A structure capable of realizing multi-channel ultra-small space high and low frequency signal test comprises a shell 8, a radio frequency floating connector 7, a low frequency line 1 and a low frequency line connecting piece; two adjacent mounting holes are formed in the shell 8, the radio frequency floating connector 7 and the low-frequency line connecting piece are respectively arranged in the two mounting holes, and the low-frequency line 1 is connected to the low-frequency line connecting piece and led out from the outlet of the mounting holes.
The mounting hole provided with the radio frequency floating connector 7 is internally provided with threads, and the radio frequency floating connector 7 is arranged in the mounting hole through threaded connection.
