Detailed Description

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 2 is a schematic view of a spring capacitor clamp assembly; FIG. 3 is a schematic view of a spring capacitor clamp installed for use; aiming at the defects of the prior art, the utility model creatively provides a brand-new spring capacitor clamp design, in particular to a rectangular steel sheet 1, one side of the rectangular steel sheet 1 is provided with a spring 3 along the middle of the long edge direction, the two ends of the spring are respectively fixed on the rectangular steel sheet, the two ends of the rectangular steel sheet at the spring side are respectively provided with a fixing lug 4, the inner sides of the fixing lugs 4 are respectively provided with a spring mounting lug 2 which is respectively provided with a mounting hole 21, and hooks at the two ends of the spring are respectively hung on the two mounting holes; a simplified design can directly arrange the mounting hole on the rectangular steel sheet; when the rectangular steel sheet is straight, the spring is in a free state or a slightly stretched state; the rectangular steel sheet is bent toward the side without the spring to extend the spring. The capacitor fixing structure is realized in a matched manner, two mounting grooves 5 are formed in two sides of a capacitor B to be fixed and are arranged in parallel, the opening of each mounting groove is larger than a fixing lug, the fixing lug can be inserted into each mounting groove, and the distance between the two mounting grooves is smaller than the length of the rectangular steel sheet; when the rectangular steel sheet is straight, the spring is in a free state or a slightly stretched state.
In order to ensure that the two fixing lugs slide out of the mounting grooves without external force after being pressed into the two mounting grooves respectively, the fixing lugs are inwards turned at two ends of the fixing lugs towards the side provided with the spring respectively, and a convex part is formed at a corner.
In order to further simplify the production process, the inward-turned rear end parts of the fixing lugs are erected perpendicular to the rectangular steel sheet respectively to form two spring mounting lugs, the two spring mounting lugs are provided with a mounting hole respectively, and hooks at two ends of the spring are hung on the two mounting holes respectively.
When the capacitor needs to be installed, external force is only required to be applied to enable the rectangular steel sheet to bend towards one side without the spring, the extension spring and the two fixing lugs are pressed into the two installation grooves respectively, the spring is in a stretched state and generates return tension, and meanwhile the two fixing lugs cannot return due to the limitation of the two installation grooves, so that the rectangular steel sheet is bent to compress the capacitor to be fixed. Therefore, the whole operation is completely free from tools, and the installation can be realized only by slightly bending the rectangular steel sheet by hands. The thickness of the steel sheet and the tension of the spring can be conveniently adjusted to meet the fixing requirements of different pressures, the steel sheet and the spring with the same thickness can meet the pressure requirement in a larger range, but when vibration occurs, if a fixed capacitor vibrates, the fixed capacitor loosens, the steel sheet is inevitably driven to generate larger deformation, the spring also generates larger deformation, larger pressure is automatically generated to fasten the capacitor, and the larger the vibration is, the larger the deformation is, the larger the pressure is; and the pressure is relatively smaller under normal conditions, which is beneficial to protecting the capacitor. When the spring capacitor clamp needs to be detached, one end of the rectangular steel sheet is stressed by bare hands, the rectangular steel sheet is further bent, the convex part positioned on the fixing lug can be separated from the mounting groove, and the spring capacitor clamp can be taken down.
The two installation slots can be selected and set according to the structural position of the capacitor to be fixed, when the capacitor is arranged at the corner of the case, namely the capacitor is arranged at the corner of the bottom plate and the side plate, the capacitor can be fixed by fully utilizing the two side surfaces, and the two installation slots are respectively arranged on the bottom plate and the side plate; when the capacitor is located on the plane of the bottom plate, the two installation slots are directly arranged on two sides of the capacitor, so that different application scenes can be met, and convenience and flexibility are realized.
