Abstract:
1. A stacked electrical connector comprising: a first insulator having a vertical rear plate and a first connector extending forwardly from a top side of the rear plate in order to form a receiving opening restricted by the rear plate and a bottom wall of the first connector, the bottom wall having a first retention member; and a second insulator having a second connector located under the first connector, the second insulator comprising a top wall and a pair of side walls, a second retention member being formed on the top wall for mating with the first retention member, each side wall being layer shaped and comprising an outer layer and an inner layer which is contracted compared with the out layer along a transverse direction; wherein the second insulator is assembled to the first insulator along a front-to-rear direction perpendicular to the transverse direction with the inner layers received in the receiving opening; wherein the first retention member is a protrusion or a dovetail shaped recess, and the second retention member is a rest of the protrusion or the dovetail shaped recess under a condition that the protrusion has an upper narrow section and a lower wide section so that, when the protrusion is received in the dovetail shaped recess, a movement between the protrusion and the dovetail shaped recess along a vertical direction can be prevented; wherein the first insulator comprises a pair of side portions extending forwardly from the rear plate with the receiving opening located between the pair of side portions, each side wall of the second insulator comprising a fracture wall separating the outer and the inner layers under a condition that each side portion of the first insulator has a front engaging wall abutting against the fracture wall for positioning purpose; and wherein both the fracture wall and the front engaging wall are oblique, the out layer of the second insulator is coplanar with the corresponding side portion of the first insulator from an exterior view.
