Description

Technical Field

[0001] The invention relates to the assembly of a conductor which is designed in particular for use in a vehicle, in particular a motor vehicle. The invention also relates to a method for assembling a conductor which is designed in particular for use in a vehicle. Background Art

[0002] The assembly of conductors is known, for example, from AT 017 394 U1, DE 10 2021 107 921 B4, DE 297 12306 U1, US 2021 / 0119376 A1, DE 10 2019 119 468 A1, WO 2023 / 024971 A1, US 2022 / 0224059 A1 or DE 10 2022 103 647 A1, in which the stranded conductors are each provided with corresponding connection possibilities. AT 017394 U1, DE 297 12 306 U1 and DE 10 2021107 921 B4 are coaxial conductors.

[0003] Electric vehicles of the future will be charged with very high current intensities, which are approximately 600-1000A, as shown, for example, in DE 10 2021 107 921 B4. In order to be able to transmit such current intensities, very high wire cross-sections are required. In automobile construction, for the sake of reducing costs and reducing the weight of components, it is necessary to produce electrical wires made of light metals (such as aluminum and its alloys). Here, conductors made of solid materials are increasingly used instead of stranded wires. When these wires are in electrical contact with contact elements, problems with contact arise. In particular, flat conductors or individual conductors are mainly used. These conductors used are particularly rigid conductors, which involve expensive bending processes and costly manufacturing steps using many components.

[0004] There is therefore a need for an improved assembly line which can be assembled by a simpler process and with less material and production effort and which can withstand the mechanical stresses in a motor vehicle and is suitable for high current intensities. Summary of the invention

[0005] Therefore, a technical problem to be solved by the present invention is to provide an assembly conductor and a method for assembling a conductor in a manner that is as simple as possible in construction, by which a connection of a round conductor (in particular a coaxial conductor) to another conductive contact element can be achieved so that there is as low a resistance as possible between the contacts.

[0006] The described embodiments also apply to the method for assembling a conductor. Even if not described in detail, synergistic effects can also be produced by different combinations of embodiments.

[0007] According to one aspect of the present invention, a wire assembly is described by the following elements, which are not limited thereto. The wire assembly has a wire with at least two coaxially arranged conductors, wherein the wire ends are deinsulated. In addition, the wire assembly has a base body, the wire with the deinsulated wire ends is arranged in the base body, and the wire assembly also has at least one first conductive plate-shaped element and a second conductive plate-shaped element. At least one first conductive contact socket and a second conductive contact socket are arranged side by side in the base body. The first conductive plate-shaped element extends between the first contact socket and the deinsulated wire ends, wherein a first side of the first plate-shaped element is connected to the first contact socket, and the other side of the first plate-shaped element opposite to the first side is connected to the deinsulated wire ends in a material bonded manner. The second conductive plate-shaped element extends between the second contact socket and the deinsulated wire ends, wherein a first side of the second plate-shaped element is connected to the second contact socket, and the other side of the second plate-shaped element opposite to the first side is connected to the deinsulated wire ends in a material bonded manner.

[0008] In other words, the present invention proposes a twin-core wire, in particular a coaxial cable arranged in a matrix for use in a vehicle. Each of the two conductors of the wire is connected to a corresponding contact socket by a plate-shaped element, wherein the connection of the wire and the contact socket is realized by a corresponding plate-shaped element, and the plate-shaped element is connected to the wire in a material-bonded manner. With the structure according to the present invention for assembling the wire, the two conductors of the wire can be installed before the bending process of the wire, that is, the conductor can be assembled as a whole. Each contact element, such as each contact socket, as an interface between the wire and an adjacent high-voltage component in a vehicle, for example, can be manufactured together in one manufacturing step. The present invention realizes the assembly of a coaxial wire comprising a conductor made of a rigid light metal. Compared with a flat conductor, the use of a coaxial conductor can achieve a lower electromagnetic compatibility (EMC) load, a simpler bending process, fewer components and fewer manufacturing steps. Through the present invention, a rigid round conductor, in particular a rigid coaxial cable, can be assembled. By adopting a matrix for the integrity of all components (such as contact elements and plate-shaped elements and wires) arranged therein, the matrix can be limited to one component, which therefore leads to a reduction in the number of components and thus leads to a reduction in cost. The use of a cable with coaxially arranged conductors, i.e. in particular round conductors, allows integration into the vehicle using fewer connection points due to the higher rigidity of the coaxial cable and simplifies the installation of the mounting cable in the vehicle, in particular simplifies the automation of this installation. Due to the use of coaxially arranged conductors, a mounting cable constructed in this way enables a simpler bending process, thereby simplifying the integration in the installation space, i.e. integration in the vehicle.

