Description
[technical field]
The relevant a kind of electromagnetic wave proof electroconductive elastic sheet of the utility model, especially a kind of being applied on the case of electronic device leaks to the electroconductive elastic sheet of case of electronic device outside in order to prevent electromagnetic interference.
[background technology]
Electromagnetic interference (EMI, Electro Magnetic Interference) protection is very important safety pointer of electronic product, with the computer is example, microprocessor (CPU) is the source of the electromagnetic interference of its inner maximum, along with the arithmetic speed of microprocessor is more and more faster, the electromagnetic interference that it produced is also more serious.
General computer is to the design of electromagnetic interference shielding, be with conductive material as the main structure body, and electromagnetic interference is closed in the inside of whole computer, so the casing of general computer mostly is metal material greatly.And promptly be similarly to be notebook computer or personal digital assistant ... Deng the handheld apparatus that must use more frivolous plastic casing, also can within shell, spray conductive materials such as conductive paint by face usually, as the barrier of the electromagnetic interference of blockading.
Yet; casing with general computer is an example; it is combined by many metal plate work pieces usually; as shown in Figure 1; two plate work pieces 100,200 can exist because of combined tolerances has a slit d1 when combination usually, and this slit d1 can cause two plate work pieces 100,200 can't contact formation really and electrically conduct; make electromagnetic interference leak to the external world from here, can not meet the requirement of safety.
The common practice is to form a shell fragment 110 with salient point 112 on a plate work piece 100 wherein, this shell fragment 110 can be when the punching press processing procedure directly and plate work piece 100 integrally formed.When two plate work pieces 100,200 were combined, the salient point 112 on the shell fragment 110 of plate work piece 100 can be contacted with another plate work piece 200, and guaranteed that by the elastic force of shell fragment 110 both can contact really, and formation electrically conducts, and realized the purpose of electromagnetic interference shielding.
; because shell fragment 110 is integrally formed with plate work piece 100; and plate work piece 100 sizes are bigger; above-mentioned structure needs to stamp out shell fragment 110 at plate work piece 100 lateral margins earlier in the punching press processing procedure; and then plate work piece 100 is provided with the lateral margin bending of shell fragment 110; the shortcoming of this kind mode is that its elasticity is not fine, and distortion excessively just is not easy resilience a little, and it is bad to cause contacting effect; The contact point that is exactly it in addition is fewer, and along with present computer cpu dominant frequency is more and more higher, this mode is EMI suppression radiation effectively.
The another kind of common practice is to paste a conducting foam (gasket) 300 on plate work piece 100, and as shown in Figure 2, it is held between two plate work pieces 100,200, can reach the purpose that both are electrically conducted equally.
Yet, the costing an arm and a leg of conducting foam 300, and aging easily follow the string, change difficult.
In view of this, be necessary in fact to provide a kind of electromagnetic wave proof electroconductive elastic sheet that is easy to make, be easy to be assembled on the case of electronic device.
