[0015] As shown in Figure 2 and Figure 3 , the shell 110 comprises a bottom shell 111 and an upper cover plate 112.
[0016] The bottom shell 111 has an inner cavity with an open top, the inner cavity is in the shape of a cuboid, and each of the four corners of the bottom of the inner cavity is provided with a mounting limiting screw hole. The top of the bottom shell 111 is provided with a plurality of limiting screw holes. The periphery (front, rear, left and right) of the bottom shell 111 is provided with a connecting through hole and a mounting limiting screw hole, and the connecting through hole is communicated with the inner cavity.
[0017] The upper cover plate 112 is fixed on the top of the bottom shell 111 by screws. Specifically, the upper cover plate 112 is provided with a mounting and fixing screw through hole, which cooperates with the plurality of limiting screw holes on the top of the bottom shell 111 to realize detachable fixing with the bottom shell 111. In addition, the upper cover plate 112 is also provided with a mounting and fixing through hole for mounting the shell 110 to the applied position.
[0018] As shown in Figure 1 and Figure 3As shown, the first RF connector 120, the second RF connector 130, the third RF connector 140, and the fourth RF connector 150 are all SMA type connectors, and the four are fixed around the bottom shell 111 respectively.
[0019] Taking the fourth RF connector 150 as an example, it has four mounting holes for connecting the inner conductor and facilitating installation and positioning. The inner conductor extends into the inner cavity through the connecting through hole on the front side of the bottom shell 111. The positioning screw and fastener 151 are connected to the mounting positioning screw holes on the front side of the bottom shell 111 through the four mounting holes. See [reference needed]. Figure 2 This secures the RF connector to the bottom shell 111. The connection structure between the other three RF connectors and the bottom shell 111 is the same, and will not be described in detail here.
[0020] The dielectric circuit board 160 is a printed circuit board with the same shape and size as the inner cavity of the bottom shell 111. It is located in the inner cavity and has a mounting limit through hole at each of the four corners. It is fixed to the mounting limit screw holes at the four corners of the bottom of the inner cavity by screws and fasteners 167.
