Embodiment 1

[0026] refer to Figure 1-4 , a self-opening and closing waterproof and heat-dissipating power adapter, including an insulating case 1, a heat dissipation port 3 is opened through the top wall of the insulating case 1, and a radiator 4 is installed in the heat dissipation port 3, and the insulating case 1 A plurality of air inlets 16 are symmetrically opened on the side wall, and a dust-proof net 2 is installed at the heat dissipation port 3 and the plurality of air inlets 16, and the dust-proof net 2 can prevent sundries and dust from entering the insulating housing 1;

[0027] The insulating housing 1 is provided with a protective mechanism, the protective mechanism includes a partition 8 installed horizontally in the insulating housing 1, the middle part of the partition 8 slides through and is provided with a sliding rod 6, and the upper end of the sliding rod 6 is fixedly supported by an elastic plate 5 , and the first spring 7 is connected between the elastic plate 5 and...

Embodiment 2

[0040] refer to Figure 5 The difference between this embodiment and Embodiment 1 is that: the end of each first sliding chamber 81 away from the corresponding exhaust port 11 is fixedly provided with a permanent magnet block 20, and the end of each slide plate 10 close to the permanent magnet block 20 is embedded. There is a second single-sided magnet 21, and there is a magnetic attraction force between the corresponding permanent magnet block 20 and the second single-sided magnet 21. Each first sliding cavity 81 is provided with a limit block, which is used for To limit the maximum sliding distance of the sliding board 10 , multiple rows of balls 22 are symmetrically arranged in each of the first sliding chamber 81 and the second sliding chamber 82 , and the sliding board 10 and the magnetic board 12 are in rolling contact with the balls 22 .

[0041] When the present embodiment is in use, the elastic force effect of the second spring 9 is replaced by the magnetic attraction...

Abstract

The invention discloses a self-opening and closing waterproof and heat-dissipating power adapter. A plurality of air inlets are symmetrically opened on the side wall, and dust-proof nets are installed at the cooling outlets and the plurality of air inlets. A protective mechanism is provided in the insulating housing, and the protective mechanism includes a The middle part of the partition is slidably provided with a slide bar, the upper end of the slide bar is fixedly supported by an elastic plate, and a first spring is connected between the elastic plate and the partition plate, and the lower end of the slide bar is fixed An inner wedge block is connected, two exhaust ports are symmetrically opened on the partition, and two first sliding cavities and two second sliding cavities are symmetrically opened in the partition. The invention not only has excellent waterproof effect, but also does not affect the heat dissipation effect of the heat sink in the power adapter under the condition of less splashing water.

Description

technical field [0001] The invention relates to the technical field of power accessories, in particular to a self-opening and closing waterproof and heat-dissipating power adapter. Background technique [0002] When the power adapter performs voltage conversion, there will be energy loss, and a small part of the lost energy will be converted into waves, and most of the rest will be converted into heat, which is the main reason for the heat of the power adapter. Components are easily affected by high temperature, such as increased conductor resistance, unstable transistor gain, and operating point drift, so power adapters should try to avoid working at high temperatures. [0003] Common heat dissipation methods for high-power power adapters are to increase heat dissipation ports and install radiators, but none of the above heat dissipation methods can use a closed casing, so the power adapter will lose its waterproof performance. When splashed water enters the interior of the...
