Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

These terms are used to distinguish one component from another. Therefore, the first component discussed below may be referred to as the second component without departing from the teachings of the concept of the present application.

[0026] Those skilled in the art can understand that the accompanying drawings are only schematic diagrams of exemplary embodiments and may not be to scale. The modules or processes in the accompanying drawings are not necessarily essential for implementing the present application and thus cannot be used to limit the protection scope of the present application.

[0027] Currently, the manufacturing method of the terminals in new energy vehicle charging seats mainly adopts machining processes. One common design is to set a plurality of elastic pieces around the tail of the terminal, and the terminal is clamped on the PCB (Printed Circuit Board) through these elastic pieces to achieve electrical contact. However, this design has some problems. First, since the elastic pieces and the terminal are of an integral structure, a plurality of elastic pieces need to be machined on the terminal during the manufacturing process. This involves complex processing techniques and operations, increasing the manufacturing cost and construction period. The shape and size of each elastic piece need to be precisely controlled to ensure that they can closely cooperate with the PCB and provide reliable electrical contact. Second, due to the presence of a plurality of elastic pieces on the terminal, the overall structure becomes complex. The complex structure leads to mutual interference or damage between the elastic pieces, reducing the reliability and durability of the entire terminal assembly. In addition, the complex processing techniques and structure also result in relatively high manufacturing costs. A large amount of manpower and resources are invested during the processing, and at the same time, manufacturing complex terminal assemblies also increases the material and equipment costs. These factors increase the manufacturing cost of new energy vehicle charging seats accordingly.

[0028] In view of this, the embodiments of the present application provide a terminal assembly, as Figures 1 to 5 shown, by setting the elastic piece structure 300 as an independent structure to solve at least part of the above technical problems.

[0029] Please refer to Figure 1 , Figure 1Schematically shows the overall structure of a terminal assembly provided by an embodiment of the present application. The terminal assembly includes a circuit board 200, a plurality of elastic sheet structures 300, and terminals 100. The circuit board 200 has a first mounting hole 210. The plurality of elastic sheet structures 300 surround the first mounting hole 210 and are connected to the circuit board 200. The terminal 100 passes through the first mounting hole 210, and the terminal 100 includes a first circumferential portion 110. The plurality of elastic sheet structures 300 connect the first circumferential portion 110 to the circuit board 200, so that the terminal 100 is connected to the circuit board 200. By setting the elastic sheet structure 300 as an independent structure, the processing technology of the elastic sheet structure 300 as an independent structure is simple, the terminal assembly is simplified and the processing technology is simple. The elastic sheet structure 300 is connected to the circuit board 200 to realize the connection between the terminal 100 and the circuit board 200, and meet the basic requirement that the terminal 100 needs to be connected to the circuit board 200.

[0030] It can be understood that the first mounting hole 210 is a terminal mounting hole. The plurality of elastic sheet structures 300 means that the number of elastic sheet structures 300 is set to be at least greater than or equal to 2. When the number of elastic sheet structures 300 is 2, the two elastic sheet structures 300 are arranged oppositely; when the number of elastic sheet structures is 3, the three elastic sheet structures 300 are arranged equidistantly around the first mounting hole 210; when the number of elastic sheet structures 300 is 4, the four elastic sheet structures 300 are arranged equidistantly around the first mounting hole 210. The greater the number of elastic sheet structures 300, the greater the connection strength between the terminal 100 and the circuit board 200. The elastic sheet structure 300 is designed to provide necessary support and connection functions to ensure that the terminal 100 can firmly pass through the first mounting hole 210. The number of elastic sheet structures 300 is specifically designed adaptively according to the actual use situation.

[0031] In some embodiments, the circuit board 200 may be a PCB (Printed Circuit Board). The circuits on the PCB can be densely wired, and high-density wiring can be achieved through a multi-layer stacking method. This wiring method can save space, make the electronic device more compact, and meet the requirements of modern electronic products for miniaturization and light weight.

[0032] In some embodiments, the minimum diameter of the circle surrounded by the plurality of elastic sheet structures 300 is smaller than the outer diameter of the first circumferential portion 110.

