Description

Technical Field

[0001] The invention relates to a cable or line which is configured with a plug-in profile for direct plugging into a socket, for example a socket on a mating connector, an interface, a contact socket or a plug. Background Art

[0002] In the prior art, there is no standardized terminology for plugs and sockets or male and female contacts. In the terminology of the present invention, male or female contacts are optionally used in plugs or sockets. Male contacts are generally non-elastic contact geometries, such as contact pins, contact pins, flat contacts, etc. Female contacts are elastic contacts, in which at least one elastic contact element is provided, which participates in contact with a mating contact.

[0003] In this respect, the plug-in connection is realized by a plug and a mating connector, wherein mutually corresponding or mutually influencing spring contacts and non-spring contact portions are optionally provided in each plug and mating connector.

[0004] Furthermore, a large number of connection solutions are known in the prior art for connecting electrical contact elements to electrical wires, such as stranded conductors. Conventional techniques such as welding, fusion, crimping, etc. are not discussed in this disclosure, as these methods are fully described in the prior art and are regulated in the IEC 60325 series of standards.

[0005] DIN EN 60352-2 contains requirements, tests and application notes for solderless crimps made with stranded conductors with a cross-section of 0.05 mm2 to 10 mm2 or solid conductors with a diameter of 0.25 mm to 3.6 mm and suitable uninsulated or pre-insulated crimp sleeves.

[0006] Currently, it is basically impossible to connect cables with larger cross-sections to contact elements in an efficient and economical way. Not only the manufacturing technology, but also the contact geometry and contact design are very complex and expensive.

[0007] Replacement drive components in automotive production are increasingly designed to be pluggable in terms of their electrical contacts in order to facilitate assembly and repair. Plug-in connections place extremely high demands on electrical contact properties, load capacity, sealing and installation space.

[0008] DE 10 2013 004 708 A1 relates to a copper stranded conductor for parallel and / or series connection of round plug-in contacts with a conductor cross section, wherein at least one section of the stranded conductor has a section with a compressed cross section, which has a reduced cross section and to which a cylindrical round plug-in contact socket or a cylindrical round plug-in contact pin is soldered.

[0009] Another significant problem in the prior art is the use of copper as a connecting medium, since copper is difficult or impossible to reliably connect to contact elements by soldering, which is required in the automotive industry.

[0010] If, for example, the removable plug-in contact is made of a first material which is different from copper or an alloy having a reduced copper content, particular problems are encountered when connecting the plug-in contact to a copper conductor.

[0011] Therefore, in the prior art, crimping is mainly used to establish the connection. Summary of the invention

[0012] The object of the present invention is therefore to provide a simple and economical solution for contacting an electrical interface with electrical lines.

[0013] This object is achieved by the combination of features according to patent claim 1 .

[0014] The basic idea of ​​the present invention is to transform the conventional wire (cable) so that the wire itself or the wire end is designed as an insertion profile. Therefore, according to the present invention, a method for manufacturing such an insertion profile at the wire end of a wire, especially a stranded wire, is proposed, comprising the following steps:

[0015] a. forming the wire at the end of the wire, in particular pressing the wire, by constructing a (preferably compacted) plug-in section with at least one flat surface section at the end of the wire,

[0016] b. Providing a contact belt (contact strip belt), wherein the contact belt has a plurality of elastic contact strips protruding from the contact belt, and

[0017] c. Installing and connecting the contact strip on the surface section.

[0018] Furthermore, according to the invention, a method for producing an insertion profile at a wire end of an electric wire, in particular a stranded wire, is proposed, comprising the following steps:

[0019] a. forming the wire at the end of the wire, in particular pressing the wire, by constructing a (preferably compacted) plug-in section with at least one flat surface section at the end of the wire,

[0020] b. Providing a contact belt (contact strip belt), wherein the contact belt has a plurality of elastic contact strips protruding from the contact belt, and

[0021] c. Installing and connecting the contact strip on the surface section.

[0022] In the method, at least one fastening element for a correspondingly constructed mating connector is also constructed in the flat surface section and / or directly adjacent to the flat surface section, in particular by forming and / or separating, further in particular by stamping, and / or is provided with a contact strip together with the at least one fastening element.

[0023] Furthermore, the term wire can also be understood as an electrical conductor, such as a rigid busbar. According to the invention, it is also conceivable to use a (solid) busbar and then perform steps b) and c) on the surface of the busbar instead of compacting or forming the wire.

[0024] In this case, the contact strip is mounted in such a way that the contact strip protrudes from the upper side opposite the connection side and acts as a spring strip during assembly with a mating plug-in element.

[0025] Furthermore, it is preferred that the wire has a substantially circular cross-sectional shape in the non-molded area immediately adjacent to the molded area. A circular shape in the sense of the present invention is a cross-sectional shape of a typical circular wire, which is not always a perfect circle but is approximately circular.

[0026] In another advantageous embodiment of the invention, it is provided that during the forming process, the wire section is formed and preferably compacted into a substantially cuboid shape. This should be achieved in such a way that the strands of the stranded conductor are locally thermally connected and pressed together, which can be achieved in particular by a compaction process.

[0027] It is therefore further advantageous that the wire end is processed by compaction, in particular to have a shape in which the plug-in section is configured with a flat upper side and a flat lower side substantially parallel to the upper side, thereby providing a simple plug-in profile whose basic shape is suitable for the plug-in process.

[0028] In another advantageous embodiment of the invention, provision is made for providing a contact strip in which a plurality of parallel arranged contact strips are provided and the contact strip is mounted on a surface section of the wire end in such a way that the parallel arranged contact strips are oriented along the direction of extension of the cable or transversely to the direction of extension of the cable, in particular at 90° thereto.

