[0001] The present invention relates to an apparatus having a first component and a second component, the first component having at least one first electrical connector and a second electrical connector, the second component having at least one first electrical mating connector and a second electrical mating connector, wherein the connecting surface of the first connector is electrically connected to the first mating connector, wherein the second connector is electrically connected to the second mating connector, and wherein the first connector and the second connector are arranged sequentially such that at least one straight line oriented perpendicular to the connecting surface of the first connector extends not only through the first connector but also through the second connector.

[0002] Furthermore, the present invention relates to a bite engagement mechanism for manufacturing such a device.

[0003] Furthermore, the present invention relates to a system having a first component, a second component, and such a bite engagement mechanism. Background Technology

[0004] To electrically connect two components, each component typically has one or more electrical connectors. Devices having a first component and a second component are known, particularly from motor vehicle constructions, wherein the first component has at least one first electrical connector and a second electrical connector, and the second component has at least one first electrical mating connector and a second electrical mating connector. Here, the connecting surface of the first connector is electrically connected to the first mating connector, and the second connector is electrically connected to the second mating connector.

[0005] Typically, the first and second connectors are arranged sequentially such that at least one straight line oriented perpendicular to the connection surface of the first connector extends through both the first and second connectors. This arrangement of connectors is typical, for example, if the first component refers to the pressure-generating unit of a hydraulic assembly for a braking device. Because the first and second connectors are arranged sequentially, they are difficult to access, thus making connection with mating connectors difficult. Summary of the Invention

[0006] The device according to the invention has the advantage of particularly high stability in the connection between the connector and the mating connector. Furthermore, it offers advantages in manufacturing the device, namely, the ability to establish the connection between the connector and the mating connector particularly quickly. For this purpose, according to the invention, the connector and the mating connector are connected to each other by means of a bite joint. In a bite joint (also known as a riveting or toxen), the connection between the connector and the mating connector is achieved by means of a presses and a die. In this respect, the bite joint provides a form-locking connection between the connector and the mating connector. This is particularly stable mechanically. Because the connector of the first component is difficult to access, bite joints have been avoided in the prior art when manufacturing devices of the type described at the beginning. Instead, it is known to connect the connector and the mating connector to each other by resistance welding. The connectors are arranged sequentially such that at least one straight line oriented perpendicular to the connecting surface of the first connector extends not only through the first connector but also through the second connector. This relates to the design or shape of the connecting surface before it is connected to the first mating connector. Preferably, the connecting surface before it is connected to the first mating connector refers to the connecting plane. Preferably, the first mating connector has a connecting mating surface, through which the first mating connector is connected to the connecting surface of the first connector. Particularly preferably, the second connector also has a connecting surface, wherein this connecting surface is connected to the connecting mating surface of the second mating connector. Hereinafter, the connecting surface of the first connector is also referred to as the first connecting surface, and the connecting surface of the second connector is also referred to as the second connecting surface, and the connecting mating surface of the first mating connector is also referred to as the first connecting mating surface, and the connecting mating surface of the second mating connector is also referred to as the second connecting mating surface.

[0007] According to a preferred embodiment, the minimum distance between the first connector and the second connector is between 7 and 11 mm, particularly preferably 9 mm. By arranging the second connector so close to the first connector, a space-saving design for the first component can be achieved. However, the connector is particularly difficult to access in the manufacture of the device.

[0008] According to a preferred embodiment, the first component is a pressure generating unit for a hydraulic assembly of a braking device, and the second component is a controller for the pressure generating unit. This pressure generating unit typically includes an electric motor. Preferably, these connectors are electrically connected to the electric motor, and mating connectors are electrically connected to the power electronics of the controller. The electric motor is thus correspondingly electrically connected to the power electronics via the connectors and mating connectors.

[0009] According to a preferred embodiment, the first component has a third electrical connector, wherein the first and third connectors are arranged sequentially such that at least one straight line oriented perpendicular to the connection surface of the first connector extends through both the first and third connectors. The second component has a third electrical mating connector, and the third connector and the third mating connector are interconnected by a snap-fit ​​joint. Because the first and third connectors are also arranged sequentially, the third connector is also difficult to access for connection to the third mating connector. In particular, the three connectors are electrically connected to different phases of the motor windings of the electric motor. The sequential arrangement of the connectors provides a compact connection structure for electrical contact with the electric motor.

[0010] Preferably, the connectors are arranged sequentially along a circular trajectory. This achieves a simple electrical connection between the connectors and the phases of the motor windings. The motor windings are also typically arranged along a circular trajectory around a rotatably supported rotor of the electric motor. Preferably, the first connector is oriented such that the tangent to the point in the first connection surface that touches the circular trajectory is perpendicular to the first connection surface. The same applies preferably to the second and third connectors.

