Description

本発明は、電柱の腕金の下部に吊り上げる態様で設置される柱上設置型電気機器に関するものである。 TECHNICAL FIELD The present invention relates to a pole-mounted electric device that is installed in a manner of being suspended from a lower part of an arm of a utility pole.

柱上設置型電気機器の一つである柱上開閉器においては、上面に雨水等を溜まり難くするために、従来、例えば、図１３に示すように、直方体形状の上面１０１と長手方向の両側面１０２の間に上面１０１から側面１０２の方向に流れる傾斜面１０３を設けたケース１００が用いられている。このケース１００は、直方体のケース１００の上面を切妻屋根の形状にしたものであるが、最頂部を水平に切り落として上面１０１とし、この上面１０１の部分に電柱の腕金の下側に吊下げるための固定部材（図示省略）が設けられている。 In order to make it difficult to collect rainwater or the like on the top surface of a pole switch, which is one of the pole-mounted electrical devices, conventionally, for example, as shown in FIG. 13, a rectangular parallelepiped top surface 101 and both longitudinal sides A case 100 in which an inclined surface 103 that flows in the direction from the upper surface 101 to the side surface 102 is provided between the surfaces 102 is used.

従来の柱上設置型電気機器は、ケースに設けられている電柱の腕金への固定部材が当該ケースの底面が腕金と平行になるように固定する構造であるので、ケースの形状として、上面の最頂部若しくは最頂面から両側面に雨水等を流すための傾斜面１０３，２０３を有する形状にしなければならず、ケースの立体形状が複雑になっている。 The conventional pole-mounted electric device has a structure in which the fixing member to the armrest of the power pole provided in the case is fixed so that the bottom surface of the case is parallel to the armrest. The shape must have inclined surfaces 103 and 203 for allowing rainwater or the like to flow from the topmost portion of the upper surface or from the topmost surface to both sides, and the three-dimensional shape of the case is complicated.

このため、例えば、ケースをプレス圧出加工で製作する場合、プレス金型が高額になり、ケースの製造コストが増大するという問題がある。また、特許文献１に示されるように、ケースを折り曲げ加工で製作すれば、プレス金型は不要になるが、この場合は、ケースの材料（板材）の歩留まりが悪く、板材の切断加工や溶接工程のために作業効率が低下するという問題がある。 For this reason, for example, when the case is manufactured by press extrusion, there is a problem that the press mold becomes expensive and the manufacturing cost of the case increases. Also, as shown in Patent Document 1, if the case is manufactured by bending, a press die is not necessary, but in this case, the yield of the case material (plate material) is poor, and the plate material is cut and welded. There is a problem that work efficiency decreases due to the process.

電気機器のケースを傾斜面１０３や屋根２０３を有しない簡単な直方体の形状にすれば、ケースの製作コストや作業効率などを向上させることができるが、この場合は、ケースの上面に雨水等が溜まり易くなり、その雨水等によってケースが腐食し、ケースの寿命が短くなるという問題が生じる。 If the case of the electrical device is formed in a simple rectangular parallelepiped shape without the inclined surface 103 or the roof 203, the production cost of the case and the work efficiency can be improved. In this case, rainwater or the like is present on the upper surface of the case. It tends to accumulate, and the case is corroded by rainwater or the like, resulting in a problem that the life of the case is shortened.

The support member 1021 is manufactured by bending a metal plate that is substantially the same as the longitudinal dimension of the lid 101B so that the cross-sectional shape is U-shaped. A central portion in the width direction of the support member 1021 is a support portion 1021A for supporting the lifting member 1022, and both ends in the width direction are folded outward at both ends in the longitudinal direction of the support member 1021. Four fixing portions 1021B for fixing to the lid 101B are formed.

支持部材１０２１は、当該支持部材１０２１の長手方向の中心線を蓋１０１Ｂの長手方向の中心線（図２の幅方向の中心Ｏを通る中心線）に合わせて４つの固定部１０２１Ｂをボルト締めすることにより蓋１０１Ｂの上面に固定されている。 The support member 1021 is bolted to the four fixing portions 1021B by matching the longitudinal center line of the support member 1021 with the longitudinal center line of the lid 101B (center line passing through the center O in the width direction in FIG. 2). This is fixed to the upper surface of the lid 101B.

吊上げ部材１０２２は、筐体１０１を吊り上げるために筐体１０１側に設けられるフック部材である。吊上げ部材１０２２は、後述するように、取付部１０２で開閉器１を腕金３の下部に吊り上げる態様で固定したとき、蓋１０１Ｂの上面を腕金３の下面に対して所定の傾斜角θ［ｄｅｇ］で傾斜させる部材としても機能する。 The lifting member 1022 is a hook member provided on the housing 101 side to lift the housing 101. As will be described later, the lifting member 1022 is fixed at a predetermined inclination angle θ [with respect to the lower surface of the arm metal 3 when the switch 1 is fixed to the lower portion of the arm metal 3 by the mounting portion 102. deg] also functions as a member inclined.

吊上げ部材１０２２は、支持部材１０２１の長手方向の寸法よりも短い寸法Ｌ１を有する縦断面形状がコの字形の部材である。吊上げ部材１０２２は、所定長の金属製の板材の長手方向の両端部を同一方向に直角に折り曲げて製作されている。板材を折り曲げた両端部は、筐体１０１を吊り上げるためのフック部１０２２Ａ，１０２２Ｂとなり、２つのフック部１０２２Ａ，１０２２Ｂに挟まれた部分は、吊上げ部材１０２２を支持部材１０２１の支持部１０２１Ａに固定するための固定部１０２２Ｃとなっている。 The lifting member 1022 is a member having a U-shaped longitudinal sectional shape having a dimension L1 shorter than the dimension of the support member 1021 in the longitudinal direction. The lifting member 1022 is manufactured by bending both ends in the longitudinal direction of a metal plate having a predetermined length at right angles in the same direction. Both ends of the bent plate material become hook portions 1022A and 1022B for lifting the housing 101, and the portion sandwiched between the two hook portions 1022A and 1022B fixes the lifting member 1022 to the support portion 1021A of the support member 1021. The fixing portion 1022C for this purpose.

