Problems solved by technology

[0003] In the prior art, the waterproof measures for the cable joints are mainly achieved by wrapping waterproof tapes on the inner sheath and outer sheath of the cable respectively. On the one hand, loose waterproof tapes may lead to waterproof failure, resulting in short-circuit and other risks. When the joint part of the cable is squeezed by external force, the waterproof tape cannot protect the joint part

Abstract

The invention relates to the technical field of cable connection, and discloses a cable joint protection device. The cable joint protection device is used for protecting joint parts of two cables andcomprises a first hard shell, a second hard shell and two welding sections, and the first hard shell is used for being arranged on one cable in a sleeving mode; the second hard shell is used for beingarranged on the other cable in a sleeving mode, and the second hard shell and the first hard shell are connected in a sealed mode to form a containing space for containing the joint part of the cable; the two welding sections are connected to the ends, deviating from each other, of the first hard shell and the second hard shell respectively, and the welding sections can be connected with an outersheath of the cable in a welding mode. The cable joint protection device is simple in structure, has external extrusion resistance and is good in waterproof effect.

Description

technical field [0001] The invention relates to the technical field of cable connection, in particular to a cable joint protection device. Background technique [0002] The cable joint is the weakest part of the cable, especially when the joint is in a harsh environment such as humidity and acidic soil, in order to ensure the service life of the entire cable, it needs to be specially protected against waterproofing and extrusion. [0003] In the prior art, the waterproof measures for the cable joints are mainly realized by wrapping waterproof tapes on the inner sheath and outer sheath of the cable respectively. On the one hand, loose waterproof tapes may lead to waterproof failure, resulting in short-circuit and other risks. When the joint of the cable is squeezed by external force, the waterproof tape cannot protect the joint. [0004] Therefore, there is an urgent need to invent a cable joint protection device to solve the above problems. Contents of the invention [0...
