Description

Technical Field

[0001] The utility model relates to the technical field of charging, and in particular to a charging terminal assembly and a charging pile. Background Art

[0002] In the market of new energy vehicles, more and more users need to charge new energy vehicles in different scenarios. New energy vehicles usually have their own double-head charging guns, one end of which is connected to the new energy vehicle and the other end is connected to the charging pile. The charging terminal used to connect the charging pile and the gun head of the new energy vehicle is set on the charging pile, so as to facilitate the charging connection between the charging pile and the charging plug of the car, so the charging terminal is an important component for realizing the charging connection.

[0003] In the prior art, the outer shell wraps the internal charging terminal, and then a soft wire is connected and extended from the bottom of the charging terminal to pass through the outer shell, and finally directly connected to the circuit board to achieve conductive communication connection between the charging pile and the gun holder. However, the charging terminal must realize conductive connection between the charging terminal and the circuit board in the charging pile through a conductive lead. The soft wire is large in size and has limited folding curvature. In addition, the mechanical support of the charging terminal must be realized through a supporting structure. Therefore, this structure occupies a huge space, which is not conducive to saving installation space for the charging terminal in the charging pile. Moreover, the soft wire is difficult to install and position. A soft wire requires at least three screws to fix. Moreover, since it is a soft wire, the position of the wire is uncertain during installation, which is easy to interfere with other devices. Therefore, it is not conducive to the assembly of the charging terminal and the circuit board, and the assembly efficiency is low. Utility Model Content

[0056] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or at least three of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0057] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or at least three other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0058] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0059] The charging terminal assembly provided in this application can be used in charging piles for charging new energy vehicles. Figure 1 Figure 8 and Fig. 9 As shown, the charging pile includes a charging pile shell 5 with an accommodating space, and a circuit board 3 is also provided in the accommodating space, that is, the circuit board 3 is located in the charging pile shell 5, and the circuit board 3 can be detachably connected to the charging pile shell 5, such as by snapping, etc., or can be fixedly connected, such as by bonding, riveting, etc.; the charging terminal assembly of the present application is also arranged in the accommodating space, and the charging terminal assembly is respectively connected to the circuit board 3 and the charging pile shell 5, so that the charging terminal assembly is fixed in the accommodating space and realizes the function of communication and conduction. The specific connection relationship is described in detail in the following embodiments. When the new energy vehicle needs to be charged, the driver plugs the charging plug of the new energy vehicle into the charging terminal assembly, and the new energy vehicle can be charged through the charging pile.

[0060] The charging terminal assembly provided by the present application is described in detail below. Figure 1 and Figure 8 As shown, the charging terminal assembly includes: a charging terminal 1; a conductive support portion 2 which is a rigid conductor and is disposed between the charging terminal 1 and the circuit board 3, wherein the conductive support portion 2 is used for conductive connection between the charging terminal 1 and the circuit board 3, and for supporting the charging terminal 1.

[0061] The conductive support part 2 is made of a rigid conductive material to provide support for the charging terminal 1; the circuit board 3 is a printed circuit board (PCB board), which can improve the integration of electronic components, make the circuit more compact, reduce the overall volume and weight, and have good electrical and mechanical properties to ensure the stability and reliability of the circuit board 3. The conductive support part 2 can be made of metal, preferably copper, and more preferably red copper, and the grade of red copper can be T1, T2, or T3.

[0062] In this embodiment, the conductive support part 2 is used as a rigid conductor, which can not only realize the conductive connection between the charging terminal 1 and the circuit board 3, but also realize the mechanical support of the charging terminal 1. The volume and length are greatly reduced compared with the soft conductor, thereby reducing the occupied space, which is conducive to saving the installation space of the charging terminal 1 in the charging pile, so as to provide more space for other components, simplify the structure, facilitate the assembly of the charging terminal 1 and the circuit board 3, improve the assembly efficiency, and reduce the cost. The rigid structure forms a rigid buffer force arm, so that the plug-in and pull-out force applied by the user during charging can be buffered, thereby reducing the impact of the plug-in and pull-out force on the circuit board 3, and also reducing the probability of damage to the circuit board 3 due to the plug-in and pull-out force, which plays a role in protecting the circuit board 3. In addition, compared with the flexible structure, the rigid structure omits the components for clamping the flexible structure, thereby simplifying the structure, and the rigid structure is easier to install, making the assembly efficiency higher.

