Abstract
An electronic device (1) includes a set of boards (2) carrying electronic components (3). The boards are mounted so as to be separated from and parallel to one another. The electronic device (1) is capable of withstanding shocks in a defined direction approximately orthogonal to the planes of the boards (2). The electronic device (1) also includes a protective body (5) made of an elastomeric substance encapsulating the set of boards (2). The elastomeric substance fills the spaces between the boards (2) and forms at least one front shield (6), in the direction of the shocks (E) for the set of boards (2).
