It should be noted that the term "first" used in the first adapter assembly 10 and its components of the present embodiment is only used to distinguish the second adapter assembly 20 and its components, and has no other physical meaning. That is, the "first" used in the first adapter assembly 10 and its components in the present embodiment may be omitted; similarly, the second adapter assembly 20 and its components in this embodiment may be omitted from the use of "second".
As shown in fig. 4 and 5, the first adapter assembly 10 includes a plurality of first adapters 1 arranged in a row, and a first electrical connection interface is formed on each of two opposite sides of each first adapter 1. That is, the opposite sides of each first adaptor 1 have the same electrical connection interface.
