Description

[0002] As is well known, in many fields such as industrial production, building electrical systems, and household appliances, wiring devices are key components for circuit connections, and their performance directly affects the safe and stable operation of the entire circuit system. However, the traditional wiring devices widely used today have revealed many undeniable defects in practical applications. Traditional wiring devices mostly rely on screws to directly tighten the wiring or simple clip-on structures. This method of fixing has very limited coverage of the wiring, often only effective for a localized area. When used in environments with continuous vibration, such as factory production lines or vehicle electrical systems, the wiring can easily loosen under the influence of vibration. In scenarios requiring frequent movement or subject to external pulling forces, such as temporary outdoor circuits or frequently moved small appliances, the probability of wiring loosening increases significantly. Once the wiring loosens, it leads to poor circuit contact, causing intermittent equipment operation and affecting production or usage efficiency, or even serious malfunctions such as arcing and short circuits. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0014] 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.
[0015] Please see Figures 1-4This utility model relates to a wiring device for a DC power supply, comprising a junction box 1. A wiring groove is formed on one side of the junction box 1, and a fixing groove is formed on one side of the wiring groove. A fixing plate 2 and a lifting plate 3 are provided on the wiring groove. A guide mechanism is provided between the lifting plate 3 and the wiring groove. A wedge 4 is provided at the top of the lifting plate 3, and the lifting plate 3 extends into the fixing groove. A terminal 5 is provided at the bottom of the fixing groove. A threaded hole is formed between the other side of the junction box 1 and the wiring groove. A threaded post 6 is provided on the threaded hole, and a cone is provided at one end of the threaded post 6. 7. An angle locking mechanism is provided between the junction box 1 and the threaded post 6. A wire clamping mechanism is provided on the wiring groove. The wire clamping mechanism includes a semi-circular groove 8, a positioning hole, a positioning post 9, and an arc groove. The arc groove is opened on one side of the fixed groove. The positioning post 9 is installed at the bottom end of the fixed groove. The positioning hole is opened on the lifting plate 3. The semi-circular groove 8 is opened at the top end of the fixed plate 2 and the bottom end of the lifting plate 3. Multiple wire clamping mechanisms are provided. In this embodiment, in the wire clamping mechanism, the wire end passes through the arc groove and then wraps around the positioning post 9. The outer side is used for initial positioning and connection to terminal 5. At this time, the wire abuts against the semi-circular groove 8 of the fixing plate 2. Multiple wire clamping mechanisms facilitate the connection of multiple wires to terminal 5. Then, by pushing the lifting plate 3 downward, the semi-circular groove 8 of the lifting plate 3 abuts against the wire, thereby clamping and fixing the wire. Then, rotate the threaded post 6 on the threaded hole. The cone 7 at its end will contact the inclined block 4 at the top of the lifting plate 3. As the threaded post 6 is pushed forward, the cone 7 is driven by the inclined surface of the inclined block 4, pushing the lifting plate 3 to move downward along the guide mechanism in the wire groove until the lifting plate 3 extends into the fixing groove and cooperates with terminal 5, completing the initial fixing of the wire. The angle locking mechanism locks the angle after the threaded post 6 is adjusted into place, preventing it from shifting due to external force during subsequent operation or use, and ensuring that the pressure of the cone 7 on the lifting plate 3 remains stable. Through the mechanical transmission of the threaded post 6, the cone head 7, and the lifting plate 3, along with the enveloping fixation of the wire clamping mechanism, the wiring can be effectively prevented from loosening or falling off under external forces such as vibration and pulling, ensuring the continuity and reliability of the circuit connection. The entire wiring process can be completed by rotating the threaded post 6 to drive the lifting plate 3 to complete the fixing action, without the need for complicated tools or steps, simplifying the wiring operation process, improving installation and maintenance efficiency, and the guiding mechanism ensures the precise movement trajectory of the lifting plate 3.
[0016] To facilitate locking the angle of the threaded post 6, the angle locking mechanism in this design includes an annular groove and a fastening groove. The annular groove is located on the outer side of the threaded post 6 and has an iron toothed ring 10. The fastening groove is located inside the junction box 1 and connects to the threaded hole. The fastening groove has a magnetic toothed block 11 that abuts against the iron toothed ring 10. A slot is formed between the fastening groove and the outer side of the junction box 1. A push plate 12 is provided between the magnetic toothed block 11 and the slot. By utilizing the magnetic engagement between the iron toothed ring 10 and the magnetic toothed block 11, the push plate 12 controls the separation and engagement of the magnetic toothed block 11 and the toothed ring, thereby locking the rotation angle of the threaded post 6. This prevents the threaded post 6 from shifting its angle due to vibration or external force during wiring, ensuring stable pressure of the cone 7 on the lifting plate 3 and improving the reliability of the wiring structure. In use, pushing the push plate 12 on the slot allows the magnetic toothed block 11 to leave the toothed ring, facilitating the rotation of the threaded post 6.
[0017] To ensure stable linear movement of the lifting plate 3, the guiding mechanism in this design includes a guide bar 13 and a guide groove. The guide bar 13 is installed on one side of the inner wall of the fixed groove, and the guide groove is formed on one side of the lifting plate 3. The guide bar 13 passes through the guide groove, and the guide bar 13 slides in conjunction with the guide groove to restrict the movement trajectory of the lifting plate 3, ensuring that it only moves vertically. This prevents the lifting plate 3 from tilting or deviating under force, ensuring precise contact between the inclined block 4 and the cone head 7, and ensuring the stability of the lifting action. Two guiding mechanisms are provided and symmetrically arranged. Both the guide bar 13 and the guide groove have a T-shaped structure. The symmetrical guiding structure on both sides forms a balanced constraint, distributing the force on the lifting plate 3. Furthermore, the T-shaped guide bar 13 and guide groove further enhance the lifting plate 3's resistance to eccentric loads.
[0018] To meet the insulation requirements of electrical equipment, the junction box 1 in this design is made of ABS engineering plastic. ABS engineering plastic possesses insulation and mechanical strength, and the addition of flame retardants improves its high-temperature resistance and fire resistance. This reduces the risk of fire caused by short circuits or high temperatures, thus enhancing the safety of the device.
[0019] To prevent the circuit from becoming loose or slipping, in this design, the inner wall of the semi-circular groove 8 is provided with a rubber pad, and the surface of the rubber pad is provided with anti-slip texture. The elastic deformation of the rubber pad can fit the circuit with different diameters, and the anti-slip texture increases the friction to prevent the circuit from becoming loose or slipping.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
