Abstract
Abstract A lock eject mechanism for a pair of electrical connectors includes a first housing (210) for a first electrical connector (200); a lock eject unit (220) provided on opposite sides of the first housing; a second housing (110) for a second electrical connector (100); and a lock eject receiver (120) provided on opposite sides of the second housing for receiving the lock eject units for engagement. The lock eject unit includes a pair of lock eject levers (221) pivoted to opposite sides of the first housing and each having a lock portion (223) at its front section and a lock operation portion (222) at its rear section. The lock eject receiver includes a pair of lock members (121) for engagement with the lock portion of the lock eject levers to lock a plug-in condition between the first and second electrical connectors; a pair of guiding members (123) provided in the vicinity of the lock members for guiding the lock portions of the lock eject levers to the lock members for engagement when first and second electrical connectors are plugged in; and a pair of eject members (122) for exerting ejecting forces upon the lock portions when the lock operation portions are squeezed to pull the first electrical connector out of the second electrical connector.
