Definitions

the invention relates to the optimum shaping of connecting elements [ Fig. 1 ], which are soldered by means of a solder paste [a] on a metallic substrate [b].
Such fasteners are usually designed as screw [c] or plug-in connections with screw connections, these are mainly loaded with a torque [d], in connectors, however, usually with a tilting moment [e].
the load capacity depends directly on the quality of the solder joint, ie on the adhesion of the connecting element on the substrate
soldering Another difficulty of soldering is that these connecting elements have a relatively large mass, therefore, the thermal energy expenditure for melting the solder paste is relatively high. If the solder joint is not supplied with sufficient thermal energy, so-called cold solder joints are formed which greatly reduce the adhesion of the connector to the substrate.
the aim of the present invention is to improve the adhesion and thus the mechanical strength of the soldered connection element in that the wettable surface is increased by appropriate shaping with the same base area and / or anchors are attached to the connecting element or on the substrate to the mechanical strength to increase.
a further object of the invention is to target the mass to be heated for the soldering with constant mechanical properties (eg by means of rejuvenation).
Figure 3 , g] in such a way that the thermal energy to be expended for the soldering can be reduced and nevertheless no cold solder joints are formed.
solderable surface is achieved by attaching vertical grooves [k] to the periphery of the connecting element associated with the soldering surface.
the molten solder rises [l] on the flanks of the grooves [k], [h] and on the walls of the bores, which additionally increases the effectively soldered surface and thus improves the adhesion of the connecting elements to the substrate [b] becomes.
anchors [m] which are wetted in the same soldering process by the solder paste [a1] causes the mechanical load capacity is further increased many times.
These anchorages [m] can be used both on the connecting element [ Fig. 5 ] as well as on the substrate [b] and extend into corresponding recesses of the substrate [o] and / or the connecting element itself.
