Description

Technical Field

[0002] With the increasing development of electronic technology, a connection can be established between two modules / devices through a connector to transmit data, power and other signals between the modules.

[0003] Currently, multiple different connectors are typically installed between modules, with each connector establishing a connection in sequence to achieve sequential connection of different signals between the modules. For example, a low-voltage connector, a high-voltage connector, and a signal connector are installed between the battery module and the power module. The low-voltage connector can be connected first, then the high-voltage connector, and finally the signal connector, to achieve sequential connection of different signals between the battery module and the power module. This allows low-voltage electricity to be transmitted through the low-voltage connector, high-voltage electricity to be transmitted through the high-voltage connector, and communication and data exchange through the signal connector.

[0166] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0167] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0168] With the advancement of electronic technology, two modules / devices can be connected via connectors to transmit signals such as data and power between the modules. Currently, multiple different connectors are typically installed between modules, and each connector establishes a connection in sequence to achieve the sequential connection of different signals between the modules.

[0169] Figure 1 This is a schematic diagram of the structure of a connector. Figure 1 As shown, the battery module and power module transmit low voltage electricity through the low-voltage connector, transmit high voltage electricity through the high-voltage connector, and communicate and exchange data through the signal connector. When connecting the battery module and power module, the installer needs to connect the low-voltage connector, high-voltage connector, and signal connector in sequence to ensure that the different signals between the battery module and power module are connected in a timely manner.

[0170] This method has the problem that the multiple connectors occupy a larger panel installation area and each connector needs to be installed separately, which increases the assembly time.

[0171] In light of this, the present application proposes a plug-in component that integrates multiple plug-in components used to connect different signals into a single plug-in component. The integrated plug-in component can be equipped with multiple conductive components. During the plug-in process, the multiple conductive components are electrically connected at different times, sequentially establishing different signal connections for the modules. The integrated plug-in component reduces the installation footprint of the panel. When connecting two modules, only one set of plug-in components needs to be installed, reducing assembly time.

[0172] The following describes in detail how the present application performs chronological electrical connection of plug-in components using specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The following embodiments of the present application are described in conjunction with the accompanying drawings.

[0173] Figure 2 This is a schematic diagram of the structure of a plug-in component provided in an embodiment of the present application. Figure 2 As shown, the first plug component 10 includes a plurality of first conductive components 11 .

[0174] The first conductive component 11 can be any electrically connectable component, such as a conductive pin, a conductive socket, or a conductive terminal. When the first conductive component 11 is a conductive pin, the second conductive component 21 can be a conductive socket or a conductive terminal. When the first conductive component 11 is a conductive socket or a conductive terminal, the second conductive component 21 can be a conductive pin. This embodiment of the application does not limit the form of the first conductive component 11.

[0175] The plurality of first conductive components 11 correspond to the plurality of second conductive components 21 of the second plug component 20 ; wherein, during the plugging process of the first plug component 10 and the second plug component 20 , the electrical connection moments of the plurality of first conductive components 11 and the corresponding second conductive components 21 are different.

[0176] For example, one first conductive component 11 is electrically connected to one second conductive component 21; or, multiple first conductive components 11 are electrically connected to one second conductive component 21; or, one first conductive component 11 is electrically connected to multiple second conductive components 21; or, multiple first conductive components 11 are electrically connected to multiple second conductive components 21. The correspondence between the first conductive component 11 and the second conductive component 21 only indicates the correspondence of the electrical connection relationship between the first conductive component 11 and the second conductive component 21. The embodiments of the present application do not limit the number of components actually connected between the first conductive component 11 and the second conductive component 21.

[0177] The electrical connection time of the first conductive component 11 and the corresponding second conductive component 21 is the same; the electrical connection time of different first conductive components 11 and the corresponding second conductive components 21 is different.

[0178] In summary, the first plug-in component includes multiple first conductive components. During the plug-in process between the first and second plug-in components, different first conductive components are electrically connected to their corresponding second conductive components at different times. Two modules can be connected via a single set of plug-in components, enabling sequential connection of different signals. The integration of multiple conductive components in the first plug-in component reduces the panel footprint. Connecting two modules requires only one set of plug-in components, reducing assembly time.

[0179] The embodiment of the present application provides a second plug-in component. Figure 2 As shown, the second plug component 20 includes a plurality of second conductive components 21 .

[0180] The second conductive component 21 can be any electrically connectable component, such as a conductive pin, a conductive socket, or a conductive terminal. When the second conductive component 21 is a conductive pin, the first conductive component 11 can be a conductive socket or a conductive terminal. When the second conductive component 21 is a conductive socket or a conductive terminal, the first conductive component 11 can be a conductive pin. This embodiment of the application does not limit the form of the second conductive component 21.

[0181] The plurality of second conductive components 21 correspond to the plurality of first conductive components 11 of the first plug component 10 ; wherein, during the plugging process of the first plug component 10 and the second plug component 20 , the electrical connection moments of the plurality of first conductive components 11 and the corresponding second conductive components 21 are different.

[0182] For example, one first conductive component 11 is electrically connected to one second conductive component 21; or, multiple first conductive components 11 are electrically connected to one second conductive component 21; or, one first conductive component 11 is electrically connected to multiple second conductive components 21; or, multiple first conductive components 11 are electrically connected to multiple second conductive components 21. The correspondence between the first conductive component 11 and the second conductive component 21 only indicates the correspondence of the electrical connection relationship between the first conductive component 11 and the second conductive component 21. The embodiments of the present application do not limit the number of components actually connected between the first conductive component 11 and the second conductive component 21.

[0183] The electrical connection time of the first conductive component 11 and the corresponding second conductive component 21 is the same; the electrical connection time of different first conductive components 11 and the corresponding second conductive components 21 is different.

[0184] In summary, the second plug-in component includes multiple second conductive components. During the plug-in process between the first and second plug-in components, different first conductive components are electrically connected to their corresponding second conductive components at different times. Two modules can be connected via a single set of plug-in components, enabling sequential connection of different signals. The integration of multiple conductive components in this first plug-in component reduces the panel footprint. Connecting two modules requires only one set of plug-in components, reducing assembly time.

[0185] For ease of description, the first plug component 10 and the second plug component 20 may also be referred to as the connector 1 . That is, the connector 1 may include the first plug component 10 and the second plug component 20 .

[0186] Figure 2 This is a schematic diagram of the structure of a plug-in component provided in an embodiment of the present application. Figure 2 As shown, the connector 1 includes: a first plug component 10 and a second plug component 20 ; the first plug component 10 includes a plurality of first conductive components 11 ; the second plug component 20 includes a plurality of second conductive components 21 .

[0187] The first plug-in component 10 and the second plug-in component 20 can be any component that can be plugged in and out of the connector, such as a socket and a plug. When the first plug-in component 10 is a socket, the second plug-in component 20 is a plug; when the first plug-in component 10 is a plug, the second plug-in component 20 is a socket. When the plug is inserted into the socket, connector 1 is plugged in; when the plug is removed from the socket, connector 1 is not plugged in.

[0188] The first conductive component 11 and the second conductive component 21 can be any electrically connectable component, such as a conductive pin and a conductive socket, or a conductive pin and a conductive terminal. The first conductive component 11 corresponds to the second conductive component 21. For example, the first plug component 10 includes N first conductive components 11, and the second plug component 21 includes M second conductive components 21. N and M are both positive integers and can be the same or different. One first conductive component 11 can be electrically connected to one second conductive component 21. Alternatively, multiple first conductive components 11 can be electrically connected to one second conductive component 21. Alternatively, one first conductive component 11 can be electrically connected to multiple second conductive components 21. Alternatively, multiple first conductive components 11 can be electrically connected to multiple second conductive components 21. The correspondence between the first conductive component 11 and the second conductive component 21 only indicates the correspondence of the electrical connection relationship between the first conductive component 11 and the second conductive component 21. This embodiment of the application does not limit the number of components that the first conductive component 11 and the second conductive component 21 actually connect.

[0189] In one possible implementation, the electrical connection positions of the multiple first conductive components 11 and / or the multiple second conductive components 21 are different, so that during the plugging process between the first plug component 10 and the second plug component 20, the electrical connection times of the multiple first conductive components 11 and the corresponding second conductive components 21 are different. For example, during the plugging process, the first conductive component 11 and the corresponding second conductive component 21 whose conductive parts are closer together are electrically connected first, and the first conductive component 11 and the corresponding second conductive component 21 whose conductive parts are farther apart are electrically connected later, thereby achieving different electrical connection times between the multiple first conductive components 11 and the corresponding second conductive components 21.

