Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging, and in particular to a conductive module, a plug connector, a charging connector and a charging mechanism. Background Art

[0002] Conductive charging is a common charging method for existing electric vehicles or plug-in hybrid vehicles. Automakers often place sockets in different locations on the car (side, front, or rear) to connect to plugs (charging guns) installed on cables. This connection method poses certain safety risks because it requires manual operation by the user. At the same time, it is not convenient for manual operation in certain specific application scenarios. To solve the above problems, conductive automatic charging equipment has become an emerging charging solution, improving charging efficiency and convenience while ensuring charging safety. However, the connectors in the existing technology still have certain limitations in application:

[0003] 1. After the male and female ends of the charging connector are connected, the connection order of the PE / CP / DC+ / DC- electrodes cannot be adjusted;

[0004] 2. Some connectors use a traditional pinhole structure, which requires very high positioning accuracy of the back-end actuator and has a large insertion and removal force. This process is prone to significant wear and tear, seriously affecting the life of the connector.

[0005] 3. When adjusting the charging current, it is achieved by controlling the number of conductive contacts on the electrode. Due to the limitation of the electrode space, it is impossible to control the current by increasing the number of electrodes;

[0006] 4. The male and female connectors use ring conductors to compress or insert to establish an electrical connection. This structure requires multiple ring structures for the PE / CP / DC+ / DC- electrode connections, which makes the charging connector structure complex. In addition, to ensure the conduction sequence of the PE / CP / DC+ / DC- electrodes, the PE / CP / DC+ / DC- electrodes on the male and female ends need to be positioned in the same position, which brings inconvenience to use. Summary of the Invention

[0015] According to an embodiment of the present invention, the socket connector includes a socket electrode, which is cylindrical in shape, and the plug connector contacts the socket electrode through the elastic contact fingers to form an electrical connection.

[0016] According to one embodiment of the present invention, the socket connector includes a socket electrode, and the socket connector also includes an insulating mounting seat.

[0048] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0050] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0051] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0054] like Figure 1As shown, the purpose of the present invention is to provide a conductive module, a plug connector, a charging connector and a charging mechanism, including a plug connector and a socket connector, the plug connector is configured in the ground unit, the socket connector is configured in the vehicle unit, and is suitable for Figure 1 The side charging shown is also applicable to chassis charging. The plug connector of the present invention can control the size of the charging current and the connection sequence of PE, DC+ / -, and CP. The following is a detailed description of the embodiment.

[0055] Embodiment 1 of the present invention:

[0056] like Figure 2-20 As shown, the conductive module of this embodiment includes an annular mounting seat 1 and a conductive connector 2. The annular mounting seat 1 and the conductive connector 2 cooperate to control the connection sequence. Specifically, at least two internal electrodes 11 are configured inside the annular mounting seat 1, and the seat body 14 of the annular mounting seat 1 is provided with at least two mounting positions 13 along the radial direction and the axial direction. Preferably, the mounting position 13 is formed as a through hole, and the conductive connector 2 is detachably mounted on the mounting position 13, wherein at least one conductive connector 2 is electrically connected to one of the internal electrodes 11, and at least one conductive connector 2 is electrically connected to the other internal electrode 11. In this way, the conductive connector 2 can be selected and assembled according to the connection sequence of the internal electrodes 11, so that the connection sequence of the internal electrode 11 and the external electrode unit can be adjusted, thereby solving the technical problem that the electrode connection sequence on the charging connector in the prior art cannot be adjusted.

[0057] Generally, electric vehicle charging connectors utilize multiple ring-shaped structures. To ensure safe charging, the electrodes must be connected in the order of PE, DC+ / -, and CP. Consequently, each ring-shaped structure and its associated electrodes are configured differently. Due to space and structural limitations, the connection order of the multiple electrode groups is fixed and cannot be adjusted, limiting the application of these charging connectors. This embodiment utilizes selectively assembled conductive connectors 2 to adjust the connection order between the internal electrodes 11 and the external electrode units. This allows the conductive module to be used not only in applications where the electrode connection order is restricted, but also in other applications where the connection order is not restricted.

