Yet; On the one hand, because the inner wire installing hole in the existing mounting structure is the stepped hole with two steps, is respectively applied for first stop sleeve and second stop sleeve are installed; Thereby this inner wire installing hole has increased the difficulty of processing of existing mounting structure and has increased production cost.On the other hand and since the shape and size of second stop sleeve must with the position and the depth dimensions Accuracy Matching of inner wire installing hole, thereby, increased the difficulty of processing of second stop sleeve and increased production cost.Again on the one hand, because the material behavior of polytetrafluoroethylene stop sleeve is softer, yielding, thereby, seriously influence the positional precision of inner wire and the dimensional accuracy of short transverse, thereby influenced the efficiency of assembling and assembling qualification rate of workshop.
Therefore, be necessary to provide a kind of mounting structure of hard connection inner wire of improved filter to overcome the problems referred to above.
The utility model content
The purpose of the utility model provides a kind of mounting structure of processing the hard connection inner wire of the filter simple, that electric property is stable, assembling is reliable and with low cost.
To achieve these goals; The utility model provides a kind of mounting structure of hard connection inner wire of filter; Comprise resonant cavity, resonant cavity cover plate, outer conductor and inner wire, the resonant cavity cover plate is fixed on the resonant cavity top, and outer conductor is fixed on the resonant cavity cover plate; Be provided with single stepped hole in the resonant cavity; One printed board is fixed on the step of single stepped hole, and inner wire passes outer conductor, resonant cavity cover plate and printed board successively and stretches into single stepped hole bottom, and inner wire is fixedly connected with printed board.
Preferably, the mounting structure of the hard connection inner wire of the filter of the utility model also comprises stop sleeve, and stop sleeve is set in inner wire upper end outer and stop sleeve and passes the resonant cavity cover plate and be sheathed in the outer conductor.
Preferably, inner wire comprises top cylinder, bottom cylinder and the limited step that connects top cylinder and bottom cylinder, the following end in contact of the upper surface of limited step and stop sleeve, the lower surface of limited step and printed board welding.
Preferably, the diameter of the bottom cylinder of inner wire is greater than the diameter of the top cylinder of inner wire.
Preferably, printed board is fixed on the step of single stepped hole through screw.
Compared with prior art, on the one hand, the stepped hole in the mounting structure of the hard connection inner wire of the utility model filter in the resonant cavity is single stepped hole, thereby, simplify the procedure of resonant cavity and saved production cost.On the other hand, because fixedly the parts of inner wire are printed board, and printed board is simple in structure, easy for installation, thereby, simplify difficulty of processing and saved production cost.Again on the one hand, because printed board is harder, thickness of slab is controlled easily, thereby, can well guarantee the relative altitude and the position of inner wire of inner wire top and resonant cavity cavity, thereby it is easy that production is assembled with respect to cavity, production cost reduces greatly.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
