Description

ONBOARD POWER SYSTEM CONNECTOR TECHNICAL FIELD OF THE INVENTION The subject matter relates to an on-board power supply connector, specifically for an on-board power supply system in a motor vehicle, particularly a passenger car or truck, or other motorized vehicle. The on-board power supply connector is especially suitable for high-voltage on-board power supply systems. BACKGROUND OF THE INVENTION In automotive applications, there are several types of high-voltage on-board networks. On the one hand, these can be on-board networks with voltages higher than 12V, for example, 24V or 48V. Due to the increasing number of comfort consumers in motor vehicles, the idea that 48V on-board power networks are advantageous is gaining traction; however, these require different plug connections than those needed for conventional 12V on-board networks. On the other hand, a high-voltage on-board network can also be understood as an on-board network for the propulsion system, especially in vehicles powered by electric motors. The propulsion system often operates at voltages of several hundred volts, for example, around 400V.In addition to high voltages, high currents can also be expected in these on-board power systems, since considerably more power is required to drive the motor than to operate comfort appliances. These on-board power systems also place particularly high demands on the connectors. Particularly in highly dynamic automotive applications, high demands are placed on the mechanical stability of on-board power system connectors. On-board connectors must guarantee a consistently stable and electrically reliable connection. Due to the sometimes high currents involved, there are also significant demands on the contact resistance of these connectors to minimize heat loss at the junction. This necessitates large contact surfaces between the connecting elements. To ensure an electrically flawless and permanently stable connection with low contact resistance and high stability against dynamic loads, a MA / a / ZUZJ / UUl / 30 longitudinal and the second connecting part is in mechanical contact with the first connecting part. In this case, the contact surfaces of the connecting parts are in contact with each other. In particular, the contact surfaces are, on the one hand, an outer lateral surface of one connecting part that is in direct contact with an inner lateral surface of another connecting part. To establish a good electrical connection, the contact surfaces must be firmly connected. Furthermore, for dynamic stability, this connection must be secured even in dynamic environments. To achieve this, it is proposed that the first connecting part be spring-mounted to the first housing part along its longitudinal axis by means of a spring element. When the second housing part is connected to the first housing part, the first and second connecting parts come into contact. The coupling of the housing parts results in a pressing force from the second housing part against the first housing part along its longitudinal axis, counteracting the spring force of the spring element. Thus, the spring element is compressed in the connected state, causing a permanent spring force to act on the connection between the two connecting parts.The first connecting part moves longitudinally in the first housing part against the spring force. According to one embodiment, it is proposed that one of the connecting parts be a sleeve-shaped receptacle and another of the connecting parts be a rod-shaped connectable element congruent with the receptacle. The receptacle and the connectable element are preferably arranged in the center of the respective housing parts and each extends in the longitudinal direction. The receptacle and the connectable element are preferably located on the central axis of the respective housing part. The sleeve-shaped receptacle serves to receive the connectable element. An inner side surface of the sleeve-shaped receptacle comes into direct contact with an outer side surface of the connectable element in the connected state. The housing portion, which has the connection point for the sleeve-shaped receptacle, is preferably inserted into the housing portion, which has the connection point for the rod-shaped connectable element. An annular space is formed between the inner side surface of the housing portion and the rod-shaped connectable element. The other housing portion, together with the sleeve-shaped receptacle, is inserted into this annular space. The housing portion with the sleeve-shaped receptacle is inserted into the front opening of the housing portion containing the connectable element. The connectable element is inserted into the front opening of the housing portion with the sleeve-shaped receptacle.The outer surface of the connectable element thus comes into contact with the inner surface of the sleeve-shaped receptacle. It is proposed that, in the connected state, the connectable element is inserted into the receptacle and the spring element is compressed. The spring element is, in particular, a steel spring, preferably a compression spring. However, the spring element can also be made of plastic. The spring element can be resiliently compressed along its longitudinal axis, whereby in the compressed state, the spring element exerts a force on the connecting part, pressing it against the other respective connecting part. Since, in the connected state, the housing parts are fixed together longitudinally, the spring force acts on the contact surface between the two connecting parts. According to one embodiment, it is proposed that in the connected state one of the housing parts is at least partially inserted into the front opening of the other housing part. This insertion brings the sleeve-shaped receptacle and the connectable element into direct contact. The sleeve-shaped receptacle preferably extends into the housing portion longitudinally along its longitudinal axis. The sleeve-shaped receptacle has tubular side walls, a bottom at one end, and an opening at the other. The end-face opening of the sleeve-shaped receptacle is aligned with the end-face opening of the housing portion. The base is preferably closed. The housing portion is shaped to surround the sleeve-shaped receptacle and is therefore also preferably sleeve-shaped with tubular side walls. The rod-shaped connectable element has a longitudinal extension. Within the housing portion in which the rod-shaped connectable element is installed, the connectable element extends longitudinally along