[0011] Preferably, the joint and / or mating joint are constructed in the form of a sheet metal. The joint and the mating joint can then be connected to each other, particularly advantageously, by means of a bite-locking joint. Here, the sheet metal shape is understood as a shape whose width and length are significantly greater than its thickness. For example, if the first joint is constructed in the form of a sheet metal, then the first connecting surface is defined by the width and length of the sheet metal shape.

[0012] According to a preferred embodiment, the first component has a housing plate from which a connector extends in the same direction. This also achieves a particularly compact design of the connection mechanism formed by the connector. The housing plate is part of the housing of the first component. Preferably, the electric motor is arranged in the interior space of the housing. Preferably, the connector penetrates the recess of the housing plate such that at least one section of the connector is located outside the interior space of the housing. Therefore, the ends of the phases of the motor windings to be contacted extend from the interior space through the connector.

[0013] The bite-fit mechanism according to the invention for manufacturing the device according to the invention has a mattize and a stempel, wherein the mattize has a mating recess, and the stempel is supported in a manner movable along a drive axis and has a stempel surface axially opposite the mating recess about the drive axis, such that the stempel surface can be conveyed to the mating recess by movement of the stempel to connect electrical connectors arranged between the mating recess and the stempel surface to each other by bite-fit, and wherein the longitudinal central axis of the substrate and the center of the stempel surface are radially offset from each other about the drive axis. The bite-fit mechanism according to the invention refers to a bite-fit mechanism for manufacturing the device according to the invention. In this respect, the bite-fit mechanism according to the invention is configured to connect the joints and mating joints of the components of the device to each other by bite-fit. As described above, due to its arrangement, the joints are difficult to access. Because the longitudinal central axis of the substrate and the center of the stempel surface are radially offset from each other, the stempel surface can still be arranged between the first joint and the second joint to connect the first joint or the second joint to the corresponding mating joint by bite-fit. The arrangement of the male mold base between the first and second joints is not necessary for the connection between the joints and mating joints via a bite joint. The longitudinal central axis of the base should be understood as an axis parallel to the drive axis and extending through the center of the base.

[0014] Preferably, the base and the male mold surface are radially spaced apart from each other. Therefore, there is no straight line parallel to the drive axis that extends through both the base and the male mold surface. Due to the radial spacing between the base and the male mold surface, the male mold surface can be arranged particularly easily between the first and second joints.

[0015] Preferably, the male die has a punch with a male die face. Therefore, the male die has at least a base and a punch. By providing the punch, the male die is constructed to be mechanically stable despite the male die face being radially spaced from the base. Preferably, the punch is arranged on the outer peripheral wall of the base, and particularly preferably in the region of the base facing the free end of the female die.

[0016] According to a preferred embodiment, the punch has an axial extension range of less than 11 mm, particularly preferably less than 9 mm. Thus, the punch can generally be easily arranged between the first and second joints.

[0017] According to a preferred embodiment, the female mold has a fixing section through which it is fixed to the female mold carrier of the bite-fitting mechanism, wherein the fixing section and the engagement recess are radially offset from each other. With this design of the bite-fitting mechanism, the engagement recess can also be easily arranged between two sequentially arranged joints of the first member.

[0018] The system according to the invention has a first component and a second component, wherein the first component has at least one first electrical connector and a second electrical connector, wherein the first and second connectors are arranged sequentially such that at least one straight line oriented perpendicular to the connection surface of the first connector extends not only through the first connector but also through the second connector, and wherein the second component has at least one first electrical mating connector and a second electrical mating connector. The system according to the invention is characterized by a bite-fit mechanism according to the invention, wherein the bite-fit mechanism is configured to connect the connector to the mating connector by means of bite-fit. Preferably, the punch of the bite-fit mechanism is form-fitted onto the first component such that the axial extension of the punch is less than the minimum distance between the first and second connectors. Preferably, the features described for the first and second components of the aforementioned reference device are also implemented in the first or second component of the system. Attached Figure Description

[0019] The invention will now be explained in detail with reference to the accompanying drawings. For this purpose, it is shown that: Figure 1 An apparatus having a first component and a second component is shown. Figure 2 A detailed view of the first component is shown, and Figure 3 The bite-joint mechanism used in manufacturing this device is shown. Detailed Implementation

[0020] Figure 1 The device 1 is shown in the schematic diagram. The device 1 has a first component 2 and a second component 3.

