Bidirectional duplex electrical connector having high and low surfaces and combination of the bidirectional duplex electrical connector and docking electrical connector

An electrical connector, with which a docking electrical connector can be bidirectionally docked for connection, the electrical connector comprising:

• a plastic seat;
• a connection portion, wherein the connection portion is provided with top and bottom surfaces and connected to and disposed on a front end of the plastic seat;
• a connection slot provided on the front end of the plastic seat, wherein the top and bottom surfaces of the connection portion are provided in the connection slot;
• and
• two rows of terminals, wherein each of the terminals is provided with an electrical connection point , the electrical connection points of the two rows of terminals are respectively arranged on the top and bottom surfaces of the connection portion;
• characterized in that the connection slot allows the docking electrical connector to be dual-positionally and bidirectionally inserted for positioning, the top and bottom surfaces of the front section of the connection portion are two front-section surfaces, the top and bottom surfaces of the rear section of the connection portion are provided with two rear-section surfaces and are closer to the plastic seat than the front section, the rear-section surface of one of the top and bottom surfaces of the connection portion projects much more than the entire front-section surface of the corresponding one of the top and bottom surfaces of the connection portion by a height so that a step is formed between the rear-section and front-section surfaces of each of the top and bottom surfaces of the connection portion.

A combination of an electrical connector and a docking electrical connector, the combination comprising:

• the docking electrical connector provided with an insulation seat and a metal housing covering the insulation seat, wherein the insulation seat is connected to and provided with at least one connection plate provided with one connection surface, and the connection surface is provided with at least one row of connection points;
• and
• the electrical connector comprising:
• a plastic seat;
• a connection portion, wherein the connection portion is provided with top and bottom surfaces and connected to and disposed on a front end of the plastic seat;
• a connection slot provided on the front end of the plastic seat, wherein the top and bottom surfaces of the connection portion are provided in the connection slot;
• and
• two rows of terminals, wherein each of the terminals is provided with an electrical connection point , the electrical connection points of the two rows of terminals are respectively arranged on the top and bottom surfaces of the connection portion;
• characterized in that the connection slot allows the docking electrical connector to be dual-positionally and bidirectionally inserted for positioning, the connection portion is provided with a front section and a rear section, the top and bottom surfaces of the front section of the connection portion are two front-section surfaces, the top and bottom surfaces of the rear section of the connection portion are provided with two rear-section surfaces closer to the plastic seat than the front section, and the rear-section surface of one of the top and bottom surfaces of the connection portion projects much more than the entire front-section surface of the corresponding one of the top and bottom surfaces of the connection portion by a height so that a step is formed between the rear-section and front-section surfaces of each of the top and bottom surfaces of the connection portion.
