Abstract
The utility model relates to network terminal device. The network terminal device comprises a power source circuit and a working circuit capable of realizing main functions of the network terminal device. The power source circuit is connected with a network through a network cable, and receives electric energy from the network cable. The network terminal device further comprises an energy storage circuit which receives the electric energy from the power source circuit and performs charging; and a power source end of the working circuit is connected with the energy storage circuit. The network terminal device of the utility model can use a power source line of a network line to perform charging and provide power for a circuit, and does not need to be equipped with a battery; and therefore, the network terminal device is advantageous in environmental protection and reduction of equipment cost.
Description
Technical field
The utility model relates to network-termination device.
Background technology
The function of existing network terminal equipment is more and more, needs setting battery could realize its function.Using serondary lithium battery is comparatively energy-conservation mode, but not enough environmental protection, and has increased the cost that the user purchases machine.Use dry cell need buy new battery repeatedly, use inconvenience, and not environmental protection.
Summary of the invention
Based on this, be necessary to provide a kind of not setting battery can realize the network-termination device of function.
A kind of network-termination device, the operating circuit that it comprises power circuit and can realize the network-termination device major function.Described power circuit receives electric energy by netting twine and network connection from described netting twine.Described network-termination device also comprises the accumulator that receives electric energy and charging from described power circuit; The power end of described operating circuit links to each other with accumulator.
Concrete, described power circuit comprises that the alternating current with netting twine output is converted to galvanic rectification circuit, and the change-over circuit that described direct current is converted to predeterminated voltage.
Network-termination device of the present utility model can utilize the power line of network line to charge and circuit is powered, and need not to install battery on the equipment, environmental protection, reduction equipment cost.
Description of drawings
Fig. 1 is the circuit theory diagrams of the network-termination device of an embodiment.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model network-termination device is described in further detail.
Please refer to Fig. 1, the utility model network-termination device mainly comprises power circuit, accumulator and operating circuit.Operating circuit be for can realize the network-termination device major function, for example the circuit module of function such as phone, online.
Power circuit links to each other with the network interface of network-termination device, and it can link to each other with network with the netting twine that inserts network interface by network interface, and its power input obtains electric energy from the AC power of netting twine output, and its power output end links to each other with accumulator.Power circuit comprises that the alternating current with netting twine output is converted to galvanic rectification circuit, and the change-over circuit that this direct current is converted to predeterminated voltage and output.
The power end of operating circuit links to each other with accumulator.Accumulator receives electric energy and stores from power circuit, starts the back at operating circuit and powers for operating circuit.
To sum up, network-termination device of the present utility model can utilize the power line of network line to charge and circuit is powered, and need not to install battery on the equipment, environmental protection, reduction equipment cost.
The above embodiment has only expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
