[0023] Please see Figure 1-6This utility model provides an embodiment of a wire connector assembly, including a support frame 1 and a protective shell 2.

Connected to the rack 5, each protective shell 2 on one side of the rack 5 has a first support shaft 7 installed inside. A first gear 8 is fitted onto the surface of each first support shaft 7, and the first gear 8 meshes with the rack 5. A second support shaft 9 is installed inside each protective shell 2 on one side of the first support shaft 7. A second gear 10 is fitted onto the surface of each second support shaft 9, and the second gear 10 meshes with the first gear 8. A movable frame 11 is installed on the surface of each second gear 10, and the movable frame 11 extends to the outside of the protective shell 2. The outer wall of the movable frame 11... Each of the components is equipped with a first clamping frame 13. Inside each first clamping frame 13 are three sets of equally spaced first threaded blocks 29. Inside each first threaded block 29 is a first threaded rod 14, which is threadedly connected to the first threaded block 29. Both ends of the first threaded rod 14 extend to the outside of the first threaded block 29. A first handle 15 is installed on the outer wall of each first threaded rod 14. At the end of each first threaded rod 14 away from the first handle 15, a first arc-shaped copper clamping block 16 is provided. Each of the first connecting sleeves 17 is installed on the outer wall of the support frame 11, and each of the first connecting sleeves 17 is movably connected to the first threaded rod 14. Each of the movable frames 11 has a first copper pressure block 12 installed inside, and each of the first copper pressure blocks 12 extends to the outside of the movable frame 11. Each of the first arc-shaped copper clamps 16 has a first copper braided wire 18 installed on the outer wall, and each of the first copper braided wires 18 extends to the inside of the movable frame 11 and connects to the first copper pressure block 12. Each of the two ends of the support frame 1 has a second bolt 28 symmetrically installed, and each of the second bolts 28 extends to the outside of the support frame 1.

[0024] In use, the support frame 1 is first fixed inside the distribution box by the second bolt 28. The pressing block 6 is manually pressed, which drives the rack 5 to move. Under the meshing action of the rack 5 and the first gear 8, the rack 5 drives the first gear 8 to rotate. Under the meshing action of the first gear 8 and the second gear 10, the first gear 8 drives the second gear 10 to rotate. The second gear 10 drives the movable frame 11 to rotate. The movable frame 11 drives the first copper pressure block 12 to rotate, so as to facilitate the change from the contact state to the separation state between the first copper pressure block 12 and the second copper pressure block 21. A set of wires is placed between multiple sets of first arc-shaped copper clamps 16 inside the first clamping frame 13. By rotating the first handle 15, the first threaded rod 14 is driven to rotate. Under the thread support of the first threaded rod 14 and the first threaded block 29, the first threaded rod 14 moves inside the first threaded block 29. The first threaded rod 14 drives the first arc-shaped copper clamp 16 to move through the first connecting sleeve 17, so as to facilitate the movable clamping and fixing of the wire by multiple sets of first arc-shaped copper clamps 16. The first copper braided wire 18 connects the first arc-shaped copper clamp 16 and the first copper pressure block 12 for conductive support, realizing the convenient press-type rotation to open the circuit of the connecting strip assembly, facilitating the convenient clamping and fixing of the wire, and improving the convenience of clamping and fixing the wire of the connecting strip assembly.

[0025] Each of the protective shells 2 on one side of the movable frame 11 is equipped with a connecting frame 20. A second copper pressure block 21 is installed at the top of each connecting frame 20, and the second copper pressure block 21 extends into the interior of the connecting frame 20. A second clamping frame 22 is installed on the outer wall of each connecting frame 20. Three sets of equally spaced second threaded blocks 30 are installed inside each second clamping frame 22. A second threaded rod 23 is provided on the outer wall of each second clamping frame 22 on one side of each second threaded block 30, and the second threaded rod 23 is threadedly connected to the second threaded block 30. A second handle 24 is installed on the outer wall of each second threaded rod 23. The second threaded rod 23 is provided with a second arc-shaped copper clamp 25 at the end away from the second handle 24. The second arc-shaped copper clamp 25 is provided with a second connecting sleeve 26 on the outer wall of the second arc-shaped copper clamp 25, and the second connecting sleeve 26 is movably connected to the second threaded rod 23. The second arc-shaped copper clamp 25 is provided with a second copper braided wire 27 on the outer wall of the second arc-shaped copper clamp 25, and the second copper braided wire 27 extends into the interior of the connecting frame 20 and connects to the second copper pressure block 21. The protective shell 2 on one side of the lower pressure block 3 is provided with a first bolt 19, and the first bolt 19 extends into the interior of the protective shell 2 and connects to the lower pressure block 3.

