[0035] The embodiment of the present invention provides an overhead cable 400 tap, which is used for tapping cables 400. The overhead cable 400 tap includes: a socket, a tap plug 200 and a sealing cap 300. The socket includes at least two sockets 140; one end of the tap plug 200 is electrically connected to the socket, and one end of the tap plug 200 is electrically connected to the cable 400; the sealing cap 300 is movably arranged on the socket 140, and the sealing cap 300 is used to insulate the socket 140. The socket includes at least two sockets 140, allowing multiple cables 400 to be connected at the same time, realizing flexible cable 400 tapping, and is suitable for scenarios where multiple cables 400 need to be tapped. One end of the tap plug 200 is connected to the socket, and the other end is connected to the cable 400, ensuring a stable electrical connection between the cable 400 and the socket, reducing the risk of poor contact, and enhancing the reliability of power transmission. The sealing cap 300 is movably disposed on the socket 140 , which effectively insulates and protects the socket 140 , prevents external pollutants from entering the socket 140 , reduces the risk of electrical short circuit and leakage, and improves the safety and durability of the device.

[0036] In some embodiments, the socket includes a two-way socket 110, a three-way socket 120 and a four-way socket 130. The two-way socket 110 is provided with two sockets 140, and the three-way socket 120 and the four-way socket 130 are respectively provided with three sockets 140 and four sockets 140. The socket is provided with a shell 180, and the shell 180 is used to fix the socket on the pole. Different types of sockets provide a variety of options, and the appropriate socket can be selected according to actual needs. For application scenarios that require the connection of different numbers of cables 400, by providing a preset number of sockets 140, the installation process can be simplified and complex connection adjustments on site can be avoided. Multi-way sockets allow different numbers of taps to be achieved at the same cable 400 tapping point, thereby meeting the needs of power networks of different sizes. Using a tap with a preset number of sockets 140 can reduce the need for customization and additional accessories, thereby reducing overall costs and simplifying maintenance and management.

[0037] In some embodiments, the socket 140 has a plugged state and a sealed state. When the tap plug 200 is inserted into the socket 140, the socket 140 is in the plugged state; when the sealing cap 300 is inserted into the socket 140, the socket 140 is switched to the sealed state. When the plug of the tap plug 200 or the plug of the cable 400 is inserted into the socket 140, the socket 140 is in the plugged state, and the connection contacts inside the socket 140 are in contact with the plug of the tap plug 200 to establish an electrical connection to achieve the tapping of the cable 400. The structure inside the socket 140 ensures stable contact between the plug and the socket 140, and ensures stable current transmission. When the plug is unplugged or not connected, the sealing cap 300 is inserted into the socket 140, and the socket 140 is switched to the sealed state. The sealing cap 300 fills the gap in the socket 140 to form a sealed protection. The sealed state effectively prevents the intrusion of external pollutants such as moisture, dust, and chemicals, and protects the electrical contact points inside the socket 140. The sealed state provides automatic protection for the unconnected socket 140, avoiding corrosion or other damage that may be caused by the socket 140 being exposed to the environment. When the socket 140 is in a sealed state, the impact of external pollution on the socket 140 can be effectively reduced, thereby improving the service life and reliability of the equipment. Switching to a sealed state when the socket 140 is not connected can reduce the risk of electric shock. The sealing cap 300 provides insulation protection, avoids the risk of accidental touching or contacting live parts, and helps prevent the electrical components inside the socket 140 from being affected by short circuits, leakage and other problems, thereby improving the safety of the system. When the user is performing maintenance or replacing the cable 400, it is very convenient to switch to the plug-in state without the need for additional sealing tools or procedures. The sealing cap 300 can also be easily replaced or repaired to ensure the durability and effectiveness of the sealing function. In different usage environments, the socket 140 can switch states according to actual needs and provide flexible adaptability.

[0038] In some embodiments, the overhead cable 400 tap also includes a first locking device, the first locking device includes a threaded portion 141 and a threaded matching portion 210, the threaded portion 141 is arranged at the socket 140, and the threaded matching portion 210 is arranged on the tap plug 200, and when the tap plug 200 is inserted into the socket 140, the threaded portion 141 and the threaded matching portion 210 are connected. The threaded portion 141 and the threaded matching portion 210 ensure that the tap plug 200 can be tightly locked when inserted into the socket 140. Rotating the tap plug 200 will cause the threaded matching portion 210 to be tightly engaged with the threaded portion 141, ensuring the firmness of the connection and avoiding loosening or accidental falling off. The installation process is simplified by threaded operation. The user only needs to rotate the tap plug 200 to complete the connection, without additional tools or complicated operating steps, which improves the convenience of installation. Tight threaded connection can effectively prevent poor contact, reduce the risk of leakage, and ensure the safety and stability of the power system. The cooperation between the threaded portion 141 and the threaded mating portion 210 can help automatically align the tap plug 200 with the socket 140, reducing the problem of poor contact caused by misalignment. The threaded connection can also enhance the sealing performance, further preventing moisture, dust or other contaminants from entering the socket 140, thereby improving overall durability. When disassembly or maintenance is required, the user can easily disassemble the tap plug 200 by simply rotating it counterclockwise, simplifying the maintenance and replacement process. The threaded connection increases mechanical strength and stability, can withstand greater physical pressure and vibration, and adapt to harsh environmental conditions.

