Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging, in particular to a new energy vehicle charging socket stamping terminal. Background Art

[0002] AC charging sockets are standard equipment in the new energy vehicle sector. Their core components, the LNPE (L-line, N-line, PE-line) charging terminals, were previously manufactured using machining processes, resulting in relatively high costs. To reduce costs, current NEV charging socket suppliers are actively developing stamped terminals as an alternative.

[0003] However, stamped terminals face two major technical challenges during their application: one is the high cost of encapsulation, which includes many pre-processing steps, long molding time, and the need to remove burrs after molding; the other is the need to add secondary locking structures and anti-retraction structures to prevent the terminals from retreating during use, which not only increases the length of the terminals but also further increases the cost.

[0004] Therefore, the market urgently needs a new energy vehicle charging socket stamping terminal solution that can reduce the cost of encapsulation and minimize the terminal length. Utility Model Content

[0005] The utility model aims to solve the technical problems existing in the prior art and provides a new energy vehicle charging socket stamping terminal to solve the problems of cumbersome rubber coating and complicated assembly process of the stamping terminal.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: a new energy vehicle charging socket stamping terminal, including a terminal base, a spring and a sealing ring; the terminal base includes a charging socket reserved in the front section, a cable crimping groove reserved in the rear section, and a sealing frame located between the charging socket and the cable crimping groove; the spring is assembled in the charging socket, and the sealing ring is injection molded onto the sealing frame.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the spring is formed by stamping and rolling a strip, and a gap is reserved after rolling; the inner diameter of the spring narrows from both ends to the middle.

[0009] Furthermore, a catch is formed on the outside of the terminal base to prevent the terminal from retreating.

[0010] Furthermore, a front convex point and a rear convex point for limiting the front and rear end surfaces of the spring are formed in the charging socket of the terminal base.

[0011] Furthermore, the front convex point is provided with a guiding slope along the charging plug insertion direction.

[0012] Furthermore, the terminal base is formed by stamping and winding a strip material.

[0013] Furthermore, the front section of the terminal base is reserved with a lock buckle and a dovetail buckle for winding and fixing.

[0014] Furthermore, the rear section of the terminal base is provided with cable crimping wings extending along both sides of the cable crimping groove.

[0015] Furthermore, a plurality of anti-slip protrusions are provided in the cable crimping groove.

[0016] Furthermore, the terminal base is provided with a through hole located on the sealing frame and a drainage hole located on the front side of the sealing frame.

[0017] Furthermore, the new energy vehicle charging socket stamping terminal provided by the present invention has at least the following beneficial effects compared with the prior art:

[0018] 1. Reduction of material costs: By changing the laminating material from high-cost silicone rubber to more economical new materials, the material cost expenditure is directly reduced.

[0019] 2. Process simplification: It eliminates the complex pre-treatment steps before traditional terminal encapsulation, such as sandblasting to remove the plating and applying adhesive, which not only saves time and process costs, but also improves production consistency and efficiency.

[0020] 3. Omission of post-processing process: It solves the problems of glue overflow and flash that are easy to occur after laminating. No additional flash removal process is required, which reduces labor costs and improves production efficiency.

[0021] 4. Improved production efficiency: The lagging time is significantly shortened, from an average of one per 2 minutes to a faster speed, which greatly improves the overall production capacity of the production line.

[0022] 5. Design optimization: Through innovative design, the number of waterproof ribs is reduced, the length of the encapsulated area and the terminal itself is shortened, the amount of terminal and encapsulated materials used is reduced, and costs are further reduced.

[0023] 6. Process optimization: In order to ensure the bonding strength between the sealing ring and the terminal, the existing stamped terminal is wrapped with silicone and the terminal needs to be pre-processed. The plating layer is removed by sandblasting and adhesive is applied. The process is complicated, time-consuming and inconsistent. This stamped terminal is used to save the pre-processing step.

[0024] 7. Performance Improvement: Integrated design and manufacturing simplify the assembly process and improve production efficiency. The spring is produced by stamping and rolling strips, which reduces production costs. The spring is replaceable, which greatly reduces the cost of terminal after-sales maintenance and extends the service life of the terminal base. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0032] like Figure 1-Figure 3 As shown, the stamped terminal of the new energy vehicle charging socket of the present utility model includes a terminal base 1, a spring 2 and a sealing ring 3; the terminal base 1 includes a charging socket 1.1 reserved at the front section, a cable crimping groove 1.2 reserved at the rear section, and a sealing frame 1.3 located between the charging socket 1.1 and the cable crimping groove 1.2; the spring 2 is assembled in the charging socket 1.1, and the sealing ring 3 is injection molded onto the sealing frame 1.3.

