ABSTRACT:
A modular telephone plug comprises a one piece insulation housing having a hollow body with two portions, and plural contacts mounted at one end or tip thereof. A first portion accommodates a cable having an outer insulation jacket enclosing a number of individual conductors. A second portion is directly beneath the contacts. A sleeve accommodates untwisted ends of individual conductors extending from the outer insulation jacket. The sleeve is configured to be placed into the second portion to facilitate successful electrical termination of the contacts with the individual conductors accommodated within the sleeve. The sleeve enables shortening of untwisted conductor length used in the connector to a short length, such as in a range below 8 mm and preferably approximately 5 mm, to reduce Near End Cross Talk (NEXT) when data is transmitted by means of the telephone plug, particularly for connectors of Category 5 and higher. The sleeve comprises a hollow insulation element having a number of inner grooves or channels adapted to accommodate each of the individual conductors. By structuring the housing with the first and second portions, the second portion and the sleeve may be shortened. The channels are parallel to each other and in a common horizontal plane, and are aligned with corresponding contacts mounted in the housing. The sleeve includes slots or recesses directly above each of the channels to facilitate successful piercing of the individual conductors by the corresponding contacts during electrical termination.
