When the capacitor 110 is powered on, the voltage generates an electric field (e.g., E1 and E2 in fig. 2) on the inner electrode 112, and the electric field acts on the inner electrode 112 to form a mechanical force (e.g., F11, F12, F13, F21, F22 and F23 in fig. 2), i.e., a conversion between electrical energy and mechanical energy, i.e., an inverse piezoelectric effect. The mechanical force generated by the electric field on the inner electrode 112 causes the inner electrode 112 to slightly expand and contract (see d in fig. 2), and although the expansion and contraction amount of the inner electrode 112 is small and changes on a nanometer scale, the inner electrode 112 repeatedly expands and contracts during the power-on process, so that the vibration frequency of the capacitor 110 is increased, and the capacitor 110 generates a howling sound. Note that expansion and contraction of the internal electrodes 112 are mainly caused in the stacking direction of the internal electrodes 112, that is, vibration of the capacitor 110 in the stacking direction of the internal electrodes 112 is a factor of occurrence of howling in the capacitor 110.

The second pin 130 and the first pin 120 are respectively connected to two opposite ends of the capacitor 110, and the second pin 130, the first pin 120 and the capacitor 110 form an accommodating space 150. The vibration absorber 140 is disposed in the accommodating space 150, the vibration absorber 140 includes a first supporting member 141, the first supporting member 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413, which are sequentially connected, the first free end 1411 is used for supporting the capacitor, the second free end 1413 deviates from the capacitor compared with the first free end 1411, and the first free end 1411 can move relative to the second free end 1413.

The capacitor 110 provided in the present application is a chip multilayer Ceramic capacitor (MLCC).

The first pin 120 and the second pin 130 are electrically connected to the capacitor 110, that is, the first pin 120 and the second pin 130 are made of a conductive material, such as copper, iron, or aluminum.

The vibration absorber 140 is disposed in the accommodating space 150, and the vibration absorber 140 is used for supporting the capacitor 110. The damper 140 has elasticity. In one embodiment, the vibration reducer 140 is a material having elasticity, so that the vibration reducer 140 can move along with the vibration of the capacitor 110. For example, the vibration damper 140 may be rubber, latex, elastic fiber, or the like. In another embodiment, the vibration absorber 140 is a material with a larger hardness, and the material of the vibration absorber 140 has a smaller elasticity by itself, and may even have no elasticity, and the vibration absorber 140 has elasticity due to its shape, so that the vibration absorber 140 can move along with the vibration of the capacitor 110. For example, the damper 140 may be iron, steel, rigid plastic, or the like. The vibration damper 140 may have a "C" shape, a "Z" shape, an "O" shape, or the like. In one embodiment, the vibration damper 140 is not electrically conductive, so that the vibration damper 140 can avoid the magnetic circuit or the electrical property of the capacitor 110 from being affected, and the vibration damper 140 can be beneficial to damp the capacitor 110, thereby suppressing or even eliminating the squeal.

In the present embodiment (see fig. 3), the vibration reducer 140 includes a first support 141. The first support 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 faces away from the capacitor 110 as compared to the first free end 1411. The first free end 1411 is movable relative to the second free end 1413. The first connection portion 1412 may be, but is not limited to, connect the first free end 1411 and the second free end 1413 by a bent shape, an arc shape, or the like, as long as the first free end 1411 can move relative to the second free end 1413.

The first free end 1411 can be moved either toward the second free end 1413 or away from the second free end 1413.

The capacitor assembly 100 provided by the present application includes a capacitor 110, a first pin 120, a second pin 130, and a damper 140, wherein the damper 140 is disposed in an accommodating space 150 formed by the capacitor 110, the first pin 120, and the second pin 130, and the damper 140 is used for damping the capacitor 110. Because the vibration damper supports the capacitor, the vibration amplitude and frequency of the capacitor are reduced. In addition, when the capacitor 110 works, the vibration of the capacitor 110 drives the vibration absorber 140 to move, so that the vibration absorber 140 can vibrate together with the capacitor 110, and thus a deformation quantity generated by the vibration of the capacitor 110 is transmitted to the air in the accommodating space 150, that is, the kinetic energy of the vibration absorber 140 is converted into heat energy through the friction between the vibration absorber 140 and the air and is dissipated into the air. In addition, the air in the accommodating space 150 is repeatedly compressed and released along with the vibration of the vibration absorber 140, and in the process, friction occurs between the air and the vibration absorber 140 and between the air and its molecules, so that a damping force for the vibration of the vibration absorber 140 is formed, and the amplitude and frequency of the vibration absorber 140 are suppressed. Therefore, the present application provides a capacitor assembly 100, which can reduce the vibration frequency of the capacitor 110 through the vibration damper 140 to suppress or even eliminate the squeal generated during the operation of the capacitor 110. When the capacitor assembly 100 is applied to a display device, the quality of the display device is high.

