Description

この発明は、電気を制御等するための電気部品と、その電気部品を収納するため鋼板等で作られた箱や、支柱に板を張り付けて覆った物などのケースで構成された盤に関するものである。   The present invention relates to an electrical component for controlling electricity, a board made of a steel plate or the like for housing the electrical component, or a board made up of a case such as an object covered with a plate attached to a column. It is.

盤は、配電システム上、電線をケースの電線挿通部に貫通させて内部の電気部品と接続される。電気部品と電線とは、圧着端子など接続具を用いて接続される。   On the power distribution system, the board is connected to the internal electrical components by passing the electric wire through the electric wire insertion portion of the case. The electrical component and the electric wire are connected using a connection tool such as a crimp terminal.

従来、盤の設置現場において、図１４に示すようにケース１００の側壁に孔１０１を加工し、孔１０１に電線１０２を軸方向に貫通させていた（例えば特許文献１参照）。また孔１０１に貫通した電線１０２の端部に接続具を接続するが、一旦接続具を接続すると、接続具は孔１０１より大きいため、電線１０２を孔１０１から抜くことができない。１０３は蓋体である。
特開２０００−１２５４２２号公報 Conventionally, at the installation site of the board, as shown in FIG. 14, a hole 101 is processed in the side wall of the case 100, and the electric wire 102 is penetrated in the hole 101 in the axial direction (see, for example, Patent Document 1). In addition, a connecting tool is connected to the end of the electric wire 102 penetrating through the hole 101. Once the connecting tool is connected, the connecting tool is larger than the hole 101, and thus the electric wire 102 cannot be pulled out of the hole 101. Reference numeral 103 denotes a lid.
JP 2000-125422 A

しかし、電線は太く曲げにくい場合が多く、また電線を孔に通してケース内という狭い場所で電線の端部に接続具を接続する必要がある。また、接続具を接続した後に電線を孔から外す必要が生じた場合、接続具を電線から外す必要があった。そのため、設置現場で電線をケースの側壁の孔に挿通して電気部品に接続するという一連の作業は容易でないという課題があった。   However, the electric wire is often thick and difficult to bend, and it is necessary to connect the connector to the end of the electric wire in a narrow place such as in the case by passing the electric wire through the hole. Moreover, when it became necessary to remove an electric wire from a hole after connecting a connector, it was necessary to remove a connector from an electric wire. For this reason, there has been a problem that a series of operations in which the electric wire is inserted into the hole in the side wall of the case and connected to the electrical component at the installation site is not easy.

したがって、この発明の目的は、電線を曲げて孔に通す作業を省くことができ、電線を容易に電線挿通部に挿通することができる盤を提供することである。   Accordingly, an object of the present invention is to provide a board that can omit the work of bending an electric wire and passing it through a hole, and can easily insert the electric wire into the electric wire insertion portion.

この発明の盤は、前面に開口を有する箱形であって周壁または底壁に電線挿通部を形成したケースと、このケース内に収納されて前記電線挿通部に挿通された断面長円形のＶＶＦケーブルの電線に接続される電気部品と、前記開口を塞ぐ蓋体とを備え、
前記電線挿通部は前記電線を挿通する穴部と、前記穴部と前記ケースの開口縁との間を連通して前記電線を前記穴部に挿入させる挿入部とを有し、前記穴部は前記電線の前記断面長円形と略相似形状でその長手方向が前記開口縁に沿う方向であり、前記挿入部は前記穴部の一端に設けられて前記挿入部と前記穴部とがＬ字形状をなしかつ前記挿入部が前記電線の前記断面長円形の長手方向の幅よりも小さく短手方向の幅よりも大きい幅を有し、
前記蓋体が前記ケースの開口縁に取付けられる扉枠と、前記扉枠に回動自在に取付けられた扉とからなり、前記扉枠で前記挿入部を閉じている。 The board of the present invention has a box shape having an opening on the front surface and a wire insertion portion formed on the peripheral wall or bottom wall, and a VVF having an oval cross section housed in the case and inserted into the wire insertion portion. An electrical component connected to the cable wire, and a lid for closing the opening;
The wire insertion portion has a hole portion for inserting the electric wire, and an insertion portion for communicating between the hole portion and the opening edge of the case to insert the electric wire into the hole portion, The electric wire is substantially similar in shape to the cross-sectional oval shape, and its longitudinal direction is a direction along the opening edge. The insertion portion is provided at one end of the hole portion, and the insertion portion and the hole portion are L-shaped. none and have a said oval cross section in the longitudinal direction of greater width than smaller lateral width than the width of the insertion portion is the electric wire,
The lid includes a door frame attached to the opening edge of the case and a door rotatably attached to the door frame, and the insertion portion is closed by the door frame.

