[0006] In some embodiments, the maximum contact area of ​​the first plug-in portion and the second plug-in portion when plugged in is S1, and in the third mating state, the first plug-in portion and the second plug-in portion are spaced apart.

[0007] In the above technical solution, the maximum contact area of ​​the first plug-in portion and the second plug-in portion is set to S1, and in the third mating state, the first plug-in portion and the second plug-in portion are spaced apart, so that the user can judge whether the electrical connector is in the fully plugged state, the intermediate state, or the fully disconnected state according to the electrical parameters of the part of the electronic component connected between the first connection portion and the second connection portion, so that the user can perform corresponding operations later.

[0008] In some embodiments, the electrical connector is a high voltage connector.

[0009] In the above technical solution, by setting the electrical connector as a high-voltage electrical connector, the user can judge the state of the high-voltage electrical connector based on the electrical parameters of the part of the electronic component connected between the first connection part and the second connection part, whether it is in good contact, poor contact or completely disconnected, thereby improving the practicality of the electrical connector.

[0010] In some embodiments, the electronic component is configured so that an electrical parameter of a portion of the electronic component connected between the first connection portion and the second connection portion changes as a contact area between the first plug-in portion and the second plug-in portion changes.

[0011] In the above technical solution, by setting the electronic component to be configured so that the electrical parameters of the part connected between the first connecting part and the second connecting part change with the contact area between the first plug-in part and the second plug-in part, the electrical parameters of the electronic component are different for different contact areas between the first plug-in part and the second plug-in part. In all the mating states between the first plug-in part and the second plug-in part, it is further convenient to judge which state of all the above mating states the electrical connector is in according to the electrical parameters of the part of the electronic component connected between the first connecting part and the second connecting part, thereby improving the accuracy of judging the mating state of the electrical connector.

[0012] In some embodiments, one of the first connection part and the second connection part is formed on a plug, and the other is formed on a socket, the electronic component includes a capacitor, the capacitor includes a first conductive plate and a second conductive plate arranged at intervals, the first conductive plate is fixed to the plug and electrically connected to one of the first connection part and the second connection part, and the second conductive plate is fixed to the socket and electrically connected to the other of the first connection part and the second connection part; or, the electronic component includes a variable resistor, the variable resistor is electrically connected between the first connection part and the second connection part, and the variable resistor is configured so that the resistance of the variable resistor changes with the change of the contact area between the first plug-in part and the second plug-in part.

[0013] In the above technical solution, by setting the electronic components including capacitors, the first conductive plate is electrically connected to one of the first connection part and the second connection part, and the second conductive plate is electrically connected to the other of the first connection part and the second connection part, so that the capacitance value of the capacitor can change with the change of the contact area between the first plug-in part and the second plug-in part, so that the current mating state of the electrical connection can be accurately determined by the capacitance value of the capacitor, so that the user can perform corresponding operations later; by setting the electronic components including variable resistors, the resistance value of the variable resistor changes with the change of the contact area between the first plug-in part and the second plug-in part, so that the current mating state of the electrical connector can be accurately determined by the resistance value of the variable resistor, so that the user can perform corresponding operations later.

[0014] In some embodiments, the first connection portion and the second connection portion are spaced apart and are both formed on one of the plug and the socket, the electronic components are disposed on the other of the plug and the socket, the electronic components include resistors, the resistors include a first resistor and a second resistor spaced apart, the first resistor and the second resistor are insulated from each other, in the second mating state, one of the first resistor and the second resistor is electrically connected between the first connection portion and the second connection portion; in the third mating state, the resistor is disconnected from the first connection portion and the second connection portion; in the first mating state, the first resistor and the second resistor are electrically connected in parallel between the first connection portion and the second connection portion; or, in the first mating state, the other of the first resistor and the second resistor is electrically connected between the first connection portion and the second connection portion, and the resistance values ​​of the first resistor and the second resistor are not equal.

[0015] In the above technical solution, by setting the electronic components including the first resistor and the second resistor arranged at intervals, and setting the first mating state, the second mating state and the third mating state, the first resistor and the second resistor are respectively connected between the first connecting part and the second connecting part in different forms, so that the state of the electrical connector can be accurately judged by the resistance value between the first connecting part and the second connecting part.

[0016] In some embodiments, the electrical connector also includes: a first spring clip and a second spring clip, the first spring clip is electrically connected to the first connecting portion, the second spring clip is electrically connected to the second connecting portion, in the first mating state and the second mating state, the resistor is electrically connected between the first spring clip and the second spring clip, and in the third mating state, the first spring clip and the second spring clip are electrically connected.

[0017] In the above technical solution, by setting the first spring sheet and the second spring sheet, in the third mating state, the first spring sheet and the second spring sheet are electrically connected, which will not affect the accuracy of judging the current state of the electrical connector by the resistance between the first connecting part and the second connecting part; moreover, the first connecting parts and the second connecting parts of multiple electrical connectors can also be connected in series to the same acquisition circuit, even if one or more of the electrical connectors are in the third mating state, the resistance of the entire acquisition circuit can still be collected by a collection device to judge which electrical connector or connectors are in the third mating state, and to judge which mating state the remaining electrical connectors are in, that is, it is convenient to judge the current state of all the electrical connectors on the acquisition circuit by a collection device, and the acquisition circuit will not be broken due to one or more electrical connectors being in the third mating state, so that the resistance of the acquisition circuit cannot be collected, thereby achieving accurate diagnosis of the state of all electrical connectors in the acquisition circuit and accurate fault location.

[0018] In some embodiments, at least one of the first spring sheet and the second spring sheet is cantilevered and has a fixed end and a free end, and at least one of the first spring sheet and the second spring sheet includes a first elastic segment extending in a direction from the fixed end to the free end and in a direction close to the other, and a second elastic segment extending in a direction from the fixed end to the free end and in a direction away from the other, so that a mating opening is formed between the first spring sheet and the second spring sheet at an end facing the electronic component, and the width of the mating opening decreases along the mating direction.

[0019] In the above technical solution, the mating opening can be defined by the second elastic section of at least one of the first spring sheet and the second spring sheet, and the mating opening can play a certain guiding role in the mating of the electronic components between the first spring sheet and the second spring sheet, thereby facilitating the mating of the electronic components with the first spring sheet and the second spring sheet; at the same time, as the contact area between the first mating portion and the second mating portion increases, the electronic components can extend to the position corresponding to the first elastic section. Since the first elastic section extends in a direction away from the other spring sheet, the first spring sheet and the second spring sheet can provide sufficient accommodating space for the electronic components at the position corresponding to the first elastic section, thereby facilitating providing a suitable mating depth for the electronic components.

