A method is provided for rotationally attaching a connection fitting with an opposing surface by screwing the fitting into the opposing surface by threads on an outer surface of the fitting body. The connection fitting is formed by at least one seal manufactured together with the fitting body in an injection molding process to form a multi-component plastic part in which the fitting body is made of a hard plastic component and the seal is made of a soft plastic component, wherein the components are of a kind which do not adhere to one another. The seal is secured in an axial direction on the fitting body in a form-fit manner, but during the rotational attachment step the seal is rotatable relative to the fitting body in a peripheral direction.

Method for rotational attachment of a connection fitting to an opposing surface

A connection fitting ( ) for the attachment of oblong structures, for example of cables ( ), hoses, tubes, corrugated hoses or the like, to an opening ( ), in particular, for passing through such an opening ( ) while at the same time being attached is provided. The opening ( ) involves a hole, a drill hole, or other opening in a wall ( ), for example of a housing. The connection fitting ( ) is constructed as a plug-in fitting, i.e. is readily affixed to the opening ( ) by axial insertion into it. For this it has an attachment projection ( ) which is subdivided by axial slits into retaining tongues, which have radially projecting retaining projections ( ) on the outside that extend behind the edge ( ) of the opening ( ) when the attachment projection ( ) is inserted into the opening ( ), such that they yield somewhat radially to the inside during insertion and after being stuck through, automatically move again radially outwardly. By an axial movement of the connection fitting ( ) opposite its plug-in direction, the retaining tongues ( ) can in turn be deformed in the radial direction against the oblong structure or a cable ( ) that is to be affixed and then clamped onto it. Thus, on the outside of the opening ( ), a stopper ( ) is provided so that the connection fitting ( ) is supported on the outside. The sheath that has the stopper ( ) has a support ( ), which extends axially into the opening ( ) and which in the assembly position engages on a partial area of the outside of the retaining tongues ( ) of the attachment projection ( ), and during an axial movement of the attachment projection ( ) and the retaining tongues ( ), impinges a conical or tapering area of the outside of the retaining tongues ( ) in such a way that the retaining tongues ( ) are pressed together in the radial direction so that a contact of the retaining tongues ( ) with the edge ( ) that is engaged behind is avoided or if necessary done with a considerably less force than is applied for a radial deformation of the retaining tongues ( ).

A mounting ( ) designed for oblong structures such as cables ( ), hoses or the like, which have an electrical shielding sheath ( ), that contains in the usage position of an electrically conducting insert ( ) that has a clamping finger ( ) and creates an electrical connection between the shielding sheath ( ) and the mounting ( ) is provided. The mounting ( ), under certain circumstances merely a wall opening or the like, possibly however also a complete cable screw connection with strain relief for the oblong structure&mdash;has a receptacle opening ( ) for the insertion and guiding through of the oblong structure or cable ( ) and especially also for the reception of the electrically conducting insert ( ), which for its part has a mounting ring ( ) and clamping fingers ( ) that project from it in the axial direction. On the outer side of the electrically conducting clamping fingers ( ) which function for the contact, a projection ( ) extends radially outwardly, at a distance from the free ends ( ) of the clamping fingers ( ), which function as a contact position, and at a distance from the mounting ring ( ) respectively. Through the projection ( ), the clamping fingers ( ) are bent or swung inwardly during the insertion into a correspondingly narrow receptacle opening ( ) by an amount corresponding to the dimension of these projections ( ) and the receptacle opening ( ), and thus make a secure contact on the oblong structure.

Mounting for oblong structures with an electrical shielding

An angle-shaped line entrance (,) has two branches (,) and (,) set at angles to each other and functions for the attachment to a wall (,) or a housing in the area of a corresponding hole-shaped opening. In this way, oblong structures, for example, hoses (,) or cables or the like, can be guided and affixed on or through the wall (,), such that the corresponding oblong structures enter into the first branch (,), while the second branch (,) itself is connected to the housing or its wall (,). In the angular area, the two branches (,) and (,) can be swung relative to each other, so that they can also take on an aligned position. Locking in the angular usage position is done by coupling via a movement for the attachment of the oblong structure at least in the first branch (,), in such a way that both movements can be performed with the same activation component.