[0063] In a specific application, the conductive support portion 2 and the circuit board 3 may be connected in a variety of ways, which are described in detail below.

[0064] The first connection method between the conductive support part 2 and the circuit board 3 is as follows: Figure 1 and Figure 8 As shown, the circuit board 3 is provided with a connecting terminal 4 , and the conductive support portion 2 is conductively connected to the connecting terminal 4 .

[0065] Among them, the connection terminal 4 can be a bench terminal, such as Figure 3 As shown, it specifically includes a connector 42 and two legs 41 spaced apart on the circuit board 3, and the connector 42 is conductively connected to the two legs 41 respectively. A slot for installing the legs 41 is reserved on the circuit board 3, and the legs 41 are inserted into the slot and fixed in the slot by welding or other means to complete the conductive connection between the bench terminal and the circuit board 3; and the conductive support part 2 is conductively connected to the connector 42, thereby realizing the conductive connection between the conductive support part 2 and the bench terminal. Of course, the connecting terminal 4 can also adopt other types of terminals, which are not strictly limited in this application.

[0066] The connection terminal 4 can be fixed on the circuit board 3 by welding or other connection methods. Of course, other connection methods can also be used, which are not strictly limited in this embodiment.

[0067] In this implementation, the conductive support portion 2 is conductively connected to the circuit board 3 via the connecting terminal 4, thereby improving the strength and electrical stability of the conductive connection between the conductive support portion 2 and the circuit board 3, so as to reduce the risk of disconnection between the conductive support portion 2 and the circuit board 3 caused by the plugging and unplugging force applied to the charging terminal 1 when charging the car.

[0068] Furthermore, in this implementation, different connection methods may be used between the conductive support portion 2 and the connection terminal 4 to achieve the connection between the conductive support portion 2 and the connection terminal 4 .

[0069] In some embodiments, Figure 1 and Figure 8 As shown, the conductive support part 2 and the connecting terminal 4 are detachably conductively connected, which not only improves the assembly efficiency of the conductive support part 2 and the connecting terminal 4, but also facilitates the replacement of the conductive support part 2 or the connecting terminal 4 when the conductive support part 2 or the connecting terminal 4 is damaged, thereby reducing costs.

[0070] In specific applications, such as Figure 1 As shown, the charging terminal assembly further includes a detachable first conductive connector 11 , and the conductive support portion 2 is detachably conductively connected to the connecting terminal 4 via the first conductive connector 11 .

[0071] The first conductive connector 11 may be a detachable connector capable of conducting electricity, such as a detachable connector made of conductive metal, so as to achieve a detachable conductive connection between the conductive support portion 2 and the connecting terminal 4 .

