Abstract

An electrical connector (100) includes an insulative housing (1), a number of contact terminals (2), a metal plate (3), and a metallic shell (4) enclosing the insulative housing (1). The terminals and the metal plate (3) are retained in the insulative housing (1). The insulative housing (1) includes a base portion (11) and a tongue portion (12) extending forward from the base portion (11). The contact terminal includes a contacting portion (21), a tail (22), and a connecting portion (23) connecting the contacting portion (21) and the tail (22). The tails (22) are positioned out of the insulative housing (1). The metal plate (3) has a number of positioning end portions (33). The positioning end portions (33) are soldered on a printed circuit board for grounding. The electrical connector (100) has improved electromagnetic interference effect.

Claims

1. An electrical connector comprising:

an insulative housing having a base portion and a tongue portion extending forwardly from the base portion;

a plurality of contact terminals disposed in the insulative housing, each contact terminal including a flat contact portion for connecting with a mating connector, a tail extending out of a back wall of the base portion for soldering with a printed circuit board, and a connecting portion connecting the flat contact portion and the tail;

a metallic shell comprising a top wall, a bottom wall, and two side walls connecting with the top wall and the bottom wall for cooperatively defining a receiving room in which the mating connector is inserted; and

a metal plate retained in the tongue portion of the insulating housing, the metal plate comprising at least one positioning end portion, the at least one positioning end portion extending out of the insulative housing for soldering with the printed circuit board, wherein the at least one positioning end portion is substantially coplanar with the tails of the contact terminals, wherein the metal plate comprises a plan main portion covering the tongue portion, and the plan main portion has a pair of side parts extending from two sides thereof and a front part extending from a front end thereof, the pair of side parts and the front part respectively covering the two side surfaces and the front surface of the tongue portion of the insulative housing, wherein the plan main portion defines a gap between each corner formed by each side part and said front part.

2. The electrical connector as claimed in claim 1, wherein the plan main portion comprises a rib extending downwardly from an upper middle surface thereof perpendicular to the side parts.

3. The electrical connector as claimed in claim 2, wherein the tongue portion comprises a plurality of location holes, the metal plate has corresponding through holes, and the location holes extends beyond the plan main portion through the corresponding through holes.

4. The electrical connector as claimed in claim 3, wherein the rib is located between the through holes.

5. The electrical connector as claimed in claim 3, wherein the rib has a length smaller than that of the though hole.

6. The electrical connector as claimed in claim 1, wherein the contact portion is wider than said tail, and a space between every two adjacent contact portions is narrower than that between every two adjacent tails.

7. The electrical connector as claimed in claim 6, wherein the at least one positioning end portion is wider than the contact portion.

8. An electrical connector comprising:

an insulative housing defining a body portion and a mating tongue extending forwardly from the body portion, said mating tongue defining opposite first and second faces;

a plurality of contacts disposed on the housing, each of said contacts defining a contacting section exposed upon the first face, and a tail section exposed rearwardly outside of the housing;

a metallic plate integrally formed with the housing with a planar cover shielding the first face, and at least one solder pad exposed outside of the housing around the tail sections of the contacts; and

a first metallic shell assembled to the housing to define a mating port in which said mating tongue extends forwardly, wherein said metallic plate is associated with the housing via an insert molding process, further including a second metallic shell assembled upon the first metallic shell, wherein said second metallic shell defines a U-shaped configuration so as to be assembled to the first metallic shell with an opening around the solder pad, wherein said second metallic shell is configured to be assembled to the first metallic shell in a vertical direction.

9. The electrical connector as claimed in claim 8, wherein said metallic plate defines two opposite solder pads by two sides of the tail sections of the contacts in a transverse direction.
