Abstract
The invention relates to an N type inserting hole contact element radio-frequency connector connected with a 7/8' coaxial cable in a matching mode. Field rapid installation can be achieved, and based on the fact that the N type inserting hole contact element radio-frequency connector is connected with a smooth pipe 7/8' coaxial cable in a matching mode, the N type inserting hole contact element radio-frequency connector can further be connected with multiple kinds of ripple pipe 7/8' coaxial cables in a matching mode. The N type inserting hole contact element radio-frequency connector connected with the 7/8' coaxial cable in the matching mode comprises a first outer conductor and a second outer conductor, the second outer conductor is arranged on one side of the first outer conductor, an inner conductor is arranged above the first outer conductor, a spring washer is arranged between the first outer conductor and the inner conductor, and the tail portion of the first outer conductor is an inclined face.
Description
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 of coaxial cable that connects 7/8.
Two, background technology:
In background technology, along with the fast development of mobile communication cause, the demand of the antenna feeder cable of, low-loss large to power capacity, low intermodulation also increases day by day.Therefore as first-selected size 7/8 " coaxial cable use amount in signal transmission system grows with each passing day.Simultaneously the installment and debugging of antenna-feedback system all carries out in the open air, the first-selection when therefore being convenient to the open-air connector of installing and being also antenna-feedback system and selecting connector.
Present 7/8 " coaxial cable can be divided into according to the shape of outer conductor bellows and the large class of plain tube two.But due to different cable manufacturers produce 7/8 " corrugated cable size difference to some extent all, and plain tube has larger different from corrugated cable in shape especially.Therefore, although be all 7/8 " coaxial cable, due to difference and the connector construction restriction of cable dimension, the cable produced of different manufacturers all needs to have a kind of connector corresponding with it basically.Also there is not in the market the connector that can connect simultaneously plain tube and two kinds of dissimilar cables of bellows.
L29, N Connector connect the superior characteristics such as reliable (screw-type connections), stable, power capacity is large, 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
Existing connect 7/8 " the N-type jack contact radio frequency (RF) coaxial connector of coaxial cable; 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 installation and the replacing in field.
Three, summary of the invention:
The present invention is in order to solve the weak point in the above-mentioned background technology, also can connect multiple bellows 7/8 when providing a kind of and connecting 7/8 " the N-type jack contact radio frequency connector of coaxial cable; it can realize open-air Fast Installation, and based on connecting plain tube 7/8 " coaxial cable " coaxial cable.
For achieving the above object, the technical solution used in the present invention is:
" the N-type jack contact radio frequency connector of coaxial cable; comprise outer conductor one and outer conductor two; outer conductor two is arranged at outer conductor side one by one; it is characterized in that: outer conductor one top is provided with inner wire; be provided with spring washer between outer conductor one and inner wire, outer conductor one afterbody is the inclined-plane a kind ofly to connect 7/8.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
1, be convenient to open-air the installation
Because installation, the debugging of antenna-feedback system are all carried out in the open air, and be positioned at tens meters even on the steel tower of hundreds of rice, 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.The present invention adopts by forward and backward two body structures dimerous, connector is installed chaotic degree because part causes too much reduce to minimum; And the present invention adopts the attaching mode, as long as use two spanners just can install, so 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 excellent electrical properties, and can reach 10 years the open-air useful life of cable assembly, makes the user without any trouble and worry.
Different cable manufacturer production 7/8 " the corrugated coaxial cable size difference mainly concentrates on the diameter of dielectric, outer conductor, oversheath; due to clamping structure of the present invention, make to different cable manufacturer production 7/8 " coaxial cable has extremely strong compatibility.

Five, embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the present invention includes outer conductor 1 and outer conductor 27, outer conductor 27 is arranged at outer conductor one 2 one sides, and outer conductor one 2 tops are provided with inner wire 3, be provided with spring washer 4 between outer conductor 1 and inner wire 3, outer conductor one 2 afterbodys are the inclined-plane.
Referring to Fig. 2, the present invention adopts outer conductor 27 and common formation of spring washer 4 to support, because aluminium and copper all have ductility preferably, cable is in penetrating process, outer conductor one 2 inwalls, spring washer 4 circles that outer conductor one 2 afterbody beveled top ends will be squeezed into cable are close on the arc surface of outer conductor 27, by outer conductor one 2 afterbody inclined-planes, spring washer 4 and the common clamping cables outer conductor 12 of outer conductor 27.No matter be light face or corrugated cable, no matter also the outer conductor of cable is aluminium matter or copper, can opens smoothly and fit and step up cable outer conductor, efficiently solve different cables and can't adopt Same Part to clamp the difficult problem of outer conductor.Referring to Fig. 5, the present invention adopts the mode on outer conductor one 2 afterbody inclined-planes, in the process that outer conductor 1 and outer conductor 27 are tightened, existence due to spring washer 4, larger pressure can be provided, connect more reliably, and the electrical performance indexes of connector be improved great role is also arranged.In the cable outer conductor 12 that insertion is opened on the top on outer conductor one 2 inclined-planes, can make connector 8 reach the classification of waterproof of IP68 after connecting with cable.Conventional by the sealed ring deformation sealing owing to being different from, so this sealing means and cable dimension are irrelevant, connect any producer 7/8 " coaxial cable can reach good sealing effectiveness equally.
