Electrical connector having metallic outer cover equipped with transversely linked mounting ears and sealing element secured upon front end region

1. An electrical connector comprising:

an insulative housing having a base portion and a tongue portion;

a plurality of contacts affixed to the insulative housing and exposed to the tongue portion;

an outer cover enclosing the insulative housing, the outer cover having a plurality of peripheral grooves open at a front face thereof; and

a sealing element having a plurality of protrusions secured to the plurality of grooves, wherein said contacts are assembled within the insulative housing to commonly form a contact module enclosed in the outer cover, wherein said outer cover is metallic, wherein said outer cover includes a tubular main portion and a pair of side arms unitarily extending outwardly from the tubular main portion in a transverse direction, wherein each of said side arms including a mounting ear linked to the tubular main portion via a connecting portion in the transverse direction.

2. The electrical connector as claimed in claim 1 , wherein the groove has a trapezoidal shape.

3. An electrical connector comprising:

a contact module including a plurality of contacts retained in an insulative housing, said housing including a base and a tongue portion extending forwardly from the base along a front-to-back direction;

a metallic outer cover enclosing the contact module and including an elliptic tubular main portion and a pair of side arms unitarily extending from two opposite sides of the main portion in a transverse direction perpendicular to the front-to-back direction, the elliptic tubular main portion defining a mating cavity in which the tongue portion extends forwardly along the front-to-back direction and further out of the mating cavity; and

a front sealing element surrounding a front end region of the outer cover; wherein each of said side arms is aligned with the mating cavity in the transverse direction, and includes a mounting ear having a hole therein and linked to the elliptic tubular main portion via a corresponding connecting portion, wherein said outer cover further includes a pair of mounting legs respectively located behind the pair of mounting ears, respectively, in the front-to-back direction, wherein said connecting portion is tapered in a vertical direction perpendicular to both the front-to-back direction and the transverse direction, wherein said front sealing element includes a plurality of protrusions respectively snugly engaged within corresponding grooves formed in the front end region.

4. The electrical connector as claimed in claim 3 , wherein a cross-section of the groove is trapezoidal.

5. An electrical connector assembly comprising:

a printed circuit board;

an electrical connector including:

a pair of mounting legs secured to the printed circuit board;

a contact module including a plurality of contacts retained in an insulative housing, said housing including a base and a tongue portion extending forwardly from the base along a front-to-back direction; and

a metallic outer cover enclosing the contact module and including an elliptic tubular main portion and a pair of side arms unitarily extending from two opposite sides of the main portion in a transverse direction perpendicular to the front-to-back direction, the elliptic tubular main portion defining a mating cavity in which the tongue portion extends forwardly along the front-to-back direction and further out of the mating cavity; wherein

each of said side arms is located in front of the corresponding mounting legs in the front-to-back direction and aligned with the mating cavity in the transverse direction, and includes a mounting ear having a hole therein and linked to the elliptic tubular main portion via a corresponding connecting portion, wherein the mounting legs are formed by the metallic outer cover, wherein the contacts are arranged in two rows, and the mounting legs are formed by a pair of metal pieces sandwiched between the said two rows of contacts in a vertical direction perpendicular to both the front-to-back direction and the transverse direction, further including a sealing element around a front end region of the outer cover, wherein said sealing element includes a plurality of protrusions snugly received within corresponding grooves formed in the front end region of the outer cover.

6. The electrical connector assembly as claimed in claim 5 , wherein a cross-section of the groove is trapezoidal.
