The aforesaid coupling assembling each connects socket's optimization arrangement scheme, and every connection socket's the arrangement position is all inequality, and the grafting direction is the same, and is specific, and each connection socket's grafting direction is all just to first module configuration bit, and the advantage of design like this lies in:

the arrangement positions of the connecting jacks are different, so that the signal connecting parts can be respectively plugged on the connecting jacks simultaneously without mutual interference, and the design of a mainboard module does not need to be adjusted due to the difference of the signal connecting parts;

the plugging directions are the same, so that the installation convenience can be further improved, different installation modes do not need to be considered due to different signal connection parts, and the purpose of selecting the socket/plug mode for adaptive connection is also realized.

Based on the arrangement of the connection sockets of the connection assembly, each connection socket corresponds to a certain space of the first module configuration position, and then in this space, the signal connection portion can be correspondingly arranged, so the first module configuration position can accommodate one or more signal connection portions, and each signal connection portion is connected with one connection socket of the connection assembly in an adaptive manner, for example, the connection sockets are three:

a signal connecting part can be arranged on one connecting socket, so that the other two connecting sockets are idle;

signal connection parts can be arranged on the two connection sockets, so that the other connection socket is idle;

signal connecting parts can be arranged on the three connecting sockets;

alternatively, the three insertion ends have different rectangular longitudinal distribution positions, one insertion end is close to the left side edge of the device shell, the other insertion end is close to the right side edge of the device shell, and the third insertion end is positioned between the two insertion ends;

alternatively, the three mating ends are similar to the combination of the two cases described above.

Furthermore, considering that the arrangement requirements of the signal connection parts corresponding to a certain type/function connection socket are different, on the basis of the above improved scheme, the following options are selected:

the connecting socket can be farther away from the space of the first module configuration position, so that more arrangement space is reserved for the functional circuit board;

the connecting socket can be deeper into the space of the first module configuration position, so that a shorter functional circuit board can be in adaptive connection with the connecting socket;

can be between connection socket and the mainboard module be to have elastic swing joint, for example be provided with the elastic component between connection socket and the mainboard module, the elastic component is when fully extending, can make connection socket visit the certain degree of depth in first module configuration position space, it is corresponding, the function circuit board is short-term, because connection socket visits the certain degree of depth in first module configuration position, consequently, also can with function circuit board adaptation connection, when the function circuit board is great, thereby also compressible elastic component guarantees the space of arranging of function circuit board.
