In some embodiments, an apparatus can include a printed circuit board (PCB) that has layers and includes a first portion and a second portion. The first portion can have a data port and a power port. A first layer is associated with data of the first portion of the PCB, and a second layer is associated with power of the first portion of the PCB. The second portion can have a data port and a power port. A third layer is associated with data of the second portion, and a fourth layer is associated with power of the second portion. The first portion or the second portion can have vias defining an electromagnetic interference (EMI) shield. The apparatus can include a power filter and a data filter that can, respectively, isolate power and data of the first portion from the second portion.

The invention discloses a terminal and an electronic device having the same. The terminal includes a connecting part, a mounting part, and a fixing part along an insertion direction, wherein the connecting part is adapted to be connected to a jump wire of an electronic component, the mounting part has an outer profile matching with at least a portion of an inner profile of an insertion hole in a base, for restricting displacement of the terminal after being inserted into the insertion hole, and the fixing part is adapted to be threadedly connected with the a fixing member so as to connect the fixing part to a circuit board.
