Disclosed is an improved electric connector having pin-terminals press-fit in an 'L'-shaped housing. The vertical wall of the housing comprises a first longitudinal support beam and a lateral arrangement of first flexible joints, which are separated by first slits and integrally connected to the first longitudinal support beam. The horizontal floor of the housing comprises a second longitudinal support beam, a lateral arrangement of second flexible joints, which are separated by second slits, and are integrally connected to the second longitudinal support beam and a lateral arrangement of terminal holding sleeves, each sleeve having a terminal receiving aperture. The terminal holding sleeves are integrally connected both to the first joints of the vertical wall and the second joints of the horizontal floor, thus lying therebetween. The 'L' shaped housing structure gives the electric connector good mechanical strength while allowing the terminal holding sleeves to the displaced laterally, thereby absorbing any stresses appearing between the pin-terminals and selected conductors of the printed circuit, which stresses otherwise would cause the peeling-off or cracking in soldered portions.
