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 inner section schematic diagram of the invention；
Fig. 3 is the end view of fixed part of the invention；
Fig. 4 is the annular installation diagram of each arc protection portion of the invention.
Specific embodiment
As shown in Figure 1 and Figure 4, this compound cable, including more than one fixed part 2, equal shape between adjacent fixed part 2
It at an installation cavity, is connected between adjacent fixed part 2 by more than one arc protection portion 3, between adjacent arc protection portion 3
It is respectively formed a clamping chamber, cable core 1 is embedded in that be set to the intracavitary and elasticity by 3 two sides of arc protection portion of a clamping fixed
The positioning of position portion is fixed；
It is formed between each arc protection portion 3 and protects chamber 4 in one, per share cable core 1 is partially protruded into interior protection chamber 4
It is interior, the outside of arc protection portion 3 is partially stretched out in, the centre of each fixed part 2 is respectively formed a circular through hole 7, circular through hole 7
The position that bottom surface faces cable core opens up an arc-shaped notch 6, as shown in figure 3, cable core 1 passes through circular through hole 7 simultaneously
Part is buckled into arc-shaped notch 6, and an intermediate bar 5 is arranged in the inside of interior protection chamber 4, between intermediate bar 5 and each cable core 1
It is connected by an elastic connection structure.
As shown in figure 4, flexibly positioned portion includes the location sealing piece 33 that insertion is set to arc protection portion two sides, position close
Elasticity is incorporated in the telescopic cavity that 3 two sides of arc protection portion open up mounting 33 respectively, and the bottom surface of telescopic cavity is welded with one
Above the first spring (not shown), the other end of the first spring and the location sealing piece of insertion are welded and fixed, one or more
First spring ejects the location sealing piece of insertion outward, and the two sides of each cable core 1 face the position of location sealing piece 33
A positioning groove is opened up, a positioning convex portion 32 is respectively set in the two sides of arc screening glass, and the positioning of positioning convex portion 32 is incorporated in cable
In the locating slot of core wire 1.
Wherein, as shown in Fig. 2, cable core 1 includes cable serving and cable internal core wire, cable internal core wire is set to
In cable serving, locating slot is opened in the two sides of cable serving.
As shown in Fig. 2, elastic connection structure includes one or more second spring 8, second spring 8 is alongst etc.
Away from being fixed on intermediate bar 5, the other end is connect with the outside wall surface of each cable core 1, and 8 one end of second spring passes through glue and cable
1 outside wall surface of core wire is fixedly connected, and the other end of second spring 8 is fixedly connected by glue with intermediate bar 5, and each second spring is in drawing
Shape is stretched, the pulling force of second spring 8 is less than the positioning assembly force between flexibly positioned portion and cable core 1.
Arc protection portion 3 is all made of elastic metallic sheet material and is made, and using sheet metal, not only saves material, and can also have
Effect resists fire source, in order to increase heat-proof quality, can mount one layer of heat insulation foam layer in the medial surface of arc protection portion, protection enters
The core wire intracavitary to interior protection.
As shown in figure 4, an assembly protrusion 31 is respectively set in the relatively fixed portion two sides of arc protection portion 3, face assembly is convex
Assembly recess portion (not shown) is provided on the fixation end surface in portion 31, arc protection portion 3 is packed by the assembly protrusion of two sides
The simultaneously gluing hydropexis in the assembly recess portion on fixed part both sides of the face.
When cable core clamping is between adjacent two arcs protection portion, all location sealing piece retractions are protected in arc
Inside portion, each first spring is pressurized, and cable core part stretches out in outside at this time, partially protrudes into interior protection chamber, electric at this time
Core is buckled by the positioning convex portion of two sides and is fixed in the locating slot of cable core, and the second spring of inner end cannot at this time
Cable core is pulled in interior protection chamber, a balance is kept.Each cable core normal use and rapid cooling at this time.And
When a fire, cable core serving bear flame calcination, slowly start deformation melt, at this time cable serving with
Positioning assembly force between positioning convex portion is more and more weaker, at this time under the pulling force of second spring, with the fiery cable core quilt contacted
It is intracavitary to pull in interior protection, hides fire source, location sealing piece ejects under the action of the first spring at this time, seals original installation electricity
The space of core, prevents fire source from entering.
And the principle that shearing is hidden in cable core resistance to compression is same as described above, when certain root cable core be pressurized when cable core with
The equilibrant force of second spring is broken, and will be pressed into interior protection chamber at this time and be carried out hiding shear action, realize fire prevention with this
And resistance to compression, solve many deficiencies existing for exposed core wire in the prior art.
The beneficial effects of the present invention are:
One, all core wires are exposed at outside by the present invention, therefore directly heat can radiate, and heat dissipation effect is significantly
It is promoted；
Two, the interior protection of the invention that centre can be retracted into when encountering fire is intracavitary, can effectively and quickly be isolated
Fire source, at the same cable core can be opened after compression elastic connection structure and push into it is interior protection it is intracavitary, then seal again again
The open end for closing interior protection chamber, achievees the purpose that hide shearing.
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.
