Description

Technical Field

[0001] This invention relates to a vehicle electrical grid connector, particularly for use in vehicle electrical grids, especially in passenger cars, trucks, or other motor-driven motor vehicles. The vehicle electrical grid connector is particularly suitable for high-voltage vehicle electrical grids. Background Technology

[0002] In automotive applications, various types of high-voltage vehicle electrical systems exist. On one hand, this can be an electrical system with voltages higher than 12V, such as 24V or 48V. The increasing number of comfort appliances in motor vehicles has led to the perception that a 48V electrical system is advantageous. However, this requires different connectors compared to a conventional 12V electrical system. On the other hand, especially in electric motor-driven vehicles, the electrical system used for the drivetrain can also be understood as a high-voltage system. Drivetrains typically operate at several hundred volts, for example, around 400V. In addition to the high voltage, high current intensity is expected in these electrical systems because driving the vehicle requires significantly more power than operating comfort appliances. This also places particularly high demands on connectors in such systems.

[0003] In high-dynamic automotive applications, stringent requirements are placed on the mechanical stability of automotive electrical system connectors. These connectors must reliably and fault-freely ensure a stable connection. Due to the sometimes high current intensity, high contact resistance is also required for these connectors to minimize heat loss at the transition points. This necessitates a large contact area between the mating components. Summary of the Invention

[0004] To ensure a durable, stable, and fault-free connection with low contact resistance and high tolerance to dynamic loads, an on-board electrical grid plug connector is proposed.

[0005] The vehicle electrical grid connector has a first housing. A first connector is arranged in the first housing. The housing has a longitudinal extension along a longitudinal axis. Here, the housing is formed in particular by side walls, a bottom, and an open cover. When referring to the side walls here and below, both the plural and singular are always used. The cover may also be referred to as the end side. The housing is formed in particular integrally by the walls, the bottom, and the end sides. The housing has an opening on the end side according to the invention. The connector arranged within the housing is positioned in a manner that allows it to move along the longitudinal axis. The connector can translate along the longitudinal axis within the housing.

[0006] The plug connector also has a second housing component in addition to the first housing component. A second connector is arranged inside this second housing component. The second housing component, like the first housing component, is formed of side walls, an open cover, and a bottom. The cover may also be referred to as the end side. The housing is particularly integrally formed of the walls, bottom, and end side. According to the invention, the housing component has an opening on the end side. The connector arranged within this housing component is preferably fixed within the housing component relative to the longitudinal axis.

[0007] For connection, one housing component is inserted into another housing component, and the connectors are in electrical contact with each other thereon. For this purpose, the connectors are made of conductive material and / or coated. The connectors can be made of copper or aluminum, in particular. Coating the connectors, especially on the surfaces where they contact each other in the connected state, is also considered. Here, a metallic coating, especially tin plating, is possible.

[0008] In the connected state of the plug connector, the housing members are inserted into each other, such that the longitudinal axes of the housing members preferably extend collinearly. Furthermore, the second housing member is fixed relative to the first housing member at least longitudinally, and the second connector is in mechanical contact with the first connector. The contact surfaces of these connectors abut against each other. Specifically, one contact surface is the outer peripheral surface of one connector, which directly contacts the inner peripheral surface of the other connector.

[0009] For a secure electrical connection to be established, the contact surfaces must be firmly interlocked. Furthermore, for dynamic stability, the connection must remain stable even in dynamic environments. Therefore, according to the invention, a first connecting member is elastically supported along the longitudinal axis within a first housing member by a spring element. When the second housing member is connected to the first housing member, the first and second connecting members come into contact with each other. By inserting the housing members together, a clamping force arises in the second housing member against the spring force of the spring element, acting along the longitudinal axis towards the first housing member. Thus, the spring element is compressed in the connected state, thereby providing a sustained spring force to the connection between the two connecting members. The first connecting member moves longitudinally within the first housing member against the spring force.

[0010] According to one embodiment, one of the connectors is a sleeve-shaped receiving portion, and the other is a rod-shaped plug-in element that corresponds to the receiving portion. The receiving portion and the plug-in element are preferably centrally arranged in their respective housing members and extend longitudinally. The receiving portion and the plug-in element are preferably located on the central axis of their respective housing members.

