Wedgelocks B, C, D, Series
C/A Design offers their wedgelock B, C, D card retainer series
C/A Design wedgelock card retainers offer very high locking force for cold wall applications. In a typical application, they will mount either directly to the PCB or to a heat frame assembly with screws or rivets and are then inserted into a machined channel of a cold wall within a rugged enclosure. When expanded, the wedgelock will clamp the PCB in place providing resistance to shock and vibration, as well as a thermal path for heat transfer between the PCB and the cold wall.
Wedgelocks are available in various profiles and allow for configurable length, mounting, and plating selections. For configurations not shown below within the datasheets, please contact DigiKey for more information.
