Description

本発明は、母線バーの上面に配置した絶縁基台に底面にプラグ端子を備えたプラグイン機器の絶縁基台への取付構造に関するものである。   The present invention relates to a structure for mounting a plug-in device having an insulating base disposed on an upper surface of a bus bar on a bottom surface and a plug terminal on the insulating base.

底面にプラグ端子を備えたプラグイン機器を絶縁基台の前面に取り付けて、前記プラグ端子を絶縁基台に設けたプラグ挿通孔を介して絶縁基台の後面側に配設した母線バーに接続するプラグイン機器の絶縁基台への取付構造は、母線バーが活線状態であっても、プラグイン機器を着脱しても母線バーが絶縁基台に覆われていることから括線作業が可能になるという利点がある。ところが、絶縁基台にプラグイン機器を取り付ける場合には、絶縁基台に貫通させたプラグ挿通孔を確認しながらプラグ端子をプラグ挿通孔に挿通したうえ該プラグ端子を母線バーと接続して取り付ける必要がある（例えば、特許文献１参照）。また、一般に、絶縁基台へのブレーカ等の機器の固定はネジ止めにより行うものであった（例えば、特許文献２参照）。
実開平６−７０４０４公開公報（図３） 特開平８−６４１０１公開公報（図１、図６（ｂ）） A plug-in device with a plug terminal on the bottom is attached to the front surface of the insulating base, and the plug terminal is connected to a bus bar arranged on the rear surface side of the insulating base through a plug insertion hole provided in the insulating base. The installation structure of the plug-in device to the insulation base is such that the bus bar is covered with the insulation base even if the bus bar is in a live state or the plug bar is attached or detached. There is an advantage that it becomes possible. However, when a plug-in device is attached to the insulating base, the plug terminal is inserted into the plug insertion hole while confirming the plug insertion hole penetrating the insulating base, and the plug terminal is connected to the bus bar and attached. There is a need (see, for example, Patent Document 1). In general, fixing of a device such as a breaker to an insulating base is performed by screwing (for example, see Patent Document 2).
Japanese Utility Model Publication No. 6-70404 (FIG. 3) Japanese Patent Laid-Open No. 8-64101 (FIGS. 1 and 6B)

しかし、このような取り付けは、作業者にとって正面からはプラグイン機器に隠れることとなる絶縁基台のプラグ挿通孔をプラグイン機器の上側方等より覗き込むように確認しながら重量のあるプラグイン機器を手で支えてプラグ端子をプラグ挿通孔に挿通したうえ該プラグ端子を母線バーに接続するものである。そのため、プラグ端子がプラグ挿通孔に対して斜めを向く場合があり、これを見逃してこの斜めの状態でプラグイン機器を押し込むとプラグ端子が母線バーに斜めに当たり変形する問題がある。また、絶縁基台へのプラグイン機器の固定をネジ止めにより行うものでは、ネジ止め作業が厄介であるという問題がある。   However, this type of attachment is difficult for the operator while checking the plug insertion hole of the insulating base that will be hidden behind the plug-in device from the front side, looking into the plug-in device from above, etc. The device is supported by hand and the plug terminal is inserted into the plug insertion hole, and the plug terminal is connected to the bus bar. For this reason, there is a case where the plug terminal is inclined obliquely with respect to the plug insertion hole, and there is a problem that when the plug-in device is pushed in without being overlooked, the plug terminal strikes the bus bar obliquely. Moreover, in the case where the plug-in device is fixed to the insulating base by screwing, there is a problem that screwing work is troublesome.

本発明は前記のような従来の問題点を解決して、プラグイン機器を絶縁基台に取り付けるときにプラグイン機器の底面に設けたプラグ端子が変形することがないうえ、絶縁基台へのプラグイン機器の固定作業が容易なプラグイン機器の絶縁基台への取付構造を提供することである。   The present invention solves the conventional problems as described above, and the plug terminal provided on the bottom surface of the plug-in device is not deformed when the plug-in device is attached to the insulating base. It is an object of the present invention to provide a structure for attaching a plug-in device to an insulating base that facilitates fixing of the plug-in device.