２つのフック部１０２２Ａ，１０２２Ｂは、取付部１０２で開閉器１を腕金３の下部に吊り上げる態様で固定したとき、支持部材１０２１と腕金３の下面との間の距離を互いに異ならせて蓋１０１Ｂの上面を腕金３の下面に対して傾斜させる機能も果たす。 The two hook portions 1022A and 1022B are lids with different distances between the support member 1021 and the lower surface of the arm metal 3 when the switch 1 is fixed to the lower portion of the arm metal 3 by the attachment portion 102. It also functions to incline the upper surface of 101B with respect to the lower surface of the brace 3.

本実施の形態では、蓋１０１Ｂの上面に支持部材１０２１を介して吊上げ部材１０２２を取り付ける構造にしているが、吊上げ部材１０２２を直接、蓋１０１Ｂの上面に取り付ける構造でもよい。 In the present embodiment, the lifting member 1022 is attached to the upper surface of the lid 101B via the support member 1021, but the lifting member 1022 may be directly attached to the upper surface of the lid 101B.

フック部１０２２Ａ，１０２２Ｂは、同一寸法の横長長方形を有し、横方向の中心線上の適所に締付部材１０２４を取り付けるための二対の孔（図示省略）が穿設されている。内側の組の孔の横方向の寸法と外側の組の孔の横方向の寸法は、腕金３のサイズと締付部材１０２４のサイズに基づく規定の寸法である。図１，図２では、内側の組の孔に２個の締付部材１０２４を取り付けた場合を示しており、腕金３の幅寸法をＬ２［ｍｍ］とし、締付部材１０２４の直径をφ［ｍｍ］とすると、内側の組の孔の間隔は凡そ（Ｌ２＋φ）［ｍｍ］に設定されている。 The hook portions 1022A and 1022B have a horizontally long rectangular shape having the same dimensions, and two pairs of holes (not shown) for attaching the tightening member 1024 are formed at appropriate positions on the center line in the horizontal direction. The lateral dimension of the inner set of holes and the lateral dimension of the outer set of holes are prescribed dimensions based on the size of the arm metal 3 and the size of the fastening member 1024. FIGS. 1 and 2 show the case where two fastening members 1024 are attached to the inner set of holes. The width of the arm metal 3 is L2 [mm], and the diameter of the fastening member 1024 is φ. Assuming [mm], the interval between the holes in the inner group is set to about (L2 + φ) [mm].

一方のフック部１０２２Ａ（図１では右側のフック部）には、先端の中央部（図２では、上端の中央部）に幅寸法が腕金３の幅寸法Ｌ２と略同一で所定の深さｄ［ｍｍ］を有する切欠部１０２２Ｄが設けられている。切欠部１０２２Ｄの底辺は、開閉器１を取付部１０２で腕金３に固定する際に、当該腕金３の下面をフック部１０２２Ａに当接させる部分である。他方のフック部１０２２Ｂ（図１では左側のフック部）には、切欠部１０２２Ｄは設けられていない。このため、開閉器１を取付部１０２で腕金３に固定する際、フック部１０２２Ｂは先端（図１では上端）が腕金３の下面に当接する。 One hook portion 1022A (the right hook portion in FIG. 1) has a predetermined width with a width dimension substantially the same as the width dimension L2 of the arm metal 3 at the center portion at the tip (the center portion at the upper end in FIG. 2). A notch 1022D having d [mm] is provided. The bottom side of the cutout portion 1022D is a portion where the lower surface of the arm metal 3 is brought into contact with the hook portion 1022A when the switch 1 is fixed to the arm metal 3 by the mounting portion 102. The other hook portion 1022B (the left hook portion in FIG. 1) is not provided with a notch portion 1022D. For this reason, when the switch 1 is fixed to the arm metal 3 by the attachment portion 102, the tip of the hook portion 1022 B (the upper end in FIG. 1) abuts the lower surface of the arm metal 3.

フック部１０２２Ａの切欠部１０２２Ｄの底辺とフック部１０２２Ｂの上辺は本発明の当接点に相当し、フック部１０２２Ａ，１０２２Ｂにおける両当接点の位置が異なるので、フック部１０２２Ａの当接点とフック部１０２２Ｂの当接点を結ぶ当接線は、蓋１０１Ｂの上面に対して所定の傾斜角θ［ｄｅｇ］で傾斜している。 The bottom side of the notch portion 1022D of the hook portion 1022A and the upper side of the hook portion 1022B correspond to the contact points of the present invention, and the positions of both contact points in the hook portions 1022A and 1022B are different. Therefore, the contact point of the hook portion 1022A and the hook portion 1022B The contact line connecting the contact points is inclined at a predetermined inclination angle θ [deg] with respect to the upper surface of the lid 101B.