[0020] In some embodiments, the first resistor is disposed on a side of the second resistor facing the first elastic sheet and the second elastic sheet, and in a width direction of the mating port, a width of the first resistor is smaller than a width of the second resistor.

[0021] In the above technical solution, by arranging the first resistor on the side of the second resistor facing the first spring sheet and the second spring sheet, the first resistor is electrically connected to the first spring sheet and the second spring sheet before the second resistor; combined with the fact that the width of the first resistor is smaller than the width of the second resistor, it is beneficial to improve the convenience of plugging and matching the electronic components with the first spring sheet and the second spring sheet, so that the electronic components can be more smoothly plugged and matched between the first spring sheet and the second spring sheet.

[0022] In some embodiments, one end of the electronic component facing the first elastic sheet and the second elastic sheet has a mating portion, and in the width direction of the mating opening, the width of the mating portion decreases along the mating direction.

[0023] In the above technical solution, by providing a mating portion at one end of the electronic component facing the first spring sheet and the second spring sheet, and reducing the width of the mating portion along the mating direction, the mating portion can play a certain guiding role in the mating of the electronic component between the first spring sheet and the second spring sheet, thereby facilitating the mating of the electronic component and the first spring sheet and the second spring sheet.

[0024] In some embodiments, at least one of the first elastic sheet and the second elastic sheet is formed into an arc-shaped structure.

[0025] In the above technical solution, by arranging at least one of the first spring sheet and the second spring sheet to form an arc-shaped structure, the structure of the corresponding spring sheet can be simplified, and the convenience of plugging and matching the electronic components can be improved.

[0026] In a second aspect, an embodiment of the present application provides a high-voltage electrical connection system, comprising the above-mentioned electrical connector, a collection circuit and a collection device, wherein the electronic components are connected to the collection circuit via a first connection portion and a second connection portion, and the collection device is used to collect electrical parameters of the portion of the electronic components connected between the first connection portion and the second connection portion.

[0027] In the above technical solution, since the high-voltage electrical connection system adopts the above-mentioned electrical connector, the safety of the high-voltage electrical connection system can be improved, making it easier for users to respond and handle in a timely manner.

[0028] In some embodiments, there are multiple electrical connectors, each of which is the above-mentioned electrical connector and includes a first spring clip and a second spring clip, and parts of multiple electronic components connected between the first connecting part and the second connecting part are respectively connected in series to the acquisition circuit, and each electronic component is a resistance structure. The acquisition device is used to collect the total resistance of the multiple resistance structures connected in series to the acquisition circuit.

[0029] In the above technical solution, by connecting the first connecting parts and the second connecting parts of multiple electrical connectors in series to the same acquisition circuit, even if one or more of the electrical connectors are in the third mating state, the acquisition circuit still maintains a connection state, and a collection device can still be used to collect the resistance of the entire acquisition circuit to determine which electrical connector or connectors are in the third mating state and to determine which mating state the remaining electrical connectors are in. The collection device collects the sum of the resistances of the multiple electrical connectors connected to the acquisition circuit; if the resistance structure configured for each electrical connector can form a different combination of resistance values, it is convenient to use a collection device to determine the current state of all electrical connectors on the acquisition circuit, and the acquisition circuit will not be disconnected due to one or more electrical connectors being in the third mating state, making it impossible to collect the resistance of the acquisition circuit, thereby achieving accurate diagnosis of the state of all electrical connectors in the acquisition circuit and accurate fault location.

[0030] In a third aspect, an embodiment of the present application provides an electrical device, comprising the above-mentioned high-voltage electrical connection system.

[0031] In the above technical solution, since the electrical device adopts the above high-voltage electrical connection system, the safety of the electrical device can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In recent years, new energy vehicles have developed by leaps and bounds. In the field of electric vehicles, batteries, as the power source of electric vehicles, play an irreplaceable and important role. Among them, there are many high-voltage electrical devices in pure electric vehicles, and each high-voltage device needs to be connected to other high-voltage electrical devices through high-voltage connecting devices. Therefore, accurately knowing the connection status of the high-voltage connector plays an important role in whether the electrical connection system can operate normally.

[0049] Based on the above considerations, in order to improve the safety performance of the electrical connection system, an electrical connector is proposed, wherein the electrical connector has a first connection portion and a second connection portion, and the electrical connector includes a plug, a socket and an electronic component, wherein the plug has a first plug-in portion, the socket has a second plug-in portion, the second plug-in portion is suitable for plugging and mating with the first plug-in portion, the electronic component is arranged between the plug and the socket, and is electrically connected to the first connection portion and the second connection portion, respectively, the electrical connector has a first mating state, a second mating state and a third mating state, in the first mating state, the contact area between the first plug-in portion and the second plug-in portion is S1, in the second mating state, the contact area between the first plug-in portion and the second plug-in portion is S2. In the first mating state, the contact area between the first plug-in portion and the second plug-in portion is S2, and the contact area between the first plug-in portion and the second plug-in portion in the third mating state is S3, S1>S2>S3, and the electronic component is configured so that in the first mating state, the electrical parameter of the part of the electronic component connecting the first connection part and the second connection part is X1, in the second mating state, the electrical parameter of the part of the electronic component connecting the first connection part and the second connection part is X2, and in the third mating state, the electrical parameter of the part of the electronic component connecting the first connection part and the second connection part is X3, and any two of X1, X2 and X3 are not equal.

[0050] In the above technical solution, an electronic component is arranged between the plug and the socket, and the electronic component is configured so that in the first mating state, the electrical parameter of the part of the electronic component connecting the first connection part and the second connection part is X1, in the second mating state, the electrical parameter of the part of the electronic component connecting the first connection part and the second connection part is X2, and in the third mating state, the electrical parameter of the part of the electronic component connecting the first connection part and the second connection part is X3, and any two of X1, X2 and X3 are not equal, so as to realize timely detection of at least three mating states of the electrical connector, so as to realize interlocking indication of the electrical connector 100, facilitate users to make corresponding processing according to the mating state of the electrical connector, and improve the safety of the electrical connection system.