[0072] Specifically, Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10As shown, the first conductive connecting member 11 includes a conductive screw 111, a conductive hole 112 arranged on the conductive support part 2, and a terminal hole 113 arranged on the connecting terminal 4. The conductive hole 112 of the conductive support part 2 and / or the terminal hole 113 on the connecting terminal 4 are screw holes, and a screw hole refers to a through hole with a thread on the inner surface. The conductive screw 111 is threadedly connected with the conductive hole 112 and / or the terminal hole 113, that is, the conductive hole 112 of the conductive support part 2 and the terminal hole 113 on the connecting terminal 4 can both be screw holes, or one of them can be a conductive screw hole, and the other can be a conductive through hole without threads. The conductive screw 111 is threadedly connected to the conductive hole 112 and the terminal hole 113, or is threadedly connected to the conductive hole 112 or the terminal hole 113, and can be tightened. The method of fixing the conductive support part 2 and the connecting terminal 4 by thread connection is simple in structure and saves space. It not only makes the strength and electrical stability of the conductive connection between the conductive support part 2 and the connecting terminal 4 higher, but also reduces the plug-in and pull-out force applied to the charging terminal 1 when charging the car, which causes the risk of disconnection between the charging terminal 1 and the conductive support part 2, thereby increasing the service life of the charging terminal 1. The close contact provides a stable electrical connection, even in the case of heating, which complies with the technical specifications related to the safety of electrical equipment. Moreover, the alignment accuracy requirements of the threaded connection method are not high, and it is also convenient for the disassembly and assembly of the conductive support part 2 and the connecting terminal 4, improving the assembly and maintenance efficiency, and improving the product yield. Moreover, it can be installed by a robotic arm, thereby reducing labor costs and accelerating installation efficiency. In addition, the screw thread connection is a material widely used in the mechanical field, with low procurement costs. Finally, the installation and disassembly of the threaded connection can be completed by a robotic arm, reducing labor costs and accelerating the disassembly and assembly speed.

[0073] In other embodiments, the conductive support portion 2 is conductively connected to the connecting terminal 4 in a fixed manner, that is, the conductive support portion 2 is conductively connected to the connecting terminal 4 in an irremovable manner, such as by welding or riveting, thereby simplifying the structure and reducing the cost.

[0074] Specifically, a non-detachable fixing member is provided between the conductive support portion 2 and the connecting terminal 4, and the conductive support portion 2 and the connecting terminal 4 are fixedly conductively connected through the fixing member, so that the impact of external forces (such as plugging and pulling forces) can be resisted to a certain extent, which not only improves the stability of the connection, but also improves the electrical stability. Among them, the fixing member can be a conductive fixing member, such as a metal rivet, etc., and this application does not strictly limit the fixing member.

[0075] The second connection method between the conductive support part 2 and the circuit board 3: the conductive support part 2 and the circuit board 3 are directly and fixedly conductively connected, that is, the conductive support part 2 and the circuit board 3 are connected without any detachable or non-detachable parts, such as welding, so as to reduce costs.

[0076] The structure of the charging terminal 1 and the connection method with the conductive support part 2 are described in detail below. Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the charging terminal 1 includes a mounting portion 12 and an electrode terminal 13. Figure 4 and Fig. 9 As shown, the electrode terminals 13 are charging electrodes 131 and communication terminals 132. In a specific application, the number of charging electrodes 131 is five, the number of communication terminals 132 is two, and the size of the communication terminals 132 is smaller than that of the charging electrodes 131, so that it is easier to distinguish the charging electrodes 131 and the communication terminals 132, so as to reduce the probability of assembly errors.

[0077] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, the electrode terminal 13 is arranged on the mounting portion 12. The mounting portion 12 is used to fix the electrode terminal 13 so as to integrate the electrode terminals 13 (i.e., the charging electrode 131 and the communication terminal 132) together to form a whole. In addition, the mounting portion 12 also protects the electrode terminal 13, thereby improving the life of the electrode terminal 13.

[0078] like Figure 4 , Figure 5 , Fig. 9 and Fig.11 As shown, the electrode terminal 13 is connected to the conductive support part 2, so that the conductive support part 2 can not only mechanically support the charging terminal 1 formed by the electrode terminal 13 and the mounting part 12, but also realize the conductive connection between the electrode terminal 13 and the conductive support part 2, thereby reducing the occupied space, simplifying the structure, and reducing the cost.

