Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more particularly to a wire harness adaptive integration structure, a base supporting extended integration, and an integrated connector. Background Technology

[0002] The arrangement of signal harnesses and wires on the battery packs of new energy vehicles is generally quite messy. Currently, some manufacturers integrate multiple interfaces through encapsulated junction boxes for the connection of signal harnesses and wires to the terminals, and then install them on or near the battery pack, which can reduce the messiness of the various harnesses and wires to a certain extent.

[0003] But current junction boxes (such as Figure 7 It is still just a simple integration of various interfaces, with each interface distributed on different surfaces of the junction box. This makes the overall size of the junction box relatively large and the integration level not high enough.

[0004] Therefore, this application proposes a wire harness adaptive integration structure, a base supporting extended integration, and an integrated connector. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adaptive integrated wiring harness structure, a base supporting extended integration, and an integrated connector. This structure integrates various wiring harnesses from the battery pack onto the electrical connector in a simple, compact, and low-cost manner. This not only makes the wiring near the battery pack of new energy vehicles neater but also prevents problems such as wiring harness breakage, deformation, tangling, and wire detachment caused by vibrations during driving. It also avoids affecting the electrical performance or signal transmission of the wiring harness, thus preventing impacts on the real-time control of the vehicle and improving driving safety. This is of great significance for autonomous driving and assisted driving.

[0006] Firstly, in order to achieve the above objectives, the present invention provides the following technical solution: The wire harness adaptive integrated structure includes a multi-core signal connector plug housing for fixing the wire harness and a base plate for attaching to a base in an electrical connector, the multi-core signal connector plug housing being connected to the base plate via a floating assembly; The floating assembly includes a housing for connecting the substrate, a connecting rod for connecting the housing of the multi-core signal connector plug, a ball head at the end of the connecting rod, and a pressure plate elastically connected inside the housing. The radial section of the housing near the multi-core signal connector plug housing is arc-shaped or V-shaped. The surface of the housing near the multi-core signal connector plug housing is provided with a linear hole aligned with the length direction of the multi-core signal connector plug housing. The width of the linear hole is greater than the diameter of the connecting rod and smaller than the diameter of the ball head. When the connecting rod is subjected to the force of the multi-core signal connector plug housing, the pressure plate receives a reaction force and provides thrust to the ball head.

[0007] The above structure integrates various wiring harnesses at the battery pack onto the electrical connector. It is simple in structure, small in size, and low in cost. It not only makes the wiring near the battery pack of new energy vehicles neater, but also prevents problems such as wire harness breakage, deformation, tangling, and wire detachment caused by vibration during driving. It avoids the electrical performance or signal transmission of the wiring harness from being affected, which would affect the real-time control of the vehicle and improve driving safety performance. It is of great significance for autonomous driving and assisted driving.

[0008] In one embodiment, the length of the linear hole is 3 to 20 mm.

[0009] In one embodiment, the lateral swing angle of the connecting rod in the linear hole does not exceed 30°.

[0010] In one embodiment, the deformation stroke of the elastic element is 3 to 10 mm.

[0011] The above structure can accommodate the vibration resistance requirements of wiring and the anti-detachment requirements of wire harness connections when used in new energy vehicles, and will not affect other components such as the terminals of the electrical connector itself, so that the integration of the wire harness on the electrical connector does not affect the operation of the electrical connector itself.

[0012] In one embodiment, the pressure plate is connected to the substrate by an elastic element, the elastic element including at least one of a spring and a sheet spring, the housing includes a frame at one end near the substrate and a limiting frame at the other end, the frame is detachably connected to the substrate, and the initial state of the elastic element after the floating component is assembled is a compressed state.

[0013] In one embodiment, the axial section of the frame is rectangular or waist-shaped, and the radial section of the frame is rectangular.

[0014] The above structure allows the connecting rod to automatically return to the position closest to the outer shell, thereby maintaining the maximum distance between the outer shell surface and the multi-core signal connector plug outer shell surface, providing the maximum floating range for disordered tensile forces during vibration, especially the lateral and vertical swing angles.

[0015] In one embodiment, the pressure plate slides against the inner wall of the frame.

