The fixed strip of shape of tail, fixed strip are embedded in dovetail groove.
By using above-mentioned technical proposal, compared with prior art, the utility model is in coaxial cable and digital communication electricity
Flame-retardant layer is equipped with cable, improves fire resistance；And pass through swallow-tailed fixation between data communication cable and coaxial cable
Bar is connected with dovetail groove, in jointing, can move coaxial cable and data communication cable to both sides so that Liang Zhefen
Open, it is convenient to be connected with corresponding joints；And because the material that oversheath uses is respectively provided with certain elasticity, by coaxial cable and numeral
, still can be by the way that fixed strip be again squeezed into coaxial cable and data communication cable in dovetail groove after communication cable separates
Connect once again, it is convenient to reuse.The first fixed station and the second fixed station structure is set to facilitate fixed strip and dovetail groove to set,
Coaxial cable and the original globality of data communication cable are not influenceed.
The utility model is further arranged to：The bottom of the dovetail groove is provided with cross section to be inverted the positioning of isosceles trapezoid
Groove；The long base of the isosceles trapezoid is equal with the bottom width of dovetail groove, and the width on short base is less than the A/F of dovetail groove；
The side of the fixed strip towards dovetail trench bottom is connected with the gib block being adapted to locating slot.
By using above-mentioned technical proposal, when by coaxial cable and data communication cable reconnect, guiding can be passed through
Bar is introduced into the opening of dovetail groove, then fixed strip is squeezed into dovetail groove completely, facilitates coaxial cable and data communication cable again
Connection.
The utility model is further arranged to：The flame-retardant layer is made up of low-smoke halide-free fireproof composite polyolefine material.
By using above-mentioned technical proposal, polyolefin is halogen-free material, is split the carbon dioxide off during burning and water, is not produced
Pernicious gas, use are safer.
The utility model is further arranged to：First fixed station is integrally formed with the first restrictive coating, the second fixed station
It is integrally formed with the second restrictive coating.
By using above-mentioned technical proposal, it is easy to produce and process.
