In a rear holder-attached connector (1), a relatively-thick protective rib (10) with a width (B) projects outwardly from opposite sides of a housing (2), and is disposed between upper and lower terminal receiving chambers (3). This width (B) is larger than a width of rear holders (20a, 20b), and thi
In a rear holder-attached connector (1), a relatively-thick protective rib (10) with a width (B) projects outwardly from opposite sides of a housing (2), and is disposed between upper and lower terminal receiving chambers (3). This width (B) is larger than a width of rear holders (20a, 20b), and this rib (10) protects the rear holders (20a, 20b) so that these rear holders, provisionally retained on the housing (2) within a metal-mold assembly, will not be discharged from the metal-mold assembly to drop, and will not be disengaged from the housing even upon contact with another housing. The provision of the protective rib (10) also serves to provide a good flow of a resin poured from the rear side of the housing (2) during the molding operation, and therefore thin partition walls, forming the terminal receiving chambers (3), can be positively molded, thereby enhancing the yield of the molded housings.

1. A connector, comprising: a housing having a terminal receiving chamber into which a connection terminal is insertable; a rear holder attachable to the housing, the rear holder being operative to be held on the housing in one of a provisionally-retained condition and a completely-retained condition, wherein when the rear holder is provisionally retained on the housing, the connection terminal is insertable in the terminal receiving chamber, and when the rear holder is completely retained on the housing, the connection terminal is retained by the rear holder in the terminal receiving chamber; and a protective rib formed on the housing in contact with said terminal receiving chamber, the protective rib having portions outwardly projected from opposite side surfaces of the housing, wherein a distance between outer end surfaces of the portions of the protective rib is larger than a width of the rear holder. 2. A connector, comprising: a housing having a terminal receiving chamber into which a connection terminal is insertable; a rear holder attachable to the housing, the rear holder being operative to be held on the housing in one of a provisionally-retained condition and a completely-retained condition, wherein when the rear holder is provisionally retained on the housing, the connection terminal is insertable in the terminal receiving chamber, and when the rear holder is completely retained on the housing, the connection terminal is retained by the rear holder in the terminal receiving chamber; and a protective rib formed on the housing, the protective rib having portions outwardly projected from opposite side surfaces of the housing, wherein a distance between outer end surfaces of the portions of the protective rib is larger than a width of the rear holder, wherein the rear holder includes opposite side walls having retaining holes which are respectively formed in inner surfaces thereof, and retaining pawls respectively formed on the inner surfaces and having forwardly downwardly-slanting surfaces, and wherein the housing has provisionally-retaining projections respectively formed on the opposite side surfaces of the housing at a rear end portion thereof and respectively engaged in the retaining holes of the rear holder when the rear holder is provisionally retained on the housing, the provisionally-retaining projections each has a plurality of tapering surfaces, tapering retaining steps are formed on the housing and are disposed respectively adjacent to the provisionally-retaining projections, the tapering retaining steps are respectively engaged with the retaining pawls, and a forwardly downwardly-slanting abutment surface for guiding the rear holder is formed on an upper surface of the housing at the rear end portion thereof. 3. A housing for a connector, said housing comprising: a plurality of terminal receiving chambers forming an upper row and a lower row; and a rib formed on the housing at a boundary region between the upper and lower rows of said terminal receiving chambers, said rib projecting outwardly from outer opposite side surfaces of said housing, said rib having a uniform thickness along the boundary and projecting regions.