支持部材１０２１の高さ寸法をＨ１［ｍｍ］、フック部１０２２Ａ，１０２２Ｂの折り曲げ寸法をＨ２［ｍｍ］とすると、開閉器１を取付部１０２で腕金３に固定したとき、フック部１０２２Ａは、腕金３の下面と蓋１０１Ｂの上面との間の距離を（Ｈ１＋Ｈ２−ｄ）［ｍｍ］に設定し、フック部１０２２Ｂは、腕金３の下面と蓋１０１Ｂの上面との間の距離を（Ｈ１＋Ｈ２）［ｍｍ］に設定する。従って、開閉器１は、蓋１０１Ｂの上面が腕金３の下面に対して所定の傾斜角θ［ｄｅｇ］で傾斜するように、腕金３の下部に取り付けられる。所定の傾斜角θは、θ＝ｔａｎ^−１（ｄ／Ｌ１）［ｄｅｇ］である。 When the height dimension of the support member 1021 is H1 [mm] and the bending dimension of the hook portions 1022A and 1022B is H2 [mm], when the switch 1 is fixed to the arm metal 3 by the mounting portion 102, the hook portion 1022A is The distance between the lower surface of the arm metal 3 and the upper surface of the lid 101B is set to (H1 + H2-d) [mm], and the hook portion 1022B sets the distance between the lower surface of the arm metal 3 and the upper surface of the lid 101B ( H1 + H2) [mm]. Therefore, the switch 1 is attached to the lower part of the arm metal 3 so that the upper surface of the lid 101B is inclined with respect to the lower surface of the arm metal 3 at a predetermined inclination angle θ [deg]. The predetermined inclination angle θ is θ = tan ⁻¹ (d / L1) [deg].

本実施の形態では、フック部１０２２Ａ，１０２２Ｂの形状を同一にし、フック部１０２２Ａの上辺に切欠部１０２２Ｄを設けて当該フック部１０２２Ａの腕金３の下面に当接する位置を上辺からｄだけ下げるようにしているが、フック部１０２２Ａの折り曲げ寸法を（Ｈ２−ｄ）にしてフック部１０２２Ａの上辺を腕金３の下面に当接させるようにしてもよい。 In the present embodiment, the hook portions 1022A and 1022B have the same shape, and a notch portion 1022D is provided on the upper side of the hook portion 1022A so that the position contacting the lower surface of the arm metal 3 of the hook portion 1022A is lowered by d from the upper side. However, the hook part 1022A may be bent to (H2-d) so that the upper side of the hook part 1022A is brought into contact with the lower surface of the arm metal 3.

本実施の形態では、吊上げ部材１０２２の固定部１０２２Ｃの長さ寸法Ｌ１と切欠部１０２２Ｄの深さｄが、例えば、傾斜角θが１［ｄｅｇ］程度となるように設計されている。 In the present embodiment, the length dimension L1 of the fixing portion 1022C of the lifting member 1022 and the depth d of the notch portion 1022D are designed such that the inclination angle θ is about 1 [deg], for example.

締付部材１０２４は、Ｌ字状に屈曲したボルト１０２４−１と、このボルト１０２４−１の一方の端部に形成された雄ネジに螺合するナット１０２４−２とで構成される。ボルト１０２４−１の他方の端部は、略直角に屈曲され、その先端に当該先端を潰して頭部が形成されている。ボルト１０２４−１の雄ネジが切られた直線部の長さは、腕金３の高さ寸法よりも十分に長く設計されている。 The tightening member 1024 includes a bolt 1024-1 bent in an L shape and a nut 1024-2 that is screwed into a male screw formed at one end of the bolt 1024-1. The other end of the bolt 1024-1 is bent at a substantially right angle, and the tip is crushed at the tip to form a head. The length of the straight portion where the male screw of the bolt 1024-1 is cut is designed to be sufficiently longer than the height of the arm bracket 3.

２本の締付部材１０２４Ａ，１０２４Ｂは、それぞれボルト１０２４−１の直線部をフック部１０２２Ａの外側から孔に通して当該直線部がフック部１０２２Ａに対して垂直に上方に立ち上がるようにセットし、直線部の先端の雄ネジにナット１０２４−２を螺合して、フック部１０２２Ａに固着されている。締付部材１０２４Ａ，１０２４Ｂの屈曲部の先端には頭部が形成されており、その頭部の径は孔よりも大きいので、当該屈曲部がフック部１０２２Ａの孔から脱落することはない。２本の締付部材１０２４Ｃ，１０２４Ｄも締付部材１０２４Ａ，１０２４Ｂと同様の方法で、フック部１０２２Ｂに固着されている。 The two fastening members 1024A and 1024B are set so that the straight part of the bolt 1024-1 passes through the hole from the outside of the hook part 1022A and the straight part rises vertically upward with respect to the hook part 1022A. A nut 1024-2 is screwed into a male screw at the tip of the straight line portion, and is fixed to the hook portion 1022A. A head is formed at the tip of the bent portion of the fastening members 1024A and 1024B, and the diameter of the head is larger than the hole, so that the bent portion does not fall out of the hole of the hook portion 1022A. The two fastening members 1024C and 1024D are also fixed to the hook portion 1022B in the same manner as the fastening members 1024A and 1024B.

