Description

Technical Field

[0001] This application relates to the field of socket technology, and more particularly to a high-power socket pin and socket. Background Technology

[0002] High-power sockets are crucial interfaces for charging devices and electrical appliances, and the power density of these devices is constantly increasing. Consequently, the power requirements for sockets are also rising. The female socket pins are a vital component of the socket, used to connect with the male plug pins, establishing the electrical connection between them.

[0003] Female socket pins typically use contact springs to clamp and secure the male pins, ensuring a stable electrical connection. However, modern female socket pins often use two contact springs (one upper and one lower). This design results in lower current output, unstable contact between the contact springs and the male pins, and a tendency to overheat during operation. It also fails to improve the power density of the socket.

[0004] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a high-power socket pin and socket, which aims to achieve high current output, reduce heat generation during operation, and improve the stability of pin contact.

[0006] The technical solution adopted by this application to solve the technical problem is as follows:

[0007] The first aspect provides a high-power socket pin, including:

[0008] Wiring segment; the wiring segment is used to connect the socket wiring harness.

[0009] And a snap-fit ​​section, which is connected to one end of the connector section. The snap-fit ​​section is used to snap the male pin of the plug. The snap-fit ​​section includes several concave contact springs, which are arranged concavely around the central axis of the snap-fit ​​section.

[0010] Among them, a number of concave contact springs are provided with a reinforcing sleeve at one end away from the wiring section. The reinforcing sleeve is arranged around the central axis of the snap-fit ​​section, and the ends of the number of concave contact springs are connected to each other through the reinforcing sleeve.

[0011] In one possible implementation, the snap-fit ​​segment includes at least four concave contact springs, which are uniformly arranged concave around the central axis of the snap-fit ​​segment and arranged opposite each other in pairs.

[0012] In one possible implementation, the wiring segment, the snap-fit ​​segment, and the reinforcing sleeve are integrally molded.

[0015] In one possible implementation, a snap-fit ​​element is provided on the snap-fit ​​segment, which is used to snap onto the mounting base inside the socket body.

[0016] In one possible implementation, the snap-fit ​​connector is positioned on the snap-fit ​​segment near the wiring segment.

[0017] In one possible implementation, the concave contact spring is provided with a gold-plated layer on the side facing the central axis of the snap-fit ​​section.

[0018] The second aspect provides a socket, including: a socket body and a high-power socket pin as described in the first aspect, wherein a mounting base is provided within the socket body and the high-power socket pin is disposed within the mounting base.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "several" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0031] This utility model provides, for example Figure 1 , Figure 2 and Figure 3The high-power socket pin shown is an important component in high-power, high-current sockets. It is used to connect with the male pin of a plug, realizing the electrical connection between the female socket pin and the male pin. The main structure of this high-power socket pin includes: a wiring section 1 and a snap-fit ​​section 2. The wiring section 1 is used to connect the socket wiring harness; the snap-fit ​​section 2 is connected to one end of the wiring section 1 and is used to snap the male pin of the plug. The snap-fit ​​section 2 includes several recessed contact springs 21, which are recessed around the central axis of the snap-fit ​​section 2. A reinforcing sleeve 3 is provided at the end of each recessed contact spring 21 facing away from the wiring section 1. The reinforcing sleeve 3 is arranged around the central axis of the snap-fit ​​section 2, and the ends of the recessed contact springs 21 are interconnected through the reinforcing sleeve 3. By completely covering the front end of the snap-fit ​​section 2 with the reinforcing sleeve 3, the structural strength of the recessed contact springs 21 on the snap-fit ​​section 2 is increased, effectively protecting the snap-fit ​​section 2.

[0032] It should be noted that female socket pins typically use contact springs to clamp and secure the male pins, ensuring a stable electrical connection. However, current female socket pins often use two contact springs (recessed contact springs 21), which results in lower current output, unstable contact between the contact springs (recessed contact springs 21) and the male pins, and a tendency to overheat during operation. This design also fails to improve the power density of the socket.

