Abstract
Disclosed is an anti-deformation structure of a connector. The connector comprises an upper plastic base, a lower plastic base, upper-row terminals, lower-row terminals, wherein the upper-row terminals and the lower-row terminals are fastened with each other. Besides, the lower-row terminals are fixedly arranged on the lower plastic base, a plastic protective cover used for pressing the upper-row terminals and the lower-row terminals is arranged at the fastened joint of the upper-row terminals and the lower-row terminals, two ends of the plastic protective cover are respectively fastened with the lower plastic base through a first fastener structure, and the first fastener structures are fastened with the lower plastic base outside in. After the connector is assembled with a PCB (printed circuit board) in an inverted manner, the plastic protective cover can deform upwards only as the first fastener structures on two sides of the plastic protective cover are fastened with the lower plastic base outside in during SMT (surface mounted technology) process, and then deformation of the plastic protective cover can be suppressed by the blockage of the lower plastic base, so that fine coplanarity of the plastic protective cover is guaranteed, insufficient soldering due to deformation of the plastic protective cover is avoided and performance of the connector is guaranteed further.