上記構成において、前記ケースの開口縁に凹部を形成し、前記凹部に電線クリップ部を取付け、前記電線挿通部は前記電線クリップ部に形成されている。   The said structure WHEREIN: A recessed part is formed in the opening edge of the said case, an electric wire clip part is attached to the said recessed part, and the said electric wire insertion part is formed in the said electric wire clip part.

この発明の盤によれば、電線挿通部の挿入部より電線を径方向に挿入し穴部に通すことにより電線をケースに挿通させるため、従来のように電線を曲げる作業が不要となり、簡単に穴部に挿通させることができる。また電線が断面長円形であり、その短手方向の幅は挿入部の幅より小さく長手方向の幅が挿入部の幅より大きいが、穴部は電線の断面形状に相似でその長手方向が開口縁に沿う方向であるため、電線を挿入部から穴部に径方向に挿入する場合、電線をその断面長円形の長手方向に挿入し穴部で直角な方向に回転することになる。この場合、穴部に挿入した電線は挿入部から抜くことは可能であるが、摩擦係止のため自然に滑り出ることは困難である。そのため、抜け防止のためのブッシングも必要でない。 According to the board of the present invention, the wire is inserted into the case by inserting the wire in the radial direction from the insertion portion of the wire insertion portion and passing through the hole portion. It can be inserted through the hole. Also, the electric wire has an oval cross section, the width in the short direction is smaller than the width of the insertion portion, and the width in the longitudinal direction is larger than the width of the insertion portion. Since the direction is along the edge, when the electric wire is inserted from the insertion portion into the hole portion in the radial direction, the electric wire is inserted in the longitudinal direction of the oval cross section and rotated in a direction perpendicular to the hole portion. In this case, the electric wire inserted into the hole can be pulled out from the insertion portion, but it is difficult to slip out naturally due to frictional locking. For this reason, a bushing for preventing omission is not necessary.

電線クリップ部に電線挿通部を設けると、樹脂成形により電線クリップを形成することができるので、電線挿通部をケースに形成する場合と比較して製造容易になる。   Providing the electric wire insertion part in the electric wire clip part makes it possible to form the electric wire clip by resin molding, so that the manufacture becomes easier as compared with the case where the electric wire insertion part is formed in the case.

