COUPLING DEVICE CONFIGURED TO PROVIDE BALANCED COUPLING FOR SINGLE PAIR ETHERNET CABLE

Filed:2024-06-24Pub:2024-12-26
Applicant:BELDEN CANADA ULC

A balancing coupling device is configured to balance electrical coupling of a single pair ethernet cable to a data conductor portion connected with a terminal block connector portion. The balancing coupling device includes a connecting portion structurally configured to connect to a shield portion of the single pair ethernet cable and a balancing coupling portion configured to extend from the connecting portion. The balancing coupling portion includes a first balancing portion and a second balancing portion, the first balancing portion is configured to be connected within at least a portion of a first terminal block connector portion that is configured to be located adjacent to a second terminal block connector portion that is configured to be connected with a first data conductor portion of the single pair ethernet cable, the second balancing portion is configured to be connected within at least a portion of a third terminal block connector portion that is configured to be located adjacent to a fourth terminal block connector portion that is connected with a second data conductor of the single pair ethernet cable, the fourth terminal block connector portion is configured to be located adjacent to the third terminal block connector portion, and the first balancing coupling portion and the second data coupling portion are configured such that the coupling of the first data conductor is balanced with the coupling of the second data conductor so as to reduce alien crosstalk of the single pair ethernet cable.
