Abstract
Description
Technical Field

[0002] Currently, connectors are used in automotive products to maintain electrical connections between various components. The reliability of the connector terminal structure affects the overall safety and stability of the vehicle. Existing connectors consist of terminals and a sheath. The terminal is typically inserted into the sheath and secured within it by a spring-loaded arm structure. However, during assembly, the spring-loaded arm structure can rub against other components, causing it to compress. This reduces the tightness of the connection between the terminal and the sheath after installation, creating a risk of loosening. Utility Model Content

[0004] To achieve the above objectives, according to a first aspect of this application, a terminal is provided, comprising: a body;
[0005] A resilient snap-fit portion is provided on the main body. The resilient snap-fit portion includes a plurality of sequentially connected bent segments, each bent segment extending in a direction away from the main body. The resilient snap-fit portion is used to engage with the sheath to limit the position of the terminal relative to the sheath.
[0006] Optionally, the elastic snap-fit portion includes a first bent section and a second bent section connected in sequence, with the first bent section located close to the main body.
[0007] Optionally, the resilient snap-fit portion further includes a third bend, which is located at the end of the second bend that is furthest from the first bend.
[0008] Optionally, the angle between the extension direction of the first bending segment and the length direction of the main body is α, where 0 < α < 90°.
[0009] Optionally, the angle between the extension direction of the second bending segment and the length direction of the main body is β, where α < β < 90°.
[0010] Optionally, the angle between the extension direction of the third bending segment and the length direction of the main body is γ, where 0.5γ≤α≤1.5γ.
[0011] Optionally, the elastic snap-fit portion further includes a protrusion, with a first protrusion provided at the connection between the first bent segment and the second bent segment; and / or, a second protrusion provided at the connection between the second bent segment and the third bent segment.
[0012] Optionally, the first protrusion extends along the elastic snap-fit portion toward the body.
[0013] Optionally, the second protrusion extends along the side of the elastic snap-fit portion away from the main body.
[0014] Optionally, the main body also includes a bottom wall, two side walls connected to both sides of the bottom wall, and a top wall connected to the top of the side walls, with the elastic snap-fit part disposed on the side of the top wall away from the bottom wall.
[0015] Optionally, the main body also includes a reinforcing member, which is disposed above the top wall. One end of the reinforcing member is connected to the first bent section, and the other end of the reinforcing member is connected to the top wall.
[0016] Optionally, the bottom wall, the two side walls, and the side of the top wall away from the elastic snap-fit portion cooperate to form a mating opening. The distance from the connection between the elastic snap-fit portion and the top wall to the mating opening of the main body in the length direction of the main body is L1, and the extension length of the reinforcing member in the length direction of the main body is L2, where L1 < L2.
[0017] Optionally, the distance between the top wall of the reinforcing member and the bottom wall of the main body is H1. The main body also includes a support portion located on the side of the elastic snap-fit portion away from the insertion port of the main body.

[0018] Optionally, the reinforcement is welded to the top wall.
[0019] Optionally, the main body also includes a shielding part, which is connected to the end of the top wall away from the elastic snap-fit part to shield the gap between the top wall and the side wall.

The elastic snap-fit portion includes multiple sequentially connected bent segments, each bent segment extending away from the main body. The elastic snap-fit portion is used to snap-fit with a sheath to limit the position of the terminal relative to the sheath. By setting the elastic snap-fit portion as multiple sequentially connected bent segments, the force points of the elastic snap-fit portion can be dispersed during the assembly process of the elastic snap-fit portion and the sheath, thereby appropriately reducing the lever arm of the elastic snap-fit portion and increasing the force required for the elastic snap-fit portion to deform, thereby reducing the deformation amount of the elastic snap-fit portion and improving the connection tightness between the terminal and the sheath.

