Embodiment Construction

[0012] The two module main boards of the present invention are respectively packaged in two housings, and the A module and the B module of the split structure are connected by connectors (CZ1, CZ2) at both ends of the multi-core flat wire, and the power supply is turned on during use, (R6 ) to charge (C1), and when it is charged to a certain voltage, the integrated circuit (ICI) starts to work, and the output pulse pushes the switch tube (Q1) to be turned on and off, and the pulse signal is fed back through the transformer (B1) and the DC blocking capacitor (C9) To the secondary pole, all the way is rectified by the diode (D3), filtered by the capacitor (C2), and after the voltage is stabilized by the triode (Q2), bias resistor (R3), and voltage regulator (D2), it provides the power required for the operation of the integrated circuit (IC1) .

[0013] The other channel passes through (D4) and (C3) for voltage stabilization and sampling, and the potentiometer (W1) adjusts the s...

Abstract

This invention discloses one plus one switch power module, which comprises two module main boards sealed into two shells with structure A and B connected by multi-core flat wire, wherein, the A module is set with indication function diode with feedback isolation capacitor on left and with stable adjusting level device on right and special bus circuit, resistance on left; the B module is set with switch tube with gray control wire on down part and red control wire and black control line.

Description

technical field [0001] The invention relates to a switching power supply module for televisions, VCDs, DVDs, satellite receivers, etc., in particular A module and B module with split structure, which are connected by connectors (CZ1, CZ2) at both ends of multi-core flat wires. technical background [0002] At present, the known TV power supply modules are all single modules. The TV power supply modules are taken from the secondary power supply and have no voltage regulation. Inconvenient, there is no indicator light, it is difficult to show its working status. Contents of the invention [0003] In order to overcome the technical deficiencies of the existing TV, VCD, DVD, and satellite receiver power supply modules, the present invention provides a 1+1 split switching power supply module, the 1+1 split switching power supply module is composed of split structure Module A and module B are connected by connectors (CZ1, CZ2) at both ends of multi-core flat wires. The IC worki...
