  • An object of the invention is therefore to create a prefabricated cable and a method for assembling a cable using means that are as simple as possible in terms of construction, with which the connection of round conductors, in particular coaxial conductors, to other electrically conductive contact elements can be realized, so that the lowest possible electrical resistance prevails between this contact.
  • a prefabricated cable is described with the following elements, which are not exclusively limited thereto.

Furthermore, the prefabricated cable has a base body in which the cable with the stripped cable end is arranged, and furthermore at least a first electrically conductive plate-shaped element and a second electrically conductive plate-shaped element. In the base body, at least a first electrically conductive contact socket and a second electrically conductive contact socket are arranged next to one another. arranged.
  • the first electrically conductive plate-shaped element extends between the first contact socket and the stripped cable end, wherein one side of the first plate-shaped element is connected to the first contact socket and another side of the first plate-shaped element opposite the first side is materially connected to the stripped cable end.
  • the second electrically conductive plate-shaped element extends between the second contact socket and the stripped cable end, wherein one side of the second plate-shaped element is connected to the second contact socket and another side of the second plate-shaped element opposite the first side is materially connected to the stripped cable end.
  • the present invention proposes a two-wire cable, in particular a coaxial cable for use in vehicles, which is arranged in a base body.
  • Each of the two conductors of the cable is connected to a corresponding contact socket by means of a plate-shaped element, wherein the connection of the cable and the contact socket takes place via the respective plate-shaped element, which plate-shaped element is integrally connected to the cable.
  • the two conductors of the cable can be assembled before the cable is bent, i.e., they can be assembled as a whole.
  • the contact elements, such as the contact sockets which represent the interface of the cable to, for example, adjacent high-voltage components in the vehicle, can be manufactured together in a single production step.
  • the present invention makes it possible to assemble a coaxial cable from conductors made of a rigid light metal. Compared to flat conductors, the use of coaxial conductors leads to lower electromagnetic compatibility (EMC) loads, a simpler bending process, fewer components, and fewer production steps.
  • EMC electromagnetic compatibility
  • rigid round conductors, in particular rigid coaxial cables can be assembled.
  • the base body can be limited to a single component, thus resulting in a reduction in the number of components and thus in costs.
  • prefabricated cable refers in particular to the production of ready-to-connect cables, cable bundles, and complete wiring harnesses with connectors, contacts, and terminal sleeves. These cables can be used primarily to supply electrical power to consumers, particularly in motor vehicles.
  • a prefabricated cable can, for example, have/represent a connector that can be used with a mating connector, particularly one that is screwed together.
  • the mating connector can, for example, be part of a charging socket or a high-voltage storage device.
  • two coaxially arranged conductors refers, in particular, to a coaxial line, i.e., a coaxial cable, which consists of at least two coaxially arranged round conductors.
  • a line used in the present invention can consist of the following elements: an inner conductor, in particular made of a light metal such as aluminum, which represents, for example, the DC negative conductor, an inner insulation based thereon, an outer conductor, in particular made of a light metal such as aluminum, which represents the DC positive conductor, and further an outer insulation.
  • stripped cable end refers specifically to the exposure of the conductive parts of the cable. This means that the two electrically conductive conductors of the cable are stripped of their insulation, allowing contact between these conductors via the remaining components of the pre-assembled cable. Exposing or insulating these conductors can, for example, represent an additional process step in the production of such a pre-assembled cable.
  • electrically conductive plate-shaped element can be understood in particular as a flat element which is obtained, for example, by a stamping process
  • the plate-shaped element can be a stamped sheet made of an electrically conductive material.
  • material-to-material connection can be understood in particular as the contacting of the two corresponding elements, in this case the contacting of the cable, or the exposed cable ends, with the respective plate-shaped element using a method or a manufacturing process that connects these two parts in a material-to-material manner.
  • the material-to-material connection is understood as a joining of the two parts by laser welding.
