A connector terminal includes a front contact-point portion that wipes off foreign material by slidingly contacting a plug terminal and a rear contact-point portion that is conductively connected with the plug terminal. The front contact-point portion has a sliding edge that slidingly contacts the plug terminal. The rear contact-point portion includes a contact edge that is thinner than the sliding edge, has a sliding width that is less than that of the sliding edge, and is conductively connected with the plug terminal by passing a sliding path of the sliding edge. Therefore, it becomes less likely for the contact edge to contact foreign material adhered to a portion other than portions at the sliding path. Thus, conduction failure can be prevented. In addition, by providing the connector terminal, it is possible to provide a socket that can similarly prevent conduction failure caused by foreign material.

Electric connector

An electrical connector includes a terminal that includes a front terminal portion, and a rear terminal portion the contact position of which is located further from the insertion opening of the connector than the contact position of the front terminal portion, and that is electrically connected with a mating terminal as an object to be connected. The front terminal portion has a front elastic arm, and a front contact portion formed at the distal end of the front elastic arm, and the front contact portion has a front contact that comes into contact with the mating terminal, and a dummy contact that is located closer to the insertion opening of the connector than the front contact, and that wipes a foreign substance adhering to the mating terminal.

Electrical connector

A terminal of a connector includes two contact points, that is, a front contact point and a rear contact point. An angle formed by a line extending from an upper end of a rear terminal portion to the rear contact point and a direction in which the connector is inserted and removed is smaller than an angle formed by a line extending from an upper end of a front terminal portion to the front contact point and the direction in which the connector is inserted and removed. Thus, the insertion force used to insert the rear contact point can be reduced.

Terminal of a connector including two contact points

A socket terminal includes front and rear terminals. The front terminal includes a front contact-point portion that wipes off foreign material adhered to a terminal surface of a plug terminal. The rear terminal includes a rear contact-point portion that contacts the terminal surface wiped by the front contact-point portion. The socket terminal also includes a movable portion between a circuit-board connection portion and circuit board. The movable portion cancels a reduction in impedance of at least the front terminal and rear terminal for a transmission signal flowing from the circuit-board connection portion connected to the circuit board. This can provide a socket terminal allowing the rear contact-point portion to contact the terminal surface from which foreign material has been wiped off, and allowing impedance mismatching at a terminal transmission path to be eliminated; and to provide an electric connector including the socket terminal.
