Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, specifically a male and female riveting terminal. Background Technology

[0002] Existing male and female rivet terminals are widely used in various electrical connection scenarios. They typically involve male and female terminals being plugged into each other to achieve electrical conduction. Their structure is mostly a rigid plug-in form, that is, the plug-in adopts an integral solid structure, and the plug-in positioning and contact are achieved through the matching of external dimensions.

[0003] However, in practical applications, due to processing errors, assembly deviations or thermal expansion and contraction, there are often certain dimensional tolerances or axial / radial offsets between the connector and the interface, which results in insufficient guidance and large insertion force during the insertion process. In some cases, problems such as failure to insert, jamming, scratches, and structural deformation may occur. In severe cases, it may also lead to poor contact or terminal fatigue damage.

[0004] Furthermore, the lack of a flexible adjustment mechanism during insertion and removal results in rigid insertion, leading to localized stress concentration. This can easily cause physical damage to the female connector and plastic deformation to the male connector, affecting repeated insertion and removal performance and contact stability. Therefore, a male and female rivet terminal is needed to solve these problems. Utility Model Content

[0005] The purpose of this application is to provide a technical solution to address the problems mentioned in the background section.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A male and female riveting terminal includes a male terminal and a female terminal. The male terminal has a connector at its front end and a male riveting portion at its rear end. The female terminal has a connector at its front end and a female riveting portion at its rear end. The connector has at least one male end slit on its side. The male end slit extends from the rear end of the connector toward the front end and expands to the left and right sides at the end to form an arc-shaped opening.

[0008] Preferably, the male terminal also has a male terminal retaining wing.

[0009] Preferably, the female terminal also has a female terminal retaining wing.

[0010] Preferably, the end is in a streamlined arc shape.

[0011] Preferably, a limiting protrusion is provided between the arc-shaped openings formed by the expansion on the left and right sides.

[0012] Preferably, the end face of the limiting protrusion is rectangular, and the side face is fan-shaped.

[0013] Preferably, the side of the insertion interface also has at least one female end opening that matches the male end opening.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] This design provides at least one male end slit extending from the rear end of the connector toward the front end along the insertion direction. The slit expands to the left and right sides at the front end to form arc-shaped openings. This structural design allows the connector to have elastic deformation capability during insertion to adapt to the dimensional tolerances or assembly deviations of the connector interface. At the same time, the left and right arc-shaped openings at the ends of the slit provide flexible buffering and self-alignment guidance during insertion and removal, thereby effectively reducing the insertion force, improving the smoothness and stability of insertion, and avoiding structural fatigue or poor electrical contact caused by stress concentration or metal deformation. It has the advantages of simple structure, good molding consistency, high connection reliability, and suitability for high-frequency insertion and removal. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 A male and female riveting terminal includes a male terminal 1 and a female terminal 2. The male terminal 1 has a connector 11 at its front end and a male riveting portion 12 at its rear end. The female terminal 2 has a connector 21 at its front end and a female riveting portion 22 at its rear end. The connector has at least one male end slit 13 on its side. The male end slit 13 extends from the rear end of the connector 11 toward the front end and expands to the left and right sides at the end to form an arc-shaped opening 14. The connector 11 of this design has at least one male end slit 13 extending from the rear end of the connector 11 toward the front end along the insertion direction. The slit expands to the left and right sides at the front end to form arc-shaped openings 14. This structural design allows the connector 11 to have elastic deformation capability during insertion to adapt to the dimensional tolerances or assembly deviations of the interface 21. At the same time, the left and right arc-shaped openings 14 at the end of the slit provide flexible buffering and self-alignment guidance during insertion and removal, thereby effectively reducing the insertion force, improving the smoothness and stability of insertion, and avoiding structural fatigue or poor electrical contact caused by stress concentration or metal deformation. It has the advantages of simple structure, good molding consistency, high connection reliability, and suitability for high-frequency insertion and removal.

[0024] Preferably, the male terminal 1 further forms a male terminal retaining wing 15. The male terminal retaining wing 15 can mechanically clamp the insulation layer of the wire, which, in addition to achieving the crimping of the conductive core wire, further enhances the overall fixing effect of the cable in the terminal, and prevents the wire from falling off or loosening from the terminal due to tension, vibration or cable swing, thereby effectively improving the tensile strength and long-term stability of the connection. It is particularly suitable for applications in vehicles and industrial control where mechanical stability is required.

[0025] Preferably, the female terminal 2 further comprises a female terminal retaining wing 23. The female terminal retaining wing 23 can clamp the insulating outer sheath of the wire, and while maintaining a stable crimp of the electrical connection, it enhances the overall mechanical fixing strength of the wire and the terminal through a double clamping method, thereby preventing wire shaking or loosening during installation, movement or use, effectively improving the mechanical reliability, wiring life and stress resistance of the female terminal, and is especially suitable for structural protection needs under dynamic load scenarios or high-frequency insertion and removal conditions.

[0026] Preferably, the end portion 15 is a streamlined arc shape. The end portion 15 of the connector 11 is designed as a streamlined arc shape, which facilitates a smooth transition with the female connector during the insertion process. Its arc contour can effectively reduce interference resistance in the initial stage of insertion, making the insertion action smoother and more natural, reducing the insertion force. At the same time, this structure can play a guiding role, so that the plug automatically aligns with the female connector hole, avoiding phenomena such as misalignment, jamming, and metal surface scratching. In addition, the streamlined design can also disperse the local stress concentration caused by the insertion force, which helps to extend the service life of the connector structure and reduce fatigue damage caused by insertion impact.

[0027] Preferably, a limiting protrusion 16 is also provided between the arc-shaped openings 14 formed by the expansion on the left and right sides. The limiting protrusion 16 between the arc-shaped openings 14 can provide precise physical limitation on the insertion depth of the connector. When the insertion action reaches the predetermined position, the end face of the protrusion contacts the female end structure, thereby preventing further insertion and avoiding displacement of the contact area or damage to the internal structure of the female end due to excessive insertion. The setting of the limiting protrusion 16 in this solution not only improves the insertion accuracy, but also enhances the consistency and repeatability of the insertion action, making it suitable for product line applications with high consistency assembly requirements, and helping to improve the reliability and safety of the overall connection system.

[0028] Preferably, the end face of the limiting protrusion 16 is rectangular, and the side face is fan-shaped. The limiting protrusion 16 adopts a composite structure design with a rectangular end face and a fan-shaped side face, which can combine the functions of stopping and guiding in structure. The rectangular end face provides a good limiting contact surface to prevent the plug from being over-inserted, while the fan-shaped side face can gradually fit with the female end structure during the insertion process, playing a role in insertion guidance and buffering transition, thereby reducing mechanical impact and frictional resistance during insertion and removal, avoiding direct hard collision between the plug and the internal structure of the female end, and effectively improving the smoothness of the insertion action, structural durability and contact position stability.

[0029] Preferably, the side of the insertion interface 21 is further formed with at least one female end slit 24 that matches the male end slit 13. Providing at least one female end slit 24 corresponding to the male end slit 13 on the side of the female end insertion interface 21 helps to form a coordinated elastic structure during insertion, allowing the male and female ends to deform in a coordinated manner in the corresponding area during insertion. This adapts to processing errors and assembly tolerances, further reducing insertion force and improving insertion accuracy. Simultaneously, this structure also helps to avoid force concentration or unilateral opening of the male end slit, enhancing the deformation symmetry and mechanical stability of the slit structure, helping to maintain the consistency of the contact area and electrical reliability. It is suitable for use in environments with high insertion / removal frequencies or large temperature fluctuations.