[0033] It can be understood that the minimum diameter of the circle surrounded by the plurality of elastic sheet structures 300 refers to the diameter of the circle surrounded by the plurality of elastic sheet structures 300 when the plurality of elastic sheet structures 300 are not in contact with the first circumferential portion 110. That is, when the plurality of elastic sheet structures 300 are not stressed, the diameter of the circle surrounded by the plurality of elastic sheet structures 300. The minimum diameter of the circle surrounded by the plurality of elastic sheet structures 300 is smaller than the outer diameter of the first circumferential portion 110. When the terminal 100 penetrates the first mounting hole 210, the plurality of elastic sheet structures 300 will deform. The deformation is caused by the flexibility and elastic characteristics of the elastic sheet structures 300. The deformed plurality of elastic sheet structures 300 apply a force to the first circumferential portion 110 towards the inside of the first circumferential portion 110, so that the relative position between the plurality of elastic sheet structures 300 and the first circumferential portion 110 is limited, and thus the relative position between the terminal 100 and the circuit board 200 is limited. In other words, the plurality of elastic sheet structures 300 are forced to closely adhere to the first circumferential portion 110 to ensure the relative position between the terminal 100 and the circuit board 200 remains stable. To meet this requirement, it is necessary to ensure that the minimum diameter of the circle surrounded by the plurality of elastic sheet structures 300 is smaller than the outer diameter of the first circumferential portion 110, and make appropriate designs and adjustments according to the deformation effect. In this way, the relative position between the terminal 100 and the circuit board 200 can be reliably limited, ensuring the stability of the connection and good electrical contact.

[0034] In some embodiments, the circuit board 200 includes opposite first and second board surfaces 220 and 230. Please refer to Figure 2 , Figure 2 , which schematically shows the overall structure of the elastic sheet structure provided by the embodiment of the present application. The elastic sheet structure 300 includes an extension component 310 and a contact portion 320. The extension component 310 extends from the first board surface 220 into the first mounting hole 210; the contact portion 320 is connected to the extension component 310, and the contact portion 320 is located in the first mounting hole 210. When the terminal 100 penetrates the first mounting hole 210, the contact portion 320 abuts against the first circumferential portion 110.

[0035] Specifically, the circuit board 200 is a planar board-like component having two different board surfaces, namely a first board surface 220 and a second board surface 230. The circuit board 200 can be used to mount electronic components and make circuit connections. The extension assembly 310 extends from the first board surface 220 into the first mounting hole 210. That is, the extension assembly 310 itself may or may not be connected to the first board surface 220, and the extension assembly 310 is for extending into the first mounting hole 210. When the terminal 100 passes through the first mounting hole 210, the contact portion 320 connected to the extension assembly 310 can abut against the first circumferential portion 110. The elastic piece structure 300 is made to abut against the first circumferential portion 110. This abutting manner ensures a tight contact between the elastic piece structure 300 and the first circumferential portion 110, thereby achieving the limitation of the relative position between the terminal 100 and the circuit board 200. Through the design of the extension assembly 310 and the contact portion 320, the stability and reliability of the connection can be ensured, and at the same time, the necessary support and positioning functions are provided.

[0036] In some embodiments, refer to Figure 2 , Figure 2 which schematically shows the overall structure of the elastic piece structure provided by the embodiment of the present application. The extension assembly 310 includes a first extension portion 311, a second extension portion 312 and a first transition portion 313. The first extension portion 311 is provided on the side of the first board surface 220 facing away from the second board surface 230. The second extension portion 312 is provided on the side of the first extension portion 311 close to the first mounting hole 210. One end of the first transition portion 313 is connected to the first extension portion 311, and the other end is connected to the second extension portion 312.

