[0001] This utility model relates to the field of electrical engineering circuit technology, specifically to a quick connection device for electrical engineering circuits. Background Technology

[0002] Electrical engineering is a branch of engineering that mainly studies the generation, transmission, distribution, control, and application of electrical energy, as well as the design and development of related equipment, systems, and technologies. Electrical engineering covers a wide range of fields, including power systems, electronic technology, communication technology, automation control, signal processing, and computer hardware. In the field of electrical engineering, line connection is a key link to ensure the normal operation of power systems. Traditional line connection methods usually use bolt fixing, welding, or plug-in methods.

[0003] Existing electrical engineering wiring connection devices typically use bolt fixing and welding connections, which are easily affected by environmental factors (such as temperature and humidity), leading to loosening or corrosion at the connection points, affecting the reliability and safety of the electrical connection. To address this, we propose a quick connection device for electrical engineering wiring. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing electrical engineering wiring connection devices typically use bolt fixing and welding connections, which are easily affected by environmental factors (such as temperature and humidity), leading to loosening or corrosion at the connection points, thus affecting the reliability and safety of the electrical connection.

[0005] To solve the above-mentioned technical problems, this application provides a quick connection device for electrical engineering circuits, including a protective shell, a top cover on the top of the protective shell, connecting pipes extending through both ends of the protective shell, a fastening pipe threaded to one end of the connecting pipe, and a fastening ring threaded to one end of the fastening pipe.

[0006] In some embodiments, the top of the protective shell has an upwardly protruding connection port, and the two ends of the connection port are provided with first slots. One end of the fastening tube has a telescopic groove, and one end of the telescopic groove is provided with a threaded extension plate. The fastening ring is fixed to one end of the fastening tube through the threaded extension plate.

[0007] In some embodiments, a fixing plate protrudes outward from the side of the top cover, and a rotating rod is rotatably connected inside the fixing plate. One end of the rotating rod extends outward in an arc shape, and a connecting rod is movably connected inside the other end of the rotating rod. A limiting rod is movably connected to one end of the connecting rod, and a positioning block protrudes outward from one end of the limiting rod.

[0008] In some embodiments, a limiting hole is formed in the inner wall of the top cover, a release groove is recessed inward in the middle of the positioning block, one end of the positioning block is engaged in the inside of the limiting hole, the other end of the positioning block is engaged in the inside of the first slot, and the diameter of the connecting part of the limiting rod and the connecting rod is the same as the diameter of the first slot.

[0009] In some embodiments, the curved end of the rotating rod has a magnetic clasp protruding inward, the inner side of the rotating rod is attached to the circumferential side of the upper cover, and the side of the upper cover has a groove and is connected to the magnetic clasp by magnetic attraction.

[0010] In some embodiments, a gap is provided between the threaded extension plates, and the connecting pipe, fastening pipe, fastening ring and the inner cavity of the protective shell are interconnected.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. This utility model involves inserting one end of each of two wires into the inner cavity of the protective shell through the inside of the fastening tube. After the connection is completed in the inner cavity of the protective shell, since the fastening ring is fitted onto the end of the fastening tube without a threaded structure, when the fastening ring is screwed towards one end, the gap between the threaded extension plates gradually tightens, fixing the wires inserted inside. Under the protection of the top cover set on the top of the protective shell, the connection is prevented from loosening or being corroded, thus improving the reliability and safety of the electrical connection.

[0013] 2. This utility model uses a positioning block at one end of a limiting rod and a connecting part at the other end to the connecting rod, which are engaged inside the first slot. Since the diameter of the positioning block is the same as the diameter of the first slot, when the rotating rod rotates around the connecting shaft between the inside of the fixed plate and the rotating rod, the end of the rotating rod inside the fixed plate brings out the connecting rod, pulling one end of the limiting rod away from the inside of the limiting hole. At the same time, the limiting rod is disengaged from the inside of the first slot through the release groove, allowing for quick disassembly between the protective shell and the top cover.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a quick connection device for electrical engineering circuits, including a protective shell 1, a top cover 5 on the top of the protective shell 1, connecting pipes 2 penetrating through both ends of the protective shell 1, a fastening pipe 3 threadedly connected to one end of the connecting pipe 2, and a fastening ring 4 threadedly connected to one end of the fastening pipe 3. The interior of the connecting pipe 2 and the fastening pipe 3 is used for the two ends of the wires to be connected to pass through, so that the two ends of the wires are placed in the inner cavity of the protective shell 1 for connection. The top cover 5 can seal the top of the protective shell 1 to prevent the connection from loosening or being corroded due to external reasons.

