Problems solved by technology

The problem here is that the clamp operates while the first step is being performed, triggering the second step early even though the first step is not over yet
Then there is the disadvantage that reliable assembly may not be guaranteed or the assembly costs are rather high

Embodiment Construction

[0018] figure 1 The plug-in connector and mating part according to the first embodiment are shown schematically during assembly. The plug-in connector 1 has a longitudinal axis 3 , with which a bore 4 of the mating part 2 is matched when the plug-in connector 1 is inserted into the mating part 2 . The plug-in connector 1 is here inserted into the bore 4 along the longitudinal axis 3 in the insertion direction 5 . The insertion is achieved in multiple steps, as follows according to Figures 1 to 3 Be explained.

[0019] figure 1 The illustrated plug connector 1 has a plug socket 6 . An axial bore 7 is formed in the plug seat 6 through which the medium passes, for example from the end 8 of the bore 7 , into the bore 4 of the fitting part 2 in the assembled state. However, the medium can also reach the end 8 of the bore 7 from the bore 4 of the fitting part 2 . In this case, connecting channels for connecting pipes (not shown) are arranged at the end 8 , for example perpend...

Abstract

A plug connector (1) is used for lines (11) carrying media, in particular hydraulic lines of fuel injection systems. The plug connector (1) comprises a plug body (6), having a catch element (15), and a securing clip (18) movable relative to the plug body (6) into a locking position, the securing clip (18) securing the catch element (15) when in the locking position. Securing wings (20, 21) are also provided for the securing clip (18). When in a securing position, the securing wings (20, 21) protect the securing clip (18) against the displacement of said securing clip (18) into the locking position.

Description

technical field [0001] The invention relates to a plug connector for a medium-conducting line. In particular, the invention relates to the field of plug connectors for hydraulic lines of fuel injection systems. Background technique [0002] A plug connector for guiding medium lines is known from DE 10 2006 061 952 A1. The known plug-in connector is suitable for fastening in an opening of an injector body of a fuel injector. The plug connector has a plug socket on which at least one snap-in element is formed and which has at least one connecting tube. The catch element is fixed in the opening in a locked position of a clip movably received on the plug socket. [0003] In the case of the plug-in connector known from DE 10 2006 061 952 A1, the retaining clip is moved behind the snap-in element for fastening on the mating part after assembly of the plug socket. This prevents the snap-in element from springing back and thus releases the plug connector from the mating part dur...
