Abstract

An electrical connector including a contact module having an insulative housing with a plurality of contacts disposed therein and enclosed within a first metallic shell, and a second metallic shell attached to the first shell and located between the first shell and the printed circuit board so as to allow the raised type mating cavity which is formed by the first shell. The contact module includes a metallic shielding plate with an oblique section. A pair of Z-shaped fixing columns are located by two sides of the oblique section.

Claims

1. An electrical connector comprising:

a contact module including;

an insulative housing having a base and a tongue portion extending forwardly from the base in a front-to-back direction;

a plurality of contacts disposed in the housing;

a first metallic shell enclosing the contact module, said first metallic shell including opposite bottom and top faces and opposite side faces commonly forming a mating cavity in which the tongue portion extends; and

a second metallic shell attached to an underside of the bottom face;

wherein

said second metallic shell forms a pair of mounting legs on two opposite sides of a middle plate in a transverse direction perpendicular to the front-to-back direction, and each of said mounting legs includes a hole extending therethrough in a vertical direction perpendicular to both said front-to-back direction and the transverse direction;

wherein

each of said mounting legs lies in a horizontal plane and extends outwardly from the middle plate in the transverse direction;

wherein

the pair of mounting legs are coplanar with the middle plate so as to be adapted to be commonly seated upon a printed circuit board;

wherein the contact module includes an upper contact module and a lower contact module commonly sandwiching a metallic shielding plate therebetween in the vertical direction;

wherein the shielding plate includes a horizontal section embedded within the tongue portion, a pair of soldering legs exposed outside of the housing, and an oblique section between the horizontal section and the pair of soldering legs;

wherein the housing includes both an upper insulator of the upper contact module and a lower insulator of the lower contact module forming corresponding oblique portions to sandwich the oblique section of the shielding plate therebetween compliantly.

2. The electrical connector as claimed in claim 1, wherein said contacts include both a plurality of upper contacts in the upper insulator and a plurality of lower contacts in the lower contact module, said upper contacts and said lower contacts form corresponding oblique sections for complying with the oblique portions of the corresponding upper insulator and lower insulator.

3. The electrical connector as claimed in claim 1, wherein the first metallic shell forms an oblique section compliantly covering the oblique portion of the upper insulator and leave a receiving space above.

4. The electrical connector as claimed in claim 3, wherein said receiving space is aligned with the mating cavity in the front-to-back direction.

5. An electrical connector comprising:

a contact module including;

an insulative housing having a base and a tongue portion extending forwardly from the base in a front-to-back direction;

a plurality of contacts disposed in the housing;

a first metallic shell enclosing the contact module, said first metallic shell including opposite bottom and top faces and opposite side faces commonly forming a mating cavity in which the tongue portion extends; and

a second metallic shell attached to an underside of the bottom face;

wherein

said second metallic shell forms a pair of mounting legs on two opposite sides of a middle plate in a transverse direction perpendicular to the front-to-back direction, and each of said mounting legs includes a hole extending therethrough in a vertical direction perpendicular to both said front-to-back direction and the transverse direction;

wherein

each of said mounting legs lies in a horizontal plane and extends outwardly from the middle plate in the transverse direction;

wherein

the pair of mounting legs are coplanar with the middle plate so as to be adapted to be commonly seated upon a printed circuit board;

wherein the contact module includes an upper contact module and a lower contact module commonly sandwiching a metallic shielding plate therebetween in the vertical direction;

wherein the shielding plate includes a horizontal section embedded within the tongue portion, a pair of soldering legs exposed outside of the housing, and an oblique section between the horizontal section and the pair of soldering legs;

wherein a pair of Z-shaped side fixing columns are located by two opposite lateral sides of the oblique section of the shielding plate in the transverse direction to secure the upper contact module and the lower contact module together in the vertical direction.

6. An electrical connector comprising:

a contact module including;

an insulative housing having a base and a tongue portion extending forwardly from the base in a front-to-back direction;

a plurality of contacts disposed in the housing; and

a first metallic shell enclosing the contact module, said first metallic shell including opposite bottom and top faces and opposite side faces commonly forming a mating cavity in which the tongue portion extends;

wherein

each side face further includes a rearward extension defining a bending piece lying in a horizontal plane and abutting against the housing for preventing rearward movement of the housing relative to the shell, and a securing tab lying in another horizontal plane and located opposite to the bending piece in a vertical direction perpendicular to the front-to-back direction to be received in a recess in an underside of the housing for securing said first metallic shell to the housing;

wherein the shell further includes an oblique section on a rear side to form a receiving space in alignment with the mating cavity in the front-to-back direction;

further including a Z-shaped fixing column extending through the housing beside the oblique section in a transverse direction perpendicular to the front-to-back direction.
