[0035] In one embodiment, Figure 1 A schematic diagram of the structure of an electrical connector for a vehicle provided by an embodiment of the present invention, Figure 2 A schematic cross-sectional structure diagram of a socket provided by an embodiment of the present invention, Figure 3 A schematic diagram of the structure of the direction of the magnetic field formed after the coil is energized according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the structure of a magnetorheological fluid under the action of a magnetic field provided by an embodiment of the present invention. This embodiment can be applied to connect different devices in a vehicle under different working conditions to achieve normal signal transmission between devices. The electrical connector can be configured in the vehicle. Figures 1 to 4 As shown, the electrical connector includes a plug 1 and a socket 2; the plug 1 includes a pin 11, one end of which is connected to a connecting line of a first device; the socket 2 includes a slot 21 and a coil 22, and the slot 21 is connected to a connecting line of a second device; the other end of the pin 11 is used to be inserted into the slot 21, and the pin 11 and the slot 21 are respectively provided with a slot 12 that is aligned with each other when the pin 11 is inserted into place, and the slot 12 contains magnetorheological fluid; when the coil 22 is energized to form a magnetic field, the magnetic particles in the magnetorheological fluid are transformed from liquid to solid-like magnetic chains under the action of the magnetic field, so as to position the relative movement of the pin 11 and the slot 21.

[0036] Among them, the plug 1 and the socket 2 are used to connect two different devices in the vehicle to realize signal transmission between the two devices. The pin 11 is a conductive structure with a certain shape. In this embodiment, the material of the pin 11 may include but is not limited to metal conductive materials such as copper. One end of the pin 11 is used to connect the connecting wire of the first device (not shown in the figure), and the other end is used to be inserted into the slot 21. The slot 21 is connected to the connecting wire of the second device (not shown in the figure). After the pin 11 is inserted into the slot 21, the electrical signal of the first device can be transmitted from the connecting wire of the second device to the second device through the connecting wire and the pin 11, thereby realizing signal transmission between the two devices. In this embodiment, the first device and the second device can be any device in the vehicle that needs to transmit signals, such as a power supply, a sensor or a vehicle controller, etc., which can be determined according to actual conditions and is not limited here. The coil 22 is a ring-shaped wire winding. After a voltage is applied to the coil 22, a magnetic field is generated around the coil 22. Magnetorheological fluid is a suspension composed of tiny soft magnetic particles with high magnetic permeability and low magnetic hysteresis and non-magnetic conductive liquid. It is a new type of intelligent material that has both liquid fluidity and solid magnetic material properties. Under the action of an external magnetic field, its performance can change from fluidity to a rigid state similar to a solid. This change is due to the fact that the magnetic particles in the magnetorheological fluid form a chain structure under the action of the magnetic field, which increases the viscosity and shear stress of the liquid, thereby producing a higher rigidity.

[0037] Specifically, one end of the pin 11 is connected to the connection line of the first device, and the slot 21 is connected to the connection line of the second device. After the other end of the pin 11 is inserted into the slot 21 and inserted into place, it indicates that the first device and the second device are now connected through the electrical connector. In order to ensure that the first device and the second device can transmit signals normally under different working conditions, the present embodiment is respectively provided with a card slot 12 on the pin 11 and the slot 21, which are aligned with each other when the pin 11 is inserted into place. The card slot 12 contains magnetorheological fluid. By applying voltage to the coil 22, the coil 22 is energized. After the coil 22 is energized, a magnetic field in a certain direction is generated. The direction of the magnetic field is perpendicular to the insertion direction of the pin 11 when it is inserted into the slot 21. The generated magnetic field is referenced Figure 3 As shown, the coil 22 is located directly below the magnetorheological fluid, and the magnetic particles of the magnetorheological fluid will change under the action of the magnetic field, from liquid to solid-like magnetic chain structure, refer to Figure 4 As shown, the magnetic linkage structure is located in the slot 12 where the pin 11 and the slot 21 are aligned, so as to position the relative movement of the pin 11 and the slot 21, so that the plug 1 and the socket 2 are tightly connected, thereby ensuring the normal use of the electrical connector when the vehicle encounters a bumpy road or an uneven road in poor working conditions, thereby achieving normal transmission of signals between the first device and the second device.

