Description

本発明は、内部スイッチ構成体を収容するスイッチケース装置に関し、特に、例えば産業機械が設置される部屋の出入口などに取付けられて、当該出入口の扉が開かれる時には当該産業機械への電源の供給を停止するようになしたドア用スイッチを構成するスイッチケース装置に関するものである。   The present invention relates to a switch case device that accommodates an internal switch structure, and in particular, is attached to an entrance of a room where an industrial machine is installed, for example, and supplies power to the industrial machine when the door of the entrance is opened. The present invention relates to a switch case device constituting a door switch adapted to stop the operation.

従来、この種のスイッチケース装置は、内部スイッチ構成体を収納するために開口部を有するボックス状のスイッチ収容筐体と該スイッチ収容筐体の前記開口部を閉塞するように該スイッチ収容筐体に装着する蓋体とを有して構成しており、前記蓋体および前記スイッチ収容筐体に互いに連通する取付け孔をそれぞれ形成すると共に、前記蓋体側の取付け孔に挿入したタッピングねじがスイッチ収容筐体側の取付け孔にねじ山を形成しながら螺合して、前記スイッチ収容筐体に前記蓋体を装着固定するものが知られている。   Conventionally, this type of switch case device has a box-shaped switch housing case having an opening for housing an internal switch structure, and the switch housing case so as to close the opening of the switch housing case. And mounting holes that communicate with each other in the lid body and the switch housing housing, and a tapping screw inserted into the mounting hole on the lid body accommodates the switch housing. It is known that the lid is mounted and fixed to the switch housing case by screwing in a mounting hole on the case side while forming a screw thread.

これによれば、スイッチ収容筐体に対して蓋体をねじ締め取付けを行う際に、規定以上のねじ締めトルクでねじ締めを行うと、スイッチ収容筐体側の取付け孔がタッピングねじにより形成されたねじ山が作成されてしまい、蓋体がスイッチ収容筐体に装着固定できなくなってしまうことがあり、このときのねじ締めトルク強度は、スイッチ収容筐体の材質に依存することになる。   According to this, when the cover is screwed and attached to the switch housing, when the screw is tightened with a screw tightening torque exceeding a specified value, the mounting hole on the switch housing is formed by the tapping screw. A screw thread may be created, and the lid may not be attached and fixed to the switch housing. The screw tightening torque strength at this time depends on the material of the switch housing.

そこで、従来において、スイッチ収容筐体側の取付け孔に、ねじ孔部が対向するようにナット部材を前記スイッチ収容筐体に熱加締め或いはスイッチ収容筐体の成形時にインサート成形により固設しておくものが知られている。   Therefore, conventionally, a nut member is fixed to the switch housing case by heat caulking or insert molding when the switch housing case is molded so that the screw hole portion faces the mounting hole on the switch housing case side. Things are known.

かかる構成を有する従来の技術では、ナット部材を使用していることから、タッピングねじによる場合と比較して、ねじ締めトルク強度を上げることができ、このときのねじ締めトルク強度がスイッチ収容筐体の材質に依存することがなくなり、常時蓋体をスイッチ収容筐体に確実に装着することができることになる。   In the conventional technology having such a configuration, since the nut member is used, the screw tightening torque strength can be increased as compared with the case of using the tapping screw. Therefore, the lid can always be securely attached to the switch housing.

しかしながら、前記ナット部材は、熱加締めあるいはインサート成形によりスイッチ収容筐体に完全固着状態で設置或いはスイッチ収容鏡体側の取付け孔とスイッチ収容筐体側のナット部材との間で芯ぶれが生じる場合があり、このような場合、蓋体をスイッチ収容筐体に正規位置で取付けることができない場合や延いては取り付け不可能となってしまうことにもなりかねないことになる。   However, the nut member may be installed in a state of being completely fixed to the switch housing case by heat caulking or insert molding, or a runout may occur between the mounting hole on the switch housing body and the nut member on the switch housing case side. In such a case, there is a possibility that the lid cannot be attached to the switch housing in the normal position or that it cannot be attached.

