Embodiment Construction

[0020] Such as Figure 1-Figure 3 As shown, the safety composite cable includes a cable outer layer composed of more than one protective sheath 8 spliced ​​together, and the middle of the protective sheath 8 has a cable protection cavity 7, and the cable core wire 9 is arranged in the cable protection cavity 7. One end of each protective sleeve 8 is provided with an assembly convex portion 11, and the assembly convex portion 11 on the adjacent side is loaded into the protective sleeve 8 on one side and sealed;

[0021] The end face of each protective cover 8 is provided with more than one limiting through hole around the circumferential direction of the protective cover. An elastic inflatable belt 5 with the same length as the outer layer of the cable is fixed on the outside of each section of the protective cover 8, and a gas storage ring 1 is fixed. The inner ring of the gas storage ring 1 is provided with more than one air guide tube 4, and more than one One end of the air...

Abstract

The invention discloses a safe composite cable, which comprises a cable sheath layer consisting of more than one protective sleeve, wherein each protective sleeve has a cable protection cavity thereinat the middle; a cable core is arranged in the cable protection cavities; one end of each protection sleeve is provided with an assembling convex portion; and the assembling convex portions on the adjacent sides are assembled and sealed in the protective sleeve at the same side. The composite cable of the invention has very good tensile resistance and can fill a hole by means of the expansion ofan elastic inflatable belt when one protective sleeve has the hole in order to prevent the external moisture from entering and causing a short circuit, thereby increasing the safety of the cable.

Description

technical field [0001] The invention relates to a cable, in particular to a safety composite cable. Background technique [0002] With the rapid development of society, cable, as an important product of electric energy or signal transmission, has also been developed rapidly and effectively. The current cable structure is relatively simple, and the cable core wire is generally protected by an external cable protective layer, while the cable protective layer The strength of the cable is low. After a long time of use, it is easy to cause holes in the cable protective layer due to aging or other external factors, and then directly expose the inner core wire, and the external moisture will enter the inside, causing the cable to short circuit or the internal core wire to break. In addition, cables are required to have good tensile strength in many occasions. The current one-piece cable has no buffer structure when it is pulled, which makes the cable easy to be damaged due to pulli...
