  • Electrical feed through connector
    Patent number: 12431639
    Abstract: Apparatus for resilient electrical and mechanical connection is disclosed where a mount is configured with a central connector and at least one post. The central connector is configured to pass through an opening in a surface and engage threaded connection with a recessed nut. One or more posts are configured to pass through additional openings in the surface and engage a co-radial groove in the recessed nut that allows for tightening of the recessed nut to the mount on opposite sides of the surface while receiving the one or more posts.

  • Compliant electrical connector and a socket assembly therefor
    Patent number: 5427541
    Abstract: An electrical connector assembly which is adaptive to accommodate variations in the diameters of, and in the spacing between, pins with which it mates. The sockets of the assembly are formed with elongated fingers which deflect for larger diameter pins and are mounted to the connector housing in such a way that they have limited freedom of movement orthogonally to the longitudinal axes of the sockets to accept variations in the pin spacing.
