The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

Example one

As shown in fig. 1, the present embodiment provides an RJ45 connector with an led and a compensation circuit, including:

the voltage-dividing resistor R, the voltage-stabilizing diode D and the two-color light-emitting diode LED are connected in series; the divider resistor R, the voltage stabilizing diode D and the two-color light emitting diode LED are connected between any two transmission lines of the RJ45 connector in series;

and the capacitance compensation circuit is connected to the two transmission lines so as to perform capacitance compensation on the transmission lines.

Specifically, two transmission lines connected with the divider resistor R, the voltage stabilizing diode D and the two-color light emitting diode LED are selected at will, that is, the two transmission lines are selected at will to be connected by using the structure of the existing RJ45 connector without adding any contact point or transmission line on the connector, so that the cost of the connector structure is saved.

Because the divider resistor R, the voltage stabilizing diode D and the two-color light emitting diode LED are connected to the transmission line, the length of the transmission line is unequal, and the transmission performance of the corresponding transmission line is influenced. Therefore the utility model discloses compensate transmission line. Specifically, compensation is performed through a capacitance compensation circuit, and the capacitance compensation circuit is connected to the two transmission lines to perform capacitance compensation on the transmission lines so as to reduce the influence of introduction of a divider resistor R and the like on the transmission performance of the transmission lines. The utility model discloses not prescribing a limit to compensation capacitance, for example, can select "golden finger" electric capacity (tree-shaped electric capacity) or slice electric capacity compensation.

When the tester is connected with the RJ45 connector, a voltage input is provided between two transmission lines which are selectively connected by the divider resistor R, the voltage stabilizing diode D and the two-color light emitting diode LED, when the voltage is input, one LED of the two-color LED will be lighted to indicate that the RJ45 connector works normally, and the detection and management of wiring can be performed. When the LED lamp does not emit light, the voltage of the tester is reversed or the RJ45 connector is abnormal.

The utility model discloses a double-colored LED of two stabilizer blades, double-colored LED lamp are made by two different colours, reverse parallelly connected LED chip an organic whole. When the double-color LED is adopted, when the tester is connected with the RJ45 connector, the voltage between two transmission lines selectively connected by the divider resistor R, the voltage stabilizing diode D and the double-color LED is input, and one LED of the double-color LED can be lightened. That is, one of the LEDs is lit when the power supplies applied to both ends are positive, and the other LED is lit when the power supplies applied to both ends are negative.

For example, when a red-blue two-color LED is used, his two pins are labeled a and B, and if he applies a voltage a positive B negative, he will light red, and conversely if you apply a voltage B positive a negative, he will light blue.

The utility model discloses an adopt double-colored LED, no matter give the selected two transmission line interlines input of connecting of divider resistance R, zener diode D, double-colored emitting diode LED forward voltage or reverse voltage, can both in time show the state of RJ45 connector

The golden needle support is used for fixing the shape and the position of the golden needle terminal; the golden pin terminal is used for connecting the external male connector conductor and the PCB printed board in the female connector; the PCB is used for connecting the gold pin terminal and the IDC terminal, and meanwhile, the capacitor and the electric pole are etched on the PCB to compensate the electrical performance of the whole female head; the IDC terminal is used for connecting an external cable and a PCB printed board in the female head; the circular bayonets are arranged on the IDC terminals, so that when the wire pressing is convenient to install, the core wires can be positioned, and the core wire installation efficiency can be effectively improved. Due to the fact that the gold needle terminals are close to each other, the mutual interference and impedance mismatching of the structure of the gold needle terminals occur during signal transmission due to the fact that the distances between PLUG reeds and IDC terminals are changed with the distance between cables; therefore, the invention adopts the mode of etching the capacitor or the inductor or the coupling line on the PCB printed board, thereby effectively resisting the external interference. As shown in fig. 4, it is preferable that a coupling wire is used as a connection wire between the IDC terminal and the gold terminal.

When the tester inputs reverse voltage, the bicolor light-emitting diode LED can not be lightened. The input forward voltage needs to be readjusted at this point to further determine the operating state of the RJ45 connector. Thus, the present embodiment may employ bi-color LEDs.

The IDC wire clamping cover is used for fixing the position of an IDC metal reed; the IDC metal reed is used for connecting an external cable and a PCB printed board in the male head; the PCB is used for connecting the IDC metal reed and the PLUG reed, and meanwhile, the capacitor and the electric pole are etched on the PCB to compensate the electrical performance of the whole male terminal; the PLUG reed is used for connecting the external female connector and the PCB printed board in the male connector.

On the PCB printed board, a "capacitance" or an "inductance" or a "coupling line" is etched, as shown in fig. 5, a coupling line is used as a connection line between the IDC terminal and the gold pin terminal, which effectively resists external interference.

Preferably, the invention can also adopt a flexible printed board to replace a PCB printed board, when the flexible printed board is adopted, the IDC wire clamping cover of the RJ45 male connector is replaced by a cable branching limiting structure, and accordingly, the RJ45 female connector does not need an IDC terminal any more and directly presses the network cable under the crystal head reed. The remaining components are identical to the RJ45 card using a PCB printed board and will not be described in detail here.

The capacitance compensation unit is connected with the transmission line to be compensated so as to compensate the transmission line.

Specifically, the capacitance compensation unit includes a switch and a capacitor, and the control unit determines whether to perform compensation of a corresponding capacitance value by using the capacitor in the corresponding compensation unit through controlling the switch in the capacitance compensation unit. That is, when the switch is open, the corresponding capacitance compensation transmission line is used, and when the capacitance is closed, the capacitance compensation transmission line is not used.

In order to compensate the transmission line more accurately, a plurality of capacitive compensation units may be simultaneously used to compensate the transmission line. Namely, one or more capacitance compensation units can be selected for compensation by controlling the switches of the plurality of capacitance compensation units so as to adapt to different transmission line requirements.
