Description

Technical Field

[0001] The utility model relates to a protection device in an inductor for protecting an inductor coil. Background Art

[0002] At present, the inductor body used in the photovoltaic energy storage field is usually composed of side columns, middle column magnetic core, coil and circular magnetic core, which are placed in an aluminum shell, and thermal conductive silicone is poured between the inductor body and the aluminum shell. However, the existing inductor body and aluminum shell cannot accurately locate the distance between them, resulting in poor heat dissipation and insulation; it is also impossible to accurately fix the various components in the inductor body assembly, which increases the difficulty of inductor manufacturing and glue filling assembly process. Utility Model Content

[0003] In order to solve the problem of fixing and positioning an inductor body and its components, the utility model provides a coil protection shell. The technical solution of the utility model is as follows: there is a body, a circular hole is arranged at the center of the body, an annular protruding frame is arranged at the edge of the circular hole, straight ribs are arranged on the left and right ends of the body and on the other surface opposite to the annular protruding frame, and a concave groove is arranged at the upper and lower ends of the body.

[0004] The beneficial effect of the utility model is that the side columns, the middle column magnetic core, the coil and the circular magnetic core of the inductor are integrated and assembled by adopting the utility model, which simplifies the assembly and the fixation between the components and improves the assembly efficiency and the product rigidity. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] Figure 1 , 2 It is a structural schematic diagram of the utility model;

[0006] Figure 3 It is an application schematic diagram of the utility model.

[0007] In the figure, 1: body 1, 2: round hole, 3: annular protruding frame, 5: straight rib, 4: concave groove, 6: middle column, 7: coil, 8: side column, 9: circular core. DETAILED DESCRIPTION

[0008] like Figure 1 , 2 As shown, the utility model has a body 1, a circular hole 2 is arranged at the center of the body 1, an annular protruding frame 3 is arranged at the edge of the circular hole 2, a straight rib 5 is arranged on the left and right ends of the body and on the other side opposite to the annular protruding frame 3, and a concave groove 4 is respectively arranged at the upper and lower ends of the body.

[0009] like Figure 3As shown, the utility model is applied to the assembly of the inductor. First, the coil 7 is sleeved on the middle column 6, and two utility models are respectively assembled at the two ends of the middle column 6, so that the end of the middle column 6 is inserted into the circular hole 2, and then the side column 8 and the circular magnetic core 9 are respectively assembled in the concave groove 4 and the straight rib 5, so as to form an integrated assembly of the inductor.

[0010] The above-mentioned specific implementation methods are only exemplary and are intended to better enable those skilled in the art to understand this patent. They should not be understood as limiting the scope of this patent. Any changes or modifications that are essentially the same or equivalent to the technical content made according to the technical solution disclosed in this patent shall fall within the scope of this patent.