[0190] In another possible implementation, the lengths of the multiple first conductive components 11 and / or the multiple second conductive components 21 are different, so that during the plugging process of the first plug component 10 and the second plug component 20, the multiple first conductive components 11 and the corresponding second conductive components 21 are electrically connected at different times. After the first plug component 10 and the second plug component 20 are fully plugged in, the multiple first conductive components 11 and the corresponding second conductive components 21 are all electrically connected.

[0191] Continue as Figure 2 As shown, the first conductive component 11 includes a first conductive component a1, a first conductive component a2, and a first conductive component an; the second conductive component 21 includes a second conductive component b1, a second conductive component b2, and a second conductive component bn. The first conductive component a1 corresponds to the second conductive component b1; the first conductive component a2 corresponds to the second conductive component b2; and the first conductive component an corresponds to the second conductive component bn. The electrical connection times of the multiple first conductive components 11 and the corresponding second conductive components 21 are different. Specifically, the electrical connection times of the first conductive component a1 and the second conductive component b1 are the same; the electrical connection times of the first conductive component a2 and the second conductive component b2 are the same; and the electrical connection times of the first conductive component a3 and the second conductive component b3 are the same. The electrical connection times of the first conductive component a1, the first conductive component a2, and the first conductive component an are different.

[0192] It should be understood that the lengths of the plurality of first conductive components 11 and the lengths of the plurality of second conductive components 21 mentioned in the embodiment of the present application both refer to the lengths of effective electrical connection between the first conductive components 11 and the second conductive components 21 .

[0193] It should be understood that the different lengths of the multiple first conductive components 11 and / or the multiple second conductive components 21 mentioned in the embodiments of the present application refer to the lengths of the multiple first conductive components 11 and / or the multiple second conductive components 21 when the first plug component 10 and the second plug component 20 are not plugged in. After the first plug component 10 and the second plug component 20 are plugged in, the lengths of the multiple first conductive components 11 and the multiple second conductive components 21 may be the same or different, and this embodiment of the present application is not limited to this.

[0194] For example, the lengths of the multiple first conductive components 11 are different, and the lengths of the multiple second conductive components 21 are the same; during the plugging process, the longer first conductive component 11 is electrically connected to the corresponding second conductive component 21 first, and the shorter first conductive component 11 is electrically connected to the corresponding second conductive component 21 later; or, the lengths of the multiple first conductive components 11 are the same, and the lengths of the multiple second conductive components 21 are different; during the plugging process, the longer second conductive component 21 is electrically connected to the corresponding first conductive component 11 first, and the shorter second conductive component 21 is electrically connected to the corresponding first conductive component 11 later; or, the lengths of the multiple first conductive components 11 are different, and the lengths of the multiple second conductive components 21 are different, the longer first conductive component 11 has a longer corresponding second conductive component 21; the shorter first conductive component 11 has a shorter corresponding second conductive component 21; during the plugging process, the longer first conductive component 11 has a electrically connected to the corresponding second conductive component 21 first, and the shorter first conductive component 11 has a electrically connected to the corresponding second conductive component 21 later.

[0195] Continue as Figure 2 As shown, the first conductive component 11 includes a first conductive component a1, a first conductive component a2, and a first conductive component an; the second conductive component 21 includes a second conductive component b1, a second conductive component b2, and a second conductive component bn. The first conductive component a1 corresponds to the second conductive component b1; the first conductive component a2 corresponds to the second conductive component b2; and the first conductive component an corresponds to the second conductive component bn. The electrical connection time of the first conductive component a1 is earlier than the electrical connection time of the first conductive component a2, and the electrical connection time of the first conductive component a2 is earlier than the electrical connection time of the first conductive component an. When modules a and b are connected via connector 1, signals that need to be connected first can be connected to the conductive component with the earlier electrical connection time, for example, through the first conductive component a1 and the second conductive component b1; signals that need to be connected later can be connected to the conductive component with the later electrical connection time, for example, through the first conductive component a2 and the second conductive component b2, and so on. Modules a and b can establish multiple signal connections in chronological order via connector 1.

[0196] In summary, the connector's first plug-in component includes multiple first conductive components, and the second plug-in component includes multiple second conductive components. These multiple first conductive components and / or multiple second conductive components have different lengths, so that during the plug-in process between the first and second plug-in components, different first conductive components are electrically connected to corresponding second conductive components at different times. Two modules can be connected via a single connector, enabling sequential connection of different signals. This connector integrates multiple conductive components, reducing the panel's installation footprint. When connecting two modules, only one connector needs to be installed, reducing assembly time.

[0197] The connector proposed in this application can be used to connect power modules and battery modules, and can also be used to connect other modules that need to establish electrical connections for multiple signals in a time sequence. For ease of explanation, the embodiments of this application use the connector used to connect a power module and a battery module as an example.

[0198] Below Figure 2 On this basis, the structure of the plug-in component is further explained.

[0199] The lengths of the multiple first conductive components 11 and / or the multiple second conductive components 21 are different, so that the electrical connection moments of the multiple first conductive components 11 and the second conductive components 21 are different during the plugging process of the first plug component 10 and the second plug component 20.

[0200] The same lengths of the multiple first conductive components 11 indicate that, in the unplugged state, the ends of the multiple first conductive components 11 are aligned; the different lengths of the multiple first conductive components 11 indicate that, in the unplugged state, the ends of the multiple first conductive components 11 are not aligned; the same lengths of the multiple second conductive components 21 indicate that, in the unplugged state, the ends of the multiple second conductive components 21 are aligned; the different lengths of the multiple second conductive components 21 indicate that, in the unplugged state, the ends of the multiple second conductive components 21 are not aligned. After the first plug component 10 and the second plug component 20 are plugged in, the lengths of the multiple first conductive components 11 and the multiple second conductive components 21 may be the same or different, and this is not limited in this embodiment of the present application.

[0201] Possible implementations of the connector 1 are described based on the lengths and structures of the first conductive component 11 and the second conductive component 21 .

[0202] (1) The lengths of the plurality of first conductive components 11 are the same, and the lengths of the plurality of second conductive components 21 are different. That is, in the unplugged state, the ends of the plurality of first conductive components 11 are aligned, and the ends of the plurality of second conductive components 21 are not aligned.

[0203] Figure 3 This is a schematic diagram of the structure of the second plug-in component provided in the embodiment of the present application. Figure 3 As shown, the plurality of first conductive components 11 include a plurality of conductive pins 12 , and the lengths of the plurality of conductive pins 12 in the plugging direction are the same.

[0204] The second conductive component 21 includes a conductive socket 22 , and the conductive socket 22 has a conductive inner wall 23 . The lengths of the conductive inner walls 23 of the second conductive components 21 are different.

[0205] The conductive pin 12 can be any conductive pin, including, for example, a round pin, a square pin, or a flat pin. The conductive socket 22 can be any conductive socket, including, for example, a round socket, a square socket, or a flat socket. Optionally, the conductive pin 12 can correspond to the conductive socket 22. For example, if the conductive pin 12 is a round pin, the conductive socket 22 can also be a round socket; or, if the conductive pin 12 is a square pin, the conductive socket 22 can also be a square socket.

[0206] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the conductive pin 12 and the conductive socket 22 including the longer conductive inner wall 23 are electrically connected first, and the conductive pin 12 and the conductive socket 22 including the shorter conductive inner wall 23 are electrically connected later, thereby achieving different electrical connection times of multiple first conductive components 11 and second conductive components 21.

[0207] Continue as Figure 3As shown, for example, the conductive pins 12 include conductive pins a1, a2, and a3, and the conductive sockets 22 include conductive sockets b1, b2, and b3. The conductive pins a1, a2, and a3 are all the same length in the insertion direction. The conductive inner wall 23 of conductive socket b1 is longer than that of conductive socket b2, and the conductive inner wall of conductive socket b2 is longer than that of conductive socket b3.

[0208] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the conductive pin a1 and the conductive socket b1 first contact to achieve electrical connection, the conductive pin a2 and the conductive socket b2 then contact to achieve electrical connection, and the conductive pin a3 and the conductive socket b3 finally contact to achieve electrical connection, thereby achieving different electrical connection times for multiple first conductive components 11 and second conductive components 21.