[0079] In a specific application, the charging terminal 1 also includes a conductive fastening structure, and the electrode terminal 13 is conductively connected to the conductive support part 2 through the conductive fastening structure. Therefore, the conductive fastening structure can realize both the mechanical connection between the electrode terminal 13 and the conductive support part 2 and the electrical connection between the electrode terminal 13 and the conductive support part 2, thereby simplifying the structure, improving assembly efficiency, and reducing costs.

[0080] The conductive fastening structure may be implemented in different ways, which are described in detail below.

[0081] In the first implementation, Figure 4 , Figure 5 , Fig. 9 and Fig.11As shown, the conductive fastening structure includes a detachable second conductive connector 14, and the electrode terminal 13 is detachably conductively connected to the conductive support part 2 through the second conductive connector 14, thereby increasing the stability of the connection and communication conductivity between the electrode terminal 13 and the conductive support part 2, facilitating the disassembly and assembly of the electrode terminal 13 and the conductive support part 2, and improving the assembly and maintenance efficiency.

[0082] In some embodiments, Figure 4 , Figure 5 , Figure 6 , Fig. 9 and Fig.11 As shown, the second conductive connector 14 includes a nut 141 , an electrode screw 143 disposed on the electrode terminal 13 , and a through hole 142 disposed on the conductive support portion 2 , and the electrode screw 143 passes through the through hole 142 and is threadedly connected to the nut 141 . Among them, the nut 141 and the electrode screw 143 are both made of conductive materials, such as conductive metal, so that both the mechanical connection between the electrode terminal 13 and the conductive support part 2 and the electrical connection between the electrode terminal 13 and the conductive support part 2 can be achieved, so as to simplify the connection structure and reduce costs; and through the cooperation of the nut 141 and the electrode screw 143, firstly, the mechanical connection can be improved to reduce the risk of disconnection between the charging terminal 1 and the conductive support part 2 due to the plug-in and pull-out force applied to the charging terminal 1 when charging the car, thereby improving the service life of the charging terminal 1; secondly, due to the close contact, it has good electrical connection stability, which complies with technical specifications related to electrical equipment safety; finally, it is also convenient for the conductive support part 2 to be independently set and assembled with the electrode terminal 13 and the connecting terminal 4 without restricting each other, and multiple conductive support parts 2 are independently set and without restricting each other, which improves the assembly and maintenance efficiency of the charging terminal assembly and also improves the yield rate.

[0083] Furthermore, in order to prevent the risk of thread loosening due to the passage of time and temperature changes, anti-loosening nuts can be selected, such as self-tightening nuts used in combination with anti-loosening washers, eccentric nuts composed of convex and concave double nuts, or anti-dropping glue can be used to prevent loosening. The through hole 142 means that the hole penetrates the overall structure itself, and the inner surface of the hole can have threads or other textures for the tightness after installation, or it can have no texture and only a smooth surface.

[0084] In some other embodiments, the second conductive connector 14 includes a conductive nail disposed on the electrode terminal 13 , and the conductive nail is located inside the electrode terminal 13 , and the conductive nail is connected to the conductive support portion 2 .

[0085] The conductive nail can be a conductive screw or other component, and the present application does not strictly limit the type of the conductive nail. The conductive nail is used to connect the electrode terminal 13 with the conductive support part 2, thereby making the structure simpler, easier to implement, and further reducing the cost.

[0086] In the second implementation, the conductive fastening structure includes a non-detachable third conductive connector, and the electrode terminal 13 is fixedly conductively connected to the conductive support part 2 through the third conductive connector, so that it can resist the impact of external forces (such as plug-in and pull-out forces) to a certain extent, which not only improves the stability of the connection, but also improves the electrical stability, thereby increasing the service life of the charging terminal 1.

[0087] Specifically, the third conductive connection member includes a rivet, and the electrode terminal 13 is riveted to the conductive support portion 2 through the rivet. The rivet connection has good load-bearing capacity and shock resistance, thereby improving the reliability of the mechanical connection and electrical connection between the electrode terminal 13 and the conductive support portion 2, and compared with threaded connection and welding, the rivet connection is faster, making the assembly efficiency higher.