[0051] The embodiment of the present application provides an electric device using the high-voltage electric connection system disclosed herein, and the electric device may be, but is not limited to, an electric tool, a battery vehicle, an electric vehicle, a ship, a spacecraft, etc. Among them, the spacecraft may include an airplane, a rocket, a space shuttle, a spacecraft, etc., and the electric tool may include a metal cutting electric tool, a grinding electric tool, an assembly electric tool, and a railway electric tool, such as an electric drill, an electric grinder, an electric wrench, an electric screwdriver, an electric hammer, an impact drill, a concrete vibrator, an electric planer, etc.

[0052] For the convenience of explanation, the following embodiments take the electrical device 1000 as a vehicle as an example, and introduce the structures of the electrical device 1000, the high-voltage electrical connection system and the electrical connector of the present application in detail.

[0053] Please refer to Figure 1 , Figure 1 The power consumption device 1000 provided in some embodiments of the present application is a schematic diagram of the structure of a vehicle. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle.

[0054] Please refer to Figure 2 , Figure 2 A schematic diagram of a high-voltage electrical connection system 200 provided in some embodiments of the present application. The high-voltage electrical connection system 200 may include one electrical connector 100 or multiple electrical connectors 100 .

[0055] Please refer to Figure 3-Figure 7 , Figure 3 This is a schematic diagram of the structure of an electrical connector 100 provided in some embodiments of the present application. Figure 4 The schematic diagram of the structure of the electrical connector 100 provided in some other embodiments of the present application is as follows: Figure 5-Figure 7 The schematic diagram of the structure of the electrical connector 100 provided in some embodiments of the present application. The electrical connector 100 can have a fully plugged state, a fully disconnected state, and an intermediate state between the fully plugged state and the fully disconnected state.

[0056] Please refer to Figure 3-Figure 7In the embodiment of the present application, the electrical connector 100 includes a plug 1 and a socket 2. The plug 1 has a first plug-in portion 11, and the socket 2 has a second plug-in portion 21. The second plug-in portion 21 is adapted to be plugged in and matched with the first plug-in portion 11, so that the electrical connector 100 switches from a fully disconnected state to a fully plugged state or to an intermediate state. It can be seen that when the electrical connector 100 is in a fully plugged state, the second plug-in portion 21 is fully plugged in with the first plug-in portion 11. At this time, the second plug-in portion 21 is in good contact with the first plug-in portion 11, and the electrical connector 100 is well connected. At this time, the electrical connection system can be operated accordingly according to the needs. For example, when the electrical connector 100 is used in a vehicle, the vehicle is in good condition and can be driven or charged at full power. When the electrical connector 100 is in a fully disconnected state, the second plug-in portion 21 is disengaged from the first plug-in portion 11. At this time, the second plug-in portion 21 is not in contact with the first plug-in portion 11, and the two are separated. The electrical connector 100 is disconnected. At this time, for safety reasons, especially for high-voltage systems, it should be prohibited to connect. When the electrical connector 100 is in the intermediate state, the second plug-in portion 21 is partially mated with the first plug-in portion 11. At this time, the second plug-in portion 21 has poor contact with the first plug-in portion 11, and the electrical connector 100 is poorly connected. The contact resistance of the electrical connector 100 is large, and the contact portion between the first plug-in portion 11 and the second plug-in portion 21 (i.e., the connection point of the electrical connector 100) is prone to overheating. If there is an emergency need at this time, power-on may be allowed but the power may be limited. For example, when the electrical connector 100 is used in a vehicle, if the user does have an emergency driving or charging need, the vehicle may be allowed to be powered on but the power may be limited for limp driving or charging. At the same time, a warning reminder may be issued to remind the user to perform maintenance.

[0057] Obviously, the contact area between the first plug part 11 and the second plug part 21 in the fully plugged state is greater than the contact area between the first plug part 11 and the second plug part 21 in the intermediate state and greater than the contact area between the first plug part 11 and the second plug part 21 in the fully disconnected state.

[0058] The electrical connector 100 has a first mating state, a second mating state and a third mating state. In the first mating state, the contact area between the first plug-in portion 11 and the second plug-in portion 21 is S1; in the second mating state, the contact area between the first plug-in portion 11 and the second plug-in portion 21 is S2; in the third mating state, the contact area between the first plug-in portion 11 and the second plug-in portion 21 is S3. Among them, S1>S2>S3.

[0059] Exemplarily, the first mating state can be a fully plugged in state, the second mating state is an intermediate state, and the third mating state is a fully disconnected state; or, the first mating state is a fully plugged in state, and the second mating state and the third mating state are both intermediate states; or, the first mating state and the second mating state are both intermediate states, and the third mating state is a fully disconnected state; or, the first mating state, the second mating state, and the third mating state are all intermediate states.

[0060] The electrical connector 100 has a first connection part 100a and a second connection part 100b. The electrical connector 100 also includes an electronic component 3. The electronic component 3 is arranged between the plug 1 and the socket 2, and the electronic component 3 is electrically connected to the first connection part 100a and the second connection part 100b respectively, that is, the electronic component 3 is electrically connected to the first connection part 100a, and the electronic component 3 is also electrically connected to the second connection part 100b.

[0061] Among them, the electronic component 3 is configured as follows: in the first mating state, the electrical parameters of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b (for example, the resistance, capacitance, etc. of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b) are X1, in the second mating state, the electrical parameters of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b are X2, and in the third mating state, the electrical parameters of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b are X3, and any two of X1, X2 and X3 are not equal.

[0062] Therefore, when the electrical connector 100 is in use, the first connection part 100a and the second connection part 100b can be connected to the acquisition circuit 101, so that the electrical parameters of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b can be collected by the acquisition device 102, so as to judge the contact area between the first plug-in part 11 and the second plug-in part 21 in the current state according to the acquisition result, and then obtain the current mating state of the electrical connector 100, so that the user can judge whether the current mating state of the electrical connector 100 is adapted to the use requirements, and it is convenient for the user to determine the subsequent corresponding execution operation according to the current mating state of the electrical connector 100; for example, if the current mating state of the electrical connector 100 cannot adapt to the use requirements, the relative position of the plug 1 and the socket 2 can be continuously adjusted to change the contact area between the first plug-in part 11 and the second plug-in part 21 until the use requirements are met, or if the current mating state of the electrical connector 100 should not allow the first operation to be performed, but can allow the second operation to be performed, the second operation is different from the first operation, and the subsequent operation can be restricted to remind the user of the subsequent operation, etc.