Detailed Implementation
[0033] 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 protection scope of this application.
[0034] like Figures 1 to 5According to a first aspect of this application, a terminal is provided, comprising: a body 10; and a resilient snap-fit portion 20 disposed on the body 10, the resilient snap-fit portion 20 comprising a plurality of sequentially connected bent segments, each bent segment extending in a direction away from the body 10, the resilient snap-fit portion 20 being used to snap-fit with a sheath to limit the position of the terminal relative to the sheath.
[0035] By using the above technical solution, the elastic snap-fit part 20 is configured as a plurality of sequentially connected bent sections. During the assembly process of the elastic snap-fit part 20 and the sheath, the stress points of the elastic snap-fit part 20 can be dispersed, thereby appropriately reducing the lever arm of the elastic snap-fit part 20 and increasing the force required when the elastic snap-fit part 20 deforms. This reduces the amount of deformation of the elastic snap-fit part 20 and improves the connection tightness between the terminal and the sheath.
[0036] Optionally, the resilient snap-fit portion 20 includes a first bent section 21 and a second bent section 22 connected in sequence, with the first bent section 21 disposed close to the main body 10. This means that the first bent section 21 is a bridge connecting the main body 10 and other bent sections, and the second bent section 22, as a component of the resilient snap-fit portion 20, works in conjunction with the first bent section 21 to achieve specific functions, such as providing additional support, stability, or elasticity.
[0037] Optionally, the resilient snap-fit portion 20 further includes a third bent section 23, which is located at the end of the second bent section 22 away from the first bent section 21. By providing the above structure, the third bent section 23 can contact the sheath to fix the terminal to the sheath, thereby further ensuring the stability of the resilient snap-fit portion 20 when it snaps into the sheath.
[0038] Optionally, the angle between the extension direction of the first bent segment 21 and the length direction of the main body 10 is α, where 0 < α < 90°. Simultaneously, the first bend and the length direction of the main body 10 have an angle α, which ranges from 0° to 90°, but excludes 0° and 90°. This design allows the first bent segment 21 to have a certain degree of inclination, and such an angle design is typically used to increase the flexibility or adaptability of the structure. For example, when subjected to external forces, this inclination design allows the first bent segment 21 to undergo a certain degree of deformation, thereby absorbing energy or providing necessary elasticity. The second bent segment 22, as a component of the elastic latching part 20, works in conjunction with the first bent segment 21 to achieve specific functions, such as providing additional support, stability, or elasticity. In embodiments of this application, α can be set to 30°, 60°, or 70°.
[0039] Optionally, the angle between the extension direction of the second bending segment 22 and the length direction of the main body 10 is β, where α < β < 90°. When the angle between the extension direction of the second bending segment 22 and the length direction of the main body 10 is β, and the condition α < β < 90° is satisfied, this design has the following advantages: Increased elasticity and adaptability: Since the β angle is greater than the α angle, the inclination of the second bending segment 22 relative to the main body 10 is greater, which increases the elasticity of the entire elastic snap-fit portion 20. When subjected to external force, this design allows the second bending segment 22 to undergo greater deformation, thereby absorbing more energy and improving the adaptability and durability of the structure. By adjusting the angles α and β, the stress distribution inside the elastic snap-fit portion 20 can be optimized. A larger β angle may help to distribute stress more evenly throughout the structure, reducing the risk of local stress concentration and thus extending the service life of the structure. Although the inclination of the second bending segment 22 is increased, this does not mean a decrease in connection stability.
[0040] Conversely, through a reasonable angle design, the elastic snap-fit part 20 can be ensured to remain stable under external force, preventing it from easily falling off or being damaged. This design is particularly suitable for applications requiring high stability and reliability. Different combinations of α and β angles can give the elastic snap-fit part 20 different functions and characteristics. For example, by adjusting these angles, more complex connection structures can be achieved to meet specific installation or connection requirements. This versatility makes the elastic snap-fit part 20 widely applicable in various application scenarios. In some cases, adjusting the angles α and β can simplify the manufacturing process of the elastic snap-fit part 20. For example, by selecting a suitable angle combination, processing steps can be reduced or the requirements for manufacturing precision can be lowered, thereby reducing production costs and improving production efficiency. In the embodiments of this application, α and β can be set to 30°, 60°, or 70°.
[0041] Optionally, the angle between the extension direction of the third bending segment 23 and the length direction of the main body 10 is γ, where 0.5γ ≤ α ≤ 1.5γ. During manufacturing, if the angle between the third bending segment 23 and the first bending segment 21 is equal, the same tools, molds, or equipment can be used to manufacture both the third bending segment and the first bending segment 21, thereby improving production efficiency and reducing costs. Standardized angles also help reduce scrap rates and improve product quality. In some cases, maintaining a consistent angle between the bending segment and the main body 10, i.e., α = γ, can enhance the overall stability and strength of the structure, which is particularly important for applications requiring heavy loads or high stress.
