Description

[0001] The present invention relates to a contactor, in particular a contactor for a DC charging port of an electric vehicle. The present invention further relates to a high-voltage box having such a contactor, as well as a method for installing such a contactor in a high-voltage box. The present invention further relates to a vehicle, in particular an electric vehicle, having such a high-voltage box.

[0002] Contactors are generally known to those skilled in the art. Contactors are also known as switchgear and circuit breakers, which typically have two positions: open and closed. Contactors are used primarily as safety shutdown devices. Unlike relays, contactors have load circuits designed for high switching capacities and can therefore safely and reliably connect and disconnect large power or loads. Contactors of the aforementioned type can switch loads of 100 A or more. Such contactors are therefore typically used in the DC charging port of an electric vehicle, where currents of up to 500 A can flow.

[0003] Contactors are usually part of an electric vehicle's high-voltage electrical system. Contactors are used, for example, to safely connect and disconnect the electrical system, especially the charging system, of the electric vehicle and the charging infrastructure, such as a charging cable at a charging station.

[0004] However, it has been shown that installing contactors in higher-level components of the electric vehicle's high-voltage electrical system architecture, such as a high-voltage box, is not easy. In particular, manufacturing tolerances of mounting connections within the high-voltage box and / or tolerances of the contactor housing may make installation of the contactor inadequate or compromise mechanical and / or electromechanical specifications.

[0005] Document CN 1 13 838 707 A discloses relays. The relay comprises a housing, a coil, a circuit breaker protection assembly, a current detection assembly, and an arc extinguishing assembly. The housing includes a lower shell and an upper cover, a receiving cavity is formed between the lower shell and the upper cover, and a bolt is disposed on the upper cover in a penetrating manner.

[0006] Document DE 10 2016 203 125 A discloses an electromechanical switching device comprising a housing having at least two power terminals and at least two control terminals, at least one switching unit arranged in the housing, which has two switching terminals, wherein the switching unit has an electromechanical switching element connected to the switching terminals for alternately establishing and interrupting an electrical connection between the first and the second switching terminals. The housing has, on an outer side of a housing wall, a contact surface for thermally coupling a heat sink external to the housing, and, on an inner side of the housing wall opposite the outer side, a heat-conducting element for conducting heat from the switching unit and / or the actuator to the contact surface inside the housing.

[0007] The object of the present invention is therefore to provide a contactor with which tolerance-related changes in the installation position can be better compensated. Furthermore, the object of the present invention is to provide a high-voltage box with such a contactor, a method for mounting such a contactor in a high-voltage box, and also a vehicle, in particular an electric vehicle, with such a high-voltage box.

[0008] These objects are achieved by the independent and subordinate patent claims. Further advantageous embodiments are the subject of the dependent claims.

[0009] According to a first aspect of the present invention, a contactor is provided. The contactor has a contactor housing and an electrical contact section arranged on a first housing side for electrically connecting or contacting the contactor with a busbar of a high-voltage (vehicle electrical system) architecture. The busbar, also known as a busbar, is a rigid and high-current-carrying electrical conductor, usually in the form of a rail, which is used to transmit high currents, for example, in a high-voltage vehicle electrical system architecture of an electric vehicle. The busbar has a higher current-carrying capacity than flexible conductors (e.g., cables), which is why it is used in the high-voltage vehicle electrical system architecture as a preferred component for conducting high currents. In the contactor according to the invention, the electrical contact section is designed for electrically connecting to or contacting such a busbar.The electrical contact section further has a first contact surface for contacting a surface section of the busbar. The surface contact ensures the high current-carrying capacity at the transfer point between the electrical contact section and the busbar, since there is low contact resistance due to the surface contact. The first contact surface of the contact section is arranged substantially perpendicular to the first housing side or protrudes substantially perpendicularly from the first housing side. The electrical contact section has a first elongated hole for the passage of a first fastening means for connecting the first contact surface to the surface section of the busbar. The first elongated hole is arranged such that the first fastening means, which can be passed through the first elongated hole, can be displaced in a direction perpendicular to the first housing side.The contactor according to the invention further comprises a housing fastening section arranged on a second housing side for fastening the contactor housing to a bearing section of a high-voltage box having the busbar. The high-voltage box can be part of a high-voltage (on-board electrical system) architecture of an electric vehicle and, in addition to high-voltage components, also comprises one or more busbars which, among other things, serve to conduct the currents to and from the high-voltage components. The housing fastening section has a second contact surface for contacting the bearing section, wherein the second contact surface is arranged substantially perpendicular to the second housing side or protrudes substantially perpendicularly therefrom. The housing fastening section has a second elongated hole for passing through a second fastening means for connecting the second contact surface to the bearing section.The second elongated hole is arranged such that the second fastening means, which can be passed through the second elongated hole, can be displaced in a direction perpendicular to the first housing side. In the contactor according to the invention, in a viewing direction perpendicular to the second housing side, the second contact surface forms an angle with the first contact surface that lies in a range from greater than 0° to less than 90°. In other words, when viewed perpendicular to the second housing side, the housing fastening section is arranged "twisted" or "skewed," so that the two contact surfaces are neither perpendicular nor parallel to each other.

