Embodiment Construction

[0042] Figure 1A A device 1 is shown with a terminal area 2 for connecting the device 1 to a circuit board. Device 1 is, for example, an inductive device.

[0043] The terminal area 2 is designed in particular in the form of a terminal pin. The terminal area 2 can be inserted, for example, into a hole in a circuit board. In particular, the terminal area 2 is suitable for through-hole mounting. Terminal area 2 points downwards.

[0044] The terminal area 2 here has a rectangular cross-sectional shape. The terminal area 2 can also have other shapes depending on the desired connection design. The component 1 can have a plurality of terminal regions 2 .

[0045] In this case, two terminal areas 2 are provided, which are arranged next to each other.

[0046]The terminal area 2 has a litz wire 3 and a wrapping 4 arranged around it. The litz wires 3 protrude into the wrapping 4 . In particular, the ends of the litz wire 3 and the wrapping 4 are flush. In the case of a PTH i...

Abstract

The invention relates to an electric component (1) comprising a connection region (2) for connecting to a conductor plate. The connection region (2) comprises a stranded wire (3) and an enclosing piece (4) that surrounds the stranded wire (3). The enclosing piece (4) is connected to the stranded wire (3) for example by thermal diffusion bonding.

Description

technical field [0001] The invention relates to a terminal area for an electrical component. The device is, for example, an inductive device. The terminal region is designed for the electrical connection of the litz wires, in particular the high-frequency litz wires, of the component to the printed circuit board. For example, the litz wires form the windings of the device, especially the coils. Background technique [0002] In known methods for processing litz wires to produce terminal regions, the insulation of the litz wires is removed by immersion in a hot solder dipping bath. The process is difficult to control and often results in quality defects. Furthermore, cavities are usually left in the formed terminal area, so that the terminal area does not have a compact form. [0003] In other known methods, prefabricated cable lugs or ring cable lugs are used for terminating the stranded wires. Such preformed sleeves however increase the thickness of the terminal area an...