[0016] The above structure keeps the sliding direction of the pressure plate stable, ensuring that the pressure of the pressure plate on the ball head is always forward.

[0017] In one embodiment, the elastic element is a spring sheet, and the side wall of the housing is provided with an opening to provide deformation stroke for the spring sheet. The end of the spring sheet located outside the housing is fixedly connected to the substrate.

[0018] With the above structure, the size of the spring can be made slightly larger than that of the spring, so as to avoid insufficient elasticity due to insufficient elastic deformation stroke, which would prevent the spring from providing enough reaction force to the pressure plate. This makes it easier to provide more forward and backward floating stroke for the multi-core signal connector plug housing.

[0019] In one embodiment, the length direction of the substrate is aligned with the length direction of the multi-core signal connector plug housing, and the end of the substrate away from the floating component is provided with a base plate for connecting the base, and the base plate is provided with a wire hole for the wire harness to pass through.

[0020] In one embodiment, the base plate is provided with a quick-connect structure, which includes at least one of screws and clips.

[0021] The above structure meets the needs of rapid disassembly and assembly during battery pack maintenance and battery replacement in new energy vehicles.

[0022] Secondly, in order to achieve the above objectives, the present invention also provides the following technical solution: A base that supports expansion and integration is used for mounting terminals in electrical connectors. The base has several wire-passing holes for wire harnesses to pass through. The wire-passing holes are located in positions not covered by the terminals. The base has mounting positions for mounting substrates near the wire-passing holes.

[0023] The above structure provides modular and expandable mounting positions for the integrated structure, making the wiring of various wire harnesses in the new energy vehicle battery pack more convenient. It is also suitable for use with battery packs of various models, functions and specifications. User manufacturers can customize the integration of wire harnesses, making it highly adaptable.

[0024] Thirdly, in order to achieve the above objectives, the present invention also provides the following technical solution: Integrated connector, including the above-described adaptive integrated wire harness structure and base.

[0025] Compared with the prior art, the beneficial effects of this invention are as follows: by integrating various wire harnesses at the battery pack onto the electrical connector in a simple, small-sized, and low-cost manner, it not only makes the wiring near the battery pack of new energy vehicles neater, but also prevents problems such as wire harness breakage, deformation, tangling, and wire detachment caused by vibration during driving. It avoids the impact on the electrical performance or signal transmission of the wire harness, which would affect the real-time control of the vehicle, thus improving driving safety performance. This is of great significance for autonomous driving and assisted driving. Attached Figure Description

[0029] Currently, in new energy vehicles, the wiring harnesses near the battery pack are arranged in a rather messy manner, and some manufacturers have introduced solutions such as... Figure 7 The integrated solution shown is simply a box that integrates the terminals of various wiring harnesses A. As can be seen, the size is still relatively large, which is not suitable for vehicles with high range requirements.

[0030] It should be understood that the following embodiments are based on the integration of various wire harnesses A into the electrical connector itself. These integrated wire harnesses A can be signal wire harnesses A or power lines. However, apart from the wiring harnesses A already present in the electrical connector, the additionally integrated wire harnesses A generally do not have a direct electrical connection with the electrical connector itself, or the additionally integrated wire harnesses A are unrelated to the electrical connector itself. Therefore, the following embodiments are all intended to solve the problem of complex wiring in new energy vehicles, without considering any electrical connection between these wire harnesses A and the electrical connector.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1 Please see Figure 1-6 The present invention provides the following technical solution: a wire harness adaptive integrated structure, including a multi-core signal connector plug housing 2 for fixing wire harness A and a substrate 3 for attaching to the base 1 in the electrical connector, wherein the multi-core signal connector plug housing 2 is connected to the substrate 3 by a floating component 4; The floating assembly 4 includes a housing 41 for connecting the substrate 3, a connecting rod 42 for connecting the multi-core signal connector plug housing 2, a ball head 43 at the end of the connecting rod 42, and a pressure plate 45 elastically connected inside the housing 41. The radial section of the housing 41 near the multi-core signal connector plug housing 2 is arc-shaped or V-shaped. The surface of the housing 41 near the multi-core signal connector plug housing 2 is provided with a linear hole 411 aligned with the length direction of the multi-core signal connector plug housing 2. The width of the linear hole 411 is greater than the diameter of the connecting rod 42 and smaller than the diameter of the ball head 43. When the connecting rod 42 is subjected to the force of the multi-core signal connector plug housing 2, the pressure plate 45 obtains a reaction force and provides a thrust to the ball head 43.

