Heat dissipation type anti-seismic aluminum electrolytic capacitor

Abstract

The invention relates to a heat dissipation type anti-seismic aluminum electrolytic capacitor which comprises a cover plate, a shell, an element and a lead. The cover plate is characterized in that protrusions are symmetrically arranged on the upper end face of the cover plate with respect to the center of the cover plate, and a wall part is arranged on the lower end face of the cover plate in the circumferential direction; the diameter of the inner circumference of the wall part is matched with the diameter of the outer circumference of the element; the outer peripheral surface of the wall part is propped against the inner peripheral surface of the shell; the joint of the wall part and the cover plate is positioned below the girdling groove; one end, connected with the lead, of the element is sleeved and fixed in the wall part to form a whole; the end, away from the cover plate, of the element is sleeved with an annular piece. The height of the protrusion is larger than that of the plain waist part, and when the protrusion is installed on the circuit board, a gap is formed between the plain waist part and the circuit board. Through the arrangement of the cover plate structure, the capacitor is firmly installed and rapidly dissipates heat, the heat dissipation performance and the shock resistance of the aluminum electrolytic capacitor are improved, and the purposes of high temperature resistance and stability are achieved.

Description

technical field [0001] The invention belongs to the field of capacitors, in particular to a heat dissipation type shockproof aluminum electrolytic capacitor. Background technique [0002] Capacitors are one of the electronic components widely used in electronic equipment and are an essential part of circuits. Due to the development of electronic science and technology, electronic products are developing in the direction of high frequency, miniaturization, and high reliability, and the requirements for the anti-seismic performance of capacitors, especially the heat dissipation performance, have been improved. For the current common capacitors on the market, especially those used in new energy vehicles, and lack of anti-seismic and heat dissipation structures, the capacitors are prone to shaking or broken pins during the moving process of the car, and the heat generated by the capacitors cannot be dissipated in time. Therefore, it is easy to cause damage to the components ins...

For the current common capacitors on the market, especially those used in new energy vehicles, and lack of anti-seismic and heat dissipation structures, the capacitors are prone to shaking or broken pins when the car is moving, and the heat generated by the capacitors cannot be dissipated in time. It is easy to cause damage to the components inside the capacitor and damage to the outside of the capacitor, thus affecting its overall service life