In the present embodiment, the capacitor assembly 100 includes a capacitor 110, a first pin 120, a second pin 130, and a damper 140. The second pin 130 and the first pin 120 are respectively connected to two opposite ends of the capacitor 110, and the second pin 130, the first pin 120 and the capacitor 110 form an accommodating space 150. The vibration damper 140 is disposed in the accommodating space 150, and is used for damping vibration of the capacitor 110.

The third free end 1421 is spaced apart from the first free end 1411, and is used for supporting the capacitor 110. The second connection part 1422 is connected to the first connection part 1412. The fourth free end 1423 is opposite to the capacitor 110 compared to the third free end 1421. The third free end 1421 is movable relative to the fourth free end 1423.

In this embodiment, the first connection portion 1412 may be connected to the first free end 1411 and the second free end 1413 by a bending shape, an arc shape, or the like, as long as the first free end 1411 can move relative to the second free end 1413. In the capacitor module 100 of the present embodiment, the first free end 1411 supports the capacitor 110, and the first free end 1411 is movable relative to the second free end 1413, so that the first free end 1411 is not separated from the first connection portion 1412, but is elastically deformed by the elasticity of the first support 141. The first free end 1411 can be moved either toward the second free end 1413 or away from the second free end 1413. The second connecting portion 1422 may be, but not limited to, connected to the third free end 1421 and the fourth free end 1423 through a bending shape, an arc shape, or the like, as long as the third free end 1421 can move relative to the fourth free end 1423.

The third free end 1421 can move to approach the fourth free end 1423, or move to move away from the fourth free end 1423.

In this embodiment, the third free end 1421 is used for supporting the capacitor 110, and the third free end 1421 and the capacitor 110 move together, that is, the third free end 1421 and the capacitor 110 can move together relative to the fourth free end 1423. Since the third free end 1421 and the first free end 1411 are disposed at an interval, and both the third free end 1421 and the first free end 1411 are used for supporting the capacitor 110, the third free end 1421 and the first free end 1411 support the capacitor 110 together.

For example, L₁1mm, or L₁1.1mm, or L₁1.2mm, or L₁1.3mm, or L₁1.4mm, or L₁1.5 mm.

The distance between the first free end 1411 and the second free end 1413 is L when the first support 141 is in the maximum stretching state (state c)₁₃.

If the first free end 1411 moves with a stroke L relative to the second free end 1413₁>1.5mm, the vibration amplitude of the capacitor 110 is too large, which may cause the first free end 1411 to be connected to the second free end 1413The shock or even the collision may affect the vibration damping effect of the first support 141. If the first free end 1411 moves with a stroke L relative to the second free end 1413₁<1mm, which may cause the first support member 141 not to provide a sufficiently strong damping force during the vibration of the capacitor 110, may affect the vibration damping effect of the first support member 141.

If the first free end 1411 moves with a stroke L relative to the second free end 1413₁>1.5mm, the vibration amplitude of the capacitor 110 is too large, which may cause the first free end 1411 to contact or even collide with the second free end 1413, thereby affecting the vibration damping effect of the first support 141. If the first free end 1411 moves with a stroke L relative to the second free end 1413₁<1mm, which may cause the first support member 141 not to provide a strong enough damping force during the vibration of the capacitor 110, and may affect the vibration damping effect of the first support member 141.

For example, L₂1mm, or L₂1.1mm, or L₂1.2mm, or L₂1.3mm, or L₂1.4mm, or L₂1.5 mm. Following a stroke L of movement of said third free end 1421 with respect to said fourth free end 1423₂An introduction is made. When the second supporting member 142 is in the natural state (state a), a distance between the third free end 1421 and the fourth free end 1423 is L₂₁. The third support 142 is in the maximum compression state (state B)The distance between the free end 1421 and the fourth free end 1423 is L₂₂.

It should be noted that the maximum stroke of the third free end 1421 moving toward the direction close to the fourth free end 1423 may be equal to or different from the maximum stroke of the third free end 1421 moving away from the fourth free end 1423. If the third free end 1421 moves along a stroke L relative to the fourth free end 1423₂>1.5mm, the vibration amplitude of the capacitor 110 is too large, which may cause the third free end 1421 to contact or even collide with the fourth free end 1423, which may affect the vibration damping effect of the second support 142.