[0010] The present invention is based, at least in part, on the realization that the installation position of the contactor in a high-voltage architecture is usually predetermined. However, this installation position is subject to tolerances, as is the contactor itself. If – as mentioned above – high-current carrying capacity is to be ensured, the contactor must be installed as accurately as possible in its installation position. However, dimensional and / or manufacturing tolerances can lead to improper installation of the contactor. This can result in stresses acting on the contactor during installation and subsequent securing, which can impair its functionality, particularly its function as a safety shutdown device.For example, contactors typically have ceramic elements inside which break when exposed to excessive voltages, such as those that may occur if the contactor is not installed optimally, and thus impair the contactor's functionality.

[0011] The present invention is based on the discovery that, by means of two elongated holes extending perpendicular to the first housing side and two contact surfaces arranged neither perpendicular nor parallel to each other, a slight displacement of the contactor in a direction perpendicular to the first housing side results in the contactor not only being moved perpendicular to the first housing side, but also being able to move somewhat parallel to the first housing side. This allows both longitudinal and vertical tolerances in the installation position of the contactor to be overcome. The contactor can be installed in the position best suited for its functional activity and then securely fixed in place without impairing its functionality.

[0012] Preferably, the first housing side and the second housing side are perpendicular to each other. For example, the first housing side is a front or rear side of the housing, and the second housing side is a side surface of the housing. Thus, for example, the electrical contact section protrudes forward, while the housing fastening section protrudes to the side.

[0013] Preferably, the angle formed by the second contact surface with the first contact surface is in a range of approximately 10° to approximately 45°. This angle range has proven particularly advantageous in practice, as it allows for sufficiently high installation tolerances to be compensated and, in addition, the fastening means can be mounted along the axis of the fastening means using a (machine-assisted) tool. In particular, the second fastening means (which is guided through the "twisted" housing fastening section) can also be operated using a (machine-assisted) tool.

[0014] Preferably, the two elongated holes are dimensioned such that the fastening means passing through the respective elongated hole can be displaced by at least 3 mm, preferably at least 5 mm, and more preferably at least 1 cm, in a direction perpendicular to the first housing side. This allows the contactor to be mounted in installation positions that would otherwise be inaccessible.

[0015] According to a second aspect of the present invention, a high-voltage box is provided, comprising: a high-voltage box housing with a bearing section, a high-voltage component arranged in the high-voltage box housing, a busbar electrically connected in the high-voltage box housing and to the high-voltage component, and a contactor according to the first aspect or embodiments thereof, wherein the electrical contact section of the contactor is connectable or connected to the busbar of the high-voltage box by means of the first fastening means and the housing fastening section of the contactor is connectable or connected to the bearing section of the high-voltage box by means of the second fastening means.

[0016] Preferably, when the contactor is mounted, the first contact surface has a surface contact with the busbar, and the second contact surface has approximately at least a line contact with the bearing section. This ensures surface contact at least at the electrical contact section, and thus the required high-current carrying capacity.

