Embodiment 1 FIG.
FIG. 1 is a perspective view showing Embodiment 1 of a housing for storing electrical equipment according to the present invention, FIG. 2 is a front view of the housing according to Embodiment 1, and FIG. FIG. 4 is a cross-sectional view taken along line A-B in FIG. 2.
図１〜図４に示すように、実施の形態１の筐体１０は、電気機器としての電磁接触器８０（図５参照）を収納するための正面が開口した直方体の箱であり、底板１１と側板１２ａ，１２ｂ，１２ｃ，１２ｄを有している。底板１１は、電磁接触器８０が取付けられる部分が、台状に高く形成されている。筐体１０は、電磁接触器８０が外部から影響を受けるのを防止し、電磁接触器８０の充電部及び可動部に人が接近又は接触するのを防止する。 As shown in FIGS. 1 to 4, the housing 10 of the first embodiment is a rectangular parallelepiped box having an open front for housing an electromagnetic contactor 80 (see FIG. 5) as an electrical device. And side plates 12a, 12b, 12c, 12d. The bottom plate 11 is formed so that a portion to which the electromagnetic contactor 80 is attached is formed in a table shape. The housing 10 prevents the electromagnetic contactor 80 from being affected from the outside, and prevents a person from approaching or contacting the charging unit and the movable unit of the electromagnetic contactor 80.
筐体１０は、厚さ０．７ｍｍの鉄板等の金属板をプレス機により絞り成形したものである。図示はしないが、筐体１０には蓋が付属している。電磁接触器８０を筐体１０内に設置し、全ての配線を完了後、蓋を筐体１０の開口部に被せ、電磁接触器８０全体を覆う。蓋は、筐体１０と同様に、厚さ０．７ｍｍの金属板を絞り成形して製作される。 The housing 10 is formed by drawing a metal plate such as an iron plate having a thickness of 0.7 mm using a press. Although not shown, a lid is attached to the housing 10. After the electromagnetic contactor 80 is installed in the housing 10 and all wiring is completed, the lid is placed over the opening of the housing 10 to cover the entire electromagnetic contactor 80. The lid is manufactured by drawing a metal plate having a thickness of 0.7 mm as in the case 10.
電磁接触器８０を筐体１０及び蓋で覆うことにより、外部からの粉塵や水滴等から電磁接触器８０を保護することができる。また、人は、蓋を開けないかぎり電磁接触器８０へ触れることができず、充電部に不用意に触れてしまうのを防止することができる。 By covering the electromagnetic contactor 80 with the housing 10 and the lid, the electromagnetic contactor 80 can be protected from external dust and water droplets. Further, a person cannot touch the electromagnetic contactor 80 unless the lid is opened, and can prevent the charging unit from being inadvertently touched.
なお、電磁接触器８０の配線は、筐体１０の上下に設けられた円形の切込部１２ｅをドライバー等で打抜き、打抜いた開口部を通して行うことができる。円形の切込部１２ｅは、筐体１０の上下の側板１２ｄ，１２ｃに夫々２箇所ずつ設けられている。筐体１０の底板１１には、複数の孔１１ａが設けられていて、孔１１ａを利用して、装置等の垂直面に筐体１０をネジ止め固定することができる。 The wiring of the electromagnetic contactor 80 can be performed through a punched opening by punching circular notches 12e provided at the top and bottom of the housing 10 with a screwdriver or the like. Two circular cut portions 12e are provided on the upper and lower side plates 12d and 12c of the housing 10, respectively. The bottom plate 11 of the housing 10 is provided with a plurality of holes 11a, and the housing 10 can be screwed and fixed to a vertical surface of the apparatus or the like using the holes 11a.
次に、実施の形態１の筐体１０に設けられたＩＥＣレール部５０について説明する。ＩＥＣレール部５０は、電磁接触器８０の底部に設けられている溝（図示せず）に嵌合して電磁接触器８０を筐体１０に取付けるためのものである。 Next, the IEC rail part 50 provided in the housing 10 of the first embodiment will be described. The IEC rail portion 50 is for fitting the electromagnetic contactor 80 to the housing 10 by fitting in a groove (not shown) provided at the bottom of the electromagnetic contactor 80.
