Solderless terminals to DIN 46234: for control cabinets, etc.

Even solderless terminals to DIN 46234 have to meet the requirements of the standard in terms of application, dimensions and marking. Solderless terminals are used for crimping with multi, fine and superfine stranded conductors. However, solderless terminals to DIN 46234 are not suitable for single-stranded solid conductors - unlike compression cable lugs to DIN 46235.

 

The conductor cross-sections of solderless terminals to DIN range from 0.5 mm² to 240 mm², the bore diameter for the connecting bolt from M2 to M16. Solderless terminals are used, for example, in control cabinet construction or in the construction of rail vehicles.

 

Just like compression and tubular cable lugs, solderless terminals essentially consist of electrolytic copper. For production, however, a different source material is used: while compression cable lugs are manufactured from tubes, solderless terminals are made from copper sheets. So by virtue of their design, rounded and soldered from a metal sheet, they have a distinctive soldered joint.

 

The quality of the soldered joint is key to the crimp result. Poor-quality soldered joints carry the risk of opening during the crimping process. Unlike the compression cable lug to DIN 46235, solderless terminals are not processed by hexagonal crimping, but instead by indent crimping. Klauke offers various tools for this purpose. The recommended tools can be found in the catalogue at the end of each chapter.