座金１０２３Ａは、フック部１０２２Ａに固着された２本の締付部材１０２４Ａ，１０２４Ｂの間に腕金３を配置した状態で当該腕金３の上面より上方に飛び出た上端の雄ネジにそれぞれナット１０２４−２を螺合する際、２つのナット１０２４−２と腕金３の上面の間に挟み込む締付用の板材である。座金１０２３Ｂは、フック部１０２２Ｂに固着された２本の締付部材１０２４Ｃ，１０２４Ｄの間に腕金３を配置した状態で当該腕金３の上面より上方に飛び出た上端の雄ネジにそれぞれナット１０２４−２を螺合する際、２つのナット１０２４−２と腕金３の上面の間に挟み込む締付用の板材である。以下の説明では、座金１０２３Ａ，１０２３Ｂを代表する場合は、「座金１０２３」と称する。 The washer 1023A is provided with a nut 1024 on each male screw at the upper end protruding above the upper surface of the arm metal 3 in a state where the arm metal 3 is disposed between the two fastening members 1024A and 1024B fixed to the hook portion 1022A. -2 is a plate member for fastening which is sandwiched between the two nuts 1024-2 and the upper surface of the arm metal 3 when screwing -2.

In the following description, when the washers 1023A and 1023B are represented, they are referred to as “washers 1023”.

座金１０２３は、腕金３の幅寸法Ｌ２よりも十分に長い長さ寸法を有する同一の長方形状を有する板部材である。座金１０２３の長手方向の中心線上には、内側の組の孔の間隔（Ｌ２＋φ）と同一の間隔で一対の孔（図示省略）が穿設されている。座金１０２３の孔は、締付部材１０２４の上端部を通すための孔である。 The washer 1023 is a plate member having the same rectangular shape having a length that is sufficiently longer than the width L2 of the arm 3. On the center line in the longitudinal direction of the washer 1023, a pair of holes (not shown) are formed at the same interval as the interval (L2 + φ) of the inner set of holes. The hole of the washer 1023 is a hole through which the upper end portion of the fastening member 1024 is passed.

次に、図４〜図６を用いて、開閉器１の取付部１０２による腕金３への取り付け方法について説明する。 Next, with reference to FIGS. 4 to 6, a method of attaching the arm 1 to the arm metal 3 by the attaching portion 102 of the switch 1 will be described.

図４は、開閉器１を腕金３に取り付ける直前の状態を示す正面図、図５は、開閉器１の取付部１０２の所定の位置に腕金３を配置した状態（締付部材１０２４Ａと締付部材１０２４Ｂの間と締付部材１０２４Ｃと締付部材１０２４Ｄの間に腕金３を配置した状態）を示す正面図、図６は、開閉器１を取付部１０２で腕金３に固定した状態を示す正面図である。なお、図４〜図６では、開閉器１の筐体１０１の形状は簡略化して描いている。 4 is a front view showing a state immediately before the switch 1 is attached to the arm metal 3, and FIG. 5 is a state in which the arm metal 3 is disposed at a predetermined position of the attachment portion 102 of the switch 1 (with the fastening member 1024A and FIG. 6 is a front view showing a state in which the arm metal 3 is disposed between the tightening members 1024B and between the tightening members 1024C and 1024D. FIG. It is a front view which shows a state. 4 to 6, the shape of the casing 101 of the switch 1 is simplified.

開閉器１は、取付部１０２の座金１０２３Ａと締付部材１０２４Ａ，１０２４Ｂを吊上げ部材１０２２のフック部１０２２Ａに取り付け、取付部１０２の座金１０２３Ｂと締付部材１０２４Ｃ，１０２４Ｄを吊上げ部材１０２２のフック部１０２２Ｂに取り付けた状態（図４に示す状態）で電柱２の取付現場に運ばれる。 The switch 1 attaches the washer 1023A and the fastening members 1024A and 1024B of the attachment portion 102 to the hook portion 1022A of the lifting member 1022, and connects the washer 1023B and the fastening members 1024C and 1024D of the attachment portion 1022 to the hook portion 1022B of the lifting member 1022. Is carried to the installation site of the utility pole 2 in the state of being attached to (the state shown in FIG. 4).

取付現場では、作業者は、まず、締付部材１０２４Ａ，１０２４Ｂに取り付けられている座金１０２３Ａ，１０２３Ｂとナット１０２４−２を外して開閉器１を電柱２の腕金３の下方位置に配置する。このとき、作業者は、取付部１０２の吊上げ部材１０２２の長手方向が腕金３と平行で、且つ、フック部１０２２Ａが電柱２側となる向きの姿勢にして、開閉器１を配置する（図５の状態参照）。また、作業者は、フック部１０２２Ａから立ち上がる締付部材１０２４Ａと締付部材１０２４Ｂのボルト１０２４−１の間とフック部１０２２Ｂから立ち上がる締付部材１０２４Ｃと締付部材１０２４Ｄのボルト１０２４−１の間に腕金３が挟まれるように、開閉器１を配置する（図５の状態参照）。 At the installation site, an operator first removes the washers 1023A and 1023B and nuts 104-2 attached to the fastening members 1024A and 1024B, and places the switch 1 at a position below the arm metal 3 of the utility pole 2. At this time, the operator places the switch 1 in such a posture that the longitudinal direction of the lifting member 1022 of the attachment portion 102 is parallel to the arm metal 3 and the hook portion 1022A is on the electric pole 2 side (see FIG. (See state 5). Also, the operator can place between the fastening member 1024A rising from the hook portion 1022A and the bolt 1024-1 of the fastening member 1024B, and between the fastening member 1024C rising from the hook portion 1022B and the bolt 1024-1 of the fastening member 1024D. The switch 1 is arranged so that the arm metal 3 is sandwiched (see the state of FIG. 5).

