従来のＤＩＮレ一ル取付け構造を図１０乃至図１３に示す。   A conventional DIN rail mounting structure is shown in FIGS.

この従来のＤＩＮレ一ル取付け構造は、機器、例えば電源機器３０の筐体３０Ａの背面部３０Ｂに装着されたレール係合装置３１を備えており、レール係合装置３１のプレート本体３１Ａには、横方向に沿う係合凹部３２が形成してあり、係合凹部３２の、図１０において上側の辺部には係合爪部３３が形成してある。また、プレート本体３１Ａには、その下側部に係合凹部３２に直交するようにしてスライダロック用溝部３４が形成してある。   This conventional DIN rail mounting structure includes a rail engaging device 31 mounted on a back surface portion 30B of a casing 30A of a device, for example, a power supply device 30, and the plate main body 31A of the rail engaging device 31 includes An engaging recess 32 is formed along the lateral direction, and an engaging claw 33 is formed on the upper side of the engaging recess 32 in FIG. The plate main body 31A has a slider locking groove 34 formed on the lower side thereof so as to be orthogonal to the engaging recess 32.

そして、スライダロック用溝部３４には、スライダロック部材３５がばね部材３６により上方向に付勢された状態で摺動可能に設けてあり、このスライダロック部材３５の先端部に設けた係合爪部３７が係合凹部３２内に突入している。   A slider lock member 35 is slidably provided in the slider lock groove 34 while being urged upward by a spring member 36. An engagement claw provided at the tip of the slider lock member 35 is provided. The part 37 protrudes into the engaging recess 32.

そして、電源機器３０を手で持って、レール係合装置３１の係合爪部３３をＤＩＮレール４０の上側の係合片部４０Ｂに引っ掛けた状態で、電源機器３０をＤＩＮレール４０側に移動して、スライダロック部材３５の係合爪部３７をＤＩＮレール４０の下側の係合片部４０Ｃに押し付けることにより、この押付力の、係合爪部３７の斜面部３７ａで生じる分力で、ばね部材３６のばね力に抗してスライダロック部材３５を下方に移動させ、ＤＩＮレール４０を係合凹部３２に挿入し、ばね部材３６のばね力でスライダロック部材３５を上方に移動させて、係合爪部３７を係合片部４０Ｃに係合させることで、電源機器３０がＤＩＮレール４０に取付けてある。   Then, holding the power supply device 30 by hand, the power supply device 30 is moved to the DIN rail 40 side in a state where the engaging claw portion 33 of the rail engaging device 31 is hooked on the engaging piece portion 40B on the upper side of the DIN rail 40. Then, by pressing the engaging claw portion 37 of the slider lock member 35 against the lower engaging piece portion 40 </ b> C of the DIN rail 40, this pressing force is a component force generated at the inclined surface portion 37 a of the engaging claw portion 37. The slider lock member 35 is moved downward against the spring force of the spring member 36, the DIN rail 40 is inserted into the engagement recess 32, and the slider lock member 35 is moved upward by the spring force of the spring member 36. The power supply device 30 is attached to the DIN rail 40 by engaging the engaging claw portion 37 with the engaging piece portion 40C.

この場合、レール係合装置３１の幅は、電源機器３０の筐体３０Ａの背面部３０Ｂの幅より狭いために、図１１に示すようにレール係合装置３１の左、右方では背面部３０ＢとＤＩＮレール４０の上、下側の係合片部４０Ｂ、４０Ｃとの間には隙間ｔが生じている。   In this case, since the width of the rail engagement device 31 is narrower than the width of the back surface portion 30B of the housing 30A of the power supply device 30, the back surface portion 30B is on the left and right sides of the rail engagement device 31 as shown in FIG. And a gap t between the upper and lower engaging pieces 40B, 40C.

