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.

Abstract: A connector of a modular machine board disposed on an inner edge of a back board of a display apparatus of an electronic device contacts with joint points of the electronic device, such that metal resilient pieces of said connector are assured to tightly contact with said joint points by means of the resilience of resilient component. As a result, even under vibration, the resilient component can regulate the up-and-down position of said connector along with vibration force to enable the metal resilient pieces to maintain a tight contact at the joint points of the electronic device.
