Abstract
A kind of flame retardant type coaxially reveals cable, belongs to coaxial leakage field of cable technology.The present invention includes cable main, multiple fire-retardant shearing devices in cable main；Cable main comprises at least inner wire, insulating barrier, outer conductor, flame-retardant layer, protective layer；Fire-retardant shearing device includes the fuse member of housing, the cutting knife in housing, the elastic component located at cutting knife back, connection cutting knife and case inside wall；The blade of cutting knife is towards cable main, and away from cable main certain distance.The present invention can not only protect cable system, while can control the sprawling of the intensity of a fire, to reduce loss.
Description
Technical field
The present invention relates to coaxial leakage field of cable technology, more particularly to a kind of flame retardant type coaxially to reveal cable.
Background technology
Existing flame retardant type cable often simply in cable main increase by one layer of fire proofing made of flame-retardant layer or
Fireprotection layer, although it can prevent or reduce to a certain extent the destruction of cable system, the cladding material still meeting of cable
So that fire spreading, causes unpredicted destruction and loss to its surrounding environment.
The content of the invention
The invention aims to solve the above-mentioned problems of the prior art, there is provided a kind of flame retardant type coaxially reveals electricity
Cable, it can not only protect cable system, while can control the sprawling of the intensity of a fire, to reduce loss.
The purpose of the present invention is achieved through the following technical solutions：
A kind of flame retardant type coaxially reveals cable, including cable main, multiple fire-retardant shearing devices in the cable main；
The cable main comprises at least inner wire, insulating barrier, outer conductor, flame-retardant layer, protective layer；
The fire-retardant shearing device includes housing, the cutting knife in the housing, the elastic component located at the cutting knife back, company
Connect the fuse member of the cutting knife and the case inside wall；The blade of the cutting knife is towards the cable main, and away from the electricity
Cable main body certain distance.
For the present invention by setting fire-retardant shearing device outside cable main, the intensity of a fire when condition of a fire occurring with effective control is climing
Prolong, reduce potential safety hazard as far as possible, reduce loss.During work, when the condition of a fire occurs, during fire spreading to fire-retardant shearing device,
Temperature reaches fuse member by housing, so that fuse member fuses, cutting knife is cut in cable main or straight in the presence of elastic component
Cut-out cable main is connect, effectively to split the cable of its both sides, prevents the intensity of a fire from continuing to spread.Wherein, the blade of cutting knife is away from cable
Main body certain distance so that when fuse member fuses, with enough kinetic energy during the tangential cable main of cutting knife.
As the present invention preferably, the cutting knife includes the blade of multi-disc gap setting, and the every blade is provided with least one
The individual elastic component and fuse member.The process that the structure to cut or cut off is more efficient, is cut off from multiple angles,
Gap relationships cause blade to be independent of each other in incision.
Fusing hole preferably, in the middle part of the blade is provided with as of the invention, the fuse member passes through the fusing hole, and described
The both ends of fuse member connect the case inside wall.The structure more can guarantee that the timely of cut-out, because fuse member is in fusing
The part in hole can be constantly subjected to a power, Gu when the temperature increases, the part will fuse at first.
As the present invention preferably, the blade of the blade is the arc for coordinating the cable main external surface shape.It is described
Structure causes the stress of the various pieces of blade in cut process to be more uniformly distributed, to ensure the fluency of cut process.
As the present invention preferably, the housing includes pressing close to the heat-insulating and sealing seat of the cable main, located at the sealing
Thermal conductive shell on seat.The heat-insulating and sealing seat is made of not transcalent material, with avoid the intensity of a fire or high temperature by every
Heat seal seat is transmitted in cable main, and thermal conductive shell then ensure that fuse member can fuse in time, to ensure its resistance
Fuel efficiency fruit.
As it is of the invention preferably, the seal receptacle its towards one end of the cable main be provided with seal groove, the sealing
Sealing strip is provided with groove.The structure ensure that the sealing of enclosure interior, to ensure the service life of fire-retardant shearing device.
It is an advantage of the invention that：It is simple in construction, it is easy to use, cable system can be effectively protected, while fire can be controlled
The sprawling of gesture, to reduce loss.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the present invention；
Fig. 2 is the internal structure schematic diagram of fire-retardant shearing device in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Embodiment 1, as shown in Figure 1-2, the present invention include cable main 1, multiple fire-retardant in the cable main 1
Shearing device 2；The cable main 1 comprises at least inner wire, insulating barrier, outer conductor, flame-retardant layer, protective layer；It is described fire-retardant to cut
Disconnected device 2 is including described in housing 21, the cutting knife in the housing 21, the elastic component 23 located at the cutting knife back, connection
The fuse member of cutting knife and the madial wall of the housing 21；The blade of the cutting knife is towards the cable main 1, and away from the cable master
The certain distance of body 1.The cutting knife includes the blade 221 of multi-disc gap setting, and the every blade 221 is provided with least one described
Elastic component 23 and fuse member.The middle part of blade 221 is provided with fusing hole 2211, and the fuse member passes through the fusing hole 2211,
And the both ends of the fuse member connect the madial wall of housing 21.The blade of the blade 221 is to coordinate outside the cable main 1
The arc of surface configuration.The housing 21 includes pressing close to the heat-insulating and sealing seat 211 of the cable main 1, located at described heat-insulated close
The thermal conductive shell 212 sealed on seat 211.It towards one end of the cable main 1 is provided with seal groove to the heat-insulating and sealing seat 211,
