Connector and electronic device
A connector includes a first insulator, a second insulator, and a contact. The first insulator is formed in a rectangular shape and includes a pair of first side walls and a bottom wall. The second insulator extends along a longitudinal direction of the first insulator. The second insulator is partially positioned in a space surrounded by the pair of first side walls and the bottom wall and is movable relative to the first insulator. The contact is mounted on the first side walls of the first insulator and on the second insulator and includes an elastic portion. The elastic portion is located between the first insulator and the second insulator and connects the first insulator and the second insulator to each other. The second insulator and the elastic portion are spaced apart from the first insulator and face the bottom wall in a non-fitted state.
