Abstract
An electric connector comprises an insulating body and a plurality of terminals. The insulating body is provided with a plurality of longitudinally extending first retaining walls arrayed at intervals; a plurality of containing holes are distributed among the first retaining walls; the containing holes positioned between each two adjacent first retaining walls are arrayed longitudinally; each two adjacent containing holes positioned on the same longitudinal row are separated by a second retaining wall; each second retaining wall longitudinally projects forwards to form a reinforcing rib correspondingly entering one containing hole adjacent to the reinforcing rib; and each two adjacent first retaining walls are connected by one reinforcing rib so that the corresponding containing hole forms a deformation space positioned above the top surface of the reinforcing rib. As the reinforcing ribs are arranged by the aid of the idle spaces in the containing holes, the strength of the first retaining walls and the connecting strength of the second retaining walls are enhanced by the reinforcing ribs, high-density arrangement of the containing holes is benefited, and then the insulating body has better strength and is not easy to bend or deform.
Description
[technical field]