[0011] A sleeve-shaped receiving portion is used to accommodate a plug-in element. The inner circumferential surface of the sleeve-shaped receiving portion is in direct contact with the outer circumferential surface of the plug-in element in the connected state. A housing member having a connector with a sleeve-shaped receiving portion is preferably inserted into a housing member having a connector with a rod-shaped plug-in element. An annular space is formed between the inner circumferential surface of the housing member and the rod-shaped plug-in element. Another housing member, along with its sleeve-shaped receiving portion, is inserted into this annular space. The housing member having the sleeve-shaped receiving portion is inserted into the end opening of the housing member having the plug-in element. Here, the plug-in element is inserted into the end opening of the housing member having the sleeve-shaped receiving portion. Therefore, the outer circumferential surface of the plug-in element contacts the inner circumferential surface of the sleeve-shaped receiving portion.

[0012] This invention proposes that, in the connected state, the plug-in element is inserted into the receiving portion, and the spring element is compressed. The spring element is particularly a steel spring, preferably a compression spring. However, the spring element can also be made of plastic. The spring element can be elastically compressed along the longitudinal axis, wherein, in the tensioned state, the spring element applies force to the connecting member, causing the connecting member to be pressed against the other connecting member. Because the housing members are longitudinally fixed to each other in the connected state, the spring force acts on the contact surface between the two connecting members.

[0013] According to one embodiment, in the connected state, one of the housing components is at least partially inserted into an opening at the end of the other housing component. This insertion brings the sleeve-shaped receiving portion and the insertion element into direct contact with each other.

[0014] The sleeve-shaped receiving portion preferably extends longitudinally along its longitudinal axis inside the housing member. The sleeve-shaped receiving portion has tubular sidewalls and a bottom on one end and an opening on the other end. The end-side opening of the sleeve-shaped receiving portion is oriented in the same direction as the end-side opening of the housing member. The bottom is preferably closed. The housing member has a shape that surrounds the sleeve-shaped receiving portion, and is also preferably sleeve-shaped with tubular sidewalls.

[0015] The rod-shaped plug element extends longitudinally. Within a housing member in which the rod-shaped plug element is mounted, the plug element extends longitudinally along the longitudinal axis of the housing member. The plug element preferably has a tubular outer circumferential surface that coincides with the tubular inner circumferential surface of the sleeve-shaped receiving portion. The tubular plug element is surrounded by the housing member, wherein the sidewalls of the housing member, particularly the inner circumferential surfaces of the sidewalls of the housing member, extend parallel to the outer circumferential surface of the plug element. Specifically, the outer circumferential surface of the housing member with the plug element coincides with the inner circumferential surface of the housing member with the sleeve-shaped receiving portion. Therefore, the housing member with the sleeve-shaped receiving portion can be inserted into the housing member with the plug element, and the housing member abuts against each other with its inner and outer circumferential surfaces.

[0016] In the connected state, the first housing component is inserted into the end opening of the second housing component, or the second housing component is inserted into the end opening of the first housing component.

[0017] According to one embodiment, the receiving portion tapers gradually from the opening at the end towards the bottom, particularly tapering in a conical manner. This gradual taper of the receiving portion results in a better form fit between the plug element and the receiving portion. In particular, the plug element can be inserted into the receiving portion until the contact surfaces, i.e., the outer peripheral surface of the plug element and the inner peripheral surface of the receiving portion, are in contact with each other under all circumstances. The gradual taper, especially the conical taper, is used for tolerance compensation because it ensures direct mechanical contact between the plug element and the receiving portion at all times in the inserted state.

[0018] It is also proposed that the plug element tapers gradually towards its end face, especially tapering in a conical manner. The plug element and the receiving portion are preferably shaped uniformly and, in particular, have tapering portions that extend uniformly, so that the plug element, when inserted into the receiving portion, rests its outer circumferential surface against the inner circumferential surface of the receiving portion. A spring element causes a clamping force on the plug element against the receiving portion, or vice versa. The spring force acting along the longitudinal axis presses the plug element and the receiving portion against each other, so that their contact surfaces are firmly connected.

