[0043] In the prior art, to address the above situation, filters generally use a combination of magnetic rings and finished Y capacitors, and increase the number of filter stages to improve the filter insertion loss. However, if the magnetic ring is directly placed on the other end of the busbar assembly where the finished Y capacitor is placed, the placement of the finished Y capacitor will cause a large spacing between the ends of the busbar assembly used to place the magnetic rings, thereby increasing the link length of the manufactured magnetic rings and causing their volume and cost to exceed 40% of the previous level.

[0044] The present invention provides a filter module 100 .

[0045] See also Figures 1 to 7 In one embodiment of the present invention, the filter module 100 includes a capacitor assembly 20, a busbar assembly and a magnetic ring 40. The capacitor assembly 20 includes at least two capacitors 21, each capacitor 21 having a through hole; the busbar assembly includes at least two distribution copper bars 10 arranged side by side, each distribution copper bar 10 has a first edge 11 and a second edge 12 on the side facing away from the adjacent distribution copper bar 10, and the distance between the two first edges 11 of adjacent distribution copper bars 10 is greater than the distance between the two second edges 12 of adjacent distribution copper bars 10. The capacitor 21 is sleeved outside the distribution copper bar 10 through the through hole and is located at the first edge 11. The capacitor 21 is connected to the distribution copper bar 10; the magnetic ring 40 is sleeved outside the busbar assembly and is located at the second edge 12 of the adjacent distribution copper bar 10.

[0046] The filter module 100 in the technical solution of the present invention includes a capacitor assembly 20, a busbar assembly and a magnetic ring 40, wherein the capacitor assembly 20 includes at least two capacitors 21, and the busbar assembly includes at least two distribution copper bars 10 arranged side by side, the two distribution copper bars 10 are used as positive and negative conductive parts respectively, and the magnetic ring 40 is used to suppress electromagnetic interference, improve circuit stability, protect electronic equipment and reduce electromagnetic radiation. In this embodiment, the two capacitors 21 in the capacitor assembly 20 are respectively provided with through holes, and the two capacitors 21 are respectively arranged outside the two distribution copper bars 10 arranged in a one-to-one correspondence through the through holes. In this embodiment, the magnetic ring 40 is a common mode magnetic Ring 40, the magnetic ring 40 is simultaneously sleeved outside the two distribution copper bars 10 and is located at one end of the two capacitors 21; in order to reduce the volume of the magnetic ring 40, in this embodiment, one of the two distribution copper bars 10 is provided with a first edge 11 and a second edge 12 on a side away from the other distribution copper bar 10, wherein, since the two adjacent distribution copper bars 10 are arranged side by side, the distance between the first edges 11 of the two adjacent distribution copper bars 10 is greater than the distance between the second edges 12 of the two adjacent distribution copper bars 10, and the spacing between the sides of the two adjacent distribution copper bars 10 with the first edge 11 is greater than or equal to the spacing between the sides of the two adjacent distribution copper bars 10 with the second edge 12 In this embodiment, the two capacitors 21 in the capacitor assembly 20 are respectively and one-to-one sleeved on the first edge 11 of the distribution copper bus 10. Since the spacing between the sides of the two adjacent distribution copper buses 10 with the first edge 11 is greater than or equal to the spacing between the sides of the two adjacent distribution copper buses 10 with the second edge 12, the capacitors 21 have a wider installation spacing, making the capacitors 21 more convenient to install. As for the magnetic ring 40, the magnetic ring 40 is sleeved on the second edge 12 of the two adjacent distribution copper buses 10. Since the distance between the first edges 11 of the two adjacent distribution copper buses 10 is greater than the distance between the two adjacent distribution copper buses 10, so the magnetic ring 40 at this time requires a shorter link length during the manufacturing process than the conventional magnetic ring 40, and the manufacturing cost and the volume when the manufacturing is completed are also reduced. Through such a setting, when the capacitor assembly 20 and the magnetic ring 40 are set at both ends of the same busbar assembly, the distribution copper bus 10 in the busbar assembly is referred to the above setting, which not only ensures that the capacitor 21 is easy to install, but also effectively reduces the link length required for the magnetic ring 40 during manufacturing. The magnetic ring 40 set in this way not only reduces the cost, but also reduces its own volume. The design of the magnetic ring 40 can indirectly reduce the volume of the filter module 100.