[0063] In addition, the electrical connector 100 of the embodiment of the present application can facilitate the user to determine at least three different mating states of the electrical connector 100.

[0064] Exemplarily, when the electrical parameter of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b is collected as X1, it can be judged that the electrical connector 100 is in the first mating state, and the contact area between the first plug-in part 11 and the second plug-in part 21 is S1; when the electrical parameter of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b is collected as X2, it can be judged that the electrical connector 100 is in the second mating state, and the contact area between the first plug-in part 11 and the second plug-in part 21 is S2; when the electrical parameter of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b is collected as X3, it can be judged that the electrical connector 100 is in the third mating state, and the contact area between the first plug-in part 11 and the second plug-in part 21 is S3.

[0065] In the above technical solution, an electronic component 3 is arranged between the plug 1 and the socket 2, and the electronic component 3 is configured such that the electrical parameter of the part of the electronic component 3 connecting the first connection part 100a and the second connection part 100b in the first mating state is X1, the electrical parameter of the part of the electronic component 3 connecting the first connection part 100a and the second connection part 100b in the second mating state is X2, and the electrical parameter of the part of the electronic component 3 connecting the first connection part 100a and the second connection part 100b in the third mating state is X3, and any two of X1, X2 and X3 are not equal, so as to realize timely detection of at least three mating states of the electrical connector 100, so as to realize interlocking indication of the electrical connector 100, facilitate users to make corresponding processing according to the mating state of the electrical connector 100, and improve the safety of the electrical connection system.

[0066] In the embodiment of the present application, the plug 1 and the socket 2 are plugged together through the first plug-in portion 11 and the second plug-in portion 21, and the plug 1 can move in a direction close to the socket 2 until it is plugged with the socket 2, or it can be disengaged from the socket 2 in a direction away from the socket 2. In the following description of the present application, the example that the plug 1 can move relative to the socket 2 along the plugging direction of the first plug-in portion 11 and the second plug-in portion 21 is used for explanation, and those skilled in the art can easily understand other movement modes of the plug 1 relative to the socket 2 after reading the following technical solutions; moreover, the driving force for the movement of the plug 1 relative to the socket 2 is not limited to manual, and the movement of the plug 1 relative to the socket 2 can also be achieved by an electric drive device, etc.

[0067] In some embodiments of the present application, the maximum contact area of ​​the first plug-in portion 11 and the second plug-in portion 21 is S1, and in the third mating state, the first plug-in portion 11 and the second plug-in portion 21 are spaced apart, at which time the first plug-in portion 11 and the second plug-in portion 21 are disengaged, S3=0.

[0068] It can be seen that in the above technical solution, the first mating state is a fully plugged-in state, the second mating state is an intermediate state, and the third mating state is a fully disconnected state.

[0069] In the above technical solution, the maximum contact area of ​​the first plug-in portion 11 and the second plug-in portion 21 is set to S1, and in the third mating state, the first plug-in portion 11 and the second plug-in portion 21 are spaced apart, so that the user can judge whether the electrical connector 100 is in the fully plugged state, the intermediate state, or the fully disconnected state according to the electrical parameters of the portion of the electronic component 3 connected between the first connection portion 100a and the second connection portion 100b, so that the user can perform corresponding operations later.

[0070] Exemplarily, when the electrical parameter of the portion of the electronic component 3 connected between the first connection part 100a and the second connection part 100b is collected as X1, it can be determined that the electrical connector 100 is in a fully plugged state; when the electrical parameter of the portion of the electronic component 3 connected between the first connection part 100a and the second connection part 100b is collected as X2, it can be determined that the electrical connector 100 is in an intermediate state; when the electrical parameter of the portion of the electronic component 3 connected between the first connection part 100a and the second connection part 100b is collected as X3, it can be determined that the electrical connector 100 is in a completely disconnected state.

[0071] In some embodiments of the present application, the electrical connector 100 is a high voltage electrical connector.

[0072] In the above technical solution, by setting the electrical connector 100 as a high-voltage electrical connector, the user can judge the state of the high-voltage electrical connector based on the electrical parameters of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b, whether it is in good contact, poor contact or completely disconnected, thereby improving the practicality of the electrical connector 100.

[0073] In some embodiments of the present application, the electronic component 3 is configured such that the electrical parameters of the portion of the electronic component 3 connected between the first connecting portion 100a and the second connecting portion 100b change as the contact area between the first plug-in portion 11 and the second plug-in portion 21 changes. That is, if the contact area between the first plug-in portion 11 and the second plug-in portion 21 changes, the electrical parameters of the electronic component 3 also change accordingly.

[0074] In the above technical solution, the electrical parameters of the portion of the electronic component 3 configured to be connected between the first connection portion 100a and the second connection portion 100b are changed as the contact area between the first plug portion 11 and the second plug portion 21 changes. For different contact areas between the first plug portion 11 and the second plug portion 21, the electrical parameters of the electronic component 3 are also different. In all the mating states between the first plug portion 11 and the second plug portion 21, it is further convenient to judge which state of all the mating states the electrical connector 100 is in according to the electrical parameters of the portion of the electronic component 3 connected between the first connection portion 100a and the second connection portion 100b, thereby improving the accuracy of judging the mating state of the electrical connector 100. For example, it is possible to judge the ratio of the contact area between the first plug portion 11 and the second plug portion 21 to the maximum contact area in the current state of the electrical connector 100.

[0075] Exemplarily, the electronic component 3 is configured such that the contact area S between the first plug-in portion 11 and the second plug-in portion 21 and the electrical parameter X of the portion of the electronic component 3 connected between the first connection portion 100a and the second connection portion 100b satisfy a functional relationship: S=f(X). For example, the electronic component 3 is configured such that the electrical parameter of the portion of the electronic component 3 connected between the first connection portion 100a and the second connection portion 100b increases as the contact area between the first plug-in portion 11 and the second plug-in portion 21 increases; for another example, the electronic component 3 is configured such that the electrical parameter of the portion of the electronic component 3 connected between the first connection portion 100a and the second connection portion 100b decreases as the contact area between the first plug-in portion 11 and the second plug-in portion 21 increases.

