The fixing member 2 is preferably made of rubber. After the fixing member 2 surrounds the RF connector port and is fixed to the RF connector through the first connecting end 200 and the second connecting end 220, the first connecting end 200 is connected to the limiting plate assembly 1. Figure 1 As shown, two sets of fixing parts 2 are respectively arranged at the front and rear port positions of the RF connector. After the limit plate is connected to the fixed base plate, the fixing parts 2 fix the RF connector. The front and rear ports of the SMA connector are connected by threaded screws. The fixing parts 2 can prevent the front and rear ports of the SMA connector from rotating, which may cause a connection failure.
[0037] In this embodiment, it is preferred that the fixing member 2 is a one-piece structure when unfolded. Figure 3 As shown, the overall strength of the fixing member 2 is improved. When the fixing member 2 is fixed around the RF connector port, the second connection end 220 is connected to the first connection end 200 through the opening 211 by utilizing the material characteristics of the fixing member 2 itself.
