Embodiment
For the ease of further understanding the technical solution of the utility model, SD card device of the present utility model and the embodiment specific implementation that contains the equipment of SD card device are described in detail below in conjunction with accompanying drawing:
Shown in Fig. 2 a and Fig. 2 b, the SD interface arrangement comprises substrate (1) and substrate (2), the thickness of substrate (1) is 1.45mm, make required connection line with the technology of printed circuit board (PCB) above, the thickness of substrate (2) is 0.8mm, one end of the connection line on the substrate (1) is provided with hard contact (3), and hard contact 3 is gold-plated; At substrate (1) other end, promptly substrate (1) is gone up the other end of connection line, makes row's plated through-hole 4, and described plated through-hole is used to connect other equipment.
Substrate (2) is shorter than substrate (1), so that the hard contact (3) on the encapsulation metacoxal plate (1) exposes, provides the approach that is connected with the SD deck.
Substrate (2) is shorter than substrate (1), and substrate (1) and substrate (2) adopt heat pressing process to be packaged together, and the part that contracts in the substrate (2) makes substrate (1) form a step at the end that hard contact is arranged like this, and hard contact is located on the step.When this step inserts standard SD deck at this interface arrangement, can play spacing effect, prevent that the deck reed from producing expendable deformation under the pressure of this interface arrangement.
With the mobile TV receiver that contains the SD interface arrangement is example, in conjunction with the accompanying drawings the embodiment of the equipment that contains SD card device of 3 confessions carried of explanation the utility model:
As shown in Figure 3, in this embodiment, signal processing circuit is made in a circuit board top separately, and this signal processing module comprises antenna (10), low noise amplifier LNA (11), tuning chip (12), demodulation chip (15), SD interface translation circuit (16), electrostatic prevention circuit (17); The specific implementation of SD card device (19) is similar to the embodiment in the above-mentioned SD interface arrangement, just repeats no more at this.
As shown in Figure 3, the mobile TV receiver is received TV signal by antenna (10), and antenna (10) is the telescopic antenna of U wave band, and the TV signal that antenna receives is amplified through a LNA circuit (11), can reduce the noise figure of total system, be convenient to improve receiving sensitivity;
