Description

Technical Field

[0001] This utility model relates to a stable and energy-saving splicing fitting. Background Technology

[0002] Connecting fittings, as an indispensable component of power systems, primarily function to establish a stable and efficient connection between two conductors. This connection must not only meet mechanical strength requirements but also ensure excellent electrical performance to guarantee the safety and efficiency of power transmission.

[0003] As a type of splicing hardware, parallel groove clamps not only need to withstand the weight and tension of the conductors, but also need to maintain a stable connection under various environmental conditions. However, traditional parallel groove clamps rely solely on bolts for fixing, a method that has some obvious shortcomings in long-term use.

[0004] Due to factors such as wind, vibration, and temperature changes, bolts may gradually loosen. Once the bolts loosen, the contact pressure between the conductor and the parallel groove clamp decreases, leading to an increase in contact resistance. This not only affects the stability and efficiency of power transmission but may also cause more serious consequences, such as conductor detachment. Utility Model Content

[0005] The main objective of this invention is to provide a stable and energy-saving connector to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A robust and energy-efficient splicing fitting includes an upper clamp and a lower clamp. The bottom surface of the upper clamp has two upper clamping grooves spaced apart, and the top surface of the lower clamp has a lower clamping groove corresponding to the position of the upper clamping grooves. An upper connecting plate and a lower connecting plate are respectively provided at both ends of the upper and lower clamps. Multiple springs are provided on the top surface of the lower connecting plate, and a pressure plate is provided above the multiple springs. A pressure plate groove is provided on the bottom surface of the upper connecting plate. Upper edge through holes and lower edge through holes are respectively provided on both sides of the springs on the upper and lower connecting plates, and edge bolts are provided in the upper edge through holes and lower edge through holes.

[0008] Preferably, two springs are provided, and the two springs are spaced apart on the top surface of the lower connecting plate.

[0009] Preferably, the spring is provided with a telescopic rod.

[0010] Preferably, the two ends of the telescopic rod are connected to the lower connecting plate and the pressure plate, respectively.

[0011] Preferably, an upper central through hole is provided between the two upper clamping slots, and a lower central through hole corresponding to the position of the upper central through hole is provided between the two lower clamping slots.

[0012] Preferably, there are two upper central through holes and two lower central through holes, with the two upper central through holes spaced apart on the upper connecting plate and the two lower central through holes spaced apart on the lower connecting plate.

[0013] Preferably, a center bolt is provided in the upper center through hole and the lower center through hole.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This invention, by incorporating a spring and pressure plate between the upper and lower clamping plates, provides additional pressure during bolt tightening, resulting in a tighter contact between the conductor and the clamping plates, increasing the tightening force, and preventing bolt loosening. This design helps reduce contact resistance, improves the efficiency and stability of power transmission, reduces safety hazards caused by loosening or detachment, and ensures the safe and stable operation of the power system. Furthermore, the spring mechanism absorbs energy when subjected to external vibration or impact, thereby improving the durability and fatigue resistance of the entire structure.

[0022] like Figures 1-4As shown, the energy-saving splicing fitting with a stable connection provided in this embodiment includes an upper clamping plate 1 and a lower clamping plate 2. The bottom surface of the upper clamping plate 1 is provided with two upper clamping grooves 3 at intervals. The top surface of the lower clamping plate 2 is provided with a lower clamping groove 4 corresponding to the position of the upper clamping grooves 3. The two ends of the upper clamping plate 1 and the lower clamping plate 2 are respectively provided with an upper connecting plate 5 and a lower connecting plate 6. The top surface of the lower connecting plate 6 is provided with multiple springs 7. A pressure plate 8 is provided above the multiple springs 7. The bottom surface of the upper connecting plate 5 is provided with a pressure plate groove 9. The upper connecting plate 5 and the lower connecting plate 6 are respectively provided with upper edge through holes 10 and lower edge through holes 11 on both sides of the springs 7. Edge bolts 12 are provided in the upper edge through holes 10 and lower edge through holes 11.

[0023] In use, place the wire between the upper clamp 1 and the lower clamp 2, align the upper clamp 1 and the lower clamp 2, place the pressure plate 8 in the pressure plate groove 9, and then tighten the edge bolt 12 to compress the spring 7, so that the wire is firmly fixed in the splice fitting. The spring 7 provides a reaction force to prevent the edge bolt 12 from loosening.

[0024] In this embodiment, as Figure 1 As shown, there are two springs 7, which are spaced apart on the top surface of the lower connecting plate 6, increasing the stability of the entire structure and enhancing the anti-loosening effect.

[0025] In this embodiment, as Figure 1 As shown, a telescopic rod 13 is provided inside the spring 7. The two ends of the telescopic rod 13 are connected to the lower connecting plate 6 and the pressure plate 8, respectively. The telescopic rod 13 can provide additional support when the spring 7 is compressed, thereby improving stability.

[0026] In this embodiment, as Figure 1 As shown, an upper central through hole 14 is provided between the two upper clamping slots 3, and a lower central through hole 15 corresponding to the position of the upper central through hole 14 is provided between the two lower clamping slots 4. A central bolt 16 is provided in the upper central through hole 14 and the lower central through hole 15. The central bolt 16 is not only used to fasten the upper clamping plate 1 and the lower clamping plate 2, but also to adjust the contact pressure between the wire and the upper clamping plate 1 and the lower clamping plate 2 by its fastening force, so as to ensure the stability of the connection and the electrical performance.

[0027] In this embodiment, as Figure 1 As shown, there are two upper central through holes 14 and two lower central through holes 15. The two upper central through holes 14 are spaced apart on the upper connecting plate 5, and the two lower central through holes 15 are spaced apart on the lower connecting plate 6, which further provides fastening force.

[0028] In summary, in this embodiment, by incorporating a spring 7 and a pressure plate 8 between the upper clamp 1 and the lower clamp 2, additional pressure is provided during bolt tightening, resulting in a tighter contact between the conductor and the upper and lower clamps 1 and 2, increasing the tightening force and preventing bolt loosening. This design helps reduce contact resistance, improves the efficiency and stability of power transmission, reduces safety hazards caused by loosening or detachment, and ensures the safe and stable operation of the power system. Furthermore, the spring 7 mechanism can absorb energy when subjected to external vibration or impact, thereby improving the durability and fatigue resistance of the entire structure.
