Description

Technical Field

[0001] This application belongs to the field of connector technology, specifically relating to a connector, a vehicle wiring harness, and a vehicle. Background Technology

[0002] Existing connectors on the market are all single-latch devices with limited functionality, only ensuring a locking action when the male and female connectors are properly aligned. However, vehicle connectors increasingly require operation at high voltages. Current connectors, with their single-latch mechanism, require a seamless mating and disassembly process, leaving insufficient reaction time for the vehicle's electrical system. This can lead to connector arcing, poor contact, and other issues. Utility Model Content

[0003] Purpose of the utility model: The embodiments of this application provide a connector, a vehicle wiring harness, and a vehicle, aiming to solve the problem of the limited functionality of existing connector latches.

[0004] Technical solution: A connector according to an embodiment of this application includes:

[0005] The male end includes a first body, a first limiting block and a second limiting block, both of which are connected to the first body;

[0006] The mother end includes a second body, a first locking structure, and a second locking structure, both of which are connected to the second body.

[0007] Specifically, when the male end and the female end are mated and connected, the first locking structure abuts against the first limiting block; when the female end moves a first preset distance axially toward the direction of separation from the male end, the second locking structure abuts against the second limiting block.

[0008] Accordingly, embodiments of this application also provide a vehicle wiring harness, including a cable and a connector as described above.

[0009] Accordingly, embodiments of this application also provide a vehicle, including a body and a connector as described above.

[0010] Beneficial Effects: Compared with the prior art, the connector in this embodiment includes: a male end comprising a first body, a first limiting block, and a second limiting block, both connected to the first body; and a female end comprising a second body, a first locking structure, and a second locking structure, both connected to the second body. When the male and female ends are mated, the first locking structure abuts against the first limiting block to prevent the female end from accidentally disengaging. When the female end moves axially a first preset distance in the direction of disengagement from the male end, the second locking structure abuts against the second limiting block. The first preset distance needs to be set according to actual needs, ensuring that the female end unlocks the first locking structure so that no electric arc is generated during the process of the female end disengaging from the male end. The female end of the connector pauses during disengagement, allowing the system circuit sufficient time to complete the power-on / off operation of the connector, preventing arc erosion.

[0011] Compared with the prior art, a vehicle wiring harness according to an embodiment of this application includes the connector described above. It is understood that the vehicle wiring harness may have all the technical features and effects of the connector described above, which will not be repeated here.

[0012] Compared with the prior art, a vehicle according to an embodiment of this application includes the connector described above. It is understood that the vehicle can have all the technical features and effects of the connector described above, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular, for example, the range of included angles between 80° and 100° is considered perpendicular. Similarly, "parallel" means completely parallel or almost completely parallel, for example, the range of completely parallel angles between 10° is considered parallel.

[0024] In related technologies, connectors used under high-voltage conditions pose a significant safety hazard. When a user directly unplugs the connector during charging, the vehicle's electrical system may not promptly cut off the current. In this case, because the current is still flowing, an electric arc is generated. An electric arc is a high-temperature, bright discharge phenomenon that not only causes ablation and damage to the connector surface but may also trigger more serious electrical faults, affecting the stability and safety of the vehicle's electrical system. To address this issue, the applicant proposes an improved connector design. This innovation not only increases the connector's lifespan but also enhances the overall safety of electric vehicles. Through these improvements, the applicant hopes to significantly reduce equipment damage caused by electric arcs and provide electric vehicle users with a safer and more reliable charging experience.

[0025] In view of this, embodiments of this application provide a connector designed to overcome at least one of the aforementioned technical problems.

[0026] Please see Figures 1 to 4 The connector in this embodiment includes:

[0027] The male end 2 includes a first body 21, a first limiting block 22 and a second limiting block 23, both of which are connected to the first body 21;

[0028] The female end 1 includes a second body 11, a first locking structure 12 and a second locking structure 13, both of which are connected to the second body 11.

