Definitions
- the invention relates to a device for connecting high-voltage conductors comprising at least one first high-voltage conductor, at least one second high-voltage conductor, a device for receiving the first and second high-voltage conductor and at least one connecting device for electrically connecting the at least one first high-voltage conductor to the at least one second High-voltage conductor according to the preamble of claim 1.
- the object of the invention is to create a device for connecting high-voltage conductors by means of which at least two high-voltage conductors can be connected in a process-safe manner in a cost-effective manner.
- a preferred field of application of the invention is rich in automotive applications, in particular applications in electromobility.
- the present invention it is possible to achieve a cost-effective, process-reliable connection of high-voltage conductors, which is also easy to handle.
- the inventive device for connecting high-voltage conductors comprises at least one first high-voltage conductor, at least one second high-voltage conductor, a housing part as a device for receiving the first and second high-voltage conductor and at least one connecting device for electrically connecting the at least one first high-voltage conductor to the at least one second high-voltage conductor.
- the housing part has a first receiving space for the first high-voltage conductor and a second receiving space for the second high-voltage conductor and is designed as an extruded profile.
- An extruded profile can be produced very inexpensively by the meter, also represent complex structures of the receiving spaces and can be cut to any length for different devices.
- the housing part having the receiving spaces is made of a highly thermally conductive plastic.
- the highly thermally conductive plastic consists of a polymer material provided with thermally conductive boron nitride fillers, in particular PA6, PA66, PBT, PPS, PEEK, LPS or TPE.
- thermally conductive boron nitride fillers in particular PA6, PA66, PBT, PPS, PEEK, LPS or TPE.
- Such a material can be obtained from 3M®, for example.
- the device for receiving the high-voltage conductor has at least one first receiving space for the first high-voltage conductor and at least one second receiving space for the second high-voltage conductor, which have a common open connection area through a recess, which is a directly contacting system of the first High-voltage conductor and the second high-voltage conductor together allows.
- the receiving spaces are adapted to the contour of the high-voltage conductors, which are designed, for example, as busbars with a rectangular cross section and can be pushed into the receiving spaces in a simple manner from the outside.
- the receiving spaces thus produce, on the one hand, a form-fitting mounting of the high-voltage conductors, at least in two dimensions, and, on the other hand, also form an abutment against a compressive force exerted by a spring of a connecting device.
- At least one further receiving space for at least one connecting device is advantageously arranged in the common housing part of the device. This enables a particularly compact design and pre-assembly of the connec tion devices in this housing part before it is connected to neighboring housing parts.
- An advantageous further development of the invention provides that cooling channels for guiding a particular liquid cooling medium are provided adjacent to the receiving spaces for the high-voltage conductors.
- the device can be manufactured in a weight-saving manner, which is particularly useful for use in the automotive sector,
- the plastic ensures excellent electrical insulation of the high-voltage conductors from the environment.
- An advantageous addition to the invention provides that at least two cooling channels are connected by at least one connecting channel, which in at least at least one tightly adjoining at least one end face of the extruded profile, the terminating part is formed.
- a terminating part with integrated connection channels ensures, on the one hand, a clean end-face closure of a housing part produced as an extruded profile and, on the other hand, enables a simple meandering connection and guidance of a cooling medium through the cooling channels.
- a seal is preferably arranged between the terminating part and the front end of the extruded profile, in which the connection areas between the cooling channels and the connection channels are correspondingly cut out.
- the terminating part can also be permanently glued tightly to the end face of the extruded profile.
- the housing part forming the receiving spaces has fastening devices for connecting to at least one adjacent housing part. These can be designed as threaded bores made perpendicular to the extrusion direction of the housing part or, alternatively, as form-fitting receiving spaces for hexagon or square nuts that are directly formed in the extrusion process.
- Fig. 1 is a laterally broken perspective view of the device according to the invention
- Fig. 2 is a vertical partial section through the device in a central housing part of the subordinate device for receiving the high-voltage conductor and the connec tion devices;
- FIG. 1 shows a device 10 for connecting high-voltage conductors.
- a device 10 for connecting high-voltage conductors.
- Such a device 10 is used, for example, in the field of electromobility. Electrical energy fed into the device 10 via high-voltage leads 25, which is supplied, for example, by a battery module, not shown, is inside the device 10 via a first high-voltage line 20, which has a horizontal section 21 and vertical sections 22, into a Conductive connection with at least one second high-voltage conductor 30 brought ge.
- the device 10 has a total of three housing parts 12, 14 and 16, of which a first upper housing part 12 establishes the connection from the high-voltage supply lines 25 to the first high-voltage conductor 20.
- a second, middle housing part 14 forms first receiving spaces 143 for the vertical sections 22 of the first high-voltage conductor 20, second receiving spaces 142 for the second high-voltage conductor 30 and further receiving spaces 147 for connection devices 40.
