Abstract

A modular connector comprises an insulating housing (100) having a plugging portion for plugging with a mating connector, a plurality of contact elements (201-208) supported by the insulating housing, the contact elements each having a contact section (201a-208a) arranged in the plugging portion, an intermediate section (201B-208B) secured to the insulating housing, and a connection section (201C-208C) extending from the intermediate section, a pair of the contact elements (201, 208) on opposite ends being twisted to intersect each other in the intermediate sections, the other pairs of the contact elements (202-207) being arranged such that the distance between adjacent contact elements decreases in the intermediate sections and increases in the connection sections.

Claims

1. A modular connector comprising:

an insulating housing having a plugging portion for plugging with a mating connector;

an array of contact elements supported by said insulating housing;

said contact elements each having a contact section arranged within said insulating housing in a substantially parallel, laterally spaced relationship, an intermediate section extending from said contact section being laterally flat and fixed in said insulating housing, and a connection section extending from said intermediate section;

two pairs of said contact elements, one on each opposite end of said array, intersecting each other in said intermediate sections and arranged such that a lateral distance between said contact elements of said each of said two pairs is increased in said intermediate sections compared with a lateral distance between said contact sections; and

other pairs of said contact elements arranged such that a lateral distance between said contact elements of each of said other pairs is decreased in said intermediate sections compared with a lateral distance between said contact sections and increased in said connection sections.

2. A modular connector according to claim 1, wherein one of said pairs of said contact elements is made from a first reed frame, and the other from a second reed frame, with one of said first and second reed frames being substantially flat.

3. A modular connector according to claim 1, wherein said intermediate sections are molded with said insulating housing, with said connection sections bent in an L-shape from said insulating housing.

4. A module connector according to claim 3, wherein said lateral distance of said contact elements of said other pairs is increased after said L-shaped bends.

5. A module connector according to claim 3, wherein said connection sections of said contact elements permit mounting on a board up to said L-shaped bends so that a height of said module connector is minimized.

6. A modular connector according to claim 3, wherein said insulating housing has said plugging portions at two tiers, said contact elements being provided in each of said tiers, and the connection sections of said other pairs of said contact elements are spaced in each of said tiers so as to optimize crosstalk characteristics.
