[0004] To address the shortcomings of the existing technology, this invention proposes a multifunctional converter.

[0005] A multi-functional converter, comprising:

[0006] A first housing, wherein a cavity is formed in the middle of the first housing, and the cavity is provided with multiple insertion holes;

[0007] A second housing connected to the first housing, the lower end of the second housing having a fixing body, and the fixing body having multiple electrical connection components in the middle.

[0009] A conductive hole is formed in the middle of the electrical connection terminal. The pressure-applying member, the limiting member, and the fixing member are disposed within the conductive hole. The electrical connection terminal is also provided with a through hole that mates with the fixing member.

[0010] When the fixing component is rotated, it pushes the pressure component, which in turn pushes multiple limiting components, causing a portion of the limiting component to extend from the through hole to the electrical connection terminal and be placed inside the fixing hole.

[0011] In this invention, the electrical connection terminal is composed of a first conductive rod and a second conductive rod, wherein the diameter of the first conductive rod is larger than the diameter of the second conductive rod, and the inner diameter of the conductive hole matches the diameter of the second conductive rod.

A gap is formed between the fixing components, and a counterweight ball is provided in the middle of the fixing component.

[0019] In this invention, a limiting hole is formed in the middle of the fixing hole, the inner diameter of the limiting hole is larger than the inner diameter of the fixing hole, and the fixing member is disposed in the limiting hole.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] like Figures 1 to 14 As shown, this multifunctional converter of the present invention includes a first housing 1, a second housing 2 and an electrical connection component 3. The electrical connection component 3 is disposed inside the second housing 2 and then covered by the first housing 1. The fixing body 4 at the lower end of the second housing 2 is an integral structure with the second housing 2.

[0038] like Figure 14 The diagram shows the existing converter 5 structure of the applicant, which has a first housing 6, a second housing 7 and a conductive component 8. It requires a support member 9 and multiple reinforcing ribs 10 and partition ribs 11 inside the second housing 7, resulting in a complex internal structure, inconvenient injection molding, and complicated assembly, which increases manufacturing costs.

[0039] A cavity 12 is formed in the middle of the first housing 1, and multiple insertion holes 13 are provided inside the cavity 12. The cavity 12 is used for docking and positioning with other converters 5. At the same time, a positioning block 14 is provided on the inner wall of the cavity 12, which can restrict the insertion direction of the electrical connection terminal 15. The insertion hole 13 is circular, which can facilitate docking of circular electrical connection terminals 15, or docking of electrical connection terminals 15 with a rectangular cross-section. The length of the rectangular electrical connection terminal 15 is less than the inner diameter of the insertion hole 13, so that it can be inserted between the second arc-shaped segments 17 on the two elastic arms 16 to achieve electrical connection.

[0040] The second housing 2 is connected to the first housing 1. The lower end of the second housing 2 is provided with a fixing body 4, and the middle of the fixing body 4 is provided with multiple electrical connection components 3. The electrical connection components 3 can be used for live wires, neutral wires, and ground wires.

[0041] The electrical connection assembly 3 includes an electrical connection terminal 15, a conductive element 18, a fixing element 19, a pressure-applying element 20, and multiple limiting elements 21. The fixing body 4 has multiple fixing holes 22 in the middle, and the electrical connection terminal 15 is disposed in the fixing holes 22. The pressure-applying element 20, the limiting element 21, and the fixing element 19 are disposed in the middle of the electrical connection terminal 15. The conductive element 18 is sleeved on the outside of the electrical connection terminal 15 and is positioned on the fixing body 4 by the electrical connection terminal 15.

[0042] A conductive hole 23 is formed in the middle of the electrical connection terminal 15. The pressure member 20, the limiting member 21 and the fixing member 19 are disposed in the conductive hole 23. The electrical connection terminal 15 is also provided with a through hole 24 that cooperates with the fixing member 19.

