placing an inner conductor (70) in an inner hole of an insulating medium block (50), sleeving a first upper die (93) on the inner conductor (70), enabling the first upper die (93) to be in contact with a second step surface of the inner conductor (70), and then fixing the first upper die (93) on a press;

s3, compacting and fixing:

the press pushes the first upper die (93) to move, so that the inner conductor (70) moves towards the insulating medium block (50) until the conductor limiting ring (73) is in contact with the surface of the insulating medium block (50), and the first conductor bulge loop (71) and the second conductor bulge loop (72) are pressed into the insulating medium block (50);

s4, positioning a shell:

placing the connection housing (60) in the second lower die (92) and placing the connection housing (60) and the second lower die (92) in a coaxial arrangement;

s5, insulating installation:

placing the insulating medium block (50) which is completed by the combination in the S3 and the compression fixation in the connecting shell (60), arranging one end of the deformation groove (74) towards the connecting shell (60) to enter the connecting shell (60), and simultaneously placing a second upper die (94) on the insulating medium block (50);

s6, press-in connection:

placing the second upper die (94) on a press, and pressing the insulating medium block (50) into the connecting shell (60) through the press until the insulating medium block (50) cannot displace in the connecting shell (60), so that the shell bulge loop (64) is placed in the insulating medium block (50), and completing assembly;

s7, connection assembly:

connecting the SMA male head (80) to the second non-standard port (63) and extending the SMA male head (80) into the annular groove (65) so that the SMA male head (80) is in contact with the inner conductor (70), testing its port suitability;

s8, connecting the threaded sleeves:

in S7, after the port suitability test is completed, if the suitability of the assembly meets the standard, the screw sleeve (30) is sleeved from the second nonstandard port (63), the screw sleeve (30) is driven to move towards the first nonstandard port (62), when the screw sleeve (30) is sleeved on the connecting shell (60), the sealing ring (40) is guided into the sealing groove (61) from the first nonstandard port (62) to the second nonstandard port (63) to finish sealing, meanwhile, the first port (62) is connected with the standard DIN female head, the second port (63) is connected with the standard SMA male head (80), the electrical performance is detected, and if the suitability of the assembly does not meet the standard, the whole assembly is disassembled, and the corresponding part is replaced and reassembled.

9. The method for assembling a novel nonstandard port converter according to claim 8, wherein: in S6, press-in connection, performing spot check on the assembly in the step, respectively poking the inner conductor (70) from the first nonstandard port (62) and the second nonstandard port (63), observing whether the mechanical fixity among the inner conductor (70), the insulating medium block (50) and the connecting shell (60) meets the standard or not, and if the mechanical fixity among the inner conductor (70), the insulating medium block (50) and the connecting shell (60) does not meet the standard, pulling the inner conductor (70) outwards through clamping the inner conductor (70), pulling the insulating medium block (50) away from the connecting shell (60), separating the inner conductor (70) and the insulating medium block (50), and repeating S1 and insulating positioning; s2, installing a conductor; s3, compressing and fixing, replacing a new inner conductor (70) and an insulating medium block (50), and repeating S4 and positioning the shell; s5, insulating installation; s6, press-in connection is performed, and detection is performed in the step until the mechanical fixity among the inner conductor (70), the insulating medium block (50) and the connection shell (60) reaches the standard.

10. The method for assembling a novel nonstandard port converter according to claim 8, wherein: the second lower die (92) is provided with a positioning seat (921), and the positioning seat (921) and the second lower die (92) are coaxially arranged;

in S4, in the positioning of the shell, when the connecting shell (60) is placed, the second nonstandard port (63) of the connecting shell (60) is placed on the positioning seat (921).
