Abstract

The invention relates to a method for producing a plug-in connector, and to a plug-in connector comprising a first tubular component and a second tubular component, and also a first connection geometry and a second connection geometry. A method for producing a plug-in connector is to be made available that permits an easier modification of the relative angle between the longitudinal axes of the two components in the finished plug-in connector. To this end, the two connection geometries are arranged in a connection plane inclined with respect to the longitudinal axes, such that the relative angle between the longitudinal axes can be modified by rotating the components. After a relative angle has been selected, the two connection geometries are connected by integral bonding.

First claim

It is claimed:

1. A method for producing a plug-in connector, which plug-in connector comprises a first tubular component and a second tubular component, and also a first connection geometry and a second connection geometry, wherein the first connection geometry is arranged in a first connection plane, and wherein the second connection geometry is arranged in the first connection plane, and wherein the first connection plane is inclined with respect to a first longitudinal axis of the first tubular component, and wherein the first connection plane is inclined with respect to a second longitudinal axis of the second tubular component, and wherein a relative angle between the first longitudinal axis and the second longitudinal axis can be modified by rotating the first component with respect to the second component, said method comprising:
selecting a relative angle between the first longitudinal axis and the second longitudinal axis by rotating the first component with respect to the second component;
inserting a wedge-shaped connection projection of the second connection geometry into a circumferential, wedge-shaped recess of the first connection geometry; and
integrally bonding the first connection geometry to the second connection geometry at the selected relative angle.

2. The method according to claim 1 , characterized in that the first connection geometry is arranged in an intermediate component which is rotatable with respect to the first tubular component and/or the second tubular component before the integral bonding of the first connection geometry to the second connection geometry.

3. The method according to claim 1 , characterized in that the plug-in connector comprises a third connection geometry and a fourth connection geometry, wherein the third connection geometry and the fourth connection geometry are arranged in a second connection plane.

4. The method according to claim 3 , characterized in that the second connection plane extends parallel to the first connection plane, independently of the relative angle between the first longitudinal axis and the second longitudinal axis.

5. The method according to claim 3 , characterized in that, after the relative angle between the first longitudinal axis and the second longitudinal axis has been selected, the third connection geometry is integrally bonded to the fourth connection geometry.

6. The method according to claim 1 , characterized in that at least one integrally bonded connection is obtained by one of friction welding, ultrasonic welding hot gas welding, and laser welding.

7. The method according to claim 1 , characterized in that the plug-in connector has at least one projection arranged on an outer side of the plug-in connector, wherein the at least one projection extends perpendicularly with respect to the first connection plane.
