電子機器筺体の使い勝手を向上させるため、電子機器筺体の取り付け方法をねじ止め式とマグネット固定式とに選択できるようにする。しかしながら、ねじ止め式として用いるために、ねじ挿通孔を、マグネット固定式として用いるために、マグネットを取り付けるための取り付け部とを形成する必要があり、その加工に手間がかかるという欠点があった。また、ねじ挿通孔とマグネット取り付け部とをそれぞれ形成することで、電子機器筺体の内部に機器を取り付けることのできる部分が限定されてしまうという欠点があった。   In order to improve the usability of the electronic device housing, the mounting method of the electronic device housing can be selected from the screwing type and the magnet fixing type. However, in order to use it as a screwing type, it is necessary to form an attachment part for attaching a magnet in order to use the screw insertion hole as a magnet fixing type. Moreover, there was a fault that the part which can attach an apparatus to the inside of an electronic device housing will be limited by forming a screw insertion hole and a magnet attachment part, respectively.

そこで本発明は、電子機器筺体の取り付けは、ねじ止め式、マグネット固定式のどちらも可能で、加工も簡単である電子機器筺体の取り付け構造を提供することを目的とし、電子機器筺体の裏面には、マグネットの取り付け凹部を設けると共に、取り付け凹部の略中央部にねじ挿通孔を設けたことを特徴とする。   Therefore, the present invention has an object to provide an electronic device housing mounting structure that can be attached to the electronic device housing by either a screwing type or a magnet-fixed type, and can be easily processed. Is characterized in that a magnet mounting recess is provided and a screw insertion hole is provided in a substantially central portion of the mounting recess.

本発明に係る電子機器筺体の取り付け構造は、電子機器筺体の裏面には、マグネットの取り付け凹部を設けると共に、取り付け凹部の略中央部にねじ挿通孔を設けたため、電子機器筺体の加工が簡単であるので、安価に使い勝手の良い電子機器筺体が提供できるようになる。また、電子機器筺体を分電盤にねじ止めするためと、マグネットを電子機器筺体に固定するためとにねじ挿通孔を共用することで、電子機器筺体の内部スペースを機器の配置に有効に利用することができるようになり、小型化の進む電子機器にとって、大きな効果が得られる。   The mounting structure of the electronic device housing according to the present invention is provided with a magnet mounting recess on the back surface of the electronic device housing and a screw insertion hole in the substantially central portion of the mounting recess, so that the processing of the electronic device housing is easy. Therefore, it is possible to provide an electronic device housing that is easy to use at low cost. In addition, the internal space of the electronic device housing is effectively used for device placement by sharing the screw insertion holes for screwing the electronic device housing to the distribution board and fixing the magnet to the electronic device housing. Therefore, a great effect can be obtained for electronic devices that are becoming smaller.

本発明に係る電子機器筺体の取り付け構造の実施例を図１〜図３の添付図面に基いて説明する。図１は、電子機器筺体をねじ止め式として用いる様子を示し、図２〜図３は、電子機器筺体をマグネット固定式として用いる様子を示している。   An embodiment of an electronic device housing mounting structure according to the present invention will be described with reference to the accompanying drawings of FIGS. FIG. 1 shows a state in which the electronic device housing is used as a screwing type, and FIGS. 2 to 3 show a state in which the electronic device housing is used as a magnet fixing type.

本発明に係る電子機器筺体１は、基板等の電子機器を載置する基台２と、この基台２前面開口を被覆するカバー体３とから構成される。このような電子機器筺体１は、例えば電力使用量を表示する機器として用いられ、分電盤のキャビネット内部やキャビネットの扉に取り付けられる。   An electronic device housing 1 according to the present invention includes a base 2 on which an electronic device such as a substrate is placed, and a cover body 3 that covers the front opening of the base 2. Such an electronic device housing 1 is used, for example, as a device that displays the amount of power used, and is attached to the inside of the cabinet of the distribution board or the door of the cabinet.

