Power connector providing improved performance

An electrical connector for mounting on a printed circuit board, comprising:

• a dielectric shell defining a cavity and an opening in a front wall thereof, the opening communicating with the cavity;
• a conductive main body received in the cavity and defining a passage in alignment with the opening, a row of passageways being defined in the main body at at least one lateral side of the passage, and a channel being defined in a side surface of the main body at the at least one lateral side of the passage, the channel being in communication with the row of passageways;
• a conductive pin accommodated in the passage and having a front member protruding through the opening of the shell;
• and
• a row of terminals being received in the passageways, each of the terminals providing a curved contacting portion projecting from a corresponding passageway into a corresponding channel toward the passage for abutting against the main body.

An electrical connector comprising:

• a dielectric shell defining a cavity;
• a conductive main body received within said cavity;
• a plurality of passageways defined in the main body in a vertical direction;
• a channel extending horizontally and intersecting the passageways;
• a slit extending upwardly from a bottom face of the main body in communication with the passageways;
• a plurality of terminals disposed in the main body, intermediate portions of said terminals being connected together to be received within the slit, each of said terminals including a mating portion above the corresponding intermediate portion, said mating portion received within the corresponding passageway with a stem received within the channel;
• wherein
• said stem is curvedly deformed in the channel only after the terminal has been completely received in the passageway so as to prevent withdrawal of the terminal from the passageway.

• a conductive main body received in the cavity and defining a passage in alignment with the opening, a row of passageways being defined in the main body at at least one lateral side of the passage, and a channel being defined in a side surface of the main body at the at least one lateral side of the passage, each of the passageways including a first passageway and a second passageway and the channel communicating the first passageways with the second passageways;
• a conductive pin accommodated in the passage and having a front member protruding through the opening of the shell;
• and
• a row of terminals being received in the passageways, each of the terminals having a mating portion, a retention portion, and a soldering portion for soldering to the printed circuit board, the mating portion comprising a lower portion received in a corresponding second passageway, an upper portion received in a corresponding first passageway, and a contacting portion connecting the lower portion with the upper portion and projecting from a corresponding passageway into a corresponding channel, wherein the main body defines a slit extending upward from a bottom surface of the main body at the at least one lateral side of the passage, and the slit communicates with the second passageways of the row of passageways at the at least one lateral side of the passage, the retention portions of the row of terminals being interconnected in a plane and being received in the slit, the retention portions of the row of terminals forming a plurality of projections, the terminals being assembled into the main body such that the projections abut against a side of the slit away from the passage, thereby forcing the terminals to tightly abut against inner sides of the corresponding passageways and forcing the contacting portions to tightly abut against an inner side of the channel.
