Compression connector configured with two housing liminted contacts therebetween

An electrical connector assembly comprising:

• a first housing defining a coupling face and a mounting face opposite to each other in a vertical direction;
• a plurality of first passageways extending through the first housing in the vertical direction, each of the first passageways being equipped with a first stopping step facing toward the coupling face;
• a second housing defining a coupling surface and a mating surface opposite to each other in the vertical direction;
• a plurality of second passageways extending through the second housing in the vertical direction, each of the second passageways being equipped with a second stopping step facing toward the coupling surface;
• and
• a plurality of contacts disposed in the corresponding first passageways, respectively, under condition that each of said contacts defining opposite resilient contacting sections and opposite retention sections;
• wherein
• the first housing and the second housing are assembled to each other with the coupling face and the coupling surface coupled together in the vertical direction, the first passageways and the second passageways are aligned with each other in the vertical direction, respectively, the opposite resilient contacting sections extend beyond the mating face and the mating surface in the vertical direction, respectively, and the opposite retention sections are sandwiched between the first stopping step and the second stopping step in the vertical direction wherein both the mating surface and the mounting face are equipped with corresponding standoffs, respectively;
• wherein said mounting face is further equipped with a mounting post while the mating surface is not;
• wherein the standoffs are located in middle regions of said mounting face and the mating surface;
• wherein the standoff on the first housing is located essentially outside of a corresponding end face while the standoff on the second housing is located essentially inside of a corresponding end face.