[0029] In this configuration, when the male terminal 2 and female terminal 1 are mated and connected, the first locking structure 12 abuts against the first limiting block 22 to prevent the female terminal 1 from accidentally disengaging. When the female terminal 1 moves a first preset distance along the axial direction X towards the direction of separation from the male terminal 2, the second locking structure 13 abuts against the second limiting block 23. The first preset distance needs to be set according to actual needs, ensuring that the female terminal 1 unlocks the first locking structure 12 so that no electric arc is generated during the process of the female terminal 1 disengaging from the male terminal 2. The connector female terminal 1 is designed with a pause action when disconnecting to ensure that the entire vehicle system circuit has sufficient time to complete the power-off process of the connector. This design effectively prevents arcing caused by current interruption, thereby protecting the integrity and safety of the connector and related circuits. This pause action provides a buffer time, reducing the risk of arcing during disconnection and extending the connector's service life. Through this improved design, the stability and safety of the entire vehicle system are also significantly improved.

[0030] Please see Figure 2 , Figure 5 In some embodiments, the second limiting block 23 includes a second limiting surface 231; the second locking structure 13 includes a second locking surface 1321, and the second limiting surface 231 can abut against the second locking surface 1321 along the axial direction X for limiting. Through the large-area abutment between the second limiting surface 231 and the second locking surface 1321, the second locking structure 13 has a stable and reliable locking effect.

[0031] Please see Figure 4 , Figure 5 In some embodiments, the second locking structure 13 includes: a second connecting portion 131 connected to the second body 11; a second locking block 132 connected to the second connecting portion 131, the second locking block 132 including a second locking surface 1321; and a second pressing block 133 disposed on the side of the second connecting portion 131 away from the second locking block 132 and connected to the second connecting portion 131.

[0032] When the end of the second pressing block 133 away from the second connecting part 131 moves in a direction close to the second body 11, the end of the second locking block 132 away from the second connecting part 131 moves in a direction away from the second body 11. By pressing the second pressing block 133, the second locking block 132 can be moved, causing the second locking surface 1321 and the second limiting surface 231 to disengage, thereby releasing the locking of the second locking structure 13.

[0033] In this embodiment, the second locking structure 13 is integrally manufactured from the same material as the second body 11. An elastic material is selected, and by utilizing the elasticity of the material itself, the second locking block 132 can move away from the second body 11 after the second pressing block 133 is pressed, and it can also reset. In other embodiments, other structures with the same function can also be provided. For example, the second connecting part 131 can be a pivot hinged to the second body 11, and the second pressing block 133 and the second locking block 132 can be integrally connected. An elastic element, such as a torsion spring sleeved outside the pivot, or a spring fixed between the second body 11 and the second pressing block 133 or the second locking block 132, can be used to reset the second locking block 132.

[0034] Please see Figure 2 , Figure 5 In some embodiments, the second limiting block 23 is provided with a second guide surface 232, and the second locking block 132 is provided with a second sliding surface 1322 adapted to the second guide surface 232. During the mating process of the female end 1 and the male end 2, the second guide surface 232 abuts against the second sliding surface 1322, so that the end of the second locking block 132 away from the second connecting part 131 moves in a direction away from the second body 11, so that the second locking structure 13 will not hinder the mating process during the mating process.

[0035] Please see Figure 2 , Figure 5 In some embodiments, the first limiting block 22 includes a first limiting surface 221; the first locking structure 12 includes a first locking surface 1221, and the first limiting surface 221 can abut against the first locking surface 1221 along the axial direction X for limiting. Through the large-area abutment between the first limiting surface 221 and the first locking surface 1221, the first locking structure 12 has a stable and reliable locking effect.

[0036] Please see Figure 4 , Figure 5 In some embodiments, the first locking structure 12 includes: a first connecting portion 121 connected to the second body 11; a first locking block 122 connected to the first connecting portion 121, the first locking block 122 including a first locking surface 1221; and a first pressing block 123 disposed on the side of the first connecting portion 121 away from the first locking block 122 and connected to the first connecting portion 121.

[0037] When the end of the first pressing block 123 away from the first connecting part 121 moves in a direction close to the second body 11, the end of the first locking block 122 away from the first connecting part 121 moves in a direction away from the second body 11. By pressing the first pressing block 123, the first locking block 122 can be moved, causing the first locking surface 1221 and the first limiting surface 221 to disengage, thereby releasing the locking of the first locking structure 12.

[0038] In this embodiment, the first locking structure 12 and the second body 11 are still integrated into one structure. Of course, other forms of the first locking structure 12 can also be used, which will not be described in detail here. It should be noted that in order to prevent the female end 1 from being directly disengaged from the male end 2 at one time, the first pressing block 123 and the second pressing block 133 cannot be set as an integrated connection.