ＩＥＣレール部５０は、筐体１０の底板１１をプレス機により加工し、底板１１を切り曲げることにより形成される。実施の形態１のＩＥＣレール部５０は、筐体１０の中央部より上側に設けられた二つの第１のＩＥＣレール部５１と、筐体１０の中央部に設けられた三つの第２のＩＥＣレール部５２と、からなる。 The IEC rail portion 50 is formed by processing the bottom plate 11 of the housing 10 with a press and cutting and bending the bottom plate 11. The IEC rail portion 50 according to the first embodiment includes two first IEC rail portions 51 provided above the central portion of the casing 10 and three second IEC rails provided in the central portion of the casing 10. Rail portion 52.
第１、第２のＩＥＣレール部５１，５２は、底板１１から切り曲げられて夫々上方、下方へ斜めに立ち上がる支持板５１ａ，５２ａと、支持板５１ａ，５２ａの先端から底板１１と平行に夫々上方、下方へ延び電磁接触器８０の夫々の溝に嵌合する矩形板状の嵌合レール部５１ｂ，５２ｂとを有している。支持板５１ａ，５２ａの正面側には、支持板５１ａ，５２ａの剛性を高めるためのプレス成形されたリブ５１ｃ，５２ｃが形成されている。図示はしないが、支持板５１ａの二つのリブ５１ｃの間の裏面側に別のリブを形成してもよい。 The first and second IEC rail portions 51 and 52 are cut and bent from the bottom plate 11 and rise obliquely upward and downward, respectively, and parallel to the bottom plate 11 from the tips of the support plates 51a and 52a, respectively. It has rectangular plate-like fitting rail portions 51b and 52b that extend upward and downward and fit into respective grooves of the electromagnetic contactor 80. On the front side of the support plates 51a and 52a, press-formed ribs 51c and 52c for increasing the rigidity of the support plates 51a and 52a are formed. Although not shown, another rib may be formed on the back side between the two ribs 51c of the support plate 51a.
ＩＥＣレール部５０の幅Ｈ（嵌合レール部５１ｂの先端と嵌合レール部５２ｂの先端との間の距離）は、ＩＥＣレールの幅である３５ｍｍとなっている。ＩＥＣレールの３５ｍｍ幅とすることにより、ＩＥＣ規格に合う電気機器を取り付けることができる。また、嵌合レール部５１ｂの幅ｈ１は、ｈ１＝５ｍｍ、嵌合レール部５２ｂの幅ｈ２は、ｈ２＝２ｍｍ、嵌合レール部５１ｂ，５２ｂの底板１１からの高さｈ３は、ｈ３＝７ｍｍとなっている。 The width H of the IEC rail 50 (the distance between the tip of the fitting rail 51b and the tip of the fitting rail 52b) is 35 mm, which is the width of the IEC rail. By setting the width of the IEC rail to 35 mm, it is possible to attach an electrical device that meets the IEC standard. The width h 1 of the fitting rail portion 51b is h 1 = 5 mm, the width h 2 of the fitting rail portion 52b is h 2 = 2 mm, and the height h 3 from the bottom plate 11 of the fitting rail portions 51b and 52b. Is h 3 = 7 mm.
