Description
Technical field
The present invention relates to a kind of cables, and in particular to a kind of compound plow-in cable.
Background technique
The cable burial of direct burial is in ground, since Exterior cable is without armor, therefore the anti-shear performance of cable compared with
Difference, and if cable be cut off, it will cause serious economic impacts, cause to perplex to a large amount of enterprise.Therefore it is directed to direct-burried
The cable of formula, it is required that the anti-shear ability of cable is big.Therefore technical staff is arranged inside cable at present in order to protect circuit
More anti-shearing structure but whether being which kind of structure can only resist shearing, when being sheared, core wire position for the moment
It is motionless, shearing cannot be hidden, once guard member is destroyed, core wire is immediately destroyed, and without secondary protection structure, therefore it is in reality
In use, its anti-shearing effect and bad.
Summary of the invention

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 schematic cross-section of the invention；
Fig. 3 is the structural schematic diagram after guard member shearing of the invention.
Specific embodiment
As depicted in figs. 1 and 2, this compound plow-in cable, including a serving 3, have inside serving 3 one it is hollow
Chamber 1 is arranged at intervals with more than one guard member in hollow cavity 1, and the intermediate of guard member forms a protection chamber 8, more than one
Guard member the circular configuration that forms, adjacent two panels are spliced by one piece or more of arch piece 7 and more than one connector 2
It is connected by a connection piece 2 between arch piece 7,2 middle of connector is strutted outward by the arch piece 7 of two sides and passes through support
The connector 2 opened applies a bounce to the arch piece 7 of two sides, and the arc convex two sides of every piece of arch piece 7 are respectively provided with a core
Line 4, core wire 4, which is all set in, is respectively provided with a buffering positioning region 6 on 2 side of connector, the outer convex surface of arch piece 7, buffers
Positioning region 6 is located between two strands of core wires 4, and contacts with the positioning of 3 inner wall of serving.
In the present embodiment, arch piece 7 is provided with three pieces, the entire guard member of trisection, and entire guard member is determined by buffering
Position portion is set in the hollow cavity of serving in three-point fix mode, and the two sides of arch piece 7 are arc assembly convex surface, even
The two sides of fitting are arc assembly concave surface, and two side positionings of arch piece 7 are incorporated in the arc assembly concave surface of connector simultaneously
Super glue is beaten to be adhesively fixed.When top is sheared, since guard member is bonded as one the structure of formula by glue, at this time
It cannot separate, carry out contact buffering using the buffering positioning region of top arcuate on piece, full wafer arch piece also receives shearing, cuts at this time
Shear force is little, can resist shearing enough, and since core wire is dispersed in two sides, shearing force will not touch the chip of two sides, can
To hide well.
When shearing force constantly increases, arch piece is destroyed with the glue at connector, and top arcuate piece destroys backward
It is intracavitary that lower movement falls to protection, as shown in figure 3, the arch piece of two sides continues convex using two sides when shearing due to protrusion at this time
Rise arch piece as resist shearing force use, when two sides arch piece as shearing resistance cut piece in use, lower pressure can make two
The arch piece of side struts outward, and as shown by the arrows in Figure 3, the core wire positioned at side arch on piece can then be overturn towards lower section, benefit
Use the arc-shaped concave of arch piece as shear protective, and core wire is located at the other side, then can be very good to hide shearing.It is such
Structure possesses more abilities for resisting shearing when being sheared, and while being sheared is to deviate from shearing force, can be fine
Hide shearing, it is more safe.
Wherein, arch piece 7 is all made of elastic metallic plectrum or elastic plastic material is made, and buffering positioning region 6 is tapered
Shape uses resilient blade to be made, and the two sides of buffering positioning region 6 are inserted in the slot in 7 outside of arch piece respectively and beat
Glue is adhesively fixed with arch piece, and connector 2 uses memory metal element, and arc-shaped concave side opens up a notch 15, connector 2
Notch inner wall contacts with each other when in its natural state, and the notch 15 on connector 2 is strutted by 7 elasticity of arch piece of two sides.
Since connector is resilient metal member, deformation can be restored after the support force for losing arch piece, so that the arch piece that top is fallen
The intracavitary rear arch piece by two sides is protected to clamp entering, the arch piece preferably fallen among protection, and two sides clamp
Arch piece afterwards can obtain better anti-shearing force due to concentrating in together, and intensity is higher.
Wherein, the spacing distance between guard member and guard member is 5-8cm.Since centre forms spacing distance, entire electricity
It is by multistage softness section among cable, it may be convenient to bending deformation.
Wherein, the lateral surface of arch piece 7 and 7 integral molding of arch piece, one core wire fixing sleeve 5, on 4 fixing sleeve of core wire
It is provided with a core wire lock chamber, core wire 4 is set in core wire lock chamber and fixes to clamp.
The beneficial effects of the present invention are: the one, present invention is delayed by buffering positioning first when top is sheared
Until arch piece is separated with connector a large amount of shearing force can be absorbed, when the arch piece at top is cut in punching during this process
It cuts after being separated with guard member main body, guard member body interior can be entered, and secondary hide protection；
Two, the present invention is after the arch piece separation at top, during then pushing, can by the arch pieces of two sides into
The secondary contact of row carries out secondary anti-shearing protection using the arch piece of side, and the core wire for being now placed in side arch on piece can be with
Preferably hide shearing far from shearing source towards outer side to overturn.
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.
