The good cable of a kind of anti-pressure ability of the utility model, compared with prior art with advantages below：
First, by arranging described between the external shielding layer and the armor in the good cable of the anti-pressure ability
Reinforcing rib is substantially improved the anti-pressure ability of cable；Institute is uniformly distributed in by the way that multiple reinforcing ribs are provided in round into array
State between external shielding layer and the armor, the voltage endurance capability for making the armor is integrally lifted, and then enable the resistance to compression of cable
Power is more strengthened；By being to away from the reinforcement by the close strengthening core by the width design of the cross section transverse of the reinforcing rib
It is gradually wide on the direction of core, make the area of the stress surface of the reinforcing rib bigger, so as to play the effect of pressure reduction, the design is assigned
Give the anti-pressure ability that cable is more excellent.Additionally, constituting a centrally disposed strengthening core of circular array in the interior core unit
It is then to improve the bend resistance of cable, tensile resistance.
Second, filler described in the good cable of the anti-pressure ability be polyethylene foams, and the polyethylene steep
Foam plastics are totally-enclosed foam structure.Because air is full of in the abscess, with good cushioning effect；Because poly- second
Alkene foamed plastics has good insulating properties, so may act as insulating barrier；Because polyethylene foams is also prevented with good
Outlet capacity, therefore can effectively prevent the cable core from making moist.Because the polyethylene foams is easy to process, low production cost,
So it has very high cost performance.
3rd, the material of reinforcing rib described in the good cable of the anti-pressure ability is polyurethane rubber.Why this is selected
Plant the material making reinforcing rib and be because that the elasticity of polyurethane rubber is very excellent, and impact resistance is very good, the design
Can promote the reinforcing rib enhancing effect perform to it is ultimate attainment.

Specific embodiment
In order to be better understood from the utility model, with reference to specific embodiments and the drawings traveling one is entered to the utility model
The description of step.
As shown in figure 1, a kind of good cable of anti-pressure ability, including cable core, the cable core is stranded by multiple interior core units
Form.The interior core unit includes inner core 8 and extrudes outside the internal layer sheath 7 in the outside of the inner core 8, the internal layer sheath 7
Side is provided with internal shield 6, and the outside of the internal shield 6 is provided with filler 5, and the outside of the filler 5 is coated with external shield
Layer 4, the outside of the external shielding layer 4 is provided with the equally distributed reinforcing rib 3 of multiple rounded arrays, one end of the reinforcing rib 3
It is fixedly connected with the external shielding layer 4, the other end of the reinforcing rib 3 is then fixedly connected with armor 2, the armor 2
Outside is extruded with outer protective sleeve 1.The quantity of the inner core 8 in the interior core unit is at least one.The plurality of interior core unit is in
Circular array is uniformly distributed, and the centre positioned at the interior core unit composition circular array is provided with a strengthening core, described
Strengthening core outside is in close contact with the interior core unit.In the close strengthening core on the direction away from the strengthening core, institute
Stating the width of the cross section transverse of reinforcing rib 3 gradually increases.
In the utility model, by arranging reinforcing rib 3 between the external shielding layer 4 and the armor 2 cable is made
Anti-pressure ability is substantially improved.The He of the external shielding layer 4 is uniformly distributed in by the way that multiple reinforcing ribs 3 are provided in round into array
Between the armor 2, the voltage endurance capability for making the armor 2 is integrally lifted, and then the anti-pressure ability of cable is more strengthened.It is logical
Cross by the width design of the cross section transverse of the reinforcing rib 3 be by near the strengthening core on the direction away from the strengthening core
It is gradually wide, make the stress surface of the reinforcing rib 3 bigger, so as to play the effect of pressure reduction, it is more excellent that the design gives cable
Anti-pressure ability.Additionally, the centrally disposed strengthening core in the interior core unit composition circular array is then to improve electricity
The bend resistance of cable, tensile resistance.
The filler 5 is polyethylene foams, and the polyethylene foams is totally-enclosed foam structure.Institute
It is because to give the filler 5 good buffer capacity full of air in the abscess with such design.Because polyethylene
Foamed plastics has good insulating properties, so may act as insulating barrier.Because polyethylene foams also has good waterproof
Ability, so can effectively prevent the cable core from making moist.Finally, because the polyethylene foams is easy to process, production cost
It is low, so with very high cost performance.
The material of the reinforcing rib 3 is polyurethane rubber.Why select this material to make the reinforcing rib 3 to be because
The elasticity of polyurethane rubber is very excellent, and impact resistance is very good, and the design can promote the enhancing effect of the reinforcing rib 3
Perform to ultimate attainment.
Because galvanized steel strip has good corrosion resistance, so in order that the utility model has good corrosion resistance
Can, just the armor 2 is designed as to be made up of galvanized steel strip.
In order that the internal layer sheath 7 and the outer protective sleeve 1 have certain anti-flaming function, so the internal layer is protected
Set 7 and the outer protective sleeve 1 are both designed as flame-proof polyethylene sheath.The flame-proof polyethylene sheath is gone back in addition to fire retardancy
There is low cost.
In order that the internal shield 6 have better shield effectiveness, so by the internal shield 6 be designed as by
The aluminum plastic belt wrapping of two-sided aluminium is formed.So design not only increases the shield effectiveness to cable core, also improves anti-external interference
Ability.In order that the screening ability of cable is further lifted, so being then metal wire knitted shielding by the external shielding layer 4
Layer.Make this practicality new by the aluminum plastic belt internal shield 6 of the two-sided aluminium and the synergy of the metal wire knitted screen layer
The screening ability of type is substantially improved.
Embodiment of the present utility model has been described in detail above, but the content is only of the present utility model preferable
Embodiment, it is impossible to be considered as limiting practical range of the present utility model.All impartial changes made according to the utility model scope
