Abstract

A power pack subassembly (10) for a drug delivery device (100) is described, the pack subassembly (10) extending axially along a shaft (12) from a proximal end (14) to a distal end (16). The power pack subassembly (10) comprises a housing (20) extending from a distal end of the power pack subassembly (10), a locking ring (60) axially slidable relative to the housing (20), an activation ring (40) axially slidable relative to the housing (20) and relative to the locking ring (60), the locking ring (60) being located closer to the distal end of the power pack subassembly (10) than the activation ring (40), a connection mechanism that connects the activation ring (40) to the locking ring (60) in use, the connection mechanism including a connector on the activation ring (40) and a mating connector on the locking ring (60), and a locking mechanism that locks the power pack subassembly (10) after use, the locking mechanism including a distally oriented surface (72) of the locking ring (60) and a corresponding proximally oriented surface (24) of the housing (20).
