<p>A box (1) for a switch comprises a bottom (2) carrying a printed circuit (3) to which are secured connection blocks (8). The bottom (2) extend between two side walls (24). The other two walls of the box (1) are provided with apertures and are comprised of slides (11) intended to guide the input/output cards towards the blocks (8). The bottom (2) further comprises an inner wall (13) arranged between the circuit (3) and the inside of the box. The blocks (8) are applied against the contour of the ports (14) and are accessible through the latter inside the box (1). Each slide (11) carries a pin (31) engaged into a drilling (24) of one of the blocks (8). The slides (11) are provided with a certain play (J) therebetween on the side of the wall (13). At their end opposite to the latter, they bear against each other. Utilisation to enable the slides to follow motions for example of thermal origins to which the circuit (3) is subjected yet without securing the slides to the latter. </p> |
