The utility model provides a cable joint, which comprises a shell and a conductive stress cone, a first end of the shell is provided with a first inlet, a second end of the shell is provided with a second inlet, a first cable penetrates through the first inlet to enter the shell, a second cable penetrates through the second inlet to enter the shell, and the first cable and the second cable are communicated in the shell. The conductive stress cones are arranged in the shell and comprise the first conductive stress cone and the second conductive stress cone, the shielding layer fracture of the first cable is located at the first conductive stress cone, and the shielding layer fracture of the second cable is located at the second conductive stress cone. According to the technical scheme, theproblem that in the prior art, a large amount of time needs to be consumed when a cable connector is used for repairing a cable is effectively solved.
