Universal, voltage variable, safety enhanced electric connector

摘要

A universal, voltage variable, safety enhanced electric connector system is provided. Each connector in the system includes a housing, an electric plug and receptacle disposed at opposite side walls of the housing, and power supply circuit means disposed within the housing and connected between the electric plug and receptacle. The power supply circuit means includes a voltage transformer for converting an input power supply voltage into high and low voltage AC power supplies. It also includes the rectifier for converting AC power supply voltage into DC power supply voltage, as well as an AC voltage regulator, a DC voltage regulator and a DC output jack coupled to the rectifier. At least one insertion slot corresponding to one of the transformer voltage outputs in formed on a left side wall of the housing with a pair of metal contact plates provided therein. At least one metal blade is disposed and a right side wall of the housing for corresponding engagement with an insertion slot in another connector formed in accordance with the present invention. A plurality of electric connectors may be interconnected by inserting the electric plug of one to the electric receptacle of another and at least one metal blade of one connector to at least one insertion slot of another, such that the AC power supply voltage is at one connector is conveyed to other.
