Description

Solder connection for electrically conductive surfaces

The acidification concerns a solder connection for electrical contact conductive surfaces, especially toh sheet resistance plates.

There is a large area of application here, e.g. at Schichtöreh.- tmd Sliding resistors with which the applied to the insulating material carrier, thin resistance layer is provided with connecting elements, the 2mr solder connection can be used for other switching elements. In the far- in some cases, soldering is used for this purpose, which is or hollow rivets fastened in corresponding holes in the resistance plate will. 3in difficult! Noble with this? Ona of contacting lies in a sufficient contact pressure of the connection element on the layer throughout its life and under changing To maintain operating conditions of the resistor.

To overcome this difficulty it is known (Ga 1 850 8? 6), dea solder connection to assign an additional resilient organ, which constant pressure at the contact points receives. Such an arrangement solves the problem perfectly, but it is too expensive for many applications in cash register production.

The hiring is based on the task, a solder joint ait good To create contact security, the production and processing costs of which are low *

According to the hiring, it is proposed, in a solder connection for electrically conductive surfaces, in particular schihtwiderstandspl ten, in addition to the means for ntechanisehen fastening, to form an integral, resilient, resilient component which rests on the conductive surface under pretension. Am such sngexöT & tws ÄOEttsktvigssE causes apart from the chewing, minor additional wanä

Material no additional manufacturing and assembly costs. Through the
Separation of the functions, mechanical activation and contacting of the conductive surface, the organs intended for this can be optimally designed for their purpose and thus the overall properties of the
Solder connection can be improved.

In a first embodiment, staples are provided for fastening the solder connection, which form a web or tenon of the plate.
and / or frictionally, and laterally or in the central axis of the solder connection a resilient Xontaktana is formed, which
rests on the conductive surface under pretension after the clamps have been folded down.

In a further embodiment, we «* suggested» for fastening
the solder connection is to be provided with a pivot pin engaging in a recess in the plate and the solder connection must be attached to a resilient contact arm at the very least, which rests on the conductive surface under pretension after the fastening pin has been interlocked.

Finally, in a further embodiment; for the formation of a defined contact zone on the conductive surface, aas
free end of the contact member a vault, such as 2.3. a bag
or to attach a recess.

You! Price increases and theirs. 3- £ For details, refer to the drawing · for
two exemplary embodiments explained in more detail.

Fig. 1 shows in a perspective bar position a part of a
Laminated resistor board with a solder connection for a printed circuit.

FIG. 2 shows a side view of a solder connection with pivot pins.

In the F ^ g. 1 is on the filing piece (1) of a non-resistance plate a lextsilver surface (2) applied for a variable resistance, which in turn with the not shown. Resistance School is in a leading position. The solder joint "faestehi; from the actual Soldering lug (3), the flat middle part (4) * the fastening pen (5f5 ') ^ tnd the contact arm (6).

In addition to fastening the solder connection, the originally stretched Fixing clamps bent so that they the pin (7) of the plate enclose tightly and the middle part (4) lies snugly on the plate. The arching (δ) of the presented contact arm (6) is pressed onto the conductive silver surface (2) with pretension a secure connection between this and the dip soldering lug (3).

In the second example (FIG. 2) there is also a section (1) of the sheet resistor plate shown, on which the conductive silver surface (2) is applied. The solder connection consists of the soldering lug (3), the Middle part (4) * the contact arm (6) and a cabinet pivot (9) »softer is inserted into a rectangular recess (1O) in the plate. By Turning the protruding end of the pivot pin becomes the Eötansohluß attached to the plate. Here, too, the cloudiness Exercise (δ) of the contact arm (6) with bias on the conductive silver surface (2) and forms a secure contact between this and the soldering lug (3).
