Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail.

As shown in Figure 1 and Figure 2, a kind of multi-functional 2XN RJ45 POE PCB modules, including mainboard chip, net mouth transformer 1st, RJ45 adapters, power management chip, LED pads 2, RJ45 printed circuit board (PCB)s（Printed circuit board (PCB) abbreviation PCB）, the PCB3 Upper to include LED pads 2 and RJ45 high-speed-differentials line 4, the primary tap of the net mouth transformer 1 is connected with power management chip, Holding wire in the primary of the net mouth transformer 1 is connected with RJ45 adapters, and the secondary of the net mouth transformer 1 passes through network interface Primary signal line 5 in the primary of transformator is connected with mainboard chip, and release electricity is connected in the primary tap of net mouth transformer 1 To the first discharge tube 7 of the earth, the RJ45 high-speed-differentials line 4 is passed through between adjacent LED pads 2, the pad of each LED 2 longitudinal directions are arranged on the PCB3 and parallel with the RJ45 high-speed-differentials line 4, are connected between RJ45 windows and pin contact pin, Together with front lock pin module and rear lock pin module are welded to each other by transformator module, then with HOUSING supports by the company of lock Connect and combine, then the shielding shell of shielding action is played in external mounting, connected with constituting a complete 2XN RJ45 POE Connect device finished product.Secondary signal line 6 in primary signal line 5 in the primary of net mouth transformer and net mouth transformer secondary it Between be provided with the second discharge tube 8, secondary signal line 6 releases the 3rd discharge tube 9 for discharging into the earth, the LED to being additionally provided between ground For 2 pins or 3 pins.

In the present embodiment, the first discharge tube 7 that the primary tap of net mouth transformer 1 is connected to may be selected the half of 110V conductings Conductor TVS pipe（Transient Voltage Suppressor, transient voltage suppressor）.When external lightning hits net Line, when electric current is flowed into net mouth transformer primary tap by netting twine, when voltage herein is more than 110V, is connected on net mouth transformer Primary tap is to the TVS pipe between ground（That is discharge tube）Can immediately turn on, make immediate current flow into casing by quasiconductor TVS pipe Ground, during the ground of the Nature is exported to finally by casing.Such as need to consider electric lines of force AC220V overlap joint risk, partly leading herein Body TVS pipe is replaced by the quasiconductor TVS pipe of 400V conductings.

Due to net mouth transformer 1 voltage isolation may do it is unsatisfactory so that the secondary of net mouth transformer 1 thunderbolt Moment can also be coupled into carrys out a part of residual voltage, therefore, it is necessary to increase by the second discharge tube 8 in the secondary of net mouth transformer, Specific structure is that the second discharge tube 8 is connected between the secondary signal line 6 in secondary, and secondary signal line 6 is connected to again between ground 3rd discharge tube 9.When the residual voltage of 1 level of net mouth transformer（Pressure reduction, holding wire between holding wire line and line with systematically Between pressure reduction）5V or more than 5V is reached, internal corresponding discharge tube will be turned on, this portion of residual voltage is promptly discharged To systematically going up.

Above-described embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with this field skill The personage of art will appreciate that content of the present utility model and is carried out, and can not limit protection model of the present utility model with this Enclose, all equivalence changes made according to this utility model spirit or modification effect are similar, all should cover in this utility model Protection domain in.
