Abstract
The connector includes the outer conductor, the inner conductor assembled in the hole of the outer conductor and the isolation medium between the inner conductor and the outer conductor. The connection between the non-coaxial type spring jack and the circular pin constitutes the inner conuctor. In the segment, where the impedance presents the distribution of alternated betwen capacitance and inductance, the isolation medium between inner and outer conductor is the composite isolation media composed of the solid and gas isolation media. In the segment, where the impedance presents the distribution of resistance, the isolation medium between inner and outer conductor is the solid isolation media. Teflon or high-pressure polyethylene or composite material composed of Teflon and plastic are selected as the solid isolation.

Two, background technology
At present, F type, the FL10 type radio frequency connector of cable television system equipment uses such as splitter, distributor, trunk amplifier mainly are made up of outer conductor, inner wire and the dielectric between internal and external conductor.In order to cooperate with the contact pin of φ 0.8～φ 1.6, inner wire is formed by connecting by non-coaxial type spring jack and circular rod member, but dielectric is solid matter, thereby causes echo to increase, transmission performance reduces, and with the reflection loss after the last 75 Europe loads is-16dB.For reducing reflection loss, the prior art scheme generally is to compensate by internal circuit, and the workload of can increase design like this, making and debug makes troubles and difficulty to manufacturer.
Three, summary of the invention
The present invention is directed to the deficiency that prior art exists, a kind of improved radio frequency connector is provided, this kind radio frequency connector can not only improve transmission performance effectively, reduces reflection loss, and simple in structure, is convenient to make.
Technical scheme of the present invention is: the form of expression according to the radio frequency connector impedance is divided into 1 district and 2 districts with it, impedance is electric capacity, the inductance section of being alternately distributed is 1 district (proparea), it is 2 districts (back zones) that impedance is the distribution of resistance section, by the structure that changes dielectric 1 district and 2 districts are compensated respectively, realize the coupling transmission.In 1 district, the dielectric between internal and external conductor is the compound inslation medium that solid dielectric insulation and gas-insulated medium are formed; In 2 districts, the dielectric between internal and external conductor is a solid dielectric insulation; The size of dielectric and outer conductor is according to the desired characteristic impedance decision of radio frequency connector.The composite material that solid dielectric insulation is selected polytetrafluoroethylene or polyethylene from high pressure process for use or is made up of polytetrafluoroethylene and plastics, gas-insulated medium is selected air for use.
The present invention has following beneficial effect:
1, can compare with the similar radio frequency connector that the contact pin of φ 0.8～φ 1.6 cooperates with existing, transmission performance increases substantially, and reflection loss reduces significantly, is example with the radio frequency connector in characteristic impedance 75 Europe, and reflection loss is reduced to-below the 25dB.
2, good with the coupling of cable television system equipment such as splitter, distributor, trunk amplifier, significantly reduced the debugging work load of engineering.
3, only the structure of dielectric is improved and the raw material of dielectric are easy to obtain, thereby be convenient to processing and fabricating, produce in batches.
