Description

Technical Field

[0001] The utility model embodiment relates to the technical field of couplings, and in particular to an eccentric cable crossing coupling. Background Art

[0002] During production or testing downhole, it is necessary to connect cables from the wellhead to the downhole. Especially when the cables need to be lifted and lowered together with the pipe string, in order to avoid friction and collision between the cables and the casing, cable couplings are often used to fix the cables and the oil pipe and protect them. For example, as shown in the cable coupling with Chinese patent application number CN201220024037.4, the cable is in a vertical cable crossing groove and is protected by the cable sheath. The cable does not contact the inner wall of the casing.

[0003] However, in order to ensure reliable and stable connection between the coupling and the cable, a protective device is required to press the cable, and an installation tool is used to connect the protective device and the coupling together. Therefore, installation tools such as screwdrivers or wrenches need to be used repeatedly for fixing and disassembly. The operation is complicated, time-consuming, labor-intensive, inefficient, and parts are easily lost, which adds hidden dangers to on-site work. Utility Model Content