次に、作業者は、腕金３の上面より上方に突出している締付部材１０２４Ａのボルト１０２４−１と締付部材１０２４Ｂのボルト１０２４−１に座金１０２３Ａを装着し、両ボルト１０２４−１にナット１０２４−２を螺合する。また、作業者は、腕金３の上面より上方に突出している締付部材１０２４Ｃのボルト１０２４−１と締付部材１０２４Ｄのボルト１０２４−１に座金１０２３Ｂを装着し、両ボルト１０２４−１にナット１０２４−２を螺合する。 Next, the operator attaches the washer 1023A to the bolts 1024-1 of the tightening member 1024A and the bolts 1024-1 of the tightening member 1024B protruding upward from the upper surface of the arm metal 3, and the bolts 1024-1 are attached to both bolts 1024-1. The nut 1024-2 is screwed. Further, the operator attaches the washer 1023B to the bolts 1024-1 of the fastening member 1024C and the bolts 1024-1 of the fastening member 1024D protruding upward from the upper surface of the arm metal 3, and the nuts are attached to both bolts 1024-1. 1024-2 is screwed.

そして、作業者は、４個のナット１０２４−２のトルクが所定のトルクに達するまで締め付ける。作業者が４個のナット１０２４−２を締めることにより、吊上げ部材１０２２のフック部１０２２Ａとフック部１０２２Ｂが上昇する（図６の状態参照）。吊上げ部材１０２２の上昇により、フック部１０２２Ａの切欠部１０２２Ｄの底辺とフック部１０２２Ｂの上辺が腕金３の下面に当接し、その後はフック部１０２２Ａとフック部１０２２Ｂとが座金１０２３Ａと座金１０２３Ｂとによってそれぞれ所定の締付力で腕金３を締め付け、取付部１０２が腕金３に固定される（図１の状態参照）。これにより、開閉器１の腕金３への取付作業は終了する。 Then, the operator tightens until the torque of the four nuts 1024-2 reaches a predetermined torque. When the operator tightens the four nuts 1024-2, the hook portion 1022A and the hook portion 1022B of the lifting member 1022 rise (see the state of FIG. 6). Due to the lifting of the lifting member 1022, the bottom of the notch 1022D of the hook portion 1022A and the upper side of the hook portion 1022B abut against the lower surface of the arm metal 3, and then the hook portion 1022A and the hook portion 1022B are joined by the washer 1023A and the washer 1023B. The arm 3 is tightened with a predetermined tightening force, and the mounting portion 102 is fixed to the arm metal 3 (see the state of FIG. 1). Thereby, the attachment work to the armrest 3 of the switch 1 is completed.

次に、開閉器１の取付部１０２の作用と効果について、説明する。 Next, the operation and effect of the mounting portion 102 of the switch 1 will be described.

締付部材１０２４Ａ，１０２４Ｂとフック部１０２２Ａによる腕金３のボルト締め作業では、フック部１０２２Ａが上昇して当該フック部１０２２Ａの切欠部１０２２Ｄの底辺が腕金３の下面に当接した後、締付力が所定の締付力に達した時点で取付部１０２の右端側が固定される。また、締付部材１０２４Ｃ，１０２４Ｄとフック部１０２２Ｂによる腕金３のボルト締め作業では、フック部１０２２Ｂが上昇して当該フック部１０２２Ｂの上辺が腕金３の下面に当接した後、締付力が所定の締付力に達した時点で取付部１０２の左端側が固定される。 In the bolting operation of the arm metal 3 by the tightening members 1024A and 1024B and the hook portion 1022A, the hook portion 1022A is raised and the bottom side of the notch portion 1022D of the hook portion 1022A is brought into contact with the lower surface of the arm metal 3 and then tightened. When the applied force reaches a predetermined tightening force, the right end side of the mounting portion 102 is fixed. Further, in the bolting operation of the arm metal 3 by the tightening members 1024C and 1024D and the hook portion 1022B, after the hook portion 1022B rises and the upper side of the hook portion 1022B contacts the lower surface of the arm metal 3, the tightening force When a predetermined tightening force is reached, the left end side of the mounting portion 102 is fixed.

従って、開閉器１の腕金３への取付作業が終了すると、フック部１０２２Ａの腕金３への当接位置における蓋１０１Ｂの上面から腕金３の下面までの距離が（Ｈ１＋Ｈ２−ｄ）［ｍｍ］となり、フック部１０２２Ｂの腕金３への当接位置における蓋１０１Ｂの上面から腕金３の下面までの距離が（Ｈ１＋Ｈ２）［ｍｍ］となるので、開閉器１は、蓋１０１Ｂの上面が、図１に示すように、腕金３の軸方向Ｍに対して、蓋１０１Ｂの左側面側（腕金３の先端側）が下方向に傾くように、傾斜角θで傾斜した状態で腕金３に固定される。 Therefore, when the operation of attaching the switch 1 to the arm metal 3 is completed, the distance from the upper surface of the lid 101B to the lower surface of the arm metal 3 at the position where the hook portion 1022A contacts the arm metal 3 is (H1 + H2-d) [ mm], and the distance from the upper surface of the lid 101B to the lower surface of the arm metal 3 at the contact position of the hook portion 1022B with the arm metal 3 is (H1 + H2) [mm]. However, as shown in FIG. 1, in a state where the left side surface of the lid 101B (the front end side of the arm metal 3) is inclined downward with respect to the axial direction M of the arm metal 3 at an inclination angle θ. It is fixed to the brace 3.

電柱２は地面に対して垂直に設置され、腕金３は電柱２の上部に当該電柱２に対して直角に取り付けられるので、腕金３の軸方向Ｍは水平方向である。従って、開閉器１は、蓋１０１Ｂの上面が水平面に対して傾斜角θで傾斜した状態で腕金３に固定される。 The utility pole 2 is installed perpendicular to the ground, and the arm 3 is attached to the upper part of the utility pole 2 at a right angle to the utility pole 2, so that the axial direction M of the arm 3 is the horizontal direction. Therefore, the switch 1 is fixed to the brace 3 with the upper surface of the lid 101B inclined at an inclination angle θ with respect to the horizontal plane.