[0037] It can be understood that the side of the second extension portion 312 away from the first transition portion 313 is connected to the contact portion 320. Specifically, the first extension portion 311, the second extension portion 312 and the first transition portion 313 may be plate-like structures. The first extension portion 311 is provided on the side of the first board surface 220 facing away from the second board surface 230 and partially extends into the first mounting hole 210. The first transition portion 313 is connected to the first extension portion 311, and the first transition portion 313 is inclined, and the inclination direction intersects the plane where the first board surface 220 is located. The second extension portion 312 is connected to the first transition portion 313, and the second extension portion 312 extends into the first mounting hole 210. The inclined setting of the first transition portion 313 can achieve the bending of the extension assembly 310, so that the extension assembly 310 can better cooperate with the contact portion 320 to achieve the connection between the terminal 100 and the circuit board 200.

[0038] In some embodiments, the circuit board 200 has a second mounting hole 240. The shrapnel structure 300 further includes shrapnel welding feet 330. The shrapnel welding feet 330 are connected to the extension assembly 310, and the shrapnel welding feet 330 are provided on a side of the extension assembly 310 away from the contact portion 320. Among them, the shrapnel welding feet 330 are provided in the second mounting hole 240 so that the shrapnel structure 300 is connected to the circuit board 200.

[0039] It can be understood that the second mounting hole 240 is used to mount the shrapnel welding feet 330. In this embodiment, through the cooperation of the shrapnel welding feet 330 and the second mounting hole 240, the connection between the shrapnel structure 300 and the circuit board 200 is realized. The number of the shrapnel welding feet 330 provided is the same as the number of the second mounting holes 240 provided.

[0040] In some embodiments, at least one shrapnel welding foot 330 can be provided on one shrapnel structure 300. When one shrapnel welding foot 330 is provided on one shrapnel structure 300, the shrapnel welding foot 330 is provided on a side of the extension assembly 310 away from the contact portion 320. A second mounting hole 240 is formed at a corresponding position on the circuit board 200. Through the connection between the shrapnel welding foot 330 and the second mounting hole 240, the connection between the shrapnel structure 300 and the circuit board 200 is realized.

[0041] When two shrapnel welding feet 330 are provided on one shrapnel structure 300, the two shrapnel welding feet 330 can be provided on a side of the extension assembly 310 away from the contact portion 320. At the same time, a second mounting hole 240 is formed at a corresponding position on the circuit board 200. Through the connection between the shrapnel welding feet 330 and the second mounting hole 240, the connection between the shrapnel structure 300 and the circuit board 200 is realized. By providing two shrapnel welding feet 330 on a side of the extension assembly 310 away from the contact portion 320, compared with providing one shrapnel welding foot 330, the connection strength between the shrapnel structure 300 and the circuit board 200 is better. In addition, the two shrapnel welding feet 330 can also be provided on both sides in the extending direction of the extension assembly 310, which can achieve better stability while realizing the connection between the shrapnel structure 300 and the circuit board 200. In the design, according to the specific usage situation, the number of the shrapnel welding feet 330 and the second mounting holes 240 can be determined according to the requirements of the circuit board 200 and the size of the first mounting hole 210. This depends on the actual application requirements and connection requirements. Through adaptive design, the number and position of the shrapnel welding feet 330 and the second mounting holes 240 can be adjusted according to the specific situation to achieve the best connection effect.

[0042] In some embodiments, the connection between the shrapnel solder leg 330 and the second mounting hole 240 is such that the shrapnel solder leg 330 is inserted into the second mounting hole 240 and can be soldered to the circuit board 200 through wave soldering or reflow soldering processes. The shrapnel solder leg 330 penetrates the entire circuit board 200, which can provide sufficient strength for the extension component 310 and ensure the contact stability of the shrapnel structure 300 in its working state.

[0043] In some embodiments, the shrapnel structure 300 further includes a strengthening portion 340. The strengthening portion 340 is connected to the extension component 310 and is disposed on the side of the extension component 310 away from the second board surface 230.

[0044] Specifically, the strengthening portion 340 is intended to enhance the strength and stability of the extension component 310 and prevent damage to the first extension portion 311 due to bending resulting in structural fracture. When the terminal 100 penetrates the first mounting hole 210, the shrapnel structure 300 will deform, that is, the extension component 310 will bend. Therefore, by providing the strengthening portion 340 on the extension component 310, additional support and stiffness can be provided, enabling the shrapnel structure 300 to withstand the deformation force of the terminal 100, and the strengthening portion 340 disperses the stress to the entire structural part of the extension component 310, thereby reducing the pressure and damage risk at a single point. The setting of the strengthening portion 340 helps to ensure the stability and reliability of the shrapnel structure 300, thus meeting the structural requirements for the connection between the terminal 100 and the circuit board 200.