[0209] Figure 4 This is a schematic diagram of the structure of the third plug-in component provided in the embodiment of the present application. Figure 4 As shown, the first conductive components 11 include a plurality of conductive pins 12, each having the same length in the plugging direction. The second conductive component 21 includes a retractable elastic conductive portion 24, each having different lengths in the unplugged state.

[0210] The elastic conductive portion 24 can be any retractable conductive component, such as a resilient contact or a resilient conductive sheet. The elastic conductive portion 24 has a conductive abutment surface 25 configured to abut against the conductive pin 12. In the unplugged state, the conductive abutment surfaces 25 of the multiple second conductive components 21 are positioned at different locations along the plugging direction.

[0211] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the conductive pin 12 and the conductive abutting surface 25 at the front are electrically connected first, and the conductive pin 12 and the conductive abutting surface 25 at the back are electrically connected later, thereby achieving different electrical connection times of multiple first conductive components 11 and second conductive components 21.

[0212] Continue as Figure 4 As shown, for example, the conductive pins 12 include conductive pins a1, a2, and a3, and the elastic conductive portion 24 includes elastic conductive portions b1, b2, and b3. The conductive pins a1, a2, and a3 are all the same length in the insertion direction. The conductive abutment surface of the elastic conductive portion b1 is positioned forward, the conductive abutment surface of the elastic conductive portion b2 is positioned in the center, and the conductive abutment surface of the elastic conductive portion b3 is positioned rearward.

[0213] During the plugging process between the first plug component 10 and the second plug component 20, the conductive pin a1 first contacts the elastic conductive portion b1 to achieve electrical connection. The elastic conductive portion b1 contracts under the plugging pressure, and when the conductive abutting surface 25 of the elastic conductive portion b1 contracts to the same position as the conductive abutting surface 25 of the elastic conductive portion b2, the conductive pin a2 contacts the elastic conductive portion b2 to achieve electrical connection. The elastic conductive portions b1 and b2 contract under the plugging pressure, and when the conductive abutting surfaces 25 of the elastic conductive portions b1 and b2 contract to the same position as the conductive abutting surfaces 25 of the elastic conductive portions b3, the conductive pin a3 contacts the elastic conductive portion b3 to achieve electrical connection. This allows the electrical connection of the multiple first conductive components 11 and the second conductive components 21 to be at different times.

[0214] (2) The lengths of the plurality of second conductive components 21 are the same, while the lengths of the plurality of first conductive components 11 are different. That is, in the unplugged state, the ends of the plurality of second conductive components 21 are aligned in the plugging direction, while the ends of the plurality of first conductive components 11 are not aligned in the plugging direction.

[0215] Figure 5 This is a structural diagram of the fourth plug-in component provided in the embodiment of the present application. Figure 5 As shown, the plurality of first conductive components 11 include a plurality of conductive pins 12 configured to electrically contact the second conductive component 21. The conductive pins 12 of the plurality of first conductive components 11 have different lengths in the plugging direction.

[0216] The second conductive component 21 includes a conductive socket 22 having a conductive inner wall 23 . The conductive inner walls 23 of the second conductive components 21 have the same length.

[0217] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the longer conductive pins 12 and the conductive sockets 22 are electrically connected first, and the shorter conductive pins 12 and the conductive sockets 22 are electrically connected later, thereby achieving different electrical connection times for multiple first conductive components 11 and second conductive components 21.

[0218] Continue as Figure 5 As shown, for example, the conductive pins 12 include conductive pins a1, a2, and a3, and the conductive sockets 22 include conductive sockets b1, b2, and b3. The length of conductive pin a1 in the insertion direction is greater than that of conductive pin a2, and the length of conductive socket a2 in the insertion direction is greater than that of conductive pin a3. The conductive inner walls of conductive sockets b1, b2, and b3 are the same length.

[0219] During the mating process between the first plug component 10 and the second plug component 20, the conductive pin a1 and the conductive socket b1 first contact to establish an electrical connection, the conductive pin a2 and the conductive socket b2 then contact to establish an electrical connection, and the conductive pin a3 and the conductive socket b3 finally contact to establish an electrical connection. This ensures that the electrical connection times of the multiple first conductive components 11 and the second conductive components 21 are different. After the first plug component 10 and the second plug component 20 are mated, the ends of the conductive pins a1, a2, and a3 are at different positions along the mating direction.

[0220] Figure 6 This is a structural diagram of the fifth plug-in component provided in the embodiment of the present application. Figure 6 As shown, the plurality of first conductive components 11 include a plurality of conductive pins 12 configured to electrically contact the second conductive component 21. The conductive pins 12 of the plurality of first conductive components 11 have different lengths in the plugging direction.

[0221] The second conductive component 21 includes a retractable elastic conductive portion 24. The elastic conductive portions 24 of the multiple second conductive components 21 are of the same length. The second conductive component 21 has a conductive abutment surface 25 configured to abut the conductive pin 12. The conductive abutment surfaces 25 of the multiple second conductive components 21 are positioned uniformly in the insertion direction.

[0222] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the longer conductive pin 12 and the elastic conductive part 24 are electrically connected first, and the shorter conductive pin 12 and the elastic conductive part 24 are electrically connected later, thereby achieving different electrical connection times of multiple first conductive components 11 and second conductive components 21.

[0223] Continue as Figure 6 As shown, for example, the conductive pins 12 include conductive pins a1, a2, and a3, and the elastic conductive portion 24 includes elastic conductive portions b1, b2, and b3. The length of conductive pin a1 is greater than that of conductive pin a2, and the length of conductive pin a2 is greater than that of conductive pin a3. The elastic conductive portions b1, b2, and b3 are all the same length.

[0224] During the plugging process between the first plug component 10 and the second plug component 20, the conductive pin a1 and the elastic conductive portion b1 first contact to achieve electrical connection. The elastic conductive portion b1 contracts under the plugging pressure, and when the conductive pin a2 reaches the conductive abutting surface 25 of the elastic conductive portion b2, the conductive pin a2 and the elastic conductive portion b2 contact to achieve electrical connection. The elastic conductive portions b1 and b2 contract under the plugging pressure, and when the conductive pin a3 reaches the conductive abutting surface 25 of the elastic conductive portion b3, the conductive pin a3 and the elastic conductive portion b3 contact to achieve electrical connection. This ensures that the electrical connection moments of the multiple first conductive components 11 and the second conductive components 21 are different.

[0225] Figure 7 This is a structural diagram of the sixth plug-in component provided in the embodiment of the present application. Figure 7 As shown, the first conductive components 11 include a plurality of conductive pins 12 configured to electrically contact the second conductive component 21. The conductive pins 12 of the first conductive components 11 are retractable structures, and the lengths of the conductive pins 12 of the first conductive components 11 in the plugging direction are different.

[0226] The second conductive component 21 includes a conductive socket 22 having a conductive inner wall 23 . The conductive inner walls 23 of the second conductive components 21 have the same length.

[0227] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the longer conductive pins 12 and the conductive sockets 22 are electrically connected first, and the shorter conductive pins 12 and the conductive sockets 22 are electrically connected later, thereby achieving different electrical connection times for multiple first conductive components 11 and second conductive components 21.

[0228] Continue as Figure 7 As shown, the conductive pins 12 include conductive pins a1, a2, and a3, and the conductive sockets 22 include conductive sockets b1, b2, and b3. Pins a1, a2, and a3 are retractable, and pin a1 is longer than pin a2, while socket a2 is longer than pin a3. The conductive inner walls of sockets b1, b2, and b3 are the same length.

[0229] During the plugging process between the first plug component 10 and the second plug component 20, the conductive pin a1 and the conductive socket b1 first contact to achieve electrical connection. The conductive pin a1 contracts under the plugging pressure, and the conductive pin a2 and the conductive socket b2 contact to achieve electrical connection. The conductive pins a1 and a2 contract under the plugging pressure, and the conductive pin a3 and the conductive socket b3 finally contact to achieve electrical connection. This allows the electrical connection of the multiple first conductive components 11 and the second conductive components 21 to be different at different times.