[0023] Please see Figure 1-3 The protective shell 1 has a connecting port 100 protruding upwards on its top. The two ends of the connecting port 100 are provided with first slots 101. One end of the fastening tube 3 has a telescopic groove 300. One end of the telescopic groove 300 is provided with a threaded extension plate 301. The fastening ring 4 is fixed to one end of the fastening tube 3 through the threaded extension plate 301. There is elasticity between the telescopic groove 300 and the threaded extension plate 301, which can make the wire pass through the inside more smoothly. When not in use, the fastening ring 4 is sleeved on the outside of the telescopic groove 300. When it is engaged with the threaded extension plate 301, it can tighten the threaded extension plate 301, fix the wire passing through the inside, increase the tensile force that the wire connection part can withstand, and avoid the external tensile force from affecting the connection part.

[0024] Please see Figure 2-5A fixing plate 500 protrudes outward from the side of the upper cover 5. A rotating rod 6 is rotatably connected inside the fixing plate 500. One end of the rotating rod 6 extends outward in an arc shape, and a connecting rod 7 is movably connected inside the other end of the rotating rod 6. A limiting rod 8 is movably connected to one end of the connecting rod 7. A positioning block 9 protrudes outward from one end of the limiting rod 8. A limiting hole 501 is opened on the inner wall of the upper cover 5. A release groove 900 is recessed inward in the middle of the positioning block 9. One end of the positioning block 9 is engaged inside the limiting hole 501, and the other end of the positioning block 9 is engaged inside the first slot 101. The diameter of the connecting part of the limiting rod 8 and the connecting rod 7 is the same as the diameter of the first slot 101. The two ends of the limiting rod 8 with the same diameter as the first slot 101 are... When the rotating rod 6 is attached to the circumferential side of the upper cover 5, the upper cover 5 is secured to the top of the protective shell 1 through the first slot 101. When the rotating rod 6 rotates around the inside of the fixed plate 500, it pulls the connecting rod 7 to rotate around one end of the limiting rod 8 and pulls it outward from the fixed plate 500. At the same time, it drives the positioning block 9 set at one end of the limiting rod 8 to move in the direction of the rotating rod 6. Since the diameter of the release groove 900 is smaller than the diameter of the first slot 101, one end of the limiting rod 8 can be released from the inside of the first slot 101. Similarly, after the connection between the limiting rod 8 and the connecting rod 7 moves to one end of the rotating rod 6, the limiting rod 8 completely disengages from the first slot 101 set at both ends of the connecting port 100, so that the upper cover 5 can be released from the top of the protective shell 1.

[0025] Please see Figure 1-5 The rotating rod 6 has an inwardly protruding magnetic buckle 600 at one end with an arc. The inner side of the rotating rod 6 is attached to the circumferential side of the upper cover 5. The side of the upper cover 5 has a groove and is connected to the magnetic buckle 600 by magnetic attraction. The magnetic buckle 600 can fix the rotating rod 6 to the circumferential side of the upper cover 5. There is a gap between the threaded extension plates 301 to reduce the resistance when the internal wires pass through. The connecting tube 2, fastening tube 3, fastening ring 4 and the inner cavity of the protective shell 1 are interconnected, which facilitates the connection of the two ends of the wires that need to be connected inside the protective shell 1.

[0026] Example 2: Please refer to Figure 6 This utility model provides a technical solution: a quick connection device for electrical engineering circuits, including a protective shell 1, a top cover 5 on the top of the protective shell 1, and fixing plates 500 at both ends of the top cover 5. A rotating rod 6 is movably connected inside the fixing plates 500. One end of the rotating rod 6 protrudes from the center of the top cover 5 with a locking block 601. The top of the protective shell 1 extends upward and protrudes outward to the surrounding area with a second locking groove 102. The locking block 601 can be locked into the bottom of the second locking groove 102 to fix the top cover 5 on the top of the protective shell 1. The two ends of the rotating rod 6 are fixed to the circumferential side of the top cover 5 by magnetic buckles 600. By rotating the rotating rod 6 at both ends, it is more convenient for the top cover 5 to detach from the top of the protective shell 1, and the manufacturing cost is lower.
