Lower profile micro connector assembly

An electrical connector comprising:

• a front housing member having a mating surface and a joint surface at a front and a rear sides thereof and a tongue portion forwardly extending beyond the mating surface, said tongue portion having a front surface, an upper surface, a lower surface opposite the upper surface and a bottom portion adjacent to the lower surface, said front housing member defining a plurality of cavities from the joint surface thereof to the front surface of the tongue portion, each cavity comprising a first segment defined in the tongue portion and a second segment defined between the mating and joint surfaces, the first segment open to the upper surface and terminating at the bottom portion of the tongue portion;
• and
• a plurality of contacts each having a contact section adapted for electrically engaging with a mating connector and a first retention section adjacent to the contact section, the contact section and the first retention section being received in the first and second segments of a corresponding cavity of the front housing member, respectively, wherein the contact section is supported by the bottom portion and partially extends beyond the upper surface of the tongue portion;
• wherein the bottom portion of the tongue portion forms a plurality of blocks each protruding into the first segment of a corresponding cavity, each block bearing against the contact section of a corresponding contact;
• wherein the front housing member further comprises a pair of locking arms forwardly extending from opposite lateral ends of the tongue portion, each locking arm forming a hook at a free end thereof adapted for engageably locking to a mating connector;
• further comprising at least one shield shrouding the front housing member, wherein the front housing member respectively defines two recesses in opposite lateral walls thereof where lateral edges of the at least one shield are fixedly received;
• further comprising:
• a plurality of juxtaposed cables each having at least a conductive signal segment at a free end thereof, and a rear housing member having a plurality of passageways in alignment with the cavities of the front housing member;
• wherein each passageway retentively receives the conductive signal segment of a corresponding cable and a tail section of a corresponding contact, said tail section electrically connecting the corresponding conductive signal segment of the corresponding cable;
• and wherein the front housing member defines an opening in the joint surface thereof through which the rear housing member is inserted therein;
• wherein each of the contacts further includes a second retention section adjacent to the tail section which has an interference fit with the corresponding passageway for firmly retaining the contact therein;
• wherein each of the passageways further forms at least a protrusion therein for cooperation with said second retention section of the contact;
• wherein each of the passageways further forms a cavity at a bottom wall thereof for efficient reception of the tail section of the contact;
• wherein each of the juxtaposed cables includes a grounding segment insulated from and adjacent to the signal segment, and a grounding bar is perpendicularly and fixedly jointed with the grounding segment of each of the cables;
• wherein the rear housing member further forms a pair of spaced orientating walls adjacent to a rear surface of the rear housing member thereby forming an elongated slot for receiving the grounding bar joined with the cables therein;
• wherein the front housing member further includes a pair of opposite channels extending through the mating and joint surfaces thereof, each channel forming a swelling therein, and said rear housing member further includes a pair of latch portions extending forwardly from the rear housing member to be inserted in the channels of the front housing member, each latching portion forming a bow section for cooperation with the swelling thereby reinforcing the retention between the first and rear housing members.
