[0007] Further, mounting lugs are fixed on the outer periphery of the shell.

[0008] Further, a leakage detector is arranged on the outer periphery of the reinforcing ring, and the leakage detector is electrically connected with an external alarm system.

[0009] Further, the material of the shell is epoxy resin.

[0010] Compared with the prior art, the utility model has the advantages of:

[0011] 1、The utility model discloses a diameter of reinforcing ring can be adjusted through screw rod, and the diameter of butt joint device can be changed according to the diameter of cable, and different specifications of cable can be adapted.

[0012] 2、The utility model discloses a arc spring is in the state of contraction under normal condition, when moving inwards screw rod, screw rod drives telescopic ring to be close to cable, and telescopic ring and arc spring contract to clamp the cable after butt joint, if the diameter of cable is thick, then can move screw rod outward, and screw rod drives telescopic ring to expand when moving, and arc spring expands simultaneously, until the inner diameter of reinforcing ring matches the diameter of cable.

[0013] 3、The utility model discloses a shell is made of epoxy resin, and epoxy resin is insulating material, has excellent insulating performance and waterproof and explosion -proof ability, and epoxy resin is transparent material, and the state of internal cable can be directly observed through the shell.
