Electric connector
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.
1. An electric connector comprising:
a first connector and a second connector each of which is provided with a plurality of conductive terminals arranged at suitable pitch intervals in a multipolar manner along a longitudinal widthwise direction of a slender flat plate-like insulating housing and a conductive shell covering an outer surface of the insulating housing,
wherein the first and second connectors are a receptacle connector mounted on a printed circuit board and a plug connector fitted in the receptacle connector, respectively, which are fitted to each other in a direction approximately perpendicular to a direction of the multipolar arrangement in such a manner that the plug connector is plugged and fitted in a direction approximately perpendicular to a plane of the printed circuit board mounted with the receptacle connector so that the conductive terminals of the receptacle and plug connectors and the conductive shells are brought in contact with each other, respectively, to form a terminal connecting portion CS and a shell connecting portion SS, and
wherein the shell connecting portion SS is disposed opposite to the terminal connecting portion CS through the insulating housing of the plug connector in a direction perpendicular to a fitting direction of the receptacle and plug connectors.