[0019] According to one embodiment, in the connected state, the inner circumferential surface of the receiving portion and the outer circumferential surface of the plug-in element are in direct contact with each other. This direct contact ensures good conductivity at the transition point. In particular, ohmic losses are reduced by the large contact area ensured by the consistent circumferential surface.

[0020] According to one embodiment, a spacer extends from the bottom of the receiving portion toward an end opening in the receiving portion. The openings of the housing member extending along the longitudinal axis and the openings of the sleeve-shaped receiving portion extending along the longitudinal axis are particularly collinear. The spacer can be arranged on a central axis. The spacer also extends along the longitudinal axis from the bottom toward the end opening of the receiving portion. The spacer can be rod-shaped. In the sleeve-shaped receiving portion, an annular space is formed between the spacer and the inner circumferential surface of the sleeve-shaped receiving portion. The spacer serves to ensure that the insertion element can only be inserted into the receiving portion to a certain extent. This prevents excessively strong locking between the receiving portion and the insertion element.

[0021] In order for the plug-in element to be inserted into the receiving portion, the plug-in element must accommodate the spacer. For this purpose, the plug-in element has a recess extending along its longitudinal axis from its end side. The housing component with the plug-in element also has a receiving portion in which the plug-in element is disposed. This receiving portion extends along its longitudinal axis. The plug-in element also extends along its longitudinal axis. Preferably, the longitudinal axis of the housing component's receiving portion and the longitudinal axis of the plug-in element are collinear. Inside the plug-in element, a recess in the form of, for example, a hole can be provided on the central axis of the plug-in element.

[0022] The spacer is embedded in the recess in the installed state. That is, when the plug-in element is inserted into the sleeve-shaped receiving portion, the spacer is simultaneously pushed into the recess. The recess has a certain depth inside the plug-in element. Inside the recess, for example, a stop for the spacer is formed at the bottom. This ensures that the plug-in element is inserted into the sleeve-shaped receiving portion only to a certain depth, that is, until the spacer rests against the stop of the recess.

[0023] According to one embodiment, a first connector is connected to a flexible cable. The first connector is elastically hinged to a spring element and is translatably movable within a housing along a longitudinal axis. To prevent this mobility from being excessively affected by the cable connected to the connector, it is suggested that the flexible cable be introduced into the interior of the first housing through a threaded portion and movably supported in the threaded portion along the longitudinal axis, or that the first connector be led out from the interior of the housing through a threaded portion and movably supported in the threaded portion along the longitudinal axis. The threaded portion particularly has a longitudinal extension along a longitudinal axis that is parallel to, preferably collinear with, the longitudinal axis of the housing or receiving portion. Preferably, the threaded portion extends parallel to the longitudinal axis such that the movement of the connector against the spring element along the longitudinal axis is not hindered by the movement of the cable or connector in the threaded portion. The direction of movement of the cable or connector in the threaded portion is preferably parallel to the direction of movement of the connector against the spring element within the housing.

[0024] According to one embodiment, a first connector is supported within the housing member on a radially inwardly pointing flange on an end-side opening of the housing member. This flange preferably preloads a spring element. The spring element is hinged to the connector such that it applies a spring force to the connector in the direction of the end-side opening of the housing member. The connector is secured or supported within the housing member by the flange. The spring element can be initially inserted into the housing member through the end-side opening. The connector is then pressed against the spring element and inserted into the housing member through the end-side opening.

[0025] To secure the connector inside the housing element, a flange can be mounted onto the end opening of the housing element and locked in place. For this purpose, the flange can have a surrounding circumferential surface that abuts against the inner circumferential surface of the housing element's receiving portion and is locked there in the installed state. A recessed and raised locking mechanism can be provided between the circumferential surface of the flange and the inner circumferential surface of the housing element. The surrounding circumferential surface of the flange can be arranged in an annular space between the outer circumferential surface of the first connector and the inner circumferential surface of the first housing element. The connector is secured by the flange during its translational movement along the longitudinal axis toward the end opening, thus preventing loss of the connector within the first housing element. In the direction toward the bottom of the housing element, a spring element acts on the connector, and a force overcoming the spring force must be used to press the connector away from the flange toward the bottom of the first housing element.

