Board-to-board electrical connector assembly

摘要

An electrical connector assembly ( 1 ) includes a first connector ( 11 ) having a first insulative housing ( 111 ) receiving a plurality of first contacts ( 112 ) therein and a second connector ( 12 ) having a second insulative housing ( 121 ) receiving a plurality of second contacts ( 122 ) therein. The second housing defines a plurality of second passageways ( 123 ) for receiving the second contacts, each second passageway defining a guiding channel ( 1232 ) and a receiving channel ( 1231 ) communicating with the receiving channel, and the guiding channel having a restricting wall ( 1233 ) therein. The second contact defines a second contacting portion ( 1221 ) partially protruding into the guiding channel. When the two connectors are mated together, the first contact is inserted into the guiding channel and restricted by the restricting wall and the second contacting portion of the second contact protruding into the guiding channel.