また、従来のＤＩＮレ一ル取付け構造としては、ビルディングブロック構造のプログラマブルコントローラ用ユニットのスライダロック装置がある。このスライダロック装置は、ユニット本体の背面部に、係合凹部とスライダロック用溝部とを設け、このスライダロック用溝部に、スライダロック部材を移動可能に設けると共に、スライダロック部材を係合凹部側に保持するカム機構を設けて、係合凹部に係合されたＤＩＮレールを、係合凹部の係合爪部とスライダロック部材の係合爪部とで挟むようにしたものである（特許文献１参照）
特開平６−２３０８０７号公報 As a conventional DIN rail mounting structure, there is a slider lock device for a programmable controller unit having a building block structure. In this slider lock device, an engagement recess and a slider lock groove are provided on the back surface of the unit body, and a slider lock member is movably provided in the slider lock groove, and the slider lock member is disposed on the engagement recess side. The DIN rail engaged with the engaging recess is sandwiched between the engaging claw portion of the engaging recess and the engaging claw portion of the slider lock member (Patent Document). 1)
JP-A-6-230807

しかしながら、従来の前者のＤＩＮレ一ル取付け構造にあっては、レール取付け装置３１の幅が、電源機器３０の筐体３０Ａの背面部３０Ｂの幅より狭くしてあることにより、レール係合装置３１の左、右方では背面部３０ＢとＤＩＮレール４０の上、下側の係合片部４０Ｂ、４０Ｃとの間には隙間ｔが生じている。このために、電源機器３０の左、右端部を前後方向に動かす力が加わって、横揺れが生じた場合には、隙間ｔ分だけ横揺れが増幅されて、電源機器３０の内部構造や内部回路が破損し、また、ＤＩＮレール４０を挟んでいるレール係合装置３１の係合爪部３３及びスライダロック部材３５の係合爪部３７等のＤＩＮレール取付け部分の破損を招くという問題点があった。   However, in the former former DIN rail mounting structure, the rail engaging device 31 is narrower than the back surface 30B of the housing 30A of the power supply device 30, so that the rail engaging device On the left and right sides of 31, there is a gap t between the back surface portion 30 </ b> B and the upper and lower engaging piece portions 40 </ b> B and 40 </ b> C of the DIN rail 40. For this reason, when a force is generated to move the left and right ends of the power supply device 30 in the front-rear direction and a roll occurs, the roll is amplified by the gap t, and the internal structure and the internal structure of the power supply device 30 are increased. There is a problem that the circuit is broken and the DIN rail mounting portions such as the engaging claw portion 33 of the rail engaging device 31 and the engaging claw portion 37 of the slider lock member 35 sandwiching the DIN rail 40 are damaged. there were.

また、図１３に示すように、レール係合装置３１の幅寸法Bを、電源機器３０の筐体３０Ａの背面部３０Ｂの幅と同じにして上記した隙間ｔが生じないようにした場合には、その機器毎にレール係合装置３１を設計しなければならず、標準化、省資源化を妨げ、コストアップになるという問題点があった。   As shown in FIG. 13, when the width B of the rail engaging device 31 is the same as the width of the back surface 30B of the housing 30A of the power supply device 30 so that the above-described gap t does not occur. The rail engaging device 31 must be designed for each of the devices, which hinders standardization and resource saving and increases the cost.

また、従来の後者のＤＩＮレ一ル取付け構造にあっては、ユニット本体の背面部に、係合凹部とスライダロック用溝部とスライダロック部材とカム機構とからなるレール係合部が直接に設けてあるために、その機器毎に、ユニット本体の背面部にレール係合部を設計しなければならず、標準化、省資源化を妨げ、コストアップになるという問題点があった。   Further, in the latter latter DIN rail mounting structure, a rail engagement portion including an engagement recess, a slider lock groove, a slider lock member, and a cam mechanism is directly provided on the back surface of the unit body. Therefore, for each of the devices, a rail engaging portion must be designed on the back surface of the unit main body, which hinders standardization and resource saving and increases costs.

