[0016] Controller box 200 and assembly hole 201 . DETAILED DESCRIPTION
[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0018] The following is combined with Figure 1-Figure 5 The capacitor structure according to the embodiment of the utility model and the structure of assembling the capacitor to the controller box are described in detail.
[0019] like Figure 1-Figure 3 As shown, the capacitor according to the embodiment of the present invention includes a housing 100 .
[0020] Specifically, the housing 100 is used to accommodate the capacitor element assembly. A hot melt component 110 is provided on the outer surface of the housing 100. The hot melt component 110 is suitable for being fixedly connected to the controller box 200 by hot melting.
[0021] That is to say, compared with the existing capacitor that uses screw locking to fix the connection to the controller box 200, the present application sets a hot melt component 100 on the shell 100, and the hot melt component 100 can be fixedly connected to the controller box 200 by hot melting.
[0022] Therefore, according to a capacitor structure of an embodiment of the utility model, a hot melt component 110 is arranged on the shell 100, and the hot melt component 110 can be fixedly connected to the controller box 200 by hot melting, so that the capacitor is fixed on the controller box 200 by hot melting. In this way, the use of components such as screws and metal nests can be eliminated, thereby reducing the assembly cost of the capacitor.
[0023] The above implementation is the most basic solution of this application, which can solve the problems raised in the background technology and achieve the purpose of this application. The following improves the above basic solution in many aspects to further improve its performance, thereby achieving better implementation effect.
[0024] The capacitor element assembly can adopt an existing structure, such as two busbars connected to a plurality of capacitor cores, and separated and insulated by insulating paper in the overlapping area, so as to assemble the two busbars, a plurality of capacitor cores and insulating paper into one, and complete the capacitor element assembly. The capacitor element assembly is then accommodated in the accommodating cavity of the housing 100, and then a filling resin in a liquid phase state is injected into the accommodating cavity from the open mouth of the housing 100, so that the space between the capacitor element assembly and the housing 100 is filled with the filling resin; if the filling resin injection is completed, the filling resin in the housing 100 can be hardened, and the capacitor element assembly is fixed relative to the housing 100 by the hardened filling resin.
[0025] Example
[0026] Figure 1 FIG. 1 is a schematic diagram of the structure of the housing 100 of the film capacitor. Figure 1 As shown, the hot melt component 110 is a protrusion protruding outward from the outer surface of the housing 100. This facilitates the manufacture of the hot melt component 110, and the hot melt component 110 has opposite ends 110a and a root 110b, the root 110b is fixed on the housing 100, and the end 110a is a free end.
[0027] The protrusion may be cylindrical, and the cylindrical protrusion is convenient to extend from the shell 100 , and the cylindrical protrusion can be adapted to the assembly hole of the existing controller box 200 .
[0028] Specifically, Figure 5 As shown, the controller housing 200 is provided with a through assembly hole 201, and after the hot melt 110 is inserted into the assembly hole 201, the end of the hot melt 110 is hot-melted to form a stopper 111 that abuts against the edge of the assembly hole 201, so as to fix the connection with the controller housing 200. That is to say, in the process of assembling the capacitor to the controller housing 200, the end 110a of the hot melt 110 is inserted from one side of the assembly hole 201 and passed out from the other side, and then the end 110a is hot-melted by a hot melt machine, so that the end 110a of the hot melt 110 is melted and solidified to form a stopper 111. The stopper 111 directly abuts against the edge of the assembly hole 201, so that the hot melt 110 is fixedly connected to the controller housing 200, and the hot melt 110 is prevented from being separated from the assembly hole 201.
[0029] Combination Figure 2After being formed, the limit block 111 may be in the shape of a disk, and the diameter of the limit block 111 may be larger than the inner diameter of the assembly hole 201 , so that the hot melt component 110 may be fixedly connected to the controller housing 200 , thereby preventing the hot melt component 110 from being separated from the assembly hole 201 .
[0030] In addition, multiple hot melt components 110 can be provided, and multiple hot melt components 110 are distributed at intervals on the outer surface of the housing 100. In this way, the capacitor is firmly connected to the controller housing 200. Each hot melt component 110 is fixedly connected to the controller housing 200 by the above-mentioned hot melt method.
[0031] In this embodiment, the hot melt 110 is arranged on the outer bottom surface of the housing 100, so that the entire capacitor is assembled in the controller box 200. Of course, in other examples, the hot melt 110 can also be arranged on other outer surfaces of the housing 100, which can be specifically arranged according to the assembly surface of the capacitor.
[0032] Furthermore, a reinforcing protrusion 120 extends from the outer surface of the housing 100 at the periphery of the root 110b of the hot melt component 110. The reinforcing protrusion 120 can reinforce the hot melt component 110. The reinforcing protrusion 120 can be in the shape of a disk.
[0033] Furthermore, the hot melt component 110 , the reinforcing protrusion 120 and the housing 100 are integrally formed, for example, by integral injection molding or by two-color injection molding, so as to facilitate the production of the housing 100 .