[0017] Preferably, the bearing section of the high-voltage box forms an angle with the busbar, which can be the same as the angle between the first and second contact surfaces, and the second contact surface of the housing mounting section also forms a surface contact with the bearing section of the high-voltage box. In this embodiment, surface contacts are present on both the electrical contact section and the housing mounting section. This enables more stable mounting of the contactor in the high-voltage box.

[0018] According to a third aspect of the present invention, a method for mounting a contactor according to the first aspect or embodiments thereof in a high-voltage box according to the second aspect or embodiments thereof is provided, wherein the method comprises the following steps: introducing the contactor into the high-voltage box housing such that the electrical contact section contacts the busbar over a large area, displacing the contactor in a direction perpendicular to the first housing side until the second contact surface of the housing fastening section has at least one line contact, preferably surface contact, with the bearing section of the high-voltage box housing, and fixing the position by inserting the first and / or second fastening means through the respective elongated hole in the electrical contact section or the housing fastening section for fastening the contactor in the high-voltage box.If the fasteners are screws, the screws can, for example, be passed through the respective elongated holes and screwed into (blind) holes provided for the fasteners.

[0019] Preferably, in the method according to the invention, the fastening means are first loosely inserted, then the contactor is aligned or moved until the housing fastening section has at least one line contact, preferably surface contact, with the bearing section of the high-voltage box housing, and then the fastening means are tightened to fix the contactor in the aligned position.

[0020] According to a fourth aspect of the present invention, a vehicle, in particular an electric vehicle, is provided with a high-voltage box according to the third aspect or embodiments thereof.

[0021] Preferably, in the vehicle according to the invention, the contactor of the high-voltage box is connected to a DC charging line of the vehicle.

[0022] Further features and objects of the present invention will become apparent to those skilled in the art upon application of the present teachings and upon consideration of the accompanying drawings. Fig. 1 a schematic view of a contactor according to the invention in a high-voltage box according to the invention, Fig. 2 a schematic view of the shooter of Fig. 1 in the installation position, Fig. 3 a further schematic view of the contactor according to the invention in a further high-voltage box according to the invention, Fig. 4 a schematic view of the shooter of Fig. 3 in the installation position, and Fig. 5 a schematic perspective view of the contactor according to the invention.

[0023] Elements of the same construction or function are provided with the same reference symbols throughout the figures.

[0024] It is initially Fig. 1, which shows a schematic view of a contactor 10 in a high-voltage box 12. The high-voltage box 12 can be part of a high-voltage (on-board network) architecture of an electric vehicle. The high-voltage box 12 serves, among other things, to conduct currents and / or voltages, to convert current / voltage, and to perform other electrical functions required for electric vehicles, e.g., during charging / propulsion. The high-voltage box 12 can have a high-voltage box housing, which is Fig. 1 is shown schematically as a black box. The high-voltage box 12 has at least one high-voltage component 14. The high-voltage component 14 can be a DCDC, an inverter, a PFC, or any other suitable high-voltage component 14. High-voltage components such as component 14 are usually connected to busbars to distribute / conduct any high currents that may occur within the high-voltage (vehicle electrical system) architecture. An example is shown in Fig. 1 shows a busbar 16 that is electrically connected to the high-voltage component 14. The electrical connection can be of any suitable nature, for example, by means of a package, PCB, directly wired, or otherwise. The busbar 16 is a plate-shaped rigid body and has a flat, usually planar surface. The busbar 16 is usually thermally connected to a heat sink (not shown) of the high-voltage box 12 via a thermal paste or the like (generally referred to as TIM). The high-voltage box 12 further has a bearing section 18 for supporting the contactor 10. The bearing section 18 can have a bore into which a fastening means for attaching the contactor 10 to the bearing section 18 can be screwed or otherwise inserted.

[0025] The contactor 10 has a contactor housing 20. The contactor housing 20 is schematically indicated as a rectangular box, but can have a different, particularly more differentiated, design. On a first housing side 22, the contactor 10 has an electrical contact section 24, which is also essentially plate-shaped and protrudes perpendicularly from the first housing side 22. The electrical contact section 24 has a first elongated hole 26 through which a further fastening means 28 can be passed.