- the second receiving spaces 142 for the second high-voltage conductor 30 are L-shaped in cross-section. Immediately adjoining the horizontal leg of the wall of the L-shaped cavity of the second receiving spaces 142 is a first receiving space 143 at the top, into which a vertical section 22 of a first high-voltage conductor 20 opens from above.
- the vertical section 22 penetrates a recess 149 in an upper horizontal cover plate of the housing part 14 3). Through this recess 1425, the vertical section 22 of the first high-voltage conductor 20 and the second high-voltage conductor 30 come into direct contact with one another and are there pressed together by the pressure of a connecting device described below.
- the housing part 14 Immediately adjacent to this contact area of the first high-voltage conductor 20, 22 and the second high-voltage conductor 30 or to the first receiving spaces 143, the housing part 14 has, in a horizontal position, a further receiving space 147 for the connecting device 40.
- the connecting device 40 has a contact bolt 41 which is connected at its end facing the vertical section 22 of the first high-voltage conductor 20 to a cylindrical or cuboid-shaped pressure piece 43.
- the pressure piece 43 penetrates an opening 146 between the receiving spaces 147 and 143, the shape of which is adapted to its cross section. The opening 146 thus also serves to guide the pressure piece 43.
- the pressure piece 43 has a spherical cap-shaped or lens-shaped contour 44 on its end face facing the vertical section 22.
- the pressure piece 43 is acted upon on its other end face by a first end egg ner designed as a compression spring spring 42 which surrounds the contact pin 41 and is supported with a second end on an abutment 148 delimiting the further receiving space 147.
- a first end egg ner designed as a compression spring spring 42 which surrounds the contact pin 41 and is supported with a second end on an abutment 148 delimiting the further receiving space 147.
- an adjusting device 45 which can be formed as an adjusting nut, for example, the preload of the spring 42 and / or the spring travel by which the pressure piece 43 can deflect against the pressure of the spring 42 can preferably be adjusted.
- the pressure piece 43 with its rounded contour 44 is pressed against the vertical section 22, whereby the first high-voltage conductor 20 comes into a conductive connection with the second high-voltage conductor 30.
- the contact pressure of the spring 42 is chosen so that even high currents of more than 100 A at high voltages of, for example, 400 V under all external conditions affecting a vehicle (vibrations, shocks, temperature fluctuations, moisture) reliably and largely without losses will wear.
- the lower end of the vertical section 22 is preferably provided with a bevel 23 wedge-shaped. This bevel 23 enables the vertical section 22 to be pushed into the receiving space 143 from above when the first high-voltage conductor 30 is already installed and the pressure piece 43 loaded by the spring 42 with its rounded contour 44 is pushed to the side accordingly.
- a plurality of cooling channels 144 are provided adjacent to the receiving spaces 142 and 143 for the high-voltage conductors 22 and 30, respectively.
- a liquid coolant is pumped through the cooling channels 144, which is used to dissipate heat from the connection area of the high-voltage conductors 22 and 30, which inevitably occurs due to the transmission of high electrical powers.
- the middle housing part 14 is made as an extruded profile 145, particularly preferably from a highly thermally conductive plastic. This choice of material achieves several advantages at the same time:
- the device 10 can be manufactured in a weight-saving manner, which is particularly useful for use in the automotive sector,
- the plastic ensures excellent electrical insulation of the high-voltage conductors20, 21, 22; 30 compared to the environment.
- thermally conductive plastic in particular polymeric material provided with thermally conductive boron nitride fillers, in particular made of PA6, PA66, PBT, PPS, PEEK, LPS or TPE, such as can be obtained, for example, from 3M®.
- cooling channels 144 can be connected to one another in a meandering shape by U-shaped connecting channels 151, the connecting channels 151 preferably being arranged in a terminating part 150 which tightly closes the central housing part 14 formed as an extruded profile 145 at least on one end face .
- the seal is brought about either by a seal 155 cut out in the area of the cooling channels 144 or the connecting channels 151 or by a corresponding permanent adhesive bond at the same point.
- the first housing part 12 and the middle housing part 14 are connected to one another by connecting screws 18 shown in FIG. 1 and fastening devices 141 provided in the middle housing part 14.
- the fastening devices 141 can be formed by threads worked into the middle housing part 14. Alternatively, rectangular receiving channels for the form-fitting reception of hexagonal or square nuts with through bores arranged above it are possible, through which the connecting screws 18 are screwed into the relevant nuts.
- the lower housing part 16 is connected to fastening devices 141A on the middle housing part 14 by connecting screws 18A.
- a plurality of flux voltage conductors than the two flux voltage conductors 20, 30 shown in the exemplary embodiment can be connected by appropriate connecting devices 40. It is also possible, please include to connect two or more superimposed floch volt conductors 20, 30 by several connecting devices 40 arranged next to one another or one behind the other, with an even stronger connection of the floch volt conductors then being achieved by several pressing forces generated by springs 42.
