"Contact member, especially solder tongue"

The innovation relates to a contact member, in particular a soldering tongue for printed wiring, which consists of an essentially strip-shaped metal part, split in the longitudinal direction and consequently resilient in the lateral direction, with at least one metal part serving as a barb,
there is a lateral approach.

The fork-shaped split end of such a contact member can be fastened in an opening, for example an earpiece plate, the diameter of which is somewhat smaller than the width of the relevant end. The legs separated by the gap are bent so far towards each other during the introduction that the barbs of one or both of them
Legs can go through the opening, whereupon the tendons move apart again and the barbs prevent pulling out.

In the known contact members of this type, the space must between the limbs of the limb separated by the gap must be so large that the limbs do not close when they are inserted touch each other, as otherwise they would no longer be able to move elastically towards each other. With miniaturization are getting smaller and smaller, especially for circuit boards with printed wiring for the soldering tongues of individual parts becoming openings available, which in many lallen shut

are narrow to allow these relatively "wide soldering tongues to pass through.

According to the innovation, this disadvantage is eliminated in that at least one of the two is separated by the gap Leg of the contact member is bent so that the free ends of the legs - at least one which Ends a barb-shaped extension is formed - see like a pair of scissors can slide laterally on top of each other. With this type of construction needs between the legs no space to be left in the lateral direction and the legs can look partially overlapping, whereby the door to half the required width of the part to be inserted - i.e. to only slightly more than the width of one single leg - can be restricted.

The innovation is explained in more detail on the basis of the accompanying drawing in which

the fig. 1 to 4 represent four exemplary embodiments and the Pig. 5 and 6 to illustrate the attachment of a Serve solder tongue in an opening.

The one in Pig. 1 shown soldering tongue 1 can be a rope of a Form an individual part (not shown further), e.g. a high-frequency coil, for mounting on an insulating Chassis plate with surface wiring, e.g. printed wiring. The soldering tongue 1 is essentially strip-shaped; and is split longitudinally over part of the length. The gap has a wide part 3 and one up to the free one (in Pig. 1 the lower one). End of the tongue continuous narrow part 5 and it divides the tongue in two Legs 7 and 9, which are near the mentioned free end, preferably in the way shown, a considerably smaller one

Have overall width than the further part of the solder tongue 1. At the free end of at least one of the legs 7 and 9 - preferably on both - there is a barb-like lateral one Approach 11 or 15 seen goal

At least one of the legs 7 and 9 is bent in such a way that that! the legs slide over each other in a resilient manner can, in general, the tongue 1 is compressed in the width direction in a manner according to one of FIGS. 1 to 3, that the legs overlap somewhat. However, it is already sufficient if - as in Pig »4 in a Side view is shown - the lying along the gap part 5 part of one of the legs 7 and 9 parallel to see itself is shifted backwards over a small distance in relation to the other leg, so that] when pressed together the legs look like the legs of a pair of scissors pushing or sliding over each other.

Figures 5 and 6 show this process when the soldering tongue is inserted into an opening 17 in a mounting plate 19 according to Figure 2 is, ζ · Β · is provided with printed wiring 21 on the lower side. From a comparison between the Mg. 2 and FIG. 5 shows that the width of the opening 17 can be considerably smaller than the overall width of the legs 7 and 9 at the location of the barbs 11 and 15 and actually only needs to be slightly larger than the width of a single one Barb. After the legs 7 and 9 have passed through the open * tion 17 are performed, the resiliently compressed tongue can be wholly or partially (depending on the size of the opening 17) Relax, whereby the barbs 11 and 15 prevent the tongue from being pulled out · After all the individual parts have been attached have been, the barbs can e.g. be soldered to the wiring 21 by dipping »

Claims (2)

P.Ä. 134 092 * 3/16/65 Protection claims: 1 · Contact member, especially solder tongue for printed Wiring, which consists of an essentially strip-shaped, Split in the longitudinal direction and thus resilient in the lateral direction metal part with at least one barbed hook serving, lateral approach, characterized in that at least one of the legs of the contact member separated by the gap is bent in such a way that that the free ends of the legs - at least one of which ends a barb-like approach gate is seen laterally can slide springy over each other. 2. Contact member according to claim 1, characterized in that the legs of the contact member are in the relaxed state partially overlap.
