Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of diodes, in particular to an axial diode. Background Art
[0002] A diode is an electronic device made of semiconductor materials. It has two electrodes, a positive electrode and a negative electrode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on. When a reverse voltage is applied, the diode is cut off. The conduction and cutoff of the diode are equivalent to the on and off of a switch. An axial diode is a diode with legs at both ends. It is a discrete component and its main application is rectification, which only allows current in one direction to pass through.
[0003] When the axial diode is in use, electricity is passed between the two leads to generate current, release heat, and the temperature inside the shell rises. Most of the common axial diodes on the market have poor heat dissipation effects, and the leads passing through the shell lack protective devices near the shell, which are easily bent during use. Since the leads near the shell are close to the electrodes, they are easy to affect the electrodes when bent, causing damage to the entire axial diode. Therefore, an axial diode is proposed to address the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

The first heat sink provided inside the shell enables the inside of the shell to have a heat dissipation effect.
[0013] The first protective shell, the second protective shell, the rubber layer and the reinforcing strip are provided to effectively protect the diode lead wire near the electrode, making it difficult to bend. The rubber layer is provided to increase the protective effect. The reinforcing strip is provided in the rubber layer to further increase the protective effect of the diode lead wire.