この発明の第１の実施の形態を図１から図８により説明する。図１は盤に電線を挿通した状態の外観を示している。盤のケース１は底壁６と周壁７を有する箱形であり、その開口を蓋体２で閉じている。蓋体２はケース１の開口縁に取付けられる扉枠３と、扉枠３に回動自在に取付けられた扉４とからなり、扉４を開閉することによってケース１の内部を点検等することができる。電線挿通部５ａ、５ｂは、周壁７に形成されている。電線挿通部５ａ、５ｂは切欠き穴であり、電線を挿通する穴部８ａ、８ｂと、穴部８ａ、８ｂとケース１の開口縁との間を連通して電線を穴部８ａ、８ｂに向けて径方向に挿入させる挿入部９ａ、９ｂとを有する。穴部８ａは丸穴であり、挿入部９ａは穴部８ａの径よりも小さい幅であるが、電線が挿入部９ａに挿入可能な幅を有する。また、穴部８ａには電線を挿通するブッシング１０を設けている。このブッシング１０は電線が挿通される孔部１０ｂを有し、穴部８ａの縁部に嵌合する外周部を有する。   A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the external appearance of a state where an electric wire is inserted through the board. The case 1 of the board has a box shape having a bottom wall 6 and a peripheral wall 7, and its opening is closed by a lid 2. The lid 2 includes a door frame 3 attached to the opening edge of the case 1 and a door 4 rotatably attached to the door frame 3, and the inside of the case 1 is inspected by opening and closing the door 4. Can do. The electric wire insertion portions 5 a and 5 b are formed on the peripheral wall 7. The wire insertion portions 5a and 5b are notched holes, and the wires 8a and 8b through which the wires are inserted are communicated with the holes 8a and 8b and the opening edge of the case 1 to connect the wires to the holes 8a and 8b. It has insertion parts 9a and 9b to be inserted in the radial direction. The hole portion 8a is a round hole, and the insertion portion 9a has a width smaller than the diameter of the hole portion 8a, but has a width that allows the electric wire to be inserted into the insertion portion 9a. Further, a bushing 10 through which an electric wire is inserted is provided in the hole 8a. This bushing 10 has a hole 10b through which an electric wire is inserted, and has an outer peripheral portion that fits into an edge of the hole 8a.

電線挿通部５ｂは、電線クリップ部１３に形成されている。   The wire insertion part 5 b is formed in the wire clip part 13.

図２はケース１から蓋体２を外し、電線クリップ部１３を分離した状態である。電線クリップ部１３は、ケース１の両側の周壁７の上端に形成した凹部１４に取付けられている。凹部１４はケース１の側壁の上端を内側に折り曲げた折り曲げ片１６により形成している。電線クリップ部１３は例えばアングルを用い、その一片を折り曲げ片１６に重ねて取付手段として例えばねじ１５により取付けている。一方の凹部１４は電線挿通部５ａの近傍に形成されている。電線クリップ部１３の他片に電線挿通部５ｂが複数形成されている。   FIG. 2 shows a state where the lid 2 is removed from the case 1 and the electric wire clip portion 13 is separated. The electric wire clip portion 13 is attached to a recess 14 formed at the upper end of the peripheral wall 7 on both sides of the case 1. The concave portion 14 is formed by a bent piece 16 in which the upper end of the side wall of the case 1 is bent inward. For example, an angle is used for the electric wire clip portion 13, and one piece of the electric wire clip portion 13 is overlapped with the bent piece 16 and attached with, for example, a screw 15 as attachment means. One recess 14 is formed in the vicinity of the wire insertion portion 5a. A plurality of wire insertion portions 5 b are formed in the other piece of the wire clip portion 13.

図３は蓋体２を外した状態の平面図、図４は図３のＡ−Ａ′線概略断面図である。ケース１内には複数の電気部品１７からなる内器が配置されている。電線挿通部５ａ、５ｂに挿通された電線１８、１９は内器の接続部に接続具例えば圧着端子などで接続されている。 FIG. 3 is a plan view with the lid 2 removed, and FIG. 4 is a schematic cross-sectional view taken along the line AA ′ of FIG. An internal unit made up of a plurality of electrical components 17 is disposed in the case 1. The electric wires 18 and 19 inserted through the electric wire insertion portions 5a and 5b are connected to the connection portion of the internal unit by a connecting tool such as a crimp terminal.

図５は電線挿通部５ｂに電線１９を挿通した状態の詳細を示している。図６はその平面図である。電線挿通部５ｂは、上記したように電線１９を挿通する穴部８ｂと、穴部８ｂよりも小さい幅で、穴部８ｂとケース１の開口縁との間を連通する挿入部９ｂを有し、図５に示すように、挿入部９ｂの位置が穴部８ｂの一端に形成されている。 FIG. 5 shows details of a state where the electric wire 19 is inserted into the electric wire insertion portion 5b. FIG. 6 is a plan view thereof. Wire insertion portion 5b is to chromatic and the hole 8b for inserting the electric wire 19 as described above, a smaller width than the hole 8b, the insertion portion 9b communicating between the opening edge of the hole portion 8b and the case 1 As shown in FIG. 5, the position of the insertion portion 9b is formed at one end of the hole portion 8b.