図３に示すように、電子機器筺体１の基台２の裏面には、マグネット４を取り付けるためのマグネット取り付け凹部５を形成している。大きさや数については、電子機器筺体１の大きさに合わせて適宜変更可能である。図３では、上下二ケ所に形成している。マグネット取り付け凹部５の略中央部には、ねじ挿通孔６を設ける。また、図１〜図２に示すように、カバー体３にもこのねじ挿通孔６に対向する位置に挿通孔７を形成する。   As shown in FIG. 3, a magnet mounting recess 5 for mounting the magnet 4 is formed on the back surface of the base 2 of the electronic device housing 1. About a magnitude | size and a number, according to the magnitude | size of the electronic device housing | casing 1, it can change suitably. In FIG. 3, it forms in two places up and down. A screw insertion hole 6 is provided at a substantially central portion of the magnet mounting recess 5. As shown in FIGS. 1 and 2, the cover body 3 is also formed with an insertion hole 7 at a position facing the screw insertion hole 6.

電子機器筺体１を分電盤内部にねじ止めして固定する場合には、基台２正面開口をカバー体３で被覆した状態で、カバー体３の正面から挿通孔７とねじ挿通孔６とにそれぞれねじ８を挿通し、分電盤に設置されている機器取り付け板（図示せず）にねじこんで固定する。このとき用いるねじ８は、カバー体３、基台２を貫通し、機器取り付け板に到達、ねじこみできる長さである。   When the electronic device housing 1 is screwed and fixed inside the distribution board, the insertion hole 7 and the screw insertion hole 6 are formed from the front of the cover body 3 with the front opening of the base 2 covered with the cover body 3. Each of the screws 8 is inserted into and fixed to a device mounting plate (not shown) installed on the distribution board by screwing. The screw 8 used at this time has a length that penetrates the cover body 3 and the base 2 and can reach and be screwed into the device mounting plate.

また、電子機器筺体１を分電盤の扉等の金属に固定または、仮設置する場合には、ねじ挿通孔６には、スペーサ９を差し込む。スペーサ９は、マグネット４を支持する機能と、マグネット４を電子機器筺体１に固定するためのねじ受けの機能を持つ。基台２裏面に形成したマグネット取り付け凹部５に略中央部に挿通穴１０を有するマグネット４を置き、小ねじ１１を挿通し、ねじ挿通孔６に差し込んだスペーサ９とでマグネット４を固定する。そのマグネット４の吸着力で分電盤に取り付ける。マグネット４を固定する小ねじ１１は、電子機器筺体１を分電盤に取り付けるときに、分電盤に傷をつけないよう、マグネット４表面から突出しない頭部の平らなものが良い。   Further, when the electronic device housing 1 is fixed or temporarily installed on a metal such as a door of a distribution board, a spacer 9 is inserted into the screw insertion hole 6. The spacer 9 has a function of supporting the magnet 4 and a function of a screw receiver for fixing the magnet 4 to the electronic device housing 1. A magnet 4 having an insertion hole 10 at a substantially central portion is placed in a magnet mounting recess 5 formed on the back surface of the base 2, a machine screw 11 is inserted, and the magnet 4 is fixed with a spacer 9 inserted into the screw insertion hole 6. The magnet 4 is attached to the distribution board by the attractive force. The small screw 11 that fixes the magnet 4 is preferably a flat head that does not protrude from the surface of the magnet 4 so as not to damage the distribution board when the electronic device housing 1 is attached to the distribution board.

電子機器筺体１を分電盤に取り付ける場合、ねじ止め式で確実に固定する場合と、マグネット４で取り付け取り外しも可能にする場合と、どちらか片方の方法を選択できれば良いため、電子機器筺１体を分電盤にねじ止めするためと、マグネット４を電子機器筺体１に固定するためと、ねじ挿通孔６を共用することができる。   When the electronic device housing 1 is attached to the distribution board, it is only necessary to select one of the methods, that is, a case where the electronic device housing 1 is securely fixed by a screwing type, or a case where attachment / detachment is possible with the magnet 4. The screw insertion hole 6 can be shared for screwing the body to the distribution board, for fixing the magnet 4 to the electronic device housing 1.

電子機器筺体１を分電盤にねじ止めするためと、マグネット４を電子機器筺体１に固定するためとにねじ挿通孔６を共用することで、基台２のスペースを機器の配置に有効に利用できるようになる。   By using the screw insertion hole 6 for screwing the electronic device housing 1 to the distribution board and fixing the magnet 4 to the electronic device housing 1, the space of the base 2 can be effectively used for device placement. It becomes available.
