ルである。Structure of conventional example and its problems Figure 1 shows an example of a conventional welding torch and the approximate position of the cable protection tube. The vertical direction in the drawing is the direction perpendicular to the welding torch, and the direction perpendicular to the drawing is the horizontal direction. The cable protection tube 5 is a rubber-like reinforcing material provided to prevent the torch cable 2 from being severed due to severe bending motion at the portion exposed from the torch holder 4. It covers the outer periphery and is partially housed within the torch holder 4. 1 is a torch body, 3 is a connector, and 6 is a nozzle.

により制約を受け、小形化を困難にしていた。 FIG. 2 shows the cross-sectional shapes of a conventional cable protection tube and torch holder. In Figure 2, the cable protection tube 5 is often a cylindrical tube with circular inner and outer diameters, but the torch holder 4 is designed to be used in the vertical direction of the welding torch for ease of grip by the operator. It is desirable to have a cross-sectional shape that is long and short in the horizontal direction. If a cable protection tube 5 with a circular cross-sectional shape is used as described above, the horizontal dimension of the torch holder 4 will be limited by the size of the cable protection tube 5. , which made downsizing difficult.
発明の目的
本発明はトーチホルダー断面の小形化をはかり
つつ、ケーブルの断線保護に最も有効な形状をし
たケーブル保護筒を有する溶接用トーチを提供す
るものである。OBJECTS OF THE INVENTION The present invention provides a welding torch which has a cable protection tube having a shape most effective for protecting the cable from disconnection while reducing the cross section of the torch holder.

様な断面形状とし、楕円または小判形の長径方向
を鉛直方向に一致させたものである。Structure of the Invention In order to achieve this object, the present invention provides a cable protection tube with a circular inner circumference, an oval or oval outer circumference, and a uniform cross-sectional shape with a projection on a part of the outer circumference. , an ellipse or an oval shape with the major axis direction aligned with the vertical direction.
実施例の説明
第３図〜第５図に本発明によるケーブル保護筒
の断面形状を示す。DESCRIPTION OF EMBODIMENTS FIGS. 3 to 5 show cross-sectional shapes of cable protection tubes according to the present invention.

能である。 In FIG. 3, the upper and lower sides in the vertical direction have the same wall thickness, and in FIG. 4, the lower side is the thicker part. In FIGS. 3 and 4, 7 is a protrusion provided on the outer periphery of the ellipse in the major axis direction, and can be easily molded by giving the extrusion molding die a suitable shape in advance.

ーチケーブル２を内包する関係上、必然的に円で

楕円とすると、楕円の長径方向には厚肉となり、
短径方向には薄肉となる。 That is, the inner circumference of the cable protection tube 5 is circular, and the outer circumference is oval or oval. The inner shape must necessarily be a circle in order to enclose the torch cable 2, but if the outer shape is an ellipse compared to the inner circle, the ellipse will have a thick wall in the long axis direction.
It becomes thinner in the short axis direction.

の長径方向、短径方向を組立作業時に簡単に識別
できるよう、外周部の特定箇所に突起７を設け、
組立作業時の目印とする。 On the other hand, the torch cable 2 hangs down in the vertical direction due to the welding work posture, and is subjected to the most severe bending motion in that direction. In order to reduce the horizontal dimension of the torch holder, the thin part of the cable protection tube (the short diameter direction of the ellipse) is oriented horizontally. Further, protrusions 7 are provided at specific locations on the outer periphery so that the long axis direction and short axis direction of the cable protection tube can be easily identified during assembly work,
Use as a landmark during assembly work.
発明の効果

きる。(1) Due to the effect of the elliptical shape, it is possible to effectively prevent the torch cable from breaking due to bending, and to reduce the horizontal dimension of the torch holder.
(2) 外周部の突起により、楕円の方向が簡単にわ
かり、組立作業性が良い。(2) The protrusion on the outer periphery makes it easy to see the direction of the ellipse, making assembly work easier.
