Abstract
An electrical device is proposed which has a housing (1), comprising at least two housing parts (2, 3), and an electronic circuit disposed in the housing (1). A connection device (5) for supplying voltage to the device and/or for signal transmission to the electronic circuit is present that can be secured to the housing (1); the housing parts (2, 3) are joined to one another by laser welding at a joining edge (4). The connection device (5) is provided with a welding flange (8), which comes to rest between the housing parts (2, 3) in such a way that an at least nonpositive connection of the housing parts (2, 3), with enclosure of the connection device (5), can be produced.
Claims8
An electrical device, having
- a housing (1), comprising at least two housing parts (2, 3), and an electronic circuit that can be disposed in the housing (1), and having
- a connection device (5), which can be secured to the housing (1), for supplying a voltage to the device and/or signal transmission to the electronic circuit, characterized in that
- the housing parts (2, 3) are joined to one another by laser welding at a joining edge (4), said housing parts being connected by a weld seam;
- wherein the connection device (5) has an injection-molded part with plug contacts or connecting lines, wherein the connection device (5) holds a welding flange (8) by means of encompassing cast regions, said welding flange (8) completely surrounds the connection device (5), wherein the welding flange (8) is encompassed by the last two housing parts (2, 3), said at least two housing parts (2, 3) and the welding flange (8) comprising a metal, and wherein the at least two housing parts (2, 3) and the welding flange (8) are sealingly connected to one another by means of a welding seam, wherein the housing parts (2, 3) and the welding flange (8) completely surround and enclose the connection device (5).
