Description
【０００１】[0001]
本考案は電子機器用ケースの構造に関し、特にケース内の基板に装着した部品 の調整、及び取外しを容易としたケースの構造に関するものである。 The present invention relates to a structure of an electronic device case, and more particularly to a structure of a case that facilitates adjustment and removal of components mounted on a board in the case.
【０００２】[0002]
従来の電子機器用ケース内に装着した部品をケース開口を介して調整及び部品 の取外しをする構造の例として、図７〜図１０に示すものがある。 図７はケース上面を全て開口とした構造の外観斜視図であり、図７によりその 構成を説明すると、符号１は１枚の金属材を打抜いて折曲げて形成したケースで あり、上面開口の４隅に設けた接続片２でケース側面３を枠状に折曲げている。 ケース１内には基板４が装着されており、この基板４上に調整用部品である中間 周波トランス５や半固定抵抗６が装着されており、それぞれトランスコアー５ａ 抵抗ノブ６ａを回動することで所定の調整をするものである。 図８は上部を金属板で覆ったケース２０の上面に部品調整用の開口２１を設け た構造の外観斜視図である。図７と共通の箇所は同一符号を付し重複する説明は 省略する。 図９はケース３０の側面に部品調整用の開口３１を設けた構造の外観斜視図で ある。図９に示すケ−ス３０は、内部に装着した基板４上に基板面と水平に調整 部がある調整用部品７，８が装着されており、ケ−ス側面の開口３１より調整す るようにしたものである。 7 to 10 show an example of a structure in which a component mounted in a conventional electronic device case is adjusted and the component is removed through an opening of the case. FIG. 7 is an external perspective view of a structure in which the top surface of the case is entirely opened. To explain the structure with reference to FIG. 7, reference numeral 1 is a case formed by punching and bending a single metal material. The side surface 3 of the case is bent into a frame shape by the connecting pieces 2 provided at the four corners of the above. A board 4 is mounted in the case 1, and an intermediate frequency transformer 5 and a semi-fixed resistor 6 which are parts for adjustment are mounted on the board 4, and a transformer core 5a and a resistance knob 6a are respectively rotated. To make a predetermined adjustment. FIG. 8 is an external perspective view of a structure in which an opening 21 for adjusting a component is provided on the upper surface of a case 20 whose upper portion is covered with a metal plate. The same parts as those in FIG. 7 are designated by the same reference numerals, and the duplicate description will be omitted. FIG. 9 is an external perspective view of a structure in which an opening 31 for adjusting components is provided on the side surface of the case 30. In the case 30 shown in FIG. 9, adjustment components 7 and 8 each having an adjusting portion horizontal to the board surface are mounted on the board 4 mounted inside, and the case is adjusted through an opening 31 on the side surface of the case. It was done like this.
【０００３】[0003]
しかしながら従来のケースの開口構造においてはそれぞれ以下に示すような不 具合点がある。 図７のケース１は１枚の金属材を打抜き加工し、４隅を接続片２で折曲げ形成 したものであるが、ケース側面の補強がないためケースが変形しやすく、強度が 弱い。また上面の開口が大きな為に、基板上に装着の高周発振回路（図示せず） のケース外への不要輻射が多く、さらに外部よりの妨害電波のケース内への飛込 みも多い。 一方図８及び図９に示す各々のケースは、図８はケース２０の上面に調整用の 開口２１を設けたものであり、図９はケース３０の側面に調整用の開口３１を設 けたものであり、図７に示す構造に比べケースの強度及び高周波の不要輻射及び 飛込みに対しては充分配慮した構造となっている。 しかしながら図８及び図９に示すケースは調整用の開口２１、３１が調整用部 品の外形より小さい為にこの開口を介して、調整用部品５、６、７、８を取外す ことができない。 この対策としては例えば図１０の外観斜視図に示すように調整部品５、６を装 着したケース上面の開口４１を部品の上面寸法より大きくすれば部品の交換取外 しを配慮した開口形状とすることも考えられる。 しかしながら図１０に示すケース構造では部品交換の際には部品の取外し治具 も上面開口４１より挿入するため部品が治具と交錯し、部品と基板の脱着部をケ ス外部からの視認が困難となる。 さらに図６〜図９に示すケース構造では、調整用部品の調整箇所を上面または 側面のいずれかの１面に統一することが必要になる。（図６、図７、図９に示す ケースに装着する調整用部品は調整箇所が基板上方に位置するものを用い、図８ に示すケースに装着する調整用部品は調整箇所が基板と水平方向に位置するもの を用いることになる。）したがって調整用部品調達の自由度が制約され部品のコ ストアップの一因となる。 However, the conventional case opening structures have the following drawbacks. The case 1 in FIG. 7 is formed by punching a single metal material and bending the four corners with the connecting pieces 2. However, since the case side surface is not reinforced, the case is easily deformed and its strength is weak. In addition, since the opening on the top is large, there is a large amount of unwanted radiation outside the case of the high-frequency oscillator circuit (not shown) mounted on the board, and more often interference waves from the outside enter the case. On the other hand, in each of the cases shown in FIGS. 8 and 9, FIG. 8 is a case where the adjustment opening 21 is provided on the upper surface of the case 20, and FIG. 9 is a case where the adjustment opening 31 is provided on the side surface of the case 30. Therefore, compared to the structure shown in FIG. 7, the structure is such that the strength of the case, unnecessary radiation of high frequency, and jump-in are fully considered. However, in the cases shown in FIGS. 8 and 9, since the adjustment openings 21 and 31 are smaller than the outer shape of the adjustment parts, the adjustment parts 5, 6, 7, and 8 cannot be removed through the openings. As a countermeasure against this, for example, as shown in the external perspective view of FIG. 10, if the opening 41 on the upper surface of the case in which the adjusting components 5 and 6 are mounted is made larger than the upper surface dimension of the component, the opening shape in consideration of replacement and removal of the component is obtained. It is also possible to do it. However, in the case structure shown in FIG. 10, when a component is replaced, a jig for removing the component is also inserted through the upper surface opening 41, so that the component intersects with the jig, making it difficult to visually identify the detached portion between the component and the board from the outside of the case. Becomes Further, in the case structure shown in FIGS. 6 to 9, it is necessary to unify the adjustment points of the adjustment parts on one of the upper surface or the side surface. (Adjustment parts mounted on the case shown in FIGS. 6, 7, and 9 are those whose adjustment points are located above the board. The adjustment parts attached to the case shown in FIG. Therefore, the degree of freedom in the procurement of adjustment parts is restricted, which contributes to the cost increase of parts.
