Title: MECHANICAL BUSH FOR CENTERING HELIX CABLE
Abstract:
An electric power device (500) may include a power source (510), a working assembly (520) powered by the power source (510) via a power cable (540), and a telescopic member (530) extending at least in part between the power source (510) and the working assembly (520). The telescopic member (530) may be extendable between an extended state and a non-extended state. The power cable (540) may be extendible and collapsible to at least some degree to accommodate extension and collapsing of the telescopic member (530) between the extended state and the non-extended state, respectively. The power cable (540) may include a transition region (230) where the power cable (540) transitions to a helix portion (220). The telescopic member (530) may include a cable centering assembly (550) that is disposed proximate to the transition region (230) to inhibit damage to the power cable (540) responsive to the telescopic member (530) collapsing to the non-extended state.
