ELECTRICAL CONNECTOR WITH ADDITIONAL SHIELDING
First Claim
1. An electrical connector comprising:
- a contact module including a plurality contacts retained in an insulator;
an insulative elongated housing, in which the contact module is received, extending along a longitudinal direction to define opposite top and bottom surfaces in a vertical direction perpendicular to the longitudinal direction, a pair of side surfaces along the longitudinal direction, and opposite front and rear surfaces in a front-to-back direction perpendicular to both the longitudinal direction and the vertical direction, said housing further defining a horizontal rear middle surface between the top surface and the bottom surface in the vertical direction and a vertical rearward surface roughly joined with the middle surface and rearwardly facing in the front-to-back direction;
a metallic shielding unit including;
a one piece primary shell being of a frame structure and forming a top wall covering the top surface, a lower wall covering a bottom surface, a pair of side walls covering the pair of side surfaces; and
a one piece Z-shaped secondary shell forming a vertical first section covering the rearward surface, a horizontal second section extending from an upper edge of the first section to cover the middle surface, and further an addition section extending from a lower edge of the first section to be located below and welded to the lower wall so as to prevent any EMI (Electro-Magnetic Interference) leakage, in the front-to-back direction, between the primary shell and the secondary shell around a corner between the bottom surface and the rearward surface of the housing.

Abstract
A electrical connector includes an insulative elongated housing and first and second metallic shells covering the housing. The housing includes a top surface, a bottom surface, two sides surfaces and a middle surface between the top surface and the bottom surface so as to form a step structure thereof. The primary shell covers the top surface, the bottom surface and two side surfaces, and the secondary shell covers the middle surface and the rear surface which is roughly joined with the middle surface, and further the primary shell on the bottom surface in an overlapped manner so as to avoid any electrical leaking along the front-to-back direction between the primary shell and the secondary shell.