本発明のプラグイン機器の絶縁基台への取付構造は、底面にプラグ端子を備えたプラグイン機器を絶縁基台の前面に取り付けて、前記プラグ端子を絶縁基台に設けたプラグ挿通孔を介して絶縁基台の後面側に配設した母線バーに接続するプラグイン機器の絶縁基台への取付構造において、絶縁基台の前面にプラグイン機器の傾き防止壁を設けたことを特徴とするものを請求項１に記載の発明としたものである。   The structure for attaching the plug-in device to the insulating base of the present invention is such that a plug-in device having a plug terminal on the bottom surface is attached to the front surface of the insulating base, and a plug insertion hole provided in the insulating base is provided with the plug terminal. In the mounting structure of the plug-in device connected to the bus bar arranged on the rear surface side of the insulating base via the insulating base, the tilt prevention wall of the plug-in device is provided on the front surface of the insulating base. What is to be done is the invention according to claim 1.

そして、この請求項１に記載の発明において、傾き防止壁をプラグイン機器の下方外形全体に対応させて設けたものを請求項２に記載の発明とする。また、これら請求項１又２に記載の発明において、プラグイン機器を絶縁基台にヒンジ構造の係止具により着脱自在に取り付けたものを請求項３に記載の発明とし、さらに、この請求項３に記載の発明において、ヒンジ構造の係止具を、絶縁基台に設けた係止具取付孔の孔縁に設けた軸受部に軸部をもって中間部を軸支する幅広板状の係止具本体の上端にプラグイン機器の側面に突設した係止部に係止する上部係止爪を設け、また、該係止具本体の下端に係止具取付孔の孔縁下端に係止する下部係止爪を設けたものとしたものを請求項４に記載の発明とする。   And in this invention of Claim 1, what provided the inclination prevention wall corresponding to the whole lower external shape of a plug-in apparatus is set as invention of Claim 2. The invention according to claim 1 or 2 is the invention according to claim 3, wherein the plug-in device is detachably attached to the insulating base with a hinge-type locking tool. 3. The invention according to claim 3, wherein the hinged locking device is a wide plate-shaped locking device having a shaft portion on a bearing portion provided at a hole edge of a locking device mounting hole provided in an insulating base and pivotally supporting an intermediate portion. An upper locking claw is provided at the upper end of the fixture main body to be engaged with the locking portion protruding from the side of the plug-in device, and the lower end of the locking fixture main body is locked to the lower end of the hole edge of the locking fixture mounting hole. The invention according to claim 4 is provided with a lower locking claw.

前記した請求項１に記載のプラグイン機器の絶縁基台への取付構造は、絶縁基台の前面にプラグイン機器の傾き防止壁を設けたものであるから、プラグイン機器を絶縁基台に取り付けるときに、作業者がプラグイン機器の底面に備えたプラグ端子をプラグ挿通孔と一致させたうえ、プラグ端子をプラグ挿通孔に挿通してプラグ端子を母線バーに接続するためプラグイン機器を押し込めば、プラグ端子がプラグ挿通孔に対して斜めを向いた場合には、プラグイン機器も傾いていることなのでプラグイン機器自体が傾き防止壁により押圧が阻害されることとなる。そこで、プラグイン機器を傾き防止壁に添うように垂直に補正すればプラグ端子が母線バーに対して垂直方向を向き斜め方向の力を受けて変形することなく接続できるものである。   Since the structure for attaching the plug-in device to the insulating base according to claim 1 is provided with an anti-tilt wall of the plug-in device on the front surface of the insulating base, the plug-in device is used as the insulating base. When installing, plug the plug-in device to connect the plug terminal to the bus bar by inserting the plug terminal into the plug insertion hole after aligning the plug terminal on the bottom of the plug-in device with the plug insertion hole. When the plug terminal is pushed in, when the plug terminal is inclined with respect to the plug insertion hole, the plug-in device is also inclined, so that the plug-in device itself is inhibited from being pressed by the inclination prevention wall. Therefore, if the plug-in device is corrected vertically so as to follow the tilt prevention wall, the plug terminal can be connected without being deformed by receiving a force in an oblique direction with respect to the bus bar.

