The invention relates to a magazine arrangement for enabling one or more printed circuit boards to be held in the magazine but readily removable therefrom, wherein the circuit boards are disposed side-by-side and can be inserted into and withdrawn from the magazine by virtue of each board having upper and lower edge-parts which coact with upper and lower grooves in the magazine. Each board carries on its edge that faces inwardly of the magazine one part of a connecting element which is intended to be brought into and out of coaction with a second part of the connecting element, this latter part being located on the backplane of the magazine. The two parts of the connecting element are each provided with a corresponding connecting device, wherein devices are provided for damping transient voltages that occur within board-mounted and/or board-connected electrical and/or electronic components, among other things, when a normalized voltage is applied to said components. The devices include at least one current-supply rail or contact strip which is to be received in a magazine-mounted groove or channel for voltage application. At least one board is provided adjacent an edge-part thereof that coacts with the groove or channel with a contact strip-part which can coact with the rail and through which a voltage is applied directly to the board-mounted electric and/or electronic components. When viewed in the direction in which a board is inserted into the magazine, the contact strip-part is preceded by a further contact strip-part coacting with the rail or the coact strip, wherein the two contact strip-parts are connected electrically by circuit-board related connection, enabling the board to be supplied with a voltage to dampen transient voltages that occur within the components. |
