[0036] Specifically, the power cable plug is an electrical component used to connect a power source and an electrical device, and usually includes three main parts: a plug body 1, a tension sensing device 2, and an early warning device 3; the plug body 1 refers to the main part of the power cable plug, which is usually made of an insulating material that is resistant to high temperature and high voltage, and has a cable connection part inside, which is used to connect to a power cable 4 or an electrical device; the tension sensing device 2 is a special device that can sense the tension of the power cable 4 and transmit the tension information to the early warning device 3; the early warning device 3 is a special device that determines whether the tension on the power cable 4 exceeds a predetermined value based on the tension information transmitted by the tension sensing device 2, and sends a warning signal if it exceeds the predetermined value; the predetermined value is a safety threshold preset by the early warning device 3, and when the tension on the power cable 4 exceeds this threshold, the early warning device 3 will send a warning signal.

[0037] The power cable plug is an important interface of the power supply device, and its function is to provide stable power to the device. In some cases, the power cable 4 may be subjected to excessive tension, resulting in damage to the power cable 4 or abnormality of the power supply device. In order to solve this problem, the utility model proposes a power cable plug with tension sensing and early warning functions. The tension of the power cable 4 is sensed by the tension sensing device 2, and the tension information is transmitted to the early warning device 3. The early warning device 3 sends a warning signal when it is determined that the tension exceeds a predetermined value, thereby promptly detecting abnormalities in the power cable 4 and ensuring the safe and stable operation of the power supply device.

[0038] In a possible implementation, the power cable plug includes a plug body 1, a tension sensing device 2 and an early warning device 3.

In addition, this power cable plug can also improve the reliability of the power system and ensure stable power supply.

[0043] Embodiment 2

[0044] On the basis of the above-mentioned embodiment 1, the embodiment of the present application further provides another power cable plug, including: a plug body 1, a tension sensing device 2, and an early warning device 3, such as Figure 1As shown:

[0045] The tension sensing device 2 is connected to the plug body 1, the early warning device 3 is connected to the tension sensing device 2, the power cable 4 passes through the tension sensing device 2 and is connected to the plug body 1, the tension sensing device 2 senses the tension of the power cable 4 and transmits the tension information to the early warning device 3, and the early warning device 3 sends a warning signal when it is determined that the tension exceeds a predetermined value.

[0046] It should be noted that the specific implementation method and technical effects of this embodiment please refer to the above-mentioned embodiment 1, which will not be repeated here.

[0047] In a preferred embodiment, the tension sensing device 2 includes: an elastic member 5 and a pressure sensor 6; the elastic member 5 is connected to the pressure sensor 6, and is used to generate a certain resistance to the power cable 4 when the power cable 4 passes through, and the pressure sensor 6 is used to sense the deformation of the elastic member 5, thereby determining the tension exerted on the power cable 4.

[0048] Specifically, the elastic member 5 refers to a component that can be deformed under the action of force, and is usually made of elastic material; the pressure sensor 6 is a device that can sense and transmit pressure signals, which can sense the deformation of the elastic member 5 and thus determine the tension exerted on the power cable 4.

[0049] In one possible implementation, the power cable plug includes a plug body 1, a tension sensing device 2 and an early warning device 3. The plug body 1 is the main part of the power cable plug, and is equipped with a power interface for connecting to a power device or a power cable 4. The tension sensing device 2 is connected to the plug body 1, and includes an elastic member 5 and a pressure sensor 6. The elastic member 5 generates a certain resistance to the power cable 4 when the power cable 4 passes through, and transmits this resistance to the pressure sensor 6. The pressure sensor 6 senses the deformation of the elastic member 5, thereby determining the tension exerted on the power cable 4. The early warning device 3 receives the tension information transmitted by the tension sensing device 2, and determines whether the power cable 4 is in an abnormal state based on the tension information. When it is determined that the tension exceeds a predetermined value, the early warning device 3 sends a warning signal.

[0050] In this embodiment, the pressure sensor 6 senses the deformation of the elastic member 5 to indirectly measure the tension on the power cable 4. This method can more accurately reflect the actual stress condition of the power cable 4 and has a fast response speed and high accuracy.

[0051] In a preferred embodiment, the tension sensing device 2 also includes a spherical universal clamp 7, which is rotatably connected to the elastic member 5. The power cable 4 passes through the spherical universal clamp 7 and is clamped at the penetration point, so as to keep the surface tension of the power cable 4 at the connection point consistent when the angle between the power cable 4 and the plug is different. Figure 2 is a schematic diagram of the principle structure of a power cable plug including a spherical universal clamp 7 assembly provided according to an embodiment of the present application, such as Figure 2 shown.

