Abstract
A power over ethernet (POE) device with a lightning protection circuit of a data extractor comprises a power circuit (1) and a data extractor circuit (2), and the data extractor circuit (2) comprises a network transformer (21). The device is characterized in that the data extractor circuit (2) is connected with a lightening protection circuit (3), and the lightening protection circuit (3) is a transistor discharging lightening protection circuit and is installed at an output end of a network transformer (21). The POE device is provided with the lightning protection circuit of the data extractor, lightning protection treatment is performed on the data circuit, and the device is prevented by being damaged from lightening. Particularly, the network transformer can be effectively protected.
Description
[technical field]
The utility model relates to shocking preventing technology and ethernet technology field, refers to a kind of POE equipment that has the data extractor lightning protection circuit especially.
[background technology]
Along with Ethernet is used more and more widely, the network ' s thunder of Ethernet is also more and more higher compels.Ethernet network device such as wireless router, IP phone machine, network camera, wireless bridge, cashier's machine etc. comprise switching power circuit and Ethernet data splitter circuit; These POE equipment of prior art have only been done the lightning protection of power unit; The data extractor circuit is not done lightning protection and is handled; The data extractor circuit block receives thunderbolt easily and damages, and the parts that damage the most easily are exactly network transformer.
[summary of the invention]
To the shortcoming of prior art, the purpose of the utility model is to provide a kind of POE equipment that has the data extractor lightning protection circuit.
The utility model solves the technical scheme that its technical problem adopted: a kind of POE equipment that has the data extractor lightning protection circuit is provided; Comprise power circuit and data extractor circuit; Include network transformer in the data extractor circuit; It is characterized in that: said data extractor circuit is connected with lightning protection circuit, and this lightning protection circuit is a transistor discharge lightning protection circuit, is loaded on the output of network transformer.
When sensing high voltage or electric current on a certain circuit on the data circuit, this voltage will be responded to coil one end on the network transformer, and the crystal discharge tube will be to other end conducting discharge, and electric current just can not be through the coil of network transformer.The conducting voltage of crystal discharge tube is very low, about 10V, so can play a very good protection
The beneficial effect of the utility model is: data circuit is done lightning protection handle, make equipment avoid thunderbolt and damage.Effective protecting network transformer particularly.
[description of drawings]
Below in conjunction with accompanying drawing the utility model is done further to describe.
Fig. 1 is the electrical block diagram of the utility model;
Fig. 2 is the lightning protection circuit electrical schematic diagram of the utility model.
Among the figure: 1 is that power circuit, 2 is that data extractor circuit, 3 is that lightning protection circuit, 21 is that network transformer, 31 is discharge transistor.
[embodiment]
Referring to accompanying drawing; A kind of POE equipment that has the data extractor lightning protection circuit of the utility model; Comprise power circuit 1 and data extractor circuit 2, include network transformer 21 in the data extractor circuit 2, it is characterized in that: said data extractor circuit 2 is connected with lightning protection circuit 3; This lightning protection circuit 3 is transistor discharge lightning protection circuits, is loaded on the output of network transformer 21.
When sensing high voltage or electric current on a certain circuit on the data circuit, this voltage will arrive coil one end on the network transformer 21, and crystal discharge tube 31 will be to other end conducting discharge, and electric current just can be through the coil of network transformer 21.Can play a very good protection.
