  • Patent number: 10066516
    Abstract: The invention relates to a bucket tappet for an internal combustion engine, having a tappet housing with a hollow cylindrical bucket skirt and a bucket base which closes one side of the bucket skirt and on which the bucket skirt is formed by cold forming a steel blank without cutting. The outside of the bucket base is used as a contact surface for an internal combustion engine cam which transfer a stroke movement to the bucket tappet, and the outside of the bucket skirt is used as a contact surface for an internal combustion engine guide bore which supports the bucket tappet in the stroke direction. The aim of the invention is to develop a bucket tappet of the aforementioned type and a method for producing same with respect to reduced production costs. This is achieved in that the unmachined and uncoated cam contact surface of the bucket base is machined using a brushing tool and no additional mechanical machining of the cam contact surface is carried out.

  • Patent number: 7033211
    Abstract: An electrical angular pin-and-socket connector (1) is provided which includes two individual, separate angle legs (2) and (5). The second angle leg (5) includes a receiving opening (8) which opens perpendicularly to the profile of the angle leg, and in which a plug-in section (9) of the first angle leg (2) can be plugged and fitted, the two angle legs (2) and (5) being intermated in a functional position. In order to mutually lock the two angle legs in the functional position, an opening (10) extending perpendicularly to the axial extension of the first angle leg (2) is created through the second angle leg (5), in the cover or contact region inside the receiving opening (8), and part of the cross-section of the opening is respectively present in the contact region of the two angle legs, in such a way that a fixing screw (6) passing through the opening (10) or borehole positively grips the two angle legs and mutually locks the same.

  • Patent number: 6935886
    Abstract: A plug connector has, in a housing, an insulating member, which in a known manner receives contact elements, for example, contact pins and/or contact sockets, which are connected to individual wires or strands of an electrical cable. The plug connector also includes a clamping member or clamping insert in order to also fix the electrical cable relative to the housing, which takes place by a clamping nut, preferably by a union nut. In order to easily assemble these parts and to maintain a given spacing in the axial direction, the insulating member and the clamping member are connected by at least one, and preferably a plurality of spacers, with a radially open interspace remaining free laterally of the spacers, and between insulating member and clamping member. The insulating member and the clamping member are preferably separate parts, which can be reciprocally connected by the spacers.
