Abstract
The invention provides a novel casing-free microwave isolator with external magnet, comprising an external permanent magnet, an internal permanent magnetic strip and a bottom plate, wherein the external permanent magnet in a segmented structure is arranged on the bottom plate and forms a cylindrical groove which is sequentially internally equipped with a microwave ferrite, a central conductor, another microwave ferrite, a uniform magnet conducting chip and the internal permanent magnetic strip, and a cover board is adsorbed onto the external permanent magnet; the back of the bottom plate is lined with a radiating bottom plate on which a load is mounted. Adopting a casing-free design, the isolator has no need of not only casing, but also thick internal permanent magnetic strips which are arranged vertically and symmetrically; the packaging structure leads to easy assembly, simple debugging and easy operation on the basis of not changing the performance of devices.
Description
Technical field
The present invention relates to a kind of novel casing-free microwave isolator with external magnet, belong to wireless communication technology field.
Background technology
The housing parts that are absolutely necessary in existing circulator and isolator, housing is being born functions such as mechanical support, encapsulation, magnetic conduction and conduction.Good encapsulation or assembling mode can be realized less outer magnetic resistance, make circulator or isolator adopt less permanent magnet and can operate as normal.Present existing Y shape knot goes in ring and the isolator assembling mode adopts following three kinds of modes: 1. housing and cover plate adopt the assembling mode of screw thread spinning; 2. the Double bottom plate adds middle casing with the fixing assembling mode of screw up and down; 3. housing and cover plate adopt the assembling mode of punching press embedding.
All there is its structural deficiency in above-mentioned assembling form: adopt the spiral cover assembling mode, magnetic and cover plate outer rim all need machining screw in the housing, have increased the machine work cost; And adopting the Double bottom plate to add the middle casing assembling mode except that number of spare parts increases, the inside dimension height is not easy to regulate; Housing and cover plate adopt the assembling mode of pressing embedding to need special pressing equipment and can't take apart and ressemble or repair.
The built-in permanent magnetic sheet placed of symmetry parts that in existing circulator and isolator, are absolutely necessary up and down, the wall of built-in permanent magnetic sheet and housing forms closed magnetic circuit, and provide sufficient quiescent biasing the action of a magnetic field to produce gyromagnetic effect in microwave ferrite, make the microwave signal transmission direction produce the rotation of forward and reverse isolation.Its structural deficiency is that built-in permanent magnetic sheet thickness is bigger, accounts for 1/3rd of whole isolated device height at least, makes existing circulator and isolator be unfavorable for miniaturization.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of novel casing-free microwave isolator with external magnet is provided.
Purpose of the present invention is achieved through the following technical solutions:
Novel casing-free microwave isolator with external magnet, comprise external permanent magnet, built-in permanent magnetic sheet and base plate, characteristics are: described external permanent magnet places on the base plate, external permanent magnet is segmentation structure, and formation cylinder shape groove, pack into successively in cylinder shape groove microwave ferrite, center conductor, microwave ferrite, even magnetic conducting strip and built-in permanent magnetic sheet are on the external permanent magnet and adsorb cover plate; The back side at described base plate is lined with radiating bottom plate, and load is installed on the radiating bottom plate.
Further, above-mentioned novel casing-free microwave isolator with external magnet, described radiating bottom plate is connected and fixed by screw and base plate.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
1. adopt no case design, isolator does not need housing not need the built-in thick permanent magnetic sheet of symmetry placement up and down yet; The inner face of external permanent magnet is the part on the face of cylinder, place central portions such as microwave ferrite around, central portions such as microwave ferrite fixing and placed in the middle, and additionally do not increase the thickness of device, can microwave ferrite, built-in permanent magnetic sheet and even magnetic conducting strip be located with the power that magnetic field own produces; External permanent magnet replaces housing, supports and absorption base plate and cover plate, to play the function of encapsulation, conduction and magnetic conduction;
2. no longer need housing, extra sidewall or side plate, reducing outer magnetic resistance, and reduced cost; Encapsulating structure makes on the basis that does not change device performance and assembles easily, debugging is simple, easy operating;
3. utilize external permanent magnet, save shell body, add a built-in permanent magnetic sheet, increase the debugging scope, improve rate of finished products; Cost is low, function is remarkable, and is ease in use.