[0042] Optionally, the elastic snap-fit portion 20 further includes a protrusion 24, with the first protrusion 24 provided at the connection between the first bent section 21 and the second bent section 22; and / or, the second protrusion 24 provided at the connection between the second bent section 22 and the third bent section 23. By setting the above structure, the strength of the root of the force-bearing point of the elastic snap-fit portion 20 can be improved, thereby effectively increasing the positive force of the elastic snap-fit portion 20 pressing down. This can effectively reduce the potential risk of insufficient holding force between the elastic snap-fit portion 20 and the sheath mounting platform due to improper operation by employees hitting the elastic snap-fit portion 20 during actual production and processing.
[0043] Optionally, the first protrusion 24 extends along the side of the resilient locking portion 20 toward the main body 10. This arrangement allows the protrusion 24 to engage more tightly with the resilient locking portion 20 when bent toward it, thereby increasing the stability of the connection. This design helps prevent the connection from loosening or detaching under vibration or impact conditions. The tight fit between the protrusion 24 and the resilient locking portion 20 helps to distribute stress, thereby enhancing the strength of the entire structure.
[0044] Optionally, the second protrusion 24 extends along the side of the elastic snap-fit portion 20 away from the main body 10. This arrangement helps to increase the stability of the connection between the second bent section 22 and the third bent section 23, thereby preventing the second bent section 22 and the third bent section 23 from loosening or falling off under vibration or impact conditions.
[0045] Optionally, the main body 10 also includes a bottom wall 11, two side walls 12 connected to both sides of the bottom wall 11, and a top wall 13 connected to the top of the side walls 12, with the elastic snap-fit portion 20 disposed on the top wall 13. By setting the above structure, not only is the overall layout of the terminal more compact, but the space occupied by the elastic snap-fit portion 20 is also reduced, thereby facilitating the miniaturization of the terminal.
[0046] Optionally, the main body 10 also includes a reinforcing member 30, which is disposed above the top wall 13. One end of the reinforcing member 30 is connected to the first bent section 21, and the other end of the reinforcing member 30 is connected to the top wall 13. By setting the above structure, the force-bearing point of the elastic locking part 20 can be moved forward, thereby shortening the lever arm and thickening the wall at the root of the force-bearing point of the elastic locking part 20, making it stronger, thereby increasing the holding force.
[0047] Optionally, the distance between the connection point of the elastic locking part 20 and the top wall 13 and the insertion port of the main body 10 in the length direction of the main body 10 is L1, and the extension length of the reinforcing member 30 in the length direction of the main body 10 is L2, where L1 < L2. This ensures that the force-bearing point of the elastic locking part 20 is moved forward, thereby shortening the lever arm and increasing the holding force.
[0048] Optionally, the distance between the top wall of the reinforcing member 30 and the bottom wall of the main body 10 is H1. The main body 10 also includes a support portion 14, which is located on the side of the elastic snap-fit portion 20 away from the mating opening of the main body 10. The distance between the top wall of the support portion 14 and the bottom wall of the main body 10 is H2, where H1 ≤ H2. This ensures that the terminals and sheaths do not interfere with each other during installation, thus guaranteeing that the terminals can be smoothly assembled into the sheath holes and improving the assembly efficiency between the terminals and sheaths.
[0049] Optionally, the reinforcing member 30 is welded to the top wall 13. The welded connection, formed by fusion welding the reinforcing member 30 to the top wall 13, possesses high strength and can withstand large loads. Simultaneously, the weld seam effectively transfers stress, maintaining the overall stability of the structure. Furthermore, it eliminates the need for bolts, rivets, or other fasteners, saving material usage. The welded connection directly links the reinforcing member 30 to the top wall 13 without additional processing steps, reducing manufacturing costs. The welded connection can be used for partial or overall connection as needed, offering significant flexibility.
[0050] Optionally, the main body 10 also includes a shielding part 31, which is connected to one end of the top wall 13 away from the elastic snap-fit part 20 to shield the gap between the top wall 13 and the side wall 12. By providing the above structure, it is possible to prevent external debris from entering the gap between the top wall 13 and the side wall 12, thereby helping to ensure the normal use of the device.
[0051] According to a second aspect of this application, a connector is provided, including the terminals described above.
[0052] According to a third aspect of this application, a connector as described above is also provided.
[0053] The terminal in this embodiment includes: a main body 10; and an elastic snap-fit portion 20 disposed on a top wall 13. The elastic snap-fit portion 20 includes multiple sequentially connected bent segments, each extending away from the main body 10. The elastic snap-fit portion 20 is used to snap-fit with a sheath to limit the position of the terminal relative to the sheath. By setting the elastic snap-fit portion 20 as multiple sequentially connected bent segments, the force points of the elastic snap-fit portion 20 can be dispersed during the assembly process of the elastic snap-fit portion 20 and the sheath, thereby appropriately reducing the lever arm of the elastic snap-fit portion 20 and increasing the force required for the elastic snap-fit portion 20 to deform, thereby reducing the amount of deformation of the elastic snap-fit portion 20 and improving the connection tightness between the terminal and the sheath.