本実施の形態に係る開閉器１では、取付部１０２が蓋１０１Ｂの上面を水平面に対して傾斜させて腕金３に固定するので、蓋１０１Ｂの上面を平坦にすることにより、図７に示すように、蓋１０１Ｂの上面に雨や雪が掛かった場合でも雨水等を傾斜させた上面に沿って流すことができ、蓋１０１Ｂの上面に雨水等を溜まり難くすることができる。従って、蓋１０１Ｂの上面が平坦な形状であっても雨水等に対する耐腐食性を低下させることがない。 In the switch 1 according to the present embodiment, the mounting portion 102 tilts the upper surface of the lid 101B with respect to the horizontal plane and fixes the lid 101B to the arm metal 3. Therefore, by flattening the upper surface of the lid 101B, FIG. As described above, even when rain or snow is applied to the upper surface of the lid 101B, rainwater or the like can be caused to flow along the inclined upper surface, and rainwater or the like can be hardly accumulated on the upper surface of the lid 101B. Therefore, even if the upper surface of the lid 101B has a flat shape, the corrosion resistance against rainwater or the like is not lowered.

従来の開閉器の取付部は、蓋の上面が水平になる状態で腕金３に固定する構造であったので、蓋の上面に雨や雪が掛かった場合に雨水等が蓋の上面に溜まらないように、蓋の上面に山型の傾斜面を形成する必要があったが、本実施の形態に係る開閉器１では、蓋１０１Ｂの上面の形状を平坦にすることができるので、筐体１０１全体も凸凹の少ない簡単な長方体形状にすることができ、筐体１０１の製作を簡単にすることができる。 The mounting part of the conventional switch has a structure in which the upper surface of the lid is fixed to the armrest 3 in a state where the upper surface of the lid is horizontal, so that rain or the like does not collect on the upper surface of the lid when rain or snow is applied to the upper surface of the lid. As described above, it is necessary to form a mountain-shaped inclined surface on the upper surface of the lid. However, in the switch 1 according to the present embodiment, the shape of the upper surface of the lid 101B can be flattened. The whole can be made into a simple rectangular shape with few irregularities, and the manufacture of the housing 101 can be simplified.

例えば、蓋１０１Ｂのプレス加工時、圧出加工をせず、板材の折り曲げ加工のみによって製作することができるので、圧出加工を用いた場合に比べて製作費用を低減することができる。また、蓋１０１Ｂの外観形状が凸凹の少ない簡単な長方体形状であるので、板材の折り曲げ加工を採用した場合でも折り曲げ工程が従来よりも簡単になり、山形に折り曲げた場合よりも板材の歩留まりや、切断作業や溶接作業における作業性を向上させることができる。更に、気密溶接加工なども不要になるので、気密性や寸法などの品質の向上も図ることができる。 For example, when the lid 101B is pressed, it can be manufactured only by bending the plate material without performing the pressing process, so that the manufacturing cost can be reduced as compared with the case where the pressing process is used. In addition, since the lid 101B has a simple rectangular shape with few irregularities, the folding process is easier than before even when a plate is bent, and the yield of the plate is higher than when folded in a mountain shape. In addition, workability in cutting work and welding work can be improved. Furthermore, since airtight welding is not necessary, quality such as airtightness and dimensions can be improved.

上記実施の形態では、板材の両端部を折り曲げて２個のフック部１０２２Ａ，１０２２Ｂを一体形成する方法で吊上げ部材１０２２を製作しているので、吊上げ部材のフック部が２個になっているが、３個以上のフック部を有する吊上げ部材を用いてもよい。例えば、図８に示すように、板材の中間部を折り曲げて３個のフック部１０２２Ａ，１０２２Ｂ，１０２２Ｅを一体形成した吊上げ部材１０２２’を用いてもよい。 In the above embodiment, since the lifting member 1022 is manufactured by bending both ends of the plate material and integrally forming the two hook portions 1022A and 1022B, the number of hook portions of the lifting member is two. A lifting member having three or more hook portions may be used. For example, as shown in FIG. 8, a lifting member 1022 'in which three intermediate hook portions 1022A, 1022B, and 1022E are integrally formed by bending an intermediate portion of a plate material may be used.

図８に示す吊上げ部材１０２２’は、図１に示す吊上げ部材１０２２の固定部１０２２Ｃの中央を折り曲げてフック部１０２２Ｅを形成し、当該フック部１０２２Ｅの上辺に深さｄ’（＜ｄ）の切欠部１０２２Ｄ’を設けたものである。吊上げ部材１０２２’では、フック部１０２２Ａの切欠部１０２２Ｄの底辺、フック部１０２２Ｅの切欠部１０２２Ｄ’の底辺及びフック部１０２２Ｂの上辺がそれぞれ腕金３の下面に当接する当接部となる。切欠部１０２２Ｄ’の深さｄ’［ｍｍ］は、これらの当接部を結ぶ直線が、図８に示すように、腕金３の軸方向Ｍに対して傾斜角θで傾斜した直線となるように設定されている。 The lifting member 1022 ′ shown in FIG. 8 is formed by bending the center of the fixing portion 1022C of the lifting member 1022 shown in FIG. 1 to form a hook portion 1022E, and a notch having a depth d ′ (<d) on the upper side of the hook portion 1022E. A portion 1022D ′ is provided. In the lifting member 1022 ′, the bottom side of the notch portion 1022 D of the hook portion 1022 A, the bottom side of the notch portion 1022 D ′ of the hook portion 1022 E, and the upper side of the hook portion 1022 B serve as abutting portions. The depth d ′ [mm] of the notch 1022D ′ is such that the straight line connecting these contact portions is a straight line inclined at an inclination angle θ with respect to the axial direction M of the arm metal 3 as shown in FIG. Is set to

