Patent ID: 8164923

Claim:
A protection device intended to be attached to a support and to at least partially cover at least one electronic component, comprising: at least a first wall corresponding to a first printed circuit portion comprising at least one first conductive track at its surface, the first wall comprising at least first, fourth and fifth mechanical guide elements; at least a second wall corresponding to a second printed circuit portion comprising at least one second conductive track at its surface, the second wall comprising at least a second mechanical guide element which cooperates with the first mechanical guide element, the second wall further comprising a third mechanical guide element; a third wall corresponding to a third printed circuit portion comprising at least one third conductive track at its surface, the third wall comprising at least a sixth mechanical guide element, which cooperates with the third mechanical guide element, a seventh mechanical guide element which cooperates with the fourth mechanical guide element, and an eighth mechanical guide element; a fourth wall corresponding to a fourth printed circuit portion comprising at least one fourth conductive track at its surface, the fourth wall comprising at least a ninth mechanical guide element which cooperates with the eighth mechanical guide element, and a tenth mechanical guide element which cooperates with the fifth mechanical guide element; weld spots connecting the first wall to the second wall, at least one of the weld spots further electrically connecting the first conductive track to the second conductive track; and additional welding portions connecting the first wall to the third wall and to the fourth wall.
