Description
One, technical field:
The present invention relates to a kind of radio frequency (RF) coaxial connector, especially relate to a kind of 1/2 ＂ coaxial cable that connects
L29 type contact pin contacting piece RF coaxial connector.
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.
L29 type 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 L29 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 L29 type contact pin contacting piece RF coaxial connector that connects 1/2 ＂ coaxial cable is provided, 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 L29 type contact pin contacting piece RF coaxial connector that connects 1/2 ＂ coaxial cable, comprise outer conductor one and outer conductor two, described outer conductor one and outer conductor two are respectively arranged with spring washer and sealing ring one.
Be provided with insulating carriage on described outer conductor one.
The material of described insulating carriage is polytetrafluoroethylene.
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 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-Figure 10: a kind of L29 type jack contact radio frequency (RF) coaxial connector that connects 1/2 ＂ coaxial cable, comprise outer conductor 1 and outer conductor 25, sealing ring 1 and spring washer 7 are set between outer conductor 1 and outer conductor 25, be provided with sealing ring 28 on outer conductor 25, be provided with insulated support 3 on outer conductor 1, the axial both sides of insulated support 3 are provided with inner wire 1 and inner wire 22, and an end arranged outside of the present invention has internal thread, match with corresponding external screw thread.
Product of the present invention adopts cable outer conductor 10, cable jacket 12 to coordinate with outer conductor 25, two end supports, the cable trough puts spring washer 7, utilize copper, aluminium to have good ductility, after being opened, cable outer conductor 10 is attached on the arc surface of spring washer 7, the arc surface of spring washer 7 and outer conductor 25 nose circle cambered surfaces are adjacent to, and clamp system and the spring washer 7 of outer conductor one 4 shell afterbodys step up cable jointly, see figure ten for details.No matter the outer conductor of cable is aluminium matter or copper, can open smoothly the arc surface that conforms to spring washer 7, efficiently solves different cables and can't adopt Same Part to clamp the difficult problem of outer conductor.
Product of the present invention adopts outer conductor 1 and outer conductor 25 crush seal circles 1, cable outer conductor 10 and outer conductor 25 crush seal circles 28 to do sealing, sees figure ten for details.Sealing ring one 6 deformable seals in the process that outer conductor 1 and outer conductor 25 are tightened; Sealing ring 28 coordinates the ring-type cable joint-box on cable, in outer conductor 25 shells and process that cable cover(ing) coordinates, sealing ring 28 extrusions, cable outer conductor 10 and outer conductor 25 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.
3, unique internal structure design
The present invention has unique internal structure design, utilize cleverly axially dislocation compensation and radially the method such as impedance matching make it in the shortest length range, obtain optimized electric property, adopt simultaneously unique internal structure to make the present invention have good sealing property, mechanical performance.
It is insulating supporting that connector adopts polytetrafluoroethylene to make (PTFE), increases the insulating supporting position-limit mechanism; After the cable attaching, part 4 afterbody clamp systems compress cable outer conductor on the one hand, and front end face stretches into cable outer conductor on the other hand, guarantees the reliability and stability that support.
