Abstract
The utility model relates to a computer key board power lead-out commutator. A power lead-out commutator is arranged between the interface of a computer keyboard and the plug of the keyboard. The commutator is composed of the plug, a socket, and two groups of conductor wires. The utility model has the advantages of simple structure and convenient operation and is used for the peripheral equipment of a computer with less power consumption.
Description
The utility model relates to a kind of computer keyboard power supply and draws breakout box, belongs to the computer fittings field.
The external unit of computing machine is as printer etc.Need power supply to work, but the equipment that has, fairly simple as the intelligence printer shared device, power consumption is fewer, if stabilized voltage supply of specialize, the one, the cost height, the 2nd, can not join portable machine and use in the open air; If use battery, then require whole external device circuitry power consumption minimum, still feel inconvenience during use.
The purpose of this utility model is that design computer keyboard power supply convenient and practical, that can do little electric current external unit power supply use is drawn breakout box.
For achieving the above object, the design that the utility model adopted is: power supply is installed between computer keyboard interface and keyboard plug is drawn breakout box, breakout box is by plug, and socket and two groups of leads are formed.
Now in conjunction with the accompanying drawings the utility model is further described: accompanying drawing is the utility model syndeton synoptic diagram
As shown in the figure, at computer keyboard interface 1 place installation plug 2 correspondingly, 5 pin round plugs for example, at keyboard plug 5 places installation socket 4 correspondingly, 5 hole circle sockets for example, between plug 2 and socket 4, be communicated with whole lines that computing machine is sent into keyboard with one group of lead 3, lead 6 and two wires attaching plug 7 are installed on power supply in lead 3 and the ground wire, lead 6 can directly be welded on the power supply and earth terminal of plug 2 afterbodys, also can directly be welded on the power supply and earth terminal of socket 4 afterbodys.
The utility model can be used for the various device of power consumption less than 400mA, as external Hanzi board, intelligence printer shared device, circumscribed modulator-demodular unit, outside network interface card, circumscribed FAX, programmable device, single card microcomputer, the instrument and meter that power consumption is less, one-chip computer developing system, computer speech system computer music system etc., the utlity model has simple in structurely, convenient use low cost and other advantages.