上記実施の形態では、フック部１０２２Ａとフック部１０２２Ｂを一体的に形成しているが、フック部１０２２Ａとフック部１０２２Ｂを別部材にしてそれぞれ個別に蓋１０１Ｂの所定の位置に固定するようにしてもよい。 In the above embodiment, the hook portion 1022A and the hook portion 1022B are integrally formed. However, the hook portion 1022A and the hook portion 1022B are made separate members and are individually fixed at predetermined positions on the lid 101B. Also good.

上記実施の形態では、吊上げ部材１０２２のフック部１０２２Ａ，１０２２Ｂの向きを腕金３の軸方向Ｍに対して直交する向きにし、当該腕金３の下面の長手方向の２点で当接させる構成であったが、例えば、図９に示すように、腕金３の下面に長手方向に沿って線状に当接する構造の吊上げ部材１０２２”としてもよい。 In the above-described embodiment, the hooks 1022A and 1022B of the lifting member 1022 are oriented so as to be orthogonal to the axial direction M of the arm metal 3 and contacted at two points in the longitudinal direction of the lower surface of the arm metal 3. However, for example, as shown in FIG. 9, a lifting member 1022 ″ having a structure that linearly contacts the lower surface of the arm metal 3 along the longitudinal direction may be used.

図９に示す吊上げ部材１０２２”は、幅方向の寸法ｗが単調減少若しくは単調増加する帯状の板材の両端部を直角に屈曲させて両屈曲部をフック部１０２２Ａ，１０２２Ｂに対応するフック部１０２２Ａ’，１０２２Ｂ’とし、各フック部１０２２Ａ’，１０２２Ｂ’に吊上げ部材１０２２”の固定部１０２２Ｃ’を形成した部材を２個組み合わせたものである。各部材のフック部１０２２Ａ’，１０２２Ｂ’の上辺と、フック部１０２２Ａ’とフック部１０２２Ｂ’を連結する部分１０２２Ｆの上辺は、腕金３の下面に当接する部分である。 The lifting member 1022 ″ shown in FIG. 9 has hook portions 1022A ′ corresponding to the hook portions 1022A and 1022B by bending both end portions of the belt-like plate material whose width dimension monotonously decreases or increases monotonously at right angles. , 1022B ′, and two hook members 1022A ′, 1022B ′ are combined with two members formed with the fixing portion 1022C ′ of the lifting member 1022 ″. The upper sides of the hook portions 1022A ′ and 1022B ′ of each member and the upper side of the portion 1022F connecting the hook portions 1022A ′ and 1022B ′ are portions that contact the lower surface of the arm metal 3.

連結部分１０２２Ｆの幅寸法は、フック部１０２２Ａ’からフック部１０２２Ｂ’側に単調増加しているので、吊上げ部材１０２２”を腕金３の下面に当接させて取付部１０２を腕金３に取り付けると、吊上げ部材１０２２”が固定される蓋１０１Ｂの上面が腕金３の軸方向Ｍに対して所定の傾斜角θで傾斜することになる。 Since the width dimension of the connecting portion 1022F monotonously increases from the hook portion 1022A ′ to the hook portion 1022B ′, the lifting member 1022 ″ is brought into contact with the lower surface of the arm metal 3 to attach the attachment portion 102 to the arm metal 3. Then, the upper surface of the lid 101B to which the lifting member 1022 ″ is fixed is inclined at a predetermined inclination angle θ with respect to the axial direction M of the arm metal 3.

上記実施の形態では、開閉器１の蓋１０１Ｂの上面を長手方向に傾斜させていたが、開閉器１の蓋１０１Ｂの上面を傾斜させる方向は長手方向に限定されるものではない。例えば、開閉器１の蓋１０１Ｂの上面を幅方向に傾斜させるようにしてもよい。この場合は、例えば、図１０に示すように、支持部材１０２１の蓋１０１Ｂの上面における取付方向を９０度回転して、蓋１０１Ｂの上面の幅方向に取り付けてもよく、図１１に示すように、吊上げ部材１０２２のフック部１０２２Ａの上辺とフック部１０２２Ｂの上辺に形成した切欠部１０２２Ｄ”の底辺をそれぞれ傾斜角θで傾斜させてもよい。 In the above embodiment, the upper surface of the lid 101B of the switch 1 is inclined in the longitudinal direction. However, the direction in which the upper surface of the lid 101B of the switch 1 is inclined is not limited to the longitudinal direction. For example, the upper surface of the lid 101B of the switch 1 may be inclined in the width direction. In this case, for example, as shown in FIG. 10, the attachment direction of the support member 1021 on the upper surface of the lid 101B may be rotated by 90 degrees and attached in the width direction of the upper surface of the lid 101B, as shown in FIG. The top side of the hook part 1022A of the lifting member 1022 and the bottom side of the notch part 1022D ″ formed on the top side of the hook part 1022B may be inclined at an inclination angle θ.

