  • Patent number: 11735877
    Abstract: An electrical receptacle connector is enclosed by an outer shell. The outer shell includes a rear covering plate, side plates, and top plates. Two turned portions are at two sides of the rear covering plate. The side plates outwardly extend from the turned portions, respectively. Each of the top plates is bent from a top portion of the corresponding side plate and extends away from the corresponding side plate. The rear covering plate and the side plates are integrally formed as a one-piece member. Hence, the steps of manufacturing process for the connector can be reduced, the production of defective products can be reduced, and the structural strength of the connector can be improved. Moreover, numbers of holes or cracks between the rear covering plate and each of the side plates can be reduced, thereby reducing the EMI issue.
