図4に従来のクリップ1を使って半導体素子4の固定を行っている一例を示す。図4において、プリント基板6に実装されている半導体素子4は概U字型に折曲加工した金属性のクリップ1によって、固定物である筐体5のクリップ装着スペース5bを使って、筐体5と一体に形成された筐体放熱壁5aに固定されている。図に示すように、筐体壁面内側にはクリップ装着スペース5bが設けられ、このクリップ装着スペース5bにクリップ1の固定物側の2脚が挿入配置される。
FIG. 4 shows an example in which the semiconductor element 4 is fixed using the conventional clip 1. In FIG. 4, a semiconductor element 4 mounted on a printed circuit board 6 has a metal clip 1 bent into a substantially U shape, and uses a clip mounting space 5b of the casing 5 which is a fixed object. 5 is fixed to a housing heat radiating wall 5 a formed integrally with the housing 5. As shown in the figure, a clip mounting space 5b is provided on the inner wall surface of the housing, and two legs on the fixed object side of the clip 1 are inserted into the clip mounting space 5b.

前記のクリップ1は,半導体素子4を固定するというその目的から,クリップ1の両脚2間の挟み強度は強く,又サイズは小さいため,クリップ1の脚2を開き,半導体素子4と筐体放熱壁5aなどの固定物とを挟む作業は困難であった。

In FIG. 3, the semiconductor element 4 mounted on the printed circuit board 6 is formed on the fixed object side of the clip 1 by using a clip mounting space 5 b of the housing 5 by a metal clip 1 bent into a substantially U shape. With a part of the leg 2b hooked to the tip of the casing heat radiating wall 5a, the leg 2 is opened as shown in FIG. The semiconductor heat radiating wall 5a formed integrally with the semiconductor element 4 is sandwiched between the clips 1, and the semiconductor element 4 is fixed.

前記の実施例はネジ回し7のような棒状の道具を使ってクリップ1の脚2を開き、半導体素子4を固定する実施例を説明したが、以下に参考例について、説明をする。
Examples of the open legs 2 of the clip 1 with a rod-shaped tool such as a screwdriver 7 has been described an embodiment for fixing the semiconductor element 4, reference example will now be described.

図5に第一の参考例を示す。クリップ1の両脚2の先端部2cそれぞれに穴3を開け、スナップリングプライヤー8の先端を穴に差し入れ、クリップ1の脚2を開くようにする。この場合は、前述の実施例のように、クリップ1を開く前にクリップ1の固定物側の脚2bの一部を筐体放熱壁5aの先端へ引っ掛けて、クリップ1を支えることはない。クリップ1の形状に合わせて、スナップリングプライヤー8の形状は、先端がストレートタイプや、先曲がりタイプ11を選定して、使用することができる。
FIG. 5 shows a first reference example . A hole 3 is formed in each of the tip portions 2c of both legs 2 of the clip 1, and the tip of the snap ring pliers 8 is inserted into the hole so that the leg 2 of the clip 1 is opened. In this case, unlike the above-described embodiment , the clip 1 is not supported by hooking a part of the leg 2b on the fixed object side of the clip 1 to the tip of the housing heat radiating wall 5a before opening the clip 1. According to the shape of the clip 1, the snap ring pliers 8 can be used by selecting the straight type or the forward bending type 11 as the tip.

図6に第二の発明によるクリップの実施例を示す。第一の発明によるクリップ1と共通する部位は同一の番号を用いている。第一の発明によるクリップ1と異なる部分について説明をする。クリップ1の半導体素子側の脚2aの先端部2cを外側へほぼ一周カールさせて,ネジ回し7などの道具を差し込むための略円筒形状部10を形成する。   FIG. 6 shows an embodiment of a clip according to the second invention. The parts common to the clip 1 according to the first invention use the same numbers. A different part from the clip 1 by 1st invention is demonstrated. The tip 2c of the leg 2a on the semiconductor element side of the clip 1 is curled almost once outward to form a substantially cylindrical portion 10 into which a tool such as a screwdriver 7 is inserted.

ネジ回しなどの道具を使って,第二の発明であるクリップ1の脚2を開く操作を説明する。第一の発明であるクリップ1の脚2を開く操作と同様に,クリップ1の固定物側の脚2bの一部を筐体放熱壁5aなどの固定物に引っ掛け,クリップ1を支えた状態で前記の略円筒形状部10にネジ回し7などの道具を指し込み,クリップ1の脚2を開く。   The operation of opening the leg 2 of the clip 1 according to the second invention using a tool such as a screwdriver will be described. Similarly to the operation of opening the leg 2 of the clip 1 according to the first invention, a part of the leg 2b on the fixed object side of the clip 1 is hooked on a fixed object such as the housing heat radiating wall 5a and the clip 1 is supported. A tool such as a screwdriver 7 is inserted into the substantially cylindrical portion 10 and the leg 2 of the clip 1 is opened.

図7に第二の参考例を示す。クリップ1の両脚2の先端部2cをそれぞれ外側へほぼ一周カールさせて、略円筒形状部10を形成する。スナップリングプライヤー8の先端を前記の略円筒形状部10に差し入れ、クリップ1の脚2を開くようにする。
FIG. 7 shows a second reference example . The tip portions 2c of the legs 2 of the clip 1 are each curled almost once outward to form a substantially cylindrical portion 10.

半導体素子固定用クリップ1と類似した目的と形状を有し,市販され一般に利用されているものに,書類などを綴じるためのクリップが有る。前記の書類用のクリップに対し専用の綴じ具は有るが,前記の綴じ具を使用せずに書類などを直接手で綴じようとする場合は,半導体素子固定用クリップ1の場合と同様に,綴じる作業は困難である。前記の書類などを綴じるクリップに対しても,本発明を応用すれば,使用する道具はねじ回しでなくとも,例えばボールペンのペン先や挟みなどの手近な文具を使用して,書類を容易に綴じることが可能である。   A clip for binding a document or the like is one that has a similar purpose and shape as the semiconductor element fixing clip 1 and is commercially available. Although there is a binding tool dedicated to the document clip, when the document is directly bound by hand without using the binding tool, as in the case of the semiconductor element fixing clip 1, Stitching is difficult. Even if the present invention is applied to the clip for binding the document etc., it is easy to use the stationery such as a pen of a ballpoint pen or a pinch, even if the tool to be used is not a screwdriver. It is possible to bind.