Referring to fig. 4 and 7, fig. 7 is a schematic diagram illustrating a distribution of the vibration absorbers in the capacitor module according to the embodiment of fig. 4. In the present embodiment, the damper 140 includes a first support 141, or the damper 140 includes a first support 141 and a second support 142. The first support 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 faces away from the capacitor 110 as compared to the first free end 1411. The first free end 1411 is movable relative to the second free end 1413. When the vibration damper 140 includes the second supporting member 142, the second supporting member 142 has a third free end 1421, a second connecting portion 1422 and a fourth free end 1423 connected in sequence. The third free end 1421 is spaced apart from the first free end 1411, and is used for supporting the capacitor 110. The second connection part 1422 is connected to the first connection part 1412. The fourth free end 1423 is opposite to the capacitor 110 compared to the third free end 1421. The third free end 1421 is movable relative to the fourth free end 1423. In the present embodiment, the number of the dampers 140 is two or more, and the dampers 140 are provided at regular intervals in the extending direction of the first leg 120. It should be noted that the schematic diagram of the present embodiment is combined with the embodiment in fig. 4 by the number of the vibration dampers 140 being two or more, and it should be understood that the structural schematic diagram of the capacitor assembly 100 in fig. 7 does not limit the capacitor assembly 100 provided in the present application.

In the present embodiment, the extending direction of the first pin 120 refers to a direction in which the vibration reducer 140 is not wrapped by the capacitor 110, the first pin 120 and the second pin 130, that is, a direction indicated by an indication line D in fig. 7 or an opposite direction.

In the present embodiment, the number of the dampers 140 is two or more, and the dampers 140 are uniformly spaced in the extending direction of the first pins 120. In one embodiment, the number of the vibration dampers 140 is two, that is, the vibration dampers 140 may be spaced at any position in the extending direction of the first pins 120. In another embodiment, the number of the vibration dampers 140 is two or more, that is, the vibration dampers 140 are uniformly spaced in the extending direction of the first pins 120. Because the vibration of the capacitor 110 in the extending direction of the first pins 120 is distributed more uniformly, the vibration of the vibration absorbers 140 in the extending direction of the first pins 120 can increase the stability of the capacitor 110 in the working process, and when the capacitor 110 works, the vibration of the capacitor 110 drives the vibration absorbers 140 to move, so that the vibration absorbers 140 can vibrate together with the capacitor 110, and thus the deformation generated by the vibration of the capacitor 110 is transferred to the air in the accommodating space 150, that is, the kinetic energy generated by the vibration of the vibration absorbers 140 is converted into heat energy through the friction between the vibration absorbers 140 and the air and is dissipated into the air. Meanwhile, the air in the accommodating space 150 is repeatedly compressed and released along with the vibration of the plurality of vibration absorbers 140, and in the process, friction occurs between the air and the plurality of vibration absorbers 140 and between the air and the molecules of the air, so that a damping force for the vibration of the plurality of vibration absorbers 140 is formed, and the amplitude and the frequency of the vibration of the plurality of vibration absorbers 140 are suppressed. Because the plurality of vibration dampers 140 support the capacitor 110 together, the amplitude and frequency of the vibration of the capacitor 110 are further reduced, which is more beneficial to suppressing or even eliminating the squeal generated during the operation of the capacitor 110.

Referring to fig. 4 and 8, fig. 8 is a schematic view illustrating another distribution of the vibration dampers in the capacitor assembly according to the embodiment of fig. 4. In the present embodiment, the damper 140 includes a first support 141, or the damper 140 includes a first support 141 and a second support 142. The first support 141 has a first free end 1411, a first connecting portion 1412 and a second free end 1413 connected in sequence. The first free end 1411 is used to support the capacitor 110. The second free end 1413 faces away from the capacitor 110 as compared to the first free end 1411. The first free end 1411 is movable relative to the second free end 1413. When the vibration damper 140 includes the second supporting member 142, the second supporting member 142 has a third free end 1421, a second connecting portion 1422 and a fourth free end 1423 connected in sequence. The third free end 1421 is spaced apart from the first free end 1411, and is used for supporting the capacitor 110. The second connecting portion 1422 is connected to the first connecting portion 1412. The fourth free end 1423 is opposite to the capacitor 110 compared to the third free end 1421. The third free end 1421 is movable relative to the fourth free end 1423. In the present embodiment, the number of the dampers 140 is two or more. The capacitor assembly 100 has a first region 160, a middle region 170 and a second region 180 in sequence in a direction in which the first lead 120 points to the second lead 130. Wherein the first region 160 is disposed adjacent to the first lead 120. The second region 180 is disposed adjacent to the second lead 130. The intermediate region 170 is sandwiched between the first region 160 and the second region 180. Wherein the distribution density of the vibration damper 140 in the first region 160 is a first density. The distribution density in the second region 180 is a second density. The distribution density in the middle region 170 is a third density. Wherein the first density is greater than the third density and the second density is greater than the third density. It should be noted that the schematic diagram of the present embodiment is combined with the embodiment in fig. 4 by the number of the vibration dampers 140 being two or more, and it should be understood that the structural schematic diagram of the capacitor assembly 100 in fig. 8 does not limit the capacitor assembly 100 provided in the present application.

