Abstract
The utility model relates to a multi-channel video signal converter, which is composed of a female interface, male interfaces and conducting wires. The utility model is characterized in that the multi-channel video signal converter is provided with one female interface, at least two male interfaces and the corresponding wires, wherein, converting switches can be arranged at the mutual connecting part of the corresponding wires, or all the corresponding wires can be connected to the female interface. The utility model has the advantages simple structure, low cost and convenient operation, and is mainly used for demonstrating and teaching in computer network classrooms. With the multi-channel video signal converter, a single display can respectively receive the video signals from a plurality of host machines.
Description
The utility model relates to a kind of circuit transducer, particularly a kind ofly can make a display can receive video-frequency signal converter from many main frames respectively.
Present computer network apparatus for demonstrating, the display that makes that has only has demo function, though the vision signal that can make display difference reception server and this main frame that has, but its complex structure, components and parts are many, the cost height, fragile, this is the deficiency of existing frequency divider.
The purpose of this utility model provides a kind of computer multi-channel video signal transducer, this transducer can make a display receive vision signal from multiple host respectively, when computer network teaching, the display on every student's machine not only can receive the vision signal of this machine, behind this machine-operated machine, can receive the vision signal that teacher computer is sent here again, simple with existing frequency divider structure compared, simple and easy practicality, cost is low, not fragile, in order to overcome existing deficiency with frequency divider.
The purpose of this utility model can realize by following embodiment: the utility model is by maternal interface, public access mouth and lead constitute, be characterized in having on it maternal interface in order to be connected with display, there are two, three, four or a plurality of public access mouth are in order to be connected with main frame and corresponding line arranged, maternal interface, the public access mouth is the device with two locking ears, on the locking ear step through-hole is arranged, the bore dia that is the front is thin, the bore dia of back is thick, band step and threaded taper pin are arranged on this through hole, there is embossing to twist handle behind the taper pin, so that turn stubborn handle after plugging, the locking maternal interface, the public access mouth.The place of interconnecting of corresponding line of this transducer can establish change over switch, or with corresponding line and receive on the maternal interface.
The utility model also can be by in the vision signal input of display directly and connect a plurality of public access mouths and realize.
Advantage of the present utility model is: simple in structure, cheap, easy to use, this transducer is mainly used in the demonstration and the teaching in computer network classroom, use this transducer, a display of microcomputer classroom student's machine can also receive other computer respectively, mainly be meant the vision signal of teaching machine except that the signal that receives this main frame, be a kind of desirable multi-channel video signal transducer.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the overall structure figure of line band change over switch
Fig. 2 is the overall structure figure of line band multichannel interface
Fig. 3 is for directly in the vision signal input of display and meet the overall structure figure of a plurality of public access mouths
As Figure 1-3, this transducer is made of maternal interface 1, public access mouth 2 and lead 3, be characterized in having on it maternal interface 1, two, three, four or a plurality of public access mouth 2 and corresponding lead 3 are arranged, maternal interface 1, public access mouth 2 are the device with two locking ears 4, on the locking ear 4 step through-hole 5 is arranged, the bore dia that is the front is thin, the bore dia of back is thick, band step and threaded taper pin are arranged on this through hole, there is embossing to twist handle 6 behind the taper pin, so that turn stubborn handle after plugging, locking maternal interface 1, public access mouth 2.The place of interconnecting of corresponding line 3 of this transducer can establish change over switch, or with corresponding line 3 and receive on the maternal interface 1, change over switch can be realized with push switch 7.
The utility model also can be by in the vision signal input of display directly and connect a plurality of public access mouths and realize.
