[0001] The utility model relates to the technical field of capacitors, in particular to a high-efficiency and energy-saving vehicle-mounted capacitor. Background Art

[0002] A capacitor is an electronic component that stores electrical energy and is widely used in circuits. It consists of two plates and an insulating material. When voltage is applied between the two plates of the capacitor, the capacitor will store charge. The main function of the capacitor is to store charge and energy and release it when needed. One type of capacitor is an electrolytic capacitor used in vehicles. When using an electrolytic capacitor, the electrolytic capacitor needs to be installed on the circuit board in the car.

[0003] The above-mentioned and existing technologies have the following defects: a large amount of heat is generated during the operation of the electrolytic capacitor. Since the heat is difficult to dissipate, the temperature of the electrolytic capacitor increases, and the capacitance value of the electrolytic capacitor decreases with the increase in temperature, which in turn leads to a decrease in the working efficiency of the electrolytic capacitor and wastes energy.

[0004] Therefore, a high-efficiency and energy-saving vehicle-mounted capacitor is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that a large amount of heat is generated during the operation of the electrolytic capacitor, and the temperature of the electrolytic capacitor increases due to the difficulty in dissipating the heat, and to propose a high-efficiency and energy-saving vehicle-mounted capacitor.

[0006] In order to achieve the above-mentioned purpose, the present utility model adopts the following technical solution: a high-efficiency and energy-saving vehicle-mounted capacitor, including a capacitor body, the surface of the capacitor body is electrically connected to a pin, the surface of the capacitor body is fixedly connected to a heat spreader ring, the arc surface of the heat spreader ring is fixedly connected to a plurality of heat sinks, the surface of the heat sink is fixedly connected to a heat sink ring, and the heat spreader ring, heat sink and heat sink ring are all made of copper alloy.

[0009] The effect achieved by the above components is that the protective cover can shield the pins to prevent the pins from being hit and bent or even broken.

[0010] Preferably, the arc surface of the protective sleeve is provided with two through holes.

[0011] The effect achieved by the above components is that the through hole can increase the friction of the arc surface of the protective cover, making it easier to move the protective cover.

[0012] Preferably, a clamping sleeve is fixedly connected to the arc surface of the protective sleeve, and the clamping sleeve is clamped and connected to the heat equalizing ring.

[0013] The effect achieved by the above components is that when the ferrule is engaged with the heat-saturating ring, the ferrule can further limit the position of the protective sleeve and improve the firmness of the protective sleeve.

[0014] Preferably, a magnetic ring is fixedly connected to the inner wall of the protective sleeve, and the magnetic ring abuts against the arc surface of the clamping ring, and the clamping ring is an iron ring.

[0015] The effect achieved by the above components is that after the magnetic ring contacts the clamping ring, the magnetic ring will be attracted to the arc surface of the clamping ring, thereby preventing the clamping ring from losing contact with the protective sleeve.

[0016] Preferably, an insulating pad is fixedly connected to the surface of the capacitor body, the lower end of the insulating pad is lower than the lower end of the clamping ring, and the pin passes through the insulating pad.

[0017] The effect achieved by the above components is that the insulating pad can prevent the iron clamping ring from contacting the circuit on the circuit board, thereby affecting the normal operation of the circuit board.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figures 1-4 As shown, the utility model provides a high-efficiency and energy-saving vehicle-mounted capacitor, including a capacitor body 1, the surface of the capacitor body 1 is electrically connected to a pin 2, the surface of the capacitor body 1 is fixedly connected to a heat-sinking ring 3, the arc surface of the heat-sinking ring 3 is fixedly connected to a plurality of heat sinks 4, the surface of the heat sink 4 is fixedly connected to a heat sink ring 5, the heat-sinking ring 3, the heat sink 4 and the heat sink ring 5 are all made of copper alloy, and the heat-sinking ring 3, the heat sink 4 and the heat sink ring 5 cooperate with each other to effectively improve the heat dissipation performance of the capacitor body 1, prevent the working efficiency of the electrolytic capacitor from decreasing, and thus save energy, the surface of the capacitor body 1 is fixedly connected to a clamping ring 6, the arc surface of the clamping ring 6 is clamped and connected to a protective sleeve 7, the inner wall of the protective sleeve 7 is fixedly connected to two partitions 8, the pin 2 is located between the two partitions 8, and the protective sleeve 7 can shield the pin 2 to prevent the pin 2 from being hit and bent or even broken.

[0028] like Figures 1-4 As shown, the arc surface of the protective sleeve 7 is provided with two through holes 9, which can increase the friction of the arc surface of the protective sleeve 7 and facilitate the movement of the protective sleeve 7. The arc surface of the protective sleeve 7 is fixedly connected with a clamping sleeve 10, which is engaged with the heat-soaking ring 3. When the clamping sleeve 10 is engaged with the heat-soaking ring 3, the clamping sleeve 10 can further limit the position of the protective sleeve 7 and improve the firmness of the protective sleeve 7. The inner wall of the protective sleeve 7 is fixedly connected with a magnetic ring 11, which is against the arc surface of the clamping ring 6. The clamping ring 6 is an iron ring. After the magnetic ring 11 contacts the clamping ring 6, the magnetic ring 11 will be sucked on the arc surface of the clamping ring 6, thereby preventing the clamping ring 6 from losing contact with the protective sleeve 7. The surface of the capacitor body 1 is fixedly connected with an insulating pad 12, and the lower end of the insulating pad 12 is lower than the lower end of the clamping ring 6. The pin 2 passes through the insulating pad 12. The insulating pad 12 can prevent the iron clamping ring 6 from contacting the circuit on the circuit board, affecting the normal operation of the circuit board.

[0029] Its overall working principle is that before installing the capacitor body 1, the protective sleeve 7 can shield the pin 2 to prevent the pin 2 from being hit and bent or even broken. After the magnetic ring 11 contacts the clamping ring 6, the magnetic ring 11 will be sucked on the arc surface of the clamping ring 6, thereby preventing the clamping ring 6 from being out of contact with the protective sleeve 7. When the clamping sleeve 10 is engaged with the heat-saturating ring 3, the clamping sleeve 10 can further limit the position of the protective sleeve 7 and improve the firmness of the protective sleeve 7. When the capacitor body 1 needs to be installed on the circuit board of the vehicle again, the protective sleeve 7 is removed with the help of the through hole 9, and then the pin 2 is welded to the circuit board. At this time, the insulating pad 12 will contact the circuit board, and the insulating pad 12 can prevent the iron clamping ring 6 from being out of contact with the circuit board. The circuit contact on the circuit board affects the normal operation of the circuit board. During the operation of the on-board capacitor body 1, the heat-sinking ring 3 can absorb the heat in the capacitor body 1 in time, cool the capacitor body 1, and prevent the capacitance value of the capacitor body 1 from decreasing. Then the heat-sinking ring 3 will transfer the heat to the heat sink 4, and the heat sink 4 will transfer the heat to the heat dissipation ring 5. The heat sink 4 and the heat dissipation ring 5 can increase the contact area with the air, thereby facilitating the conduction of heat into the air. Through the cooperation of the heat-sinking ring 3, the heat sink 4 and the heat dissipation ring 5, the heat dissipation performance of the capacitor body 1 can be effectively improved, and the working efficiency of the capacitor body 1 can be prevented from decreasing, thereby saving energy.