また、請求項２の発明のように、傾き防止壁をプラグイン機器の底面全外周に対応させて設けたものとすると、プラグイン機器の取付位置の目安となり絶縁基台への取り付けも容易となり、また、取り付け時にプラグイン機器を仮保持するものでもある。また、請求項３の発明にあっては、プラグイン機器を絶縁基台にヒンジ構造の係止具より着脱自在に取り付けたものであるから、プラグイン機器の絶縁基台への着脱は係止具を起伏させるだけで容易に行うことができるものである。   Further, if the anti-tilt wall is provided so as to correspond to the entire outer periphery of the bottom surface of the plug-in device as in the invention of claim 2, it becomes an indication of the mounting position of the plug-in device and can be easily attached to the insulating base. Also, the plug-in device is temporarily held at the time of attachment. Further, in the invention of claim 3, since the plug-in device is detachably attached to the insulating base from the hinge-structure locking tool, the plug-in device is not attached to or detached from the insulating base. It can be easily performed by simply raising and lowering the tool.

さらに、請求項４の発明にあっては、ヒンジ構造の係止具を、ヒンジ構造の係止具を、絶縁基台に設けた係止具取付孔の孔縁に設けた軸受部に軸部をもって中間部を軸支する幅広板状の係止具本体の上端にプラグイン機器の側面に突設した係止部に係止する上部係止爪を設け、また、該係止具本体の下端に係止具取付孔の孔縁下端に係止する下部係止爪を設けたものとしたので、絶縁基台へのプラグイン機器の固定は上部係止爪のプラグイン機器への係止と下部係止爪の絶縁基台に設けた係止具取付孔との係止により行われるので係止時に係止具本体の軸部に力が加わり破損する虞が無いものである。   Furthermore, in the invention of claim 4, the hinge structure is provided with the hinge structure, and the hinge structure is provided on the bearing portion provided at the hole edge of the engagement tool mounting hole provided in the insulating base. An upper locking claw for locking to a locking portion protruding from the side surface of the plug-in device is provided at the upper end of the wide plate-shaped locking device main body that pivotally supports the intermediate portion, and the lower end of the locking device main body Since the lower locking claw that locks to the bottom edge of the hole of the locking tool mounting hole is provided, the fixing of the plug-in device to the insulating base is the same as the locking of the upper locking claw to the plug-in device. Since it is carried out by locking with the locking tool mounting hole provided in the insulating base of the lower locking claw, there is no possibility that the shaft part of the locking tool main body is applied with force and damaged at the time of locking.

次に、本発明の好ましい実施の形態を図に基づき説明する。
〔第１の実施形態〕
先ず、第１の実施形態を図１〜図７に示す分岐用ブレーカを設置した小型の筐体を組み合わせたユニットタイプの分電盤に使用するプラグイン機器の絶縁基台への取付構造により説明する。
１はプラグイン機器２を前面に取り付けるための板状の絶縁基台１１と該絶縁基台１１の前面を覆う逆箱状の蓋部１２と絶縁基台１１の背面側に母線バー３を配置するための浅箱状の幹線バーケース１３を設けた筐体である。 Next, a preferred embodiment of the present invention will be described with reference to the drawings.
[First Embodiment]
First, the first embodiment will be described with reference to a structure for attaching a plug-in device to an insulating base used in a unit type distribution board combined with a small-sized casing provided with a branch breaker shown in FIGS. .
Reference numeral 1 denotes a plate-like insulating base 11 for attaching the plug-in device 2 to the front surface, an inverted box-shaped lid portion 12 covering the front surface of the insulating base 11, and a bus bar 3 on the back side of the insulating base 11. It is the housing | casing which provided the shallow box-shaped main bar case 13 for doing.

