Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

(embodiment 1)

See Fig. 1 and Fig. 2, the good Switching Power Supply of insulation effect of the present embodiment, it is mainly made up of shell 1, circuit arrangement and heat radiation pressing plate 3 and insulation heat conduction casing pipe 4.

Shell 1 is mainly made up of upper cover 11 and base 12. Base 12 is made up of base plate 12-1 and 2 side plate 12-2 one, and 2 side plate 12-2 are each respectively in the upper end, the left and right sides of base plate 12-1 arranges 1. While installing, upper cover 11 is fastened on the upper end of base 12 and is screwed connection. The material of shell 1 is the aluminium easily dispelling the heat.
