Specifically, the hole pitch L of the adjacent openings 23 may range from 10mm to L40 mm.
In an embodiment of the present invention, please refer to fig. 4 to 5, the shielding bracket 20 is enclosed to form a mounting opening 24, a supporting member 25 is disposed in the mounting opening 24, and two ends of the supporting member 25 are respectively fixedly connected to two opposite sides of the shielding bracket 20.
In this embodiment, the shielding bracket 20 is ring-shaped, and the hollow portion of the shielding bracket 20 is the mounting opening 24. It can be understood that, since the shielding bracket 20 has a ring-shaped hollow structure, the shielding bracket 20 is easily deformed when being subjected to an external force, which is not favorable for the soldering operation of the shielding bracket 20 and the circuit board 200, and is easily defective. By additionally arranging the supporting member 25 in the mounting opening 24 of the shielding bracket 20 and connecting the two opposite sides of the mounting opening 24 on the shielding bracket 20 by the supporting member 25, the overall structural strength of the shielding bracket 20 can be improved, thereby avoiding the deformation of the shielding bracket 20 and ensuring that all parts of the shielding bracket 20 can be accurately mounted when the shielding bracket 20 is welded on the circuit board 200.
