Abstract
A modular plug which is fitted in a modular jack so as to connect twisted pair wires is provided. The modular plug comprises a housing, a guide plate which is fitted in the housing so as to separate the twisted pair wires from one another, and terminals and which are connected to electric wires untwisted from the tips of the twisted pair wires, wherein the separated twisted pair wires are held between the internal surfaces of the housing and the guide plate, thereby reducing near end crosstalk and keeping an attenuation thereof within a predetermined range.

A modular plug which is fitted in a modular jack so as to connect twisted pair wires, the plug comprising:
- a housing,
- a guide plate which is fitted in the housing so as to separate the twisted pair wires from one another, and
- terminals which are connected to electric wires untwisted from the tips of the twisted pair wires,
- wherein the separated twisted pair wires are held between the internal surfaces of the housing and the guide plate.
A modular plug which is fitted in a modular jack so as to connect twisted pair wires, the plug comprising:
- a housing,
- an alignment member which is fitted in the housing and has a through hole for holding in alignment eight electric wires untwisted from the tips of first to fourth twisted pair wires at multiple upper and lower levels, and
- eight terminals which are connected to the electric wires untwisted from the tips of the twisted pair wires,
- wherein the through hole is formed such that the inner electric wire of the first twisted pair wire and the adjacent electric wires of the second twisted pair wire are placed at different levels, the electric wires of the third twisted pair wire and the adjacent inner electric wire of the fourth twisted pair wire are placed at different levels, and the electric wires of the second and third twisted pair wires are placed side by side at the same level.
