The position of internal heat dissipating chamber.
Further, the shielded layer is made of epoxy resin.
Through the above technical solutions, epoxide resin material easily obtains, and electromagnetic shielding performance is good, for improving metal tape
Shielding properties.
Further, the metal tape two sides equidistantly offer index aperture, and the shielded layer is located at the adjacent mark
Remember between hole.
Through the above technical solutions, opening up index aperture is not only convenient for the Position Approximate that user understands heat dissipation cavity, meanwhile, just
It is fixed in by the position of metal tape, is convenient for punch forming.
Further, the heat dissipation cavity is made of a plurality of criss-cross channel.
Through the above technical solutions, both can ensure that metal tape had certain intensity by opening up staggered channel, moreover it is possible to
Realize the function of heat dissipation.
Further, the thermovent is located at the intersection in the channel.
Through the above technical solutions, thermovent is provided with channel intersection, it is real convenient for receiving the gas discharge of heat in channel
The cooling of existing metal tape.
Further, the metal tape is made of stainless steel or foreign white copper.
Through the above technical solutions, the intensity of stainless steel or foreign white copper is high, thermal conductivity is good, moreover it can be used to shield electromagnetism letter
Number.
Compared with prior art, the utility model has the beneficial effects that
(1) by opening up heat dissipation cavity and thermovent, metal tape absorbs the heat that component work generates, then passes heat
It is handed in radiating groove, the gas in radiating groove is heated to be overflowed, to reduce the temperature of metal tape, realizes the guarantor to internal component
Shield；
(2) further, being coated with shielded layer made of epoxy resin on metal tape, the screen of metal tape can be enhanced
Cover performance, moreover it can be used to mark the position of metal tape internal heat dissipating chamber；
(3) further, by opening up index aperture, can person easy to process understand the position of metal tape internal heat dissipating chamber,
