Abstract:
1. An insulation displacement contact terminal block for providing electrical contact with a bundle of twisted pair wires having at least two differentially driven wire-pairs, a first wire-pair of the at least two wire-pairs diverging form a second wire-pair of the at least two wire-pairs at a diverging point of the bundle of the twisted pair wires, and a first wire of the first wire-pair untwisting from a second wire of the first wire-pair at an untwisting point, a first wire of the second wire-pair untwisting from a second wire of the second wire-pair at an untwisting point, the insulation displacement contact terminal block comprising: a first contact-pair comprising a first insulation displacement contact and a second insulation displacement contact for electrical connection with respective the first and second wires of the first wire-pair; a second contact-pair comprising a first insulation displacement contact and a second insulation displacement contact for electrical connection with respective the first and second wires of the second wire-pair and at least two protruding portions located centrally between the first insulation displacement contact and the second insulation displacement contact of the first contact-pair and second contact-pair, respectively, the at least two protruding portions being shaped so as to facilitate splitting apart the twisted wire pair as the wire pair is inserted into IDC terminal block; wherein the first and second insulation displacement contacts of each of the first and second contact pairs are substantially equidistant from the untwisting point and are proximate to the untwisting point for minimizing crosstalk between the first wire-pair and the second wire-pair, wherein the first and second insulation displacement contacts of each of the first and the second contact pairs are substantially adjacent to each other and the first and second contact-pairs are sufficiently remote from each other for minimizing cross-talk between the first and second wire-pairs and provide minimum degradation of return loss of the circuit defined by each of the first and second wire-pairs.