図１及び図４に示すように、嵌合レール部５１ｂ，５２ｂは、横方向に波形に形成されている。嵌合レール部５１ｂ，５２ｂの板厚は、０．７ｍｍであるが、波形の山の頂部から谷の底部までの外形高さ寸法ｔは、ｔ＝１ｍｍとなっている。また、波形の山の頂部から隣の谷の底部までのピッチは、２ｍｍとなっている。このピッチは、できる限り短い方がよい。ピッチが長いと、嵌合レール部５１ｂ，５２ｂは、単なる歪んだレールとなってしまう。波形に形成された嵌合レール部５１ｂ，５２ｂは、平板状のレールに比べて強度が高い。 As shown in FIG.1 and FIG.4, the fitting rail parts 51b and 52b are formed in the waveform in the horizontal direction. The plate thickness of the fitting rail portions 51b and 52b is 0.7 mm, but the external height dimension t from the top of the corrugated mountain to the bottom of the valley is t = 1 mm. The pitch from the top of the corrugated mountain to the bottom of the adjacent valley is 2 mm. This pitch should be as short as possible. When the pitch is long, the fitting rail portions 51b and 52b are simply distorted rails. The fitting rail portions 51b and 52b formed in the corrugated shape have higher strength than the flat rail.
１ｍｍよりも薄い板厚、例えば、厚さ０．７ｍｍの鉄板をプレス機により絞り成形して筐体１０を作り、筐体１０の底板１１にプレス切り曲げにより平板状の嵌合レール部を成形すると、嵌合レール部の板厚も０．７ｍｍとなる。この平板状の嵌合レール部を波形とし、波形の山の頂部から谷の底部までの外形高さ寸法を１ｍｍとすることにより、１ｍｍの板厚の嵌合レール部として使用することができる。 A plate thickness thinner than 1 mm, for example, a 0.7 mm thick iron plate is formed by drawing with a press machine to form a housing 10, and a flat fitting rail portion is formed by pressing and bending the bottom plate 11 of the housing 10. Then, the plate thickness of the fitting rail portion is also 0.7 mm. By making this flat fitting rail part into a corrugated shape and setting the outer height dimension from the top of the corrugated peak to the bottom of the trough to be 1 mm, it can be used as a fitting rail having a thickness of 1 mm.
また、ＩＥＣレール規格は、板厚１ｍｍの他に、２．３ｍｍ、３ｍｍ等の板厚のものがあるが、本発明の波形の嵌合レール部を採用すれば、波形の高さを変更することにより、板厚２．３ｍｍのレールや、板厚３ｍｍのレールに相当する嵌合レール部が得られる。その場合、波形の山の頂部から隣の谷の底部までのピッチは、適宜変更する。また、実施の形態１の嵌合レール部５１ｂ，５２ｂは波形であるが、この波形は、三角波形や、台形波形や、矩形波形であってもよい。 Further, the IEC rail standard has a plate thickness of 2.3 mm, 3 mm, etc. in addition to a plate thickness of 1 mm. If the corrugated fitting rail portion of the present invention is adopted, the height of the waveform is changed. Thus, a rail with a plate thickness of 2.3 mm and a fitting rail portion corresponding to a rail with a plate thickness of 3 mm are obtained. In this case, the pitch from the top of the corrugated mountain to the bottom of the adjacent valley is changed as appropriate. Moreover, although the fitting rail parts 51b and 52b of Embodiment 1 are waveforms, this waveform may be a triangular waveform, a trapezoidal waveform, or a rectangular waveform.
さらに、実施の形態１の嵌合レール部５１ｂ，５２ｂは、波形の山の頂部から谷の底部までの外形高さ寸法を、ＩＥＣレール規格の１ｍｍとしたが、この外形高さ寸法を、１．０５ｍｍ（１０５％）以上１．３ｍｍ（１３０％）以下としてもよい。１．０５ｍｍ（１０５％）以上１．３ｍｍ（１３０％）以下とする範囲は、嵌合レール部５１ｂ，５２ｂの全範囲でもよいし、一部の範囲でもよい。波形の外形高さ寸法をＩＥＣレール規格の１ｍｍより若干大きくすることにより、１ｍｍ規格に対応した電気機器を取り付ける場合、嵌合レール部５１ｂ，５２ｂの波形の山の頂部及び谷の底部が、電気機器の溝に食込み、電気機器の横ズレが起き難くなる。 Further, in the fitting rail portions 51b and 52b of the first embodiment, the outer height from the top of the corrugated mountain to the bottom of the valley is 1 mm of the IEC rail standard. It may be 0.05 mm (105%) or more and 1.3 mm (130%) or less. The range of 1.05 mm (105%) or more and 1.3 mm (130%) or less may be the entire range of the fitting rail portions 51b and 52b, or may be a partial range. When attaching an electric device corresponding to the 1 mm standard by making the outer height of the corrugation slightly larger than 1 mm of the IEC rail standard, the top of the corrugated mountain and the bottom of the valley of the fitting rail parts 51b and 52b are electrically It becomes difficult to cause a lateral shift of the electric device by biting into the groove of the device.
