Abstract
The utility model relates to an optical-cable filler provided with discrete inner holes, wherein, the discrete inner holes are formed in a solid of the filler. The rigidity of the optical-cable filler is reduced; in the course of twisting the optical-cable filler and other elements together to form a cable core, the filler can deform first when the filler and an optical fiber ferrule are squashed mutually, so that the optical fiber ferrule does not deform, and the transmission performance of an optical-cable cannot be influenced; and the weight of the filler is light, and the material cost is lowered.
Description
Technical field
The utility model relates to filling member, the especially filling member of band discontinuities endoporus in a kind of optical cable.
Background technology
The optical cable filling member is to fill up room in the cable core to make it keep a kind of element of rounding in the stranded process of cable core.Existing filling member is generally the solid filling member that the high density Insulation Material is extruded, its hardness is higher, when the sleeve pipe with other element such as optical fiber is twisted into cable core jointly, easily with sleeve pipe crimp, reduce the useful space of optical fiber in sleeve pipe, thus influence optical cable transmission performance.
Summary of the invention
In order to overcome the deficiency of existing optical cable filling member, the utility model provides a kind of optical cable filling member of band discontinuities endoporus, in that be twisted into altogether in the cable core process not with other element can be with sleeve pipe crimp, thereby can not influence the transmission performance of optical cable.
The optical cable filling member of a kind of band discontinuities endoporus that the utility model provides is provided with the endoporus of discontinuity in the filling member solid.
The beneficial effects of the utility model are: owing to be provided with the endoporus of discontinuity in the filling member solid, reduced the hardness of filling member, be twisted into altogether in the cable core process with other element, when filling member and ferrule mutual extrusion, filling member at first is out of shape, make ferrule indeformable, thereby can not influence the transmission performance of optical cable; The weight saving of filling member, material cost reduces.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model, and Fig. 2 is a longitudinal section of the present utility model synoptic diagram.
In Fig. 1, Fig. 2,1. filling member solid, 2. endoporus.
Embodiment
With reference to Fig. 1, Fig. 2, the air entrance hole is set on the core rod of the mould that extrudes filling member in advance, in the process that extrudes filling member with insulating material of polyethylene, import air by the air entrance hole by phased manner, make the solid 1 interior endoporus 2 that forms discontinuity of filling member, promptly make the utility model.
Claims (1)
1, a kind of optical cable filling member of band discontinuities endoporus is characterized in that being provided with the endoporus of discontinuity in the filling member solid.