[0033] As an optional implementation of the present invention, during assembly, the multi-core signal connector plug housing 2 is used to fix the multi-core wire harness A to be integrated. Then, the connecting rod 42 is passed through the wire hole 411 from the housing 41 and fixed to the multi-core signal connector plug housing 2. Then, the pressure plate 45 is placed into the housing 41 and the housing 41 is installed on the surface of the substrate 3. At this time, the elastic member 46 abuts against the back of the pressure plate 45. Finally, the substrate 3 is installed on the base 1 of the electrical connector to complete the integration of the wire harness A.

[0034] The entire assembly process is relatively convenient to operate, and there are relatively few parts, only 6 to 7 types, with a minimum of 9 parts. There are also no parts with complex shapes, and they are all easy to mold and injection molded, so the production cost is relatively low.

[0035] It should be understood that the aforementioned electrical connectors are generally installed on or near the battery pack (in the scenario described in this embodiment, the wiring harness A is usually the most numerous and the wiring is the most messy at this location).

[0036] Integrating wire harness A into the electrical connector at or near the battery pack not only makes the wiring around the automotive battery pack neater, but also, as is foreseeable, lowers the installation requirements for the electrical connector compared to the existing method of simply integrating each terminal block onto the exterior of a box. It only requires multiple mounting positions for mounting the base plate 3 (which can be screw holes for tightening screws or slots for snap-fit ​​connections). This allows for modular integration of the connector, enabling the replacement of only the appropriate multi-core signal connector plug housing 2 for different wire harnesses A. The mounting position design on the base plate 3, housing 41, and even the electrical connector base 1 can be standardized. Therefore, this embodiment supports the modular integration of external wire harness A into the electrical connector. Considering the limited space for battery pack installation, the structures of components such as the aforementioned substrate 3 are relatively simple, allowing them to be manufactured in smaller sizes (in fact, such as...). Figure 1 and Figure 3 As shown, after assembly, the substrate 3 and the multi-core signal connector plug housing 2 occupy 40-50mm of height space and 10mm of additional width space (with no further increase in length). The height of the terminals and the MSD manual switch on the existing electrical connector are close to the height of the substrate 3 and the multi-core signal connector plug housing 2. The wire hole 11 on the electrical connector base 1 itself requires more than 10mm of width and 40mm of width space. Regardless of the calculation method, this is much lower than the space occupied by the current box integration form. Therefore, it is beneficial for application in the battery packs of new energy vehicles with high range performance requirements. Furthermore, these mounting positions are not related to the terminals of the electrical connector itself, so they will not affect the electrical or data transmission performance of harness A or the terminals themselves.

[0037] Furthermore, when new energy vehicles are in operation, these wiring harnesses A will vibrate in any direction, which manifests as traction on the wiring harness A along its length. The linear hole 411 provides a sliding path and vertical swing for the ball head 43 and the connecting rod 42. Since the diameter of the connecting rod 42 is smaller than the width of the linear hole, the ball head 43 can swing laterally. With the pressure plate 45 elastically connected within the housing 41, the ball head 43 can extend and retract in the front-to-back direction (and this extension and retraction is reset). Therefore, when the multi-core signal connector plug housing 2 receives vibration from any direction of the wire harness A, the multi-core signal connector plug housing 2 can swing up and down, swing left and right, slide up and down and float back and forth in the housing 41. It can then adapt to the vibration force and move within a certain range. The linear hole, housing 41, and pressure plate 45 all have a limiting effect on the various movements of ball head 43 and connecting rod 42. There will be no problem of entanglement due to the full radial rotation of the multi-core signal connector plug housing 2 itself, or the problem of the wire harness A terminal falling off due to large-amplitude movement along the tension direction.

