Electrical socket assembly for electrically connecting adjacent circuit boards

A circuit board assembly comprising:

• first and second circuit boards;
• an elongated power contact coupled to the first circuit board;
• a socket housing comprising coupling and flange portions and having a contact cavity that extends through the coupling and flange portions along a central axis, the coupling and flange portions having different peripheral contours that extend about the central axis, the peripheral contour of the coupling portion being sized and shaped to permit the coupling portion to be inserted through a thru-hole of the second circuit board, the peripheral contour of the flange portion being sized and shaped to prevent the flange portion from advancing through the thru-hole of the second circuit board;
• and
• a fastener configured to be secured to the coupling portion, the fastener and the flange portion having respective mating surfaces that face each other in opposite directions along the central axis, the mating surfaces being configured to grip the second circuit board therebetween such that the socket housing has a fixed position with respect to the second circuit board;
• wherein a conductive path exists between the first and second circuit boards through the power contact and the socket housing when the power contact is inserted into the contact cavity and electrically engaged to the socket housing, the first and second circuit boards extending substantially parallel to each other and having a stack spacing therebetween.
