DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 4 As shown, a capacitor module that is convenient for grounding in this solution includes: a capacitor component 1, a conductive screw 3 and a conductive fastener 4.

[0023] Among them, the capacitor 1 has internal electronic components and a conductive shell 2 wrapped around the outside of the electronic components. The electronic components are used to achieve the electrical properties of the capacitor 1. The conductive shell 2 is preferably a hollow cylindrical structure. The conductive shell 2 is arranged to provide protection for the electronic components to prevent external moisture and dust from affecting the normal operation of the electronic components inside. The end of the conductive shell 2 is connected to a conductive screw 3. The conductive screw 3 and the conductive shell 2 are both made of metals with good conductivity that are widely used in industry, such as iron, copper, iron alloy or copper alloy. The axial direction of the conductive screw 3 is parallel to the height direction of the conductive shell 2.

[0024] In this solution, when the conductive shell 2 adopts a cylindrical structure, the axis of the conductive screw 3 is collinear with the axis of the conductive shell 2. Of course, in order to facilitate the installation between the capacitor 1 and the opponent 14, the shape of the conductive shell 2 can also be changed accordingly, and the installation position between the conductive screw 3 and the conductive shell 2 can also be adaptively modified; the conductive clip 4 is connected to the end of the conductive screw 3 away from the conductive shell 2 to fix the capacitor 1 on the opponent 14. The conductive screw 3 and the conductive clip 4 are arranged to provide a grounding component for the capacitor 1.

[0025] In this solution, the conductive housing 2 , the conductive snap-fit member 4 and the conductive screw 3 are provided to realize the grounding function of the capacitor 1 , thereby providing protection for the circuit connected to the capacitor 1 .

[0026] In this solution, the conductive screw 3 is connected to the conductive shell 2 by welding or riveting.

[0027] The end of the conductive screw 3 away from the conductive shell 2 has a hole structure 5, and the conductive clip 4 is provided with a through hole 6 adapted to the hole structure 5. The rivet 7 passes through the through hole 6 and the hole structure 5 in sequence to fix the conductive clip 4 on the conductive screw 3.

[0028] The hole structure 5 on the conductive screw 3 can be a through hole or a blind hole, and the structure can be cylindrical or in other shapes, as long as it can achieve the purpose of fixing with the rivet 7.

[0029] A first elastic portion 8 is provided at one end of the conductive clip 4 facing the conductive screw 3. The first elastic portion 8 can store elastic potential energy due to the conductive clip 4 being fixed on the conductive screw 3, so as to provide thrust for the conductive clip 4. The direction of the thrust is opposite to the direction of the thrust exerted by the rivet 7 on the conductive clip 4, so as to make the conductive clip 4 and the conductive screw 3 abut more tightly.

[0030] The conductive clip 4 includes a bottom 9 that abuts against the conductive screw 3, and two sides of the bottom 9 are provided with a first part 10 extending obliquely along the axial direction of the conductive screw 3, and a second part 11 extending obliquely along the horizontal direction, wherein the angle between the first part 10 and the second part 11 is less than or equal to 90°.

[0031] Specifically, a second elastic portion 12 is provided on the first portion 10, and a third elastic portion 13 is provided on the second portion 11. The second elastic portion 12 and the third elastic portion 13 can generate elastic deformation when the conductive snap member 4 is connected to the opponent member 14, and apply reverse thrust to the opponent member 14.

[0032] like Figure 1 and Figure 3 As shown, a mounting hole 15 is provided on the counterpart 14. During the process of inserting the capacitor module into the mounting hole 15, the second elastic portion 12 is first squeezed by the side wall of the mounting hole 15 and elastically deformed, thereby enabling the second elastic portion 12 to pass through the mounting hole 15. After the second elastic portion 12 passes through, the force applied to the second elastic portion 12 disappears, and the second elastic portion 12 returns to its original shape and rests against the bottom end of the counterpart 14, preventing the capacitor module from disengaging from the counterpart 14 in the opposite direction. At the same time, during the process of the second elastic portion 12 passing through, the third elastic portion 13 is squeezed by the upper end face of the counterpart 14 and also clings to the upper end face of the counterpart 14. At this time, the counterpart 14 is subjected to pressure from the second elastic portion 12 and the third elastic portion 13, and the pressures of these two parts on the counterpart 14 are in opposite directions, making the connection between the capacitor module and the counterpart 14 tighter and also preventing relative rotation between the capacitor module and the counterpart 14.

[0033] Preferably, the conductive clip 4 includes two spring pieces with a Z-shaped cross section, and the two spring pieces are symmetrically arranged along the axis of the conductive screw 3 to facilitate the molding of the conductive clip 4.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement status of the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0036] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them with similar methods, without departing from the scope defined by the spirit of the present invention.
