Description

Connect the N-type jack contact radio frequency connector of 1/2 ＂ ring-type coaxial cable

One, technical field:

The present invention relates to a kind of radio frequency connector, especially relate to a kind of N-type jack contact radio frequency 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 jack contact radio frequency (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 jack contact radio frequency connector that connects 1/2 ＂ ring-type coaxial cable is provided, it can realize open-air Fast Installation, and also can connect the multiple common ring-type 1/2 coaxial copper pipe cable of ＂ based on when connecting the common ring-type 1/2 coaxial aluminum pipe cable of ＂.

For achieving the above object, the technical solution used in the present invention is:

A kind of N-type jack contact radio frequency 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 sealing ring one between outer conductor one and outer conductor two, be provided with spring washer on outer conductor one, be provided with sealing ring two on outer conductor two, outer conductor one top is provided with inner wire, is provided with insulated support between outer conductor one and inner wire.

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, sheath, due to 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, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the present invention includes outer conductor 1 and outer conductor 24, be provided with sealing ring 1 between outer conductor 1 and outer conductor 24, be provided with spring washer 6 on outer conductor 1, be provided with sealing ring 27 on outer conductor 24, outer conductor one 3 tops are provided with inner wire 1, are provided with insulated support 2 between outer conductor 1 and inner wire 1.

Product cable outer conductor 9 of the present invention, outer conductor 1 coordinate with outer conductor 24, two end supports, the cable trough puts part spring washer 6, utilize copper, aluminium to have 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, and clamp system and the spring washer 6 of outer conductor one 3 shell afterbodys step up cable jointly.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 solves different cables and can't adopt Same Part to clamp the difficult problem of outer conductor.Referring to Fig. 2, the present invention adopts outer conductor 1 and outer conductor 24 crush seal circles 1, and cable outer conductor and part 4 extrusion sealing rings 27 are done 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 and process that cable outer conductor 9 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, the 1/2 ＂ coaxial cable that connects any producer can reach good sealing effectiveness equally.
