Description

Technical Field

[0001] The utility model specifically relates to the technical field of cable sheaths, in particular to a cable sheath with the function of preventing cables from freezing and cracking. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, primarily controlling installations, connecting devices, and transmitting power. They are a common and indispensable part of everyday life. However, because cables carry electrical current, they require special care during installation.

[0003] Chinese Utility Model Publication No. CN 220234039 U discloses a cable sheath and a cable device. The cable sheath includes a first tightening portion and a second tightening portion of identical structure. The first tightening portion has an arcuate receiving groove. The arcuate receiving groove is provided with fixing portions on both side edges along its circumference, and an anti-slip pad is provided on the inner wall of the arcuate receiving groove. The first tightening portion and the second tightening portion are arranged such that the arcuate receiving groove of the first tightening portion and the arcuate receiving groove of the second tightening portion face each other. The fixing portion of the first tightening portion and the fixing portion of the second tightening portion are fixedly connected by a connecting member. The cable is tightened in a space enclosed by the arcuate receiving groove of the first tightening portion, the arcuate receiving groove of the second tightening portion, and the connecting member.

[0004] The above-mentioned cable sheath and cable device fix the cable through the tightening part and cannot be used in a fully enclosed manner. When the external temperature is too low, the protective layer on the outside of the cable will be frozen and cracked, causing a safety hazard. For this reason, we provide a cable sheath with anti-freeze cracking function. The cable is supported by a tin foil tube. The opening on the tin foil tube can allow the temperature generated by the heating tape to enter the inside, thereby ensuring that the outer protective layer of the cable will not be frozen and cracked, effectively compensating for the above-mentioned problem. Utility Model Content

[0008] As a further technical solution of the present invention, one end of the corrugated pipe is provided with a thread for facilitating threaded connection of a mounting head, and the mounting head is provided with a circular hole for facilitating insertion of the heating tape.

[0009] As a further technical solution of the present invention, one end of the heating tape is electrically connected to a terminal block, and the terminal block is fixed to the mounting head by bolts.

[0010] As a further technical solution of the present invention, the heating tape is clamped on the heating tape buckle, and the heating tape buckle is welded to the inner wall of the rubber tube.