[0076] Please refer to Figure 3 In some embodiments of the present application, one of the first connection part 100a and the second connection part 100b is formed on the plug 1, and the other of the first connection part 100a and the second connection part 100b is formed on the socket 2, then the first connection part 100a is formed on the plug 1 and the second connection part 100b is formed on the socket 2, or the first connection part 100a is formed on the socket 2 and the second connection part 100b is formed on the plug 1; the electronic component 3 includes a capacitor 31, the capacitor 31 includes a first conductive electrode plate 311 and a second conductive electrode plate 312 arranged at intervals, the first conductive electrode plate 311 is fixedly provided on the plug 1, and the first conductive electrode plate 311 is electrically connected to the above one of the first connection part 100a and the second connection part 100b, the second conductive electrode plate 312 is fixedly provided on the socket 2, and the second conductive electrode plate 312 is electrically connected to the above other of the first connection part 100a and the second connection part 100b.

[0077] It can be seen that in the above technical solution, when the plug 1 moves relative to the socket 2, the distance d between the first conductive electrode plate 311 and the second conductive electrode plate 312 can be changed, thereby changing the capacitance value of the capacitor 31. The capacitance value of the capacitor 31 can change with the change in the degree of fit between the first plug-in portion 11 and the second plug-in portion 21.

[0078] In the above technical solution, the electronic component 3 includes a capacitor 31, the first conductive electrode plate 311 is electrically connected to one of the first connection part 100a and the second connection part 100b, and the second conductive electrode plate 312 is electrically connected to the other of the first connection part 100a and the second connection part 100b, so that the capacitance value of the capacitor 31 can change with the change of the contact area between the first plug-in part 11 and the second plug-in part 21, so that the current mating state of the electrical connector 100 can be accurately judged by the capacitance value of the capacitor 31, so that the user can perform corresponding operations later.

[0079] Exemplarily, when the plug 1 moves relative to the socket 2 along the plugging direction of the first plug part 11 and the second plug part 21, when the plug 1 approaches the socket 2 so that the distance between the plug 1 and the socket 2 is reduced, the contact area between the first plug part 11 and the second plug part 21 can be increased, and the spacing between the first conductive electrode plate 311 and the second conductive electrode plate 312 is reduced, and the capacitance value of the capacitor 31 is increased; and when the plug 1 moves away from the socket 2 so that the distance between the plug 1 and the socket 2 is increased, the contact area between the first plug part 11 and the second plug part 21 can be reduced, and the spacing between the first conductive electrode plate 311 and the second conductive electrode plate 312 is increased, and the capacitance value of the capacitor 31 is reduced. It can be seen that the capacitance value of the capacitor 31 can change with the change of the contact area between the first plug part 11 and the second plug part 21, and there is a certain functional relationship between the contact area between the first plug part 11 and the second plug part 21 and the capacitance value of the capacitor 31, so that the current contact area between the first plug part 11 and the second plug part 21 can be indirectly obtained according to the capacitance value of the capacitor 31.

[0080] Please refer to Figure 4In some embodiments of the present application, one of the first connection part 100a and the second connection part 100b is formed on the plug 1, and the other of the first connection part 100a and the second connection part 100b is formed on the socket 2, then the first connection part 100a is formed on the plug 1, and the second connection part 100b is formed on the socket 2, or the first connection part 100a is formed on the socket 2, and the second connection part 100b is formed on the plug 1; the electronic component 3 includes a variable resistor 32, the variable resistor 32 is electrically connected between the first connection part 100a and the second connection part 100b, and the variable resistor 32 is configured such that the resistance value of the variable resistor 32 changes with the change of the contact area between the first plug part 11 and the second plug part 21. Among them, the variable resistor 32 is a resistor 33 whose resistance value can be adjusted.

[0081] It can be seen that in the above technical solution, the resistance value of the variable resistor 32 can be changed when the plug 1 moves relative to the socket 2, and the resistance value of the variable resistor 32 can change with the change of the matching degree between the first plug-in portion 11 and the second plug-in portion 21.

[0082] In the above technical solution, the electronic component 3 includes a variable resistor 32, and the resistance of the variable resistor 32 changes with the change of the contact area between the first plug-in portion 11 and the second plug-in portion 21, so that the current mating state of the electrical connector 100 can be accurately determined by the resistance of the variable resistor 32, so that the user can perform corresponding operations later.

[0083] Exemplarily, the variable resistor 32 is a sliding rheostat, which includes a terminal, a slider and a spirally wound resistance wire, one of the first connection part 100a and the second connection part 100b is electrically connected to the terminal, and the other of the first connection part 100a and the second connection part 100b is electrically connected to the slider; the following is an example in which the first connection part 100a is formed on the plug 1 and the second connection part 100b is formed on the socket 2: the first connection part 100a is electrically connected to the terminal, the second connection part 100b is electrically connected to the slider, and the plug 1 moves relative to the socket 2 along the plugging direction of the first plug-in part 11 and the second plug-in part 21, so that the slider can slide relative to the resistance wire to change the connection of the resistance wire to the first connection part 100a and the second connection part 100b The length between them changes the resistance value of the portion of the resistance wire connected to the first connection part 100a and the second connection part 100b; when the plug 1 is close to the socket 2 so that the distance between the plug 1 and the socket 2 is reduced, the contact area between the first plug-in portion 11 and the second plug-in portion 21 can be increased, and the spacing between the terminal and the slide is reduced, then the resistance value of the portion of the resistance wire connected to the first connection part 100a and the second connection part 100b is reduced; and when the plug 1 is away from the socket 2 so that the distance between the plug 1 and the socket 2 is increased, the contact area between the first plug-in portion 11 and the second plug-in portion 21 can be reduced, and the spacing between the terminal and the slide is increased, then the resistance value of the portion of the resistance wire connected to the first connection part 100a and the second connection part 100b is increased. It can be seen that the resistance of the part of the sliding rheostat that contacts the first connecting part 100a and the second connecting part 100b can change with the change of the contact area between the first plug-in part 11 and the second plug-in part 21. There is a certain functional relationship between the contact area between the first plug-in part 11 and the second plug-in part 21 and the above resistance, so that the current contact area between the first plug-in part 11 and the second plug-in part 21 can be indirectly obtained according to the resistance between the electronic component 3 connected to the first connecting part 100a and the second connecting part 100b.

