Description
【考案の詳細な説明】 ［産業上の利用分野］ 本考案は、自動車電話等のハンドセットのシールド構造
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a shield structure for a handset such as a car phone.
特に、電気的特性を確実に満たすことのできるシールド
構造に関するものである。In particular, the present invention relates to a shield structure that can surely satisfy electrical characteristics.
［従来の技術］ 従来、この種ハンドセットのシールド構造は、第３図に

充分に満たすことができないという問題があった。[Problems to be Solved] In the above-described conventional shield structure, aluminum is vapor-deposited or conductive coating is applied only to the inside of the cover 1 and the case 2, so that the shield between the cover 1 and the case 2 between the upper and lower sides. However, there is a problem that the electrical characteristics cannot be sufficiently satisfied and the electrical characteristics cannot be sufficiently satisfied.

The contact is made.
［実施例］ 以下、本考案の一実施例について図面を参照して説明す
る。[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.
第１図は本考案に係るハンドセットのシールド構造の一
実施例を示す斜視図、第２図は同じく部分拡大断面図で
ある。FIG. 1 is a perspective view showing an embodiment of a shield structure for a handset according to the present invention, and FIG. 2 is a partially enlarged sectional view of the same.
本実施例のシールド構造は、ハンドセットのカバー11お
よびケース12の内側に、予めアルミ蒸着または導電塗装
を施しておく。In the shield structure of this embodiment, the inside of the cover 11 and the case 12 of the handset is previously vapor-deposited with aluminum or conductively coated.
また、ケース12には凸状のリブ12aを設けておく。Further, the case 12 is provided with a convex rib 12a.
一方、バネ状の材料からなる断面コ字形のシールド板13
を用意する。本実施例では、このシールド板13の一端縁
部に引っ掛け部13aを形成してある。On the other hand, a shield plate 13 made of a spring-like material and having a U-shaped cross section
To prepare. In this embodiment, a hooking portion 13a is formed on one edge of the shield plate 13.
そして、ケース12のリブ12aにシールド板13をはめこ
み、カバー11をケース12にはめあわせる。Then, the shield plate 13 is fitted into the rib 12a of the case 12, and the cover 11 is fitted to the case 12.
これによって、シールド板13が第２図に示すようにたわ
んで、カバー11と接触することとなる。As a result, the shield plate 13 bends as shown in FIG. 2 and comes into contact with the cover 11.
以上のようなシールド構造は、ケース12のリブ12aにシ
ールド板13をはめこんであるので、アルミ蒸着または導
電塗装を施しただけでは不安定であった電気的特性を確
実に満たすことができる。In the shield structure as described above, since the shield plate 13 is fitted in the rib 12a of the case 12, it is possible to surely satisfy the electrical characteristics that were unstable only by applying aluminum vapor deposition or conductive coating.
また、シールド板13の一端縁部には、引っ掛け部13aを
形成してあるので、ハンドセットを開けた場合でも、両
面接着テープや接着剤を使用していないにもかかわら
ず、シールド板13が外れないという効果もある。Further, since the hooked portion 13a is formed on one end edge of the shield plate 13, the shield plate 13 is removed even when the handset is opened, even though the double-sided adhesive tape or adhesive is not used. There is also the effect that there is no.
なお、凸状のリブをカバー側に設けても、上下が逆にな
るだけであるので同様の効果を有することはいうまでも
ない。Needless to say, even if the convex ribs are provided on the cover side, the same effect is obtained because only the top and bottom are turned upside down.
［考案の効果］ 以上説明したように本考案は、シールド板を用いること
により、カバーとケースとの間における上下間のシール
ドを確実に取ることができ、電気的特性を充分に満たす
ことができる。[Advantages of the Invention] As described above, the present invention can reliably secure the upper and lower shields between the cover and the case by using the shield plate, and can sufficiently satisfy the electrical characteristics. .
