Description
Technical Field
The utility model relates to a microwave components and parts technical field especially relates to an circulator/isolator medium cover structure.
Background
Along with the development of large-scale construction of 5G in 2020, the number of base stations is greatly increased from 4 channels and 8 channels of 4G to 64 channels, the single-machine occupation amount reaches 192, and the requirement on a circulator/isolator is greatly increased.
The existing circulator/isolator generally adopts a medium sleeve structure as shown in fig. 1, namely a cylindrical sleeve structure, which is made of polytetrafluoroethylene and has certain elasticity, and is arranged in a medium sleeve hole position corresponding to a cavity to play a role of fastening a contact pin;
by adopting the existing medium sleeve with the annular sleeve structure as shown in fig. 1, a medium sleeve hole position needs to be reserved on the cavity of the circulator/isolator, certain requirements are required on the wall thickness and the size of the cavity, and under the large background that surface-mounted components tend to be miniaturized and lightened day by day, the existing medium sleeve structure is not beneficial to simplifying and reducing the cavity in the circulator/isolator assembly, so that the medium sleeve structure which is more suitable for future development, namely miniaturization and simplification is urgently needed in the field.
SUMMERY OF THE UTILITY MODEL
An object of the present invention is to provide a circulator/isolator medium sleeve structure to solve the above problems.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides an circulator/isolator medium cover structure, includes medium cover main part bearing structure, medium cover main part bearing structure includes hollow column main part and sets up in main part several supporting part all around (also can be called the extension), every all be provided with hollow cylindric protruding structure on the supporting part, protruding structural breach about being provided with and lining up, the position of breach is kept away from the center of main part, the middle hollow portion of main part is central through-hole, the middle hollow portion of protruding structure is the second through-hole.
In the utility model, the central through hole of the main body part is used for placing and positioning the magnet, and each supporting part is provided with a hollow cylindrical protruding structure for wrapping the contact pin, thereby preventing the electric arc generated in the air due to overhigh pulse energy and too close distance between the contact pin and the internal components of the circulator/isolator;
as a preferred technical scheme: the angle of the connecting line of every two convex structures and the center of the medium sleeve main body supporting structure is 0-360 degrees.
Compared with the prior art, the utility model has the advantages of:
1. can prevent the electric arc from generating in the air due to the over high pulse energy and the too close distance between the contact pin and the inner component of the circulator/isolator;
2. the structure is simple, the raw materials are easy to obtain and cheap, the reliability is high, the process is mature and stable, the structure can be directly formed by injection molding, and no post-treatment is needed;
3. the hollow cylindrical protruding structure is matched with the gap which is provided with a through upper part and a through lower part through reasonable tolerance, so that the medium sleeve structure can be well matched with the contact pin, and the stress of an internal component of the circulator/isolator can be released under the working conditions of temperature change, vibration, falling and the like of the circulator/isolator;
4. the adoption of the medium sleeve structure is beneficial to the miniaturization and the light weight of the cavity, saves the cavity raw material plate and further reduces the cost of the whole product.
