In the field of new energy vehicles, electrical safety is a key consideration in the design and manufacturing process.

[0003] With the increasing popularity of new energy vehicles, electrical safety issues are becoming more prominent. Traditional grounding terminals require workers to tighten them during assembly. Due to space constraints in the vehicle layout, the connection may become loose or disconnected due to vibration, misoperation, or other reasons, leading to electrical faults or even personal injury. Summary of the Invention

[0004] The purpose of this invention is to provide a self-locking grounding terminal to alleviate the technical problem that traditional grounding terminals require workers to tighten them during assembly. Due to the limited space in the vehicle, the connection may become loose or disconnected due to vibration, misoperation, or other reasons, which could lead to electrical faults or even personal injury.

[0005] The present invention provides a self-locking grounding terminal, including a grounding terminal body, the grounding terminal body having a first through hole, a locking structure provided on the grounding terminal body, and the locking structure having a first through hole concentrically arranged with the first through hole; A limiting member that slides relative to the locking structure is provided on the locking structure. The limiting member has two limiting teeth located on both sides of the first through hole in a first direction. The two limiting teeth cooperate to clamp the stud assembled in the first through hole. The first direction is the sliding direction of the limiting member.

[0006] In an optional embodiment, the limiting member is provided with clamping plates symmetrically arranged along the first direction of the first through hole; a clamping groove is provided on the side of the clamping plate facing the other clamping plate, and the upper end of the clamping groove forms the limiting tooth for inserting into the thread of the stud.

[0007] In an optional embodiment, the two clamping grooves cooperate to form a guide groove, which is used to guide the stud; the longitudinal section of the clamping groove forms an acute angle with the upper end face of the clamping plate.

[0008] In an optional embodiment, the angle between the longitudinal section of the clamping groove and the upper end face of the clamping plate is 78°. In an optional embodiment, the locking structure has a side opening, the side opening forming an upper end plate at the upper end of the locking structure, and an upper protrusion is provided on the lower end surface of the upper end plate. On both sides of the upper protrusion in the first direction, there are upper engagement grooves and upper release grooves; on both sides of the limiting member in the first direction, there are snap-fit ​​protrusions, which can respectively cooperate with the upper engagement grooves and upper release grooves, so that the limiting teeth and the stud can switch between the engagement state and the release state. In an optional embodiment, the side opening forms a lower base plate at the lower end of the locking structure, and a lower protrusion is provided on the upper surface of the lower base plate. A lower engagement groove and a lower release groove are provided on both sides of the lower protrusion in the first direction; the engagement protrusion can cooperate with the lower engagement groove and the lower release groove respectively, so that the limiting tooth and the stud can switch between the engagement state and the release state.

Detailed Implementation

[0016] The terms “first,” “second,” “third,” etc., are used only for distinguishing descriptions and do not indicate a sequence number, nor should they be interpreted as indicating or implying relative importance.

[0017] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They 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. Therefore, they should not be construed as limitations on this application.

[0019] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0020] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0021] Example Reference Figures 1-7 The present invention provides a self-locking grounding terminal, including a grounding terminal body 100, the grounding terminal body 100 having a first through hole, a locking structure 400 provided on the grounding terminal body 100, and the locking structure 400 having a first through hole 600 concentrically arranged with the first through hole; A limiting member 500 that slides relative to the locking structure 400 is provided on the locking structure 400. The limiting member 500 has two limiting teeth 504 located on both sides of the first through hole 600 in a first direction. The two limiting teeth 504 cooperate to clamp the stud 110 assembled in the first through hole 600. The first direction is the sliding direction of the limiting member 500.

[0022] In some embodiments, the grounding terminal body 100 has a first through hole, and the locking structure 400 is disposed on the grounding terminal body 100 and has a first through hole 600; the limiting member 500 is assembled on the locking structure 400. When the stud 110 is inserted from the first through hole into the first through hole 600, the two limiting teeth 504 can clamp the stud 110 and insert it into the thread of the stud 110, so that the locking structure 400 is fixed to the bolt, thereby realizing the self-locking connection between the grounding terminal and the stud 110, and thus realizing grounding.

[0023] When it is necessary to separate the stud 110 from the grounding terminal body 100, the limiting member 500 moves relative to the locking structure 400, so that the limiting tooth 504 can be moved out of the thread gap, and thus the stud 110 can be separated from the locking structure 400.

[0024] This self-locking grounding terminal can reduce the failure rate caused by wiring errors or poor contact; at the same time, the self-locking terminal can provide a more convenient disassembly and assembly experience during vehicle maintenance or parts replacement.

[0025] Figure 4 and Figure 5 In an optional embodiment, the limiting member 500 is provided with a clamping plate 501 symmetrically arranged along the first direction of the first through hole 600; a clamping groove 502 is provided on the side of the clamping plate 501 facing the other clamping plate 501, and the upper end of the clamping groove 502 forms the limiting tooth 504 for inserting into the thread of the stud 110.