前記プラグイン機器２は底面２１に差込式のプラグ端子２２を３本の母線バー３に対応して備えたものである。なお、図示のプラグイン機器２は、底面２１に差込式のプラグ端子２２を備えたプラグインアダプタ２ａにネジ端子式のブレーカ２ｂを搭載してプラグ端子２２とブレーカ２ｂの電源側ネジ端子とをプラグインアダプタ２ａに埋め込んだ導電バーにより接続したものであるが、底面に直接負荷側のプラグ端子２２を備えたブレーカであっても良い。   The plug-in device 2 has plug-type plug terminals 22 on the bottom surface 21 corresponding to the three bus bars 3. In the illustrated plug-in device 2, a screw terminal type breaker 2b is mounted on a plug-in adapter 2a having a plug-type plug terminal 22 on the bottom surface 21, and the plug terminal 22 and the power supply side screw terminal of the breaker 2b are connected to each other. Are connected by a conductive bar embedded in the plug-in adapter 2a, but a breaker having a load-side plug terminal 22 directly on the bottom surface may be used.

そして、プラグイン機器２は図３、図４に示すように絶縁基台１１の前面に、前記プラグ端子２２を該絶縁基台１に設けた孔内面を傾斜案内面に形成したプラグ挿通孔１１ａを介して絶縁基台１１の後面側に配設した母線バー３に設けたクリップ式の端子受部３２に嵌合して接続させて取り付けるものである。   As shown in FIGS. 3 and 4, the plug-in device 2 has a plug insertion hole 11a in which a hole inner surface provided with the plug terminal 22 in the insulating base 1 is formed as an inclined guide surface on the front surface of the insulating base 11. Are fitted and connected to a clip-type terminal receiving portion 32 provided on the bus bar 3 disposed on the rear surface side of the insulating base 11.

また、前記絶縁基台１１の前面にプラグイン機器２を取付時に傾きを防止するための傾き防止壁４を設けている。この傾き防止壁４は絶縁基台１１の前面に形成したプラグイン機器２の底面と同大の取付面１１１の周縁を高くして該周縁内面により形成している。また、取付面１１１の全周縁を高くしてプラグイン機器２の下方外形全体に対応させて設けてもよい。   Further, a tilt prevention wall 4 is provided on the front surface of the insulating base 11 to prevent tilting when the plug-in device 2 is mounted. The inclination prevention wall 4 is formed by the peripheral inner surface with the peripheral edge of the mounting surface 111 having the same size as the bottom surface of the plug-in device 2 formed on the front surface of the insulating base 11 being raised. Alternatively, the entire peripheral edge of the mounting surface 111 may be raised so as to correspond to the entire lower outer shape of the plug-in device 2.

５はプラグイン機器２を絶縁基台１１に着脱自在に取り付けるためのヒンジ構造の係止具である。このヒンジ構造の係止具５は、絶縁基台１１に設けた係止具取付孔１１ｂの孔縁に設けた軸受部に軸部５１をもって中間部を軸支する幅広板状の係止具本体５０の上端にプラグイン機器２の側面に突設して係止部２ｃに係止する上部係止爪５２を設け、また、該係止具本体５０の下端に係止具取付孔１１ｂの孔縁下端に係止する下部係止爪５３を上部係止爪５２とは逆向きに設けたものである。   Reference numeral 5 denotes a hinge-type locking tool for detachably attaching the plug-in device 2 to the insulating base 11. This hinge-structured locking tool 5 is a wide plate-shaped locking tool body that pivotally supports an intermediate portion with a shaft portion 51 on a bearing portion provided at a hole edge of a locking tool mounting hole 11b provided in an insulating base 11. An upper latching claw 52 is provided at the upper end of the plug-in device 2 so as to protrude from the side surface of the plug-in device 2 and is latched to the latching portion 2c. A lower locking claw 53 that locks to the lower edge of the edge is provided in the direction opposite to the upper locking claw 52.

