Detailed Description

The invention will be further described with reference to the following drawings and detailed description:

in the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example (b): as shown in fig. 1-4: a power adapter with protection, comprising: casing 1, casing 1 comprises last casing 11 and lower casing 12, go up casing 11 with casing 12 can dismantle to link together and constitute airtight space down, it is square with casing 12's shape down to go up casing 11, just go up casing 11 and be equipped with lower casing 12 surperficial four bight symmetries bellying 13, bellying 13 play the supporting role to casing 1, when casing 1 places in the desktop, casing 12 sets up the undercut 14 in addition down, and leave more spaces between 2 the desktop and be convenient for the bottom heat dissipation of casing 1. In addition, when the shell 1 is turned over, the upper shell 11 still has the convex part 13 to play a supporting role, and in addition, the downward concave part 41 arranged on the surface of the upper shell 11 still can play a role that the shell 1 does not directly contact the desktop 2, and a gap is reserved to facilitate heat dissipation.

Particularly, the junction of the upper shell 11 and the lower shell 12 is provided with a sealing colloid 21, the upper shell 11 and the lower shell 12 are bonded together through the sealing colloid 21, the surfaces of the upper shell 11 and the lower shell 12 are respectively provided with four protrusions 13, the upper shell 11 and the lower shell 12 are both provided with inward recesses, the lower shell 12 in the sealed space is provided with a PCB 15, a heat conducting block 16 and a heat conducting gasket 17, and rubber protection rings 18 are fixedly arranged on two sides of the lower shell 12, so that the cable 3 at the junction of the lower shell 1 can be better ensured not to be damaged and broken easily.

Specifically, the lower case 12 is further provided with a plurality of heat dissipation holes 19, and the heat dissipation holes 19 are opened in a recessed area 20 of the lower case. The heat conduction block 16 is arranged between the PCB 15 and the heat conduction gasket 17, the heat conduction block 16 is arranged on the bottom surface of the PCB 15, the heat conduction block 16 is made of iron, heat conductivity is improved, and heat generated by the PCB 15 can be better conducted to the heat conduction gasket 17.