the longitudinal axis of the housing portion. Preferably, the connectable element has a tubular outer surface that is congruent with the tubular inner surface of the sleeve-shaped receptacle. The tubular connectable element is surrounded by the housing portion, wherein the side walls of the housing portion, in particular the inner side surface of the housing portion's side walls, extend parallel to the outer side surface of the connectable element. Specifically, the outer side surface of the housing portion containing the connectable element is congruent with an inner side surface of the housing containing the sleeve-shaped receptacle.Therefore, the housing with the sleeve-shaped receptacle can be inserted into the housing with the connectable element, and the housing parts support each other with their inner and outer side surfaces. In the connected state, the first housing part is inserted into the front opening of the second housing part or the second housing part is inserted into the front opening of the first housing part. According to one embodiment, the receptacle is tapered, specifically conical, from a front opening towards the bottom. This tapering of the receptacle leads to a better fit between the connectable element and the receptacle. In particular, the connectable element can be inserted into the receptacle such that the contact surfaces, i.e., the outer side surface of the connectable element and the inner side surface of the receptacle, are in contact with each other in all cases. The tapering, particularly the conical taper, serves as a tolerance compensation, since in the inserted state, direct mechanical contact between the connectable element and the receptacle is always guaranteed. It is also proposed that the connectable element taper towards its end face, in particular, that it taper conically. The connectable element and the receptacle preferably have a congruent shape and, in particular, have tapers that extend congruently to each other, so that the connectable element, when inserted into the receptacle, rests with its outer lateral surface against the inner lateral surface of the receptacle. The spring element results in a contact pressure of the connectable element on the receptacle or vice versa. The spring force acting on the longitudinal axis presses the connectable element and the receptacle against each other in such a way that their contact surfaces are firmly connected. According to one embodiment, it is proposed that, in the connected state, an inner side surface of the receptacle and an outer side surface of the connectable element are in direct contact with each other. This direct contact ensures good electrical conductivity at the junction. Ohmic losses are reduced, particularly due to the large contact areas ensured by the congruent covering surfaces. According to one embodiment, a spacer extends within the receptacle from its bottom to a front opening. The opening in the housing portion extending along the longitudinal axis and the opening in the sleeve-shaped receptacle, also extending along the longitudinal axis, are collinear. The spacer may be positioned on the central axis. Alternatively, the spacer may extend along the longitudinal axis from the base to the outermost opening of the receptacle. The spacer may be rod-shaped. In the sleeve-shaped receptacle, an annular gap is formed between the spacer and the inner lateral surface of the sleeve-shaped receptacle. The spacer ensures that the connectable element can only be inserted to a certain point into the receptacle, preventing an overly tight seal between the receptacle and the connectable element. In order to insert the connectable element into the receptacle, the latter must accommodate the spacer. For this purpose, the connectable element has a recess extending from its end face along its longitudinal axis. The housing portion containing the connectable element also has a receptacle within which the connectable element is arranged. The connectable element also extends along its longitudinal axis. The longitudinal axes of the receptacle in the housing portion and the connectable element are preferably collinear. Within the connectable element, the recess, for example, in the form of a hole, can then be provided on the central axis of the connectable element. The spacer fits into this recess in the installed state. That is, when the connectable element is inserted into the sleeve-shaped receptacle, the spacer is simultaneously pushed into the recess. The recess has a certain depth within the connectable element. A stop for the spacer is formed within the recess, for example, by its base. This ensures that the connectable element is inserted into the sleeve-shaped receptacle only to a certain depth, i.e., until the spacer rests against the stop in the recess. According to one embodiment, the first connecting part is connected to a flexible cable. The first connecting part is spring-mounted on the spring element and can be translated within the housing part along the longitudinal axis. To avoid unduly affecting the translational capacity of the cable connected to the connecting part, the flexible cable is either inserted into the first housing part through a bushing and movably mounted in the bushing along the longitudinal axis, or the first connecting part extends from the housing part through a bushing and is movably mounted in the bushing along the longitudinal axis. In particular, the bushing has a longitudinal extension along a longitudinal axis parallel to, and preferably collinear with, the longitudinal axis of the housing part or the receptacle.The bushing preferably extends parallel to the longitudinal axis, so that the movement of the connecting part against the spring element along the longitudinal axis is not impeded by the movement of the cable or the connecting part within the bushing. The direction of movement of the cable or the connecting part within the bushing is preferably parallel to the direction of movement of the connecting part within the housing against the spring element. According to one embodiment, the first connecting part is supported by an inwardly directed radial collar in the front opening of the housing part. This collar preferably preloads the spring element. The spring element is hinged to the connecting part so that it exerts a spring force on the connecting part in the direction of the end-face opening of the housing part. The collar secures or supports the connecting part within the housing part. The spring element can first be