Abstract: A plug connector includes a signal contact conductor to which an internal conductor of a coaxial cable is connected, a ground contact conductor to which an external conductor of the coaxial cable is connected, and an insulating housing that insulates the signal contact conductor from the ground contact conductor. The insulating housing includes an insulating main body in which the signal contact conductor is held and a protrusion that protrudes from a peripheral surface of the insulating main body in a radially outward direction of the insulating main body. The protrusion includes a base portion on which an insulator and the external conductor of the coaxial cable are placed and a pair of walls that are erected on the base portion and are disposed to interpose at least a tip of the external conductor therebetween.

Abstract: The retainability and electric connection reliability of a plate-shaped signal transmission medium can be increased by a simple configuration while the operability of an actuator is improved. Pre-pressing protruding portions which create a clicking sensation of a turning operation of the actuator are provided in part of a region in a longitudinal direction of the actuator so that the pressing force of the pre-pressing protruding portions with respect to the plate-shaped signal transmission medium is applied to the part in the longitudinal direction of the actuator, and the pressing force of the pre-pressing protruding portions with respect to the plate-shaped signal transmission medium is prevented from being largely increased even when the actuator is enlarged in the multipolar arrangement direction.

Abstract: Occurrence of unnecessary conduction or damage upon insertion of a plate-shaped signal transmission medium can be prevented by a simple configuration. The rigidity relation between a medium abutting portion and a coupling beam portion of a contact member is configured so that a contact point portion of the contact member is positioned in the interior of a contact housing portion in a stage before a plate-shaped signal transmission medium is sandwiched when the plate-shaped signal transmission medium is to be inserted to the interior of a medium insertion path along a medium guide surface of an insulating housing. By virtue of this, the contact point portion of the contact member is configured to be maintained in a state in which it is lowered below the medium guide surface upon insertion of the plate-shaped signal transmission medium so that the contact point portion of the contact member does not contact the plate-shaped signal transmission medium.

Abstract: An actuator includes a tabular partition that partitions, for each beam located at a position that allows the beam to abut the actuator, a through-hole into which one of a pair of beams located at the other-end side and at the position that allows the beam to abut the actuator is inserted to prevent the beam from abutting the actuator, and a wider-width part including a wider-width surface which is disposed at one end of the partition corresponding to an upstream side of a flow of resin flowed to mold the partition when the actuator is molded by the resin containing a filler, and which has a wider width than a width of the one end of the partition.

Abstract: Electromagnetic shielding about a part connected with a wiring substrate is easily and reliably carried out by a simple configuration without impairing productivity. A fixed shield plate provided at a shield shell member of an electric connector mounted on a wiring substrate is disposed to be opposed to a vicinity of a substrate connecting leg portion of a contact member. A movable shield plate covering a shell opening by a moving operation is provided. At least the substrate connecting leg portion of the contact member is covered from an outer side by fixed and movable shield plates, thereby well carrying out electromagnetic shielding (shielding) with respect to the part connected with the wiring substrate. Until the movable shield plate is subjected to the moving operation, the part connected with the wiring substrate can be checked well through the shell opening.

Abstract: The contact state of a signal transmission medium and contact members is enabled to be maintained well by a simple configuration. Medium pressing portions of an actuator, which is subjected to a moving operation so as to electrically connect contact portions of contact members, which are in a multipolar arrangement, and a signal transmission medium (FPC, FFC, or the like) to each other, are disposed at the same positions as the contact portions of the contact members in the direction of the multipolar arrangement. The medium pressing portions of the actuator at the positions directly opposed to the contact portions of the contact members are configured to press the signal transmission medium when the actuator is moved to a working position so that the contact pressures applied from the medium pressing portions of the actuator to the signal transmission medium are reliably applied to the contact portions of the contact members without being dispersed.