[0029] Alternatively, an embodiment is conceivable in which a contact strip is provided in which a plurality of parallel contact strips are provided and the contact strip is mounted on a surface section of the end of the wire in such a way that the parallel contact strips are oriented at an angle of 30° to 60°, preferably 45°, and / or 120° to 150°, preferably 135° to the direction of extension of the cable (L). This orientation of the contact strips at a corresponding angle to the direction of extension of the cable advantageously enables the wire to be inserted both in the direction of extension of the cable and at an angle of 90°.

[0030] In addition to the above-mentioned method, another aspect of the present invention also relates to an electric wire, in particular an electrical stranded conductor, which has a wire end configured as an insertable section, the insertable section having at least one flat surface section, in particular a planar surface section, and having at least one contact strip, which is directly mounted on the surface section and connected to the surface section, wherein the contact strip has a plurality of (elastic) spring contact pieces protruding from it.

[0031] Furthermore, the invention provides an electric line, in particular an electric stranded conductor, having an electric line end configured as a plug-in section, the plug-in section having at least one flat surface section, in particular a planar surface section, and having at least one contact strip, which is directly attached to the surface section and connected to the surface section, wherein the contact strip has or is provided with a plurality of (elastic) spring contact strips protruding from it. Furthermore, the plug-in section of the electric line end has at least one fastening element for correspondingly configuring the mating connector. In this case, in particular, the at least one fastening element is a locking element and / or a blocking element.

[0032] It is advantageous that a main latching part is provided for the electric wire in a simple, economical and space-saving manner (especially directly on the plug-in section) by means of a fastening element, which main latching part resists the extraction force acting on the electric wire and fixes the electric wire. The insulation of the electric wire is fastened in a correspondingly constructed mating connector, especially in a connector housing of a correspondingly constructed mating connector. Alternatively, the mating connector can also be constructed as and / or include an insulator. It is also advantageous that no additional components or assemblies are required to fasten the electric wire in the mating connector. In other words: the electric wire is fastened or can be fastened directly in, in or on the mating connector by the fastening element at the end of the electric wire, especially fastened in a detachable manner, especially in a mainly locked or mainly locked manner. In this way, a plug-in connector consisting of a plug and a mating connector can be provided that is particularly compact, small in size, easy to manufacture and economical.

[0033] In an advantageous embodiment of the invention it is provided that at least one fastening element is formed in the flat surface section and / or directly adjacent to the flat surface section. In this case, the fastening element is in particular a recess, more in particular a groove-shaped recess.

[0034] In an implementation variant, the electric wire according to the present invention is configured such that the at least one contact strip has the at least one fastening element. In addition, the at least one fastening element is particularly configured or shaped or designed as a spring element, a pin, a needle and / or a bayonet locking element.

[0035] In an advantageous embodiment of the electric line, it is provided that the electric line has a substantially circular cross-sectional shape in the non-shaped region immediately adjacent to the end-side plug-in section.

[0036] Another advantageous solution is that the contact strip has a sheet metal section at the edge of at least one edge region, to which a plurality of contact strips are connected on one side, while the other (opposite) end of the contact strips is designed as a free end.

[0037] The contact strips can be advantageously bent into a spoon tip shape so that the contact points of each contact strip are approximately located in the center of the surface segment along the direction in which the contact strips extend, and the ends of the contact strips terminate on or near the surface segment. To illustrate the preferred contact strip orientation, please refer to the drawings in the description of the embodiments.

[0038] In principle, however, other contact strip shapes are also conceivable. In any case, it is advantageous according to the concept of the invention if a plurality of contact strips, in particular 3, 4, 5, 6 or 7 contact strips, are arranged adjacent to each other.

[0039] In alternative embodiments, two opposing surface sections are configured on the plug-in section, and preferably a contact strip connected to the surface section is installed and fastened on each surface section. In this case, the contact strips can be aligned in mirror image or in the opposite direction.

[0040] In an advantageous embodiment of the electrical cable, it is further provided that at least one contact strip protrudes beyond the outer contour of the plug-in section laterally and / or at the end by means of projections, so that a corresponding projection forms an engagement surface or stop surface for interaction with a corresponding mating surface on a mating connector, which is shaped accordingly for assembly. The defined projections can optimize the connection and assembly with the mating plug-in element.

[0041] The contact strips are advantageously connected by material bonding, particularly preferably at a plurality of connection points.

[0042] The concept of the present invention is particularly applicable to electric wires with wire sheaths. In addition, in the method according to the present invention, before compaction or integral forming in a defined end section, the wire sheath is removed, and the remaining wire sheath can also be used as a stop to determine the insertion depth.

[0043] According to the invention, a plug-in connector is also provided, which has a plug and a correspondingly constructed mating connector. In this case, the plug is an electric wire, in particular an electrical stranded conductor, with a wire end formed with a plug-in section, the plug-in section having at least one flat surface section and at least one contact strip, which is directly mounted on the surface section and connected to the surface section. In addition, the contact strip has a plurality of contact strips protruding from it, in particular resilient spring contact strips. The plug-in section of the wire end has at least one fastening element for the correspondingly constructed mating connector. In particular, the at least one fastening element is a locking element and / or a latching element.

[0044] In an advantageous embodiment, the mating connector is constructed as a two-piece structure, and each part of the mating connector of the two-piece structure has mutually complementary fixing mechanisms. Thus, the two parts of the mating connector of the two-piece structure can be fastened to each other or fastened close to each other. BRIEF DESCRIPTION OF THE DRAWINGS