[0230] Figure 8 This is a structural diagram of the seventh plug-in component provided in the embodiment of the present application. Figure 8 As shown, the first conductive components 11 include a plurality of conductive pins 12 configured to electrically contact the second conductive component 21. The conductive pins 12 of the first conductive components 11 are retractable structures, and the lengths of the conductive pins 12 of the first conductive components 11 are different.

[0231] The second conductive component 21 has a conductive abutting surface 25 configured to abut against the conductive pin 12 ; wherein the conductive abutting surfaces 25 of the plurality of second conductive components 21 are at the same position in the plugging direction.

[0232] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the longer conductive pin 12 and the conductive abutment surface 25 are electrically connected first, and the shorter conductive pin 12 and the conductive abutment surface 25 are electrically connected later, thereby achieving different electrical connection times for multiple first conductive components 11 and second conductive components 21.

[0233] Continue as Figure 8 As shown, the conductive pins 12 include conductive pins a1, a2, and a3, and the conductive abutment surface 25 includes conductive abutment surfaces b1, b2, and b3. Pins a1, a2, and a3 are retractable, and pin a1 is longer than pin a2, while pin a2 is longer than pin a3. The conductive abutment surfaces b1, b2, and b3 are positioned identically in the insertion direction.

[0234] During the plugging process between the first plug component 10 and the second plug component 20, the conductive pin a1 first contacts the conductive abutting surface b1 to achieve electrical connection. The conductive pin a1 then contracts under the plugging pressure, and the conductive pin a2 then contacts the conductive abutting surface b2 to achieve electrical connection. The conductive pins a1 and a2 then contract under the plugging pressure, and the conductive pin a3 finally contacts the conductive abutting surface b3 to achieve electrical connection. This allows the electrical connection of the multiple first conductive components 11 and the second conductive components 21 to occur at different times.

[0235] (3) The lengths of the plurality of second conductive components 21 are different, and the lengths of the plurality of first conductive components 11 are different. That is, in the unplugged state, the ends of the plurality of second conductive components 21 are not aligned in the plugging direction, and the ends of the plurality of first conductive components 11 are not aligned in the plugging direction.

[0236] Figure 9 This is a structural diagram of the eighth plug-in component provided in the embodiment of the present application. Figure 9 As shown, the first conductive component 11 includes a retractable conductive pin 12 configured to be in electrical contact with the second conductive component 21 ; the conductive pins 12 of the plurality of first conductive components 11 have different lengths in the plugging direction.

[0237] The second conductive component 21 includes a retractable elastic conductive portion 24; the lengths of the elastic conductive portions 24 of the multiple second conductive components 21 are different; the second conductive component 21 has a conductive abutting surface 25, which is configured to abut against the conductive pin 12; wherein the conductive abutting surfaces 25 of the multiple second conductive components 21 are at different positions in the plugging direction.

[0238] During the plugging process of the first plug-in component 10 and the second plug-in component 20, the longer conductive pin 12 and the conductive abutment surface 25 located in the front are electrically connected first, and the shorter conductive pin 12 and the conductive abutment surface 25 located in the back are electrically connected later, thereby achieving different electrical connection times of multiple first conductive components 11 and second conductive components 21.

[0239] Continue as Figure 9 As shown, for example, the conductive pins 12 include conductive pins a1, a2, and a3, and the elastic conductive portion 24 includes elastic conductive portions b1, b2, and b3. Pins a1, a2, and a3 are retractable, and the length of pin a1 is greater than that of pin a2. The length of pin a2 is greater than that of pin a3. The conductive abutment surface 25 of elastic conductive portion b1 is positioned forward in the insertion direction, the conductive abutment surface 25 of elastic conductive portion b2 is positioned centrally in the insertion direction, and the conductive abutment surface 25 of elastic conductive portion b3 is positioned rearward in the insertion direction.

[0240] During the plugging process between the first plug component 10 and the second plug component 20, the conductive pin a1 first contacts the elastic conductive portion b1 to achieve electrical connection. The elastic conductive portion b1 and the conductive pin a1 then contract under the plugging pressure, causing the conductive pin a2 to contact the elastic conductive portion b2 to achieve electrical connection. Finally, the elastic conductive portion b1, the conductive pin a1, the elastic conductive portion b2, and the conductive pin a2 contract under the plugging pressure, causing the conductive pin a3 to contact the elastic conductive portion b3 to achieve electrical connection. This allows the electrical connection of the multiple first conductive components 11 and the second conductive components 21 to occur at different times.

[0241] The above describes possible implementations of the connector 1 based on the lengths and structures of the first conductive component 11 and the second conductive component 21. Furthermore, the structures of the multiple first conductive portions 11 can be identical or different. For example, the cross-sectional dimensions of the conductive pins 12 of the multiple first conductive components 11 can vary. The larger the cross-sectional dimensions of the conductive pins 12 of the first conductive component 11, the greater the current that the first conductive component 11 can carry. In specific implementations, these dimensions can be set based on actual needs, providing greater flexibility in the implementation of the first conductive component 11.

[0242] The inner diameters of the conductive sockets 22 of the multiple second conductive components 21 may also be different and may match the cross-sectional dimensions of the first conductive component 11, thereby achieving a stable electrical connection between the first conductive component 11 and the second conductive component 21. Specifically, the inner diameters may be set based on the cross-sectional dimensions of the conductive pins of the first conductive component 11.

[0243] It should be understood that the first conductive component 11 may include one or more conductive pins 12. By connecting multiple conductive pins 12 in parallel, the current load on the conductive pins can be shared, thereby enabling the first conductive component 11 to carry a larger current. Correspondingly, the second conductive component 21 may also include one or more conductive sockets 22, with each conductive pin 12 corresponding to a conductive socket 22. This embodiment of the present application is not limited to this, and specific settings can be made based on actual needs.

[0244] Figure 10 This is a structural diagram of the ninth plug-in component provided in the embodiment of the present application. Figure 10 As shown, the plurality of first conductive components 11 can be divided into a multi-level first conductive component group 31, and the plurality of second conductive components 21 can be divided into a multi-level second conductive component group 32;

[0245] The electrical connection time of the first conductive component group 31 and the second conductive component group 32 at the same level is the same, and the electrical connection time of the first conductive component group 31 and the second conductive component group 32 at different levels is different.

[0246] Continue as Figure 10As shown, as an example, the multiple first conductive components 11 can be divided into a first-level first conductive component group C1 and an n-level first conductive component group Cn, and the multiple second conductive components 21 can be divided into a first-level second conductive component group D1 and an n-level second conductive component group Dn. The electrical connection times of the first conductive component groups 31 and second conductive component groups 32 of different levels are different. Specifically, during the plug-in process of the first plug-in component 10 and the second plug-in component 20, the electrical connection times of the first-level first conductive component group C1 and the first-level second conductive component group D1 are the same; the electrical connection times of the n-level first conductive component group Cn and the n-level second conductive component group Dn are the same; and the electrical connection times of the first-level first conductive component group C1 and the n-level first conductive component group Cn are different.

[0247] For example, the first plug component 10 includes n-level first conductive component groups 31, and the second plug component 20 also includes n-level second conductive component groups 32. Each level of first conductive component group 31 may include multiple first conductive components 11, and each level of second conductive component group 32 may include multiple second conductive components 21; the first conductive components 11 and the second conductive components 21 correspond to each other.

[0248] During the plugging process, the electrical connection moments of the multiple first conductive components 11 of the first conductive component group 31 at the same level and the second conductive components 21 of the second conductive component group 32 at the same level are the same, and the electrical connection moments of the multiple first conductive components 11 of the first conductive component group 31 at different levels and the multiple second conductive components 21 of the second conductive component group 32 are different.

[0249] Continue as Figure 10As shown, as an example, multiple first conductive components 11 can be divided into a first-level first conductive component group C1 and an n-level first conductive component group Cn, and multiple second conductive components 21 can be divided into a first-level second conductive component group D1 and an n-level second conductive component group Dn; the first-level first conductive component group C1 includes: first conductive component a1-first conductive component ak, and the n-level first conductive component group Cn includes: first conductive component am-first conductive component an; the first-level second conductive component group D1 includes: second conductive component b1-second conductive component bk, and the n-level second conductive component group Dn includes: second conductive component bm-second conductive component bn. Among them, the electrical connection moments of the first-level first conductive component group C1 and the first-level second conductive component group D1 are the same, which means that the electrical connection moments of the first conductive component a1-first conductive component ak and the corresponding second conductive component b1-second conductive component bk are the same; the electrical connection moments of the n-level first conductive component group Cn and the n-level second conductive component group Dn are the same, which means that the electrical connection moments of the first conductive component am-first conductive component an and the corresponding second conductive component bm-second conductive component bn are the same; the electrical connection moments of the first-level first conductive component group C1 and the n-level second conductive component group Dn are different, which means that the electrical connection moments of (the first conductive component a1-first conductive component ak and the corresponding second conductive component b1-second conductive component bk) are different from the electrical connection moments of (the first conductive component am-first conductive component an and the corresponding second conductive component bm-second conductive component bn).