[0038] Therefore, by adopting the above integrated structure, problems such as wire harness A breakage, deformation, tangling, and wire disconnection are less likely to occur, thus avoiding the impact on the electrical or signal transmission performance of wire harness A when new energy vehicles are in motion, preventing safety issues caused by the impact on the real-time control of the vehicle, which is of great significance for autonomous driving and assisted driving. In this embodiment, the multi-core signal connector plug housing 2 refers to an insulating component capable of covering the wire harness A. In most cases, the multi-core signal connector plug housing 2 should be a shell-like body with a specific shape, such as... Figure 2 As shown, all wire harnesses A are bundled within this shell and can be connected to the connecting rod 42. Although common nylon cable ties can also be used to connect the connecting rod 42 via thermoplastic bonding, this is obviously not convenient in operation. Of course, there are also custom-designed shell-shaped multi-core signal connector plug housings 2, such as the housing in the utility model patent application (integrated connector) with application number CN202521972264.3.

[0039] In some cases, the connection between the link 42 and the multi-core signal connector plug housing 2 can be integrally formed, and the connection between the link 42 and the ball head 43 can be detachable, for example by means of threads, or by means of equivalents, so that the multi-core signal connector plug housing 2 can be floated in the housing 41.

[0040] In this embodiment, to ensure that the swing of the ball head 43 in the housing 41 is not obstructed by the pressure plate 45, the side of the pressure plate 45 that contacts the ball head 43 should be flat to avoid affecting the upward and downward sliding of the ball head 43.

[0041] In this embodiment, to ensure that the ball head 43 slides stably in the housing 41, the force exerted by each elastic element 46 on the pressure plate 45 should be consistent, and the supporting force of the elastic element 46 on the pressure plate 45 should be balanced. Of course, those skilled in the art can design the pressure plate 45 to be connected in a sliding fit with the housing 41.

[0042] This implementation integrates various wiring harnesses A at the battery pack onto the electrical connector in a simple, small, and low-cost manner. This not only makes the wiring near the battery pack of new energy vehicles neater, but also prevents problems such as breakage, deformation, tangling, and wire detachment of wiring harness A due to vibration during driving. It avoids affecting the electrical performance or signal transmission of wiring harness A, which could affect the real-time control of the vehicle, thus improving driving safety performance. This is of great significance for autonomous driving and assisted driving.

[0043] Example 2 For wiring harness A in the battery pack of a new energy vehicle, harness A can directly pass through the base plate 31 of the electrical connector mounted on the surface of the battery pack, which simplifies the wiring. However, as described in Example 1, tension along the length of harness A can easily cause it to break or stretch, leading to serious consequences. These consequences range from affecting data transmission efficiency and causing delays in autonomous driving and assisted driving control, to directly causing electrical performance or data transmission failure. This is particularly relevant given the current issue of some data not being able to be uploaded after a collision in new energy vehicles.

[0044] Therefore, the floating range of the aforementioned integrated structure should be further limited.

