Abstract
To prevent entry of contaminants into a craft unit, each of a telephone signal connector (RJ11 jack) and DIN-type digital signalling link connector is replaced with a sealed, multi-pin plug/receptacle type connector which integrates the routing of both telephone communication signals and digital communication signals between the craft unit and an external device. When stored in a storage and battery-charging station, the craft unit is maintained in a communication-ready state, by providing each of the battery-charging holder and the portable craft unit with an additional multi-pin interconnect arrangement, that contains a charging path for the craft unit's internal battery, and a multi-pin signalling path. This multi-pin interconnect arrangement contains both a set of communication signalling pins and a set of terminal pins through which the internal battery of the portable craft unit is charged. Within a receiving cup-like portion of the storage and battery charging unit, a plurality of male connector pins are nested in a compact linear arrangement to engage a corresponding set of female connector terminals supported within the portable craft unit.
