Abstract
A press-in nut is formed as a cap nut and has a nut body with a through hole, which is closed by a cap under formation of a blind hole. This is provided to obtain a media-tight connection with the nut body. The nut body has a ring collar at the top. In a pre-assembled state, the ring collar is only at least partially bent over, so that the cap is only held captively, without a media-tight connection being formed. The desired media-tight connection is only formed when press-fitting into a component.
Claims15
A press-in nut that which extends in an axial direction and is formed as a cap nut and for press-fitting into a component, the press-in nut comprising:
- a nut body with a through hole, which is closed by a cap under formation of a blind hole, wherein the nut body has a bottom for support on the component, and wherein on the bottom ribs are formed for anti-twist protection;
- and
- a ring collar arranged on a top of the nut body, wherein the ring collar is bent only at discrete points so as to form retaining lugs,
- wherein, in a pre-assembled state, the ring collar is only partially bent so that the cap on the nut body is only held captively.
A method for producing a press-in nut, the method comprising:
- providing the press-in nut with a nut body with a through hole and a ring collar surrounding it, and a cap for placement on the nut body, which is provided for media-tight closure of the through hole;
- and
- placing the cap on the nut body and then, in a first process step for forming a pre-assembled state of the press-in nut, the ring collar is only partially bent over so that the cap is only held captively on the nut body.
A method for producing a press-in connection, in which a pre-assembled press-in nut is pressed into a component, the pre-assembled press-in nut extending in an axial direction and is formed as a cap nut and has a nut body with a through hole, which is closed by a cap under formation of a blind hole, the method comprising:
- providing the nut body with a ring collar at a top;
- only partially bending over the ring collar in the pre-assembled state of the press-in nut so that the cap is only held captively on the nut body;
- and
- pressing, completely circumferentially against the cap, the ring collar with the aid of a press-in die for pressing in this pre-assembled press-in nut.