ＩＥＣレール部５０への電磁接触器８０の取付け方は、まず、電磁接触器８０の一方の溝を第１のＩＥＣレール部５１の嵌合レール部５１ｂへ当てがう。当てがった電磁接触器８０を下方へ押し下げると、嵌合レール部５１ｂが電磁接触器８０の一方の溝に嵌合する。この一方の溝の底には、バネが挿入されていて、バネを圧縮してさらに電磁接触器８０を押し下げると、電磁接触器８０の他方の溝が第２のＩＥＣレール部５２の嵌合レール部５２ｂの先端の位置まで押し下げられる。押し下げる力を弱めると、前記のバネの復元力により、電磁接触器８０が上方へ押し上げられ、嵌合レール部５２ｂが電磁接触器８０の他方の溝に嵌合し、電磁接触器８０が筐体１０に取り付けられる。 In order to attach the electromagnetic contactor 80 to the IEC rail portion 50, first, one groove of the electromagnetic contactor 80 is applied to the fitting rail portion 51 b of the first IEC rail portion 51. When hit Therefore depressing the electromagnetic contactor 80 downward, the fitting rail portion 51b is fitting engagement in one of the grooves of the electromagnetic contactor 80. A spring is inserted into the bottom of the one groove, and when the spring is compressed and the electromagnetic contactor 80 is further pushed down, the other groove of the electromagnetic contactor 80 becomes the fitting rail of the second IEC rail portion 52. It is pushed down to the position of the tip of the part 52b. When the pressing force is weakened, the electromagnetic contactor 80 is pushed upward by the restoring force of the spring, the fitting rail portion 52b is fitted into the other groove of the electromagnetic contactor 80, and the electromagnetic contactor 80 is the housing. 10 is attached.
実施の形態１の電気機器収納用の筐体１０によれば、筐体１０とＩＥＣレール部５０とが一体化された一部品であるため、正規のＩＥＣレールを筐体１０内に設置する必要がなく、部品点数の削減を図ることができる。また、ＩＥＣレール部５０の成形が筐体１０の成形と同時に行えるため、製作工程の削減を図ることができる。 According to the housing 10 for storing electrical equipment according to the first embodiment, since the housing 10 and the IEC rail unit 50 are an integrated part, it is necessary to install a regular IEC rail in the housing 10. Therefore, the number of parts can be reduced. Further, since the formation of the IEC rail portion 50 can be performed simultaneously with the formation of the housing 10, the manufacturing process can be reduced.
実施の形態２．
図５は、実施の形態２の筐体に電磁接触器を収納した状態を示す正面図である。図５に示すように、実施の形態２の筐体２０の底板２１、側板２２ａ，２２ｂ，２２ｃ，２２ｄ及び孔２１ａは、実施の形態１の筐体１０の底板１１、側板１２ａ，１２ｂ，１２ｃ，１２ｄ及び孔１１ａと変わるところはない。実施の形態２の筐体２０が実施の形態１の筐体１０と変わるところは、ＩＥＣレール部６０の第１、第２のＩＥＣレール部６１，６２の嵌合レール部６１ｂ，６２ｂが波形でなく平板状であることである。
Embodiment 2. FIG.
