【産業上の利用分野】[Industrial applications]

本考案は、プレハブ型電力接続箱を組み立てる際に用いるストレスコーン装着 位置確認用ノギスに関する。 The present invention relates to a caliper for confirming the position of a stress cone used when assembling a prefabricated power junction box.

【従来技術】[Prior art]

従来、絶縁ブロックとストレスコーンから構成されるプレハブ型電力ケーブル 接続箱の組立は次のような手順で行われる。即ち、 1)図3に示すように、絶縁ブロック3とストレスコーン4をケーブル1へ挿入 し、 2)導体接続管2を用いて導体を接続した後、絶縁ブロック3を導体接続管2へ 取りつける。 3)次いで、絶縁ブロック3内側へストレスコーン4をこれ以上移動しない状態 まで押し込む。 4)次いで、絶縁ブロック3とストレスコーン4の相対位置を示す寸法L0 を測 定し、管理した後に押し金具5、スプリング6を絶縁箱(図示せず)に装着し、 ストレスコーン4を絶縁ブロック3内面に圧接する。 絶縁ブロック3とストレスコーン4の相対位置寸法L0 の測定は、例えば図4 に示すように、ストレスコーン4の端部にスケール7を立て、金尺あるいはノギ スでL0 を測定する。Conventionally, the assembly of a prefabricated type power cable junction box composed of an insulating block and a stress cone is performed by the following procedure. That is, 1) insert the insulating block 3 and the stress cone 4 into the cable 1 as shown in FIG. 3, and 2) connect the conductor using the conductor connecting pipe 2, and then attach the insulating block 3 to the conductor connecting pipe 2. . 3) Next, push the stress cone 4 into the insulating block 3 until it does not move any further. 4) Next, the dimension L 0 indicating the relative position between the insulating block 3 and the stress cone 4 is measured and managed, and then the pressing metal fitting 5 and the spring 6 are attached to an insulating box (not shown) to insulate the stress cone 4 Press contact with the inner surface of the block 3. The relative position dimension L 0 between the insulating block 3 and the stress cone 4 is measured by, for example, as shown in FIG. 4, setting a scale 7 at the end of the stress cone 4 and measuring L 0 with a metal scale or a caliper.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上記の方法では測定が不安定なため、正確な絶縁ブロックとス トレスコーンの相対位置寸法L0 を測定することができないという問題があった 。 さらに、従来のノギスをそのまま使用して寸法L0 を測定することはできない 。即ち、図5に示すように、ノギス8の本尺ジョウ9の外側測定面10の相対す る面11を絶縁ブロック3の端面に当てがい、バーニアジョウ12の外側測定面 13をストレスコーン4の端面に当てがおうとすると、本尺ジョウ9の先端側が ストレスコーン4に当たり、測定は不可能である。また、本尺ジョウ9が短く、 本尺ジョウ9の先端側がストレスコーン4に当たらなくても、測定できる寸法は L1 であり、求める寸法L0 とはならない。However, the above method has a problem that the relative position dimension L 0 between the insulating block and the stress cone cannot be accurately measured because the measurement is unstable. Furthermore, the dimension L 0 cannot be measured using the conventional calipers as they are. That is, as shown in FIG. 5, the opposite surface 11 of the outer measuring surface 10 of the main scale jaw 9 of the caliper 8 is applied to the end surface of the insulating block 3, and the outer measuring surface 13 of the vernier jaw 12 is applied to the stress cone 4. When trying to apply it to the end face, the tip side of the main scale jaw 9 hits the stress cone 4, and measurement is impossible. Even if the main scale jaw 9 is short and the tip side of the main scale jaw 9 does not hit the stress cone 4, the measurable dimension is L 1 and the required dimension L 0 is not obtained.