そこで、改良された従来技術として、ナット部材をスイッチ収容筐体に完全固着することをやめ、スイッチ収容筐体側にその取付け孔に連通するようなナット部材収容凹部を形成し、このナット部材収容凹部内にナット部材を移動可能に収容するようにして、ナット部材収容凹部の開口を別体の覆い蓋にて閉塞するように構成するものが知られている。   Therefore, as an improved prior art, the nut member is not completely fixed to the switch housing, and a nut member housing recess that communicates with the mounting hole is formed on the switch housing housing. There is known a configuration in which a nut member is movably accommodated therein and the opening of the nut member accommodation recess is closed with a separate cover lid.

かかる従来の技術においては、ナット部材はナット部材収容凹部内において移動可能に構成されているために、もし、スイッチ収容筐体あるいは蓋体の成形誤差などにより、蓋体側の取付け孔とスイッチ収容筐体側のナット部材との間で芯ぶれが生じたとしても、ナット部材が適宜移動して、当該芯ぶれを解消して、常時蓋体をスイッチ収容筐体に確実に装着することができることになる（非特許文献１を参照）。
ＩＤＥＣ株式会社発行のＨＳ５Ｂ形小形安全スイッチの商品型録 （２００７年（平成１９年）６月１日発行） （http://WWW.idec.com/japan/参照） In such a conventional technique, the nut member is configured to be movable in the nut member housing recess, and therefore, if the switch housing housing or the lid body is formed due to a molding error or the like, the mounting hole on the lid body and the switch housing housing are arranged. Even if runout occurs with the body side nut member, the nut member can be moved appropriately to eliminate the runout, and the lid can always be securely attached to the switch housing. (See Non-Patent Document 1).
Product model of HS5B type small safety switch issued by IDEC Corporation (issued June 1, 2007) (see http://WWW.idec.com/japan/)

しかしながら、改良された従来技術によれば、ナット部材収容凹部の開口部を別体の覆い蓋により閉塞する必要があり、このために、部品点数が増加する上、覆い蓋の取付け工数も加算されることになって、部品コストを上昇させてしまうことになる。   However, according to the improved prior art, it is necessary to close the opening of the nut member receiving recess with a separate cover lid, which increases the number of parts and adds the man-hour for mounting the cover lid. As a result, the cost of parts increases.

そこで、本発明は、スイッチ収容筐体や蓋体における成形誤差を吸収するために、ナット部材をスイッチ収容筐体のナット部材収容凹部内において移動可能に収容するとともに、従来の技術における別体の覆い蓋を廃止することによって、部品点数の軽減延いては部品コストの低減が達し得るスイッチケース装置を提供することを目的としている。   Therefore, the present invention accommodates a nut member movably in a nut member housing recess of the switch housing housing in order to absorb molding errors in the switch housing housing and the lid body, An object of the present invention is to provide a switch case device in which the number of components can be reduced and the cost of components can be reduced by eliminating the cover lid.

本発明に係るスイッチケース装置は、スイッチケースを、内部スイッチ構成体を収納するために開口部を有するボックス状のスイッチ収容筐体と、該スイッチ収容筐体の前記開口部を閉塞するように前記スイッチ収容筐体に装着する蓋体とを有して構成しており、前記蓋体および前記スイッチ収容筐体に互いに連通する取付け孔をそれぞれ形成すると共に、前記スイッチ収容筐体側の取付け孔にナット部材のねじ孔部が対向するように該ナット部材を前記スイッチ収容筐体に設けて、前記蓋体側およびスイッチ収容筐体側の前記取付け孔から取付けビスを挿入して、該取付けビスを前記ナット部材に螺合することにより前記蓋体を前記スイッチ収容筐体に装着して構成するスイッチケース装置であって、前記スイッチ収容筐体に、当該スイッチ収容筐体側の前記取付け孔が連通すると共に前記ナット部材を回り止めした状態で収容するナット部材収容凹部を形成し、該ナット収容凹部を臨むように前記スイッチ収容筐体に突起を突設しており、該突起の先端部を熱変形等により圧潰片部に形成して、該圧潰片部により前記ナット部材を、当該ねじ孔部が前記スイッチ収容筐体側の前記取付け孔に対向するように位置調整可能に係合して落下防止されるように構成したことを特徴とするものである。   In the switch case device according to the present invention, the switch case includes a box-shaped switch housing case having an opening for housing the internal switch structure, and the opening of the switch housing case is closed. A lid that is attached to the switch housing, and each has a mounting hole that communicates with the lid and the switch housing, and a nut in the mounting hole on the switch housing The nut member is provided in the switch housing case so that the screw hole portions of the member face each other, a mounting screw is inserted from the mounting hole on the lid side and the switch housing case side, and the mounting screw is inserted into the nut member. The switch case device is configured by mounting the lid body on the switch housing case by screwing to the switch housing case. The mounting hole on the housing case communicates and a nut member housing recess for housing the nut member in a state of being prevented from rotating is formed, and a projection is provided on the switch housing housing so as to face the nut housing recess. The tip of the protrusion is formed into a crushing piece part by thermal deformation or the like, and the nut member is positioned by the crushing piece part so that the screw hole part faces the mounting hole on the switch housing case side. It is configured so that it can be adjusted and engaged to prevent falling.

