[0040] With the increasing popularity of new energy vehicles, more and more consumers are purchasing them. When charging a new energy vehicle, many external components can also heat up. For example, when consumers plug a charging gun into a power strip to charge their new energy vehicle, the power strip's connecting wires generate significant heat, creating a significant fire hazard.

[0041] In light of this, the present invention proposes a plug temperature sensing assembly. By installing a temperature sensing module 2 on a plug assembly 1, the temperature signal sensed by the temperature sensing module 2 can be promptly transmitted to the plug assembly 1. By configuring the temperature sensing module 2 so that the temperature sensor 21 is connected to one end of an external wire 23, and the other end of the external wire 23 is connected to the plug assembly 1, the temperature signal outside the plug assembly 1 can be promptly obtained. A first cable 4 is provided to further transmit the temperature signal to a connected device 3, allowing the device 3 to perform further operations based on the temperature signal, thereby ensuring timely monitoring of external device temperatures and preventing fires.

[0042] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0043] like Figure 1-6 The embodiment of the present invention proposes a plug temperature sensing component, which includes a plug component 1, a temperature sensing module 2 and a first cable 4; the plug component 1 is provided with a plug-in portion 14, and the plug-in portion 14 is plugged into the socket 53; the temperature sensing module 2 includes an external wire 23, one end of the external wire 23 is connected to the temperature sensor 21, and the other end of the external wire 23 is connected to the plug component 1; one end of the first cable 4 is connected to the plug component 1, and the other end of the first cable 4 is connected to the device 3; wherein, the external wire 23 transmits the temperature signal of the temperature sensor 21 to the plug component 1, and then transmitted to the device 3 by the first cable 4.

[0044] In the technical solution adopted in this embodiment, the plug temperature sensing component has a plug component 1, and the plug component 1 is provided with a plug-in portion 14, which can be plugged into the socket 53. The socket 53 can be a fixed socket fixed to the wall, or it can be a socket 53 on the power strip 5. Preferably, the socket 53 is the socket 53 on the power strip 5. The temperature sensing module 2 includes a temperature sensor 21 and an external wire 23 connected to the temperature sensor 21. The temperature sensor 21 can sense the ambient temperature and output the temperature signal through the external wire 23. The other side of the external wire 23 is connected to the plug component 1, thereby transmitting the temperature signal to the plug component 1. The plug temperature sensing component also includes a first cable 4, one end of the first cable 4 is connected to the plug component 1, and the other end of the first cable 4 is connected to the device 3. With this arrangement, after the temperature signal is transmitted to the plug component 1 through the external wire 23, it can be further transmitted to the device 3 through the first cable 4. It is understandable that the external wire 23 can be fixedly connected to the plug assembly 1 in a variety of ways. For example, the end of the external wire 23 away from the temperature sensor 21 is directly fixedly connected to the conductive terminal in the plug assembly 1, and the other end of the conductive terminal is connected to the signal line 42 in the first cable 4, so as to realize the transmission of the temperature signal. It is understandable that the end of the external wire 23 away from the temperature sensor 21 can also be inserted into the inner cavity of the plug assembly 1 and directly fixedly connected to the end of the first cable 4 close to the plug assembly 1. Preferably, the fixed connection method can be crimping, welding, etc., which is not limited here. It is understandable that the end of the external wire 23 away from the temperature sensor 21 can also be detachably connected to the plug assembly 1.

[0045] It is understood that when the socket 53 is a socket 53 on a power strip 5, the temperature sensor 21 can be fixed to the connecting wire 52 of the power strip 5. In this way, the device 3 can obtain the temperature of the connecting wire 52 in real time. In this case, when the temperature of the connecting wire 52 is abnormal, the device 3 can perform the next operation, such as alarming, cutting off the charging current, reducing the charging current, etc., thereby preventing the connecting wire 52 from overheating and causing safety hazards.

[0046] Preferably, Figure 6 As shown, the first cable 4 includes an outer layer 43, a cavity is formed in the outer layer 43, a power line 41 and a signal line 42 are provided in the cavity, one end of the power line 41 extends into the plug assembly 1 to be conductively connected to the plug-in portion 14 of the plug assembly 1, and one end of the power line 41 extends into the plug assembly 1 to be conductively connected to the external wire 23.