inserted into the housing part through the front opening. The connecting part is then pressed against the spring element through the front opening and inserted into the housing part. To secure the connecting part inside the housing element, the collar can be positioned in the front opening of the housing part and locked into it. For this purpose, the collar may have a circumferential side surface that rests against the inner side surface of the housing part's receptacle and locks into it in the installed state. A recess and projection between the collar's side surface and the inner side surface of the housing part may be provided for this purpose. The circumferential side surface of the collar may be arranged in an annular space between the outer side surface of the first connecting part and the inner side surface of the first housing part.The collar secures the connecting part in its translational movement along the longitudinal axis in the direction of the front opening, so that the connecting part is positioned in the first housing section in such a way that it cannot be lost. In the direction towards the bottom of the housing section, the spring element acts on the connecting part, and a force must be applied against the spring force to push the connecting part away from the collar towards the bottom of the first housing section. According to one embodiment, the spring element is supported between a bottom portion of the first housing part and a protrusion, at least partially circumferential and radially outward, of the first connecting part. The first connecting part may have two areas with different outer diameters. In the installed state, the first region faces the front opening of the first housing part and has an outer diameter that approximately matches the inner diameter of the housing part. The second region of the connecting part may have a smaller diameter and thus be configured as a step or recess. The spring element may be disposed in the space formed between the connecting part and the first housing part and may be hinged to the step.In the connected state of the connector, the spring element is compressed and pressed against the protrusion with a spring force parallel to the longitudinal axis, so that the first connectable element is pressed in the direction of the front opening of the first housing part. According to one embodiment, it is proposed that a circumferential seal is disposed on an outer side surface of one of the housing parts, said seal being in contact with an inner side surface of the other of the housing parts in the connected state, or that a circumferential seal is disposed on an inner side surface of one of the housing parts, said seal being in contact with an outer side surface of the other of the housing parts in the connected state, or that a circumferential seal is disposed between an inner side surface of one of the housing parts and an outer side surface of the other of the housing parts.A space that can form between an outer side surface of a first housing part and an inner side surface of the other housing part in the connected state can be sealed by this seal, so that the connection between the sleeve-shaped receptacle and the connectable element is protected against environmental influences. According to one embodiment, the second connecting part is attached to an electrical conductor, particularly a solid conductor, in a material-locking manner. The electrical conductor, particularly a flat conductor, may be stripped at one end or along its length. In the stripped area, the connectable element may be arranged in the form of a bolt on a broad surface of the flat conductor, particularly welded or screwed on. This bolt then serves as the connectable element. It is proposed that the second housing part include a conductor receptacle for receiving the conductor, specifically that the conductor receptacle be continuous and receive the conductor along its propagation direction. The conductor receptacle may have a cover arranged in a hinged manner, specifically in the form of a film hinge, attached to the rest of the housing part. The conductor is inserted into the conductor receptacle, particularly with its stripped area. The conductor insulation is also located within the conductor receptacle area. The conductor receptacle cover can then be placed over the conductor on the opposite side of the conductor from the rest of the second housing part, thus enclosing the conductor receptacle.Seals can be provided around the conductor receptacle in the area of ​​the conductor entries to prevent moisture from entering the receptacle along the conductor's length. The conductor receptacle cover can be securely attached to the rest of the second housing part, particularly by fastening or clipping. Starting from the conductor receptacle, the housing portion preferably extends perpendicular to the conductor's broad surface. In particular, the conductor receptacle extends perpendicular to the longitudinal axis of the second housing portion. The longitudinal axis of the second housing portion and the conductor receptacle, or the conductor inserted into the conductor receptacle, extend at an angle, preferably perpendicular to each other. According to one embodiment, it is proposed that an insulator covering the end face of the second connection part be provided. The second connection part is preferably the connectable element. This connectable element is arranged in the second housing part. For protection against contact, it may be useful to insulate this connectable element at its end face within the housing, thus preventing unintentional contact with the connectable element at its end face. According to one embodiment, the insulator is proposed to have an opening formed to receive the spacer, in particular that the opening is coaxial with the recess of the connectable element. In this way, the insulator provides protection against contact and, at the same time, allows the connectable element and the receptacle with spacer to be connected to each other. According to one embodiment, a locking lever is arranged on one of the housing parts. This lever can be pivoted about an axis perpendicular to the longitudinal axis and, in the connected state, engages with locking means on the other housing part. This ensures that the connecting parts are secured to each other in the longitudinal direction. The housing parts are inserted into each other and secured at least along the longitudinal axis by means of the locking lever and the locking means.