[0033] This utility model adopts an overall fully enclosed design, with the front end of the locking segment 2 completely covered, which increases the structural strength of the locking segment 2 and effectively protects it. Furthermore, the locking segment 2 uses four or more concave contact springs 21 in all directions to simultaneously engage, enabling high current output from the socket and ensuring stable and reliable contact of the socket pins, effectively reducing heat generation during operation.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the snap-fit ​​section 2 includes at least four concave contact springs 21. These four concave contact springs 21 are evenly arranged concavely around the central axis of the snap-fit ​​section 2, and are arranged in pairs facing each other. The male pins are connected via these pairs of facing concave contact springs 21 in all directions (up, down, left, right). This effectively improves the conductivity of the socket pins, enabling high current output from the socket, ensuring stable and reliable pin contact, and effectively reducing heat generation during operation.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the wiring segment 1, the snap-fit ​​segment 2, and the reinforcing sleeve 3 are integrally formed.

[0036] Furthermore, the wiring segment 1, the snap-fit ​​segment 2, and the reinforcing sleeve 3 are all made of copper.

[0037] Understandably, copper has one of the highest electrical conductivity values ​​among metals. At 20°C, the electrical conductivity of copper is approximately 59.6 × 10⁻⁶. 6 S / m. This means that copper can transmit current with lower resistance, reducing energy loss during transmission.

[0038] Furthermore, copper has good stability and ductility, and can be drawn into fine wires or pressed into thin sheets. This allows the wiring segment 1, the snap-fit ​​segment 2, and the reinforcing sleeve 3 to be easily integrally stamped.

[0039] Furthermore, such as Figure 1 and Figure 2 As shown, limiting side plates 11 are provided on both sides of the wiring segment 1, and the two limiting side plates 11 are integrally formed with the wiring segment 1. In this embodiment, during the production and assembly process, the limiting side plates 11 can prevent dislocation when the wire harness is welded and aligned with the wiring segment 1. Under the blocking action of the limiting side plates 11, the wire harness can be more easily aligned with the wiring segment 1, which facilitates subsequent welding and improves the efficiency of production and assembly.

[0040] Furthermore, such as Figure 1 As shown, a snap-fit ​​element 22 is provided on the snap-fit ​​section 2. The snap-fit ​​element 22 is used to snap onto the mounting base inside the socket body 4. The snap-fit ​​element 22 secures the high-power socket pins of this solution inside the socket body 4, preventing the socket and plug from becoming loose during repeated insertion and removal cycles over a long period of time.

[0041] Furthermore, such as Figure 1 As shown, the snap-fit ​​component 22 is positioned on the snap-fit ​​section 2 near the wiring section 1. The structural strength of the snap-fit ​​section 2 near the wiring section 1 is relatively high. Positioning the snap-fit ​​component 22 on the snap-fit ​​section 2 near the wiring section 1 can provide support points for both the snap-fit ​​component 22 and the wiring section 1, preventing pin deflection due to uneven force distribution between the snap-fit ​​component 22 and the wiring section 1.

[0042] Furthermore, the concave contact spring 21 has a gold-plated layer on the side facing the central axis of the snap-fit ​​section 2. It is understood that gold is an excellent conductive material, and gold plating on the terminal block can significantly improve its conductivity. This helps reduce resistance loss during current transmission, ensuring that current can pass through the terminal block stably and efficiently, thereby improving the overall performance and efficiency of the circuit. Therefore, the gold plating on the terminal block enhances conductivity. In addition, the gold plating on the terminal block also prevents oxidation and improves reliability. This makes the terminal block more durable and reduces the probability of failure due to poor contact or oxidation.

[0043] like Figure 3 and Figure 4As shown, the second aspect of this solution provides a socket, including: a socket body 4 and a high-power socket pin as described in the first aspect. A mounting base is provided within the socket body 4, and the high-power socket pin is disposed within the mounting base. The socket body 4 (outer shell) is typically made of high-temperature resistant and flame-retardant plastic material. With the support of the high-power, highly conductive socket pin, the safety and reliability of the socket during use are guaranteed.

[0044] In summary, this utility model provides a high-power socket pin and socket. The utility model adopts a fully enclosed design, with the front end of the locking section 2 completely covered, increasing the structural strength of the locking section 2 and effectively protecting it. Furthermore, the locking section 2 uses four or more recessed contact springs 21 in all directions for simultaneous contact, enabling high current output, stable and reliable pin contact, and effectively reducing heat generation during operation.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