[0084] Please refer to Figure 5-Figure 7 In some embodiments of the present application, the first connection portion 100a and the second connection portion 100b are arranged at intervals and the first connection portion 100a and the second connection portion 100b are both formed on one of the plug 1 and the socket 2, and the electronic component 3 is arranged on the other of the plug 1 and the socket 2. Then the first connection portion 100a and the second connection portion 100b are both formed on the plug 1 and the electronic component 3 is arranged on the socket 2, or the first connection portion 100a and the second connection portion 100b are both formed on the socket 2 and the electronic component 3 is arranged on the plug 1; the electronic component 3 includes a resistor 33, and the resistor 33 includes a first resistor 331 and a second resistor 332 arranged at intervals, and the first resistor 331 and the second resistor 332 are insulated from each other.

[0085] Among them, in the second mating state, one of the first resistor 331 and the second resistor 332 is electrically connected between the first connection part 100a and the second connection part 100b (for the other of the first resistor 331 and the second resistor 332, it is electrically insulated from the first connection part 100a and / or the second connection part 100b). At this time, it can be judged that the electrical connector 100 is in the second mating state based on the collected resistance value between the first connection part 100a and the second connection part 100b being equal to the resistance value of one of the first resistor 331 and the second resistor 332.

[0086] In the third mating state, the resistor 33 is disconnected from the first connection part 100a and the second connection part 100b, and the first resistor 331 and the second resistor 332 are not connected between the first connection part 100a and the second connection part 100b. At this time, it can be judged that the electrical connector 100 is in the third mating state based on the collected resistance value between the first connection part 100a and the second connection part 100b being equal to infinity or 0 (for example, a spring sheet is provided between the first connection part 100a and the second connection part 100b as described below).

[0087] In the first mating state, the first resistor 331 and the second resistor 332 are electrically connected in parallel between the first connection part 100a and the second connection part 100b. At this time, the electrical connector 100 can be judged to be in the first mating state based on the collected resistance between the first connection part 100a and the second connection part 100b being equal to the resistance of the first resistor 331 and the second resistor 332 being connected in parallel; or, in the first mating state, the other of the first resistor 331 and the second resistor 332 is electrically connected between the first connection part 100a and the second connection part 100b (for the above one of the first resistor 331 and the second resistor 332, it is electrically insulated from the first connection part 100a and / or the second connection part 100b), and the resistance value of the first resistor 331 and the resistance value of the second resistor 332 are not equal. At this time, the electrical connector 100 can be judged to be in the first mating state based on the collected resistance between the first connection part 100a and the second connection part 100b being equal to the resistance value of the above other of the first resistor 331 and the second resistor 332, so as to distinguish it from the second mating state. It can be seen that the two implementations of the first mating state can both adapt to the second mating state and the third mating state described above, so as to use the resistance between the first connecting portion 100a and the second connecting portion 100b to determine the state of the electrical connector 100.

[0088] In the above technical solution, the electronic component 3 includes a first resistor 331 and a second resistor 332 that are spaced apart, and a first mating state, a second mating state and a third mating state are set. The first resistor 331 and the second resistor 332 are respectively connected between the first connection part 100a and the second connection part 100b in different forms, so that the state of the electrical connector 100 can be accurately judged by the resistance value between the first connection part 100a and the second connection part 100b.

[0089] Optionally, the first resistor 331 and the second resistor 332 may both be made of a high resistance material.

[0090] Please refer to Figure 5-Figure 7 In some embodiments of the present application, the electrical connector 100 further includes a first spring clip 41 and a second spring clip 42, wherein the first spring clip 41 is electrically connected to the first connection portion 100a, and the second spring clip 42 is electrically connected to the second connection portion 100b. In the first mating state and the second mating state, the resistor 33 is electrically connected between the first spring clip 41 and the second spring clip 42, that is, the first spring clip 41 is indirectly electrically connected to the second spring clip 42 through the resistor 33; in the third mating state, the first spring clip 41 and the second spring clip 42 are electrically connected, that is, the first spring clip 41 and the second spring clip 42 are directly in contact and electrically connected.

[0091] It can be understood that the resistance of the first spring piece 41 and the second spring piece 42 is significantly smaller than the resistance of the first resistor 331 and the second resistor 332. For example, the resistance of the first spring piece 41 and the second spring piece 42 is negligible relative to the resistance of the first resistor 331 and the second resistor 332. For example, the resistance of the first spring piece 41 and the second spring piece 42 is approximately 0. In the third matching state, the resistance between the first connection part 100a and the second connection part 100b is substantially 0. Of course, the first spring piece 41 and the second spring piece 42 may also have a certain smaller resistance.

[0092] In the above technical solution, by providing the first spring piece 41 and the second spring piece 42, in the third mating state, the first spring piece 41 and the second spring piece 42 are electrically connected, which will not affect the accuracy of judging the current state of the electrical connector 100 by the resistance between the first connecting portion 100a and the second connecting portion 100b; moreover, the first connecting portions 100a and the second connecting portions 100b of multiple electrical connectors 100 can be connected in series to the same collection circuit 101, even if one or more of the electrical connectors 100 are in the third mating state, the entire electrical connector 100 can still be collected by one collection device 102. The resistance of the acquisition loop 101 is used to determine which electrical connectors 100 are in the third mating state and to determine which mating state the remaining electrical connectors 100 are in. In other words, it is convenient to determine the current states of all electrical connectors 100 on the acquisition loop 101 through a collection device 102, and the acquisition loop 101 will not be broken due to one or more electrical connectors 100 being in the third mating state, making it impossible to collect the resistance value of the acquisition loop 101. This can achieve accurate diagnosis of the states of all electrical connectors 100 in the acquisition loop 101 and accurate fault location.

[0093] Optionally, at least one of the first elastic sheet 41 and the second elastic sheet 42 is a copper sheet or a copper substrate structure.

[0094] Please refer to Figure 5-Figure 7 In some embodiments of the present application, at least one of the first spring clip 41 and the second spring clip 42 is cantilevered, and at least one of the first spring clip 41 and the second spring clip 42 has a fixed end and a free end; if the first spring clip 41 has a fixed end and a free end, the fixed end of the first spring clip 41 can be electrically connected to the first connecting portion 100a, and if the second spring clip 42 has a fixed end and a free end, the fixed end of the second spring clip 42 can be electrically connected to the second connecting portion 100b.