電線１９は例えば、内部に３本の心線２０が直線状に並び外被で被覆された断面長円形ないし楕円形のＶＡケーブルであり、その短手方向の幅Ｐ１が挿入部９ｂの幅Ｑよりも小さく長手方向の幅Ｐ２が挿入部９ｂの幅Ｑよりも大きくなっている。一方穴部８ｂは電線１９の断面形状に略相似な偏平形ないし長円形状である。穴部８ｂの長手方向はケース１の開口縁に沿い、挿入部９ｂの幅方向と平行である。また図５に示すように、挿入部９ｂの幅Ｑが穴部８ｂの短手方向の幅よりも大きくなっている。 The electric wire 19 is, for example, an VA cable having an oval or elliptical cross section in which three core wires 20 are linearly arranged and covered with a jacket, and the width P1 in the short direction is the width Q of the insertion portion 9b. The longitudinal width P2 is smaller than the width Q of the insertion portion 9b. On the other hand, the hole 8b has a flat or oval shape that is substantially similar to the cross-sectional shape of the electric wire 19. The longitudinal direction of the hole 8b is along the opening edge of the case 1 and parallel to the width direction of the insertion portion 9b. Further, as shown in FIG. 5, the width Q of the insertion portion 9b is larger than the width of the hole portion 8b in the short direction.

電線１９は端部がケース１内に位置するようにケース１の周壁７に交差した状態にして長手方向を挿入部９ｂに差し込み、穴部８ｂに達したところで想像線で示すように９０度回すことにより穴部８ｂに納まる。したがって、電線１９をそのまま矢印のように持ち上げても電線１９を逆に回動しない限り、電線１９が挿入部９ｂから取り出すことができない。電線１９の表面と穴部８ｂの縁部とは摩擦があるため、自然に滑り出ることは困難である。   The electric wire 19 is inserted into the insertion portion 9b with the end portion intersecting the peripheral wall 7 of the case 1 so that the end portion is located in the case 1, and when it reaches the hole portion 8b, it is turned 90 degrees as indicated by an imaginary line. This fits in the hole 8b. Therefore, even if the electric wire 19 is lifted as shown by the arrow, the electric wire 19 cannot be taken out from the insertion portion 9b unless the electric wire 19 is rotated in the reverse direction. Since there is friction between the surface of the electric wire 19 and the edge of the hole 8b, it is difficult to slip out naturally.

この結果、電線１９をケース１に挿通する場合、まず電線１９に圧着端子などの接続具を接続しておき、この状態で接続具がケース１内に位置するようにケース１の側壁をまたいで電線１９を挿入部９ｂより押し込むことで簡単に電線挿通部５ｂに挿通することができる。その場合、必要に応じて接続具を電線に接続したままで電線挿通部５ｂから外すこともできる。また、ケース１の開口縁を蓋体２で閉じる際に上記のように電線１９が挿入部９ｂから容易に外れることがないので、蓋体２の取付け作業が容易になる。したがって、従来と比べて電線挿通作業が容易であることは明らかである。   As a result, when the electric wire 19 is inserted into the case 1, first, a connection tool such as a crimp terminal is connected to the electric wire 19, and the side wall of the case 1 is straddled so that the connection tool is located in the case 1 in this state. The electric wire 19 can be easily inserted into the electric wire insertion portion 5b by being pushed in from the insertion portion 9b. In that case, it can also remove from the electric wire insertion part 5b, with the connection tool connected to the electric wire as needed. Moreover, since the electric wire 19 is not easily detached from the insertion portion 9b as described above when the opening edge of the case 1 is closed with the lid 2, the attaching operation of the lid 2 is facilitated. Therefore, it is clear that the wire insertion work is easier than in the prior art.

