Description
Technical field
The utility model relates to the improved circuit that a kind of network signal is handled, especially refer to utilize inductive bank to improve the treatment circuit of voltage difference, circuit path between network connector and coupling capacitance is provided with inductive bank, and behind the power supply that inductive bank received signal coupling capacitance provides, because of inductance characteristic produces back electromotive force, and can keep transmission signals complete, undistorted, and reduce power loss.
Background technology
The fast development of computer technology now, and desktop computer or notebook computer general be present in each corner in the society, its computer development trend is also strong towards calculation function, speed reaches the little direction of volume soon and strides forward, because during network communications technology is also flourish rapidly, and people are lived, study, work is brought another different brand-new boundary in the past into leisure, make between men and can transmit required instant messages mutually through network communication, advertising or contact mail etc., simultaneously by the various information of Web search, instant messaging or online game etc. allow relation more hot network and inseparable between people and the network.
But the part of network is transmitted data for two kinds of modes such as connection of the cable of use and wireless transmission are arranged, the cable interconnection technique just need be equiped with network connector, along with the utilization of network is more and more wider, the data capacity of transmission over networks is also increasing, network vendors is just drawn high the speed of Network Transmission always for the demand that satisfies the user, from 10Mbps to 100Mbps or 1Gbps, even the present fiber optic network transmission speed of releasing can reach more than the 10Gbps, yet, when network transfer speeds is 10Mbp s, its coded system is with Manchester (Manchester code) compiling method, because the signal waveform on the cable is (the seeing also shown in Figure 7) that is symmetry shape, so when distorted signals or reception error in data, just can utilize symmetry characteristic to carry out signal compensation, so that can obtain complete and correct signal data; And when network transfer speeds is 100Mbps, its coded system is with the compiling method of three kinds of potential level (3-levelternary code), the bit string is cut into one group of per eight bit, each group then is converted to the character code with 6 symbols, allow required sequential rate be reduced to 25MHz, so just can not surpass the patient 30MHz limit of twisted-pair feeder by 33 ﹒ 3MHz.
Yet, in network transfer speeds is that 1Gbps utilizes the sequential rate to be 125MHz, its coded system is to use five level 4D-PAM5 coding, each level is represented a symbol, each symbology 2 order information, by this Signal Compression is strengthened to accelerate transmission speed, but its signal waveform is not symmetry shape (seeing also shown in Figure 8), in order to allow the network signal (negative voltage partly) can be not cut and distortion or inefficacy, so just will add that bias voltage is positioned at the positive voltage zone by signal and can transmits smoothly.
Therefore, the legacy network connector is for having transformer module, see also shown in Figure 9, the practice of general manufacturer is that transformation coil B and filter coil C are installed on the circuit board A, and transformation coil B and filter coil C are arranged with lead D1 on core D, the joint of lead D1 end is welded in the contact of circuit board A, because coil needs to cause production efficiency low with manual the winding, more can't automated production, coil also ruptures easily and allows cost improve, and what twine is tight, distance, differences such as the number of turns also can impact effect, and causes product quality very different.
Moreover, the utility model applicant once proposed novel patent application with " network signal treatment circuit " to TaiWan, China, application case number No. 101207955, and neck is demonstrate,proved several M436860 number of patent gazette certificate number, see also shown in Figure 10, it is to electrically conduct respectively between network connector E1 and network chip E2 in signal processing circuit E two ends, be provided with a plurality of circuit path E3, and on a group or more circuit path E3, be electrically connected with signal coupling capacitance E4 respectively, electrically be provided with the inductive bank E5 that is series connection again, and inductive bank E5 electrically connects bias voltage feed end E51, electric capacity of voltage regulation E52 and earth terminal E53, to see through the direct current quasi-position that bias voltage feed end E51 provides, can provide to circuit path E3 by inductive bank E5, then the voltage quasi position because of bias voltage makes the signal that transmits among the circuit path E3 be arranged in the positive voltage scope, can not be positioned at negative voltage range and cut generation distortion, and then reach the purpose that signal integrity transmits and receives; But because of bias voltage feed end E51 power supply to inductive bank E5, inductive bank E5 has again direct voltage is short-circuit condition, the characteristic that the high-frequency signal that exchanges is open-circuit condition, and because of inductive bank E5 connects bias voltage feed end E51, and provide the electric current inductive bank E5 that flows through by bias voltage feed end E51, cause inductive bank E5 to reduce inductance sense value because of material behavior, so bias voltage just can pass through inductive bank E5 smoothly, and the high frequency network signal of inductive bank E5 two ends then can be intercepted and can't be passed through, so voltage signal just only can transmit in circuit path E3, and then avoid voltage signal to be shunted ground connection and weaken, and utilize electric capacity of voltage regulation E52, the magnitude of voltage of earth terminal E53 balancing circuitry passage E3, but the power supply that also causes bias voltage feed end E51 to be supplied is grounded, and promptly produces the severe attrition of power.
Therefore, how to solve the problem and the disappearance of existing transformation coil, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
