Second electrical connector and connector assembly

Abstract

This invention provides an electrical connector assembly with smooth terminal mating and resistance to bending, as well as a first electrical connector and a second electrical connector. The first electrical connector includes a first insulating housing, a plurality of first conductive terminals, and a terminal stabilizer. The mating side of the first insulating housing forms a first mating cavity; the plurality of first conductive terminals are installed inside the first insulating housing, and the mating ends of the first conductive terminals protrude from the first mating cavity; the terminal stabilizer is movable in a front-rear direction within the first insulating housing; the terminal stabilizer has a plurality of terminal exposure holes to expose the mating ends of the first conductive terminals; the mating side of the terminal stabilizer has at least one pair of elastic locking structures, and an insertion space is provided between the pair of elastic locking structures. Each elastic locking structure includes at least one first locking claw extending away from the mating direction, and the first locking claw can lock onto the first insulating housing, thereby keeping the terminal stabilizer and the first conductive terminals in a fully mated position.