[0088] The structure of the mounting portion 12 and its assembly relationship with other components are described in detail below. Figure 1 , Figure 2 , Figure 8 , Fig. 9 As shown, the mounting portion 12 includes an electrode housing 121 and a seat 122 , and the electrode terminal 13 is at least partially located in the electrode housing 121 .

[0089] In a specific application, the electrode housing 121 is an injection molded body formed by an injection molding process, such as Figure 2 and Fig.10 As shown, the injection molded body is provided with channels 1211 for fixing each electrode terminal 13, and each electrode terminal 13 is installed in the corresponding channel 1211 by injection molding, so that each electrode terminal 13 is more stably fixed on the injection molded body and the assembly accuracy is improved.

[0090] Furthermore, the electrode shell part extends out from the wall surface of the charging pile shell, so that the structure can be made more compact, thereby reducing the overall volume of the charging pile and reducing the space occupied by the charging pile.

[0091] Furthermore, if Figure 2 and Fig.12 As shown, the electrode shell 121 is detachably connected to the socket 122 on the circuit board 3, thereby facilitating the disassembly and assembly of the electrode shell 121 and the socket 122, for example, when the electrode terminal needs to be replaced (such as when the electrode terminal is damaged), or when it is necessary to convert the three-phase power supply to a single-phase power supply and remove some of the electrode terminals, thereby improving the assembly and maintenance efficiency, improving the yield rate, and reducing costs.

[0092] In some implementations, such as Fig.12 and Figure 2As shown, a stud 1212 is provided on the electrode shell 121, and a connecting screw hole 1223 is provided on the seat 122, that is, it can be threadedly connected with the connecting screw. In other embodiments, a connecting screw hole 1223 may be provided on the electrode shell 121, and a stud 1212 may be provided on the seat 122, and then the connecting screw is threadedly connected with the connecting screw hole 1223 and the stud 1212 to achieve a detachable connection between the electrode shell 121 and the seat 122. Of course, the electrode shell 121 and the seat 122 can also be connected in other detachable ways such as snap-on, which is not strictly limited in this application.

[0093] In practical applications, the seat 122 may adopt different structures and connection methods, which are described in detail below.

[0094] In the first implementation, Figure 1 and Figure 2 As shown, the seat 122 is detachably connected to the circuit board 3. The detachable connection between the seat 122 and the circuit board 3 can be achieved by snap connection, etc., which is not strictly limited in this application.

[0095] The connection between the seat 122 and the circuit board 3 improves the reliability and stability of the connection between the seat 122 and the circuit board 3, and the detachable nature also facilitates the disassembly and assembly of the seat 122 and the circuit board 3, so as to facilitate the repair or replacement of the seat 122 and the circuit board 3, thereby improving the yield rate and reducing costs.

[0096] In the second implementation, the seat 122 partially passes through the circuit board 3 and abuts against the charging pile housing 5, that is, there is no tight and direct connection between the seat 122 and the circuit board 3, so when the seat 122 is subjected to external force during plugging and unplugging, the force acting on the circuit board 3 is reduced, thereby reducing the probability of the circuit board 3 being damaged by external force. In addition, the seat 122 partially abuts against the charging pile housing 5, and the seat 122 is limited by the abutment force, thereby ensuring the stability of the installation of the seat 122.

[0097] In the above two implementations, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the conductive support portion 2 is passed through the seat 122 and does not need to go around the edge of the seat 122, thereby effectively reducing the length of the conductive support portion 2, thereby reducing the space occupied by the conductive support portion 2, so that the installation space required for the charging terminal assembly is smaller, and reducing the cost.

[0098] In the above two implementations, the electrode housing 121 is detachably connected or fixedly connected to the charging pile housing 5 .