[0009] The term "wire assembly" is to be understood in particular to mean the production of wires or cables, cable harnesses and complete cable harnesses that are ready for connection, with plugs, contacts and connection sleeves. Wires are primarily used to supply electrical loads, in particular in vehicles. In this way, the wire assembly can, for example, have / become a plug that can be used with a mating plug, in particular screwed to the mating plug. The mating plug can, for example, be part of a charging socket or a high-voltage accumulator.

[0010] The term "two coaxially arranged conductors" can be understood in particular to mean a coaxial wire, i.e. a coaxial cable, which consists of at least two coaxially arranged round conductors. For example, the wire used in the present invention can consist of the following elements: an inner conductor, in particular a light metal such as aluminum, which serves as, for example, a DC negative conductor; an inner insulator built on the inner conductor; an outer conductor connected to the inner insulator, the outer conductor being made in particular of a light metal such as aluminum, which serves as a DC positive conductor; and an outer insulator further connected to the outer conductor.

[0011] The term "deinsulated conductor end" is to be understood in particular to mean the exposure of the conductive part of the conductor. That is, the two conductive conductors of the conductor are exposed from their insulation so that contact with these conductors can be achieved by the remaining components of the assembly conductor. For example, the exposure or insulation of these conductors can be an additional method step in the production of this assembly conductor.

[0012] The term "conductive plate-shaped element" may in particular be understood to mean a flat element, which is obtained, for example, by a punching process. For example, the plate-shaped element may be a punched sheet made of a conductive material.

[0013] The term "material-bonded connection" is to be understood in particular to mean the contacting of two corresponding elements, whereby a conductor or an exposed conductor end is brought into contact with a corresponding plate-shaped element by using a method or a manufacturing process which connects the two parts to one another in a material-bonded manner. In particular, a material-bonded connection is to be understood to mean the connection of two parts by laser welding. In the case of conductors used in the assembly conductors according to the invention, in particular aluminum conductors are used, which can be contacted by a material-bonded connection to provide a strong and permanent electrically conductive connection. Aluminum materials can form an oxide layer on the surface, which in a purely force-fit connection leads to high electrical resistances under adverse environmental conditions. To avoid this, the invention employs a material-bonded connection to the insulated conductor ends of the conductors.

[0014] The contact socket can be a copper socket in particular. The mating contacts in the charging socket or the high-voltage storage device are typically made of copper and coated with silver. Thus, when selecting the material of the contact socket, the same material as the mating contact can be selected to avoid corrosion under adverse environmental conditions and to ensure low resistance.

[0015] In one embodiment of the invention, the first contact socket can have a first connection surface and the second contact socket can have a second connection surface, wherein the first connection surface and the second connection surface are oriented in the same direction, wherein the first connection surface and the second connection surface of the contact socket are arranged side by side in the same plane, and / or wherein the plate-shaped elements extend from the contact socket to the deinsulated conductor end in the same plane at a distance from each other.

[0016] The term "connection surface" is particularly to be understood as meaning the surface which contacts the counterpart when installed, for example, in a car. This connection surface is again illustrated in detail in the figure. According to this embodiment, these connection surfaces should be in the same plane. If the connection surfaces are not in the same plane, the rigid connection produced by the coaxial wire cannot be screwed onto the two boxes with the required surface pressure. For this reason, the contact socket according to the invention is arranged so that its connection surfaces are in the same plane.