図７は電線挿通部５ａの詳細を示している。この電線挿通部５ａに挿通する電線１８は４本の心線からなり外形が断面円形の丸電線を用いている。電線挿通部５ａの挿入部９ａは電線１８の外径よりも大きい幅を有し、穴部８ａは丸形である。また現場で電線挿通部５ａを形成するため、挿入部９ａおよび穴部８ａは切り溝により現場で打ち抜くことができるノックアウト穴としている。ノックアウト穴は電線の外径に対応して異なる幅の２つの挿入部９ａと、ブッシング１０の径に対応して異なる径の２つの穴部８ａを形成している。   FIG. 7 shows details of the wire insertion portion 5a. The electric wire 18 inserted into the electric wire insertion portion 5a is a round electric wire made of four core wires and having a circular outer shape. The insertion portion 9a of the electric wire insertion portion 5a has a width larger than the outer diameter of the electric wire 18, and the hole portion 8a is round. Moreover, in order to form the electric wire insertion part 5a in the field, the insertion part 9a and the hole part 8a are made into the knockout hole which can be punched in the field with a cut groove. The knockout hole has two insertion portions 9a having different widths corresponding to the outer diameter of the electric wire and two hole portions 8a having different diameters corresponding to the diameter of the bushing 10.

図８は電線１８の挿通状態を示している。ブッシング１０の孔１０ｂに通した電線１８を、挿入部９ａより穴部８ａに挿入し、ブッシング１０を電線１８に沿って移動して、ブッシング１０を穴部８ａに嵌合している。ブッシング１０はゴム製であり、外周に周溝１０ａを形成し、周溝１０ａを穴部８ａの縁部に嵌合している。この場合、ブッシング１０の一端を弾性変形して穴部８ａの一端側より他端側に通している。ブッシング１０が穴部８ａに嵌合すると、挿入部９ａは穴部８ａの径よりも小さいため、ブッシング１０が挿入部９ａを通して取り出されることがなく、このため電線１８が挿入部９ａから容易に抜け出ることがない。さらに挿入部９ａは蓋体２の扉枠３に押さえられている。   FIG. 8 shows an inserted state of the electric wire 18. The electric wire 18 passed through the hole 10b of the bushing 10 is inserted into the hole 8a from the insertion portion 9a, the bushing 10 is moved along the electric wire 18, and the bushing 10 is fitted into the hole 8a. The bushing 10 is made of rubber, has a peripheral groove 10a formed on the outer periphery, and the peripheral groove 10a is fitted to the edge of the hole 8a. In this case, one end of the bushing 10 is elastically deformed and passed from the one end side of the hole 8a to the other end side. When the bushing 10 is fitted into the hole portion 8a, the insertion portion 9a is smaller than the diameter of the hole portion 8a, so that the bushing 10 is not taken out through the insertion portion 9a, and thus the electric wire 18 is easily pulled out from the insertion portion 9a. There is nothing. Further, the insertion portion 9 a is held by the door frame 3 of the lid 2.

In the first embodiment and the second embodiment, the insertion portion 9b is formed at one end of the hole portion 8b. In the third embodiment, the insertion portion 9b is formed at the center position of the hole portion 8b. ing.

この発明の第４の実施の形態を図１２および図１３により説明する。これは第１の実施の形態において、電線挿通部５ａが電線クリップ部１３に形成され、電線クリップ部１３を取付ける凹部をケース１に形成し、取付手段としてねじ１５により電線クリップ部１３を凹部に取付けている。   A fourth embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the electric wire insertion portion 5a is formed in the electric wire clip portion 13, a concave portion for attaching the electric wire clip portion 13 is formed in the case 1, and the electric wire clip portion 13 is made into a concave portion by a screw 15 as an attaching means.
