US Patent 7364464 Electrical docking connector

An electrical connector for engaging with a mating connector comprising an insulative housing, a plurality of contacts in the housing and a metallic shell covering the insulative housing. The metallic shell comprises a frame with at least one tab arranged at the front edge of the frame, so as to properly guide the mating connector to prevent contact misalignment or short-circuit during the mating process. The insulative housing comprises a base portion defining a pair of concavities so as to minimize size. A spacer is mounted at a rear end of the housing to prevent the contacts from moving rearward during mating.