[0026] The first elongated hole 26 extends substantially perpendicular to the first housing side 22 and enables the displacement of the fastening means 28 in a direction perpendicular to the first housing side 22. The electrical contact section 24 serves to electrically connect and / or contact the contactor 10 with the busbar 16. Due to the high currents to be expected, a surface contact is preferable, as this reduces the contact resistance and ensures the high current carrying capacity. The electrical contact section 24 has a first contact surface 30 for this purpose. The first contact surface 30 should ideally contact the busbar 16 over a surface area, as shown schematically in Fig. 1. The first contact surface 30 can be an underside of the electrical contact section 24. Since the electrical contact section 24 protrudes perpendicularly from the first housing side 22, the first contact surface also extends substantially perpendicularly to the first housing side 22. The term "substantially" is intended to express that, within narrow tolerances, which may be manufacturing and / or material-related, the contact section 24 protrudes perpendicularly from the first housing side 22.

[0027] The contactor 10 further has a second housing side 32, which in the present example is perpendicular to the first housing side 22. For example, the first housing side 22 can be a front or rear side, and the second housing side 32 can be a side surface of the contactor housing 20; but this does not necessarily have to be the case.

[0028] A housing fastening section 34 extends essentially perpendicularly from the second housing side 32. The housing fastening section 34 serves to fasten the contactor housing 20 to the bearing section 18 of the high-voltage box 12. The fastening is intended to prevent the contactor 10 from moving within the high-voltage box 12. Inside the contactor 10 are, among other things, ceramic elements that can break. For this and other reasons, a secure and stationary fixation is essential. The housing fastening section 34 also has an elongated hole (second elongated hole) 36. Another (second) fastening means can extend through this elongated hole (see Fig. 2). The second elongated hole 36 is arranged such that this second fastening means is displaceable in a direction perpendicular to the first housing side 22. The second fastening means does not have to be arranged vertically, but could be arranged vertically. The second fastening means can be passed through the second elongated hole 36 and fastened, for example, in the bearing section 18. If the second fastening means is a screw, the bearing section 18 can have a (threaded) bore so that the screw can be screwed therein. Similarly, the first fastening means 28 can also be a screw and can be screwed into a (threaded) bore below the current collecting bar 16.

[0029] The housing mounting portion 34 has a second contact surface 38, which serves to contact a surface of the bearing portion 18. The second contact surface 38 can be an underside of the housing mounting portion 34 and, as such, protrude substantially perpendicularly from the second housing side 32.

[0030] As in Fig. 1 is shown schematically in an exaggerated manner, in the event of surface contact between the first contact surface 30 and the busbar 16, a small gap 40 could exist between the bearing section 18 and the second contact surface 38 due to manufacturing and / or material tolerances. If the contactor housing 20 were to be fastened to the bearing section 18, the following things could happen, among others: (Bending / torsional) stresses could be introduced into the contactor housing 20 and thus into the contactor 10. The busbar 16 could bend slightly and possibly detach from the TIM. Both of these should be avoided if possible to ensure the functioning of the contactor 10 and / or the busbar 16.

[0031] In the contactor 10 according to the invention, the housing mounting section 24 is therefore arranged slightly rotated, so that the second contact surface 38 and the first contact surface 30 enclose an (inner) angle 42 of more than 0° and less than 90°. In other words, the second contact surface should be arranged so as to slope upwards / downwards and should not run parallel or perpendicular to the first contact surface 30. This arrangement can compensate for a height difference between the positions at which the busbar 16 and the bearing section 18 are to be contacted.

[0032] It is now on Fig. 2, which schematically shows a final installation position of the contactor 10. In comparison with the Fig. 1, the contactor 10 has been moved slightly to the left (generally: perpendicular to the first housing side 22), which is indicated by the arrow 44. Due to the movement of the contactor 10 to the left in the direction perpendicular to the first housing side 22, the first fastening means 28 moves to the right in the elongated hole 26, which is indicated by the arrow 46. At the same time, the housing fastening section 34 also moves to the left in the direction perpendicular to the first housing side 22 until the second contact surface 38 makes at least linear contact with the bearing section 18. If a second fastening means 39 were now passed through the second elongated hole 36 and fastened to the bearing section 18 (e.g., by screwing), no (bending / torsional) stresses would occur in the contactor housing 20 or in the busbar 16.The special arrangement of the second and first contact surfaces 38, 30 thus makes it possible to compensate for height and / or length tolerances without the contactor housing 20 and thus the contactor 10, or the busbar 16 being live when the contactor 10 is mounted in the high-voltage box 12.

