Description

Technical Field

[0001] The present invention relates to the technical field of capacitors, and in particular to a mounting card and a capacitor housing having the mounting card. Background Art

[0002] Capacitors, as important electronic components in modern electronic devices, are widely used in new energy vehicle charging stations, industrial inverters, energy storage devices, and other fields. As electronic devices move toward miniaturization, integration, and higher performance, higher requirements are placed on the installation stability, electrical performance, and heat dissipation capabilities of capacitors.

[0003] Common capacitor installation methods often use screw fastening or gluing. Screw fastening not only reduces installation efficiency, increasing labor costs and assembly time, but also can easily loosen screws in high-frequency vibration environments, resulting in unstable capacitor installation and affecting normal equipment operation. Summary of the Invention

[0004] In order to solve the technical problems existing in the background technology, the present invention provides a mounting card and a capacitor housing having the mounting card.

[0006] Preferably, the first elastic portion, the second elastic portion and the supporting portion are integrally formed, and the first elastic portion, the second elastic portion, the supporting portion and the connecting portion are located on the same plane.

[0007] Preferably, the first elastic portion is provided with a plurality of first card slots, and the second elastic portion is provided with a plurality of second card slots, and the first card slots and the second card slots have the same size.

[0008] The capacitor housing with a mounting card comprises a housing, which is a cylindrical metal shell. The connecting portion and the housing are coaxially arranged, the mounting end is connected to the bottom of the housing, and the connecting portion and the housing are integrally formed.

[0009] Preferably, it further comprises a plate body that can be used to install the shell, the plate body has a mounting hole, and the diameter of the mounting hole is greater than the length of the support portion.

[0010] Preferably, the diameter of the mounting hole is smaller than the maximum distance between the first elastic portion and the second elastic portion.

[0011] Preferably, an insulating gasket is further included, which is located between the shell and the plate body. The insulating gasket has a circular hole, and the diameter of the circular hole is larger than the diameter of the mounting hole.

[0012] Preferably, the insulating gasket is a thermally conductive silicone gasket.

[0013] The advantages of the mounting card and capacitor housing incorporating it proposed in this invention are: A vertically symmetrical structure of connecting and supporting parts, combined with elastic portions at both ends, a slot, and a coaxial metal housing, allows for secure assembly through an integrated molding process. Its elastic clamping mechanism, combined with the appropriately sized mounting holes and slots on the board, enables quick, screw-free installation, improving installation efficiency. The thermally conductive silicone insulating gasket ensures both electrical insulation and efficient heat dissipation. Integrated production reduces costs, and the universal structure adapts to multiple scenarios, resulting in significant advantages such as structural stability, easy assembly and disassembly, and reliable performance.

[0015] Figure 2 This is a bottom structural diagram of an installation card proposed by the present invention and a capacitor housing having the installation card. DETAILED DESCRIPTION

[0016] refer to Figure 1-2 The present invention proposes a mounting card and a capacitor housing having the mounting card. The mounting card is mainly composed of a connecting part 1 and a supporting part 2. The connecting part 1 is a rod-shaped structure, the lower end of which is a connecting end, and the upper end is a mounting end. The connecting end and the supporting part 2 are vertically fixedly connected, and the connection between the connecting end and the supporting part 2 is located in the middle of the supporting part 2. This symmetrical connection design can ensure that the mounting card is uniformly stressed and improve the overall stability. The first elastic part 3 and the second elastic part 4 are respectively installed at both ends of the supporting part 2. The axis of the connecting part 1 is the symmetric axis of the first elastic part 3 and the second elastic part 4, so that the force characteristics of the mounting card in all directions remain consistent;

[0017] In order to further enhance the overall strength and reliability of the mounting card, the first elastic portion 3, the second elastic portion 4 and the support portion 2 are manufactured using an integrated molding process. This process avoids weak links that may be caused by splicing components, effectively improving the integrity and durability of the structure. At the same time, the first elastic portion 3, the second elastic portion 4, the support portion 2 and the connecting portion 1 are all on the same plane, which not only makes the structure of the mounting card more compact, but also facilitates subsequent assembly with other components, simplifies the production process, and reduces assembly difficulty and errors.

[0018] A plurality of first card slots 5 are provided on the first elastic portion 3, and a plurality of second card slots 6 are correspondingly provided on the second elastic portion 4. The first card slots 5 and the second card slots 6 are exactly the same in size. The design of these card slots plays an important role. During the installation process, they can cooperate with the protrusions or buckles on the plate 8 or other fixed structures to form a firm card connection structure, further enhancing the connection stability between the installation card and the installation object, and preventing the installation card from loosening or displacement.

[0019] The capacitor housing with the mounting clip includes a housing 7. The housing 7 is a cylindrical metal shell. The metal housing 7 has good electromagnetic shielding performance, which can effectively reduce the impact of external electromagnetic interference on the internal electrical performance of the capacitor, and also provides reliable mechanical protection for the capacitor. The connecting portion 1 is coaxially arranged with the housing 7, and the mounting end is connected to the bottom of the housing 7 in an integrally formed manner. This connection method ensures a tight connection between the connecting portion 1 and the housing 7, ensures that the capacitor can be stably fixed to the external structure through the mounting clip during installation, and reduces contact resistance and signal interference that may be caused by a loose connection.

[0020] The capacitor housing also includes a plate body 8 for mounting the housing. A mounting hole 9 is provided on the plate body 8. The diameter of the mounting hole 9 is greater than the length of the support portion 2. Such a size design enables the support portion 2 to pass through the mounting hole 9 smoothly, facilitating the initial assembly of the mounting card and the plate body 8. At the same time, the diameter of the mounting hole 9 is less than the maximum distance between the first elastic portion 3 and the second elastic portion 4. When the support portion 2 passes through the mounting hole 9, the first elastic portion 3 and the second elastic portion 4 will fit tightly with the surface of the plate body 8. The clamping force generated by their elastic deformation is used to fix the capacitor housing on the plate body 8, thereby achieving fast, convenient and stable installation.

[0021] In addition, the capacitor housing structure is also equipped with an insulating gasket 10, which is located between the housing 7 and the plate 8. A circular hole 11 is opened on the insulating gasket 10, and the diameter of the circular hole 11 is larger than the diameter of the mounting hole 9, ensuring that the mounting card and the housing 7 can be smoothly installed through the circular hole 11. The insulating gasket 10 is made of thermally conductive silicone gasket. This material has dual important functions. On the one hand, it can effectively isolate the electrical connection between the housing 7 and the plate 8, prevent the occurrence of electrical faults such as short circuits, and ensure the normal operation of the capacitor in the circuit; on the other hand, the thermally conductive silicone gasket has good thermal conductivity, which can quickly conduct the heat generated by the capacitor during operation to the plate 8, and then dissipate it to the surrounding environment through the plate 8, which helps to reduce the operating temperature of the capacitor and improve the service life and working stability of the capacitor.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and the inventive concept of the present invention, should be covered by the scope of protection of the present invention.
