Examples of the present disclosure describe a flexible connector mechanism that may be used to form an electrical connection and/or a communication link between one or more devices. The flexible connector mechanism may comprise one or more interface components that may each comprise one or more contact portions. The interface components may be configured to be selectively coupled to one or more corresponding components of a coupleable object. The flexible connector mechanism may also comprise a flexible portion that enables the interface components to be manipulated along one or more planes or axes. The flexibility of the flexible portion may enable the interface components of the flexible connector mechanism to be adjusted into, and maintained in, an optimal (or operable) position when coupled to a coupleable object in motion.

A busbar for use in mechanically and electrically connecting components in a device or system. The busbar includes a plurality of conductors arranged to provide two opposed end portions and an intermediate portion, wherein each of the conductors has a plurality of intermediate extents that traverse the intermediate portion. The intermediate portion including: (A) an unfused segment where no intermediate extents of the conductors are fused together to form a single consolidated conductor, and (B) a fused segment that includes (i) a partial solidification zone where a majority of the intermediate extents of the conductors are fused together to form a partially solidified region that provides a single consolidated conductor, (ii) a full solidification zone where all of intermediate extents of the conductors are fused together to form a fully solidified region that provides a single consolidated conductor, and (iii) an unsolidified region where all of the intermediate extents of the conductors are not fused together.
