A modular jack and a modular jack connector which are suitable for use in twisted pair wiring system and suppress coupling in and out of a modular jack are provided. A modular jack, comprising, a hollow housing of which one end is opened, and eight conductor pins which are arranged with predetermined intervals to right and left directions inside said housing, each of said conductor pins has bending portion projecting toward said opening portion (this direction is defined by 'forward'), lower part of said each conductor pin corresponds to a conductor pin leg which passes through bottom of said housing, when numbers from No. 1 to No. 8 are given respectively to said each conductor pin starting from right, each set of conductor pins of No. 1 and No. 2, No. 3 and No. 6, No. 4 and No. 5, and No. 7 and No. 8 is used respectively as conductor pair, bending portions of said No. 3 and No. 6 conductor pins are positioned more forward than bending portions of other conductor pins, and conductor pin legs of said No. 3 and No. 6 conductor pins are positioned more forward than conductor pin legs of other conductor pins.

Modular jack and modular jack connector

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.

Modular plug

A modular jack and a modular jack connector which are suitable for use in twisted pair wiring system and suppress coupling in and out of a modular jack are provided. A modular jack, comprising, a hollow housing of which one end is opened, and eight conductor pins which are arranged with predetermined intervals to right and left directions inside said housing, each of said conductor pins has bending portion projecting toward said opening portion (this direction is defined by &ldquo;forward&rdquo;), lower part of said each conductor pin corresponds to a conductor pin leg which passes through bottom of said housing, when numbers from No. to No. are given respectively to said each conductor pin starting from right, each set of conductor pins of No. and No. , No. and No. , No. and No. , and No. and No. is used respectively as conductor pair, bending portions of said No. and No. conductor pins are positioned more forward than bending portions of other conductor pins, and conductor pin legs of said No. and No. conductor pins are positioned more forward than conductor pin legs of other conductor pins.

A method of making an electrical connector comprises assembling a frame mold ( ) having front, rear, and bottom openings, a front mold ( ) attached to the frame mold ( ) from front and having a channel ( ) for receiving the flexible section ( ) and a portion of the intermediate section ( ) of a terminal corresponding to the flexible section ( ), a rear mold ( ) attached to the frame mold ( ) from rear and having a comb section ( ) entering between the intermediate section ( ) and the flexible section ( ), and a bottom mold ( ) attached to the frame mold ( ) from below and having an upper support face ( A) for supporting the intermediate section ( ) of the terminal.

Electrical connector and method of making the same

The terminals ( ) are supported by the housing ( ) at the middle sections ( C, C). Each of the terminals ( ) has a contact section ( A, A) bent into the receiving cavity ( ) of the housing ( ) after integral molding with the housing ( ).

Electrical connector and method of making same

A harnessed modular plug (,) includes at least first and second pairs of wires,); a guide plate (,) having at least two pairs of guide apertures (,) capable of arranging the wires of the first and second pairs in at least upper and lower rows; a housing (,) for receiving the guide plate; and at least two pairs of terminals (,) provided in the housing (,) at positions corresponding to the guide apertures (,). The wires (,) of the first pair are arranged next to each other while the wires (,) of the second pair are spaced across the first pair (,) in the same row.

Modular plug and harnessed plug

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