[0052] Specifically, the spherical universal clamp 7 is a clamp with a spherical shape, which can be rotatably connected to the elastic member 5 and is used to fix the power cable 4 so that the surface tension of the power cable 4 at the connection can be kept consistent even when the angles between the power cable 4 and the plug are different.

[0053] Since conventional power plugs usually have a fixed connection mode, they may be disturbed by external forces during use, resulting in unstable connection or power interruption. In particular, when the connection direction needs to be adjusted or the power plug needs to be dragged, the surface tension of the power cable 4 at the connection point is inconsistent when the angle between the power cable 4 and the plug is different. Conventional power plugs are easily damaged and have certain usage limitations. Therefore, this embodiment proposes a universal anti-drag power plug.

[0054] In a possible implementation, the power cable plug includes a plug body 1, a tension sensing device 2 and an early warning device 3. The plug body 1 is the main part of the power cable plug, and a power interface is installed inside it for connecting with a power supply device or a power cable 4. The tension sensing device 2 is connected to the plug body 1, and includes an elastic member 5, a pressure sensor 6 and a spherical universal clamp 7. The elastic member 5 generates a certain resistance to the power cable 4 when it passes through, and transmits this resistance to the pressure sensor 6. At the same time, the spherical universal clamp 7 is rotatably connected to the elastic member 5, and the surface tension of the power cable 4 at the connection can be kept consistent while the angle between the power cable 4 and the plug is different by clamping the power cable 4. The pressure sensor 6 senses the deformation of the elastic member 5, thereby determining the tension on the power cable 4. The early warning device 3 receives the tension information transmitted by the tension sensing device 2, and determines whether the power cable 4 is in an abnormal state according to the tension information. When it is determined that the tension exceeds a predetermined value, the early warning device 3 sends a warning signal.

[0055] In this embodiment, by using the design of a spherical universal clamp 7, the plug can adapt to different angles while maintaining a stable connection with the power cable 4, so that the power cable 4 can maintain a stable connection state in various usage environments, thereby improving the safety and stability of the power supply equipment.

[0056] In a preferred embodiment, the predetermined value includes a first predetermined value and a second predetermined value. If the warning device 3 determines that the pulling force exceeds the first predetermined value, a warning signal is issued; if the warning device 3 determines that the pulling force exceeds the second predetermined value, the power supply is cut off.

[0057] Specifically, the predetermined value refers to a set of thresholds jointly set by the early warning device 3 and the tension sensing device 2, including a first predetermined value and a second predetermined value. When the tension on the power cable 4 exceeds the predetermined value, an early warning will be triggered or the power will be cut off.

[0058] In order to be able to take different measures under different tension conditions, promptly detect abnormalities in the power cable 4 and take corresponding protective measures, thereby avoiding damage to the power cable 4 or abnormalities in the power supply equipment, optionally, the predetermined value is set to a first predetermined value and a second predetermined value of different sizes, and the second predetermined value is greater than the first predetermined value.

[0059] In a possible implementation, the early warning device 3 receives the tension information transmitted by the tension sensing device 2, and determines whether the power cable 4 is in an abnormal state according to the tension information. When it is determined that the tension exceeds a first predetermined value, the early warning device 3 sends a warning signal; when it is determined that the tension exceeds a second predetermined value, the early warning device 3 cuts off the power supply.

[0060] In this embodiment, by setting the first predetermined value and the second predetermined value, the plug can take different measures under different tension conditions, thereby better protecting the power supply device and the power cable 4. When the tension exceeds the first predetermined value, a warning signal is issued, which can promptly remind relevant personnel to pay attention and check the cable condition; and when the tension exceeds the second predetermined value, the power supply is cut off, which can prevent further damage to the cable and protect the device from further damage.

[0061] In a preferred embodiment, the warning signal includes a sound, light or vibration signal.

[0062] Specifically, a sound signal is a signal that transmits warning information by emitting sound, including but not limited to audio, voice, howling, etc.; a light signal is a signal that transmits warning information by emitting light, including but not limited to flash lights, LED lights, etc.; a vibration signal is a signal that transmits warning information through vibration, including but not limited to mobile phone vibration, mechanical vibration, etc.

[0063] Since the warning signal includes sound, light or vibration signal, relevant personnel can quickly and accurately understand the abnormal situation of the power cable 4 or the power supply equipment in different ways, so as to take corresponding measures in time to avoid damage to the power cable 4 or abnormality of the power supply equipment.

[0064] Specifically, the warning device 3 may choose to send out one or more of a sound signal, a light signal or a vibration signal to transmit the warning information.

