This invention is a wireless communication device ( ) that includes a housing ( ) and a compartment ( ) accessible from one side of the housing. The device also includes a compartment cover ( ) that has a covering position over the compartment and a latching assembly ( ) that is supported by the housing. The latching assembly is capable of receiving an end portion ( ) of the compartment cover such that the latching assembly requires less interactive force to receive the end portion than to release the end portion. In addition, the latching assembly includes an inner component ( ) positioned adjacent to the housing and an outer component ( ) positioned adjacent to the inner component. The inner component moves together with the outer component to release the end portion of the compartment cover and moves separate from the outer component to receive the end portion of the compartment cover.

A step joint between two plastic pieces suitable for an ultrasonic weld joint. A first plastic piece includes a series of ribs, each rib having generally horizontal top surface. A generally vertical section extends upward behind the ribs. A second plastic piece includes a generally horizontal section for mating with the ribs, the horizontal section of the second plastic piece covering the generally horizontal section of two or more ribs. The second plastic piece also includes a generally vertical section suitable for mating with the generally vertical section of the second plastic piece. A plastic assembly according to another aspect of the present invention includes the first plastic piece and the second plastic piece, a joint between the first and second plastic pieces formed by an abutment between the generally horizontal surface of the second plastic piece and the top surface of the one or more ribs, and between the generally vertical surface of the second plastic piece and the strip of the second plastic piece, and a weld between the first plastic piece and the second plastic piece formed by melted plastic from a partial melt of the first plastic piece and the second plastic piece, the melted plastic flowing into the joint between the first plastic piece and the second plastic piece and hardening to form the weld.

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.