The projections of the first connecting section 13 and the second connecting section 14 in the width direction of the distribution copper bus 10 at least partially overlap, and the second connecting sections 14 of adjacent distribution copper buses 10 are close to each other. In this embodiment, the distribution copper bus 10 includes a first connecting section 13 and a second connecting section 14 connected to each other, wherein the first edge 11 is located at one end of the first connecting section 13 away from the other distribution copper bus 10, and the second edge 12 is located at one end of the second connecting section 14 away from the other distribution copper bus 10. The projections of the first connecting section 13 and the second connecting section 14 in the width direction of the distribution copper bus 10 at least partially overlap. The width direction of the distribution copper bus 10 refers to the direction from the first edge 11 of the distribution copper bus 10 to the opposite side of the distribution copper bus 10. The second connecting sections 14 in the two adjacent distribution copper buses 10 are close to each other, thereby satisfying the above-mentioned two adjacent distribution copper buses 1 0 is greater than the distance between the second edges 12 of the two adjacent distribution copper bars 10, so that in this embodiment, the magnetic ring 40 can be miniaturized and installed on the distribution copper bar 10 for use; in other embodiments, the distribution copper bar 10 may further include a transition section, which is arranged in an arc shape, and the transition section is used to connect the first connecting section 13 and the second connecting section 14. Of course, the first connecting section 13 and the second connecting section 14 or the first connecting section 13, the transition section and the second connecting section 14 can be integrally formed, or can be later connected by welding, screwing, or clamping, etc., and no excessive restrictions are made on this.

[0048] Regarding the circuit conduction in the capacitor assembly 20, in this embodiment, one end of the capacitor 21 in the capacitor assembly 20 can be electrically connected to an external power supply or to the distribution copper bus 10 or to an external power supply through a connector, and the other end can be connected to the ground through a wire or a connector. No further restrictions are placed on this.

[0049] In one embodiment, the capacitor 21 is composed of a cylindrical insulating sleeve and a metal film wound on the sleeve. The metal film is wound onto the sleeve at high temperature, and the distribution copper bus 10 is passed through the insulating sleeve. This can increase the voltage resistance of the capacitor 21 and prevent the capacitor 21 from being broken down. The end faces on both sides of the through hole formed in the capacitor 21 are respectively provided with metal contact layers for electrical connection.

[0050] Optionally, the power distribution copper busbar 10 may be a copper busbar or an aluminum busbar, and in this embodiment, a copper busbar is preferred.

[0051] In one embodiment, if Figure 1 or Figure 2As shown, the capacitor assembly 20 also includes a grounding conductive member 23 and a power-taking conductive member 22. The grounding conductive member 23 and the power-taking conductive member 22 are arranged at both ends of the capacitor 21 along the axial direction of the through hole and are respectively connected to the capacitor 21; each capacitor 21 is connected to each distribution copper bus 10 through each power-taking conductive member 22; the capacitor 21 is located between the power-taking conductive member 22 and the magnetic ring 40. In this embodiment, the capacitor assembly 20 also includes a grounding conductive member 23 and a power-taking conductive member 22, wherein the grounding conductive member 23 and the power-taking conductive member 22 are arranged at both ends of the capacitor 21 along the circumference of the through hole of the capacitor 21, and are respectively connected to the two ends of the capacitor 21. The power-taking conductive member 22 is used to electrically connect to the external power supply, and is also respectively connected to the capacitor 21 and the distribution copper bus 10, so that each capacitor 21 is also connected to each distribution copper bus 10 through each power-taking conductive member 22. In order to make the design more reasonable, in this embodiment, the capacitor 21 is located between the power-taking conductive member 22 and the magnetic ring 40. Such an arrangement enables the capacitor 21 to better filter the distribution copper bus 10; and the grounding conductive member 23 is arranged between the capacitor 21 and the magnetic ring 40. Of course, the grounding conductive part 23 is insulated from the magnetic ring 40. In this embodiment, the grounding conductive part 23 can be a conductive metal sheet or a conductive wire. Its main function is to connect the capacitor 21 to the power supply and then to the ground to form an electrical path. There are no excessive restrictions on the specific settings of the power-taking conductive part 22 and the grounding conductive part 23. In this embodiment, metal contact layers are provided on both side end faces of the capacitor 21, and the capacitor 21 is respectively connected to the power-taking conductive part 22 and the grounding conductive part 23 through the metal contact layers on both sides. By making the capacitor 21 into a through-hole form and contacting the power-taking conductive part 22 and the grounding conductive part 23 at both ends through metal contact layers for power and grounding, a pin-free design is realized, which can solve the problem of poor high-frequency filtering performance of the finished Y capacitor 21.

In this embodiment, the power-taking conductive member 22 includes a first connecting portion 221 and a second connecting portion 222, wherein the first connecting portion 221 and the second connecting portion 222 are connected at an angle, the first connecting portion 221 is used to connect to the distribution copper bus 10 and the capacitor 21, and the second connecting portion 222 is used to electrically connect to an external power supply. In order to facilitate the electrical connection of the first connecting portion 221 with the distribution copper bus 10 and the capacitor 21, in this embodiment, first welding portions 2211 are respectively extended from both ends of the first connecting portion 221. The first welding portion 2211 is T-shaped, wherein the width of the first connecting portion 221 is not greater than the diameter of the through hole of the capacitor 21, so that the first welding portion 2211 is just located at the end face of the capacitor 21 where the through hole is formed, thereby making it easy for the first welding portion 2211 to be welded to one end face of the capacitor 21. Through such a configuration, the capacitor 21 does not need to be electrically connected to the external power supply through a wire, thereby reducing the formation of parasitic inductance.

