Abstract
A technique for improving the retention force between a connector (10, 11, 12, 13, 14, 15, 16, 17, 100, 101) and a spacer (1) for insulating glass units is disclosed.

Connector for a spacer for insulating glass units, the spacer (1) extending in a longitudinal direction (z) with a constant cross-section in a cutting plane (x-y) perpendicular to the longitudinal direction (z) such that the spacer (1) encloses an interior cavity (1h), and being formed of plastic at least on the inner side enclosing the interior cavity (1h), comprising
- a first connector section (A1) adapted to be inserted into the interior cavity (1h) of the spacer (1) along the longitudinal direction (z), and
- a second connector section (A2) adapted to be inserted into the interior cavity (1h) of the spacer (1) along the longitudinal direction (z),
- wherein the first connector section (A1) and the second connector section (A2) are successively disposed along a center axis (R) extending in the longitudinal direction (z), and the first connector section (A1) is adapted to be held in the spacer (1) by contact with the inner side of the spacer (1) enclosing the interior cavity (1h) after insertion,
- characterized in that
- the first connector section (A1) includes two sub-sections (20, 21;
- 23, 24;
- 26, 27;
- 171, 172) having a toothing on their outer side and being moveable relative to each other and adapted to receive an external force in an inserted state, in which the first section (A1) has been inserted into the interior cavity (1h) such that at least a portion of the toothing is moved away from a plane which includes the center axis (R) by a corresponding relative motion.

- a first connector section (A1) adapted to be inserted into the interior cavity (1a) of the spacer (1) along the longitudinal direction (z), and
- a second connector section (A2) adapted to be inserted into the interior cavity (1h) of the spacer (1) along the longitudinal direction (z),
- wherein the first connector section (A1) and the second connector section (A2) are successively disposed along a center axis (R) extending in the longitudinal direction (z), and the first connector section (A1) is adapted to be held in the spacer (1h) by contact with the inner side of the spacer (1) enclosing the interior cavity (1h) after insertion,
- characterized in that
- the first connector section (A1) includes two opposite outer walls (126, 127) made of metal, each including a pre-embossing for forming a toothing (126z, 127z) by applying pressure from the inner side of the respective outer wall (126, 127) away from the center axis (R) toward the outer side to form an expansion toothing in an inserted state, in which the first section (A1) has been inserted into the interior cavity (1h).
