Patented Oct. 5, 1937 PATENT OFFICE ELECTRICAL CONNECTING CAP Alfred Mendel, Berlin-Oharlottenlmrg,
and
Ernst Kleinmann, Berlin-Sohoneberg, Germany Application In Germany dclaims.
This invention relates to caps for making electrical connection such for example as those applied over the ends of small rod-like resistances of the kind now employed in wireless apparatus.
Such resistance 'caps are often provided with long soldering lugs stamped out of the same piece of metal as the caps proper. Such lugs are flat and as they are employed for effecting electrical connection between the resistance or the like and other components of the apparatus, it is desirable that they should be capable of being bent in all directions in accordance with the positions of the connecting wires so that connection may be effected easily. However, it is possible to bend an axis lying in its plane or nearly inits plane, but not about an axis lying well outside it. Thus, bending edgewise is not possible. It is therefore necessary to twist such a lug if the direction in which it is desired to bend it for connection purposes does not lie perpendicularly to the plane of the lug. However, not only does this involve an additional operation which increases the cost of production of the apparatus, in which often more than twelve resistances involving twenty-four connections are provided, but the lugs are stressed internally to such an extent that they may easily break. One of the objects of the present invention is to providea cap having a lug that can easily be bent in any desired direction. Another object is to form a cap with an easily bendable. lug from less metal than has been used hitherto in the manufacture of such caps. Yet another object is to provide a lug that can easily be bent and yet has a strong connection with the cap proper.
Our invention will most readily be understood by the following description of two caps constructed in accordance with it when read in conjunction with the accompanying drawing, in which Figure 1 shows a perspective view of the known i'ormoicaphavingaiiatlug;
Figure 2 shows an underneath view of the same cap after being further shaped in accordance with our invention;
Figure 3 shows a perspective view of the end of the lug of the cap shown in Figure 2: and
Figure 4, shows a perspective view of the second form of capaccording to our invention.
The-known form of cap shown in Figure 1 consists of a cap proper l and a flat strip of metal forming a lug 2 projecting out from the bottom or the cap and stamped from the same piece oi-metal as the can. Ac s our invention the lug 2 is bent for the major portion of its length about its longitudinal axis the flat lug of such a resistance cap only about- July 7, 1936, Serial No. 89,420
July 11, 1935 into the form of a wire. A flat portion 8 is left between the cap proper I and the wire shaped part, which is numbered I 'in Figure 2. The actual shape into which the wire shaped part 4 is bent is shown clearly by Figure 3. The lug I can easily be bent in any direction and owing to the provision of the flat part 3 the risk of the lug breaking or tearing away from the cap during the bending is very small.
Referring now to Figure 4, the lug is made in the same way but the bottom of the cap is stamped out so that the cap proper takes the form of a ring 5.
This afl'ords the advantages first that metal is saved and secondly that when the cap is applied to a resistance or carbon rod the lug projects out .from the end of the rod and not from a point displaced from the end of the rod by the thickness .of the cap. Accordingly it is possible by bending the lug only twice at right angles to bring it into the longitudinal axis of the resistance or the like. Such a metal ring will grip the end of the resistance or the like just as firmly as a cup-shaped cap.
We claim:
1. An electrical connector comprising a sheet metal stamping adapted to make contact in an electrical circuit and an integral soldering lug composed of a flat strip of metal shaped into the form oi a flexible wire and bendable in any direction for at least the major portion of its length.
2. An electrical connecting cap comprising a cup-shaped sheet metal stamping adapted to fit tightly over the end of a resistance or the like and an integral soldering lug composed of a flat strip of metal bent into the form of a-flexible wire for at least the major portion of its length and bendable in any direction.
3. An electrical connecting cap comprising an annular sheet metal band adapted to fit tightly over the end of a resistance or the like and an integral soldering lug composed of a flat strip of metal bent into the form of a flexible wire bendable in any direction for at least the major portion of its length.
4. An electrical connecting cap comprising an annular sheet metal band adapted to fit tightly over the end of a resistance or the like and an integral soldering lug projecting out from one edge of said band and bent for at least the major portion of its length about its longitudinal axis into the form of a flexible wire adapted to be bent in any direction.
