Abstract

This article describes an enclosure assembly which captures and locks a printed circuit board (PCB) in the enclosure. Once the PCB is latched in the enclosure, it functions as part of the fastening mechanism, thereby creating a tamper-proof container.

Content Self-Capturing/Locking Enclosure

       This article describes an enclosure assembly which
captures and locks a printed circuit board (PCB) in the enclosure.
Once the PCB is latched in the enclosure, it functions as part of the
fastening mechanism, thereby creating a tamper-proof container.

      Existing solutions include epoxy filling of the container after
the PCB is installed, use of tamper-proof screws to hold the two
container halves together and bonding the container with adhesive and
ultrasonic welding of the two container halves.

      The drawing is an exploded perspective view of the enclosure
assembly disclosed herein.  Two alike molded parts 1 and 2 are shown.
Molded openings are located at either end of parts 1 and 2 and clamp
cable in and cable out from the PCB assembly in place during
assembly.  The arrow shows the load direction of molded part 2.
Diagonally located locking fingers 3 of the molded parts 1 and 2 snap
onto the PCB and provide a mechanical interface that holds the entire
assembly firmly locked together.
