Abstract

A plug for provision of power includes a housing forming a receiving cavity with two opposite sites in a vertical direction which is compatible with a standard plug connector with twelve contacts on each site and a first and second rows of contacts on the sides while in diagonally symmetrical manner. Each contact includes a contacting section, and a connecting section for directly connecting to a corresponding wire. Each row of contacts is categorized with a pair of power contacts, a pair of grounding contacts and a specific contact without any high speed differential pair. Two pair of power contacts of both two rows are electrically connected together either via direct mechanical connection via vertical extensions or via indirect electrical connection via the latch which has a pair of side arms extending into the receiving cavity at two opposite transverse ends.