[0026] According to one embodiment, a spring element is supported between the bottom of a first housing member and a radially outwardly pointing shoulder that at least partially surrounds a first connector. The first connector may have two regions with different outer diameters. In the installed state, the first region is located in the direction of the end opening of the first housing member and has an outer diameter that substantially corresponds to the inner diameter of the housing member. The second region of the connector may have a smaller diameter and is therefore formed in the form of a step or a recess. The spring element can be arranged in the space formed between the connector and the first housing member and hinged to the step. In the connected state of the plug connector, the spring element is compressed and pressed against the shoulder with a spring force parallel to the longitudinal axis, thereby pressing the first connector toward the direction of the end opening of the first housing member.

[0027] According to one embodiment, a surrounding seal is arranged on the outer peripheral surface of one of the housing components. This seal contacts the inner peripheral surface of the other housing component in the connected state. Alternatively, a surrounding seal is arranged on the inner peripheral surface of one of the housing components, contacting the outer peripheral surface of the other housing component in the connected state. Or, a surrounding seal is arranged between the inner peripheral surface of one housing component and the outer peripheral surface of the other housing component. In the connected state, any gaps that may form between the outer peripheral surface of the first housing component and the inner peripheral surface of the other housing component can be sealed by this seal, thereby protecting the connection between the sleeve-shaped receiving portion and the plug-in element from environmental influences.

[0028] According to one embodiment, a second connector is materially fixed to an electrical conductor, particularly a solid material conductor. The electrical conductor, especially a flat conductor, may be deinsulated at its end or along its path. Within the deinsulated area, a plug-in element, particularly welded or threaded, can be arranged on a wide surface of the flat conductor in the form of a bolt. This bolt can then serve as a plug-in element.

[0029] The present invention proposes that a second housing member has a conductor receiving portion for accommodating a conductor, specifically a through portion that accommodates the conductor along its laying direction. The second housing member is capable of accommodating the conductor. For this purpose, the conductor receiving portion may have a cover, which is hinged, particularly in the form of a thin-film hinge, to the remainder of the housing member. The conductor is embedded in the conductor receiving portion, particularly in its uninsulated region. The insulation portion of the conductor is also located in the region of the conductor receiving portion. The cover of the conductor receiving portion can then be placed on the conductor on the side opposite to the remainder of the second housing member and thus cover-shaped to close the conductor receiving portion. A seal may be provided around the conductor receiving portion in the region for the conductor's inlet, so that no moisture can enter the conductor receiving portion in the longitudinal direction of the conductor. The cover of the conductor receiving portion can be securely fixed to the remainder of the second housing member, particularly by clips or locks.

[0030] The housing component extends preferably along the surface normal of the conductor's wide surface, originating from the conductor receiving portion. The conductor receiving portion extends particularly perpendicular to the longitudinal axis of the second housing component. The longitudinal axis of the second housing component and the conductor receiving portion, or the conductor inserted into the conductor receiving portion, extend at an angle, preferably perpendicular to each other.

[0031] According to one embodiment, an insulator is provided on the second connector, covering the end side. The second connector is preferably a plug-in element. This plug-in element is disposed within a second housing member. For contact protection, it may be meaningful to insulate the plug-in element at its end side inside the housing, thereby preventing unintentional contact at its end side.

[0032] According to one embodiment, the insulator is suggested to have an opening for receiving a spacer, specifically coaxial with a recess of a mating element. Thus, the insulator provides contact protection while allowing the mating element and the spacer-equipped receiving portion to be mated together.

[0033] According to one embodiment, a fixing rod is arranged on one of the housing components, pivotable about an axis perpendicular to the longitudinal axis. This fixing rod, in the connected state, engages with a fixing mechanism on the other housing component. This ensures that the connecting components are longitudinally fixed to each other. The housing components are inserted into each other and fixed to each other, at least along the longitudinal axis, by means of the fixing rod and the fixing mechanism. Attached Figure Description

[0048] Figure 1 A first housing 2 of an on-board electrical grid connector is shown. The housing 2 extends longitudinally along a longitudinal axis 4. The first housing 2 has an outer peripheral surface 2a and is defined by an end side 2b. On the side opposite to the end side 2b, particularly on the bottom 2c of the first housing, a flange 6 can project radially from the outer peripheral surface 2a. In the region of the bottom 2c, the housing 2 has a through opening through which a flexible cable 8 is guided.

