BOARD-TO-BOARD-TYPE CONNECTOR

摘要

According to the present invention, a board-to-board-type connector comprises: a female connector holder having an upper surface with an opening along which a plurality of female terminals are arranged into symmetrical rows; and a male connector holder which is fitted to the opening of the female connector holder, and which has an upper rim from which a protrusion protrudes such that a plurality of male terminals are arranged into symmetrical rows and engage with the protrusion to form electrical contact with the respective female terminals. Each of the female terminals has a U-shaped receiving portion accommodated in the opening, and first stopper protrusions protruding toward the inside of the opening from intermediate portions of both sides of the U-shaped receiving portion. Each of the male terminals has a U-shaped insertion portion formed along the shape of the outer surface of the protrusion of the male connector holder, and second stopper protrusions protruding toward the outside of the protrusion of the male connector holder from intermediate portions of both sides of the insertion portion. The female terminals are attached/detached to/from the male terminals by the elastic transformation of the first stopper protrusions and the second stopper protrusions. Consequently, the board-to-board-type connector of the present invention is configured such that the female terminals are symmetrically transformed in the left and right directions when the female terminals are attached/detached to/from the male terminals. Thus, stresses being applied to the female terminals during attachment/detachment are distributed in the left and right directions, and therefore the engagement between the female terminals and the male terminals is stably maintained even when the connector is used over a long period of time.
