The structure used for the locking spring is arranged on the bottom surface or the side wall of the housing, the locking spring is provided with a protruding locking arm; after the locking spring is installed, the pressure is applied to the components in the housing, so that the gap among the components is small, the contact is excellent, and the good magnetic flux, the electric pathway and the mechanical reliability are provided; and the packaging structure of the locking spring enables the cost to be remarkably reduced without changing the device performance and is very practical.
Description
Technical field
The utility model relates to a kind of microwave circulator of novel package structure, 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 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, housing inner edge and cover plate outer rim all need machining screw, 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.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of microwave circulator of novel package structure is provided.
The purpose of this utility model is achieved through the following technical solutions:
The microwave circulator of novel package structure, comprise housing and cover plate, described housing is formed with half and opens wide cavity, the sidewall of housing has breach, in half unlimited cavity of housing, place permanent magnet, even magnetic conducting strip, center conductor, microwave ferrite, temperature-compensating sheet and cover plate, center conductor passes that breach stretches out outside the chamber on the housing sidewall, characteristics are: on the cover board be pressed with locking spring, the end of described locking spring is the arm shape structure of hook-type, has the structure that matches with locking spring on the described housing, by the locking spring holddown plate, make each component packages in housing.
Further, the microwave circulator of above-mentioned novel package structure, the structure that matches with locking spring on the described housing is hole or groove or protrudes or depression, with the hook arm shape respective outer side edges of locking spring end.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
1. the structure of using for locking spring is set on the bottom surface of housing or sidewall, locking spring has the locking arm that stretches out, after locking spring is installed, parts in the housing are produced pressure, slit between can making it is little, contact good, for circulator and isolator provide good flux path, electric pathway and Mechanical Reliability;
2. the each several part of locking spring all in housing, does not increase the volume of circulator; The machining screw of housing inner edge and cover plate outer rim is saved in the application of locking spring, has reduced the machine work cost;
3. be easy to assembling and debugging, the encapsulating structure of locking spring makes the cost of microwave circulator significantly reduce on the basis that does not change device performance, is the new design of a practicality.
