A connector 11 including a flexible engagement piece 25 which has a base end supported like a cantilever in a terminal accommodation chamber 17 for accommodating a terminal fitting and is thus deformable elastically, and has a free end 27 with which the terminal fitting to be inserted into the terminal accommodation chamber 17 is engaged, wherein the flexible engagement piece 25 having a beak 31 formed on the free end 27 to be engaged with the terminal fitting takes a shape of an inclined surface 29 having a height of a top portion 41 increased gradually from the free end 27 toward the base end in such a manner that a maximum shear area is obtained by a shear force of the terminal fitting.
1. A connector, comprising:
a flexible engagement piece which has a base end supported like a cantilever in a terminal accommodation chamber for accommodating a terminal fitting so as to be deformable elastically, and has a free end with which the terminal fitting to be inserted into the terminal accommodation chamber is engaged,
wherein the flexible engagement piece includes a beak formed on the free end to engage the terminal fitting therewith, the beak having an inclined uppermost surface with which a thickness of the beak gradually increases from the free end of the flexible engagement piece toward the base end thereof in such a manner that a maximum shear area is obtained by a shear force of the terminal fitting.
2. The connector according to claim 1 , wherein the inclined uppermost surface is set to have an inclination angle along a track of a shear fracture in the beak.