[0250] Figure 11 This is a schematic diagram of the structure of the tenth plug-in component provided in the embodiment of the present application. Figure 11 As shown, the multi-level first conductive component group 31 includes: a first-level first conductive component group 311, a second-level first conductive component group 312 and a third-level first conductive component group 313, which are sorted from high to low priority; the multi-level second conductive component group 32 includes: a first-level second conductive component group 321, a second-level second conductive component group 322 and a third-level second conductive component group 323, which are sorted from high to low priority; wherein, the higher the priority, the earlier the electrical connection time.

[0251] A possible implementation is: in the multi-level first conductive component group 31 , the first conductive component 11 with a higher priority has a longer length, and the first conductive components 11 at the same level have the same length; the conductive components in the multi-level second conductive component group 32 have the same length.

[0252] For example, in the unplugged state, the length of the first conductive component 11 of the first-level first conductive component group 311 is greater than the length of the first conductive component 11 of the second-level first conductive component group 312, and the length of the first conductive component 11 of the second-level first conductive component group 312 is greater than the length of the first conductive component 11 of the tertiary first conductive component group 313; the lengths of the first conductive components 11 of the first-level first conductive component group 311 are the same, the lengths of the first conductive components 11 of the second-level first conductive component group 312 are the same, and the lengths of the first conductive components 11 of the tertiary first conductive component group 313 are the same; the lengths of the second conductive component 21 of the first-level second conductive component group 321, the lengths of the second conductive component 21 of the second-level second conductive component group 322, and the lengths of the second conductive component 21 of the tertiary second conductive component group 323 are the same.

[0253] Another possible implementation is that in the multi-level second conductive component group 32 , the second conductive component 21 with a higher priority has a longer length, and the second conductive components 21 at the same level have the same length; the conductive components in the multi-level first conductive component group 31 have the same length.

[0254] For example, in the unplugged state, the length of the second conductive component 21 of the first-level second conductive component group 321 is greater than the length of the second conductive component 21 of the second-level second conductive component group 322, and the length of the second conductive component 21 of the second-level second conductive component group 322 is greater than the length of the second conductive component 21 of the tertiary second conductive component group 323; the lengths of the second conductive components 21 of the first-level second conductive component group 321 are the same, the lengths of the second conductive components 21 of the second-level second conductive component group 322 are the same, and the lengths of the second conductive components 21 of the tertiary second conductive component group 323 are the same; the lengths of the first conductive component 11 of the first-level first conductive component group 311, the lengths of the first conductive component 11 of the second-level first conductive component group 312, and the lengths of the first conductive component 11 of the tertiary first conductive component group 313 are all the same.

[0255] A third possible implementation is that, in the multi-level first conductive component group 31, the first conductive component 11 with a higher priority has a longer length, and the first conductive components 11 at the same level have the same length; in the multi-level second conductive component group 32, the second conductive component 21 with a higher priority has a longer length, and the second conductive components 21 at the same level have the same length.

[0256] For example, in the unplugged state, the length of the first conductive component 11 of the first-level first conductive component group 311 is greater than the length of the first conductive component 11 of the second-level first conductive component group 312, and the length of the first conductive component 11 of the second-level first conductive component group 312 is greater than the length of the first conductive component 11 of the tertiary first conductive component group 313; the lengths of the first conductive components 11 of the first-level first conductive component group 311, the lengths of the first conductive components 11 of the second-level first conductive component group 312, and the lengths of the first conductive components 11 of the tertiary first conductive component group 313 are the same; the length of the second conductive component 21 of the first-level second conductive component group 321 is greater than the length of the second conductive component 21 of the second-level second conductive component group 322, and the length of the second conductive component 21 of the second-level second conductive component group 322 is greater than the length of the second conductive component 21 of the tertiary second conductive component group 323; the lengths of the second conductive components 21 of the first-level second conductive component group 321, the lengths of the second conductive components 21 of the second-level second conductive component group 322, and the lengths of the second conductive components 21 of the tertiary second conductive component group 323 are the same.

[0257] During the plugging process of the connector 1, the electrical connection time of the first-level first conductive component group 311 and the first-level second conductive component group 321 is earlier than the electrical connection time of the second-level first conductive component group 312 and the second-level second conductive component group 322, and the electrical connection time of the second-level first conductive component group 312 and the second-level second conductive component group 322 is earlier than the electrical connection time of the tertiary first conductive component group 313 and the tertiary second conductive component group 323. During the plugging process of the connector 1, the electrical connection can be divided into three stages according to the time sequence.

[0258] Figure 12 This is a schematic diagram of the structure of a battery pack provided in an embodiment of the present application. Figure 12 As shown, the first plug-in component 10 can be installed on the power module 6, and the second plug-in component 20 can be installed on the battery module 5; or, the first plug-in component 10 can be installed on the battery module 5, and the second plug-in component 20 can be installed on the power module 6. Figure 12 The following description will be made by taking an example where the first plug-in component 10 is installed on the power module 6 and the second plug-in component 20 is installed on the battery module 5 .

[0259] The battery module 5 can be, for example, any module capable of storing electrical energy, such as a lithium-ion battery module 5, a lithium iron phosphate battery module 5, a nickel-metal hydride battery module 5, a lead-acid battery module 5, or the like. The power module 6 can be, for example, any module capable of performing voltage conversion, such as a DC / DC converter or a DC / AC converter. This embodiment of the present application uses the example of a power module 6 including a DC / DC converter as an example for illustration.

[0260] Connector 1 can be, for example, a plug-in connector 1, which can include a plug and a socket. After the battery module 5 and the power module 6 are assembled and connected via connector 1, the battery module 5 sends low-voltage electricity to the power module 6 via connector 1. The power module 6 converts the low-voltage electricity and outputs a boosted high-voltage electricity. The battery module 5 and the power module 6 communicate and exchange data via connector 1. When the power module 6 fails, the connection part of connector 1 can be unplugged to disconnect the power module 6 and the battery module 5. After that, the power module 6 can be removed and replaced.

[0261] It should be understood that the high voltage and low voltage mentioned in the embodiments of the present application are relative concepts, that is, low voltage refers to a lower voltage than high voltage. For example, 48V is low voltage and 220V is high voltage.

[0262] Because the low-voltage side of power module 6 contains a large capacitor, the voltage across it is zero when the capacitor is uncharged. When power module 6 and battery module 5 are assembled and connected, the battery module 5 attempts to charge the capacitor, which causes a large instantaneous current to flow through connector 1, causing it to spark and potentially damage it.

[0263] To address the potential damage to connector 1 during assembly and connection of power module 6 and battery module 5, a pre-charge unit is added to the low-voltage side of power module 6. During assembly and connection, battery module 5 can first charge the capacitors of power module 6 through the pre-charge unit, preventing a sudden surge of current on the capacitors and thus damage to connector 1. The battery module 5 then supplies power to power module 6 via the main power supply circuit.

[0264] Figure 13 This is a structural diagram of a pre-charge unit. Figure 13 As shown, the pre-charge unit 61 includes: a pre-charge group R, a main circuit relay KA, and a pre-charge circuit relay KAR. The main circuit relay KA is connected in series between the positive output terminal B+ of the battery module 5 and the low-voltage positive input terminal P+ of the power module 6. The negative input terminal B- of the battery module 5 is connected to the low-voltage negative input terminal P- of the power module 6. The pre-charge circuit relay KAR and the pre-charge resistor R are connected in series and then in parallel across the main circuit relay KA. The capacitor C of the power module 6 is connected in parallel between the low-voltage positive input terminal P+ and the low-voltage negative input terminal P- of the power module 6. The controller is connected to the control terminal of the main circuit relay KA and the control terminal of the pre-charge circuit relay KAR.

