Convenient-to-install high-electrical-performance power panel for digital television set top box and installation method

Abstract

The invention discloses a convenient-to-mount high-electrical-performance power panel for a digital television set top box, which comprises an outer shell, a display module is embedded in one side of the front end surface of the outer shell, a control button is embedded in the other side of the front end surface of the outer shell, a sliding rail is fixedly connected to one side of the inner wall of the outer shell, and a sleeve is slidably connected to the surface of the sliding rail in a sleeving manner. According to the invention, when the current control module electrifies the power panel module through the connecting line for operation, the current control module and the power line of the external power supply end can monitor the current in the power line in real time through the current detection module sleeved on the surface and transmit the current value to the PLC control module, and the threshold value of the current value is preset in the PLC control module. When the current is larger than a threshold value, a program is preset in the PLC control module to control the current control module and change the current, and the situation that overlarge current is directly input into the power panel module, components in the power panel module are broken down, and the power panel module is damaged can be prevented.

Description

technical field [0001] The invention relates to the technical field of set-top box power board equipment, in particular to a power board with high electrical performance and an installation method for a portable digital TV set-top box. Background technique [0002] The movement transmission mechanism of the DVD includes a sliding rack installed on the main frame of the movement. The sliding rack cooperates with the gear on the main frame of the device movement. Drive the sliding rack to move, thereby lifting the laser head up until the disc is lifted to the normal playing position, so as to read the information on the disc through the laser head. [0003] The existing portable digital TV set-top box uses a power board with high electrical performance. During its use, the power board is usually fixed in the upper and lower housings by several bolts, and then directly connected to the external power line for power-on operation. However, this method is easy to operate. Under t...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the existing power board with high electrical performance for the portable digital TV set-top box. During its use, the power board is usually fixed in the upper and lower housings by several bolts, and then the power cord is directly connected externally. However, in this way, it is easy to be affected by excessive current, break down the components in the power board, and has the disadvantages of troublesome disassembly and assembly in the later maintenance, and a high electrical performance power board for portable digital TV set-top boxes is proposed. and installation method