[0017] In one embodiment of the invention, the first contact socket and the first electrically conductive plate-shaped element can be connected to each other in a materially bonded manner, in particular by friction welding, wherein the second contact socket and the second electrically conductive plate-shaped element can be connected to each other in a materially bonded manner, in particular by friction welding. That is, the contact socket can be pressed against the plate-shaped element, for example against a punched sheet, on the end side with great force and welded on the end side by rotating about its own axis. The materially bonded contact connection of the plate-shaped element to the contact socket enables a reliable and firm connection of the two components, which connection can withstand the loads during use.

[0018] In one embodiment of the invention, the substrate may have two opposite openings on one side on which the conductors are arranged, the openings being provided so that the deinsulated conductor ends can be accessed, in particular for a material-bonded connection. In particular, the two opposite sides of the substrate may be open, i.e., forming opposite openings. The two opposite sides of the substrate may be completely open or partially open, so that a material-bonded connection can be made. This allows the conductors to be accessible during assembly. In particular, material-bonded connections require high power densities, such as laser welding of aluminum. The laser can penetrate the substrate through the opposite openings and thus avoid damage to the substrate.

[0019] In one embodiment of the present invention, the assembly wire can also have a cover for each opening for closing the corresponding opening, and the cover closes the corresponding opening in a liquid-tight manner, wherein the cover can be connected to the substrate material to seal the opening. The closure of the cover by material bonding to the substrate can be designed as an additional feature. The opening of the substrate can be sealed to protect the entire system of the assembly wire from environmental influences. According to a typical embodiment, the cover can be connected to the opening of the substrate using ultrasonic welding or laser welding. For example, if ultrasonic welding is used to connect the cover to the substrate, the same material can be used for the two parts, that is, for the cover and the substrate, so that the investment cost can also be lower.

[0020] In one embodiment of the invention, the contact socket may also have a screw centered therein, which is provided to connect the contact socket to a counterpart. For example, in a preferred embodiment, each of the contact sockets, i.e. the first contact socket and the second contact socket, may each have a screw centered therein. Thus, the contact socket used as a plug may be connected to a counterpart plug, which is, for example, part of a charging socket or a high-voltage storage device. According to this embodiment, a screw connection may be more preferred than a pure plug connection, since the contact resistance is lower here and a better conductive connection may therefore be provided.

[0021] In one embodiment of the present invention, the first contact socket connected to the first conductive plate-shaped element and the second contact socket connected to the second conductive plate-shaped element can be completely surrounded by the substrate. In particular, the substrate can be manufactured by an injection molding process, so that in this injection molding process, the corresponding contact socket and the corresponding conductive plate-shaped element can be completely surrounded by injection molding in one injection molding process step. As a result, the contact sockets are jointly, i.e., simultaneously surrounded by injection molding, and the positions of the electrical interfaces can have very small tolerances with each other and ensure their precise arrangement with each other. In addition, this also simplifies the manufacturing process of the assembly wire. By using a substrate, the number of components used can be reduced, which also leads to cost reduction at the same time.

[0022] In one embodiment of the invention, the first plate-shaped element and the second plate-shaped element can be formed of the same material as the two coaxially arranged conductors. If the plate-shaped element and the conductors of the wire are both made of the same material, a better material-bonded connection can be produced between these materials. In particular, a light metal such as aluminum is selected as the material. That is, if the conductor of the wire is made of aluminum, the plate-shaped element to which the wire is assembled is also formed of aluminum. For example, the plate-shaped element is made of the same aluminum alloy as the wire to achieve a good welded connection, for example the plate-shaped element and the wire can be made of the following materials: EN AW-1050 or ENAW-1370. Choosing the same material can reduce corrosion under adverse environmental conditions, so that the resistance in this connection situation remains as low as possible.