Figure 13 shows a view of an on-board power system connector in the connected state. DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows a first housing part 2 of an on-board power system connector. The housing part 2 extends along a longitudinal axis 4 in the longitudinal direction. The first housing part 2 has an outer side surface 2a and is bounded by an end face 2b. On the side opposite the end face 2b, specifically at a bottom 2c of the first housing part, a flange 6 may project radially from the outer side surface 2a. In the region of the bottom 2c, the housing part 2 has a pass-through opening through which a flexible cable 8 is guided. A circumferential seal 10 can be provided between the end face 2b and the base 2c on the outer lateral surface 2a. A connection part 12 is provided within the housing part 2. The connection part 12 extends into an opening 14 in the end face 2b. The connection part 12 is attached to a collar 16. The connection part 12 can be moved parallel to the longitudinal axis 14 within the housing part 2. A spacer 18, which can be metallic or non-metallic, can be provided within the connection part 12. For mounting the on-board power system connector, for example, in the area MA / a / ZUZJ / UUl of a cable sleeve, a lower body sleeve, an entry in a car house or similar, the flange 6 can be screwed to a complementary piece 20, as shown in Figure 2. The fixing piece 20 can be a body panel, a body floor, a housing wall, an interior wall or similar of a motor vehicle. The cable 8 can be guided through the complementary piece 20 and connected, for example, to a rigid or flexible flat conductor 21. The internal structure of housing part 2 is shown in Figure 3 in a longitudinal section. It can be seen that housing part 2 extends along the longitudinal axis 4 in the longitudinal direction. In the bottom region 2c of housing part 2, a cable sleeve 22 is provided, through which cable 8 is routed into the interior of housing part 2, preferably in a sealed manner. Cable 8 is arranged in the cable sleeve 22 so that it can be moved along the longitudinal axis 4. A seal 24 may be provided on the underside of the flange 6. This seal 24 is in contact with the fastening piece 20 in the connected state and thereby creates a seal on the flange 6. The housing part 2 is sleeve-shaped internally. Inside the housing part 2, which may be shaped like a hollow cylinder, for example, a spring 26 can be supported against the base 2c. The spring 26 extends within the housing part 2 along the longitudinal axis 4. Starting from the base 2c, the connecting part 12 is arranged on the housing part 2 following the spring 26. The connecting part 12 has a protrusion 12a that points radially outward and thus has two areas with different diameters. The area with the smaller diameter is shaped such that the spring 26 is movably positioned in an annular space between the connecting part 12 and the inner lateral surface of the housing part 2. The spring 26 is struck by the protrusion 12a, where the region with the smaller diameter merges with the region with the larger diameter. The connecting part 12 further extends towards the end face 2b. In the region of the end face 2b, the end face of the connecting part 12 rests against the collar 16. To assemble housing part 2, first insert spring 26 into the opening on the end face. Then, connective part 12 is placed with its protrusion 12a over spring 26, which is preferably pre-tensioned. When pushed along MA / a / ZUZJ / UUl / »0 of the longitudinal shaft 4, the connecting part 12 penetrates completely inside the housing part 2. The collar 16 is then locked inside the housing part 2 by means of a locking tab 16a. The collar 16 fixes the connecting part 12 inside the housing part 2. However, the connecting part 12 can be pressed longitudinally against the spring force of spring 26 towards the bottom 2c of the housing part 2. The connection portion 12 has a receptacle 28 on its side opposite cable 8. The receptacle 28 has a bottom 28a and an end opening 28b. The receptacle 28 extends into the base 28a in a conical shape. A spacer 30 can be arranged in the housing 28 at the base 28a, particularly in the region of the protrusion 12a. The receptacle 28 and the spacer 30 extend parallel to each other along the longitudinal axis 4. Corresponding to receptacle 28, the on-board power system connector has a pluggable element 32, as shown in Figure 4. Figure 4 shows housing portion 2 according to Figure 1. Opposite receptacle 28, the pluggable element 32 may be arranged on a flat cable 34. The flat cable 34 may have its insulation stripped 34a at the end (not shown) or along its length, exposing the bare conductor 34b. The pluggable element 32 may be attached to this bare conductor 34b, in particular by friction welding, for example. The flat cable 34 extends along a longitudinal axis 36. The longitudinal axis 36 is particularly parallel to the surface normal to the surface on which the pluggable element 32 is attached to the flat cable 34. An insulator 38 may be provided on the connectable element 32 on an end surface that faces the housing portion 2 in the installed state. The