Description
Technical field
The utility model relates to a kind of encapsulating structure of microwave isolator, belongs 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 provide good magnetic loop, electric pathway and Mechanical Reliability for circulator or isolator; It is little to make circulator or isolator have a volume, and temperature stability is good, and it is little to insert loss, the good and reliability advantages of higher of electromagnetic performance.
At present the packaged type of existing isolator adopts one of three kinds: the 1) packaged type of housing and cover plate employing screw thread spinning; 2) the Double bottom plate adds the packaged type of middle casing up and down; 3) housing and cover plate adopt the packaged type of punching press embedding.All there is its structural deficiency in these assembling forms: adopt the spiral cover packaged type, housing inner edge and cover plate outer rim all need machining screw, have increased the machine work cost; Increase and adopt the Double bottom plate to add middle casing packaged type number of spare parts, cost increases, and is difficult to the flux path that provides good; Housing and cover plate adopt the packaged type of pressing embedding to need special pressing equipment and can't take apart and ressemble or repair.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of encapsulating structure of novel no cover plate microwave isolator is provided.
The purpose of this utility model is achieved through the following technical solutions:
The encapsulating structure of microwave isolator comprises housing and base plate, and characteristics are: described housing has sidewall and bottom surface, and is formed with circular cylindrical cavity, has outwards outstanding flange on the sidewall; Described base plate is a planar structure, on base plate, place even magnetic conducting strip, center conductor, microwave ferrite, temperature-compensating sheet and permanent magnet, housing tips upside down on the base plate, even magnetic conducting strip, center conductor, microwave ferrite, temperature-compensating sheet and permanent magnet are contained in the circular cylindrical cavity of housing, and, center conductor passes breach on the housing sidewall and links to each other with load on the base plate, and the hole of being passed on the shell flange by screw screws in the base plate, and housing and base plate are fixed.
Further, the encapsulating structure of above-mentioned microwave isolator, the material of described housing is steel or aluminium or copper.
Further, the encapsulating structure of above-mentioned microwave isolator, the material of described base plate is steel or aluminium or copper.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
This encapsulating structure does not need cover plate, and the parts in the housing are located by anchor clamps, assembles, encapsulates and debug, and housing and base plate adopt the screw connection between the two, assembles and encapsulate simple and reliable, is applicable to the large-scale production of isolator.The processing cost of housing and base plate is low, and housing adopts standard size, and general interchangeability is strong; Base plate can require to adopt different materials and installation dimension according to different heat radiations, reduces the stock, reduces risks.The utility model is a novel design, the cost of microwave isolator is significantly reduced, the assembling and debug simple to operation, the productivity ratio height, have simultaneously that volume is little, performance is excellent, bear advantages such as the big and temperature range of power is wide, can be rated as have novelty, the good technology of creativeness, practicality.