[0049] Between the end side 2b and the bottom 2c, a surrounding seal 10 may be provided on the outer peripheral surface 2a.

[0050] A connector 12 is provided inside the housing 2. The connector 12 extends toward the opening 14 on the end side 2b. The connector 12 abuts against the flange 16. The connector 12 can move parallel to the longitudinal axis 14 inside the housing 2. A spacer 18, which can be metallic or non-metallic, can be provided inside the connector 12.

[0051] To install the vehicle electrical grid connector in areas such as cable routing areas, undercarriage routing areas, access areas to the housing, or similar components, it can be done as follows: Figure 2 As shown, flange 6 is secured to mounting member 20 with screws. Mounting member 20 may be a body panel, body floor panel, housing wall, inner wall, or similar component of a motor vehicle. Cable 8 may be guided through mounting member 20 and connected, for example, to rigid or flexible flat conductor 21.

[0052] The internal structure of housing component 2 is Figure 3The diagram is shown in a longitudinal section. It can be seen that the housing 2 extends longitudinally along the longitudinal axis 4. A cable guide 22 is provided in the area of ​​the bottom 2c of the housing 2, through which the cable 8 is preferably guided in a sealed manner into the interior of the housing 2. The cable 8 is arranged in the cable guide 22 in a manner that allows it to move along the longitudinal axis 4. A seal 24 can be provided on the bottom side of the flange 6, wherein the seal 24 contacts the mounting member 2O in the connected state, thereby creating a seal at the flange 6.

[0053] The housing 2 is sleeve-shaped internally. Inside the housing 2, which can be configured as, for example, a hollow cylinder, the spring 26 rests against the bottom 2c. The spring 26 extends along the longitudinal axis 4 within the housing 2. Starting from the bottom 2c, immediately following the spring 26, a connector 12 is arranged within the housing 2. The connector 12 has a radially outward-pointing shoulder 12a and therefore has two regions of different diameters. The region with the smaller diameter is shaped such that the spring 26 can be movably arranged in the annular space between the connector 12 and the inner circumferential surface of the housing 2. The spring 26 is stopped by the shoulder 12a, at which the region with the smaller diameter transitions to the region with the larger diameter.

[0054] Furthermore, the connector 12 extends toward the end side 2b. In the region of the end side 2b, the end face of the connector 12 stops on the flange 16.

[0055] To assemble housing 2, spring 26 is first inserted into the opening at one end. Then, connector 12 is positioned onto spring 26 with its shoulder 12a, and spring 26 is preferably pre-tensioned. By pushing along the longitudinal axis 4, connector 12 is fully inserted into the cavity of housing 2. Next, flange 16 is locked inside housing 2 using locking protrusion 16a. Connector 12 is secured inside housing 2 by flange 16. However, connector 12 can be pressed against the bottom 2c of housing 2 in the longitudinal direction against the spring force of spring 26.

[0056] The connector 12 has a receiving portion 28 on its side opposite to the cable 8. The receiving portion 28 has a bottom 28a and an opening 28b on the end side. The receiving portion 28 extends in a conical shape toward the bottom 28a. On the bottom 28a, especially in the area of ​​the shoulder 12a, a spacer 30 may be arranged in the receiving portion 28. The receiving portion 28 and the spacer 30 extend parallel to each other along the longitudinal axis 4.

[0057] Corresponding to the receiving portion 28, the vehicle electrical network plug connector has a plug element 32, such as Figure 4 As shown. Figure 4 Showing according to Figure 1The housing 2. Opposite to the receiving portion 28, a plug element 32 can be arranged on the flat cable 34. The flat cable 34 may have its insulation 34a removed at its end (not shown) or along its path, exposing the bare conductor 34b. The plug element 32 can be fixed to the exposed conductor 34b, particularly by material fit, for example by friction welding. The flat member 34 extends along a longitudinal axis 36. The longitudinal axis 36 is particularly parallel to the surface normal on the surface on which the plug element 32 is fixed to the flat cable 34.