[0065] In this embodiment, since the early warning signal includes sound, light or vibration signals, relevant personnel can quickly and accurately understand the abnormal situation of the power cable 4 or the power supply device in different ways, so as to take corresponding measures in time to avoid damage to the power cable 4 or abnormality of the power supply device. For example, if the operator is far away from the power supply device, he may not be able to directly observe the status of the power supply device, but through the sound signal or light signal emitted by the early warning device 3, the operator can quickly understand the abnormal situation of the power cable 4 or the power supply device; if the operator is doing other work and cannot always pay attention to the status of the power supply device, but through the vibration signal emitted by the early warning device 3, the operator can notice the problem of the power supply device in time. Therefore, the use of this utility model can improve the safety and stability of the power supply equipment and improve the reliability of the power system.

[0066] In a preferred embodiment, it further comprises a waterproof shell 8, which covers the surfaces of the plug body 1, the tension sensing device 2, and the early warning device 3, and is used to maintain the internal sealing of the power cable plug.

[0067] Specifically, the waterproof shell 8 is a shell covering the surface of the plug body 1, the tension sensing device 2, and the early warning device 3, and is used to improve the waterproof performance of the power cable plug and maintain the internal sealing.

[0068] In order to improve the waterproof performance and durability of the power cable plug, the utility model also proposes a power cable plug including a waterproof shell 8. The waterproof shell 8 can protect the tension sensing device 2, the early warning device 3 and other components inside the plug from external moisture, dust and the like, and maintain the internal sealing.

[0069] In a possible implementation, the power cable plug includes a plug body 1, a tension sensing device 2, an early warning device 3 and a waterproof shell 8. The waterproof shell 8 covers the surfaces of the plug body 1, the tension sensing device 2 and the early warning device 3 to maintain internal sealing.

[0070] In this embodiment, by providing a waterproof shell 8, the waterproof performance and durability of the power cable plug can be further improved. The waterproof shell 8 can effectively prevent moisture, dust, etc. from entering the inside of the plug, and protect the internal tension sensing device 2, early warning device 3 and other components from being affected, thereby ensuring the normal operation of the power cable plug. This design can also increase the overall service life of the power cable plug, so that it can maintain a good working condition under various environmental conditions. Therefore, the use of this utility model can improve the safety and stability of the power supply equipment and improve the reliability of the power system.

[0071] In a preferred embodiment, the waterproof housing 8 includes a waterproof sealing ring 9, and the waterproof sealing ring 9 is arranged at one end of the plug body 1 connecting the pins. Figure 3 is a schematic diagram of the principle structure of a power cable plug including a waterproof housing 8 component provided according to an embodiment of the present application, such as Figure 3 shown.

[0072] Specifically, the waterproof sealing ring 9 is an annular component arranged at one end of the connecting pin of the plug body 1, which is used to seal the gap between the pin and the socket when the plug is connected to the socket, thereby preventing moisture, dust, etc. from entering the interior of the power cable plug.

[0073] In order to further improve the waterproof performance and durability of the power cable plug, optionally, the utility model also proposes that the power cable plug includes a waterproof shell 8 with a waterproof sealing ring 9, which is used to protect the connecting part between the plug and the socket from external moisture, maintain internal sealing, and ensure safety of use.

[0074] The waterproof housing 8 includes a waterproof sealing ring 9, which is arranged at one end of the plug body 1 connected to the pin. The reason for this design is that the waterproof sealing ring 9 can play a better sealing role when the plug is connected to the socket, preventing moisture, dust, etc. from entering the inside of the power cable plug through the gap between the pin and the socket. At the same time, the waterproof sealing ring 9 can also improve the dustproof performance of the plug, preventing dust and other impurities from entering the inside of the plug and affecting its normal operation.

[0075] In a preferred embodiment, the waterproof housing 8 is made of an insulating material that is resistant to high temperatures and high voltages.

[0076] Specifically, high temperature and high voltage resistant insulating materials refer to materials that can maintain their physical and chemical properties without being damaged or having their performance degraded under high temperature and high pressure environments.

[0077] The waterproof shell 8 is made of an insulating material that is resistant to high temperature and high pressure because such a material can maintain its waterproof performance and internal sealing under high temperature and high pressure environments. In power equipment, the power cable plug may encounter high temperature and high pressure conditions. If the waterproof shell 8 material is not resistant to high temperature and high pressure, its performance may be degraded or damaged under such conditions, thereby affecting the waterproof performance and durability of the plug. Therefore, it is necessary to select an insulating material that is resistant to high temperature and high pressure.

[0078] In this embodiment, since the waterproof housing 8 is made of high temperature and high pressure resistant insulating material, it can maintain its waterproof performance and durability under high temperature and high pressure environment, thereby improving the overall performance and service life of the plug. At the same time, the use of the utility model can improve the safety and stability of the power supply equipment and improve the reliability of the power system.

[0079] In a preferred embodiment, the waterproof housing 8 includes a switchable heat dissipation door, which is used to increase the heat dissipation efficiency of the plug in an environment without waterproofing requirements, or to provide waterproofing in an environment with waterproofing requirements.