[0021] The first component 2 refers to the pressure generating unit 2 of the hydraulic assembly used in the braking device. The first component 2 has an electric motor 4, which has a rotatably supported rotor and multi-phase motor windings. Furthermore, the first component 2 has a first electrical connector 5, a second electrical connector 6, and a third electrical connector 7. Connectors 5, 6, and 7 are respectively electrically connected to another phase of the motor windings.

[0022] The second component 3 refers to the controller 3 used in the hydraulic assembly, or pressure generating unit 2. The controller 3 has a power electronic device 8 with multiple switching elements. In addition, the second component 3 has a first electrical mating connector 9, a second electrical mating connector 10, and a third electrical mating connector 11. The mating connectors 9, 10, and 11 are respectively electrically connected to the other half of the bridge of the power electronic device 8.

[0023] The first connector 5 is electrically connected to the first mating connector 9. The second connector 6 is electrically connected to the second mating connector 10. The third connector 7 is electrically connected to the third mating connector 11. Connectors 5, 6, and 7 are connected to mating connectors 9, 10, and 11 by means of a form-locking engagement. Therefore, the connection between connectors 5, 6, and 7 and mating connectors 6, 10, and 11 is provided at least partially by form-locking.

[0024] Figure 2 A detailed view of the first component 2 is shown. The first component 2 is... Figure 2 The first component 2 is shown before the connection of the second component 3. For this purpose, the first component 2 for the device 1 is shown. The first component 2 has a housing 12 with a housing plate 13, wherein the electric motor 4 is arranged in the internal space of the housing 12. Here, the housing 12 refers to an aluminum housing 12. Connectors 5, 6, and 7 pass through the recesses of the housing plate 13 and protrude from the internal space of the housing 12 to enable contact with the electric motor 4 arranged within the housing 12. Connectors 5, 6, and 7 protrude from the housing plate 13 in the same direction. Connectors 5, 6, and 7 are rigidly connected to the housing plate 13.

[0025] The design of the first connector 5 is explained in detail below. However, connectors 5, 6, and 7 are constructed identically, and thus the structural features described for the first connector 5 are also implemented for the second connector 6 and the third connector 7. The first connector 5 is constructed as a plate. In this respect, the width b and length of the first connector 5 are significantly greater than the thickness d of the first connector 5. This length extends perpendicular to the housing plate 13 and is perpendicular to... Figure 2 The diagram extends in the plane, thus this length is... Figure 2 It is not visible in the middle.

[0026] The width b and length of the first connector 5 define a first connecting surface 14A. The first connecting surface 14A is understood as the surface of the first connector 5 provided for connection with the first mating connector 9 by means of a bite engagement. Accordingly, the second connector 6 and the third connector 7 have a second connecting surface 14B or a third connecting surface 14C.

[0027] If connectors 5, 6, and 7 are connected to mating connectors 9, 10, and 11, such that components 2 and 3 constitute device 1, then the first connector 5 is connected to the first mating connector 9 via the first connecting surface 14A. The second connector 6 is then connected to the second mating connector 10 via the second connecting surface 14B. The third connector 7 is connected to the third mating connector 11 via the third connecting surface 14C.

[0028] Preferably, the mating joints 9, 10 and 11 are also constructed as plates, so that each of the mating joints 9, 10 and 11 has a mating surface.

[0029] Connectors 5 and 6 are arranged sequentially such that at least one straight line 15, oriented perpendicular to the first connecting surface 14A, extends through not only the first connector 5 but also the second connector 6. Connectors 5 and 7 are arranged sequentially such that at least one straight line, oriented perpendicular to the first connecting surface 14A, extends through not only the first connector 5 but also the third connector 7. Here, the straight line 15 also passes through the third connector 7 and thus extends through the first connector 5, the second connector 6, and the third connector 7.

[0030] Here, connectors 5, 6, and 7 are arranged sequentially along a circular trajectory 16. The circular trajectory 16 extends through the centers of connectors 5, 6, and 7, respectively. The first connector 5 is oriented such that the tangent 17 of the point on the circular trajectory 16 located in the first connecting surface 14A is perpendicular to the first connecting surface 14A. The same applies to the orientation of the second connector 6 and the third connector 7, or the orientation of the second connecting surface 14B and the third connecting surface 14C.

[0031] The minimum spacing 18 between the first connector 5 and the second connector 6 is approximately 9 mm, which is exactly 8.88 mm in this case. The minimum spacing 19 between the first connector 5 and the third connector 7 is also approximately 9 mm, which is exactly 8.88 mm in this case.

[0032] Preferably, the second member 3 also has a housing with a shell plate from which mating joints 9, 10, and 11 extend in the same direction, wherein the mating joints 9, 10, and 11 are fixedly and rigidly connected to the housing of the second member 3. The mating joints 9, 10, and 11 thus correspond substantially in their arrangement to joints 5, 6, and 7, such that joints 5, 6, and 7 can easily come into contact with mating joints 9, 10, and 11, so that joints 5, 6, and 7 are connected to mating joints 9, 10, and 11 by means of a bite engagement.