[0045] Please see Figure 1 The present invention provides the following technical solution: an adaptive integrated structure for wire harness A, including a multi-core signal connector plug housing 2 for fixing wire harness A and a base plate 3 for attaching to the base 1 in the electrical connector, wherein the multi-core signal connector plug housing 2 is connected to the base plate 3 by a floating component 4. The floating assembly 4 includes a housing 41 for connecting the base plate 3, a connecting rod 42 for connecting the multi-core signal connector plug housing 2, a ball head 43 at the end of the connecting rod 42, and a pressure plate 45 elastically connected inside the housing 41. The radial section of the housing 41 near the multi-core signal connector plug housing 2 is arc-shaped or V-shaped. The surface of the housing 41 near the multi-core signal connector plug housing 2 is provided with a linear hole 411 aligned with the length direction of the multi-core signal connector plug housing 2. The width of the linear hole 411 is greater than the diameter of the connecting rod 42 and smaller than the diameter of the ball head 43. The length direction of the base plate 3 is aligned with the length direction of the multi-core signal connector plug housing 2. The end of the base plate 3 away from the floating assembly 4 is provided with a base plate 31 for connecting the base 1. The base plate 31 is provided with a wire hole 311 through which the wire harness A can pass. When the connecting rod 42 is subjected to the force of the multi-core signal connector plug housing 2, the pressure plate 45 obtains a reaction force and provides a thrust to the ball head 43; The length of the linear hole 411 is 3 to 20 mm, the lateral swing angle of the connecting rod 42 in the linear hole 411 does not exceed 30°, and the deformation stroke of the elastic element 46 is 3 to 10 mm. As an optional implementation of this invention, the floating range of wire harness A is limited to a suitable range to avoid insufficient vibration resistance due to an excessively large floating range. Preferably, the length of the linear hole is 10mm, the lateral swing angle of the connecting rod 42 is 20°, the length of the connecting rod 42 is 12mm, and the deformation stroke of the elastic element 46 is 5mm, achieving a maximum stretching distance of 15mm for wire harness A, which can meet standards such as SAE USCAR-2 (10±5mm). Although there are currently no particularly strict standards in China, a 15mm margin is sufficient to meet both the requirements of providing sufficient overhang for wire harness A during maintenance and preventing the terminals from falling off.

[0046] The limitation on the lateral swing angle of the connecting rod 42 is mainly to prevent excessive rotation angle from causing multiple wire harnesses A in the multi-core signal connector plug housing 2 to become entangled and deformed at the end position of the multi-core signal connector plug housing 2. It is compatible with the requirements of resisting radial vibration of wire harness A and anti-entanglement of wire harness A, and at the same time, it is not easy to affect other components of the electrical connector itself. Regarding the vertical swing angle of the connecting rod 42, when it is in the middle or lower position of the linear hole, since the length of the connecting rod 42 is only 12mm and part of it is still inside the housing 41, the swing angle of the multi-core signal connector plug housing 2 will not be particularly large, generally not exceeding 20 degrees. Otherwise, the housing 41 of the multi-core signal connector plug housing 2 will collide with the housing 41 or the substrate 3. Even if the multi-core signal connector plug housing 2 is displaced to the upper position of the linear hole due to vibration, the vertical swing angle of the multi-core signal connector plug housing 2 is only 15 degrees. Therefore, it is possible to avoid the various movements of the multi-core signal connector plug housing 2 caused by vibration affecting other components of the electrical connector itself 1.

[0047] This implementation method can meet the requirements of wiring vibration resistance and wire harness A wiring resistance when used in new energy vehicles, and will not affect the wiring terminals or other components of the electrical connector itself, so that the integration of wire harness A on the electrical connector does not affect the operation of the electrical connector itself.

[0048] Although, in some embodiments, those skilled in the art may design a larger margin of axial float range according to actual needs.

[0049] Furthermore, the pressure plate 45 is connected to the substrate 3 via an elastic member 46. The elastic member 46 includes at least one of a spring and a spring sheet 461. The outer shell 41 includes a frame 412 at one end near the substrate 3 and a limiting frame 413 at the other end. The frame 412 is detachably connected to the substrate 3. After the floating component 4 is assembled, the initial state of the elastic member 46 is a compressed state. The axial section of the frame 412 is rectangular or waist-shaped.

[0050] As an optional implementation of the present invention, the frame 412 with a rectangular or waist-shaped axial section is significant because the connecting rod 42 can automatically reset to the position closest to the outer shell 41. This ensures that the distance between the surface of the outer shell 41 and the surface of the multi-core signal connector plug outer shell 2 is at its maximum. Only in this way can the maximum floating range be provided for the disordered tensile force during vibration, especially the swing angles in the left and right and up and down.

[0051] In some embodiments, the pressure plate 45 is slidably fitted with the inner wall of the frame 412, and the radial section of the frame 412 is rectangular.

[0052] As an optional implementation of the present invention, if the frame 412 is a rectangular frame, in order to ensure that the pressure direction of the pressure plate 45 on the ball head 43 is always forward, the displacement direction of the pressure plate 45 needs to be stable. Therefore, the radial section of the frame 412 is required to be rectangular, and there is a sliding fit between the frame 412 and the pressure plate 45 so that the sliding direction of the pressure plate 45 can remain stable.

