Specific embodiment
As shown in Figure 1, this fire prevention Compression-resistincable cable, including cable external protection 7, the inside of cable external protection 7 have one
A cable installation cavity 12, cable core 11 are set in cable installation cavity 12, and the external opposite face of cable core 11 is respectively set
One arc protrusion 1, arc protrusion 1 extend along the length direction of cable core 11；
The two sides of arc protrusion 1 have been placed equidistant with more than one rotation slot (not shown), rotation slot inner wall two sides difference
One shaft hole is set, a telescopic rod is packed into each rotation slot, a shaft 8, shaft 8 is respectively set in the two sides of the bottom of telescopic rod
On be set with a torque spring (not shown), shaft 8 is elastically mounted in shaft hole by torque spring, be located at cable core it is same
Two telescopic rods up and down of side in its natural state when contact with each other；
The two sides of cable core 11 are respectively arranged with an inner protective layer 3, and the two sides of inner protective layer 3 are bonded in flexible respectively
On the contact nose bar 5 of bar output end, the medial surface two sides of cable external protection 7 are respectively arranged with retention bead 9 in one, two sides
Interior retention bead 9 is respectively formed a limit installation area, the telescopic rod of upper and lower side and interior guarantor in the top and bottom of cable installation cavity
Sheath 3 is respectively protruding into limiting two sides in the limit installation area.
As shown in Fig. 2, the interior arc-shaped shape of retention bead, hollow plastics are made, the inside of interior retention bead 9 is respectively formed
One arc filled cavity 92, arc filled cavity 92 is interior to fill inert gas, and the lateral surface of interior retention bead is inserted with one
Heat conducting bar 91 more than root, 91 one end of heat conducting bar through being inserted in interior retention bead 9 and gluing hydropexis, heat conducting bar 91 it is another
One end is inserted in gluing hydropexis in cable external protection 7, and heat conducting bar 91 is elastic metallic bar, protects outside outboard end and cable
The lateral surface of layer is concordant, one of heat conducting bar 91 effect be when there is flame in outside, the heat transfer of flame to heat conducting bar so that
The interior retention bead contacted with heat conducting bar can soften, so that telescopic rod is no longer influenced by the limit of interior retention bead, it is thermally conductive
Bar when not in use, is then the thermally conductive use for cable internal core, can increase the thermally conductive of cable core in this case
Performance will not be limited by the structure of fireprotection layer and resistance to compression layer and reduce heat-sinking capability.
As shown in Figure 1, the middle position of arc protrusion, which is molded, forms an outer retention bead 4, after inner protective layer 3 is stretched
It is contacted at its bottom center with the outer retention bead 4 of protrusion, forms a triangular structure, after inner protective layer restores deformation,
It is respectively formed a triangle protection structure in the top and bottom of cable core, not only has good compression strength, and can shape
At an external protective structures, further the intermediate cable core of protection, prevents the erosion of flame.
In the present embodiment, telescopic rod includes a fixed axostyle 6 and a telescopic rod 2, is respectively provided with one in fixed axostyle and stretches
Contracting axis hole, the axis hole that stretches is interior to be packed into a spring (not shown), and the other end of spring is contacted with the telescopic rod bottom of insertion, telescopic rod
By the outside side ejection of spring, spring will contact nose bar and 7 inner wall face contact of cable external protection compresses.It is flexible by being arranged
Bar so that contact nose bar always with the inside face contact of cable external protection compress so that contact nose bar one end always with protrusion
Interior retention bead contact limit, prevent telescopic rod from restoring deformation under the action of torque spring.
And the principle is utilized, after interior retention bead is destroyed because of flame, telescopic rod is under the action of torque spring
Restore deformation, as shown in figure 4, inner protective layer is softened at this time, is formed in together and protect structure, preferably protect inside cable core
Line.
Wherein, as shown in figure 3, inner protective layer 3 is in such a way that elastic rubber layer 32 is combined with aluminium-foil paper 31, elastic rubber
Layer 32 is located at the bottom of aluminium-foil paper, external flame is born by aluminium-foil paper 31, and F R Oil is smeared in the outside of elastic rubber layer
Paint layer.Due to materials of aluminum foil paper, there is unusual fireproofing and heat resistant performance, prevent flame rapid damage inner protective layer, increase fire resisting
Ability.
And when cable integral head is pressurized, by utilizing telescopic rod bottom as buffering in the ringent structure of loudspeaker
Elastic deformation occurs for torque spring, therefore telescopic rod is whole preferably with elastic metallic in the present embodiment, makes it have preferably tough
Property, it can be good at absorption pressure, and then reach better buffering, increase the compression strength of cable entirety, preferably protection electricity
Core.
The beneficial effects of the present invention are: the present invention uses the structure of simple cable external protection, it can when usually using
Good heat dissipation performance is obtained, and when being pressurized, it can have better resistance to compression buffer capacity, while can have flame in outside
When, external in cable core form an inner protective layer, further increases fire protecting performance by inner protective layer.
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.