本発明は、上記した従来の問題点に着目して成されたものであって、その目的とするところは、機器の背面部幅より狭い巾寸法を荷設定形成されたレール係合装置を使用しても、振動による機器の内部構造や内部回路の破損、振動によるレール係合手段の破損を未然に防ぐことができるＤＩＮレ一ル取付け構造を提供することである。   The present invention has been made paying attention to the above-mentioned conventional problems, and the object of the present invention is to use a rail engagement device in which a width dimension narrower than the width of the back part of the device is set.

For this reason, it is possible to prevent damage to the internal structure and internal circuit of the device due to vibration and damage to the rail engaging means due to vibration, and to standardize the rail engaging means.

また、本発明に係るＤＩＮレ一ル取付け構造は、上記した本発明に係るＤＩＮレ一ル取付け構造において、振動吸収部が、ＤＩＮレール側に突出するように、ＤＩＮレール取付け面に形成した突起部により構成している。   Further, the DIN rail mounting structure according to the present invention is a projection formed on the DIN rail mounting surface so that the vibration absorbing portion protrudes to the DIN rail side in the above-described DIN rail mounting structure according to the present invention.

レール係合装置装着部３には取付け用ねじ孔４ａ、４ｂを用いてレール係合手段であるレール係合装置５が装着してある。すなわち、レール係合装置５はプレート本体５Ａを有しており、プレート本体５Ａには、上下方向の略中央部に、左右方向（横方向）に沿う係合凹部６が形成してあり、係合凹部６の上側の辺部には係合爪部７が形成してある。   The rail engaging device mounting portion 3 is mounted with a rail engaging device 5 as rail engaging means using mounting screw holes 4a and 4b. That is, the rail engaging device 5 has a plate main body 5A, and the plate main body 5A is formed with an engaging recess 6 along the left-right direction (lateral direction) at a substantially central portion in the vertical direction. An engaging claw portion 7 is formed on the upper side portion of the joint recess 6.

また、プレート本体５Ａには、その上側にねじ用孔８が設けてあるし、プレート本体５Ａには、その下側に係合凹部６に直交するようにしてスライダロック用溝部９が形成してある。   The plate body 5A is provided with a screw hole 8 on the upper side, and the plate body 5A has a slider lock groove 9 formed on the lower side thereof so as to be orthogonal to the engaging recess 6. is there.

スライダロック用溝部９にはねじ用孔１０が形成してある。   A screw hole 10 is formed in the slider locking groove 9.

そして、スライドロック用溝部９には、スライドロック部材１１がばね部材１２により上方向に付勢された状態で摺動可能に設けてあり、スライドロック部材１１の先端部の係合爪部１３が係合凹部６内に突入している。   The slide lock groove 9 is slidably provided with a slide lock member 11 biased upward by a spring member 12, and an engagement claw portion 13 at the tip of the slide lock member 11 is provided. It enters into the engaging recess 6.

係合爪部１３は、その表面が斜面部１３ａにしてある。   The surface of the engaging claw portion 13 is a slope portion 13a.

また、スライドロック部材１１には開口部１４が形成してあり、この開口部１４内にねじ用孔１０が位置している。   An opening 14 is formed in the slide lock member 11, and the screw hole 10 is located in the opening 14.

そして、レール係合装置５は、ねじ用孔８、１０に挿入したねじ部材１７、１８を取付け用ねじ孔４ａ、４ｂに螺合することでレール係合装置装着部３に取付けてある。   The rail engagement device 5 is attached to the rail engagement device mounting portion 3 by screwing the screw members 17 and 18 inserted into the screw holes 8 and 10 into the attachment screw holes 4a and 4b.

また、筐体２Ａの背面部２ａには、レール係合装置装着部３を中央にして左、右における係合片部１Ｃのライン上（二点鎖線参照）に位置させて一対の振動吸収部である突起部１５が形成してある。 In addition, the rear surface portion 2a of the housing 2A has a pair of vibration absorbing portions positioned on the line of the engagement piece portion 1C on the left and right (see the two-dot chain line) with the rail engagement device mounting portion 3 in the center. A projection 15 is formed.

