  • Electrical connector both preventing scrapping to an insulative body and reducing antenna interference
    Patent number: 9293869
    Abstract: An electrical connector (100) includes an insulative body (2), a number of contacts (1), and a metal shell (5). The insulative body includes an upper wall (21), a lower wall (22) opposite to the upper wall, a pair of sidewalls (23), and a rear wall (24) connecting between the upper wall, the lower wall, and the sidewalls for cooperatively defining a receiving space (20). The insulative body has a mating tongue (25) extending forwardly from the rear wall into the receiving space. The contacts are retained in the mating tongue and partly exposed in the receiving space. The metal shell has a pair of arc portions engaging with a mating plug connector. The metal shell is positioned on the upper wall for reducing interference between the metal shell and an antenna mounted on a printed circuit board.
