1. A connector, comprising:
a plurality of contact assemblies, wherein each of the contact assemblies comprises an outer contact housing, a separate inner contact housing attached to the outer contact housing, and a connector contact; and
a plurality of non-conductive stack spacers separating the contact assemblies from each other, the contact assemblies and the stack spacers forming a connector stack defining a connector lumen configured to receive a portion of an electrical stimulation lead, wherein the contact assemblies and stack spacers are brazed together forming a sealed connector stack that resists passage of fluid between the contact assemblies and stack spacers, wherein, for each of the contact assemblies, the outer contact housing has a longer width, along the connector lumen, than the inner contact housing.