  • the conductor used in the prefabricated cable according to the invention is, in particular, an aluminum conductor, which can be contacted by means of a material-to-material connection in order to provide a firm and permanent electrically conductive connection.
  • the material aluminum can form an oxide layer on its surface, which, in the case of a purely force-to-material connection, leads to high electrical resistance under unfavorable environmental conditions.
  • the present invention relies on a material-to-material connection to the insulated cable ends of the cable.
  • the contact sockets can, in particular, be copper sockets.
  • the mating contacts in charging sockets or high-voltage storage devices are also typically made of copper and coated with silver. This allows the contact socket to be made of the same material as the mating contacts to prevent corrosion under adverse environmental conditions and ensure low electrical resistance.
  • the first contact socket can have a first connection surface and the second contact socket can have a second connection surface, which first and second connection surfaces are aligned in the same direction, wherein the first and second connection surfaces of the contact sockets are arranged next to one another on a plane and/or wherein the plate-shaped elements extend at a distance from one another on a same plane from the contact socket to the stripped line end.
  • connection surface refers in particular to the surface that comes into contact with the counterpart during installation, for example, in a motor vehicle. This connection surface is shown in detail in the figures. According to this embodiment, these connection surfaces should be on one plane. If the connection surfaces were not on one plane, the rigid connection created by the coaxial cable could not be screwed to both boxes with the required surface pressure. For this reason, the contact sockets according to the invention are arranged with their connection surfaces on one plane.
  • the first contact socket and the first electrically conductive plate-shaped element can be connected to one another by a material fit, in particular by friction welding, wherein the second contact socket and the second electrically conductive plate-shaped element can be connected to one another by a material fit, in particular by friction welding.
  • the contact sockets can be pressed with high force against the plate-shaped elements, for example against the stamped sheets, and welded to the end faces by rotation about their own axis.
  • a material-fit connection between the plate-shaped elements and the contact sockets enables a secure and firm connection between these two parts, which can withstand the stresses during use.
  • the base body can have two opposing openings on the side on which the cable is arranged, which openings are provided to enable access to the stripped cable end, in particular for a material-to-material connection.
  • two opposing sides of the base body can be open, i.e. they form opposing openings. These two opposing sides of the base body can be either completely open or partially open, so that a material-to-material connection can be made. This enables access to the cable during the assembly process.
  • a material-to-material connection such as laser welding of aluminum, requires a high power density. The laser can shine through the opposing openings through the base body, thus avoiding damage to the base body.
  • the prefabricated cable may further comprise a cover for each of the openings for closing the respective opening, which cover each opening is sealed in a liquid-tight manner, wherein the covers can be integrally connected to the base body to seal the openings.
  • the sealing of the cover by means of a liquid-tight connection to the base body can be designed as an additional feature.
  • the openings of the base body can be sealed tightly to protect the entire system of the prefabricated cable from environmental influences.
  • the covers can be connected to the openings of the base body by means of ultrasonic welding or laser welding. If, for example, ultrasonic welding is used to connect the cover to the base body, the same material can be used for both parts, i.e. for the covers and for the base body, so that the investment costs can also be lower.
  • the contact socket can further comprise a screw centered therein, which is intended to connect the contact socket to a counterpart.
  • each of the contact sockets i.e., the first and also the second contact socket, can each comprise a screw centered therein.
  • the contact socket which functions as a plug, can be connected to a counterpart plug, for example, a part of a charging socket or a high-voltage battery.
  • a screw connection can be preferable to a pure plug connection, since the contact resistance is lower here and thus a better electrically conductive connection can be provided.
  • the first contact socket, which is connected to the first electrically conductive plate-shaped element, and the second contact socket, which is connected to the second electrically conductive plate-shaped element can be completely surrounded by the base body.