上記のように構成する本発明によれば、ナット部材は、スイッチ収容筐体に一体に形成した突起の先端部を熱変形等により圧潰することによって形成された圧潰片部により、ナット部材収容凹部内において位置調整可能に係合されることから、従来の技術における別体の覆い蓋を廃止することができ、部品点数や取付け工数を軽減することが期待でき、しかも、ナット部材収容凹部内においてナット部材が適宜位置調整可能に係合設置されていることから、スイッチ収容筐体或いは蓋体の成形時に成形誤差等により、スイッチ収容筐体側の取付け孔とナット部材収容凹部内におけるナット部材のねじ孔部との間で芯ぶれが生じたとしても、ナット部材がナット部材収容凹部内を適宜位置修正されて、当該芯ぶれを解消し、常時蓋体をスイッチ収容筐体に確実に装着することができることになる。   According to the present invention configured as described above, the nut member is a nut member accommodating recess formed by a crushing piece portion formed by crushing a tip portion of a protrusion formed integrally with the switch housing case by thermal deformation or the like. Since it is engaged so that the position can be adjusted in the inside, it is possible to eliminate the separate cover lid in the prior art, and it can be expected to reduce the number of parts and mounting man-hours, and in the nut member receiving recess Since the nut member is engaged and installed so that the position can be adjusted as appropriate, the screw of the nut member in the mounting hole on the switch housing housing side and the nut member housing recess due to a molding error or the like when molding the switch housing housing or the lid. Even if runout occurs between the hole and the nut member, the position of the nut member is appropriately corrected in the nut member receiving recess to eliminate the runout, and the lid is always switched. So that it is possible to reliably mount the volume enclosure.

図１において、本発明に係る実施例を採用したスイッチケース装置は、ドアスイッチとして構成するものであり、不図示のスイッチ構成体を収容すべくボックス状のスイッチ収容筐体１と、スイッチ収容筐体１の前面部を開口して形成された開口部１ａを閉塞する蓋体２とから構成されており、上部側にスイッチ収容筐体として不図示の内部スイッチ構造体を収容すべく、その前面が開口されたボックス形状のスイッチ収容筐体１とスイッチ収容筐体１の前面部１Ｂにおける開口部１ａを開閉する蓋体３とを有して構成している。   In FIG. 1, a switch case device employing an embodiment according to the present invention is configured as a door switch, and includes a box-shaped switch housing case 1 and a switch housing case for housing a switch structure (not shown). A lid 2 that closes the opening 1a formed by opening the front portion of the body 1, and in order to accommodate an internal switch structure (not shown) as a switch housing case on the upper side. And a lid 3 that opens and closes the opening 1a in the front surface portion 1B of the switch housing 1.

スイッチ収容筐体１の上部側の側面部１Ａには、産業機械等が配置される部屋の出入口ドアの開閉によって前記内部スイッチ構造体を開閉操作するキー操作体を収容するヘッドブロック筐体３が配設されている。   A head block housing 3 that houses a key operation body that opens and closes the internal switch structure by opening and closing a door of a room in which an industrial machine or the like is disposed is disposed on the side surface portion 1A on the upper side of the switch housing housing 1. It is arranged.

