Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the sectional view of cable of the invention；
Fig. 3 is the partial enlarged view of expander of the invention；
Fig. 4 is the sectional view of connector of the invention.
Specific embodiment
As depicted in figs. 1 and 2, this fire prevention composite cable, by one section or more of serving 2 and more than one connector
Splicing forms, and is respectively provided with a connection piece between adjacent serving 2, and fixation contacts between serving 2 and connector end face；
More than one cavity 21 is offered around the circle of serving one on serving 2, as shown in figure 3, filling out in cavity 21
An expander 7 is filled, fills inert gas in expander 7, the bottom of expander 7 is respectively provided with a backplane level 77,77 bottom of backplane level
It is provided with more than one compressed spring 74, the bottom of compressed spring 74 is fixedly connected with 21 bottom surface of cavity, the outside of expander 7
End is respectively provided with a thermally conductive sheet 1, and 1 two sides of thermally conductive sheet are contacted with 21 lateral surface compressing of cavity respectively, and thermally conductive sheet 1 is by expander, backplane level
And compressed spring limits in cavity, cable core built in one section or more of serving, while thermally conductive sheet can also be used as gold
Belong to ornamental strip and has better fire line.
Wherein, as shown in figure 3, expander 7 includes a rubber swelling layer 71 with swelliong power, have inside expanding layer 71
Have a filled cavity 75, the same side of expanding layer 71 its close to the position of thermally conductive sheet be respectively provided with a jet port 72, entire filled cavity
Filling extinguishing chemical and part inert gas in 75, jet port 72 are sealed by the sealing 73 of cavity interior walls.
In the present embodiment, sealing 73 uses a silica gel piece, and silica gel piece insertion is set in cavity 21, fills out in filled cavity 75
Fill fire foam and carbon-dioxide fire engine gas.Entire expander expands after being filled with extinguishing chemical and inert gas, body
Product becomes larger and then fills full entire cavity, is then clamped and is sealed by thermally conductive sheet in the lateral surface of cavity, expander is pressurized, bottom
Compressed spring be pressurized and generate bounce, but since thermally conductive sheet has certain restraining ability, therefore when commonly used, pass through
The power of expander and spring can not open thermally conductive sheet, therefore need to control the expanded size of expander.
Wherein, thermally conductive sheet 1 is metal heat-conducting thin slice, and medial surface is provided with one layer of silica gel heat-conducting layer, thermally conductive by silica gel
Layer is pasted onto the lateral surface of expander, and thermally conductive sheet 1 is arc shape, and radian is identical as the external radian of serving, with outer quilt
Layer 2 is spliced into a completely circular structure, and when there is fire source in outside, thermally conductive sheet heating under fire source effect of respective side, heat passes through
Silica gel heat-conducting layer passes to expander, and due to containing gas inside expander, which is inert gas, whole after gas is heated
A expander can reexpand certain size, can be misplaced originally with silica gel piece by the jet port that silica gel piece seals at this time, most
Under the excessive extruding force of bottom expansion body, thermally conductive sheet is no longer able to limit expander and opened whole thermally conductive sheet, sprays at this time
Inert gas and fire foam are quickly sprayed in loophole, and then is quickly contacted with the fire source on periphery, achieve the purpose that fire extinguishing.
But since jet port is all only provided with the single side face of the same side, and serving two sides are contacted with connector rotation, therefore in unilateral side
Under the action of impact force, the rotation that entire serving can be pico-, and after the intracorporal extinguishing chemical of the expansion of bottommost sprays,
The quality of the side is most light, other expansion weight weights, cooperates gravity and unilateral impact force, so that the company of serving opposite sides
Fitting rotation, the expander not being heated at this time are further continued for bearing heat, this process can not only disperse the heated position of cable,
So that heat source is born in each face of cable serving, and can be with cracking fully open expander, so that expansion is intracorporal
Extinguishing chemical and gas spray, and guarantee fire-fighting dose to the greatest extent.
Wherein, backplane level 77 is a hard plastic sheet, 74 one end of compressed spring and 77 bottom gluing hydropexis of backplane level, separately
One end and 21 bottom surface gluing hydropexis of cavity, the two sides of thermally conductive sheet 1 are each provided with more than one dimpling portion 76, face dimpling portion
76 cavity interior walls are provided with recess, and dimpling portion 76 is buckled into limiting thermally conductive sheet, the assembly of dimpling portion 76 and recess in recess
Power must be enough, and otherwise expander will be opened when non-heat expands.
Wherein, the fixed bracket 8 of external setting one of cable core 5, fixed bracket 8 are fixedly installed in serving and outer quilt
Layer injection molding is integrated.
As shown in figure 4, connector includes a middleware 3 and the rotating member 4 for being set to 3 two sides of middleware, 3 liang of middleware
Side is respectively arranged an annular groove, and the rotating member end face of face annular groove is provided with corresponding bulge loop 42, bulge loop 42 partially protrude into
In annular groove, the inserting end lateral surface of bulge loop 42 is provided with one or more ball 41, and 41 bottom of ball rolls and is set to bulge loop
In first ball grooves of 42 lateral surfaces, the outboard end rolling of ball 41 is set in the second ball grooves being arranged on annular groove face,
Rotating member lateral surface is adhesively fixed with serving end face gluing water.When the impact of serving unilateral side, serving band turn can be made
Moving part rotates with respect to middleware, realizes change of the different expanders in orientation with this.
The beneficial effects of the present invention are: the present invention can be by the way of expanded by heating, so that ejecting when there is fire source
Inert gas and partial extinguishing chemical quickly extinguish flare and periphery flame on serving, while can be realized unilateral side
It sprays to realize that slow rotation, help are rapidly separated fire source and preferably fire extinguishing.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
