The box includes a printed circuit board (101) carrying integrated circuits, linked to a connector block (102) along one edge, carrying two rows of contacts (103, 203). The printed circuit board is enclosed between two further panels (104, 105).Electrical earth contacts (108, 209) are provided, linking two of the contact sockets (103, 203) to the respective panels (104, 105). The contacts are spring lamellae, pressing against the panels. A further spring contact (107) makes connection with the equivalent part of the printed circuit board.
