Supply device for fastening to a planar carrier arrangement having electrical conductor tracks

Supply device (1) for fastening to a planar carrier arrangement (200) having electrical conductor tracks (233);

• wherein the supply device (1) comprises a housing (2), contacting elements (3) and an arrangement (5) of electrical and/or electronic components that is electrically coupled to the contacting elements (3), and the supply device can be or is coupled to an electrical consumer (377) for the supply thereof;
• wherein the contacting elements (3) are each provided for piercing into a surface (237) of the carrier arrangement (200) and are each embodied as pointed and/or sharp;
• wherein the contacting elements (3) can be brought into a non-contacting position in which the contacting elements (3) are received in the housing (2);
• wherein the contacting elements (3) can be brought into a contacting position and for this purpose can be extended out of the housing (2) by means of manual action on the supply device (1) in order to pierce into the surface (237) of the carrier arrangement (200) by means of the contacting elements (3) and to bring at least two of the contacting elements (3) into contact with in each case one of the conductor tracks (233);
• and
• wherein the supply device (1) comprises at least one safety arrangement (8), by means of which an extension of the contacting elements (3) is mechanically prevented in a blocking configuration thereof.
