 25 is longer. In addition, there is a long hole 2 on the dividing groove 1.
The arrangement is 7-3o. As a result, the 1st division R3,1 is weaker than the division S2, so the ends 6,7 can be easily split, and when you try to break the 1st division groove 3 or 1, the dividing groove 2 will break first. There is no such thing as a problem.
なお、上記実施例では分割溝３では長穴及び切り欠きを
長めとし、分割溝１では多めの長穴を配したが、これら
は自由に組み合わせて使用することも可能である。In the above embodiment, the elongated holes and notches are longer in the dividing groove 3, and a larger number of elongated holes are provided in the dividing groove 1, but these may be used in any combination.
また、分割溝４上にも適宜長穴または切り欠きを設けて
も良い。Further, an elongated hole or a notch may be provided on the dividing groove 4 as appropriate.
発明の効果
以上のように本発明によれば、分割溝の上に設けた長穴
あるいは切や欠きの長さまたは長穴の個数を調整するこ
とにより、プリント配線板の分割作業性が良くなるとい
う効果が得られる。Effects of the Invention As described above, according to the present invention, the workability of dividing a printed wiring board is improved by adjusting the length of the elongated hole or notch or cutout provided above the dividing groove, or the number of elongated holes. This effect can be obtained.
