Definitions

• the invention relates to a method and a device produced by this method for longitudinally watertight encapsulation of metal parts, in particular stamped gratings, according to the features of the respective preamble of the independent claims.
• stamped grid are encapsulated with a plastic in a known plastic injection molding process.
• the invention is therefore based on the object, a method for producing a metal part and a metal part, which is surrounded by an encapsulation of a plastic material partially provide in which measures are taken to the longitudinal water tightness in the axial extent of the metal in the area in which it is surrounded by the encapsulation to improve.
• the metal part in the course of its axial extent at least one embossing, preferably a plurality of embossments.
• This embossing or the multiple embossings can be circumferential depending on the geometric design of the metal part.
• the at least one embossing is formed once around the metal part, transversely to the longitudinal extent.
• it is provided in the case of a wire that it has at least one embossed groove or at least one peripheral bead as an embossing, this area being encapsulated with plastic over the entire area.
• a groove adjoins a bead or a plurality of grooves and a plurality of beads in the axial direction adjacent to each other.
• metal parts that have no round but another cross-section (for example, square, rectangular, triangular, oval or the like).
• the embossing in the form of a depression not by a forming without material removal, but by material removal, for example by milling, sawing, turning, grinding or the like to realize.
• a bead, survey or the like can also instead of a forming process without material removal by a material order (addition of material) on the metal part of the same or different material respectively.
• a material order additional of material
• this area and overlapping areas of the metal part are encapsulated in a plastic injection molding process known per se with plastic.
• a plastic material is used which contracts during and / or after the encapsulation, optionally with the addition of further process steps, in order to improve the contact of the overmolded region on the embossed regions and adjacent regions of the metal part .
• plastic materials into consideration either contract during the Umspritzvorgangs or exert a contraction after the actual Umspritzvorgang.
• materials may be conceivable which last or do not contract after the overmolding process, but contract with the aid of a further process step (such as reheating) to increase the bond between the metal part and the overmolded plastic to achieve the desired longitudinal water tightness.
• the at least one embossing in its course around the metal part has the same cross section and / or in its course around the metal part a changing cross section.
• the metal part is a stamped grid or cable of a connector and the encapsulation at least partially forms a housing of the connector.
• a component known per se namely a plug connector, in particular a plug connector for use in vehicle technology, can be further improved in this field with respect to the longitudinal water tightness.
• a stamped grid is arranged in a conventional manner within a connector, which forms on the one hand at least one contact partner, often several contact partners, in the direction of a mating connector. This punched grid is arranged at the end of a cable.
• a contact partner known per se such as a contact pin or a contact socket
• the metal part is this contact pin, this contact socket or the like, which has one or more embossments in the course of its axial extent.
• the electrical conductor, which is the metal part has at least one embossment. Such embossments can be very easily introduced, for example, in electrical conductors made of solid material or round material.
• the electrical conductor is a conductor made of stranded material
• it could, for example, be thought of rigidly forming it by means of solder in the area in which it is to be encapsulated with plastic and then introducing the at least one embossment in this area.
• the connection region between the electrical conductor and the contact partner is provided with the at least one embossing. This is for the sake of completeness supplement that this connection region, for example, a Krimp Scheme, is provided between the end of the electrical conductor and the contact partner targeted with the at least one embossing.
• the at least one embossment is aligned in a particularly preferred manner transverse to the axial orientation of the metal. In this case, the improved longitudinal water tightness is achieved particularly well.
• the left-hand illustration is the section of a stamped grid (once from above and once from the side), before this part of the stamped grid has been overmoulded with plastic.
• the punched grid which is rectangular in cross-section, has at least one embossment.
• four embossments in the form of grooves and adjacent protrusions of material are realized.
• the shape of the embossment can be freely selected, thereby ensuring that in the overmolded area and adjacent adjacent areas the surface, with which the encapsulation rests against the metal part, is markedly increased by the imprints in order to ensure the longitudinal water tightness and, if necessary, at the same time also to effect a strain relief.
• the metal part is shown in the right illustration after it has been surrounded with a plastic (hatched area, partial).
• a plastic hatchched area, partial
• the spray material settles on the surface of the metal part and of course also in the intermediate regions between the material overhangs, in order to realize the longitudinal water tightness.
• a plastic material is used, which optionally contracts during the injection process, but in any case after carrying out the injection process, so as to To significantly increase investment forces of the encapsulation on the surface of the metal part.