[0265] The main circuit relay KA and the pre-charge circuit relay KAR may be, for example, any relay that can be turned on or off based on a high-level or low-level signal, such as an electromagnetic relay.

[0266] When the battery module 5 is connected to the power module 6, the controller controls the pre-charge circuit relay KAR to be turned on and the main circuit relay KA to be turned off. At this time, the pre-charge circuit between the positive output terminal B+ of the battery module 5, the pre-charge resistor R, the capacitor C, and the negative output terminal B- of the battery module 5 is turned on, and the pre-charge resistor R can limit the current flowing through the capacitor C. The battery module 5 charges the capacitor C through the pre-charge resistor R, so that the capacitor can be charged smoothly and safely to avoid instantaneous large currents from damaging the connector 1. After the charging of the capacitor C is completed, the controller controls the pre-charge circuit relay KAR to be turned off and the main circuit relay KA to be turned on, so as to turn on the low-voltage main power supply circuit of the battery module 5 and the power module 6.

[0267] Figure 14 This is a schematic diagram of the structure of the second battery pack provided in the embodiment of the present application. Figure 14 As shown, the second device may include, for example: a pre-charging unit 61 , a DC / DC converter 62 and a communication unit 63 .

[0268] The pre-charge unit 61 may be, for example, any unit capable of limiting current, such as a resistor, an inductor, or other components. The DC / DC converter 62 may be, for example, a device that converts an input voltage, such as a boost converter. The communication unit 63 may be, for example, any unit capable of communicating with the outside world.

[0269] The first-level first conductive component group 311 includes a first pre-filled component 34; the first-level second conductive component group 321 includes a second pre-filled component 14. The first pre-filled component 34 is connected to the second pre-filled component 14 to achieve connection between the pre-filled units 61 in the first device and the second device. Figure 14 The following description is made by taking the second device as the power module 6 and the first device as the battery module 5 as an example.

[0270] The first pre-filled component 34 and the second pre-filled component 14 can be, for example, any component that can be electrically connected, such as a conductive pin, a conductive socket, a conductive terminal, etc. The first pre-filled component 34 and the second pre-filled component 14 can be electrically connected by plugging, for example; when the first pre-filled component 34 is a conductive pin, the second pre-filled component 14 can be a conductive socket or a conductive terminal; when the first pre-filled component 34 is a conductive socket or a conductive terminal, the second pre-filled component 14 can be a conductive pin. The embodiment of the present application does not limit the form of the first pre-filled component 34 and the second pre-filled component 14.

[0271] The secondary first conductive component group 312 includes a first power component 35 ; the secondary second conductive component group 322 includes a second power component 15 , and the first power component 35 is connected to the second power component 15 to achieve connection between the battery module 5 and the DC / DC converter 62 of the power module 6 .

[0272] The first power component 35 and the second power component 15 can each be any electrically connectable component, such as a conductive pin, a conductive socket, or a conductive terminal. The first power component 35 and the second power component 15 can be electrically connected by plugging. If the first power component 35 is a conductive pin, the second power component 15 can be a conductive socket or a conductive terminal. If the first power component 35 is a conductive socket or a conductive terminal, the second power component 15 can be a conductive pin. This embodiment of the application does not limit the form of the first power component 35 and the second power component 15.

[0273] The first pre-charge component 34 and the second pre-charge component 14 are electrically connected at the same time; the first power component 35 and the second power component 15 are electrically connected at the same time; the first pre-charge component 34 is electrically connected earlier than the first power component 35. When the battery module 5 and the power module 6 are assembled and connected, the first pre-charge component 34 and the second pre-charge component 14 are electrically connected first, the pre-charge circuits of the battery module 5 and the power module 6 are turned on, and the battery module 5 charges the capacitor in the power module 6 through a smaller current; the first power component 35 and the second power component 15 are then electrically connected, and the main power supply circuits of the battery module 5 and the power module 6 are turned on. By making the electrical connection moments of the conductive components of the connector different, different circuits can be established between the battery module 5 and the power module 6 in sequence, thereby avoiding damage to the connector. This method does not require the use of a main relay and a pre-charge relay to switch between the pre-charge circuit and the main power supply circuit, and the implementation method is simple.

[0274] Optionally, the three-stage first conductive component group 313 includes a first signal component 39 ; the three-stage second conductive component group 323 includes a second signal component 19 , so as to achieve connection between the battery module 5 and the communication unit 63 of the power module 6 .

[0275] The first signal component 39 and the second signal component 19 are electrically connected at the same time; the first power component 35 and the second power component 15 are electrically connected at the same time; the first signal component 39 is electrically connected later than the first power component 35. During assembly and connection of the battery module 5 and the power module 6, the first power component 35 and the second power component 15 are electrically connected first, followed by the first signal component 39 and the second signal component 19, thus completing the communication circuit between the battery module 5 and the power module 6.

[0276] Optionally, the plurality of first conductive components 11 include a first in-place detection component 45; the plurality of second conductive components 21 include a second in-place detection component 46; the first in-place detection component 45 is connected to the second in-place detection component 46 to detect the connection between the battery module 5 and the power module 6; wherein the electrical connection time of the first in-place detection component 45 is later than the electrical connection time of the first power component 35. The electrical connection time of the first in-place detection component 45 and the second in-place detection component 46 are the same; the electrical connection time of the first power component 35 and the second power component 15 are the same; the electrical connection time of the first in-place detection component 45 is later than the electrical connection time of the first power component 35. When the electrical connection between the first in-place detection component 45 and the second detection component 15 is detected, it indicates that the first power component 35 and the second power component 15 have been connected.

[0277] In one possible implementation, the first in-place detection component 45 may include a first sub-in-place detection component and a second sub-in-place detection component; the first sub-in-place detection component is electrically connected to the second sub-in-place detection component. The second in-place detection component 46 may include a third sub-in-place detection component and a fourth sub-in-place detection component. The third sub-in-place detection component is connected to the first terminal of the battery management module 52, and the fourth sub-in-place detection component is connected to the second terminal of the battery management module 52. The battery management module 52 sends a detection signal through the first terminal and receives input signals through the second terminal. When the first plug-in component 10 and the second plug-in component 20 are connected, the first sub-in-place detection component is electrically connected to the third sub-in-place detection component, and the second sub-in-place detection component is electrically connected to the fourth sub-in-place detection component. The first terminal and the second terminal of the battery management module 52 form a communication loop, and the second terminal of the battery management module 52 can receive the detection signal sent by the first terminal, indicating that the plug-in components are connected. When the connection between the first plug-in component 10 and the second plug-in component 20 becomes loose, the connection between the first in-place detection component 45 and the second in-place detection component 46 is first disconnected, and the second terminal of the battery management module 52 cannot detect the detection signal sent by the first terminal. By providing the first in-place detection component 45 and the second in-place detection component 46, it is possible to detect whether the first plug-in component 10 and the second plug-in component 20 are reliably connected.

[0278] Optionally, the first power component 35 includes a first low-voltage power component 37; the second power component 15 includes a second low-voltage power component 17; the first low-voltage power component 37 is electrically connected to the second low-voltage power component 17; the first low-voltage power component 37 and the second low-voltage power component 17 are used to transmit the voltage output by the battery module 5. The first power component 35 includes a first high-voltage power component 38; the second power component 15 includes a second high-voltage power component 18; the first high-voltage power component 38 is electrically connected to the second high-voltage power component 18; the first high-voltage power component 38 and the second high-voltage power component 18 are used to transmit the voltage output by the DC / DC converter 62.

[0279] Below Figure 14 The specific circuit connection between the battery module 5 and the pre-charge unit 61 of the power module 6 is described below.

[0280] Figure 15 This is a schematic diagram of the structure of a pre-charge unit provided in an embodiment of the present application. Figure 15 As shown, the first low-pressure power component 37 includes: a first sub-low-pressure power component 41 and a second sub-low-pressure power component 42. The second low-pressure power component 17 includes: a third sub-low-pressure power component 26 and a fourth sub-low-pressure power component 27.

[0281] The first sub-low-voltage power component 41 is connected to the low-voltage first input terminal of the DC / DC converter 62; the second sub-low-voltage power component 42 is connected to the low-voltage second input terminal of the DC / DC converter 62; the third sub-low-voltage power component 26 is connected to the first output terminal of the battery module 5; and the fourth sub-low-voltage power component 27 is connected to the second output terminal of the battery module 5.