[0038] It can be understood that the number of pins 11, slots 21 and coils 22 is multiple, and each pin 11, slot 21 and coil 22 extends in parallel and is arranged in sequence in the same direction; different pins 11 are connected to different connecting wires of the first device, and different slots 21 are connected to different connecting wires of the second device. In other words, in order to ensure the manufacturing cost of the electrical connector and the integration of the vehicle, when the electrical connector is actually prepared, multiple pins 11 can be set on the plug 1, and correspondingly, each pin 11 will correspond to a slot 21 and a coil 22, that is, the number of pins 11, slots 21 and coils 22 is equal. In addition, the pins 11, slots 21 and coils 22 extend in parallel and are arranged in sequence in the same direction. For example, refer to Figure 1 and Figure 2 , the number of pins 11, slots 21 and coils 22 are all three. When connecting the first device and the second device, one end of different pins 11 can be connected to the connecting wires of different first devices, and different slots 21 can be connected to the connecting wires of different second devices, and each pin 11 is inserted into each slot 21 accordingly, so that a magnetic field is generated by applying a voltage to each coil 22, and the magnetorheological fluid in each slot 12 forms a magnetic chain structure under the action of the magnetic field, thereby ensuring the normal transmission of signals between different first devices and second devices.

[0039] The technical solution of the embodiment of the present invention is to provide an electrical connector including a plug and a socket, wherein a coil is provided in the socket, and after the pin is inserted into the slot, a slot for accommodating magnetorheological fluid is provided in the pin and the slot. By applying voltage to the coil, the coil generates a magnetic field perpendicular to the insertion direction of the pin, and the magnetorheological fluid forms a rigid-body-like magnetic flux structure under the action of the magnetic field. The magnetic flux structure is located in the slot where the pin and the slot are aligned, so as to position the relative movement of the pin and the slot. Through the above structure, the characteristics of the coil and the magnetorheological fluid are utilized, so that the normal operation of the electrical connector is still guaranteed under harsh working conditions, and the normal and stable transmission of signals between the first device and the second device is realized.

[0040] Optional, Figure 5 A schematic diagram of a control coil energization structure provided by an embodiment of the present invention, referring to Figure 5 As shown, the vehicle includes a vehicle controller 3 and an acceleration sensor 4; the vehicle controller 3 is communicatively connected to the acceleration sensor 4, and the vehicle controller 3 is electrically connected to the coil 22; the acceleration sensor 4 is used to collect the acceleration of the vehicle and send the acceleration signal to the vehicle controller 3, and the vehicle controller 3 is used to receive the acceleration signal and control the coil 22 to be energized when the acceleration reaches a preset acceleration.

[0041] Specifically, when the control coil 22 is energized to generate a magnetic field, the acceleration of the vehicle can be collected through the acceleration sensor 4, and the acceleration signal can be sent to the vehicle controller 3 in real time. The vehicle controller 3 is the core controller of the vehicle, which can communicate with the acceleration sensor 4, receive the acceleration signal generated by the acceleration sensor 4, and control the coil 22 to be energized according to the acceleration signal. When the acceleration reaches the preset acceleration, it indicates that the user will quickly pass through a road with poor working conditions if he continues to drive at this speed, causing the electrical connector to fail. Therefore, the vehicle controller 3 will control the coil 22 to be energized, so that the coil 22 generates a magnetic field, and then the magnetic particles of the magnetorheological fluid contained in the card slot 12 are transformed from liquid to a solid-like magnetic chain structure under the action of the magnetic field, ensuring that the pin 11 and the slot 21 do not move relative to each other.

[0042] Optional, Figure 6 Another schematic diagram of the structure of the control coil energization provided by the embodiment of the present invention, refer to Figure 6 As shown, the vehicle includes a motor 5 and a high-voltage controller 6, a three-phase line is electrically connected between the high-voltage controller 6 and the motor 5, and the high-voltage controller 6 is used to provide a three-phase alternating current to the motor 5; the three-phase line includes a shielding layer, and the coil 22 is electrically connected between the three-phase current output end of the shielding layer and the power supply voltage end GND; when the vehicle is working, the shielding layer generates a three-phase alternating current to energize the coil 22.

[0043] Among them, the power supply voltage end is the ground voltage GND. The motor 5 is a device that converts electrical energy into mechanical energy. The high-voltage controller 6 is a device used to manage and adjust the high-voltage system. Usually, the other end of the high-voltage controller 6 is connected to the battery pack, and the battery pack can power the high-voltage controller 6. The high-voltage controller 6 is responsible for monitoring and adjusting the DC voltage output by the battery pack, and converting it into three-phase AC power for the vehicle's motor 5, that is, providing three-phase AC current to the motor 5. A three-phase line is connected between the high-voltage controller 6 and the motor 5. The three-phase line includes a shielding layer. When the high-voltage controller 6 provides three-phase AC current to the motor 5, the shielding layer also generates three-phase AC current. The generated three-phase AC current is output to the coil 22 to power the coil 22.

