  • Patent number: 10527016
    Abstract: A plug connector for connecting to an electric connection of a fuel injector of an internal combustion engine can comprise a rail extending in a longitudinal direction and at least one insulating element arranged in a linearly movable manner in the longitudinal direction relative to the rail, wherein the at least one insulating element protrudes out of the rail in a transverse direction. In some embodiments, the at least one insulating element comprises means for electrically connecting to the electric connection of the fuel injector in an oil-tight and releasable manner on a side facing away from the rail in the transverse direction. In some embodiments, the rail comprises a guide extending in the longitudinal direction configured to guide the at least one insulating element relative to the rail in the longitudinal direction and hold the same in a formfitting manner in the transverse direction relative to the rail.

  • Patent number: 9956575
    Abstract: A holding device (1) holds a lens (6) at its lens edge (5) with the aid of an adhesive connection (16, 17). The adhesive connection (16, 17) is applied only at one adhesive point or only at two spaced apart adhesive points (16, 17). Each holding device (1) provided with a lens (6) is positioned on the dip frame in such a manner that the lens (6) is positioned above its holding device (1). A method is provided for finishing lenses (6) wherein the lenses (6) are subjected to various sequential finishing steps of a finishing process and the lenses (6) are cemented to the same holding device during finishing. The application of adhesive is only at one adhesive point or at two spaced apart adhesive points (16, 17).

  • Patent number: 8435065
    Abstract: A plug-in unit (112, FIG. 7A) with a housing (150) that receives an electrical contact arrangement (55, FIG. 6) that has a cable bushing (151, FIG. 7A). The housing has an aperture (153) in a housing wall for the plugged-in reception of the mating plug-in unit (11, FIG. 2). In order to allow for the optional design of an angled or a linear plug-in connection, the cuboid housing (150, FIG. 7A) is divided along a plane (180) that runs perpendicular to a longitudinal central plane (179) and at a 45° angle to the longitudinal extension of a bushing (151) in such a way that a first housing part (181) contains the cable bushing (151) and the second housing part (182) forms the plug-in aperture (153). The second housing part (182) is attached to the first housing part so the second housing part (182) can be turned with respect to the first housing part (181).