蓋体２は、上端側に一対の係合突起２ａが形成されており、係合突起２ａをスイッチ収容筐体１の上部側の側面部１Ａの内壁に形成した係合孔１ｃにそれぞれ係合することにより、スイッチ収容筐体１の前面部１Ｂに形成した蓋体設置部１ｂに配設されるように構成している。   The lid body 2 has a pair of engaging protrusions 2a formed on the upper end side, and the engaging protrusions 2a are respectively engaged with engaging holes 1c formed on the inner wall of the side surface portion 1A on the upper side of the switch housing 1. By doing so, it is configured so as to be disposed in the lid installation portion 1b formed in the front surface portion 1B of the switch housing 1.

蓋体２の下部側には、互いに離間する状態で筐体２の前面部２Ａに面するように一対の取付け片部２ｂが形成されている。取付け片部２ｂには、それぞれ、蓋体２側の取付け孔２ｃが貫通形成されている。   A pair of attachment pieces 2b are formed on the lower side of the lid 2 so as to face the front surface 2A of the housing 2 in a state of being separated from each other. Each attachment piece 2b is formed with a through hole 2c on the lid 2 side.

蓋体２側の取付け孔２ｃに連通対向するように、スイッチ収容筐体１の蓋体設置部１ｂの下部側には、スイッチ収容筐体１側の取付け孔１ｅが一対形成されている。   A pair of mounting holes 1e on the switch housing case 1 side is formed on the lower side of the lid body setting portion 1b of the switch housing case 1 so as to communicate and oppose to the mounting hole 2c on the lid body 2 side.

そして、スイッチ収容筐体１側の取付け孔１ｅには、それぞれ、スイッチ収容筐体１の左右側の両側面部１Ｃに形成したナット部材収容凹部１Ｄが連通している（図２および図２参照）。   And the nut member accommodation recessed part 1D formed in the both-sides 1C of the right and left sides of the switch accommodation housing | casing 1 is connecting with the attachment hole 1e by the side of the switch accommodation housing | casing 1 (refer FIG. 2 and FIG. 2). .

ナット部材収容凹部１Ｄは、ナット部材５が上下方向縦向きとなって移動可能な状態で収容されるような容積を有しているも、ナット部材収容凹部１Ｄの奥壁をナット部材５の外周部が多角面形状に形成されていることに対応して凹状の多角形状面１Ｄ−１に形成しておき、ナット部材５を収容した際に回り止めが施されるようになっている。   The nut member housing recess 1D has such a volume that the nut member 5 can be housed in a vertically movable state, but the inner wall of the nut member housing recess 1D is disposed on the outer periphery of the nut member 5. Corresponding to the fact that the portion is formed in a polygonal shape, it is formed on the concave polygonal surface 1D-1 and is provided with a detent when the nut member 5 is accommodated.

ナット部材収容凹部１Ｄの上部側におけるスイッチ収容筐体１の左右側の側面部１Ｃにおいて、図４に示す熱変形用の臼４を挿入できるように、臼挿入用孔部１ｆが形成されている。   A mortar insertion hole 1f is formed in the left and right side surfaces 1C of the switch housing 1 on the upper side of the nut member housing recess 1D so that the thermal deformation mortar 4 shown in FIG. 4 can be inserted. .

臼挿入用孔部１ｆは、ナット集部材収容凹部１Ｄに連通するように形成されているとともに、臼挿入用孔部１ｆ内に配設されるように、スイッチ収容筐体１の左右側の側面部１Ｃ側には、突起１Ｅがそれぞれ外方に延在するように一体突設されており、突起１Ｅは、各ナット部材収容凹部１Ｄを臨むように構成されている。   The mortar insertion hole 1f is formed so as to communicate with the nut collecting member housing recess 1D, and is disposed on the left and right sides of the switch housing 1 so as to be disposed in the mortar insertion hole 1f. On the part 1C side, the protrusions 1E are integrally protruded so as to extend outward, and the protrusions 1E are configured to face the respective nut member accommodation recesses 1D.

