In such a configuration, in a state in which the two electrical connectors are in correspondence with each other, a comparatively large gap is easily generated between the shield wall provided in the electrical connector on one side and the platen of cabling on which the corresponding associated part (plug connector or equivalent) is mounted, and it is conceivable that sufficient electromagnetic shielding function can not be obtained for the overall electrical connector device. Therefore, further improvement of the electromagnetic shielding characteristics (electromagnetic interference characteristics) with respect to high frequency transmission signals is desired.
