Definitions
- the invention relates to a cable lug with a connection area for
- the invention further relates to a contact element with such a cable lug and a method for producing such
- cable lugs are known from the prior art, with which a cable can be connected to a connecting part of an electrical system.
- the cable lug is typically connected to one end of a cable, in particular by welding, soldering or crimping
- connection area of the cable lug can then be connected with its contact part to a connection part, for example by a threaded bolt of the connection part being guided through the fastening recess and being secured with a nut, or by a screw being passed through the fastening recess and being screwed into a threaded bore of the connection part.
- Connection between a cable and a connection part of an electrical system are made.
- the cable lugs are generally provided with a housing in order to connect the cable lug to the cable and to the connecting part of the Protect electrical system from corrosion. Furthermore, such
- Such a contact element with a cable lug, a conductor connected to it and a housing is known for example from DE 10 2013 021 409 A1.
- the housing often consists of a plastic and can be produced, for example, by injection molding. Since when connecting the cable lug with a
- connection part of an electrical system especially when tightening a nut or screw, high mechanical loads can act on the cable lug, a secure embedding of the cable lug in the housing is desirable so that the cable lug cannot detach from the housing even when subjected to force and a permanent one Protection against penetrating moisture is guaranteed.
- the present invention has for its object a cable lug, a contact element with such a cable lug and a
- This task is carried out with a cable lug with a connection area
- the contact part Connecting the cable lug to an electrical conductor and to a contact part for contacting a connection part of an electrical system, in particular an electrical system of a motor vehicle, the contact part having a fastening recess for passing a fastening element through for fastening the cable lug to a connection part, according to the invention thereby solved, that the contact part has one or more further recesses.
- the one or more further recesses allow a better connection of the cable lug to a housing injected around the cable lug by one or several of the one or more further recesses are injected with the material of the housing during the encapsulation of the cable lug, so that the material of the housing runs through the one or more further recesses.
- the cable lug is positively embedded in the molded housing in the recess.
- a part of the contact part with the fastening recess and thus in particular the fastening recess itself remain free during the encapsulation in order to connect the cable lug to a connecting part by passing a fastening element through it
- the above-mentioned object is further achieved according to the invention by using the cable lug described above for producing a contact element in the injection molding process.
- the injection molding process in particular one or more of the one or more further recesses are injected, so that the contact part and thus the cable lug can be firmly embedded in the encapsulated housing. Since the plastic is not a material bond
- the electrical conductor can in particular be a cable, preferably with strands, for example copper strands or aluminum strands.
- the contact part of the cable lug is preferably flat in order to
- the cable lug preferably has a flat annular contact part with a
- Fastening recess in the form of a central bore in particular and several smaller recesses arranged around it.
- the fastening recess is in particular a central opening, for example a bore, in the contact part, through which a
- Fastening element in particular a screw or a threaded bolt
- the contact part can thus be designed in particular as a ring.
- the fastening recess can also be open to the edge of the contact part.
- the contact part can in particular also be designed as a fork.
- the one or more fastening recesses are preferably completely surrounded on the edge side by the material of the contact part, i.e. arranged at a distance from the edge of the contact part. In this way, a secure, form-fitting fixation of the cable lug is achieved in an overmolding.
- the recesses can for example be round, oval or elongated.
- connection area of the cable lug can be provided in particular for welding or soldering on an electrical conductor and, for this purpose, can be flat, for example.
- a metallic contact layer can be applied in the connection area, for example by friction coating, in order to improve the welding contact with an electrical conductor. Cable lugs with such a metallic contact layer are known for example from DE 10 2014 011 887 A1.
- the connection area can also be set up for a crimp connection, the connection area for this purpose preferably having crimp wings which are bent around the strands of the cable during crimping with a cable.
- a connection area designed for a crimp connection for crimping is preferably formed only on the conductor strands, ie without
- Insulation crimping Since the cable lug is provided for insert molding, there is typically no need for insulation crimping, which serves to stabilize the crimp connection, since the insert molding provides the necessary stability.
- the cable lug and an adjoining section of the electrical conductor are preferably extrusion-coated with an electrically insulating housing in such a way that part of the contact part with the fastening recess is exposed. In this way, in particular the connection area of the cable and cable lug is extrusion-coated and thus protected from moisture.
- Embodiments can be combined with each other.
- the one or more further recesses are at least in one direction smaller than the fastening recess. In this way, the contact parts can be made smaller and more space-saving, without the material missing due to the one or more further recesses leading to a weakening of the contact part. In another embodiment, the one or more others are
- Recesses arranged closer to the edge of the contact part than the fastening recess. As a result, the one or more further recesses can be injection-molded more easily when the cable lug is encapsulated, while the fastening recess is left free.
- the contact part has several more
- Recesses that are arranged around the mounting recess. In this way, a multi-sided fixation of the contact part can be achieved during the encapsulation, so that the contact part can better absorb forces in different directions.
