The present invention aims to obtain a connector device for an electric machine tool providing excellent vibration resistance and high safety, while allowing ease of disassembling and reassembling.The present invention provides a connector device removably connecting an internal wire of an electric machine tool comprising: a male connector 1 comprising multiple male contact pieces 11n, and a male contact piece retention portion 12 retaining the multiple male contact pieces 11n; and a female connector 2 comprising multiple female contact pieces 21n, and a female contact piece retention portion 22 retaining the multiple female contact pieces 21n. The male contact piece retention portion 12 has multiple concentrically formed convex portions 12n. The multiple male contact pieces 11n are mounted on an outer circumferential wall of the convex portions 12n, and arranged concentrically, with a tip end thereof being inclined toward the center of the convex portions 12n. The female contact piece retention portion 22 has concentrically formed multiple concave portions 22n. The multiple female contact pieces 21n are mounted on an inner circumferential wall of the concave portions 22n, and arranged concentrically, with a base end thereof being inclined toward the center of the concave portions 22n. The convex portion 12n, to which the male contact piece 11n is mounted, and the concave portion 22n, to which the female contact piece 21n is mounted, are brought into contact and tightly fitted with one another.
