Abstract
The utility model relates to an N-type jack contactor radio frequency connector for assembling a 7/8' coaxial cable. The connector can achieve fast field assembly, and can be assembled with various corrugated tube 7/8' coaxial cables on the basis of assembling a plain tube 7/8' coaxial tube. The connector comprises external conductors I and II, wherein the external conductor I is arranged on one side of the external conductor II; an inner conductor is arranged above the external conductor I; a spring gasket ring is arranged between the external conductor I and the inner conductor; and the tail of the external conductor I is an inclined plane.
Description
One, technical field:
The utility model relates to a kind of radio frequency connector, especially relates to a kind of " N type jack contact radio frequency connector of coaxial cable that connects 7/8.
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 as first-selected size 7/8 " 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.
Present 7/8 " coaxial cable can be divided into bellows and plain tube two big classes according to the shape of outer conductor.But since different cable manufacturers produce 7/8 " corrugated cable size difference to some extent all, and plain tube has bigger different with corrugated cable in shape especially.Therefore, though all be 7/8 " coaxial cable because the difference of cable dimension and connector construction restriction, the cable that different basically manufacturers produce all needs a kind of connector correspondence with it.Also there is not the connector that can connect plain tube and two kinds of dissimilar cables of bellows simultaneously in the market.
L29, N Connector connect 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
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, 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 the installation and the replacing in field.
Three, utility model content:
The utility model 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 realizing above-mentioned purpose, the technical scheme that the utility model adopts 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, is provided with spring washer between outer conductor one and the inner wire, and outer conductor one afterbody is the inclined-plane that a kind ofly connects 7/8.
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; And be positioned on the iron tower of tens meters even hundreds of rice; 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 adopts by forward and backward two body structures dimerous, connector is installed chaotic degree because of part causes too much reduce 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 excellent electrical properties, and can reach 10 years the open-air useful life of CA cable assembly, makes the user not have 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; because the clamping structure of the utility model, make to different cable manufacturer production 7/8 " coaxial cable has extremely strong compatibility.

Fig. 1 is the structural representation of the utility model;
Fig. 2 connects the sketch map behind the cable for connector;
Fig. 3 is the structural representation of inner wire;
Fig. 4 is the structural representation of spring washer;
Fig. 5 is the structural representation of the outer conductor one on inclined-plane for afterbody;
Fig. 6 is the structural representation of outer conductor two.
Among the figure, 1-insulated support, 2-outer conductor one, 3-inner wire, 4-spring washer, 5-spring leaf, 6-seal, 7-outer conductor two, 8-connector, 9-cable inner conductor, 10-cable, 11-cable insulation, 12-cable outer conductor.
Five, embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6; The utility model comprises outer conductor 1 and outer conductor 27; Outer conductor 27 is arranged at outer conductor one 2 one sides; Outer conductor one 2 tops are provided with inner wire 3, are provided with spring washer 4 between outer conductor 1 and the inner wire 3, and outer conductor one 2 afterbodys are the inclined-plane.
Referring to Fig. 2; The utility model adopts outer conductor 27 and spring washer 4 common formation to support; Because aluminium and copper all have ductility preferably; Cable is in penetrating process, and 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 outer conductor 27 common clamping cables outer conductors 12.No matter be light face or corrugated cable,, can both open applying smoothly and step up cable outer conductor, efficiently solve different cables and can't adopt same part to clamp the difficult problem of outer conductor no matter also the outer conductor of cable is an aluminium matter or copper.Referring to Fig. 5, the utility model adopts the mode on outer conductor one 2 afterbody inclined-planes, in the process that outer conductor 1 and outer conductor 27 are tightened; Because the existence of spring washer 4; Bigger pressure can be provided, connect more reliably, and the electrical performance indexes of connector 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 after connecting, reach the classification of waterproof of IP68 with cable.Owing to be different from and conventional lean on the sealing ring deformable seal, thus this sealing means and cable dimension have nothing to do, connect any producer 7/8 " coaxial cable can both reach good sealing effectiveness equally.
