A cable holderfor a large number of connection cablesof an electrical or electronic control device, in particular of an electronic ballast of a lamp. The cable holderhas a base bodyin which receptaclesare formed which surround, at least in sections, an insulating sheath of the connection cablesand are associated with apertureswhich open out into an end faceof the base bodycable endsfrom which the insulation has been stripped, of the connection cablesextending through the apertures

Cable holder

An electrical device such as a ballast for fluorescent lamps and including a housing, a terminal, and a catch element for connecting the terminal to the housing, the catch element including a catch leg for connecting the terminal to the catch element and for connecting the catch element to the housing. Accordingly, the electrical device is designed such that the individual terminal sites of the terminal have minimal positional tolerance so that the terminal can be wired with an automatic installation machine without the danger of misinsertions.

Electrical device and unit consisting of an electrical device and lamp diffuser

An electric module which includes a printed circuit board and at least one electrical subassembly arranged thereon is disposed within a metallic housing and is grounded to the metallic housing by way of a wire bridge which extends transversely across a cutout disposed in the printed circuit board. The metallic housing is integrally connected to a contact tongue which extends through the cutout and the printed circuit board before engaging the wire bridge. The wire bridge connects one side of the printed circuit board to a ground conductor track disposed on the opposing side of the printed circuit board. Preferably, the contact tongue includes two closely spaced contact elements that are spaced apart for frictionally receiving the wire bridge therebetween. Further, the cutout extends transversely across the contact bridge at an angle so the flat plug-like contact element also extends across the wire bridge transversely at an angle for improved frictional engagement between the wire bridge and the two contact elements. Preferably, the contact elements cut into or mar the wire bridge upon insertion.