insulator 38 may be supported as a cap-like element on the end face of the connectable element 32 and have a pass-through opening. The connectable element 32, together with the insulator 38, is received by a second housing part 40, as shown in Figure 5. The second housing part 40 may include a cover 40a and a coupling portion 40b. The connection region 40b is formed to receive the first housing part 2 and has an opening that extends parallel to the longitudinal axis 36. The connectable element 32 extends within this opening, preferably concentrically with the opening. In the opening region, the connectable element 40b has an inner lateral surface 40c that coincides with the outer lateral surface 2a of MA / a / ZUZJ / UUl / »0 the first casing part 2. Starting from a flange 32a according to Figure 4, the connectable element 32 has a tapered shape in the direction of the insulator 36. In particular, the outer lateral surface of the connectable element 32 is congruent with the inner lateral surface of the receptacle 28. The flat cable 34 is housed in a sealed manner in the bare conductor region 34b by the cover 40a of the housing part 40. For this purpose, the cover 40a can be hinged to the connection region 40b, in particular with a film hinge, and can be connected to it in an interlocking manner. A locking lever 42 can be provided on the housing part 40. In this case, the locking lever is hinged on the outer side surface of the connection region 40. The locking lever 42 is pivotally mounted on the housing part 40 about an axis perpendicular to the longitudinal axis 36. The locking lever 32 interacts with a receptacle 44 in the first housing part 2, so that the housing parts 2, 40 can be locked together in the direction of the longitudinal axis 36 / 4. Figure 6 shows the two housing parts 2.40 in a longitudinal section. It can be seen that the connection region 40a receives the connectable element 32 in a sealed manner over the bare conductor 34b. A hole 46 can be provided within the connectable element 32. The insulator 38 covers the face of the coupling element 32 and extends into the hole 46. The hole 46 corresponds to the spacer 18. The spacer 18 extends along the longitudinal axis 4, and the hole 36 extends along the longitudinal axis 36. To join the two housing parts 2 and 40, housing part 2 is inserted into the opening of housing part 40. In this case, the spacer 38 engages with the hole 46. The inner side surface of the receptacle 28 contacts the outer side surface of the connectable element 32. The connecting part 12 is pushed onto the connectable element 32 until the spacer 18 rests against the bottom of the hole 46. In the assembled state, the locking lever 42, as shown in Figure 7, folds down and engages with the receptacles 44. This fixes the two housing parts 2, 40 with respect to the longitudinal axis 4, 36, which are collinear in the assembled state. As can be seen in Figure 8, in the assembled state, the connecting part 12 slides over the connectable element 32. The outer lateral surface of the element MA / a / ZUZJ / UUl / »0 The connectable element 32 is in direct contact with the inner side surface of the receptacle 28 of the connecting part 12. As a result of being pushed together, the spring 26 is compressed compared to its disassembled state. The spring 26 exerts a force in the direction of the connectable element 32 on the connecting part 12. This results in intimate, dynamically stable, and permanent contact between the connecting part 12 and the connectable element 32, so that a good electrical transition is possible. When pushed together, the connecting part 12 moves in the direction of the base 2c. In the process, the cable 8 also moves through the cable sleeve 22. Figure 9 shows another alternative for a first housing part 2. In this case, the cable 8 is attached to the connecting part 12 outside the housing part 2, and the connecting part 12 is movably arranged in the cable sleeve 22. This is shown again in Figure 10. The cable 8 is electrically and mechanically connected to the connecting part 12 outside the housing part 2. The connecting part 12 can be moved parallel to the longitudinal axis 4 inside the housing part 2, and this movement can tension the spring 26. Figure 11 shows the first housing part 2, as shown in Figure 9, in its installed state, i.e., with spring 26 compressed. It can be seen that, compared to Figure 10, the connecting part 12 has been pushed out of housing part 2 in sections. Spring 26 is compressed. Figure 12 shows the connector according to Figures 9-11 in a longitudinal section in the assembled state. In this case, it can be seen that, in this state, the connectable element 32 is housed within the receptacle of the connecting part 12. The spring 26 presses the connecting part 12 in the direction of the connectable element 32. The housing parts 2, 40 are fixed together by means of the locking lever 42. Figure 13 shows the connector according to Figure 12 in one view. The locking lever 42 is secured to the receptacles 44, such that the two housing parts 2, 40 are locked together. The connecting part 12 is pressed out of the housing part 2, at least in sections.
