Description
Technical field
The utility model is related to technical field of cables, specifically a kind of anti-fracture cable.
Background technology
Cable is not having after the situation that will appear fracture under the effect of external force, especially high voltage cable fracture is used for a long time
There are security risk in the case of on-call maintenance, current cable bears that external force is limited, and the protective layer on the outside of cable core has bullet
Property, the conductor when trace of fracture is not often seen on the outside of cable in cable core has been damaged.
Utility model content
The utility model provides one kind and cable core can be protected to solve the above-mentioned problems, can be in certain journey
The anti-fracture cable that cable core is damaged is effectively prevent under degree.
The utility model is achieved through the following technical solutions in order to achieve the above object：
1st, the utility model is a kind of anti-fracture cable, and including cable core, several cable core outer layers are provided with insulating layer,
Insulating layer outer layer is provided with thermal insulation layer, elastomeric plastics are provided on the outside of thermal insulation layer, is set on the outside of interior elastomeric plastics
There is anti-fracture structure, the both sides that anti-fracture structure includes being arranged on the outside of interior elastomeric plastics are provided with several arc panels, same
Each two adjacent arc panel in side is connected by spring, and both sides are both provided with several fixing ports, upper elastic piece above and below arc panel
And lower elastic piece is separately positioned on the top and bottom between two arc panels, the both ends of upper elastic piece and lower elastic piece, which are buckled in, to be set
It puts and in corresponding fixing port, outer elastomeric plastics is provided on the outside of anti-fracture structure on two arc panels, outside elasticity modeling
Fireprotection layer is provided on the bed of material, external protection is provided on the outside of fireprotection layer.
Further improvement of the utility model is：Cable core is by several copper conductors and is wrapped on the outside of several copper conductors
Insulate inner cladding.
2nd, further improvement of the utility model is：Arc panel includes the stay hook of intermediate male part and upper and lower ends,
It is provided with arc portion in the fixation with fixing port between intermediate male part and stay hook, upper elastic piece and lower elastic piece both sides
Hook portion is used cooperatively in stay hook.
The beneficial effects of the utility model are：The utility model is in external force by upper elastic piece and lower elastic piece and arc panel
External force is disperseed, cable core is protected, anti-fracture structure can limit the stretching of cable core, prevent cable core from stretching
Impaired situation, the fireprotection layer that outer elastomeric plastics outside is set can prevent external burning things which may cause a fire disaster from being caused to cable to a certain extent
It influences.
The utility model is simple in structure, reasonable design, can effectively prevent cable core under external force due to stretching and
Impaired or fracture.
Description of the drawings

Interior 4 outside of elastomeric plastics is provided with anti-fracture structure, and anti-fracture structure includes being arranged on the both sides in interior 4 outside of elastomeric plastics
Be provided with several arc panels 5, each two adjacent arc panel 5 in the same side is connected by spring 6, arc panel about 5 both sides it is equal
Several fixing ports are provided with, upper elastic piece and lower elastic piece are separately positioned on the top and bottom between two arc panels 5, upper bullet
The both ends of property piece and lower elastic piece, which are buckled in, to be arranged on two arc panels 5 in corresponding fixing port, is set on the outside of anti-fracture structure
Outer elastomeric plastics 7 are equipped with, fireprotection layer 8 is provided on outer elastomeric plastics 7,8 outside of fireprotection layer is provided with external protection
9, cable core 1 includes intermediate male part by several copper conductors and the insulation inner cladding being wrapped on the outside of several copper conductors, arc panel 5
With the stay hook of upper and lower ends, arc portion in the fixation with fixing port, upper bullet are provided between intermediate male part and stay hook
The hook portion of property piece and lower elastic piece both sides is used cooperatively in stay hook, is filled between outer elastomeric plastics and anti-fracture structure
High polymer elastic layer made of pvc material.
The utility model is simple in structure, reasonable design, can effectively prevent cable core under external force due to stretching and
Impaired or fracture.
