The bent pin contact radio-frequency connector comprises an outer conductor 1, an outer conductor 2 and an outer conductor 3. A sealing ring 1 is arranged between the outer conductor 1 and the outer conductor 2. A sealing ring 2 is arranged between the outer conductor 2 and the outer conductor 3. The outer conductor 3 is provided with a sealing ring 3 and a spring gasket.

Description

A kind of curved formula contact pin contacting piece RF connector that connects 1/2 ＂ ring-type cable

One, technical field:

The utility model relates to a kind of radio frequency connector, especially relates to a kind of curved formula contact pin contacting piece RF connector that connects 1/2 ＂ ring-type cable.

Two, background technology:

In the background technology, along with the fast development of mobile communication cause, the demand of the antenna feeder cable of, low-loss big to power capacity, low intermodulation also increases day by day.Therefore 1/2 ＂ coaxial cable use amount in signal transmission system grows with each passing day.Installation of antenna-feedback system simultaneously and debugging are all carried out in the open air, the first-selection when therefore being convenient to the open-air connector of installing and also being antenna-feedback system and selecting connector for use.

The coaxial 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 ＂ ring-type cable dimension of producing difference to some extent all, and the ring-type aluminum pipe has bigger different with ring-type copper pipe cable in the use especially.Therefore, though all be the coaxial cable 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.Also there is not the connector that can connect ring-type aluminum pipe and two kinds of dissimilar cables of ring-type copper pipe simultaneously in the market.

L29 type connector connects superior characteristics such as reliable (screw-type connections), stable, power capacity is big, high pressure resistant, low-loss firm in structure with it and the sky, the feeder line cable that become high power capacity, low-loss, low intermodulation developed the first-selected interface during exploitation.

The existing L29 type contact pin contacting piece RF coaxial connector that connects 1/2 ＂ coaxial cable; 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 open-air installation and replacing.

In sum, connect the tangible deficiency of L29 type contact pin contacting piece RF coaxial connector existence of 1/2 ＂ coaxial cable at present.

Three, utility model content:

The utility model is in order to solve the weak point in the above-mentioned background technology; A kind of curved formula contact pin contacting piece RF connector that connects 1/2 ＂ ring-type cable is provided; It can realize open-air Fast Installation, and based on also connecting multiple ring-type copper pipe 1/2 ＂ coaxial cable when connecting ring-type aluminum pipe 1/2 ＂ coaxial cable.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:

A kind of curved formula contact pin contacting piece RF connector that connects 1/2 ＂ ring-type cable; Comprise outer conductor one, outer conductor two and outer conductor three; It is characterized in that: be provided with sealing ring one between outer conductor one and the outer conductor two; Be provided with sealing ring two between outer conductor two and the outer conductor three, outer conductor three is provided with sealing ring three and spring washer.

Compared with prior art, the advantage and the effect that the utlity model has are following:

1, is convenient to open-air the installation

Because the installation of antenna-feedback system, debugging are all 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 the simple and reliable connected mode that gets exactly, all can not adopt as modes such as welding.The utility model adopts by forward and backward two body structures dimerous, connector is installed chaotic degree because of part causes too much drop to minimum; And the utility model employing attaching mode, as long as use two spanners just can install, 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, crust; Because the attaching structure of the utility model, the feasible common ring-type cable of 1/2 ＂ to different cable manufacturer production has extremely strong compatibility.

Five, embodiment:

Referring to Fig. 1 to Fig. 9; The utility model comprises outer conductor 1, outer conductor 25 and outer conductor 36; Be provided with sealing ring 1 between outer conductor 1 and the outer conductor 25, be provided with sealing ring 29 between outer conductor 25 and the outer conductor 36, outer conductor 36 is provided with sealing ring 3 10 and spring washer 8.Referring to Fig. 2; The utility model adopts cable outer conductor 13, sheath 14 to cooperate with outer conductor 36, two end supports, and the cable trough puts spring washer 8; Utilize copper, aluminium to have good ductility; Be attached on the arc surface of spring washer 8 after cable outer conductor 13 opened, the arc surface of spring washer 8 and outer conductor 36 nose circle cambered surfaces are adjacent to, the clamp system of outer conductor 25 shell afterbodys and spring washer 8 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 8 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 25 crush seal circles 1, and outer conductor 25 and outer conductor 36 crush seal circles 29, cable outer conductor 13 and outer conductor 36 crush seal circles 3 10 are done sealing.Sealing ring one 7 deformable seals in the process that outer conductor 1 and outer conductor 25 are tightened; Sealing ring 29 deformable seals in the process that outer conductor 25 and outer conductor 36 are tightened; Sealing ring 3 10 cooperates the ring-type cable joint-box on cable; In outer conductor 36 shells and the process that cable sheath cooperates; Sealing ring 3 10 extrusions; Cable outer conductor 13 and outer conductor 36 are sealed, so this connector construction integral sealing mode and cable dimension are irrelevant, the 1/2 ＂ coaxial cable that connects any producer can both reach good sealing effectiveness equally.