[0080] Specifically, the switchable heat dissipation door refers to a door panel that can be opened and closed, which is arranged on the waterproof shell 8 and is used to meet different needs by opening or closing the heat dissipation door when the heat dissipation efficiency needs to be increased or waterproofing treatment needs to be performed.

[0081] The waterproof housing 8 includes a heat dissipation door that can be opened and closed, which can increase the heat dissipation efficiency in an environment without waterproof requirements, or provide waterproofing in an environment with waterproof requirements. This is because, when the power cable plug is working in a high temperature environment, if the waterproof housing 8 does not have a heat dissipation door, the temperature inside the plug may be too high, affecting its performance and life. If the waterproof housing 8 has a heat dissipation door that can be opened and closed, the heat dissipation door can be opened when necessary to improve the heat dissipation efficiency of the plug and avoid overheating problems. In an environment with waterproof requirements, closing the heat dissipation door can ensure the waterproof performance of the plug and prevent moisture from entering the inside of the plug.

[0082] In a possible implementation, the waterproof housing 8 includes a switchable heat dissipation door, which is arranged on the shell of the waterproof housing 8. Preferably, a plurality of heat dissipation holes are arranged on the shell of the waterproof housing 8, and the heat dissipation door adopts a push-pull design, and when the heat dissipation door is opened, the heat dissipation holes are opened, and when the heat dissipation door is closed, the heat dissipation holes are closed.

[0083] In this embodiment, since the waterproof housing 8 includes a heat dissipation door that can be opened and closed, the heat dissipation efficiency can be increased in an environment without waterproofing requirements, or waterproofing can be performed in an environment with waterproofing requirements. This design can maintain the waterproof performance of the plug without sacrificing the heat dissipation efficiency, and can also improve the heat dissipation efficiency when needed, thereby improving the overall performance and service life of the power cable plug. Therefore, the use of the utility model can improve the safety and stability of the power supply equipment and improve the reliability of the power system.

[0084] In a preferred embodiment, it also includes: a temperature sensor and an overload protector, wherein the temperature sensor is connected to the plug body 1 and is used to sense the temperature of the power cable 4, and the overload protector is connected to the temperature sensor and is used to cut off the power supply when the temperature exceeds a predetermined value.

[0085] Specifically, a temperature sensor refers to a device for sensing temperature, which can sense temperature changes in the surrounding environment and output corresponding electrical signals or digital signals; an overload protector is a circuit protection device that is used to cut off power supply when abnormal conditions such as overload or short circuit occur in the circuit to protect the circuit and equipment from damage.

[0086] In order to further enhance the safety and stability of the power cable plug, the power cable plug of the utility model further includes a temperature sensor and an overload protector. The temperature sensor can sense the temperature of the power cable 4 in real time. When the temperature exceeds a predetermined value, the overload protector can quickly cut off the power supply to prevent the power cable 4 or the power supply device from being damaged due to excessive temperature, thereby improving the safety and stability of the power cable plug.

[0087] In a possible implementation, a temperature sensor is connected to the plug body 1 to sense the temperature of the power cable 4. An overload protector is connected to the temperature sensor, and when the temperature exceeds a predetermined value, the overload protector quickly cuts off the power supply.

[0088] In this embodiment, due to the addition of a temperature sensor and an overload protector, the power supply can be quickly cut off when the temperature exceeds a predetermined value, thereby preventing the power cable 4 or the power supply device from being damaged due to excessive temperature, and enhancing the safety and stability of the power cable plug. At the same time, the safety, stability and reliability of the power supply device are improved, and the overall performance and service life of the plug are enhanced.

[0089] It can be seen that the power cable plug of the utility model has at least the following technical effects compared with the prior art:

[0090] The following functions are used to improve the safety and stability of power equipment, enhance the reliability of the power system, and optimize the performance of power cable plugs:

[0091] (1) Using a power cable plug with tension sensing and warning functions can monitor the tension of the power cable 4 in real time and send out a warning signal when the tension exceeds a predetermined value, thereby promptly reminding the operator or system to check or replace the power cable 4 to avoid damage to the power cable 4 or abnormality of the power supply equipment;

[0092] (2) The pressure sensor 6 senses the deformation of the elastic member 5 to indirectly measure the tension on the power cable 4. This method can more accurately reflect the actual force on the power cable 4 and has a fast response speed and high accuracy.

[0094] (4) By setting the first predetermined value and the second predetermined value, the plug can take different measures under different tension conditions, thereby better protecting the power supply device and the power cable 4;

[0095] (5) The warning signal includes sound, light or vibration signal, and the relevant personnel can quickly and accurately understand the abnormal situation of the power cable 4 or the power supply device through different methods, so as to take corresponding measures in time to avoid damage to the power cable 4 or abnormality of the power supply device;
