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

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 steel tower of tens meters even 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 exactly the simple and reliable connected mode that gets, all can not adopt as modes such as welding.This patent product adopts by forward and backward two body structures dimerous, connector is installed chaotic degree because part causes too much drop to minimum; And the utility model patented product 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

The connection of whole cable assembly is very reliable behind this connector connecting cable, and electric property is extremely good, and can reach 10 years the open-air useful life of cable assembly, so that the user is without any trouble and worry.

Different cable manufacturer production 1/2 " the corrugated coaxial cable size difference mainly concentrates on the diameter of dielectric, outer conductor, oversheath; because the special clamping structure of the utility model patent to different cable manufacturer production 1/2 " super flexible cable has extremely strong compatibility.

3, unique internal structure design

The utility model patent 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 novel dielectric material and unique internal structure to make the utility model patent have good sealing property, mechanical performance and third order intermodulation.

Five, embodiment:

Referring to Fig. 1-Figure 10: a kind of contact pin contacting piece RF coaxial connector of connecting cable, comprise outer conductor 1 and outer conductor 26, be provided with inner wire 3 on the inwall of described outer conductor 1, be provided with seal 1 between described outer conductor 1 and the outer conductor 26, one side of described inner wire 3 is provided with swivel nut 1, the two ends of described outer conductor 26 are respectively arranged with anchorage clip gripping member 5 and seal 28, also are provided with insulated support 2 on the described outer conductor 1.

The utility model patent adopts outer conductor 26 inner one section cooperation cable helical structure as support, because aluminium and copper all have preferably ductility, after opening, cable outer conductor 9 is close on the end face of outer conductor 26, by the common clamping cables outer conductor 9 of anchorage clip gripping member 5 afterbody arc surfaces and outer conductor 26 ends, see figure ten for details.No matter the outer conductor of cable is aluminium matter or copper, can both open smoothly and conform to arc surface, efficiently solves different cables and can't adopt Same Part to clamp the difficult problem of outer conductor.

The utility model patented product adopts anchorage clip gripping member 5 and is press-fitted outer conductor 1, and anchorage clip gripping member 5 afterbodys and outer conductor 26 end faces are done the structure of step, see Fig. 6 and Fig. 7 for details.In the process that outer conductor 1 and outer conductor 26 are tightened, because step can provide larger pressure, the top of anchorage clip gripping member 5 afterbody steps will head in the outer conductor that opens, and can make connector 10 be to reach after cable connects the classification of waterproof of IP68.Since seal 1 with sealed ring deformation in conventional outer conductor 1 and the process that outer conductor 26 is tightened seal, seal 28 cooperates the cable screw thread to be spun on the cable, be out of shape in the process that outer conductor 1 and outer conductor 26 are tightened cable and outer conductor 26 are sealed, so these connector 10 structural entity sealing means and cable dimension are irrelevant, connect any producer 1/2 " super flexible cable can both reach good sealing effectiveness equally.

Conventional connector generally is to adopt polytetrafluoroethylene to make (PTFE) for insulating supporting, but because the some shortcomings of polytetrafluoroethylene itself, and is poor etc. such as lower, the inapplicable mold pressing production of mechanical strength, resistance to elevated temperatures.The utility model patent then adopts various aspects of performance all to be better than the new insulation material of polytetrafluoroethylene---and TPX is used as the main support part (insulated support of inner wire, see Fig. 2 for details), and ingenious structural design in addition, not only make the inner wire of connector 10 obtain firm support, cooperate the interface waterproofing design of inner wire uniqueness so that connector 10 inside have good sealing, the electric property that most importantly TPX is stable makes connector obtain more superior and stable electric property; Thereby TPX can mold pressing process the cost that also reduces connector simultaneously, TPX is high grade of transparency crystallinity condensate, density is 0.82, at high temperature have quite high elongation at break and impact strength and superior creep resistant, fusing point is about 240 degree, deflection at high temperature is little, very suitable mould molding processing; TPX has excellent electric insulation character, and its dielectric strength reaches 65KV/mm, is excellent than PTFE and propylene, and dielectric constant is about 2.12, and dielectric absorption is very low; The water absorption of TPX is very low, only is 0.01, therefore water and steam is had high tolerance.

In the utility model patented product, another novel part is exactly seal 28, seal 28 does not still give cable with supplemental support, the more important thing is since its unique texture so that the position that connector connects in the process of connecting cable tail portion of connector and cable applies certain pressure, so not only connect reliably, and the third order intermodulation index raising of connector is had great role.
