Abstract
The utility model discloses a covering strip used in an optical cable. The covering strip comprises a copper foil base material layer. An upper surface and a lower surface of the copper foil base material layer are respectively plated with a first chromium layer and a second chromium layer. The other surfaces of the first chromium layer and the second chromium layer are respectively thermally laminated with plastic composite layers. The plastic composite layer is formed by stacking a polyethylene film and a polypropylene film in sequence. The polyethylene film in the plastic composite layer and the second chromium layer are fixed in a thermally laminate manner. Thickness ratios of the polyethylene films and the polypropylene films in the plastic composite layers are both 1:0.5-2.5. Probability of damaging the plastic layers caused by bending, scratches, and other factors is greatly reduced in the covering strip used in the optical cable. Abrasive resistance, folding resistance, and tear resistance of the composite strip are improved, and a cable diameter is reduced as much as possible, thereby adapting to operating requirements and ensuring structure and quality of the optical cable not to be influenced.
Description
Technical field
The utility model relates to a kind of optical cable composite band, relates in particular to a kind of coating band that is applied to optical cable.
Background technology
Composite band is widely used at modern industry optical cable, extraordinary optical cable and cable communication production field, but how to use actual effect, excellent honest and clean material quite crucial, be enterprise soul, be that enterprise's stable development is competed effective guarantee with properties of product.
Existing be coated on composite steel-plastic belt in optical cable because thickness is larger, cause the cable footpath also larger when being used for making optical cable, to the optical cable that uses at some special occasions, as the ducted optical cable that is laid in, because caliber is less, is difficult to adapt to and lays requirement.
Summary of the invention
The utility model provides a kind of coating band that is applied to optical cable, this coating band that is applied to optical cable greatly reduces due to factors such as bending, scratches, the probability that plastic layer damages occurs, improved the composite band wearing quality, folding resistance and tear resistance, and reduce as far as possible the cable footpath, guarantee that to adapt to request for utilization the structure of optical cable and quality are all unaffected.
For achieving the above object, the technical solution adopted in the utility model is: a kind of coating band that is applied to optical cable, comprise a copper foil base material layer, there are the first chromium layer and the second chromium layer in the upper and lower surface of this copper foil base material layer plating respectively, there is the plastics composite bed on this first chromium layer and the second chromium layer another surface separately thermal-adhering respectively, and this plastics composite bed is stacked gradually by polyethylene film and polypropylene screen and forms.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, the polyethylene film in described plastics composite bed and the second chromium layer thermal-adhering are fixed.
2. in such scheme, the Thickness Ratio in described plastics composite bed between polyethylene film and polypropylene screen is 1:0.5～2.5.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model is applied to the coating band of optical cable, its plastics composite bed stacks gradually composition by polyethylene film and polypropylene screen, greatly reduce due to bending, scratch etc. because of rope, the probability that plastic layer damages occurs, improved the composite band wearing quality, folding resistance and tear resistance have guaranteed the bulk strength of composite band.
2. the utility model is applied to the coating band of optical cable, and its reasonable in design, simple, it has reduced the cable footpath as far as possible, guarantees that to adapt to request for utilization the structure of optical cable and quality are all unaffected.
Description of drawings
In above accompanying drawing: 1, copper foil base material layer; 21, the first chromium layer; 22, the second chromium layer; 3, plastics composite bed; 31, polyethylene film; 32, polypropylene screen.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: a kind of coating band that is applied to optical cable, comprise a copper foil base material layer 1, there are the first chromium layer 21 and the second chromium layer 22 in the upper and lower surface of this copper foil base material layer 1 plating respectively, there is plastics composite bed 3 on this first chromium layer 21 and the second chromium layer 22 another surface separately thermal-adhering respectively, and this plastics composite bed 3 is stacked gradually by polyethylene film 31 and polypropylene screen 32 and forms.
Thickness Ratio in above-mentioned plastics composite bed 3 between polyethylene film 31 and polypropylene screen 32 is 1:0.5～2.5.
Adopt the above-mentioned coating band that is applied to optical cable, its plastics composite bed stacks gradually composition by polyethylene film and polypropylene screen, greatly reduce due to bending, scratch etc. because of rope, the probability that plastic layer damages occurs, improved the composite band wearing quality, folding resistance and tear resistance have guaranteed the bulk strength of composite band; Secondly, the present embodiment is applied to the coating band of optical cable, and reasonable in design, simple, it reduces the cable footpath as far as possible, guarantees that to adapt to request for utilization the structure of optical cable and quality are all unaffected.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow person skilled in the art scholar can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
