A connector device includes a pair of first terminals, a second terminal, and a cover body. The first terminals are arranged in parallel. The second terminal includes a pair of contact points that are electrically connected to the respective first terminals, and is biased by a spring so that the contact points collectively sandwich the first terminals. The cover body made of a resin is attached to tip parts of the first terminals. The cover body includes first guide surfaces that have the contact points of the second terminal sliding thereon and guide the contact points in a direction for separating the contact points when the first terminals are connected to the second terminal. Thus, wear of the first terminals and the second terminal can be reduced.