[0026] In some embodiments, the limiting member 500 has two clamping plates 501 located on both sides of the first through hole 600, and each clamping plate 501 is provided with a clamping groove 502; the stud 110 can be inserted into the clamping groove 502 from bottom to top, so that the limiting member 500 is not easy to separate from the stud 110, and the strength of the connection between the stud 110 and the locking structure 400 is increased.

[0027] Reference Figure 5 and Figure 7 In an optional embodiment, the two clamping grooves 502 cooperate to form a guide groove 120, which is used to guide the stud 110; the longitudinal section of the clamping groove 502 forms an acute angle with the upper end face of the clamping plate 501.

[0028] In an optional embodiment, the angle between the longitudinal section of the clamping groove 502 and the upper end face of the clamping plate 501 is 78°. During the installation of the self-locking grounding terminal, the guide groove 120 formed by the two clamping grooves 502 can play a guiding role; after the stud 110 is inserted into the first through hole from the lower end of the grounding terminal body 100, the upper end of the stud 110 is inserted into the guide groove 120. The inner diameter of the guide groove 120 gradually decreases from bottom to top, and the guide groove 120 guides the stud 110 to continue to be inserted upwards. This ensures that the stud 110 can be easily inserted into the first through hole 600 and located between the two clamping grooves 502.

[0029] In order to better allow the limiting teeth 504 to be inserted into the gap between the threads of the stud 110, the angle between the longitudinal section of the clamping groove 502 and the upper end face of the clamping plate 501 is 78°; that is, the limiting teeth 504 can be inserted into the stud 110 at a better angle, and the two limiting teeth 504 can better cooperate to clamp the stud 110, so as to prevent the stud 110 from being difficult to separate from the locking structure 400.

[0030] When the self-locking grounding terminal is assembled onto the stud 110, it can effectively serve as a guide, reducing the jamming stress during assembly. At the same time, this angle can better engage and match with the threads on the welded stud 110, achieving a fixed fit.

[0031] Reference Figure 6 In an optional embodiment, the locking structure 400 has a side opening 700, which forms an upper end plate 403 at the upper end of the locking structure 400, and an upper protrusion 401 is provided on the lower end surface of the upper end plate 403. Upper engagement grooves 4012 and upper release grooves 4011 are provided on both sides of the upper protrusion 401 in the first direction; the limiting member 500 is provided with engagement protrusions 503 on both sides of the first direction, and the engagement protrusions 503 can cooperate with the upper engagement grooves 4012 and the upper release grooves 4011 respectively, so that the limiting tooth 504 and the stud 110 can switch between engagement and release states. In an optional embodiment, the side opening 700 forms a lower base plate 404 at the lower end of the locking structure 400, and a lower protrusion 402 is provided on the upper surface of the lower base plate 404. Lower engagement grooves 4022 and lower release grooves 4021 are provided on both sides of the lower protrusion 402 in the first direction; the engagement protrusion 503 can cooperate with the lower engagement grooves 4022 and lower release grooves 4021 respectively, so that the limiting tooth 504 and the stud 110 can switch between engagement and release states. A side support plate 900 is provided between the upper end plate 403 and the lower bottom plate 404. Guide openings 901 are provided on both sides of the side support plate 900 in a first direction, and the guide openings 901 guide the clamping plate 501 to move.

[0032] When the self-locking grounding terminal is connected to the stud 110, the locking protrusion 503 is located in the upper engagement groove 4012 and the lower engagement groove 4022. When it is necessary to separate the self-locking grounding terminal from the stud 110, the locking protrusion 503 is moved out of the lower engagement groove 4022 and moved downward to the release groove 4021 and locked in the lower release groove 4021 by moving the limiting member 500. At this time, the locking structure 400 of the self-locking grounding terminal can be separated from the stud 110, which facilitates subsequent maintenance and repair.

[0033] The upper end plate 403 of the side opening 700 of the locking structure 400 has an upper protrusion 401, and the lower bottom plate 404 has a lower protrusion 402. A side clamping groove 502 is formed between the upper protrusion 401 and the lower protrusion 402, and the guide opening 901 communicates with the side clamping groove 502. The clamping plate 501 is inserted into the side clamping groove 502 from the guide opening 901. The upper protrusion 401 and the lower protrusion 402 cooperate to restrict the up and down movement of the clamping plate 501, so that the clamping plate 501 can move precisely.

[0034] To prevent the limiting member 500 from easily separating from the locking structure 400, an upper release groove 4011 is provided on the upper protrusion 401, and a lower release groove 4021 is provided on the lower protrusion 402. When the limiting teeth 504 of the limiting member 500 do not engage with the stud 110, the limiting member 500 moves away from the stud 110 until the engaging protrusion 503 is respectively engaged in the upper release groove 4011 and the lower release groove 4021, thus preventing the limiting member 500 from separating from the locking structure 400.