  • the base body can be manufactured by means of an injection molding process, so that in this injection molding process, the respective contact sockets and the respective electrically conductive plate-shaped elements can be completely overmolded in a single injection molding process step. Because the contact sockets are overmolded together, i.e. simultaneously, the position of the electrical interfaces relative to one another can have very close tolerances and their precise arrangement relative to one another can be ensured. Furthermore, this simplifies the manufacturing process of the prefabricated cable. By using a base body The number of components to be used can be reduced, which also results in a reduction in costs.
  • the first plate-shaped element and the second plate-shaped element can be formed from the same material as the two coaxially arranged conductors. If both the plate-shaped elements and the conductors of the cable are formed from the same material, a better material-fit connection can be created between these materials.
  • a light metal is selected as the material, such as aluminum.
  • the plate-shaped elements of the prefabricated cable are also made of aluminum.
  • the plate-shaped elements are made of the same aluminum alloy as the cable to enable a good welded connection; for example, they can be made of the following materials: EN AW-1050 or EN AW-1370. Selecting the same materials can reduce corrosion under unfavorable environmental conditions, so that electrical resistance in this connection remains as low as possible.
  • the base body can further comprise a support geometry which is arranged in the base body and which can be configured to support the line when it is inserted into the base body.
  • the support geometry is designed such that the line can be easily pushed in and centers itself. This simplifies insertion of the line into the base body and the line can be specifically brought into the correct position using the support geometry.
  • the support geometry can be arranged on an inner side of a wall of the base body and extend inwards into the base body, with the line being inserted on an outer side of this wall of the base body. With this configuration, the line is guided within the base body by means of the support geometry and supported in its position, such that the line is brought into the correct position relative to the two plate-shaped elements.
  • the support geometry can have insertion chamfers for centering the cable in the base body. This ensures that the cable is guided to the correct position and centered in the base body when inserted. This is particularly true if the cable consists of an inner and an outer round conductor, which in a simplified geometry can be described as a convoluted cylinder. It can be advantageous to provide insertion bevels which also guide the inner conductor of the cable to the correct position for connection to the other elements of the pre-assembled cable.
  • a method for assembling a cable in particular for use in a motor vehicle, comprises the following steps: providing the cable with an exposed stripped cable end, providing a first contact socket and a second contact socket, arranging a first electrically conductive plate-shaped element and a second electrically conductive plate-shaped element such that the first electrically conductive plate-shaped element extends between the first contact socket and the stripped cable end, and the second electrically conductive plate-shaped element extends between the second contact socket and the stripped cable end, connecting the first contact socket and one side of the first plate-shaped element, connecting the second contact socket and one side of the second plate-shaped element, enclosing the outer side of the contact sockets, the first and second plate-shaped elements and the cable with a plastic material to form a base body, materially connecting another side of the first plate-shaped element to the stripped cable end, materially connecting another side of the second plate-shaped element to the stripped cable end.
  • the steps are not limited to the above-mentioned order of steps, but the above-mentioned order represents a preferred embodiment of the method. However, further method steps may be added or other method steps may be removed, or existing method steps may be subdivided.
  • the method can, for example, proceed as follows.

In the present embodiment, this is preferably done with a short surface on an edge of the plate-shaped elements 104, 105, although this can also be a large surface, such as the top or bottom of the plate-shaped elements 104, 105.
  • a short surface has the advantage over the latter that more space remains for assembly activities, such as welding activities.
  • connection between a plate-shaped element 104, 105 and the conductor 316, 318 via a flat surface of the respective plate-shaped element 104, 105 also enables simple formation a weld seam or a similar seam serving to form the connection, such as a solder seam, if the conductor 316, 318 is a round conductor and the connection to the flat surface is tangential, since then a natural gusset remains between these two assemblies, which can be used to form the connection if necessary.
  • the first contact socket 102 has a first connection surface 315 and the second contact socket 103 also has, but not visible here, a second connection surface, which first and second connection surfaces 315 are aligned in the same direction, wherein the first and second connection surfaces 315 of the contact sockets 102, 103 are arranged next to one another on one plane.