FIG. 5 is a front view showing a state in which the electromagnetic contactor is housed in the housing of the second embodiment. As shown in FIG. 5, the bottom plate 21, side plates 22a, 22b, 22c, and 22d and the hole 21a of the housing 20 of the second embodiment are the same as the bottom plate 11, side plates 12a, 12b, and 12c of the housing 10 of the first embodiment. 12d and the hole 11a. The difference between the case 20 of the second embodiment and the case 10 of the first embodiment is that the fitting rail portions 61b and 62b of the first and second IEC rail portions 61 and 62 of the IEC rail portion 60 have waveforms. It is a flat plate shape.
嵌合レール部６１ｂ，６２ｂの板厚は、筐体２０を成形する板材の厚さと絞り具合によるが、板厚０．７ｍｍの板材を用いて筐体２０及びＩＥＣレール部６０を成形する場合、嵌合レール部６１ｂ，６２ｂの厚さも概ね０．７ｍｍ程度となる。ＩＥＣレールの板厚１ｍｍに対応した電磁接触器８０の場合、板厚０．７ｍｍの板材にて成形した嵌合レール部６１ｂ，６２ｂに溝を嵌合させることは可能であるが、電磁接触器８０の溝と嵌合レール部６１ｂ，６２ｂとの間に若干（０．３ｍｍ）のガタつきを生じることとなる。 The plate thickness of the fitting rail portions 61b and 62b depends on the thickness of the plate material forming the housing 20 and the degree of drawing, but when the housing 20 and the IEC rail portion 60 are formed using a plate material having a plate thickness of 0.7 mm, The thickness of the fitting rail portions 61b and 62b is also approximately 0.7 mm. In the case of the electromagnetic contactor 80 corresponding to the plate thickness of 1 mm of the IEC rail, the groove can be fitted to the fitting rail portions 61b and 62b formed of a plate material having a plate thickness of 0.7 mm. A slight backlash (0.3 mm) occurs between the 80 grooves and the fitting rail portions 61b and 62b.
板厚１ｍｍの板材を用いて筐体２０及びＩＥＣレール部６０を成形する場合、嵌合レール部６１ｂ，６２ｂの厚さも概ね１ｍｍ程度となる。ＩＥＣレールの板厚１ｍｍに対応した電磁接触器８０の場合、板厚１ｍｍの板材にて成形した嵌合レール部６１ｂ，６２ｂに溝を嵌合させると、ガタつきなく嵌合させることができる。 When the casing 20 and the IEC rail portion 60 are formed using a plate material having a thickness of 1 mm, the thickness of the fitting rail portions 61b and 62b is also approximately 1 mm. In the case of the electromagnetic contactor 80 corresponding to the plate thickness of 1 mm of the IEC rail, if the groove is fitted to the fitting rail portions 61b and 62b formed of a plate material having a plate thickness of 1 mm, it can be fitted without backlash.
ＩＥＣレール部６０による電磁接触器８０の取り付けの場合、嵌合レール部６１ｂ，６２ｂの軸方向については、嵌合レール部６１ｂ，６２ｂと電磁接触器８０の溝との嵌合力にもよるが、電磁接触器８０が軸方向に動いてしまう可能性がある。この動きを防止するために、横ズレ防止爪１３ａ，１３ｂ（図２、図５参照）を設置している。この横ズレ防止爪１３ａ，１３ｂを、電磁接触器８０の側面に当てるか、又は、底面の肉盗み部等に挿入することにより、電磁接触器８０の横ズレを防止することができる。 When the electromagnetic contactor 80 is attached by the IEC rail portion 60, the axial direction of the fitting rail portions 61b and 62b depends on the fitting force between the fitting rail portions 61b and 62b and the groove of the electromagnetic contactor 80. The electromagnetic contactor 80 may move in the axial direction. In order to prevent this movement, lateral misalignment prevention claws 13a and 13b (see FIGS. 2 and 5) are installed. The lateral displacement of the electromagnetic contactor 80 can be prevented by applying the lateral displacement prevention claws 13a and 13b to the side surface of the electromagnetic contactor 80 or by inserting the lateral contact prevention claws 13a and 13b into a meat stealing portion or the like on the bottom surface.
