Low-profiled electrical connector with improved terminals

An electrical connector for being mounted on a printed circuit board (PCB), comprising:

• an insulative housing having a base portion, a mating portion extending forwardly from a front face of the base portion, a mounting portion extending rearwardly from a rear face of the base portion, a plurality of passageways defined in the mating portion, a space defined between the rear face of the base portion and an upper face of the mounting portion for receiving the PCB therein;
• a terminal module having an insulation mounted to the base portion of the housing and a plurality of terminals molding with the insulation, each terminal having a middle portion molded with the insulation, a mating portion extending forwardly from the middle portion into a corresponding passageway, a leg portion extending rearwardly from the middle portion adapted to extend through the PCB, the leg portion having a U-shaped configuration;
• wherein the leg portion has an extending portion extending downwardly from the middle portion, a connecting portion extending rearwardly from the extending portion, and a tail portion extending upwardly from the connecting portion adapted to be soldered to the PCB;
• wherein the mounting portion has a pair of arms and a tongue portion connected to the pair of arms;
• wherein a spacer is mounted between the arms and having a plurality of through holes therein, said tail portions of the legs of the terminals extending through the through holes;
• wherein a first receiving space is defined in the base portion and receives the insulation of the terminal module therein;
• wherein a second receiving device is defined in the base portion beside the first receiving space;
• wherein the terminals of the terminal module are used for transmitting digital signal and the connector further comprises a second terminal module received into the second receiving space, the second terminal module having terminals for transmitting analogous signal;
• wherein a plurality of barbs is formed on a pair of sides of the connecting portion, a plurality of blocks is formed on the tongue portion, the barbs engaging the blocks;
• wherein the mating portion of terminal has a fork shape;
• wherein a grounding shield including a plate, a shroud forwardly projecting from the plate and surrounding the mating portion of the housing, a plurality of claws formed at opposite lateral ends of the plate and a pair of positioning hole defined in the opposite later ends of the plate;
• wherein the rear face of the base portion defines a pair of holes corresponding the positioning holes and a pair of depressed portions above and below a corresponding hole;
• wherein a pair of nuts fitted in the holes of the base portion adapted for threadedly engaging with screws of a complementary connector;
• wherein a grounding plate (grounding element) is inserted in the second terminal module;
• wherein a pair of soldering tabs each comprising at least a finger portion for soldering to the PCB, a pair of securing portion fitted in corresponding depressed portions of the base portion of the housing, and a retention portion securely fitted into the base portion of the housing;
• wherein the base portion of the housing has an intermediate wall defining a plurality of grooves facing the first receiving space and receiving a lateral edge of insulation of the terminal module;
• wherein each of the arms forms a post at a top surface thereof for fitting into the PCB.