[0058] like Figure 2 、 4As shown in Figures 5 and 6, the annular mounting seat 1 and the internal electrode 11 of this embodiment are fixedly assembled. Specifically, the inner wall of the annular mounting seat 1 is provided with multiple groups of mounting grooves 141 formed along the circumferential direction, and the multiple groups of mounting grooves 141 are arranged in parallel. The internal electrode 11 includes a conductive plate 111 and a mounting electrode 112. The conductive plate 111 and the mounting electrode 112 are fixedly connected. A plug-in protrusion 1122 corresponding to the position of the mounting groove 141 is formed on the mounting electrode 112. The plug-in protrusion 1122 is inserted into the mounting groove 141 to form a fixed assembly between the annular mounting seat 1 and the mounting electrode 112, thereby connecting the annular mounting seat 1 and the internal electrode 11.

[0059] Furthermore, in this embodiment, partition grooves 12 are provided between adjacent mounting grooves 141 , so that after an external workpiece is inserted into the partition groove 12 , adjacent internal electrodes 11 can be isolated, thereby ensuring a safe electrical distance between the internal electrodes 11 .

[0060] like Figure 4 、 5 6, the internal electrode 11 of this embodiment is electrically connected to the external electrode unit with the help of the conductive connector 2. Specifically, an avoidance hole 1121 corresponding to the position of the through hole is formed on the mounting electrode 112, and the mounting electrode 112 is fixedly assembled on the inner wall of the base 14. One end of the conductive connector 2 is fixedly connected to the mounting electrode 112, and the other end of the conductive connector 2 passes through the avoidance hole 1121 and the through hole in sequence and is electrically connected to the external electrode unit. In this way, the internal electrode 11 is electrically connected to the external electrode.

[0061] Preferably, the internal electrode 11 of this embodiment only includes the conductive plate 111 , and the conductive plate 111 is directly electrically connected to the conductive connector 2 .

[0062] like Figure 5 As shown, both ends of the conductive plate 111 of this embodiment are provided with wiring terminals 1111, and the two wiring terminals 1111 are arranged on the side of the conductive plate 111 close to the center of the annular mounting base 1. In this way, the space of the conductive module can be fully utilized, and at the same time, a safe electrical distance between each wiring terminal 1111 is guaranteed, making the overall structure more compact.

[0063] like Figure 3 and 6As shown, the conductive connector 2 is configured as an elastic contact finger. A first stopper 22 and a second stopper 23 are provided at both ends of the elastic contact finger's housing. A seat stopper protrusion 142 corresponding to the position of the second stopper 23 is provided on the inner wall of the through-hole. A mounting electrode stopper protrusion 1123 corresponding to the position of the first stopper 22 is formed on the inner wall of the avoidance hole 1121. When the elastic contact finger passes through the through-hole and avoidance hole 1121, the first stopper 22 abuts against the mounting electrode stopper protrusion 1123, and the second stopper 23 abuts against the seat stopper protrusion 142, thereby limiting the elastic contact finger. Furthermore, the elastic contact head 21 of the elastic contact finger can promptly and effectively clean the oxide film on the surface of the external electrode unit, ensuring reliable contact. Compared with a planar axial pogopin contact method, under the same current-carrying conditions, it does not require a large axial docking pressure, has smaller docking resistance, and has lower output strength requirements for the rear-end actuator.

[0064] Embodiment 2 of the present invention:

[0065] This embodiment also provides a plug connector. The difference between this embodiment and the first embodiment is that Figure 10 As shown, the annular mounting base 1 of the first embodiment is a whole. The annular mounting base 1 of this embodiment includes multiple sub-mounts 15. The multiple sub-mounts 15 are detachably installed as a whole to form the annular mounting base 1. Each sub-mount 15 is configured with at least one conductive connector 2. The interior of the annular mounting base 1 is configured with at least one internal electrode 11. At least one conductive connector 2 is electrically connected to the internal electrode 11. In this way, the current can be controlled by controlling the number of sub-mounts 15 and the conductive connectors 2 thereon.

[0066] Furthermore, at least one conductive part is configured inside the sub-mount 15, and the conductive part is electrically connected to the internal electrode 11. The base body 14 of the sub-mount 15 is provided with at least two mounting positions 13 along the radial direction and the axial direction; the conductive connector 2 is detachably mounted on the mounting position 13, and the conductive connector 2 is electrically connected to the conductive part. The connection sequence of the internal electrode 11 can be controlled by selectively assembling the conductive connector 2 in the radial direction and the axial direction, and the conductive connector 2 can be selectively assembled in the radial direction and the axial direction.