これらの突起部１５は、筐体２Ａの背面部２ａを構成する板材２ｂを台形形状に打ち出して形成してあり、突起部１５の頂部は平坦な干渉部１５ａにしてある。   These protrusions 15 are formed by punching a plate material 2b constituting the back surface 2a of the housing 2A into a trapezoidal shape, and the top of the protrusion 15 is a flat interference part 15a.

そして、突起部１５には、両持ち形状にすることで弾性が付与されている。   And the elasticity is provided to the projection part 15 by making it a doubly-supported shape.

なお、突起部１５の高さ寸法は、電源機器２のＤＩＮレール１への取付け時に、突起部１５がＤＩＮレール１の係合片部１Ｃに干渉することがないように、背面部２aとＤＩＮレール１の係合片部１Ｃとの間隔よりわずかに低く設定してある。   The height of the protrusion 15 is such that the protrusion 15 does not interfere with the engaging piece 1C of the DIN rail 1 when the power supply device 2 is attached to the DIN rail 1. The distance between the rail 1 and the engagement piece 1C is set slightly lower.

一対の突起部１５の形成位置は、ＤＩＮレール１にレール係合装置５が係合した際に、突起部１５の干渉部１５ａがＤＩＮレール１の下側の係合片部１Ｃに対向する所である。   When the rail engaging device 5 is engaged with the DIN rail 1, the formation position of the pair of protruding portions 15 is such that the interference portion 15a of the protruding portion 15 faces the engaging piece portion 1C on the lower side of the DIN rail 1. It is.

そして、電源機器２を手で持って、レール係合装置５の係合爪部７をＤＩＮレール１の係合片部１Ｂに引っ掛けた状態で、電源機器２をＤＩＮレール１側に移動して、スライドロック部材１１の係合爪部１３をＤＩＮレール１の係合片部１Ｃに押し付けることにより、この押付力の、係合爪部１３の斜面部１３ａで生じる分力で、ばね部材１２のばね力に抗してスライドロック部材１１を下方に移動し、ＤＩＮレール１を係合凹部６に係合し、ばね部材１２のばね力でスライドロック部材１１を上方に移動して、係合爪部１３を係合片部１Ｃに係合することで電源機器２がＤＩＮレール１に取付けてある。   Then, while holding the power supply device 2 by hand, the power supply device 2 is moved to the DIN rail 1 side in a state where the engagement claw portion 7 of the rail engagement device 5 is hooked on the engagement piece portion 1B of the DIN rail 1. By pressing the engaging claw portion 13 of the slide lock member 11 against the engaging piece portion 1C of the DIN rail 1, the component force generated by the inclined surface portion 13a of the engaging claw portion 13 of this pressing force is used. The slide lock member 11 is moved downward against the spring force, the DIN rail 1 is engaged with the engagement recess 6, the slide lock member 11 is moved upward by the spring force of the spring member 12, and the engagement claw The power supply device 2 is attached to the DIN rail 1 by engaging the portion 13 with the engaging piece portion 1C.

このようにして、電源機器２をＤＩＮレール１に取付けた状態では、一対の突起部１５の平坦な干渉部１５ａとＤＩＮレール１の下側の係合片部１Ｃとの間には僅かな隙間が存在する。   Thus, in a state where the power supply device 2 is attached to the DIN rail 1, a slight gap is formed between the flat interference portion 15a of the pair of protrusions 15 and the engaging piece portion 1C on the lower side of the DIN rail 1. Exists.

そして、電源機器２の左、右端部を前後方向に動かす振動が加わって、横揺れを生じた場合には、一対の突起部１５の干渉部１５ａがＤＩＮレール１の下側の係合片部１Ｃに干渉して、この横揺れを早い段階で吸収する。   And when the vibration which moves the left and right edge part of the power supply device 2 to the front-back direction is added and rolling occurs, the interference part 15a of a pair of projection part 15 will be the engagement piece part below DIN rail 1 Interference with 1C and absorb this roll at an early stage.