[0035] In an optional embodiment, a rubber liner 800 is provided on the lower end face of the upper end plate 403 or the upper end face of the lower bottom plate 404, and the rubber liner 800 is used to fill the gap between the upper end plate 403 and the limiting member 500.

[0036] In some embodiments, a rubber liner 800 is provided on the lower end surface of the upper end plate 403. The rubber liner 800 can increase the friction between the limiting member 500 and the locking structure 400, making the limiting member 500 less prone to shaking, effectively increasing the firmness of the connection between the limiting member 500 and the bolt, and effectively preventing the connection between the limiting member 500 and the bolt from loosening due to vibration, thereby causing electrical faults or even personal injury.

[0037] Reference Figure 1 and Figure 2 In an optional embodiment, the grounding terminal body 100 is provided with at least one terminal limiting structure 300 and at least one terminal connection structure 200. In an optional embodiment, one end of the grounding terminal body 100 is provided with a terminal limiting structure 300, and the other end is provided with a terminal connection structure 200.

[0038] In some embodiments, in order to securely fix the grounding terminal body 100, one or more terminal limiting structures 300 are provided on the grounding terminal body 100; in order to enable the grounding terminal body 100 to be connected to the grounding wire at the same time, multiple terminal connection structures 200 may be provided on the grounding terminal body 100; when the grounding terminal body 100 is provided with only one terminal connection structure 200 and a terminal limiting structure 300, one end of the grounding terminal body 100 is provided with a terminal connection structure 200 and the other end is provided with a terminal limiting structure 300.

[0039] The limiting component 500 is matched with the locking structure 400 to achieve the effect of positioning and assembly. In the actual assembly process, the terminal limiting structure 300 is matched with the limiting opening on the vehicle body.

[0040] In an optional embodiment, the terminal connection structure 200 includes a wrapping sheet 201 and an arc-shaped plate 202. The wrapping sheet 201 is connected to the grounding terminal body 100. The arc-shaped plate 202 is provided on the side of the wrapping sheet 201 away from the first through hole, and fixing plates 203 are provided on both sides of the arc-shaped plate 202.

[0041] Anti-slip grooves can be provided on both the wrapping sheet 201 and the arc plate 202. The anti-slip grooves can improve the anti-slip performance of the surface of the terminal connection structure 200, thereby improving the firmness of the connection between the terminal connection structure 200 and the grounding wire, and thus effectively improving the stability of the connection between the grounding wire and the self-locking grounding terminal.

[0042] The grounding terminal body 100, the wrapping piece 201, the arc plate 202 and the fixing plate 203 are integrally formed, which can improve the strength of the entire self-locking grounding terminal, thereby improving the tensile strength and anti-deformation performance of the self-locking grounding terminal and improving the safety of using the self-locking grounding terminal.

[0043] The limiting member 500 of the locking structure 400 of the self-locking grounding terminal provided by the present invention can move relative to the locking structure 400. When the stud 110 is inserted into the first through hole 600 from the first through hole, the limiting teeth 504 on the limiting member 500 can be inserted into the gap between adjacent threads of the stud 110, so that the limiting member 500 is firmly connected to the stud 110. When it is necessary to separate the stud 110 from the grounding terminal body 100, the limiting member 500 moves relative to the locking structure 400, so that the limiting teeth 504 can be moved out from the gap of the threads, and then the stud 110 can be separated from the locking structure 400. This self-locking grounding terminal can reduce the failure rate caused by wiring errors or poor contact; at the same time, the self-locking terminal can provide a more convenient disassembly and assembly experience during vehicle maintenance or parts replacement.

[0044] Self-locking grounding terminals provide reliable electrical grounding, ensuring that vehicles can quickly and accurately connect their circuits to the ground, preventing electric shock and circuit overload, thus protecting the safety of passengers and the vehicle. Self-locking grounding terminals with a self-locking function can greatly simplify the assembly process of new energy vehicles, reducing the failure rate caused by wiring errors or poor contact. At the same time, during vehicle maintenance or component replacement, self-locking grounding terminals provide a more convenient disassembly and assembly experience. They ensure stable connections under harsh environmental conditions, preventing circuit interruptions and safety hazards caused by loose terminals, and guaranteeing continuous vehicle operation.

[0045] The self-locking grounding terminal's self-locking function ensures a stable connection under all conditions, effectively preventing circuit disconnection even during vehicle collisions or severe vibrations. This avoids electrical fires and electric shock risks, significantly enhancing vehicle safety. Simultaneously, this design simplifies the installation and removal process, requiring no additional tools and greatly reducing maintenance costs and time. It also reduces the failure rate due to improper operation, improving vehicle maintainability. Through optimized design, the self-locking grounding terminal reduces material and manufacturing costs while maintaining high performance, minimizing long-term maintenance and replacement expenses, providing a more cost-effective solution for new energy vehicle manufacturers and consumers.

[0046] Self-locking grounding terminals not only improve the safety and reliability of new energy vehicles, but also optimize production and maintenance processes, bringing significant technological progress and economic benefits to the development of the new energy vehicle industry.
