Terminal block for electrical cables

The invention relates to terminal blocks for electrical lines? from the outset on an approximately U-shaped Tragaehiens can be put on and are about egg-shaped, behind an angled stay of the! Clamp gripping springs releasably on these »With narrow clamp bodies serves as a locking device a single spring, while wider clamp bodies have two springs as a detent mechanism, which are preferably on two Fs at a distance from each other distributed on one side of the clamp body each in appropriate hats or »cutouts are arranged«,

As can be seen from FIGS. 3 and 4, In the foot 2 dee clamp body 1, whose Raateinrichtung only one Includes spring point for receiving the spring or springs a slot-shaped recess 3 is provided, which is so wide that it can accommodate two springs of the same wire size. This slot-shaped recess can 'naturally wider or narrower, sain, we-, more or less feathers should be accommodated in it ο Of course, with large clamp bodies, their Latching device several over the length of the iC clamp body comprises spring points distributed at intervals, several such slot-shaped recesses can be provided. » the both springs 4 and 5 are inserted into the slot 3 so that the opening of one spring is at the top and that of the other Spring is at the bottom · Daduroh results in a gradation under the assumption made above the lifting spring force to 1 i / 3p compared to 2p in the case » in which the opening of both springs would be at the top. The side walls of the slot-shaped recess 3 are in their - rear part set down on the outside »so that the rear Both springs 4 and 5 protrude laterally and behind the shoulder of the side walls of the slot you can "grip" these springs in slot a safe Halt cu »The paragraphs in the side walls of the

The embodiment of the erfindungsgeiaässen terminal shown in Figo 5 and 6 corresponds to the whole of the "in Fig. 3 and 4 Here, too, however, the clamp body 11 is provided a slit-shaped recess 13 for receiving two locking springs H ₉ 15 in the foot 12, in the present case are designed in the manner shown in FIG. Again, one spring 14 is inserted into the slot in such a way that its opening is at the top, while the opening of the other spring 15 is at the bottom, whereby the gradation of the fader force already described is achieved. To give the springs 14 and 15 a secure hold in the Schiita 13, the upper and lower walls of the slot are offset in their rear part upwards or downwards, so that the approximately radially outwardly resilient rear end of the springs to the insertion of which jumps into the slot 13 behind the shoulder formed.Up to the shoulders in the upper or lower slot wall are again formed by a shaft 16, which in the present case ends at the level of one side wall of the slot and is approximately trapezoidal in cross-section so that it protruded from the front part of the slot upwards and downwards by an amount corresponding approximately to the size of the wire

Finally, Fig. 7 shows several clerical bodies of different sizes sitting on a mounting rail 20 in perspective 22 is provided for large conductor cross-sections. One therefore has only one locking device with a spring point and a spring, while the other 22 has a locking device with two spaced peder points each with a spring. Between these two terminal bodies 21 and 22 is a terminal body. 23 arranged, which like the body 21 has only one spring point, but is provided for larger conductor cross-sections, as can be seen from the largerai; Dimensions of the body gives. Sa must therefore also be provided for a correspondingly firmer hold of the body on the mounting rail, which is why two springs are used at the single spring point of the body.

Of course you can also use a clamp body two or more spring points, such as the clip body 22 at each spring point with two or more flour. "Feathers off" equip, if necessary, with appropriate Arrangement of the springs at the individual spring points the desired gradation of the total spring force is achievable *
