  The Majorana Demonstrator is an experiment constructed to search for
neutrinoless double-beta decays in germanium-76 and to demonstrate the
feasibility to deploy a ton-scale experiment in a phased and modular fashion.
It consists of two modular arrays of natural and 76Ge-enriched germanium p-type
point contact detectors totaling 44.1 kg, located at the 4850 level of the
Sanford Underground Research Facility in Lead, South Dakota, USA. The
Demonstrator uses custom high voltage cables to bias the detectors, as well as
custom signal cables and connectors to read out the charge deposited at the
point contact of each detector. These low-mass cables and connectors must meet
stringent radiopurity requirements while being subjected to thermal and
mechanical stress. A number of issues have been identified with the currently
installed cables and connectors. An improved set of cables and connectors for
the Majorana Demonstrator are being developed with the aim of increasing their
overall reliability and connectivity. We will discuss some of the issues
encountered with the current cables and connectors as well as our improved
designs and their initial performance.
