US 10,707,600 B1 · Systems with electrical isolation between signal and power domains

Abstract

The system includes power-over-ethernet (PoE) sockets that interface to dedicated power and signal printed circuit boards. More particularly, the system separates power transmission circuitry from signal transmission circuitry for PoE arrays of RJ-45 sockets. The sockets include pins of different length to accommodate a stacked configuration of the power board and signal board. The pins corresponding to higher-voltage powers are a different length than lower-voltage signal pins. More than one PoE connector array may be coupled to a stack printed circuit boards, with pins of varying length, configured to engage with respective boards of the stack. The boards of the stack may be electrically isolated from each other, although the boards may be structurally engaged with each other.
