Abstract
Abstract In order to prevent deformation of contacts of connectors during their joining and to reduce the effort required for their connection without resorting to an increase in size, a cam-equipped connector has a facility for an intermediary joining. To prevent deformation of contacts, the female connector 10, equipped with a cam device 30, has protrusions 14 extending from the bottom surface 11a of a joining cavity 11 which are longer than contact sections of the male contacts. Cavities 24 intended for reception of the protrusions 14 are made in the joining surface 21 of the male connector 20. The protrusions 14 and the cavities 24 have maintaining steps 14a and maintaining lugs 24a for an intermediary joining of the connectors 10, 20.
