Abstract

The present invention discloses a direct-current (DC) electric connector that includes plurality of conductive and insulation layers constituting a near-zero inductance connector. The connector further includes a top and a bottom insulation-and-protection covers covering and protecting the plurality of conductive and insulation layers. The top and bottom insulation-and-protection covers having a tapered outer surface for providing a tapered profile along a horizontal direction toward a connector opening for receiving a printed circuit board into the near-zero inductance connector. The connector further includes a locking cartridge for adaptively enclosing the near-zero inductance connector with the printed circuit board inserted therein. The locking cartridge has top and bottom surfaces each engages the top and bottom insulation-and-protection covers respectively for horizontally pushing toward a direction having a gradually increased profile height for generating a vertical pressing force. The vertical pressing force is applied to securely pressing and locking the top and bottom insulation-and-protection covers to the plurality of conductive and insulation layers with the printed circuit board inserted therein.
