Electrical connector with an improved terminal module

An electrical connector comprising:

• a housing defining a mating cavity opening forwards and a receiving cavity opening rearwards;
• and
• a terminal module comprising an insulator and a pair of terminals, the insulator comprising an upright portion and a horizontal portion extending forward from the upright portion, the horizontal portion having a ring rib, the terminal comprising a contacting portion extending from the insulator, a leg portion, and a middle portion connecting with the contacting portion and the leg portion, the middle portion comprising a horizontal section embedded in the insulator and an upright section bending from the horizontal section, the insulator being received in the receiving cavity, the contacting portions of the pair of the terminals protruding into the mating cavity;
• wherein the ring rib of the horizontal portion is interference fit with an inside of the receiving cavity of the housing and the upright portion presses forward against the housing to limit a forward-movement of the terminal module so that the terminal module is retained in the receiving cavity, and a front face of the horizontal portion is separated from the housing;
• and
• wherein the upright sections of the terminals are exposed rearwards and separated by a partitioning wall defined on the insulator.
