Description
Technical Field
The utility model relates to an antenna test technical field specifically is a rotary joint probe connection structure.
Background
In an antenna test system, a waveguide rotary joint is usually required to be manufactured to achieve the purpose of testing, so that cable connection cannot be used when waveguide cavities of different frequency bands are connected, and a connection structure is required to be manufactured. The conventional method is to use interference fit among the probe, the insulating sleeve and the inner diameter of the shaft sleeve to achieve the aim, and the method has the defects that mutual repulsion exists between assembly and precision, namely the assembly difficulty is high if the precision is ensured; if easy assembly is guaranteed, the precision is difficult to guarantee. Therefore, it is necessary to design a structure that is compatible with the antenna to meet the antenna test requirements.
