Abstract: A connector includes a housing and a plurality of signal contacts and a plurality of ground contacts. Each contact includes a contact portion that contacts an object, a connection portion mounted on a substrate, and a fixing portion located between the contact portion and the connection portion in the vicinity of the connection portion. The signal contact and the ground contact are aligned and held in the housing, and the fixing portion is fixed to the housing. When the plurality of signal contacts are arranged between the ground contacts, at least two of the ground contacts are coupled and connected integrally or by a separate component, the coupling and connection being made in a section of each ground contact between one end (leading end) of the contact portion and the fixing portion, so that high-frequency transmission characteristics are improved.

Abstract: A multiconductor connector for high-speed transmission signal for connecting a plurality of paired cables includes an insulator plate having signal contacts on its upper and lower surfaces. The signal contacts are arranged in a row on each of the upper and lower surfaces to form pairs of the two signal contacts aligned with each other above and below across the insulator plate. The insulator plate has a thickness so determined that when a pair of terminal of each of the paired cables are exposed at their one ends by removing their insulating coverings and then fitted on the insulator plate without changing the initial spacing between the pair of terminals in a manner embracing the insulator plate by the pair of terminals on the upper and lower surfaces, the pair of terminals are electrically connected to a pair of the signal contacts on the upper and lower surfaces of the insulator plate. With this arrangement, good impedance characteristics at the one ends of the paired cables can be maintained.

Abstract: A C-shaped compliant contact is composed of a connection portion to be connected to an electric cable or the like, a press-fitting portion to be press-fitted in a through-hole of the printed circuit board, and a contact portion to contact a contact of a mating connector. The press-fitting portion has an inner periphery forming a U-shaped groove in section and an outer periphery forming at least one arc portion. The circle inscribing the inner periphery of the U-shaped groove is in an eccentric relation to the arc portion of the outer periphery. The thickness of the arc portion in cross-section progressively decreasing on proceeding toward the open end of the U-shaped groove to make longer the arc portion contacting the through-hole of the printed circuit board. The U-shaped groove is formed with a ramp surface located inside the inner periphery near to the connection portion, connected to the bottom of the U-shaped groove and inclined to make shallower the U-shaped groove, thereby preventing the connection portion of the contact from being bent when it is being press-fitted into the through-hole of the printed circuit board.

Abstract: A connector includes a required number of contacts, an electrical insulation housing and a metallic shell. A tab is formed in the connector. A pressure receiving portion of the tab is pushed by a pushing portion of the shell to move the pressure receiving portion toward a mounting face of a substrate for applying a force in the insertion of FPC but not applying a force to the tab in the detaching thereof, whereby an engaging portion of the tab is moved in a direction opposing to the mounting face of the substrate to unfasten the engaging portion from an locking portion of the FPC.