[0023] In one embodiment of the invention, the substrate can also have a supporting geometry arranged in the substrate, and wherein the supporting geometry can be configured to support the wire when the wire is introduced into the substrate. The supporting geometry is configured so that the wire can be easily inserted and automatically centered. The process of introducing the wire into the substrate is thus simplified, and the supporting geometry can be used to bring the wire to the correct position on purpose. In addition, the supporting geometry can be arranged on the inner side of the wall of the substrate and extend inwardly into the substrate, wherein the wire is introduced on the outer side of this wall of the substrate. Through this construction, the wire is guided in the substrate by means of the supporting geometry and the wire is supported in its position so that the wire is brought into the correct position relative to the two plate-shaped elements.

[0024] Furthermore, the support geometry can have an introduction bevel for centering the conductor in the base body. This ensures that the conductor is guided to the correct position and centered in the base body when it is introduced into the base body. In particular, if the conductor consists of an inner and outer round conductor, which in a simplified geometry can be described as a conventional cylinder, it is advantageous to provide a bevel, which also leads to the inner conductor of the conductor being connected to other elements of the assembly of the conductor in the correct position.

[0025] According to one aspect of the invention, a method for assembling a conductor, in particular for use in a motor vehicle, is described. The method comprises the following steps: providing a conductor with an exposed, deinsulated conductor end; providing a first contact socket and a second contact socket; arranging a first conductive plate-shaped element and a second conductive plate-shaped element such that the first conductive plate-shaped element extends between the first contact socket and the deinsulated conductor end, and the second conductive plate-shaped element extends between the second contact socket and the deinsulated conductor end; connecting the first contact socket to one side of the first plate-shaped element; connecting the second contact socket to one side of the second plate-shaped element; surrounding the outer sides of the contact socket, the first plate-shaped element and the second plate-shaped element with plastic material to form a base; connecting the other side of the first plate-shaped element to the deinsulated conductor end in a material-bonded manner; connecting the other side of the second plate-shaped element to the deinsulated conductor end in a material-bonded manner.

[0026] In this method, the steps are not limited to the order of the steps described above, but the order described above represents a preferred embodiment of this method. However, additional method steps may also be added or other method steps may be removed, or existing method steps may be divided.

[0027] In other words, the method can be carried out as follows, for example. Conductive components, i.e., wires, first contact sockets, second contact sockets and conductive plate-shaped elements are provided and arranged so that the conductive plate-shaped elements can provide contact between the corresponding contact sockets and the corresponding conductors of the wires. Each contact socket is connected to one side of the plate-shaped element. After the contact sockets are aligned and connected to the plate-shaped elements, the contact sockets are surrounded by the matrix by forming a matrix. Then, the other side of the corresponding plate-shaped element is connected to the deinsulated wire end materially, i.e., connected to the corresponding conductor of the wire.

[0028] In one embodiment of the present invention, the connection of the insulated wire end to the first conductive plate-shaped element and the connection of the insulated wire end to the second conductive plate-shaped element can be performed by laser welding. The ideal connection of soft metals (especially aluminum as a conductor) to another conductive metal can be achieved by a material-bonded connection. Aluminum forms an oxide layer on the surface, which causes high resistance under adverse environmental conditions when connected without force. However, the challenge faced by welding is that the introduced heat may damage the internal insulation of the conductor, especially the internal insulation of coaxial wires. The melting point of aluminum is 660°C, which is many times higher than the maximum allowable temperature of ordinary insulation materials (approximately 120°C to 100°C). By using laser welding of aluminum, aluminum is only melted very locally, and the insulation of the conductor can withstand this load. A strong and reliable welding process is very important to ensure the safe operation of the wire. Depending on the length of the wire and the geometry of the wire, the weld may be subjected to a large force, so it is necessary to make a precise connection to the welded part. This can be achieved by laser welding.

