Abstract
A fastener for detachably coupling a housing, such as a battery pack, to an appliance, such as a wireless terminal, is disclosed. In use, the fastener is disposed in a housing. When a user applies a force to the fastener to release the housing from the appliance, the fastener rotates about an axis, causing an engagement feature of the fastener to rotate away from the appliance, thereby decoupling the fastener from the appliance. The fastener includes a biasing member which provides a restoring force that keeps the fastener coupled to the appliance in the absence of a decoupling force. In some embodiments, the fastener includes various features suitable for reducing stress that accumulates in the biasing member as it rotates during decoupling. Such features include a stress-reducing surface, and an offset between the stress-reducing surface and the axis of rotation.
