An electrical connector housing, an electrical connector, and a connector assembly.

摘要

A split electrical connector housing (100) has a first housing (110) with contact compartments (111), and a second housing (120) to accommodate the first housing. The first housing (110) has a protrusion on the circumferential surface thereof. The second housing (120) includes an elastic arm (124). When the first housing (110) is inserted, and before it reaches a predetermined position, the elastic arm (124) is raised by the protrusion (112) and causes part of a contour of the second housing (120) to protrude. When the first housing (110) reaches the predetermined position, the elastic arm (124) is released from being raised by the protrusion (112).