[0029] Furthermore, according to one embodiment of the present invention, the connection of the first contact socket to the first conductive plate-shaped element and the connection of the second contact socket to the second conductive plate-shaped element may be performed by friction welding.

[0030] In one embodiment of the invention, the step of surrounding the outer sides of the contact socket, the first plate-shaped element and the second plate-shaped element and the conductor can include surrounding by injection molding. This allows, for example, the contact elements of the contact socket to be surrounded by injection molding together with the insulating material in one manufacturing step. Compared with previous conductor assemblies, steps in the injection molding process can thus be saved. By surrounding all components by injection molding, a reliable and permanent alignment of the components at the corresponding component positions on the assembly conductor can be ensured.

[0037] Figure 1 A section of a mounting conductor 100 according to a typical embodiment of the present invention is shown. A conductor 106, which is shown here with a dashed arrow and is not shown in detail, has at least two coaxially arranged conductors 316, 318, which have deinsulated conductor ends. Furthermore, the mounting conductor 100 has a base body 101, inside which the conductor 106 with deinsulated conductor ends is arranged, and at least a first conductive plate-shaped element 104 and a second conductive plate-shaped element 105. At least a first conductive contact socket 102 and a second conductive contact socket 103 are arranged side by side in the base body 101. In particular, the two contact sockets 102 and 103 are arranged side by side with each other so that their respective midpoints are located on a common imaginary straight line. The first electrically conductive plate-shaped element 104 extends between the first contact socket 102 and the deinsulated wire end of the wire 106 (not shown here), wherein a first side of the first plate-shaped element 104 is connected to the first contact socket 102, and the other side of the first plate-shaped element 104 opposite to the first side is connected to the deinsulated wire end in a material-bonded manner. The second electrically conductive plate-shaped element 105 extends between the second contact socket 103 and the deinsulated wire end of the wire 106, wherein a first side of the second plate-shaped element 105 is connected to the second contact socket 103, and the other side of the second plate-shaped element 105 opposite to the first side is connected to the deinsulated wire end in a material-bonded manner.

[0038] The substrate 101 can extend over two associated or connected parts. In other words, the substrate 101 can be divided into two opposite parts, one of which has contact sockets 102, 103 and the other has a conductor 106. The two parts of the substrate 101 are connected by plate-shaped elements 104, 105 surrounded by the substrate 101. The plate-shaped element on one side of the conductor 106 is exposed in this part of the substrate 101 so that the plate-shaped element can be connected to the conductor 106. The first contact socket 102 and the first conductive plate-shaped element 104 are connected to each other in a material-bonded manner, in particular by friction welding. The second contact socket 103 and the second conductive plate-shaped element 105 are also connected to each other in a material-bonded manner, in particular by friction welding. The first contact socket 102 connected to the first conductive plate-shaped element 104 and the second contact socket 103 connected to the second conductive plate-shaped element 105 are completely surrounded by the substrate 101. In other words, the outer circumference of the contact sockets 102, 103 and the sides of the plate-shaped elements 104, 105 that are placed against (and thus conductively connected to) the contact sockets 102, 103 are surrounded by the base body 101. In particular, these parts are surrounded by the base body 101 by injection molding.

[0039] The plate-shaped elements 104, 105 extend in the base body 101 in the same plane at a distance from each other from the corresponding contact sockets 102, 103 to the deinsulated wire ends of the wires 106. In other words, the plate-shaped elements 104, 105 are arranged at the same height and extend in the same plane at the same height between the contact sockets 102, 103 and the wires 106 (or the deinsulated wire ends).

[0040] As in Figure 1 As can be seen in the figure, the base body 101 has two opposite openings 107 on the side on which the conductors 106 are arranged. Figure 1 , the base body 101 is illustrated from above, so that only the upper opening 107 is visible. The opening 107 is provided so that the deinsulated wire end can be accessed, in particular for a material-bonded connection. In addition, the base body 101 has a supporting geometry 108, which is arranged in the base body 101 and is designed to support the wire 106 when the wire 106 is introduced into the base body 101. The supporting geometry 108 is arranged on the inner side of a wall 109 of the base body 101 and extends inwardly into the interior of the base body 101, wherein the wire 106 is introduced on the outer side of this wall 107 of the base body 101. In addition, the supporting geometry 108 has an introduction bevel 110 for centering the wire 106 in the base body 101.

