Abstract
The utility model relates to a polytetrafluoroethylene high altitude air insulation coaxial cable used for aviation, the electronic field, communication, G (generation)/4G antenna of a mobile phone base station, and the like. The cable is formed by tightly combining four layers, namely an inner conductor (1), an insulator (2), an outer conductor (3) and a sheath (4), wherein, the inner conductor (1) is provided with one or more silver-coated copper wires; and the insulator (2) made of polytetrafluoroethylene is a hollow lotus root shaped insulator formed by an inner sleeve (21), an outer sleeve (23), and a connecting rib (22) for connecting the inner sleeve (21) and the outer sleeve (23). By adopting the cable, the diameter of the whole cable is reduced by 15 percent on the premise of same performance, and the weight is reduced by 20 percent at the same time, thereby further facilitating high altitude mounting.
Description
(1) technical field
The utility model relates to the high air-spaced coaxial cable of a kind of polytetrafluoroethylene.Be used for aviation, electronics, communication and cellular base station G or the used antenna of 4G etc.
(2) background technology
At present, the used antenna of cellular base station G or 4G mainly is to use as radio frequency line with the solid-core polyfluortetraethyleinsulating coaxial line, in order to reach antenna gain, cable must have smaller loss, and along with the frequency of utilization of antenna improve constantly with the wire rod course of processing in factor affecting such as heatproof requirement, meeting the requirements of material, to belong to polytetrafluoroethylene the most desirable.But along with the size decreases of development of technology antenna, even the space of a present surface antenna will satisfy the function of four sides antenna in the past, and this just requires the main material radio frequency cable external diameter in the antenna to diminish, but performance is unaffected again simultaneously.And present solid-core polyfluortetraethyleinsulating coaxial line antenna can not satisfy this requirement.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of radio frequency cable external diameter less, but the high air-spaced coaxial cable of the while impregnable again polytetrafluoroethylene of performance.
The purpose of this utility model is achieved in that the high air-spaced coaxial cable of a kind of polytetrafluoroethylene, described cable from the inside to the outside successively by inner wire, insulator, outer conductor and sheath totally four layers closely be composited; Described insulator material is a polytetrafluoroethylene, and this insulator is the hollow lotus root shape insulator of being made up of company's muscle of inner sleeve, outer tube and connection inner sleeve and outer tube.
The beneficial effects of the utility model are:
The high air-spaced coaxial cable of the utility model polytetrafluoroethylene has bigger advantage than like product, lotus root shape insulator is that disposal molding is simpler than similar lapped insulation technology, speed of production is fast, cost is low, air content is higher, and lighter littler than solid-core polyfluortetraethyleinsulating insulating, transmission speed is faster.The high air-spaced coaxial cable of the utility model polytetrafluoroethylene makes the diameter of whole cable little by 15% under the identical prerequisite of performance, simultaneously in light weight 20% this more help the high-altitude and install.