このように構成されたものは、絶縁基台１１の前面にプラグイン機器２の傾き防止壁４を設けたものであるから、プラグイン機器２を絶縁基台に取り付けるときに、作業者がプラグイン機器２の底面２１に備えた差込式のプラグ端子２２をプラグ挿通孔１１ａと一致させたうえ、プラグ端子２２をプラグ挿通孔１１ａに挿通してプラグ端子２１を母線バー３に接続するためにプラグイン機器２を押し込めば、プラグ端子２２がプラグ挿通孔１１ａに対して斜めを向いた場合には、プラグイン機器２も傾斜しているのでプラグイン機器２自体が傾き防止壁４により押圧を阻害されることとなりプラグ端子２１の挿入動作も停止する。そこで、プラグイン機器２を傾き防止壁４に添うように垂直に補正すればプラグ端子２２が母線バー３に対して垂直方向を向き斜め方向から力が加わることがなく変形せずに母線バー３に設けクリップ式の端子受部３２に嵌合して接続できるものである。なお、プラグイン機器２の底面２１に備えるプラグ端子２２をクリップ式の端子受部に形成して母線バー３の接続部を板状体のままに形成してこれがクリップ式の端子受部に挟持されるものとしてもよい。   In this configuration, the tilt prevention wall 4 of the plug-in device 2 is provided on the front surface of the insulating base 11, so that when the plug-in device 2 is attached to the insulating base, the operator plugs in the plug. In order to connect the plug terminal 21 to the bus bar 3 by inserting the plug terminal 22 into the plug insertion hole 11a after aligning the plug-type plug terminal 22 provided on the bottom surface 21 of the in-device 2 with the plug insertion hole 11a. If the plug-in device 2 is pushed in, the plug-in device 2 itself is pressed by the anti-tilt wall 4 because the plug-in device 2 is also inclined when the plug terminal 22 is inclined with respect to the plug insertion hole 11a. The plug terminal 21 insertion operation is also stopped. Therefore, if the plug-in device 2 is corrected vertically so as to follow the anti-tilt wall 4, the plug terminal 22 faces the bus bar 3 in the vertical direction and no force is applied from an oblique direction, and the bus bar 3 is not deformed. It can be connected to the clip-type terminal receiving portion 32 by being fitted to the connector. In addition, the plug terminal 22 provided on the bottom surface 21 of the plug-in device 2 is formed in the clip-type terminal receiving portion, and the connection portion of the bus bar 3 is formed as a plate-like body, and this is sandwiched by the clip-type terminal receiving portion. It is good also as what is done.

また、傾き防止壁４をプラグイン機器２の底面全外周に対応させて設けたものとするとことにより、プラグイン機器２の取付位置の目安となり絶縁基台１１への取り付けも容易となり、また、取り付け時にプラグイン機器２の底面側が仮保持されるのでその後の係止具５による絶縁基台１１への固定作業も容易なものである。   Further, by providing the anti-tilt wall 4 so as to correspond to the entire outer periphery of the bottom surface of the plug-in device 2, it becomes an indication of the mounting position of the plug-in device 2 and can be easily attached to the insulating base 11. Since the bottom surface side of the plug-in device 2 is temporarily held at the time of attachment, the subsequent fixing work to the insulating base 11 by the locking tool 5 is also easy.

