Abstract
The utility model discloses a kind of PTFE composite insulation layer, described PTFE composite insulation layer comprises annular teflon insulation internal layer and annular teflon insulation skin, on described teflon insulation inner layer outer wall, around there being many X-shaped linking arms, described X-shaped linking arm is that annular arm and the cross section coaxial with teflon insulation internal layer is X-shaped; Described X-shaped linking arm is axially uniform along teflon insulation internal layer, and described X-shaped linking arm inner side is connected with teflon insulation inner layer outer wall, and described X-shaped linking arm outside is connected with the outer inwall of teflon insulation.Be set to two-layer and X-shaped linking arm is set between two-layer can makes between two-layer to fill air by insulation system, improving the insulation effect of integral insulation structure; X-shaped linking arm can also improve the overall flexibility of insulation system simultaneously.
Description
Technical field
The utility model relates to a kind of PTFE composite insulation layer.
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, and insulation effect is not good yet simultaneously.It is good that prior art is badly in need of a kind of insulation effect, insulation system rational in infrastructure.
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, PTFE composite insulation layer rational in infrastructure.
For achieving the above object, the technical solution of the utility model has been to provide a kind of PTFE composite insulation layer, described PTFE composite insulation layer comprises annular teflon insulation internal layer and annular teflon insulation skin, on described teflon insulation inner layer outer wall, around there being many X-shaped linking arms, described X-shaped linking arm is that annular arm and the cross section coaxial with teflon insulation internal layer is X-shaped; Described X-shaped linking arm is axially uniform along teflon insulation internal layer, and described X-shaped linking arm inner side is connected with teflon insulation inner layer outer wall, and described X-shaped linking arm outside is connected with the outer inwall of teflon insulation.Be set to two-layer and X-shaped linking arm is set between two-layer can makes between two-layer to fill air by insulation system, improving the insulation effect of integral insulation structure; X-shaped linking arm can also improve the overall flexibility of insulation system simultaneously.
As preferably, described X-shaped linking arm and teflon insulation internal layer and teflon insulation skin are wholely set.Such design makes insulation system Stability Analysis of Structures.
As preferably, described teflon insulation inner layer outer surface is also provided with X-shaped support arm, and described X-shaped support arm is around tetrafluoroethene inner insulating layer outer wall, and described X-shaped support arm is the annular arm coaxial with teflon insulation internal layer; Between the outer inwall of described X-shaped support arm outer rim and teflon insulation, it is support interval; Described X-shaped support arm and teflon insulation internal layer are wholely set.Such structure makes PTFE composite insulation layer also can keep its flexibility in improving insulation effect.
As preferably, described X-shaped linking arm and X-shaped support arm arrange along teflon insulation internal layer axially spaced-apart, and described X-shaped support arm and X-shaped linking arm are polytetrafluoroethylene material.But too many X-shaped linking arm can ensure the intensity of insulation system lack to have sacrificed flexibility, part X-shaped linking arm is replaced with to X-shaped support arm and can take into account flexibility and firmness.
Advantage of the present utility model and beneficial effect are: be set to two-layer and X-shaped linking arm is set between two-layer can makes between two-layer to fill air by insulation system, improving the insulation effect of integral insulation structure; X-shaped linking arm can also improve the overall flexibility of insulation system simultaneously.
Brief description of the drawings
Fig. 1 is the utility model axial section structural representation.
In figure: 1, teflon insulation internal layer; 2, teflon insulation skin; 3, X-shaped linking arm; 4, X-shaped support arm; 5, 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 composite insulation layer, described PTFE composite insulation layer comprises annular teflon insulation internal layer 1 and annular teflon insulation skin 2, on described teflon insulation internal layer 1 outer wall, around there being many X-shaped linking arms 3, described X-shaped linking arm 3 is that annular arm and the cross section coaxial with teflon insulation internal layer 1 is X-shaped; Described X-shaped linking arm 3 is axially uniform along teflon insulation internal layer 1, and described X-shaped linking arm 3 inner sides are connected with teflon insulation internal layer 1 outer wall, and described X-shaped linking arm 3 outsides are connected with outer 2 inwalls of teflon insulation.
Described X-shaped linking arm 3 is wholely set with teflon insulation internal layer 1 and teflon insulation skin 2.
Described teflon insulation internal layer 1 outer surface is also provided with X-shaped support arm 4, and described X-shaped support arm 4 is around tetrafluoroethene inner insulating layer outer wall, and described X-shaped support arm 4 is the annular arm coaxial with teflon insulation internal layer 1; Between outer 2 inwalls of described X-shaped support arm 4 outer rims and teflon insulation, it is support interval 5; Described X-shaped support arm 4 is wholely set with teflon insulation internal layer 1.
Described X-shaped linking arm 3 and X-shaped support arm 4 are along the 1 axially spaced-apart setting of teflon insulation internal layer, and described X-shaped support arm 4 is polytetrafluoroethylene material with X-shaped linking arm 3.
In use, in the time that insulation system bends, X-shaped linking arm 3 plays the connection function between two-layer, and X-shaped support arm 4 plays to support and prevents metamorphosis, and the air between two-layer 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.
