The adapter 6 is sleeved on the conductive terminal 5 and received at the connection between the second connection cavity and the first connection cavity. One end of the adapter 6 is electrically connected to the conductive terminal 5, and the other end extends toward the third interface 13 and is partially exposed to the third interface 13.
