Abstract
The utility model provides a punching-riveting embedded isolator, which comprises a load, two permanent magnets, two magnetic conducting wafers, two gyromagnetic ferrites, a central conductor, a temperature compensation sheet, a cover plate, a base plate and a cylindrical cavity. The punching-riveting embedded isolator mainly changes the integrated steel cavity of a conventional isolator into a split-type cavity formed by the base plate and the cylindrical cavity, changes the connection of the cover plate and the upper port of the cavity from screw thread fastening into riveting-and-pressing fastening, and can mold rapidly by punching and pressing. The punching-riveting embedded isolator has the advantages of simple and reasonable structure, convenient and fast manufacturing and processing, high assembling and debugging efficiency, good heat radiation performance, stable working performance, etc. and can be widely applied in equipment such as communication system, test system, radar, satellite communication, etc.
Description
Technical field
The utility model relates to the isolator that uses on a kind of communication apparatus, and particularly a kind of embedded isolator belongs to communication technique field.
Background technology
Widely used embedded isolator on the communication apparatus in the base station in the various mobile communcations systems, repeater, terminal and various communication apparatus and fields such as test macro and radar, satellite communication thereof mainly is made up of cavity, permanent magnet, magnetic conduction disk, gyromagnetic ferrite, center conductor, gyromagnetic ferrite, magnetic conduction disk, permanent magnet, temperature compensation sheet, load and cover plate.But existing embedded isolator, because its cavity is the monolithic construction of all steel, cavity is suitable for reading also to be provided with internal thread and to be used for installing and to have externally threaded cover plate, obviously there is complex structure, the requirement on machining accuracy height, shortcoming such as production efficiency is lower, the material because of its cavity is a mild steel again, heat dispersion is bad, can have influence on the service behaviour and even the operation of entire equipment stability of isolator.
Summary of the invention
The purpose of this utility model is in order to overcome the weak point that above-mentioned existing embedded isolator exists, and designs a kind of simple and reasonablely, production and processing is convenient and swift, assembling and debugging efficiency height, perfect heat-dissipating dash the embedded isolator of riveting.
Of the present utility model towards the embedded isolator of riveting, comprise load, two permanent magnets, two magnetic conduction disks, two gyromagnetic ferrites, center conductor, temperature compensation sheet and cover plate, it is characterized in that also comprising base plate and circular cylindrical cavity, the base of described circular cylindrical cavity is welded on the base plate, the madial wall suitable for reading of circular cylindrical cavity is provided with shoulder, described two permanent magnets, two magnetic conduction disks, two gyromagnetic ferrites, center conductor, the temperature compensation sheet is packed into behind the circular cylindrical cavity, cover plate is contained on the shoulder and with the inside riveting of lateral wall suitable for reading of circular cylindrical cavity on the cover board, load is welded on the base plate and is connected with a lead-out wire of center conductor makes isolated port, and two other lead-out wire of center conductor is made input port and output port respectively.
For the ease of assembling, can on base plate, be provided with circular cylindrical cavity location notch and load orientation groove, and on the base plate at circular cylindrical cavity location notch middle part, be provided with positioning boss, be provided with location hole with the circular cylindrical cavity bottom of positioning boss correspondence position.
For the ease of heat radiation and processing, described base plate is selected copper material or the moulding of aluminium punch process for use, and circular cylindrical cavity and cover plate are selected the moulding of permeability magnetic material punch process for use.
Of the present utility model towards the embedded isolator of riveting, owing to the split type cavity that the one-piece steel cavity is changed into by base plate and circular cylindrical cavity, and it is fastening to make suitable for reading being connected of cover plate and cavity into riveting by screw threads for fastening, and can utilize punching press or stretch can rapid moulding.Have simple and reasonablely, production and processing is convenient and swift, assembling and advantages such as debugging efficiency height, perfect heat-dissipating.This kind structural design can also realize the shared of most of parts, such as: just can use circulator and get on as long as change base plate.Be more convenient for like this part and half-finished buying, storage, stock.Can make material cost reduction by 25%, production efficiency raising 10% and the working stability performance of entire device better.Can be widely used in equipment such as communication system, test macro, radar and satellite communication.
