Patent ID: 11426948

Abstract:
The invention relates to a method and to an apparatus for producing a plug-through connection arrangement of a plurality of electrical cables (1a-1d) and/or fluid-conducting hoses, having a sheathing (2) consisting of a plastic, which extend, arranged adjacently spaced apart from each other, through associated openings (3a-3d) of a plastic component (4), comprising the following steps: providing (A) the plastic part (4) with the pre-produced plurality of openings (3a-3d), installing (B) the electrical cables (1a-1d) and/or fluid-conducting hoses through the associated openings (3a-3d), such that the outer wall of the sheathing (2), which consists of plastic, comes into contact with the inner wall of the respective openings (3a-3d) of the plastic component (4), thermal welding (C) of the electrical cables (1a-1d) and/or fluid-conducting hoses to the plastic component (4) in the region of the respective opening (3a-3d), in order to produce an integrally sealing component bond, wherein at least two laser beam units (5a, 5b), positioned opposite each other, are aligned to an associated initial connection point, after which the oppositely positioned laser beam units (5a, 5b) are activated and caused to undergo a linear relative movement crosswise to the orientation of the openings (3a-3d), in order to create the integral bond by surface melting of the sheathing (2) together with the plastic component (4).
