The purpose of this utility model is achieved through the following technical solutions: a kind of miniature ferrite circulator, includes lid, the first pole piece, Magnet, the second pole piece, the first ferrite component, center conductor, the second ferrite component, the 3rd pole piece and housing from top to bottom successively；Described housing forms containing cavity with lid, described magnet, the first pole piece, Magnet, the second pole piece, the first ferrite component, center conductor, the second ferrite component, the 3rd pole piece stacking arrange and are fixed in containing cavity, described housing sidewall offers breach, described center conductor is provided with pin and described pin stretches out from breach, the injection of described indentation, there has RTV silica gel to form RTV layer of silica gel, described RTV layer of silica gel closes accommodating cavity, and is fixed on the sidewall on the corresponding part magnet of gap position, ferrite and center conductor；The bottom surface of described lid inwall is provided with elastic component, and the parts in containing cavity are applied a downward power by described elastic component；Described housing top edge is provided with curved edges, and the lower limb of described lid is provided with and forms, with curved edges, the clinching interlocked, and forms interlocking structure between the clinching on lid and the curved edges on housing.
The quantity of described breach is three, and three breach are evenly distributed in housing sidewall.
Described housing is column type cavity structure.
The beneficial effects of the utility model are:
(1) this utility model adopts the indentation, there at housing to inject has RTV silica gel to form RTV layer of silica gel, described layer of silica gel closes breach, and it is fixed on the sidewall on the corresponding part magnet of gap position, ferrite and center conductor, seals accommodating cavity, it is possible to increase the electric property of circulator.Can play simultaneously and prevent magnet from attracting bushel iron pin and the effect preventing the water in air and dust from entering.
(2) being provided with elastic component in the bottom surface of lid inwall, the parts in containing cavity are applied a downward power by described elastic component.To keep the firm of its internal part to press, provide good electromagnetic touch for housing inner stacks mounting assembly.
(3) described housing top edge is provided with curved edges, and the lower limb of described lid is provided with and forms, with curved edges, the clinching interlocked, and forms interlocking structure between the clinching on lid and the curved edges on housing.Guarantee the machinery of Microwave Iron Oxide Elements and the reliable of electrical property, make conveniently to install simultaneously, and reduce production and processing cost.