[0058] The plug element 32 may have an insulator 38 on its end face facing the housing 2 in the installed state. The insulator 38 may be placed as a cap-shaped element on the end face of the plug element 32 and has a through opening.

[0059] The plug-in element 32, together with the insulator 38, is housed in the second housing 40, such as Figure 5 As shown. The second housing member 40 may have a cover 40a and a insertion region 40b. The insertion region 40b is configured to receive the first housing member 2 and has an opening extending parallel to the longitudinal axis 36. The insertion element 32 extends within this opening, preferably concentrically with the opening. The insertion element 40b has an inner circumferential surface 40c in the region of the opening, which coincides with the outer circumferential surface 2a of the first housing member 2.

[0060] according to Figure 4 The plug element 32 is formed by gradually tapering from the flange 32a toward the insulator 36. In particular, the outer peripheral surface of the plug element 32 is consistent with the inner peripheral surface of the receiving portion 28.

[0061] The flat cable 34 is sealed in the area of ​​the exposed conductor 34b by a cover 40a of the housing 40. For this purpose, the cover 40a may be hinged, in particular by means of a thin-film hinge, to the insertion area 40b and snap-fitted to the insertion area.

[0062] A fixing rod 42 may be provided on the housing member 40. The fixing rod is hinged to the outer peripheral surface of the insertion area 40. The fixing rod 42 is pivotally supported on the housing member 40 with respect to an axis perpendicular to the longitudinal axis 36. The fixing rod 42 interacts with the receiving portion 44 on the first housing member 2, so that the housing members 2 and 40 can be fixed relative to each other in the direction of the longitudinal axis 36 / 4.

[0063] Figure 6The two housing members 2 and 40 are shown in longitudinal section. It can be seen that the mating region 40a sealably accommodates the mating element 32 at the exposed conductor 34b. A hole 46 can be provided inside the mating element 32. An insulator 38 covers the mating element 32 at its end and extends into the hole 46. The hole 46 corresponds to a spacer 18. The spacer 18 extends along the longitudinal axis 4, and the hole 36 extends along the longitudinal axis 36. To engage the two housing members 2 and 40, housing member 2 is pushed into the opening of housing member 40. Here, spacer 38 engages with hole 46. The inner peripheral surface of the receiving portion 28 contacts the outer peripheral surface of the mating element 32. Connector 12 is pushed onto mating element 32 until spacer 18 abuts against the bottom of hole 46.

[0064] In the assembled state, such as Figure 7 As shown, the fixing rod 42 is flipped and engaged with the receiving part 44. Thus, the two housing parts 2, 40 are fixed relative to the longitudinal axes 4, 36 that extend collinearly in the assembled state.

[0065] As in Figure 8 As can be seen, in the assembled state, connector 12 is pushed onto plug element 32. The outer peripheral surface of plug element 32 is in direct contact with the inner peripheral surface of the receiving portion 28 of connector 12. By pushing them together, spring 26 is compressed relative to the unassembled state. Spring 26 applies force to connector 12 in the direction of plug element 32. This creates a tight, dynamically stable, and durable contact between connector 12 and plug element 32, thereby enabling good electrical transition. When pushed together, connector 12 moves towards the bottom 2c. Here, cable 8 also moves through cable threading portion 22.

[0066] Figure 9 An alternative to the first housing member 2 is shown. Here, the cable 8 is fixed to the connector 12 outside the housing member 2, and the connector 12 is movably arranged in the cable threading portion 22. This is in Figure 10 As shown again, cable 8 is electrically and mechanically connected to connector 12 outside housing 2. Connector 12 can move parallel to longitudinal axis 4 inside housing 2, thereby tensioning spring 26.

[0067] Figure 11 It shows that according to Figure 9 The first housing component 2 is installed in the following state: when the spring 26 is compressed. It can be seen that, relative to... Figure 10 The connector 12 is partially extended from the housing 2. The spring 26 is tensioned.

[0068] Figure 12 It shows that according to Figures 9-11This is a longitudinal sectional view of the plug connector in its assembled state. It can be seen that, in this state, the plug element 32 is housed within the receiving portion of the connector 12. The spring 26 presses the connector 12 toward the plug element 32. The housing parts 2 and 40 are fixed relative to each other by the retaining rod 42.