[0045] In some embodiments, the strengthening portion 340 can be set in a bulge shape or a protrusion. As long as it can help to ensure the stability and reliability of the shrapnel structure 300 and thus meet the structural requirements for the connection between the terminal 100 and the circuit board 200, the actual shape is not specifically limited.

[0046] In some embodiments, the first circumferential portion 110 has opposite first and second end faces, and a first support portion 120 and a second support portion 130 are respectively corresponding to the first and second end faces. The terminal 100 further includes a seal 160, and the seal 160 is respectively connected to the first support portion 120 and the second support portion 130.

[0047] Specifically, since the connection between the circuit board 200 and the terminal 100 needs to be sealed, the first support portion 120 and the second support portion 130 are provided for better sealing effect, and seals 160 are provided on both the first support portion 120 and the second support portion 130. This can ensure that the connection between the circuit board 200 and the terminal 100 is effectively sealed to prevent impurities from entering.

[0048] In some embodiments, the difference between the outer diameter of the first circumferential portion 110 and the outer diameter of the first support portion 120 is greater than 3.5 mm. That is, the outer diameter of the first circumferential portion 110 is greater than the outer diameter of the first support portion 120 by 3.5 mm.

[0049] It can be understood that the outer diameter of the second support portion 130 may be the same as the outer diameter of the first support portion 120, that is, the difference between the outer diameter of the first circumferential portion 110 and the outer diameter of the second support portion 130 is greater than 3.5 mm, and the outer diameter of the first circumferential portion 110 is greater than the outer diameter of the second support portion 130 by 3.5 mm; or, the outer diameter of the second support portion 130 is greater than the outer diameter of the first circumferential portion 110.

[0050] In view of this, the outer diameter of the first circumferential portion 110 is greater than that of the first support portion 120. After the seal 160 is installed on the first support portion 120, when the terminal 100 penetrates the first mounting hole 210, the seal 160 on the first support portion 120 will contact the elastic sheet structure 300, which may hinder the installation of the terminal 100.

[0051] A second transition portion 180 is provided between the first circumferential portion 110 and the first support portion 120, and the first circumferential portion 110 and the first support portion 120 are connected together through the second transition portion 180; a second transition portion 180 is provided between the first circumferential portion 110 and the second support portion 130, and the first circumferential portion 110 and the second support portion 130 are connected together through the second transition portion 180. The shape of the second transition portion 180 may be arc-shaped or a sloping plate, etc. No specific limitation is imposed on the shape of the second transition portion 180 as long as it can realize the connection between the first circumferential portion 110 and the first support portion 120 and the connection between the first circumferential portion 110 and the second support portion 130.

[0052] In some embodiments, both the first support portion 120 and the second support portion 130 are annular. Regarding the thicknesses of the first support portion 120 and the second support portion 130, the thickness range of the first support portion 120 is 0.8 mm to 1.5 mm, and the thickness range of the second support portion 130 is 0.8 mm to 1.5 mm.

[0053] Regarding the inner and outer diameters of the first support portion 120 and the inner and outer diameters of the second support portion 130, the following situations exist:

[0054] Situation 1: The outer diameter of the first support portion 120 is the same as the outer diameter of the second support portion 130, and no specific limitation is imposed on the inner diameter of the first support portion 120 and the inner diameter of the second support portion 130, which may be the same or different;

[0055] Case 2: The outer diameter of the first support portion 120 is different from the outer diameter of the second support portion 130; the difference between the outer diameter of the first support portion 120 and the outer diameter of the second support portion 130 is 0.1 - 0.7 mm, that is, the outer diameter of the first support portion 120 is 0.1 - 0.7 mm larger than the outer diameter of the second support portion 130 or the outer diameter of the second support portion 130 is 0.1 - 0.7 mm larger than the outer diameter of the first support portion 120; the inner diameter of the first support portion 120 and the inner diameter of the second support portion 130 are not specifically limited and can be the same or different.