- At least one of the one or more further recesses in the cable lug is injection molded with the material of the housing.
- at least one of the one or more further recesses of the cable lug is injected with the material of the housing during the manufacture of the housing. In this way, the housing is sprayed directly during the injection molding process to produce the housing, in order to ensure that the cable lug is securely anchored in the housing. A separate spraying process for spraying through the at least one further recess is therefore unnecessary.
- the hardest possible material is typically used for the housing, which enables the cable lug to be anchored particularly strongly in the housing.
- the material of the housing is preferably a
- thermoplastic elastomer in particular a thermoplastic polyurethane, more preferably with a hardness of at least Shore-D 60.
- Shore hardness is understood to be the Shore hardness, measured in accordance with DIN 53505EN.
- the contact element has an element molded onto the housing and at least one of the one or more further elements Recesses in the cable lug are sprayed with the material of the molded element.
- at least one of the one or more further recesses of the cable lug remains free during the production of the housing, and an element connected to the housing is produced by injection molding onto the housing, the at least one further opening remaining fluffy during the production of the housing is injected with the material of the element. Injection molding of the recesses can also be achieved in this way in a separate injection process, for example in a second injection molding step of a two-component injection process.
- a molded element for example a sealing element
- a simple manner which is arranged on both sides of the contact part, since the material of the molded element can pass from one to the other side of the contact part through at least one of the one or more recesses .
- the housing can be injection molded in a first step. In this step, the material of the housing can be replaced by one or more of the
- one or more of the recesses can be covered during the encapsulation with the housing, so that the material of the housing cannot enter these covered recesses.
- the cover can e.g. be ensured by the injection mold, in which, for example, a mandrel dips into the cover or a cover element covers the recess.
- these are free of one or more recesses and the material of the sealing element can flow through the recess and thus reach and harden on both sides of the contact part. In this way, an encapsulation of the housing and an injection of the seal can take place from only one side and there are no two separate ones
- the housing has a channel which runs from an opening of the housing to the exposed part of the contact part and the molded element is a sealing element for sealing a closure, in particular a cover, which can be used to close the opening.
- the material of the molded element is preferably a thermoplastic elastomer, preferably with a lower hardness than the material of the housing, by a better one
- Figures la-b show an embodiment of the cable lug 10 and an embodiment of a contact element 2 with the cable lug in an isometric view (Fig. La) and in a sectional view (Fig. Lb).
- the contact element 2 comprises an electrical conductor 4, which is coated with a conductor insulation 6 made of very soft polyurethane, for example with the Shore-A 80 hardness.
- One end 8 of the conductor 4 is stripped and ultrasonically welded in an electrically conductive manner to a connection area 9 of a cable lug
- the cable lug 10 has a flat annular contact part 11 with a fastening recess in the form of a central bore 12 and a plurality of smaller further recesses 13 arranged around it.
- the cable lug 10 and an adjoining section 14 of the electrical conductor 4 is extrusion-coated with an electrically insulating housing 16 made of a polyurethane, a part 17 of the contact part 11 with the bore 12 being exposed.
- the extrusion coating is carried out so that some of the further recesses 13 of the
- the housing 16 forms a first connector 18 with a first channel 20, which extends from a first opening 22 of the housing to the exposed part 17 of the contact part
- a sealing element 30 with annular sealing lips 32 is injection molded onto the housing 16, which consists of a softer plastic than the housing 16, for example of thermoplastic polyethylene. Some more of the plurality of recesses 13 of the contact part 11 are sprayed with the material of the sealing element 30. This allows a one-piece sealing element 30 on both sides of the contact part 11, here in the first and second channels 20, 26.
- a cover 34 is captively connected to the housing 16 via a thread-like holding element 32.

- the connecting part 40 has a slightly conical and electrically insulating base 44 with an electrically conductive threaded bolt 46 made of metal.
- Recesses 13 of the contact part 11 and their arrangement around the fastening recess 12 achieve a strong anchoring of the contact part in the housing 16, so that the large forces which may occur when the nut 48 is screwed tight cannot release the contact part 11 from the housing 16 .
- the sealing element 30 presses against the outside of the base 44 in the second channel and thereby seals the contact element 2 from the side of the second opening 28. Sealing on the part of the first opening 22 takes place by placing the cover 34 on the first connecting piece 18, the sealing element 30 pressing against the outside of an inner contour 50 of the cover 34 and thereby effecting a watertight seal.
- the cover 34 and the housing 16 have complementary fastening means in the form of latching lugs 52 on the first connecting piece 18 and tabs 54 on the lid 34, the latching lugs 52 by rotating the attached cover 34 into the tabs 54 can be locked. Locking is also possible, for example, by placing and snapping in a transverse movement.
- a further complementary fastening means can be on the cover 34
- Undercut 58 may be provided which engage one behind the other when the cover 34 is rotated.
- the contact element 2 enables safe and tight contacting of the electrical conductor 4 with the connecting part 40 of the electrical system 42.
