A kind of N type radio frequency coaxial connector at novel protection cable welding positionTechnical field
The present invention relates to a kind of N type radio frequency coaxial connector, particularly to a kind of novel protection cable welding portionThe N type radio frequency coaxial connector of position, belongs to power domain.
Background technology
The coaxial connector of N-type connection semi-flexible cable is that the one of antenna equipment and calculator room equipment enforcement signal transmission is the most normalConnected mode, there is volume little, the advantage such as easy for installation, be generally made up of internal and external conductor and Supporting Media.
N-type connection at present is partly rubbed the coaxial connector of cable and is typically to be made up of outer conductor, Supporting Media and inner wire.EvenConnect device generally uses welding manner to be connected with cable, and junction uses heat-shrinkable T bush to be protected by, and this method junction is easyFracture, easily cause electrical property when rocking cable unstable, it is therefore desirable to the N-type radio frequency at a kind of novel protection cable welding positionCoaxial connector.
Summary of the invention
The present invention proposes the N type radio frequency coaxial connector at a kind of novel protection cable welding position, solves existingIn technology, N-type connects and partly rubs the coaxial connector welding position of cable and easily snap off, and easily causes electrical property unstable when rocking cableFixed problem, offers convenience to user.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The N type radio frequency coaxial connector at a kind of novel protection cable welding position of the present invention, including outer conductor, inner wire, absolutelyEdge medium, nut, sealing ring, insulation spacer and metallic cable protection set, one end of described metallic cable protection set and described spiral shellFemale connection, is provided with described dielectric, described nut and described outer conductor and connects between described outer conductor and described inner wire,One end of described outer conductor is provided with sealing ring, and the other end of described outer conductor is provided with insulation spacer.
As a preferred technical solution of the present invention, the protection of described metallic cable is set on outside cable welding mouthPortion, the protection of described metallic cable has put a milling limit for spanner position.
As a preferred technical solution of the present invention, described inner wire is connected with cable.
The present invention is reached to provide the benefit that: the N type radio frequency coaxial connector at this novel protection cable welding positionWelding position is protected by the improvement made to improving, and welding position is not easily broken, electric performance stablity when rocking cable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described hereinExecute example be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment 1
As it is shown in figure 1, the present invention provides the N type radio frequency coaxial connector at a kind of novel protection cable welding position, including outsideConductor 1, inner wire 2, dielectric 3, nut 4, sealing ring 5, insulation spacer 6 and metallic cable protection set 7, metallic cable is protectedOne end of set 7 is connected with nut 4, is provided with dielectric 3, nut 4 and outer conductor 1 and connects between outer conductor 1 and inner wire 2,One end of outer conductor 1 is provided with sealing ring 5, and the other end of outer conductor 1 is provided with insulation spacer 6.
Metallic cable protection set 7 is arranged on the outside of cable welding mouth, and metallic cable protection set 7 has a milling limit for spannerPosition, plays the effect of protection soldering opening, is easy to open metallic cable protection set 7, it is simple to repair.
Inner wire 2 is connected with cable, transmits signal.
Time specifically used, cable is connected with the outer conductor of connector, the current concentrated inner surface at outer conductor 1 and inner wireThe outer surface of 2, connector generally uses welding manner to be connected with cable, arranges metallic cable protection set 7, gold at the position of weldingBelonging to cable protective sleeve 7 to threaded with connector, metallic cable protection set 7 is wrapped at soldering opening, reduces its amplitude rocked,Play the effect of protection soldering opening, reduce the interference of the transmission to signal.
The present invention, the improvement that the N type radio frequency coaxial connector at this novel protection cable welding position is made is to weldingPosition is protected, and welding position is not easily broken, electric performance stablity when rocking cable.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be usedSo that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention'sWithin protection domain.
