Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a novel multi-core capacitor. Background Art

[0002] Capacitors, usually referred to as their ability to hold charge, are represented by the letter C. As the name suggests, capacitors are containers for electricity and are devices that hold charge. Capacitors are one of the electronic components used in large quantities in electronic equipment, and are widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control.

[0003] The existing patent (application number 202321529965.0) discloses a new type of multi-core capacitor, which includes at least two first and second core groups connected in series, and a connection assembly connected to the first and second core groups. The first and second core groups are composed of multiple capacitors arranged at intervals in the direction of current, and the connection assembly includes positive and negative pole connection groups respectively arranged on both sides of the first and second core groups, and at least one transfer connection group arranged between the first and second core groups. The transfer connection group includes a first connection piece for connecting the negative poles of multiple capacitors of the first core group, a second connection piece for connecting the positive poles of multiple capacitors of the second core group, and two lap pieces respectively overlapped on both sides of the second connection piece.

[0004] Existing capacitors do not have good heat dissipation, especially when there are many inner cores, it is easier for heat to accumulate inside and the temperature to rise, thus affecting the service life of the capacitor; in addition, the capacitor is also inconvenient to install and disassemble.

The clamping plate is inserted into the slot, and after the clamping plate is inserted, the spring columns on it will also be contracted by force, thereby generating an inward clamping force, so that the fixing seat is clamped in the capacitor housing, and when the core needs to be taken out, the clamping plate is pushed out of the slot by pushing the clamping plate, and the fixing seat and the core can be pulled out of the capacitor housing by the pull plate, thereby facilitating the installation or removal of the core.

[0009] Preferably, the heat dissipation device comprises a first heat conducting plate and a second heat conducting plate, the front end of the first heat conducting plate and the rear end of the second heat conducting plate are both equipped with graphite heat sinks, and the first heat conducting plate and the second heat conducting plate are respectively installed at the front end and the rear end of the core. The graphite heat sink has a unique grain orientation, and conducts heat uniformly in two directions. The lamellar structure can adapt well to any surface, thereby enabling rapid heat conduction to the chip and increasing its service life.

[0010] Preferably, the mounting device comprises a fixing seat, two fixing seats are provided, a pull plate is installed on the upper end of the two fixing seats, a slot is opened on the lower part of the opposite ends of the two fixing seats, and the two fixing seats are respectively installed at the left and right ends of the core.

[0014] 1. The two fixing seats on the installation device are respectively installed on the left and right ends of the core. At this time, the two fixing seats are pushed into the capacitor housing. When the fixing seats are pushed to the bottom of the capacitor housing, the card plate on the clamping device is then clamped into the card slot. After the card plate is clamped, the spring column on it will also be forced to shrink, thereby generating an inward clamping force, thereby clamping the fixing seat in the capacitor housing. When the core needs to be taken out, the card plate is pushed out of the card slot by pushing the card plate. At this time, the fixing seat and the core can be pulled out of the capacitor housing by pulling the plate, thereby facilitating the installation or removal of the core.

[0015] 2. The No. 1 and No. 2 heat conducting plates on the heat dissipation device are installed at both ends of the core respectively, which can quickly conduct the heat in the core to the graphite heat sink. The graphite heat sink has a unique grain orientation and conducts heat evenly in two directions. The lamellar structure can adapt well to any surface, thereby quickly conducting heat to the chip and increasing its service life. BRIEF DESCRIPTION OF THE DRAWINGS
