ⁿ Stand construction element, preferably for use in printed circuits "

The innovation relates to passive permanent elements, e.g. resistors, capacitors, wires or the like, which are preferably intended for insertion in printed circuit boards and which are finally attached by soldering after insertion. The insertion into the grid dimension should be quick and easy, however, a consistency must be guaranteed and a misalignment or later tilting must be avoided at all costs. This is achieved by a special design of the free end of at least one of the two connecting wires .

Figures 4 and 5 are sectional views on the üchnittsteI Le I ... II of FIG. 3.

A characteristic of the innovation is that the lead wires to be stamped consist of a relatively strong and easily cold-deformable wire material L, which allows against A simple embossing process at the end of the production process to switch on, through which the still free end at least one of the two wires is deformed in such a way that It is lancet-shaped and pointed, with longitudinal edges made of barrel t.

According to FIG. 2, both wires are in this at the still free end Kind of deformed. The 2nd wire (2a) is bent around 160 and runs parallel to the 1st wire ζ2) in such a way that the finished Component easily and safely in the grid dimension of the relevant Scha Itp latte can be inserted.

In an improving configuration of the innovation, FIG. 1 shows that a secure and tilt-free fixation of the relevant component can already be achieved after insertion if only one wire (2) is deformed in the above-mentioned manner (lancet 3). The 2nd wire (5) remains unembossed and can therefore be kept weaker in diameter and only have a loose -'Tuchfüh ment ' ¹ in the associated grid hole,' if necessary. the wire of another component can be inserted into this hole.

This design of the 2nd wire (5) according to also wiring variations insofar as its free end wan Iwei se is not electrically contacted in the mentioned grid hole, but at another point of the grid or the relevant overall device . It is recommended to use this

The technical progress is confirmed by the following advantages:

ο ) The good keel effect of the slim lancet shape as well as its sharp longitudinal edges ensure an immediate effect. Reliable, tilt-free fixation of the uauelementes up to soldering as well as soldering on several edges.

2.) ViQifach a lancet of this type is sufficient to ensure that everything is done "

3.) The wedge shape of the lancet bridges a wide tolerance range (e.g. 0.8 to 1.3 mm diameter) of the punched toaster holes .

A-.) With a triangular design of the lancet (rig. 5) results The 3-point Klernmunn (within the cylindrical bore).

5.) The work of the user is made easier, without any loss of 3 security.

6.) The design according to FIGS. 1 and 3 allows the mentioned interconnection variations in the simplest possible way, without any change to the element .