かかる構成により、ナット部材５をナット部材収容凹部１Ｄ内に位置修正可能に収容するには、まず、図２および図３に示すように、ナット部材５を上下方向縦向きにした状態でナット部材収容凹部１Ｄ内に挿入しておき、この状態を保持した状態で、図４に示すように加熱された熱変形用の臼４を突起１Ｅの先端部に宛がって、突起１Ｅの先端部に押圧力をかけることによって熱変形させて圧潰し、圧潰片部１Ｆを形成する。   With this configuration, in order to accommodate the nut member 5 in the nut member accommodating recess 1D so that the position of the nut member 5 can be corrected, first, as shown in FIGS. 2 and 3, the nut member 5 is vertically oriented in the vertical direction. In the state where it is inserted into the housing recess 1D and this state is maintained, the heated mortar 4 for heat deformation is applied to the tip of the projection 1E as shown in FIG. By applying a pressing force to the plate, it is thermally deformed and crushed to form a crushed piece 1F.

この結果、圧潰片部１Ｆは、図６に示すように、ナット部材収容凹部１Ｄ側に張り出して、ナット部材５の外方表出面側を係合することになり、ナット部材５は、ナット部材収容凹部１Ｄ内において、遊嵌状態となって位置調整可能で且つ落下防止状態で構成されていることになる。   As a result, as shown in FIG. 6, the crushing piece portion 1 </ b> F projects to the nut member housing recess 1 </ b> D side and engages the outer exposed surface side of the nut member 5. In the housing recess 1D, the position is adjustable and the fall is prevented.

従って、蓋体２の上端側における一対の係合突起２ａを、スイッチ収容筐体１の上部側の側面部１Ａの内壁に形成した係合孔１ｃにそれぞれ係合することにより、スイッチ収容筐体１の前面部１Ｂに形成した蓋体設置部１ｂに配設した状態で、蓋体２側の取付け孔２ｃからビス６を挿入して、ビス６をナット部材１Ｄに到達させて螺合することにより、蓋体２をスイッチ収容筐体１に装着することができる。   Accordingly, by engaging the pair of engaging protrusions 2a on the upper end side of the lid 2 with the engaging holes 1c formed in the inner wall of the side surface portion 1A on the upper side of the switch housing 1, the switch housing The screw 6 is inserted from the mounting hole 2c on the lid 2 side in a state where the screw 6 is disposed in the lid installation portion 1b formed on the front surface portion 1B, and the screw 6 reaches the nut member 1D and is screwed together. Thus, the lid body 2 can be attached to the switch housing 1.

この際、もしもスイッチ収容筐体１側の取付け孔１ｅに対して、ナット部材５に芯ブレが生じている場合には、ナット部材５をナット部材収容凹部１Ｄ内において適宜左右或いは前後方向に位置調整することによって、ナット部材５のねじ孔部５ａがスイッチ収容筐体１側の取付け孔１ｅに連通して、ビス６を取付け孔ｅが案内して正規位置においてナット部材５に螺合することができることになる。   At this time, if the nut member 5 is wobbled with respect to the mounting hole 1e on the switch housing case 1 side, the nut member 5 is appropriately positioned in the left-right or front-back direction in the nut-member housing recess 1D. By adjusting, the screw hole portion 5a of the nut member 5 communicates with the mounting hole 1e on the switch housing 1 side, and the screw 6 is guided by the mounting hole e and screwed into the nut member 5 at the normal position. Will be able to.

なお、図１において、スイッチ収容筐体１の下部側の棚部１Ｇの略中央部には、上下方向に貫通する貫通孔１ｆが形成され、外部の接続機器に接続された接続ケーブル（いずれも不図示）を挿通させて、内部スイッチ構成体に接続可能に構成されている。   In FIG. 1, a through hole 1f penetrating in the vertical direction is formed in a substantially central portion of the shelf 1G on the lower side of the switch housing 1 and a connection cable connected to an external connection device (both (Not shown) can be inserted and connected to the internal switch structure.

