Electrical connector

An electrical connector adapted to be mounted to an electrical device having a conductive casing and in electrical engagement with a circuit board inside the casing, comprising:

• an insulative housing having a body portion and a projection extending from the body portion, the housing defining an interior space therein for accommodating a plurality of conductive pins adapted to be electrically engageable with the circuit board;
• a conductive shielding shell fitting over the projection of the housing and adapted to engage with the conductive casing of the electrical device;
• and
• at least one conductive board lock member fixed to the housing and having a U-shaped portion from which an extension portion horizontally extends for being positioned on the circuit board, and an engaging section vertically downwardly extending from the extension portion and being parallel to and offset from the U-shaped portion to be adapted to mechanically and electrically engage with the circuit board for retaining the connector on the circuit board, the board lock member comprising a fastener made from a conductive material and having an expanded end portion received in the U-shaped portion and engaging therewith for establishing an electrical connection between the shielding shell and the board lock member so as to maintain a grounding connection between the circuit board, the connector shell and the casing, wherein said fastener extends through and secures the shielding shell, the housing and the board lock member together.
