They are a type of power transmission line used to transmit electrical energy. When transmitting power over long distances, overhead lines are required. The poles and towers support the overhead lines at a certain height, which can achieve efficient long-distance power transmission without affecting normal traffic on the ground.

[0003] In actual use, the lack of a convenient connection structure between two sections of overhead lines makes the connection process very troublesome, which is not conducive to the continuous construction and use of overhead lines and affects the efficiency of their connection. Utility Model Content

[0004] This utility model provides an overhead line that is easy to connect, which can effectively solve the problem mentioned in the background art that the connection process of the current overhead line is very troublesome when it is actually erected and used, due to the lack of a convenient connection structure between two sections of the overhead line, which is not conducive to the continuous erection and use of the overhead line and affects its connection and use efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overhead line that is easy to connect, comprising a copper wire conductor, the outer side of which is tightly covered with an inner sheath, and the outer side of which is tightly covered with a tin-plated layer, the outer side of which is connected to an outer sheath by a sleeve, the connecting part of the copper wire conductor is connected by two connectors, the edge of the connectors is connected with several sets of adhesive tape at equal angles along the spiral direction, the edge of the connector at one end of the copper wire conductor is provided with a plug seat, the edge of the connector at the other end of the copper wire conductor is provided with a plug connector, and the edge of the plug seat is provided with a sealing plate corresponding to the plug connector.

[0006] The plug has three sets of snap-fit ​​grooves along its circumferential direction. Each snap-fit ​​groove on the side of the plug is connected to a limit box. A snap-fit ​​spring is embedded in the inner side of the limit box. A movable rod is slidably connected to the inner side of the limit box. A pull block is fixedly connected to the top of the movable rod, and a snap-fit ​​block is connected to the bottom of the movable rod.

[0007] The top and bottom of the connector are both fixedly connected to a connecting seat, and the connecting seats on the two connectors are connected and fixed together by a tensioning screw.

[0008] Preferably, the inner side of the adhesive tape is provided with an adhesive strip, and the adhesive tape is tightly wrapped around the outer side of the outer sheath in a spiral manner.

[0009] Preferably, after the connector is fully inserted into the socket, an electrical connection is completed between the two overhead lines, and the sealing plate at the edge of the socket is in close contact with the end of the connector.

[0010] Preferably, the top end of the snap-fit ​​spring is connected to the top wall of the limiting box, and the bottom end of the snap-fit ​​spring is connected to the top of the snap-fit ​​block. The snap-fit ​​block slides along the limiting box, and a slanted groove is provided on the bottom edge of the snap-fit ​​block.

[0011] Preferably, the inner side edge of the inner sheath is provided with arc-shaped grooves at equal angles, and a matching arc groove is provided between two adjacent arc-shaped grooves.

[0013] Preferably, the gas groove is connected to the interior of the storage chamber through the groove, and the interior of the storage chamber is supported by a heat-conducting metal sheet.

[0014] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0015] 1. The connector, socket, and plug allow for quick and easy connection of two sections of overhead cable. The limiting box, snap-fit ​​spring, movable rod, pull block, and snap-fit ​​block enable the snap-fit ​​block to retract into the limiting box when the plug is inserted into the socket. When the snap-fit ​​groove on the plug moves to the corresponding position, the snap-fit ​​spring's elasticity allows the snap-fit ​​block to quickly snap into the groove. This achieves rapid snap-fit ​​limiting between the plug and socket, making operation convenient. Limiting is achieved during the insertion process between the plug and socket, improving the ease of connecting overhead cables.

[0016] Furthermore, the locking block is actively moved by using a pull block and a movable rod, which facilitates the release of the locking block from the locking slot, thereby facilitating the disassembly of the connector and the socket.

[0017] 2. By spirally wrapping the adhesive tape at the end of the connector around the outside of the overhead cable, a tight connection between the connector and the overhead cable is achieved, preventing tensile breakage due to bending. Furthermore, the connector and tensioning screw on the connector head can be used to fix the connection between the connector and the plug, and to further strengthen the connection when the overhead cable is long, thus ensuring that the connector and the plug will not break during long-distance use.

[0018] 3. Through the squeezing and restraining effect of the arc-shaped groove and the matching arc groove, multiple groups of copper wire conductors can be more tightly and stably concentrated into a wire bundle, so that the internal copper wire conductors of the overhead cable will not become loose or twisted during use.

[0019] By utilizing the through-slots inside the arc-shaped trough, when the temperature inside the overhead cable is high, heat can be actively dissipated by passing through the through-slots and air slots into the storage chamber. This increases the space for heat distribution, reduces the overall temperature inside the overhead cable, and facilitates further heat dissipation using heat-conducting metal sheets. This improves the effectiveness of active heat dissipation inside the overhead cable and helps maintain stable operation inside the overhead cable. Attached Figure Description

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1-5 As shown, this utility model provides a technical solution for an overhead line that is easy to connect, including a copper wire conductor 1. The outer side of the copper wire conductor 1 is tightly covered with an inner sheath 2, which is made of plastic. The outer side of the inner sheath 2 is tightly covered with a tin-plated layer 3. An outer sheath 4, made of polyethylene, is connected to the outer side of the tin-plated layer 3 by a sleeve connection. The connecting part of the copper wire conductor 1 is connected by two connectors 5. Several sets of adhesive tape 6 are connected at equal angles along the spiral direction on the edge of the connectors 5. A connector 5 at one end of a connector is provided with a plug 7 on its side, and a connector 8 at the other end of a connector 5 of the copper wire conductor 1 is provided with a plug 8 on its side. A sealing plate 15 is provided on the side of the plug 7 corresponding to the plug 8. After the plug 8 is fully inserted into the plug 7, the two sections of overhead line are electrically connected. Furthermore, the sealing plate 15 on the side of the plug 7 is in close contact with the end of the plug 8, so that the contact position of the end face between the plug 7 and the plug 8 has a higher tightness after connection.

