A connector and connector assembly

摘要

An object of the present invention is to prevent a receptacle from being rolled up without enlarging a circuit board connector. A male connector M is provided with a receptacle 10 in the form of a rectangular tube, and a female connector F is provided with a housing 40 fittable into the receptacle 10 from front. Mounting grooves 18 are formed by recessing both side walls 16 of the receptacle 10, fixing members 30 are mounted into these mounting grooves 18. The fixing members 30 are fixed to a circuit board 80 by soldering. A pair of left and right engaging projections 49 bulge out sideways from the opposite side surfaces of the housing 40. Engaging grooves 19 engageable with the engaging projections 49 as the two connectors F, M are connected to resist a tensile force acting when the housing 40 is pulled in a direction away from the circuit board 80 are formed by recessing the inner side surfaces of the both side walls 16 of the receptacle 10 at positions before the mounting grooves 18.
