The N type inserting needle contact element radio-frequency connector connected with the 1/2' ring-shaped coaxial cable in the matching mode comprises a first outer conductor and a second outer conductor, a spring washer is arranged on the first outer conductor, a first sealing ring is arranged between the first outer conductor and the second outer conductor, a second sealing ring is arranged on the second outer conductor, an inner conductor is arranged above the first outer conductor, a polytetrafluoroethylene (PTFE) insulating support piece is arranged between the first outer conductor and the inner conductor, and a limiting mechanism is arranged on the PTFE insulating support piece.
Description
One, technical field:
The present invention relates to a kind of radio frequency connector, especially relate to a kind of N-type contact pin contacting piece RF connector that connects 1/2 ＂ ring-type coaxial cable.
Two, background technology:
In background technology, along with the fast development of mobile communication cause,, low-loss large 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.The installment and debugging of while sky, feedback system all carries out in the open air, and therefore being convenient to the open-air connector of installing is also sky, the first-selection when feedback system is selected connector.
The present 1/2 common ring-type coaxial cable of ＂ can be divided into according to the material of outer conductor ring-type copper pipe and the large class of ring-type aluminum pipe two.But the 1/2 ＂ coaxial cable size of producing due to different cable manufacturers is difference to some extent all.Therefore, although be all the coaxial cable of the 1/2 common ring-type of ＂, due to difference and the connector construction restriction of cable dimension, the cable of different manufacturers' productions all needs to have a kind of connector corresponding with it basically.Also there is not in the market the connector of the cable that can connect simultaneously different manufacturers' productions.
N Connector connects the superior characteristics such as reliable (screw-type connections), stable, power capacity is large, 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 1/2 common ring-type cable of ＂, because its internal structure is complicated, part is various, processing, the assembly difficulty of part are large, during production in enormous quantities, quality stability is relatively poor, so not only make the production cost of connector increase, more be not suitable for installing and changing.
Three, summary of the invention:
The present invention 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 also can connect multiple common ring-type 1/2 when connecting the common ring-type 1/2 coaxial aluminum pipe cable of ＂ " coaxial copper pipe cable.
For achieving the above object, the technical solution used in the present invention 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: be provided with spring washer on outer conductor one, be provided with sealing ring one between outer conductor one and outer conductor two, be provided with sealing ring two on outer conductor two, outer conductor one top is provided with inner wire, is provided with the PTFE insulated support between outer conductor one and inner wire.
Be provided with position-limit mechanism on the PTFE insulated support.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
1, be convenient to install
Carry out in the open air because installation, the debugging of the 1/2 common ring-type cable of ＂ are many, install for the ease of the field, at first just should reduce as far as possible the part of connector, connector and cable assembly are normal to be installed and changes and bring very large 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.Product integrative-structure of the present invention is installed chaotic degree with connector because part causes too much and is reduced to minimum; And the present invention adopts the attaching mode, gets final product installation as long as push to put in place, therefore is specially adapted to open-air fitting operation;
2, cable connects simple and reliable
After this connector connecting cable the connection of whole cable assembly is very reliable, and electric property is extremely good, and can reach 10 years the open-air useful life of cable assembly, makes the user without any trouble and worry.
The 1/2 common ring-type cable dimension of ＂ difference of different cable manufacturer production mainly concentrates on the diameter of dielectric, outer conductor, oversheath, due to special connecting structure of the present invention, make different outer conductor materials, the 1/2 common ring-type cable of ＂ of different cable manufacturer production has extremely strong compatibility.

Five, embodiment:
Referring to Fig. 1 to Fig. 9, the present invention includes outer conductor 1 and outer conductor 24, be provided with spring washer 6 on outer conductor 1, be provided with sealing ring 1 between outer conductor 1 and outer conductor 24, be provided with sealing ring 27 on outer conductor 24, outer conductor one 3 tops are provided with inner wire 1, are provided with PTFE insulated support 2 between outer conductor 1 and inner wire 1.referring to Fig. 2, the present invention adopts cable outer conductor 9, sheath 11 coordinates with outer conductor 24, two end supports, the cable trough puts spring washer 6, utilize copper, aluminium has good ductility, after being opened, cable outer conductor 9 is attached on the arc surface of spring washer 6, 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 the common clamping cables of spring washer 6, no matter the outer conductor of cable is aluminium matter or copper, can open smoothly the arc surface that conforms to spring washer 6, efficiently solving different cables can't adopt Same Part to clamp the difficult problem of outer conductor.The present invention 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 coordinates the ring-type cable joint-box on cable, in outer conductor 24 shells and process that cable cover(ing) 11 coordinates, sealing ring 27 extrusions, cable outer conductor 9 and outer conductor 24 are sealed, so this connector construction integral sealing mode and cable dimension are irrelevant, connect any producer 1/2 " coaxial cable can reach good sealing effectiveness equally.It is insulating supporting that connector adopts polytetrafluoroethylene to make (PTFE), increase the insulating supporting position-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.
