[0002] With the rapid development of the power industry, the stable operation of the power system has put forward higher requirements on the performance of power fittings. Power fittings are mainly used to connect, fix and protect key components such as cables and wires to ensure the normal operation of the power system. As an indispensable part of the power system, the stability and reliability of power fittings are of great significance to ensuring the safety of the power grid and improving the efficiency of power transmission.

[0003] However, in actual applications, due to environmental factors, equipment aging or improper installation, electrical fittings may become loose, resulting in poor contact, increased resistance, heat generation and even safety accidents. Therefore, it is particularly important to design an anti-loosening electrical fitting. Summary of the invention

[0012] Preferably, the top surface of the fixing ring is provided with a ring groove which is small outside and large inside, and the bottom surface of the nut is provided with a positioning ring which is the same size and shape as the ring groove.

[0013] Preferably, four auxiliary columns are arranged on the side wall of the nut along its circumference.

[0014] A method for using an anti-loosening energy-saving electrical hardware comprises the following steps: Step S1: removing the insulation skins at the ends of the two wires to be connected to expose the multiple conductive cores inside, and inserting the conductive cores of the two wires into the two wire slots from both ends respectively; Step S2: Turn to the nut, so that the stud drives the pressure plate to move downward, so that the pressure plate presses on the conductive wire core, and the spring is compressed at the same time; Step S3: Continue to rotate the nut to make the conductive wire core fully contact with the inside of the wire slot until the conductive wire core is completely pressed by the pressing plate; Step S4: Turn the bolt downward so that the clamping block under the stud presses the top surface of the nut to prevent the nut from rotating accidentally.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are: 1.

During the installation process, the conductive wire core is inserted into the wavy wire trough and fixed by the wavy pressure plate. During this process, the spring is compressed to provide additional reaction force to prevent the nut from loosening and ensure good electrical contact.

[0016] 2. The present invention can prevent the nut from loosening due to long-term use or external force by arranging a bolt above the nut. When the pressure plate fixes the wire in place, by rotating the bolt, the clamping block at the bottom directly acts on the top of the nut, applying additional downward pressure to prevent the nut from accidentally rotating and improve the anti-loosening effect.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figures 1 to 5 , an anti-loosening energy-saving electric hardware embodiment provided by the present invention: an anti-loosening energy-saving electric hardware, comprising a fixing seat 1, two wire grooves 2 are arranged on the fixing seat 1 at intervals, the inner side of the wire groove 2 is a wavy structure, a pressure plate 3 is arranged above the wire groove 2, and the bottom surface of the pressure plate 3 is a wavy structure, spring grooves 4 are arranged on both sides of the wire groove 2 inside the fixing seat 1, a plurality of springs 5 ​​are arranged in the spring groove 4, and the two ends of the spring 5 are respectively connected to the inner bottom surface of the spring groove 4 and the bottom surface of the pressure plate 3, a cover plate 6 is arranged on the fixing seat 1 above the pressure plate 3, a first through hole 7 is arranged on the cover plate 6, a fixing ring 8 is arranged on the cover plate 6 above the first through hole 7, a nut 9 is rotatably connected to the fixing ring 8, and a stud 10 passing through the first through hole 7 and the nut 9 is arranged on the pressure plate 3.

[0021] The design of the wavy wire trough 2 and the pressure plate 3 significantly increases the contact area between the wire and the power fittings, optimizes the stability of the electrical connection, avoids the increase in resistance caused by poor contact, and thus reduces the loss of electric energy during transmission. During the installation process, the conductive wire core is inserted into the wavy wire trough 2 and fixed by the wavy pressure plate 3. During this process, the spring 5 is compressed to provide additional reaction force to prevent the nut from loosening and ensure good electrical contact. This design not only enhances the reliability and durability of the connection, but also, due to the elastic effect of the spring 5, it can effectively absorb and buffer small movements or vibrations caused by environmental factors, reduce stress concentration, and thus extend the service life of the wires and fittings.

[0022] The present invention is applicable to the case where multiple conductive cores are arranged in a single electric wire. The depth of the trough of the wave-shaped structure of the wire slot 2 and the pressure plate 3 is smaller than the radius of the conductive core, ensuring that the conductive core will not fall into the trough and can be effectively compressed.

[0023] Furthermore, a slide rail 11 is provided on the inner wall of the spring groove 4 along the height direction, and slide grooves 12 are provided at both ends of the pressure plate 3, which ensures the precise guidance of the pressure plate 3 when moving up and down, prevents deviation caused by friction or lateral force, and thus improves the stability and reliability of the structure.

[0024] Furthermore, a plurality of telescopic rods 13 are arranged in the spring groove 4, and the two ends of the telescopic rods 13 are respectively connected to the inner bottom surface of the spring groove 4 and the bottom surface of the pressure plate 3, and the telescopic rods 13 and the spring 5 are cross-arranged. The existence of the telescopic rods 13 provides additional support for the pressure plate 3, thereby enhancing the rigidity of the overall structure.

[0025] Furthermore, second through holes 14 are arranged on both sides of the first through hole 7 on the cover plate 6, a guide tube 15 is arranged on the cover plate 6 above the second through hole 14, and a movable column 16 passing through the second through hole 14 and the guide tube 15 is arranged on the pressure plate 3. The movement of the movable column 16 is guided by the guide tube 15, so that the smooth movement of the movable column 16 in the vertical direction can be ensured, and additional stress caused by tilting or offset can be avoided.

[0026] Furthermore, a connecting plate 17 is provided on the top of the moving column 16 and the stud 10, and the connecting plate 17 fixes the moving column 16 and the stud 10 together to form a whole, thereby enhancing the stability of the structure. This design enables the stud 10 to drive the moving column 16 to move synchronously when moving, thereby ensuring the tightness of the wire connection.

[0027] Furthermore, threaded holes 18 are provided on both sides of the stud 10 on the connecting plate 17, bolts 19 are provided in the threaded holes 18, and a clamping block 20 is provided on the bottom surface of the bolt 19. The bottom surface of the clamping block 20 is pressed on the top surface of the nut 9, which can apply additional pressure to the nut 9 to prevent it from loosening due to vibration or other external factors, thereby improving the anti-loosening effect.

[0028] Furthermore, the top surface of the fixing ring 8 is provided with a ring groove 21 which is small outside and large inside, and the bottom surface of the nut 9 is provided with a positioning ring 22 which is the same size and shape as the ring groove 21, ensuring the correct position of the nut 9 on the fixing ring 8 so that the nut 9 can only rotate but cannot move up and down.

[0029] Furthermore, four auxiliary columns 23 are arranged on the side wall of the nut 9 along its circumference. When the nut 9 is rotated, the auxiliary columns 23 provide force, making it easier to rotate the nut 9.

[0030] A method for using an anti-loosening energy-saving electrical hardware comprises the following steps: Step S1: remove the insulation skins at the ends of the two wires to be connected to expose the multiple conductive cores inside, and insert the conductive cores of the two wires into the two wire slots 2 from both ends respectively; Step S2: Turn to the nut 9, so that the stud 10 drives the pressure plate 3 to move downward, so that the pressure plate 3 is pressed on the conductive wire core, and the spring 5 is compressed at the same time; Step S3: Continue to rotate the nut 9 to make the conductive wire core fully contact with the inside of the wire slot 2 until the conductive wire core is completely pressed by the pressing plate 3; Step S4: Turn the bolt 19 downward so that the clamping block 20 below the bolt 19 presses the top surface of the nut 9 to prevent the nut 9 from rotating accidentally.
