In an enclosure, electrical connections to a bulkhead connector may be made using a flex spring. The flex spring may have a frame and one or more spring members supported at their proximal ends by the frame. At their distal ends, the spring members may be configured to apply a distributed load to compress a set of contacts on a flex assembly against a corresponding set of contacts on a bulkhead connector. The pressure applied by the flex spring may be distributed to make reliable electrical connection between the corresponding sets of contacts. In one embodiment, the frame of the flex spring may be attached to a flex bracket. The flex bracket may mount to a wall of a base to which the bulkhead connector is mounted.