以上のように構成する本発明の実施例においては、ナット部材５は、スイッチ収容筐体１に一体に形成した突起１Ｆの先端部を熱変形により圧潰することによって形成された圧潰片部１Ｆにより、ナット部材収容凹部１Ｄ内において位置調整可能に係合されることから、従来の技術における別体の覆い蓋を廃止することができ、部品点数や取付け工数を軽減することが期待でき、しかも、ナット部材収容凹部１Ｄ内においてナット部材５が適宜位置調整可能に係合設置されていることから、スイッチ収容筐体１或いは蓋体２の成形時に成形誤差等により、スイッチ収容筐体１側の取付け孔１ｅとナット部材収容凹部１Ｄ内のナット部材５との間で芯ぶれが生じたとしても、ナット部材５がナット部材収容凹部１Ｄ内を適宜位置修正されて、当該芯ぶれを解消し、常時蓋体２をスイッチ収容筐体１に確実に装着することができることになる。   In the embodiment of the present invention configured as described above, the nut member 5 is formed by the crushing piece portion 1F formed by crushing the tip portion of the protrusion 1F formed integrally with the switch housing 1 by thermal deformation. Since the nut member accommodating recess 1D is engaged so as to be position-adjustable, it is possible to eliminate a separate cover lid in the prior art, and to reduce the number of parts and mounting man-hours, Since the nut member 5 is engaged and installed in the nut member housing recess 1D so that the position of the nut member 5 can be adjusted as appropriate, mounting on the switch housing case 1 side due to molding errors or the like during molding of the switch housing case 1 or the lid 2 Even if a runout occurs between the hole 1e and the nut member 5 in the nut member accommodation recess 1D, the position of the nut member 5 is appropriately corrected in the nut member accommodation recess 1D. To eliminate runout, so that it is possible to reliably attach the constantly lid 2 to the switch housing enclosure 1.

なお、上記実施例においては、圧潰片部１Ｆは突起１Ｅを熱変形により形成するように下が、これに限定されるものではなく、例えば、プレス成形等により形成するようにしてもよい。   In the above-described embodiment, the crushing piece portion 1F is not limited to this so that the protrusion 1E is formed by thermal deformation, but may be formed by, for example, press molding or the like.

以上説明したように、本発明は、ナット部材は、スイッチ収容筐体に一体に形成した突起の先端部を熱変形等により圧潰することによって形成された圧潰片部により、ナット部材収容凹部内において位置調整可能に係合されることから、従来の技術における別体の覆い蓋を廃止することができ、部品点数や取付け工数を軽減することが期待でき、しかも、ナット部材収容凹部内においてナット部材が適宜位置調整可能に係合設置されていることから、スイッチ収容筐体或いは蓋体の成形時に成形誤差等により、スイッチ収容筐体側の取付け孔とナット部材収容凹部内におけるナット部材のねじ孔部との間で芯ぶれが生じたとしても、ナット部材がナット部材収容凹部内を適宜位置修正されて、当該芯ぶれを解消し、常時蓋体をスイッチ収容筐体に確実に装着することができることになるために、内部スイッチ構成体を収容するスイッチケース装置、特に、例えば産業機械が設置される部屋の出入口などに取付けられて、当該出入口の扉が開かれる時には当該産業機械への電源の供給を停止するようになしたドア用スイッチを構成するスイッチケース装置等に好適であるといえる。   As described above, according to the present invention, the nut member is formed in the nut member accommodating recess by the crushing piece portion formed by crushing the tip end portion of the protrusion formed integrally with the switch housing case by thermal deformation or the like. Since it is engaged so that the position can be adjusted, a separate cover in the conventional technique can be eliminated, and the number of parts and mounting man-hours can be reduced. Are fitted and installed so that the position of the switch housing can be adjusted appropriately. Due to molding errors during molding of the switch housing or lid, the screw hole of the nut member in the mounting hole on the switch housing and the nut member housing recess Even if a runout occurs between the nut member and the nut member, the position of the nut member is appropriately corrected in the nut member housing recess to eliminate the runout, and the lid is always attached to the switch housing case. When the door of the doorway is opened by being attached to a doorway of a room where an industrial machine is installed, for example, a doorway of a room where an industrial machine is installed. It can be said that the present invention is suitable for a switch case device or the like that constitutes a door switch that stops supplying power to the industrial machine.