[0067] According to a technical solution of the present invention, Figure 12 As shown, the conductive connecting member 2 is configured as an elastic contact finger, and the conductive member is configured as a conductive connecting wire 1532. One end of the conductive connecting wire 1532 is connected to the elastic contact finger, and the other end of the conductive connecting wire 1532 is connected to the conductive plate 111, so that the elastic contact finger is electrically connected to the internal electrode 11.

[0068] According to another technical solution of the present invention, Figure 11As shown, the conductive member is configured as a copper electrode 1531, the mounting electrode 112 and the conductive plate 111 of the internal electrode 11 are separately configured, and the copper electrode 1531 is assembled between the mounting electrode 112 and the conductive plate 111. One side of the copper electrode 1531 is fixedly connected to the mounting electrode 112, and the other side of the copper electrode 1531 is fixedly connected to the conductive plate 111, so that the elastic contact finger forms an electrical connection with the internal electrode 11.

[0069] like Figure 8 and 10 As shown, in order to meet the charging needs of electric vehicles, four groups of internal electrodes 11, conductive connectors 2 and conductive parts are provided on the sub-mount 15 of this embodiment to divide the sub-mount 15 into four power connection areas, which are plug CP, plug DC+ / - and plug PE power connection areas.

[0070] Furthermore, to ensure charging safety, the plug electrodes of this embodiment are equipped with resilient contact fingers on submounts 15, so that the four power contact areas of the plug electrodes contact external electrodes in the order of plug PE, plug DC+ / -, and plug CP. Specifically, the plug electrodes are arranged from bottom to top in a first layer of submounts 15, a second layer of submounts 15, a third layer of submounts 15, a fourth layer of submounts 15, and so on. First, the power contact area corresponding to plug PE on the first layer of submounts 15 is equipped with resilient contact fingers, while the other power contact areas are not equipped with resilient contact fingers. This allows the grounded plug PE to contact the external electrodes first, providing grounding protection. Then, the power contact area corresponding to plug DC+ / - on the second layer of submounts 15 is equipped with resilient contact fingers, while the power contact area corresponding to plug CP is not equipped with resilient contact fingers. Finally, the power contact area corresponding to plug CP on the third layer of submounts 15 is equipped with resilient contact fingers. In this way, the four power contact areas of the plug electrodes contact external electrodes in the order of plug PE, plug DC+ / -, and plug CP.

[0071] In summary, the plug connector of this embodiment can control both the size of the charging current and the structural order of the internal electrodes 11 .

[0072] like Figure 7 、 89. A limiting structure is provided on the submount 15 of this embodiment to facilitate the installation of adjacent submounts 15 together. Specifically, the limiting structure includes a concave table 152 and a convex table 151. The first end surface of the submount 15, near the internal electrode 11, is concave to form the concave table 152, and the second end surface of the submount 15, near the electrode side, is convex to form the convex table 151. Adjacent submounts 15 are fixedly assembled by extending the convex table 151 into the concave table 152 in the axial direction. Due to the limiting properties of the concave table 152 and the convex table 151, adjacent submounts 15 can be quickly stacked and assembled.

[0073] Preferentially, as Figure 11 As shown, one end of the mounting electrode 112 of this embodiment is higher than the concave table 152, so that the plug electrode, the concave table 152 and the sub-mounting seat 15 cooperate to form a groove 1521. When the adjacent sub-mounting seat 15 is installed, the boss 151 extends into the groove 1521 and is limited and cannot move in the radial direction.

[0074] Furthermore, the sub-mounting seat 15 of this embodiment is provided with a positioning and anti-rotation structure. Specifically, the sub-mounting seat 15 is formed with an inwardly concave notch 1522 on the inner wall near the concave table surface 152, and a anti-rotation member 1511 corresponding to the position of the notch 1522 is formed on the outer peripheral surface of the boss 151. The anti-rotation member 1511 protrudes from the outer peripheral surface of the boss 151. When adjacent sub-mounting seats 15 are stacked and assembled, the anti-rotation member 1511 is inserted into the notch 1522, so that no relative rotation will occur between adjacent sub-mounting seats 15.

