A remote control receiving inner shield device

Abstract

The utility model discloses a kind of remote control receiving inner shielding devices, including lead support and the shielding support of installation in the upside of lead support, the upside of lead support and located the downside of shielding support is provided with photodiode, the right side of photodiode is provided with signal processing chip, the upper end outer wall inside of shielding support and respectively close to left and right sides are all set up light-transmitting window, the inside of two the light-transmitting window is all provided with cross obscuration, by installing cross obscuration, by making more than one frame of horizontal direction and vertical direction each other interlaced and form the obscuration of cross structure, can be shielded from multiple directions to the front of photodiode, not only can directly shield noise, but also reduce the reflection of noise in device inside, shielding mode of traditional possibility exist shielding not comprehensive or shielding path single problem, and cross obscuration is through longitudinal and transverse interlaced, and shielding range is maximized in limited space.
