Description

Technical Field

[0001] This utility model relates to the field of current-carrying terminal technology, and in particular to a high-power copper tube slotted terminal for new energy vehicles. Background Technology

[0002] A DC charging socket is an on-board charging interface used in new energy vehicles to directly charge the vehicle battery via DC. With the increasing growth of the new energy vehicle market, people have higher and higher requirements for charging speed. Traditional DC charging port terminals for new energy vehicles can no longer meet the current carrying capacity and temperature rise requirements of high-power fast charging. Moreover, the manufacturing process of traditional DC terminals is complex, cannot be automated, and is expensive, making it difficult to meet customer needs. Summary of the Invention

[0003] This application provides a high-power copper tube slotted terminal for new energy vehicles. The terminal is designed and manufactured with full consideration of the needs of automated production. For example, the slotting process of the elastic arm, the installation position of the clamp, and the design of the sealing ring groove are all convenient for the operation of automated equipment. This greatly reduces the reliance on manual operation and reduces labor costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-power copper tube slotted terminal for new energy vehicles, comprising:

[0005] The terminal body includes a clamping section, a fixing section and a connecting section integrally arranged in sequence along the axial direction. A number of elastic arms formed by the grooving device evenly splitting the clamping section are arranged around one side of the clamping section in the circumferential direction. The free ends of the elastic arms are bent outward to form a flared mouth.

[0006] A clamp is provided at the flared end of the terminal and is used to engage the terminal with a sleeve that is fitted onto the outer wall of the terminal. The elastic arm is recessed inward along the circumference on the side away from the fixed section to accommodate the clamp.

[0007] A sealing ring is located in the middle of the terminal and is used for sealing connection between the terminal and the sleeve. The fixed section is recessed near the connecting section and has a sealing ring groove for accommodating the rubber sealing ring.

[0008] As an improvement, a stress relief groove is provided at the connection between the elastic arm and the fixed section, with a circumferentially recessed groove.

[0009] As an improvement, the fixed section has several drainage holes arranged circumferentially between the stress relief groove and the sealing ring groove.

[0010] As an improvement, the terminal body is sequentially provided with a nickel plating layer and a silver plating layer.

[0011] As an improvement, the terminal also includes a sealing plug. The terminal body has a cavity inside, and the sealing plug is set inside the cavity with a flared opening, so that the outer wall of the sealing plug abuts against the inner wall of the cavity.

[0012] As an improvement, the flexible arm is tilted inward by a closing device.

[0013] As an improvement, the connecting section is flattened into a plate-like structure using a flattening device.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) The terminal adopts a clamping section, fixing section and connecting section integrated along the axial direction. This integrated structure greatly reduces the assembly steps in the production process and avoids the assembly error caused by the combination of multiple parts, thereby simplifying the entire production process. At the same time, the elastic arm is formed by the grooving equipment. This process not only ensures the uniformity and consistency of the elastic arm, but also further reduces the manual operation steps, making the production more efficient.

[0016] (2) Since the terminal is designed and manufactured with full consideration of the needs of automated production, such as the slotting process of the elastic arm, the installation position of the clamp, the design of the sealing ring groove, the flattening process of the connecting section, and the inward tilting of the elastic arm through the closing equipment, all of these facilitate the operation of automated equipment. This greatly reduces the dependence on manual operation and reduces labor costs. In addition, the integrated structural design also reduces the extra time caused by component assembly, further reducing production costs.

[0017] (3) The design of this terminal fully considers the compatibility of automated equipment. For example, the free end of the elastic arm is bent outward to form a flared mouth. This structure not only facilitates the snapping with the sleeve, but also facilitates the gripping and positioning of automated equipment. At the same time, the design of the clamp groove and sealing ring groove also fully considers the installation requirements of automated equipment, so that the entire production process can be carried out more smoothly.

[0018] (4) Because the terminal is designed and manufactured with full consideration of automation and standardization, the entire production process can be carried out more efficiently. This not only improves production efficiency but also reduces production costs, providing a strong guarantee for large-scale mass production. In addition, the integrated structural design and uniform grooving process also ensure the consistency and reliability of the product, providing stable quality assurance for large-scale production;

[0019] (5) The stress relief groove reduces the risk of terminal damage caused by stress concentration and improves the durability of the product;

[0020] (6) The drainage holes effectively prevent moisture accumulation and improve the moisture-proof performance of the terminals;

[0021] (7) The addition of nickel and silver plating improves the conductivity and corrosion resistance of the terminals;

[0022] (8) The sealing plug enhances the sealing performance of the terminal and prevents the internal cavity from being disturbed by the external environment. Attached Figure Description
