Description

本発明は、電子機器等の内部部品同士を電気的に絶縁するためのフィルムの固定方法に関するものである。 The present invention relates to a film fixing method for electrically insulating internal components such as electronic devices.

電子機器等の内部部品同士を電気的に絶縁する対象として、プリント板の実装部品と筐体板金間の例がある。電子機器等を小型化するためには、プリント板の実装部品と筐体板金間はできるだけ小さくしたいが、近づけすぎると短絡の恐れがあるため絶縁フィルムを挟む構造がとられている。図４に示す従来例では、電子部品１等を搭載したプリント板２と筐体板金３の間に絶縁フィルム４を挟む構造において、絶縁フィルム４を固定するために両面テープ５を用いて筐体板金３に貼り付けていた。なお、部品同士を電気的に絶縁することは例えば特許文献１によっても知られている。この文献のものは、ケース内側の金具が露出している部分に絶縁フィルムを貼り付けた例についても説明している。
実用新案登録第２５１６１８１号 As an object for electrically insulating internal components such as electronic devices, there is an example between a printed board mounting component and a housing sheet metal. In order to reduce the size of an electronic device or the like, it is desired to make the space between the printed board mounting component and the housing sheet metal as small as possible. In the conventional example shown in FIG. 4, in a structure in which an insulating film 4 is sandwiched between a printed board 2 on which an electronic component 1 or the like is mounted and a casing sheet metal 3, a double-sided tape 5 is used to fix the insulating film 4. It was pasted on the sheet metal 3. In addition, electrically insulating parts is also known from Patent Document 1, for example. This document also describes an example in which an insulating film is attached to a portion where the metal fitting inside the case is exposed.
Utility model registration No. 2516181

両面テープを用いて絶縁フィルムを固定する方法はコストが高く、貼り直しもできない。また、資源の有効活用で筐体板金を再利用するためには絶縁フィルムを剥がさなければならないが、両面テープで固定しているので剥がしにくいという問題があった。本発明の目的は、絶縁フィルムの固定を容易にする方法を提供することにある。   The method of fixing an insulating film using a double-sided tape is expensive and cannot be re-applied. In addition, in order to reuse the housing sheet metal for effective utilization of resources, the insulating film must be peeled off, but there is a problem that it is difficult to peel off because it is fixed with double-sided tape. An object of the present invention is to provide a method for facilitating fixing of an insulating film.

本発明の第１は、プリント板と筐体板金との間に絶縁フィルムを挟んで電気的に絶縁するものにおいて、
前記プリント板を固定するために筐体板金に植設されたかしめボスの位置に合わせて絶縁フィルムに穴を穿設し、且つこの穴を起点に放射状の切れ目を設けてかしめボスに押し込むことで筐体板金に絶縁フィルムを取り付けることを特徴とした方法である。 The first of the present invention is to electrically insulate by sandwiching an insulating film between the printed board and the housing sheet metal,
In order to fix the printed board, a hole is made in the insulating film in accordance with the position of the caulking boss implanted in the housing sheet metal, and a radial cut is provided starting from the hole, and the caulking boss is pushed into the hole. It is a method characterized by attaching an insulating film to a housing sheet metal.

本発明の第２は、プリント板と筐体板金との間に絶縁フィルムを挟んで電気的に絶縁するものにおいて、
前記筐体板金に突起部を設け、この突起部位置に対応した絶縁フィルムの当該位置に断面形状の穴を設け、この穴を前記筐体板金の突起部が貫通して絶縁フィルムを取り付けることを特徴とした方法である。 The second of the present invention is to electrically insulate by sandwiching an insulating film between the printed board and the housing sheet metal,
Providing a projection on the housing sheet metal, providing a hole with a cross-sectional shape at the position of the insulating film corresponding to the position of the projection, and attaching the insulating film through the projection of the housing sheet metal. It is a featured method.

本発明の第３は、プリント板プリント板と筐体板金との間に絶縁フィルムを挟んで電気的に絶縁するものにおいて、
前記筐体板金に突起部を形成し、この突起部の頂点位置に穴を設け、前記突起部位置に対応した絶縁フィルムの当該位置に舌状部を有する切り込みを形成し、この舌状部を前記突起部に設けた穴に挿し込んで絶縁フィルムを取り付けることを特徴とした方法である。 The third of the present invention is to electrically insulate by sandwiching an insulating film between the printed board printed board and the housing sheet metal,
A protrusion is formed on the housing sheet metal, a hole is formed at the apex position of the protrusion, and a notch having a tongue-like portion is formed at the position of the insulating film corresponding to the protrusion position. In this method, the insulating film is attached by being inserted into a hole provided in the protrusion.

本発明の第４は、前記突起部の穴に挿し込まれる絶縁フィルムの舌状部の導出方向は左右対称とされることを特徴とした方法である。   A fourth aspect of the present invention is a method characterized in that the direction in which the tongue-shaped portion of the insulating film inserted into the hole of the protruding portion is symmetric is left-right.

以上のとおり、本発明によれば、両面テープを用いて絶縁フィルムを固定する方法よりもコストが安価で、製作が容易である。また、筐体板金から絶縁フィルムを容易に分離できるので資源の有効活用が可能となる。   As described above, according to the present invention, the cost is lower than the method of fixing the insulating film using the double-sided tape, and the manufacture is easy. Further, since the insulating film can be easily separated from the housing sheet metal, resources can be effectively used.

本発明の実施形態を以下に詳述する。
図１は、本発明の第１の実施形態を示す構成図である。電子部品１等を搭載したプリント板２と筐体板金３との間を電気的に絶縁するために絶縁フィルム４を挟んだ構成において、プリント板２を固定するために筐体板金３に植設されたかしめボス６の位置に合わせて絶縁フィルム４に穿設し、且つこの穴７を起点に放射状の切れ目８を設けてかしめボス６に押し込むことで筐体板金３に絶縁フィルム４を取り付けて固定できるようにしたものである。絶縁フィルム４に穿設する穴７は絶縁フィルム４の外形抜きと同時に形成することができる。穴７を起点に放射状の切れ目８を設けることでかしめボス６に容易に押し込むことができ、且つ容易には抜けない効果がある。 Embodiments of the present invention are described in detail below.
FIG. 1 is a configuration diagram showing a first embodiment of the present invention. In a configuration in which an insulating film 4 is sandwiched between the printed board 2 on which the electronic component 1 or the like is mounted and the casing sheet metal 3 to electrically insulate, the casing sheet metal 3 is implanted to fix the printed board 2. The insulating film 4 is drilled in accordance with the position of the caulking boss 6, and a radial cut 8 is provided starting from the hole 7, and the insulating film 4 is attached to the housing sheet metal 3 by pushing into the caulking boss 6. It can be fixed. The hole 7 formed in the insulating film 4 can be formed simultaneously with the outer shape removal of the insulating film 4.
