Abstract
The utility model discloses a kind of composite insulation layer, described composite insulation layer comprises annular teflon insulation internal layer and annular teflon insulation skin, and described teflon insulation internal layer is connected by X-shaped linking arm with annular teflon insulation skin; Described X-shaped linking arm is that strip linking arm and cross section are X-shaped, and described X-shaped linking arm is uniform and extension vertically around teflon insulation inner layer outer wall; Described X-shaped linking arm inner side is connected with teflon insulation inner layer outer wall, and institute's 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, also can increase the integral, flexible of insulated tube simultaneously.
Description
Technical field
The utility model relates to a kind of 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, increases cost of manufacture, 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 composite insulation layer 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 composite insulation layer, described composite insulation layer comprises annular teflon insulation internal layer and annular teflon insulation skin, and described teflon insulation internal layer is connected by X-shaped linking arm with annular teflon insulation skin; Described X-shaped linking arm is that strip linking arm and cross section are X-shaped, and described X-shaped linking arm is uniform and extension vertically around teflon insulation inner layer outer wall; Described X-shaped linking arm inner side is connected with teflon insulation inner layer outer wall, and institute's 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, also can increase the integral, flexible of insulated tube simultaneously.
As preferably, described X-shaped linking arm and teflon insulation internal layer and teflon insulation skin are one-body molded.Such design makes insulation system stable.
As preferably, described teflon insulation inner layer outer wall is provided with X-shaped support arm, and described X-shaped support arm is uniform and extend vertically described X-shaped support arm and the setting of X-shaped linking arm interval around teflon insulation inner layer outer wall; Between the outer inwall of described X-shaped support arm outer rim and teflon insulation, be provided with support interval.Such structure makes double-layer insulating structure also can keep its flexibility in improving insulation effect.
As preferably, described X-shaped linking arm and X-shaped support arm are polytetrafluoroethylene material.Such design is the further optimization to scheme.
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, improve the insulation effect of integral insulation structure, also can increase the integral, flexible of insulated tube simultaneously.
Brief description of the drawings
Fig. 1 is radially sectional structure schematic diagram of the utility model.
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 composite insulation layer, described composite insulation layer comprises annular teflon insulation internal layer 1 and annular teflon insulation skin 2, and described teflon insulation internal layer 1 is connected by X-shaped linking arm 3 with annular teflon insulation skin 2; Described X-shaped linking arm 3 is for strip linking arm and cross section are X-shaped, and described X-shaped linking arm 3 is uniform and extension vertically around teflon insulation internal layer 1 outer wall; Described X-shaped linking arm 3 inner sides are connected with teflon insulation internal layer 1 outer wall, and institute's X-shaped linking arm 3 outsides are connected with outer 2 inwalls of teflon insulation.
Described X-shaped linking arm 3 is one-body molded with teflon insulation internal layer 1 and teflon insulation skin 2.
Described teflon insulation internal layer 1 outer wall is provided with X-shaped support arm 4, and described X-shaped support arm 4 is uniform and extension vertically around teflon insulation internal layer 1 outer wall, and described X-shaped support arm 4 arranges with X-shaped linking arm 3 intervals; Between outer 2 inwalls of described X-shaped support arm 4 outer rims and teflon insulation, be provided with support interval 5.
Described X-shaped linking arm 3 and X-shaped support arm 4 are polytetrafluoroethylene material.
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.
Claims (4)