[0282] The first pre-filling component 34 includes a first sub-pre-filling component 43 and a second sub-pre-filling component 44 ; the second pre-filling component 14 includes a third sub-pre-filling component 47 and a fourth sub-pre-filling component 48 .

Figure 13 Compared with the implementation of the pre-charge unit shown in FIG, the relay KAR and the relay KA are saved, and the circuit structure is simplified.

[0289] Figure 16 This is a structural diagram of another pre-charge unit provided in an embodiment of the present application. Figure 16 As shown, the pre-charge unit includes: a resistor R.

[0290] In one possible implementation, one end of resistor R serves as the first input of pre-charging unit 61, connected to the first sub-pre-charging component 43. The other end of resistor R serves as the first output of pre-charging unit 62, connected to the low-voltage first input of DC / DC converter 62. The second input of pre-charging unit 61 is connected to the second sub-pre-charging component 44, and the second output of pre-charging unit 61 is connected to the low-voltage second input of DC / DC converter 62.

[0291] It should be understood that the low-voltage first input terminal of the DC / DC converter 62 can be the positive input terminal P+, and the low-voltage second input terminal of the DC / DC converter 62 can be the negative input terminal P-; or, the low-voltage first input terminal of the DC / DC converter 62 can be the negative input terminal P-, and the low-voltage second input terminal of the DC / DC converter 62 can be the positive input terminal P+. Figure 16 The following description is made by taking the low-voltage first input terminal of the DC / DC converter 62 as the positive input terminal P+ and the low-voltage second input terminal of the DC / DC converter 62 as the negative input terminal P− as an example.

[0292] In another possible implementation, resistor R includes resistor R1 and resistor R2. One end of resistor R1 serves as the first input of pre-charge unit 61 and is connected to the first sub-pre-charge component 43. The other end of resistor R1 serves as the first output of pre-charge unit 62 and is connected to the low-voltage first input of DC / DC converter 62.

The other end of resistor R serves as the first output of pre-charge unit 62 and is connected to low-voltage positive input terminal P+ of DC / DC converter 62. For illustrative purposes, the second input of pre-charge unit 61 is connected to second sub-pre-charge component 44, and the second output of pre-charge unit 61 is connected to low-voltage negative input terminal P- of DC / DC converter 62.

[0296] The length of the first sub-pre-charging component 43 and the second sub-pre-charging component 44 of the connector 1 is greater than the length of the first sub-low-voltage power component 41 and the second sub-low-voltage power component 42. When the battery module 5 is connected to the power module 6 through the connector 1, the pre-charging circuit can be turned on first to charge the capacitor of the power module through a smaller circuit, and then the main power supply circuit can be turned on to avoid damage to the connector 1 due to excessive instantaneous current when the battery module 5 and the power module 6 are connected.

[0297] Furthermore, the power module 6 includes: a circuit board; the first plug-in component 10 / the second plug-in component 20 can be welded on the circuit board. The circuit board may include, for example, any one of a printed circuit board (PCB), a flexible printed circuit board (FPC), etc. For example, the pins of the first plug-in component 10 / the second plug-in component 20 may be PCB welded, for example, PCB pins. The printed circuit board may include welding holes, and the PCB pins of the first plug-in component 10 / the second plug-in component 20 are directly inserted into the welding holes of the printed circuit board, and the PCB pins of the pins and the welding holes of the printed circuit board are electrically connected by welding. The first plug-in component 10 / the second plug-in component 20 are welded on the printed circuit board, which can provide reliable electrical and mechanical connections and support efficient automated production. Optionally, the first plug-in component 10 / the second plug-in component 20 may also include fixing holes, and screws can be used to fix the first plug-in component 10 / the second plug-in component 20 to the printed circuit board to enhance stability.

[0298] Furthermore, the first plug component 10 / the second plug component 20 further includes a mounting plate for fixing and mounting the first plug component 10 / the second plug component 20. The mounting plate can effectively fix the first plug component 10 / the second plug component 20 and prevent the first plug component 10 / the second plug component 20 from loosening or shifting during use.

[0299] Continue as Figure 14 As shown, the power module 6 and the battery module 5 have metal housings. The metal housings can provide strong mechanical protection and effectively prevent the power module 6 and the battery module 5 from being physically damaged.

The first grounding component 36 and the second grounding component 16 are electrically connected at the same time; the first power component 35 and the second power component 15 are electrically connected at the same time; the first grounding component 36 is electrically connected earlier than the first power component 35. When the battery module 5 and the power module 6 are plugged in, the first grounding component 36 and the second grounding component 16 are electrically connected first, and then the first power component 35 and the second power component 15 are electrically connected. If the power module 6 fails and leakage occurs, the first grounding component 36 and the second grounding component 16 can conduct the current to the ground, reducing the risk of accidental injury.

The PCB soldering surface of the connector socket may include: fixing hole P1, pins P2, P3, P4, P5, and P6. Fixing hole P1 serves as a reinforcement, and screws can be passed through fixing hole P1 to secure the connector socket to the printed circuit board.

[0303] Figure 18 This is a structural diagram of the twelfth plug-in component provided in the embodiment of the present application. Figure 18 As shown, the conductive pins 11 on the mating surface of the connector socket may include: conductive pins Q2, Q3, Q4, Q5, and Q6. Conductive pin P2 corresponds to conductive pin Q2, conductive pin P3 corresponds to conductive pin Q3, conductive pin P4 corresponds to conductive pin Q4, conductive pin P5 corresponds to conductive pin Q5, and conductive pin P6 corresponds to conductive pin Q6. Pre-charge component 34 is conductive pin Q2; signal component 39 is conductive pin Q3; low-voltage power component 37 is conductive pin Q4; grounding component 36 is conductive pin Q5; and high-voltage power component 38 is conductive pin Q6.

[0310] It should be understood that Figure 18 The conductive pins Q2, Q3, Q4, Q5, and Q6 of the connector socket shown can each include multiple conductive pins to implement corresponding functions according to actual needs. The embodiment of the present application does not limit the number of conductive pins included in the conductive pins Q2, Q3, Q4, Q5, and Q6.

[0311] The embodiment of the present application further provides a power module 6 , which is equipped with the first plug-in component 10 and the second plug-in component 20 of the connector 1 . Figure 19 This is a schematic diagram of the structure of a power module provided in an embodiment of the present application. Figure 19 As shown, the power module 6 is installed with the first plug-in component 10 of the connector 1 and can be plugged with a module installed with the second plug-in component 20 of the connector 1 .

[0312] The embodiment of the present application also provides a battery module 5, which is equipped with the second plug-in component 20 / first plug-in component 10 of the connector 1. Figure 14 As shown, the battery module 5 includes a battery module 51 and a battery management module 52. The battery module 51 can be, for example, a module that can store and release electrical energy, such as a lithium-ion battery, a nickel-metal hydride battery, or a lead-acid battery. The battery management module 52 can be, for example, a module that monitors and manages the operating status of the battery module.

[0313] The battery module 51 is connected to the second low-voltage power component 17 of the second plug-in component 20, and the second low-voltage power component 17 is connected to the first low-voltage power component 37 of the first plug-in component 10. The battery module 51 outputs low-voltage electricity through the first low-voltage power component 37 and the second low-voltage power component 17. The battery management module 52 is connected to the second signal component 19 and the second high-voltage power component 18 of the second plug-in component 20; the second signal component 19 is connected to the first signal component 39 of the first plug-in component 10; and the second high-voltage power component 18 is connected to the first high-voltage power component 38 of the first plug-in component 10.

The battery management module 52 receives high-voltage electricity from the outside through the first high-voltage power component 38 and the second high-voltage power component 18.

[0314] Figure 20 This is a schematic diagram of the structure of the third battery pack provided in the embodiment of the present application. Figure 20 As shown, the battery pack 7 includes: a power module 6 and a battery module 5; the power module 6 and the battery module 5 are connected via a connector 1.

[0315] The battery pack 7 has a high-voltage power supply terminal 71 ; the high-voltage power supply terminal 71 is connected to the power module 6 / battery module 5 via a high-voltage busbar, and is used to output the voltage output by the power module 6 to the outside.