[0047] Further, such as Figure 1-2 As shown, in one embodiment of the present invention, the plug assembly 1 is a plug connector 11 , and the plug connector 11 is connected to the external wire 23 .

[0048] In the technical solution adopted in this embodiment, the plug assembly 1 is a plug connector 11 having a first plug terminal 111. Preferably, the first plug terminal 111 can be directly plugged into the socket 53. One end of the external wire 23 is connected to the temperature sensor 21, and the other end of the external wire 23 is connected to the plug connector 11, thereby transmitting the temperature signal to the plug connector 11.

[0049] It is understood that the external wire 23 can be connected to the plug connector 11 in a variety of ways. For example, the external wire 23 can be fixedly connected to the conductive terminals within the housing 112 of the plug connector 11, or the external wire 23 can be fixedly connected to the signal wire 42 of the first cable 4 within the plug connector 11. When the external wire 23 is fixedly connected to the conductive terminals within the plug connector 11, the end of the external wire 23 away from the temperature sensor 21 is directly connected to the conductive terminals within the plug connector 11, and the other end of the conductive terminals is connected to the signal wire 42 of the first cable 4, thereby transmitting the temperature signal. When the external wire 23 is fixedly connected to the signal wire 42 of the first cable 4 within the plug connector 11, the end of the external wire 23 away from the temperature sensor 21 can also be inserted into the inner cavity of the plug connector 11 and directly connected to the end of the first cable 4 near the plug connector 11. Preferably, the fixed connection method can be crimping, welding, etc., which is not limited here. It is understood that the end of the external wire 23 away from the temperature sensor 21 can also be detachably connected to the plug connector 11.

[0050] Further, such as Figure 2 As shown, in one embodiment of the present invention, a temperature sensing jack 13 is provided on the plug connector 11, and a pin 24 is further provided at one end of the external wire 23 away from the temperature sensor 21. The pin 24 can be detachably connected to the temperature sensing jack 13 to transmit the temperature signal to the plug connector 11.

[0051] In the technical solution adopted in this embodiment, the external wire 23 and the plug connector 11 can be detachably connected. The plug connector 11 is provided with a temperature sensing jack 13. The end of the external wire 23 away from the temperature sensor 21 is also provided with a pin 24. The pin 24 is detachably connected to the temperature sensing jack 13 to transmit the temperature signal to the plug connector 11. By providing a detachable connection between the temperature sensing module 2 and the plug connector 11, the application range of the plug connector 11 is enriched. When it is necessary to measure the temperature of an external device, it is only necessary to insert the pin 24 of the external wire 23 into the temperature sensing jack 13 and then fix the temperature sensor 21 to the external device. The device 3 can then obtain the temperature signal of the external device in real time.

[0052] Furthermore, in one embodiment of the present invention, a transfer terminal is further provided in the plug connector 11 , one end of the transfer terminal is connected to the pin 24 through the temperature sensing jack 13 , and the other end of the transfer terminal is connected to the first cable 4 .

[0053] In the technical solution adopted in this embodiment, a transfer terminal is provided within the plug connector 11. One end of the transfer terminal is electrically connected to the pin 24 via the temperature sensing jack 13, and the other end of the transfer terminal is electrically connected to the first cable 4. With this arrangement, when the pin 24 is inserted into the temperature sensing jack 13, the pin 24 is electrically connected to the transfer terminal via the temperature sensing jack 13, thereby transmitting the temperature signal to the first cable 4 via the transfer terminal.

[0054] Further, such as Figure 3-5 As shown, in another embodiment of the present invention, the plug assembly 1 includes a conversion head 12 and a plug connector 11 , and the conversion head 12 is connected to the external wire 23 .

[0055] It is understood that when the plug connector 11 and the socket 53 do not match, a conversion head 12 can be installed between the plug connector 11 and the socket 53. One end of the conversion head 12 is provided with a second plug terminal 121, which is used to plug into the socket 53. The other end of the conversion head 12 is provided with a conversion socket 122, into which the first plug terminal 111 of the plug connector 11 can be inserted. During power transmission, the electrical energy in the socket 53 is transmitted to the conversion head 12 through the second plug terminal 121, and is simultaneously transmitted through the conversion socket 122 to the first plug terminal 111 connected to the conversion socket 122, and then transmitted to the device 3 through the first cable 4. It is understood that at this time, the external wire 23 can be connected to either the plug connector 11 or the conversion head 12. Preferably, the external wire 23 is connected to the conversion head 12.