上記実施の形態では、取付部１０２を蓋１０１Ｂの上面に垂直に取り付け、蓋１０１Ｂの上面から吊上げ部材１０２２のフック部１０２２Ａの上辺までの距離と、蓋１０１Ｂの上面から吊上げ部材１０２２のフック部１０２２Ｂの切欠部１０２２Ｄの底辺までの距離とを異ならせることによって、蓋１０１Ｂの上面を腕金３に対して傾斜角θで傾斜させていたが、図１２に示すように、蓋１０１Ｂの上面から吊上げ部材１０２２のフック部１０２２Ａ，フック部１０２２Ｂの上辺まで距離は同一にし、取付部１０２自体を傾斜角θで傾斜させて蓋１０１Ｂの上面に取り付けることによって蓋１０１Ｂの上面を腕金３に対して傾斜角θで傾斜させるようにしてもよい。 In the above embodiment, the attachment portion 102 is attached perpendicularly to the upper surface of the lid 101B, the distance from the upper surface of the lid 101B to the upper side of the hook portion 1022A of the lifting member 1022, and the hook portion 1022B of the lifting member 1022 from the upper surface of the lid 101B. The upper surface of the lid 101B was inclined at an inclination angle θ with respect to the arm metal 3 by making the distance to the bottom of the notch 1022D different from that of the notch 1022D. However, as shown in FIG. The upper distance of the hook part 1022A and the hook part 1022B of the member 1022 is the same, and the upper part of the cover 101B is inclined with respect to the arm metal 3 by attaching the attachment part 102 itself to the upper surface of the cover 101B with an inclination angle θ. You may make it incline by angle (theta).

図１２に示す取付部１０２’は、図１に示す取付部１０２に対して、吊上げ部材１０２２のフック部１０２２Ａの上辺に切欠部１０２２Ｄが設けられていない点が異なる。また、支持部材１０２１’が、蓋１０１Ｂの上面に対して支持部材１０２１’の上面が傾斜角θで傾斜するように、蓋１０１Ｂの上面に固定されている点が異なる。 The mounting portion 102 ′ shown in FIG. 12 is different from the mounting portion 102 shown in FIG. 1 in that a notch 1022 D is not provided on the upper side of the hook portion 1022 A of the lifting member 1022. Further, the support member 1021 'is fixed to the upper surface of the lid 101B so that the upper surface of the support member 1021' is inclined at an inclination angle θ with respect to the upper surface of the lid 101B.

図１２では、支持部材１０２１’の高さを左端側から右端側に単調に減少させている。すなわち、支持部材１０２１’のフック部１０２２Ａにおける高さＨ１’を支持部材１０２１’のフック部１０２２Ｂにおける高さＨ１よりも小さくするようにして、蓋１０１Ｂの上面からフック部１０２２Ａの腕金３の下面の当接位置までの距離（Ｈ１’＋Ｈ２）が蓋１０１Ｂの上面からフック部１０２２Ｂの腕金３の下面の当接位置までの距離（Ｈ１＋Ｈ２）よりも短くなるようにしている。これにより、取付部１０２で開閉器１を腕金３に取り付けると、蓋１０１Ｂの上面を腕金３に対して傾斜角θで傾斜させることができる。 In FIG. 12, the height of the support member 1021 'is monotonously decreased from the left end side to the right end side. That is, the height H1 ′ at the hook portion 1022A of the support member 1021 ′ is made smaller than the height H1 at the hook portion 1022B of the support member 1021 ′, and the lower surface of the arm metal 3 of the hook portion 1022A from the upper surface of the lid 101B. The distance (H1 ′ + H2) to the abutting position is shorter than the distance (H1 + H2) from the upper surface of the lid 101B to the abutting position of the lower surface of the arm metal 3 of the hook portion 1022B. Thus, when the switch 1 is attached to the arm metal 3 by the attachment portion 102, the upper surface of the lid 101B can be inclined with respect to the arm metal 3 at an inclination angle θ.

なお、図１において、例えば、支持部材１０２１の固定部１０２１Ｂの右端部側にある締結点と蓋１０１Ｂの上面の間に挿入するワッシャの厚みと、固定部１０２１Ｂの左端部側にある締結点と蓋１０１Ｂの上面の間に挿入するワッシャの厚みを異ならせることにより、支持部材１０２１の上面を蓋１０１Ｂの上面に対して傾斜角θで傾斜させるようにしてもよい。或いは、厚みの異なるワッシャを用いるのに代えて、同一厚みのワッシャの使用数を異ならせて支持部材１０２１の上面を蓋１０１Ｂの上面に対して傾斜角θで傾斜させるようにしてもよい。 In FIG. 1, for example, the thickness of the washer inserted between the fastening point on the right end side of the fixing portion 1021B of the support member 1021 and the upper surface of the lid 101B, and the fastening point on the left end side of the fixing portion 1021B. The upper surface of the support member 1021 may be inclined at an inclination angle θ with respect to the upper surface of the lid 101B by varying the thickness of the washer inserted between the upper surfaces of the lid 101B. Alternatively, instead of using washers with different thicknesses, the upper surface of the support member 1021 may be inclined at an inclination angle θ with respect to the upper surface of the lid 101B by using different numbers of washers with the same thickness.

すなわち、支持部材１０２１の右端側の固定部１０２１Ｂの蓋１０１Ｂの上面からの高さを、支持部材１０２１の左端側の固定部１０２１Ｂの蓋１０１Ｂの上面からの高さよりも高くして、支持部材１０２１の上面を蓋１０１Ｂの上面に対して傾斜角θで傾斜させるようにしてもよい。 That is, the height of the fixing portion 1021B on the right end side of the support member 1021 from the upper surface of the lid 101B is made higher than the height of the fixing portion 1021B on the left end side of the support member 1021 from the upper surface of the lid 101B. May be inclined at an inclination angle θ with respect to the upper surface of the lid 101B.
