Patent ID: 7794288

Claim:
A connector comprising: a female-type first housing supporting first joining terminals; a male-type second housing supporting second joining terminals electrically connected to the first joining terminals, the second housing being inserted into the first housing to mate with the first housing; and a latch metal which is latched into slits extending in one direction perpendicular to a direction of mating of the first housing and the second housing and formed in the first housing, and biases the second housing in a direction perpendicular to both of the direction of mating and a direction of the slits, wherein any one of the first housing and the second housing includes tapered slit ribs extending in the direction of mating, the tapered slit ribs are formed at a predetermined rate of width change and a predetermined rate of angular change, any other one of the first housing and the second housing includes tapered slits which are provided at positions corresponding to the slit ribs and extend in the direction of mating of the first housing and the second housing, the tapered slits have a rate of angular change and a rate of width change which are respectively greater than the predetermined rate of angular change and the predetermined rate of width change of the slit ribs, and when the second housing is made to mate with the first housing, outer wall surfaces of the slit ribs are fitted into inner peripheral surfaces of the slits, and slits of the slit ribs become narrower, and the slit ribs are pressed to fit into the slits.
