本考案は冷却ケーブルの端末構造の改良に関
し、特に、スポツト溶接機用水冷ケーブルの端末
として有用なものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement in the terminal structure of a cooling cable, and is particularly useful as a terminal of a water-cooled cable for a spot welding machine.
先行技術と問題点
溶接機の給電用ケーブルには、通常、水冷ケー
ブルを用い、そのケーブル端末には電力を給電
し、かつ冷却水を導通するための端子を取付けて
いる。Prior Art and Problems A water-cooled cable is normally used as a power supply cable for a welding machine, and a terminal for supplying power and conducting cooling water is attached to the end of the cable.
ところで、ロボツト溶接機の場合、溶接ガンが

子に接続せるケーブル導体端部が苛酷な繰り返え
し曲げモーメント並びに捩れモーメントを受ける
ので該導体端部が短期に破断し易い。 By the way, in the case of a robot welding machine, the welding gun exhibits very complicated behavior such as vertical, horizontal, and twisting, and the end of the cable conductor connected to the terminal is subjected to severe repeated bending and twisting moments. The conductor ends tend to break in a short period of time.
而るに、従来、かかる破断があつた場合、端子
金具の再使用が困難であり、従つて、端子金具の
実際の使用可能期間が短かく、コスト的に不利で
あつた。 However, in the past, when such a breakage occurred, it was difficult to reuse the terminal fitting, and therefore the actual usable period of the terminal fitting was short, which was disadvantageous in terms of cost.
考案の目的
本考案の目的は端子金具の再使用が可能な冷却
ケーブルの端末構造を提供することにある。Purpose of the invention The purpose of the invention is to provide a cooling cable terminal structure in which the terminal fittings can be reused.

Insert the end of the cover crimped conductor into the sleeve of the terminal fitting with the hole, compress the sleeve with a retaining ring that does not cover the tip of the slit, and tie the hose end of the cooling cable to the terminal fitting. This configuration is characterized by the following.
実施例の説明 以下、図面により本考案を説明する。Description of examples The present invention will be explained below with reference to the drawings.

Thus, the sleeve portion 2 has a divided structure as shown in FIG. 11 is a locking tooth provided on the outer surface of the body 1;
12 is a battledore portion provided at the other end of the body portion 1.

金具Ａの胴部１に挿着してある。 In FIG. 3, W is a cooling cable, a conductor 4 is inserted into an insulator hose 30, and the space inside the hose is used as a cooling water passage. 41 is the end of the cable conductor, to which a tubular metal cover with a bell mouth is crimped. A is the above-mentioned terminal fitting, and the metal cover crimp conductor end is inserted into the sleeve portion 2. 6 is a retaining ring, which is compressed into the sleeve portion 2. The width of the retaining ring 6 is made relatively narrow so that the tip end 210 of the slit 21 is not covered by the retaining ring 6. B is the end of the hose, which is inserted into the body 1 of the terminal fitting A.

具合よく確保できる。 If the retaining ring 6 is cut in the above manner, the clamping force of the sleeve part 2 itself is extremely small due to the presence of the slits 21, so that the conductor end can be easily removed. Therefore, if the conductor end breaks, the terminal fitting A can be easily removed from the cable terminal without distorting the fitting itself, and the terminal fitting can be reused. In addition, since the metal cover 5 is crimped to the conductor end, it is possible to prevent the conductor strands of the conductor end 41 from being caught in the slits 21, ... of the sleeve part 2, and therefore prevent the compression of the retaining ring 6. Therefore, the diameter of the sleeve portion 2 can be easily reduced by narrowing the slits 21, so that the conductor end portion can be firmly fixed. Furthermore, the slit tip 210 of the sleeve portion communicates with the cooling water passage in the terminal and the cooling water passage in the hose, so that the circulation of cooling water can be ensured properly.

端子金具は再使用でき、コスト的に有利である。Effects of the invention The terminal structure of the cooling cable according to the invention is as described above, and the terminal fittings can be reused, and the fixing strength of the conductor ends and the flowability of the cooling water can be ensured well. Therefore, even if the cable conductor is broken, the terminal fitting can be reused, which is advantageous in terms of cost.
