Abstract: A terminal-accommodation portion of a housing pierces a terminal-holding portion in a front-rear direction. A recess portion pierces the terminal-holding portion in a width direction and is opened upward. The recess portion communicates with the terminal-accommodation portions through an aperture formed in a bottom portion thereof. A latched portion of the terminal-accommodation portion protrudes in the recess portion. A protrusion portion of a retainer is provided with a latching portion and a retaining portion. When the protrusion portion is accommodated in the recess portion, the protrusion portion is positioned upward of the bottom portion of the recess portion. The latching portion is positioned downward of the latched portion. The retaining portion is positioned rearward of and faces a retained portion of a terminal.

Abstract: A connector that is attachable to an end of a flat cable and is connectable to a counterpart connector includes a housing having a plate-shaped portion and a terminal accommodating portion, and a socket terminal housed in the terminal accommodating portion. The socket terminal has a box portion in which a pin terminal of the counterpart connector is to be inserted, and a spring portion having a cantilever shape, the spring portion extending from the box portion and protruding onto the plate-shaped portion. The end of the flat cable is to be interposed between the plate-shaped portion and the spring portion of the socket terminal. The terminal accommodating portion receives part of force that the spring portion receives from the flat cable.

Abstract: A connector assembly comprises a first connector and a second connector. The first connector comprises a first housing provided with a stopper. The second connector comprises a second housing, a mating detecting member and a shift mechanism. The second housing is mateable with the first housing along a front-rear direction. The mating detecting member has an abutment portion. The abutment portion is movable in a direction intersecting with the front-rear direction by an operation of the shift mechanism. When the second housing is mated with the first housing under a state where the mating detecting member is positioned at a regulating position, the abutment portion abuts against the stopper, and the mating detecting member is moved from the regulating position toward an allowable position. The mating detecting member is positioned at the allowable position when a mating of the second housing with the first housing is completed.