【課題を解決するための手段と作用】[Means and actions for solving the problem]

本考案は上記問題点を解決したストレスコーン装着位置確認用ノギスを提供す るもので、本尺ジョウの外側測定面と外側測定面に相対する面が平行であるノギ スにおいて、本尺ジョウの先端側部分を切断し、該部分の外側測定面あるいはそ の相対する面をバーニアジョウ先端側部分の外側測定面に密着、固定させたこと を特徴とするものである。 本考案は、物体の外側寸法を測定するノギスを改造したものである。本考案の ノギスの本尺ジョウの外側測定面に相対する面を絶縁ブロックの端面に当てがい 、バーニアジョウ先端側部分の外側測定面に密着、固定させた本尺ジョウの先端 側部分をストレスコーンの端面に当てがう。そうすると、バーニアジョウ先端側 部分の外側測定面の位置は本尺ジョウの幅だけずれるため、絶縁ブロックとスト レスコーンの相対位置を測定することができる。 The present invention provides a caliper for confirming the position of the stress cone mounting that solves the above-mentioned problems, and in a caliper in which the outer measurement surface of the main scale jaw and the surface facing the outer measurement surface are parallel, The tip side portion is cut, and the outer measuring surface of the portion or its opposing surface is brought into close contact with and fixed to the outer measuring surface of the vernier jaw tip side portion. The present invention is a modification of a caliper that measures the outer dimension of an object. The surface of the vernier caliper of the present invention facing the outer measurement surface of the main scale jaw is applied to the end face of the insulating block, and the tip of the main scale jaw is fixed to the outer measurement surface of the vernier jaw tip side. Apply to the end face of. Then, the position of the outer measuring surface at the tip of the vernier jaw is displaced by the width of the main scale jaw, so the relative position of the insulating block and the stress cone can be measured.

【実施例】【Example】

以下、図面に示した実施例に基づいて本考案を詳細に説明する。 図1は本考案にかかるストレスコーン装着位置確認用ノギスの一実施例の側面 図である。本実施例は、本尺ジョウ21の外側測定面22と外側測定面22に相 対する面23が平行であるノギス24を利用し、本尺ジョウ21の先端側部分2 5(点線部分)を切断し、この先端側部分25の外側測定面22あるいは外側測 定面22に相対する面23をバーニアジョウ26の先端部分の外側測定面27に 密着、固定させたものである。図2は、本実施例のストレスコーン装着位置確認 用ノギスを用いた絶縁ブロックとストレスコーンの相対位置の測定方法の説明図 である。ケーブル1に装着された絶縁ブロック3の端面にノギス24の先端が切 断された本尺ジョウ21の外側測定面22に相対する面23を当てがい、ストレ スコーン4の端面にバーニアジョウ26の先端部分の外側測定面27に密着、固 定された本尺ジョウ21の先端側部分25を当てがう。この状態での測定値(外 側測定面22と27の間隔)をL2 とすると、外側測定面22は絶縁ブロック3 の端面より本尺ジョウ21の幅Wだけ右側にずれ、外側測定面27はストレスコ ーン4の端面より同じくWだけ右側にずれている。したがって、L2 は絶縁ブロ ック3とストレスコーン4の端面間隔L0 に等しくなり、絶縁ブロック3とスト レスコーン4の相対位置を測定することができる。Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a side view of an embodiment of a caliper for confirming a stress cone mounting position according to the present invention. In this embodiment, a caliper 24 having an outer measurement surface 22 of the main scale jaw 21 and a surface 23 corresponding to the outer measurement surface 22 is parallel to each other, and a tip side portion 25 (dotted line portion) of the main scale jaw 21 is cut. The outer measuring surface 22 of the tip side portion 25 or the surface 23 facing the outer measuring surface 22 is closely fixed to the outer measuring surface 27 of the tip portion of the vernier jaw 26. FIG. 2 is an explanatory diagram of a method for measuring the relative position between the insulating block and the stress cone using the caliper for confirming the stress cone mounting position of the present embodiment. The end 23 of the vernier caliper 24 is attached to the end face of the insulating block 3 attached to the cable 1, the face 23 facing the outer measuring face 22 of the main scale jaw 21 is applied, and the end of the vernier jaw 26 is attached to the end face of the stress cone 4. The tip side portion 25 of the main scale jaw 21 that is firmly fixed to the outer measurement surface 27 of the portion is applied. Assuming that the measured value in this state (the distance between the outer measuring surfaces 22 and 27) is L 2 , the outer measuring surface 22 is displaced to the right by the width W of the main scale jaw 21 from the end surface of the insulating block 3, and the outer measuring surface 27 Is also offset to the right by W from the end face of stress cone 4. Therefore, L 2 becomes equal to the end face distance L 0 between the insulating block 3 and the stress cone 4, and the relative position between the insulating block 3 and the stress cone 4 can be measured.
