Abstract
The utility model is a multi-digit multisource self-lock electronic power switch specially used by home cinemas, and consists of a panel and a power switch circuit. A plurality of power switch buttons is arranged on the panel. The utility model is characterized in that the power switch circuit is composed of an integrated package IC1(CD4017), which includes a capacitance C1, a resistance R1,a resistance R2, a triode BG1, a electric relay J1, a capacitance C2, and a diode D1. The utility model solves the problem of normal use of the main electric power source which controls every acoustic and image device of the home cinema, thus resulting that every control switch button can be placed arbitrarily, and being conducive to the arrangement of the whole panel at the same time.
Description
The utility model relates to a kind of electronic switch, refers in particular to power supply specially for household cinema multidigit self-locking electronic switch.
The colour TV of using always in the subscriber household, video tape recorder, VCD (little video disc player), LD (big video disc player), CD (compact disc player), DVD (little video disc player), sound equipment, AV household electrical appliances audio-visual equipments such as (power amplifiers), often form a more complete household audio and video system, interconnecting in the configuration of external power supply (220V) and signal line, can not accomplish flexibly, rationally, scientifically to connect fast and switching controls, make the household electrical appliances audio-visual equipment can not give play to the effect of application.General electronic switch is interlocking-type, is used in above the AV of home theater as the diverter switch of source of sound, and this is because the input source of sound of AV can only be a kind of, rather than several.But as home theater, must control and switch many audio and video equipments, therefore general Mutual-Lock Electronic Switch can't resolve this problem.
The purpose of this utility model is to provide a kind of power supply specially for household cinema multidigit self-locking electronic switch, can control the main power source of each audio-visual equipment in the home theater respectively separately, normally uses simultaneously.
For achieving the above object, the solution that the utility model is taked is: a kind of power supply specially for household cinema multidigit self-locking electronic switch, comprise panel and switching circuit, panel is provided with a plurality of shift knobs, be characterized in that switching circuit is made up of ic chip 1,1 one pin of ic chip meet shift knob AN1 by the series connection mid point of capacitor C 1 and resistance R 1, a pin connects triode BG1 base stage by resistance R 2, a pin connects power positive end, two pin connect power supply negative terminal, two pin mutual connections, capacitor C 1 positive pole connects power positive end, the negative terminal of resistance R 1 another termination power, the emitter of triode BG1 connects power supply negative terminal, collector connecting relay J1, the negative pole of capacitor C 2, diode D1, relay J 1, capacitor C 2 positive poles, another termination power positive end of diode D1.
The utility model has solved the main power source of each audio-visual equipment of control home theater and the normal simultaneously problem of using makes each control switch button to place arbitrarily, helps the layout of whole front panel simultaneously.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is the electrical schematic diagram of present embodiment switching circuit.
Fig. 2 is the panel arrangement schematic diagram of present embodiment.
In Fig. 1, n represents a plurality of push-button switches.Present embodiment adopts ic chip 1 (CD4017) to form 8 self-locking electronic switch, can distinguish the main power source of controlling radio reception, satellite TV, subwoofer, preposition, TV, DVD, power amplifier, decoder separately.In Fig. 2, shift knob the 2,3,4,5,6,7,8, the 9th, the shift knob of radio reception head, preposition, decoder, satellite TV, subwoofer, power amplifier, DVD, TV.
As depicted in figs. 1 and 2, a kind of power supply specially for household cinema multidigit self-locking electronic switch, comprise panel 1 and switching circuit, panel 1 is provided with a plurality of shift knobs 2,3,4,5,6,7,8,9, be characterized in that switching circuit is made up of ic chip 1,1 one pin of ic chip meet shift knob AN1 by the series connection mid point of capacitor C 1 and resistance R 1, a pin connects triode BG1 base stage by resistance R 2, a pin connects power positive end, two pin connect power supply negative terminal, two pin mutual connections, capacitor C 1 positive pole connects power positive end, the negative terminal of resistance R 1 another termination power, the emitter of triode BG1 connects power supply negative terminal, collector connecting relay J1, the negative pole of capacitor C 2, diode D1, relay J 1 other end, capacitor C 2 positive poles, another termination power positive end of diode D1.
