The present invention provides a kind of anti-extrusion flexible cable, it includes core, insulating layer, flame-retardant layer, metal circular layer, elastic granule layer, wrapping layer and the outer jacket of from-inner-to-outer setting, the metal circular layer includes becket and the fexible film that is connected between each becket, the elastic granule layer includes the elastic silica gel particle of several monolayer alignments, the elastic granule layer is filled on the fexible film between each becket, and the wrapping layer is arranged tightly around the elastic granule layer.The anti-extrusion flexible cable of the one kind enhances the flexibility of flexible cable by setting elastic granule layer and metal circular layer, while guaranteeing that cable has enough rigidity again.
Description
Technical field
The present invention relates to a kind of flexible cables, specifically, relate to a kind of anti-extrusion flexible cable.
Background technique
Cable is usually made of structures such as the high-strength insulating coatings of metal cable core and covering metal cable core, opposite to cause
It is close, intensity with higher, can tension, bending resistance is also relatively high, but anti-pressure ability is usually poor, by local pressure
When, due to the fine and close construction of cable, strength can be accurately transferred on metal cable core, and metal cable core is caused to be easy to be pressed
It is disconnected.
In order to solve the above problems, people are seeking always a kind of ideal technical solution.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, to provide, a kind of flexibility is preferable, anti-pressure ability is stronger, strong
Spend the anti-extrusion flexible cable of guaranteed one kind.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of anti-extrusion flexible cable, including from
Interior and the core, insulating layer, flame-retardant layer, metal circular layer, elastic granule layer, wrapping layer and the outer jacket that are arranged outside, the becket
Layer includes becket and the fexible film being connected between each becket, and the elastic granule layer includes the bullet of several monolayer alignments
Property silica gel particle, the elastic granule layer are filled on the fexible film between each becket, and the wrapping layer is tightly around the bullet
Property stratum granulosum setting.
Described on base, the gap between the elastic granule layer is filled by the glass powder of low melting point.
Described on base, the elastic granule layer includes several elastic silica gel particles and the silk for stringing each elastic silica gel particle
Line, the length of every elastic silica gel particle strung by silk thread are 3-5m.
Described on base, the elastic silica gel particle spiral that each silk thread is strung is wound around the outside of the metal circular layer.
The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, and specifically, the present invention exists
Increase metal circular layer in cable floor and elastic granule layer, the becket of metal circular layer constitute similar after connecting with fexible film
The structure in joint, enables cable to be easily bent, but in pressure-bearing, metal circular layer can accept pressure first, in addition, by
In the size for needing to consider cable, space constructed by metal circular layer is limited, and after elastic granule layer is added, partial pressure is elastic
Stratum granulosum accepts, diffusion, since elastic granule is filled in grain, pressure transmitting and it is not all be transferred on a bit local cable, and
It is that can spread a certain range to periphery, ensure that the anti-pressure ability of cable.
Detailed description of the invention

Specific embodiment
Below by specific embodiment, technical scheme of the present invention will be described in further detail.
Embodiment 1
As depicted in figs. 1 and 2, a kind of anti-extrusion flexible cable, it is core 1 including from-inner-to-outer setting, insulating layer 2, fire-retardant
Layer 3, metal circular layer 4, elastic granule layer 5, wrapping layer 6 and outer jacket 7, the metal circular layer 4 include becket 4-1 and are connected to
Fexible film 4-2 between each becket 4-1, the elastic granule layer 5 include the elastic silica gel particle of several monolayer alignments, institute
It states on the fexible film 4-2 that elastic granule layer is filled between each becket 4-1, the wrapping layer 6 is tightly around the elastic granule
Layer 5 is arranged.
There are two the effects of metal circular layer 4, and first is resistance to compression, and when cable is pressurized, metal circular layer 4 is first subjected to pressure work
With avoiding cable from being directly pressurized, ring structure itself has stronger non-deformability, improves the non-deformability of cable；
Second is to be readily bent, and cable is frequently necessary to be bent, fexible film 4-2 and becket 4-1 in bending process in metal circular layer 4
Similar joint structure is constituted, does not interfere flexure operation, it is ensured that the bending ability of cable.
The main function of elastic granule layer 5 is complemented each other with metal circular layer 4, the part between becket 4-1, elasticity
Point pressure is diffused to surface pressure by the pressure diffusion that stratum granulosum 5 will be subject to, and local pressure reduces, and promotes anti-pressure ability.
Embodiment 2
The present embodiment the difference from embodiment 1 is that: the gap between the elastic granule layer is filled out by the glass powder of low melting point
It fills, so that structure is more tamped.
Embodiment 3
The present embodiment the difference from embodiment 1 is that: the elastic granule layer includes several elastic silica gel particles and stringing each bullet
Property silica gel particle silk thread, the length of every elastic silica gel particle strung by silk thread is 3-5m, the flexible silicon that each silk thread is strung
Glue particle spiral is wound around the outside of the metal circular layer.
Its main function is easy for forming, and is easily installed, and helical arrangement mode area coverage is more abundant.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
