[0002] Existing electronic equipment has certain mandatory requirements for EMC.

At the same time, it can also prevent the electromagnetic energy generated by the components from affecting the normal operation of surrounding equipment.

[0003] However, existing shielding components are generally made of metal plates and assembled independently in electronic devices, making the assembly of electronic devices more complicated. In addition, there is often a problem of unstable support of the shielding components, which causes the shielding components to emit additional noise when the electronic equipment vibrates.

[0026] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0027] like Figures 1 to 3 As shown, the utility model discloses a capacitor, which includes a capacitor body 1 and a shielding member 2; the shielding member 2 is fixedly connected to the capacitor body 1, and the shielding member 2 is equipped with multiple supporting members 3, and each supporting member 3 is provided with a lower support leg 31 against the capacitor body 1.

[0028] In the present invention, the capacitor of the present invention is directly provided with a shielding part 2 fixedly connected to the capacitor body 1, so that the capacitor is directly integrated with the shielding part 2, which can reduce the process of installing the shielding part 2 on subsequent electronic equipment and facilitate the assembly of electronic equipment; in addition, the shielding part 2 is equipped with multiple support parts 3, and each support part 3 is provided with a lower support foot 31 that rests against the capacitor body 1 to form multi-point support for the shielding part 2, so that the shielding part 2 is firmly supported and not easy to shake, effectively avoiding the shielding part 2 from emitting additional noise when the electronic equipment is vibrating.

[0029] In an embodiment of the present utility model, the capacitor body 1 may include a shell 11, a plurality of capacitor cores 12 arranged in the shell 11, two busbars 13 connecting the capacitor cores 12 in parallel, and a potting compound 14 filled in the shell 11 and covering the capacitor cores 12 and the busbars 13; the two busbars 13 are respectively connected to the two ends of each capacitor core 12 so that the capacitor cores 12 are connected in parallel, and the potting compound 14 can protect each capacitor core 12 and each busbar 13 and prevent each capacitor core 12 and each busbar 13 from loosening.

[0030] In an embodiment of the present invention, the capacitor body 1 further includes pole pieces 15 connected to the two busbars 13 respectively. The capacitor body 1 is connected to other components of the electronic device via the two pole pieces 15 .

[0031] In an embodiment of the present invention, the outer shell 11 of the capacitor body 1 has an opening on one side, and the lower legs 31 of each support member 3 abut against the potting compound 14 of the capacitor body 1. The shielding member 2 abuts against the opening of the outer shell 11, thereby improving the support stability of the shielding member 2. The shielding member 2 and the outer shell 11 are both made of metal, thereby effectively preventing each capacitor core 12 from interfering with the outside world and preventing each capacitor core 12 from being interfered with by the outside world.

[0032] In an embodiment of the present invention, the shielding member 2 can be bonded to the capacitor body 1 via a connecting adhesive 4. This connecting adhesive 4 makes surface contact with the shielding member 2 and the capacitor body 1, thereby ensuring a secure connection between the shielding member 2 and the capacitor body 1. Specifically, the connecting adhesive 4 can bond the shielding member 2 to the potting adhesive 14 of the capacitor body 1. Furthermore, the shielding member 2 is secured to the outer shell 11 of the capacitor body 1 via at least two screws, further enhancing the stability of the shielding member 2.

[0033] In an embodiment of the present invention, each support member 3 may be provided with an upper support foot 32 that protrudes from the shielding member 2. In this way, for electronic equipment that needs to be equipped with additional shielding members, the upper support foot 32 of each support member 3 can provide stable support for the installed additional shielding members, thereby avoiding additional noise emitted by the installed additional shielding members when the electronic equipment is vibrating.

[0034] In the embodiment of the present invention, the support member 3 is made of plastic and is overmolded onto the shielding member 2. This arrangement reduces the cost of the support member 3 and simplifies assembly. It should be noted that the support member 3 can also be combined with the shielding member 2 through other connection methods, such as an integral arrangement, a snap-fit ​​connection, or screw locking.

[0035] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
