Definitions
- the invention relates to the field of electrical engineering and can be used to transmit audio, video and digital signals, to connect speakers to power amplifiers, in radio engineering, electrical engineering and in other fields.
- a two-wire cable is known in the screen, in which there are two current-carrying wires, one of which is a signal one, and the second one is zero.
- the wires are placed in a common shield of electrically conductive material.
- the screen from the input side outside the cable can be connected to the zero conductive wire of the cable or to the body of the signal source.
- the electric field lines are oriented between the signal and neutral wires and between the signal wire and the screen.
- the external electric field is zero. Due to the presence of an electric field dispersed along the entire length of the cable, a dispersed electric capacitance is formed between the signal and neutral wires and an electric capacitance between the signal wire and the screen.
- a three-wire cable is also known in the screen, in which there are three conductive wires, two of which are signal antiphase and one is zero.
- the wires are placed in a common shield of electrically conductive material.
- the screen on the input side, outside the cable, can be connected to the zero conductive wire of the cable or to the body of the signal source.
- the electric field lines are oriented between the signal wires, between the signal wires and the neutral wire, between the signal wires and the screen.
- the external electric field is zero. Due to the presence of an electric field dispersed along the entire length of the cable, a dispersed electric capacitance is formed between the signal and neutral wires and an electric capacitance between the signal wire and the shield [Electric cables, wires and cords: Reference / d.
- the process of recharging the dispersed linear capacitance when changing the polarity of the signal increases the dielectric loss of signal energy in the dielectric, also introducing distortion into the signal, reduces the propagation speed and increases the group delay time of the signal.
- noise generated by molecules of dielectric dipoles is added to the useful signal when the direction of polarization of the dielectric changes.
- Closest to the claimed invention is a typical coaxial cable in the screen, having two wires placed coaxially, and a dielectric layer between them.
- the inner wire of a smaller diameter has a cross section in the form of a circle
- the outer wire of a larger diameter has a cross section in the form of a ring.
- the inner wire is a current-carrying signal
- the external one is a current-carrying zero
- the electric field lines are oriented radially from the internal signal wire to the external neutral wire, along the entire length of the cable.
- the external electric field is zero. Due to the presence of an electric field dispersed along the entire length of the cable, a dispersed electric capacitance is formed between the signal and neutral wires.
- the basis of the claimed invention is the task of creating an electric cable that would improve the quality of transmission of electrical signals by neutralizing the dispersed capacitance with the suppression of stray electrical oscillatory processes.
- the problem is solved in that in an electric cable containing at least two current-carrying wires - signal and zero with dielectric layers between them, according to the invention, the current-carrying wires are separated from each other by at least three dielectric layers and at least two shields of conductive material placed between the layers of the dielectric alternating with them, and along the entire length of the cable, from its entrance to the output, each screen covers only one current-carrying wire connected to it from the input side.
- the problem is solved as follows, in an electric cable containing at least two current-carrying wires - signal and zero with dielectric layers between them, according to the invention, the current-carrying wires are separated from each other by at least three dielectric layers, and at least with two shields of conductive material placed alternately between the layers of the dielectric, each shield is connected to the current-carrying wire through a resistor, and along the entire length of the cable, from its input to the output, each screen covers only one okoveduschy wire connected to it on the input side.
- the screens create an obstacle to the passage of electric field lines between current-carrying wires and neutralize the electric capacitance between them due to the fact that each surface formed by the screen is electrically conductive and is under the same voltage as the current-carrying wire that is separated by this screen.
- the electrical capacitance between the screens does not affect the current and voltage of the signal along the path of its propagation through current-carrying wires, because it is concentrated only at the cable input and its influence is directed only to the signal source. As a result, the quality of transmission of electrical signals is improved.
- connection of the screen with the current-carrying wire through the resistor helps to suppress spurious electrical oscillatory processes that can occur when the output circuits of the signal source and the capacitance interact between the screens, which also significantly improves the quality of transmission of electrical signals.
- Figure 1 shows a first embodiment of a coaxial cable with shielding the signal and neutral wires
- figure 2 is a first embodiment of a two-wire cable
- figure 4 the first embodiment of a balanced cable with shielding two signal wires
- figure 5 is a second embodiment of a coaxial cable with shielding the signal and external neutral wires using a resistor to connect the shield of the signal wire;
- figure 9 is a second embodiment of a three-wire balanced cable with shielding all the wires and using resistors to connect the screens of the signal wires;
- figure 10 the second embodiment of a three-wire balanced cable with shielding all wires and using resistors to connect the screens of all wires;
- 11 is a second embodiment of a three-wire balanced cable with shielding only two signal wires and using resistors to connect the screens of the signal wires.
- Fig.13, Fig.14 and Fig.15 are second embodiments of a two-wire, using a resistor and capacitor, for connecting screens;
- Fig - a second embodiment of a three-wire balanced cable with shielding all the wires, using a resistor and capacitor, to connect the screens of all wires;
- Fig - a second embodiment of a three-wire balanced cable with shielding only two signal wires using a resistor and capacitor to connect the screens of the signal wires.
- the electric cable contains a signal 1 current-carrying wire, a cylindrical screen 2, a neutral 3 current-carrying wire, a dielectric 4, a resistor 5, a capacitor 6.
- a screen 2 for example a cylindrical one, of each wire is supplied with a voltage from the signal source, equal to the voltage on the corresponding signal 1 or zero 3 wire, which is separated by this screen 2.
- the neutralization of the dispersed electrical capacitance between the zero 3 and signal 1 wires eliminates the process of recharging it when the signal polarity changes, which eliminates the dielectric loss of signal energy, distorting the shape of the signal when it passes through the cable, increases the propagation speed and reduces the group delay time of the signal. It also excludes the addition of noise generated by dielectric dipole molecules to the signal when the direction of polarization of the dielectric changes.
- resistor 5 helps to suppress spurious electrical oscillatory processes that can occur when the output circuits of the signal source and the capacitance interact between the screens 2, which also significantly improves the quality of transmission of electrical signals.
