Abstract

A receptacle connector includes a first housing, a second housing, a number of first contacts and second contacts, a metallic plate sandwiched between the first housing and the second housing, and a shielding shell. The first housing has a first base and a first tongue portion. The first tongue portion has a connection portion close to the first base and a first stepping portion in a lower surface. The second housing has a second tongue portion. The second tongue portion has a second stepping portion in an upper surface. Each first contact has a first affixed portion. The metallic plate has a connecting section inclining with the connection portion and the first affixed portion in a same direction and an opening receiving the first stepping portion and the second stepping portion. The first stepping portion and the second stepping portion contacts with each other through the opening.

Claims

1. A receptacle connector comprising:

a first insulative housing having a first base portion and a first tongue portion extending forwardly from the first base portion, the first tongue portion having a connection portion close to the base portion with a first stepping portion in a lower surface thereof;

a second insulative housing having a second base portion and a second tongue portion extending forwardly from the second base portion, the second tongue portion having a second stepping portion in an upper surface thereof;

a plurality of first contacts carried by the first insulative housing, each first contact having a first contacting portion, a first affixed portion, and a first soldering portion;

a plurality of second contacts carried by the second insulative housing;

a metallic shielding plate sandwiched between the first insulative housing and the second insulative housing, the metallic shielding plate having a connecting section inclining with the connection portion and the first affixed portion in a same direction and an opening receiving the first stepping portion and the second stepping portion, the first stepping portion and the second stepping portion contacting with each other through the opening; and

a shielding shell attached to the first and second insulative housings.

2. The receptacle connector as claimed in claim 1, wherein said first stepping portion and the second stepping portion respectively have a step surface, and the step surface of the first stepping portion is located at a lower surface of the first tongue portion and resisted against by the step surface of the second stepping portion located at an upper surface of the second tongue portion.

3. The receptacle connector as claimed in claim 2, wherein said first stepping portion and the second stepping portion shape in right angles and respectively have a pair of flat surfaces, the step surface is located at the flat surface, and the flat surface has a vertical surface perpendicular to the step surface.

4. The receptacle connector as claimed in claim 1, wherein said first affixed portions of the first contacts are received in a lower surface of the connection portion, and the first stepping portion is located at a lower surface of the connection portion.

5. The receptacle connector as claimed in claim 1, wherein said first stepping portion protrudes downwardly to the opening and the second stepping portion protrudes upwardly to the opening.

6. The receptacle connector as claimed in claim 5, wherein said first stepping portion has a pair of ribs located at two sides thereof, the second stepping portion has a pair of ribs located at two sides thereof, and first stepping portion and the second stepping portion have an aperture therebetween to flow glue.

7. An electrical connector comprising:

a first insulative housing having a front first tongue portion and a rear first base portion in a front-to-back direction, said first base portion being higher than the first tongue portion in a vertical direction perpendicular to said front-to-back direction, and connected with each other via an obliquely extending first connection portion therebetween in said front-to-back direction, a first step structure formed on the first connection portion;

a second insulative housing having a front second tongue portion and a rear second base portion in the front-to-back direction, said second base portion being higher than the second tongue portion connected with each other via another obliquely extending second connection portion therebetween in the front-to-back direction, a second step structure formed on the first connection portion;

a metallic grounding plate sandwiched between said first insulative housing and said second insulative housing in and including a supporting section and a panel section with an obliquely extending connection section therebetween in the front-to-back direction, wherein said supporting section is sandwiched between the first tongue portion and the second tongue portion in the vertical direction to form a sub-assembly, said panel is sandwiched between the first base portion and the second base portion in the vertical direction, and said connection section is sandwiched between the first connection portion and the second connection portion in an oblique direction;

wherein said grounding plate forms an opening through which the first step structure and the second step structure are coupled with each other intimately to resist imposed force along the vertical direction.

8. The electrical connector as claimed in claim 7, wherein an escaping space is formed between the first connection portion and the second connection portion beside the coupled first step structure and second step structure so as to receive therein redundant material of a third insulative housing which is overmolded upon said sub-assembly.

9. The electrical connector as claimed in claim 7, further including a plurality of first contacts insert-molded within the first insulative housing, and a plurality of second contacts insert-molded within the second insulative housing.

10. The electrical connector as claimed in claim 7, wherein each of said first base portion and said second base portion further include a guiding hole communicating with each other in the vertical direction, and at least one of said guiding holes communicates with an exterior for injection of glue to form a glue wall for waterproof.

11. The electrical connector as claimed in claim 10, wherein a third insulative housing is overmolded upon the sub-assembly to form a housing assembly, and a metallic shell encloses the housing assembly, and said glue wall fills space behind the third insulative housing and the first connection portion and the second connection portion in said shell.

12. The electrical connector as claimed in claim 11, wherein the first base portion and the second base portion extend through said glue wall rearwardly.

13. The electrical connector as claimed in claim 12, wherein said grounding plate extends through said glue wall rearwardly.

14. The electrical connector as claimed in claim 7, wherein said first step structure includes at least one horizontal first plane and said second step structure includes at least one horizontal second plane abutting against the first plane in the vertical direction.