[0056] In some embodiments, an O-ring or gasket etc. can be selected to be used as the seal 160. These seals 160 are provided outside the first support portion 120 and outside the second support portion 130. Through their elastic compression effect, a sealed environment is formed at the connection between the circuit board 200 and the terminal 100. Both O-rings and gaskets have good sealing performance and can adapt to different joint surface shapes and pressure requirements. A sealing method filled with liquid silicone can also be adopted at the first support portion 120 and the second support portion 130. Liquid silicone has good sealing performance and elasticity and can tightly fill and coat the first support portion 120 and the second support portion 130 to form a reliable sealing layer. This method can provide more comprehensive sealing protection at the connection between the circuit board 200 and the terminal 100. Whether using an O-ring, a gasket or liquid silicone, the design and selection of the seal 160 should consider the nature of the medium, the shape of the connection part and the requirements of the application environment. By using a suitable seal 160, reliable sealing at the connection between the circuit board 200 and the terminal 100 can be ensured, and the reliability and performance of the system can be improved.

[0057] In some embodiments, please refer to Figure 3 , Figure 3 which schematically shows the overall structure of the terminal provided by the embodiment of the present application. The terminal 100 further includes a plug-in end 140 and a connection end 170. The plug-in end 140 is connected to the first support portion 120, and the plug-in end 140 is provided on the side of the first support portion 120 away from the first circumferential portion 110. The connection end 170 is connected to the second support portion 130, and the connection end 170 is provided on the side of the second support portion 130 away from the first circumferential portion 110. Specifically, the plug-in end 140 is used for plugging into a charging socket; the connection end 170 has a connection hole 171, and the terminal 100 is connected to the charging socket by installing a bolt at the connection hole 171.

[0058] In some embodiments, the terminal 100 has a groove 150, and the opening of the groove 150 penetrates through a partial circumference of the first support portion 120 or the second support portion 130.

[0059] It can be understood that the groove 150 can be provided on the outer peripheral surface of the first support portion 120, can be provided on the outer peripheral surface of the second support portion 130, can be provided on the inner peripheral surface of the first support portion 120, or can be provided on the inner peripheral surface of the second support portion 130. The groove 150 can be provided on a partial outer peripheral surface of the first support portion 120, and / or the entire outer peripheral surface of the first support portion 120, can be provided on a partial inner peripheral surface of the second support portion 130, and / or the entire inner peripheral surface of the second support portion 130. When the seal 160 is made of liquid silicone, in order to improve the connection strength between the seal 160 and the first support portion 120 and the connection strength between the seal 160 and the second support portion 130, the design of the groove 150 increases the contact area between the seal 160 and the first support portion 120 and the second support portion 130, thereby increasing the connection strength. The shape of the groove 150 is not limited to being circular, triangular, diamond-shaped, rectangular, etc. Whether the shape of the groove 150 is circular, triangular, diamond-shaped, rectangular or other shapes, it helps to enhance the connection between the seal 160 and the support portion. The specific distribution position of the groove 150 is adaptively arranged according to the actual use situation.

[0060] In some embodiments, the first support portion 120, the second support portion 130, the first circumferential portion 110, the insertion end 140, and the connection end 170 are integrally formed structures. In this embodiment, a stamping and curling method can be used to form a closed circumference on the terminal 100. The circumference specifically includes the first circumferential portion 110, the first support portion 120, and the second support portion 130. The connection between the terminal 100 and the circuit board 200 is achieved through the cooperation of the first circumferential portion 110 and the elastic piece structure 300. The first support portion 120 and the second support portion 130 provide an installation position for the seal 160 and seal the connection between the terminal 100 and the circuit board 200. The design of this integrally formed structure can increase the structural stability and sealing performance of the terminal 100. Through the stamping and curling processing method, an efficient manufacturing and assembly process can be achieved. At the same time, the integrated design reduces the number of components and improves the reliability and durability of the terminal 100.
