Step 2: the front end of collar self-insurance sheath is moved between protective layer and braid backward, and make collar driver under stress first end and the second end close to each other;
Step 3: provide a tool, described tool acts on the collar, and under the effect of tool, the external diameter of the above-mentioned formation collar close to each other is less than the internal diameter of braid, is pressed in braid to make the described collar.
Concrete enforcement structure is as follows:
The internal diameter of the described collar is greater than the external diameter of protective layer.
Described first end is provided with some first protuberances and is disposed on the first groove between two adjacent first protuberances, described second end is provided with some second protuberances and is disposed on the second groove between two adjacent second protuberances, described first protuberance and the second groove fit, described second protuberance and the first groove fit.
Compared to prior art; cable-assembly provided by the invention and assembly method thereof; between the braid and protective layer of cable-assembly, increase by a thimble structure; this cover is equipped with the first end and the second end that mutually disconnect; its internal diameter is not fixing; design like this not only decreases the required precision to collar internal diameter size, makes the easier processing and manufacturing of the collar.And relative to prior art; in an initial condition; the collar of the design is semiclosed shape; adopt that the collar of semiclosed shape is easier to be assembled between the braid of cable-assembly and protective layer by the collar; when there will not be assembling, the collar and protective layer interfere and grind away or wrinkle the situation of protective layer.When in the process that the described collar is mounted between protective layer and braid; the described collar by external force drive first end and the second end close to each other; in end-state; by the effect of tool; the external diameter of the above-mentioned formation collar close to each other is less than the internal diameter of braid, is pressed in braid to make the described collar.In addition; by tool, the collar is squeezed to after between braid and protective layer; the described collar can also play an effect supported for the wire rod of inside; when being subject to External Force Acting to make cable-assembly, external force is delivered on outer quilt, braid and the collar, and then the inner wire rod of protective wire cable assembly can not be impaired.
[embodiment]
As shown in Figures 1 to 6; the invention discloses a kind of cable-assembly 100, it comprise be positioned at one wire rod 1 for signal transmission extended along longitudinally at its center, the protective layer 2 be coated on outside wire rod 1, be coated on the braid 3 outside protective layer 2 and be coated on outside braid 3 outer by 4.Described protective layer 2 is aluminium foil or tinfoil paper material.Described cable-assembly 100 also comprises the collar 5 be arranged between braid 3 and protective layer 2.Described braid 3 comprise be located at outer by the horizontal part 31 in 4 and the diffusion part 32 that turns up from horizontal part 31.
Described wire rod 1 comprises some heart yearns (not shown), be coated on inner insulating layer 11 outside heart yearn.The two ends of wire rod 1 are the link 12 that can be connected to electric connector (not shown).
The described collar 5 is made for metal material, and it comprises the first end 51 and the second end 52 that mutually disconnect.In an initial condition; this collar 5 is in semiclosed shape; be mounted in the process between protective layer 2 and braid at the described collar 5; the first end 51 of the described collar 5 and the second end 52 close to each other; in which final state, by the effect of extraneous tool, the external diameter of the above-mentioned formation collar 5 close to each other is less than the internal diameter of braid 3; to make the described collar 5 be pressed in braid 3, now the described collar 5 is between the horizontal part 31 and protective layer 2 of braid 3.In the present embodiment, the first V-shaped groove 512 that described first end 51 is provided with some the first V-shaped protuberances 511 and is disposed between two adjacent first protuberances 511, the second V-shaped groove 522 that described second end 52 is provided with some the second V-shaped protuberances 521 and is disposed between two adjacent second protuberances 521, described first protuberance 511 and the second protuberance 521 mutually stagger and arrange, and described first groove 512 and the second groove 522 mutually stagger and arrange.Described first protuberance 511 coordinates with the second groove 522, and the second protuberance 521 coordinates with the first groove 512.Described first protuberance 511, second protuberance 521 is equipped with a junction 513,523, and described first groove 512, second groove 522 is equipped with a mating surface 514,524, and described connecting portion 513,523 can be connected with corresponding mating surface 514,524.In other embodiments, the first end 51 of the described collar 5 and the second end 52 can also be arranged to other shapes, as as described in first end 51 can be set to the protuberance of semicircle shape, described second end 52 can be set to the depressed part of a semicircle shape in order to connect with the protuberance of aforementioned semicircle shape.In the present embodiment, when the collar 5 is pressed in braid 3, when being between the horizontal part of braid 3 and protective layer 2, the described collar 5 is both ends open, and the internal diameter of the described collar 5 is greater than the external diameter of protective layer 2.Design like this; make the collar 5 can also play an effect supported for the wire rod 1 of inside; when being subject to External Force Acting to make cable-assembly 100, external force is delivered to outer by 4, on braid 3 and the collar 5, and then the inside wire rod 1 of protective wire cable assembly can not be impaired.
Invention further discloses the assembly method of cable-assembly 100, this assembly method comprises the steps:
