Abstract: A coupling spring portion 15 connecting a movable beam 13 and a fixed beam 14 is formed in a shape of extending toward a connector rear end in a curved manner, so that, even if a joined portion of the coupling spring portion 15 is disposed at an approximately central portion of the fixed beam 14, an insertion space for a connection object is secured sufficiently. Simultaneously, a distance X from a swinging center W of the movable beam 13 to a front side contact point 13a of the movable beam 13 and a distance Y there from to an actuator operating point Q are set to be approximately equal to each other, so that a contact pressure of the movable beam 13 to the connection object is kept approximately constant by causing an operation amount of the actuator 16 to the movable beam 13 and a working amount of the movable beam 13 at the front side contact point 13a to approximately coincide with each other.

Abstract: An electrical connector comprises a housing made of insulator and attached to a main circuit board, conductive contacts arranged in the housing, and an actuator provided to be rotatable to the housing for engaging with the conductive contacts and to take up first and second stations selectively for bringing each of the conductive contacts into press-contact with a corresponding one of connecting terminals on a circuit board member inserted into the housing in the second station and for causing each of the conductive contacts to get out of press-contact with the corresponding one of the connecting terminals in the first station, wherein the actuator is provided with a covering portion for concealing an end portion of each of the conductive contacts connected electrically with one of conductive circuit pattern portions provided on the main circuit board when the actuator is in the second station.

Abstract: A communication cable connector (1) is provided with a malfitting prevention member (10) that allows an associated communication cable plug (21) to be fitted into the communication cable connector (1) while preventing insertion of an unassociated communication cable plug (30) thereinto.

Abstract: Noise suppressing apparatus comprises a pair of case plates on which surface ferrite plates are secured, which are engaged with each other while a plate-shaped noise generating component such as a flexible printed circuit board or a flat cable is placed between them, so that the installation operation of the noise suppressing apparatus to the noise generating component is easier and the noise suppressing apparatus is thinner.
