Frame includes the frame body for surrounding sheath and the array cushioning supportive part along frame body radial direction.
Further, buffer cell described in every group includes 3-5 Buffer Unit being arranged in sheath outer circle circumferential direction.
Further, the Buffer Unit includes the elastic ball being mounted on retainer and delays to the arc of elastic ball setting
Punching.
Further, the cable core includes several conductor assemblies, and each conductor assembly includes two mutually twisted conductors,
This two conductor passes through respectively arranged insulator separation on the outside of the two.
Further, the conductor uses pure cu conductor or silver-plated copper conductor.
Further, the cushioning supportive part uses rod piece flexible, and one end is connect with the frame body, and the other end is successively worn
Inner cushion layer outer surface is fixed on after crossing sheath, internal shield.
Further, the armor uses steel-tape armouring layer.
Further, the internal shield uses plastic-aluminum combined belt or copper strip layer.
Compared with the existing technology, the invention has the advantage that
In the invention, cushioning supportive part and Buffer Unit cooperate, and can play splendid pressure resistance and shock resistance,
Cable core and internal shield inside effective protection have ensured the stability of cable work, extend cable service life.

It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description the invention and simplifies description, rather than indicate
Or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot understand
For the limitation to the invention.In addition, term " first ", " second " etc. are used for description purposes only, and should not be understood as indicating
Or it implies relative importance or implicitly indicates the quantity of indicated technical characteristic." first ", " second " etc. are defined as a result,
Feature can explicitly or implicitly include one or more of the features.In the description of the invention, unless separately
It is described, the meaning of " plurality " is two or more.
In the description of the invention, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition
State concrete meaning of the term in the invention.
Below with reference to embodiment come the present invention will be described in detail create.
A kind of cable of pressure-resistant anti-shock, as depicted in figs. 1 and 2, be orderly arranged outside each including cable core 1 and cable core in
Bed course 2, internal shield 3, sheath 4, outer bed course 5, armor 6 and outer jacket 7；It is equipped between the sheath and outer bed course
Buffer protection structure 8；The buffer protection structure includes being uniformly arranged on the retainer 9 and retainer for surround sheath setting
Array buffer cell；The retainer includes the frame body 10 for surrounding sheath and the array cushioning supportive part along frame body radial direction
11.In order to ensure the normal use under small space, tear rope can be set between armor and outer jacket, if necessary
(when laying cable such as in the poling of small diameter tube), can use tear rope, outer jacket is removed, to reduce the shape of this cable
Size.
It all includes the 3-5 cushioning supportive parts uniformly distributed along frame body circumferencial direction that each group (cushioning supportive part) general, also
Be one group include 3-5 monomer cushioning supportive part, effectively ensured the stress equalization of cable core all directions, can especially have
Effect resists the impact of all directions.
Wherein, buffer cell described in every group includes 3-5 Buffer Unit being arranged in sheath outer circle circumferential direction.On
Stating Buffer Unit includes the elastic ball 12 being mounted on retainer and the arc buffering piece 13 to elastic ball setting.By external force
When impact (or extruding), outer jacket forms first of measuring body barrier, effectively carries, meanwhile, make jointly with buffer protection structure
With, to sheath and its within structure formed effective protection.In addition, outer jacket, buffer protection structure and sheath and interior
Bed course plays the role of buffering and protection jointly, splendid to the protecting effect of cable core, has permanent protective property.
The arrangement in general, cushioning supportive part and elastic ball are staggered, that is, cushioning supportive part do not correspond to elastic ball, can be every
One cushioning supportive part is set between two elastic balls, and the impact force being effectively ensured in cable core circumferencial direction shares buffering as far as possible
On component or cushioning supportive part, rather than a certain part is loaded, weakens influence of the impact force to this cable.
Above-mentioned cable core includes several conductor assemblies, and each conductor assembly includes two mutually twisted conductors 14, this two
Conductor passes through respectively arranged insulator separation on the outside of the two.Above-mentioned conductor uses pure cu conductor or silver-plated copper conductor.Guarantee to pass
The high-purity of defeated medium, high conductivity.Above-mentioned internal shield uses plastic-aluminum combined belt or copper strip layer, and there is good shielding to make
With.Above-mentioned armor uses steel-tape armouring layer.
Above-mentioned cushioning supportive part uses rod piece flexible, and one end is connect with the frame body, and the other end sequentially passes through interior shield
Inner cushion layer outer surface is fixed on after layer, internal shield.Cushioning supportive part and Buffer Unit cooperate, can play splendid pressure resistance and
Shock resistance, cable core and internal shield inside effective protection have ensured the stability of cable work, extend cable and use
Service life.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