[0030] The edge of the connector 8 is provided with three sets of snap-fit ​​grooves 9 along the circumferential direction. The edge of the connector 7 is connected to the snap-fit ​​grooves 9. The snap-fit ​​spring 11 is embedded in the inner side of the snap-fit ​​box 10. The inner side of the snap-fit ​​box 10 is slidably connected to the movable rod 12. The top end of the movable rod 12 is fixedly connected to the pull block 13, and the bottom end of the movable rod 12 is connected to the snap-fit ​​block 14. The top end of the snap-fit ​​spring 11 is connected to the top wall of the snap-fit ​​box 10, and the bottom end of the snap-fit ​​spring 11 is connected to the top of the snap-fit ​​block 14. The snap-fit ​​block 14 slides along the snap-fit ​​box 10. The bottom edge of the snap-fit ​​block 14 is provided with a slanted groove. When the snap-fit ​​groove 9 on the connector 8 moves to the position corresponding to the snap-fit ​​block 14, the snap-fit ​​spring 11 is used to return to its original position, so that the snap-fit ​​block 14 can quickly snap into the snap-fit ​​groove 9.

[0031] Connecting seats 16 are fixedly connected to the top and bottom middle of the connector 5, and the connecting seats 16 on the two connectors 5 are connected and fixed together by a tensioning screw 17.

[0032] The inner side of the adhesive tape 6 is provided with an adhesive strip, and the adhesive tape 6 is tightly wrapped around the outer side of the outer sheath 4 in a spiral manner. By wrapping the adhesive tape 6 around the outer side of the overhead cable in a spiral manner, the connection between the connector 5 and the overhead cable is made tight, and the phenomenon of stretching and breaking due to bending is avoided.

[0033] The inner side edge of the inner sheath 2 is provided with arc-shaped grooves 18 at equal angles, and a matching arc groove 19 is provided between two adjacent arc-shaped grooves 18.

[0034] The arc-shaped groove 18 has a through groove 20 evenly distributed inside. The inner side of the inner sheath 2 has an air groove 21 evenly distributed at the through groove 20. The inner side of the inner sheath 2 has an accumulation chamber 22, and the inner side of the accumulation chamber 22 is evenly provided with a heat-conducting metal sheet 23. The air groove 21 connects the through groove 20 and the inside of the accumulation chamber 22. The inner cavity of the accumulation chamber 22 is supported by the heat-conducting metal sheet 23. When the temperature inside the overhead cable is high, the heat can be actively dissipated so that the heat enters the accumulation chamber 22 through the through groove 20 and the air groove 21, thereby increasing the space for heat distribution and reducing the overall temperature inside the overhead cable.

[0035] The working principle and usage process of this utility model: In the actual connection process, the overhead line that is easy to connect firstly connects the two ends of the overhead line with connectors 5 respectively, and then uses the plug-in sockets 7 and plug-in connectors 8 at the ends of the two connectors 5 to quickly connect the two overhead lines and realize the transmission of electrical energy between the two overhead lines. Furthermore, the adhesive tape 6 set at the end of the connector 5 is used to wrap the adhesive tape 6 around the outside of the overhead cable in a spiral manner, so as to make the connection between the connector 5 and the overhead cable tighter and avoid the phenomenon of tensile breakage due to bending.

[0036] When two sections of overhead lines need to be combined and connected, the two sections of overhead cables are quickly combined and connected by the plug socket 7 and the plug connector 8. When the plug connector 8 is inserted into the plug socket 7, the plug connector 8 presses the inclined surface of the snap-fit ​​block 14, causing the snap-fit ​​block 14 to retract into the limiting box 10. When the snap-fit ​​groove 9 on the plug connector 8 moves to the position corresponding to the snap-fit ​​block 14, the snap-fit ​​spring 11 is used to elastically reset, so that the snap-fit ​​block 14 can quickly snap into the snap-fit ​​groove 9, thereby realizing the snap-fit ​​limiting between the plug connector 8 and the plug socket 7.

[0037] Based on the initial connection and limiting of the connector 8 and the connector 7, the connector 16 and the tensioning screw 17 on the connector 5 can be used to connect and fix the connector 7 and the connector 8. When the length of the overhead cable is long, the connection between the connector 7 and the connector 8 can be further strengthened to ensure that the connector 7 and the connector 8 will not break during long-distance use. In addition, when it is necessary to disassemble the two sections of the overhead line separately, the tensioning screw 17 is loosened first, and then the locking block 14 is pulled by the pull block 13 and the movable rod 12 to move actively, so as to release the limiting between the locking block 14 and the locking groove 9, and thus facilitate the disassembly between the connector 8 and the connector 7.

[0038] During the use of overhead cables, the inner sheath 2, the tin-plated layer 3 and the outer sheath 4 are used to shield and protect the copper wire conductor 1. Furthermore, through the squeezing and restraining effect of the arc-shaped groove block 18 and the matching arc groove 19 on the outside of the copper wire conductor 1, multiple sets of copper wire conductors 1 can be more tightly and stably bundled into wire bundles, so that the copper wire conductor 1 inside the overhead cable will not become loose or twisted during use.

[0039] When excessive heat occurs inside the overhead cable, the through groove 20 inside the arc-shaped groove block 18 can be used to actively dissipate heat by allowing the heat to enter the accumulation chamber 22 through the through groove 20 and the air groove 21. This increases the space for heat distribution, reduces the overall temperature inside the overhead cable, and the heat-conducting metal sheet 23 facilitates further heat dissipation, thus improving the effect of active heat dissipation inside the overhead cable.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
