Abstract
A connector assembly (10) having an all plastic retention system has a housing (16, 18) in which tines (40) extend from a surface (36) thereof axially along contact receiving passages (38, 58). Each split frustoconical tine (40) has two tine members (42, 44). A transverse rib (54) extends along a surface (36) of the housing between adjacent tine members (42, 44) of adjacent tines (40). Each tine member (42, 44) has a pair of vertical ribs (50) extending along the exterior surface thereof upward from the surface (36) of the housing and sharing a portion of its volume with the transverse rib (54). The vertical ribs (50) and transverse rib (54) promote flow of plastic into all regions of the mould during moulding and support a contact (52) upon insertion thereof. A contact (52) inserted from the rear face (34) causes tine members (42, 44) to move radially outward until a retention bead (72) passes through an orifice (48) then tine members (42, 44) return to an unbiased position and contact (52) is secured in the connector assembly (10) as retention bead (68) is positioned between an annular shoulder (74) and the ends (46) of tine members (42, 44).