[0095] Among them, at least one of the first spring piece 41 and the second spring piece 42 includes a first elastic segment 40a and a second elastic segment 40b. In the direction from the fixed end to the free end, the first elastic segment 40a extends in a direction toward the other, and the second elastic segment 40b extends in a direction away from the other, so that a mating port 40 is formed between the first spring piece 41 and the second spring piece 42 at the end facing the electronic component 3, and the width t of the mating port 40 decreases along the mating direction.

[0096] Obviously, when the first elastic sheet 41 includes the first elastic segment 40a and the second elastic segment 40b, in the direction from the fixed end of the first elastic sheet 41 to the free end of the first elastic sheet 41, the first elastic segment 40a of the first elastic sheet 41 extends in the direction toward the second elastic sheet 42, and the second elastic segment 40b of the first elastic sheet 41 extends in the direction away from the second elastic sheet 42; and / or, when the first elastic sheet 41 includes the first elastic segment 40a and the second elastic segment 40b, in the direction from the fixed end of the second elastic sheet 42 to the free end of the second elastic sheet 42, the first elastic segment 40a of the second elastic sheet 42 extends in the direction toward the first elastic sheet 41, and the second elastic segment 40b of the second elastic sheet 42 extends in the direction away from the first elastic sheet 41.

[0097] It can be seen that in the above technical solution, the mating port 40 can be defined by the second elastic segment 40b of at least one of the first spring sheet 41 and the second spring sheet 42, and the mating port 40 can play a certain guiding role in the mating of the electronic component 3 between the first spring sheet 41 and the second spring sheet 42, so as to facilitate the mating of the electronic component 3 and the first spring sheet 41 and the second spring sheet 42; at the same time, as the contact area between the first mating portion 11 and the second mating portion 21 increases, the electronic component 3 can extend to the position corresponding to the first elastic segment 40a. Since the first elastic segment 40a extends in a direction away from the other spring sheet, the first spring sheet 41 and the second spring sheet 42 can provide sufficient accommodating space for the electronic component 3 at the position corresponding to the first elastic segment 40a, so as to provide a suitable mating depth for the electronic component 3.

[0098] Please refer to Figure 5-Figure 7 In some embodiments of the present application, the first resistor 331 is arranged on the side of the second resistor 332 facing the first spring sheet 41 and the second spring sheet 42. In the width direction of the mating port 40, the width of the first resistor 331 is smaller than the width of the second resistor 332. Then, in the process of the first mating portion 11 being mated with the second mating portion 21, the first resistor 331 is electrically connected to the first spring sheet 41 and the second spring sheet 42 before the second resistor 332. The electrical connector 100 can be configured such that, in the second mating state, the first resistor 331 is electrically connected between the first connection portion 100a and the second connection portion 100b, and the second resistor 332 is electrically disconnected from the first connection portion 100a and the second connection portion 100b.

[0099] Among them, in the first mating state, the first resistor 331 and the second resistor 332 can be electrically connected in parallel between the first connection part 100a and the second connection part 100b; or, in the first mating state, the second resistor 332 is electrically connected between the first connection part 100a and the second connection part 100b, and the first resistor 331 is disconnected from the electrical connection with the first connection part 100a and the second connection part 100b.

[0100] In the above technical solution, by arranging the first resistor 331 on the side of the second resistor 332 facing the first spring clip 41 and the second spring clip 42, the first resistor 331 is electrically connected to the first spring clip 41 and the second spring clip 42 before the second resistor 332; combined with the fact that the width of the first resistor 331 is smaller than the width of the second resistor 332, it is beneficial to improve the convenience of plugging and matching the electronic component 3 with the first spring clip 41 and the second spring clip 42, so that the electronic component 3 can be more smoothly plugged between the first spring clip 41 and the second spring clip 42.

[0101] Please refer to Figure 5-Figure 7 In some embodiments of the present application, the electronic component 3 has a mating portion 30 at one end facing the first spring piece 41 and the second spring piece 42 , and the width of the mating portion 30 decreases along the mating direction in the width direction of the mating opening 40 .

[0102] In the above technical solution, by providing a mating portion 30 at one end of the electronic component 3 facing the first spring piece 41 and the second spring piece 42, and reducing the width of the mating portion 30 along the mating direction, the mating portion 30 can play a certain guiding role in mating the electronic component 3 between the first spring piece 41 and the second spring piece 42, thereby facilitating the mating of the electronic component 3 and the first spring piece 41 and the second spring piece 42.

[0103] Please refer to Figure 5-Figure 7 In some embodiments of the present application, at least one of the first elastic sheet 41 and the second elastic sheet 42 is formed into an arc-shaped structure.

[0104] In the above technical solution, by arranging at least one of the first spring piece 41 and the second spring piece 42 to form an arc-shaped structure, the structure of the corresponding spring piece can be simplified, and the plug-in convenience of the electronic component 3 can be improved.

[0105] For example, Figure 5-Figure 7 As shown, the first spring piece 41 and the second spring piece 42 are respectively formed into arc structures, and the openings of the two arc structures are arranged away from each other, so that the electronic component 3 can be more smoothly inserted between the first spring piece 41 and the second spring piece 42.

[0106] In the embodiment of the present application, there is no specific restriction on the structure of the first plug-in portion 11 and the second plug-in portion 21, as long as the first plug-in portion 11 and the second plug-in portion 21 can be plugged in and out of each other; for example, Figure 3-Figure 5In the example, the first plug-in portion 11 can be formed as a columnar structure, and the second plug-in portion 21 can be formed as a cylindrical structure, so that a mating hole is formed in the second plug-in portion 21, and the first plug-in portion 11 is suitable for being mated in the mating hole. Then, along the plugging direction of the first plug-in portion 11 and the second plug-in portion 21, the closer the distance between the plug 1 and the socket 2 is, the larger the contact area between the first plug-in portion 11 and the second plug-in portion 21 is.

[0107] In the second aspect, an embodiment of the present application provides a high-voltage electrical connection system 200, including a collection circuit 101, a collection device 102 and the above-mentioned electrical connector 100, the electronic component 3 is connected to the collection circuit 101 through a first connection part 100a and a second connection part 100b, and the collection device 102 is used to collect electrical parameters of the part of the electronic component 3 connected between the first connection part 100a and the second connection part 100b.