[0056] Further, such as Figure 3-5 As shown, in one embodiment of the present invention, the conversion head 12 is further provided with a probe hole 124 on the side facing the plug connector 11, and the plug connector 11 is provided with a probe 113 corresponding to the probe hole 124, and the external wire 23 is conductively connected to the probe 113 through the probe hole 124 to transmit the temperature signal to the plug connector 11.

[0057] It can be understood that when the conversion head 12 and the external wire 23 are connected, by not setting the probe hole 124 on the conversion head 12 and setting the probe 113 on the plug connector 11, the temperature signal transmitted from the external wire 23 can be transmitted to the probe 113 connected thereto through the probe hole 124, thereby transmitting the temperature signal to the plug connector 11.

[0058] It is understandable that the external wire 23 can be connected to the conversion head 12 in a variety of ways. For example, the external wire 23 can be fixedly connected to the conductive terminal in the housing 123 of the conversion head 12, or the external wire 23 can be fixedly connected to the probe hole 124 on the housing 123 of the conversion head 12. When the external wire 23 is fixedly connected to the conductive terminal in the conversion head 12, the end of the external wire 23 away from the temperature sensor 21 is directly fixedly connected to one end of the conductive terminal in the conversion head 12, and the other end of the conductive terminal is connected to the probe hole 124, thereby transmitting the temperature signal to the probe hole 124. When the external wire 23 is fixedly connected to the probe hole 124 on the conversion head 12, the end of the external wire 23 away from the temperature sensor 21 can also pass through the housing 123 of the conversion head 12, enter its inner cavity, and directly establish a conductive connection with the probe hole 124. For example, it can be fixedly connected to the conductive component at the probe hole 124. Preferably, the fixed connection method can be crimping, welding, etc., which is not limited here. It is understandable that the end of the external wire 23 away from the temperature sensor 21 can also be detachably connected to the conversion head 12 .

[0059] Further, such as Figure 3-5 As shown, in one embodiment of the present invention, a temperature sensing jack 13 is provided on the conversion head 12, and a pin 24 is further provided at the end of the external wire 23 away from the temperature sensor 21. The pin 24 can be detachably connected to the temperature sensing jack 13 to transmit the temperature signal to the conversion head 12.

[0060] In the technical solution adopted in this embodiment, the external wire 23 and the conversion head 12 can be detachably connected. The conversion head 12 is provided with a temperature sensing jack 13. The end of the external wire 23 away from the temperature sensor 21 is also provided with a pin 24. The pin 24 is detachably connected to the temperature sensing jack 13 to transmit the temperature signal to the conversion head 12. By arranging the temperature sensing module 2 and the conversion head 12 in a detachable connection, the application range of the conversion head 12 is enriched. When it is necessary to measure the temperature of an external device, it is only necessary to insert the pin 24 of the external wire 23 into the temperature sensing jack 13, and then fix the temperature sensor 21 to the external device. The device 3 can then obtain the temperature signal of the external device in real time.

[0061] Further, such as Figure 3-5 As shown, in one embodiment of the present invention, a transfer terminal is further provided in the conversion head 12 , one end of the transfer terminal is connected to the pin 24 through the temperature sensing jack 13 , and the other end of the transfer terminal is connected to the probe 113 through the probe hole 124 .

[0062] In the technical solution adopted in this embodiment, a transfer terminal is provided inside the adapter. One end of the transfer terminal is connected to the pin 24 through the temperature sensing socket 13, and the other end of the transfer terminal is connected to the probe hole 124. In this arrangement, when the pin 24 is inserted into the temperature sensing socket 13, the pin 24 is conductively connected to one end of the transfer terminal through the temperature sensing socket 13, thereby transmitting the temperature signal to the probe hole 124 through the transfer terminal. When the plug connector 11 and the conversion head 12 are plugged in, the first plug terminal 111 is inserted into the conversion socket 122, and the probe 113 is inserted into the probe hole 124, and the temperature signal is transmitted from the probe hole 124 to the probe 113. It can be understood that the probe 113 is connected to the first cable 4. Preferably, the probe 113 is conductively connected to the signal line 42 in the first cable 4, so that the temperature signal can be input from the probe 113 into the first cable 4, and then transmitted to the device 3, so that the device 3 can perform further operations based on the level of the temperature signal. At this time, when the temperature of the connecting wire 52 is abnormal, the device 3 can perform the next operation, such as alarming, cutting off the charging current, reducing the charging current, etc., so as to prevent the connecting wire 52 from being overheated and causing safety hazards.