[0316] In one example, the power module 6 converts the low-voltage power input from the battery module 5 through the DC / DC converter 62 and outputs high-voltage power. The high-voltage output of the DC / DC converter 62 is output to the battery module 5 through the first high-voltage power component 38 and the second high-voltage power component 18 of the connector. The battery module 5 is then connected to the high-voltage busbar, which then outputs the high-voltage power through the high-voltage power supply terminal 71.

[0317] In another example, the power module 6 converts the low voltage power input from the battery module 5 into high voltage power through the DC / DC converter 62. The DC / DC converter 62 is connected to the high voltage bus, which outputs the high voltage power through the high voltage power supply terminal.

[0318] Figure 20 Take the example in which the high-voltage output end of the DC / DC converter 62 is output to the battery module 5 through the first high-voltage power component 38 and the second high-voltage power component 18 of the connector 1, the battery module 5 is connected to the high-voltage bus, and then the high-voltage bus outputs high-voltage electricity to the outside through the high-voltage power supply terminal 71.

[0319] Continue as Figure 20As shown, the battery module 5 includes a relay 53 connected between the high-voltage power supply terminal 71 and the high-voltage busbar. The relay 53 can be, for example, any device that turns on and off under the influence of current, such as an electromagnetic relay. The relay 53 can include, for example, a control module 54 and a switch module S1. The control module 54 can be, for example, a module that can generate a magnetic field, such as an electromagnetic coil. The switch module S1 can be, for example, any switch that turns on and off under the influence of a magnetic field, such as an armature. The relay 53 is controlled to turn on and off to enable / disable the high-voltage busbar to output high voltage electricity through the high-voltage power supply terminal 71.

[0320] The three-level first conductive component group 313 of the connector 1 includes a second safety detection component 40; the three-level second conductive component group 323 includes a first safety detection component 30. When the first plug-in component 10 and the second plug-in component 20 are plugged in, the first safety detection component 30 and the second safety detection component 40 form a power-on circuit to turn on the relay 53.

[0321] The first safety detection component 30 on the battery module 5 side includes a first safety detection sub-component 332 and a second safety detection sub-component 333. The control module 54 of the relay 53 is connected in series between the first and second safety detection sub-components 332 and 333. The switch module S1 of the relay 53 is connected in series between the high-voltage power supply terminal 71 and the high-voltage busbar. The switch module S1 of the relay 53 switches on or off depending on whether the control module 54 of the relay 53 is energized. The first and second safety detection sub-components 332 and 333 on the battery module 5 side form a power supply circuit for the control module 54 of the relay 53.

[0322] Second safety detection component 40 on power module 6 includes a third sub-safety detection component 334 and a fourth sub-safety detection component 335, which are electrically connected. Third sub-safety detection component 334 corresponds to first sub-safety detection component 332, and fourth sub-safety detection component 335 corresponds to second sub-safety detection component 333. The electrically connected third sub-safety detection component 334 and fourth sub-safety detection component 335 on power module 6 enable the power supply circuit of control module 54 of relay 53 to be connected when connector 1 is connected.

[0323] The battery module 5 further includes a power supply module 55 for the relay 53. The power supply module 55 can be any module that can provide voltage, such as the battery management module 52, the controller of the DC / DC converter 62, a voltage source, a current source, and the like.

[0324] In one example, the power supply module 55 is connected in series with the control module 54 . In another example, the power supply module 55 is connected in series between the third sub-safety detection component 334 and the fourth sub-safety detection component 335 .

[0325] Figure 20 For the purposes of this explanation, let's take the battery management module 52 as an example, representing the power supply module 55. One end of the control module 54 is electrically connected to the first safety detection component 332. The other end of the control module 54 is electrically connected to one end of the battery management module 52. The other end of the battery management module 52 is electrically connected to the second safety detection component 333. The third safety detection component 334 is electrically connected to the fourth safety detection component 335.

[0326] When the battery module 5 and the power module 6 are connected via connector 1, the first and third safety detection components 332 and 334 are electrically connected, the second and fourth safety detection components 333 and 335 are electrically connected, and the circuits between the control module 54 and the battery management module 52 are connected. The battery management module 52 sends a high-level signal to the control module 54, causing current to flow through the control module 54, generating a magnetic field that attracts the switch module S1 of the relay 53. This switches the switch S1 on, allowing the high-voltage power bus to output high-voltage power to the high-voltage power supply terminal 71. When the connector 1 between the battery module 5 and the power module 6 is disconnected, the first and third safety detection components 332 and 334 are electrically disconnected, and the second and fourth safety detection components 333 and 335 are electrically disconnected. The circuits between the control module 54 and the battery management module 52 are disconnected, and no current flows through the control module 54, thus no magnetic field is generated. The switch module S1 of the relay 53 is released, causing it to turn off, and the high-voltage power bus stops outputting high-voltage power to the high-voltage power supply terminal 71. Through the first safety detection component 30 and the second safety detection component 40, only when the connector 1 is connected, the relay 53 can be turned on under the control of the battery management module 52, and the battery pack 7 can provide power supply voltage to the outside; when the connector 1 is loose or the power module 6 is manually disassembled, the first safety detection component 30 and the second safety detection component 40 are disconnected before the low-voltage power component and the high-voltage power component, which can improve the safety of the battery pack 7 and prevent the operator from accidentally getting an electric shock.

[0327] Furthermore, the battery pack has a signal terminal 72 ; the signal terminal 72 is connected to the battery module 5 for transmitting a communication signal of the battery module 5 .

[0328] Figure 21 This is a schematic diagram of the structure of a battery system provided in an embodiment of the present application. Figure 21 As shown, the battery system includes N power modules 6, N battery modules 5, and a high-voltage box 8; wherein N is a positive integer.

[0329] The high-voltage box 8 may be, for example, any device capable of distributing and managing high-voltage electricity, such as a power distribution unit (PDU).

[0330] The power module 6 is connected to the corresponding battery module 5 via a first plug-in component 10 and a second plug-in component 20 ; the battery modules 5 are electrically connected in cascade; and the high-voltage box 8 is electrically connected to the last-stage battery pack 7 .

[0331] The battery module 5 has a high-voltage power supply terminal 71 ; the high-voltage power supply terminal 71 is connected to the power module 6 through the high-voltage bus, the first high-voltage power component 38 , and the second high-voltage power component 18 , and is used to output the voltage output by the power module 6 to the outside.

[0332] Continue as Figure 20 As shown, the battery module 5 includes a relay 53 connected between the high-voltage power supply terminal 71 and the high-voltage busbar. The relay 53 can be, for example, any device that turns on and off under the influence of current, such as an electromagnetic relay. The relay 53 can include, for example, a control module 54 and a switch module S1. The control module 54 can be, for example, a module that can generate a magnetic field, such as an electromagnetic coil. The switch module S1 can be, for example, any switch that turns on and off under the influence of a magnetic field, such as an armature. The relay 53 is controlled to turn on and off to enable / disable the high-voltage busbar to output high voltage electricity through the high-voltage power supply terminal 71.

[0333] The first conductive component 11 includes: a second safety detection component 40; the second conductive component 21 includes: a first safety detection component 30; when the first plug-in component 10 and the second plug-in component 20 are plugged in, the first safety detection component 30 and the second safety detection component 40 form a power-on circuit to turn on the relay 53.

[0334] The first safety detection component 30 and the second safety detection component 40 are electrically connected later than the first power component 35 and the second power component 15. If the connector 1 becomes loose or the power module 6 is manually disassembled, the first safety detection component 30 and the second safety detection component 40 are disconnected before the first power component 35 and the second power component 15, thereby improving the safety of the battery system and preventing operators from accidentally getting an electric shock.

[0335] The first safety detection component 30 includes: a first sub-safety detection component 332 and a second sub-safety detection component 333;

[0336] The control module 54 of the relay 53 is connected in series between the first and second safety detection sub-components 332 and 333. The switch module of the relay 53 is connected in series between the high-voltage power supply terminal 71 and the high-voltage busbar. The switch module S1 of the relay 53 switches on or off depending on whether the control module 54 of the relay 53 is energized. The first and second safety detection sub-components 332 and 333 form a power supply circuit for the control module 54 of the relay 53.

[0337] The second safety detection component 40 includes a third sub-safety detection component 334 and a fourth sub-safety detection component 335, which are electrically connected. The third sub-safety detection component 334 corresponds to the first sub-safety detection component 332, and the fourth sub-safety detection component 335 corresponds to the second sub-safety detection component 333.
