Plug with an over-molded, non-rotatable plug connector and four connectors, in particular an is4/df4 plug

Abstract

A method for producing a plug, and to a plug. It is provided, in particular, that a plug connector and three plug contact rings are arranged in a casting mold, wherein the plug connector extends along a longitudinal axis and has a contact portion and a fastening portion connected integrally to the contact portion, and wherein a plug housing is formed by introducing a casting material into the casting mold so that the fastening portion is surrounded form-fittingly by the casting material and the contact portion protrudes out from the plug housing at a first end of the plug housing in the direction of the longitudinal axis.

1 - 15 . (canceled) 
     
     
         16 . A plug, comprising:
 a plug housing, which extends along a longitudinal axis,   a plug connector extending along the longitudinal axis and which comprises a contact portion and a fastening portion connected integrally to the contact portion, wherein the fastening portion is cast form-fittingly in the plug housing so that the fastening portion is surrounded form-fittingly by a casting material and the contact portion protrudes out from the plug housing at a first end of the plug housing in the direction of the longitudinal axis, and   three plug contact rings arranged coaxially with respect to the longitudinal axis, wherein the plug contact rings each have an outer side, and wherein the plug contact rings are cast in the plug housing so that the outer sides of the plug contact rings are each arranged in an exposed manner on an outer side of the plug housing and are electrically contactable.   
     
     
         17 . The plug according to  claim 16 , wherein end portion of each conductor extends in the direction of the longitudinal axis, and wherein the second end portions are each arranged at the same distance from the longitudinal axis in a radial direction running perpendicularly to the axial direction. 
     
     
         18 . The plug according to  claim 16 , wherein the plug housing surrounds an inner lumen, wherein the inner lumen is fluidically connected to a lumen of the plug connector, where in the lumen of the plug connector is aligned with the inner lumen. 
     
     
         19 . The plug according to  claim 16 , wherein the plug housing has a protrusion formed at the second end of the plug housing, which protrusion surrounds an end portion of the inner lumen. 
     
     
         20 . The plug according to  claim 16 , wherein the plug housing has coding for distinguishing between the conductors. 
     
     
         21 . The plug according to  claim 16 , wherein the casting material is one of the following materials: PEEK or another plastic, wherein the particular plastic material has a hardness that is greater than 75 Shore D. 
     
     
         22 . The plug according to  claim 16 , wherein the fastening portion of the plug connector and the plug contact rings are electrically conductively connected to a first end portion of an electrical conductor each, wherein each conductor is cast in the plug housing and protrudes out from the plug housing at a second end of the plug housing via a second end portion, wherein the second end portion of each conductor forms a contact for electrically contacting the corresponding conductor. 
     
     
         23 . The plug according to  claim 22 , wherein the electrical conductor connected to the fastening portion of the plug connector is cast together with the fastening portion form-fittingly in the plug housing so that the plug connector is fixed in the plug housing non-rotatably with respect to a rotation about the longitudinal axis.
