Background

With the advent of the information-oriented era, the interconnection of everything has become a great industry development trend. Among them, the importance and attention of wireless signal transmission are increasing, and wireless products are divided into a plurality of kinds according to power, and most common are home routers and commercial routers.

Along with the increase to wireless signal quality requirement, consequently the increase of router power to the router produces more heats, concentrates on the router the inside, and in order to dispel the heat to the router, the side of router shell can be provided with the louvre, and the heat dissipation of being convenient for, in addition because of the consideration of safety, the size of louvre can receive the trade specification restriction (about 0.8mm at present), under the circumstances that can not add the hole diameter, the design of louvre just becomes especially important.

The heat dissipation hole and the wiring interface of the router are designed on the same side, the distance between the two holes is only the thickness of a product wall, the wiring interface outputs the wiring outwards, the heat of the heat dissipation hole is released outwards from the inside, and the angle direction of the heat dissipation hole is large in the inside and small in the outside, so that the heat dissipation hole and the wiring hole are opposite in direction.

In actual production, in order to process the shell of this type of router, need use the mould, the side of shell sets up the hole, has just become the back-off part on corresponding the mould, and because router itself is asymmetric, louvre and wiring hole position are because porose, hold tightly power big, because the opposite face in louvre and wiring hole is flat (do not have the hole), do not hold tightly power again, consequently the router shell is different to the power of holding tightly of mould, the shell can remove to mould one side (the big side of holding tightly power) when leading to the drawing of patterns to can fish tail the shell of the router of processing.
