Abstract

An assembling structure includes a ground wire, an inverter, a first fixing element, and a clamping device. The inverter includes a casing. The clamping device is disposed on the casing. The clamping device includes a first end, a second end, and a pressing part between the first end and the second end. The second end of the clamping device is previously fixed on the casing. After the ground wire is transferred through an entrance between the first end of the clamping device and the casing, the ground wire is clamped between the pressing part and the casing. Afterwards, by using the fixing element, the first end of the clamping device is fixed on the casing, the ground wire is fixed on the casing by the pressing part of the clamping device, and the inverter is fixed on the rack simultaneously.

Claims

1. An assembling structure, comprising:

a ground wire;

an inverter comprising a casing, wherein said casing has a first perforation;

a first fixing element; and

a clamping device disposed on the casing, wherein said clamping device comprises a first end, a second end, and a pressing part between said first end and said second end, wherein said second end of said clamping device is previously fixed on said casing, and said first end of said clamping device has a first opening, wherein after said ground wire is transferred through an entrance between said first end of said clamping device and said casing, said ground wire is clamped between said pressing part and said casing, wherein after said first fixing element is tightened into said first opening and said first perforation, said first end of said clamping device is fixed on said casing, said ground wire is fixed on said casing by said pressing part of said clamping device, and said inverter is fixed on a rack simultaneously.

2. The assembling structure according to claim 1, wherein said first end, said second end and said pressing part of said clamping device are integrally formed.

3. The assembling structure according to claim 1, wherein said first end and said second end are extended from two opposed sides of a bottom of said pressing part, respectively.

4. The assembling structure according to claim 1, wherein said casing further comprises a U-shaped recess, wherein said U-shaped recess is protruded from a bottom surface of said casing, and an outer wall of said U-shaped recess is partially contacted with said rack.

5. The assembling structure according to claim 4, wherein said pressing part of said clamping device is accommodated within said U-shaped recess, and said ground wire is clamped between said pressing part and an inner surface of said U-shaped recess.

6. The assembling structure according to claim 5, wherein after said pressing part of said clamping device is accommodated within said U-shaped recess, a receiving space is defined by said first end of said clamping device, said pressing part and said inner surface of said U-shaped recess, wherein said ground wire is introduced into a region between said pressing part and said inner surface of said U-shaped recess through said entrance and said receiving space.

7. The assembling structure according to claim 6, wherein a width of said receiving space is slightly larger than a diameter of said ground wire.

8. The assembling structure according to claim 5, wherein said first end and said second end are extended from two opposed sides of a top of said pressing part, respectively.

9. The assembling structure according to claim 1, wherein said pressing part of said clamping device comprises a first lateral plate and a second lateral plate, wherein said first lateral plate and said second lateral plate are extended downwardly from two opposite sides of a top of said pressing part, and said first lateral plate and said second lateral plate are parallel with each other.

10. The assembling structure according to claim 9, wherein said first lateral plate comprises at least one first notch, and said second lateral plate comprises at least one second notch, wherein a width of said first notch and a width of said second notch match a diameter of said ground wire, so that said ground wire is at least partially accommodated within said first notch and said second notch.

11. The assembling structure according to claim 1, wherein said second end of said clamping device further comprises a second opening, and said casing further comprises a second perforation corresponding to said second opening

12. The assembling structure according to claim 11, further comprising a second fixing element, wherein after said second fixing element is tightened into said second opening and said second perforation, said second end of said clamping device is previously fixed on said casing.

13. The assembling structure according to claim 1, wherein after said first fixing element is tightened into said first opening, said first perforation and a corresponding hole of said rack, said first end of said clamping device is fixed on said casing, said ground wire is fixed on said casing by said pressing part of said clamping device, and said inverter is fixed on said rack simultaneously.