[0099] Specifically, in some embodiments, the electrode shell 121 is detachably connected to the charging pile housing 5, thereby facilitating the assembly and disassembly of the charging terminal assembly and the charging pile housing 5. This not only improves the assembly efficiency of the charging terminal assembly and the charging pile housing 5, but also facilitates the maintenance or replacement of the charging terminal 1 and reduces costs.

[0100] Among them, the electrode shell 121 and the charging pile housing 5 can be detachably connected by a detachable connector (such as a screw), or by snap-on connection or the like, which is not strictly limited in this application.

[0101] In other embodiments, the electrode shell 121 is fixedly connected to the charging pile shell 5 in an integrally formed manner, thereby eliminating the assembly process between the electrode shell 121 and the charging pile shell 5, thereby simplifying the assembly process and also improving the stability and reliability of the connection between the electrode shell 121 and the charging pile shell 5.

[0102] In the above two implementations, Figure 4 and Figure 7 As shown, in addition to the stud 1212 , the seat 122 further includes a support wall 1221 and a top surface 1222 connected to the support wall 1221 , and the top surface 1222 is located between the electrode terminal 13 and the conductive support portion 2 .

[0103] The support wall 1221 can work together with the conductive support part 2 to provide mechanical support for the top surface 1222, thereby improving the supporting force of the top surface 1222, and also improving the stability of the overall installation of the seat 122; and when the seat 122 passes through the circuit board 3 and abuts against the charging pile housing 5 through the support wall 1221, the support wall 1221 can disperse the plugging and unplugging force applied by the user during charging, thereby reducing the probability of damage to the circuit board 3 due to the plugging and unplugging force and increasing the life of the circuit board 3.

[0104] Furthermore, if Figure 4 and Figure 7 As shown, the top surface 1222 is tilted relative to the vertical direction, so that the electrode terminal 13 set on the top surface 1222 is at a certain angle to the vertical direction. When the driver lifts the charging gun line to perform the plugging operation with the charging terminal 1, because the charging gun line often has a certain weight, it is more convenient to operate the plug end of the gun line connected to the pile by tilting upward, so the electrode terminal 13 is tilted downward and at a certain angle to the vertical direction to improve the user experience. On the other hand, the angle can save the space of the pile body in the direction perpendicular to the wall.

[0105] In the third implementation, Fig.10As shown, the seat 122 is not directly connected to the circuit board 3, that is, no components connected to the circuit board 3 are arranged on the seat 122, and no components connected to the seat 122 are arranged on the circuit board 3, that is, there is no direct connection between the seat 122 and the circuit board 3, thereby reducing the stress on the circuit board and reducing damage to the circuit board caused by long-term plugging and unplugging stress, and can save the assembly process between the seat 122 and the circuit board 3, thereby improving assembly efficiency.

[0106] Furthermore, if Fig.12 and Fig.13 As shown, the seat 122 at least covers the connection between the electrode terminal 13 and the conductive support part 2, thereby protecting the connecting components (such as the nut 141, the screw 143 or the rivet) between the electrode terminal 13 and the conductive support part 2, avoiding the erosion of the connecting components by dust and water vapor, and improving the service life of the connecting components.

[0107] In a specific application, the seat 122 is a plate-like structure, thereby reducing the volume of the seat 122, making the overall structure of the charging terminal 1 more compact, and increasing the stability of the overall structure. In order to increase the installation and positioning effect of the seat 122, a matching groove 1224 is provided on the seat 122 corresponding to the position of the connecting component. The installation orientation of the seat 122 can be determined through the relationship between the groove 1224 and the corresponding connecting component, thereby improving the assembly efficiency of the seat 122.

[0108] In this implementation, if Fig.11 As shown, the electrode housing 121 plays a role in accommodating and supporting the electrode terminal 13, and as shown in FIG. Fig. 9 As shown, the connection relationship between the electrode housing 121 and the charging pile housing 5 provides a fixed support for the electrode housing 121. The electrode housing 121 and the charging pile housing 5 are detachably connected, so as to facilitate the assembly and disassembly of the charging terminal assembly and the charging pile housing 5, thereby not only improving the assembly efficiency of the charging terminal assembly and the charging pile housing 5, but also facilitating the maintenance or replacement of the charging terminal 1 and reducing the cost.