[0039] Please see Figure 2 , Figure 5 In some embodiments, the first limiting block 22 is provided with a first guide surface 222, and the first locking block 122 is provided with a first sliding surface 1222 adapted to the first guide surface 222. During the mating process of the female end 1 and the male end 2, the first guide surface 222 abuts against the first sliding surface 1222, so that the end of the first locking block 122 away from the first connecting part 121 moves in a direction away from the second body 11, so that the first locking structure 12 will not hinder the mating process during the mating process.

[0040] Please see Figure 3 , Figure 6 In some embodiments, the male end 2 further includes a third limiting block 24, which is connected to the first body 21; the female end 1 further includes a third locking structure 14, which is connected to the second body 11. When the female end 1 moves a second preset distance along the axial direction X towards the male end 2, and the female end 1 and male end 2 are not yet fully mated, the third locking structure 14 abuts against the third limiting block 24. The second preset distance needs to be set according to actual needs, ensuring that no electric arc is generated when the female end 1 is about to be fully mated with the male end 2. The designed third locking structure 14 can temporarily stop the mating process within a safe distance. This design not only ensures safety during the mating process but also effectively prevents arc erosion caused by improper operation. With this design, users can connect equipment with greater confidence, reducing maintenance and repair needs and extending the service life of the equipment. It also optimizes the stability and reliability of the connection operation, making it particularly suitable for connecting high-voltage electrical equipment.

[0041] Please see Figure 3 , Figure 6 In some embodiments, the third limiting block 24 includes a third limiting surface 241; the third locking structure 14 includes a third locking surface 1421, and the third limiting surface 241 can abut against the third locking surface 1421 along the axial direction X for limiting. Through the large-area abutment between the third limiting surface 241 and the third locking surface 1421, the third locking structure 14 has a stable and reliable locking effect.

[0042] Please see Figure 4 , Figure 6In some embodiments, the third locking structure 14 includes: a third connecting portion 141 connected to the second body 11; a third locking block 142 connected to the third connecting portion 141, the third locking block 142 including a third locking surface 1421; and a third pressing block 143 disposed on the side of the third connecting portion 141 away from the third locking block 142 and connected to the third connecting portion 141.

[0043] When the end of the third pressing block 143 away from the third connecting part 141 moves in a direction close to the second body 11, the end of the third locking block 142 away from the third connecting part 141 moves in a direction away from the second body 11. By pressing the third pressing block 143, the third locking block 142 can be moved, causing the third locking surface 1421 and the third limiting surface 241 to disengage, thereby releasing the locking of the third locking structure 14.

[0044] In this embodiment, the first locking structure 12 and the second body 11 are still integrated into one structure. Of course, other forms of the first locking structure 12 can also be used, which will not be described in detail here. The first locking structure 12, the second locking structure 13, the third locking structure 14, and the second body 11 are integrated into one structure, which can be formed in one go, effectively reducing the assembly process of the split structure.

[0045] Please see Figure 3 , Figure 6 In some embodiments, the third limiting block 24 is provided with a third guide surface 242, and the third locking block 142 is provided with a third sliding surface 1422 adapted to the third guide surface 242. During the separation of the female end 1 and the male end 2, the third guide surface 242 abuts against the third sliding surface 1422, so that the end of the third locking block 142 away from the third connecting part 141 moves in a direction away from the second body 11, so that the third locking structure 14 will not obstruct the pulling process during the pulling out of the female end 1.

[0046] In this embodiment, the second pressing block 133 and the third pressing block 143 are integrally connected, allowing both functions to be achieved with a single pressing block during the disengagement and mating processes. In this embodiment, the second connecting portion 131 and the third connecting portion 141 have parallel axes and are respectively located on both sides of the second body 11. In other embodiments, for example, when a rotating shaft is used as the second connecting portion 131 and the third connecting portion 141, the second connecting portion 131 and the third connecting portion 141 can be integrally connected, meaning the second connecting portion 131 and the third connecting portion 141 share the same rotating shaft.

It is understood that this vehicle wiring harness may possess all the technical features and effects of the connector described above, and will not be repeated here.
