Abstract: A self-healing alloy contains 5 to 11% by weight of molybdenum (Mo), iron (Fe) as a remainder, and unavoidable impurities. A method for manufacturing the self-healing alloy includes heat treating the alloy or preparing an alloy raw material powder and sintering, homogenizing, and cooling the alloy raw material powder.

Abstract: Disclosed is a board-to-board-type connector including: a female connector holder having an upper surface with an engagement opening with which a plurality of female terminals are engaged in symmetrical rows; and a male connector holder having an upper rim from which an engagement protrusion protrudes such that a plurality of male terminals are arranged in symmetrical rows and engaged with the engagement protrusion to form electrical contact with the female terminals, the male connector holding being fitted to the engagement opening of the female connector holder, wherein the female terminal includes a U-shaped receiving portion accommodated in the engagement opening and first stopper protrusions protruding toward an inside of the engagement opening from intermediate portions of both side surfaces of the receiving portion, the male terminal includes a U-shaped insertion portion formed along an outer peripheral surface of the engagement protrusion and second stopper protrusions symmetrically protruding toward

Abstract: Disclosed is a connector for connecting boards that is provided with male and female terminals being coupled with each other, thereby preventing the separation of contact between the male and female terminals even upon application of impacts and avoiding the generation of bad contact caused due to heat or other factors.
