Abstract
A case locking device is provided. For example, an outer case and an inner case used for various types of electronic devices, such as set-top boxes (STB), are connected by a lock using a resilient force from an elastic material, such as a spring, so that the outer case and the inner case may be separated from each other using only a separately provided jig. Accordingly, the outer case and the inner case may be connected to each other more easily and any general user may be prevented from separating the case arbitrarily, thus making it possible to effectively prevent catastrophic failures from occurring at the electronic device due to a user's arbitrary manipulation.
Claims20
A case locking device for securing an inner case of a housing to an outer case of the housing, the case locking device comprising:
- a lock that secures the inner case to the outer case with a pressing force, the lock comprising a plurality of laterally spaced-apart protrusions protruding in a same direction through a plurality of laterally-spaced apertures provided in a front cover of the lock, wherein each of the plurality of protrusions has an inclined surface and each of the plurality of protrusions shares a contiguous base portion, and an elastic material that pushes the plurality of protrusions toward a wall of the outer case, wherein the inclined surface of at least one protrusion of the plurality of protrusions is at a different angle of inclination than an angle of inclination of the other protrusions.
A case locking device for securing an inner case of a housing to an outer case of the housing, the case locking device comprising:
- a lock comprising a hook having a first protrusion and at least one second protrusion, which are laterally spaced apart and share a contiguous base portion, the first protrusion and the at least one second protrusion protruding in a same direction through a plurality of corresponding laterally-spaced apertures provided in a front cover of the lock, the hook having an extended position and a retracted position, the hook being biased by a spring into the extended position, the first protrusion having an inclined surface on one side of the first protrusion, the at least one second protrusion having an inclined surface on one side of the at least one second protrusion, the one side of the first protrusion facing in a direction opposite to the one side of the at least one second protrusion, wherein the inclined surface of the first protrusion engages an edge of the outer case that forces the hook into a retracted position until the first protrusion is aligned with a first fastener opening formed in the outer case whereupon the spring forces the hook into the extended position and the first protrusion enters the first fastener opening and the at least one second protrusion enters a corresponding second fastener opening formed in the outer case, securing the outer case to the inner case.