[0053] Of course, there are many specific sliding connection methods in the prior art, and this embodiment does not limit them specifically. Preferably, the edge of the pressure plate 45 is provided with a sliding groove, and the inner wall of the frame 412 is provided with a slide rail that cooperates with the sliding groove.

[0054] In some embodiments, the elastic element 46 is a spring sheet 461, and the side wall of the outer shell 41 is also provided with an opening 414 to provide deformation stroke for the spring sheet 461. The end of the spring sheet 461 located outside the outer shell 41 is fixedly connected to the substrate 3.

[0055] As an optional implementation of the present invention, this method, compared with the spring, is more convenient to provide more forward and backward floating stroke for the multi-core signal connector plug housing 2. The main reason is that the part size can be made slightly larger, while if the spring size is too small, the stroke will be insufficient and the elasticity will be insufficient to provide enough reaction force for the pressure plate 45.

[0056] In some embodiments, the base plate 31 is provided with a quick-connect structure 5, which includes at least one of screws and clips.

[0057] As an optional implementation of the present invention, considering the modular integration of wire harness A, generally after the multi-core wire harness A is installed inside the multi-core signal connector plug housing 2, the entire multi-core signal connector plug housing 2 is installed onto the base 1 of the electrical connector. Especially during the maintenance and replacement of battery packs in new energy vehicles, it is necessary to realize the quick disassembly and assembly of the entire multi-core signal connector plug housing 2. Therefore, setting a quick-connect structure 5 on the base plate 31 is more conducive to the disassembly and installation of the entire multi-core signal connector plug housing 2, which is also conducive to the maintenance and replacement of battery packs.

[0058] Example 3 Please see Figure 1 The present invention also provides the following technical solution: a base that supports expansion and integration for mounting terminals in electrical connectors, the base 1 having a plurality of wire holes 11 for wire harness A to pass through, the wire holes 11 being located at positions not covered by the terminals, and the base 1 having mounting positions for mounting substrate 3 near the wire holes 11.

[0059] As an optional implementation of the present invention, the integrated structure of embodiments 1-2 is provided with modularly expandable mounting positions, which makes the wiring operation of various wire harnesses A at the battery pack of new energy vehicles more convenient, and is applicable to battery packs of various models, functions and specifications. User manufacturers can customize the integration of wire harnesses A, which has strong adaptability.

[0060] In some embodiments, the mounting position may be a screw hole or a snap hole corresponding to the quick-connect structure 5.

[0061] Example 4 Please see Figure 1-6 The present invention also provides the following technical solution: an integrated connector, including the above-mentioned wire harness A adaptive integrated structure and a base 1.

[0062] The working principle and usage process of this invention are as follows: During assembly, the multi-core signal connector plug housing 2 is used to fix the wire harness A to be integrated. Then, the connecting rod 42 is passed through the wire hole 411 from the housing 41 and fixed to the multi-core signal connector plug housing 2. Then, the pressure plate 45 is placed into the housing 41 and the housing 41 is installed on the surface of the substrate 3. At this time, the elastic member 46 abuts against the back of the pressure plate 45. Finally, the substrate 3 is installed on the base 1 of the electrical connector to complete the integration of wire harness A.

[0063] When a new energy vehicle is in motion, these wiring harnesses A will vibrate in any direction, which manifests as traction on the wiring harness A along its length. The linear hole 411 provides a sliding path and vertical swing for the ball head 43 and the connecting rod 42. The diameter of the connecting rod 42 is smaller than the width of the linear hole, so the ball head 43 can swing left and right in the lateral direction. With the pressure plate 45 elastically connected inside the housing 41, the ball head 43 can extend and retract in the front and back direction (and the front and back extension and retraction are resettable). Therefore, when the multi-core signal connector plug housing 2 receives vibration from the wiring harness A in any direction, the multi-core signal connector plug housing 2 can swing up and down, left and right, slide up and down, and float back and forth in the housing 41, thus adapting to the vibration force and performing activities within a certain range.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