[0041] Figure 2 FIG. 1 shows a wiring harness 100 according to an exemplary embodiment of the present invention. The wiring harness 100 has a wiring harness having ... Figure 1The same elements as those already described in Figure 2 , the conductor 206 is integrated into the base body. The conductor 206 is sealed by a seal 214, in particular by a single-core seal 214. This seal 214 can be pushed onto the conductor 206 before being inserted into the base body 101.

[0042] In addition, a cover, namely a maintenance cover 213, is provided in the base body 101. The maintenance cover 213 is connected to the base body 101 with a folding hinge on one side and with screws on the other side. Figure 1 The screw connection of the maintenance cover 213 is now in Figure 2 102, 103. Figure 1 compared to, Figure 2 The assembly wire 100 in the figure is rotated in the extension direction of the plate-shaped elements 104, 105. Other locking mechanisms can also be used, such as locking mechanisms based on plastic clips. If the wire 206 is defective or during recycling after the product life, the assembly wire 100 can be disassembled, which is achieved by making the individual components of the assembly wire 100 accessible with a maintenance cover 213. In addition, in Figure 2 1 and 2 , for each of the openings 107, a corresponding cover 212 for closing the corresponding opening 107 is illustrated, the cover 212 closing the corresponding opening 107 in a liquid-tight manner. The cover 212 can be connected to the base body 101 in a material-bonded manner to hermetically seal the opening 107. In addition, each of the contact sockets 102, 103 has a central screw 211 located therein, which is provided to connect the corresponding contact socket 102, 103 to a counterpart.

[0043] Figure 3 Shows Figure 2 FIG. 2 is a cross-sectional view AA of a wire assembly 100 according to an exemplary embodiment of the present invention. Figure 3 The assembly wire in the Figure 1 and Figure 2 All the features described in. Figure 3 107a and 107b with their associated covers 212a and 212b of the base body on the side of the conductor 206. The extension of the plate-shaped element 104 from the exposed conductor end of the conductor 206 to the contact socket 102 can also be seen. It is also clear that the conductor 206 is deinsulated within the interior of the base body. That is, the inner conductor 316 is exposed and here contacts the plate-shaped element 104 and is thus electrically connected to the contact socket 102. The inner insulator 317 is also exposed, as is the outer conductor 318, which is connected to the further plate-shaped element 105 and the further contact socket 103 (but here in the inner insulator 317). Figure 3 Here, too, the outer insulation 319 is shown as the beginning of the deinsulated conductor end.

[0044] The two plate-shaped elements 104, 105 are connected in a plane to the conductors 316, 318 to which they belong and are connected respectively. In the present embodiment, this is preferably achieved by a short surface on the edge of the plate-shaped elements 104, 105, wherein if necessary, this short surface can also be a large surface, such as the upper side or the lower side of the plate-shaped elements 104, 105. Compared with the latter case, the short surface has the advantage that more space can be left for installation activities (such as welding activities). The connection between the plate-shaped elements 104, 105 and the conductors 316, 318 through the plane of the corresponding plate-shaped elements 104, 105 also realizes a simple formation of a weld seam or a similar seam for connection, such as a soldering seam, if the conductors 316, 318 are round conductors and the connection to the plane is formed tangentially, because a natural wedge remains between the two components, which can be used to form the connection as needed.

[0045] The first contact socket 102 has a first connection surface 315 and the second contact socket 103 also has a second connection surface, although not visible here, which are oriented in the same direction, wherein the first and second connection surfaces 315 of the contact sockets 102 , 103 are arranged next to each other in a plane.
