Electrical component for printed circuits

The furnace "relates to an electrical component which for equipping an insulating plate on the flat Conductors are attached, serves. The electrical component should be at a predeterminable distance from the insulating plate of

Electrical components in the sense of the innovation are electrical resistors, coils, components made of Perrit material,! Transistors and capacitors, eg electrolytic capacitors, paper wound capacitors or capacitors with plastic dielectric. The components to which the innovation "refers, generally have at least one wire-shaped connecting member, that the connection of the conductor tracks of the printed circuit is to the device and is inserted into contact holes of the printed circuit. For example, in electrolytic capacitors, or even when transistors and paper wound capacitors, this connection element can be in the form of a so-called rivet, ie a relatively short protruding thick piece of wire that is attached to the component.

It is known to press-button artigo on such a holding part Put on spring holders in the form of a slotted cap. To attach the cap to the holding part, it was attached to the Holding part angeraeten.

It has now been found that the riveted connection is electrically

According to the innovation it is therefore proposed that the slotted resilient cap is soldered or welded to a metallic holding part. Soldering is an option if the metallic holding part made of solderable metal "; in the other cases the connection is effected by welding ° Both by soldering and welding a galvanically perfect connection between the cap and causes the holding part.

The cap preferably consists of at least one strip, the end parts of which are bent around the holding part. To prevent the component from moving sideways it is particularly advantageous if the cap consists of at least one ■ there is at least three-armed stamped part, the (their) end parts are bent around the holding part.

With the help of the drawing, the firing should be shown using a few examples Preferred embodiments are explained:

The figures. 2 and 3 now show special embodiments for the cap, which is denoted by 7 in FIG. 1. According to FIG. 2, the cap 7 consists of a strip 9, the ends 10 and 11 of which are bent up to form the cap. In contrast, according to FIG. 3, the cap 7 is formed from a stamped part 12 with three arms in the present case, the end parts 13, 14 and 15 of which are bent up to form the cap ο
