本発明は溶接部に大電流を導くだめの抵抗溶接機用二次
ケーブルに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a secondary cable for a resistance welding machine that conducts a large current to a welding part.
従来の抵抗溶接機用二次ケーブルでは隣接ケーブルや治
具等との接触を防止するためにケーブルをゴムホース等
のカバーで被覆するように構成されていた。Conventional secondary cables for resistance welding machines are constructed so that the cable is covered with a cover such as a rubber hose to prevent contact with adjacent cables, jigs, etc.
しかしながら、このような構成からなる抵抗溶接機用二

付近が曲り易く、端子付近で集中的に素線切れが発生す
るという不具合があった。However, in a secondary cable for a resistance welding machine with such a configuration, heat radiation from the cable is blocked by the cable cover, which deteriorates heat radiation efficiency and causes wire breakage. Even if the wire is damaged, it is not visible from the outside, and when the cable is bent, the vicinity of both terminals tends to bend, and there is a problem in that wire breakage occurs concentratedly in the vicinity of the terminal.
本発明の目的は上記従来技術の欠点を解消し。The object of the present invention is to overcome the drawbacks of the prior art mentioned above.

The figure shows the configuration of an embodiment of a secondary cable for a resistance welding machine according to the present invention, and in the figure, 1 is a cable;
2 is a terminal; 3 is formed of an insulating material such as resin in the shape of a coil spring at a constant pitch over the entire length of the cable;
In a conventional secondary cable for a welding machine that uses a rubber hose or the like as a cable cover, which may be a cable cover inserted over the cable 1, when the cable 1 is installed in the state shown in Fig. 2, the cable 1 is connected to the solid line (arrow A). ), the cable bends near both terminals (arrows I, I), strand breakage occurs at these parts, and cable breakage is concentrated near these terminals.

。On the other hand, when the cable is covered with the cable cover 3 formed in the shape of a coil spring as in this embodiment, the bending of the cable 1 near the terminal 2 is relaxed, as shown by the dotted line in FIG. 2 (arrow B). and averaged. For this reason, it is possible to prevent strand breaks from concentrating in a specific location of the Kerpul 1, and to extend the life of the cable. Further, according to this embodiment, the heat dissipation from the cable is improved, and damage to the cable can be easily detected from the outside.
次に第3図に本発明の他の実施例の構成を示す。Next, FIG. 3 shows the configuration of another embodiment of the present invention.
同図に示す如く本実施例ではケーブルカバー13を、ケ
ーブル1の端子2.2の方向に行くKつれて漸次、密と
ガるようにコイルスプリング状に形成したものである。As shown in the figure, in this embodiment, the cable cover 13 is formed in the shape of a coil spring so that it gradually tightens in the direction of the terminal 2.2 of the cable 1.
このように構成することによりケーブル1取付時にケー
ブル1の全長にわたって屈曲率を平均化させることがで

の長寿命化が図れる。By configuring it in this way, it is possible to average the bending ratio over the entire length of the cable 1 when the cable 1 is attached, and it is possible to avoid concentration of stress on a specific part of the cable 1, as shown in Figure 1. The lifespan can be further extended compared to the embodiment.

てもよい。Next, FIG. 4 shows another embodiment of the present invention. In this embodiment, we focused on the fact that the vicinity of the terminals of the cable 1 is excessively bent when the cable 1 is installed, and stress is concentrated in this part, so we designed a cable cover with a constant coil pitch only in the vicinity of both terminals 2 and 2 of the cable 1. 23 and 23 are extrapolated. In addition, when inserting a cable cover only near both terminals 2 and 2 of the cable 1, as shown in FIG. A cover 33 may also be formed.

構成してもよい。In addition, in the embodiment shown in FIGS. 4 and 5, the case where the cable cover is attached near both terminals of the cable has been explained, but the cable cover may be attached only near one terminal depending on the installation state of the cable. It may be configured as follows. Further, as shown in FIGS. 9 and 10, the coil diameter of the cable cover 63% 73 may be configured to gradually become smaller as it goes from the center of the cable 1 toward both terminals 2.2.

れなどの品質トラブルをも解消することができる。As explained above, in the present invention, a secondary cable for a resistance welding machine that conducts a large current to a welding part is configured so that a cable cover formed in the shape of a coil spring is fitted over the cable. Heat accumulation caused by the cover, which was a problem in the past, is eliminated, stress concentration near the cable terminals is alleviated, and the life of the secondary cable for resistance welding machines can be extended. In addition, since the cable can be observed from the outside, damage can be easily discovered, improving maintainability and eliminating quality problems such as spot separation.
