In addition, the area of the first board body 1 is effectively reduced, and the cost of the PCB assembly 100 is saved.

According to some embodiments of the present invention, the first board body 1 is formed with a plug hole 11, and the second board body 2 is formed with a plug pin 21 corresponding to the plug hole 11. The mating pins 21 and the mating holes 11 cooperate to connect the second board 2 to the first board 1. The jack hole 11 may be connected with a corresponding signal, such as a network signal, and the jack pin 21 may be connected with a corresponding signal, such as a control signal. For example, referring to fig. 1 and 2, the first plate 1 may have a substantially rectangular plate-like structure, a plurality of insertion holes 11 may be provided, the plurality of insertion holes 11 may be provided at intervals in the width direction of the first plate 1, and the insertion holes 11 may be formed as through holes penetrating through the thickness direction of the first plate 1.