[0026] In use, another set of wires is placed between the three sets of second arc-shaped copper clamps 25 inside the second clamping frame 22. By rotating the second handle 24, the second threaded rod 23 is rotated. Under the threaded support of the second threaded rod 23 and the second threaded block 30, the second threaded rod 23 moves inside the second threaded block 30. The second threaded rod 23 moves the second arc-shaped copper clamps 25 through the second connecting sleeve 26, so as to facilitate the movable clamping and fixing of the wires by the second arc-shaped copper clamps 25. The second copper braided wire 27 connects the second arc-shaped copper clamps 25 and the second copper pressure block 21 for conductive support. Under the support of the lower pressure block 3 and the elastic support of the spring 4, the spring 4 provides elastic force to the rack 5, so that the rack 5 provides pressure to the pressing block 6. When the pressing block 6 is not subjected to external force, the rack 5 drives the first gear 8 to rotate in the opposite direction, the first gear 8 drives the second gear 10 to rotate in the opposite direction, and the second gear 10 drives the movable frame 11 to rotate in the opposite direction, so that the movable frame 11 rotates to the top of the connecting frame 20, so that the first copper pressure block 12 and the second copper pressure block 21 come into contact, so that the two sets of wires conduct electricity. By rotating the first bolt 19, the first bolt 19 is rotated away from the inside of the protective shell 2, so that the height of the lower pressure block 3 inside the protective shell 2 can be easily adjusted, so as to adjust the elastic force of the spring and control the magnitude of the elastic force when the movable frame 11 flips. This realizes the convenient rotary connection and conduction of the connecting block assembly, facilitates the adjustment of the tightness of the contact connection during conduction, and improves the stability of the wire connection of the connecting block assembly.

[0027] Working principle: In use, the support frame 1 is first fixed inside the distribution box by the second bolt 28. The pressing block 6 drives the rack 5 to move, the rack 5 drives the first gear 8 to rotate, the first gear 8 drives the second gear 10 to rotate, the second gear 10 drives the movable frame 11 to rotate, and the movable frame 11 drives the first copper pressure block 12 to rotate, so as to facilitate the first copper pressure block 12 and the second copper pressure block 21 to change from a contact state to a separated state. This is achieved by placing a set of wires between multiple sets of first arc-shaped copper clamps 16 inside the first clamping frame 13. The first threaded rod 14 is rotated by the first handle 15, and moves inside the first threaded block 29. The first threaded rod 14 moves the first arc-shaped copper clamp 16 through the first connecting sleeve 17, so as to facilitate the movable clamping and fixing of the wire by multiple sets of first arc-shaped copper clamps 16. The first copper braided wire 18 connects the first arc-shaped copper clamp 16 and the first copper pressure block 12 for conductive support. Then, by operation, another set of wires is placed between the three sets of second arc-shaped copper clamps 25 inside the second clamping frame 22. Handle 24 drives the second threaded rod 23 to rotate, and the second threaded rod 23 moves inside the second threaded block 30. The second threaded rod 23 drives the second arc-shaped copper clamp 25 to move through the second connecting sleeve 26, so as to facilitate the movable clamping and fixing of the wire by the second arc-shaped copper clamp 25. The second copper braided wire 27 connects the second arc-shaped copper clamp 25 and the second copper pressure block 21 for conductive support. The spring 4 provides elastic force to the rack 5, so that the rack 5 provides a counter-pushing force to the pressing block 6. The rack 5 drives the first gear 8 to rotate in the opposite direction. 8 drives the second gear 10 to rotate in the opposite direction, which in turn drives the movable frame 11 to rotate in the opposite direction, so that the movable frame 11 rotates to the top of the connecting frame 20, so that the first copper pressure block 12 and the second copper pressure block 21 come into contact, so that the two sets of wires conduct electricity. By rotating the first bolt 19, the first bolt 19 is rotated away from the inside of the protective shell 2, so as to facilitate the adjustment of the height of the lower pressure block 3 inside the protective shell 2, thereby adjusting the elastic force of the spring and controlling the magnitude of the elastic force when the movable frame 11 flips, thus completing the use of the connecting row assembly.
