Connector assembly having surface mounted terminals

A connector assembly comprising:

• a housing including an array of at least first terminal-receiving passageways extending therethrough from a mating face to a mounting face and an array of at least first spring arm receiving recesses at least adjacent to said mounting face, one of each of said first recesses being associated with and in communication with each said first passageway;
• an array of at least first terminal members, each having an axially extending body section having first and second opposed ends defining first and second contact sections, said first contact section being adapted for surface mount engagement with a corresponding contact pad of a circuit board, said first terminal members being disposed in associated ones of said first passageways of said housing such that said first contact section extends slightly beyond said mounting face for circuit board engagement, each said first passageway being dimensioned to be just larger than the dimension of the terminal body section permitting insertion therethrough from said mounting face during assembly, said first terminal members further including a stop surface proximate said first contact section and cooperable with a corresponding stop means within said housing to stop axial movement in a direction from said mounting face to said mating face;
• each said first terminal member further including a spring arm having a first transverse portion extending laterally from said first end of said body section, an axial portion of a selected length extending toward said second end from said first transverse portion, and a second transverse portion extending toward said body section and angled slightly toward said second end, said first transverse portion extending essentially parallel to said mounting face and recessed therefrom, said second transverse portion being adapted to engage with a biasing surface of said housing and said axial portion including a retention means facing said mounting face and cooperating with retention means of said housing to stop axial movement of said spring arm in a direction toward said mounting face;
• whereby
• upon mounting said connector to said circuit board with said first contact section mated to said corresponding circuit pad, said biasing surface of said housing engages said second transverse portion and exerts pressure thereagainst to bias said first contact section against said circuit pad, said spring arm providing increased normal force to the contact interface while remaining outside the path of the flow of current between the terminal and the circuit pad.
