Description

Weak current signal line capable of effectively reducing crosstalk of two channels

Technical Field

The utility model relates to a cable technical field especially relates to an effectively reduce two-channel and cross weak current signal line of twinkling.

Background

Conventional two-channel signals are placed in a single multi-core wire, usually arranged in a cable configuration, most often arranged in groups of two conductors nearby, see fig. 3, often in DIN connectors, keyboard signals, etc. However, in this method, due to the fact that the pairs are arranged side by side at a long distance, the magnetic fields are synchronous, and the pairs interfere with each other seriously, similar crosstalk problems are already verified on the two-channel loudspeaker boxes, and the signal of the other channel is obviously sensed by the line which does not transmit the signal.

Later, two pairs of cables are configured on the RS-422 and DMX transmission protocols, please refer to fig. 4, but in this way, the pair twisting of the cables is not synchronous, so that the effect of magnetic field asynchronization is achieved, and further, the crosstalk is reduced. If used as a streaming show cable, a large amount of filler is required to make up the space, and it is still not effective in balancing the crosstalk resistance and the production feasibility.

Disclosure of Invention

The utility model aims to solve the technical problem that a weak current signal line that effectively reduces two-channel and crosstalk is provided, through two-channel magnetic field mutually perpendicular, play the response minimum and equivalent effect, provide good basis for the differential amplification of balanced transmission.

The utility model provides a technical scheme that its technical problem adopted is: the weak current signal wire comprises a signal wire main body and a connector installed at the end part of the signal wire main body, wherein a first core wire, a second core wire, a third core wire and a fourth core wire are uniformly arranged in the signal wire main body in sequence around the circumference, the first core wire and the third core wire are used for connecting a first channel, and the second core wire and the fourth core wire are used for connecting a second channel.

As to technical scheme a supplement, a stamen line, second stamen line, third stamen line and fourth stamen line be rectangle or rhombus and arrange.

As right technical scheme a supplement, the connector on be provided with the contact pin of being connected with first stamen line, second stamen line, third stamen line and fourth stamen line one-to-one.

Has the advantages that: the utility model relates to an effectively reduce two channels and crosstalk's weak current signal line, first stamen line and third stamen line are used for first access connection, and the second stamen line and fourth stamen line are used for the second access connection, through two channels magnetic field mutually perpendicular, play the response minimum and equivalent effect, provide good basis for balanced transmission differential amplification.
