Description

本発明は、内機の固定構造に関するものである。   The present invention relates to an internal unit fixing structure.

従来の内機の固定構造として、主幹部分と分岐部分の内機それぞれの四隅を固定ネジ等によって固定する方法がある。   As a conventional internal unit fixing structure, there is a method in which the four corners of the main unit and the branch unit are fixed with fixing screws or the like.

しかし、主幹部分と分岐部分の内機をそれぞれ固定していたため作業工程数が多く、固定ネジ等によるコストも発生するという欠点があった。   However, since the main unit and the branch unit are respectively fixed, the number of work steps is large, and there is a disadvantage that costs due to fixing screws and the like are also generated.

この改善策として、図６に記載の特許文献１のように主幹部分と分岐部分のそれぞれの内機５１の一部を重ね、片方の内機５１によって他方の内機５１を押さえて固定することによって作業工程数と固定金具５７のコストを削減する方法がある。   As an improvement measure, as in Patent Document 1 described in FIG. 6, a part of each of the main unit 51 and the branch unit 51 is overlapped, and the other internal unit 51 is pressed and fixed by one internal unit 51. Thus, there is a method of reducing the number of work steps and the cost of the fixing bracket 57.

又、機器を内機に固定する方法としては、図７に記載の特許文献２のように内機６１の機器６８取り付け位置近傍には切欠部９６を設け、切欠部９６には機器保持部材６３をはめ込み、この機器保持部材６３の構造は、切欠部９６に嵌合可能な嵌合部と、機器６８を固定する凹部６０とを形成し、凹部６０を機器６８の負荷側接続端子を有する面に設けられた凸部６９にはめ込み、機器６８を内機６１に固定する方法がある。
特開２００７−３１２５６１ 特開２００２−６４９１１ Further, as a method of fixing the device to the internal unit, a notch 96 is provided in the vicinity of the mounting position of the device 68 of the internal unit 61 as in Patent Document 2 shown in FIG. 7, and the device holding member 63 is provided in the notch 96. The device holding member 63 has a structure in which a fitting portion that can be fitted into the notch 96 and a recess 60 that fixes the device 68 are formed, and the recess 60 has a load side connection terminal of the device 68. There is a method of fixing the device 68 to the internal unit 61 by fitting into the convex portion 69 provided in the inner device 61.

しかし、特許文献１に記載の発明では、主幹部分と分岐部分の内機の一部を重ね、片方の内機によって他方の内機を押さえて固定するため、分岐回路の回路数が増えると、内機を固定する固定ネジ等の位置が離れる。このため、輸送時の荷降ろし等による衝撃が加わると内機が湾曲し、弾みにより分電盤本体カバー等の破損の原因となるという欠点がある。   However, in the invention described in Patent Document 1, since a part of the main unit and the internal unit of the branch part are overlapped and the other internal unit is pressed and fixed by one internal unit, when the number of branch circuits increases, The position of the fixing screw etc. that fixes the inner machine is separated. For this reason, when an impact due to unloading or the like during transportation is applied, the internal unit is bent, and there is a drawback in that the distribution board main body cover or the like is damaged due to the spring.

又、特許文献１に記載の発明では、分岐回路の回路数が増えた際に内機を分割してそれぞれを固定することによって荷降ろし等による衝撃から内機の湾曲を防ぐ方法も考えられるが、部品数や作業工程数が増えるという欠点がある。   Moreover, in the invention described in Patent Document 1, there is a method of preventing the bending of the internal unit from an impact caused by unloading or the like by dividing the internal unit and fixing each when the number of branch circuits increases. There is a disadvantage that the number of parts and the number of work processes increase.

又、特許文献２に記載の発明では、内機に取り付けられる機器のみの固定であって内機は固定されないため、輸送時の荷降ろし等による衝撃が加わると内機が湾曲し、弾みにより分電盤本体カバー等の破損の原因となることを防ぐことができないという欠点がある。   Further, in the invention described in Patent Document 2, since only the device attached to the internal unit is fixed, and the internal unit is not fixed, the internal unit is bent when an impact due to unloading or the like during transportation is applied, and it is separated by the bounce. There is a drawback that it cannot prevent the cover of the electrical panel body from being damaged.

