The beneficial effects of the utility model are:
1), abandoned traditional inner wire brought such as assembly precision affixed with outer conductor bolt again after solid welding section by section
Cross low many defects.On the one hand, creative being replaced as signal transmission using radio frequency coaxial semi-rigid cable of this utility model
Traditional inner wire of mandrel, not only novel in design, also solve simultaneously the elongate inner conductor that habitually in the past must adopt be difficult to add
The problem of work, its processing and efficiency of assembling and cost have all obtained very big improvement.Because of the good rigidity of semi-rigid cable, this cable one
Aspect transmits microwave signal, is on the other hand also the centre of location axle of whole antenna structure, and then is conducive to of the present utility model
The formation of stiff shaft cored structure.Once the perpendicularity of centre of location axle is guaranteed, its follow-up processing and assembly precision are certainly
A step so can be risen.On the other hand, by the design using the inner wire of more piece and the segment design of outer conductor and assembling
Thought, spaced each insulating supporting of arranging in pairs or groups, not only effectively avoid the assembling that between conductor, mode connects for screw is brought by mistake
Difference problem, also effectively serves simultaneously and radially supports the dual mesh being dielectrically separated from adjacent conductor in internal and external conductor and axial direction
's.In addition, because radio frequency coaxial semi-rigid cable comes with the adapter of standard so that this cable is obtained with the axiality of adapter
Arrive guarantee, thus the mismachining tolerance problem that traditional welding structure is brought can be avoided.Before above-mentioned axiality is guaranteed
Put, when this cable is assembled with mounting seat, whole antenna modules are accurately positioned using radio frequency coaxial semi-rigid cable as mandrel,
Radio frequency coaxial semi-rigid cable is carried out precisely coaxial again between mounting seat with adapter, carries out the corresponding dress of each part afterwards again
Join, finally effectively guarantee practical set precision of the present utility model.
Prove through l-G simulation test, this utility model reasonable in design and practical, it is led solving in slim-lined construction
While body unmanageable problem, also can effectively ensure processing and the assembly precision of inner wire and outer conductor, its work pole
For reliable and stable.
2), as the further preferred scheme of said structure, the first inner wire can be regarded as independent inner conducting elements,
Second inner wire and the 3rd inner wire are integrally regarded as independent inner conducting elements, then by the 3rd inner wire regard as one independent
Inner conducting elements, all isolate each other in axial direction with corresponding insulating supporting between each unit.Second inner wire and the 3rd inner wire
Between affixed each other with screw thread cooperation, the 3rd inner wire then passes through the second inner wire insulating supporting, and in final screw thread cooperation the 4th
Conductor.For the first inner wire, then more is as the banding part of radio frequency coaxial semi-rigid cable and relative first inner wire relatively
The support support member of insulating supporting and use.Finally, then with the inner core-body of radio frequency coaxial semi-rigid cable pass through the first inner wire insulation
Support is to connect the second inner wire.By above-mentioned inner wire fit structure, on the one hand usual spiral shell is replaced with thread fiting mode
Nail fit system, to increase the assembly precision of equipment, on the other hand, by the detachable knot of the second inner wire and the 3rd inner wire
Structure, the welding between coming for the inner core-body of the second inner wire and radio frequency coaxial semi-rigid cable provides reliable approach.
3), double fastening structure of why the second outer conductor insulating supporting, allows for carrying out the first inner wire bottom
During the welding operation of end face and radio frequency coaxial semi-rigid cable cable body, dismounting in advance or prior second outer conductor of not installing is needed to insulate
Support, to provide the space of above-mentioned welding operation.Complete in welding and the first inner wire can with radio frequency coaxial semi-rigid cable cable body
After fixing, due to the installing space without the second outer conductor insulating supporting in axial direction, therefore pass through pipeline leakage plugging device formula
Second outer conductor insulating supporting, can diametrically realize the later stage assembling purpose of this insulating supporting, and its design is extremely ingenious.
4), the setting of insulating bar, allowing for radio frequency coaxial semi-rigid cable is directly through second after all only with inner core-body
Cable stiffness by itself at inner wire insulating supporting, therefore this support is often slightly inadequate.By the arrangement of insulating bar so that
At this, insulating supporting and respective cable " can be supportted " by the insulating bar of hard in the axial direction, and then ensure the compact of its assembling
Degree and work rigidity, the lifting of this assembly precision after also integrally assembling for the later stage provides basic guarantee.
5), when the 3rd inner wire and the 4th inner wire carry out Screw assembly, need to be fixed work to the 3rd inner wire
Industry, with ensure the 3rd inner wire assembling when do not turn round.The setting purpose of through hole is in that carrying out above-mentioned fixed operation
When, it is provided that fixed cylinder with spliced eye road, thus radially push against the axle body of the 3rd inner wire with the end face of fixed cylinder, its
Reasonable in design and reliability, can effectively guarantee itself fixing purpose in assembling for the 3rd inner wire.