[0033] The angle 42 formed by the second contact surface 38 and the first contact surface 30 ideally lies in a range of 10° to approximately 45°. This angle range has proven particularly advantageous, especially since it also allows for machine-assisted screwing / fastening of the second fastening means 39 from above.

[0034] It is now on Fig. 3, which shows a schematic view of another embodiment of the high-voltage box 12 with the contactor 10. In contrast to the high-voltage box 12 of Fig. 1 and Fig. 2, is in the high-voltage box 12 of Fig. 3, the bearing section 18 is also arranged at an angle. The bearing section 18 can enclose an (inner) angle with the busbar 16, which essentially corresponds to the angle 42 between the first and second contact surfaces 30, 38. Here, too, a gap 40 would initially exist between the second contact surface 38 and the bearing section 18, assuming dimensional tolerances were again assumed. However, as in Fig. 4, when the contactor 10 is moved to the left and in a direction perpendicular to the first housing side 22 (see arrow 44), both the electrical contact section 24 and the housing fastening section 34 would be moved to the left until the second contact surface 38 contacts the bearing section 18. In contrast to the example shown in Fig. 1 and Fig. 2 is the contact between the second contact surface 38 and the bearing section 18 in the example of Fig. 4, however, is a surface contact. The surface contact leads to increased stability when attaching the contactor 10 in the high-voltage box 12.

[0035] The angle 42, which the second contact surface 38 encloses with the first contact surface 30, is in turn in a range of 10° to approximately 45°, so that access to the second fastening means 39 is possible, in particular when - as in the specific example of Fig. 4 - the inclined fastening means 39 would have to be operated from above by means of a tool, possibly mechanically assisted.

[0036] It is now on Fig. 5, which shows a schematic perspective view of the contactor 10. The contactor 10 has the contactor housing 20, on whose first housing side 22, in the specific example, two electrical contact sections 24 are arranged. The housing fastening section 34 is arranged on the second housing side 32. Another comparable housing fastening section can be arranged on a side opposite the second housing side 32. The elongated holes 26, 36 enable the contactor 10 to be displaced in a direction perpendicular to the first housing side 22 while simultaneously compensating for any possible height offset between the busbar and the bearing section. A displacement path of at least 3 mm, preferably at least 5 mm, more preferably at least 1 cm is possible. This displacement path and a height offset resulting depending on the angle 42 are typically within the range of manufacturing tolerances of the high-voltage box 12 and the contactor 10.

[0037] The assembly or installation of the contactor 10 in the high-voltage box 12 can be carried out as follows: 1. The contactor 10 is inserted into the high-voltage box 12. The first contact surface 30 contacts, ideally flat, the busbar 16. In this position, the second contact surface 38 may not contact the bearing section 18 or may not contact it in an ideal manner. 2. The contactor 10 is moved in a direction perpendicular to the first housing side 22 until the second contact surface 38 contacts the bearing section, either by means of line contact (see Fig. 2) or by surface contact (see Fig. 4). The ideally flat contact between the first contact surface 30 and the busbar 16 remains. 3. In the “shifted” position (final installation position), the contactor 10 can then be fixed, for example by using the fastening means 28, 39.

[0038] The contactor 10 or the high-voltage box 12 can be used in a vehicle, in particular in an electric vehicle. In particular, the contactor 12 can be arranged in a DC charging line or a DC charging port of the vehicle and can "open" or "close" the charging line or charging port as needed. For example, the port is closed when a charging cable from a charging station for charging the electric vehicle's battery is connected to the vehicle. For example, the port is opened or interrupted when the charging cable is removed. Other cases are conceivable in which the contactor 10 opens or closes the port. Of course, other areas of application and / or other purposes for the contactor 10 are conceivable.
