Patent ID: 7554800

Claim:
An electrical and mechanical attachment mechanism for coupling a module to an electrical device comprising: at least one pawl receiving chamber within the electrical device; a plurality of moveable pawls disposed on the module and configured to be inserted in the at least one pawl receiving chamber to engage a surface of the at least one pawl receiving chamber, the plurality of moveable pawls having a resilient bias along a first axis in a first direction; at least one button coupled to the plurality of pawls and configured to displace the plurality of moveable pawls to a retracted position; a lock release pin projecting from the module and resiliently biased along a second axis, the lock release pin being configured to release the pawls from the retracted position in response to the lock release pin being pushed into the module along the second axis to a particular distance and thereby allowing the resilient bias along the first axis to move the pawls in the first direction; at least one signal coupling pin projecting from the module and having a predetermined spatial relationship to the plurality of pawls; and at least one signal coupling pad disposed within the receiving chamber and configured to interface with the at least one signal coupling pin and thereby electrically couple signals between the module and the electrical device.
