Problems solved by technology

However, in such a position, a secure connection is not guaranteed and the sealing effect is lost
When the bellows is bent or bent relative to the coupling part, the sleeve can be skewed on one side in the coupling part, which additionally reduces the tightness, but sometimes also leads to loosening of the connection. open or unplug
These defects are especially disadvantageous in those connections which are affected by water jets and can lead to malfunctions and damage

Embodiment Construction

[0020] figure 1 The coupling piece 1 is shown together with the inserted end 6 of the bellows 2 . The upper half of the figure is shown here as a section. The coupling part 1 comprises a housing 3 with a core cavity 4 . The housing 3 has an insertion opening 5 at one end, toward which the core cavity 4 is also open. At the opposite end of the housing 3 there is provided a connecting piece 8 with a passage opening 9 and a connecting flange 7 . In the exemplary embodiment shown, the connecting piece 8 is designed as a screw connection. However, it can also have another shape known for the coupling part described, for example it can also be a coupling element for the connection to the second bellows. In the core cavity 4 of the housing 3 there is a sleeve 12 which surrounds the end 6 of the bellows 2 . The housing 3 has a completely closed sheath without radial breaks. In the exemplary embodiment shown, both the housing 3 and the sleeve 2 are injection-molded parts made of ...

Abstract

The connection and joint piece (1) comprises a housing (3) and a sleeve (12), made from a multi-piece injection moulded plastic part. The sleeve (12) comprises an outer piece (14), forming an outer seal and an inner piece (15), forming an inner seal and a region with spring tongues (24, 25) and locking tabs (26, 27). The sleeve (12) is a multi-component injection moulded piece. In the assembled state the sleeve (12) is located in the central cavity (4) of the connector piece (1) and encloses one end (6) of a well tube (2).

Description

technical field [0001] The invention relates to a connecting and coupling piece for bellows, which has a housing with a core cavity and insertion openings for receiving the ends of the bellows, connecting flanges and a through-opening and a sleeve disposed between the outer sleeve at the end of the bellows and the inner sleeve of the core cavity of the housing, the sleeve has an elastic sheath segment and an inwardly and outwardly oriented Locking tabs. Background technique [0002] Corrugated pipes or corrugated hoses are flexible elements which are used, for example, in the construction industry when laying and protecting electrical and optical conductors or when connecting machines or other devices. A particularly common field of application is the use as flexible protective and guide tubes in the automotive industry. Bellows are mostly made of plastic, but can also be made of metal. In order to connect corrugated pipes to one another and to connect them to installatio...
