Abstract: A connection arrangement includes a first plastic component, a second plastic component, and a closed induction ring. The first plastic component has a first joining region designed as a receptacle, and at one end, the second plastic component has a second joining region introduced into the first joining region. At the joining regions, the induction ring is at least partially fused into the two plastic components such that at one contact region between a first plastic melt of the first plastic component and a second plastic melt of the second plastic melt, a material-conclusive connection is generated. In this case, the induction ring is melted into the first plastic component while forming at least one first undercut, and is melted into the second plastic component while forming at least one second undercut such that between the plastic components and the induction ring, one each form-fitting connection is created.

Abstract: A connecting arrangement includes a first plastic component, a second plastic component, and a closed induction ring that is arranged between the first and second plastic components in a joining gap that is partially filled with molten plastic. The first plastic component has a first joining region that is configured as a stepped receiving opening with a first joining contour. The second plastic component has a second joining region that is configured as a stepped shoulder with a second joining contour. The second joining region is inserted into the first joining region to form the joining gap. The first and second joining contours are adapted to one another so as to center the first joining region, the second joining region, and the induction ring in the joining gap with respect to one another. A method in one embodiment includes welding the first and second plastic components of the connecting arrangement.

Multiple contact areas are formed between an outer surface of the objective and the cylindrical inner surface of the tube area of the objective holder by frictional engagement. For this purpose, a first clamping plane is formed in the tube area, and a second clamping plane is formed which is offset from the first clamping plane along a longitudinal axis of the tube area, multiple first contact areas being formed in the first clamping plane, and multiple second contact areas being formed in the second clamping plane and situated distributed around the longitudinal axis in a circumferential direction.

The spark plug has a contact region for contacting with the spring of the ignition coil, which contact region has a recess surrounded by a closed, annular wall region for receiving the contact segment of the spring of the ignition coil.

Abstract: A device for storing energy and transforming energy, e.g., an ignition coil of an ignition system of a vehicle, includes: a magnetically active I core; a first coil element which accommodates a first winding that is connected to a supply voltage; a second coil element which has a second winding that is connected to a high-voltage terminal; a peripheral core which encloses the I core, the first winding and the second winding; a permanent magnet which is situated at one end of the I core; a first insulation situated between the permanent magnet and the peripheral core; and a second insulation situated between the other end of the I core and the peripheral core.

Abstract: An ignition coil, in particular for an internal combustion engine of a motor vehicle, has an inner magnet core which is concentrically enclosed by a primary coil and a secondary coil. The inner magnet coil is made up of sheet-metal strips stacked on top of each other, the sheet-metal strips forming a substantially rectangular or square cross-section surface of the inner magnet core. At least the lower and the upper sheet-metal strips, delimiting the inner magnet core, have, at least in partial areas, a reduced width viewed in the longitudinal direction compared to the other sheet-metal strips of the inner magnet core. This makes a primary bobbin and a secondary bobbin having an enlarged corner radius and a more uniform winding density of the primary coil and the secondary coil possible.