さらに、プラグイン機器２を絶縁基台１１にヒンジ構造の係止具５より着脱自在に取り付けするものであるから、プラグイン機器２の絶縁基台１１への着脱は係止具５を起伏させるだけで容易に行うことができるものである。また、ヒンジ構造の係止具５を、絶縁基台１１に設けた係止具取付孔１１ｂの孔縁に設けた軸受部に軸部５１をもって中間部を軸支する幅広板状の係止具本体５０の上端にプラグイン機器２の側面に突設して係止部２ｃに係止する上部係止爪５２を設け、また、該係止具本体５０の下端に係止具取付孔１１ｂの孔縁下端に係止する下部係止爪５３を上部係止爪５２とは逆向きに設けたものとすれば、絶縁基台１１へのプラグイン機器２の固定は上部係止爪６２のプラグイン機器への係止と下部係止爪５３の絶縁基台１１に設けた係止具取付孔１１ｂとの係止により行われるので係止時に係止具本体５０の軸部５１に力が加わり破損する虞が無いものである。   Furthermore, since the plug-in device 2 is detachably attached to the insulating base 11 from the hinge-structured locking tool 5, the plug-in equipment 2 is attached to and detached from the insulating base 11 to undulate the locking tool 5. It can be done easily with just that. In addition, the locking member 5 having a hinge structure has a wide plate-like locking tool that pivotally supports the intermediate portion with the shaft portion 51 on the bearing portion provided at the hole edge of the locking device mounting hole 11b provided in the insulating base 11. An upper locking claw 52 is provided at the upper end of the main body 50 so as to protrude from the side surface of the plug-in device 2 and is locked to the locking portion 2c, and the locking tool mounting hole 11b is provided at the lower end of the locking tool main body 50. If the lower locking claw 53 that locks to the lower end of the hole edge is provided opposite to the upper locking claw 52, the plug-in device 2 is fixed to the insulating base 11 by plugging the upper locking claw 62. Since the locking is performed by the locking to the in-device and the locking tool mounting hole 11b provided in the insulating base 11 of the lower locking claw 53, a force is applied to the shaft portion 51 of the locking tool body 50 during locking. There is no risk of breakage.

〔第２の実施形態〕
続いて、第２の実施形態を図８〜図９に示す分岐用ブレーカを多数配設した分電盤に使用するプラグイン機器の絶縁基台への取付構造により説明する。
１は分電盤の筐体であり、該筐体１の背面には垂直に母線バー３が３本平行に設けられている。この母線バー３を覆うように多数の板状の絶縁基台１１が母線バー３の両側に設けた取付レール部９に取り付けられている。前記各絶縁基台１１には第1の実施形態と同様にプラグイン機器２を前面に取り付けて、絶縁基台１１の背面側に配置されていることとなる母線バー３に、プラグイン機器２の底面２１に設けた差込式のプラグ端子２２を絶縁基台１に設けたプラグ挿通孔１１ａを介して母線バー３に接続させるものである。また、絶縁基台１１は複数のプラグイン機器２を取付できる大きさのものであってもよい。 [Second Embodiment]

Reference numeral 1 denotes a casing of a distribution board, and three bus bars 3 are provided in parallel on the back surface of the casing 1 in parallel. A large number of plate-like insulating bases 11 are attached to mounting rail portions 9 provided on both sides of the bus bar 3 so as to cover the bus bar 3. Similarly to the first embodiment, the plug-in device 2 is attached to the front surface of each of the insulating bases 11, and the plug-in device 2 is connected to the bus bar 3 that is disposed on the back side of the insulating base 11. The plug-type plug terminal 22 provided on the bottom surface 21 is connected to the bus bar 3 through the plug insertion hole 11 a provided in the insulating base 1. The insulating base 11 may be of a size that allows a plurality of plug-in devices 2 to be attached.

なお、この第２の実施形態は筐体１が第1の実施形態と相違するものであるが、絶縁基台１１、プラグイン機器２、プラグ端子２２、母線バー３、傾き防止壁４及びヒンジ構造の係止具の構成及び作用効果は第１の実施形態と同一であるので、第１の実施形態における説明、図面を援用しては説明は省略する。   In the second embodiment, the housing 1 is different from the first embodiment, but the insulating base 11, the plug-in device 2, the plug terminal 22, the bus bar 3, the tilt prevention wall 4, and the hinge Since the structure and the function and effect of the locking device having the structure are the same as those of the first embodiment, the description and the drawings in the first embodiment are used and the description thereof is omitted.