Since the capacitor 110 generally needs to be electrically connected to a circuit board through the first pin 120 and the second pin 130 to work, the first pin 120 and the second pin 130 on the capacitor 110 contact the circuit board, so that the vibration of the capacitor 110 is transmitted to the circuit board through the first pin 120 and the second pin 130, which causes the vibration of the circuit board and the vibration of the capacitor 110 to resonate, and the vibration amplitude near the first pin 120 and the second pin 130 is increased. That is, the vibration amplitude of the capacitor 110 in the first region 160 and the second region 180 is greater than the density of the middle region 170.

In the present embodiment, the dampers 140 are disposed at non-uniform intervals in the direction in which the first pins 120 point to the second pins 130, specifically, a first density of the dampers 140 disposed in the first region 160 is greater than a third density of the dampers 140 disposed in the middle region 170, that is, the number of the dampers 140 disposed in the first region 160 is greater than the number of the dampers 140 disposed in the middle region 170. The second density of the dampers 140 distributed in the second region 180 is greater than the third density of the dampers 140 distributed in the middle region 170, i.e., the number of the dampers 140 distributed in the second region 180 per unit area is greater than the number of the dampers 140 distributed in the middle region 170 per unit area. By distributing the vibration dampers 140 more densely in the first region 160 and the second region 180 than in the middle region 170, the vibration of the capacitor 110 in the first region 160 and the second region 180 with larger vibration amplitude can be damped, and the deformation of the capacitor 110 is more effectively reduced, so that the amplitude and frequency of the vibration of the capacitor 110 during operation are suppressed, the capacitor 110 is more stable during operation, and squeal generated during operation of the capacitor 110 is suppressed or even eliminated.

Referring to fig. 13, fig. 13 is a schematic structural diagram illustrating a fixed connection between a shock absorber and a capacitor in the capacitor assembly according to the embodiment of fig. 9. In this embodiment, the first lead 120 includes a first lead body 121 and a first bending portion 122. The first bending portion 122 is connected to the first lead body 121 and faces the second lead 130 compared to the first lead body 121. The second lead 130 includes a second lead body 131 and a second bending portion 132. The second bending portion 132 is connected to the second lead body 131 and faces the first lead 120 compared to the second lead body 131. When the vibration damper 140 includes the second support 142, the first free end 1411 and the third free end 1421 are spaced apart in a direction in which the first pins 120 point to the second pins 130. The second free end 1413 is fixedly connected to a surface of the first bending portion 122 facing the capacitor 110. The fourth free end 1423 is fixedly connected to the surface of the second bending portion 132 facing the capacitor 110. Alternatively, when the vibration damper 140 includes the second support 142, the first free end 1411 and the third free end 1421 are spaced apart from each other in the extending direction of the first pin 120. The second free end 1413 is fixedly connected to the surface of the first bending portion 122 facing the capacitor 110 and the surface of the second bending portion 132 facing the capacitor 110. The fourth free end 1423 is fixedly connected to the surface of the first bending portion 122 facing the capacitor 110 and the surface of the second bending portion 132 facing the capacitor 110.

In this embodiment, the first free end 1411 and the third free end 1421 are fixedly connected to the capacitor 110, and the first free end 1411 and the third free end 1421 support the capacitor 110 together.