[0043] A conical surface 25 is formed in the conductive hole 23. The conical surface 25 is low in the middle and high at the edge, and the height of the edge is consistent with the lowest point of the through hole 24. When the pressure applying member 20 does not apply pressure to the limiting member 21, the pressure applying member 20 can be pushed upward by the counterweight ball (not shown in the figure), so that the limiting member 21 rolls towards the middle of the conical surface 25 under the action of gravity, making it convenient for the limiting member 21 to extend out of the through hole 24. The maximum diameter of the through hole 24 is smaller than the maximum diameter of the limiting member 21, so that even if the limiting member 21 is subjected to force, it cannot be completely moved out of the through hole 24, but only partially moved out. This makes the diameter of the moved part larger than the diameter of the second conductive rod 26, but smaller than that inside the fixing hole 22, thereby restricting the position of the electrical connection terminal 15, so that it cannot be detached from the fixing hole 22 under the action of the limiting member 21, and the electrical connection terminal 15 is installed on the fixing body 4.

[0044] When the fixing member 19 is rotated, it pushes the pressure member 20, which in turn pushes multiple limiting members 21, keeping the limiting members 21 moving from the middle position of the conical surface 25 to the edge position, thereby entering the through hole 24. Furthermore, to ensure the limiting members 21 accurately reach the through hole 24, multiple guide grooves (not shown in the figure) corresponding to the through hole 24 can be provided on the conical surface 25, so that the limiting members 21 are positioned within the guide grooves. The guide grooves guide the limiting members 21 into the through hole 24, and the guide grooves are set with a lower center and a higher outer edge. Finally, a portion of the limiting member 21 extends out of the through hole 24 from the electrical connection terminal 15 and is placed within the fixing hole 22.

[0045] The electrical connection terminal 15 consists of a first conductive rod 27 and a second conductive rod 26. The diameter of the first conductive rod 27 is larger than the diameter of the second conductive rod 26, and the first conductive rod 27 is located at the upper end of the second conductive rod 26. The inner diameter of the conductive hole 23 matches the diameter of the second conductive rod 26.

[0046] The first conductive rod 27 has symmetrically arranged through holes 28, and the elastic arm 16 is disposed in the through holes 28. The through holes 28 are connected to the conductive holes 23, and the conductive element 18 is disposed in the conductive holes 23 through the through holes 28.

[0047] The conductive element 18 consists of an annular body 29 and symmetrically arranged elastic arms 16. The elastic arms 16 are disposed within the through hole 28. A positioning hole 30 is formed in the middle of the annular body 29, and the second conductive rod 26 is disposed within the positioning hole 30. The annular body 29 has symmetrically arranged mounting holes 31, and the lower end of the first conductive rod 27 has a mounting post 32 that mates with the mounting hole 31. The conductive element 18 can restrict the force on the electrical connection terminal 15 inserted into the conductive hole 23, preventing it from easily detaching from the conductive hole 23, and achieving electrical connection.

[0048] The elastic arm 16 consists of an elastic segment 33 and a guide segment 34. The elastic segment 33 is connected to the annular body 29 via a first arc-shaped segment 35, and the guide segment 34 is connected to the elastic segment 33 via a second arc-shaped segment 17. A holding region 36 is formed between the second arc-shaped segment 17 and the second arc-shaped segment 17. The holding region 36 can increase in width when pushed by the electrical connection terminal 15.

[0049] The fastener 19 consists of a fastening part 37 and a threaded part 38. A hexagonal hole 39 is formed in the middle of the fastening part 37, and an internal thread 40 that mates with the threaded part 38 is provided in the conductive hole 23.

[0050] The pressure-applying component 20 is located in the middle of the multiple fixing components 19 and at the upper end. The diameter of the pressure-applying component 20 is larger than the diameter of the fixing components 19, and a gap 41 is formed between the fixing components 19. A counterweight ball is provided in the middle of the fixing component 19. The weight of the pressure-applying component 20 is less than the weight of the limiting component 21, so that when the limiting component 21 rolls towards the middle with the cooperation of the conical surface 25, it can push the pressure-applying component 20 upward. The middle of the multiple limiting components 21 forms a receiving area 43 to accommodate the pressure-applying component 20.

[0051] A limiting hole 42 is formed in the middle of the fixing hole 22. The inner diameter of the limiting hole 42 is larger than the inner diameter of the fixing hole 22. The fixing member 19 is set in the limiting hole 42.

[0052] like Figure 3 As shown, you can set the ground wire, live wire, and neutral wire, with the ground wire set between the live wire and the neutral wire.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
