Description
Technical field
This utility model relates to radio frequency transmission technical field, is specifically related to a kind of connector for radio-frequency coaxial cable.
Background technology
Coaxial radio frequency cable is the cable of electromagnetic energy in transmission radio-frequency region, radio-frequency cable is indispensable element in various radio communications system and electronic equipment, it is widely applied with aspects such as broadcast, TV, radar, navigation, computer and instrument in radio communication, it follows coaxial line transmission theory, can be transmitted electromagnetic signal easily.The decay of radio-frequency cable and conductor, medium, physical dimension, the frequency of technique level and work is the most relevant, and especially physical dimension determines the attenuation loss of radio-frequency cable of a kind of standard specifications.
In some specific use occasion and product, in order to reach the pad value of requirement and the corresponding electric property such as standing wave and intermodulation, product can be designed to the cable of cable one section of smaller structure size of connection of one section of larger structure size, common practice is to terminate with a series of radio frequency connector pair two sections of different size cable junctions, is attached.Connector for radio-frequency coaxial cable, uses coaxial line transmission principle, is interconnected by the coaxial radio frequency cable of different-diameter, has low standing wave, low intermodulation, connects reliable, low cost and other advantages.But existing connector for radio-frequency coaxial cable structure is complicated, cost is high, and the defects such as adapter fault causes index defective easily occur.
Utility model content
For above-mentioned technical problem, the utility model proposes a kind of new connector for radio-frequency coaxial cable structure, ensure performance, index simultaneously, it is achieved changeover section is simplified, cost degradation and reduce the purpose of cost.
In order to realize above-mentioned technical purpose, this utility model adopts the following technical scheme that:
A kind of connector for radio-frequency coaxial cable, including: the inner wire of coaxial configuration, medium and outer conductor；Ecto-entad is followed successively by: outer conductor, medium, inner wire；Air dielectric gap is all left in inner wire two ends and cable junction；Misplacement space is left at described inner wire mid diameter transformation and between the transformation of outer conductor endoporus middle aperture.
A length of 0.1 ~ the 0.3mm in described air dielectric gap.
A length of 0.3 ~ the 0.5mm of described misplacement space.
It is welded to connect between described inner wire two ends and the cable inner core of different size.
It is provided with observation port by the welding hole of described inner wire.
Described inner wire and outer conductor all use brass material, and electroplate.
The beneficial effects of the utility model are:
This utility model connector for radio-frequency coaxial cable structure all leaves air dielectric gap, leaves misplacement space carry out electrical compensation, to obtain more preferable electrical specifications with at described outer conductor endoporus aperture transformation at described inner wire mid diameter transformation in described inner wire two ends and cable junction.
Accompanying drawing explanation

Fig. 2 is the structural representation of inner wire；
Wherein, 1 is inner wire, and 2 is medium, and 3 is outer conductor, and S1 is air dielectric gap, and S2 is misplacement space.
Detailed description of the invention
As it is shown in figure 1, a kind of connector for radio-frequency coaxial cable, including: the inner wire of coaxial configuration, medium and outer conductor；Ecto-entad is followed successively by: outer conductor, medium, inner wire；Air dielectric gap S1 is all left in described inner wire two ends and cable junction；At inner wire mid diameter transformation and leave misplacement space S2 at described outer conductor endoporus aperture transformation.
As the further improvement of technical solutions of the utility model, a length of 0.1 ~ 0.3mm of described air dielectric gap S1.
As the further improvement of technical solutions of the utility model, a length of 0.3 ~ 0.5mm of described misplacement space S2.
As the further improvement of technical solutions of the utility model, it is welded to connect between described inner wire two ends and the cable inner core of different size.
As the further improvement of technical solutions of the utility model, by the welding hole of described inner wire, it is provided with observation port.
As the further improvement of technical solutions of the utility model, described inner wire and outer conductor all use brass material, and electroplate.Silver coating excellent electric conductivity and be prone to welding, simultaneously can ensure product intermodulation performance.
Embodiment 1
As it is shown in figure 1, this utility model connector for radio-frequency coaxial cable structure all leaves about 0.3mm air dielectric gap in described inner wire two ends and cable junction carries out electrical compensation, to obtain more preferable electrical specifications.At described inner wire mid diameter transformation, transit out of with described outer conductor endoporus aperture, leave about 0.5mm misplacement space and carry out electrical compensation, to obtain more preferable electrical specifications.
As shown in Figure 2, cable inner core at described inner wire two ends with different size uses reliable welding manner, and it is provided with observation port by inner wire welding hole, for gas in the tap when welding, promote scolding tin flowing welding, with this, scolding tin capacity situation during observable welding simultaneously, ensures that welding sequence is reliable and stable.
Medium described in this utility model connector for radio-frequency coaxial cable uses incision technique after Vehicle Processing, is cut in half from centrage by medium, and the medium after incision can be directly clamped among on the inner wire having welded core, and this structure operation is convenient, simplifies assembly technology.
