Abstract: The present invention provides a multi-pole electrical connector for which mounting on a printed circuit board is simplified and which may be made as a compact design.The multi-pole electrical conenctor of the present invention includes pieces divided into upper contact pieces and lower contact pieces which are respectively disposed in a main body in upper and lower stages. The respective contact pieces have contacts which correspond to external contacts of a printed circuit board and also have contacts which correspond to contacts of another multi-pole electrical connector. The multi-pole electrical connector may be mounted on a printed circuit board and connected to another multi-pole electrical connector by contacting the contacts of the multi-pole electrical connector with the contacts of the printed circuit board and the contacts of the other multi-pole electrical connector.
