The N type pin contact radio frequency connector comprises an outer conductor 1 and an outer conductor 2, wherein the outer conductor is provided with a spring washer; a sealing ring 1 is arranged between the outer conductor 1 and the outer conductor 2; the outer conductor 2 is provided with a sealing ring 2; an inner conductor is arranged above the outer conductor 1; and a PTFE (polytetrafluoroethylene) insulation support piece is arranged between the outer conductor 1 and the inner conductor and is provided with a limit mechanism.
Description
One, technical field:
The utility model relates to a kind of radio frequency connector, especially relates to a kind of N type contact pin contacting piece RF connector that connects 1/2 ＂ ring-type coaxial cable.
Two, background technology:
In the background technology, along with the fast development of mobile communication cause,, low-loss big to power capacity, the sky of low intermodulation, the demand of feeder line cable also increase day by day.Therefore 1/2 ＂ coaxial cable use amount in signal transmission system grows with each passing day.Installation of sky, feedback system simultaneously and debugging are all carried out in the open air, and therefore being convenient to the open-air connector of installing also is sky, the first-selection when feedback system is selected connector for use.
The common ring-type coaxial cable of present 1/2 ＂ can be divided into ring-type copper pipe and ring-type aluminum pipe two big classes according to the material of outer conductor.But because the different cable manufacturers 1/2 ＂ coaxial cable size of producing difference to some extent all.Therefore, though all be the coaxial cable of the common ring-type of 1/2 ＂, because the difference of cable dimension and connector construction restriction, it is corresponding with it that the cable that different basically manufacturers produce all needs a kind of connector.The connector that does not also have the cable that can connect different manufacturers' productions simultaneously in the market.
N Connector connects superior characteristics such as reliable (screw-type connections), stable, power capacity is big, high pressure resistant, low-loss firm in structure and becomes the sky of high power capacity, low-loss, low intermodulation, the cable development of bursting, the first-selected interface during exploitation with it.
The existing N type contact pin contacting piece RF coaxial connector that connects the common ring-type cable of 1/2 ＂; Because its internal structure is complicated; Part is various, and processing, the assembly difficulty of part are big, and quality stability is relatively poor during production in enormous quantities; So not only make the production cost of connector increase, more be not suitable for installing and changing.
Three, utility model content:
The utility model is in order to solve the weak point in the above-mentioned background technology; A kind of N type contact pin contacting piece RF connector that connects 1/2 ＂ ring-type coaxial cable is provided; It can realize open-air Fast Installation, and when connecting the coaxial aluminum pipe cable of common ring-type 1/2 ＂, also can connect multiple common ring-type 1/2 " coaxial copper pipe cable.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of N type contact pin contacting piece RF connector that connects 1/2 ＂ ring-type coaxial cable; Comprise outer conductor one and outer conductor two; It is characterized in that: outer conductor one is provided with spring washer, is provided with sealing ring one between outer conductor one and the outer conductor two, and outer conductor two is provided with sealing ring two; Outer conductor one top is provided with inner wire, is provided with the PTFE insulated support between outer conductor one and the inner wire.
The PTFE insulated support is provided with position-limit mechanism.
Compared with prior art, the advantage and the effect that the utlity model has are following:
1, is convenient to install
Because how the installation of the common ring-type cable of 1/2 ＂, debugging are carried out in the open air; Install for the ease of the field; At first just should reduce the part of connector as far as possible, connector and CA cable assembly are normal to be installed and changes and bring very big inconvenience because part can be given too much; Secondly to use simple and reliable connected mode exactly, all can not adopt as modes such as welding.The utility model product integrative-structure is installed chaotic degree with connector because of part causes too much and is reduced to minimum; And the utility model employing attaching mode, get final product installation as long as push to put in place, therefore be specially adapted to open-air fitting operation;
2, cable connects simple and reliable
It is very reliable that this connector connects the connection of whole CA cable assembly behind the cable, and electric property is extremely good, and can reach 10 years the open-air useful life of CA cable assembly, makes the user not have any trouble and worry.
The common ring-type cable dimension of the 1/2 ＂ difference of different cable manufacturer production mainly concentrates on the diameter of dielectric, outer conductor, oversheath; Because the special attaching structure of the utility model; Make that 1/2 ＂ of different cable manufacturer production is common, and the ring-type cable has extremely strong compatibility to different outer conductor materials.

Five, embodiment:
Referring to Fig. 1 to Fig. 9; The utility model comprises outer conductor 1 and outer conductor 24; Outer conductor 1 is provided with spring washer 6, is provided with sealing ring 1 between outer conductor 1 and the outer conductor 24, and outer conductor 24 is provided with sealing ring 27; Outer conductor one 3 tops are provided with inner wire 1, are provided with PTFE insulated support 2 between outer conductor 1 and the inner wire 1.Referring to Fig. 2, the utility model adopts cable outer conductor 9, sheath 11 to cooperate two end supports with outer conductor 24; The cable trough puts spring washer 6; Utilize copper, aluminium to have good ductility, be attached on the arc surface of spring washer 6 after cable outer conductor 9 is opened, the arc surface of spring washer 6 and outer conductor 24 nose circle cambered surfaces are adjacent to; The clamp system of outer conductor one 3 shell afterbodys and spring washer 6 common clamping cables; No matter the outer conductor of cable is an aluminium matter or copper, can both open the arc surface that conforms to spring washer 6 smoothly, efficiently solves different cables and can't adopt same part to clamp the difficult problem of outer conductor.The utility model adopts outer conductor 1 and outer conductor 24 crush seal circles 1, cable outer conductor 9 and outer conductor 24 crush seal circles 27 to do sealing.Sealing ring one 5 deformable seals in the process that outer conductor 1 and outer conductor 24 are tightened; Sealing ring 27 cooperates the ring-type cable joint-box on cable; In outer conductor 24 shells and the process that cable cover(ing) 11 cooperates; Sealing ring 27 extrusions; Cable outer conductor 9 and outer conductor 24 are sealed, thus this connector construction integral sealing mode and cable dimension have nothing to do, connect any producer 1/2 " coaxial cable can both reach good sealing effectiveness equally.Connector adopts polytetrafluoroethylene to make (PTFE) and supports for insulation; Increase insulation support limit mechanism, after the cable attaching, outer conductor one 3 afterbody clamp systems compress cable outer conductor on the one hand; Front end face stretches into cable outer conductor on the other hand, guarantees the reliability and stability that support.
