The embodiment of the application discloses antidetonation type aluminium electrolytic capacitor.
Example 1:
referring to fig. 1, the anti-shock aluminum electrolytic capacitor includes a case 1, a core 2 installed in the case 1, and a cover 4 for closing the case 1, wherein two pins 3 are connected to the core 2, and the two pins 3 both penetrate the cover 4 and extend to the outside of the case 1.
Be connected with elastic damping member 5 on the rubber cover 4, elastic damping member 5's inside cavity and both ends link up, and pin 3 wears to locate in elastic damping member 5 and can buckle in elastic damping member 5, and elastic damping member 5's one end fixed connection is in rubber cover 4, and during the installation condenser, elastic damping member 5's the other end fixed connection can be used for connecting on the electronic component of condenser on circuit board or other.
When the capacitor shakes or rocks, the elastic damping piece 5 can deform when the capacitor shakes or rocks, so that the vibration or the rock is buffered to play a damping role. And the length of the elastic shock absorption piece 5 in the maximum stretching state is smaller than the length of the pin 3 penetrating out of the capacitor, so that the pin 3 is always in an unstrained state, and the pin 3 is prevented from being broken by pulling.
In this embodiment, the elastic damping member 5 is an insulating rubber tube 51, one end of the insulating rubber tube 51 is fixedly adhered to the rubber cover 4, and the other end of the insulating rubber tube 51 can also be connected to a circuit board or other electronic components for connecting a capacitor by an adhering method.

When the spring 52 is stretched to a state of being able to automatically recover its deformation, the length of the spring 52 is smaller than the length of the pin 3 penetrating from the inside of the capacitor.
In this embodiment, the spring 52 is provided with two, and two pins 3 wear to locate respectively in two springs 52 to independently part two pins 3, avoid two pins 3 intertwine to connect and lead to the capacitor short circuit.
In order to improve the firmness of the spring 52, the two ends of the spring 52 are welded with the reinforcing rings 521, the surfaces of the reinforcing rings 521 are also coated with insulating coatings, the reinforcing ring 521 at one end of the spring 52 is welded on the rubber cover 4 to realize the fixed connection between the spring 52 and the capacitor, the reinforcing ring 521 at the other end of the spring 52 is welded on a circuit board or other electronic elements for connecting the capacitor, the connection area between the reinforcing ring 521 and the rubber cover 4 and the circuit board is larger, and therefore the connection of the spring 52 is firmer.
The implementation principle of the embodiment 2 is as follows: spring 52 has good shock attenuation effect, adopts two springs 52 to cooperate jointly and can cushion the horizontal shearing force and the longitudinal extension force that produce when shaking or rocking well to the condenser, protects pin 3 effectively, and spring 52 stops the back at vibrations or rocking and drives the condenser more easily and reset to initial position, and spring 52 life is longer in addition to spring 52 cost is lower, and processing technology is simpler.