[0033] As an embodiment, the reed 2 is stamped and rolled from a strip, and a notch is reserved after rolling; the inner diameter of the reed 2 narrows from both ends to the middle. The reed is stamped and rolled from a strip, and this process not only reduces production costs but also improves production efficiency. A notch is reserved in the rolled reed. This design allows the reed to have a certain elastic deformation ability during installation and use, so that it can better adapt to the insertion and removal of the charging plug and ensure good conductive contact. The inner diameter of the reed narrows from both ends to the middle. This design enhances the contact pressure between the reed and the charging plug, and improves the reliability and stability of the contact.

[0034] Specifically, a catch 4 is formed on the outside of the terminal base 1 to prevent the terminal from retreating.

[0035] This prevents the terminals from loosening or retreating due to vibration or external force during use, thereby ensuring the safety and reliability of the charging connection.

[0036] As an embodiment, the charging socket 1.1 of the terminal body 1 is formed with front bumps 1.4 and rear bumps 1.5 for limiting the front and rear end surfaces of the reed 2. This precisely positions the reed within the charging socket. When the reed is assembled into the charging socket, the front and rear bumps respectively contact the front and rear end surfaces of the reed, thereby limiting the reed's range of movement within the socket and ensuring stable contact between the reed and the charging plug.

[0037] Specifically, the front convex point 1.4 is provided with a guiding slope along the charging plug insertion direction.

[0038] As an embodiment, the terminal base 1 is formed by stamping and winding a strip of material. The front end of the terminal base 1 is provided with a lock 1.6 and a dovetail buckle 1.7 for winding and securing. This manufacturing process not only reduces production costs but also improves production efficiency, resulting in a terminal base with high strength and rigidity.

[0039] As an embodiment, the rear section of the terminal base 1 is reserved with cable crimping wings 1.8 extending along both sides of the cable crimping groove 1.2, and a plurality of anti-slip protrusions are provided in the cable crimping groove 1.2. The cable and the terminal base are firmly connected together by mechanical pressure. The design of the cable crimping wings not only improves the stability of the cable connection, but also prevents the cable from loosening or falling off due to vibration or external force during long-term use. When the cable is crimped in the crimping groove, the anti-slip protrusions can tightly bite the surface of the cable to prevent the cable from sliding or shifting during the crimping process.

[0040] As an embodiment, the terminal base 1 is further provided with a through hole 1.9 located on the sealing frame 1.3 and a drainage hole 1.10 located on the front side of the sealing frame 1.3.

[0041] When the sealing ring is injection molded onto the sealing frame 1.3, the through-holes serve as channels for the flow of the rubber compound. The rubber compound fills the through-holes during the injection molding process and forms a strong connection after curing, thereby firmly fixing the sealing ring to the sealing frame.

[0042] When the terminal encounters water or a humid environment, it can drain the accumulated water or moisture in time to prevent moisture from invading the terminal and causing a short circuit or damage.

[0043] The working principle of this utility model is as follows:

[0044] The terminal is mainly composed of three parts: terminal base 1, spring 2 and sealing ring 3.

[0045] Terminal body 1: As the main structure of the terminal, the terminal body integrates the charging jack 1.1 for connecting the charging plug, the cable crimping groove 1.2 for securing and connecting the cable, and the sealing frame 1.3, which provides the installation base for the sealing ring. This integrated design not only simplifies the assembly process but also enhances the integrity and stability of the terminal.

[0046] Reed 2: The reed is installed in the charging socket and provides electrical conductivity and contact. Its elastic deformation ensures good contact between the charging plug and the terminal, thus transmitting electrical energy. The reed's design also takes into account manufacturing costs and ease of assembly. It is manufactured through a stamping process, reducing production costs.

[0047] Sealing Ring 3: The sealing ring is fixed to the sealing frame through injection molding technology, achieving the terminal's sealing function. This design effectively prevents external factors such as moisture and dust from invading the charging jack and cable crimping area, ensuring the reliability and safety of the terminal. Furthermore, the injection-molded sealing ring has excellent elasticity and durability, ensuring long-term sealing.

[0048] It should be noted that, in this article, the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise expressly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0049] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0050] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
