Complex electrical connector

An electrical connector assembly comprising:

• a first connector comprising a first connector interface and a second connector interface, the first connector interface being in a tongue shape and the second connector interface being in a frame shape;
• a second connector mating with the first connector, the second connector comprising a third connector interface and a fourth connector interface which are arranged side by side along a longitudinal direction thereof and mating with the first and second interfaces respectively;
• the third connector interface defining a mating slot surrounded by sidewalls, the fourth connector interface defining two tongue portions with a plurality of contacts arranged on the tongue portions;
• wherein the tongue portions of the fourth connector interface are arranged side by side and spaced away from each other along the longitudinal direction, one tongue portion joined with an inner face of one end wall, of which at an outer face a guiding post is defined.

An electrical connector assembly comprising:

• a first connector including:
• a first insulative housing defining a longitudinal direction, a transverse direction and a mating direction perpendicular to one another;
• said first housing defining a forwardly extending first mating tongue essentially in compliance with a first mating interface, and a pair of forwardly extending second mating tongues essentially in compliance with a second mating interface, said first mating tongue and said pair of second mating tongues being side by side arranged with each other in said longitudinal direction, a first small frame circumferentially enclosing the pair of second mating tongues except on an end side of said pair of second mating tongues in said longitudinal direction, and a first large frame enclosing both the first mating tongue and said pair of second mating tongues except on a longitudinal side of said first mating tongue and said pair of mating tongues;
• and
• a second connector mated with said first connector and including:
• a second insulative housing a defining a slot essentially in compliance with a third mating interface under condition that the third mating interface matches the first mating interface, and the first mating tongue is electrically and mechanically received in the slot;
• and a pair of mating plates essentially in compliance with a fourth mating interface under condition that the fourth mating interface matches the second mating interface, and the pair of mating plates are received in the small frame to electrically and mechanically connect the corresponding pair of second mating tongues;
• wherein
• the second insulative housing defining a second large frame enclosing both said slot and said pair of mating plates except a portion of a longitudinal side, which is aligned with said pair of mating plates in the transverse direction.