[0108] In the above technical solution, since the high-voltage electrical connection system 200 adopts the above-mentioned electrical connector 100, the safety of the high-voltage electrical connection system 200 can be improved, which is convenient for users to respond and handle in time.

[0109] Please refer to Figure 2 In some embodiments of the present application, there are multiple electrical connectors 100, each of which includes a first spring clip 41 and a second spring clip 42, wherein the first spring clip 41 is electrically connected to the first connection portion 100a, and the second spring clip 42 is electrically connected to the second connection portion 100b. In the first mating state and the second mating state, the resistor 33 is electrically connected between the first spring clip 41 and the second spring clip 42, and in the third mating state, the first spring clip 41 and the second spring clip 42 are electrically connected; parts of the multiple electronic components 3 connected between the first connection portion 100a and the second connection portion 100b are respectively connected in series to the acquisition circuit 101, and each of the electronic components 3 is a resistor structure. The acquisition device 102 is used to collect the total resistance of the multiple resistor structures connected in series to the acquisition circuit 101.

[0110] In the above technical solution, by connecting the first connection parts 100a and the second connection parts 100b of the plurality of electrical connectors 100 in series to the same acquisition circuit 101, even if one or more of the electrical connectors 100 are in the third mating state, the acquisition circuit 101 still maintains a connection state, and the resistance of the entire acquisition circuit 101 can still be collected by a collection device 102 to determine which electrical connector or connectors are in the third mating state and to determine which mating state the remaining electrical connectors are in. The collection device 102 collects the sum of the resistances of the plurality of electrical connectors 100 connected to the acquisition circuit 101; if the resistance structure configured for each electrical connector 100 can form a different combination of resistance values, it is convenient to determine the current state of all the electrical connectors 100 on the acquisition circuit 101 by a collection device 102, and the acquisition circuit 101 will not be disconnected due to one or more electrical connectors 100 being in the third mating state, and the resistance value of the acquisition circuit 101 cannot be collected, thereby achieving accurate diagnosis of the state of all the electrical connectors 100 in the acquisition circuit 101 and accurate fault location.

[0111] The resistance structure of the embodiment of the present application may be the variable resistor 32 or the resistor 33 described above.

[0112] Exemplarily, taking two electrical connectors 100 connected in series in the acquisition circuit 101 as an example, the resistance of one of the electrical connectors 100 connected in series in the acquisition circuit 101 in the first mating state is R1, the resistance of the second mating state is R2, and the resistance of the third mating state is basically 0; the resistance of the other electrical connector 100 connected in series in the acquisition circuit 101 in the first mating state is R3, the resistance of the second mating state is R4, and the resistance of the third mating state is basically 0; wherein, the resistance values ​​of any two of R1, R2, R3, R4, R1+R3, R1+R4, R2+R3, and R2+R4 are not equal, then the acquisition device 102 can accurately judge the current mating state of each electrical connector 100 by collecting the total resistance of multiple resistance structures in the acquisition circuit 101 connected in series to the acquisition circuit 101. Of course, the number of electrical connectors 100 connected in series in the acquisition loop 101 may be three or more.

[0113] Optionally, the acquisition device 102 is an MCU (controller), and the acquisition loop 101 is an MCU diagnostic loop.

[0114] In some other embodiments, the electronic components 3 include capacitors 31, and the electronic components 3 of the multiple electrical connectors 100 are all connected to the collection circuit 101, and the collection device 102 is used to collect the total capacitance value in the collection circuit 101. It can be understood that for the multiple capacitors 31 in the above-mentioned collection circuit 101, the multiple capacitors 31 can be arranged in series, so that the multiple capacitors 31 are all connected in series in the collection circuit 101; or, the multiple capacitors 31 can be arranged in parallel; or, the multiple capacitors 31 are mixed, that is, the multiple capacitors 31 are both connected in series and in parallel.

[0115] In a third aspect, an embodiment of the present application provides an electrical device 1000 , comprising the above-mentioned high-voltage electrical connection system 200 .

[0116] In the above technical solution, since the electrical device 1000 adopts the above high-voltage electrical connection system 200, the use safety of the electrical device 1000 can be improved.

[0117] Please refer again Figure 5-Figure 7 , describing the electrical connector 100 of a specific embodiment of the present application.

[0118] In the embodiment of the present application, the electrical connector 100 is a high voltage connector and includes a plug 1 , a socket 2 , an electronic component 3 , a first spring clip 41 and a second spring clip 42 .

Among them, one end of the first elastic sheet 41 is fixedly connected to the first connection portion 100a, and one end of the second elastic sheet 42 is fixedly connected to the second connection portion 100b.

[0120] In the first mating state, the first resistor 331 and the second resistor 332 are electrically connected in parallel between the first spring clip 41 and the second spring clip 42. In the second mating state, the first resistor 331 is electrically connected between the first spring clip 41 and the second spring clip 42. In the third mating state, the resistor 33 is disconnected from the first spring clip 41 and the second spring clip 42, and the first spring clip 41 and the second spring clip 42 are freely bent and contact each other.

[0121] Among them, in the first mating state, the contact area between the first plug-in portion 11 and the second plug-in portion 21 is the largest and is S1; in the second mating state, the contact area between the first plug-in portion 11 and the second plug-in portion 21 is S2; in the third mating state, the contact area between the first plug-in portion 11 and the second plug-in portion 21 is 0, S1>S2>0.

[0122] In the above technical solution, interlocking indication of three mating states of the electrical connector 100 can be achieved. Through targeted strategies, the safety and reliability of the high-voltage electrical connection system 200 can be improved, making it convenient for users to make corresponding processing according to the mating state of the electrical connector.

[0123] In the vehicle high-voltage system, each high-voltage load requires a high-voltage connector to be connected to the power battery. In order to save diagnostic costs, multiple electrical connectors 100 are connected in series and then detected and diagnosed through a collection device 102 (such as voltage, current or PWM waveform (pulse width modulation, etc.)). When a single electrical connector 100 is in a completely disconnected state, the collection circuit 101 will not immediately enter an open circuit state, and the collection device 102 can still perform diagnosis and locate and process the fault of the failed disconnected electrical connector 100.

[0124] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0125] The above are only preferred embodiments of the present application and are not intended to limit the present application.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
