Abstract: The invention pertains to a header or receptacle for use in a power connector, comprising a housing provided with at least two power contact elements having a mating end, a retaining portion for retaining the contact element in the housing, and a tail for connecting the contact element to a printed circuit board, cable, or the like. The retaining portion of the contact element and, preferably, also the mating end are cylindrical and a fixation element is placed between the tails, thus fixing the position of the tails relative to one another and avoiding contact between the mating ends of the contact elements.

Abstract: A system or connector/board assembly for electrically detachably interconnecting component boards (1) having connectors (10, 13) positioned opposite one another on both sides of a board (1). The connectors (10, 13) are each mounted rigidly on the board (1) because at least one terminal end (24) of a contact element (16, 18; 17, 19) of a connector (10, 13) is received in a hole (27) of a pattern (26) of holes (27) provided in the board (1), which terminal end (24) is provided with means (25) for the clamping mounting thereof in the respective hole (27). In this manner, connectors (10, 13) can be mounted adjacently on the component board (1) without the loss of position of a contact element.
