Patent ID: 10745963

Abstract:
A plug connector (1) and a plug connection (2), for hollow profiled sections (3, 4) of spacers of an insulating glazing, has a base (8) with edge-side lateral walls (10), a central stop (21), and retaining elements (16). The plug connector (1) is formed of a temperature-resistant material, in particular metal, at least in the region of the connector center (20) and is suitable for a welding connection (5) of the hollow profiled sections (3, 4). The plug connector has a shape which is rigid against external transverse loads at least in the central region and a substantially U-shaped cross-section with a hammerhead shape and lateral walls (10), which are recessed in steps (11) in the upper region (12). The lateral walls (10) have a supporting and retaining structure (15), which is oriented towards the roof (27) of the hollow profiled sections (3, 4), at the upper free edge (14).
