Abstract
The utility model discloses a tubular main rod assembly structure, which comprises an outer rod, an inner rod, an outer rod end insulating sleeve and an inner rod end insulating sleeve, wherein the outer rod is a tubular cylinder; an annular flange which is recessed to the axial center is arranged in the middle of the outer rod; the inner rod end insulating sleeve is arranged in the outer rod and positioned along the axial direction through the annular flange; the outer rod end insulating sleeve is arranged at the end of the outer rod; the inner rod passes through the outer rod end insulating sleeve; and one end of the inner rod is arranged in the inner rod end insulating sleeve. According to electromagnetic design and limiting principles, the tubular main rod assembly structure is designed as a simpler, convenient and universal assembly structure. Compared with the conventional assembly structure, the tubular main rod assembly structure has the advantages that: machining amount is reduced, the consumption of materials is reduced, electroplating process operation is facilitated, the universality of parts is improved, and production cycle is shortened.
Description
Technical field
The utility model relates to the electronic devices and components structure in the communications field, relates in particular to the mobile jib assembly structure in mixer, duplexer, the filter, specifically is a kind of tubulose mobile jib assembly structure.
Background technology
Mobile jib fit in existing mixer, duplexer, the filter, mobile jib modular construction are that integral installation is assigned in the cavity endoporus, and the cavity endoporus forms the design impedance with outer rod outer surface; Bar stretches into the adjusting of the length realization frequency of outer bar endoporus in utilizing simultaneously, and wherein outer bar one end is the connector link, also is stiff end; Other end tap link, outer bar middle part is provided with pcb board (T shape head) link, usually; Outer bar is to form with solid bar boring, because outer bar is long, thinner usually, has so just formed slender axles; Therefore when boring, possibly cause unstability, off-centre and machining accuracy to be difficult for guaranteeing; In case in next process, electroplate phenomenons such as plating is incomplete, pore will occur when endoporus is dark simultaneously, need make the electroplating technology hole in addition in the endoporus bottom usually and solve this problem, cause the processing waste.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, to provide simple in structure, and is easy for installation, can effectively reduce amount of machining and reduce the assembly structure of electroplating difficulty.Can reduce waste of material, shorten the tubulose mobile jib assembly structure in machine work cycle.
For realizing above-mentioned purpose, the tubulose mobile jib assembly structure of the utility model design comprises outer bar, interior bar, outer boom end insulating case and interior boom end insulating case; Said outer bar is a tubular cylinder; Outer bar middle part is provided with the collar flange that caves in to the axle center, and said interior boom end insulating case is installed in the outer bar and through the flange axial location, said outer boom end insulating case is installed in the end of outer bar; Interior bar passes outer boom end insulating case, and an end is installed in the interior boom end insulating case.
Above-mentioned outer bar is that seamless pipe is copper pipe or copper coating or silver-plated, forms through cutting, perforation processing.
Above-mentioned outer bar is provided with a connector connecting hole and a T shape link.
The flange at above-mentioned outer bar middle part forms through compacting.
The utility model adopts the seamless pipe of moulding according to Electromagnetic Design and spacing principle, and seamless pipe is copper pipe or copper coating or silver-plated; Process the function that outer bar is realized in the back through simple cutting and boring; Adopt pressing mode to generate the collar flange to the axle center depression simultaneously, the block piece of the axial location of boom end insulating case has reduced amount of machining, the supplies consumption of product in reaching as interior bar; Also reduce the plating difficulty, improved assembly performance and product stability.
