Bushing clamp body

To reduce the width of the clamp body to the dimension necessary for the clamp screw nut thread, »is on possible to cut the thread into the side walls of a clamp body. But then the gate part goes lost a clamp body bent from elastic sheet metal, which consists in the fact that it is braced by its tension the clamping screw secures against loosening. A thinning of the wall thickness at that of the clamping screw Making the side walls of the clamping body requires a special material mix in addition to the punching and bending process ebungs work process that makes production more expensive.

The narrowest version of a Buehsenklemmkörpers created from elastic sheet metal in that the lower flap with one or several approaches reduced in cross-section in the longitudinal direction in one or more recesses aes to the upper lobe belonging U-seinkel engages and that in both IT-legs Recesses in the area of the clamping tube or Clamping screws are provided.

Zuin compensate for by the recesses in the U-legs as occurring at large elasticity of the clamp body can, of the lower flap to be arranged at a downward angle approaches and on the side walls of the clamping body transversely to its longitudinal direction lying indentations to the "both end sides'.

The subject of the innovation is explained with reference to the drawing of exemplary embodiments of a tension yoke clamping body.

Fig. 1 shows this in side view,

Fig. 2 the front view,

Fig. 5 the angled stamped part and

Fig. 4 to β the corresponding views of a modification of this clamping body.

On a busbar 1 or 1 'is the tension bracket 2 or 2' with its clamping screw 3 t »zw. 3 * attached loosely. When the clamping screw is turned back, the conductor end 4 or 4 'is pushed into the space between the bottom of the clamping body and the busbar 1 or 1'. By tightening the clamping screw 3 or 3 ', the conductor end 4 or 4 ^f from the bottom of the clamping body 2 or 2 ^f , which moves upwards, is pressed against the busbar and with it

electrically connected. The busbar can be part of a Device or a clamp and leads, for example, to a second, identical tension bracket in the case of through-access clamps, in which a second conductor is clamped for the purpose of electrical connection with the first.

Especially in the case of terminal blocks made of insulating material, all Possibilities were considered to build the clamp and thus also the clamp body as narrow as possible. At a Screw terminal, the theoretical limit is given by the size of the nut piece required for the thread.

In both exemplary embodiments, this theoretical limit is reached in that the lower tab 5 or 5 ^! with a shoulder β or 6 'engages in a recess 7 or 7' of the U-leg 8 or 8 ^f belonging to the upper lobe and at the same time recesses 9? 10 or 9% 10 'are provided in both U-legs. As can be seen from Fig. And 5, the clamping body is as wide as' the lower lobe 5 or 5 '· Its smallest possible width is determined by the nut thread cutting into it for the clamping screw 3 or 3'. However, this dimension is such that the thread of the vision hood would engage in the side walls of the clamping body. To avoid this, the recesses 9> 10 or 9'j 10 'are provided.

From the two views Fig. 1 and 2 or, 4 and 5 it can be seen that the clamping screw is now can move freely.

The tension yoke clamps shown are intended for installation in modular housing made of insulating material. You have an angled tab 11 or 11 ^f on the floor. This serves, which cannot be seen in the drawing, to prevent the incorrect insertion of a conductor under the base of the clamping body.

Depending on the material used for the socket clamping body, the recesses according to the invention 9, 10 or 9'j 10 'and the G-threaded hole in the narrow lower tab 5 or 5 ^! Deformations occur or the bracket has too great elasticity when the conductor is clamped, so that the screw locking, the characteristic of the Illemmkörpers bent from elastic sheet metal with the clamping screw or clamping screws guided in overlapped U-legs, is not sufficiently available. For this pail are arranged on the side walls of the clamping body parallel to the recesses 9'j 10 ', impressions 12 and on the two sides of the lower tab downwardly angled attachments 13, 14 or flanging for stiffening.
