Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to an over-current short-circuit temperature protection plate. Background Art

[0002] With the development of science and technology, more and more electrical devices have entered our daily lives, and circuit boards are an indispensable and important part of electrical devices. Once the circuit board is damaged, it may affect the normal use of the entire device. Many existing circuit boards are directly fixedly installed, lacking protection for the circuit board body. The circuit board may be damaged by collision. At the same time, the overall shaking of the device may also affect the accuracy of some components of the circuit board, and problems such as loose connections and component falling off may occur. Among them, the application number "CN201821553742.7" has a protective plate structure for protecting the circuit board, which is provided with a protective cover with heat dissipation holes. During the use of the device, the protective cover can provide anti-collision protection for the circuit board without affecting the heat dissipation effect of the circuit components. At the same time, the corner cotton pads between the protective cover and the mounting plate can effectively support and buffer the circuit board, further improving the protection effect of the device on the circuit board. However, there are still certain deficiencies in the use of the circuit board: the circuit board does not have a circuit protection structure, and the circuit board is often damaged when the current is overloaded or short-circuited, resulting in the circuit board being unable to be used normally.
