[0002] In electrical engineering, terminals often refer to wiring terminals, also called wiring terminals. They are classified into single-hole, double-hole, plug, and hook types, and in terms of materials, they include silver-plated copper, zinc-plated copper, copper, aluminum, and iron. Their main function is to transmit electrical signals or conduct electricity.

[0003] Chinese patent CN210607644U discloses a high current-carrying crimped connector terminal, comprising a terminal body with two crimping plates connected by an arc-shaped bottom. The arc-shaped bottom is connected to a flat plate, which has a boss. The crimping plates, arc-shaped bottom, flat plate, and boss are integrally formed. A liner is provided on the terminal body, comprising an arc-shaped bottom liner and a flat liner. The arc-shaped bottom liner rests against the inner side of the arc-shaped bottom, and the flat liner rests against the flat plate. The flat liner has a circular hole, and the boss is fixedly connected to the circular hole. A mounting hole is formed at the center of the boss. The thickness of the crimping plates and the arc-shaped bottom is 2 mm. This crimped connector terminal is less prone to tearing during the crimping process, which helps ensure crimping quality. The liner also acts as a conductor, ensuring sufficient cross-sectional area for current flow, thus improving the current-carrying capacity of the crimped connector terminal.

[0004] However, the locking part of the terminal in this technical solution is not stable enough. When it is inserted into the designated component, it will wobble, resulting in instability and poor firmness of the entire terminal. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a precision riveting type snap-fit ​​terminal. By installing a connecting sleeve at the end of the snap-fit ​​part, the snap-fit ​​part becomes more stable and secure, thus solving the problem of easy shaking when installing individual terminals in existing technologies.

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

[0007] A precision riveting type snap-fit ​​terminal includes: a snap-fit ​​part and a connecting sleeve fixedly connected to the snap-fit ​​part. The first end of the snap-fit ​​part is formed by two layers of metal plates being tightly stacked and riveted together. The end of the snap-fit ​​part is hollow inside and has a groove formed to be adapted for installation with the terminal connecting component.

[0028] Example

[0029] like Figure 1-4As shown, this embodiment provides a precision riveting type snap-fit ​​terminal, including: a snap-fit ​​part 1 and a connecting sleeve 2 fixedly connected to the snap-fit ​​part 1. The first end of the snap-fit ​​part 1 is formed by two layers of metal plates 11 tightly stacked and riveted together. A slot 12 adapted to the terminal connection component is formed between the snap-fit ​​part 1 and the connecting sleeve 2. The connecting sleeve 2 enhances the stability of the snap-fit ​​part 1 when snapped together, and the riveting can ensure the strength of the terminal, making it more stable. The riveting process is fast, the production efficiency is high, and it is suitable for mass production. Furthermore, the riveting process can reduce material waste and lower costs.

[0030] The buckle part 1 is integrally stamped, meaning it is a non-removable component. This makes the structure more stable and robust, with better durability. The integral molding eliminates the time and cost of assembling multiple components, reducing material, labor, and energy consumption during the manufacturing process, thereby lowering the overall cost.

[0031] Meanwhile, the connecting sleeve 2 is fitted onto the outer surface of the end of the buckle part 1, and the shape of the connecting sleeve 2 is adapted to the shape of the end of the buckle part 1. The connecting sleeve 2 is used to reinforce the buckle groove 12 to ensure that the buckle part 1 is more stable and firm, thereby making the entire terminal more secure and preventing shaking, thus ensuring the quality and reliability of signal transmission.

[0032] In this embodiment, the snap-fit ​​part 1 and the connecting sleeve 2 are formed by ultrasonic welding. The ultrasonic welding process is very fast, usually completed within a few seconds, which improves the production efficiency of the terminals. Unlike traditional welding, ultrasonic welding does not require the use of adhesives or solvents, so it is more environmentally friendly and cleaner, and pollution-free. It can also control the welding position and strength very precisely, making it suitable for connecting precision components. It also does not require special welding tools or molds, reducing production costs. Furthermore, no preheating is required during the ultrasonic welding process, saving energy and time. Ultrasonic welding is easy to integrate into automated production lines, facilitating the mass production of this type of terminal and improving the level of production automation.

[0033] In this embodiment, the part of the connecting sleeve 2 that connects with the buckle part 1 is provided with several barbs 21. The barbs 21 are directly engaged in the corresponding groove of the buckle part 1, and then the two are ultrasonically welded together, which further enhances the stability and firmness between the connecting sleeve 2 and the buckle part 1 and extends their service life.

[0034] In this embodiment, the outer surface of the connecting sleeve 2 is provided with elastic hooks 22. The elastic hooks 22 are mainly used for components that are adapted to the terminal, i.e., external components of the terminal, such as the outer shell, to ensure the stability and firmness between the terminal and the external component. The elastic hooks 22 make it easier to install and disassemble the external component. The process is simple and convenient to use.

[0035] Of course, the inner walls on both sides of the end of the latching part 1 are plated with silver. The silver plating makes the latching part 1 easy to polish, with strong reflective ability and good thermal conductivity, electrical conductivity and welding performance. After silver plating, it has strong corrosion resistance, which ensures the service life of the latching part 1. During the use of the terminal, it can improve the quality and reliability of signal transmission.

[0036] In addition, the connecting sleeve 2 is made of steel. Due to its high strength, good toughness, corrosion resistance and durability, steel can withstand great pressure and tension and is not prone to cracking, thus ensuring the service life of the connecting sleeve 2. Moreover, steel is low in cost and easy to process.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
