Abstract: The present invention relates to a low-warpage housing part (1) for an electrical connector (2). The housing part (1) is injection molded from a plastic material reinforced with fibers (64), and includes a base section (14) having two flat sides (16) arranged on opposite sides. Housing sections (26a, 26b) extend away from each of the flat sides (16), respectively, and main fiber orientations (68a, 68b) of the housing sections (26a, 26b) corresponding to an average value of the orientations (66) of the fibers (64) in the respective housing sections (26a, 26b) are oriented away from the base section (14). The above orientations of the fibers (64) in the housing sections (26a, 26b) are used to selectively influence the warpage behavior of the housing part (1) in order to reduce the cooling-related warping of the housing part (1) according to the present invention. Due to the orientations of the fibers (64) of one of the housing sections (26b), in particular when the housing part (1) is cooled, a counter-warpage is induced in the above manner, thereby compensating for, or at least reducing, the warping of the other housing section (26a).