[0109] Among them, the electrode shell 121 and the charging pile housing 5 can be detachably connected by a detachable connector (such as a screw), or by snap-on connection or the like, which is not strictly limited in this application.

[0110] The structure of the conductive support portion 2 is described in detail below. Specifically, the conductive support portion 2 includes a first connection segment 21 conductively connected to the charging terminal 1 and a second connection segment 22 conductively connected to the circuit board 3 . The first connection segment 21 is also connected to the second connection segment 22 .

[0111] The first connecting section 21 can increase the contact area between the conductive support part 2 and the charging terminal 1, thereby improving the stability and reliability of the connection. Similarly, the second connecting section 22 can increase the contact area between the conductive support part 2 and the circuit board 3, thereby improving the stability and reliability of the connection.

[0112] The first connecting section 21 and the second connecting section 22 may adopt a sheet-like structure, so that the contact area is larger, the connection is more stable, and it is easy to assemble.

[0113] Furthermore, the first connecting section 21 and the second connecting section 22 are rigid structures to form a rigid buffer force arm, so that the plugging and unplugging force applied by the user during charging can be buffered, thereby reducing the impact of the plugging and unplugging force on the circuit board 3, and thus reducing the probability of damage to the circuit board 3 due to the plugging and unplugging force, thereby protecting the circuit board 3. In addition, compared with the flexible structure, the rigid structure eliminates the need for components to clamp the flexible structure, thereby simplifying the structure and improving the assembly efficiency, and the rigid structure is easier to install, making the assembly efficiency higher. Moreover, the conductive support portion 2 formed by the first connecting section 21 and the second connecting section 22 can greatly reduce the length of the conductive support portion 2 compared with the soft wire solution in the prior art, thereby greatly reducing the space required for the charging terminal assembly.

[0114] Furthermore, if Figure 5 and Fig.12 As shown, the first connecting section 21 and the second connecting section 22 are also connected with an intermediate section 23, and the intermediate section 23 is a rigid structure. Compared with the flexible structure, the rigid structure eliminates the components for clamping the flexible structure, thereby simplifying the structure, reducing the cost, and improving the assembly efficiency. In addition, the rigid structure is easier to install, resulting in a higher assembly effect. The first connecting section 21, the second connecting section 22, and the intermediate section 23 are an integrated conductor structure, which is named differently only because of the different connection relationships with other components. It is not necessary to split into two / three or even more structural connections. Optionally, it can also be split into multiple connected structures.

[0115] The length of the middle section 23 can be set by the staff according to the wiring requirements. Usually, the connection positions of the conductive support part 2 and the charging terminal 1 and the circuit board 3 are not on the same or close connecting planes. The middle section 23 can form a certain angle with the first connecting section 21 and / or the second connecting section 22, thereby reducing the length of the middle section 23, thereby greatly shortening the overall length of the conductive support part 2, and thus greatly reducing the space occupied by the conductive support part 2.

[0116] In specific applications, the first connecting section 21, the second connecting section 22 and the middle section 23 can be made of conductive metal materials, and the present application does not strictly limit the specific metal material. In some embodiments, the first connecting section 21, the second connecting section 22 and the middle section 23 adopt a copper sheet structure, thereby improving the corrosion resistance of the conductive support part 2, thereby improving the life of the conductive support part 2. It is further preferred that the first connecting section 21, the second connecting section 22 and the middle section 23 are made of red copper, and the grade of red copper can be T1, T2, T3.

In addition, it can be understood by those skilled in the art that the utility model is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the utility model, and these variations and modifications all fall within the scope of protection claimed by the utility model.
