Abstract

A plug-in connection (1) is provided for hollow profiled elements (2) of spacer holding frames for insulating glass panes. The plug-in connector (1) has at least one connector part (3, 4) including an essentially U-shaped or box-type cross-section, having lateral walls (15, 16), at least one central wall (14), and, on the connection point (8), a central abutment (18) with a plurality of elastic abutment elements (19, 20), on the edge region of the lateral walls (15, 16). The central abutment includes two mutually oriented individual abutment elements (19, 20) which are arranged on both sides of the connection point (8), each on a lateral wall (15, 16), and have a cushioning effect essentially in the plane of the associated lateral wall (15, 16) thereof. The lateral wall (15, 16) have a recess (26) beneath the abutment element (19, 20).

Claims19

Dependent claims

A plug-in connector for hollow sections of spacer frames for insulating glass panes, the plug-in connector comprising:

a connector part comprising:
an essentially U-shaped or box-shaped cross section with side walls and at least one middle wall;
and
a center stop comprising a plurality of elastic stop elements at a connection point at the edge area of the side walls, wherein the center stop has two separate stop elements directed opposite each other, said two separate stop elements being arranged on both sides of the connection point with only one of said stop elements at one of said side walls and with only one of said stop elements at another of said side walls and with said stop elements each being essentially elastic in the plane of said one of said side walls and said another of said side walls, respectively, to elastically move transversely to a lengthwise extension with respect to the adjacent side wall wherein each of the stop elements has a head part which is wedge-shaped and widens towards the connection point and the head part has a constriction on a rear side, wherein each of the stop elements has an elastic stop inner edge angled toward an outer side of the associated wall, from a stop end toward the constriction, and with an elastic stop outer edge angled away from the outer side of the associated wall, from the stop end toward the constriction.

A plug-in connector for hollow sections of spacer frames for insulating glass panes, the plug-in connector including a connector part comprising:

an essentially U-shaped or box-shaped cross section with a first side wall with a first wall recess and with a second side wall with a second wall recess and with at least one middle wall;
and
a center stop comprising two separate elastic stop elements including a first elastic stop element having a first cantilever extent, extending from the first side wall in a first direction and having a first elastic stop inner edge along the first wall recess and having a first elastic stop outer edge at an opposite outer side and a second elastic stop element having a second cantilever extent, extending from the second side wall in a second direction and having a second elastic stop inner edge along the second side wall recess and having a second elastic stop outer edge at an opposite outer side, the first direction being directed opposite to the second direction, said first elastic stop element being arranged on a first side of a connection point with said second elastic stop element arranged on a second side of the connection point, said two separate elastic stop elements being essentially elastic in a plane of an associated side wall wherein said first elastic stop element has a wedge-shape that widens towards the connection point from a first stop constriction inwardly of the connection point and with the first elastic stop inner edge angled toward the opposite outer side of the first wall, from the connection point toward the first stop constriction, and with the first elastic stop outer edge angled toward the first wall recess, from the connection point toward the first stop constriction, and wherein said second elastic stop element has a wedge-shape that widens towards the connection point from a second stop constriction inwardly of the connection point and with the second elastic stop inner edge angled toward the opposite outer side of the second wall, from the connection point toward the second stop constriction, and with the second elastic stop outer edge angled toward the second wall recess, from the connection point toward the second stop constriction.

A plug-in connector for hollow sections of spacer frames for insulating glass panes, the plug-in connector including a connector part comprising:

an essentially U-shaped or box-shaped cross section with a first side wall with a first wall recess and with a second side wall with a second wall recess and with at least one middle wall connecting the first side wall to the second side wall;
a first elastic stop element defined by a first cantilever extent extending from the first side wall in a first direction as an only first side wall stop element, said first elastic stop element comprising a first elastic stop inner edge along the first wall recess and comprising a first elastic outer edge at an opposite outer side, said first elastic stop element having a first stop head part with a wedge-shape that widens towards a first stop end, from a first stop constriction inwardly of the first stop end, and with the first elastic stop inner edge angled toward the opposite outer side of the first wall, from the first stop end toward the first stop constriction, and with the first elastic stop outer edge angled toward the first wall recess, from the first stop end toward the first stop constriction;
a second elastic stop element defined by a second cantilever extent extending from the second side wall in a second direction as an only second side wall stop element, the second elastic stop element comprising a second elastic stop inner edge along the second side wall recess and comprising a second elastic stop outer edge at an opposite outer side, said second elastic stop element having a second stop head part with a wedge-shape that widens towards a second stop end, from a second stop constriction inwardly of the connection point, and with the second elastic stop inner edge angled toward the opposite outer side of the second wall, from the second stop end toward the second stop constriction, and with the second elastic stop outer edge angled toward the second wall recess, from the second stop end toward the first stop constriction, wherein:
the first direction is directed opposite to the second direction;
the first elastic stop element is arranged on a first side of the connection point;
said second elastic stop element is arranged on a second side of the connection point;
and
said two separate elastic stop elements are essentially elastic in a plane of an associated side wall and together form a center stop.
