The waveguide transmission port interconnection structure includes a male connector 2 and / or a female connector 1; one end of the male connector 2 is provided with an internal thread, and a plurality of first connection holes are provided along the axial direction of the male connector 2; one end of the female connector 1 is provided with an external thread adapted to the internal thread of the male connector 2, and a plurality of second connection holes are provided along the axial direction of the female connector 1; wherein the male connector 2 and the female connector 1 form a male-female interconnection structure by means of a bolt 5 penetrating the first connection hole and the second connection hole; or, the male connector 2 and the male connector 2 form a double male interconnection structure by means of a bolt 5 penetrating the first connection hole and the second connection hole; or, the female connector 1 and the female connector 1 form a double female interconnection structure by means of a bolt 5 penetrating the first connection hole and the second connection hole.

[0042] Compared with the prior art, the waveguide transmission port interconnection structure provided by the present invention designs a universal male connector 2 and a female connector 1, which can be flexibly selected according to the connection structure of the waveguide transmission port through male-female interconnection, female-female interconnection and male-male interconnection.
