Electrical connector

An electrical connector, comprising:

• a first housing defining a receiving room therein;
• a second housing configured as an L shape and comprising a retaining section and a mating tongue extending forwardly from the retaining section perpendicularly, the mating tongue horizontally running through the receiving room of the first housing, a plurality of terminal grooves respectively defined on upper and lower sides of the mating tongue;
• and
• a plurality of contacts, divided into a first row contacts and a second row contacts, the second housing and the first row contacts being configured to have said first row contacts downwardly inserted into the terminal grooves on the upper side with first solder tails positioned by the retaining section, while the second housing and the second row contacts being configured to have said second row contacts upwardly inserted into the terminal grooves on the lower side with second solder tails positioned by the retaining section.

An electrical connector comprising:

• a one-piece unitary insulative housing defining a first L-shaped configuration in a side view and including a rear vertical retention section and a front horizontal tongue portion extending therefrom, the vertical retention section defining opposite front and rear faces thereof and the horizontal tongue portion defining opposite upper and lower faces thereof, a plurality of rear slots and a plurality of front slots formed in the corresponding rear and front faces, respectively, a plurality of upper grooves and a plurality of lower grooves formed in the corresponding upper and lower faces, respectively;
• a plurality of upper contacts defining a second L-shaped configuration in the side view, each of said upper contacts defining a horizontal upper contacting sections disposed in the corresponding upper groove and a vertical rear retention/tail section disposed in the corresponding rear slot;
• and
• a plurality of lower contacts defining a third L-shaped configuration in the side view, each of said lower contacts defining a horizontal lower contacting section disposed in the corresponding lower groove and a vertical front retention/tail section disposed in the corresponding front slot;
• wherein
• the upper grooves and the rear slots are configured to allow the corresponding upper contacts to be assembled thereinto in only a downward vertical direction, respectively, and the lower grooves and the front slots are configured to allow the corresponding lower contacts to be assembled thereinto in only an upward vertical direction opposite to said downward vertical direction.
