Description
Technical field
The utility model relates to a kind of PTFE double hyer insulation cover.
Background technology
As everyone knows, between the setting of existing radio frequency cable insulation system and inner wire and outer conductor for insulation between the two.But existing insulation system is generally solid insulation system, for reinforced insulation effect need to constantly strengthen the thickness of insulation system.Such structure is wasted material not to the utmost, increases cost of manufacture, and the soft heart of insulation effect and body is all unsatisfactory simultaneously.It is good that prior art is badly in need of a kind of insulation effect, flexible, the good insulating case of intensity.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of insulation effect good, flexible, the good PTFE double hyer insulation of intensity cover.
For achieving the above object, the technical solution of the utility model has been to provide a kind of PTFE double hyer insulation cover, described PTFE double hyer insulation cover comprises annular teflon insulation inner sleeve and annular teflon insulation overcoat, described teflon insulation outer wall of inside race is provided with connecting hose, and described connecting hose spiral is around teflon insulation outer wall of inside race; Described connecting hose inner side is connected with teflon insulation inner sleeve, and described connecting hose outside is connected with teflon insulation overcoat;
In described PTFE double hyer insulation cover, be provided with support flexible pipe, described support flexible pipe comprises inner support flexible pipe and coordinates the outer support flexible pipe supporting with inner support flexible pipe;
Described teflon insulation outer wall of inside race is provided with inner support flexible pipe, described inner support flexible pipe vertically spiral around teflon insulation outer wall of inside race; Described teflon insulation outer casing inner wall is provided with outer support flexible pipe, described outer support flexible pipe vertically spiral surrounding in teflon insulation outer casing inner wall;
Between described inner support flexible pipe outer rim and outer support flexible pipe inner edge, be provided with support interval.
Be set to two-layer and connecting hose is set between two-layer can makes between two-layer to fill air by insulation system, improve the insulation effect of integral insulation structure, but too many connecting hose can ensure the intensity of insulation system lack to have sacrificed flexibility, part connecting hose is replaced with to support flexible pipe and can take into account flexibility and firmness.Stay pipe is set to inside and outside body and can prevents body excessive deformation in the time of bending simultaneously.
As preferably, described connecting hose and teflon insulation inner sleeve and teflon insulation overcoat are wholely set; Described inner support flexible pipe and teflon insulation inner sleeve are wholely set; Described outer support flexible pipe and teflon insulation overcoat are wholely set.Such design makes insulation system Stability Analysis of Structures.
As preferably, described connecting hose and support the cavity interval of hose loop between teflon insulation inner sleeve and teflon insulation overcoat and arrange; Described support flexible pipe pipe thickness is greater than connecting hose pipe thickness.Such design is the further optimization to scheme.
Advantage of the present utility model and beneficial effect are: be set to two-layer and connecting hose is set between two-layer can makes between two-layer to fill air by insulation system, improve the insulation effect of integral insulation structure, but too many connecting hose can ensure the intensity of insulation system lack to have sacrificed flexibility, part connecting hose is replaced with to support flexible pipe and can take into account flexibility and firmness.Support flexible pipe is set to inside and outside body and can prevents body excessive deformation in the time of bending simultaneously.
Brief description of the drawings
Fig. 1 is the utility model axial section structural representation.
In figure: 1, teflon insulation inner sleeve; 2, teflon insulation overcoat; 3, connecting hose; 4, inner support flexible pipe; 5, outer support flexible pipe; 6, support interval.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, a kind of PTFE double hyer insulation cover, described PTFE double hyer insulation cover comprises annular teflon insulation inner sleeve 1 and annular teflon insulation overcoat 2, described teflon insulation inner sleeve 1 outer wall is provided with connecting hose 3, and described connecting hose 3 spirals are around teflon insulation inner sleeve 1 outer wall; Described connecting hose 3 inner sides are connected with teflon insulation inner sleeve 1, and described connecting hose 3 outsides are connected with teflon insulation overcoat 2;
In described PTFE double hyer insulation cover, be provided with support flexible pipe, described support flexible pipe comprises inner support flexible pipe 4 and coordinates the outer support flexible pipe 5 supporting with inner support flexible pipe 4;
Described teflon insulation inner sleeve 1 outer wall is provided with inner support flexible pipe 4, described inner support flexible pipe 4 vertically spiral around teflon insulation inner sleeve 1 outer wall; Described teflon insulation overcoat 2 inwalls are provided with outer support flexible pipe 5, described outer support flexible pipe 5 vertically spiral surrounding in teflon insulation overcoat 2 inwalls;
Between described inner support flexible pipe 4 outer rims and outer support flexible pipe 5 inner edges, be provided with support interval 6.
Described connecting hose 3 is wholely set with teflon insulation inner sleeve 1 and teflon insulation overcoat 2; Described inner support flexible pipe 4 is wholely set with teflon insulation inner sleeve 1; Described outer support flexible pipe 5 is wholely set with teflon insulation overcoat 2.
Described connecting hose 3 and the cavity interval of support hose loop between teflon insulation inner sleeve 1 and teflon insulation overcoat 2 arrange; Described support flexible pipe pipe thickness is greater than connecting hose 3 pipe thicknesses.
In use, in the time that insulation system bends, connecting hose 3 plays the connection function between two-layer, inner support flexible pipe 4 coordinates with outer support flexible pipe 5 to support and plays and prevent metamorphosis, connecting hose 3 is all used polytetrafluoroethylene material with supporting flexible pipe, and the air between ectonexine and two-layer polytetrafluoroethylene material play good insulating effect.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
