Abstract

An electrical connector (1) includes an insulative housing (2), a number of signal and power contacts (3, 4), a first and a second shell-halves (51, 52), and a grounding strip (6). The grounding strip includes a bar portion (60), a plurality of claws (61) and a pair of contacting portions (62). The insulative housing includes a shroud wall formed by a pair of longitudinal walls (22, 23) and defining a receiving cavity (200), and a tongue portion (21) extending into the receiving cavity. The tongue portion defines a plurality of passages (211, 212) to receive the contacts, a receiving groove (210) to receive the bar portion and a plurality of engaging grooves (213) located beside the receiving groove symmetrically and engagingly receiving the claws. Each shell-half includes a plate portion (50) enclosing the longitudinal wall and a side portion (511) vertically extending from the plate portion and enclosing the lateral wall. The contacting portions of the grounding strip electrically connect with the side portions of the shielding shell, respectively.

Claims

1. An electrical connector, comprising:

an insulative housing comprising a shroud wall defining a receiving cavity and a tongue portion extending into the receiving cavity, the shroud wall comprising a pair of longitudinal walls and a pair of lateral walls, the tongue portion defining a plurality of passages in opposite sides thereof, a receiving groove in a top surface thereof and a plurality of engaging grooves located beside the receiving groove symmetrically;

a plurality of terminals respectively received in the passages of said tongue portion;

a conductive shielding shell enclosing the insulative housing and comprising a first shell-half and a second shell-half, each of the first and the second shell-halves comprising a plate portion endosing the longitudinal wall and a side portion vertically extending from the plate portion and enclosing the lateral wall; and

a grounding strip comprising a bar portion received in said receiving groove, a plurality of claws respectively engagingly received in said engaging grooves and a pair of contacting portions formed at opposite ends of the bar portion and electrically contacting with the side portions of the first and the second shell-halves for being grounded;

wherein the terminals comprise a plurality of signal contacts and a plurality of power contacts,

wherein the side portion of the shielding shell forms a connection portion, and wherein the insulative housing forms a pair of guiding posts extending upwardly from each lateral wall, the pair of guiding posts forming a gap therebetween to receive the connection portion of the;

wherein the plate portion of each of the first and the second shell-halves forms a plurality of retaining sheets, and wherein the insulative housing forms a plurality of tubers, the retaining sheets being respectively received between every two adjacent tubers;

wherein each retaining sheet is formed with a soldering pad adapted for being soldered to a printed circuit board;

wherein each of the first and the second shell-halves forms a plurality of latches, and wherein the insulative housing forms a plurality of extrusions on opposite longitudinal walls respectively engaging with said latches.

2. The electrical connector as claimed in claim 1, wherein the insulative housing forms a pair of flanges integrally extending from the lateral walls, each flange and the corresponding lateral wall together forming a pair of channels, and wherein each side portion of the first and the second shell-halves forms a leg portion received in the channel.

3. An electrical connector assembly comprising:

an electrical connector including;

an elongated insulative housing extending along a lengthwise direction and defining a mating face and a mounted face opposite to said mating face in an oblique manner so as to form a long side and a short side along a transverse direction perpendicular to said lengthwise direction;

a plurality of passageways extending in said housing in a vertical direction perpendicular to said mating face and to both said lengthwise and transverse directions;

a metallic piece disposed in the housing, said metallic piece stamped from a metal sheet and extending in a transverse plane perpendicular to said lengthwise direction,

a printed circuit board obliquely positioned under the housing and in a parallel relation with the mounting face;

a plurality of through holes perpendicularly extending through the printed circuit board and with a perpendicular relation with regard to the mounting face;

wherein said metallic piece includes a soldering tip which is coplanar with a main body of the metallic piece without bending, and said soldering tip extends downwardly perpendicular to said mounting face and through the corresponding through holes in an alignment manner;

further including another metallic niece disposed in the housing, said another metallic piece extends in a lengthwise plane perpendicular to said transverse direction, wherein said another metallic piece includes a solder portion which is coplanar with a main body of said another metallic piece without bending, and said solder portion extends downwardly perpendicular to the mating face while oblique to the mounting face, and wherein said solder portion extends through the corresponding through hole obliquely;

further including a positioning post integrally downwardly extending from the mounting face of the housing and through the corresponding through hole, wherein said positioning post defines a vertical side perpendicular to the mating face while oblique to the corresponding through hole, and an oblique side perpendicular to the mounting face and aligned with the through hole.
