The multifunctional notebook computer socket

Technical field

The utility model relates to the multifunctional notebook computer socket that a kind of suitable power line modem uses, and mainly makes things convenient for other external device such as electrification line modem and portable hard drive on the notebook computer.

Background technology

Because power line spreads all over city, rural area and family, its coverage rate is that any other network is incomparable, therefore utilize power line modem to pass through the power line transmission data, can not need to set up under more circuit and the equipment situation, only needing that modulator-demodulator is inserted power receptacle just can communicate, it uses simple, and is with low cost, helps information resources and shares and the household electrical appliances online.Along with a large amount of uses of notebook computer, its network access is mainly wired and wireless two kinds in addition.It is exactly wherein a kind of mode that notebook computer utilizes power line communications, and we make things convenient for notebook computer to utilize power line communications by this multi-function jack of design exactly.

The utility model content

The technical problems to be solved in the utility model is: the multifunctional notebook computer socket that provides a kind of suitable power line modem to use, make things convenient for the notebook computer user to pass through power line communications, the defective of electricity shortage in the time of also can solving part notebook computer use portable hard drive and other external device simultaneously.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of multifunctional notebook computer socket, comprise jack body, one end of described jack body is provided with position, the three holes male seat end in position, the three holes female seat end of the power supply adaptor that can directly insert notebook computer, and the other end of jack body is provided with position, the three holes female seat end that can directly be connected with the 220V power line of position, three holes male seat end; The surface of described jack body has a plurality of universal power sockets and status indicator lamp, and a side of jack body is provided with external apparatus interface; Position, described three hole male seat end, position, three holes female seat end, universal power socket, status indicator lamp and external apparatus interface are each other for being electrically connected.

Further, in order to meet most of users' use habit, external apparatus interface described in the utility model is standard USB interface and/or mini-USB interface.

The utility model one end is in position, the three holes female seat end of position, the three holes male seat end power supply adaptor that can directly insert notebook computer, makes whole socket become conduction type with power supply adaptor; The other end is position, three a holes female seat end, can directly be connected with the 220V power line of position, three holes male seat end.Connect the 220V power supply, the socket status indicator lamp is lighted.

The beneficial effects of the utility model are, have solved the defective that exists in the background technology, make things convenient for the notebook computer user to pass through power line communications, the defective of electricity shortage in the time of also can solving the part notebook computer simultaneously and use portable hard drive and other external device.

Embodiment

With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

A kind of multifunctional notebook computer socket shown in Fig. 1～5, comprise jack body 1, one end of described jack body 1 is provided with position, the three holes male seat end 11 in position, the three holes female seat end of the power supply adaptor that can directly insert notebook computer, and the other end of jack body 1 is provided with position, the three holes female seat end 12 that can directly be connected with the 220V power line of position, three holes male seat end; The surface of described jack body 1 has a plurality of universal power sockets 13 and status indicator lamp 14, and a side of jack body 1 is provided with external apparatus interface; Position, described three hole male seat end 11, position, three holes female seat end 12, universal power socket 13, status indicator lamp 14 and external apparatus interface are each other for being electrically connected.

Shown in Fig. 6,7, operation principle of the present utility model and work engineering are:

The transformer input connects attaching plug through an insurance, if the circuit of transformer or back is short-circuited, the filament in the insurance will dissolve the back because of the high temperature that high-current leading is sent out and disconnect.A bridge rectifier is formed by 4 diodes in the transformer back, just obtains a DC power supply that voltage fluctuation is very big after the rectification, so connect the electrochemical capacitor of a 330uF/25V again.The 9V voltage of transformer output is through bridge rectifier and capacitor filtering, approximately have the more voltage of 11V at capacitor C 1 two ends, if directly connect a load from the electric capacity two ends, when having a little fluctuation, load variations or AC power all can make the voltage at C1 two ends that by a relatively large margin variation takes place, therefore to obtain a more stable voltage, connect the element of a three terminal regulator here.Three terminal regulator is a kind of integrated circuit component, inside is made of some triodes and resistance etc., can think simply that when analysis circuit this is the element that can regulate resistance automatically, resistance when load current is big in the three terminal regulator diminishes automatically, and the resistance in the three terminal regulator can become greatly automatically when load current diminishes, and so just can keep the output voltage of pressurizer to keep constant substantially.

Because export the voltage of 5V, so select for use the letter of 7805,7805 fronts may be different different because of manufacturer.The LM7805 maximum can be exported the electric current of 1A, and there is the current-limiting type short-circuit protection inside, and in the short time, for example the time in several seconds, output (2 pin) short circuit over the ground can't make 7805 to burn out, and actual the use generally do not surpass 500mA.Need finned if surpass.The three terminal regulator back connects one 105 electric capacity, and this electric capacity has filtering and damping action.At last 2 liang of capacitor C are terminated on the power supply bipod of USB.

What describe in the above specification is embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of utility model.
