A rear plane wiht rectangular electrical connectors is fixed to the rear part of the frame in which the circuit board is inserted. Fixtures for guide rails are positioned in the required locations on the frame components. The guide rails have a track in which the longitudinal edges of the circuit board on a slide. At the rear ned of each guide rail (8) is a holder (18) with two fork-shaped projections (19) extending in the guide rail longitudinal direction on each side of the connectors (5) on the rear plane (4). The holder retains the guide rail laterally in relation to the connection when fixed on the front and rear frame parts. The inside of the one fork-shaped projection locates along an extension line of one side of the guide rail track (15). On the other side of the track are elastically deformable projections (23). |