[0075] Embodiment 3 of the present invention:

[0076] This embodiment includes the plug connector of the second embodiment and also includes a socket connector 3. The plug connector is inserted into the socket electrode 31 to form an electrical connection. Specifically, Figure 13 、 14 As shown in Figures 1 and 17, the socket connector 3 includes a socket electrode 31, which is cylindrical. Preferably, the socket electrode 31 is composed of four arc-shaped electrodes, and an isolation gap is provided between adjacent arc-shaped electrodes. After the plug connector is inserted into the socket connector 3, the contact 21 of the elastic contact finger contacts the socket electrode 31 to form an electrical connection. Since the non-contact end of the elastic contact finger is connected to the internal electrode 11, the socket electrode 31 forms an electrical connection with the internal electrode 11.

[0077] like Figure 13 、 14As shown in Figures 15 and 16, the charging connector of this embodiment further includes an insulating mounting seat 32, and the socket electrode 31 is plugged into the insulating mounting seat 32. Specifically, an annular limiting protrusion 323 is extended from the inner wall of the first end of the insulating mounting seat 32 in the radial direction, and a bearing plate 321 is provided at the second end of the insulating mounting seat 32 to support the plug electrode. The bearing plate 321 and the inner wall of the insulating mounting seat 32 are gap-fitted, and the socket electrode 31 is inserted from the gap and abuts against the annular limiting protrusion 323.

[0078] Furthermore, the inner wall of the insulating mounting seat 32 of this embodiment extends a plurality of groups of isolation strips 322 along the radial direction, and the plurality of isolation strips 322 are arranged in parallel. The isolation strips 322 are fixedly connected to the supporting plate 321 to isolate the gap between the supporting plate 321 and the inner wall of the insulating mounting seat 32 into a plurality of small gaps, so that the socket electrode 31 cannot shake after being inserted into the insulating mounting seat 32. A rotation-stop groove 154 corresponding to the position of the isolation strip 322 is formed on the outer wall of the sub-mounting seat 15, and the isolation strip 322 extends into the rotation-stop groove 154 to prevent the insulating mounting seat 32 and the socket electrode 31 thereon from rotating relative to the plug electrode.

[0079] like Figure 16 、 17 As shown, the charging connector of this embodiment also includes a mounting bracket 33, which is made of an insulating material and is disposed within the annular mounting base 1. The mounting bracket 33 is arranged in a cross shape, and the supporting ribs on the mounting bracket 33 extend into the partition groove 12 to form a fixed connection, thereby providing support for the annular mounting base 1 and the assembled parts thereon. In addition, the mounting bracket 33 is provided with a mounting channel, and the mounting channel is provided with a connecting shaft. Preferably, the connecting shaft is configured as a stud to connect the charging connector to other parts, such as a charging station. Preferably, the mounting bracket 33 is arranged along the central axis of the annular mounting base 1 to facilitate ensuring balanced support.

[0081] Embodiment 4 of the present invention:

[0082] This embodiment provides a charging mechanism, which includes the above-mentioned charging connector. The charging mechanism uses the charging connector to charge a charged vehicle, such as an electric vehicle.

[0083] Based on the above structure, the working principle of the charging connector of this embodiment is as follows:

[0084] When charging is required, the charging current and the connection sequence of the electrodes are selected based on the charged carrier. Taking an electric vehicle as an example: the number of elastic contact fingers or the number of sub-mounts 15 to be installed is selected based on the required charging current of the electric vehicle; elastic contact fingers are selected to be installed in the radial and axial directions of the annular mount 1 based on the connection sequence of the internal electrodes 11. After the above preparations are completed, the plug electrode is inserted into the socket electrode 31 to form an electrical connection. During the docking process, the plug PE electrode and the socket electrode 31 first contact to form a grounding protection, then the plug DC+ / - electrode and the socket electrode 31 contact, and finally the plug CP electrode and the socket electrode 31 contact. After docking is completed, the plug CP electrode is first energized. When the CP electrode and the socket electrode 31 are detected to be in contact, the plug DC+ / - electrode is energized to output power. If the CP electrode and the socket electrode 31 are detected to be not in contact, the plug DC+ / - electrode is not energized, and the electric vehicle is charged in this way.

[0085] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
