摘要： Occurrence of defective electrical connection caused by dust that has entered the interior through a corresponding insertion hole can be prevented well by a simple configuration. A through hole facing a corresponding insertion hole is formed to penetrate through a movable contact attached to an insulating housing, and two corresponding connector contact pieces are disposed respectively in both sides sandwiching the through hole. Thus, the dust that has entered the interior through the corresponding insertion hole opened when a corresponding connector is not mated is configured to be discharged through the through hole without accumulating the dust on the movable contact to reduce the risk that the electrical conductivity between the movable contact and the fixed contact may be disturbed by the dust.

摘要： An electrical coaxial connector comprising a body made of insulator to be put on a circuit board, a signal-joining contacting conductor held by the body, and a grounding contacting conductor formed into a cylindrical shape and held also by the body for surrounding the signal-joining contacting conductor on the circuit board, wherein the grounding contacting conductor has an arm portion extending toward the circuit board from one of ring-shaped ends of the grounding contacting conductor, which is more distant from the circuit board than the other, a grounding terminal portion is formed at an end of the arm portion to be soldered to a ground-potential terminal provided on the circuit board, and each of the grounding contacting conductor and the arm portion is resilient.

摘要： Such a configuration is achieved that shell connecting portion which is a contact portion of conductive shells of first and second connectors fitted to each other in a direction approximately perpendicular to multipolar arrangement is disposed opposite to a terminal connecting portion which is a contact portion of conductive terminals, so that contact pressure at the shell connecting portion is caused to function on the terminal connecting portion to improve electric contact performance of the terminal connecting portion, and the conductive shells are disposed approximately along the conductive terminals to improve a function for shielding electromagnetic waves generated based upon electric signals flowing in the conductive terminals. By adopting such a configuration, even if an electric connector is lowered in height and downsized, contact reliability of the conductive terminals is maintained well, so that improvement of properties of electromagnetic interference (EMI) and electrostatic discharge (ESD) can be achieved.

摘要： A compatible CF card adapter (1) permits a thick or thin CF card (7) to be nested therewith. The CF card adapter includes pin contacts (4a) projecting from a housing (4b) for mating with the female contacts of the CF card. The CF card adapter has a slidable contact cover (4f) spring-biased to enclose the pin contacts (4a). The contact cover (4f) is responsive to insertion of the CF card for yieldingly withdrawing to expose the pin contacts (4a) behind, thereby permitting the pin contacts (4a) to be mated with the receptacle terminals of the CF card.