[0053] In one embodiment, if Figure 5As shown, the grounding conductive member 23 includes a first conductive portion 231 and a second conductive portion 232, and the first conductive portion 231 and the second conductive portion 232 are connected at an angle, the first conductive portion 231 is used to be electrically connected to the capacitor 21, and the second conductive portion 232 is used for grounding; and / or the first conductive portion 231 is provided with a through hole 2311 for the distribution copper bus 10 to pass through, and a plurality of second welding portions 2312 are provided at intervals around the outer periphery of the through hole 2311, and the second welding portions 2312 are used for welding the grounding conductive member 23 to the capacitor 21.

The first conductive portion 231 is connected to the capacitor 21, and the second conductive portion 232 is used for grounding. In this embodiment, the first conductive portion 231 is provided in a sheet shape, and a through hole 2311 for the distribution copper bus 10 to pass through is provided on the first conductive portion 231. In this embodiment, the aperture of the through hole 2311 is larger than the width of the distribution copper bus 10, so that the distribution copper bus 10 is centered when passing through the grounding conductive member 23. In the empty state, that is, the distribution copper bus 10 is not electrically connected to the grounding conductive member 23, in order to facilitate welding of the first conductive portion 231 and the other end face of the capacitor 21, in this embodiment, a plurality of second welding portions 2312 are provided in an outer peripheral ring around the through hole 2311. The number of the second welding portions 2312 is three, and the three second welding portions 2312 are arranged at an interval of one hundred and twenty degrees from each other around the center of the hole 2311. Such an arrangement can not only ensure the structural strength of the grounding conductive member 23 itself, but also effectively ensure the stable connection between the grounding conductive member 23 and the capacitor 21.

[0054] In one embodiment, if Figure 2 and Figure 6As shown, the capacitor assembly 20 further includes an insulating sleeve 24, which is used for the distribution copper bus 10 to pass through and the capacitor 21 to be installed, so that the distribution copper bus 10 and the through-hole of the capacitor 21 are insulated, and the insulating sleeve 24 is connected to the grounding conductive member 23. In order to prevent the distribution copper bus 10 from being electrically connected to the grounding conductive member 23 and at the same time to position the capacitor 21, in this embodiment, the capacitor assembly 20 further includes an insulating sleeve 24, wherein the insulating sleeve 24 includes a fitting portion 242 and a protruding portion 241, wherein the protruding portion 241 is located on one side of the fitting portion 242. In this embodiment, the insulating sleeve 24 is arranged on the first conductive portion 231 of the grounding conductive member 23 of the above embodiment. Specifically, the protruding portion 241 passes through the first conductive portion 23 1, the fitting portion 242 is located on one side of the through-hole 2311 and fits with the first conductive portion 231. Both the protruding portion 241 and the fitting portion 242 are provided with holes for the distribution copper bus 10 to pass through, and the capacitor 21 is sleeved on the outer periphery of the protruding portion 241 through the through-hole. Such a configuration can not only improve the insulation performance of the electrical connection between the through-hole of the capacitor 21 and the distribution copper bus 10, but also enhance the connection stability among the distribution copper bus 10, the grounding conductive member 23 and the capacitor 21.

[0055] In one embodiment, if Figure 2 As shown, the busbar assembly further includes a rubber sleeve 15, which is sleeved over the outer periphery of the distribution copper bar 10 and located at the second edge 12, so as to insulate the magnetic ring 40 from the distribution copper bar 10.

The protective cover 32 is detachably provided on the protective sleeve 31 to cover the cavity 311; and / or the magnetic ring 40 is made of amorphous nanocrystals. In order to protect the magnetic ring 40 and the distribution copper bus 10, in this embodiment, the filter module 100 also includes a protection component 30, which includes a protective sleeve 31 and a protective cover 32. The protective sleeve 31 has a hole for the busbar component to pass through and a cavity 311 for accommodating the magnetic ring 40.

The setting of the positioning portion can also improve the insulation performance between the magnetic ring 40 and the busbar assembly. After the magnetic ring 40 is positioned in the cavity 311 of the protective cover 31, the protective cover 32 can cover the cavity opening of the cavity 311 to achieve the effect of covering the cavity 311, making it difficult for external dust to enter and affect the magnetic ring 40; in other embodiments, the magnetic ring 40 is made of amorphous nanocrystals, and the magnetic ring 40 set in this way has high efficiency energy storage, low loss, high magnetic permeability, low hysteresis, anti-electromagnetic interference and stability.