[0039] In some embodiments, the overhead cable 400 tap also includes a second locking device, which includes a sliding sleeve 150 and a limiting bead 160. A limiting groove 151 is provided on the sliding sleeve 150. The sliding sleeve 150 drives the limiting bead 160 to enter the limiting groove 151, and the second locking device is in an unlocked state. A reset spring 170 is also provided on one side of the sliding sleeve 150. When the tap plug 200 extends into the socket 140 when the second locking device is in an unlocked state, the reset spring 170 drives the sliding sleeve 150 to reset, and the second locking device switches to a locked state. In the unlocked state, the limiting groove 151 of the sliding sleeve 150 is aligned with the limiting bead 160, allowing the tap plug 200 to be freely inserted into the socket 140. At this time, the limiting bead 160 is pushed into the limiting groove 151 by the sliding sleeve 150, ensuring that the tap plug 200 can smoothly enter and dock with the socket 140. When the tap plug 200 is inserted into the socket 140, the return spring 170 will automatically work to push the sliding sleeve 150 back to the original position, so that the limiting bead 160 is pushed out from the limiting groove 151, thereby locking the tap plug 200. The limiting bead 160 and the limiting groove 151 provide a firm locking mechanism to ensure the stability of the tap plug 200 in the socket 140 and avoid accidental falling off due to vibration or pressure. When the tap plug 200 needs to be disassembled, the sliding sleeve 150 only needs to be pushed to the unlocked state, and the limiting bead 160 can be easily pulled out of the limiting groove 151. The return spring 170 ensures a smooth disassembly process.

[0040] In some embodiments, the overhead cable 400 tap also includes an electrical connection device, which includes a terminal 220 and a conductive rod 230. The terminal 220 and the conductive rod 230 are arranged in the tap plug 200, one end of the terminal 220 is fixed to the cable 400, and the other end of the terminal 220 is threadedly connected to the conductive rod 230. The terminal 220 supports the connection of different types of cables 400, such as round or flat cables 400, which improves the applicability of the tap. In the tap plug 200, insulating materials are added to cover the terminal 220 and the conductive rod 230 to enhance electrical safety and prevent short circuits and electric shock risks. The threaded connection provides additional mechanical fixing force, which helps to withstand vibration and mechanical shock and prevent the cable 400 from loosening. The stable connection ensures good conduction of current and reduces resistance and energy loss.

[0041] In some embodiments, the cable 400 includes a core 410. When the cable 400 and the tap plug 200 are plugged in, the core 410 of the cable 400 extends into the terminal 220 and is electrically connected to the conductive rod 230. The core 410 of the cable 400 is connected to the terminal 220 in the plugged in state, and is electrically connected to the conductor or other electrical components inside the cable 400 through the conductive rod 230. In order to enhance the stability of the connection and reduce electrical interference, to ensure good contact between the core 410 and the terminal 220, and to prevent loosening during operation or environmental changes. In addition, the materials of the cable 400 and the tap plug 200 can be selected from insulating and heat-resistant materials.

[0042] In some embodiments, the sealing cap 300 includes a first connector 310 and a second connector 320, wherein the first connector 310 is used to connect the sealing cap 300 to the socket, and the second connector 320 is threadedly connected to the first connector 310. High-performance sealing materials such as silicone, fluororubber or EPDM are used to improve the temperature resistance and chemical resistance of the sealing cap 300 to ensure waterproof and dustproof effects. The threaded connection uses anti-loosening threads or double-start threads to enhance the stability and durability of the connection. At the same time, locking washers or locking glue are added to prevent the threaded connection from loosening under vibration or temperature changes. Anti-corrosion coatings are applied to threaded connection parts to improve environmental resistance and extend service life. Anti-ultraviolet coatings are added to the sealing cap 300 to prevent aging and deterioration of the material due to sunlight. The threaded connection is a self-aligning threaded connection, which simplifies the installation process and is equipped with markings or instructions to ensure correct docking.

[0043] In some embodiments, the sealing cap 300 further includes an inner shield 330, an insulating layer 350 and an outer shield 340. The insulating layer 350 is disposed between the inner shield 330 and the outer shield 340, and the insulating layer 350 is injection molded. The inner shield 330 uses conductive EPDM, the insulating layer 350 uses insulating EPDM, and the outer shield 340 uses conductive EPDM.

[0044] In some embodiments, the tap plug 200 is provided with a tap interface 270, and the sealing cap 300 is provided with a sealing opening 360, and the tap interface 270 and the sealing opening 360 are both adapted to the shape of the socket 140. The tap interface 270 and the sealing opening 360 can be precisely docked when inserted to reduce installation errors. Materials suitable for high or low temperature environments are selected to ensure that the tap plug 200 and the sealing cap 300 can maintain good sealing properties even under extreme temperature conditions.

[0045] Workflow:

[0046] When installing the socket on the electric pole, you must first ensure the safety of the operation and wear protective equipment. Then, use a special fixing fixture to firmly install the socket at the predetermined position of the electric pole to ensure that it will neither loosen nor shake, nor pose a safety hazard to passers-by. Subsequently, accurately dock one end of the tap plug 200 into the socket 140 of the socket, and use special tools to tighten the connection to ensure stable and efficient power transmission. For the connection between the other end of the tap plug 200 and the connecting cable 400, a strict electrical connection and mechanical fixation are performed to prevent poor contact or falling off. For the tap plug 200 socket 140 that is not connected temporarily, in order to avoid the intrusion of external factors such as dust and moisture, a sealing cap 300 is used for sealing. The sealing cap 300 can effectively isolate the external environment and protect the internal electrical components from damage, thereby extending the service life and safety of the entire electrical system.
