Abstract
The utility model discloses a kind of double-layer insulating structure, described double-layer insulating structure comprises annular teflon insulation internal layer and annular teflon insulation skin, on described teflon insulation inner layer outer wall, around there being many tube connectors, described tube connector is the ring seal pipe coaxial with teflon insulation internal layer; Described tube connector is axially uniform along teflon insulation internal layer, and described tube connector inner side is connected with teflon insulation inner layer outer wall, and described tube connector outside is connected with the outer inwall of teflon insulation.Be set to two-layer and tube connector is set between two-layer can makes between two-layer to fill air by insulation system, improving the insulation effect of integral insulation structure; Tube connector can also improve the overall flexibility of insulation system simultaneously.
Description
Technical field
The utility model relates to a kind of double-layer insulating structure.
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, and the double-layer insulating structure that a kind of insulation effect is good, rational in infrastructure is provided.
For achieving the above object, the technical solution of the utility model has been to provide a kind of double-layer insulating structure, described double-layer insulating structure comprises annular teflon insulation internal layer and annular teflon insulation skin, on described teflon insulation inner layer outer wall, around there being many tube connectors, described tube connector is the ring seal pipe coaxial with teflon insulation internal layer; Described tube connector is axially uniform along teflon insulation internal layer, and described tube connector inner side is connected with teflon insulation inner layer outer wall, and described tube connector outside is connected with the outer inwall of teflon insulation.Be set to two-layer and tube connector is set between two-layer can makes between two-layer to fill air by insulation system, improving the insulation effect of integral insulation structure; Tube connector can also improve the overall flexibility of insulation system simultaneously.
As preferably, described tube connector 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 stay pipe, and described stay pipe is around tetrafluoroethene inner insulating layer outer wall, and described stay pipe is the ring seal pipe coaxial with teflon insulation internal layer; Between the outer inwall of described stay pipe outer rim and teflon insulation, it is support interval; Described stay pipe and teflon insulation internal layer are wholely set.Such structure makes double-layer insulating structure also can keep its flexibility in improving insulation effect.
As preferably, described tube connector and stay pipe arrange along teflon insulation internal layer axially spaced-apart, and described stay pipe wall thickness is greater than tube connector wall thickness.But too many tube connector can ensure the intensity of insulation system lack to have sacrificed flexibility, part tube connector is replaced with to stay pipe and can take into account flexibility and firmness.
Advantage of the present utility model and beneficial effect are: be set to two-layer and tube connector is set between two-layer can makes between two-layer to fill air by insulation system, improving the insulation effect of integral insulation structure; Tube connector 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, tube connector; 4, stay pipe; 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 double-layer insulating structure, described double-layer insulating structure 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 tube connectors 3, described tube connector 3 is the ring seal pipe coaxial with teflon insulation internal layer 1; Described tube connector 3 is axially uniform along teflon insulation internal layer 1, and described tube connector 3 inner sides are connected with teflon insulation internal layer 1 outer wall, and described tube connector 3 outsides are connected with outer 2 inwalls of teflon insulation.
Described tube connector 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 stay pipe 4, and described stay pipe 4 is around tetrafluoroethene inner insulating layer outer wall, and described stay pipe 4 is the ring seal pipe coaxial with teflon insulation internal layer 1; Between outer 2 inwalls of described stay pipe 4 outer rims and teflon insulation, it is support interval 5; Described stay pipe 4 is wholely set with teflon insulation internal layer 1.
Described tube connector 3 and stay pipe 4 are along the 1 axially spaced-apart setting of teflon insulation internal layer, and described stay pipe 4 wall thickness are greater than tube connector 3 wall thickness.
In use, in the time that insulation system bends, tube connector 3 plays the connection function between two-layer, and stay pipe 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.