[0063] Further, such as Figure 1 、 3 As shown, in one embodiment of the present invention, the temperature sensing module 2 further includes a fixing module 22 , on which the temperature sensor 21 is provided, and the fixing module 22 fixes the temperature sensor 21 .

[0064] As will be appreciated, in order to stably secure the temperature sensor 21 to the external device, the temperature sensing module 2 further includes a securing module 22. Preferably, the securing module 22 is a strap. When the securing module 22 is a strap, the temperature sensor 21 is mounted on the strap, and Velcro is provided at both ends of the strap. If the external device is the connecting cable 52 of the power strip 5, the strap can be tied to the connecting cable 52 to ensure that the temperature sensor 21 is in close contact with the outer surface of the connecting cable 52, thereby enabling the temperature of the connecting cable 52 to be obtained in real time.

[0065] Furthermore, in one embodiment of the present invention, a temperature sensing module 2 is also provided on the first cable 4, and the temperature sensing module 2 includes an external wire 23, one end of the external wire 23 is connected to the temperature sensor 21, and the other end of the external wire 23 is connected to the first cable 4.

[0066] It is understood that the temperature sensing module 2 can be provided only on the plug assembly 1, or it can be provided on both the plug assembly 1 and the first cable 4. When the temperature sensing module 2 is also provided on the first cable, it can have the same structure as the temperature sensing module 2 connected to the plug assembly. This temperature sensing module 2 also includes an external wire 23 and a temperature sensor 21. One end of the external wire 23 is connected to the temperature sensor 21, and the other end of the external wire 23 is connected to the first cable 4.

[0067] Furthermore, in one embodiment of the present invention, the first cable 4 includes an outer layer 43, a cavity is formed in the outer layer 43, a power line 41 and a signal line 42 are provided in the cavity, and the end of the external wire 23 away from the temperature sensor 21 passes through the outer layer 43 to be connected to the signal line 42.

[0068] It is understandable that at the point where the end of the external wire 23 away from the temperature sensor 21 passes through the outer layer 43 , the gap between the external wire 23 and the outer layer 43 can be filled with insulating sealant for insulation sealing to prevent leakage.

[0069] like Figure 1-6 As shown, an embodiment of the present invention further proposes a charging device, which includes a second cable 33, a control box 31, a charging gun 32 and a plug temperature sensing component as described above, wherein the plug temperature sensing component is connected to the control box 31 through a first cable 4, and the control box 31 is connected to the charging gun 32 through the second cable 33.

[0070] It can be understood that the first cable 4 of the plug temperature sensing component is connected to the control box 31 to transmit the temperature signal to the inside of the control box 31, so that the control box 31 can perform further operations according to the level of the temperature signal.

[0071] Furthermore, in an embodiment of the present invention, the control box 31 further includes a control module, which controls the charging gun 32 to stop charging and / or issue an alarm signal when the temperature signal is greater than a threshold.

[0072] Furthermore, in an embodiment of the present invention, the control box 31 further includes a control module, which reduces the charging current of the charging gun 32 and / or issues an alarm signal when the temperature signal is greater than a threshold.

[0073] It is understandable that the control box 31 also includes a control module, which can perform further operations according to the level of the temperature signal, such as alarming, cutting off charging, reducing charging current, etc., so as to prevent the connection line 52 from being overheated and causing safety hazards. Preferably, the control module reduces the charging current of the charging gun 32 when the temperature signal is greater than the threshold. Preferably, the control module reduces the charging current of the charging gun 32 when the temperature signal is greater than the threshold. Preferably, the control module can also send an alarm signal when the temperature signal is greater than the threshold. Since the plug temperature sensing component adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
