Abstract

The present invention relates to a twisted pair cable in which a shape of a separator for separating a plurality of pairs of wires apart from each other is changed and which is thus easy to manufacture, has a simple configuration, and minimizes internal interference between the pairs of wires.

First claim

1 . A twisted pair cable comprising:
a plurality of pairs of wires, each of which is formed by spirally twisting two wires together, each of the two wires including a conductor covered with an insulator; a separator disposed between the plurality of pairs of wires, the separator including a plurality of spacers radially formed to separate the pairs of wires apart from each other; and an outer jacket surrounding outsides of the plurality of pairs of wires and the separator, wherein at least one spacer among the plurality of spacers of the separator is different in thickness or length than the other spacers.

2 . The twisted pair cable of claim 1 , wherein at least one spacer among the plurality of spacers of the separator is shorter in length than the other spacers.

3 . The twisted pair cable of claim 1 , wherein at least one spacer among the plurality of spacers of the separator is greater in thickness than the other spacers.

4 . The twisted pair cable of claim 1 , wherein at least one spacer among the plurality of spacers of the separator is greater in thickness than the other spacers and is shorter in length than the other spacers.

5 . The twisted pair cable of claim 2 , wherein a length of the at least one separator which is thicker and shorter is greater than a diameter of the wire which consists of pairs of wires.

6 . The twisted pair cable of claim 1 , wherein cross-sectional areas of four spacers with respect to a point of intersection on center lines of the spacers in a thickness direction correspond to each other within a predetermined error range.

7 . The twisted pair cable of claim 6 , wherein the predetermined error range is 25%.

8 . The twisted pair cable of claim 1 , wherein the plurality of pairs of wires are each formed by twisting two wires together at different pitches, and
the at least one spacer different in thickness or length than the other spacers is disposed between pairs of wires having a minimum pitch deviation among the plurality of pairs of wires.

9 . A separator for separating pairs of wires of a twisted pair cable apart from each other, wherein the twisted pair cable comprises four pairs of wires, and
the separator comprises four spacers forming a cross-shaped cross-section together, wherein at least one spacer among the four spacers is different in thickness or length than the other spacers, wherein cross-sectional areas of the spacers with respect to a point of intersection on center lines of the spacers in a thickness direction correspond to each other within a 25% range.