[0033] According to another embodiment, mating connectors 9, 10, and 11 are each connected to the housing of the second component 3 via another cable. The mating connectors 9, 10, and 11 are thus flexibly connected to the housing of the second component 3, such that the orientation of the mating connectors 9, 10, and 11 relative to the housing of the second component 3 is changeable.

[0034] Because connectors 5, 6, and 7 are arranged sequentially and the minimum spacing 18 and 19 between them is very small, connectors 5, 6, and 7 are difficult to access, especially for interlocking joints. See below. Figure 3 Describes an advantageous bite engagement mechanism 20 for connecting connectors 5, 6 and 7 with mating connectors 9, 10 and 11.

[0035] The bite engagement mechanism 20 has a carrier 21. In addition, the bite engagement mechanism 20 has a male mold 22, which is movably supported on the carrier 21 along the drive axis 23.

[0036] The male die 22 has an elongated base 24 and a punch 25 disposed on the base 24. The base 24 has a longitudinal central axis 26 extending parallel to the drive axis 23. The punch 25 has a male die surface 27.

[0037] The punch 25 is arranged on the base 24 such that the longitudinal central axis 26 and the center 28 of the male die surface 27 are radially offset from each other about the drive axis 23. Here, the punch 25 is arranged on the base 24 such that the base 24 and the punch 25 are radially adjacent to each other. This results in the male die surface 27 and the base 24 being radially spaced apart.

[0038] Furthermore, the interlocking mechanism 20 has a female mold 29. The female mold 29 has a fixing section 30 through which the female mold 29 is fixed to the carrier 21. The carrier 21 thus forms the female mold carrier 21. The fixing section 30 is axially opposite to the base 24 of the male mold 22 about the drive axis 23.

[0039] Furthermore, the female mold 29 has a mating recess 31. The mating recess 31 is axially opposite to the male mold surface 27 about the drive axis 23. In this respect, the male mold surface 27 can be conveyed to the mating recess 31 by moving the male mold 22 along the drive axis 23 so that the electrical connectors arranged between the mating recess 31 and the male mold surface 27 can be interconnected by means of a snap-fit ​​engagement. Because the mating recess 31 is axially opposite to the male mold surface 27, the fixed section 30 and the mating recess 31 are radially offset from each other.

[0040] The bite engagement mechanism 20 is configured to fit the members 2 and 3 in such a way that the joints 5, 6, and 7 can be connected to the mating joints 9, 10, and 11 by means of the bite engagement mechanism 20. For this purpose, the punch 25 has an axial extension 32 smaller than the minimum spacing 18 and 19. The die 29 also has an axial extension 33 smaller than the minimum spacing 18 and 19.

[0041] If the first connector 5 is to be connected to the first mating connector 9 by means of the interlocking mechanism 20, the second member 3 is arranged on the first member 2 such that the first connecting surface 14A is flat against the connecting mating surface of the first mating connector 9. Furthermore, members 2 and 3 are arranged such that the first connector 5 and the first mating connector 9 are positioned between the male die surface 27 and the mating recess 31. Therefore, the punch 25 and the female die 29 thus surround the first connector 5 and the first mating connector 9.

[0042] The first component 2, the second component 3, and the bite engagement mechanism 20 are arranged, for example, such that the female die 29 is located in region 32 between the first joint 5 and the second joint 6, and the punch 25 is located in region 33 between the first joint 5 and the third joint 7. Alternatively, the first component 2, the second component 3, and the bite engagement mechanism 20 are arranged such that the female die 29 is located in region 33, and the punch 25 is located in region 32. In order to connect the first joint 5 and the first mating joint 9 by means of bite engagement, the male die surface 27 is conveyed to the engagement recess 31 such that the joint 5 and the first mating joint 9 are deformed between the male die surface 27 and the engagement recess 31 and thereby connected.

[0043] Because of the radial offset between the base 24 and the male mold surface 27, the base 24 does not need to be arranged between the first joint 5 and the second joint 6, or between the first joint 5 and the third joint 7. Instead, the base 24 is arranged in region 34, region 35, region 36, or region 37. Therefore, when the first joint 5 is connected to the first mating joint 9, the base 24 is not located between the first joint 5 and the second joint 6, nor between the first joint 5 and the third joint 7. Instead, the base 24 is radially arranged about the circular trajectory 16 outside of joints 5, 6, and 7, or radially arranged within joints 5, 6, and 7.
