Abstract
The utility model relates to a tubing coupling for protecting a cable. The tubing coupling for protecting the cable is used for connecting an end of an upper section tubing and an end of a lower section tubing from the outer side, and is provided with an inner threaded hole which is used for connecting a tubing in a screw-joint mode. A perforating groove which is used for containing the cable is formed in the outer side wall of the tubing coupling for protecting the cable in the axial direction. Due to the facts that a corresponding section of the cable is arranged in the groove of the tubing coupling in a contained mode, and when the cable goes down a well along with the tubing, the corresponding section of the cable cannot be abraded, the tubing coupling for protecting the cable can have the effect of connecting the upper section tubing and the lower section tubing and the effect of protecting the cable, and meanwhile other components do not need to be installed outside the tubing coupling. Compared with a cable protector in the prior art, the tubing coupling for protecting the cable has the advantages of being low in processing cost, free of secondary installation and the like. Due to the fact that the tubing coupling for protecting the cable cannot be influenced by adherence of crude oil, the protection effect on the cable of the tubing coupling for protecting the cable is continuous and stable.
