Electrical connector with improved grounding performance

An electrical connector (100) comprising:

• an insulating body (6);
• a plurality of terminals retained in the insulating body (6);
• a shielding plate (5) embedded in the insulating body (6), the shielding plate (5) comprising a base portion (51) and at least one leg portion (52) extending vertically from at least one lateral side of the base portion (51) for electrically connecting with at least one grounding pad of a printed circuit board;
• an inner metal shell (8) enclosing the insulating body (6), the inner metal shell (8) comprising a larger-diameter circle portion (81) and a smaller-diameter circle portion (82) extending integrally and backwardly from the larger-diameter circle portion (81), the larger-diameter circle portion (81) surrounding the insulating body (6) to form an insertion space therebetween for receiving a mating connector;
• and
• an outer metal shell (9) assembled to the inner metal shell (8) with a lower surface of the outer metal shell (9) contacting an outer surface of the smaller-diameter circle portion (82), so as to establish grounding connection with the inner metal shell (8) and the shielding plate (5).

An electrical connector (100) comprising:

• a first lower insulating housing (1);
• a second upper insulating housing (2);
• a plurality of first conductive terminals (3) retained in the first lower insulating housing (1);
• a plurality of second conductive terminals (4) retained in the second upper insulating housing (2);
• an insulating body (6) molded over the first lower insulating housing (1) and the second upper insulating housing (2);
• a shielding plate (5) sandwiched between the first lower insulating housing (1) and the second upper insulating housing (2) and embedded in the insulating body (6), the shielding plate (5) comprising a base portion (51) and at least one leg portion (52) extending vertically from at least one lateral side of the base portion (51) for electrically connecting with at least one grounding pad of a printed circuit board;
• an inner metal shell (8) enclosing the insulating body (6), the inner metal shell (8) comprising a larger-diameter circle portion (81) and a smaller-diameter circle portion (82) extending integrally and backwardly from the larger-diameter circle portion (81), the larger-diameter circle portion (81) surrounding the insulating body (6) to form an insertion space therebetween for receiving a mating connector;
• an outer metal shell (9) assembled to the inner metal shell (8) with a lower surface of the outer metal shell (9) contacting an outer surface of the smaller-diameter circle portion (82), so as to establish grounding connection with the inner metal shell (8) and the shielding plate (5);
• and
• a waterproof plate (102) formed by glue injection into a slot which is formed by stacking the first insulating housing (1) and the second insulating housing (2).