又、特許文献２に記載の発明では、別の発明との組合わせによって内機を固定する方法が考えられるが、部品数や作業工程数が増えるという欠点がある。   In the invention described in Patent Document 2, a method of fixing the internal unit by combining with another invention is conceivable, but there is a disadvantage that the number of parts and the number of work processes increase.

このため、本発明によって解決しようとする課題は、輸送時の荷降ろし等の衝撃による内機の湾曲を防ぎ、弾みにより分電盤本体カバー等が破損する恐れを少なくする内機の固定構造を少ない部品数、作業工程数で提供することにある。   For this reason, the problem to be solved by the present invention is to provide a structure for fixing the internal unit that prevents the internal unit from being bent due to an impact such as unloading during transportation and reduces the risk of damage to the distribution board body cover and the like due to bounce. The purpose is to provide a small number of parts and work processes.

上記した課題を解決するためになされた本発明の内機固定構造は、箱体本体内部の背面に固定される分電盤の内機であって、この内機には機器保持部材と機器が設けられ、機器保持部材の上方には機器に設けられた係止部に対する被係止部を具備し、下方には箱体本体に配置されたレール部に設けられた突起部に対する掛かり部を具備するとともに、機器の取付位置付近に設けられる切欠部に嵌め込まれ、機器に設けられた係止部に被係止部を嵌め込むことで機器を固定し、レール部は内機との間の任意の位置に単数、または複数設けられるとともに突起部が掛かり部に嵌め込まれることで内機を固定するものである。 The internal unit fixing structure of the present invention made to solve the above-mentioned problem is an internal unit of a distribution board fixed to the back inside the box body, and the internal unit includes an apparatus holding member and an apparatus. Provided above the device holding member is provided with a locked portion for a locking portion provided on the device, and below is provided with a hook portion for a protrusion provided on a rail portion disposed on the box body. In addition, it is fitted into a notch provided near the mounting position of the device, and the device is fixed by fitting the locked portion into the locking portion provided in the device, and the rail portion is optional between the internal unit The internal unit is fixed by providing a single or plural parts at the position and inserting the protrusions into the hooks.

本発明の内機固定構造によれば、機器保持部材の掛かり部がレール部の突起部に引っ掛かる構造であるため、輸送時の荷降ろし等の衝撃による内機の湾曲を防ぎ、弾みにより分電盤本体カバー等が破損する恐れを少なくできる。   According to the internal machine fixing structure of the present invention, since the hanging part of the device holding member is hooked on the protruding part of the rail part, it is possible to prevent the internal machine from being bent due to an impact such as unloading during transportation, and to distribute the power by the bounce. The risk of damage to the panel cover etc. can be reduced.

又、荷降ろし等の衝撃によって内機が沈んだ場合、レール部によって内機が支えられるため沈みを防ぎ、分電盤本体カバー等が破損する恐れを少なくできる。   Further, when the internal unit sinks due to an impact such as unloading, the internal unit is supported by the rail portion, so that the sink can be prevented and the risk of damaging the distribution board body cover and the like can be reduced.

又、箱体本体に取り付ける構造であるため分岐回路数に合わせて取付数を変えることが可能であり、取付位置も変えることが可能である。   In addition, since the structure is attached to the box body, the number of attachments can be changed according to the number of branch circuits, and the attachment position can also be changed.

又、機器保持部材によって、内機に取り付けられる機器の固定と箱体本体に取り付けられる内機の固定を共に行うため、荷降ろし等の衝撃による内機の湾曲を防ぎ、弾みにより分電盤本体カバー等が破損する恐れを少ない部品で可能にした。   In addition, the equipment holding member fixes both the equipment attached to the internal machine and the internal machine attached to the box body, preventing the internal machine from being bent due to impacts such as unloading, and the distribution board body by bounce The possibility of breakage of the cover etc. is made possible with few parts.

本発明では、少ない部品数で内機の湾曲を防ぎ、分電盤本体カバー等が破損する恐れを少なくした。   In the present invention, the bending of the internal unit is prevented with a small number of parts, and the risk of breakage of the distribution board body cover and the like is reduced.

以下、本発明の実施の形態を説明する。
