Description
Technical field
The utility model relates to wire and cable fields, and in particular to a kind of cable.
Background technique
Cable is widely used in every field as a kind of electric power, information transmission equipment.Some cables can be in it is exposed
In outer working environment, it is easy to be oppressed or hit and occur damaging, fracture.
Utility model content
The utility model aim is to be to provide a kind of cable that resistance to mechanical is hit, to solve at least one above-mentioned skill
Art problem.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of cable that resistance to mechanical is hit, including a cable, the cable include sheath and are embedded in the sheath
Cable core, which is characterized in that further include three sleeves, respectively cross section is that circular outer sleeve, middle sleeve and cross section are
Three seamed edges of the inner sleeve of equilateral triangle, the inner sleeve are against on the inner wall of the middle sleeve, and the cable core setting exists
In the chamber that the inner sleeve and middle sleeve are formed；
The outer sleeve and middle sleeve are sleeves made of metal hose, and the inner sleeve is inner sleeve made of rubber-plastics material
Three seamed edges of cylinder, the inner sleeve are equipped with transition arc.
The utility model adds three sleeves, and inner sleeve is designed as triangle cylinder, and stability is strong, when being hit,
Three angles can provide good impact resistance, effectively support middle sleeve, protect cable core.In addition, being made of metal hose
Sleeve can reinforce the protection to cable and play shielding action.
A toroidal cavity can also be formed between the middle sleeve and the outer sleeve, in the cavity along the circumferential direction
3 returning springs of even setting, filled rubber in the cavity.It is equipped with returning spring between outer sleeve and middle sleeve and is filled with rubber
Glue obtains buffer function with fine.
Fire retardant is inserted in gap in chamber where the cable core.
The surface of the returning spring is coated with fire resistant coating.
It is wound with water blocking tape on the outside of the outer sleeve, the sheath is set in outside the water blocking tape.
The sheath is sheath made of Ceramic silicon rubber.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