The second supporting member 142 is fixed to the capacitor 110 through the third free end 1421, and the second supporting member 142 supports the capacitor 110 through the third free end 1421. Therefore, the vibration damper 140 is fixedly connected to the capacitor 110 and supports the capacitor 110. When the capacitor 110 is in operation, the vibration of the capacitor 110 drives the first free end 1411 to move relative to the second free end 1413, and the vibration of the capacitor 110 drives the third free end 1421 to move relative to the fourth free end 1423, so that the vibration absorber 140 can vibrate together with the capacitor 110, thereby transmitting the deformation quantity generated by the vibration of the capacitor 110 to the vibration absorber 140, and converting the kinetic energy of the vibration absorber 140 into heat energy to be dissipated into the air through the friction between the vibration absorber 140 and the air. Meanwhile, the air in the accommodating space 150 is repeatedly compressed and released along with the vibration of the first support member 141 and the second support member 142, and friction occurs between the air and the vibration absorber 140 and between molecules of the air itself in the process, so that a damping force for the vibration of the vibration absorber 140 is formed, and the amplitude and the frequency of the vibration absorber 140 are suppressed. Since the first free end 1411 and the third free end 1421 of the vibration absorber 140 are fixedly connected to the capacitor 110 and support the capacitor 110, the vibration frequency of the capacitor 110 is reduced, and the howling generated during the operation of the capacitor 110 is suppressed or even eliminated.

Referring to fig. 14, fig. 14 is a schematic structural view of the elastic abutting pins of the shock absorber and the capacitor in the capacitor assembly provided in the embodiment of fig. 13.

The fourth free end 1423 is fixedly connected to the surface of the second bending portion 132 facing the capacitor 110. Alternatively, when the vibration damper 140 includes the second support 142, the first free end 1411 and the third free end 1421 are spaced apart from each other in the extending direction of the first pin 120. The second free end 1413 is fixedly connected to the surface of the first bending portion 122 facing the capacitor 110 and the surface of the second bending portion 132 facing the capacitor 110.

In addition, in the present embodiment, the first supporting member 141 elastically abuts against the capacitor 110 and the first bending portion 122. The second supporting member 142 elastically abuts against the capacitor 110 and the second bending portion 132. It should be noted that the schematic diagram of the present embodiment is illustrated in an embodiment that the vibration reducer 140 is elastically abutted to the capacitor 110 and the first pin 120 and the second pin 130 are combined to the embodiment in fig. 11, and it is understood that the structural schematic diagram of the capacitor assembly 100 in fig. 12 does not limit the capacitor assembly 100 provided in the present application.

In the present embodiment, the damper 140 elastically abuts the capacitor 110 and the first bent portion 122 through the first supporting member 141, and elastically abuts the capacitor 110 and the second bent portion 132 through the second supporting member 142. Specifically, when the capacitor 110 is not in operation, the first free end 1411 has potential energy moving in a direction away from the second free end 1413, and the third free end 1421 has potential energy moving in a direction away from the fourth free end 1423. Therefore, the vibration damper 140 has elastic potential energy for supporting the capacitor 110 in a direction away from the vibration damper 140. When the capacitor 110 works, the capacitor is usually connected to a circuit board to work, so that the vibration of the capacitor 110 is transmitted to the circuit board, and because the vibration absorber 140 has elastic potential energy opposite to the vibration propagation, the vibration absorber 140 can form resistance to the vibration of the capacitor 110 through the elasticity recovered by deformation, and can further suppress the amplitude and frequency of the vibration of the capacitor 110, thereby suppressing or even eliminating the squeal generated by the capacitor 110 in the working process.

In the present embodiment, the circuit board assembly 10 may be used for power filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, dc isolation, and the like.

When the capacitor 110 is in operation, howling may occur due to too high self-vibration frequency. Meanwhile, when the capacitor 110 is powered on the circuit board 200 for operation, the capacitor 110 drives the circuit board 200 to vibrate, so that the capacitor 110 and the circuit board 200 generate squeal due to vibration.

In this embodiment, the capacitor module 100 is electrically connected to the circuit board 200 through the conductive members 300, so that the capacitor module 100 is electrically connected to the circuit board 200. The conductive member 300 may be, but not limited to, soldered or bonded by conductive adhesive.

In another embodiment, the first lead body 121 and the second lead body 131 are electrically connected to the circuit board 200 through the conductive member 300 to form a side connection of the capacitor assembly 100, and the first bending portion 122 and the second bending portion 132 are electrically connected to the circuit board 200 through the conductive member 300 to form a bottom connection of the capacitor assembly 100, so that the capacitor assembly 100 can be more firmly and stably connected to the circuit board 200.

In the present embodiment, the vibration damper 140 not only can reduce the vibration amplitude and frequency of the capacitor 110, but also can play a role of buffering between the capacitor 110 and the circuit board 200 to suppress or even eliminate the resonance between the capacitor 110 and the circuit board 200, so as to suppress or even eliminate the howling generated when the capacitor 110 operates on the circuit board 200.