[0044] Specifically, when the vehicle is running, the motor 5 and the high-voltage controller 6 in the vehicle are both working normally. At this time, the high-voltage controller 6 will provide three-phase AC current to the motor 5, and three-phase AC current will also be generated in the shielding layer. The magnitude of the three-phase AC current generated by the shielding layer is usually between 5A and 30A. When the three-phase AC current is output from the shielding layer, it will flow into the coil 22, start to supply power to the coil 22, and generate a magnetic field. The generated magnetic field causes the magnetic particles of the magnetorheological fluid placed in the card slot 12 to change from liquid to a solid-like magnetic chain structure under the action of the magnetic field, ensuring that the pin 11 and the slot 21 do not move relative to each other. When the vehicle stops running, the motor 5 and the high-voltage controller 6 also stop working. At this time, since the vehicle is not running, there is no source of vibration, and there is no problem of electrical connection failure due to poor working conditions. At this time, the shielding layer does not generate three-phase AC current, the coil 22 is not energized, and no magnetic field is generated. The magnetorheological fluid is in a liquid state.

[0045] Optional, continue to refer to Figure 1 and Figure 2 The slot 21 includes a first card slot 121, and the socket 2 also includes an introduction hole 23; the introduction hole 23 and the first card slot 121 pass through the socket 2, and the introduction hole 23 is used to introduce the magnetorheological fluid; the coil 22 is located on the side of the slot 21 away from the introduction hole 23, and is aligned with the introduction hole 23.

[0046] Optionally, the introduction hole 23 is a one-way introduction hole.

[0047] Optionally, the plug pin 11 includes a second slot 122 ; the second slot 122 is located in a central area of ​​the plug pin 11 .

[0048] Specifically, the first card slot 121 and the second card slot 122 can be circular card slot structures, and of course can also be other shapes such as square or rectangular, which are not limited here. The introduction hole 23 is located on the socket 2, and the introduction hole 23 and the first card slot 121 penetrate the socket 2, so that the magnetorheological fluid can be introduced into the first card slot 121 and the second card slot 122 through the introduction hole 23. It should be noted that when the electrical connector is used for the first time, that is, the coil 22 has not been energized, after the pin 11 and the slot 21 are inserted into place, when the magnetorheological fluid is introduced from the introduction hole 23 of the socket 2, it will not enter the card slot 12, but will be in the introduction hole 23. When the coil 22 is energized, a magnetic field will be generated, and the magnetic field causes the magnetorheological fluid to form a magnetic chain structure, thereby forming a connection between the pin 11 and the slot 21. When the coil 22 stops being energized, the magnetic field disappears, and the magnetorheological fluid at this time will enter the card slot 12 under the action of gravity. At this time, the card slot 12 is used to accommodate the magnetorheological fluid. In addition, in this embodiment, the introduction hole 23 is a one-way introduction hole, that is, after the magnetorheological fluid enters the introduction hole 23, it will no longer flow out of the introduction hole 23, thereby ensuring that the magnetorheological fluid can normally connect the pin 11 and the slot 21 under the action of the magnetic field.

[0049] It should be noted that the pin 11 and the slot 21 are respectively provided with a slot 12 that is aligned with each other when the pin 11 is inserted into place, and the slot 12 includes a second slot 122 and a first slot 121, the second slot 122 is located on the pin 11, and the first slot 121 is located on the socket 2. When the pin 11 is inserted into the slot 21 and is in place, the first slot 121 and the second slot 122 are aligned and connected. When the coil 22 is energized, a magnetic field is generated around the coil 22, and the magnetorheological fluid is transformed from a liquid to a solid-like magnetic flux structure under the action of the magnetic field. At this time, the magnetic flux structure is located in the first slot 121 and the second slot 122 to position the relative movement of the pin 11 and the slot 21.

[0050] Optional, reference Figure 1 The plug 1 further includes a first connecting groove (not shown in the figure), which is connected to one end of the pin 11; the connecting wire of the first device is placed in the first connecting groove.

[0051] Optionally, the socket 2 further includes a second connecting groove (not shown in the figure), which is connected to the slot 21; and a connecting line of the second device is placed in the second connecting groove.

The position of the first connection groove can be determined according to actual conditions, for example, it can be set in parallel with one end of the pin 11, set perpendicular to one end of the pin 11, or set at a preset angle to one end of the pin 11, and no limitation is made here. Similarly, when the connection line of the second device is connected to one end of the slot 21, a second connection groove can be set on the socket 2, and the second connection groove is connected to the slot 21 to accommodate the connection line of the second device. The position of the second connection groove can be determined according to actual conditions, for example, it can be set in parallel with one end of the slot 21, set perpendicular to one end of the slot 21, or set at a preset angle to one end of the slot 21, and no limitation is made here.

For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0055] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors.
